Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter with a filter element that is easy to replace. Background Art

[0002] The filter is an indispensable device on the medium conveying pipeline. It is usually installed on the pressure reducing valve, pressure relief valve, and water level valve to facilitate the inlet equipment of other filter equipment. The filter consists of a cylinder, a stainless steel filter screen, a sewage discharge part, a transmission device and an electrical control part. After the water to be treated passes through the sleeve of the filter screen, its impurities are blocked.

[0003] In the existing technology, when the filter element needs to be disassembled and replaced, the relatively complicated disassembly process often requires the operator to have a high level of skills and experience. For people who are not familiar with the equipment, the filter may be damaged or a safety accident may occur due to improper operation. The complicated disassembly process requires more manpower and may require multiple operators to work together, which increases the company's labor costs. Especially when the filter element needs to be replaced frequently, the labor cost will increase significantly; therefore, we propose a filter that is easy to replace the filter element to solve this problem. Utility Model Content

[0004] The purpose of the present invention is to provide a filter that is easy to replace the filter element, so as to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A filter for easy replacement of filter elements, comprising: a mounting plate, two sets of movable plates slidably mounted on one side of the mounting plate, anti-slip clamps fixedly mounted on one side of the two sets of movable plates, a filter body movably abutted between the two sets of anti-slip clamps, an ultrafiltration screen slidably mounted inside the filter body, a pull handle fixedly mounted on the top of the ultrafiltration screen, a filter sealing cover hingedly mounted on the top of the filter body, a water outlet connected to the top of the filter sealing cover, a water inlet connected to the bottom of the filter body, and a connecting rod fixedly mounted on the outside of the filter sealing cover. The bottom of the connecting rod is fixedly installed with a frame, and a U-shaped plate is slidably installed inside the frame, and an insert block is fixedly installed on one side of the U-shaped plate, and a guide rod is fixedly installed on one side of the guide rod, and a return spring is sleeved on the outer side of the guide rod, and a moving block is slidably installed on the outer side of the guide rod, and a handle is fixedly installed on one side of the moving block. An L-shaped fixed block is fixedly installed on one side of the frame, and one end of the L-shaped fixed block is movably plugged into one side of the moving block. Two sets of limit rods are slidably installed inside the frame, and the outer sides of the two sets of limit rods are sleeved with tension springs.

[0007] Preferably, two groups of brackets are fixedly installed on one side of the mounting plate, and two groups of bidirectional screw rods are rotatably installed inside the two groups of brackets. The two groups of movable plates are threadedly connected to the outside of the bidirectional screw rods, and a turntable is rotatably installed on one side of one group of brackets, and the turntable is fixedly installed on one end of the bidirectional screw rod.

[0008] Preferably, one end of the two groups of limiting rods is fixedly mounted on one side of the U-shaped plate, and both ends of the two groups of tension springs are respectively fixedly mounted on one inner wall of the frame and one side of the U-shaped plate.

This uniform fixing method can effectively improve the stability of the filter and ensure the reliability of the filtering effect.

[0013] The utility model has a reasonable structural design. By setting a handle to drive the moving block to move downward in the frame under the restriction of the guide rod, the reset spring contracts, thereby causing the L-shaped fixed block to break away from the lateral displacement restriction of the moving block, and then the handle drives the U-shaped plate to slide leftward in the frame under the restriction of the limit rod, thereby driving the plug-in block to break away from the fixing groove, thereby releasing the fixation of the filter body. The filter body and the filter sealing cover are hinged to each other, so that the filter sealing cover can be opened, so that the handle can be pulled to extract the damaged or aged ultrafiltration filter screen for quick replacement, and the elastic action of the reset spring and the tension spring is used. The filter sealing cover and the filter body can be re-locked with force without external force. Not only can the filter body be quickly released and the sealing cover opened to replace the filter element, but after the replacement is completed, the sealing cover and the filter body can be quickly re-fixed with the help of the elastic force of the return spring and the tension spring without external force, saving operation time. Quick replacement of filter elements means reducing equipment downtime, improving production efficiency or continuity of use. At the same time, simple operation also reduces maintenance costs. No professional personnel are required to perform complex repairs. Ordinary users can also replace the filter element by themselves, extending the service life of the filter.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-4 , a filter for easy replacement of filter elements, comprising: a mounting plate 1, two sets of movable plates 3 are slidably mounted on one side of the mounting plate 1, one side of each set of movable plates 3 is fixedly mounted with an anti-slip clamp 5, a filter body 6 is movably abutted between the two sets of anti-slip clamps 5, an ultrafiltration filter screen 11 is slidably mounted inside the filter body 6, a pull handle 12 is fixedly mounted on the top of the ultrafiltration filter screen 11, a filter sealing cover 7 is hinged on the top of the filter body 6, the top of the filter sealing cover 7 is connected to the water outlet 9, the bottom of the filter body 6 is connected to the water inlet 10, a connecting rod 8 is fixedly mounted on the outside of the filter sealing cover 7, and the connecting rod 8 is fixedly mounted on the outside of the filter sealing cover 7. A frame 14 is fixedly installed at the bottom, and a U-shaped plate 15 is slidably installed inside the frame 14. An insert block 16 is fixedly installed on one side of the U-shaped plate 15, and a guide rod 17 is fixedly installed on one side of the U-shaped plate 15. A return spring 18 is sleeved on the outer side of the guide rod 17, and a moving block 21 is slidably installed on the outer side of the guide rod 17. A handle 23 is fixedly installed on one side of the moving block 21. An L-shaped fixed block 22 is fixedly installed on one side of the frame 14, and one end of the L-shaped fixed block is movably inserted into one side of the moving block 21. Two sets of limit rods 19 are slidably installed inside the frame 14, and the outer sides of the two sets of limit rods 19 are sleeved with tension springs 20.

[0021] In this embodiment, two groups of brackets 2 are fixedly installed on one side of the mounting plate 1, and a bidirectional screw rod 4 is rotatably installed inside the two groups of brackets 2. Two groups of movable plates 3 are threadedly connected to the outside of the bidirectional screw rod 4. A turntable 13 is rotatably installed on one side of one group of brackets 2, and the turntable 13 is fixedly installed on one end of the bidirectional screw rod 4. The movable plate 3 and the anti-slip clamp 5 driven by the bidirectional screw rod 4 can apply uniform force to the filter body 6 from both sides to ensure that the filter will not shake or displace during use. This uniform fixing method can effectively improve the stability of the filter and ensure the reliability of the filtering effect.

[0022] In this embodiment, one end of the two sets of limit rods 19 is fixedly mounted on one side of the U-shaped plate 15, and the two ends of the two sets of tension springs 20 are respectively fixedly mounted on the inner wall of one side of the frame 14 and one side of the U-shaped plate 15. The limit rods 19 can ensure that the U-shaped plate 15 performs accurate linear motion in the frame 14. The limit rods 19 can prevent the U-shaped plate 15 from deflecting, rotating or other irregular movements, ensuring that the insert block 16 can accurately detach from the fixed groove, thereby achieving smooth unlocking of the filter body 6.

[0023] In this embodiment, the two ends of the return spring 18 are respectively fixedly mounted on the inner wall of one side of the U-shaped plate 15 and one side of the moving block 21. Flanges are provided on one side of the water outlet 9 and the water inlet 10. The return spring 18 can provide a certain rebound force for the moving block 21 during operation. When the handle 23 is pulled downward to drive the moving block 21 to move downward under the restriction of the guide rod 17, the return spring 18 is compressed; and when the operation is completed and the initial state needs to be restored, the elastic force of the return spring 18 can assist the moving block 21 to return to its original position, making the operation smoother and more convenient.

[0024] In this embodiment, a slot is provided on one side of the movable block 21, and the L-shaped fixed block 22 is movably inserted into the slot. A fixed groove is provided on the outer side of the filter body 6, and the insert block 16 is movably inserted into the fixed groove. The cooperation between the slot and the L-shaped fixed block 22 and the cooperation between the insert block 16 and the fixed groove can achieve precise positioning, ensure that the various components of the filter are in the correct position, and improve the stability of the overall structure.

[0025] In this embodiment, two sets of slide rails are provided on one side of the mounting plate 1, and the two sets of movable plates 3 are slidably installed in the corresponding slide rails. The slide rails provide a clear moving path for the movable plates 3, ensuring that the movable plates 3 always move in a predetermined direction during the movement. This makes the movement of the movable plates 3 more precise, avoiding operational errors or equipment damage caused by directional deviation.

[0026] When the filter is in use, the two-way screw rod 4 is driven to rotate in the bracket 2 by rotating the turntable 13, and then the movable plate 3 is driven to move relatively in the slide groove, thereby driving the anti-slip clamp 5 to fix the filter body 6. The movable plate 3 and the anti-slip clamp 5 driven by the two-way screw rod 4 can apply force to the filter body 6 evenly from both sides to ensure that the filter body 6 will not shake or displace during use. This uniform fixing method can effectively improve the stability of the filter body 6 and ensure the reliability of the filtering effect. By pulling the handle 23 downward, the movable block 21 is driven to move downward in the frame 14 under the restriction of the guide rod 17, and the return spring 18 is contracted, thereby causing the L-shaped fixed block 22 to break away from the lateral displacement restriction of the movable block 21. By pulling the handle 23 to the left again, the U-shaped plate 15 is driven to slide leftward in the frame 14 under the restriction of the limit rod 19, thereby driving the inserting block 16 to break away from the fixing groove, thereby releasing the filter. The filter body 6 is fixed by the mutual hinge between the filter body 6 and the filter sealing cover 7, so that the filter sealing cover 7 can be opened, so that the damaged or aged ultrafiltration filter screen 11 can be pulled out by pulling the handle 12 for quick replacement. Under the elastic force of the reset spring 18 and the tension spring 20, the filter sealing cover 7 and the filter body 6 can be re-locked without external force, which not only can quickly release the fixation of the filter body 6 and open the sealing cover to replace the filter element, but also after the replacement is completed, with the help of the elastic force of the reset spring 18 and the tension spring 20, the sealing cover and the filter body 6 can be quickly re-fixed without external force, saving operation time. Quick replacement of filter elements means reducing equipment downtime, improving production efficiency or continuity of use. At the same time, simple operation also reduces maintenance costs. There is no need for professionals to perform complex repairs. Ordinary users can also replace the filter element by themselves, extending the service life of the filter.
