The invention relates to the field of cleaning equipment and can be used in devices designed to collect various contaminants in industrial premises, including fire and explosion.

Known ejector vacuum cleaner containing a sealed body, the top cover, filters, and an ejector associated with the sealed enclosure through the check valve (patent No. 2135065, CL A47L 5/18, "Universal ejector vacuum cleaner to collect various contaminants", 27.08.99). During operation of the vacuum ejector creates a vacuum in the sealed enclosure, where does polluted air, after passing through the filters.

Closest to the proposed invention on a set of attributes is a vacuum cleaner, comprising a housing, an ejector and a filter connected to the mixing chamber of the ejector (patent No. 2069062, CL A47L 5/18, "Cleaner", from 20.11.96). This vacuum cleaner a dirty air enters directly into the cavity of the housing and passing through the filter and the ejector vented to the atmosphere through the filter damper.

The disadvantage of the above-described vacuum cleaners is the fact that in the course of their operation is necessary to periodically remove the filters and remove mechanical impurities, and the smaller the particle size of the collected dirt, the more often you have to clean the filters.

T the economic impact of the proposed technical solution is the improvement of performance characteristics of vacuum cleaner and simplified maintenance.

This technical result is achieved by the fact that industrial vacuum cleaner, comprising a housing with a lid, the main ejector, suction hose with nozzle and located in the housing cavity, two filters, each filter coupled to the output of the corresponding auxiliary ejector, and the passive input of each of the auxiliary ejector communicates with the atmosphere; the passive input of the main ejector is connected with the suction hose, and the output of the main ejector is installed valve, made in the form of an elastic element; one of the outputs of the jet trigger With separate inputs connected to the input of inkjet discrete monostable element and through the first delay element, with the control the input of the first valve, the second output of the jet trigger with separate inputs connected with the control input of the second valve, direct inkjet discrete monostable element via a second delay element connected to the input of the jet trigger with separate entrances, which he turns into when compressed air is supplied to the control input of the second valve, inverted output inkjet discrete monostable element through the third delay element is connected to a second input of the jet trigger with separate inputs, the output of the second paragraph is emerspecies, the corresponding atmospheric input, connected to an active input of the basic ejector, and the second output of this valve is connected to the supply input of the first valve, each of the outputs of the first valve is connected with the active input of one of the auxiliary ejectors; installed in the housing clamp capacity.

The introduction of auxiliary ejectors, delay components, pneumatic and fluidic elements allows automatic cleaning of the filters in the process that enables continuous, over a long period of time to collect even fine dirt. Install quick-release capacity simplifies maintenance of the vacuum cleaner.

The figure depicts an industrial vacuum cleaner.

The vacuum cleaner includes a housing 1 with a cover 2. On the cover 2 has a main ejector 3, the filters 4, 5 and auxiliary ejectors 6, 7. As an auxiliary ejectors can be used ejectors type IP (Jet logic elements and devices for automatic control of technological equipment. The branch directory. Edited Eigin, M.: VNIIEM, 1989). Passive input (i.e. input, in which a vacuum is created) primary ejector 3 is connected to the suction hose 8 with the nozzle 9. Active input (i.e. the input to which is fed the high is providing the primary ejector 3 is connected to the output of the valve 10, and active outputs auxiliary ejectors 6, 7 are connected to the outputs of the valve 11. As pneumatic spreaders can be used two-position four way valves with one-way pneumatically operated and spring return. Passive inputs auxiliary ejectors 6, 7 are communicated with the atmosphere. The pneumatic control is performed using the ink-jet trigger with separate entrances 12, inkjet discrete monostable element 13 and the delay elements 14, 15, 16. As fluidic elements (position 12 and 13) can be used for elements of type ARTICLE series "VOLGA" (Jet logic elements and devices for automatic control of technological equipment. The branch directory. Edited Eigin, M.: VNIIEM, 1989). As the delay elements can be used pneumatic relay time of different designs. The output of the main ejector 3 has a valve 17, made in the form of an elastic element. In case 1 posted by quick tank 18.

Industrial vacuum cleaner works as follows.

In operation, the vacuum is alternately changing modes: mode suction and cleaning mode (purge filters). Therefore, before you begin you must configure time suction (delay element 6), the total time of the purge filter (delay elements 15 and purging of the first filter (delay element 14). The total purge time should be approximately twice the time of the blowing of the first filter.

When applying the cleaner, pneumopathy, the supply air supplied to the jet trigger with separate entrances 12, may begin to flow in one of two outputs of this element. Assume that the compressed air began to flow from the output connected with the control input of the valve 10. The valve 10 switches, and the compressed air will act on the active input of the main ejector 3. On the passive input of the ejector 3 is formed a vacuum, and the output of the ejector - excess pressure valve 17 opens. Through the nozzle 9 through the hose 8 will begin the absorption of various contaminants in quick tank 18. Passing through the filters 4, 5 purified air through passive inputs (atmospheric holes) auxiliary ejectors 6, 7 emitted into the atmosphere. Simultaneously with the beginning of the suction process of the inverted output of the jet discrete monostable element 13, the compressed air will flow to the input of the delay element 16 and will begin the countdown suction. After a time the suction from the output of the delay element 16 to the input of the jet trigger with separate entrances 12 will be compressed air, and three the ger will switch.

After the switch trigger with separate entrances 12, the following occurs. First, disconnect the valve 10 will stop the air supply to the main ejector 3, the valve 17 will be closed. At the same time the compressed air from the valve 10 through the valve 11 will arrive at the active input auxiliary ejector 6 and will begin flushing the filter 4. Secondly, to the input of the delay element 14 will be compressed air and will begin the countdown purge filter 4. Thirdly, the compressed air is fed to the input inkjet discrete monostable element 13. The element will switch, and with its direct output compressed air is fed to the input of the delay element 15. Begin timing the total purge (purge both filters).

After the time of the blowing of the filter 4 to the control input of the valve 11 from the output of the delay element 14 will be compressed air, and the valve switches. Compressed air will act on the active input of the auxiliary ejector 7, and will begin flushing the filter 5. In the process of purging each of the filters, the flow rate of compressed air supplied to the purge, increases due to ejection of atmospheric air through the atmospheric channels (passive input) of the corresponding auxiliary ejector. Thus, the filters alternately blown. In the process of purging CL the pan 17 is closed and the bleed air in the atmosphere is produced through the auxiliary ejector filter, which at the moment is not blown. After a total time of blowdown from the output of the delay element 15 to the input of the trigger with separate entrances 12 will be compressed air. The trigger switch in the initial state, and starts sucking. Then the cycle repeats.

If upon initial filing of pneumopathy trigger with separate entrances 12 will be set in a state in which the compressed air begins to flow from the output of the trigger associated with the delay element 14, the operation of the cleaner will begin with purge mode filters.

After work, opening the cover 2, remove quick-release tank 18 and cleanse them from pollution.

Thus, in the process, industrial vacuum cleaner, periodically cleaned automatically (purge) filters. The desired absorption time and purge time are set using delay elements. The magnitude of the vacuum generated by the main ejector, can be adjusted by changing the pressure of compressed air supplied to the valve. Especially effective is the use of this industrial vacuum cleaner when collecting fine dirt.
