[0001] The utility model relates to the technical field of catalytic combustion devices, and particularly relates to a catalytic combustion treatment device provided with a recovery component. Background Technique

[0002] A catalytic combustion treatment device is a device that can help convert harmful substances in waste gas into harmless substances. Through the action of a catalyst, it promotes chemical reactions of pollutants in the waste gas at high temperatures, thereby reducing the emission of harmful gases. This device is widely used in industrial production and environmental protection fields, can effectively purify waste gas, reduce atmospheric pollutant emissions, and plays a positive role in improving environmental quality.

[0003] A catalytic combustion device with the publication number of CN218583182U, through the provided double-stage heat recovery component, enables the organic waste gas to pass through the air ducts arranged by each partition plate and pass through the first thin plate heat exchanger and the second thin plate heat exchanger respectively to achieve the effect of double catalytic combustion, so that this device solves the problem of low single-stage heat recovery conversion rate of traditional catalytic combustion devices.

[0004] The waste gas of the above patent enters the box body through a flame arrester. However, there are many impurities in the waste gas, and the flame arrester is not convenient for blocking the impurities in the waste gas, which affects the catalytic combustion effect of the waste gas. For this reason, we propose a catalytic combustion treatment device provided with a recovery component. Content of the Utility Model

[0005] The purpose of the utility model is to provide a catalytic combustion treatment device provided with a recovery component to solve the problem that the impurities in the waste gas affect the catalytic combustion effect of the waste gas proposed in the above background technique.

An exhaust gas inlet pipe is arranged on the outer side wall of the airtight box in a communicating way. A fixed box is installed at the top of the airtight box. A lifting toothed plate is vertically slidably connected in the fixed box. A cleaning plate is arranged at the bottom of the lifting toothed plate. The side wall of the cleaning plate is attached to the side wall of the filter screen plate. A blanking channel is installed at the bottom of the airtight box in a communicating way. A sealing baffle is horizontally slidably connected in the blanking channel.

[0008] Furthermore: A reduction motor is connected to the front outer wall of the fixed box. A rotating shaft is installed at the output end of the reduction motor. The bottom end of the rotating shaft is rotatably connected to the rear inner wall of the fixed box through a bearing. A rotating gear is sleeved on the rotating shaft. The rotating gear is meshed with the lifting toothed plate.

[0009] Further: An L-shaped plate is installed on the right side wall of the sealed box, and an electric telescopic rod is provided on the L-shaped plate. The telescopic end of the electric telescopic rod is connected to the side wall of the sealed baffle.

[0011] Further: A plurality of meshing grooves are formed on one side of the lifting rack close to the rotating gear, and the meshing grooves are meshed with the rotating gear.

[0012] Further: A sealing gasket is provided on one side of the sealed baffle close to the feeding channel.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The impurities in the waste gas entering the catalytic combustion treatment device can be filtered by the filter mesh plate of the present utility model, improving the effect of waste gas catalytic combustion. By the operation of the reduction motor, the rotating gear on the rotating shaft can be driven to rotate.

[0020] Embodiment 1:

[0021] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a catalytic combustion treatment device provided with a recovery component, including a treatment box body 1, a flame arrester 2 is connected to the treatment box body 1 in a communicating manner, an air inlet of the flame arrester 2 is installed with a communicating sealing box 3, and a filter screen plate 13 is connected to the inner wall of the sealing box 3. An exhaust gas inlet pipe 5 is provided on the outer side wall of the sealing box 3 in a communicating manner. A fixed box 4 is installed on the top of the sealing box 3, and a lifting rack 7 is vertically slidably connected in the fixed box 4. A cleaning plate 14 is provided at the bottom of the lifting rack 7, and the side wall of the cleaning plate 14 is attached to the side wall of the filter screen plate 13. A blanking channel 10 is installed at the bottom of the sealing box 3 in a communicating manner, and a sealing baffle 15 is horizontally slidably connected in the blanking channel 10.

[0022] The published number is CN218583182U, an energy-saving catalytic combustion device, which mentions a recovery component. This is the prior art, and the specific structure and working principle will not be described here. Before use, the electrical ends of each electrical device are electrically connected to the external power supply and the electrical end of the controller. The exhaust gas enters the sealing box 3 through the exhaust gas inlet pipe 5. The impurities in the exhaust gas entering the catalytic combustion treatment device can be filtered through the filter screen plate 13, improving the effect of exhaust gas catalytic combustion. The vertical sliding of the lifting rack 7 can drive the cleaning plate 14 at the bottom to quickly clean the impurities on the filter screen plate 13. The impurities are discharged through the blanking channel 10, eliminating the need for manual cleaning after disassembling the filter screen plate 13, improving work efficiency and not affecting the normal operation of the catalytic combustion treatment device. When there is no need to clean the filter screen plate 13, the cleaning plate 14 is located at the bottom of the inner cavity of the fixed box 4, and the sealing baffle 15 blocks the blanking channel 10 to play a sealing role and prevent exhaust gas leakage.

[0023] Among them, preferably, a reduction motor 6 is connected to the outer wall of the front end of the fixed box 4, and a rotating shaft 11 is installed at the output end of the reduction motor 6.

The operation of the reduction motor 6 drives the rotating gear 12 fixedly connected to the rotating shaft 11 to rotate. Since the rotating gear 12 is meshed with the lifting tooth plate 7, the lifting tooth plate 7 drives the cleaning plate 14 to move up and down to clean the impurities on the filter mesh plate 13.

[0024] Preferably, an L-shaped plate 8 is installed on the right side wall of the sealing box 3, and an electric telescopic rod 9 is provided on the L-shaped plate 8. The telescopic end of the electric telescopic rod 9 is connected to the side wall of the sealing baffle 15; when it is not necessary to clean the filter mesh plate 13, the sealing baffle 15 blocks the material discharging channel 10. When cleaning is required, when the electric telescopic rod 9 works, the sealing baffle 15 moves outwards to separate from the inner wall of the material discharging channel 10. At this time, the impurities can be discharged when cleaning the filter mesh plate 13.

[0025] Preferably, openings for passing through the lifting tooth plate 7 are formed at the top, the top end and the bottom end of the sealing box 3 and the fixed box 4.

[0026] Preferably, a plurality of groups of meshing grooves are formed on the surface of the lifting tooth plate 7 close to the rotating gear 12, and the meshing grooves are meshed with the rotating gear 12.
