Pressing device for rapidly replacing filter cloth of filter

Abstract

The utility model discloses a pressing device for quickly replacing filter cloth of a filter. The pressing device mainly comprises a push-pull type quick clamp, the filter cloth, polytetrafluoroethylene packing and a pressing ring. The device replaces an original bolt to fix the filter cloth, so that the operation time is shortened, the working efficiency is improved, the activated carbon cannot leak out of a bolt hole, and the output rate of equipment is increased.

Description

Technical Field

[0001] The invention relates to the field of equipment design and manufacturing. By replacing a pressing device of a filter cloth, the filter cloth can be quickly replaced, the filter cloth replacement time can be reduced, and the equipment output rate can be improved. Background Art

[0002] The filter equipment currently used has an unreasonable design of the filter cloth pressing device, and it is necessary to punch holes in the filter cloth during the process of fastening the filter cloth with bolts. During the activated carbon filter press, the powdered activated carbon will seep out from the bolt holes, causing the activated carbon separation to fail. After the filter cloth leaks, personnel enter the filter cavity to remove and reinstall the filter cloth, which is time-consuming and laborious. Therefore, it is very necessary to make a pressing device for quickly replacing the filter cloth. Summary of the invention

[0003] The purpose of the utility model is to solve the problem of cumbersome bolt disassembly and assembly during filter cloth replacement. The filter cloth is fixed by a pressure ring instead of the traditional bolt fixation. The filter cloth can be quickly disassembled by switching the push-pull quick clamp, which greatly reduces the filter cloth replacement time. The filter cloth fixed by bolts takes about 4 hours to replace, while the filter cloth fixed by a pressure ring only takes 30 minutes to replace, which reduces the confined space operation time, improves the filter cloth replacement quality, and increases the equipment output rate.

[0004] The utility model is implemented as follows: a clamping device for quickly replacing filter cloth, mainly comprising a push-pull quick clamp, filter cloth, PTFE packing, and a pressure ring. After the push-pull quick clamp is welded to the mounting base, the lifting of the lower pressure ring is controlled by lifting the push-pull quick clamp up and down, and the PTFE packing is under the pressure ring, and the filter cloth is pressed under the PTFE packing. When the filter cloth needs to be replaced, the push-pull quick clamp is released, thereby driving the pressure ring under the push-pull quick clamp to rise, and after taking out the packing, the old filter cloth is removed, and the new filter cloth is re-laid. After pressing down the packing, the push-pull quick clamp is pressed up, thereby pressing the packing and replacing the filter cloth is completed.

[0005] The beneficial effects of the utility model are that the device has a simple structure, is easy to transform, can quickly replace the filter cloth, and greatly reduces the filter cloth replacement time. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Attached Figure 1 The utility model shows a structural schematic diagram of a clamping device for quickly replacing filter cloth.

[0008] Attached Figure 1The structure diagram of the utility model is shown. Figure 1 The utility model is further described.

[0009] A clamping device for quickly replacing filter cloth, mainly comprising a push-pull quick clamp (1), filter cloth (2), polytetrafluoroethylene packing (3), and a pressure ring (4). The device is characterized in that the push-pull quick clamp (1) is connected to the pressure ring (4), the pressure ring (4) is connected to the polytetrafluoroethylene packing (3), and the polytetrafluoroethylene packing (3) is connected to the filter cloth (2). The push-pull quick clamp is welded to an equipment installation base and is used to fix the push-pull quick clamp (1).

[0010] Working process: After the push-pull quick clamp (1) is welded to the mounting base, the push-pull quick clamp (1) is lifted up and down to control the lifting of the lower pressure ring (4). Under the pressure ring (4) is a PTFE packing (3). The PTFE packing (3) is used to press the filter cloth (2) and seal the inside of the equipment to prevent the activated carbon from falling from the inner wall of the equipment. The PTFE packing (3) presses the filter cloth (2). When the filter cloth (2) needs to be replaced, the push-pull quick clamp (1) is released, thereby driving the pressure ring (4) under the push-pull quick clamp (1) to rise. After the PTFE packing (3) is taken out, the filter cloth (2) is removed and a new filter cloth (2) is re-installed. After the PTFE packing (3) is pressed down, the push-pull quick clamp (1) is pressed down to press the PTFE packing (3) and replace the filter cloth (2). A total of 8 push-pull quick clamps are installed around the inside of the filter equipment to fix the filter cloth.

[0011] The device has a simple structure and is easy to operate, and can quickly replace the filter cloth, thereby greatly shortening the filter cloth replacement time.

Claims

1. A clamping device for quickly replacing filter cloth, mainly composed of a push-pull type quick clamp (1), a filter cloth (2), a polytetrafluoroethylene packing (3), and a pressure ring (4), characterized in that: The push-pull quick clamp (1) is connected to a pressure ring (4), the pressure ring (4) is connected to a polytetrafluoroethylene packing (3), and the polytetrafluoroethylene packing (3) is connected to a filter cloth (2).
