[0030] The present invention is further described below in conjunction with the accompanying drawings.

[0031] Example 1

In the process of discharging the biogas slurry into the tank body 7, the hose 3 will swing by itself. Through the circulation of the biogas slurry and the swing of the hose 3, the biogas slurry in the tank body 7 is fully stirred. A slag discharge pipe 5 is symmetrically fixedly installed at the bottom end of the tank body 7, an exhaust pipe 2 is fixedly installed on the top of the outer ring of the tank body 7, and the exhaust pipe 2 is located above the water inlet pipe 4.

[0033] The length of the hose 3 is equal to the internal radius of the tank body 7. One-way valves are installed on the slag discharge pipe 5, the water inlet pipe 4 and the drain pipe 6. The exhaust pipe 2 is connected to the inside of the tank body 7. The vacuum filter 1 is connected to the top of the tank body 7 through a pipe. The internal bottom end of the tank body 7 is conical.

[0034] The working principle of Example 1 is as follows: when in use, the drainage pipe 6 is connected to the first slurry pump outside, and the other end of the first slurry pump is connected to the end of the water inlet pipe 4 located outside the tank body 7, so that the biogas inside the tank body 7 can be circulated, and the hose is set so that the biogas in the tank body 7 is continuously disturbed during the circulation process, so as to fully achieve stirring. At the same time, when the vacuum filter 1 is started, the inside of the tank body 7 can be placed in a vacuum state, which is conducive to the fermentation of the substances inside the tank body 7. At the same time, through the setting of the exhaust pipe 2, the biogas generated in the upper layer of the tank body 7 can be easily discharged for use. A slag discharge pipe 5 is installed at the bottom end of the tank body 7, and the slag discharge pipe 5 can be opened so that the residual substances inside the tank body 7 can be discharged from the inside of the tank body 7 Discharge, at the same time, the drain pipe 6, the water inlet pipe 4 and the first slurry pump form a biogas circulation, and the hose 3 is swung at the bottom end of the tank body 7 under the pressure of the first slurry pump, so as to stir the biogas formed by the biogas residue and liquid. The device is equipped with a one-way valve on the water inlet pipe 4, the slag discharge pipe 5 and the drain pipe 6 to prevent the biogas from flowing back. At the same time, through the setting of the bacterial strain adding nozzle 39, the bacterial strain can be added to the inside of the tank body 7, so as to improve the efficiency and quality of biogas production. When the device is in use, the first slurry pump is connected to the drain pipe 6, and the slurry pump is equipped with a timer, which can be started at regular intervals. A second slurry pump is also provided outside the slag discharge pipe 5, which is used to pump the fermented biogas in the tank body 7 to the filter press for solid-liquid separation.

[0038] like Figure 4The guide component 9 includes a synchronous mixing device 15, a synchronous device 16, a displacement device 17 and an alignment device 18. The alignment device 18 is symmetrically fixedly installed on the outer ring of the guide component 9.

[0041] like Figure 7 and Figure 8The displacement device 17 includes a discharge hole 27, a sealing plate 28, a receiving cavity 29, an L-shaped connecting bracket 30, a third gear 31, a first rack 32, a key 33, a return spring 34 and a feed push plate 35. The sealing plate 28 is fixedly mounted at one end of the receiving cavity 29, the return spring 34 is symmetrically fixedly mounted at the other end of the receiving cavity 29, the third gear 31 is rotatably mounted on both sides of the receiving cavity 29 near the return spring 34, the key 33 is symmetrically fixedly mounted at the bottom end of the receiving cavity 29, the feed push plate 35 is fixedly mounted between the two L-shaped connecting brackets 30, and the L-shaped connecting bracket 30 is slidably inserted into the receiving cavity 29. Connected to the inner top of the receiving cavity 29, the first rack 32 is fixedly mounted on the bottom end of the L-shaped connecting bracket 30, and the discharge hole 27 is symmetrically opened at the inner bottom end of the receiving cavity 29 near the sealing plate 28. The alignment device 18 includes a transmission cylinder 36, a second rack 37 and a guide cavity 38. The guide cavity 38 is fixedly mounted at the bottom end of the transmission cylinder 36, and the second rack 37 is fixedly mounted on both sides of the inside of the guide cavity 38. When the receiving cavity 29 is located inside the guide cavity 38, the discharge hole 27 can be closed by the guide cavity 38, so that the quicklime powder inside the receiving cavity 29 can be prevented from falling prematurely.

[0042] The driving motor 14 is fixedly mounted at the top center of the guide component 9, the lower edge bracket 19 is symmetrically fixedly mounted at the inner top of the guide component 9, the second bevel gear 20 is meshed with the first bevel gear 11, the connecting rod 22 is symmetrically fixedly mounted at the inner top of the guide component 9 near the alignment device 18, the top of the connecting vertical frame 23 is connected to the bottom end of the sealing plate 28, the end of the return spring 34 away from the sealing plate 28 is connected to one end of the guide cavity 38, the tooth distribution angle of the first gear 13 is 180°, the bottom end of the stirring frame 21 and the top end of the stirring blade 12 are spaced 5 cm apart, and the second gear 26 is connected to the first gear The wheel 13 is aligned horizontally, a sliding groove is provided at the inner top of the receiving cavity 29 near the third gear 31, and the L-shaped connecting bracket 30 is located inside the sliding groove, the first rack 32 is meshed with the bottom end of the third gear 31, the top of the third gear 31 is meshed with the bottom end of the second rack 37, and the inner bottom end of the guide cavity 38 is symmetrically provided with slots, the bottom end of the receiving cavity 29 is flush with the inner bottom end of the guide cavity 38, the bottom end of the feed push plate 35 is in contact with the inner bottom end of the receiving cavity 29, and the side end of the L-shaped connecting bracket 30 facing away from the feed push plate 35 is 1 cm away from the side end of the third gear 31 near the receiving cavity 29.

[0043] When implementing this embodiment, when quicklime powder needs to be added to the inside of the tank body 7, the quicklime powder can be poured into the inside of the transmission vertical cylinder 36. When the receiving cavity 29 is kept in the normal position, it can be aligned with the inside of the transmission vertical cylinder 36, so that the quicklime powder can be accumulated in the receiving cavity 29. Subsequently, the driving motor 14 can be turned on to drive the supporting shaft 10, the first bevel gear 11, the stirring blade 12 and the first gear 13 to rotate at the same time. When the first gear 13 rotates, it can drive the second gear 26 to rotate, so that the second gear 26 can drive the winding wheel 25 to rotate, so that the winding wheel 25 can be pulled by the connecting rope 24 to move to the end close to the connecting rod 22, and slide into the card groove at the bottom end of the guide cavity 38 through the card key 33. The receiving cavity 29 is moved in a straight line, and when the end of the receiving cavity 29 close to the sealing plate 28 moves out of the guide cavity 38, the discharge hole 27 moves out of the guide cavity 38, so that the quicklime powder in the receiving cavity 29 can fall into the tank body 7. The biogas slurry and fermented materials are accumulated at the bottom of the tank body 7, so that the quicklime powder can fall on its surface. At the same time, the biogas slurry in the tank body 7 can be stirred when the stirring blade 12 rotates, and the second bevel gear 20 can be driven to rotate at the same time when the first bevel gear 11 rotates, so that the stirring frame 21 can rotate inside the tank body 7, so that the surface of the biogas slurry in the tank body 7 can be stirred, and the mixing uniformity of the quicklime powder and the biogas slurry in the tank body 7 can be improved. At the same time, when the receiving cavity 29 is displaced, it can also drive the third gear 31 to move at the bottom end of the second rack 37, so that the third gear 31 can drive the first rack 32 to move toward the end close to the sealing plate 28. At this time, the feeding push plate 35 will be displaced inside the receiving cavity 29, so that the feeding push plate 35 can push the quicklime powder inside the receiving cavity 29 to be evenly discharged from the inside of the discharge hole 27, thereby ensuring that the receiving cavity 29 evenly sprinkles the quicklime powder downward when displaced, avoiding the phenomenon of concentrated falling of the quicklime powder. Subsequently, when the toothed part of the first gear 13 rotates through the second gear 26, the second gear 26 will lose the meshing force, and the elasticity of the reset spring 34 will drive the receiving cavity 29 to quickly reset, so that the receiving cavity The body 29 can enter the interior of the guide cavity 38 again, and when the receiving cavity 29 is reset, the third gear 31 can be displaced along the bottom end of the second rack 37, so that the third gear 31 can drive the feed push plate 35 to move to the end away from the sealing plate 28 and reset. Subsequently, when the receiving cavity 29 is completely reset, the sealing plate 28 can be contacted and fastened with the port of the guide cavity 38, so that the interior of the guide cavity 38 can be sealed. When the device is in use, the driving motor 14 can drive the stirring blade 12 to rotate when it is started, and when the stirring blade 12 rotates, the first bevel gear 11 can drive the two second bevel gears 20 to rotate at the same time, so that the stirring frame 21 can circulate and rotate on the surface of the biogas slurry inside the tank body 7, thereby stirring the biogas slurry inside the tank body 7. At the same time,When the supporting shaft 10 rotates, the first gear 13 can be driven to mesh with the second gear 26, so that the second gear 26 can be driven to rotate. When the second gear 26 rotates, the receiving cavity 29 can be driven to move by pulling the connecting rope 24, so that the receiving cavity 29 can discharge the quicklime powder into the inside of the tank body 7 through the discharge hole 27. In addition, when the receiving cavity 29 is displaced, the third gear 31 can be moved at the bottom end of the second rack 37 to drive the feeding push plate 35 to advance inside the receiving cavity 29, so that the feeding push plate 35 can push the quicklime powder inside the receiving cavity 29 to the inside of the discharge hole 27 at a uniform speed for discharge, thereby avoiding the phenomenon of concentrated falling of quicklime powder when it is put in, and completing the work.
