Description

Technical Field

[0001] This invention relates to the field of filter cleaning technology, specifically to a security filter cartridge recycling and cleaning device with sterilization function. Background Technology

[0002] Security filters are suitable for separating solid suspended particles in liquids, especially toxic media. They are widely used in water treatment, metallurgy, petroleum, chemical, power, light industry, food, pharmaceutical, textile, and paper industries, particularly in power and steel industries where production water needs to be recycled. Most common security filters use stainless steel for the outer shell and contain filter elements. They are mainly used after multi-media pretreatment filtration and before membrane filtration equipment such as reverse osmosis and ultrafiltration to remove fine substances, such as tiny quartz sand and activated carbon particles, from multi-media filtration, ensuring water filtration accuracy and protecting the membrane filter elements from damage by large particles.

[0003] Security filters primarily rely on filter cartridges for filtration. However, as filtration time increases, the number of suspended particles trapped on the surface of the filter cartridge gradually increases, leading to blockage. Simultaneously, bacteria can easily grow on the filter cartridge surface, causing filter cartridge failure. Therefore, regular cleaning of the filter cartridge is necessary to maintain its filtration efficiency. Existing continuous filter cartridge cleaning devices, if using a drop-type discharge method, will discharge the filter cartridge along with the cleaning solution. Conversely, an upward-lift discharge method is more complex, resulting in low cleaning efficiency. Therefore, this paper proposes a security filter cartridge recycling and cleaning device with sterilization function. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a security filter cartridge recycling and cleaning device with sterilization function.

[0005] The technical solution of the present invention is: a security filter cartridge recycling and cleaning device with sterilization function, comprising a cleaning tank and a feeding pipe disposed on the top surface of the cleaning tank;

[0006] The cleaning tank includes a drive shaft vertically arranged inside the cleaning tank, a drive sleeve rotatably sleeved on the drive shaft, a rotating disk horizontally arranged inside the cleaning tank, a first drive mechanism arranged on the cleaning tank for driving the drive shaft to rotate, and a second drive mechanism arranged on the cleaning tank for driving the drive sleeve to rotate; a fixing seat for fixing the filter element is provided on the bottom surface of the cleaning tank at the corresponding position of the feeding pipe.

[0007] The upper end of the drive shaft passes through the top surface of the cleaning tank and is connected to the first drive mechanism. The lower end of the drive shaft is fixedly connected to the rotating disk. The rotating disk is provided with a plurality of cleaning sleeves that are switched to connect with the feed pipe by rotating the disk.

[0008] Multiple cleaning sleeves are rotatably connected to a rotating disk, and a first gear is rotatably mounted on the rotating disk. Each cleaning sleeve is equipped with a toothed ring for meshing with the first gear.

[0009] The lower end of the transmission sleeve passes through the top surface of the cleaning tank and is fixedly connected to the first gear. An air-inflating mechanism is provided on the transmission shaft. The inner wall of the cleaning sleeve is provided with bristles for cleaning the filter element, and a clamping mechanism is provided to clamp the filter element by inflating it with the air-inflating mechanism. The cleaning tank is provided with a lifting mechanism for clamping and cooperating with the clamping mechanism to drive the filter element to move up and down.

[0010] The cleaning tank has multiple ultraviolet lamps on its side wall for sterilizing the filter element. The cleaning tank is equipped with a liquid addition pipe, and the bottom of the cleaning tank has a discharge port that corresponds to one of the cleaning sleeves by rotating a rotating disk. The discharge port is equipped with a feeding mechanism for continuously releasing the filter element and recovering the cleaning liquid.

[0011] Explanation: The above device adds filter elements into the cleaning sleeve through the feeding pipe. The second drive mechanism drives the first gear to rotate, causing the cleaning sleeve to rotate. The lifting mechanism drives the rotating disk to rise and fall, so that the cleaning sleeve moves up and down while rotating to clean the filter element. Then, the air inflation mechanism inflates the clamping mechanism, causing the clamping mechanism to clamp the filter element. The lifting mechanism continues to lift the filter element. The first drive mechanism drives the transmission shaft to rotate, causing the rotating disk to rotate to the discharge port. The filter element and part of the cleaning liquid are discharged through the feeding mechanism, so that the device can continuously clean the filter element.

[0012] Furthermore, the first drive mechanism includes a lifting plate rotatably sleeved on the upper end of the transmission shaft, a first motor mounted on the lifting plate, a fifth gear fixedly sleeved on the output shaft of the first motor, and a sixth gear fixedly sleeved on the upper end of the transmission shaft and meshing with the fifth gear; the lifting plate is connected to the cleaning tank.

[0013] Explanation: The first motor drives the fifth gear to rotate, and the fifth gear drives the transmission shaft to rotate through the sixth gear.

[0014] Furthermore, the second drive mechanism includes a second gear sleeved on the transmission sleeve via a spline, and a second motor disposed on the top surface of the cleaning tank;

[0015] The second gear is rotatably connected to the connecting cylinder on the top surface of the cleaning tank, and the second gear is provided with an annular groove for engaging with the connecting cylinder. The output shaft of the second motor is provided with a fourth gear for meshing with the second gear.

[0016] Explanation: The second motor can drive the fourth gear to rotate, which in turn drives the second gear to rotate, and the second gear will drive the transmission sleeve to rotate.

[0017] Furthermore, the lifting mechanism includes two lead screws disposed on the top surface of the cleaning tank and located on both sides of the drive shaft, and a connecting plate disposed above the lifting plate;

[0018] The upper end of the lead screw passes through the lifting plate and is rotatably connected to the connecting plate, the lower end of the lead screw is rotatably connected to the top surface of the cleaning tank, and the lifting plate is threadedly connected to the lead screw. A third gear for meshing with the second gear is sleeved on the lead screw; the upper end of the transmission sleeve is in contact with the lifting plate.

[0019] The connecting cylinder is movably connected to the cleaning tank, and a connecting ring is fixedly sleeved on the connecting cylinder. The top surface of the cleaning tank is provided with multiple electric push rods for driving the connecting ring to move up and down to control the spline engagement or disengagement of the second gear and the transmission sleeve.

[0020] Explanation: When the second motor drives the second gear to rotate, the second gear can drive the lead screw to rotate through the third gear. At the same time, the rotation of the transmission sleeve can be controlled by extending or retracting the electric push rod to engage or disengage the spline of the second gear with the transmission sleeve.

[0021] Furthermore, the drive shaft is provided with a vertical gas channel, and the bottom surface of the rotating disk is fixedly provided with a main gas chamber that communicates with the gas channel. Each cleaning sleeve is rotatably sealed with a gas distribution chamber for supplying gas to the corresponding clamping mechanism. Multiple gas distribution chambers are fixedly connected to the bottom surface of the rotating disk, and the main gas chamber is connected to the gas distribution chambers one by one through multiple pipes.

[0022] The inflation mechanism is an airbag fixedly installed on the upper end of the transmission shaft and in contact with the connecting plate. The air outlet of the airbag is connected to the gas channel, and a one-way valve is provided in the air inlet of the airbag.

[0023] The rotating disk is provided with a first exhaust port that is connected to the main air chamber, and the first gear is provided with a second exhaust port for connecting the first exhaust port to exhaust air by rotating the rotating disk, and a one-way valve is provided in the first exhaust port.

[0024] Note: When the lifting mechanism drives the drive shaft to rise, the connecting plate will squeeze the airbag, causing the gas inside the airbag to fill the clamping mechanism.

[0025] Furthermore, the clamping mechanism includes multiple sliding holes disposed on the inner wall of the cleaning sleeve and communicating with the corresponding air distribution chambers, and a sliding rod disposed in the sliding holes with a sliding seal.

[0026] Note: After the air pressure in the air distribution chamber increases, the slide bar can extend under the action of air pressure, so that multiple air pressure bars can clamp the filter element, and the clamping is stable and practical.

[0027] Furthermore, the side wall of the rotating disk is provided with a plurality of cleaning blocks for cleaning the ultraviolet lamps. The cleaning blocks correspond one-to-one with the positions of the ultraviolet lamps and are vertically slidably connected to the inner wall of the cleaning tank.

[0028] Note: When the rotating disc moves up and down, it can also cause the cleaning block to slide up and down, so that the cleaning block can clean the surface of the UV lamp and prevent dirt from adhering to the UV lamp, which would affect the sterilization effect.

[0029] Furthermore, the feeding mechanism includes a feeding pipe vertically arranged on the bottom surface of the cleaning tank and communicating with the discharge port, a rotating cylinder vertically arranged and rotatably connected to the bottom surface of the cleaning tank, and two feeding discs horizontally arranged below the cleaning tank, both of which are fixedly sleeved on the rotating cylinder.

[0030] The feeding pipe consists of a thick pipe and two thin pipes respectively located at the upper and lower ends of the thick pipe. The two feeding discs are located at the upper and lower ends of the thick pipe, and one side of the feeding disc extends into the thick pipe to close the upper and lower ends of the thick pipe. The feeding disc is provided with an opening for connecting with the thin pipe by rotating it, and the openings of the two feeding discs are staggered.

[0031] The rotating drum is vertically equipped with a sliding rod for sliding up and down in coordination with the rotating disk. The upper end of the sliding rod passes through the bottom surface of the cleaning tank and is fitted with a limiting ring. The lower end of the sliding rod is threadedly connected to one of the feeding discs. The sliding rod is slidably and sealingly connected to the cleaning tank, and the limiting ring is connected to the bottom surface of the cleaning tank by a spring.

[0032] Instructions: When the rotating disc descends, it will press down on the sliding rod. The sliding rod will slide down and engage with the threaded part to drive the two feeding discs to rotate. This will cause the openings of the two feeding discs to connect with the fine tube one after another, allowing the filter element to be discharged from the feeding tube and controlling the amount of cleaning liquid discharged each time to avoid excessive consumption of cleaning liquid.

[0033] Furthermore, a reflux pump is provided below the cleaning tank. The input end of the reflux pump is connected to the side wall of the thick pipe, and the output end of the reflux pump is connected to the cleaning tank through an infusion pipe. A monitoring instrument for monitoring the concentration of the cleaning solution is provided on the infusion pipe.

[0034] Note: The return pump can transfer the cleaning fluid in the coarse pipe back to the cleaning tank, further reducing the loss of cleaning fluid.

[0035] The beneficial effects of this invention are:

[0036] (1) The present invention adds a filter element into the cleaning sleeve through the feeding pipe. The first gear can be driven to rotate through the second drive mechanism. With the cooperation of the lifting mechanism, the cleaning sleeve rotates and moves up and down to clean the filter element. Then, the clamping mechanism is inflated through the air inflation mechanism to clamp the filter element. The filter element is lifted by the lifting mechanism. The rotating disk is driven to rotate to the discharge port through the first drive mechanism. The filter element and part of the cleaning liquid are discharged through the feeding mechanism, so that the device can continuously clean the filter element.

[0037] (2) When the rotating disk moves up and down, the rotating disk can drive the cleaning block to slide up and down, so that the cleaning block can clean the surface of the ultraviolet lamp and avoid stains adhering to the ultraviolet lamp, which would affect the sterilization effect.

[0038] (3) When the rotating disk descends, the rotating disk will press down the sliding rod. The sliding rod slides down and will engage with the thread to drive the two feeding disks to rotate, so that the openings of the two feeding disks connect with the thin tube one after the other, so that the filter element is discharged from the feeding pipe and the amount of cleaning liquid discharged each time is controlled to avoid excessive consumption of cleaning liquid.

Detailed Implementation

[0050] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0051] Example 1

[0052] like Figure 1 As shown, a security filter cartridge recycling and cleaning device with sterilization function includes a cleaning tank 1 and a feeding pipe 2 disposed on the top surface of the cleaning tank 1.

[0053] The cleaning tank 1 includes a drive shaft 3 vertically arranged inside the cleaning tank 1, a drive sleeve 34 rotatably sleeved on the drive shaft 3, a rotating disk 31 horizontally arranged inside the cleaning tank 1, a first drive mechanism arranged on the cleaning tank 1 for driving the drive shaft 3 to rotate, and a second drive mechanism arranged on the cleaning tank 1 for driving the drive sleeve 34 to rotate; a fixing seat 19 for fixing the filter element is provided on the bottom surface of the cleaning tank 1 at the corresponding position of the feeding pipe 2; three air pressure rods are provided on the inner wall of the fixing seat 19, and an air pump for charging and discharging air to the air pressure rods is provided on the bottom surface of the cleaning tank 1 (not shown in the figure), and the air pump adopts a prior art product;

[0054] like Figure 2 As shown, the upper end of the drive shaft 3 passes through the top surface of the cleaning tank 1 and is connected to the first drive mechanism. The lower end of the drive shaft 3 is fixedly connected to the rotating disk 31. The rotating disk 31 is provided with eight cleaning sleeves 32 that are switched to connect with the feed pipe 2 by rotating them.

[0055] All eight cleaning sleeves 32 are rotatably connected to the rotating disk 31. The rotating disk 31 is rotatably equipped with a first gear 33, and each cleaning sleeve 32 is equipped with a toothed ring for meshing with the first gear 33.

[0056] The lower end of the transmission sleeve 34 passes through the top surface of the cleaning tank 1 and is fixedly connected to the first gear 33. An air inflation mechanism is provided on the transmission shaft 3. The inner wall of the cleaning sleeve 32 is provided with bristles for cleaning the filter element and a clamping mechanism for clamping the filter element by air inflation. The cleaning tank 1 is provided with a lifting mechanism for clamping and cooperating with the clamping mechanism to drive the filter element to move up and down.

[0057] The first drive mechanism includes a lifting plate 113 rotatably sleeved on the upper end of the transmission shaft 3, a first motor 35 mounted on the lifting plate 113, a fifth gear 351 fixedly sleeved on the output shaft of the first motor 35, and a sixth gear 36 fixedly sleeved on the upper end of the transmission shaft 3 and meshing with the fifth gear 351; the lifting plate 113 is connected to the cleaning tank 1, and the first motor 35 adopts a product of existing technology.

[0058] like Figure 3 As shown, the second drive mechanism includes a second gear 341 that is splined on the transmission sleeve 34, and a second motor 16 disposed on the top surface of the cleaning tank 1;

[0059] The second gear 341 is rotatably connected to the connecting cylinder 17 provided on the top surface of the cleaning tank 1, and the second gear 341 is provided with an annular groove for cooperating with the connecting cylinder 17. The output shaft of the second motor 16 is provided with a fourth gear 161 for meshing with the second gear 341.

[0060] The lifting mechanism includes two lead screws 11 disposed on the top surface of the cleaning tank 1 and located on the left and right sides of the drive shaft 3 respectively, and a connecting plate 112 disposed above the lifting plate 113;

[0061] The upper end of the lead screw 11 passes through the lifting plate 113 and is rotatably connected to the connecting plate 112. The lower end of the lead screw 11 is rotatably connected to the top surface of the cleaning tank 1. The lifting plate 113 is threadedly connected to the lead screw 11. A third gear 111 for meshing with the second gear 341 is sleeved on the lead screw 11. The upper end of the transmission sleeve 34 is in contact with the lifting plate 113.

[0062] like Figure 4 As shown, the connecting cylinder 17 is movably connected to the cleaning tank 1, and a connecting ring 171 is fixedly sleeved on the connecting cylinder 17. The top surface of the cleaning tank 1 is provided with a plurality of electric push rods 18 for driving the connecting ring 171 to move up and down to control the spline engagement or disengagement of the second gear 341 and the transmission sleeve 34. The electric push rods 18 adopt existing technology products.

[0063] The drive shaft 3 is vertically provided with a gas channel 38. The bottom surface of the rotating disk 31 is fixedly provided with a main gas chamber 37 that communicates with the gas channel 38. Each cleaning sleeve 32 is rotatably sealed with a gas distribution chamber 371 for supplying gas to the corresponding clamping mechanism. Multiple gas distribution chambers 371 are fixedly connected to the bottom surface of the rotating disk 31, and the main gas chamber 37 is connected to the gas distribution chambers 371 one by one through multiple pipes.

[0064] The inflation mechanism is an airbag 39 fixedly installed on the upper end of the transmission shaft 3 and in contact with the connecting plate 112. The air outlet of the airbag 39 is connected to the gas channel 38, and a one-way valve is provided in the air inlet of the airbag 39. The one-way valve adopts existing technology products, and the one-way valve is connected from the outside to the inside of the airbag 39 in one direction.

[0065] The rotating disk 31 is provided with a first exhaust port 311 that communicates with the main air chamber 37. The first gear 33 is provided with a second exhaust port 331 for connecting the first exhaust port 311 to exhaust by rotating the rotating disk 31. The first exhaust port 311 is provided with a one-way valve. The one-way valve adopts existing technology products and is connected to the outside of the main air chamber 37 in one direction.

[0066] like Figure 5 , 6 As shown, the clamping mechanism includes six sliding holes disposed on the inner wall of the cleaning sleeve 32 and communicating with the corresponding air distribution chamber 371, and a sliding rod 321 slidably sealed in the sliding holes;

[0067] The cleaning tank 1 has eight ultraviolet lamps 12 on its side wall for sterilizing the filter element. The cleaning tank 1 is equipped with a liquid filling pipe 13, and the bottom surface of the cleaning tank 1 is equipped with a discharge port 15 that corresponds to the position of one of the cleaning sleeves 32 by rotating the rotating disk 31. The discharge port 15 is equipped with a feeding mechanism, which adopts a detachable door.

[0068] The working principle of the above device is as follows: In the initial state, the first exhaust port 311 and the second exhaust port 331 are not connected, the electric push rod 18 is in the extended state, and the second gear 341 is engaged with the spline of the transmission sleeve 34.

[0069] Cleaning liquid is added to the cleaning tank 1 through the liquid addition pipe 13, and filter element is added to the cleaning tank 1 through the feed pipe 2. The filter element will fall into the fixing seat 19 through the cleaning sleeve 32, and the air pressure rod in the fixing seat 19 extends to fix the filter element.

[0070] The second motor 16 is started. The second motor 16 drives the second gear 341 to rotate through the fourth gear 161. The second gear 341 drives the transmission sleeve 34 to rotate. The transmission sleeve 34 drives the first gear 33 to rotate, causing the cleaning sleeve 32 to rotate. At the same time, the second gear 341 drives the lead screw 11 to rotate through the third gear 111, causing the lifting plate 113 to move up and down. The lifting plate 113 drives the transmission shaft 3 to move up and down, causing the rotating disk 31 to drive the cleaning sleeve 32 to move up and down to clean the filter element.

[0071] After cleaning, the electric push rod 18 is shortened, causing the spline of the second gear 341 to disengage from the transmission sleeve 34, and the pneumatic rod in the fixed seat 19 is shortened to loosen the filter element.

[0072] When the second motor 16 is started, the transmission sleeve 34 stops rotating. The second motor 16 drives the lead screw 11 to rotate, causing the lifting plate 113 to continue to rise until the air bag 39 is squeezed by the connecting plate 112. The gas in the air bag 39 enters the main air chamber 37 through the gas channel 38, and then enters each sub-air chamber 371 through the main air chamber 37, causing the slide bar 321 to extend under the action of air pressure to clamp the filter element.

[0073] After clamping is completed, as the lifting plate 113 continues to rise, the rotating disk 31 will drive the filter element to rise, so that the filter element does not contact the bottom surface of the cleaning tank 1. Then the first motor 35 is started. The first motor 35 drives the transmission shaft 3 to rotate through the fifth gear 351 and the sixth gear 36, so that the rotating disk 31 rotates 315°. During the rotation of the rotating disk 31, since the toothed ring on the cleaning sleeve 32 meshes with the first gear 33, the cleaning sleeve 32 will drive the filter element to rotate, so that the ultraviolet lamp 12 can perform sterilization treatment on the filter element.

[0074] When the filter element rotates to the discharge port 15 position, the electric push rod 18 can be extended to make the second gear 341 mesh with the spline of the transmission sleeve 34, and the second motor 16 is started. At this time, the lead screw 11 drives the lifting plate 113 to continue to rise, so that the transmission sleeve 34 drives the first gear 33 to rotate, so that the second exhaust port 331 connects with the first exhaust port 311. At this time, the main air chamber 37 exhausts, and the clamping mechanism no longer clamps the filter element.

[0075] At this point, the next cleaning sleeve 32 connects to the feeding pipe 2, and a filter element can be added to the next cleaning sleeve 32. The hatch is opened once to allow the filter element at the discharge port 15 to fall out.

[0076] Example 2

[0077] like Figure 7 , 8As shown, this embodiment is basically the same as embodiment 1, except that the side wall of the rotating disk 31 is provided with eight cleaning blocks 14 for cleaning the ultraviolet lamp 12. The cleaning blocks 14 correspond one-to-one with the position of the ultraviolet lamp 12 and are vertically slidably connected to the sliding groove on the inner wall of the cleaning tank 1.

[0078] The working principle of the cleaning block 14 is as follows: when the rotating disk 31 moves up and down, the rotating disk 31 will drive the cleaning block 14 to move up and down together. During the up and down movement of the cleaning block 14, the ultraviolet lamp 12 will be cleaned to prevent dirt from adhering to the ultraviolet lamp 12.

[0079] Example 3

[0080] like Figure 9 , 10 As shown, this embodiment is basically the same as embodiment 1, except that the feeding mechanism includes a feeding pipe 4 vertically arranged on the bottom surface of the cleaning tank 1 and connected to the discharge port, a rotating cylinder 44 vertically arranged on the bottom surface of the cleaning tank 1 and rotatably connected thereto, and two feeding discs 43 horizontally arranged below the cleaning tank 1. Both feeding discs 43 are fixedly sleeved on the rotating cylinder 44.

[0081] The feeding pipe 4 is composed of a thick pipe 41 and two thin pipes 42 respectively located at the upper and lower ends of the thick pipe 41. The two feeding discs 43 are located at the upper and lower ends of the thick pipe 41 respectively, and the left side of the feeding disc 43 extends into the thick pipe 41 to close the upper and lower ends of the thick pipe 41. The feeding disc 43 is provided with an opening for connecting with the thin pipe 42 by rotating it, and the openings of the two feeding discs 43 are staggered.

[0082] The rotating drum 44 is vertically provided with a slide rod 45 for sliding up and down in coordination with the rotating disk 31. The upper end of the slide rod 45 passes through the bottom surface of the cleaning tank 1 and is fitted with a limiting ring 451. The lower end of the slide rod 45 is threadedly connected to the material feeding disk 43 below. The slide rod 45 is slidably and sealed to the cleaning tank 1, and the limiting ring 451 is connected to the bottom surface of the cleaning tank 1 by a spring.

[0083] A reflux pump 46 is provided below the cleaning tank 1. The input end of the reflux pump 46 is connected to the side wall of the thick pipe 41, and the output end of the reflux pump 46 is connected to the cleaning tank 1 through a liquid infusion pipe. A monitor for monitoring the concentration of the cleaning solution is provided on the liquid infusion pipe. The monitor adopts existing technology products.

[0084] The working principle of the above-mentioned feeding mechanism is as follows: after the filter element rotates to the discharge port 15 position, the clamping mechanism no longer clamps the filter element, and the filter element falls into the upper thin tube 42. When cleaning the filter element in the next cleaning sleeve 32, the rotating disk 31 will move up and down.

[0085] When the rotating disc 31 descends, it squeezes the slide bar 45, causing the slide bar 45 to slide downwards. This causes the feed disc 43 to rotate clockwise under the action of the thread, so that the opening of the upper feed disc 43 connects with the upper thin tube 42. Some cleaning fluid and filter element enter the feed pipe 4. The return pump 46 will return the cleaning fluid in the feed pipe 4 to the cleaning tank 1. At the same time, the monitor will monitor the concentration of the returned cleaning fluid to observe whether cleaning fluid needs to be added. As the feed disc 43 continues to rotate, the opening of the lower feed disc 43 connects with the lower thin tube 42, and the filter element falls out of the feed pipe 4.
