Abstract
Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment and purification device and method for livestock farming. Background Technology
[0002] Large-scale farming is an inevitable trend in the development of animal husbandry and a major indicator of its modernization. However, with the development of large-scale farming, the amount of wastewater generated will also increase, necessitating rapid wastewater treatment to prevent direct discharge and environmental pollution.
[0003] CN213171500U discloses a livestock wastewater treatment device, relating to the field of livestock equipment. This device includes a storage tank connected to an oil drain pipe and a water drain pipe, both equipped with valves. A threaded pipe is inserted into the top of the storage tank, and a funnel with a filter screen is sealed to the top of the threaded pipe. This livestock wastewater treatment device can separate solid residues and oil from wastewater, making it suitable for treating wastewater containing large amounts of impurities and oil from livestock farms.
[0004] In existing technologies, the filter screen and other components in the aforementioned devices achieve the filtration and treatment of aquaculture wastewater. However, in aquaculture farms, wastewater comes from many sources, such as feces, feed residues, veterinary drug residues, and hair. This wastewater requires multiple filtration processes to completely remove impurities. However, the aforementioned devices only use the filter screen for single-pass filtration, which inevitably affects the filtration effect. Furthermore, during long-term filtration, impurities can clog the filter screen. The traditional method is to replace the entire filter screen after a period of use. However, this requires shutting down the equipment. For large-scale aquaculture farms, equipment shutdown can lead to wastewater accumulation. Restarting the equipment will increase the workload of the filtration device, causing it to overload and affecting its lifespan. Summary of the Invention

[0014] A method for treating and purifying wastewater used in livestock farming includes the following steps: S1, wastewater is injected into the pretreatment chamber through the inlet pipe, and then the impurities in the wastewater are crushed by the crushing rod, which facilitates coarse filtration by the water screen plate below. The filtered wastewater enters the filter cylinder through the pipe, while the impurities flow into the waste discharge chamber for discharge. S2, after coarse filtration, the wastewater enters the filter cylinder and drives the filter cylinder to rotate. When rotating, the wastewater will be finely filtered. The filtered wastewater will then flow into the outlet pipe and be discharged, while the impurities will remain in the filter cylinder and then be discharged into the collection bin. S3, after the impurities in the filter cartridge enter the collection chamber, they undergo final filtration in the collection chamber to separate the impurities from the wastewater, and finally are discharged through the second outlet pipe for further treatment.
[0015] The beneficial effects of this invention are: (1) The present invention can facilitate the filtration of large impurities in wastewater by setting the water screen plate. At the same time, the cleaning plate can clean the impurities on the water screen plate and speed up the filtration of the water screen plate. The cleaning plate is movable. When the cleaning plate moves upward, the guide bar pushes the cleaning plate into the lifting box and the locking block fixes the cleaning plate away from the water screen plate. This prevents the cleaning plate from clogging subsequent impurities when it moves back. The pressing block can drive the dial in the locking box to move and pull the locking block out of the groove, thereby releasing the cleaning plate and making it re-contact with the water screen plate when it moves downward.
[0016] (2) The present invention can clean the filter cylinder by setting the spray chamber. At the same time, impurities will fall into the collection pipe. Simultaneously, by setting the internal teeth, the cleaning blades in the collection pipe can be rotated when the filter cylinder rotates, so that the cleaning blades push the impurities into the inertial chamber. Then, by the inertia of falling, the inertial plate in the inertial chamber is rotated, thereby realizing the rotation of the moving screw, which in turn drives the scraper to move and push the impurities to both sides of the collection chamber for collection, and prevents the impurities from clogging the filter plate.
[0017] (3) By setting up a pretreatment chamber, a filter cylinder, and a collection chamber, the present invention can achieve multiple filtrations of wastewater. At the same time, the cleaning plate in the pretreatment chamber can accelerate the filtration effect of wastewater and avoid the filtration of the water sieve plate. Furthermore, by setting up the collection chamber, the wastewater and impurities collected in the collection pipe can be separated again. By setting up the components in the pretreatment chamber and the filter cylinder, impurities can be cleaned without stopping the equipment, which improves the efficiency of wastewater filtration and avoids overloading of the filtration device.

Detailed Implementation
[0021] 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.
[0022] Please see Figures 1-14 As shown, this application provides a wastewater treatment and purification device for livestock farming, including a pretreatment chamber 1, and further comprising: Filtering mechanism 2 is located on one side of pretreatment chamber 1 and is connected to pretreatment chamber 1; The summarizing mechanism 3 is located below the filtering mechanism 2; Collection mechanism 4 is located inside the filtration mechanism 2; Wastewater is introduced into pretreatment chamber 1, where large impurities in the wastewater are coarsely filtered. Then, the coarsely filtered wastewater is fed into filtration mechanism 2 for fine filtration. After fine filtration, some impurities are introduced into collection mechanism 3 for secondary treatment. Finally, collection mechanism 4 is used to collect the impurities. During operation, wastewater from aquaculture enters the pretreatment chamber 1 through pipes. The pretreatment chamber 1 performs coarse filtration to separate large impurities from the wastewater. The separated wastewater then enters the filtration mechanism 2 through pipes for fine filtration. The finely filtered wastewater is discharged through pipes to await further treatment, while the filtered impurities enter the collection mechanism 3. The collection mechanism 3 separates the residual wastewater from the remaining impurities, which facilitates the separate treatment of impurities in the future and avoids the need for secondary separation due to a large amount of residual wastewater when treating impurities.
[0023] like Figures 2-8As shown, a water inlet pipe 11 is fixedly connected to the top of the pretreatment chamber 1; a water sieve plate 14 is fixedly connected to the side wall of the pretreatment chamber 1; the water sieve plate 14 is inclined; a drive chamber 13 is fixedly connected to the side wall of the pretreatment chamber 1; a drive screw 131 is rotatably connected inside the drive chamber 13; a lifting box 19 is threaded onto the drive screw 131; a telescopic spring 191 is fixedly connected inside the lifting box 19; multiple sets of telescopic springs 191 are provided; a cleaning plate 192 is fixedly connected to the end of the telescopic spring 191 away from the lifting box 19; a snap-fit box 195 is fixedly connected to the side wall of the lifting box 19; a snap-fit box 195 is fixedly connected inside the snap-fit box 195. A snap-fit spring 197 is attached to a snap-fit spring 197; a snap-fit block 196 is fixedly connected to the end of the snap-fit spring 197 away from the snap-fit box 195; the snap-fit block 196 is disposed through the snap-fit box 195; a dial 198 is fixedly connected to the end of the snap-fit block 196 away from the lifting box 19; a groove 1921 is opened on the side wall of the cleaning plate 192; two sets of snap-fit boxes 195 are provided, respectively disposed on both sides of the lifting box 19; guide blocks 193 are fixedly connected to the side walls of both sides of the cleaning plate 192; pulleys 194 are rotatably connected to the guide blocks 193; guide strips 16 are fixedly connected to both sides of the pretreatment chamber 1; pulleys 194 and guide strips 16 are in movable contact. During operation, wastewater enters the pretreatment chamber 1 through the inlet pipe 11, and then reaches the water screen plate 14 by inertia. The water screen plate 14 is inclined. After the wastewater reaches the water screen plate 14, it moves on the water screen plate 14 due to its falling inertia. At the same time, the water screen plate 14 intercepts impurities. The separated wastewater enters the pretreatment chamber 1 and is then transported to the filtration mechanism 2 for secondary filtration. Meanwhile, when the water screen plate 14 is filtering, the drive screw 131 is activated to rotate. When it rotates, it drives the lifting box 19 to move. The tilt angle of the lifting box 19 is consistent with that of the water sieve plate 14. When the lifting box 19 moves, it will drive the cleaning plate 192 to move on the water sieve plate 14 to clean impurities on the water sieve plate 14 and prevent impurities from clogging the water sieve plate 14. In the initial state, the cleaning plate 192 and the lifting box 19 are above the water sieve plate 14, that is, at the high point of the pretreatment chamber 1. When working, it will drive the cleaning plate 192 to move downwards from the water sieve plate 14. At this time, the cleaning plate 192 is in contact with the surface of the water sieve plate 14, thereby achieving the cleaning effect. When the cleaning plate 192... As the cleaning plate 192 approaches the bottom of the pretreatment chamber 1, the pulleys 194 on both sides of the cleaning plate 192 will contact the guide bar 16. The guide bar 16 is inclined. After contact, the pulleys 194 and the guide block 193 will be limited by the guide bar 16 and move upward, thus inserting the cleaning plate 192 into the lifting box 19 and compressing the telescopic spring 191. As the cleaning plate 192 moves into the lifting box 19, the groove 1921 on the side wall of the cleaning plate 192 will gradually contact the locking block 196 and compress the locking block 196. After the groove 1921 is parallel to the locking block 196, the locking block 196 loses its compression and is rebounded by the locking spring 197 behind the locking block 196, which pushes the locking block 196 into the groove 1921 to fix the cleaning plate 192. At this time, it also reaches the end of the drive screw 131. The drive screw 131 is a bidirectional screw. After reaching the end, it will drive the lifting box 19 to move upward. When moving upward, the cleaning plate 192 does not abut against the water screen plate 14, so that it will not push the impurities on the water screen plate 14 upward, nor will it prevent the impurities from falling downward.
[0024] like Figures 2-9As shown, the pretreatment chamber 1 has a drive groove 17 and a limiting groove 18 on its side wall; a pressing block 171 is fixedly connected in the drive groove 17; a limiting block 199 is fixedly connected to the end of the lifting box 19 away from the drive screw 131; the limiting block 199 is slidably disposed in the limiting groove 18; a pulley 1981 is rotatably connected to the dial 198; the pulley 1981 and the pressing block 171 are in movable contact; a crushing shaft 12 is rotatably connected to the side wall of the pretreatment chamber 1; a crushing rod 121 is fixedly connected to the crushing shaft 12. Multiple sets of crushing rods 121 are provided; a waste discharge chamber 15 is fixedly connected to the bottom of the pretreatment chamber 1; a waste discharge blade 151 is rotatably installed inside the waste discharge chamber 15; a waste discharge motor 153 is fixedly connected to the side wall of the waste discharge chamber 15; the waste discharge blade 151 is driven by the waste discharge motor 153; a pulley 152 is rotatably connected to the side wall of the waste discharge chamber 15; the input end of the pulley 152 is fixedly connected to the output end of the waste discharge blade 151; a second pulley is rotatably connected to the side wall of the pretreatment chamber 1; the output end of the second pulley is fixedly connected to the input end of the crushing shaft 12. During operation, wastewater entering through the inlet pipe 11 flows to the water screen plate 14 for filtration. Impurities trapped by the water screen plate 14 flow into the lower waste discharge chamber 15, driving the waste discharge blades 151 in the waste discharge chamber 15 to rotate. The waste discharge blades 151 then discharge the impurities out of the waste discharge chamber 15. Simultaneously, the rotation of the waste discharge blades 151 drives the external pulley 152 to rotate, which in turn drives the pulley 2 via a belt, thereby driving the upper crushing shaft 12 to rotate. The rotation of the crushing shaft 12 drives the crushing rods 121 to rotate. When wastewater enters the pretreatment chamber 1, it first contacts the crushing rods 121. Under rotation, the crushing rods 121 strike the impurities in the wastewater, breaking down larger impurities for easier subsequent filtration. Meanwhile, the lifting box 19 is limited by a limiting block 199 at the other end during movement to prevent it from shifting. After the push bar 16 presses the cleaning plate 192 into the lifting box 19, the drive screw 131 will drive the lifting box 19 back to the top of the pretreatment chamber 1. The snap-fit box 195 is located in the drive grooves 17 on both sides. When the lifting box 19 moves upward, the dial 198 on the snap-fit box 195 will gradually contact the pressing block 171. The side of the pressing block 171 that contacts the dial 198 is inclined. After contact, the lifting box 19 continues to move. When moving, the pressing block 171 will drive the dial 198 away from the snap-fit box 195, that is, pull the snap-fit block 196 out of the groove 1921. After being pulled out, the telescopic spring 191 in the lifting box 19 rebounds, popping the cleaning plate 192 out of the lifting box 19 and making contact with the water sieve plate 14 again, and then cleaning is performed. At the same time, the dial 198 is provided with a pulley 1981, which can reduce the friction between the dial 198 and the pressing block 171.
[0025] like Figure 10 and Figure 11As shown, the filter mechanism 2 includes a filter base 21 and a filter cylinder 24; a limiting base 22 is fixedly connected inside the filter base 21; a limiting wheel 221 is rotatably connected inside the limiting base 22; a limiting disk 243 is fixedly connected to the filter cylinder 24; the limiting disk 243 is meshed with the limiting wheel 221; external teeth 242 are fixedly connected to the outer wall of the filter cylinder 24; a drive motor 23 is fixedly connected to the side wall of the filter base 21; a drive gear 231 is fixedly connected to the end of the drive motor 23; the drive gear 231 is located inside the filter base 21 and meshes with the external teeth 242; a connecting pipe 25 is fixedly connected to the side wall of the filter base 21; one end of the connecting pipe 25 away from the filter base 21 is rotatably connected to the filter cylinder 24 and is in communication with it; a feeding disk 244 is fixedly connected to the filter base 21; the feeding disk 244 is located at the end of the filter cylinder 24. During operation, the wastewater filtered by the water screen plate 14 enters the filter cylinder 24 through the pipe. Then, the filter cylinder 24 is driven to rotate by the drive gear 231. When the filter cylinder 24 rotates, it is limited and lifted by the limit wheel 221 and the limit plate 243. The filter cylinder 24 performs filtration when it rotates. The filtered wastewater enters the filter base 21, while the impurities remain in the filter cylinder 24. When the filter cylinder 24 rotates, the impurities will gradually move to the feed tray 244 and finally reach the feed tray 244. Then, the feed tray 244 will transport the impurities to the collection mechanism 3 below.
[0026] like Figure 14 As shown, the collection mechanism 4 includes a collection pipe 41 and an inertial chamber 45; a cleaning blade 42 is rotatably disposed inside the collection pipe 41; the cleaning blade 42 is located below the filter cylinder 24; an open chamber 43 is fixedly connected to the collection pipe 41; the open chamber 43 is located above the cleaning blade 42; a driven gear 44 is rotatably connected to the side wall of the collection pipe 41; an internal gear 241 is fixedly connected to the inner wall of the filter cylinder 24; the driven gear 44 meshes with the internal gear 241; a spray chamber 26 is disposed on the filter base 21; a partition 245 is fixedly connected to the inner wall of the filter cylinder 24; the partition 245 is made of rubber. During operation, the collection pipe 41 is located at the top of the filter cylinder 24. During filtration, some impurities will remain in the holes of the filter cylinder 24. At this time, the spray chamber 26 outside the filter cylinder 24 is activated to spray water onto the filter cylinder 24. The spray chamber 26 can be connected to the filter base 21 for wastewater recycling. Since the filter cylinder 24 is a fine filter, the recycled water will not clog the spray chamber 26. After the filter cylinder 24 is sprayed, the impurities in the holes will fall into the lower opening chamber 43 and then into the collection pipe 41. At the same time, when the filter cylinder 24 rotates, the internal teeth 241 will drive the driven gear 44 on one side of the collection pipe 41 to rotate, which in turn drives the cleaning blades 42 inside the collection pipe 41 to rotate. Thus, under the rotation of the cleaning blades 42, the impurities are transported out of the filter pipe. The baffle 245 can separate the impurities and prevent them from clumping together.
[0027] like Figure 12 and Figure 13 As shown, the summarizing mechanism 3 includes a summarizing bin 31; a feeding tray 244 is located above the summarizing bin 31; an inertial bin 45 is fixedly connected to the top of the summarizing bin 31; a moving screw 33 is rotatably connected to the side wall of the summarizing bin 31; a scraper 34 is threaded onto the moving screw 33; a filter plate 32 is fixedly connected inside the summarizing bin 31; and the scraper 34 abuts against the surface of the filter plate 32. During operation, the impurities entering the feeding tray 244 and the collection pipe 41 will eventually reach the collection bin 31 for final wastewater separation. After reaching the collection bin 31, the moving screw 33 is started to rotate, which drives the scraper 34 to move on the filter plate 32. On the one hand, the impurities trapped on the filter plate 32 are cleaned and collected, and on the other hand, the impurities are prevented from clogging the filter plate 32.
[0028] like Figure 13 As shown, an inertia shaft 453 is rotatably connected inside the inertia chamber 45; an inertia plate 452 is fixedly connected to the inertia shaft 453; a pulley 3 451 is rotatably connected to the outer wall of the inertia chamber 45; the input end of the pulley 3 451 is fixedly connected to the output end of the inertia shaft 453; a pulley 4 331 is rotatably connected to the side wall of the summarization chamber 31; the output end of the pulley 4 331 is fixedly connected to the input end of the moving lead screw 33. During operation, impurities and wastewater will fall into the inertial chamber 45 through the collection pipe 41. Then, the inertia of the falling will drive the inertial plate 452 to rotate, thereby driving the external pulley 3 451 to rotate. Then, the belt will drive the pulley 4 331 to rotate, thus realizing the movement of the scraper 34.
[0029] like Figure 1 As shown, a water outlet pipe 211 is fixedly connected to the bottom of the filter base 21; a water outlet pipe 35 is fixedly connected to the bottom of the collection chamber 31; the water outlet pipe 211 and the water outlet pipe 35 are connected. During operation, the wastewater filtered by the filter cartridge 24 and filter plate 32 is discharged through the outlet pipe 211 and the outlet pipe 35.
[0030] Please see Figures 1-14 As shown, this application provides a wastewater treatment and purification method for livestock farming, comprising the following steps: S1, wastewater is injected into the pretreatment chamber 1 through the inlet pipe 11, and then the impurities in the wastewater are crushed by the crushing rod 121, so that the water screen plate 14 below can perform coarse filtration. The filtered wastewater enters the filter cylinder 24 through the pipe, while the impurities flow into the waste discharge chamber 15 for discharge. S2, after coarse filtration, the wastewater enters the filter cylinder 24 and drives the filter cylinder 24 to rotate. When rotating, the wastewater will be finely filtered. The filtered wastewater will then flow into the outlet pipe 211 and be discharged. The impurities will remain in the filter cylinder 24 and then be discharged into the collection bin 31. S3, after the impurities in the filter cartridge 24 enter the collection chamber 31, they undergo final filtration in the collection chamber 31 to separate the impurities from the wastewater, and are finally discharged through the outlet pipe 35 for further treatment. During operation, wastewater is injected into the pretreatment chamber 1 through the inlet pipe 11. Then, the impurities in the wastewater are crushed by the crushing rod 121, which facilitates coarse filtration by the water screen plate 14 below. The filtered wastewater enters the filter cylinder 24 through the pipe, while the impurities flow into the waste discharge chamber 15 for discharge. After coarse filtration, the wastewater enters the filter cylinder 24 and drives the filter cylinder 24 to rotate. During rotation, the wastewater undergoes fine filtration. Subsequently, the filtered wastewater flows into the outlet pipe 211 for discharge, while the impurities remain in the filter cylinder 24 and are then discharged into the collection chamber 31. After the impurities in the filter cylinder 24 enter the collection chamber 31, they undergo final filtration in the collection chamber 31 to separate the impurities from the wastewater.
