Abstract
Description
Technical Field
[0001] This utility model relates to the field of anaerobic fermentation technology for livestock and poultry manure, specifically an anaerobic fermentation tank for livestock and poultry manure. Background Technology
[0002] Livestock and poultry manure contains a large amount of organic matter, nitrogen, phosphorus and other pollutants. Direct discharge without treatment will lead to problems such as eutrophication of water bodies, soil pollution and air odor. Therefore, it is necessary to treat livestock and poultry manure with anaerobic fermentation. Anaerobic microorganisms decompose livestock and poultry manure and convert organic matter into biogas and biogas residue and biogas slurry. The fermented biogas residue and biogas slurry are rich in nutrients such as nitrogen, phosphorus and potassium and are high-quality organic fertilizers.
[0003] The existing anaerobic fermentation device for livestock and poultry manure mainly consists of a fermentation tank and a stirring mechanism. When treating livestock and poultry manure through anaerobic fermentation, the manure to be treated is first fed into the fermentation tank through the feed hopper. Then, anaerobic bacteria are added to the fermentation tank. Anaerobic microorganisms decompose the manure and degrade organic matter through anaerobic metabolism. The fermented biogas residue and biogas slurry are discharged through the discharge pipe and can be used as organic fertilizer for returning to the field.
[0004] Existing anaerobic fermentation devices for livestock and poultry manure cannot separate and treat wastewater and manure separately during fermentation. As a result, some nutrients cannot be effectively utilized or converted during the anaerobic fermentation process, thus affecting the fermentation effect. Therefore, an anaerobic fermentation tank for livestock and poultry manure is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes an anaerobic fermentation tank for livestock and poultry manure.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An anaerobic fermentation tank for livestock and poultry manure, comprising a box body, the box body being composed of a sewage treatment tank and a manure fermentation tank. A support base is fixedly connected to the top side of the box body, and a solid-liquid separation tank is fixedly connected to the support base. A first positioning groove is formed on the inner wall of one side wall of the solid-liquid separation tank, and a first slot is formed on the other side wall of the solid-liquid separation tank. A first filter screen is inserted into the first slot and the first positioning groove, and the first filter screen is disposed inside the solid-liquid separation tank. A first push-pull plate is fixedly connected to one end of the first filter screen. A first handle is mounted on the first push-pull plate. A sewage guide pipe is connected between the bottom side of the solid-liquid separation box and the sewage treatment tank. A manure solid feed pipe is connected between one side wall of the solid-liquid separation box and the manure fermentation tank. A manure feed hopper is connected to the top side of the solid-liquid separation box. Before fermenting livestock and poultry manure, the sewage and solid manure in the manure are separated by the first filter screen and enter the sewage treatment tank and the manure fermentation tank respectively. This facilitates the subsequent targeted treatment of sewage and manure, avoids the waste of resources and low treatment efficiency caused by mixed treatment, and greatly improves the effect of manure fermentation treatment.
[0007] Preferably, inclined grooves are provided on both inner walls of the solid-liquid separation box, and limit sliders are slidably installed in both inclined grooves. A scraper is fixed between the two limit sliders. Two pneumatic cylinders are installed on the outer wall of the solid-liquid separation box. A pneumatic rod is installed on the working end of each pneumatic cylinder, and a scraper is fixed to the other end of each pneumatic rod. In order to prevent the separated solid feces from being stuck on the first filter screen, the pneumatic cylinders, in cooperation with the inclined grooves and limit sliders, make the scraper move steadily downward along the first filter screen to scrape off and clean the residual solid feces, and let it slide down its surface, reducing the accumulation on the filter screen surface, maintaining the permeability of the filter screen, making the feeding of feces and the solid-liquid separation process smoother, and ensuring the continuity and stability of the solid-liquid separation process.
[0008] Preferably, a first rotating shaft and a second rotating shaft are rotatably installed inside the manure fermentation tank. The first rotating shaft is equipped with multiple first stirring blades, and the second rotating shaft is equipped with multiple second stirring blades. The first and second stirring blades mesh with each other. A first gear is fitted onto the top of the first rotating shaft, and a second gear is fitted onto the second rotating shaft. The first and second gears mesh with each other. A protective frame is fixed to the top side of the manure fermentation tank, and both the first and second gears are housed within the protective frame. A first electric motor is installed on the top side of the protective frame, and the output end of the first electric motor is connected to the top of the second rotating shaft. An anaerobic bacteria inlet pipe is connected to the top side of the manure fermentation tank. During manure fermentation, anaerobic bacteria are added, and the first electric motor operates, causing the first and second stirring blades to rotate in opposite directions. This ensures that the anaerobic bacteria and manure are fully contacted and mixed evenly, allowing for thorough fermentation and improving the effectiveness of the manure fermentation process.
[0009] Preferably, a second motor is installed on the top side of the sewage treatment tank. The output end of the second motor is connected to a stirring shaft, and the bottom end of the stirring shaft is rotatably mounted on a support plate. A support plate is fixed between the inner walls of both sides of the sewage treatment tank. Multiple stirring rods are fixed on the stirring shaft.

A second positioning groove is opened on one inner wall of the sewage treatment tank, and a second slot is opened on the other side of the sewage treatment tank. A second filter screen is inserted into the second slot and the second positioning groove. A second push-pull plate is fixed to one end of the second filter screen, and a second handle is mounted on the second push-pull plate. When purifying sewage, chemicals are added through the chemical dosing pipe, the second motor is started, and the stirring rods rotate, thereby stirring the sewage and fully mixing the chemicals with the sewage. This causes the fine suspended solids and colloidal particles in the sewage to agglomerate into larger particles, which fall onto the second filter screen and are intercepted. The purified water flows through the filter holes to the bottom of the sewage treatment tank and is discharged through the drain pipe.
[0010] Preferably, the wastewater treatment tank has a slag discharge port on one side, and both sides of the slag discharge port are fixedly connected to limit slide rails. The two limit slide rails are fitted with a sealing plate. When using the device, the slag discharge port facilitates the discharge of large particles of impurities after flocculation.
[0011] Preferably, the bottom port of the manure fermentation tank is connected to a fermentation product discharge pipe. A first limiting groove is provided on both sides of the bottom port of the fermentation product discharge pipe. A first sealing cover is slidably fitted onto the two first limiting grooves. A third push-pull plate is fixed to one end of the first sealing cover, and a first handle is fitted onto the third push-pull plate. The bottom port of the sewage treatment tank is connected to a drain pipe. A second limiting groove is provided on both sides of the bottom port of the drain pipe. A second sealing cover is slidably fitted onto the two second limiting grooves. A fourth push-pull plate is fixed to one end of the second sealing cover, and a second handle is fitted onto the fourth push-pull plate. When using this device, the fermentation product discharge pipe can be opened or closed as needed by the cooperation of the first limiting grooves and the first sealing cover; the drain pipe can be opened or closed as needed by the provision of the second limiting grooves and the second sealing cover.
[0012] Preferably, a control panel is installed on the outer wall of the box, and the control panel is used to control the start and stop of the first motor, the second motor and the pneumatic cylinder. The sewage treatment tank is provided with a first observation window and the fecal fermentation tank is provided with a second observation window. When using the device, the first observation window facilitates the observation of the inside of the sewage treatment tank, and the second observation window facilitates the observation of the inside of the fecal fermentation tank.
[0013] The advantages of this utility model are:
[0014] 1. Before fermenting livestock and poultry manure, this utility model separates the sewage from the solid manure through a first filter screen, and the sewage enters the sewage treatment tank and the manure fermentation tank respectively. This facilitates the subsequent targeted treatment of sewage and manure, avoids the waste of resources and low treatment efficiency caused by mixed treatment, and greatly improves the effect of manure fermentation treatment.
[0015] 2. In order to avoid the solid feces after separation remaining on the first filter screen plate, this utility model uses a pneumatic cylinder to operate. With the cooperation of the inclined slide and the limiting slider, the scraper moves steadily downward along the first filter screen plate to scrape off and clean the residual solid feces, which then slides off its surface. This reduces the accumulation on the filter screen surface, maintains the permeability of the filter screen plate, makes the feeding of feces and the solid-liquid separation process smoother, and ensures the continuity and stability of the solid-liquid separation process.
[0016] 3. In the fermentation process of feces, this utility model adds anaerobic bacteria and operates a first electric motor to rotate the first and second stirring blades in opposite directions. This allows the anaerobic bacteria to fully contact and mix with the feces, enabling thorough fermentation and improving the effectiveness of the fermentation process. Attached Figure Description

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] Please see Figure 1-2 and Figure 4-5 As shown, an anaerobic fermentation tank for livestock and poultry manure includes a box body 1, which consists of a sewage treatment tank 101 and a manure fermentation tank 102. A support base 3 is fixedly connected to the top side of the box body 1, and a solid-liquid separation tank 4 is fixedly connected to the support base 3. A first positioning groove is formed on the inner wall of one side wall of the solid-liquid separation tank 4, and a first slot is formed on the other side wall of the solid-liquid separation tank 4. A first filter screen 5 is inserted into the first groove and the first positioning groove, and the first filter screen 5 is set inside the solid-liquid separation tank 4. A first push-pull plate 6 is fixedly connected to one end of the first filter screen 5, and a first handle is mounted on the first push-pull plate 6. A sewage guide pipe 7 is connected between the bottom side of the solid-liquid separation tank 4 and the sewage treatment tank 101, and a manure fermentation tank 102 is connected between one side wall of the solid-liquid separation tank 4 and the manure fermentation tank 102. The solid feed pipe 8 and the top side of the solid-liquid separation box 4 are connected to the manure feed hopper 12. During operation, when fermenting livestock and poultry manure, the manure to be fermented is first fed into the solid-liquid separation box 4 through the manure feed hopper 12. Through the action of the first filter screen plate 5, the sewage in the manure flows into the bottom of the solid-liquid separation box 4 through the filter holes and into the sewage treatment tank 101 through the sewage guide pipe 7. The solid manure in the manure slides down along the first filter screen plate 5 and flows into the manure fermentation tank 102 through the manure solid feed pipe 8. This can separate the sewage and solid manure in the manure, which is convenient for subsequent targeted treatment of sewage and manure, avoids the waste of resources and low treatment efficiency caused by mixed treatment, and greatly improves the effect of manure fermentation treatment.
[0026] The solid-liquid separation tank 4 has inclined grooves 9 on both inner walls. Limiting sliders are slidably mounted in both inclined grooves 9, and scrapers 10 are fixedly connected between the two limiting sliders. Two pneumatic cylinders 11 are installed on the outer wall of the solid-liquid separation tank 4. Each pneumatic cylinder 11 has a pneumatic rod at its actuating end, and a scraper 10 is fixedly connected to the other end of each pneumatic rod. During operation, to prevent the separated solid feces from remaining on the first filter screen 5, the pneumatic cylinders 11 operate to move the solid feces between the inclined grooves 9 and the limiting sliders. The cooperation of the blocks enables the pneumatic rod to push the scraper 10 to move steadily along the first filter screen 5 at an angle, thereby scraping and cleaning the solid feces remaining on the first filter screen 5 and letting them slide down its surface and finally into the fecal fermentation tank 102. The timely cleaning of the residual feces reduces the accumulation on the filter screen surface, maintains the permeability of the filter screen, makes the feeding of feces and the solid-liquid separation process smoother, avoids the decrease in fecal separation efficiency caused by filter screen blockage, and ensures the continuity and stability of the solid-liquid separation process.

The top side of the manure fermentation tank 102... A protective frame 19 is fixedly attached, and both the first gear 17 and the second gear 18 are located inside the protective frame 19. A first motor 20 is installed on the top side of the protective frame 19, and the output end of the first motor 20 is connected to the top end of the second rotating shaft 14. An anaerobic bacteria inlet pipe 21 is connected to the top side of the manure fermentation tank 102, and a fermentation product discharge pipe 29 is connected to the bottom port of the manure fermentation tank 102. First limiting grooves 30 are provided on both sides of the bottom port of the fermentation product discharge pipe 29, and the two first limiting grooves 30 are fitted together in a sliding assembly. A first sealing cover plate 31 is provided, and a third push-pull plate 32 is fixedly connected to one end of the first sealing cover plate 31. A first handle is mounted on the third push-pull plate 32. During operation, solid feces flow into the feces fermentation tank 102 through the feces solid feed pipe 8. During the fermentation process, anaerobic bacteria are added into the feces fermentation tank 102 through the anaerobic bacteria inlet pipe 21. The first motor 20 is started, causing the second rotating shaft 14 to drive the second stirring blade 16 to rotate. Under the meshing action of the first gear 17 and the second gear 18... The first rotating shaft 13 drives the first stirring blade 15 to rotate, and the first stirring blade 15 and the second stirring blade 16 rotate in opposite directions, so that the anaerobic bacteria and the manure can come into full contact and mix evenly, so that the manure can be fully fermented and the effect of manure fermentation is improved. Through the decomposition of livestock and poultry manure by anaerobic microorganisms, organic matter is converted into biogas and biogas residue and biogas slurry. The fermented biogas residue and biogas slurry are rich in nutrients such as nitrogen, phosphorus and potassium, and are high-quality organic fertilizers. The fermented products are discharged through the fermentation product discharge pipe 29.
[0028] Please see Figure 1-3As shown, a second motor 24 is installed on the top side of the sewage treatment tank 101. The output end of the second motor 24 is connected to a stirring shaft 25, and the bottom end of the stirring shaft 25 is rotatably mounted on a support plate 27.

One end of the second sealing cover plate 35 is fixedly connected to a fourth push-pull plate 36, and a second handle is fitted on the fourth push-pull plate 36. During operation, sewage flows into the sewage treatment tank 101 through the sewage guide pipe 7. When purifying the sewage, the agent is added into the sewage treatment tank 101 through the agent feeding pipe 28. The second motor 24 is started, which causes the stirring shaft 25 to drive the stirring rod 26 to rotate, thereby stirring the sewage and making the agent and sewage fully mixed. This causes the fine suspended solids and colloidal particles in the sewage to agglomerate into large particles and fall onto the second filter screen plate 22, where they are intercepted. The purified water flows into the bottom of the sewage treatment tank 101 through the filter holes and is discharged through the drain pipe 33.
[0029] The wastewater treatment tank 101 has a slag discharge port on one side. Both sides of the slag discharge port are fixedly connected to limit slide rails 37.

[0031] Working Principle: Existing anaerobic fermentation devices for livestock and poultry manure cannot separate and treat wastewater and feces separately during fermentation. The mixture during anaerobic fermentation results in some nutrients not being effectively utilized or converted, thus affecting the fermentation effect. Therefore, to address this problem, an anaerobic fermentation tank for livestock and poultry manure is proposed. During fermentation, the manure to be fermented is first fed into the solid-liquid separation tank 4 through the manure feed hopper 12. Through the action of the first filter screen 5, wastewater flows through the filter holes to the bottom of the solid-liquid separation tank 4 and then into the wastewater treatment tank 101 through the wastewater guide pipe 7. Solid feces slide down along the first filter screen 5 and flow into the manure fermentation tank 102 through the solid feces guide pipe 8. This separation of wastewater and solid feces facilitates subsequent targeted treatment of wastewater and feces, avoiding resource waste and low treatment efficiency caused by mixed treatment, and greatly improving the fermentation effect.
[0032] To prevent the separated solid feces from remaining on the first filter screen plate 5, the pneumatic cylinder 11 operates, and with the cooperation of the inclined slide 9 and the limiting slider, the pneumatic rod pushes the scraper 10 to move steadily downward along the first filter screen plate 5. This scrapes and cleans the solid feces remaining on the first filter screen plate 5, which then slides down its surface and is finally put into the fecal fermentation tank 102. The timely cleaning of the residual feces reduces the accumulation on the filter screen surface, maintains the permeability of the filter screen plate, makes the feeding of feces and the solid-liquid separation process smoother, avoids the decrease in fecal separation efficiency caused by filter screen blockage, and ensures the continuity and stability of the solid-liquid separation process.
[0033] After the sewage flows into the sewage treatment tank 101 through the sewage diversion pipe 7, the sewage is purified by adding chemicals into the sewage treatment tank 101 through the chemical feeding pipe 28. The second motor 24 is started, which causes the stirring shaft 25 to drive the stirring rod 26 to rotate, thereby stirring the sewage and mixing the chemicals with the sewage. This causes the fine suspended solids and colloidal particles in the sewage to agglomerate into larger particles, which fall onto the second filter screen 22 and are intercepted. The purified water then flows through the filter holes into the bottom of the sewage treatment tank 101 and is discharged through the drain pipe 33.
[0034] Solid manure flows into the manure fermentation tank 102 through the solid manure feed pipe 8. During the fermentation process, anaerobic bacteria are added to the fermentation tank 102 through the anaerobic bacteria inlet pipe 21. The first motor 20 is started, causing the second rotating shaft 14 to drive the second stirring blade 16 to rotate. Under the meshing action of the first gear 17 and the second gear 18, the first rotating shaft 13 drives the first stirring blade 15 to rotate. The first stirring blade 15 and the second stirring blade 16 rotate in opposite directions, which allows the anaerobic bacteria to fully contact and mix with the manure, enabling the manure to undergo thorough fermentation and improving the fermentation effect. Through the decomposition of livestock and poultry manure by anaerobic microorganisms, organic matter is converted into biogas and biogas residue and biogas slurry. The fermented biogas residue and biogas slurry are rich in nutrients such as nitrogen, phosphorus, and potassium, making them high-quality organic fertilizers. The fermented products are discharged through the fermentation product discharge pipe 29.
