Description

Technical Field

[0001] This utility model relates to the field of filter cloth technology, specifically a filter cloth tensioning device. Background Technology

[0002] Filter cloth is an important industrial filtration material, usually woven from synthetic or natural fibers. It has porosity and good filtration performance. It is mainly used in solid-liquid separation processes, allowing liquids or gases to pass through while retaining solid particles. Filter cloth has a wide range of applications, covering multiple fields such as chemical, food processing, pharmaceutical, and environmental protection. Its selection depends on factors such as filtration accuracy, flow rate, and media characteristics. Filter cloths come in various materials, pore sizes, and structures. Different materials and structures of filter cloths are suitable for different filtration needs, and the selection can be made according to the filtration accuracy and throughput requirements.

[0003] In existing filter cloths, when filtering materials, they are usually fixed inside the material filtration device, allowing the material to fall from top to bottom. Solid impurities in the material remain on the filter cloth, while liquids pass through it. A filter cloth tensioning device is needed in this process to ensure the filter cloth maintains appropriate tension during filtration, optimizing filtration efficiency and preventing the filter cloth from loosening or shifting during operation, thus ensuring stable filtration. However, the tensioning method typically involves squeezing the filter cloth. After use, material can easily accumulate at the squeezing points, which can affect the filtration effect and hinder the use of the filter cloth tensioning device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a new technical solution: a filter cloth tensioning device, including a mounting frame 1, two adjusting screws 2 are rotatably mounted on the upper surface of the mounting frame 1, the lower ends of the two adjusting screws 2 are rotatably extended to the bottom of the mounting frame 1, the two adjusting screws 2 are threadedly connected to the mounting frame 1, and U-shaped plates 3 are rotatably mounted on the lower surface of the two adjusting screws 2, and squeezing rollers 4 are rotatably mounted on the inner wall of the two U-shaped plates 3.

[0024] The rotating mechanism is located inside the U-shaped plate 3. The rotating mechanism includes two driven wheels 5 and two driving wheels 6. The two vertical plates of the U-shaped plate 3 are each provided with a first mounting groove 7. The front and rear ends of the extrusion roller 4 are rotatably inserted into the interior of the two first mounting grooves 7. The two driven wheels 5 are respectively rotatably mounted on the front and rear ends of the extrusion roller 4. The upper ends of the two first mounting grooves 7 are rotatably mounted with connecting rods 8. The two driving wheels 6 are respectively rotatably mounted on the outer surfaces of the two connecting rods 8. The outer surfaces of the two driven wheels 5 and the outer surfaces of the two driving wheels 6 are rotatably sleeved with transmission belts 9. The driven wheels 5 on the front side and the driving wheels 6 on the rear side are respectively connected by two transmission belts 9.

[0025] Furthermore, the rotating mechanism also includes an extrusion plate 10, which is fixedly mounted on the outer surface of the extrusion roller 4.

[0026] Furthermore, there are two rotating mechanisms, which are respectively installed in the two U-shaped plates 3.

[0027] Furthermore, by driving two extrusion rollers 4 to rotate through two drive motors 12, the two extrusion rollers 4 drive two extrusion plates 10 to beat and squeeze the filter cloth. This can cause the material on both sides of the filter cloth to move closer to the middle under the action of vibration, preventing the material accumulated on both sides from affecting the use of the filter cloth. It can also vibrate most of the material on the filter cloth to the middle of the filter cloth, reducing the difficulty of cleaning the filter cloth for the staff and improving the efficiency of the device.

[0028] Furthermore, each of the two U-shaped plates 3 has a second mounting groove 11 inside, and two drive motors 12 are fixedly installed inside each of the two second mounting grooves 11. The near ends of the two connecting rods 8 on the left and the near ends of the two connecting rods 8 on the right are rotated through into the corresponding second mounting grooves 11. The four connecting rods 8 are fixedly connected to the output ends of the corresponding drive motors 12 respectively.

[0029] Furthermore, the upper surface of the mounting bracket 1 is provided with four sliding holes 13, and each of the four sliding holes 13 is slidably installed with a limit rod 14. The four limit rods 14 are divided into two groups and are fixedly connected to the two U-shaped plates 3 respectively.

[0030] Furthermore, the upper surfaces of the two U-shaped plates 3 are provided with convex circular grooves 15, and convex circular rods 16 are rotatably installed inside the two convex circular grooves 15. The two convex circular rods 16 are respectively fixedly connected to the two adjusting screws 2.

[0031] Furthermore, when using this device, it is installed inside the material filtration device and positioned above the filter cloth. Then, the two adjusting screws 2 are rotated, causing them to move downwards. Simultaneously, the U-shaped plates 3 connected to their lower ends move downwards. Two limiting rods 14 prevent the U-shaped plates 3 from shifting during movement, causing the two U-shaped plates 3 to drive the two rotatably mounted squeezing rollers 4 on their inner walls downwards, squeezing and tensioning the filter cloth below. During use, if material accumulates on both sides of the filter cloth, the two adjusting screws 2 can be rotated again to move the two squeezing rollers 4 upwards. After moving a certain distance, the two drive motors 12 can be activated, causing the two drive motors 12 to drive the two rollers fixed to their output ends. The connecting rods 8 are rotated, and the rotation of the four connecting rods 8 drives the drive wheels 6 fixedly connected to them to rotate. The two drive wheels 6 on the left and the two drive wheels 6 on the right drive the corresponding driven wheels 5 to rotate through the corresponding transmission belts 9, thereby driving the two extrusion rollers 4 to rotate. The extrusion plates 10 fixedly installed on the outer surface of the two extrusion rollers 4 rotate and move in the middle position of the device. After the two extrusion plates 10 rotate, they can beat and squeeze the filter cloth below the device, so that the material pushed on both sides of the filter cloth moves closer to the middle. Then, the filter cloth can be cleaned or the two adjusting screws 2 can be rotated again to make the two extrusion rollers 4 squeeze and tighten the filter cloth again, which facilitates the cleaning and use of the filter cloth by the staff.
