Description

Technical Field

[0001] The invention belongs to the technical field of sewage filtration, in particular to a sewage filtration device for a material washing machine. Background Art

[0002] After washing the materials, the material washing machine will filter the washed sewage through a filter device, and then send it back for recycling through a water pump to ensure the rational use of water resources. Traditional sewage filtering devices all filter through a filter. After several rounds of filtration, the filtering efficiency of the filter will drop significantly. It is usually necessary to manually clean the impurities separated from the filter. This method is extremely time-consuming when the washing machine is in continuous operation, which reduces the working efficiency of the material washing machine. At the same time, when the sewage is discharged into the filtering device, if the sewage contains a lot of impurities, a large amount of impurities will cause the connection between the material washing machine and the filtering device to be blocked, thereby hindering the discharge of sewage. Due to the turbidity of the sewage, manual dredging also requires finding a drain outlet, which further reduces the working efficiency of the material washing machine and the filtering efficiency of the filtering device.

[0003] Therefore, a sewage filtering device for a material washing machine is proposed to solve the above problems. Summary of the invention

[0012] Preferably, the outer sleeve of the connecting frame is provided with a sealing ring capable of closing the water outlet, and the outer fixed sleeve of the sealing ring is provided with a floating ring.

[0013] Preferably, it also includes a water supply mechanism, which includes a fixed cylinder, which is installed in the filter box and located below the filter disc.

[0014] Preferably, the top of the piston is fixedly connected with a curved pipe that can be raised and lowered in the filter box, the other end of the curved pipe is connected with a connecting pipe, and the other end of the connecting pipe is connected with the cone block.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention provides a filter disc and a scraper. When sewage is discharged into the filter box, the control motor drives the driving gear to rotate, so that the driving gear meshes and drives the driven gear 1 to rotate. At the same time, the driven gear 1 drives the movable shaft and the filter disc to rotate. At this time, the sewage entering the filter box will be filtered by the filter disc for impurities and then flow to the lower part of the filter box. Due to the rotation of the filter disc, the screen surface on the filter disc can be reasonably utilized to improve the efficiency of sewage filtration. Due to the rotation of the driven gear 1, it can mesh and drive the driven gear 2, the fixed block and the scraper to rotate together, and the impurities separated on the fixed block are scraped into the collection box by the scraper. When the scraper rotates to the point where it is aligned with the round head block When abutting, as the fixed block continues to rotate, the scraper can be flipped over by the round head block. At this time, the rotation of the scraper shaft can drive the arc block to extend into the interior of the mounting block and compress the arc spring. After the scraper is separated from the round head block, due to the elastic recovery effect of the arc spring, the scraper can be quickly reset by pushing the arc block, and under the inertia of the scraper's rapid reset, the impurities attached to the scraper that cannot fall naturally are shaken off into the collection box. This design can improve the filtering effect of the filtering device. At the same time, the rotation of the filter plate and the scraping of the scraper can ensure the cleanliness of the filter plate screen surface and avoid clogging of the filter plate screen surface during filtration.

[0017] The present invention arranges a cone block and a support frame. When the movable shaft rotates, the cone gear one can be driven to rotate together. At the same time, the meshing of the cone gear one can drive the cone gear two and the movable disk to rotate. Due to the rotation of the movable disk, the lifting block can be driven by the circular shaft to perform reciprocating lifting and lowering motion in the movable cavity. Due to the movement of the lifting block, the limit rod, the connecting frame and the cone block can be driven to perform reciprocating lifting and lowering motion together. Due to the reciprocating lifting and lowering of the cone block, the impurities remaining at the connecting pipe opening of the filter box and the material washing mechanism can be reciprocated and squeezed through the conical surface of the cone block. The impurities blocked at the connecting pipe opening of the filter box and the material washing mechanism can be further tamped through by the reciprocating lifting and lowering of the support frame, thereby avoiding a large amount of impurities from clogging the connecting part of the material washing mechanism and the filter box, thereby improving the discharge efficiency of sewage. At the same time, there is no need to find a drain outlet when manually dredging, thereby improving the working efficiency of the material washing mechanism and the filtering mechanism.

[0018] The present invention provides a round block and a water outlet hole. Under the repeated lifting and lowering action of the cone block, the connecting pipe, the bent pipe and the piston can be driven to lift and lower back and forth in the fixed cylinder. Due to the rising of the piston, the second one-way valve can be opened, and the filtered water in the filter box can be drawn into the fixed cylinder. Due to the descending of the piston, the first one-way valve can be opened, so that the water in the fixed cylinder can pass through the piston and enter the inside of the bent pipe. With the reciprocating lifting and lowering of the piston, the filtered water can be pumped into the cone block through the bent pipe and the connecting pipe, and the round block can be pushed to rise. At this time, the straight spring is stretched, and water can be pumped into the cone block with the repeated lifting and lowering of the cone block. When the connecting frame rises, if the height of the liquid level in the material washing mechanism is higher than the floating ring, the floating ring can start to move under the action of buoyancy. Finally, the sealing ring is driven to seal the water outlet. If the height of the liquid level inside the material washing mechanism drops below the floating ring, it can be determined that the sewage inside the material washing mechanism is about to be discharged. At this time, the motor stops running, and the cone block keeps the connection open. Under the gravity of the floating ring and the sealing ring, the cone block drops with the liquid level and releases the sealing ring from closing the water outlet. Under the elastic recovery effect of the straight spring, the round block can be driven to move downward, and the filtered water inside the cone block is sprayed out through the water outlet to flush the impurities remaining on the bottom of the inner cavity of the material washing mechanism, and flush the impurities remaining on the bottom of the inner cavity of the material washing mechanism into the interior of the filter box, thereby ensuring the cleanliness of the bottom of the inner cavity of the filter box and preventing the residual impurities from being mixed into the next round of material washing operations.

DETAILED DESCRIPTION

[0032] 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.

[0033] like Figures 1 to 12 As shown, the present invention provides a sewage filtering device for a material washing machine, comprising a material washing mechanism 1 and a filtering mechanism 2;

[0034] The filtering mechanism 2 is arranged below the material washing mechanism 1 and is communicated with the interior of the material washing mechanism 1;

[0035] The filter mechanism 2 includes a filter box 21, which is movably installed below the material washing mechanism 1 and can be communicated with the water outlet of the material washing mechanism 1. A movable shaft 22 is movably installed inside the filter box 21, and a filter disc 23 is fixedly sleeved on the outside of the movable shaft 22. A cavity 24 is opened at the bottom of the filter box 21. The bottom end of the movable shaft 22 extends into the cavity 24 and is fixedly sleeved with a driven gear 25. A driving gear 29 that can be driven by a motor is movably installed in the cavity 24, and the driving gear 29 is meshed with the driven gear 25. A driven gear 26 that can mesh with the driven gear 25 is movably installed inside the cavity 24. A fixed block 27 is coaxially connected to the driven gear 26, and six scrapers 28 are movably installed on the outside of the fixed block 27. The outside of the rotating shaft of the scraper 28 is connected to an arc block 212 located inside the fixed block 27. The fixed block 27 is surrounded by mounting blocks 211 with the same number as the arc blocks 212. The arc blocks 212 are movably sleeved inside the mounting block 211. An arc spring 213 is connected to one side of the arc block 212, and the other end of the arc spring 213 is connected to the inner wall of the mounting block 211. Five round head blocks 210 are connected above the inner wall of the filter box 21, and a collecting box 214 that can be pulled out of the filter box 21 is movably sleeved at the rear of the filter box 21.

[0036] Adopting the above scheme: when sewage is discharged into the filter box 21, the control motor drives the driving gear 29 to rotate, so that the driving gear 29 meshes and drives the driven gear 1 25 to rotate, and at the same time, the driven gear 1 25 drives the movable shaft 22 and the filter plate 23 to rotate. At this time, the sewage entering the filter box 21 will be filtered by the filter plate 23 for impurities and then flow to the lower part of the filter box 21. Due to the rotation of the filter plate 23, the screen surface on the filter plate 23 can be reasonably utilized to improve the efficiency of sewage filtration. Due to the rotation of the driven gear 1 25, it can mesh and drive the driven gear 2 26, the fixed block 27 and the scraper 28 to rotate together, and the impurities separated on the fixed block 27 are scraped to the collection area by the scraper 28. In the box 214, when the scraper 28 rotates to abut against the round head block 210, as the fixed block 27 continues to rotate, the scraper 28 can be flipped over by the round head block 210. At this time, the rotation of the scraper 28 shaft can drive the arc block 212 to extend into the interior of the mounting block 211 and compress the arc spring 213. After the scraper 28 is separated from the round head block 210, due to the elastic recovery effect of the arc spring 213, the scraper 28 can be quickly reset by pushing the arc block 212, and under the inertia of the scraper 28 quickly resetting, the impurities attached to the scraper 28 that cannot fall naturally are shaken off into the collection box 214, thereby improving the filtering effect of the filtering device.

[0037] like Figure 7 and Fig. 9As shown, it also includes a clearing mechanism 3, which includes a movable chamber 31 and a cone block 39. The movable chamber 31 is opened above the inside of the filter box 21, and a bevel gear 1 32 coaxial with the movable shaft 22 is movably installed in the movable chamber 31. A bevel gear 2 33 that can mesh with the bevel gear 1 32 is movably installed in the movable chamber 31, and a movable disk 34 coaxial with the bevel gear 2 33 is movably installed in the movable chamber 31.

[0038] With the above solution, when the movable shaft 22 rotates, the bevel gear 1 32 can be driven to rotate together, and the bevel gear 2 33 and the movable disk 34 can be driven to rotate through the meshing of the bevel gear 1 32, thereby driving the movable disk 34.

[0039] like Figure 7 and Figure 8 As shown, the conical block 39 is plugged in the connection between the filter box 21 and the material washing mechanism 1 and can block the connection between the filter box 21 and the material washing mechanism 1. The bottom of the conical block 39 is connected to a support frame 315 located at the connecting pipe opening between the material washing mechanism 1 and the filter box 21, and the outside of the conical block 39 is connected to a connecting frame 38 located in the material washing mechanism 1.

[0040] By adopting the above scheme, when the cone block 39 is lifted and lowered back and forth, the impurities remaining at the connecting pipe opening between the filter box 21 and the material washing mechanism 1 can be squeezed and reciprocated by the cone surface of the cone block 39, and the impurities blocked at the connecting pipe opening between the filter box 21 and the material washing mechanism 1 can be further tamped through by the reciprocating lifting and lowering of the support frame 315, thereby avoiding a large amount of impurities from clogging the connecting part between the material washing mechanism 1 and the filter box 21.

[0041] like Figures 7 to 12 As shown, a lifting block 36 is slidably installed in the movable cavity 31, and a circular shaft 35 that can move in the lifting block 36 is connected to the side of the movable disk 34 facing the lifting block 36. A limiting rod 37 is connected to the lifting block 36. The limiting rod 37 passes through the filter box 21 and extends into the material washing mechanism 1 and is connected to the connecting frame 38.

[0042] By adopting the above scheme, due to the rotation of the movable disk 34, the lifting block 36 can be driven by the circular shaft 35 to perform reciprocating lifting motion in the movable cavity 31. Due to the movement of the lifting block 36, the limit rod 37, the connecting frame 38 and the cone block 39 can be driven to perform reciprocating lifting motion together, thereby driving the cone block 39 to perform reciprocating lifting motion.

[0043] like Figure 7 and Figure 8 As shown, a round block 310 is sleeved inside the cone block 39 , a straight spring 314 is connected to the bottom of the round block 310 , and the other end of the straight spring 314 is connected to the inner wall of the cone block 39 , and a plurality of water outlet holes 311 are opened around the inside of the round block 310 .

[0044] By adopting the above solution, when water is pumped into the cone block 39 , the round block 310 can be pushed upward, and the straight spring 314 is stretched, so that the round block 310 accumulates force and applies pressure to the water inside the cone block 39 .

[0045] like Figure 7 and Figure 8 As shown, the outer sleeve of the connecting frame 38 is provided with a sealing ring 312 capable of closing the water outlet 311 , and the outer fixed sleeve of the sealing ring 312 is provided with a floating ring 313 .

[0046] With the above solution, when the connecting frame 38 rises, if the height of the liquid level inside the material washing mechanism 1 is higher than the float 313, the float 313 can always drive the sealing ring 312 to seal the water outlet 311 under the action of buoyancy. If the height of the liquid level inside the material washing mechanism 1 drops below the float 313, it can be determined that the sewage inside the material washing mechanism 1 is about to be discharged.

[0047] like Figure 7 , Figure 8 and Fig.10 As shown, it also includes a water supply mechanism 4, which includes a fixed cylinder 41. The fixed cylinder 41 is installed in the filter box 21 and is located below the filter disc 23. A piston 44 is sleeved in the fixed cylinder 41, and a one-way valve 1 45 is provided in the piston 44. A one-way valve 2 46 is provided at the bottom end of the fixed cylinder 41.

[0048] By adopting the above scheme, under the repeated lifting and lowering action of the cone block 39, the connecting pipe 43, the bent pipe 42 and the piston 44 can be driven to lift and lower back and forth in the fixed cylinder 41. Due to the rising of the piston 44, the one-way valve 2 46 can be opened, and the filtered water inside the filter box 21 can be drawn into the fixed cylinder 41. Due to the descent of the piston 44, the one-way valve 1 45 can be opened, so that the water in the fixed cylinder 41 can pass through the piston 44 and enter the inside of the bent pipe 42.

[0049] like Figure 7 , Figure 8 and Fig.10 As shown, the top of the piston 44 is fixedly connected to a curved pipe 42 that can be raised and lowered in the filter box 21 , the other end of the curved pipe 42 is connected to a connecting pipe 43 , and the other end of the connecting pipe 43 is connected to the cone block 39 .

[0050] By adopting the above scheme, as the piston 44 reciprocates and rises, the filtered water can enter the curved pipe 42 through the piston 44 and then be pumped into the cone block 39 through the curved pipe 42 and the connecting pipe 43, thereby achieving a water pumping effect in the cone block 39.

[0051] The working principle and use process of the present invention:

[0052] When the sewage in the material washing mechanism 1 needs to be discharged, the control motor drives the driving gear 29 to rotate, so that the driving gear 29 meshes and drives the driven gear 1 25 to rotate, and at the same time, the driven gear 1 25 drives the movable shaft 22 and the filter disc 23 to rotate. At this time, the water in the material washing mechanism 1 will enter the filter box 21, and after the impurities are filtered by the filter disc 23, it will flow to the lower part of the filter box 21. Due to the rotation of the filter disc 23, the screen surface on the filter disc 23 can be reasonably used to improve the efficiency of sewage filtration. Due to the rotation of the driven gear 1 25, it can mesh and drive the driven gear 2 26, the fixed block 27 and the scraper 28 to rotate together, and the separated impurities on the fixed block 27 can be removed by the scraper 28. The impurities are scraped into the collection box 214. When the scraper 28 rotates to abut against the round head block 210, as the fixed block 27 continues to rotate, the scraper 28 can be flipped over by the round head block 210. At this time, the rotation of the scraper 28 shaft can drive the arc block 212 to extend into the interior of the mounting block 211 and compress the arc spring 213. After the scraper 28 is separated from the round head block 210, due to the elastic recovery effect of the arc spring 213, the scraper 28 can be quickly reset by pushing the arc block 212, and under the inertia of the scraper 28 quickly resetting, the impurities attached to the scraper 28 that cannot fall naturally are shaken off into the collection box 214, thereby improving the filtering effect of the filtering device.

[0053] When the movable shaft 22 rotates, it can drive the bevel gear 1 32 to rotate together. At the same time, the bevel gear 2 33 and the movable disk 34 are driven to rotate through the meshing of the bevel gear 1 32. Due to the rotation of the movable disk 34, the lifting block 36 can be driven to perform reciprocating lifting motion in the movable cavity 31 through the circular shaft 35. Due to the movement of the lifting block 36, the limit rod 37, the connecting frame 38 and the cone block 39 can be driven to perform reciprocating lifting motion together. Due to the reciprocating lifting of the cone block 39, the impurities remaining at the connecting pipe mouth of the filter box 21 and the material washing mechanism 1 can be reciprocated and squeezed through the conical surface of the cone block 39, and the impurities blocked at the connecting pipe mouth of the filter box 21 and the material washing mechanism 1 can be further tamped through by the reciprocating lifting of the support frame 315.

[0054] Under the repeated lifting action of the cone block 39, the connecting pipe 43, the bent pipe 42 and the piston 44 can be driven to reciprocate in the fixed cylinder 41. Due to the rise of the piston 44, the one-way valve 2 46 can be opened, and the filtered water in the filter box 21 can be pumped into the fixed cylinder 41. Due to the descent of the piston 44, the one-way valve 1 45 can be opened, so that the water in the fixed cylinder 41 passes through the piston 44 and enters the inside of the bent pipe 42. With the reciprocating lifting of the piston 44, the filtered water can be pumped into the cone block 39 through the bent pipe 42 and the connecting pipe 43, and the round block 310 can be pushed up. At this time, the straight spring 314 is stretched. With the repeated lifting of the cone block 39, water can be pumped into the cone block 39. When the connecting frame 38 rises, if the height of the liquid level inside the material washing mechanism 1 is higher than the floating ring 3 13. The float 313 can always drive the sealing ring 312 to seal the water outlet 311 under the action of buoyancy. If the height of the liquid level inside the material washing mechanism 1 drops below the float 313, it can be determined that the sewage inside the material washing mechanism 1 is about to be discharged. At this time, the motor stops running, and the cone block 39 keeps the connection open. Under the gravity of the float 313 and the sealing ring 312, the cone block 39 drops with the liquid level, and releases the sealing ring 312 from closing the water outlet 311. Under the elastic recovery action of the straight spring 314, the round block 310 can be driven to move downward, and the filtered water inside the cone block 39 is sprayed out through the water outlet 311, flushing the impurities remaining attached to the bottom of the inner cavity of the material washing mechanism 1, and flushing the impurities remaining attached to the bottom of the inner cavity of the material washing mechanism 1 into the interior of the filter box 21.
