Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and specifically to a biological filtration equipment device for sewage treatment. Background Art

[0002] Pesticide residue refers to the phenomenon that after pesticides are applied in agricultural production, a part of the pesticides directly or indirectly remain in grains, vegetables, fruits, as well as soil and water bodies. In order to improve the application effect and efficiency of pesticides and reduce the use of pesticides, domestic and foreign scholars have developed spraying equipment such as air-assisted sprayers for standardized pesticide application. After the spraying operation is completed, these equipment generally need to be cleaned with clean water inside the machine box to remove the remaining pesticides in the machine for the next use. However, after cleaning, there are no treatment measures for the washing water containing pesticide residues, which is directly discharged into farmland soil or nearby water bodies, causing environmental pollution problems and posing certain potential safety hazards.

[0003] Chinese Patent CN215924655U includes a preliminary filtration mechanism, a cooling precipitation mechanism, and a mixing treatment mechanism. The preliminary filtration mechanism is connected to the cooling precipitation mechanism through a first feed pipe, and the cooling precipitation mechanism is connected to the mixing treatment mechanism through a second feed pipe. Delivery pumps are provided in the pipelines of the first feed pipe and the second feed pipe.

[0004] For this utility model and the existing agricultural residue sewage filtration equipment in the prior art, after putting the filtration raw materials into the filter, the staff cannot turn over the raw materials at regular intervals, resulting in some raw materials not being able to disperse during the long-term sewage filtration, and the filtration effect cannot be fully exerted, affecting the filtration effect of agricultural residue sewage. At the same time, when the agricultural residue sewage flows to the subsequent processing equipment after filtration, because the staff cannot dredge the water pipe when the filter is working, it is easy for the water pipe to be blocked by the leaked raw materials, thereby reducing the flow rate of agricultural residue sewage, and the processing efficiency is significantly reduced. Moreover, after filtering the sewage, the staff needs to manually dredge the water pipe, which increases the workload and wastes unnecessary human resources.

[0005] For the problems in the related art, no effective solutions have been proposed yet. Summary of the Invention

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention provides a biological filtration equipment for sewage treatment, which has the following beneficial effects:

[0019] 1. This type of biological filtration equipment for sewage treatment starts the motor, and after the output end of the motor rotates, it drives the first reciprocating screw and the second reciprocating screw to rotate in opposite directions through the rotating shaft, the main bevel gear and the auxiliary bevel gear, and then makes the two sliders move toward or away from each other. When the two sliders move toward each other, the distance between the sliders is reduced, and the abutment plate is driven to move vertically upward. When the abutment plate moves, it can hit the filter gauze, so that the filter gauze can briefly vibrate the filter material on the top, and the filter material on the top of the filter gauze can be repeatedly vibrated, thereby improving the dispersion effect of the filter material and further improving the filtering effect of agricultural wastewater.

[0020] 2. This type of biological filtration equipment for sewage treatment drives the driving gear to rotate through the first reciprocating screw, and the driving gear drives the driven gear to rotate by engaging with the driven gear. After the driven gear rotates, the transmission rod, guide plate and force plate drive the rotating rod to rotate, and when the rotating rod rotates, it drives the cleaning plate to rotate. After the cleaning plate rotates, it can clean the filter screen on one side of the water pipe, and then clean the residue on the surface of the filter screen when the raw materials are broken up, preventing the filtered raw materials from entering the water pipe and affecting the circulation speed of agricultural wastewater, thereby improving the filtration efficiency of agricultural wastewater.

[0021] 3. This type of biological filtration equipment for sewage treatment has a guide plate that no longer contacts the force plate and the torsion spring releases pressure, causing the rotating rod to rotate in the opposite direction. At the same time, the transmission rod can again make the guide plate press against the force plate after rotating one circle, so that the torsion spring is continuously squeezed and the pressure is released, thereby causing the cleaning plate to rotate back and forth in a small range, thereby improving the cleaning effect of the filter screen, eliminating the need for manual cleaning, and saving manpower.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0034] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a biological filtration equipment for sewage treatment.

[0035] Please refer to Figures 1-9, A biological filtration equipment for sewage treatment, including a filter 1. Inside several filters 1, a bearing plate 2 is fixedly installed, and a filtration component 3 is provided. On the top of the bearing plate 2, a driving component 4 and a position adjustment component 5 are arranged. The driving component 4 includes a motor 401, and the position adjustment component 5 includes a first reciprocating screw rod 501, a second reciprocating screw rod 502, a slider 503 and a pressing plate 504. The motor 401 can drive the first reciprocating screw rod 501 and the second reciprocating screw rod 502 to rotate in opposite directions. Both the first reciprocating screw rod 501 and the second reciprocating screw rod 502 can drive the slider 503 to reciprocate horizontally. When the two sliders 503 move, they can drive the pressing plate 504 to reciprocate vertically. The filtration component 3 includes a filtration gauze 301. When the pressing plate 504 moves, it can intermittently push the filtration gauze 301 to move vertically. Inside the filter 1, a cleaning component 6 is provided. The cleaning component 6 includes a rotating rod 601, a torsion spring 602 and a cleaning plate 603. A transmission component is arranged between the rotating rod 601 and the first reciprocating screw rod 501. The first reciprocating screw rod 501 drives the rotating rod 601 to rotate through the transmission component. The torsion spring 602 can drive the rotating rod 601 to reset. Between several filters 1, a water pipe 103 is connected. A filter screen is arranged at the water inlet end of the water pipe 103. The transmission component includes a transmission rod 701, a guide plate 702 and a stress plate 703.

[0036] When it is necessary to treat agricultural residue sewage, the staff use a straw crusher to crush the dried straw into powder. Taking straw, soil and matrix as raw materials, after mixing evenly according to a certain ratio, they are successively filled into a single filter 1 and stored on the top of several filter plates 304 and the filtration gauze 301. Then, the agricultural residue sewage is pumped into the uppermost filter 1. At this time, the motor 401 is started. When the output end of the motor 401 rotates, it drives the first reciprocating screw rod 501 and the second reciprocating screw rod 502 to rotate in opposite directions. When the first reciprocating screw rod 501 and the second reciprocating screw rod 502 rotate, they can drive the two sliders 503 to move towards or away from each other. When the two sliders 503 move towards each other, the distance between the sliders 503 is reduced, and the pressing plate 504 is driven to move vertically upward. When the pressing plate 504 moves, it can push against the filtration gauze 301, so that the filtration gauze 301 can briefly vibrate the filtration raw materials on the top. When the two sliders 503 move away from each other, the pressing plate 504 no longer presses against the filtration gauze 301 after moving, so that the filtration gauze 301 moves downward after losing the force. Then, through the reciprocating movement of the two sliders 503, the filtration raw materials on the top of the filtration gauze 301 can be repeatedly vibrated, improving the dispersion effect of the filtration raw materials and further improving the filtration effect of the agricultural residue sewage;

[0037] When the first reciprocating lead screw 501 rotates, it can also drive the rotating rod 601 to rotate through the transmission component. When the rotating rod 601 rotates, it squeezes the torsion spring 602 and drives the cleaning plate 603 to rotate. After the cleaning plate 603 rotates, it can clean the filter screen on one side of the water pipe 103, preventing the filtered raw materials from entering the water pipe 103 and affecting the flow rate of the agricultural residue sewage, thereby improving the filtering efficiency of the agricultural residue sewage. When the transmission component is not cooperating with the rotating rod 601, the torsion spring 602 releases pressure, thereby driving the rotating rod 601 to rotate in the reverse direction. At the same time, after the transmission rod 701 rotates one circle, it can again make the guiding plate 702 abut against the stress plate 703, causing the torsion spring 602 to be continuously squeezed and release pressure, thereby causing the cleaning plate 603 to rotate reciprocally in a small amplitude, thereby improving the cleaning effect on the filter screen.

[0038] In one embodiment, the driving component 4 further includes a rotating shaft 402, a main bevel gear 403 and a sub-bevel gear 404. The mounting end of the motor 401 is fixedly connected to the bearing plate 2. One end of the rotating shaft 402 is fixedly connected to the output end of the motor 401, and the other end is fixedly connected to the main bevel gear 403. The two sub-bevel gears 404 are respectively fixedly connected to the first reciprocating lead screw 501 and the second reciprocating lead screw 502, and are meshed with the main bevel gear 403.

[0039] When the output end of the motor 401 rotates, it drives the rotating shaft 402 to rotate. After the rotating shaft 402 rotates, it drives the main bevel gear 403 to rotate. When the main bevel gear 403 rotates, it drives the first reciprocating lead screw 501 and the second reciprocating lead screw 502 to rotate relatively in the opposite direction through the two sub-bevel gears 404. The transmission effect can quickly move the two sliders 503.

[0040] In one embodiment, the position adjusting component 5 further includes a support leg 505 and a guide rail 506. The support leg 505 is fixedly connected to the top of the bearing plate 2. The guide rail 506 is fixedly connected to the support leg 505. The two sliders 503 are slidably engaged with the guide rail 506 and are respectively threadedly connected to the first reciprocating lead screw 501 and the second reciprocating lead screw 502. One ends of the first reciprocating lead screw 501 and the second reciprocating lead screw 502 are respectively rotatably connected to the inner walls of the two support legs 505.

[0041] When the first reciprocating lead screw 501 and the second reciprocating lead screw 502 rotate, the guide rail 506 can limit the sliders 503, so that the sliders 503 can move horizontally. With the limiting effect, the support leg 505 can improve the fixing effect of the guide rail 506.

[0042] In one embodiment, the position adjusting component 5 further includes a connecting block 507 and a connecting rod 508. The connecting block 507 is fixedly connected to the bottom of the abutting plate 504. One end of the connecting rod 508 is hinged to the connecting block 507, and the other end is hinged to the slider 503.

[0043] When the two sliders 503 move towards each other, the distance between the sliders 503 is reduced, and they are hinged through the connecting rod 508 and the connecting block 507, driving the abutting plate 504 to move vertically upward. When the two sliders 503 move away from each other, the two sliders 503 can drive the abutting plate 504 to move vertically downward.

[0044] In one embodiment, the transmission assembly includes a transmission rod 701, a guide plate 702, and a force-bearing plate 703. One end of both the transmission rod 701 and the rotating rod 601 is rotatably connected to the filter 1. The guide plate 702 is sleeved on the transmission rod 701, and both the force-bearing plate 703 and the cleaning plate 603 are sleeved on the rotating rod 601. The guide plate 702 cooperates with the force-bearing plate 703. A torsion spring 602 is arranged on the rotating rod 601 and one end thereof is connected to the force-bearing plate 703.

[0045] When the first reciprocating lead screw 501 rotates, it can drive the transmission rod 701 to rotate. When the transmission rod 701 rotates, it drives the guide plate 702 to rotate. When the guide plate 702 rotates, it can abut against the force-bearing plate 703, and drives the rotating rod 601 to rotate through the force-bearing plate 703. When the rotating rod 601 rotates, it squeezes the torsion spring 602 and drives the cleaning plate 603 to rotate. After the cleaning plate 603 rotates, it can clean the filter screen on one side of the water pipe 103. When the guide plate 702 no longer contacts the force-bearing plate 703, the torsion spring 602 releases the pressure, thereby driving the rotating rod 601 to rotate in the reverse direction. At the same time, after the transmission rod 701 rotates one circle, it can again make the guide plate 702 abut against the force-bearing plate 703, causing the torsion spring 602 to be continuously squeezed and release pressure, thereby causing the cleaning plate 603 to rotate reciprocally in a small amplitude, improving the cleaning effect on the filter screen.

[0046] In one embodiment, the transmission assembly further includes a driven shaft 704, a driving gear 705, a driven gear 706, and a belt 707. One end of the driven shaft 704 is rotatably connected to the filter 1. The driving gear 705 is sleeved on the first reciprocating lead screw 501. The driven gear 706 is sleeved on the driven shaft 704 and meshes with the driving gear 705. The driven gear 706 is sleeved on both the transmission rod 701 and the driven shaft 704.

[0047] When the first reciprocating lead screw 501 rotates, it can also drive the driving gear 705 to rotate. The driving gear 705 drives the driven gear 706 to rotate by meshing with the driven gear 706. After the driven gear 706 rotates, it drives the driven shaft 704 to rotate. When the driven shaft 704 rotates, it drives the transmission rod 701 to rotate through the belt 707.

[0048] In one embodiment, the filtering component 3 further includes a fixing plate 302, a sliding rod 303 and a filtering plate 304. A plurality of fixing plates 302 are fixedly connected to the filter 1. Both ends of the sliding rod 303 are fixedly connected to the fixing plate 302. The filtering gauze 301 is sleeved on a plurality of sliding rods 303 and is in sliding fit with the sliding rods 303. A plurality of filtering plates 304 are all fixedly connected to the filter 1.

[0049] The fixing plate 302 can limit the moving amount of the filtering gauze 301, and at the same time, the sliding rod 303 can play a guiding role.

[0050] In one embodiment, a water inlet pipe 101 is connected to the top of one of the filters 1 in a communicating manner. Atomizing nozzles 102 are fixedly installed at the other ends of the water inlet pipe 101 and the water through pipe 103. One end of the lowermost filter 1 is connected to a water outlet pipe in a communicating manner, and a filter screen is installed at one end of the water outlet pipe.

[0051] The atomizing nozzle 102 is internally provided with a motor. When the agricultural residue sewage flows through the water inlet pipe 101 and the water through pipe 103, the agricultural residue sewage can be dispersed by the atomizing nozzle 102, so that the agricultural residue sewage can be better filtered, improving the filtering effect. The other end of the water inlet pipe 101 is connected to a small photovoltaic water pump, which is not shown in the figure;

[0052] By arranging a plurality of filters 1, the agricultural residue sewage can be filtered multiple times, improving the filtering effect. Moreover, the filters 1 in the figure are only for display, and the form can be adjusted according to actual use, such as a cube. The material of the filter screen is PTFE (polytetrafluoroethylene) fiber. The surface tension of polytetrafluoroethylene is very low, and it has good non-stickiness and water repellency, which can ensure that the purified agricultural residue sewage can be discharged without being affected during long-term use, improving the filtering effect.

[0053] Working principle:

[0054] When it is necessary to treat agricultural wastewater, the staff will use a straw crusher to crush the dried straw into powder, and use straw, soil and matrix as raw materials. After mixing evenly according to a certain ratio (1:1:1), they are loaded into a single filter 1 in sequence and stored on top of several filter plates 304 and filter gauze 301. Then, the agricultural wastewater is pumped into the top filter 1 through the water inlet pipe 101. The agricultural wastewater entering the filter 1 can be dispersed by the atomizing nozzle 102, so that the agricultural wastewater is better filtered and the filtering effect is improved. At this time, the motor 401 is started, and when the output end of the motor 401 rotates, it drives the rotating shaft 402 to rotate. After the rotating shaft 402 rotates, it drives the main bevel gear 403 to rotate. When the main bevel gear 403 rotates, it drives the first reciprocating screw 501 and the second reciprocating screw 502 to rotate in opposite directions through the two sub-bevel gears 404. When the two sliders 503 move toward each other, the distance between the sliders 503 is reduced, and the connecting rod 508 and the connecting block 507 are hinged to drive the support plate 504 to move vertically upward. When the support plate 504 moves, it can hit the filter gauze 301, so that the filter gauze 301 can briefly vibrate the filter material on the top. When the two sliders 503 move away from each other, the support plate 504 no longer presses against the filter gauze 301 after moving, so that the filter gauze 301 loses the force and moves downward under the action of the slide rod 303. Then, the reciprocating movement of the two sliders 503 can make the filter material on the top of the filter gauze 301 repeatedly vibrate, thereby improving the dispersion effect of the filter material and further improving the filtering effect of agricultural wastewater.

[0055] When the first reciprocating screw 501 rotates, it can also drive the driving gear 705 to rotate. The driving gear 705 drives the driven gear 706 to rotate by meshing with the driven gear 706. After the driven gear 706 rotates, it drives the driven shaft 704 to rotate. When the driven shaft 704 rotates, it drives the transmission rod 701 to rotate through the belt 707. When the transmission rod 701 rotates, it drives the guide plate 702 to rotate. When the guide plate 702 rotates, it can resist the force plate 703 and drive the rotating rod 601 to rotate through the force plate 703. When the rotating rod 601 rotates, it squeezes the torsion spring 602 and drives the cleaning plate 603 to rotate. After the cleaning plate 603 rotates, it can clean the filter screen on one side of the water pipe 103 to prevent the filtered raw materials from entering the water pipe 103 and affecting the circulation speed of the agricultural wastewater, thereby improving the filtration efficiency of the agricultural wastewater. When the guide plate 702 is no longer in contact with the force plate 703, the torsion spring 602 releases the pressure, thereby driving the rotating rod 601 to rotate in the opposite direction. At the same time, the transmission rod 701 can make the guide plate 702 press against the force plate 703 again after rotating one circle, so that the torsion spring 602 is continuously squeezed and the pressure is released, thereby making the cleaning plate 603 rotate back and forth slightly, thereby improving the cleaning effect of the filter screen.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
