[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device. Background Art

[0002] In order to remove toxic and harmful substances and smoke from industrial waste gas, make it meet emission standards after treatment, reduce air pollution, and achieve the goal of improving the ecological environment and climate, waste gas treatment equipment is needed. There are many types of waste gas treatment equipment, and activated carbon adsorption box is one of them. Its working principle is to pass air through the activated carbon adsorption layer so that harmful gases and odors in the air are adsorbed onto the surface of activated carbon, thereby achieving the purpose of purifying the air.

[0003] At present, the existing activated carbon adsorption box supports the activated carbon through multiple drawers when in use. After a period of use, the adsorption capacity of the activated carbon will be saturated, so the activated carbon in the drawer needs to be replaced. Since the multiple drawers are connected to the box body through multiple groups of bolts, the operator needs to use tools to remove and install the multiple bolts one by one during the replacement of the activated carbon, which reduces the replacement efficiency of the activated carbon to a certain extent and increases the labor intensity of the operator. For this reason, we propose an exhaust gas treatment device to solve the above problems. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 , an exhaust gas treatment device, including an activated carbon adsorption box 1, drawers 2 are inserted equidistantly inside the activated carbon adsorption box 1, and handles 3 are connected to the front of the drawers 2, a fixing bar 4 is distributed on the top of the front of the activated carbon adsorption box 1, and a slot 5 is opened inside the fixing bar 4, and an opposing screw 6 is connected to the inside of the slot 5 through a bearing, and a bevel gear set 7 is sleeved at the center of the opposing screw 6, and two groups of external threads with opposite rotation directions are opened inside the opposing screw 6, which are not shown in the figure, so that when the opposing screw 6 rotates, the two groups of threaded sleeves 10 can rotate in opposite directions, and the bevel gear set 7 is composed of two groups of bevel gears, and the two groups of bevel gears are fixedly sleeved on the outer sides of the rotating rod 8 and the opposing screw 6 respectively, so that when the rotating rod 8 rotates, the opposing screw 6 can be driven During the reversal of rotation, the rotating rod 8 is connected to the inner wall of the fixed strip 4 through the bearing, thereby effectively ensuring the stability of the rotating rod 8 during rotation. A rotating rod 8 is inserted into the front of the bevel gear set 7, and the rotating rod 8 extends to the outside of the fixed strip 4. Two groups of threaded sleeves 10 are sleeved on the outer side of the opposing screw rod 6, and the bottom ends of the two groups of threaded sleeves 10 are respectively connected by a connecting rod and a limiting strip 11. A moving groove matched with the connecting rod is opened inside the fixed strip 4. Through the mutual cooperation of the moving rod and the moving groove, the normal sliding of the threaded sleeve 10 in the groove hole 5 can be effectively guaranteed. A clamping strip 12 is connected to the side of the limiting strip 11, and a positioning groove is opened on the side of the drawer 2 at a position corresponding to the clamping strip 12. By opening the positioning groove, each group of drawers 2 can be quickly positioned.

[0024] Further, see Figure 3 and Figure 4 It can be seen that the outer side of the card strip 12 is glued with an anti-slip sleeve 13, and the outer wall of the anti-slip sleeve 13 and the inner wall of the positioning groove are tightly fitted. Through the gluing of the anti-slip sleeve 13, the tightness of the card strip 12 in the positioning groove inside the drawer 2 can be effectively ensured.

[0025] Further, see Figure 2 and Figure 3 It can be known that a sealing strip 15 is connected to the inner side of the drawer 2, and a sealing groove is opened on the front side of the activated carbon adsorption box 1 at a position corresponding to the sealing strip 15, and the sealing groove and the sealing strip 15 are arranged in a U-shaped structure. The sealing strip 15 and the sealing groove arranged in the U-shaped structure can effectively ensure the sealing of the drawer 2 when it is engaged in the activated carbon adsorption box 1.

[0026] Further, see Figure 1 and Figure 2 It can be seen that the lower side of the fixing strip 4 is symmetrically connected with a mounting plate 16, and the interior of the mounting plate 16 is connected to the activated carbon adsorption box 1 by bolts. Through the cooperation between the mounting plate 16 and the bolts, the fixing strip 4 can be disassembled and assembled, so that the staff can perform inspection and maintenance operations.

[0027] Further, see Figure 1 and Figure 2 It can be seen that the bottom end of the mounting plate 16 is laterally connected to a guide rod 17, and the bottom end of the limit bar 11 is provided with a hole adapted to the guide rod 17. Through the mutual cooperation between the hole and the guide rod 17, the stability of the limit bar 11 during movement can be effectively guaranteed.

[0028] Further, see Figure 3 It can be seen that the back of the drawer 2 is symmetrically wrapped with an anti-collision strip 14, and the anti-collision strip 14 is set to a cylindrical structure. The rubber anti-collision strip 14 can prevent the back of the card strip 12 from directly colliding with the activated carbon adsorption box 1 during the insertion process, so as to protect the back corners of the drawer 2. Since the anti-collision strip 14 is set to a cylindrical shape, the protection effect on the back of the drawer 2 can be improved.

[0029] Further, see Figure 4 and Figure 5 It can be seen that the front of the rotating rod 8 is connected to a rotating piece 9, and the rotating pieces 9 are distributed on the outer surface of the rotating rod 8 in a ring array structure. By setting up multiple groups of rotating pieces 9, it is convenient for the staff to rotate the rotating rod 8, thereby effectively improving the convenience of the device during use.

[0030] Working principle: When the utility model is used, the staff can first install the activated carbon adsorption box 1 at a suitable position, and then connect the corresponding pipeline and the activated carbon adsorption box 1. The activated carbon supported by the drawer 2 can be used to treat the exhaust gas. After a period of treatment, the staff only needs to turn the rotating piece 9 to drive the rotation of the rotating rod 8. During the rotation of the rotating rod 8, the setting of the bevel gear set 7 can make the opposing screw rod 6 rotate in reverse direction, so that the two sets of threaded sleeves 10 set on the outer side of the opposing screw rod 6 move in opposite directions inside the slot 5. Through the setting of the connecting rod, the two sets of limiting The positioning strips 11 are forced to move away from each other, so that the card strips 12 connected to the side of the limiting strips 11 can be pulled out from the positioning grooves inside each group of drawers 2 to release the limit on the drawers 2, and then the staff can pull the handles 3 by hand to pull the drawers 2 out of the activated carbon adsorption box 1. At this time, the staff can replace the activated carbon inside each group of drawers 2. After the replacement is completed, each group of drawers 2 can be inserted into the activated carbon adsorption box 1 again, and then by reverse rotation, the card strips 12 connected to the side of the limiting strips 11 can be engaged with the inside of the drawers 2 to achieve re-positioning of the drawers 2. The above is the entire working principle of the utility model.

As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
