Description

Technical Field

[0001] This application relates to the field of membrane filter technology, and more particularly to a membrane filter for removing colloids. Background Technology

[0002] A membrane filter is a device that uses a semi-permeable membrane to separate solid substances or dissolved substances from liquids or gases. Membrane filters are widely used in water treatment, chemical, food and beverage, pharmaceutical, and wastewater treatment industries, and are characterized by high-efficiency filtration, energy saving, and environmental friendliness.

[0003] Existing technologies, such as the utility model patent with publication number CN204841424U, disclose a side-mounted membrane housing filter. This patent employs a membrane housing, a top flat-head assembly, a filter element, a filter element sealing ring, and a bottom flat-head assembly. The membrane housing has an inlet and an outlet on its upper and lower sides, respectively. The top flat-head assembly is installed above the inlet and includes an end cap, a top flat head, a top sealing ring, a stainless steel pressure strip, several hexagonal screws, and a push rod. The filter element includes an end cap and a flat head, with a handle on the end cap and a push rod resting on the handle. The filter element sealing ring is installed below the inlet and has a step on its inner wall, through which the end cap is suspended. The bottom flat-head assembly is installed below the outlet and includes an end cap, a bottom flat head, a stainless steel pressure strip, a fixing rib, and several hexagonal screws.

[0004] The inventors discovered in daily use that in existing technologies, due to the deep depth of the filter, it is difficult to remove and replace the filter element after installation. Moreover, filter element replacement is inconvenient, and operators may need more time and effort to complete the maintenance work, making operation and maintenance more complex and cumbersome. Filter elements may become damaged or clogged during long-term use and cannot be easily replaced, which may lead to reduced filtration effect, or even damage to the equipment or unstable operation, affecting the overall system performance. If the filter element cannot be replaced in time for a long period of time, it will affect the working efficiency of the membrane filter, resulting in poor filtration effect, or even aggravating the pollution or clogging of the membrane surface, shortening the service life of the equipment. This problem can be solved by setting up auxiliary structures. Utility Model Content

[0029] The specific settings and functions of auxiliary structure 7 and installation structure 8 will be explained in detail below.

[0030] Reference Figures 3 to 6As shown in this embodiment: the inner wall of the filter element 6 is provided with an auxiliary structure 7, which includes a fixing ring 705. The fixing ring 705 is fixedly connected to the filter element 6. A plurality of connecting plates 709 are fixedly connected to the inner wall of the filter element 6.

The two ends of the top spring 710 are fixedly connected to the circular block 713 and the circular plate 712 respectively. The upper end of the connecting pipe 701 is fixedly connected to a sealing gasket 715. The sealing gasket 715 is slidably connected to the sliding rod 702. When the filter element 6 needs to be installed, first pull the connecting pipe 701 to move it. The connecting pipe 701 drives the circular plate 712 to move, and the circular plate 712 drives the elastic plate 706 to move. Then, the circular plate 712 is inserted between the fixing plate 708 and the fixing ring 705. The fixing ring 705 squeezes and contracts the elastic plate 706. After moving to the appropriate position, the elastic plate 706 is stretched and inserted into the slot 707 for fixation. Then, pull the slide rod 702 to move the filter element 6 into the filter canister 5. Then, the canister cover squeezes the slide rod 702. The slide rod 702 drives the circular block 713 to slide on the inner wall of the limiting groove 714. The circular block 713 drives the top spring 710 to contract. When the filter element 6 needs to be removed, open the canister cover and stretch the top spring 710 to push out the slide plate. Then, pull the slide rod 702 to remove the filter element 6. The upper end of the slide rod 702 is fixedly connected to the handle 703, and the cross-section of the handle 703 is circular. When the slide bar 702 needs to be pulled, the handle 703 can be pulled directly. The handle 703 moves the slide bar 702, making it easier to move. Several auxiliary grooves 704 are evenly distributed on the arc surfaces at both ends of the handle 703. The auxiliary grooves 704 increase the friction between the hand and the handle 703, preventing slippage when pulling. A positioning rod 711 is fixedly connected inside the limiting groove 714, and the positioning rod 711 is slidably connected to the slide bar 702. The positioning rod 711 limits the slide bar 702, preventing it from shifting during use and improving its sliding stability. A top spring 710 is fitted onto the arc surface of the positioning rod 711, which is made of stainless steel.The positioning rod 711 limits the top spring 710 to prevent deformation during use and improves the service life of the top spring 710. The elastic plate 706 has a rectangular cross-section and is made of elastic steel plate.

[0031] Reference Figure 7 and Figure 8 As shown in this embodiment: the mounting structure 8 includes two slide rails 82, which are fixedly connected to the bracket 3. A slider 87 is slidably connected to the inner wall of the slide rail 82. A connecting rod 84 is fixedly connected to the upper surface of the slider 87. A pressing plate 81 is fixedly connected to one end of the two connecting rods 84 that are close to each other. A spring 83 is provided inside the slide rail 82. The two ends of the spring 83 are fixedly connected to the slider 87 and the slide rail 82 respectively. A connecting plate 85 is fixedly connected to the lower surface of the slider 87. A screw 86 is threadedly connected to the inner wall of the connecting plate 85. The screw 86 abuts against the slide rail 82. The pressing plate 81 abuts against the control box 4. When the control box 4 needs to be installed, the pressing plate 81 is pulled to move it. The pressing plate 81 moves the connecting rod 84, which in turn moves the slider 87. The slider 87 slides on the inner wall of the slide rail 82, which in turn stretches the spring 83. The slider 87 then moves the connecting plate 85, which in turn moves the screw 86. The control box 4 is then placed between the pressing plate 81 and the bracket 3. The pressing plate 81 is then released, and the spring 83 retracts, causing the pressing plate 81 to be fixed. The screw 86 is then tightened to fix it in place. An anti-slip pad 89, which is a rubber pad, is fixedly connected to the end of the screw 86 near the slide rail 82. The anti-slip pad 89 increases the friction between the screw 86 and the slide rail 82, preventing the screw 86 from sliding when it comes into contact with the slide rail 82. A limit rod 88 is fixedly connected inside the slide rail 82. The limit rod 88 is slidably connected to the slider 87, and the spring 83 is fitted onto the arc surface of the limit rod 88. The limiting rod 88 can limit the spring 83, preventing deformation during use and improving its service life. The connecting rod 84 has an "L"-shaped cross-section and is made of stainless steel. The stainless steel material increases the service life of the connecting rod 84 and prevents it from corroding during use.

[0032] Working principle: When the filter element 6 needs to be installed, first pull the connecting pipe 701 to move it. The connecting pipe 701 moves the circular plate 712, which in turn moves the elastic plate 706. Then, the circular plate 712 is inserted between the fixing plate 708 and the fixing ring 705. The fixing ring 705 compresses and contracts the elastic plate 706. After moving to the appropriate position, the elastic plate 706 stretches and locks into the slot 707 for fixation. Then, pull the sliding rod 702 to load the filter element 6 into the filter canister 5. The canister cover then compresses the sliding rod 702, causing the sliding rod 702 to slide the circular block 713 along the inner wall of the limiting groove 714. The circular block 713 causes the top spring 710 to retract. When the filter element 6 needs to be removed... Open the can lid to stretch the top spring 710, causing the slide plate to be pushed out. Then pull the slide rod 702 to remove the filter element 6. When it is necessary to pull the slide rod 702, you can directly pull the handle 703. The handle 703 moves the slide rod 702, making it easier to move. The auxiliary groove 704 can increase the friction between the hand and the handle 703, preventing slippage when pulling the handle 703. The positioning rod 711 can limit the slide rod 702, preventing it from deviating during use and improving the stability of the slide rod 702. The positioning rod 711 limits the top spring 710, preventing it from deforming during use and improving its service life.

[0033] When the control box 4 needs to be installed, the pressing plate 81 is pulled to move it. The pressing plate 81 drives the connecting rod 84 to move, and the connecting rod 84 drives the slider 87 to move. The slider 87 slides on the inner wall of the slide rail 82. The slider 87 drives the spring 83 to stretch, and the slider 87 drives the connecting plate 85 to move. The connecting plate 85 drives the screw 86 to move. Then, the control box 4 is placed between the pressing plate 81 and the bracket 3. Then, the pressing plate 81 is released, and the spring 83 retracts to fix the pressing plate 81. Then, the screw 86 is tightened to fix it. The anti-slip pad 89 can increase the friction between the screw 86 and the slide rail 82, preventing the screw 86 from sliding when it abuts against the slide rail 82. The limit rod 88 can limit the spring 83 to prevent the spring 83 from deforming during use and improve the service life of the spring 83. The stainless steel material can increase the service life of the connecting rod 84 and prevent the connecting rod 84 from rusting during use.
