The invention relates to agriculture, namely, to obtain briquettes for heating, which allows the use of local resources in the form of easily accessible and environmentally friendly materials.

A device for briquetting of solid waste, including the camera and hydraulic press with pressure plate, hydraulic press mounted vertically in the lower part of the device under the pressure cooker. (EN 67507 U1, IPC 6 C25C 122, publ. 27.10.2007,)

Known briquetting press feed containing hopper, a housing with a discharge window and the rotor is mounted with its surface blades, placed in the enclosure to form between them an annular cavity (EN 2347679 C1 IPC B30B 11/14, publ. 27.03.2009,).

The disadvantage of the above devices analogues is that you cannot use for briquetting of waste animal waste (manure, dung), and the complexity of their design.

Closest to the proposed device is a device for briquetting, containing mounted in the hollow body of the conical auger, hopper, part of the bottom wall of the case is made in the form of a scraper conveyor, the drive of which is located outside the housing (EN 108339 U1, IPC B30B 9/14, publ. 13.04.2011,).

The disadvantage of the prototype is the inability to b is tetralani waste animal waste (manure, litter), as well as the complexity of the design.

The objective of the proposed device for briquetting waste of animals and birds is the implementation of briquetting of waste animal waste (manure, dung).

The technical result is achieved due to the fact that the device comprises a hopper mounted in the hollow body taper screw located in the lower part of the body of the scraper conveyor, from the apex of the cone of the screw at the outlet of the housing features a spring-loaded plate in the form of skiing, but unlike the prototype, it further comprises a mixer consisting of a body, nipples input aggregate and filler, and along the vertical axis of the body of the mixer is placed rotor with four blades arranged at an angle to each other, the lower part of the mixer through the gate and the pipe connected with the lower part of the device for mixing the material with a binder consisting of a rectangular body and pipe input connecting the inside of the case, inside the case on its opposite sides has two screw in the form of spirals with opposite winding, rotating by electric motors, with the outer side of the device for mixing at its perimeter is the coil with the coolant.

In addition, the blades are mounted is on the rotor of the mixer have the shape of a rectangular triangle.

The ultimate strength in compression is one of the main indicators of the quality of the briquettes. The reduction of tensile-compression causes losses during storage and transportation of bricks, and the littering fines. This complicates their use as fuel.

For making briquettes were used cattle manure and sawdust softwood, which is the waste wood processing industry. The preparation of the mixture to the briquetting was the drying of manure and mixing it with sawdust softwood in the amount of 0, 10, 25 wt.%, and humidified before 10-23% clay, wt.% 8-10. The resulting mixture was heated to a temperature of 20-25°C and bitterbal. Briquetting was carried out at a pressure of 10 MPa. The moisture content of sawdust is 22.8%, clay - 10-13%. After briquetting was determined by the mechanical strength of the briquettes in compression according to GOST 21289. In the result, it was found that the briquettes have mechanical strength in compression 12-15 MPa.

The device shown in Fig., includes hopper 1, mounted in the hollow body 2 taper screw 3, located in the lower part of the body of the scraper conveyor 4, the apex of the cone of the screw at the outlet of the housing features a spring-loaded plate 5 in the form of skis. The device additionally content the t mixer 6, the motor 7, the nozzle 8 input filler pipe 9 input filler along the vertical axis of the housing, the rotor 10 with four blades 11, a gate 12, a pipe 13, a device 14 for mixing the material with a binder consisting of a rectangular body 15, the nozzle 16 input binding, screws 17 and 18 in the form of a spiral on the left and right winding, electric motors 19 and 20, the device for mixing the material with a binder is surrounded by a coil 21 with the carrier.

The device operates as follows.

Through pipe 8 raw dried filler in the form of manure is fed into the housing 6 of the mixer. At the same time, through pipe 9, the filler in the form of sawdust is fed into the housing 6 of the mixer. The rotation of the motor 7 is transmitted to the rotor 10 and blades 11. Rotating, the blades 11 are mixed filler and filler into a homogeneous mixture. Opens the gate 12 and the mixture moves by gravity to the bottom of the device 14. From the opposite side through the pipe 16 serves binder in the form of clay.

The rotation motor 19 is transmitted to the screw 17, having a left-hand wound. The mixture of filler and filler, auger 17 will mix up and then falls under the action of gravitational forces on the bottom of the device for mixing the material with a binder. Simultaneously, the rotation of the motor 20 lane is given to the screw 18 having a right-hand wound. A binder in the form of clay auger 16 mix up, and then falls under the action of gravitational forces on the bottom of the device for mixing the material with a binder. The stirring mixture and the binder in the device 14 for mixing occurs due to the fact that the screws 17 and 18 have different winding. To create the required temperature in the device for mixing the material with a binder through the coil 21 is supplied to the coolant. Next formed a conglomerate of a mixture of aggregate, filler and binder from the device 14 for mixing is fed into the hopper 1, which falls in the interturn space of the conical screw 3. Moving the mixture along the body 2 from the hopper discharge opening is due to the rotation of the conical screw. During its movement along the body, the mixture is compacted and formed in the form of a briquette. When you exit the shell briquette using spring top plate 5 is moved to the scraper conveyor 4, which delivers it to below the receiving device.

Implementation of the invention allows the use of briquetting waste of animals and birds, and to use local resources in the form of easily accessible and safe for the environment materials, namely: waste animal waste, asbestos, clay, lime, gypsum, CE is UNT, the resin. These briquettes are used to produce heat.
