[0030] As Figure 1As shown in the figure, an anaerobic composting device of the present invention includes a water seal tank 1 and a composting ground 4. Both the water seal tank 1 and the composting ground 4 are cast with concrete and subjected to waterproof sealing treatment. The water seal tank 1 is in a "return" shape surrounding the composting ground 4; a pressing rod mechanism 2 is arranged on the ground outside the water seal tank 1; materials are piled on the composting ground 4, and a biogas film 3 is covered above the materials. The edge of the biogas film 3 is placed in the water seal tank 1, and the water seal tank 1 is filled with water or other liquids with good airtightness. In the working state, the liquid level height reaches more than 80% of the depth of the water seal tank.

[0031] As Figure 2 shown in the figure, it is a structural schematic diagram of the pressing rod mechanism 2. The base 201 is fixedly installed on the concrete ground, and a support column 203 is welded to the top of the base 201; an operating rod rotating shaft 204 is provided at the top of the support column 203, and the operating rod 205 and the intermediate arm 206 are rotatably installed on the top of the support column 203 through the operating rod rotating shaft 204; the other end of the intermediate arm 206 is provided with a forearm rotating shaft 207, and the upper part 210 of the forearm is rotatably installed at the other end of the intermediate arm 206 through the forearm rotating shaft 207; the lower part 211 of the forearm is movably connected to the upper part 210 of the forearm, and a pressing part 213 is fixedly installed at the bottom of the lower part 2 of the forearm; a forearm reinforcing rib 212 is fixedly connected between the lower part 211 of the forearm and the pressing part 213; a connecting rod 202 is rotatably installed between the lower part 211 of the forearm and the support column 203 through a pin shaft; two locking connecting rods 208 are rotatably installed between the upper part 210 of the forearm and the support column 203 through pin shafts. The locking connecting rod 208 is provided with elongated slot holes, and a locking bolt 209 is detachably installed in the two elongated slot holes. When the locking bolt 209 is inserted into the elongated slot holes of the two locking connecting rods 208 at the same time, the relative positions of the two locking connecting rods 208 can be locked. In the non-working state, the locking bolt 209 is removed, and the two locking connecting rods 208 can be in an active state; the upper part of the support column 203, the intermediate arm ......

[0032] As Figure 3 shown in the figure, it is a partial enlarged structural view of the pressing rod mechanism 2. An arrester pawl dial rotating shaft 214 is arranged near the operating rod rotating shaft 204 of the operating rod 205. The arrester pawl dial rotating shaft 214 penetrates through the connecting part of the operating rod 205, the support column 203 and the intermediate arm 206 and extends into the intermediate arm 206; outside the intermediate arm 206, an arrester pawl dial 215 is rotatably installed on the arrester pawl dial rotating shaft 214, and the arrester pawl dial rotating shaft......

[0033] As Figure 4The figure shown is a partial side sectional view of the lever mechanism 2. Inside the intermediate arm 206, a double-acting ratchet 216 is mounted on the operating lever rotation shaft 204, and the double-acting ratchet 216 can rotate synchronously with the intermediate arm 206; a pawl 217 is rotatably mounted on the pawl lever rotation shaft 214, which is used to actuate the lever mechanism. Figure 3 The pawl 215 in the middle can control the rotation of the pawl 217.

[0034] A spring mechanism 218 is provided between the upper part 210 of the forearm and the lower part 211 of the forearm, so that the upper part 210 of the forearm and the lower part 211 of the forearm can generate a small relative movement in the axial direction.

[0035] like Figure 5 The image shows an enlarged view of the bidirectional ratchet 216. A bidirectional return spring 219 is provided between the pawl pawl rotation shaft 214 and the pawl 217. The bidirectional return spring 219 can limit the axial rotation of the pawl 217 and reset its position.

[0036] When pawl 217 is in Figure 5 As shown by the solid line, when the operating lever 205 is rotated counterclockwise, the pawl pawl rotation axis 214 simultaneously rotates counterclockwise around the operating lever rotation axis 204, causing the pawl 217 to rotate counterclockwise. The pawl head 217a presses against the side of the bidirectional ratchet tooth 216a, causing the bidirectional ratchet 216 to rotate counterclockwise, thereby driving the intermediate arm 206 to rotate counterclockwise around the operating lever rotation axis 204.

[0037] When the operating lever 205 is rotated counterclockwise to a certain angle, and the pawl 217 is pressed against the inner wall of the intermediate arm 206, or the angle of the operating lever 205 is no longer convenient for operation, causing the operating lever 205 to be unable to continue rotating counterclockwise, the operating lever 205 is rotated clockwise. This causes the pawl lever rotation shaft 214 and the pawl 217 to rotate clockwise. The pawl 217 is springed open by the top 216b of the double-direction ratchet teeth and is reset by the double-direction return spring 219, causing the side 217b of the pawl teeth to re-engage in the gap 216c of the double-direction ratchet teeth. The operating lever 205 is rotated clockwise in this way until the pawl 217 is engaged in the appropriate position of the double-direction ratchet 216. At this point, the operating lever 205 can be rotated counterclockwise again to cause the intermediate arm 206 to rotate counterclockwise around the operating lever rotation shaft 204.

[0038] Move the pawl lever 215 so that the pawl 217 rotates to... Figure 5 At the position indicated by the dotted line, performing the reverse operation of the above steps will cause the intermediate arm 206 to rotate clockwise.

[0039] like Figure 6 and Figure 7The diagram shows the working state of the water seal trough 1 and the pressure rod mechanism 2. During the sealing operation of the biogas membrane 3, water is injected into the water seal trough 1, and the edge of the biogas membrane 3 is brought into contact with the bottom surface 11 of the water seal trough. The operating rod 205 is rotated counterclockwise, causing the intermediate arm 206 to rotate counterclockwise around the operating rod's rotation axis 204. This causes the upper part 210 and the lower part 211 of the forearm to move downwards, bringing the pressing part 213 into contact with the edge of the biogas membrane 3. Continuing to rotate the operating rod 205 counterclockwise, a spring mechanism 2 is provided between the upper part 210 and the lower part 211 of the forearm. 18, so that the pressing part 213, the edge of the biogas membrane 3 and the bottom surface 11 of the water seal groove form a line contact at point A, generating a large clamping force on the edge of the biogas membrane 3. After pressing the biogas membrane 3, the locking bolt 209 is simultaneously inserted into the elongated slot of the two locking rods 208 and tightened, so that the relative position of the two locking rods 208 is locked, and at the same time the positions of the upper part of the forearm 210, the lower part of the forearm 211 and the pressing part 213 are locked, thereby completing the sealing operation of the biogas membrane 3.

[0040] like Figure 8 and Figure 9 The image shows the second embodiment of the present invention. In this embodiment, two circular steel pipes 12 are pre-embedded at the bottom of the water seal trough 1. When performing the sealing operation of the biogas membrane 3, water is injected into the water seal trough 1, and the edge of the biogas membrane 3 is placed between the pressing part 213 and the circular steel pipes 12. The operating rod 205 is rotated counterclockwise so that the pressing part 213, the edge of the biogas membrane 3, and the circular steel pipes 12 simultaneously form line contact at points B and C, making the biogas membrane 3 more firmly and stably clamped.

[0041] like Figure 10 The image shows the third embodiment of the present invention. In this embodiment, the water seal groove 1 is an arc-shaped groove, and the pressing part 213 is an arc-shaped steel pipe with the same diameter as the water seal groove 1. Depending on actual needs, when the material stacking ground 4 is circular, the arc-shaped pressing part 213 can also achieve a good pressure sealing effect.
