Description

Technical Field

[0001] The invention relates to the technical field of solid excrement processing, and more specifically to a solid excrement static composting low-temperature fermentation device. Background Art

[0002] Solid manure composting is an environmentally friendly way to convert livestock and poultry manure into organic fertilizer. It decomposes the organic matter in the manure through the metabolism of microorganisms to form decomposed fertilizer.

[0003] Among the existing solid manure composting devices, there is a solid manure static composting low-temperature fermentation device, which ferments at a relatively low temperature. Although it slows down the fermentation speed, it helps to reduce energy consumption and odor generation, thereby improving the fertilizer conversion rate. Compared with traditional dynamic composting, static composting does not require turning or mixing, reducing labor and machinery costs.

[0004] However, the current low-temperature fermentation device for static composting of solid feces requires users to discharge the gas produced by fermentation on time, which increases labor costs. When the user forgets to discharge the gas, the low-temperature fermentation device for static composting of solid feces may explode due to excessive gas pressure, which poses a serious safety hazard to the device during use.

[0005] In view of the above problems, the prior art has also proposed some solutions. For example, a Chinese patent with announcement number CN214781530U discloses a solid feces zero-emission static composting low-temperature fermentation device. The device can automatically discharge the fermentation gas after the pressure reaches a certain value through the cooperation of a pressure sensor and a solenoid valve; however, there are still certain limitations in the prior art. In the prior art, the gas discharge process needs to be driven by electricity, thereby increasing the loss of resources. In addition, thunderstorms are prone to occur in areas such as northwestern Xinjiang, central Tibet, western Sichuan, and areas south of the Yangtze River. When thunderstorms occur, power outages are likely to occur, resulting in the device being unable to discharge the fermentation gas. When the gas pressure reaches a certain level, the fermentation device has the risk of explosion, thereby leaving hidden dangers to the safety of users and causing serious economic losses. Summary of the invention

[0012] Furthermore, a filter box for filtering gas is provided on the top wall of the exhaust block, activated carbon is contained in the filter box, a first limit rod slidingly matched with a sealing plate is fixedly mounted on the bottom wall of the filter box, and a telescopic tube is fixedly mounted between the bottom wall of the linkage plate and the low-temperature fermentation box.

[0013] Furthermore, a sealing gasket that cooperates with the sealing plate is embedded on the side wall of the exhaust port, a cavity is opened on the sealing gasket, a first air pipe and a second air pipe are respectively inserted into the cavity, an exhaust valve whose output end is connected to the telescopic tube is fixedly installed on the second air pipe, an air supply assembly that cooperates with the first air pipe is provided on the exhaust block, and the first air pipe is connected to the telescopic tube through the air supply assembly.

[0014] Furthermore, the air supply assembly includes a linkage groove on the side wall of the exhaust port, a slider is slidably installed in the linkage groove, a fourth spring is fixedly installed between the slider and the linkage groove, and the side wall of the slider away from the fourth spring is an inclined surface, an air hole cooperating with the first air pipe is opened on the slider, and a connecting pipe connected with the telescopic tube is inserted on the bottom wall of the linkage groove.

[0015] Furthermore, a filter screen cooperating with the first connecting hole is embedded on the inner wall of the low-temperature fermentation box, a rotating groove is opened on the rotating rod, a push block fixedly connected to the linkage block is slidably installed in the rotating groove, and a scraper cooperating with the filter screen is fixedly installed on the rotating rod.

[0016] Furthermore, a second limiting rod extending into the exhaust port is slidably mounted on the top wall of the filter box, a cover plate is fixedly mounted on the top wall of the second limiting rod, and a fifth spring is fixedly mounted between the bottom wall of the cover plate and the filter box.

[0017] Furthermore, the inclined surface of the sliding block is a smooth mirror surface, and the sealing plate is made of metal.

[0018] Furthermore, the bottom wall of the low-temperature fermentation box is an inclined surface, a plug plate is detachably mounted on the bottom wall of the low-temperature fermentation box, and a transparent glass plate is embedded on the side wall of the low-temperature fermentation box.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) In this scheme, a sealing plate is provided. When the pressure in the low-temperature fermentation box increases, the sealing plate is driven to move upward, and then gradually loses contact with the exhaust port as the sealing plate moves upward. At this time, the gas in the low-temperature fermentation box can be discharged to the outside, and after the sealing plate loses contact with the exhaust port, the first connecting rod can fix the sealing plate, thereby ensuring normal pressure relief of the low-temperature fermentation box, that is, the low-temperature fermentation box can be automatically exhausted and depressurized without external force, which plays a role in improving the safety of the fermentation device;

[0021] (2) In this scheme, a linkage plate is set. After the sealing plate is fitted with the top wall of the first connecting rod, the second magnet drives the fixing rod to disengage from the fixing groove through the first magnet. At this time, the first spring drives the linkage plate to move downward. In the process of the linkage plate moving downward, it gradually contacts the inclined surface of the second connecting rod and drives the vertical rod to move through the second connecting rod. At this time, the elastic airbag is connected to the low-temperature fermentation box, and then the gas in the low-temperature fermentation box expands it and prevents the vertical rod from moving. When the pressure in the low-temperature fermentation box gradually returns to normal, the elastic airbag gradually shrinks and resets. At this time, the linkage plate drives the first connecting rod to disengage from the sealing plate through the second connecting rod and the vertical rod. At this time, the sealing plate moves downward and fits with the linkage plate again, and the exhaust port is blocked, thereby further improving the pressure relief effect of the low-temperature fermentation box.

[0022] (3) This scheme provides a rotating groove. When the airflow passes through the first connecting hole and enters the exhaust groove, the filter can be set to block the impurities in the airflow, thereby effectively preventing the impurities from entering the exhaust groove and affecting the normal movement of the sealing plate. Then, when the linkage plate moves upward, the linkage plate is connected to the low-temperature fermentation box through the telescopic tube, and the linkage plate cannot rotate. Then, during the movement of the linkage plate, the push block and the rotating groove drive the rotating rod to rotate. During the rotation of the rotating rod, the scraper is driven to clean the impurities on the bottom wall of the filter, thereby effectively preventing the impurities from clogging the filter, resulting in the low-temperature fermentation box being unable to release pressure normally, and further improving the safety of the fermentation device.

[0033] See also Figures 1 to 7 , a low-temperature fermentation device for static composting of solid feces, comprising a low-temperature fermentation box 1;

[0034] It also includes an exhaust component, which includes an exhaust block 201 fixedly mounted on the top wall of the low-temperature fermentation box 1, an exhaust port 202 is provided on the exhaust block 201, a connecting port 203 connected to the exhaust port 202 is provided on the top wall of the exhaust block 201, and the diameter of the connecting port 203 is larger than the diameter of the exhaust port 202, a first connecting hole connected to the exhaust port 202 is provided on the low-temperature fermentation box 1, a sealing plate 204 is slidably installed in the exhaust port 202, a rotating rod 205 extending into the exhaust port 202 is rotatably installed on the low-temperature fermentation box 1, and a sliding mounting is installed on the rotating rod 205. There is a linkage plate 206, and a connecting component is provided between the linkage plate 206 and the sealing plate 204, a first spring 207 is fixedly installed between the bottom wall of the linkage plate 206 and the low-temperature fermentation box 1, a slide groove is provided on the exhaust block 201, a vertical rod 208 is slidably installed in the slide groove, a first connecting rod 209 and a second connecting rod 210 are fixedly installed on the top wall and the bottom wall of the vertical rod 208 respectively, and the ends of the first connecting rod 209 and the second connecting rod 210 away from the vertical rod 208 are both inclined surfaces, and a second spring 211 is fixedly installed between the side wall of the vertical rod 208 and the slide groove.

[0035] The connecting assembly includes a connecting plate 301 fixedly mounted on the top wall of the linkage plate 206, a vertical groove cooperating with the connecting plate 301 is formed on the sealing plate 204, a fixing rod 302 is horizontally slidably mounted on the side wall of the vertical groove, a third spring 303 is fixedly mounted between one end of the fixing rod 302 away from the connecting plate 301 and the sealing plate 204, a fixing groove 304 cooperating with the fixing rod 302 is formed on the connecting plate 301, a first magnet 305 is embedded in the fixing rod 302, and a second magnet 306 that attracts the first magnet 305 is fixedly mounted on the top wall of the first connecting rod 209.

[0036] An elastic air bag 401 is embedded on the side wall of the slide, an air supply pipe 402 is inserted into the elastic air bag 401, a push rod 403 is inserted into the top wall of the low-temperature fermentation box 1, a return spring 404 is solidly fixedly installed between the bottom wall of the push rod 403 and the low-temperature fermentation box 1, a groove is provided on the low-temperature fermentation box 1, a sealing rod 405 is slidably installed in the groove, a horizontal spring 406 is fixedly installed between the side wall of the sealing rod 405 and the groove, a vertical hole 407 connected to the air supply pipe 402 is provided on the sealing rod 405, and a vertical pipe 408 connected to the low-temperature fermentation box 1 is inserted on the bottom wall of the groove.

[0037] In the initial state, the first spring 207 is in a freely extended state, and the second spring 211 is in a stretched state. When the solid feces in the low-temperature fermentation box 1 ferments to produce gas, the gas pressure in the low-temperature fermentation box 1 gradually increases, and then under the action of pressure, the sealing plate 204 drives the interlocking plate 206 to move upward. At this time, the first spring 207 is stretched and has a tendency to recover. During the upward movement of the interlocking plate 206, it gradually disengages from the second connecting rod 210. At this time, the second spring 211 contracts and drives the first connecting rod 209 and the second connecting rod 210 to move toward the rotating rod 205. Then, as the gas pressure in the low-temperature fermentation box 1 gradually increases, the sealing plate 204 gradually moves upward. During the upward movement of the sealing plate 204, it gradually contacts the inclined surface of the first connecting rod 209 and applies a thrust to the inclined surface of the first connecting rod 209. When the body pressure reaches the value required for pressure relief and exhaust, the sealing plate 204 pushes the first connecting rod 209 to move, and during the movement of the first connecting rod 209, the vertical rod 208 is driven to stretch the second spring 211. When the sealing plate 204 is out of contact with the inclined surface of the first connecting rod 209, the top wall of the sealing plate 204 is in contact with the top wall of the first connecting rod 209, and at this time, under the action of the first connecting rod 209, the sealing plate 204 cannot move downward. At the same time, when the bottom wall of the sealing plate 204 is in contact with the top wall of the first connecting rod 209, the sealing plate 204 is out of contact with the exhaust port 202 and enters the connecting port 203. Then, the gas in the low-temperature fermentation box 1 can flow to the outside through the first connecting hole, the exhaust port 202, and the connecting port 203. In addition, the low-temperature fermentation box 1 can be exhausted according to the pressure value without the help of external force, thereby improving the safety of the fermentation device.

[0038] In the initial state, the third spring 303 is in a free extension state, and then the sealing plate 204 moves upward, driving the first magnet 305 to gradually approach the second magnet 306, and when the bottom wall of the sealing plate 204 contacts the top wall of the first connecting rod 209, the distance between the first magnet 305 and the second magnet 306 reaches the shortest, at this time the suction force between the first magnet 305 and the second magnet 306 reaches the maximum, and then under the action of the suction force, the first magnet 305 drives the fixing rod 302 to disengage from the fixing groove 304, at this time the third spring 303 is compressed, and then the first spring 207 contracts and drives the linkage plate 206 to move downward, and in the process of the linkage plate 206 moving downward, it gradually contacts the inclined surface of the second connecting rod 210 and applies a thrust to the inclined surface of the second connecting rod 210, and then under the action of the thrust, the second connecting rod 210 drives the first connecting rod 210 through the vertical rod 208 The connecting rod 209 moves, and the second spring 211 is stretched at this time. It gradually loses contact with the sealing plate 204 during the movement of the first connecting rod 209, and then the sealing plate 204 moves downward under the action of gravity. During the downward movement of the sealing plate 204, it drives the first magnet 305 and the second magnet 306 to gradually move away, and then the third spring 303 stretches and drives the fixing rod 302 to reset. As the sealing plate 204 moves downward, the connecting plate 301 is inserted into the vertical groove again. During the insertion of the connecting plate 301 into the vertical groove, it gradually contacts the inclined surface of the fixing rod 302 and applies a thrust to the inclined surface of the fixing rod 302. Then, under the action of the thrust, the fixing rod 302 moves and compresses the third spring 303. When the fixing groove 304 contacts the fixing rod 302, the third spring 303 stretches and drives the fixing rod 302 to insert into the fixing groove 304, thereby preparing for exhaust again.

[0039] In the initial state, the return spring 404 and the horizontal spring 406 are both in a compressed state. During the upward movement of the linkage plate 206, the return spring 404 stretches and drives the push rod 403 to move upward. When the sealing plate 204 is out of contact with the inclined surface of the first connecting rod 209, the push rod 403 is out of contact with the sealing rod 405. Then the horizontal spring 406 stretches and drives the sealing rod 405 to move. During the movement of the sealing rod 405, the vertical hole 407 is driven to contact with the vertical tube 408. At this time, the gas in the low-temperature fermentation box 1 flows into the elastic airbag 401 through the vertical tube 408, the vertical hole 407, and the air supply pipe 402, and the elastic airbag 401 is expanded, thereby increasing the passage of the linkage plate 206. The resistance when the vertical rod 208 is pushed by the second connecting rod 210, that is, when the pressure in the low-temperature fermentation box 1 is relatively high, the linkage plate 206 cannot push the vertical rod 208 to move through the second connecting rod 210. As the gas continues to flow to the outside, the pressure in the low-temperature fermentation box 1 gradually decreases. At this time, the elastic airbag 401 gradually shrinks. When the pressure in the low-temperature fermentation box 1 returns to normal, the elastic airbag 401 shrinks and returns to a normal state. At this time, the linkage plate 206 is reset through the second connecting rod 210, the vertical rod 208, and the first connecting rod 209, thereby ensuring that the sealing plate 204 moves downward normally and fits with the top wall of the linkage plate 206, thereby ensuring that the exhaust work can be carried out normally, further improving the safety of the fermentation device.

[0040] like Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown, a filter box 501 for filtering gas is provided on the top wall of the exhaust block 201, and activated carbon is contained in the filter box 501. A first limiting rod 502 that slidably cooperates with the sealing plate 204 is fixedly installed on the bottom wall of the filter box 501, and a telescopic tube 503 is fixedly installed between the bottom wall of the linkage plate 206 and the low-temperature fermentation box 1.

[0041] A sealing gasket 601 cooperating with the sealing plate 204 is embedded on the side wall of the exhaust port 202, a cavity is opened on the sealing gasket 601, a first air pipe 602 and a second air pipe 603 are respectively inserted into the cavity, an exhaust valve 604 whose output end is connected to the telescopic tube 503 is fixedly installed on the second air pipe 603, an air supply component cooperating with the first air pipe 602 is provided on the exhaust block 201, and the first air pipe 602 is connected to the telescopic tube 503 through the air supply component.

[0042] The air supply component includes a linkage groove provided on the side wall of the exhaust port 202, a slider 701 is slidably installed in the linkage groove, a fourth spring 702 is fixedly installed between the slider 701 and the linkage groove, and the side wall of the slider 701 away from the fourth spring 702 is an inclined surface, an air hole 703 cooperating with the first air pipe 602 is provided on the slider 701, and a connecting pipe 704 connected with the telescopic tube 503 is inserted on the bottom wall of the linkage groove.

[0043] By adopting the above technical solution, the telescopic tube 503 is driven to telescope back and forth during the reciprocating motion of the linkage plate 206, and then the linkage plate 206 can be limited during the telescopic movement of the telescopic tube 503, thereby effectively preventing the linkage plate 206 from rotating. In addition, by setting the first limiting rod 502, the sealing plate 204 can be limited, thereby ensuring that the connecting plate 301 can be accurately inserted into the vertical groove during the resetting of the sealing plate 204. In the process of the gas flowing to the outside through the connecting port 203, the gas will first pass through the filter box 501, and then the activated carbon in the filter box 501 can absorb the irritating gas in the gas, thereby reducing pollution.

[0044] In the initial state, the fourth spring 702 is in a free extension state. In the process of the first spring 207 driving the interlocking plate 206 to move downward, the gas in the telescopic tube 503 is gradually squeezed and tends to flow to the outside. Then, as the sealing plate 204 moves downward, it gradually contacts the inclined surface of the slider 701 and applies a thrust to the inclined surface of the slider 701. Then, under the action of the thrust, the slider 701 moves along the interlocking groove and squeezes the fourth spring 702. In the process of the movement of the slider 701, the air hole 703 is driven to move. When the sealing plate 204 is fitted with the interlocking plate 206, the slider 701 drives the air hole 703 to communicate with the first air pipe 602. At this time, the gas in the telescopic tube 503 flows into the cavity through the second air pipe 603, the air hole 703, and the first air pipe 602, and makes the sealing pad 601 expand. Then the expanded sealing pad 601 is tightly fitted with the sealing plate 204, thereby increasing the air tightness between the sealing plate 204 and the exhaust port 202, thereby improving the fermentation effect.

[0045] When the linkage plate 206 drives the telescopic tube 503 to extend, the telescopic tube 503 absorbs air from the cavity through the exhaust valve 604 and the connecting pipe 704, and then the sealing pad 601 contracts and resets, thereby ensuring that the sealing plate 204 moves downward normally.

[0046] like Figure 3 , Figure 6As shown, a filter screen 801 cooperating with the first connecting hole is embedded on the inner wall of the low-temperature fermentation box 1, a rotating groove 802 is opened on the rotating rod 205, a push block 803 fixedly connected to the linkage block is slidably installed in the rotating groove 802, and a scraper 804 cooperating with the filter screen 801 is fixedly installed on the rotating rod 205.

[0047] A second limiting rod 901 extending into the exhaust port 202 is slidably mounted on the top wall of the filter box 501 , a cover plate 902 is fixedly mounted on the top wall of the second limiting rod 901 , and a fifth spring 903 is fixedly mounted between the bottom wall of the cover plate 902 and the filter box 501 .

[0048] By adopting the above technical solution, in the process of air flow entering the exhaust groove through the first connecting hole, the filter 801 can be set to block impurities in the air flow, thereby effectively preventing impurities from entering the exhaust groove and affecting the normal movement of the sealing plate 204. Then, in the process of the linkage plate 206 moving upward, since the linkage plate 206 is connected to the low-temperature fermentation box 1 through the telescopic tube 503, the linkage plate 206 cannot rotate. Then, in the process of the linkage plate 206 moving, the push block 803 and the rotating groove 802 drive the rotating rod 205 to rotate. In the process of the rotating rod 205 rotating, the scraper 804 is driven to clean the impurities on the bottom wall of the filter 801, thereby effectively preventing impurities from clogging the filter 801, resulting in the low-temperature fermentation box 1 being unable to release pressure normally, and further improving the safety of the fermentation device.

[0049] In the initial state, the fifth spring 903 is in a freely extended state. Then, when the bottom wall of the sealing plate 204 contacts the top wall of the first connecting rod 209, the sealing plate 204 drives the cover plate 902 to disengage from the filter box 501 through the second limiting rod 901. At this time, the gas can flow normally through the filter box 501 to the outside. The setting of the cover plate 902 can prevent external impurities from falling to the top wall of the filter box 501 and causing the filter box 501 to be blocked, and gradually disengage from the second limiting rod 901 during the downward movement of the sealing plate 204. At this time, the fifth spring 903 contracts and drives the cover plate 902 to move downward. During the downward movement of the cover plate 902, it gradually fits with the top wall of the filter box 501, thereby effectively preventing moisture and impurities in the outside air from entering the filter box 501 when no exhaust is performed, causing the activated carbon to be quickly saturated, thereby extending the service life of the activated carbon.

[0050] like Figure 2 , Figure 7 As shown, the inclined surface of the slider 701 is a smooth mirror surface, and the sealing plate 204 is made of metal.

[0051] The bottom wall of the low-temperature fermentation box 1 is an inclined surface, a plug plate 10 is detachably mounted on the bottom wall of the low-temperature fermentation box 1 , and a transparent glass plate 11 is embedded on the side wall of the low-temperature fermentation box 1 .

[0052] By adopting the above technical solution, in the process of the sealing plate 204 driving the slider 701 to move, by making the inclined surface of the slider 701 a smooth mirror surface, the friction between the inclined surface of the slider 701 and the sealing plate 204 can be reduced, thereby ensuring that the sealing plate 204 can normally drive the slider 701 to move, and by making the sealing plate 204 a metal material, since the metal material has a higher density, the gravity of the metal material of the same volume is greater, thereby increasing the power of the sealing plate 204 when moving downward, thereby ensuring that the sealing plate 204 moves downward normally.

[0053] When the fermentation of the solid fertilizer is finished, the user can open the plug plate 10 to take out the fertilizer, and can also observe the fermentation and taking-out of the solid waste in the low-temperature fermentation box 1 through the transparent glass plate 11 .

[0054] Instructions for use: When the solid feces in the low-temperature fermentation box 1 ferments to produce gas, the gas pressure in the low-temperature fermentation box 1 gradually increases, and then the sealing plate 204 drives the linkage plate 206 to move upward under the action of the pressure. In the process of the sealing plate 204 moving upward, it gradually contacts the inclined surface of the first connecting rod 209 and applies a thrust to the inclined surface of the first connecting rod 209. When the gas pressure in the low-temperature fermentation box 1 reaches a value that requires pressure relief and exhaust, the sealing plate 204 pushes the first connecting rod 209 to move, and in the process of the first connecting rod 209 moving, it drives the vertical rod 208 to stretch the second spring 211. When the sealing plate 204 is out of contact with the inclined surface of the first connecting rod 209, the top wall of the sealing plate 204 is in contact with the top wall of the first connecting rod 209, and at this time, the sealing plate 204 cannot move downward under the action of the first connecting rod 209. At the same time, when the bottom wall of the sealing plate 204 is in contact with the top wall of the first connecting rod 209, the sealing plate 204 is out of contact with the exhaust port 202 and enters the connecting port 203, and then the gas in the low-temperature fermentation box 1 can flow to the outside through the first connecting hole, the exhaust port 202, and the connecting port 203; when the bottom wall of the sealing plate 204 is in contact with the top wall of the first connecting rod 209, the first The suction force between the magnet 305 and the second magnet 306 reaches the maximum, and then the first magnet 305 drives the fixing rod 302 to disengage from the fixing groove 304 under the action of the suction force, and then the first spring 207 contracts and drives the linkage plate 206 to move downward, and gradually contacts with the inclined surface of the second connecting rod 210 during the downward movement of the linkage plate 206, and drives the first connecting rod 209 to move through the second connecting rod 210 and the vertical rod 208, and gradually disengages from the sealing plate 204 during the movement of the first connecting rod 209, and then the sealing plate 204 moves downward under the action of gravity, and the sealing plate 204 moves downward under the action of gravity. During the downward movement, the first magnet 305 and the second magnet 306 are gradually moved away from each other, and then the third spring 303 stretches and drives the fixing rod 302 to reset. As the sealing plate 204 moves downward, the connecting plate 301 is inserted into the vertical groove again. During the process of the connecting plate 301 being inserted into the vertical groove, it gradually contacts the inclined surface of the fixing rod 302 and applies a thrust to the inclined surface of the fixing rod 302. Then, under the action of the thrust, the fixing rod 302 moves and compresses the third spring 303. When the fixing groove 304 contacts the fixing rod 302, the third spring 303 stretches and drives the fixing rod 302 to insert into the fixing groove 304.
