Description

Technical Field

[0001] This utility model relates to the field of industrial filtration technology, and in particular to a quick-assembly environmentally friendly industrial filter cloth. Background Technology

[0002] Industrial filter cloth is an indispensable filtration material in industrial production. It is widely used in industries such as chemical, metallurgy, food, and environmental protection. It is mainly used in processes such as solid-liquid separation and gas filtration. Traditional industrial filter cloth usually adopts an integral structure, which requires the filter cloth to be cut to a specific size and fixed on the filtration equipment during installation.

[0003] Filter cloth plays an important role in solid-liquid separation. In solid-liquid separation, equipment such as filter presses are often used. The filter cloth is connected by filter plates. However, the traditional connection method of filter plates mostly relies on bolts or welding. This connection method is prone to leakage, complicated installation, inconvenient maintenance, and easy damage to the filter plates. In addition, the filter plates and filter cloth are mostly fixed by bolts or clips, which can easily cause the filter cloth to shift or fall off.

[0004] Therefore, those skilled in the art have provided a quick-assembly environmentally friendly industrial filter cloth to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems of leakage, cumbersome installation, inconvenient maintenance, and easy displacement or detachment of filter cloths caused by traditional industrial filter cloth connection methods, this utility model provides a quick-assembly environmentally friendly industrial filter cloth.

[0006] This utility model provides a quick-assembly environmentally friendly industrial filter cloth, which adopts the following technical solution:

[0007] A quick-assembly environmentally friendly industrial filter cloth includes a filter plate, with the filter cloth disposed on the top of the filter plate. A fixing mechanism is fixedly connected to the surface of the filter plate, and locking mechanisms are fixedly connected to both sides of the filter plate. The fixing mechanism includes a lead screw, one side of which is movably connected to the filter plate via a bearing, and the other side of which penetrates the inner cavity of the filter plate and extends to the surface of the filter plate. A sliding sleeve is threaded onto the surface of the lead screw, and a toothed plate is fixedly connected to one side of the sliding sleeve. A gear meshes with the top of the toothed plate, and a rotating rod is fixedly connected to the inner cavity of the gear. Mounting plates are movably connected to both sides of the rotating rod via bearings. The bottom of the mounting plate is fixedly connected to the filter plate, and a clamping plate is fixedly connected to the top of the rotating rod. The locking mechanism includes a locking block, both sides of which are movably connected to the filter plate. A limit rod is movably connected to the surface of the locking block, and a limit rod has a notch on one side. The card slot has a spring on one side, which is fixedly connected to the filter plate. A push rod is located on the other side of the card block, movably connected to the filter plate. The filter plate is circular, allowing the force to be evenly distributed across the circumference when under pressure. This ensures better structural integrity under high pressure, reducing the possibility of breakage, deformation, and other damage, thus extending the filter plate's service life. Four fixing mechanisms are used to prevent excessive pressure at a single point from causing filter cloth deformation or breakage. A slider is fixedly connected to the bottom of the toothed plate, and a groove is provided at the bottom of the slider. The bottom of the slider slides into the groove, limiting the range of motion of the toothed plate. Two mounting plates are used to fix the rotating rod. Movable grooves are provided on both sides of the card block, and both sides slide into the movable grooves, limiting the card block's movement.

[0008] Optionally, a rotating handle is provided on one side of the filter plate, and one side of the rotating handle is fixedly connected to the lead screw. The rotating handle allows the operator to drive the entire fixing mechanism to fix the filter cloth by rotating the handle, thus improving the convenience of the fixing mechanism.

[0009] Optionally, a first toothed block is fixedly connected to one side of the clamping plate, and a second toothed block is fixedly connected to the surface of the filter plate. There are multiple first toothed blocks and multiple second toothed blocks. After the filter cloth is fixed, the first toothed block and the second toothed block are in a mutually interlocking state, which increases the friction between the filter cloth and the filter cloth and improves the stability of the fixing mechanism.

[0010] Optionally, a connecting plate is provided on one side of the filter plate, and the connecting plate is fixedly connected to the push rod on one side. The connection plate allows the filter plate to be removed by pushing the connecting plate from the outside, thus improving the convenience of the locking mechanism.

[0011] Optionally, a limiting plate is provided on one side of the card block. One side of the limiting plate is fixedly connected to the push rod. There are two limiting plates. Both sides of the limiting plates are slidably connected to the inner cavity of the filter plate, which can limit the range of motion of the push rod and prevent it from leaving the inner cavity of the filter plate.

[0012] Optionally, the filter plate has a slot on one side of its inner cavity, a guide hole on one side of the slot, and a water outlet on the other side of the slot. There are two slots located on both sides of the fixing mechanism, and there are multiple guide holes and water outlets, which are used to discharge the liquid generated during the filtration process.

[0013] Optionally, a rubber pad is provided at the bottom of the filter plate, and handles are fixedly connected to both sides of the filter plate. The rubber pad can increase the sealing between the filter plates and play a buffering role to a certain extent, reducing the impact of collisions on the filter plates. The handles are used to fix the device to the equipment.

[0014] Optionally, the filter plate has a feed hole in its inner cavity and protrusions on its surface. The feed hole is used for material to enter the filtration space formed by the filter plate and filter cloth. There are multiple protrusions, which can evenly distribute the pressure to various parts of the filter plate and avoid the pressure from concentrating on a single point.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. This utility model, through its fixing mechanism, avoids local stress concentration caused by traditional single-point bolt fixing, reducing the risk of filter cloth displacement or detachment due to stretching or vibration. In terms of installation, filter cloth can be installed or replaced without tools, significantly shortening downtime and improving filtration efficiency. Through the locking mechanism, it avoids channel blockage or leakage caused by manual calibration deviation in traditional bolt connections, allowing filter plates to be installed and disassembled quickly and accurately. The design of the locking blocks and slots reduces the number of bolts, nuts, washers, and other parts required for traditional connections, reducing material and processing costs and minimizing manual operation time, with significant advantages, especially in large filter presses.

[0017] 2. This utility model increases the actual filtration area of ​​the filter plate by setting protrusions, allowing more filter media to come into contact with the liquid to be filtered, thereby improving filtration efficiency, increasing the filtration volume per unit time, and increasing the friction between the filter plate and the filter cake, making the filter cake adhere more stably to the filter plate and less likely to slip or fall off during the filtration process, which is beneficial for subsequent unloading operations. The setting of the first and second toothed blocks can embed filter cloth fibers, effectively resisting filter cloth displacement caused by filtrate flow or pressure changes during the filtration process, and avoiding leakage or a decrease in filtration efficiency.

[0028] In this embodiment: the filter plate 1 is circular in shape, so that when the filter plate 1 is subjected to pressure, the force can be evenly distributed throughout the circumference. When subjected to high pressure, it can maintain better structural integrity, reduce the possibility of damage such as cracking and deformation, and extend the service life of the filter plate 1. There are four fixing mechanisms 3 to avoid the filter cloth 2 from being deformed or cracked due to excessive pressure at a single point. The bottom of the toothed plate 303 is fixedly connected to a slider, and the bottom of the slider is provided with a sliding groove.

[0029] Example 2:

[0030] Reference Figure 1-5 A handle 5 is provided on one side of the filter plate 1, and one side of the handle 5 is fixedly connected to the lead screw 301. A first toothed block 6 is fixedly connected to one side of the clamping plate 307. A second toothed block 7 is fixedly connected to the surface of the filter plate 1. A connecting plate 8 is provided on one side of the filter plate 1, and one side of the connecting plate 8 is fixedly connected to the push rod 405. A limiting plate 9 is provided on one side of the clamping block 401, and one side of the limiting plate 9 is fixedly connected to the push rod 405. A groove 10 is opened in the inner cavity of one side of the filter plate 1. A guide hole 11 is opened on one side of the groove 10.

Handles 14 are fixedly connected to both sides of the filter plate 1. A feed hole 15 is opened in the inner cavity of the filter plate 1. A protrusion 16 is provided on the surface of the filter plate 1.

[0031] In this embodiment: the handle 5 allows the operator to drive the entire fixing mechanism 3 to fix the filter cloth 2 simply by rotating the handle 5, improving the convenience of the fixing mechanism 3. There are multiple first toothed blocks 6 and second toothed blocks 7, and after the filter cloth 2 is fixed, the first toothed blocks 6 and second toothed blocks 7 are in a mutually interlocking state, increasing the friction between them and the filter cloth 2, thus improving the stability of the fixing mechanism 3. The connecting plate 8 allows the operator to remove the filter plate 1 by pushing the connecting plate 8 from the outside, improving the convenience of the locking mechanism 4. There are two limiting plates 9, both sides of which are slidably connected to the inner cavity of the filter plate 1, enabling the push rod 405 to... The range of motion is limited to prevent it from detaching from the inner cavity of the filter plate 1. There are two slots 10 located on both sides of the fixing mechanism 3. There are multiple guide holes 11 and water outlet holes 12, which are used to discharge the liquid generated during the filtration process. The rubber pad 13 can increase the sealing between the filter plates 1 and play a buffering role to a certain extent, reducing the impact of collision on the filter plate 1. The handle 14 is used to fix the device and equipment. The feed hole 15 is used for the material to enter the filtration space composed of the filter plate 1 and the filter cloth 2. There are multiple protrusions 16, which can evenly distribute the pressure to various parts of the filter plate 1 and avoid the pressure from concentrating on a single point.

[0032] The implementation principle of this utility model is as follows: When the operator needs to fix the filter cloth 2 to the filter plate 1, the handle 5 is manually rotated. The handle 5 drives the lead screw 301, the lead screw 301 drives the sliding sleeve 302 to move outward, the sliding sleeve 302 drives the toothed plate 303 to move outward, the toothed plate 303 drives the gear 304 to rotate, the gear 304 drives the rotating rod 305, the rotating rod 305 drives the clamping plate 307, and the clamping plate 307 drives the first toothed block 6 to clamp and fix the filter cloth 2. The first toothed block 6 and the second toothed block 7 are interlocked, firmly clamping the filter cloth 2 in the middle, effectively preventing the filter cloth 2 from slipping. To address the issue of easy displacement or detachment, when connecting filter plate 1, align the locking block 401 with the slot 403 and press down to complete the connection. At this time, spring 404 is in a telescopic state. When disassembly is required, manually press the connecting plate 8 to one side. The moving connecting plate 8 drives the push rod 405, which pushes the locking block 401 out of the slot 403. At this time, spring 404 is in a compressed state. After completely disengaging from the slot 403, spring 404 automatically extends and pushes the locking block 401 back to its original position, allowing filter plate 1 to be installed and disassembled quickly and accurately.

[0033] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
