DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figures 1 to 6 As shown, the utility model provides a gas processing device for industrial environmental protection, comprising a gas purification box (not shown in the figure), a vacuum pump (not shown in the figure) and a gas collecting hood 1 which are connected in sequence.

[0021] A shell (not shown in the figure) is arranged outside the air collecting hood 1, a cover plate 2 is arranged on the front of the air collecting hood 1, and an unwinding roller 4 and a winding roller 5 are arranged on both sides of the back of the air collecting hood 1. Pulleys 12 are installed on the roller shafts of the winding roller 5 and the unwinding roller 4, and the two pulleys 12 are connected by a synchronous belt 13, and one of the pulleys 12 is driven to rotate by a knob 14.

[0022] Guide rollers 3 are elastically mounted on both sides of the cover plate 2. Specifically:

[0023] The upper and lower sections on both sides of the cover plate 2 are respectively provided with guide holes 10, and a connecting rod 9 is slidably installed at the guide hole 10 through a return spring 11. The outer end of the connecting rod 9 is connected to a sleeve 8 of the roller shaft of the guide roller 3 mounted on the corresponding side.

[0024] The two ends of the filter mesh cloth 6 are respectively wound on the unwinding roller 4 and the winding roller 5, and the middle part of the filter mesh cloth 6 passes around the guide rollers 3 on both sides and the surface of the middle cover plate 2. The surface of the cover plate 2 is also connected to a pressing frame 7 for pressing the filter mesh cloth 6 tightly against the surface of the cover plate 2.

[0025] The cover plate 2 and the pressing frame 7 are locked by a locking member. Specifically:

[0026] The locking member includes a guide groove 15 provided at the upper and lower ends of the cover plate 2, a guide rod 16 capable of sliding along the guide groove 15 is installed on the pressure frame 7 through a compression spring 21, a limit groove 17 is vertically provided on the side wall of the guide rod 16, a driving rod 20 is rotatably provided on the cover plate 2 perpendicular to the guide rod 16, a lever 19 is provided on the driving rod 20, a limit block 18 for sliding up and down in the limit groove 17 is provided at the front end of the lever 19, the driving rod 20 is driven to rotate by a rotating rod 22, a positioning block 25 is provided on the air collecting hood 1, and the positioning block 25 and the rotating rod 22 are locked by a pin shaft 26.

[0027] In order to improve the compression degree of the filter cloth 6 , the surrounding surfaces of the cover plate 2 are provided with clamping grooves 23 , and the inner surface of the pressing frame 7 is provided with clamping blocks 24 corresponding to the clamping grooves 23 .

[0028] The working principle of replacing the filter cloth 6 of the utility model device is:

[0029] When it is necessary to replace the filter mesh 6 at the air inlet cover plate 2, first pull out the pin 26 at the positioning block 25, and rotate the rotating rod 22 to rotate the driving rod 20. The limit block 18 on the lever 19 connected to the driving rod 20 limits the guide rod 16 where the limit groove 17 is located to move toward the side away from the cover plate 2, so that the pressing frame 7 moves toward the side away from the cover plate 2. At this time, the filter mesh 6 is no longer pressed between the cover plate 2 and the pressing frame 7.

[0030] After that, the knob 14 is rotated to make the two pulleys 12 rotate synchronously, the unwinding roller 4 unwinds the filter mesh 6, and the rewinding roller 5 rewinds the filter mesh 6. As the diameter of the filter mesh 6 at the unwinding roller 4 and the rewinding roller 5 changes, the unwinding speed and the unwinding speed may be inconsistent, but due to the elastic support of the guide roller 3 on both sides of the filter mesh 6, the filter mesh 6 can be kept in a relatively tensioned state during the replacement process. When the filter mesh 6 at the cover plate 2 is completely replaced, the pressure frame 7 can be adjusted to press against the surface of the cover plate 2, so that the filter mesh 6 is in a relatively stretched gas filtering state, thereby ensuring the filtering effect.

[0031] The utility model device does not need to disassemble and replace the filter mesh part during the process of replacing the filter mesh cloth 6. The method of rolling and replacing the filter mesh cloth 6 by combining unwinding and rewinding is adopted, and the elastically arranged guide roller 3 overcomes the inconsistent rewinding and unwinding speed caused by the change of the reel diameter at the end of the filter mesh cloth 6, so that the filter mesh cloth 6 is always kept in a tensioned state, and the filter mesh cloth 6 is pressed against the surface of the cover plate 2 by the pressing frame 7, so that the filter mesh cloth 6 is in a relatively stretched gas filtering state to ensure the filtering effect, reduce the burden of disassembling and replacing the filter mesh, and improve the efficiency of gas treatment.

[0032] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
