[0036] As Figures 1 to 3As shown in the figure, an embodiment of the present utility model provides an industrial waste gas circulation treatment device, including: a purification box 1; a filtration box 4, installed on the inner wall of the purification box 1 to treat waste gas; an intake pipe 2, connected and fixedly connected to the surface of the filtration box 4 to convey waste gas; an exhaust pipe 3, connected and fixedly connected to the surface of the filtration box 4 to convey purified gas; a filter plate 5, installed on the inner wall of the filtration box 4 to purify waste gas; a replacement device 6, arranged on the surface of the purification box 1 to facilitate the staff to replace the filter plate 5; a protection device 7, arranged on the surface of the purification box 1 to protect the opening on the surface of the purification box 1.

[0037] As Figures 4 to 6 shown, the replacement device 6 includes a fixed frame 601, the fixed frame 601 is detachably installed with the purification box 1, a cloth cover 605 is fixedly connected to the surface of the fixed frame 601, a rectangular plate 602 is fixedly connected to the surface of the cloth cover 605, a handle 606 is fixedly connected to the surface of the rectangular plate 602, and a thorn rod 607 is fixedly connected to the surface of the rectangular plate 602. When industrial waste gas needs to be treated, the industrial waste gas in the factory enters the interior of the purification box 1 through the intake pipe 2. The filter plate 5 in the filtration box 4 will adsorb harmful substances in the waste gas, and then be discharged through the exhaust pipe 3. The filter plate 5 that has been used for a long time needs to be replaced. The staff covers the fixed frame 601 on the surface of the purification box 1, and then holds the handle 606 to push the rectangular plate 602 to move. The conical thorn rod on the rectangular plate 602 pierces into the filter plate 5, and the filter plate 5 is pulled out from the filtration box 4 and the purification box 1. The cloth cover 605 will cover the surface of the filter plate 5. A round rod 603 is fixedly connected to the surface of the fixed frame 601. The round rod 603 is slidably connected to the rectangular plate 602. A limit ring 604 is sleeved on the arc surface of the round rod 603. The limit ring 604 is fixedly connected to the cloth cover 605. The rectangular plate 602 will move along the round rod 603, and the limit ring 604 will slide on the round rod 603, so as to support the cloth cover 605 and prevent it from being pierced by the thorn rod 607. A guiding frame 610 is fixedly connected to the surface of the purification box 1. The staff covers the fixed frame 601 on the surface of the purification box 1 along the guiding frame 610. A positioning hole 608 is opened on the surface of the fixed frame 601. A lead screw 609 is threadedly connected to the surface of the guiding frame 610. The size of the lead screw 609 is adapted to the size of the positioning hole 608. The lead screw 609 is rotated and inserted into the positioning hole 608 on the surface of the fixed frame 601 to limit the fixed frame 601.

[0038] In the embodiment of the present utility model, when it is necessary to treat industrial waste gas, the industrial waste gas in the factory enters the interior of the purification box 1 through the intake pipe 2. The filter plate 5 in the filter box 4 will adsorb harmful substances in the waste gas, and then is discharged through the exhaust pipe 3. The filter plate 5 that has been used for a long time needs to be replaced. The staff covers the fixing frame 601 on the surface of the purification box 1 along the guiding frame 610, rotates the lead screw 609 and inserts it into the positioning hole 608 on the surface of the fixing frame 601 to limit the fixing frame 601. Then, hold the handle 606 and push the rectangular plate 602 to move. The conical thorn rod on the rectangular plate 602 pierces into the filter plate 5. The rectangular plate 602 will move along the round rod 603, and the limiting ring 604 will slide on the round rod 603, so that the supporting cloth cover 605 will not be pierced by the thorn rod 607, and the filter plate 5 is pulled out from the filter box 4 and the purification box 1, and the cloth cover 605 will be sleeved on the surface of the filter plate 5.

[0039] As Figures 7 to 8 shown, the protection device 7 includes a plug board 71. The plug board 71 is slidably connected to the purification box 1. Two fixing holes 72 are formed on the surface of the plug board 71. A fixing pin 76 is slidably connected to the surface of the purification box 1. The sizes of the two fixing holes 72 are adapted to the size of the fixing pin 76. One end of the fixing pin 76 is fixedly connected to a fixing plate 74. When it is necessary to replace the filter plate 5, the plug board 71 is moved so as not to block the filter plate 5, and then the fixing pin 76 is inserted into the fixing hole 72 to fix the plug board 71. After the replacement of the filter plate 5 is completed, the staff pulls out the fixing pin 76, and the plug board 71 automatically drops. Then, the fixing pin 76 is inserted into the fixing hole 72 for fixing. The arc surface of the fixing pin 76 is sleeved with a spring 77. One end of the spring 77 is fixedly connected to the fixing plate 74, and the other end of the spring 77 is fixedly connected to the purification box 1. The spring 77 is in a stretched state. When the spring 77 contracts, it will limit the fixing pin 76, so that the fixing pin 76 is stably inserted into the fixing hole 72. A second pull ring 75 is fixedly connected to the surface of the fixing plate 74, and a first pull ring 73 is fixedly connected to the surface of the plug board 71. The plug board 71 is moved by pulling the pull ring, and the fixing pin 76 and the fixing plate 74 are moved by pulling the second pull ring 75.

[0040] In the embodiment of the present utility model, when it is necessary to replace the filter plate 5, the plug board 71 is moved by pulling the pull ring to move the plug board 71 so as not to block the filter plate 5. Then, the fixing pin 76 is inserted into the fixing hole 72 to fix the plug board 71. After the replacement of the filter plate 5 is completed, the staff pulls out the fixing pin 76, and the fixing pin 76 and the fixing plate 74 are moved by pulling the second pull ring 75. At this time, the spring 77 is in a stretched state. When the spring 77 contracts, it will limit the fixing pin 76, so that the fixing pin 76 is stably inserted into the fixing hole 72, and the plug board 71 automatically drops. Then, the fixing pin 76 is inserted into the fixing hole 72 for fixing.

[0041] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
