Description

Technical Field

[0001] This utility model relates to the field of waste acid and acid water recycling technology, specifically a filtration device for waste acid and acid water recycling with a cleaning mechanism. Background Technology

[0002] In industrial production processes, many technologies generate waste acid wastewater, such as metal processing, electroplating, and chemical industries. This waste acid wastewater typically contains various impurities, such as metal ions, solid particles, and organic matter. Direct discharge not only causes serious environmental pollution but also wastes a significant amount of resources. Therefore, the recycling and treatment of waste acid wastewater is crucial; filtration is a key step in this process. Through filtration, solid particles and impurities in the waste acid wastewater can be removed, improving its purity and providing favorable conditions for further processing.

[0003] Currently, Chinese utility model patent application CN210001709U discloses a wastewater and waste acid recovery filtration device, including a shell and a stirring motor. The inner cavity of the shell contains a stirring chamber and a storage chamber. The stirring chamber is connected above the storage chamber. The top of the stirring chamber has an inlet, and a fixed bearing is fixedly connected to the outer wall of the top center of the stirring chamber. The stirring motor is connected to the outer wall of the top center of the stirring chamber. The output shaft of the stirring motor is fixedly connected to a main shaft. The outer wall of the main shaft is fixedly connected to the inner ring of the fixed bearing, and the end of the main shaft extends into the stirring chamber and is fixedly connected to a stirring rod. A mixing chamber is connected to the outer wall of the top of the shell, with an inlet at the top. A rotating shaft is movably connected to the inner wall of the mixing chamber. This wastewater and waste acid recovery filtration device does not generate new pollutants, has excellent filtration effect, is not easily clogged, and offers advantages such as convenient use, time saving, and high efficiency.

[0004] The aforementioned filtration devices primarily enhance the filtration effect of wastewater and waste acid by moving the filter screen left and right. However, this design has shortcomings in practical applications. The left-right movement of the filter screen cannot remove impurities, which remain on the screen, affecting the filtration effect. Frequent left-right movement of the filter screen intensifies the mechanical friction between the screen and the device frame, leading to faster screen wear, shorter replacement cycles, and increased maintenance costs. Furthermore, screen damage can severely reduce filtration accuracy, making it difficult to meet the high standards required for industrial wastewater treatment. Utility Model Content

[0005] One technical problem to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a waste acid water recycling filter device with a cleaning mechanism, which solves the problems of poor filtration effect and difficulty in handling impurity accumulation in existing devices.

[0007] Two technical solutions

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A waste acid water recycling filtration device with a cleaning mechanism includes a filter chamber, and further includes a filter structure, a stirring mechanism, a cleaning structure, and a limiting component. The bottom of the filter chamber is fixedly connected to a discharge channel. The filter structure includes a rotating shaft rotatably connected to the discharge channel and a filter screen fixedly connected to the rotating shaft. The limiting component includes a limiting sleeve fixedly connected to the discharge channel, a sliding sleeve slidably fitted onto the rotating shaft, and a limiting block fixedly connected to the sliding sleeve. The limiting sleeve has a receiving hole, and symmetrical limiting openings are formed on the inner walls of both sides of the receiving hole. The limiting block is engaged within the limiting openings. A sliding strip is fixedly connected to the inner wall of the sliding sleeve cavity, and a sliding opening is formed on the rotating shaft. The sliding strip slides against the inner wall of the sliding opening. This device is used to clean impurities accumulated on the filter screen and improve the filtration efficiency of the filter screen.

[0010] Preferably, the sliding grooves are arranged in a ring array around the rotating shaft. This ensures that the slide bar is subjected to uniform force in all directions, making the sliding sleeve slide more smoothly on the rotating shaft.

[0011] Preferably, a spring is provided inside the sliding sleeve cavity, with one end of the spring fixedly connected to the rotating shaft and the other end fixedly connected to the inner wall of the sliding sleeve cavity. This reduces the probability of operational errors or omissions that may occur when manually pushing the sliding sleeve back to its original position.

[0012] Preferably, the stirring mechanism includes a motor fixedly connected to the top wall of the filter chamber, a spiral stirring blade fixedly connected to the output end of the motor, and a stirring seat fixedly connected to the inner wall of the filter chamber. The stirring seat slides against the outer wall of the spiral stirring blade, and a stirring rod is fixedly connected to the bottom of the output end of the motor. The stirring seat provides support for the spiral stirring blade to ensure smooth rotation. The spiral stirring blade and the stirring rod are used to guide the acid water to form a complex flow field, thereby enhancing the stirring and mixing effect.

[0013] Preferably, the stirring rod has a through hole. This allows the acid water to form turbulence at the through hole, breaking its original regular flow and causing the acid water to move irregularly in all directions, thereby further improving the mixing effect.

[0014] Preferably, the cleaning structure includes a water pump fixedly connected to the filter chamber, and a nozzle fixedly connected to the top wall of the filter chamber's inner cavity. The water pump is connected to the nozzle via a delivery pipe, which is fixedly connected to the filter chamber. This is used to flush impurities from the filter screen and the inner wall of the filter chamber to the outside of the filter chamber.

[0015] Three beneficial effects

[0016] This invention provides a filtration device for recycling waste acid water with a cleaning mechanism. It has the following beneficial effects:

[0017] 1. When cleaning the filter screen, the operator manually slides the sliding sleeve to disengage the limiting block from the limiting port, thus releasing the lock on the rotating shaft. Rotating the sliding sleeve causes the rotating shaft to flip, allowing some impurities to fall off due to gravity. Then, the sliding sleeve is pushed back in, causing the limiting block to engage with the limiting port and lock the rotating shaft. Next, the cleaning mechanism is activated, and cleaning fluid is delivered to the filter chamber. The cleaning fluid flushes the filter screen, washing away a large amount of residual impurities, improving cleaning efficiency, solving the problem of impurity accumulation, and enhancing the filter screen's filtration performance, enabling the filtration device to operate more efficiently and for a longer period.

[0018] 2. The motor drives the spiral stirring blades to rotate, causing the acid water to flow spirally within the filter chamber for thorough mixing. This reduces concentration stratification and sedimentation, improving filtration efficiency. Simultaneously, it pushes the acid water to flow evenly onto the filter screen, balancing pressure and extending the filter screen's lifespan. The stirring rod at the bottom of the motor output rotates to reduce acid water sedimentation at the bottom of the chamber. The funnel-shaped stirring seat fits against the outer wall of the spiral stirring blades, providing support for smooth rotation and guiding the acid water to form a complex flow field, enhancing the mixing effect and improving the uniformity and efficiency of acid water treatment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A filtration device for recycling waste acid water with a cleaning mechanism includes a filter chamber 10, and further includes a filter structure 20, a stirring mechanism 30, a cleaning structure 40, and a limiting component 50. The bottom of the filter chamber 10 is fixedly connected to a discharge channel 11. The filter structure 20 includes a rotating shaft 21 rotatably connected to the discharge channel 11 and a filter screen 22 fixedly connected to the rotating shaft 21. The limiting component 50 includes a limiting sleeve 51 fixedly connected to the discharge channel 11, a sliding sleeve 52 slidably sleeved on the rotating shaft 21, and a limiting block 53 fixedly connected to the sliding sleeve 52. The limiting sleeve 51 has a receiving hole 511, and symmetrically opened limiting openings 512 are opened on the inner walls of both sides of the receiving hole 511. The limiting block 53 is engaged in the limiting opening 512. A sliding strip 521 is fixedly connected to the inner wall of the inner cavity of the sliding sleeve 52. A sliding opening 211 is opened on the rotating shaft 21, and the sliding strip 521 slides against the inner wall of the sliding opening 211.

[0027] When cleaning the filter screen 22, the operator manually slides the sliding sleeve 52 away from the rotating shaft 21, causing the limiting block 53 to disengage from the limiting port 512 and releasing the lock on the rotating shaft 21. Since the sliding strip 521 and the sliding port 211 are slidably connected, rotating the sliding sleeve 52 will cause the rotating shaft 21 to rotate 180 degrees, allowing some impurities on the filter screen 22 to fall off due to gravity. Then, the sliding sleeve 52 is pushed again, causing the limiting block 53 to engage with the limiting port 512 and lock the rotating shaft 21. Subsequently, the cleaning structure 40 is activated, and the cleaning liquid is quickly transported to the filter chamber 10. The cleaning liquid washes the filter screen 22, washing away a large amount of residual impurities, improving the cleaning efficiency, solving the problem of impurity accumulation and difficulty in handling, allowing impurities to be smoothly removed from the filter screen 22, improving the filtration performance of the filter screen 22, and enabling the waste acid water recycling filter device to operate more efficiently for a longer period of time.

[0028] The cleaning structure 40 includes a water pump 41 fixedly connected to the filter chamber 10 and a nozzle 43 fixedly connected to the top wall of the inner cavity of the filter chamber 10. The water pump 41 is connected to the nozzle 43 through a delivery pipe 42, which is fixedly connected to the filter chamber 10. In the cleaning structure 40, the water pump 41 serves as the power core, providing power to the cleaning liquid so that it flows to the nozzle 43 in the delivery pipe 42. The nozzle 43 sprays the cleaning liquid evenly to form a cleaning network. With the cooperation of all parts, the impurities on the filter screen 22 and the inner wall of the filter chamber 10 are washed away, allowing the filtration device to operate stably and enabling the filter screen 22 to have a better filtration effect, providing reliable support for the recycling of waste acid water.

[0029] The stirring mechanism 30 includes a motor 31 fixedly connected to the top wall of the filter chamber 10, a spiral stirring blade 33 fixedly connected to the output end of the motor 31, a stirring seat 32 fixedly connected to the inner wall of the filter chamber 10, the stirring seat 32 slidingly fitting against the outer wall of the spiral stirring blade 33, and a stirring rod 34 fixedly connected to the bottom of the output end of the motor 31.

[0030] The motor 31 is started, which drives the spiral stirring blade 33 to rotate, allowing the acid water to flow spirally within the filter chamber 10, achieving thorough mixing. This reduces concentration stratification and sedimentation, improving filtration efficiency. Simultaneously, it pushes the acid water to flow evenly towards the filter screen 22, balancing pressure and extending the service life of the filter screen 22. The stirring rod 34 at the bottom of the output end of the motor 31 rotates, reducing the probability of static sedimentation of the acid water at the bottom of the filter chamber 10. The funnel-shaped stirring seat 32 fits against the outer wall of the spiral stirring blade 33, providing support for smooth rotation and guiding the acid water to form a complex flow field, enhancing the mixing effect and improving the uniformity and efficiency of acid water treatment.

[0031] The stirring rod 34 has a through hole 35. When the stirring rod 34 rotates with the motor 31, the acid water forms turbulence at the through hole 35, breaking its original regular flow and causing the acid water to move irregularly in all directions, further enhancing the mixing. At the same time, the through hole 35 allows the acid water to not only flow around the stirring rod 34 during stirring, but also pass through the hole, expanding the range of disturbance of the acid water by the stirring rod 34, and driving more areas of acid water in the filter chamber 10 to participate in the mixing, thus enhancing the overall mixing effect.

[0032] The sliding openings 211 are arranged in a ring array around the rotating shaft 21. When the sliding sleeve 52 slides along the rotating shaft 21, the four sliding openings 211 arranged in a ring array play a key role. On the one hand, they ensure that the slider 521 is evenly stressed in all directions, avoiding jamming or displacement due to uneven stress. On the other hand, the four sliding openings 211 create four stable sliding paths for the slider 521, improving the smoothness and stability of the sliding sleeve 52. At the same time, this design increases the contact area between the sliding sleeve 52 and the rotating shaft 21, making the sliding of the sliding sleeve 52 on the rotating shaft 21 smoother.

[0033] A spring 54 is installed inside the inner cavity of the sliding sleeve 52. One end of the spring 54 is fixedly connected to the rotating shaft 21, and the other end is fixedly connected to the inner wall of the inner cavity of the sliding sleeve 52. When flipping the filter screen 22, the operator pulls the sliding sleeve 52 to slide it away from the rotating shaft 21, so that the limiting block 53 disengages from the limiting port 512 to release the lock on the rotating shaft 21. At this time, the spring 54 will be stretched and generate a reaction force. When the sliding sleeve 52 is rotated, the rotating shaft 21 and the filter screen 22 will be rotated 180 degrees. After the rotation is completed, the operator no longer applies external force to the sliding sleeve 52. At this time, the spring 54 will automatically push the sliding sleeve 52 back to the initial position under the elastic action, so that the limiting block 53 will be locked into the limiting port 512 again, thereby restricting the rotation of the rotating shaft 21. This automatic reset function simplifies the operation process, improves the convenience and efficiency of the device, and reduces the probability of operation errors or omissions that may occur when manually pushing the sliding sleeve 52 back to its original position.

[0034] The working principle of this device is as follows: Acidic water is transported to the filter chamber 10, the motor 31 starts, driving the spiral stirring blade 33 to rotate, so that the acidic water flows spirally to fully mix, reduce concentration stratification and sedimentation, and improve filtration efficiency. The bottom stirring rod 34 at the output end of the motor 31 rotates, reducing the probability of static sedimentation of the acidic water at the bottom of the chamber. The acidic water forms turbulence at the through hole 35, and the irregular movement in all directions further enhances mixing. The funnel-shaped stirring seat 32 fits against the outer wall of the spiral stirring blade 33, supporting its stable rotation and guiding the acidic water to form a complex flow field, enhancing the stirring effect. The stirred acidic water flows to the discharge channel 11, and flows out after being filtered by the filter screen 22.

[0035] Filter screen 22 accumulates impurities after long-term use and requires cleaning. The operator manually slides the sliding sleeve 52 away from the rotating shaft 21, causing the limiting block 53 to disengage from the limiting port 512 and unlocking the rotating shaft 21, stretching the spring 54. Because the sliding strip 521 is slidably connected to the sliding port 211, rotating the sliding sleeve 52 causes the rotating shaft 21 to rotate 180 degrees, causing some impurities to fall off due to gravity. Releasing the sliding sleeve 52 allows the spring 54 to push it back under elasticity, and the limiting block 53 re-engages into the limiting port 512, locking the rotating shaft 21. Then, the water pump 41 is started, and the cleaning solution is sprayed from the nozzle 43 through the delivery pipe 42. As it passes through the spiral stirring blades 33, the funnel-shaped structure of the stirring seat 32 increases the flow rate of the cleaning solution, flushing the filter screen 22, washing away residual impurities, improving cleaning efficiency, solving the problem of impurity accumulation, improving the filtration performance of the filter screen 22, and ensuring the long-term efficient operation of the device.
