(57) Abstract:

Usage: in devices for cleaning gravel tracks from pollutants. The inventive machine comprises a frame mounted on the undercarriage, on which are mounted two rotary intake body and the treatment device in the form of a moving mesh belt conveyor for feeding the contaminated ballast conveyor for discharging crushed stone, collection of litter, rigid sleeves with curved according to the radius of the end part of the valve and the metering device. In screening the ballast includes an opening area of a mesh tape on which the ballast is subjected to the greatest inertia loads in the transverse previous movement direction.

The invention relates to railway transport, namely, devices for cleaning gravel tracks from contaminants.

Known design webpagetitle machine containing the n hopper with metering mechanism, on the end wall which is mounted to rotate a cylinder inclined tray [1].

Due to the use of continuous pallet does not provide the reliability of the machine.

The most famous design webpagetitle machine is a machine that contains a frame with the rotor, the treatment device in the form of a mesh tape with horizontal and vertical direction on a frame which is a collection of weeds, which includes a conveyor on the frame of the latter is rigidly fixed rack pivotally connected with the spring loaded reflector pollutants. Additionally, the collection of litter is installed with the possibility of reciprocating movement in a horizontal plane under the treatment device and above the conveyor for discharging pollutants [2].

This design is complicated, not effective, does not provide reliability webpagetitle machine.

The present invention is directed to simplifying the design webpagetitle machine, improving the efficiency of clearing rubble and reliability of its work.

This is achieved by the fact that in the screening included the initial part of the mesh tape on which the ballast on the large number of weeds in the initial horizontal section provides a reduction in the number of weeds, screened next, and this leads to simplification of the structure; there is no need to stand, reflector. Compendium of weeds becomes stationary due to the rigid mounting rails. Form bent on a radius of the end parts of the rigid guides in place of changing the direction of the mesh belt from horizontal to vertical contributes to a more reliable operation of the net tape, because the sliders in the area of the greatest centrifugal forces rely on the curved end portion. The collection of litter made side opening without spring reflector that allows you to delete some of the pollutants through the open door, bypassing the carriers.

In Fig. 1 shows a General view webpagetitle machine; Fig. 2 - treatment device with a collection of weeds; Fig. 3 is a view of A in Fig. 2.

On the frame of the cleaning device made in the form of a mesh tape with horizontal and vertical direction 4 is mounted stationary compendium of weeds 7 in the form of a conveyor belt with the possibility of opening the valve. The collection of litter is equipped with a pallet in the form of fixed guides under the bearer's mesh tape with a curved radius end parts.

Subpotential machine operates as follows.

Before you begin the flap 14 compendium of weeds 7 is set to the closed position. When driving the rotary intake body 3 cuts polluted ballast at the ends of the sleepers and unloads it on the conveyor 5, which takes the dirty gravel on the treatment device 4 in the form of a rotating mesh belt 12 moving in the transverse in relation to the flow of rubble direction. Shock acceleration of particles of crushed stone at the moment is) screening occurs due to the action of gravitational forces down through the mesh tape 12 in the intermediate space between the guide rails 9 on the conveyor 8, which passes the pollutants on the conveyor for subsequent loading in rolling stock. On the conveyor 8 are particles of contaminated rubble, emitted under the action of centrifugal forces through the vertical grid line cleaning device after it hits the valve. To ensure reliable operation of the net tape 12 her side bearings 11 in the zone of the highest centrifugal forces rely on curved on the radius of the end part of the rigid guides. Cleaned the gravel is fed into the dosing device 13, and in the way.

Possible variant removing particle contaminants through the open valve 14 on the side of the road, bypassing the carriers.

Techno-economic comparison webpagetitle machine makes it possible to identify a number of advantages of this solutions:

a) simplified design webpagetitle machine, namely the collection of litter;

b) improved quality of clearing rubble, before the arrival of bursts on the path increases;

C) reliability is improved webpagetitle machine due to exceptions in the LASS="ptx2">

SUBSTANCE: : invention relates to environment protection, in particular to purification of rubble and/or asbestos rail ballast from pollution with oil and can be used on rail transport. Siftings of rubble and/or asbestos rail ballast are loaded into device for washing. Washing of ballast siftings is carried out by mechanical mixing with detergent solution. After washing ballast siftings and polluted detergent solution are removed together and separated. During separation ballast siftings are separated into fractions and removed in order to be used in proper way. Separated polluted detergent solution is supplied through nozzles into precipitation tank of centrifugal type for pollution by separating phases. From precipitation tank separated oil products, detergent and sludge are removed in separate flows. Sludge is dehydrated and after that neutralised using chemical reagents. Detergent solution is subjected to purification from heavy metal salts and residual oil products. Formed deposit of heavy metal salts is periodically removed to the stage of sludge neutralisation. Purified detergent solution is supplied again to the stage of mechanical washing of ballast siftings. Before supplying detergent solution to the stage of washing, technical detergent which does not require water heating is introduced into it.

EFFECT: high degree of ballast siftings purification is achieved with simultaneous efficient phase separation, reduction of dangerous wastes formation and energy consumption for the process.

SUBSTANCE: proposed method consists in that granular loose material is compacted and/or cleaned of impurities by forcing pressurised medium in material layer prior to and/or during processing. Said forced medium can represent gas and/or fluid and/or mix thereof except for cleaning wherein fluid and/or gas-fluid mix is used as said forced medium. Composition of forced medium is varied during processing granular loose material. Said medium is forced into granular loose material in steady-state or pulsed conditions, pulsation being caused by fed medium pressure variation and/or by alternating medium feed and feed stoppage intervals. Said medium is fed under pressure that ensures quasi-liquefaction of granular loose material.

EFFECT: reduced friction between material grains that minimises complex spatial motion of said grains.

SUBSTANCE: proposed method comprises complete cutting-out of ballast, its cleaning, filling lower layer to be leveled and compacted, filling new layer of breakstone thereon. Compaction of ballast lower layer is carried out by vertical static and dynamic effects brought about by wedge-like compactors on ballast surface in zones between sleepers. Said wedge-like compactors are mounted on breakstone cleaning or special ballast-compacting machine. New layer of breakstone is compacted by hammering machine and dynamic stabiliser that transfers vibration onto assembled rails and sleepers and onto breakstone ballast.
