Abstract

The proposed utility model relates to the field of agriculture and can be used for processing and disposal of agricultural waste, in particular poultry manure to produce marketable products - high-quality fertilizers and / or feed additives. The objective of the proposed technical solution is to prevent the release of agricultural emissions - bird droppings - after it is dried into the atmosphere. The technical result that can be obtained is to increase the "yield" of a marketable product, thereby increasing the productivity of the process.

Description

The proposed utility model relates to the field of agriculture and can be used for processing and disposal of agricultural waste, in particular poultry manure to produce marketable products - high-quality fertilizers and / or feed additives.

Known (RF Patent No. 2181631 for Application No. 96109819/13 with priority dated 05/06/1996; publ. 09/10/1998, Bull. No. 25; MKI ⁶ CO 5 F 3/06). "Production line for processing agricultural waste." The well-known production line includes (Fig. 1): storage tank 1 for the initial waste of feeding complexes; conveyor - 2; a furnace for receiving heat carrier gas - 3: a drying chamber 4; the disintegrator - 5, which is a rotating shaft with chain links distributed along its length; cyclone 6; fan 7; conveyor 8 for returning the dust caught by the cyclone to the “head” of the process; a mixer 9 for mixing the initial wet waste with dust trapped in the cyclone; a conveyor 10 for loading wet material into the drying chamber; capacity - 11 for the collection of a commercial product.

This technical solution allows to obtain high-quality organic fertilizer from non-utilized production waste. A disadvantage of the known production line is significant emissions into the atmosphere with exhaust gases - after the cyclone - the dust fraction of the dried (heat-treated) agro-industrial waste - bird droppings.

Of the known analogues, the closest in technical essence, the set of essential features and the technical result achieved, is the well-known technical solution (RF Certificate for Utility Model No. 23730 by application No. 20011118861/20 with priority dated July 6, 2001; Zaregistr. And publ. 20.07. 2001, Bull. No. 20; MKI ⁷ A 23 K 1/22) - “Installation for drying pasty materials” (including bird droppings) - adopted as a prototype.

The hardware-technological line for processing agricultural waste (“Installation ...” according to the prototype includes (Fig. 2): a furnace 1, a storage tank 2, a conveyor 3, a feeding system for litter 4, a stationary drying chamber 5, a cyclone 6, a fan 7, a container for collecting the finished product 8 and a precipitating self-unloading chamber 9.

"Installation ..." according to the prototype works as follows: the initial wet litter is loaded into a storage tank 2, from which, with a certain flow rate, it is fed by a conveyor 3 to a distribution device 4 and through it to the drying chamber 5. At the same time, gas is supplied to the drying chamber carrier from the furnace 1. Dried droppings in the form of particles of various sizes and masses from the drying chamber 5 sequentially

first enters the precipitation self-unloading chamber 9 of the finished product - heat-treated, dried agro-industrial waste (bird droppings) is collected in a container 8.

A well-known technical solution - the prototype provides high-quality fertilizers with high consumption properties and increased agrochemical characteristics.

The disadvantage of the technical solution for the prototype is, as shown by the results of the installation over several years (more precisely - the factory for processing poultry manure in the city of Solikamsk, Perm region), the incomplete capture of a marketable product - dried poultry manure in a sedimentation chamber and cyclone. The consequence of this is: loss of commercial products with exhaust gases (dust and gas and aerosol mixtures) and environmental pollution by dried bird droppings.

The objective of the proposed technical solution is to prevent the release of agricultural waste - bird droppings - after it is dried into the atmosphere. The technical result that can be obtained in this case is to increase the “yield” of a marketable product, thereby increasing the productivity of the process.

The problem is solved and the technical result is achieved by the proposed Instrumentation technological line, which includes the storage capacity of the initial wet agricultural waste, in particular poultry manure, conveyor, firebox, drying chamber and a precipitation self-unloading chamber, cyclone, fan, finished product capacity. A feature of the claimed utility model is that after the cyclone a water-irrigated absorber with a fluidized nozzle is additionally installed, the discharge formed in the suspension absorber is directed to the circulation tank and to the storage tank for the initial agro-industrial waste.

This feature of the utility model, as shown by tests, ceteris paribus makes it possible to capture dust fractions of dried agro-industrial waste - bird droppings from exhaust gases (dust-gas mixture) and thereby prevents environmental pollution.

The analysis of the prior art in relation to the set of essential features of the proposed technical solution shows that the proposal "Hardware technological line" meets the criterion of "novelty."

Checking the conformity of the claimed technical solution to the requirement of "inventive step" in relation to the set of essential features indicates that the proposed design of the technological line does not follow explicitly from the prior art for specialists (see, for example, V. Malofeev, Non-waste production technology in poultry farming . - M.: Agrokhimizdat, 1986; V. Malofeev. Thermal drying of the litter // Poultry Production Journal, 1993, No. 2. P.17-19).

Figure 3 shows the proposed "Hardware technological line", which includes: storage capacity (1),

a furnace (2), a conveyor (3), a loading device (4), a drying chamber (5), a self-unloading sedimentation chamber (6), a cyclone (7), a water-irrigated absorber with a fluidized nozzle (8), a circulation tank (9), a tank finished product (10).

Implementation of the proposed "Hardware technological line for processing agricultural waste" is as follows.

The initial wet (70-90%) agro-industrial waste, for example, bird droppings, is loaded into a storage tank (1), from where it is fed through a furnace (3) and a loading device in a dispersed form into a chamber made in the form of “ dryer pipes. " In the drying chamber, heat-treated floor wastes are subjected to dehydration to a residual moisture content of 5-15% by the influence of flue gases of the furnace (3). the dust-gas mixture sequentially passes through a precipitation self-unloading chamber (5); cyclone (6) and is supplied for final cleaning and neutralization in a water-irrigated absorber with a fluidized nozzle (7), the suspension of which is sent to a circulation tank (8) connected to a storage tank (9). Finished product - heat-treated and dried agro-industrial waste is collected (from chamber 5 and cyclone 6) in a container for the finished product (9), then packaged and sold as environmentally friendly fertilizer and / or as a feed additive to replace and / or prepare feed.

Claims (1)

Equipment and technological line for processing agricultural waste, including storage tank, conveyor, firebox, drying chamber, self-unloading sedimentation chamber, cyclone, fan, finished product tank, characterized in that it additionally contains a water-irrigated absorber with a fluidized nozzle after the cyclone, discharge of the suspension from which is sent to the circulation tank and the storage tank for the source of agricultural waste.
