Description

Technical Field

[0001] The utility model belongs to the field of biogas slurry fertilizer treatment, and specifically relates to a biogas slurry fertilizer storage and filtration device. Background Art

[0002] Biogas slurry fertilizer refers to the liquid fertilizer produced during anaerobic fermentation, mainly composed of organic substances and nutrient elements. It is the liquid produced by fermenting raw materials such as animal feces and plant residues, rich in nutrients such as nitrogen, phosphorus, and potassium. Biogas slurry fertilizer can be used as a natural fertilizer to help improve soil and promote crop growth.

[0003] However, in order to improve its quality, effect, and safety during storage, a filtration device is used to filter the solid particles that are not fully decomposed in the biogas slurry fertilizer, such as fecal fibers and sediments, to prevent solid impurities from clogging the nozzle or pipeline during later fertilization, which may affect the fertilization effect and the operation of the equipment. When using a filtration device to filter biogas slurry fertilizer during storage, first, the biogas slurry fertilizer is transported to a storage tank, and the solid particles in the biogas slurry fertilizer are intercepted by a filter screen at the upper end inside the storage tank, and the liquid will pass through the filter screen and be stored in the inner cavity of the storage tank to achieve the filtration treatment of the biogas slurry fertilizer. However, in actual use, since the filter screen is in a fixed state, solid particles are likely to accumulate on the filter screen, causing the filter screen to clog and affecting the later filtration quality of the biogas slurry fertilizer.

[0004] In summary, the utility model provides a biogas slurry fertilizer storage and filtration device to solve the above problems. Summary of the Utility Model

[0024] As Figures 1-4As shown, the tank cover 12 is connected to the tank body 11 to seal the tank body 11, and the tank body 11 provides a space for storing biogas slurry fertilizer. The exhaust assembly 2 can exhaust the inside of the tank body 11 and purify the gas to prevent environmental pollution caused by the gas.

[0026] Referring to Figures 1-3 , this is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0027] In this embodiment, the top of the shaft rod 16 extends into the inner cavity of the sleeve block 19 and is movably connected to the inner cavity of the sleeve block 19. The connecting rod 13 and the scraping frame 14 both extend into the inner cavity of the centrifugal mesh cylinder 18, and the stirring blade 17 contacts the inner wall of the centrifugal mesh cylinder 18.

[0028] A liquid injection hopper 121 is connected to the top of the tank cover 12, and a sealing cover is movably connected to the top of the liquid injection hopper 121.

[0031] Embodiment 3

[0032] Referring to Figures 2-4, which is the third embodiment of the present utility model. This embodiment is based on the first two embodiments.

[0034] The exhaust assembly 2 includes an exhaust pipe 21. One end of the exhaust pipe 21 is provided with a filter cylinder 22. A honeycomb ceramic filter screen 23 is fixedly connected to the inner cavity of the filter cylinder 22. One end of the filter cylinder 22 communicates with a threaded cylinder 221.

[0035] One end of the exhaust pipe 21 communicates with the can lid 12, and a valve is communicated with the surface of the exhaust pipe 21. The other end of the exhaust pipe 21 is fixedly connected with a sealing ring 211, and one side of the sealing ring 211 contacts the filter cylinder 22.

[0036] As Figures 2-4 shown, the can lid 12 drives the connecting cylinder 122 to align with the can body 11, and the can lid 12 is rotated. The can lid 12 drives the connecting cylinder 122 to rotate. While the connecting cylinder 122 rotates, it will gradually enter the inner cavity of the can body 11, thereby realizing the connection between the can body 11 and the can lid 12 and closing the can body 11. By rotating the filter cylinder 22, the filter cylinder 22 drives the threaded cylinder 221 to rotate, so that the threaded cylinder 221 gradually enters the inner cavity of the exhaust pipe 21, realizing the connection between the exhaust pipe 21 and the filter cylinder 22.

The output shaft of the motor 15 drives the shaft rod 16 to rotate, and the shaft rod 16 can drive the sleeve block 19 and the centrifugal mesh cylinder 18 to rotate. While the centrifugal mesh cylinder 18 is rotating, it centrifugally filters the biogas slurry fertilizer, leaving solid particles inside the centrifugal mesh cylinder 18. At the same time, the scraping frame 14 continuously contacts the centrifugal mesh cylinder 18 and scrapes the solid particles, thereby preventing the solid particles from accumulating and blocking the centrifugal mesh cylinder 18, improving the efficiency and quality of filtration. The filtered biogas slurry fertilizer will flow to the lower end inside the tank body 11 for storage. During the storage process, the motor 15 drives the shaft rod 16 and the stirring blades 17 to move. While the stirring blades 17 are moving, they can drive the biogas slurry fertilizer to move, thereby keeping it in a flowing state, and further improving the storage quality and uniformity of the biogas slurry fertilizer. At the same time, the gas inside the tank body 11 can be discharged outward through the exhaust pipe 21. The gas will enter the inner cavity of the filter cylinder 22, and the honeycomb ceramic filter screen 23 inside the filter cylinder 22 removes the odor and some gas pollutants in the gas, and finally discharges them, effectively preventing the situation of gas polluting the external environment.
