[0002] Potassium permanganate is a strong oxidant, which is black purple, long prismatic crystal or particle, with blue metal luster, odorless, and can be used for disinfection, sterilization, bleaching, dyeing, oxidation and other purposes. In the laboratory, potassium permanganate is often used for organic synthesis, titration analysis, etc.
[0003] Potassium permanganate involves multiple chemical reaction steps in the production process, such as oxidation, reduction, etc. These reactions may produce smoke dust, and the potassium permanganate waste gas is mainly composed of sulfur dioxide, nitrogen oxides, sulfuric acid mist and particulate matter, etc. If the smoke dust is not treated and directly discharged, it will have a serious impact on the production environment, employees and the health of surrounding residents. The smoke dust is generally removed by a scrubber to remove particulate matter and sulfuric acid mist in the waste gas. It absorbs the particulate matter and sulfuric acid mist in the waste gas through circulating liquid, and then converts them into harmless substances through chemical reaction.
[0004] In the prior art, the smoke dust collected by potassium permanganate production is purified, but before the smoke dust is treated, it lacks cooling function for the smoke dust. The temperature of the smoke dust in the production process may be very high, and the lack of cooling function will not inhibit its chemical reaction activity, thus increasing the possibility of reaction with other substances in the air. Therefore, a smoke dust collecting device in potassium permanganate production process is proposed to solve the above problems. UTILITY MODEL CONTENT

The water pump 6 transmits the coolant to the inside of the isolation box 5 through the liquid inlet pipe 7. The side wall of the isolation box 5 is fixedly connected to a motor 8, and the output end of the motor 8 is fixedly connected to a rotating shaft 9. The outer wall of the rotating shaft 9 is fixedly connected to a stirring blade 10. The stirring blade 10 can stir the coolant so that the coolant flows inside the isolation box 5, accelerating the contact between the coolant and the wall of the cooling channel 4. The inner wall of the isolation box 5 is fixedly connected to a drain pipe 11, which can discharge the coolant out of the isolation box 5. The drain pipe 11 is sealed by an external sealing cover. The interior of the isolation box 5 is provided with a knocking component, and the surface of the collecting box 1 is provided with a refrigeration component.
[0033] Reference Figure 3-Figure 5, one end of the liquid inlet pipe 7 away from the water pump 6 passes through the interior of the isolation box 5, the outer wall of the bottom end of the cooling channel 4 is fixedly connected to the inner wall of the isolation box 5, the cooling channel 4 is fixedly connected to the pipe mouth of the smoke inlet pipe 2, and the knocking assembly includes an auxiliary shaft 12, the end of the auxiliary shaft 12 is fixedly connected to the end of the telescopic rod 19, the outer wall of the auxiliary shaft 12 is fixedly connected with a knocking rod 13, and the outer wall of the cooling channel 4 is fixedly connected with a bump 14. The knocking rod 13 can knock the two groups of bumps 14 when the auxiliary shaft 12 rotates one circle. The two groups of bumps 14 are respectively located On the outer wall of the cooling channel 4, the refrigeration component includes an exhaust pipe 15, which runs through the interior of the isolation box 5. A one-way valve 16 is provided on the surface of the exhaust pipe 15. The one-way valve 16 controls the flow direction of the exhaust pipe 15 so that the exhaust pipe 15 can only discharge gas, and the outside air cannot enter the isolation box 5 through the exhaust pipe 15. The side wall of the collection box 1 is fixedly connected to a refrigerator 17, which is fixedly connected to the isolation box 5 through a pipeline. The refrigerator 17 transmits cold air to the interior of the isolation box 5 through the pipeline to ensure that the coolant is always cold.
[0034] Reference Figure 5 An embedding groove 18 is opened at the center of the rotating shaft 9, and a telescopic rod 19 is fixedly connected to the inner wall of the embedding groove 18, and a spring 20 is fixedly connected to the outer wall of the telescopic rod 19. One end of the spring 20 is fixedly connected to the inner wall of the embedding groove 18, and the other end of the spring 20 is fixedly connected to the end of the auxiliary shaft 12. The elasticity of the spring 20 and the telescopic rod 19 can reduce the vibration force generated by the knocking rod 13 contacting the bump 14 and affecting the rotating shaft 9.
[0035] Working principle: Connect the water pump 6 to the external pipeline to introduce the coolant into the isolation box 5. At the same time, the refrigerator 17 is turned on to keep the coolant always cold. The excess cold air is discharged from the isolation box 5 through the exhaust pipe 15 to keep the pressure inside the isolation box 5 stable. The coolant conducts heat and cools the smoke through the metal cooling channel 4. The smoke is cooled to a suitable temperature in preparation for subsequent processing. At this time, the motor 8 is turned on again. The motor 8 controls the rotation of the shaft 9 to make the stirring blade 10 stir in the isolation box 5, thereby expanding the contact area and contact degree between the coolant and the pipe wall of the cooling channel 4 to ensure the cooling effect on the smoke. At the same time, the auxiliary shaft 12 will rotate with the shaft 9, and the knocking rod 13 will squeeze and knock the bump 14. After the bump 14 is subjected to force, the vibration force will be transmitted to the cooling channel 4, so that when it transports the smoke, the particles contained in the smoke will not stay on the inner wall of the pipe, thereby ensuring the collection and processing efficiency of the smoke. Finally, the smoke is transmitted through the cooling channel 4 to the bottom area of the collection box 1 for spraying to remove dust particles and some harmful gases in the smoke.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
