Abstract

Usage: in agricultural machinery, in particular in devices for disinfecting manure with liquid ammonia. SUMMARY OF THE INVENTION: the device comprises a manure conduit (|| flow). The ammonia dispenser 3 is equipped with an ammonia supply regulator and is connected to a storage tank 6. The flow swirl is made in the form of a hollow perforated screw blade 7, which is mounted on the pipe 8 The ammonia supply regulator is made in the form of a chamber 9, which is divided into cavities 11 and 12 by means of an elastic-elastic diaphragm 10. An excess pressure is created in the manure pipe by the pump, which bends the diaphragm 10 and expels the working fluid from the floor spine 12 into the cavity 17. When moving, the piston 15 extends the rod 14, which acts on the working body of the dispenser 3. Ammonia enters the pipe 8 through the pipe 20 and is fed into the thickness of the manure through the perforation of the blade 7. An increase in the flow of manure increases the amount of liquid displaced from cavity 12 into the cavity 17 of the hydraulic cylinder. 2 ill., j cl C

The invention relates to agriculture, in particular to the processing of manure.

The purpose of the invention is to increase operational reliability and also simplify the design.

Figure 1 is a perspective view of a device for disinfecting manure with liquid ammonia; figure 2 - node I in figure 1.

The device contains a pressure manure. An outlet 1 with a flow swirl 2 placed therein, an ammonia dispenser 3, connected to a drive in the form of a hydraulic cylinder 4, equipped with a regulator 5 for supplying ammonia and connected to a tank 6 for it

neni. The flow swirl 2 in the form of a hollow perforated propeller blade 7, mounted on a pipe 8 and

in communication with ammonia storage tank 6 via dispenser 3.

The ammonia supply controller 5 is made in the form of a chamber 9 installed in the wall of the manure pipe 1 and divided by two transverse elastomeric diaphragm 10 into two cavities 11 and 12. In this case, the cavity 11 is in communication with the manure pipe 1 through the window 13, and the cavity 12 is connected to the hydraulic cylinder 4. The hydraulic cylinder 4 interacts with the dispenser 3 by means of a rod 14 mounted on a piston 15 provided with a return spring 16. The cavity 17 of the hydraulic cylinder 4 is connected by a pipe 18 to the cavity 1-2 of the chamber 9. The cavities 17 and 12 are filled with a working fluid.

The dispenser 3 and the ammonia storage tank 6 are communicated via line 19. The ammonia from the dispenser 3 is fed into the manure line 1 via line 20.

One end of the manure pipe, .1, is equipped with a pump 21, the suction pipe of which is lowered into the collector 22, and the other end of the manure pipe is placed in the manure storage 23.

The device operates as follows.

When pump 21 feeds manure from the manure collector 22, excessive pressure is created in the manure pipe 1, which bends the diaphragm 10 and displaces the working fluid from the cavity 12 through the pipe 18 to the cavity 17. During its movement, the piston 15 extends the rod 14 and compresses the spring 16, The rod 14 acts on the working body of the dispenser 3 and the latter feeds ammonia through a pipe 20 into the pipe 8, from where 1mmia through the perforation of the blade 7 is fed about the thickness of the manure. Since manure is intensively mixed during the passage between the turns of the blade 7, ammonia is evenly distributed over the entire cross section of the manure pipe.

With an increase in the manure flow rate, the pressure in it increases correspondingly, which increases the amount of displaced working fluid from the cavity 12 into the cavity 17 of the hydraulic cylinder. In this case, the rod 14 extends to a greater extent, as a result of which the dispenser 3 increases the supply of ammonia to the manure pipe 1.

When the manure pressure in the manure pipe decreases, the spring 16 moves the piston 15 to the right, retracts the rod 14 and

displaces the working fluid into the cavity 12, which leads to the bending of the diaphragm 10 in the other direction and squeezing the manure from the cavity 11 into the cavity of the manure pipe 1. Thus, the ammonia flow is automatically adjusted depending on the manure flow.

The technical and economic efficiency of the proposed device is to reduce its cost to 10%. At the same time, the reliability of the operation of the device is increased several times, since there are no rotating units in an aggressive environment, therefore, clogging of rubbing pairs of sediments and jamming are excluded.
