Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a manure treatment system for pig farms. Background Art

[0002] The manure treatment system of pig farms is an indispensable part of the sustainable development of modern animal husbandry. It is directly related to environmental protection, resource recycling, and the economic benefits and social image of the breeding industry. Its function is to effectively collect, classify and utilize the large amount of feces and urine produced by pig farms, reduce environmental pollution and transform them into valuable by-products. Generally speaking, pig farm manure usually contains high concentrations of organic matter, nitrogen, phosphorus and microorganisms. If it is discharged directly without proper treatment, it will cause serious pollution to the environment.

[0003] At present, when treating pig farm manure, pig farm manure is usually collected first, and then the dry and wet parts of the manure are separated. The separated solid part is dried or mixed with straw, rice husks, etc. and then composted. Through the action of microorganisms, it is converted into high-quality organic fertilizer for farmland fertilization to achieve nutrient recycling. As for the separated liquid part, it can be fermented into biogas through anaerobic digestion process, and the organic matter therein is used to produce biogas (the main component is methane), which not only solves the manure treatment problem, but also obtains clean energy. However, nowadays, when using the separated liquid part for biogas fermentation, most of them are only in When natural conditions permit, the temperature in the digester can be increased by increasing the sunshine time and intensity, thereby promoting microbial activity and accelerating biogas fermentation in the liquid part. However, in actual operation, this method still takes a long time for the liquid part to undergo biogas fermentation, and the efficiency is low. Although the biogas fermentation in the liquid part can be accelerated by artificially adding carbon sources (such as straw, corn stalks) or nitrogen sources (such as urea) to the liquid part, the liquid part is generally a sealed environment during biogas fermentation. Artificially adding carbon sources or nitrogen sources is not only inconvenient to operate, but also easy to cause biogas leakage, thereby causing harm to the environment and the surrounding human bodies.

[0048] See also Figure 19-21 As shown, it also includes a flushing mechanism, which includes a driving motor 37, a screw rod II 38, a nozzle II 39, a connecting block 40, a double-layer hollow winding drum 41, a spring 42 and a connecting pipe I 43; the driving motor 37 is installed inside the treatment tank 1; the screw rod II 38 is connected to the output shaft of the driving motor 37; the nozzle II 39 is threadedly connected to the screw rod II 38, and the nozzle II 39 is slidably connected to the treatment tank 1, so that when the driving motor 37 drives the screw rod II 38 to rotate, the nozzle II 39 can be driven to move, and the nozzle II 39 is located directly below the rotating column 4, and the nozzle on the nozzle II 39 The mouth faces the rotating column 4 so that the nozzle of the nozzle II 39 can spray water toward the rotating column 4 for flushing; two connecting blocks 40 are distributed up and down and are both connected to the inner wall of the treatment pool 1; the double-layer hollow winding drum 41 is rotatably connected between the two connecting blocks 40, and the bottom end of the double-layer hollow winding drum 41 is connected to the upper port of the electric three-way valve 28; the two ends of the clockwork 42 are respectively connected to the bottom end of the double-layer hollow winding drum 41 and the lower side of the connecting block 40; two connecting pipes I 43 are wound on the double-layer hollow winding drum 41, and the two ends of the connecting pipe I 43 are respectively connected to the double-layer hollow winding drum 41 and the nozzle II 39.

[0049] When in use, the electric push rod II 33 can be used to drive the connecting plate 34 to move away from each other, thereby driving the T-block 35 to move away from each other, and then the T-block 35 enters the movable groove 341 in the rotating column 4, and then the electric push rod I 31 drives the rack 32 to move to the right (the next time it is used, the rack 32 is driven to move to the left, and this can be repeated left and right), so that the rack 32 drives the rotating shaft 3 and the T-block 35 to rotate 180 degrees. At this time, if the pig does not step on the rotating column 4, the rotating shaft 3 uses the torsion spring 36 to drive the rotating column 4 to rotate 180 degrees synchronously. At this time, if the pig steps on the rotating column 4, the rotating shaft 3 does not need to use the torsion spring 36 to drive the rotating column 4 at that place to rotate synchronously The torsion spring 36 is deformed and the pig is driven away from the rotating column 4. When the pig leaves the rotating column 4, the torsion spring 36 returns to its original state, and the torsion spring 36 drives the rotating column 4 to rotate 180 degrees. Then, the connecting plate 34 is driven to move to the side close to each other and reset through the electric push rod II 33, thereby driving the T-block 35 to move to the side close to each other and reset, and then the T-block 35 leaves the movable groove 341 in the rotating column 4, so that the T-block 35 locks the rotating column 4 (because the rack 32 clamps the rotating shaft 3, the rotating shaft 3 cannot rotate, so that the T-block 35 and the rotating column 4 cannot rotate), to prevent the rotating column 4 from rotating and affecting the pig's entry. The electric three-way valve 28 is then controlled to connect the lower port with the upper port, and the filtered water in the filtered water storage space 53 is pumped into the electric three-way valve 28, the double-layer hollow winding drum 41, the connecting pipe I 43 and the nozzle II 39 through the water pump 27, so that the nozzle of the nozzle II 39 sprays the filtered water on the bottom and side of the rotating column 4, thereby flushing the bottom and side of the rotating column 4, and then the driving motor 37 drives the screw rod II 38 to intermittently rotate forward and reverse, so that the nozzle II 39 moves back and forth, so that the filtered water sprayed by the nozzle II 39 flushes the bottom and side of the entire rotating column 4, which is not only convenient for the breeding personnel to flush the bottom and side of the rotating column 4 Wash, and by setting the nozzle on the nozzle pipe II 39 to face the rotating column 4, it is possible to avoid a large amount of filtered water spraying onto the pigs, so as to prevent the pigs from catching a cold and getting sick. During this period, when the nozzle pipe II 39 moves back and forth, the nozzle pipe II 39 will pull or loosen the connecting pipe I 43. When the nozzle pipe II 39 pulls the connecting pipe I 43, the connecting pipe I 43 will pull the double-layer hollow winding reel 41 to rotate, and the spring 42 will be deformed. When the nozzle pipe II 39 loosens the connecting pipe I 43, the spring 42 returns to its original state, and the spring 42 drives the double-layer hollow winding reel 41 to reverse and reset, so that the double-layer hollow winding reel 41 reels the connecting pipe I 43, so as to prevent the connecting pipe I 43 from being scattered all over the ground.
