RU204752U1 - BIOREACTOR-DISINFECTOR OF LOWER MANURE AND LITTER - Google Patents

Abstract

The bioreactor-disinfectant of litter manure and manure refers to agriculture and can be used for disinfection and processing of litter manure and poultry manure into an environmentally friendly organic fertilizer. The bioreactor-disinfectant of continuous action consists of a cylindrical drum equipped with an aeration system for organic matter, there is a loading belt conveyor with an ultraviolet irradiator of organic matter. There are loading and unloading ports on opposite sides of the cylindrical drum. An auger is installed inside the drum, which mixes the organic mass and transports the finished product to the unloading window. A useful model will allow you to get environmentally friendly organic fertilizer.

Description

The bioreactor-disinfectant of bedding manure and droppings can be used to destroy fungal colonies, pathogenic bacteria and helminths in the preparation of organic fertilizers.

A biofermenter for the conversion of organic waste of continuous operation consists of a stationary cylindrical body. The body has thermal insulation, inside the body there is a helical surface rigidly connected to the shaft resting on bearings. The shaft is mated with a variable drive. In the upper part of the body there is a loading window, above which a screw conveyor is installed. At the opposite end of the housing, in its lower part, an unloading window is provided, which is coupled with the unloading auger. An outside air supply duct is installed behind the unloading window, which is connected to the inner space of the housing. At the end of the screw surface, a horizontal scraper plate is installed above the unloading window, rigidly connected to the screw surface. The first turn of the helical surface has a pitch equal to the diameter of the shell shell with the formation of a receiving chamber under the loading window, the subsequent helical surface turns are equal to the radius of the shell shell of the bioreactor (Patent for utility model No. 146604).

The disadvantages of this model are:

- the loading screw conveyor compacts the organic mass - this leads to an anaerobic process;

- loaded organic mass into the bioreactor is not sufficiently disinfected.

The purpose of the utility model is to improve the process of disinfection of bedding manure and dung during the preparation of organic fertilizers.

This goal is achieved by installing an ultraviolet radiation source in the area of loading bedding manure or dung into the biofermenter.

Irradiation with an ultraviolet source of bedding manure or dung in the loading area destroys pathogenic bacteria, fungal microbiota and helminths. The resulting organic fertilizer is environmentally friendly and of high quality.

The essence of the proposed utility model is illustrated by Figure 1.

The bioreactor-disinfectant of bedding manure, chicken manure consists of a stationary cylindrical body 1. The body 1 has thermal insulation 2, inside the body 1 there is a helical surface 3, rigidly connected to the shaft 4, resting on bearings 5. The shaft 4 is mated with an adjustable drive 6. In the upper part of the housing 1 has a loading window 7, above which a belt conveyor 8 is installed, above which ultraviolet radiation sources 9 are installed, connected to the power unit 10. At the opposite end of the housing 1, in its lower part, an unloading window 11 is provided, which is coupled with the unloading auger 12. Behind the loading window 7, there is an external air supply duct 13 connected to the interior space of the housing 1. At the opposite end of the housing 1, an exhaust duct 14 is installed, also connected to the interior space of the housing 1. At the end of the screw surface 3 above the discharge window 11, a horizontal scraper plate is installed 15, hard with connected to the screw surface 3.

The bioreactor-disinfectant of bedding manure and manure for the preparation of organic fertilizer works as follows: bedding manure or chicken manure 16, irradiated with ultraviolet radiation sources 9, installed above the belt conveyor 8, through the loading window 7 is loaded into the receiving chamber 17. With the start of loading the receiving chamber 17 the system for supplying external air through the air duct 13 is switched on. Microbiological processes begin to develop in the organic mass loaded into the biofermenter, and the screw surface 3 slowly moves the organic mass in the axial direction. In the process of mixing, the organic mass is saturated with air and the intensification of microbiological processes takes place in it. When the organic matter matures, the unloading auger 12 is turned on and the finished organic fertilizer is unloaded from the bioreactor.

Claims (1)
