Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically a high-efficiency livestock breeding wastewater treatment system. Background Technology

[0002] Livestock wastewater is one of the main pollutants generated during livestock and poultry farming. With the rapid development of large-scale farming, its discharge has been increasing year by year, posing a significant threat to the ecological environment and human health.

[0003] Patent CN210630378U discloses a livestock manure collection device, including a biogas digester and a livestock shed. The livestock shed is bolted to the top of the biogas digester. A bracket is bolted to the top of the biogas digester. Two springs are bolted to both sides of the bracket, and baffles are bolted to the top of each spring. An opening slot is provided on one side of the biogas digester located on the bracket. A nozzle is bolted to the left side of the biogas digester. Ultraviolet disinfection lamps are bolted to both sides of the livestock shed. A lighting lamp is bolted to the top of the livestock shed. This livestock manure collection device can effectively and rationally recycle manure, and there is no air pollution between the biogas digester and the livestock shed. It is an integrated device that combines cleaning, collection, and recycling.

[0004] In the prior art, the above-mentioned device separates and treats feces in sewage by using baffles, which solves the problem of fecal recycling.

[0015] The beneficial effects of this invention are: (1) The present invention can collect dirt by setting the extrusion plate, and can drive the hinge plate to close when the extrusion plate rises by setting the connecting rack and connecting gear, thereby facilitating the extrusion work of the extrusion plate. Furthermore, by setting the cleaning plate, the cleaning plate can be driven to clean the dirt on the hinge plate and the extrusion plate after the extrusion work is completed, so as to avoid the accumulation on the extrusion plate and affect the subsequent extrusion work.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-10 As shown, this application provides a high-efficiency livestock farm wastewater treatment system, including a separation chamber 1, and further comprising: Separation mechanism 2 is installed inside separation chamber 1; Filter mechanism 4 is located on one side of separation chamber 1; The water conveying mechanism 3 is located in the middle of the separation chamber 1 and the filtration mechanism 4, and is connected to each other; Water inlet pipe 5 is connected to separation mechanism 2; Wastewater enters the separation unit 2 through the inlet pipe 5. The separation unit 2 separates large pollutants from the wastewater. Then, it is transported to the filtration unit 4 through the water conveying unit 3 to filter small impurities from the wastewater. Finally, it is discharged for chemical treatment and purification. During operation, livestock wastewater is first transported to the separation mechanism 2 through the inlet pipe 5. The separation mechanism 2 separates the wastewater from the pollutants and then transports it to the separation chamber 1. The separation chamber 1 treats the wastewater and pollutants separately. The wastewater is transported to the filtration mechanism 4 through the water conveying mechanism 3 for further filtration, while the pollutants are treated and discharged. The wastewater filtered by the filtration mechanism 4 is discharged and finally treated with drugs for purification.

[0024] like Figure 2 As shown, a partition 11 is fixedly connected to the middle of the separation chamber 1; a notch 111 is provided on the partition 11; a sludge chamber 113 and a sewage chamber 112 are provided inside the separation chamber 1; the sludge chamber 113 and the sewage chamber 112 are respectively located on both sides of the partition 11; the sewage chamber 112 is connected to the water conveying mechanism 3; a hinge shaft 171 is rotatably connected to the side wall of the sludge chamber 113; a hinge plate 17 is fixedly connected to the hinge shaft 171; two sets of hinge shafts 171 are provided; a connecting groove 18 and a vertical groove 181 are provided on the side wall of the separation chamber 1; a connecting gear 172 is rotatably connected in the connecting groove 18; the output end of the connecting gear 172 is fixedly connected to the input end of the hinge shaft 171; a lifting cylinder 15 is fixedly connected to the bottom of the separation chamber 1. The lifting cylinder 15 is located inside the waste chamber 113. A pressing plate 151 is fixedly connected to the end of the lifting cylinder 15 away from the separation chamber 1. A connecting rack 153 and a sealing strip 154 ​​are fixedly connected to the side wall of the pressing plate 151. The connecting rack 153 and the connecting gear 172 are in movable engagement. The size of the sealing strip 154 ​​is the same as the inner diameter of the vertical groove 181. A discharge port 182 is opened on the side wall of the separation chamber 1. A cleaning chamber 16 is fixedly connected to the side wall of the separation chamber 1. A cleaning cylinder 161 is fixedly connected inside the cleaning chamber 16. A cleaning plate 162 is fixedly connected to the end of the cleaning cylinder 16 away from the cleaning chamber 16. The cleaning plate 162 is arranged parallel to the discharge port 182 and is located in the middle of the pressing plate 151 and the hinge plate 17. During operation, wastewater is separated by separation mechanism 2. The separated wastewater flows to wastewater chamber 112, while the waste falls into wastewater chamber 113. After entering wastewater chamber 112, the wastewater is transported to the filtration mechanism 4 by water conveying mechanism 3 for filtration. The waste accumulates on the squeezing plate 151 inside the wastewater chamber 113. After a certain period of time, the lifting cylinder 15 is driven to rise, which moves the squeezing plate 151 towards the hinge plate 17. As the squeezing plate 151 moves, it drives the connecting rack 153 connected to the side to rise. During the rise, it meshes with the connecting gear 172 in the connecting groove 18. As the squeezing plate 151 moves, it drives the connecting gear 172 to rotate. When the connecting gear 172 rotates, it drives the wastewater chamber to move. The two hinge shafts 171 within 113 rotate, thereby driving the hinge plate 17 to rotate. When the pressing plate 151 is not raised, the two hinge plates 17 are in the open state. When the pressing plate 151 rises and drives the connecting gear 172 to rotate using the connecting rack 153, the two hinge plates 17 are closed. Since the connecting rack 153 has a limited number of teeth, after the two hinge plates 17 are closed, the connecting rack 153 can no longer drive the connecting gear 172 to rotate. Then, the pressing plate 151 is continuously driven to rise until the dirt on the pressing plate 151 comes into contact with the bottom of the hinge plate 17 and is squeezed, squeezing out the residual water in the dirt and shaping the dirt. After squeezing is completed, the pressing plate 151 is driven to descend. When the pressing plate 151 descends to the level of the cleaning plate 16... When parallel, stop the operation of the lifting cylinder 15, and then use the cleaning cylinder 161 to drive the cleaning plate 162 to move towards the extrusion plate 151. When the cleaning plate 162 moves, the top of the cleaning plate 162 will contact the bottom of the hinge plate 17, and the bottom will contact the surface of the extrusion plate 151. During the movement, the dirt extruded on the dirt plate can be pushed to the discharge port 182 on one side, so that the dirt can be discharged from the discharge port 182. After the discharge is completed, the cleaning plate 162 returns to the cleaning chamber 16, and then the extrusion plate 151 continues to be driven to descend. When descending again, the connecting rack 153 drives the connecting gear 172 to rotate again, so that the hinge plate 17 opens. During the time of extrusion and cleaning, the separation work is continuous. When hinge 17 is closed, dirt falls onto it. When hinge 17 is opened, the dirt falls onto the squeeze plate 151 again. After a period of collection, the squeeze plate 151 is driven to rise again, repeating the squeezing and cleaning process. The size of the sealing strip 154 ​​is the same as the size of the vertical groove 181. When the squeeze plate 151 rises, the sealing strip 154 ​​can be used to close the vertical groove 181, preventing dirt from entering the vertical groove 181. The squeeze plate 151 can collect dirt. The connecting rack 153 and connecting gear 172 can drive the hinge 17 to close when the squeeze plate 151 rises, thus facilitating the squeezing operation of the squeeze plate 151. The cleaning plate 162 is also included.After the extrusion process is completed, the cleaning plate 162 can be driven to clean the dirt on the hinge plate 17 and the extrusion plate 151, preventing it from accumulating on the extrusion plate 151 and affecting subsequent extrusion operations. Simultaneously, the sealing plate, as the extrusion plate 151 moves, can seal the vertical groove 181, preventing dirt from entering the vertical groove 181.

[0025] like Figure 6 As shown, the filtration mechanism 4 includes a filter chamber 41; a sieve plate 42 and a filter plate 46 are fixedly connected to the side wall of the filter chamber 41; the sieve plate 42 is arc-shaped; the filter plate 46 is located below the sieve plate 42; a bidirectional lead screw 43 is rotatably connected to the side wall of the filter chamber 41; a moving block 44 is threaded onto the bidirectional lead screw 43; a cleaning brush 45 is fixedly connected to the side wall of the moving block 44; the cleaning brush 45 abuts against the filter plate 46; and a water outlet pipe 47 is fixedly connected to the bottom of the filter chamber 41. During operation, the separated wastewater reaches the top of the filter chamber 41 through the water conveying mechanism 3, and then flows down to the screen plate 42. The screen plate 42 is inclined, and after the wastewater reaches the screen plate 42, it falls with the inertia of the water flow. During the fall, the screen plate 42 filters impurities in the wastewater, and the filtered wastewater falls onto the filter plate 46 inside the filter chamber 41. The screen plate 42 and the filter plate 46 have different mesh sizes; the filter plate 46 has a larger mesh size than the screen plate 42, so it can filter out fine impurities in the wastewater. After the wastewater reaches the filter plate 46, it drives the bidirectional lead screw 43 to rotate. During rotation, the moving block 4... 4. The cleaning brush 45 moves back and forth on the filter plate 46. During the movement, it can clean the impurities on the filter plate 46 to ensure that the filter plate 46 is not blocked by dirt. The dirt on the screen plate 42 is cleaned by the continuous flow of water, thus avoiding the dirt from clogging the screen plate 42. Through the setting of the filter chamber 41, the sewage can be filtered twice and three times. The screen plate 42 is set at an angle. Under the flow of water, it can not only filter dirt, but also clean it. At the same time, through the setting of the filter plate 46 and the cleaning brush 45, small impurities in the sewage can be intercepted. Finally, it is discharged through the outlet pipe 47 and then treated with chemicals.

[0026] like Figure 2 As shown, the separation mechanism 2 includes a separation cylinder 21; the separation cylinder 21 is positioned above the separation chamber 1; a rotating shaft 22 is rotatably connected inside the separation cylinder 21; a separation plate 23 is fixedly connected to the rotating shaft 22; multiple sets of separation plates 23 are provided; a drain outlet 24, a waste outlet 25, and a water inlet 26 are provided on the side wall of the separation cylinder 21; the drain outlet 24 is located above the sewage chamber 112; the waste outlet 25 is located above the sludge chamber 113; and the water inlet 26 is connected to the water inlet pipe 5. During operation, sewage first enters the separation cylinder 21 through the inlet pipe 5. The separation cylinder 21 is equipped with multiple sets of separation plates 23, which are driven to rotate by the rotating shaft 22 in a clockwise direction. After the sewage reaches the separation cylinder 21, it first passes through the separation plates 23 to separate the waste. During separation, the sewage flows through the separation plates 23 to the drain outlet 24 below, and then flows into the sewage chamber 112. The waste is intercepted by the separation plates 23 and carried to the waste outlet 25 as the separation plates 23 rotate. When the separation plates 23 are perpendicular to the waste outlet 25, the waste loses the support of the separation plates 23 and falls into the waste chamber 113 below for treatment. The separation cylinder 21 can quickly separate the waste, and the rotating separation plates 23 can prevent the waste from accumulating on the separation plates 23 for a long time.

[0027] like Figure 2 As shown, a triangular prism 14 is fixedly connected to the side wall of the partition 11; the end of the triangular prism 14 away from the partition 11 is fixedly connected to the separation chamber 1; a striking column 141 is fixedly connected to the middle of the triangular prism 14; the striking column 141 is a spring column; the striking column 141 is located in the middle of the waste inlet 25; a groove 211 is provided in the middle of the separation cylinder 21. During operation, as the separating plate 23 rotates, it comes into contact with the striking post 141 on the triangular plate. The rotation of the separating plate 23 forces the striking post 141 to deform and bend at 90 degrees, causing the striking post 141 to be stuck inside the groove 211. When the separating plate 23 loses contact with the striking post 141, the striking post 141 will rebound and quickly strike the next set of separating plates 23, shaking off the residual dirt on the separating plate 23 into the dirt chamber 113. Then the striking post 141 bends again and strikes the next set, thereby cleaning the separating plate 23.

[0028] like Figure 2 As shown, a guide plate 12 is fixedly connected to the side wall of the sewage chamber 112; two sets of guide plates 12 are provided; an inertial shaft 13 is rotatably connected to the side wall of the sewage chamber 112; an inertial plate 131 is fixedly connected to the inertial shaft 13; multiple sets of inertial plates 131 are provided; the inertial shaft 13 and the inertial plate 131 are located below the guide plate 12; a pulley 19 is rotatably connected to the outer wall of the separation chamber 1; a pulley 49 is rotatably connected to the outer wall of the filter chamber 41; the input end of pulley 19 is fixedly connected to the output end of the inertial shaft 13; the output end of pulley 49 is fixedly connected to the input end of the bidirectional screw 43; pulley 19 and pulley 49 are connected by a belt. During operation, the wastewater separated by the separation plate 23 flows to the guide plate 12 inside the wastewater chamber 112. The wastewater is guided to the inertia plate 131 by the two sets of guide plates 12, and the inertia plate 131 rotates with the inertia of the water flow. Then, the inertia shaft 13 drives the external pulley 19 to rotate. When rotating, the pulley 49 is driven to rotate through the connected belt, thereby driving the bidirectional screw 43 inside the filter chamber 41 to rotate, thus cleaning the filter plate 46.

[0029] like Figure 2 As shown, a discharge chamber 48 is fixedly connected to the side wall of the filter chamber 41; a spiral blade 481 is rotatably installed inside the discharge chamber 48; a discharge slide 183 is fixedly connected to the side wall of the separation chamber 1; the discharge slide 183 is located below the discharge port 182. During operation, the dirt intercepted by the screen plate 42 can be washed into the discharge bin 48 by the water flow, and then the spiral blade 481 is driven to rotate to collect the dirt. Both the spiral blade 481 and the rotating shaft 22 in the separation cylinder 21 are driven by a motor, which is not shown in the figure.

[0030] like Figure 2 As shown, the water conveying mechanism 3 includes a water conveying pipe 31 and a water pump 32; the two ends of the water conveying pipe 31 are respectively connected to the separation chamber 1 and the filter chamber 41; the extrusion plate 151 is provided with a drain hole 152; the drain hole 152 is provided in several groups. During operation, sewage from the sewage chamber 112 is transported through the water supply pipe 31, and when the squeezing plate 151 squeezes the sewage, the sewage can be discharged through the drain hole 152 and then flow into the sewage chamber 112 through the notch 111 on the partition plate 11.

[0031] like Figure 1 As shown, support legs 6 are fixedly connected to the bottom of the separation chamber 1, the filter chamber 41, and the side wall of the separation cylinder 21; During operation, the support leg 6 provides support and fixation.

[0032] Working principle of the invention: After the sewage is separated by the separation mechanism 2, the separated sewage flows to the sewage chamber 112, while the sludge falls into the sludge chamber 113. After entering the sewage chamber 112, the sewage is transported to the filtration mechanism 4 by the water conveying mechanism 3 for filtration, while the sludge accumulates on the squeezing plate 151 set inside the sludge chamber 113. After a certain period of time, the lifting cylinder 15 is driven to rise, which moves the squeezing plate 151 towards the hinge plate 17. When the squeezing plate 151 moves, it drives the connecting rack 153 connected on the side to rise. During the rise, it meshes with the connecting gear 172 in the connecting groove 18, and with the movement of the squeezing plate 151, it drives the connecting rack 153 to rise. When the connecting gear 172 rotates, it drives the two combined hinge shafts 171 in the waste chamber 113 to rotate, which in turn drives the hinge plate 17 to rotate. When the pressing plate 151 is not raised, the two combined hinge plates 17 are in the open state. When the pressing plate 151 rises and the connecting rack 153 drives the connecting gear 172 to rotate, the two combined hinge plates 17 are closed. Since the connecting rack 153 has a limited number of teeth, after the two combined hinge plates 17 are closed, the connecting rack 153 can no longer drive the connecting gear 172 to rotate. Then, the pressing plate 151 continues to rise until the waste on the pressing plate 151 comes into contact with the bottom of the hinge plate 17 and is squeezed. Residual moisture in the waste is squeezed out, shaping the waste. After squeezing, the extrusion plate 151 is driven to descend. When the extrusion plate 151 descends to be parallel with the cleaning plate 162, the lifting cylinder 15 stops working. Then, the cleaning cylinder 161 drives the cleaning plate 162 to move towards the extrusion plate 151. As the cleaning plate 162 moves, its upper part contacts the bottom of the hinge plate 17, and its lower part contacts the surface of the extrusion plate 151. During the movement, the waste squeezed and shaped on the waste plate is pushed to the discharge port 182 on one side, allowing the waste to be discharged from the discharge port 182. After the discharge is completed, the cleaning plate 162 returns to the cleaning chamber 16, and then the extrusion plate is driven again. When 151 descends, the connecting rack 153 drives the connecting gear 172 to rotate again, causing the hinge plate 17 to open. During the squeezing and cleaning process, the separation work continues. The separated dirt will fall onto the hinge plate 17 when it is closed. When the hinge plate 17 is opened, the dirt will fall onto the squeezing plate 151 again. After collecting for a period of time, the squeezing plate 151 is driven to rise again, repeating the squeezing and cleaning work. The size of the sealing strip 154 ​​is the same as the size of the vertical groove 181. When the squeezing plate 151 rises, the sealing strip 154 ​​can be used to close the vertical groove 181 to prevent dirt from entering the vertical groove 181.

[0033] The separated wastewater reaches the top of the filter chamber 41 through the water conveying mechanism 3, and then flows down to the screen plate 42. The screen plate 42 is inclined. After the wastewater reaches the screen plate 42, it falls with the inertia of the water flow. During the fall, the screen plate 42 filters impurities in the wastewater. The filtered wastewater falls onto the filter plate 46 inside the filter chamber 41. The screen plate 42 and the filter plate 46 have different mesh sizes; the filter plate 46 has a larger mesh size than the screen plate 42, so it can filter out fine impurities in the wastewater. After the wastewater reaches the filter plate 46, it drives the bidirectional lead screw 43 to rotate. During rotation, the moving block 44 is used to rotate. The cleaning brush 45 moves back and forth on the filter plate 46, cleaning impurities on the filter plate 46 to prevent it from clogging. Meanwhile, the impurities on the screen plate 42 are cleaned by the continuous flow of water, preventing clogging. The filter chamber 41 allows for secondary and tertiary filtration of wastewater. The inclined screen plate 42 not only filters impurities but also cleans them under the flow of water.
