Description
Technical Field
[0001] The invention relates to the technical field of feces recycling equipment, and in particular to a dehydration device and a dehydration method for recycling feces in a breeding farm. Background Art
[0002] The development of modern animal husbandry and the rise of factory-based intensive farming have enriched people's material needs, but have also brought about the proliferation of livestock wastewater, causing pollution to water sources, air, and the environment. In order to protect water sources, air, and the environment, livestock manure needs to be recycled. In this process, livestock manure needs to be dehydrated and the raw manure and wastewater from livestock and poultry manure needs to be separated into liquid organic fertilizer and solid organic fertilizer.
[0003] Among them, the most common way to dehydrate feces is to rely on a screw extruder, which uses the extrusion effect of the rotating screw to squeeze out the water in the feces and separate the solid and liquid parts. However, since the feces in farms are often mixed with urine, or are exposed to a large amount of water during flushing and cleaning, the overall water content is high, which makes the solid content in the screw extruder low. As a result, the pressure generated by the screw extrusion may not be enough to effectively squeeze out all the liquid, resulting in incomplete dehydration and affecting the dehydration effect of the feces. Summary of the invention
[0004] In order to solve the above technical problems, the present invention provides a dehydration device for recycling farm feces, comprising a dehydration mechanism, the dehydration mechanism also comprising a screw extruder, a dehydration box is fixedly connected to the outer wall of the screw extruder, a drum screen is rotatably connected to the inner wall of the dehydration box, and a drainage plate is fixedly connected to the inner wall of the dehydration box; The dredging mechanism includes three air collecting hoods fixedly connected to the top of the inner wall of the dehydration box, the inner walls of the three air collecting hoods are all slidably connected with spring piston rods, and the tops of the three air collecting hoods are all connected with air pipes; The cleaning mechanism comprises three rotating frames rotatably connected to the inner wall of the guide plate, three scrapers are arranged on the inner wall of the drum screen, and arc scrapers are fixedly connected to the side walls of the three scrapers.
[0005] Preferably, the dehydration mechanism further comprises a motor fixedly connected to the top of the dehydration box, the bottom output end of the motor is fixedly connected to a rotating rod, a fixed rod is sleeved on the outer wall of the rotating rod, the top of the fixed rod is fixedly connected to the top of the inner wall of the dehydration box, a start switch is fixedly connected to the bottom of the inner wall of the dehydration box, and a stop switch is fixedly connected to the top of the inner wall of the dehydration box; Among them, four reset springs are fixedly connected to the bottom of the inner wall of the dewatering box, three sliding frames are fixedly connected to the outer wall of the fixed rod, and three connecting frames are arranged on the inner wall of the drum screen. A slider is fixedly connected to the inner wall of the drum screen, and the outer wall of the slider is slidably connected to the inner wall of the rotating rod. The staff injects feces from the feed port on the top of the dewatering box, and the feces entering the dewatering box will be guided by the drainage plate to flow into the drum screen. As the feces enters, the weight of the drum screen itself will gradually increase, causing the drum screen to descend and squeezing the reset spring. The drum screen will contact the start switch during the descent process. At this time, the motor will start to drive the rotating rod to rotate, and the staff will stop injecting feces into the dewatering box. When the rotating rod rotates, the drum screen is driven to rotate by the slider on the drum screen to throw the liquid in the feces out into the dewatering box.
[0006] Preferably, the dehydration mechanism further comprises a sewage pipe connected to the bottom of the dehydration box, the inner walls of the three connecting frames are rotatably connected with the extrusion roller one, the inner walls of the three extrusion rollers one are rotatably connected with a plurality of extrusion rollers two, the inner walls of the three connecting frames are slidably connected with the inner wall of the sliding frame, the inner wall of the drum screen is provided with a cam groove, and the inner wall of the cam groove is slidably connected with the outer wall of the connecting frame; Among them, a pushing rod is sleeved on the outer wall of the rotating rod, and a spring telescopic rod 1 is fixedly connected to the top of the pushing rod, and the top of the spring telescopic rod 1 is fixedly connected to the top of the fixed rod, and a fixed sleeve is fixedly connected to the inner wall of the fixed sleeve. The discharged liquid is discharged through the sewage pipe. As the moisture in the feces decreases, the weight of the drum screen will decrease, and it will rise under the influence of the rebound force of the reset spring. At this time, when the drum screen rotates, the solids in the feces will be affected by the centrifugal force and approach the inner wall of the drum screen. At the same time, when the drum screen rotates, the cam groove will drive the connecting frame to move up and down, so that the extrusion roller 1 moves, and drives the extrusion roller 2 to move. When the drum screen rotates, the extrusion roller 1 is affected by the friction force of the inner wall of the drum screen, and it will rotate, thereby squeezing the solid feces and separating the moisture inside it.
[0007] Preferably, the dehydration mechanism further comprises a moving rod rotatably connected to the top of the drum screen, a blocking plate 1 is rotatably connected to the bottom of the inner wall of the drum screen, an arc spring 1 is fixedly connected to the bottom of the drum screen, a side wall of the arc spring 1 is fixedly connected to the side wall of the blocking plate 1, a sliding groove is provided on the inner wall of the drum screen, and a spring push block is slidably connected to the inner wall of the sliding groove; Among them, a spring block is slidably connected to the inner wall of the sliding groove, and the outer wall of the spring block is slidably connected to the inner wall of the blocking plate 1. When the extrusion roller 2 reciprocates up and down and contacts the inner wall of the drum screen, the extrusion roller 2 is affected by the friction force and rotates, rubbing the feces back and forth, so that the feces and the inner wall of the drum screen are more fully contacted, which promotes the discharge of water, and then the dehydrated feces are discharged into the screw extruder for dehydration again, so as to avoid the high liquid content of the feces, resulting in a smaller spiral extrusion force on the solid matter in the feces, and the water in the feces is difficult to be squeezed out, so that the solid content of the feces in the screw extruder is increased, so that the feces can be fully squeezed by the spiral, ensuring the dehydration effect of the feces.
[0008] Preferably, the dredging mechanism also includes three jet plates fixedly connected to the bottom of the drainage plate, the side walls of the three jet plates are connected through the outer wall of the air pipe, the inner walls of the three air pipes are rotatably connected with annular baffles, the tops of the spring piston rods are fixedly connected with connecting plates, and the side walls of the three annular baffles are fixedly connected with arc springs 2. The force of the connecting frame moving is utilized, and when the extrusion roller 1 squeezes the solid feces, the connecting frame will contact the spring piston rod when it rises, pushing the spring piston rod to rise, squeezing the gas in the air collecting hood, and the The squeezed gas will be blocked by the annular baffle, causing the gas in the gas collecting hood to generate high pressure. When the spring piston rod moves, it will also drive the connecting plate to rise until the connecting plate contacts the annular baffle. At this time, the annular baffle will be pushed and rotated, squeezing the arc spring 2. At the same time, it will also cancel the obstruction to the gas, allowing the compressed gas to enter the gas pipe, and be transported to the jet plate through the gas pipe, and then sprayed onto the drum screen through the jet plate. As the drum screen rotates, the sprayed gas will backblow the drum screen to remove impurities in the holes of the drum screen and make the holes unobstructed.
[0009] Preferably, the cleaning mechanism further comprises a limit rod slidably connected to the inner wall of the arc-shaped scraper, the tops of the three limit rods are fixedly connected to the bottom of the gas collecting hood, the inner walls of the three scrapers are slidably connected to spring return rods, the bottoms of the three connecting frames are fixedly connected to push plates, and the outer walls of the three spring return rods are fixedly connected to three extrusion blocks; Among them, the outer walls of the three scrapers are slidably connected to the inner wall of the rotating frame, and the inner walls of the three rotating frames are slidably connected to the outer wall of the spring piston rod. The force of the spring piston rod will push the rotating frame to move when the spring piston rod rises, so that the rotating frame will be tilted, the scraper will descend, and the arc scraper will be driven to descend. At this time, the extrusion roller will rise and the scraper will descend, so that the extrusion roller and the scraper will move alternately. Since the extrusion roller will rotate, the scraper will cover more surface areas of the extrusion roller when the extrusion roller rotates, which can ensure that the scraper can contact more attached impurities and scrape off the feces attached to the surface of the extrusion roller.
[0010] Preferably, the cleaning mechanism also includes three fixed blocks fixedly connected to the inner wall of the scraper, the inner walls of the three fixed blocks are slidably connected to the outer wall of the spring return rod, the three arc-shaped scrapers are provided with air delivery grooves inside, the side walls of the three arc-shaped scrapers are fixedly connected to two air outlet pipes, the inner walls of the two air outlet pipes are fixedly connected to guide plates, the inner walls of the two air outlet pipes are rotatably connected to baffle plates 2, the side walls of the two baffle plates 2 are fixedly connected to arc springs 3, and the force of the scraper movement is utilized to alternately move the extrusion roller 1 and the scraper When the air pressure increases, the second blocking plate will be pushed to rotate, eliminating the obstruction to the gas, causing the gas to be ejected along the bottom of the second blocking plate, blowing the feces that have fallen on the arc-shaped scraper and causing it to fall off the arc-shaped scraper.
[0011] A dehydration method of a dehydration device for recycling farm feces, comprising the following steps: S1: The staff injects feces from the feed port on the top of the dehydration box. The feces entering the dehydration box will be guided by the drainage plate and flow into the drum screen. As the feces enters, the weight of the drum screen will gradually increase, causing the drum screen to drop. S2: The drum screen will contact the start switch during the descent process. At this time, the motor will start to drive the rotating rod to rotate. When the rotating rod rotates, the drum screen is driven to rotate through the slider on the drum screen, and the liquid in the feces is thrown out into the dehydration box. The discharged liquid is discharged through the sewage pipe. As the water content in the feces decreases, the weight of the drum screen will decrease; S3: When the drum screen rotates, the solids in the feces will be affected by the centrifugal force and approach the inner wall of the drum screen. At the same time, when the drum screen rotates, it will drive the connecting frame to move up and down through the cam groove, so that the extrusion roller moves to squeeze the solid feces and separate the water inside it.
[0012] The present invention has the following beneficial effects: (1) When the present invention is used, the staff injects feces into the dehydration box from the feed port at the top of the dehydration box. The feces entering the dehydration box will be guided by the drainage plate and flow into the drum screen. As the feces enter, the weight of the drum screen itself will gradually increase, causing the drum screen to descend and squeezing the reset spring. The drum screen will contact the start switch during the descent process. At this time, the motor will start to drive the rotating rod to rotate, and the staff will stop injecting feces into the dehydration box. When the rotating rod rotates, the drum screen is driven to rotate through the slider on the drum screen, and the liquid in the feces is thrown into the dehydration box. The discharged liquid is discharged through the sewage pipe. As the water content in the feces decreases, the weight of the drum screen will decrease, and it will rise under the influence of the rebound force of the reset spring. At this time, when the drum screen rotates, the solids in the feces will be affected by the centrifugal force and approach the inner wall of the drum screen. At the same time, when the drum screen rotates, The cam groove will drive the connecting frame to move up and down, so that the extrusion roller one moves, and the extrusion roller two moves. When the drum screen rotates, the extrusion roller one is affected by the friction of the inner wall of the drum screen and will rotate, squeezing the solid feces to separate the water inside it. When the extrusion roller two moves up and down and contacts the inner wall of the drum screen, the extrusion roller two is affected by the friction and will rotate, rubbing the feces back and forth, so that the contact between the feces and the inner wall of the drum screen is more complete, which promotes the discharge of water. The dehydrated feces is then discharged into the screw extruder for dehydration again to avoid a high liquid content in the feces, which results in a smaller spiral extrusion force on the solid matter in the feces, making it difficult to squeeze out the water in the feces, and increasing the solid content of the feces in the screw extruder, so that the feces can be fully spirally extruded to ensure the dehydration effect of the feces.
[0013] (2) The present invention utilizes the force of the movement of the connecting frame. When the extrusion roller 1 extrude solid feces, at this time, the connecting frame will contact the spring piston rod when it rises, pushing the spring piston rod to rise and squeezing the gas in the gas collecting hood. At this time, the squeezed gas will be blocked by the annular baffle, causing the gas in the gas collecting hood to generate high pressure. When the spring piston rod moves, it will also drive the connecting plate to rise until the connecting plate contacts the annular baffle. At this time, the annular baffle will be pushed and rotated, squeezing the arc spring 2, and at the same time, it will cancel the obstruction to the gas, allowing the compressed gas to enter the air supply pipe, be transported to the jet plate through the air supply pipe, and be sprayed onto the drum screen through the jet plate. As the drum screen rotates, the sprayed gas will back-blow the drum screen, remove impurities in the holes of the drum screen, and make the holes unobstructed, thereby avoiding the feces entering the holes of the drum screen when squeezing, causing the drum screen to be blocked, affecting the subsequent dehydration of feces, ensuring that the liquid can flow out smoothly, and maintaining good dehydration efficiency.
[0014] (3) The present invention utilizes the force of the spring piston rod to move. When the spring piston rod rises, it will push the rotating frame to move, causing the rotating frame to tilt, causing the scraper to descend, and driving the arc scraper to descend. At this time, the extrusion roller one will rise, and the scraper will descend, causing the extrusion roller one and the scraper to move alternately. Since the extrusion roller one rotates, the scraper will cover more surface areas of the extrusion roller one when the extrusion roller one rotates, ensuring that the scraper can contact more attached impurities and scrape off the feces attached to the surface of the extrusion roller one. At the same time, when the arc scraper reciprocates, it cooperates with the rotation of the drum screen to scrape off the feces attached to the drum screen, so that the extrusion roller one remains clean and tidy, and the feces are prevented from adhering to the surface of the extrusion roller one and affecting the extrusion effect, thereby maintaining a good extrusion effect. In addition, the inner wall of the drum screen is scraped, and the feces separated from the holes when the drum screen is backblown are quickly scraped to the bottom of the drum screen, ensuring that the backblown impurities are no longer retained on the screen surface, reducing the possibility of hole blockage.
[0015] (4) The present invention utilizes the force of the scraper movement. When the extrusion roller 1 and the scraper move alternately, the spring return rod will contact the push plate during movement, and the spring return rod will be squeezed, pushing the extrusion block to move, squeezing the gas in the scraper. The squeezed gas will enter the gas outlet pipe through the gas conveying groove and be guided to the bottom of the baffle plate 2 by the guide plate. At this time, the gas will be blocked by the baffle plate 2, causing the gas to generate high pressure. As the gas pressure continues to increase, it will push the baffle plate 2 to rotate, eliminating the obstruction to the gas, causing the gas to spray out along the bottom of the baffle plate 2, blowing the feces that fell on the arc scraper and causing it to fall off the arc scraper, thereby preventing the feces scraped off by the top arc scraper from falling onto the top of the bottom arc scraper when the arc scraper is scraping off the feces, causing the feces to accumulate and affecting the scraping effect of the arc scraper, thereby ensuring that the cleaning effect of each arc scraper is maximized.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] For example, see Figure 1 - Figure 7 The present invention is a dehydration device for recycling farm feces, comprising a dehydration mechanism 1, wherein the dehydration mechanism 1 further comprises a screw extruder 101, a dehydration box 102 is fixedly connected to the outer wall of the screw extruder 101, a drum screen 103 is rotatably connected to the inner wall of the dehydration box 102, and a drainage plate 104 is fixedly connected to the inner wall of the dehydration box 102; The dredging mechanism 2 includes three air collecting covers 201 fixedly connected to the top of the inner wall of the dehydration box 102, the inner walls of the three air collecting covers 201 are all slidably connected with spring piston rods 202, and the tops of the three air collecting covers 201 are all connected with air delivery pipes 203; The cleaning mechanism 3 comprises three rotating frames 301 rotatably connected to the inner wall of the guide plate 104 , three scrapers 302 are arranged on the inner wall of the drum screen 103 , and arc-shaped scrapers 303 are fixedly connected to the side walls of the three scrapers 302 .
[0021] The dehydration mechanism 1 also includes a motor 105 fixedly connected to the top of the dehydration box 102, a rotating rod 106 is fixedly connected to the bottom output end of the motor 105, a fixed rod 107 is sleeved on the outer wall of the rotating rod 106, the top of the fixed rod 107 is fixedly connected to the top of the inner wall of the dehydration box 102, a start switch 118 is fixedly connected to the bottom of the inner wall of the dehydration box 102, and a stop switch 119 is fixedly connected to the top of the inner wall of the dehydration box 102; Among them, four return springs 108 are fixedly connected to the bottom of the inner wall of the dehydration box 102, three sliding frames 109 are fixedly connected to the outer wall of the fixed rod 107, and three connecting frames 111 are arranged on the inner wall of the drum screen 103. A slider is fixedly connected to the inner wall of the drum screen 103, and the outer wall of the slider is slidably connected to the inner wall of the rotating rod 106. The staff injects feces from the feed port at the top of the dehydration box 102, and the feces entering the dehydration box 102 will be guided by the drainage plate 104 so that the feces flows into the inlet. As feces enter the drum screen 103, the weight of the drum screen 103 itself will gradually increase, causing the drum screen 103 to descend and squeezing the return spring 108. The drum screen 103 will contact the start switch 118 during the descending process. At this time, the motor 105 will start to drive the rotating rod 106 to rotate, and the staff will also stop injecting feces into the dehydration box 102. When the rotating rod 106 rotates, the slider on the drum screen 103 drives the drum screen 103 to rotate, and the liquid in the feces is thrown out into the dehydration box 102.
[0022] The dehydration mechanism 1 also includes a sewage pipe 110 connected to the bottom of the dehydration box 102, the inner walls of the three connecting frames 111 are rotatably connected to the squeezing roller 1 112, the inner walls of the three squeezing rollers 112 are rotatably connected to a plurality of squeezing rollers 2 113, the inner walls of the three connecting frames 111 are slidably connected to the inner wall of the sliding frame 109, the inner wall of the drum screen 103 is provided with a cam groove 114, and the inner wall of the cam groove 114 is slidably connected to the outer wall of the connecting frame 111; Among them, the outer wall of the rotating rod 106 is sleeved with a push rod 116, the top of the push rod 116 is fixedly connected with a spring telescopic rod 115, the top of the spring telescopic rod 115 is fixedly connected to the top of the fixed rod 107, the top of the push rod 116 is fixedly connected with a fixed sleeve, and the inner wall of the fixed sleeve is slidably connected with a spring telescopic rod 2 117. The discharged liquid is discharged through the sewage pipe 110. As the moisture in the feces decreases, the weight of the drum screen 103 will decrease, and the rebound force of the reset spring 108 will be reduced. At this time, when the drum screen 103 rotates, the solids in the feces will be affected by the centrifugal force and approach the inner wall of the drum screen 103. At the same time, when the drum screen 103 rotates, the cam groove 114 will drive the connecting frame 111 to move up and down, so that the extrusion roller 112 moves, and the extrusion roller 2 113 moves. When the drum screen 103 rotates, the extrusion roller 112 is affected by the friction force of the inner wall of the drum screen 103 and rotates, thereby squeezing the solid feces and separating the water inside it.
[0023] The dehydration mechanism 1 also includes a moving rod 120 rotatably connected to the top of the drum screen 103, a blocking plate 121 is rotatably connected to the bottom of the inner wall of the drum screen 103, an arc spring 122 is fixedly connected to the bottom of the drum screen 103, the side wall of the arc spring 122 is fixedly connected to the side wall of the blocking plate 121, a sliding groove is opened on the inner wall of the drum screen 103, and a spring push block 123 is slidably connected to the inner wall of the sliding groove; The inner wall of the sliding groove is slidably connected with a spring block 124, and the outer wall of the spring block 124 is slidably connected with the inner wall of the blocking plate 121. When the extrusion roller 113 reciprocates up and down and contacts the inner wall of the drum screen 103, the extrusion roller 113 is affected by the friction force and rotates, rubbing the feces back and forth, so that the feces and the inner wall of the drum screen 103 are more fully contacted, promoting the discharge of water, and then the dehydrated feces are discharged into the screw extruder 101 for re-dehydration to avoid the high liquid content of the feces, which causes the solid matter in the feces to be affected by the spiral extruder. The pressure is small, and the water in the feces is difficult to be squeezed out, so that the solid content of the feces in the screw extruder 101 increases, so that the feces can be fully squeezed by the screw, ensuring the dehydration effect of the feces; wherein, when the drum screen 103 and the start switch 118 are in contact, the drum screen 103 will separate from the push rod 116, because the spring telescopic rod 115 and the spring telescopic rod 2 117 are in a squeezed state before separation, after separation, the rebound force of the spring telescopic rod 115 will be released to push the push rod 116 to move, and the rebound force of the spring telescopic rod 2 117 will also be released to contact the bottom of the inner wall of the drum screen 103, such as: Figure 6 As shown, when the weight in the drum screen 103 decreases and rises, the spring telescopic rod 117 is squeezed until the drum screen 103 contacts the push rod 116, such as: Figure 7 As shown, at this time, the drum screen 103 rotates to drive the blocking plate 121 and the spring push block 123 to move until they come into contact with the pushing rod 116. Since the contact surfaces of the spring push block 123 and the pushing rod 116 are both inclined surfaces, the pushing rod 116 will squeeze the spring push block 123, allowing the spring push block 123 to descend and cancel the obstruction of the spring block 124. Since the spring block 124 is in a stretched state, after the obstruction is cancelled, the rebound force of the spring block 124 will be released and returned to its position, canceling the obstruction to the blocking plate 121. At this time, the rebound force of the spring telescopic rod 2 117 will push the blocking plate 121 to move, squeezing the arc spring 122, allowing the bottom of the drum screen 103 to open, so that the dehydrated feces can be discharged.
[0024] For example 2, please refer to Figure 8 - Fig.12The present invention is a dehydration device for recycling feces in a farm. On the basis of the first embodiment, the dredging mechanism 2 also includes three jet plates 204 fixedly connected to the bottom of the drainage plate 104. The side walls of the three jet plates 204 are connected to the outer wall of the air pipe 203. The inner walls of the three air pipes 203 are rotatably connected with an annular baffle 206. The top of the spring piston rod 202 is fixedly connected with a connecting plate 205. The side walls of the three annular baffles 206 are fixedly connected with an arc spring 2 207. The force of the connecting frame 111 moving is used to squeeze the solid feces when the extrusion roller 112 squeezes the solid feces. At this time, when the connecting frame 111 rises, it will contact the spring piston rod 202, push the spring piston rod 202 to rise, and squeeze The gas in the gas collecting hood 201 will be blocked by the annular baffle 206 at this time, so that the gas in the gas collecting hood 201 will generate high pressure. When the spring piston rod 202 moves, it will also drive the connecting plate 205 to rise until the connecting plate 205 contacts the annular baffle 206. At this time, the annular baffle 206 will be pushed and rotated, squeezing the arc spring 207, and at the same time, the obstruction to the gas will be eliminated, allowing the compressed gas to enter the air supply pipe 203, and be transported to the jet plate 204 through the air supply pipe 203, and then be sprayed onto the drum screen 103 through the jet plate 204. As the drum screen 103 rotates, the sprayed gas will back-blow the drum screen 103 to remove impurities in the holes of the drum screen 103 and make the holes unobstructed.
[0025] The cleaning mechanism 3 also includes a limit rod 304 slidably connected to the inner wall of the arc-shaped scraper 303, the tops of the three limit rods 304 are fixedly connected to the bottom of the gas collecting cover 201, the inner walls of the three scrapers 302 are slidably connected to spring return rods 305, the bottoms of the three connecting frames 111 are fixedly connected to push plates 306, and the outer walls of the three spring return rods 305 are fixedly connected to three extrusion blocks 308; Among them, the outer walls of the three scrapers 302 are slidably connected to the inner wall of the rotating frame 301, and the inner walls of the three rotating frames 301 are slidably connected to the outer wall of the spring piston rod 202. The force of the spring piston rod 202 when moving will push the rotating frame 301 to move when the spring piston rod 202 rises, so that the rotating frame 301 is tilted, the scraper 302 is lowered, and the arc scraper 303 is driven to fall. At this time, the extrusion roller 112 will rise, and the scraper 302 will fall, so that the extrusion roller 112 and the scraper 302 will move alternately. Since the extrusion roller 112 will rotate, the scraper 302 will cover more surface areas of the extrusion roller 112 when the extrusion roller 112 rotates, which can ensure that the scraper 302 can contact more attached impurities and scrape off the feces attached to the surface of the extrusion roller 112.
[0026] The cleaning mechanism 3 also includes three fixed blocks 307 fixedly connected to the inner wall of the scraper 302, the inner walls of the three fixed blocks 307 are slidably connected to the outer wall of the spring return rod 305, the three arc-shaped scrapers 303 are provided with air delivery grooves 310, the side walls of the three arc-shaped scrapers 303 are fixedly connected to two air outlet pipes 309, the inner walls of the two air outlet pipes 309 are fixedly connected to guide plates 311, the inner walls of the two air outlet pipes 309 are rotatably connected to blocking plates 2 312, and the side walls of the two blocking plates 2 312 are fixedly connected to arc springs 313. The force of the scraper 302 moving is used to squeeze the roller 112 and the scraper 302. During the staggered motion, the spring return rod 305 will contact the push plate 306, and the spring return rod 305 will be squeezed, pushing the squeezing block 308 to move, squeezing the gas in the scraper 302, and the squeezed gas will enter the gas outlet pipe 309 through the gas conveying groove 310, and be guided to the bottom of the second blocking plate 312 by the guide plate 311. At this time, the gas will be blocked by the second blocking plate 312, allowing the gas to generate high pressure. As the air pressure continues to increase, it will push the second blocking plate 312 to rotate, canceling the obstruction to the gas, and causing the gas to spray out along the bottom of the second blocking plate 312, blowing the feces that have fallen on the arc scraper 303 and falling off the arc scraper 303.
[0027] The dehydration method of the dehydration device for recycling manure in the farm includes the following steps: S1: The staff injects feces from the feed port on the top of the dehydration box 102. The feces entering the dehydration box 102 will be guided by the guide plate 104 to flow into the drum screen 103. As the feces enter, the weight of the drum screen 103 will gradually increase, causing the drum screen 103 to drop. S2: The drum screen 103 will contact the start switch 118 during the descending process. At this time, the motor 105 will start to drive the rotating rod 106 to rotate. When the rotating rod 106 rotates, the drum screen 103 is driven to rotate through the slider on the drum screen 103, and the liquid in the feces is thrown out into the dewatering box 102. The discharged liquid is discharged through the sewage pipe 110. As the water content in the feces decreases, the weight of the drum screen 103 will decrease; S3: When the drum screen 103 rotates, the solids in the feces will be affected by the centrifugal force and approach the inner wall of the drum screen 103. At the same time, when the drum screen 103 rotates, the cam groove 114 will drive the connecting frame 111 to move up and down, so that the extrusion roller 112 moves to squeeze the solid feces and separate the water inside.
[0028] A specific application of this embodiment is: when the present invention is used, the staff injects feces from the feed port on the top of the dehydration box 102, and the feces entering the dehydration box 102 will be guided by the guide plate 104 to flow into the drum screen 103. As the feces enter, the weight of the drum screen 103 will gradually increase, causing the drum screen 103 to drop, squeezing the reset spring 108. The drum screen 103 will contact the start switch 118 during the descending process. At this time, the motor 105 will start to drive the rotating rod 10 6 rotates, the staff will also stop injecting feces into the dewatering box 102. When the rotating rod 106 rotates, the slider on the drum screen 103 drives the drum screen 103 to rotate, and the liquid in the feces is thrown out into the dewatering box 102. The discharged liquid is discharged through the sewage pipe 110. As the water content in the feces decreases, the weight of the drum screen 103 will decrease, and it will rise under the influence of the rebound force of the reset spring 108. At this time, when the drum screen 103 rotates, the solids in the feces will be affected by the centrifugal force and close to the drum screen 103. 03, at the same time, when the drum screen 103 rotates, the cam groove 114 will drive the connecting frame 111 to move up and down, so that the extrusion roller 112 moves, and the extrusion roller 2 113 moves. When the drum screen 103 rotates, the extrusion roller 112 is affected by the friction of the inner wall of the drum screen 103, and it will rotate to squeeze the solid feces to separate the water inside. When the extrusion roller 2 113 reciprocates up and down and contacts the inner wall of the drum screen 103, the extrusion roller 2 113 is affected by the friction. The effect will cause the rotation, rubbing the feces back and forth, so that the feces are more fully in contact with the inner wall of the drum screen 103, promoting the discharge of water, and then the dehydrated feces are discharged into the screw extruder 101 for dehydration again, so as to avoid the high liquid content of the feces, resulting in a small spiral extrusion force on the solid matter in the feces, and the water in the feces is difficult to be squeezed out, so that the solid content of the feces in the screw extruder 101 is increased, so that the feces can be fully squeezed by the spiral, ensuring the dehydration effect of the feces; When the drum screen 103 and the start switch 118 are in contact, the drum screen 103 will separate from the push rod 116. Since the spring telescopic rod 1 15 and the spring telescopic rod 2 117 are in a squeezed state before separation, after separation, the rebound force of the spring telescopic rod 1 15 will be released to push the push rod 116 to move, and the rebound force of the spring telescopic rod 2 117 will also be released to contact the bottom of the inner wall of the drum screen 103, such as: Figure 6 As shown, when the weight in the drum screen 103 decreases and rises, the spring telescopic rod 117 is squeezed until the drum screen 103 contacts the push rod 116, such as: Figure 7As shown, at this time, the drum screen 103 rotates to drive the blocking plate 121 and the spring push block 123 to move until they come into contact with the pushing rod 116. Since the contact surfaces of the spring push block 123 and the pushing rod 116 are both inclined surfaces, the pushing rod 116 will squeeze the spring push block 123, allowing the spring push block 123 to descend and cancel the obstruction of the spring block 124. Since the spring block 124 is in a stretched state, after the obstruction is cancelled, the rebound force of the spring block 124 will be released and returned to its original position, canceling the obstruction of the blocking plate 121. At this time, the rebound force of the spring telescopic rod 2 117 will push the blocking plate 121 to move, squeezing the arc spring 122, so that the bottom of the drum screen 103 is opened, so that the dehydrated feces can be discharged. As the drum screen 103 rotates, feces will be discharged continuously, and the drum screen 103 will also rise until the moving rod 120 contacts the stop switch 119, the motor 105 will stop, and then feces will be injected again to dehydrate the feces. When the blocking plate 121 is separated from the pushing rod 116, the resilience of the arc spring 122 will be released, pushing the blocking plate 121 back to its original position. When the blocking plate 121 returns to its original position, it will push the spring pushing block 123 to rise and contact the spring clamping block 124. Since the contact surfaces of the spring pushing block 123 and the spring clamping block 124 are both inclined surfaces, the spring pushing block 123 will smoothly squeeze the spring clamping block 124 to move, allowing the spring clamping block 124 to be inserted into the blocking plate 121 to block the incoming feces. Secondly, when the extrusion roller 112 extrude solid feces, the connecting frame 111 will contact the spring piston rod 202 when it rises, pushing the spring piston rod 202 to rise, squeezing the gas in the gas collecting hood 201. At this time, the squeezed gas will be blocked by the annular baffle 206, so that the gas in the gas collecting hood 201 will generate high pressure. When the spring piston rod 202 moves, it will also drive the connecting plate 205 to rise until the connecting plate 205 contacts the annular baffle 206. At this time, the annular baffle 206 will be pushed and rotated to squeeze the arc spring 207. At the same time, the gas obstruction is removed, allowing the compressed gas to enter the gas pipe 203, and then be transported to the jet plate 204 through the gas pipe 203, and then be ejected onto the drum screen 103 through the jet plate 204. As the drum screen 103 rotates, the ejected gas will back-blow the drum screen 103, remove the impurities in the holes of the drum screen 103, and make the holes unobstructed, so as to avoid the feces entering the holes of the drum screen 103 when squeezing the feces, causing the drum screen 103 to be blocked, thus affecting the subsequent dehydration of the feces, ensuring that the liquid can flow out smoothly, and maintaining a good dehydration efficiency; Secondly, when the spring piston rod 202 rises, it will push the rotating frame 301 to move, so that the rotating frame 301 will tilt, and the scraper 302 will drop, driving the arc scraper 303 to drop. At this time, the extrusion roller 112 will rise, and the scraper 302 will drop, so that the extrusion roller 112 and the scraper 302 will move alternately. Since the extrusion roller 112 will rotate, the scraper 302 will cover more surface areas of the extrusion roller 112 when the extrusion roller 112 rotates, which can ensure that the scraper 302 can contact more attached impurities and remove the extrusion roller 112. The feces attached to the surface of the drum screen 103 are scraped off. At the same time, the arc scraper 303 scrapes off the feces attached to the drum screen 103 when it moves back and forth, in coordination with the rotation of the drum screen 103, so that the extrusion roller 112 is kept clean and tidy, and the feces are prevented from adhering to the surface of the extrusion roller 112 to affect the extrusion effect, thereby maintaining a good extrusion effect; in addition, the inner wall of the drum screen 103 is scraped off, and the feces separated from the holes when the drum screen 103 is backblown are quickly scraped off to the bottom of the drum screen 103, ensuring that the backblown impurities are no longer retained on the screen surface, reducing the possibility of hole blockage; Secondly, when the extrusion roller 112 and the scraper 302 move alternately, the spring return rod 305 will contact the push plate 306, and the spring return rod 305 will be squeezed, pushing the extrusion block 308 to move, squeezing the gas in the scraper 302, and the squeezed gas will enter the outlet pipe 309 through the gas conveying groove 310, and be guided by the guide plate 311 to the bottom of the second blocking plate 312. At this time, the gas will be blocked by the second blocking plate 312, so that the gas will generate high pressure. As the gas pressure continues to increase , it will push the second blocking plate 312 to rotate, eliminating the obstruction to the gas, allowing the gas to be ejected along the bottom of the second blocking plate 312, blowing the feces that have fallen on the arc scraper 303 and causing it to fall off the arc scraper 303, thereby preventing the feces scraped by the top arc scraper 303 from falling onto the top of the bottom arc scraper 303 when the arc scraper 303 is scraping off the feces, causing feces to accumulate and affecting the scraping effect of the arc scraper 303, thereby ensuring that the cleaning effect of each arc scraper 303 is maximized.
