Description

Technical Field

[0001] The invention relates to the technical field of organic fertilizer production and processing, and in particular to a livestock breeding excrement organic fertilizer mixing production device. Background Art

[0002] Fermenting livestock manure into organic fertilizer is an environmentally friendly and healthy practice that can reduce waste pollution to the environment while increasing the yield and quality of crops. After the fermented manure has cooled, it can be mixed evenly with other organic materials (such as sawdust, straw, etc.) and then made into organic fertilizer. The specific process is to add an appropriate amount of water to keep the mixture at a certain humidity. It is generally advisable to hold it in the hand and let it fall apart when it hits the ground. Then put the mixture into an organic fertilizer making machine to make organic fertilizer blocks or organic fertilizer powder.

[0003] At present, the mixing of feces and organic fertilizers mostly uses fermentation tanks with mixing and stirring functions. During the mixing process of feces and other organic materials, the temperature inside the fermentation tank can be controlled. When mixing feces and other materials, in order to better ferment the feces and improve the efficiency of organic fertilizers, it is sometimes necessary to mix nutritional additives and fungi into the mixture of feces and organic materials during the mixing process. At present, feces, organic materials and fungi are usually sent to the inside of the fermentation tank in the initial stage of mixing. During the mixed fermentation, sterile gas needs to be introduced into the inside of the fermentation tank, and fermentation will also produce a large amount of gas. The inside of the fermentation tank is in a higher pressure environment, which makes it inconvenient to introduce materials into the fermentation tank during the fermentation process, and it is inconvenient to regulate the fertilizer flora or nutrition during the mixing process.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figures 1 to 4, a mixed production equipment for organic fertilizer of animal husbandry manure, comprising a fermentation tank 1, a mixing mechanism, an exhaust mechanism, a feeding mechanism and a purification component. Compared with the method of mixing organic fertilizers in the fermentation tank 1 with a mixing and stirring mechanism in the prior art, the present invention not only stirs the materials through the mixing mechanism, but also extracts the excess gas in the fermentation tank 1 through a vacuum pump 201, reduces the air pressure in the fermentation tank 1, and facilitates the addition of materials.

The blower 6 is used to increase the impact force of the material entering, and the mixing effect of the material added in the middle and the original material is improved.

[0047] The mixing mechanism is used to mix the materials inside the fermentation tank 1. The mixing mechanism includes a stirring rod 101 and a stirring blade 102. The stirring rod 101 is rotatably arranged inside the fermentation tank 1, and the stirring blade 102 is arranged outside the stirring rod 101.

The vacuum pump 201 is arranged outside the fermentation tank 1, and the air inlet of the vacuum pump 201 is connected to the top of the fermentation tank 1. When feces and other organic materials are mixed, the feces fermentation will produce gas, and during the mixing process, it is sometimes necessary to add oxygen or other substances required for fermentation into the fermentation tank 1, which causes the pressure in the fermentation tank 1 to further increase. The gas in the fermentation tank 1 is extracted by the vacuum pump 201 to reduce the air pressure in the fermentation tank 1, thereby avoiding safety hazards caused by excessive air pressure in the fermentation tank 1, and at the same time avoiding the phenomenon that it is difficult to introduce new raw materials or gases into the fermentation tank 1 when the air pressure in the fermentation tank 1 is too high.

[0049] The feeding mechanism is used to add materials to the inside of the fermentation tank 1. The feeding mechanism includes a feeding cylinder 301, a piston 302, a raw material cylinder 303 and a gas adding pipe 304. The feeding cylinder 301 is arranged outside the fermentation tank 1.

The gas filling pipe 304 is connected to the external gas supply device, and the gas supply pipe 304 can be opened and closed by valve two. The external gas supply device transports oxygen or other gases required for fermentation to the inside of the raw material barrel 303. The bottom of the raw material barrel 303 can be squeezed by the movement of the piston 302 to send the raw materials or gas inside the raw material barrel 303 into the inside of the fermentation barrel.

[0050] The purification component is used to purify the extracted gas and assist in adding the material inside the raw material barrel 303 to the inside of the fermentation tank 1. The purification component includes a purification chamber 1 401, a combustion chamber 402, a purification chamber 2 403 and an adsorption chamber 404. The bottom of the purification chamber 1 401 is connected to the air outlet of the vacuum pump 201, the bottom of the combustion chamber 402 is connected to the top of the purification chamber 1 401, a burner 405 is arranged inside the combustion chamber 402, the bottom of the purification chamber 2 403 is connected to the top of the combustion chamber 402, the bottom of the adsorption chamber 404 is connected to the top of the purification chamber 2 403, an activated carbon adsorption plate 406 is arranged inside the adsorption chamber 404, and the adsorption chamber 404 is connected through a three-way valve. The air supply pipe 2 and the exhaust pipe 3 are connected, and the top of the feeding cylinder 301 is connected with the air inlet pipe 4 and the air outlet pipe 5 through a three-way valve. The air inlet pipe 4 is connected with the air supply pipe 2. The purification chamber 1 401 and the purification chamber 2 403 are both filled with purification liquid. The gas sucked out from the fermentation tank 1 by the vacuum pump 201 is sent into the purification chamber 1 401. The gas enters the purification chamber 1 401 from the bottom of the purification chamber 1. The gas enters the purification liquid and fully contacts and reacts with the purification liquid. The purification liquid deodorizes and sterilizes the gas. The preliminarily purified gas enters the combustion chamber 402. The burner 405 burns, sterilizes and removes impurities on the gas inside the combustion chamber 402, and then the gas enters At the bottom of the purification chamber 2 403, the gas enters the purification liquid for deodorization and sterilization, and finally the gas enters the adsorption chamber 404, and the odor and impurities in the gas are removed by the activated carbon adsorption plate 406. The adsorption chamber 404 is provided with a replacement port, and a replacement plate is provided at the replacement port. The activated carbon adsorption plate 406 is slidably set inside the replacement port. The activated carbon adsorption plate 406 can be replaced by regularly removing the replacement plate. A plurality of activated carbon adsorption plates 406 can be set inside the adsorption chamber 404. The upper activated carbon adsorption plate 406 is replaced first, and then the lower activated carbon adsorption plate 406 is placed on the top, and the new activated carbon adsorption plate 406 is installed at the bottom.

The air supply pipe 2 or the exhaust pipe 3 is connected to the adsorption chamber 404 through the three-way valve, and the purified gas is sent to the top of the feeding cylinder 301 through the air supply pipe 2. As the gas continues to enter, the pressure above the feeding cylinder 301 gradually increases, causing the piston 302 to descend, squeezing the raw materials or gas below the feeding cylinder 301 and sending it into the interior of the fermentation cylinder to mix with the original material. When no feeding is needed, the exhaust pipe 3 and the adsorption chamber 404 are connected, and the purified gas can be discharged to the outside.

[0051] In order to improve the efficiency of raw material entry, a blower 6 is also included. The air inlet of the blower 6 is connected to the air supply pipe 2, and the air outlet of the blower 6 is connected to the air inlet pipe 4. When adding materials to the inside of the fermentation tank 1, turning on the blower 6 can increase the speed of gas entering the feeding barrel 301, so that the pressure on the top of the feeding barrel 301 increases rapidly, and the movement of the piston 302 is accelerated, thereby increasing the speed of material entry.

[0052] It should be noted that after the material is added to the bottom of the feeding barrel 301, the piston 302 descends under the air supply of the vacuum pump 201 and the blower 6, and the material is delivered to the interior of the fermentation tank 1. During the feeding process, valves 1 and 2 are in a closed state to prevent the material from entering the gas pipe 304 or the feeding barrel 301. After the feeding is completed, the adsorption chamber 404 and the exhaust pipe 3 are connected through the three-way valve, and the purified gas no longer enters the feeding barrel 301. At the same time, the outlet pipe 5 and the feeding barrel 301 are connected through the three-way valve. The piston 302 moves upward under the action of the spring.

The spray pipe 7 is connected to the bottom of the feeding cylinder 301. A plurality of nozzles 8 are arranged on the spray pipe 7. The plurality of nozzles 8 have different directions, so that the materials can be sprayed in different directions when entering the fermentation cylinder. The sprayed materials and gases impact the original materials in the fermentation tank 1, thereby improving the mixing effect of the original materials and facilitating the mixing of the later added materials into the original materials.
