Description

Technical Field

[0001] This utility model relates to the field of cooler circulating water technology, and in particular to a cooler circulating water filtration device. Background Technology

[0002] Coolers play an important role in industrial and commercial sectors and are widely used in the thermal management systems of various equipment, such as power plants, chemical plants, and HVAC systems. Coolers typically dissipate heat through circulating water to maintain the normal operation of the equipment and improve its efficiency. However, during long-term operation, the circulating water system is prone to contamination, leading to water quality deterioration, which reduces the working efficiency of the cooler and may even cause equipment failure. Therefore, a cooler circulating water filtration device is needed.

[0003] In traditional cooler circulating water filtration devices, physical methods such as filter screens are typically used to remove suspended particles and impurities from the water. However, over time, impurities gradually accumulate on the surface of the filter screen, which directly affects filtration efficiency. To maintain good filtration results, users need to perform manual cleaning regularly. This process not only consumes a lot of time and manpower, reducing work efficiency, but also, traditional filter screens are usually installed using bolts and nuts. While this design ensures the stability of the filter screen, the installation and disassembly process is relatively cumbersome in actual operation, requiring the use of tools for fixing and disassembly, increasing the difficulty of operation and the complexity of maintenance, thus reducing the practicality of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling water circulating filter device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cooler circulating water filtration device includes a base, with support frames fixed at both ends of the top of the base. A cooler body is fixed to the inner sidewalls of the two support frames. An outlet and an inlet are fixed to the outer sidewalls of both ends of the cooler body, respectively. A first connecting pipe is fixed to one end of the outlet, and a water pump is installed on the sidewall of the first connecting pipe. A cylinder is fixed to one end of the first connecting pipe, and the first connecting pipe and the cylinder are connected. A second connecting pipe passes through the sidewall of the cylinder, and a cooling device is installed at one end of the second connecting pipe. A third connecting pipe is installed on the outer sidewall of the cooling device, and the third connecting pipe is connected to the cooling device. One end of the third connecting pipe is fixed to the inlet. A cylinder cover is provided at the top of the cylinder. Multiple fixing mechanisms for fixing the cylinder cover are arranged at equal intervals on the outer sidewall of the cylinder. The inner sidewall of the cylinder is provided with… The device includes a second annular plate located between the first and second connecting pipes. A filter screen is fixed to the inner wall of the second annular plate. A limiting mechanism for restricting the second annular plate is provided on the inner wall of the cylinder. Two lifting mechanisms for lifting the second annular plate are symmetrically arranged at the bottom of the cylinder. A cleaning mechanism for cleaning the filter screen is provided on the top of the cylinder cover. A collection mechanism is provided on the outer wall of the cylinder. During use, the cleaning mechanism automatically cleans impurities from the filter screen surface, reducing the need for manual maintenance, saving manpower and time, and improving work efficiency. The limiting and lifting mechanisms simplify the installation and replacement of the filter screen, making operation convenient and reducing maintenance complexity. Users can easily complete maintenance work, improving the practicality of the device.

[0007] Preferably, the limiting mechanism includes a first annular plate, which is fixed to the inner wall of the cylinder. The first annular plate has two symmetrical through holes at its top, and the second annular plate has two symmetrical pillars fixed at its bottom. The two pillars are respectively adapted to the two through holes. The two pillars are inserted into the two through holes until the second annular plate and the first annular plate come into contact. At this time, the two pillars penetrate the bottom of the two through holes to prevent the filter screen from rotating and affecting the subsequent cleaning work.

[0008] Preferably, the fixing mechanism includes an L-shaped plate rotatably connected to the outer wall of the cylinder. A circular groove is formed at the top inner edge of the L-shaped plate, and the groove has a constricted opening. A first circular slider is slidably connected to the inner wall of the circular groove. A circular locking block is fixed to the bottom of the first circular slider, and a pull rod is fixed to the top of the first circular slider. One end of the pull rod passes through the top of the L-shaped plate. A first spring is sleeved on the side wall of the pull rod. A circular hole is formed at the top of the cylinder cover, and the hole matches the circular locking block. By rotating multiple L-shaped plates, the rotation... Simultaneously, pulling multiple levers causes multiple first circular sliders to move upwards along the inner walls of multiple circular grooves until multiple circular blocks retract into the multiple circular grooves. At this point, multiple first springs are compressed. When multiple circular grooves coincide with multiple circular holes, multiple levers are released. Under the reaction of multiple compressed first springs, multiple first circular sliders are pushed to move in the opposite direction, causing multiple circular blocks to enter the multiple circular holes, thus completing the fixing of the cylinder and the cap. Reversing the operation releases the fixing of the cylinder and the cap.

[0009] Preferably, the cleaning mechanism includes a rotating shaft rotatably connected to the bottom center of the inner part of the cylinder cover. A motor is fixed to the top of the cylinder cover, and the output shaft of the motor is fixed to the rotating shaft. Multiple arc-shaped scrapers are fixed at equal intervals in a circular pattern on the side wall of the rotating shaft. The collecting mechanism includes a discharge port, which is opened on the outer wall of the cylinder, and the lower edge of the discharge port is flush with the filter screen. A collecting hopper is fixed on the outer wall of the cylinder near the discharge port, and the collecting hopper is located below the discharge port. The driving motor drives the rotating shaft to rotate, which in turn drives the multiple arc-shaped scrapers to rotate, cleaning the impurities on the surface of the filter screen. Under the action of centrifugal force, the impurities are scraped into the collecting hopper through the discharge port and collected. This eliminates the need for workers to clean the filter screen regularly, saving time and manpower and improving work efficiency.

[0010] Preferably, the lifting mechanism includes a sleeve fixed to the bottom of the cylinder and located directly below the column. A second circular slider is slidably connected inside the sleeve, and a connecting rod is fixed to the top of the second circular slider, with one end of the connecting rod penetrating through the top of the sleeve. A second spring is installed inside the sleeve and located below the second circular slider. When the filter needs to be replaced, the fixing between the cover and the cylinder is released, and the cover is removed from the top of the cylinder, i.e., multiple arc-shaped scrapers and the second annular plate disengage. At this time, under the reaction of the two compressed second springs, the two second circular sliders are pushed to move in opposite directions, which, together with the two connecting rods, pushes the two columns upward, causing the two columns to disengage from the two through holes respectively, until the second annular plate is pushed out of the cylinder. Then, the second annular plate and the filter can be replaced as a whole. The operation is simple, the maintenance complexity is reduced, and the practicality of the device is improved.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. During use, the cleaning mechanism of this device can automatically clean impurities on the surface of the filter screen during the filtration process, reducing the need for manual maintenance, saving manpower and time, and improving work efficiency.

[0013] 2. The design of the limiting and lifting mechanisms simplifies the installation and replacement of the filter screen, making operation convenient and reducing the complexity of maintenance. Users can easily complete maintenance work, thus improving the practicality of the device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1 - Figure 6 A cooling water circulating filter device includes a base 1, with support frames 3 fixed at both ends of the top of the base 1. A cooler body 2 is fixed to the inner sidewall of the two support frames 3. An outlet 4 and an inlet 13 are fixed to the outer sidewalls of both ends of the cooler body 2, respectively. A first connecting pipe 5 is fixed to one end of the outlet 4. A water pump 6 is installed on the sidewall of the first connecting pipe 5. A cylinder 7 is fixed to one end of the first connecting pipe 5, and the first connecting pipe 5 and the cylinder 7 are connected. A second connecting pipe 10 is passed through the sidewall of the cylinder 7. A cooling device 11 is installed at one end of the second connecting pipe 10. A third connecting pipe 12 is installed on the outer sidewall of the cooling device 11, and the third connecting pipe 12 is connected to the cooling device 11. One end of the third connecting pipe 12 is fixed to the inlet 13. A cylinder cover 20 is provided at the top of the cylinder 7. Multiple fixing mechanisms for fixing the cylinder cover 20 are arranged at equal intervals on the outer sidewall of the cylinder 7. The inner sidewall of the cylinder 7 is provided with… A second annular plate 24 is provided, located between the first connecting pipe 5 and the second connecting pipe 10. A filter screen 25 is fixed to the inner wall of the second annular plate 24. A limiting mechanism for limiting the second annular plate 24 is provided on the inner wall of the cylinder 7. Two lifting mechanisms for lifting the second annular plate 24 are symmetrically arranged at the bottom of the cylinder 7. A cleaning mechanism for cleaning the filter screen 25 is provided on the top of the cylinder cover 20. A collection mechanism is provided on the outer wall of the cylinder 7. During use, the design of the cleaning mechanism enables the automatic cleaning of impurities on the surface of the filter screen 25 during the filtration process, reducing the need for manual maintenance, saving manpower and time, and improving work efficiency. The design of the limiting mechanism and the lifting mechanism makes the installation and replacement of the filter screen 25 simple and convenient, reducing the complexity of maintenance. Users can easily complete the maintenance work, improving the practicality of the device.

[0023] Furthermore, the limiting mechanism includes a first annular plate 23, which is fixed to the inner wall of the cylinder 7. The top of the first annular plate 23 has two symmetrical through holes 28. The bottom of the second annular plate 24 has two symmetrical columns 27, which are adapted to the two through holes 28 respectively. The two columns 27 are inserted into the two through holes 28 respectively until the second annular plate 24 and the first annular plate 23 come into contact. At this time, the two columns 27 penetrate the bottom of the two through holes 28 respectively, preventing the filter screen 25 from rotating and affecting the subsequent cleaning work.

[0024] Furthermore, the fixing mechanism includes an L-shaped plate 14, which is rotatably connected to the outer wall of the cylinder 7. A circular groove 15 is formed at the top of the L-shaped plate 14, and the circular groove 15 has a constricted opening. A first circular slider 16 is slidably connected to the inner wall of the circular groove 15. A circular locking block 17 is fixed to the bottom of the first circular slider 16, and a pull rod 18 is fixed to the top of the first circular slider 16. One end of the pull rod 18 passes through the top of the L-shaped plate 14. A first spring 19 is sleeved on the side wall of the pull rod 18. A circular hole 22 is formed at the top of the cylinder cover 20, and the circular hole 22 is adapted to the circular locking block 17. By rotating multiple L-shaped plates 14, while rotating... Pulling multiple levers 18 causes multiple first circular sliders 16 to move upward along the inner walls of multiple circular grooves 15 until multiple circular locking blocks 17 retract into the multiple circular grooves 15. At this time, multiple first springs 19 are compressed. When multiple circular grooves 15 coincide with multiple circular holes 22, the multiple levers 18 are released. Under the reaction of multiple compressed first springs 19, multiple first circular sliders 16 are pushed to move in the opposite direction, so that multiple circular locking blocks 17 enter the multiple circular holes 22. This completes the fixing of cylinder 7 and cylinder cover 20. Reversing the operation releases the fixing of cylinder 7 and cylinder cover 20.

[0025] Furthermore, the cleaning mechanism includes a rotating shaft 32, which is rotatably connected to the bottom center of the inner part of the cylinder cover 20. A motor 21 is fixed to the top of the cylinder cover 20, and the output shaft of the motor 21 is fixed to the rotating shaft 32. Multiple arc-shaped scrapers 33 are fixed in a circular pattern at equal intervals on the side wall of the rotating shaft 32. The collection mechanism includes a discharge port 8, which is opened on the outer wall of the cylinder 7. The lower edge of the discharge port 8 is flush with the filter screen 25. A collection hopper 9 is fixed on the outer wall of the cylinder 7 near the discharge port 8, and the collection hopper 9 is located below the discharge port 8. The drive motor 21 drives the rotating shaft 32 to rotate, which in turn drives the multiple arc-shaped scrapers 33 to rotate, cleaning the impurities on the surface of the filter screen 25. Under the action of centrifugal force, the impurities are scraped into the collection hopper 9 through the discharge port 8 and collected. There is no need for workers to clean the filter screen 25 regularly, saving time and manpower and improving work efficiency.

[0026] Furthermore, the lifting mechanism includes a sleeve 26, which is fixed to the bottom of the cylinder 7 and located directly below the column 27. A second circular slider 29 is slidably connected inside the sleeve 26, and a connecting rod 30 is fixed to the top of the second circular slider 29, with one end of the connecting rod 30 passing through the top of the sleeve 26. A second spring 31 is installed inside the sleeve 26 and is located below the second circular slider 29. When the filter screen 25 needs to be replaced, the fixing between the cylinder cover 20 and the cylinder 7 is released, and the cylinder cover 20 is lifted from the cylinder 7. Once the top of cylinder 7 is removed, the multiple arc-shaped scrapers 33 and the second annular plate 24 disengage. At this point, under the reaction force of the two compressed second springs 31, the two second circular sliders 29 are pushed to move in opposite directions. Together with the two connecting rods 30, the two columns 27 are pushed upward, causing the two columns 27 to disengage from the two through holes 28 respectively, until the second annular plate 24 is pushed out of cylinder 7. Then, the second annular plate 24 and the filter screen 25 can be replaced as a whole. The operation is simple, the maintenance complexity is reduced, and the practicality of this device is improved.

[0027] Working principle: During use, the filter screen 25 is pre-fixed on the inner wall of the second annular plate 24. During installation, the two columns 27 are inserted into the two through holes 28 until the second annular plate 24 and the first annular plate 23 come into contact. At this time, under the action of the two columns 27, the two connecting rods 30 are pushed, causing the two second circular sliders 29 to move downward along the inner walls of the two sleeves 26, thereby compressing the two second springs 31. Then, the cylinder cover 20 is placed on the top of the cylinder 7, and multiple L-shaped plates 14 are rotated. While rotating, multiple pull rods 18 are pulled, causing multiple first circular sliders 16 to move upward along the inner walls of multiple circular grooves 15, until multiple The circular locking blocks 17 retract into the multiple circular sliding grooves 15. At this time, the multiple first springs 19 are all in a compressed state. When the multiple circular sliding grooves 15 coincide with the multiple circular holes 22, the multiple pull rods 18 are released. Under the reaction action of the multiple compressed first springs 19, the multiple first circular sliders 16 are pushed to move in the opposite direction, so that the multiple circular locking blocks 17 enter the multiple circular holes 22. At this time, the multiple arc-shaped scrapers 33 are all in a squeezing state against the second annular plate 24, thus completing the installation work. During filtration, the power switch of the water pump 6 is turned on, driving the water pump 6 to draw the circulating water inside the cooler body 2 into the cylinder 7 through the outlet 4 and the first connecting pipe 5. After filtering out impurities in the water through the filter screen 25, the water passes through the second... The connecting pipe 10 enters the cooling device 11 and is cooled. It then re-enters the cooler body 2 through the third connecting pipe 12 and the inlet 13 for reuse. Simultaneously, the power switch of the motor 21 is turned on, driving the motor 21 to rotate the rotating shaft 32, which in turn rotates multiple arc-shaped scrapers 33 to clean impurities from the surface of the filter screen 25. Under centrifugal force, the impurities are scraped into the collection hopper 9 through the outlet 8 and collected. This eliminates the need for regular cleaning of the filter screen 25, saving time and manpower and improving work efficiency. When the filter screen 25 needs to be replaced, first release the fixing between the multiple circular clips 17 and the multiple circular holes 22, then rotate the multiple L-shaped plates 14 in the opposite direction to allow replacement. Once multiple L-shaped plates 14 are detached from the top of the cylinder cover 20, the fixation between the cylinder cover 20 and the cylinder 7 is released. The cylinder cover 20 is then removed from the top of the cylinder 7, and multiple arc-shaped scrapers 33 and the second annular plate 24 are detached. At this point, under the reaction action of the two compressed second springs 31, the two second circular sliders 29 are pushed to move in opposite directions. Together with the two connecting rods 30, the two columns 27 are pushed upward, causing the two columns 27 to detach from the two through holes 28 respectively, until the second annular plate 24 is pushed out of the cylinder 7. Then, the second annular plate 24 and the filter screen 25 can be replaced as a whole. The operation is simple, and it is convenient to install and replace the filter screen 25, reducing the complexity of maintenance and improving the practicality of this device.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
