Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to an industrial filter with a convenient filter element replacement mechanism. Background Technology

[0002] In modern industrial production processes, industrial filters are widely used in chemical, food, pharmaceutical, and environmental protection fields. They intercept impurities and particulate matter in fluids through filter elements to ensure the smooth operation of the production process and the stability of product quality. With the continuous expansion of industrial production scale and the increasing refinement of production processes, higher requirements are placed on the performance and ease of maintenance of industrial filters.

[0003] Existing industrial filters generally have some problems with filter element replacement. Some filters are integrated designs, and some use complex sealing structures and installation methods. Filter element replacement requires operators to use professional tools for disassembly, which is not only cumbersome and time-consuming, but also prone to damaging other parts of the filter due to improper operation during disassembly, increasing maintenance costs. In addition, the filter element has a certain height when disassembling, which increases the complexity of operation when disassembling manually.

[0004] According to the patent application published on the Internet, an industrial filter with easy-to-replace filter element (authorization announcement number: CN220736529U) is described as including a "shell, water inlet pipe" etc., to achieve filtration.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This industrial filter, designed for easy cartridge replacement, utilizes a housing and inlet pipe for filtration. However, during use, when cartridge replacement is required, operators manipulate two spring pins to separate the mounting sleeve from the housing, then pull the sleeve to remove the cartridge and other components. Disassembling the cartridge from the front of the housing not only fails to guarantee the housing's seal, potentially causing leakage during filtration, but also increases the complexity of manual disassembly due to the cartridge's height. Therefore, this filter requires improvement. Utility Model Content

[0007] The purpose of this invention is to provide an industrial filter with a convenient filter element replacement mechanism to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an industrial filter with convenient filter element replacement, including a support frame, a filtering mechanism is provided inside the support frame, and a fixing mechanism is provided on the right side of the filtering mechanism;

[0009] The filtration mechanism includes a filter body, which is fixedly connected to the inner side of a load-bearing frame. A drain pipe is fixedly connected to the bottom of the filter body. A mounting base is fixedly connected to the inner side of the filter body. A filter element is slidably connected inside the mounting base. A fixing ring is fixedly connected to the outer periphery of the filter element and is inserted into the top of the mounting base. A fixing frame is fixedly connected to the rear side of the filter body. A limit frame is fixedly connected to the inner side of the fixing frame. A cylinder is fixedly connected to the top of the fixing frame. A sealing cover is fixedly connected to the bottom of the cylinder. The sealing cover is located on the top of the filter body. A water inlet pipe is fixedly connected to the top of the sealing cover. A connecting shaft is fixedly connected to the rear side of the sealing cover. A connecting bracket is slidably connected inside the sealing cover. The connecting bracket is located on the right side of the filter element and has a fixing shaft threaded inside.

[0010] Preferably, the water inlet pipe is located at the top of the filter element, the bottom of the sealing cover is in contact with the top of the filter body, and the left side of the connecting bracket is in contact with the right side of the filter element, so that the top of the filter body can be sealed through the sealing cover.

[0011] Preferably, the connecting shaft is slidably connected inside the limiting frame, and the left side of the fixed shaft is threadedly connected inside the filter element, which facilitates the stability between the filter element and the connecting frame under the action of the fixed shaft.

[0012] Preferably, there are two sets of connecting frames and fixed shafts, which are symmetrically distributed on the left and right sides of the bottom of the sealing cover. This arrangement of two sets further ensures the stability between the connecting frames and fixed shafts, and also facilitates installation and disassembly.

[0013] Preferably, the top of the mounting base is provided with a fixing groove, and the fixing ring is inserted into the fixing groove, so that the filter element is in a stable state in the mounting base under the action of the fixing ring, thereby ensuring the stability of the filter element.

[0014] Preferably, the fixing mechanism includes a concave frame, which is fixedly connected to the right side of the filter body. A rotating frame is rotatably connected to the inner side of the concave frame. A threaded rod is threadedly connected inside the rotating frame. A knob is fixedly connected to the top of the threaded rod. A disc is fixedly connected to the periphery of the threaded rod. A pressure plate is rotatably connected to the periphery of the disc. The pressure plate is disposed on the top of the sealing cover. An insert rod is fixedly connected to the bottom of the pressure plate.

[0015] Preferably, the bottom of the pressure plate is in contact with the top of the sealing cover, and the insert rod is inserted into the inside of the sealing cover, which facilitates the fixing of the sealing cover under the action of the pressure plate and the insert rod, and also facilitates installation and disassembly.

[0016] Compared with the prior art, this utility model provides an industrial filter with convenient filter element replacement, which has the following beneficial effects:

[0017] 1. This industrial filter with easy-to-replace filter element features a filtration mechanism. When filtration is required during industrial production, the filter element is initially positioned by inserting a fixing ring into the fixing groove on the top of the mounting base. When filter element replacement is needed, a cylinder lifts the sealing cover, pulling the filter element out of the mounting base. Once the filter element is fully positioned on top of the filter body, the filter element can be held and the fixing shaft inside the connecting bracket can be unscrewed to disconnect the filter element from the sealing cover, allowing for disassembly, replacement, and cleaning. This design significantly shortens filter element replacement time, reduces manual maintenance costs, and improves the maintenance efficiency of industrial filtration equipment. The sealing cover, under the action of the cylinder, fits tightly against the top of the filter body, forming a good seal and preventing liquid leakage during filtration. Two symmetrically distributed connecting brackets and fixing shafts ensure stable fixation of the filter element.

[0018] 2. This industrial filter with easy filter element replacement, through a fixed mechanism, allows the rotating frame to rotate inside the concave frame when the filter body is filtering and the sealing cover is sealing the top of the filter body. This rotation drives the threaded rod and pressure plate to rotate, positioning the pressure plate at the top of the sealing cover. At this point, the knob can be turned to rotate the threaded rod and the disc. Since the pressure plate is connected to the outer periphery of the disc, the disc moves the pressure plate up and down. The operator can then hold the pressure plate and move the insertion rod vertically downwards until the bottom of the pressure plate contacts the top of the sealing cover, and the insertion rod is inserted into the inside of the sealing cover, thus ensuring the stability of the sealing cover.

[0030] This utility model provides the following technical solution:

[0031] Example 1

[0032] Please see Figure 1-7 This utility model provides a technical solution: an industrial filter with convenient filter element replacement, including a support frame 1, a filter mechanism 2 arranged inside the support frame 1, and a fixing mechanism 3 arranged on the right side of the filter mechanism 2;

[0033] The filter mechanism 2 includes a filter body 21, which is fixedly connected to the inner side of the support frame 1. A drain pipe 22 is fixedly connected to the bottom of the filter body 21. A mounting base 28 is fixedly connected to the inner side of the filter body 21. A filter element 29 is slidably connected inside the mounting base 28. A fixing ring 292 is fixedly connected to the outer periphery of the filter element 29 and is inserted into the top of the mounting base 28. A fixing frame 23 is fixedly connected to the rear side of the filter body 21. A limit frame 24 is fixedly connected to the inner side of the fixing frame 23. A cylinder 25 is fixedly connected to the top of the fixing frame 23. A sealing cover 26 is fixedly connected to the bottom of the cylinder 25. The sealing cover 26 is located on the top of the filter body 21. A water inlet pipe 27 is fixedly connected to the top of the sealing cover 26. A connecting shaft 291 is fixedly connected to the rear side of the sealing cover 26. A connecting bracket 293 is slidably connected inside the sealing cover 26. The connecting bracket 293 is located on the right side of the filter element 29. A fixing shaft 294 is threadedly connected inside the connecting bracket 293.

[0034] The inlet pipe 27 is located at the top of the filter element 29, the bottom of the sealing cover 26 is in contact with the top of the filter body 21, and the left side of the connecting bracket 293 is in contact with the right side of the filter element 29, so that the top of the filter body 21 can be sealed through the sealing cover 26. The connecting shaft 291 is slidably connected to the inside of the limiting frame 24, and the left side of the fixed shaft 294 is threadedly connected to the inside of the filter element 29, so as to ensure the stability between the filter element 29 and the connecting bracket 293 under the action of the fixed shaft 294.

[0035] Two sets of connecting brackets 293 and fixed shafts 294 are provided. The two sets of connecting brackets 293 and fixed shafts 294 are symmetrically distributed on the left and right sides of the bottom of the sealing cover 26. By setting two sets, the stability between the connecting brackets 293 and fixed shafts 294 can be further guaranteed. At the same time, it is easy to install and disassemble. The top of the mounting base 28 has a fixing groove, and the fixing ring 292 is inserted into the fixing groove. Under the action of the fixing ring 292, the filter element 29 is kept in a stable state in the mounting base 28, thereby ensuring the stability of the filter element 29.

[0036] Example 2

[0037] Please see Figure 1-7 Furthermore, based on Embodiment 1, the fixing mechanism 3 includes a concave frame 31, which is fixedly connected to the right side of the filter body 21. A rotating frame 32 is rotatably connected to the inner side of the concave frame 31. A threaded rod 34 is threadedly connected inside the rotating frame 32. A knob 33 is fixedly connected to the top of the threaded rod 34. A disc 36 is fixedly connected to the outer periphery of the threaded rod 34. A pressure plate 35 is rotatably connected to the outer periphery of the disc 36. The pressure plate 35 is located on the top of the sealing cover 26. An insertion rod 37 is fixedly connected to the bottom of the pressure plate 35.

[0038] The bottom of the pressure plate 35 is in contact with the top of the sealing cover 26, and the insertion rod 37 is inserted into the inside of the sealing cover 26, which facilitates the fixing of the sealing cover 26 under the action of the pressure plate 35 and the insertion rod 37, and also facilitates installation and disassembly.

[0039] In actual operation, when this device is used, and when filtration is required through the filter body 21 in industrial production, the sealing cover 26 is first placed at the top of the filter body 21, and the filter element 29 is placed at the middle of the bottom of the sealing cover 26. At this time, the two sets of connecting brackets 293 slide inside the sealing cover 26, and the two sets of connecting brackets 293 move to the left and right sides of the filter element 29. The connecting brackets 293 and the filter element 29 are fixed by the fixing shaft 294 to ensure the stability of the filter element 29. After the fixing is completed, the sealing cover 26 can be moved by the cylinder 25, and the sealing cover 26 can drive the connecting shaft 291 to slide inside the limit frame 24.

[0040] When the sealing cover 26 moves to the top of the filter body 21, it will cause the filter element 29 to slide and connect inside the mounting base 28, and the fixing ring 292 will be inserted into the top of the mounting base 28, so that the top of the filter body 21 can be sealed and the filter element 29 can be installed.

[0041] Simultaneously, the rotating frame 32 rotates inside the concave frame 31, causing the rotating frame 32 to drive the threaded rod 34 and the pressure plate 35 to rotate, so that the pressure plate 35 is at the top of the sealing cover 26. At this time, the knob 33 can be turned to drive the threaded rod 34 to rotate the disc 36. Since the pressure plate 35 is rotatably connected to the outer periphery of the disc 36, the disc 36 can drive the pressure plate 35 to move up and down. The operator holds the pressure plate 35 and moves the insertion rod 37 vertically downward until the bottom of the pressure plate 35 contacts the top of the sealing cover 26, and the insertion rod 37 is inserted into the inside of the sealing cover 26, thus ensuring the stability of the sealing cover 26.

[0042] At this time, external sewage can be transported to the filter body 21 through the inlet pipe 27, and the filter will be filtered under the action of the filter element 29. The filtered sewage will be discharged through the drain pipe 22.

[0043] When the filter element needs to be replaced, the pressure plate 35 and the insertion rod 37 are released from their limiting position on the sealing cover 26. The sealing cover 26 is then lifted by the cylinder 25, and the filter element 29 is pulled out from the mounting base 28. When the filter element 29 is completely on top of the filter body 21, the filter element 29 is held in hand, and the fixing shaft 294 inside the connecting bracket 293 is unscrewed to disconnect the filter element 29 from the sealing cover 26. This allows for the disassembly, replacement, and cleaning of the filter element 29. This design greatly shortens the filter element replacement time, reduces manual maintenance costs, and improves the maintenance efficiency of industrial filtration equipment.
