Detailed Implementation
[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] like Figures 1 to 5 The chlorinated paraffin tail gas treatment device of this utility model, as shown, includes a treatment chamber 1, an inlet pipe 2 fixedly connected to the treatment chamber 1, an electric valve 3 installed on the inlet pipe 2, two first fixing brackets 4 fixedly connected to the treatment chamber 1, a drive motor 5 fixedly installed on the first fixing brackets 4, a rotating shaft 6 connected to the drive motor 5, the rotating shaft 6 being rotatably connected to the treatment chamber 1, a cam 7 connected to the rotating shaft 6, and a filter screen 8 slidably connected inside the treatment chamber 1, the filter screen 8 cooperating with the cam 7, and the filter screen 8 being used to filter the tail gas. The dust particles in the air are connected to the treatment chamber 1 by multiple springs 9. A third fixing frame 17 is fixedly connected to the treatment chamber 1. An air extractor 18 is fixedly installed on the third fixing frame 17. A first air supply pipe 19 is connected between the air extractor 18 and the treatment chamber 1. An air suction hood 20 is connected to the first air supply pipe 19. A filter screen is installed on the air suction hood 20. A heat exchanger 22 is fixedly installed on the treatment chamber 1. The heat exchanger 22 is used to recover waste heat. A second air supply pipe 21 is connected between the heat exchanger 22 and the air extractor 18.
[0020] A water tank 10 is fixedly connected to the treatment chamber 1. A cooler 11 is installed inside the water tank 10. Two second fixed brackets 12 are fixedly connected to the treatment chamber 1. A water pump 13 is fixedly installed on the second fixed brackets 12. A water supply pipe 14 is connected between the water pump 13 and the water tank 10. A cooling pipe 15 is connected between the two water pumps 13 and the cooling pipe 15 is connected to the treatment chamber 1.
[0021] A reinforcing ring 16 is connected between the processing box 1 and the cooling pipe 15.
[0022] Two fixed rods 23 are fixedly connected to the processing box 1. Two fourth fixed frames 24 are fixedly connected to the processing box 1. An electric push rod 25 is fixedly installed on the fourth fixed frame 24. A connecting rod 26 is connected to the extension rod of the electric push rod 25. A sealing plate 27 is connected to the connecting rod 26. The sealing plate 27 is slidably connected to the fixed rod 23.
[0023] The working principle of this utility model is as follows: After the electric valve opens the air inlet pipe, the exhaust gas enters the processing chamber through the air inlet pipe. When the exhaust gas passes through the filter screen, the filter screen filters the dust particles in the exhaust gas, thereby separating the dust particles. The exhaust gas comes into contact with the cooling pipe after passing through the filter screen. The water pump draws the aqueous solution, which enters the cooling pipe through the water supply pipe. The aqueous solution in the cooling pipe exchanges heat with the exhaust gas. Another water pump draws the aqueous solution in the cooling pipe back to the water tank. The cooler cools the aqueous solution, thereby forming a circulating heat exchange effect. After the exhaust gas exchanges heat, the exhaust gas is drawn by the exhaust gas pump. When the exhaust gas passes through the suction hood, it is filtered a second time by the filter screen on the suction hood, thereby improving the cleanliness of the exhaust gas. The exhaust gas enters the heat exchanger through the first and second air supply pipes. The heat exchanger recovers and utilizes the remaining heat of the exhaust gas.
[0024] After the exhaust gas is treated, the electric push rod drives the connecting rod and the sealing plate to rise, causing the sealing plate to open the discharge channel of the treatment box. Then, the drive motor drives the rotating shaft and cam to rotate. After the cam rotates to contact the filter screen, it drives the filter screen to fall. The spring deforms, and after the cam rotates and disengages from the filter screen, the spring returns to its original position, thereby driving the filter screen to rise. Through the continuous rising and falling of the filter screen, the dust particles on the filter screen are shaken out, thus achieving the effect of automatically cleaning the dust particles, which then slide out along the discharge channel of the treatment box.
[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
