- unloading device - for unloading dry bird droppings (SPP);

zooMC 05 F 3/06

-filling machine;

- biofilter system - for cleaning off-volatile, toxic and foul smelling waste (from the drying drum); their gases.

The disadvantages of the known production line and its modifications are:

- the complexity of the design of the main node of the note line - a drying drum;

-the need for special measures - the manufacture and inclusion in the production line of special biofilters for the purification of exhaust gases;

- unsatisfactory: the quality and consumer properties of the finished product obtained, in particular, on the well-known production line receive SPP in the form of an inhomogeneous mass of irregular shape: from 1 to 10 cm

Of the known analogues, the closest in technical essence and the achieved result to the proposed technical solution is the well-known (A. A. Kiva, Yu.I. Sukharev, V. M. Lukyanov. Machines and equipment for poultry farming. Reference book. - M.: Agropromizdat. - 1987. - S. 185) production line for the processing of wet materials - bird litter PROTOTYPE.

The prototype production line includes:

-Cumulative capacity for the initial wet bird droppings;

-conveyor;

-the furnace (for burning natural gas, fuel oil, diesel fuel) to produce a coolant gas;

- a drying chamber, which is a rotating drying drum;

-crusher for crushing and grinding large lumps of dried SPP;

- a conveyor for returning the SGS whined by the cyclone to the "head of the process;"

-mixer for mixing the initial wet (raw) bird droppings with SGS dust trapped in a cyclone;

- a conveyor for loading manure (a mixture of crude manure and dust SPP) into the drying drum;

-Capacity for the collection of marketable products;

-filling machine.

The prototype production line has the following main disadvantages:

- Comparatively low quality and consumer properties of the finished product obtained - SPP. The known production line provides SPP in the form of particles, pieces, agglomerates of irregular shape; various: size (1-10 mm), composition and humidity; at the same time, own quality losses are observed due to burning of agglomerates, dust extraction, boiling of the initial wet litter on the walls of the drum.

- Significant energy and labor costs for the manufacture, maintenance and operation of the drying chamber, which in turn is due to the peculiarity of the design of the drying chamber and its structural units, we adjoin them; they are included; they are part of the production line.

This disadvantage is associated with the fact that the drying chamber, which is part of the known production line, is a rotating drying drum, which in turn imposes stringent requirements on sealing the docking assemblies of rotating and fixed parts of the drum and other nodes of the production line; in addition, it requires significant energy consumption for the rotation of the drum; in the process of drying manure in a rotating drum, particles of manure are rolled into rather large aggregates and agglomerates (10-50 mm). This, in turn, necessitates the inclusion of special devices in the production line, in particular, “cro3 //.cf

shitel - for crushing and grinding large aggregates and agglomerates, which in turn also complicates the process. And finally, it should be noted that in case of forced, emergency or preventive stops of the production line, the process of cleaning the drying drum from adhering, burnt litter particles requires a lot of labor (including manual labor) and leads to disruption of the rhythm of the production line as a whole.

The tasks solved by the proposed utility model "Production line for the processing of wet materials, are:

-improving the quality and consumer properties of products;

-increasing the reliability of the production line operation, reducing energy and labor costs, simplifying the technology of processing wet material in general.

The problem is solved by the proposed "Production line for the processing of wet materials, which includes a number of interconnected apparatuses, devices and structural elements. The essence of the claimed technical solution is illustrated in the figure. According to the proposed utility model, the production line includes:

-granulator material made in the form of an extruder - 14

transporter - 15

capacity for the collection of marketable products - 16

-filling machine - 17

Soup1; The following structural elements, forms of their execution and their mutual arrangement among themselves are the natural distinguishing features of the claimed “Production line for processing wet materials”:

-between the storage tank and the conveyor, a humidifier of the source material is additionally installed;

-after the feed hopper, a spray of moistened material is installed;

-after cyclones installed irrigated scrubber;

storage capacity - 1, from where - to the humidifier of the source material - 2; at the same time, part of the pulp enters the humidifier from the irrigated scrubber - 10; in the humidifier, the raw material and pulp are mixed (for example with “screws”), as a result of which the material obtained acquires the required moisture and, accordingly, a consistency suitable for subsequent processing. The material thus prepared by the conveyor - 3 is sent to the loading hopper - 4, from where it is fed through the sprayer - 5 to the stationary drying chamber - 6; at the same time, a heat carrier gas stream (from burning fuel oil, diesel fuel, natural gas) is supplied from the furnace - 7. In the drying chamber, heat treatment and disinfection of the starting material, combustion of volatile organic matter, substances evaporating from the starting material, and, ultimately, partial dehydration of the starting material (for example, to a residual moisture content of 20-25%) takes place. A dust-gas mixture (aerosol, which is particles of dried starting material distributed in an environment consisting of air, carbon dioxide and water vapor), is then sent to a cyclone or, mainly, to a system of two series-connected cyclones - 8. In two cyclones, capture, as tests have shown, 95-97% of the obtained dried material. This dried material from cyclones is discharged into subcyclone bins - And from where it is then discharged to a mixer - 12. A dust-gas mixture containing 3-5% (of the total mass of the litter coming to the processing), passing through the cyclones, then enters the irrigated (for example, water or reverse pulp) scrubber - 10, in which the exhaust gases are cleaned from the dust fraction of the litter that has passed through the cyclone. The required exhaust gas is carried out by fan 9. A part of the pulp formed in the irrigated scrubber enters the mixer - 12 (simultaneously with the supply of dried manure from the cyclone bunkers). The mixer mixes the dried material and pulp. If it is necessary to expand the range of manufactured products, a certain amount of mineral or organic additives (oxide and / or hydroxide of calcium, magnesium, potassium chloride, magnesium, etc.; or grass meal, various components for the preparation of compound feeds, is also supplied to the mixer from dispenser 13. P.).

From the mixer - 12, a carefully mixed mixture of the required consistency is sent (for example, by a screw feeder) to the granulator - 14, made in the form of an extruder with the size of the dies (holes), for example, 3-5 mm. Granular material conveyor - 15 is sent to the tank for collecting commodity products - 16, and from it to the filling machine 17.
