Description

Technical Field

[0001] This invention relates to the field of water circulation treatment technology, specifically to a water circulation treatment device for a sand washing machine. Background Technology

[0002] In traditional sand washing operations, the problem of mud and sand sedimentation seriously restricts production efficiency and resource utilization. The sand washing wastewater contains a large number of suspended particles. After settling, fine mud and sand particles are rapidly deposited, causing siltation in circulation pipes and the bottom of water storage tanks, leading to pipe blockage. Existing water circulation systems mostly use simple sedimentation tanks for separation, which results in incomplete sedimentation of mud and sand and repeated increases in water turbidity, leading to a continuous deterioration in the quality of sand washing water and affecting the cleanliness of finished sand.

[0003] Patent CN212740969U discloses a water circulation treatment device for a sand washing machine. This patent includes multiple housings, with a feeding pipe and a water inlet pipe connected to the top of each housing. The other end of each water inlet pipe on the housing is connected to a main water inlet pipe. A rotating shaft is rotatably connected to the top wall of the housing. The rotating shaft is vertically arranged and fixedly connected to multiple sets of stirring blades within the housing. A partition plate is provided at the bottom of the rotating shaft. By setting multiple housings, coagulation, sedimentation, water intake, and drainage can be carried out separately in different housings. This not only greatly improves water treatment efficiency, ensuring it meets the normal water consumption requirements of the sand washing machine, but also avoids the situation where a single coagulation and sedimentation device can only perform one step at a time, leading to slow work efficiency. Although this patent solves the above problems, it still has the issue that when filtering a large amount of mud and sand at the same time, mud and sand can easily accumulate, affecting the efficiency of wastewater filtration and water circulation. Therefore, a water circulation treatment device for a sand washing machine is proposed to solve the aforementioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a water circulation treatment device for a sand washing machine, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a water circulation treatment device for a sand washing machine, including a sand filter barrel, an inlet pipe fixedly connected to the upper surface of the sand filter barrel, a main shaft rotatably connected to the inner surfaces of both ends of the sand filter barrel, an annular sleeve plate fixedly connected to the left side of the inner wall of the sand filter barrel, a rotating filter screen cylinder sleeved on the inner surface of the annular sleeve plate, limit rings fixedly connected to both sides of the circumferential surface of the main shaft, a friction unblocking device for unblocking the rotating filter screen cylinder provided inside the sand filter barrel, an impact filter slag device for accelerating the sedimentation of flocculants by impact provided inside the sand filter barrel, a sliding sleeve fixedly connected to the circumferential surface of the movable sleeve shaft, a support plate fixedly connected to the circumferential surface of the sliding sleeve, an agitator plate fixedly connected to the circumferential surface of the sliding sleeve, and a motor fixedly connected to the left end of the main shaft, and the motor is fixedly connected to the left side of the sand filter barrel. The inner surfaces of both ends of the rotating filter cylinder are in contact with the circumferential surface of the main shaft. The circumferential surface of the main shaft located between the two limiting rings has a reciprocating spiral groove, and the reciprocating spiral groove is movably connected to the inner surface of the movable sleeve shaft. The end of the support plate away from the sliding sleeve is fixedly connected to the inner surface of the rotating filter cylinder. The sliding sleeve and the circumferential surface of the limiting ring are sleeved together. Wastewater after sand washing is poured into the sand filter bucket through the water inlet pipe. The wastewater flows into the annular sleeve plate along the water inlet pipe, and then flows into the rotating filter cylinder from the annular sleeve plate. After passing through the rotating filter cylinder, the wastewater flows out from the mesh, while the sand and mud are blocked by the rotating filter cylinder. The motor is started, and the motor drives the main shaft to rotate, which in turn drives the movable sleeve shaft and the sliding sleeve to move back and forth through the spiral groove. The sliding sleeve then drives the rotating filter cylinder to move back and forth through the support plate. When the rotating filter cylinder moves back and forth, it generates inertia, causing the mud and sand deposited at the bottom of the rotating filter cylinder to shake.

[0006] Preferably, the friction unblocking device includes an arc-shaped fixed seat, a unblocking brush fixedly connected to the upper surface of the arc-shaped fixed seat, an inner slag discharge pipe fixedly connected to the lower surface of the filter sand bucket, and a solenoid valve fixedly connected to the inner surface of the inner slag discharge pipe. The friction unblocking device also includes a contact plate, an elastic telescopic rod fixedly connected to the right side of the contact plate, a limit plate fixedly connected to the lower surface of the inner wall of the filter sand bucket, a sliding rod fixedly connected to the left side of the contact plate, and a vibrating plate fixedly connected to the circumferential surface of the sliding rod. The arc-shaped fixed seat and the lower surface of the inner wall of the filter sand bucket are fixedly connected, the contact plate and the lower surface of the inner wall of the filter sand bucket are slidably connected, the elastic telescopic rod is fixedly connected to the right side of the inner wall of the filter sand bucket, the limit plate and the contact plate are in contact with each other on their front and rear sides, the limit plate and the vibrating plate are in contact with each other on their front and rear sides, the sliding rod and the inner surface of the arc-shaped fixed seat are in contact, and the vibrating plate and the lower surface of the inner wall of the filter sand bucket are slidably connected. The rotating filter cylinder is connected to the circumferential surface of the unclogging brush and the rotating filter cylinder. When the rotating filter cylinder moves back and forth, its lower surface contacts the unclogging brush on the arc-shaped fixed seat and generates friction, thereby scraping away the mud and sand stuck in the mesh of the rotating filter cylinder. After the filtered water is discharged from the filter sand bucket, the second solenoid valve is activated. At this time, some mud, sand and accumulated liquid flow out of the filter sand bucket through the external slag discharge pipe. When the rotating filter cylinder moves to the right, it pushes the contact plate to move to the right and squeezes the elastic telescopic rod. When the rotating filter cylinder moves to the left, the elastic telescopic rod drives the contact plate to slide to the left and reset between the limit plates, thereby causing the contact plate to move back and forth and vibrate due to the elasticity of the elastic telescopic rod. When the contact plate moves back and forth, it drives the slide rod to slide back and forth in the arc-shaped fixed seat. The slide rod then drives the oscillating plate to slide back and forth and collide with the arc-shaped fixed seat. After the arc-shaped fixed seat is impacted, the unclogging brush is affected and vibrates, thereby quickly shaking off the mud and sand stuck between the unclogging brushes.

[0007] Preferably, the impact filtration device includes an infusion pipe, the right end of which is fixedly connected to an outlet filter box. A partition is fixedly connected to the right side of the inner wall of the outlet filter box. An external slag discharge pipe is fixedly connected to the lower surface of the outlet filter box. A solenoid valve is fixedly connected to the inner surface of the external slag discharge pipe, and a connecting pipe is fixedly connected to the lower surface of the external slag discharge pipe. The impact filtration device also includes an impact screen plate. Side connecting plates are fixedly connected to the front and rear sides of the inner wall of the outlet filter box. An adsorption screen is fixedly connected to the lower surface of the partition. A push rod is fixedly connected to the right side of the contact plate. A support shaft is fixedly connected to the inner surface of the infusion pipe. The infusion pipe is fixedly connected to the right side of the filter sand tank. The impact screen plate is slidably connected to the inner surface of the outlet filter box. The upper surfaces of the impact screen plate and the partition are in contact with each other. A spring is provided between the right side of the impact screen plate and the left side of the side connecting plate. The upper surfaces of the side connecting plate and the partition are fixedly connected to the front and rear sides. The adsorption screen is fixedly connected to the inner surface of the outlet filter box. A spacer is provided between the right side of the adsorption screen and the outlet filter box for... The bentonite absorbs flocculants. The push rod and the inner surface of the support shaft are slidably connected. The right end of the push rod is in contact with the left side of the impact screen. Wastewater containing mud and sand flows from the filter sand tank into the infusion pipe. The water flow is compressed by the infusion pipe, generating a certain pressure and impact force, which then rushes into the effluent filter box. During the impact process, some water flows out of the effluent filter box through the impact screen, while the wastewater containing flocculants tumbles and falls to the bottom of the effluent filter box after hitting the impact screen. The flocculants falling to the bottom of the effluent filter box are subjected to the expansion force of the right side of the adsorption screen. After adsorption, the soil settles downwards. When most of the water has passed through the filter and flowed out of the effluent filter box, the second solenoid valve is opened, and the accumulated water and flocculated material flow into the external slag discharge pipe and then out through the connecting pipe. When the water flow impact decreases, the vibrating plate moves back and forth, driving the push rod to slide back and forth within the support shaft, and squeezing the impact screen plate to move to the right. After the push rod moves away from the impact screen plate, the spring drives the impact screen plate to reset, so that after the water flow force decreases, the impact screen plate continues to move back and forth and pushes the flocculated material adhering to the partition plate into the bottom of the effluent filter box.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This sand washing machine uses a water circulation treatment device. Wastewater flows out through the mesh of a rotating filter cylinder, while sand and mud are blocked by the rotating filter cylinder, thus quickly separating the sand and mud in the wastewater and improving the filtration efficiency. The stirring plate stirs the wastewater and flocculant, causing impurities in the wastewater to collect, further improving the filtration efficiency. The reciprocating movement of the rotating filter cylinder generates inertia, causing the mud and sand deposited at the bottom of the rotating filter cylinder to shake, preventing the mud and sand from accumulating and thus avoiding clogging of the rotating filter cylinder, thereby improving the filtration effect of the device.

[0010] 2. The sand washing machine uses a water circulation treatment device. When the rotating filter cylinder moves back and forth, its lower surface contacts and rubs against the unblocking brush on the arc-shaped fixed seat, thereby scraping away the mud and sand stuck in the mesh of the rotating filter cylinder. This prevents the mesh of the rotating filter cylinder from being blocked by mud and sand, which would lead to poor sewage filtration and further improve the filtration effect.

[0011] 3. The sand washing machine uses a water circulation treatment device. When the arc-shaped fixed seat is impacted, the unblocking brush is affected and vibrates, which quickly shakes off the mud and sand stuck between the unblocking brushes, preventing the unblocking brushes from being stuck with mud and sand. This allows for effective cleaning of the rotating filter cylinder surface for a long time, further improving the unblocking and cleaning effect.

[0012] 4. The sand washing machine uses a water circulation treatment device. During the impact process, some water flows out of the effluent filter box through the impact screen, while the wastewater containing flocculents tumbles and falls to the bottom of the effluent filter box after hitting the impact screen. The flocculents that fall to the bottom of the effluent filter box are adsorbed by the bentonite on the right side of the adsorption screen and then settle downwards, preventing the flocculents from floating upwards again.

[0013] 5. The sand washing machine uses a water circulation treatment device. The reciprocating movement of the vibrating plate drives the push rod to slide back and forth within the support shaft, and squeezes the impact screen to the right. After the push rod moves away from the impact screen, the spring drives the impact screen to reset, so that the water flow force is reduced. The impact screen continues to move back and forth and pushes the flocs adhering around the partition into the bottom of the outlet filter box, further improving the filtration quality.

[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 1-7One embodiment of the present invention is as follows: a water circulation treatment device for a sand washing machine, comprising a sand filter barrel 1, an inlet pipe 2 fixedly connected to the upper surface of the sand filter barrel 1, a main shaft 3 rotatably connected to the inner surfaces of both ends of the sand filter barrel 1, an annular sleeve plate 4 fixedly connected to the left side of the inner wall of the sand filter barrel 1, a rotating filter screen cylinder 5 sleeved on the inner surface of the annular sleeve plate 4, limit rings 6 fixedly connected to both sides of the circumferential surface of the main shaft 3, a friction unblocking device 8 for unblocking the rotating filter screen cylinder 5 provided inside the sand filter barrel 1, and an impact filter slag device 9 for accelerating the sedimentation of flocculants through impact. After the wastewater passes through the rotating filter screen cylinder 5, it flows out from the mesh, while the sand and mud are blocked by the rotating filter screen cylinder 5, thereby quickly separating the sand and mud in the wastewater and improving the filtration efficiency. The stirring plate 12 stirs the wastewater and flocculant to mix, causing impurities in the wastewater to collect, further improving the filtration efficiency. The filtration efficiency is achieved by fixing a sliding sleeve 10 to the circumferential surface of the movable sleeve shaft 7, a support plate 11 to the circumferential surface of the sliding sleeve 10, and an agitator 12 to the circumferential surface of the sliding sleeve 10. A motor is fixedly connected to the left end of the main shaft 3, and the motor is fixedly connected to the left side of the filter sand tank 1. The inner surfaces of both ends of the rotating filter screen 5 are in contact with the circumferential surface of the main shaft 3. A reciprocating spiral groove is opened on the circumferential surface of the main shaft 3 between the two limiting rings 6, and the reciprocating spiral groove is movably connected to the inner surface of the movable sleeve shaft 7. The end of the support plate 11 away from the sliding sleeve 10 is fixedly connected to the inner surface of the rotating filter screen 5. The sliding sleeve 10 and the circumferential surface of the limiting ring 6 are sleeved together. When the rotating filter screen 5 moves back and forth, it generates inertia, causing the mud and sand deposited at the bottom of the rotating filter screen 5 to shake, preventing the mud and sand from accumulating, thereby avoiding the clogging of the rotating filter screen 5 and improving the filtration effect of the device.

[0024] Working principle: Wastewater from sand washing is poured into the sand filter tank 1 through the inlet pipe 2. The wastewater flows into the annular sleeve plate 4 through the inlet pipe 2, and then into the rotating filter cylinder 5 from the annular sleeve plate 4. After passing through the rotating filter cylinder 5, the wastewater flows out through the mesh, while the sand and mud are blocked by the rotating filter cylinder 5, thus quickly separating the sand and mud in the wastewater and improving the filtration efficiency. The motor is started, and the motor drives the main shaft 3 to rotate, which in turn drives the moving sleeve shaft 7 and the sliding sleeve 10 to move back and forth through the spiral groove. The sliding sleeve 10 then drives the rotating filter cylinder 5 to move back and forth through the support plate 11. When the rotating filter cylinder 5 moves back and forth, it generates inertia, which makes the mud and sand deposited at the bottom of the rotating filter cylinder 5 shake, preventing the mud and sand from accumulating and thus avoiding the clogging of the rotating filter cylinder 5, thereby improving the filtration effect of the device.

[0025] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the friction unblocking device 8 includes an arc-shaped fixed seat 81, with an unblocking brush 82 fixedly connected to the upper surface of the arc-shaped fixed seat 81, an inner slag discharge pipe 83 fixedly connected to the lower surface of the filter sand barrel 1, and a solenoid valve 84 fixedly connected to the inner surface of the inner slag discharge pipe 83. When the rotating filter screen cylinder 5 moves back and forth, its lower surface contacts and rubs against the unblocking brush 82 on the arc-shaped fixed seat 81, thereby scraping away the mud and sand stuck in the mesh of the rotating filter screen cylinder 5, preventing the mesh of the rotating filter screen cylinder 5 from being blocked by mud and sand, thus preventing the sewage filtration from being obstructed and further improving the filtration effect. The friction unblocking device 8 also includes a contact plate 85, with an elastic telescopic rod 86 fixedly connected to the right side of the contact plate 85, a limit plate 87 fixedly connected to the lower surface of the inner wall of the filter sand barrel 1, and a sliding rod 88 fixedly connected to the left side of the contact plate 85. A vibrating plate 89 is fixedly connected to the circumferential surface of the sliding rod 88. An arc-shaped fixed seat 81 is fixedly connected to the lower surface of the inner wall of the filter sand bucket 1. A contact plate 85 is slidably connected to the lower surface of the inner wall of the filter sand bucket 1. An elastic telescopic rod 86 is fixedly connected to the right side of the inner wall of the filter sand bucket 1. A limiting plate 87 and the front and rear sides of the contact plate 85 are in contact with each other. A limiting plate 87 and the front and rear sides of the vibrating plate 89 are in contact with each other. The sliding rod 88 and the inner surface of the arc-shaped fixed seat 81 are in contact with each other. The vibrating plate 89 and the lower surface of the inner wall of the filter sand bucket 1 are slidably connected. The unblocking brush 82 and the circumferential surface of the rotating filter screen 5 are in contact with each other. When the arc-shaped fixed seat 81 is impacted, the unblocking brush 82 is affected and vibrates, which quickly shakes off the mud and sand stuck between the unblocking brushes 82, preventing the unblocking brushes 82 from being stuck by mud and sand. This allows for effective cleaning of the surface of the rotating filter screen 5 for a long time, further improving the unblocking and cleaning effect.

[0026] Working principle: When the rotating filter cylinder 5 moves back and forth, its lower surface contacts and rubs against the unblocking brush 82 on the arc-shaped fixed seat 81, thereby scraping away the mud and sand stuck in the mesh of the rotating filter cylinder 5. This prevents the mesh of the rotating filter cylinder 5 from being blocked by mud and sand, which would lead to poor sewage filtration and further improve the filtration effect. After the filtered water is discharged from the filter sand tank 1, the solenoid valve 2 95 is activated. At this time, some mud, sand and accumulated liquid flow out of the filter sand tank 1 through the external slag discharge pipe 94. When the rotating filter cylinder 5 moves to the right, it pushes the contact plate 85 to move to the right and squeezes the elastic telescopic rod 86. When the rotating filter cylinder 5 moves to the left, the elastic telescopic rod 86 drives the contact plate. The contact plate 85 slides to the left between the limiting plates 87 to reset, thereby causing the contact plate 85 to move back and forth. It is also affected by the elasticity of the elastic telescopic rod 86 to vibrate. When the contact plate 85 moves back and forth, it drives the slide rod 88 to slide back and forth in the arc-shaped fixed seat 81. The slide rod 88 then drives the oscillating plate 89 to slide back and forth and collide with the arc-shaped fixed seat 81. After the arc-shaped fixed seat 81 is impacted, the unblocking brush 82 is affected and vibrates, thereby quickly shaking off the mud and sand stuck between the unblocking brushes 82, preventing the unblocking brushes 82 from being stuck with mud and sand, and thus enabling effective cleaning of the surface of the rotating filter cylinder 5 for a long time, further improving the unblocking and cleaning effect.

[0027] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the impact filter device 9 includes a liquid inlet pipe 91, with an outlet filter box 92 fixedly connected to the right end of the liquid inlet pipe 91. A partition plate 93 is fixedly connected to the right side of the inner wall of the outlet filter box 92. An external discharge pipe 94 is fixedly connected to the lower surface of the outlet filter box 92. A solenoid valve 95 is fixedly connected to the inner surface of the external discharge pipe 94. A connecting pipe 96 is fixedly connected to the lower surface of the external discharge pipe 94. During the impact process, part of the water flows out of the outlet filter box 92 through the impact mesh plate 97. The wastewater containing flocculent material impacts the impact screen 97 and tumbles into the bottom of the effluent filter box 92. The flocculent material at the bottom of the effluent filter box 92 is adsorbed by the bentonite on the right side of the adsorption screen 99 and settles downwards, preventing the flocculent material from floating upwards again. The impact filter device 9 also includes an impact screen 97. Side connecting plates 98 are fixedly connected to the front and rear sides of the inner wall of the effluent filter box 92. An adsorption screen 99 is fixedly connected to the lower surface of the partition 93. A push rod 910 is fixedly connected to the right side of the contact plate 85. The inner surface of the infusion pipe 91 is fixedly connected to... A support shaft 911 is provided. The infusion pipe 91 is fixedly connected to the right side of the filter sand tank 1. The impact screen plate 97 is slidably connected to the inner surface of the effluent filter box 92. The upper surfaces of the impact screen plate 97 and the partition plate 93 are in contact with each other. A spring is provided between the right side of the impact screen plate 97 and the left side of the side connecting plate 98. The upper surfaces of the side connecting plate 98 and the partition plate 93 are fixedly connected on both the front and rear sides. The adsorption screen 99 is fixedly connected to the inner surface of the effluent filter box 92. Bentonite for adsorbing flocculants is provided between the right side of the adsorption screen 99 and the effluent filter box 92. A push rod 910 is also provided. The push rod 910 is slidably connected to the inner surface of the support shaft 911. The right end of the push rod 910 is in contact with the left side of the impact screen 97. The oscillating plate 89 moves back and forth, causing the push rod 910 to slide back and forth inside the support shaft 911 and squeeze the impact screen 97 to move to the right. After the push rod 910 moves away from the impact screen 97, the spring drives the impact screen 97 to reset. After the water flow force is reduced, the impact screen 97 continues to move back and forth and pushes the flocculent material adhering to the partition plate 93 into the bottom of the outlet filter box 92, further improving the filtration quality.

[0028] Working principle: Wastewater separated from mud and sand flows from the filter sand tank 1 into the infusion pipe 91. The water flow is compressed by the infusion pipe 91, generating a certain pressure and impact force, which then rushes into the effluent filter box 92. During the impact process, some water flows out of the effluent filter box 92 through the impact screen 97, while the wastewater containing flocculents crashes into the impact screen 97 and falls to the bottom of the effluent filter box 92. The flocculents at the bottom of the effluent filter box 92 are adsorbed by the bentonite on the right side of the adsorption screen 99 and settle downwards, preventing the flocculents from floating upwards again. When most of the water has passed through the filter and flows out of the effluent filter box... After the filter box 92 is opened, the solenoid valve 2 95 is opened, and the accumulated water and flocculated material flow into the external sludge discharge pipe 94, and then out through the connecting pipe 96. When the water flow impact decreases, the vibrating plate 89 moves back and forth, driving the push rod 910 to slide back and forth in the support shaft 911, and squeezing the impact screen plate 97 to move to the right. After the push rod 910 moves away from the impact screen plate 97, the spring drives the impact screen plate 97 to reset, so that after the water flow impact force decreases, the impact screen plate 97 continues to move back and forth and pushes the flocculated material adhering to the partition plate 93 into the bottom of the outlet filter box 92, further improving the filtration quality.
