Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology for livestock farms, specifically to a water treatment device for livestock farms. Background Technology

[0002] Wastewater from pig farms flows through bar screens and filters after exiting the farm, removing most of the larger debris before entering a biogas digester. Inside the digester, organic matter undergoes hydrolysis under anaerobic conditions, transforming recalcitrant high-molecular-weight organic matter into readily biodegradable low-molecular-weight organic matter, facilitating wastewater recycling after subsequent treatment. However, in existing pig farm wastewater treatment systems, filters frequently become clogged, and cleaning is extremely inconvenient. Furthermore, wastewater treatment cannot be performed while cleaning the filters, significantly reducing the wastewater treatment rate.

[0003] Chinese patent CN215026775U discloses a wastewater recycling device for treating sewage from pig farms, comprising a box body. A groove is provided at the upper end of the box body, and a water inlet pipe slides within the groove. Openings are provided on both sides of the box body near the upper end, and filter boxes slide within each opening. A filter screen is fixedly embedded at the bottom of each filter box. Slide rails matching the filter boxes are fixedly installed on the inner walls of both sides of the box body. A metal mesh is fixedly embedded at the lower end of the box body. From bottom to top, the bottom of the box body has a fine sand filter layer, a coarse sand filter layer, and an activated carbon granule layer. A water collection hopper matching the metal mesh is fixedly installed at the lower end of the box body, and a drain pipe is fixedly installed below the water collection hopper. Support columns are fixedly installed at the four corners of the box body.

[0004] While the above solution can guarantee the wastewater treatment rate, if one filter box becomes clogged, the other filter box will start working. However, the previously clogged filter box needs to be cleaned manually. Furthermore, the filter box in the above solution has a multi-layer filtration structure. In pig farms, wastewater mainly comes from pig manure and urine. The wastewater will first settle and then be filtered. The settled wastewater will only contain a small amount of impurities, so there is no need to set up too many filtration structures. Summary of the Invention

[0005] To address the aforementioned problems, a water treatment device for aquaculture farms is provided. After a period of use, a significant amount of impurities accumulate on one side of the filter screen, leading to a reduction in flow rate at the filter screen. The reversing valve operates at fixed intervals, switching to allow new wastewater to flow into previously stagnant pipes, while the flow in previously flowing pipes stops. This reverses the flow direction of the wastewater at the filter screen, flushing down the impurities on one side of the filter screen. Simultaneously, driven by the transmission and triggering devices, the impurities in the pipes that need to flow in at this time are... When the blocking plate is in a vertical position, it obstructs the flow of wastewater. However, by installing a flexible pressure tank in the pipeline, the wastewater can flow smoothly into the pipeline and drive the transmission device. The transmission device rotates the vertical blocking plate to a horizontal position. Driven by the synchronization device, the blocking plate on the other side rotates from a horizontal to a vertical position. The transmission device also triggers the trigger device on the same side, causing the discharge device on the same side to close and the discharge device on the other side to open. In this way, the device can filter wastewater, ensuring wastewater treatment efficiency, without the need for manual cleaning of the filter screen.

[0009] Preferably, the transmission assembly includes a synchronous pulley and a synchronous belt; there are two synchronous pulleys, which are respectively located on one side of the second meshing disc and the sealing plate.

The reversing valve operates at fixed intervals, switching to allow new wastewater to flow into previously stagnant pipelines, while the flow in previously flowing pipelines ceases. This reverses the flow direction of the wastewater at the filter screen, flushing down the impurities on one side of the filter screen. Simultaneously, driven by the transmission and triggering devices, the flow rate at the filter screen is adjusted. The sealing plate in the inflow pipe is in a vertical position, which would obstruct the flow of wastewater. However, by installing a flexible pressure tank in the pipe, the wastewater can flow smoothly into the pipe and drive the transmission device. The transmission device drives the vertical sealing plate to a horizontal position. Driven by the synchronization device, the sealing plate on the other side rotates from a horizontal position to a vertical position. The transmission device also triggers the trigger device on the same side, causing the discharge device on the same side to close and the discharge device on the other side to open. In this way, the device can filter wastewater, ensuring wastewater treatment efficiency, without the need for manual cleaning of the filter screen. Attached Figure Description

Detailed Implementation

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1 , Figure 2 and Figure 7A water treatment device for aquaculture farm includes a treatment unit 1 and a sedimentation tank disposed on one side of the treatment unit 1. The treatment unit 1 includes a reversing valve 11, a pipeline 12, a sealing plate 121, a filter screen 13, a transmission device 14, a triggering device 15, a discharge device 16, and a synchronization device 17. The reversing valve 11 is disposed on one side of the sedimentation tank and operates once at fixed intervals. A connecting pipe is fixedly disposed on the side of the sedimentation tank, and a pump body is disposed on the connecting pipe. The end of the connecting pipe away from the sedimentation tank is connected to the upper part of the reversing valve 11. The pipeline 12... Two pipes 12 are provided, symmetrically arranged on both sides of the reversing valve 11. The ends of the two pipes 12 closest to the reversing valve 11 are connected to the two sides of the reversing valve 11 respectively. The pipes 12 have a semi-circular structure, and the ends of the two pipes 12 furthest from the reversing valve 11 are connected to each other. A filter screen 13 is provided at the connection point of the two pipes 12 furthest from the reversing valve 11. Two sealing plates 121 are provided, symmetrically arranged in the two pipes 12 about the filter screen 13. The sealing plates 121 are rotatably installed in the pipes 12. When the sealing plate 121 is in a horizontal state, the pipeline 12 is unobstructed; when the sealing plate 121 is in a vertical state, the pipeline 12 is blocked. The two sealing plates 121 are always in opposite states, one horizontal and one vertical, and their states can be switched. A transmission device 14 is installed on the pipeline 12, with one end of the transmission device 14 away from the pipeline 12 connected to the sealing plate 121. The liquid flowing in the pipeline 12 can drive the sealing plate 121 to rotate via the transmission device 14. A pressure tank 122 is installed on the pipeline 12 below the transmission device 14. The pressure tank 122 is a spring-loaded... The pressure tank 122 is equipped with a valve; a triggering device 15 is located on one side of the transmission device 14, and the transmission device 14 in operation can trigger the triggering device 15. A controller is located on one side of the triggering device 15; two discharge devices 16 are respectively located below the pipes 12 on both sides of the filter screen 13. After the triggering device 15 is triggered, the controller controls the discharge device 16 to open, and one of the two discharge devices 16 can be opened at a time; a synchronization device 17 is located on the side of the two sealing plates 121, and the synchronization device 17 makes the two sealing plates 121 rotate synchronously.

[0032] The pump body draws wastewater from the sedimentation tank into the reversing valve 11 via a connecting pipe. The reversing valve 11 selects one of the pipes 12 for wastewater discharge. Wastewater enters one of the pipes 12, while the water in the other pipe 12 remains stationary. The flow of wastewater drives the transmission device 14, which in turn rotates the sealing plate 121. Because a synchronization device 17 is installed between the two sealing plates 121, the rotation of one sealing plate 121 drives the rotation of the other sealing plate 121 via the synchronization device 17. The sealing plate 121 in the wastewater flow pipe 12 rotates to a horizontal position, while the sealing plate 121 in the other pipe 12 rotates to a horizontal position. The sealing plate 121 inside pipe 12 rotates to a vertical position, and at the same time, the discharge device 16 located below pipe 12 opens, while the discharge device 16 located below pipe 12 where wastewater flows is closed. Thus, wastewater can be filtered through filter screen 13 and discharged through the opened discharge device 16. After a period of use, a large amount of impurities accumulate on one side of filter screen 13, which leads to a decrease in flow rate at filter screen 13. The reversing valve 11 operates at fixed intervals, switching the flow rate and allowing new wastewater to flow into pipe 12 that was previously dry, while the previously dry pipe... The wastewater in the water flow pipe 12 stops flowing, and the flow direction of the wastewater at the filter screen 13 changes. The reverse flow of wastewater will flush down the impurities on one side of the filter screen 13. At the same time, driven by the transmission device 14 and the triggering device 15, since the blocking plate 121 in the pipe 12 that needs to flow in is in a vertical state, the blocking plate 121 will obstruct the flow of wastewater. However, the flexible pressure tank 122 installed on the pipe 12 allows the wastewater to flow smoothly into the pipe 12 and drives the transmission device 14 to operate. The transmission device 14 drives the blocking plate 121, which is in a vertical state, to rotate to a horizontal state. At the synchronization device 17 Driven by the mechanism, the sealing plate 121 on the other side rotates from horizontal to vertical. The transmission device 14 also triggers the trigger device 15 on the same side, causing the discharge device 16 on the same side to close and the discharge device 16 on the other side to open. Subsequently, the valve in the pressure tank 122 opens, and the wastewater stored in the pressure tank 122 rushes to the filter screen 13, washing off the impurities on the filter screen 13. The discharge device 16 has two discharge ports, namely the impurity discharge port and the liquid discharge port. The impurities are discharged from the impurity discharge port first, and then the waste liquid is discharged through the liquid discharge port. In this way, the device can filter the wastewater, ensuring the wastewater treatment efficiency, and there is no need for manual cleaning of the filter screen 13.

[0033] Reference Figure 1 , Figure 6 , Figure 8 and Figure 9The transmission device 14 includes a rotating blade 141, a first meshing disc 142, a second meshing disc 143, a transmission assembly 144, an extension rod 145, and a first spring 146. A rotating shell is provided on the pipeline 12, and the rotating blade 141 is rotatably disposed inside the rotating shell. The liquid flowing through the pipeline 12 can drive the rotating blade 141 to rotate. The first meshing disc 142 is fixedly disposed at the end of the rotating blade 141 along the axis of the rotating blade 141. Multiple first meshing teeth are evenly distributed around the axis of the first meshing disc 142 at the end away from the rotating blade 141, and the first meshing teeth are inclined in one direction. The second meshing disc 143 is disposed on one side of the first meshing disc 142 along the axis of the first meshing disc 142. Multiple first meshing teeth are distributed on the end of the second meshing disc 143 near the first meshing disc 142. The second meshing teeth are evenly distributed around the axis of the second meshing disk 143 and are inclined in one direction. The first and second meshing teeth mesh with each other. The two ends of the transmission assembly 144 are respectively disposed on one side of the second meshing disk 143 and one side of the sealing plate 121. The second meshing disk 143 drives the sealing plate 121 to rotate through the transmission assembly 144. The extension rod 145 is fixedly disposed at the end of the second meshing disk 143 along the axis of the second meshing disk 143 and passes through the transmission assembly 144. There is a first gap between the transmission assembly 144 and the second meshing disk 143. The first spring 146 is disposed in the first gap along the axis of the extension rod 145. The first meshing disk 142 drives the second meshing disk 143 to rotate through friction.

[0034] When wastewater flows through pipe 12, the rotating blade 141 located in the rotating housing will start to rotate. The rotating blade 141 drives the first meshing disc 142 to rotate. The second meshing disc 143 presses against the first meshing disc 142 under the elastic force of the first spring 146. The pressure of the first spring 146 provides sufficient friction between the first meshing disc 142 and the second meshing disc 143 because the first meshing disc 142 is provided with a first meshing tooth and the second meshing disc 143 is provided with a second meshing tooth. Both the first and second meshing teeth are... With a unidirectional tilt, when the first and second meshing teeth are misaligned, the first meshing disc 142 needs to overcome the frictional force of the second meshing disc 143 on the first meshing disc 142. That is, only when the sealing plate 121 rotates to the horizontal state can the first meshing disc 142 drive the second meshing disc 143 to rotate. However, during the process of the sealing plate 121 rotating from the vertical state to the horizontal state, the first meshing disc 142 can drive the second meshing disc 143 to rotate. This is because the sealing plate 121 can still rotate and does not restrict the transmission device 14.

[0035] Reference Figure 1 and Figure 4The triggering device 15 includes a first bracket 151 and a trigger button 152. The first bracket 151 is located on the side of the extension rod 145 away from the pipeline 12. Multiple trigger buttons 152 are provided. After the second engagement disc 143 is lifted by the first engagement disc 142, the extension rod 145 can trigger the trigger button 152. The trigger button 152 controls the operation of the discharge device 16 through the controller.

[0036] When the sealing plate 121 rotates to the designated state, the transmission device 14 can no longer drive the sealing plate 121 to rotate, thereby causing the second meshing disc 143 and the first meshing disc 142 to be misaligned. When the first meshing disc 142 rotates and gradually pushes the second meshing disc 143 open, the extension rod 145 set on the second meshing disc 143 will also be pushed open. The extension rod 145 slides on the transmission assembly 144, and the first spring 146 is gradually compressed. When the second meshing disc 143 is completely pushed open, the extension rod 145 can press the trigger button 152 on the first bracket 151, thereby causing the discharge device 16 on the same side to close and the discharge device 16 on the other side to open.

[0037] Reference Figures 8-10 The transmission assembly 144 includes a synchronous pulley 1441 and a synchronous belt 1442. There are two synchronous pulleys 1441, which are respectively located on one side of the second meshing disc 143 and the sealing plate 121. The synchronous pulley 1441 located on the side of the second meshing disc 143 can rotate synchronously with the second meshing disc 143, and the synchronous pulley 1441 located on the side of the sealing plate 121 can rotate synchronously with the sealing plate 121. The two ends of the synchronous belt 1442 are respectively sleeved on the two synchronous pulleys 1441, and the synchronous belt 1442 and the synchronous pulleys 1441 are in a transmission cooperation.

[0038] When the second meshing disc 143 rotates, the synchronous pulley 1441 close to the second meshing disc 143 will start to rotate. Under the transmission of the synchronous belt 1442, both synchronous pulleys 1441 will rotate, thus driving the sealing plate 121 to rotate.

[0039] Reference Figure 9 and Figure 10 The extension rod 145 is located at the non-center position of the second meshing disc 143.

[0040] Since the extension rod 145 passes through the transmission assembly 144, when the second meshing disk 143 rotates, it can drive the extension rod 145 to rotate around the axis of the second meshing disk 143, thus driving the transmission assembly 144 to rotate.

[0041] Reference Figure 8 and Figure 10The synchronization device 17 includes a first gear 171 and a second gear 172. There are two first gears 171, which are respectively located on one side of the two sealing plates 121. The synchronization wheel 1441 located on one side of the sealing plate 121 can drive the first gear 171 to rotate. The synchronization wheel 1441 drives the sealing plate 121 to rotate through the first gear 171. There is a gap between the two first gears 171. The second gear 172 is located in the gap, and its two sides mesh with the two first gears 171 respectively.

[0042] Since there are two pipes 12, each pipe 12 is equipped with a transmission component 144. The pipe 12 with the internal wastewater flow can drive the transmission component 144 on its side to rotate, thereby causing the first gear 171 to rotate. The transmission component 144 on the other side will not rotate without the action of external force. The first gear 171 on the wastewater flow side drives the second gear 172 to rotate the first gear 171 on the other side, thereby achieving the effect of synchronous rotation of the two sealing plates 121.

[0043] Reference Figure 8 and Figure 10 The processing device 1 also includes a locking device 18, which includes a second bracket 181, an electromagnet 182, a sliding rod 183, and a second spring 184. The second bracket 181 is located at the bottom of the pipeline 12, and the synchronous wheel 1441 near the sealing plate 121 is rotatably mounted on the second bracket 181. The sliding rod 183 is slidably mounted on the synchronous wheel 1441 along the axis of the synchronous wheel 1441 near the sealing plate 121. A limit ring is fixedly provided at one end of the sliding rod 183 away from the pipeline 12, and a second gap exists between the limit ring and the synchronous wheel 1441. A groove is provided on the end of the first gear 171 near the locking block, and the groove and the sliding rod 183 are engaged. The second spring 184 is located in the second gap along the axis of the sliding rod 183. The electromagnet 182 is located on the side of the sliding rod 183 away from the pipeline 12, and the electromagnet 182 is fixedly mounted on the second bracket 181.

[0044] When the transmission component 144 on the wastewater flow side drives the first gear 171 to rotate, the first gear 171 will drive the first gear 171 on the other side to rotate through the second gear 172. If the driven first gear 171 is directly connected to the transmission component 144 on its side, the first gear 171 will drive the transmission component 144 to rotate in the opposite direction. At this time, the reversing valve 11 switches, and the wastewater in the pipe 12 on its side will not flow, which will cause a jamming situation, thus preventing the first gear 171 from rotating. In order to avoid the above situation, when the reversing valve 11 switches, the electromagnet 182 is energized simultaneously, so that the sliding rod 183 that was originally engaged with the groove of the first gear 171 is disengaged. In this way, the first gear 171 on the side where the wastewater does not flow can be driven to rotate normally by the second gear 172.

[0045] Reference Figure 3 The locking device 18 also includes a limiting block 1831; the limiting block 1831 is disposed between the first gear 171 and the synchronous wheel 1441 near the first gear 171, and the limiting block 1831 is fixedly disposed on the side wall of the sliding rod 183.

[0046] The limiting block 1831 set on the sliding rod 183 can ensure that the sliding rod 183 will not disengage from the synchronous pulley 1441 when sliding.

[0047] Reference Figure 1 and Figure 5 The discharge device 16 includes a discharge pipe 161, a first switching valve 162, and a second switching valve 163. The discharge pipe 161 is vertically arranged below the pipeline 12. The first switching valve 162 is arranged at the bottom of the discharge pipe 161 and is used to discharge impurities. The second switching valve 163 is arranged on the side wall of the discharge pipe 161.

[0048] After the reversing valve 11 completes the switching, the wastewater washes the impurities off the filter screen 13. Since the wastewater in the pipe 12 on the other side does not move, the impurities can be discharged through the discharge pipe 161 and the first switch valve 162 located at the lower part of the discharge pipe 161. After a period of time, the first switch valve 162 closes and the second switch valve 163 opens. The time is set according to the actual situation, and the second switch valve 163 located on the side of the discharge pipe 161 can discharge the filtered wastewater.

[0049] Reference Figure 3 The cross-section of the sliding rod 183 near the first gear 171 is a non-circular structure.
