[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 - Figure 4 , the present invention provides a technical solution:

[0025] Refer to Figure 1 - Figure 4 As shown in, an exhaust gas collection and filtration mechanism for a sintering furnace includes a sintering furnace body 1. A filtration component 2 is arranged on one side of the sintering furnace body 1. The filtration component 2 includes a first air pipe 201. One end of the first air pipe 201 is fixedly installed with a first activated carbon filter box 205. A first solenoid valve 202 is fixedly installed on the first air pipe 201. The outer wall of the first solenoid valve 202 is fixedly installed with a second air pipe 203. A second solenoid valve 204 is fixedly installed on the second air pipe 203. One end of the second air pipe 203 away from the first air pipe 201 is fixedly installed with a second activated carbon filter box 206. The first activated carbon filter box 205 is installed on the top of the second activated carbon filter box 206.

[0026] When the second solenoid valve 204 is in the closed state, control the first solenoid valve 202 to open. The exhaust gas after passing through the water tank 6 enters the first activated carbon filter box 205 through the first air pipe 201 and can be discharged into the air through the exhaust pipe 13 after filtration. When the activated carbon particles inside the first activated carbon filter box 205 are saturated, the first solenoid valve 202 can be closed and the second solenoid valve 204 can be opened. The gas can enter the inside of the second activated carbon filter box 206 through the second air pipe 203 for filtration, without interrupting the filtration work and waiting until the activated carbon particles inside the first activated carbon filter box 205 are replaced before continuing to filter the gas. This ensures the continuity of the work and greatly improves the efficiency of the filtration work.

[0027] Refer to Figure 1, a connecting pipe 3 is fixedly installed on the sintering furnace body 1, one end of the connecting pipe 3 away from the sintering furnace body 1 is fixedly installed with a water ring pump 4, two pipelines 5 are installed on the water ring pump 4, the other end of the pipeline 5 is fixedly installed with a water tank 6, and one end of the first air pipe 201 away from the first activated carbon filter box 205 penetrates into the interior of the water tank 6.

[0028] The sintering furnace body 1 and the water ring pump 4 enable the gas generated in the sintering furnace body 1 to smoothly enter the water ring pump 4 for subsequent treatment. The exhaust gas enters the water tank 6 to utilize the cooling water in the water tank 6 to treat or cool the exhaust gas.

[0029] Refer to Figure 2 - 3 , on one side of the first activated carbon filter box 205 and the second activated carbon filter box 206, an exhaust pipe 13 is fixedly installed, and an exhaust fan 14 is fixedly installed on the exhaust pipe 13.

[0030] The exhaust fan 14 discharges the gas filtered by the first activated carbon filter box 205 and the second activated carbon filter box 206 to the outside through the exhaust pipe 13. The operation of the exhaust fan 14 can accelerate the flow rate of the gas in the first activated carbon filter box 205 and the second activated carbon filter box 206, enabling the exhaust gas to pass through the filter box more quickly, reducing the treatment time, and improving the treatment efficiency.

[0031] Refer to Figure 2 - 3 , on one side of the first activated carbon filter box 205 and the second activated carbon filter box 206, hinges are installed, and the first activated carbon filter box 205 and the second activated carbon filter box 206 are both hinged with a box door 10 through the hinges.

[0032] The hinges enable the box door 10 to be easily opened and closed, facilitating the internal maintenance of the first activated carbon filter box 205 and the second activated carbon filter box 206 and the replacement of the activated carbon. The hinged design also makes the opening process of the box door 10 smoother and more stable, enhancing the convenience of user operation.

[0033] Refer to Figure 1 , on one side of the first activated carbon filter box 205 and the second activated carbon filter box 206, a handle 7 is provided, two insertion rods 8 are fixedly installed on one side of the handle 7, a return spring 9 is provided on the outer wall of each insertion rod 8, and one end of the insertion rod 8 away from the handle 7 extends into the interior of the box door 10.

[0034] When replacing the activated carbon particles in either the first activated carbon filter box 205 or the second activated carbon filter box 206, the user holds the handle 7 and pulls it away from the first activated carbon filter box 205 or the second activated carbon filter box 206. The return spring 9 expands under the pulling force, and the insertion rod 8 disengages from the box door 10. At this time, the box door 10 can be opened to take out the activated carbon particles, and then the new activated carbon can be replaced into the first activated carbon filter box 205 or the second activated carbon filter box 206 through the feeding pipe 11.

[0035] Refer to Figure 2 - 3 , an emptying pipe 11 is installed on the outer wall of the box door 10, and a sealing cover 12 is threadedly connected to the top of the emptying pipe 11.

[0036] The design of the emptying pipe 11 makes it more convenient to add or replace the activated carbon in the first activated carbon filter box 205 or the second activated carbon filter box 206. The user can directly pour the activated carbon into the first activated carbon filter box 205 or the second activated carbon filter box 206 through the emptying pipe 11 by opening the sealing cover 12, without opening the entire box door 10, thus simplifying the operation process.

[0037] Refer to Figure 2 - 3 , both the emptying pipe 11 and the sealing cover 12 are made of polyethylene.

[0038] Polyethylene has good wear resistance. During the frequent opening and closing and the passing of materials, the emptying pipe 11 and the sealing cover 12 can maintain their shapes and functions, are not easily worn, and reduce the frequency of maintenance and replacement.

[0039] Refer to Figure 2 - 3 , the emptying pipe 11 is arranged in an L shape.

[0040] The emptying pipe 11 is arranged in an L shape with the feeding port facing upward. When adding activated carbon, it can effectively prevent the activated carbon from leaking or splashing out from the feeding port during the pouring process, which helps to ensure that the activated carbon can accurately and completely enter the emptying pipe 11 and avoid dropping waste or cleaning trouble.

[0041] Working principle: The second solenoid valve 204 is in the closed state, and the first solenoid valve 202 is controlled to open. The waste gas after passing through the water tank 6 enters the first activated carbon filter box 205 through the first air pipe 201 and can be discharged into the air through the exhaust pipe 13 after filtration. When the activated carbon particles inside the first activated carbon filter box 205 are saturated, the first solenoid valve 202 can be closed and the second solenoid valve 204 can be opened. The gas can enter the inside of the second activated carbon filter box 206 through the second air pipe 203 for filtration, without the need to interrupt the filtration work and wait until the activated carbon particles inside the first activated carbon filter box 205 are replaced before continuing to filter the gas, which ensures the continuity of the work and greatly improves the efficiency of the filtration work.

[0042] When replacing the activated carbon particles in the first activated carbon filter box 205 or the second activated carbon filter box 206, the user holds the grip 7 and pulls it away from the first activated carbon filter box 205 or the second activated carbon filter box 206. The return spring 9 is stretched under the pulling force, and the insertion rod 8 disengages from the box door 10. At this time, the box door 10 can be opened to take out the activated carbon particles, and then new activated carbon can be replaced into the first activated carbon filter box 205 or the second activated carbon filter box 206 through the emptying pipe 11.
