Description

The invention relates to agriculture, in particular to devices for processing manure.

Known installation for methane digestion of manure (AS No. 1549496, A 01 3/00, 1990, bull. No. 40), containing a receiving tank in communication with a cylindrical reactor having a gas cap, a biogas extraction device, a hydrodynamic device mixing the fermented mass. The unloading capacity of the installation is made in the form of a hydraulic shutter in communication with the receiving tank and the reactor. Installation is complicated, therefore unreliable in operation.

Closest to the proposed invention is a fermenter (magazine "Home, Garden, City", 2001, No. 4, p. 18), containing a tank with a cap installed with a water seal and equipped with a pipe for gas removal, pressure gauge, biomass heater.

The disadvantages of the described design are the high energy consumption during unloading of biomass, the fragility of the mass heater due to its presence in an aggressive environment, the difficulty of cleaning containers from solid inclusions, and the lack of devices for mixing the mass.

The objective of the invention is to reduce energy costs during unloading of biomass, increasing the service life of the installation.

The problem is solved in that in a plant for processing manure containing a receiving tank, a gas cap, a water seal, a heating and gas extraction device, a pressure gauge, a receiving tank is lined with a cover with a rigidly fixed upper edge made of an elastic waterproof material with a reinforced bottom connected with a lifting mechanism and resting on a grate, under which there is a heating device in a water jacket, and the hydro-sealant is equipped with an unloading pipe, the end of which is above the discharge level th site.

The invention is illustrated by drawings, where figure 1 is a General view of the installation (before unloading biomass), section AA; figure 2 is the same, top view, section bb; figure 3 - General view of the installation (after unloading the biomass), section AA.

A biogas plant for processing manure includes a cylindrical receiving tank 1, above which a gas cap 3 in the form of a hemisphere is equipped through a ring hydro-sealant 2, equipped with a manometer 4 and a gas sampling device 5 with a tap. The sealant 2 is equipped with an unloading pipe 6 with a valve 7, the end of which is above the level of the unloading platform 8 for supplying a vehicle hopper under it. The receiving container 1 is lined with a cover 9, the upper edge of which is rigidly fixed to the hydro-sealant 2. The cover is made of an elastic waterproof material, for example, rubberized tarpaulin, with a reinforced bottom 10. The bottom 10 by means of an attached twisted cable 11 passing through the gland 12 installed in the cap 3, is connected with a lifting mechanism 13 located above the receiving tank 1 on the beam 14. The bottom 10 of the cover rests on a grid 15, under which there is a biomass heating device 16 located in the water jacket 17. Above the lattice 15 in the wall of the receiving tank 1 has a through channel 18 for communication with the atmosphere.

ее объема, при этом чехол 9 защищает устройство подогрева и стенки емкости от его агрессивного действия. Затем над емкостью 1 устанавливают колпак 3, герметизируют его с помощью гидрогерметизатора 2, заполненного водой. Трос 11 пропускают через сальник 12, установленный в колпаке 3 и соединяют с тросом подъемного механизма 13. Включают устройство подогрева 15 для ускорения метанового сбраживания навоза. По манометру 4 следят за давлением газа под колпаком 3. Периодически производят перемешивание биомассы путем 2-3-кратного частичного подъема чехла с массой до верха приемной емкости 1, открывают кран устройства отбора газа 5 для его сбора в накопитель (не показан). После окончания процесса сбраживания навоза снимают колпак 3 и производят выгрузку биомассы из емкости 1, для чего трос 11 цепляют к тросу подъемного механизма 12 и с его помощью поднимают дно 10. Скорость подъема должна быть такой, чтобы не произошло переливания биомассы из кольцевого гидрогерметизатора. Таким образом вся биомасса выливается из емкости, попадает в кольцевой гидрогерметизатор 2 и по трубопроводу 6 - в бункер транспортного средства (не показан). После заполнения бункера задвижку 7 выгрузного трубопровода 6 закрывают и подгоняют под загрузку следующее транспортное средство. Полная выгрузка биомассы будет произведена при нахождении дна 10 чехла в крайнем верхнем положении. Затем подъемным механизмом дно опускают вниз и установка готова для следующего цикла работы.Installation works as follows. Pour water into the receiving container 1, creating a water jacket 17 for the heating device 16, to the level of the lattice 15. Then, the container 1 is lined with a cover 9, the cable 11 is fixed to the reinforced bottom 10 of it, its other end is fixed on the upper edge of the container 1. The manure is loaded in the receiving tank on

its volume, while the cover 9 protects the heating device and the walls of the tank from its aggressive action. Then, a cap 3 is installed over the container 1, it is sealed with a hydro-sealant 2 filled with water. The cable 11 is passed through an oil seal 12 installed in the cap 3 and connected to the cable of the lifting mechanism 13. The heating device 15 is turned on to accelerate the methane digestion of manure. Using a manometer 4, monitor the gas pressure under the cap 3. Periodically mix the biomass by 2-3-fold partial lifting of the cover with the mass to the top of the receiving tank 1, open the tap of the gas sampling device 5 to collect it into a reservoir (not shown). After the end of the manure fermentation process, the cap 3 is removed and the biomass is unloaded from the tank 1, for which the cable 11 is hooked to the cable of the lifting mechanism 12 and the bottom 10 is lifted with it. Thus, the entire biomass is poured out of the tank, enters the annular hydrometer 2 and through the pipeline 6 - into the hopper of the vehicle (not shown). After filling the hopper, the valve 7 of the discharge pipe 6 is closed and the next vehicle is adjusted for loading. A complete unloading of biomass will be made when the bottom 10 of the cover is in its highest position. Then, with a lifting mechanism, the bottom is lowered down and the installation is ready for the next cycle of work.
