[0002] A deactivated catalyst treatment dust collection device is designed for collecting dust generated during the deactivated catalyst treatment process. Its design and function are generally intended to efficiently and safely collect and treat the dust generated during the catalyst deactivation process; reduce the pollution of the equipment operating environment caused by dust; and centrally process the collected dust.

[0003] The existing Chinese utility model patent with application number CN202120123610.6 relates to a regenerated catalyst dust collector, which includes a wind box, an exhaust hood, a channel, a water-based filter cotton mesh, a U-shaped frame, a handle, a door, a plug plate, and a limiting plate, etc., which can facilitate operators to clean and replace the filter plate.

[0004] However, the aforementioned device does not have the ability to clean the filter plates during continuous production and relies on manual maintenance. It is difficult to stop the machine for maintenance during continuous production, which affects production efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a dust collection device for deactivated catalyst treatment. This device absorbs the smoke and dust generated during the deactivated catalyst treatment process, intercepts large-diameter particles in the smoke and dust, filters and collects the dust from the intake air through a filtration device, outputs the dust uniformly, and uses a cleaning device to assist in cleaning the filtration device, enabling the equipment to have self-cleaning capabilities. This reduces the impact of downtime maintenance on production efficiency and improves the practicality of the device.

[0006] This utility model discloses a dust collection device for deactivated catalyst treatment; it includes a collection device, a filtration device, and a cleaning device. The filtration device is installed on the collection device, and the cleaning device is installed on the collection device. The collection device absorbs the smoke and dust generated during the deactivated catalyst treatment process and intercepts large-diameter particles in the smoke and dust. The filtration device filters and collects the dust from the intake air and outputs the dust uniformly. The cleaning device assists in cleaning the filtration device, enabling the equipment to have self-cleaning capabilities, reducing the impact of downtime maintenance on production efficiency, and improving the practicality of the device.

[0007] Preferably, the collection device includes a filter box, a fan, a telescopic pipe, a dust collection head, and a screen plate. The fan is installed on the side of the filter box, and the input end of the fan is connected to the bottom of the filter box. The telescopic pipe is connected to the upper part of the filter box, and the input end of the telescopic pipe is connected to the dust collection head. The input end of the dust collection head is equipped with a screen plate. By turning on the fan, the dust collection head collects the smoke and dust generated during the deactivated catalyst treatment process. The screen plate intercepts large-diameter particles in the smoke and dust. The telescopic pipe allows for easy adjustment of the working position of the dust collection head, improving the adaptability and practicality of the device.

[0008] Preferably, the filtration device includes a support frame, a filter screen, a dust collection hopper, a guide pipe, a feeding pipe, spiral blades, and a drive motor. Three sets of supports are installed obliquely from top to bottom inside the filter box, with filter screens mounted on the supports. Three sets of dust collection hoppers are located on the right end face of the filter box, with the input ends of the three dust collection hoppers connected to the bottom of the three sets of filter screens. Guide pipes are connected to the output ends of the dust collection hoppers. A feeding pipe is horizontally installed at the lower part of the right end face of the filter box, with spiral blades installed inside the feeding pipe. A drive motor is installed on the rear side of the feeding pipe, with its output end connected to the spiral blades. The output ends of the three guide pipes are connected to the inside of the feeding pipe. The filter screen filters the smoke and dust drawn into the filter box, and the dust particles fall from the bottom of the filter screen into the dust collection hopper. The dust particles then fall again through the guide pipe connected to the dust collection hopper into the feeding pipe. The drive motor is then activated, transmitting power to the spiral blades to rotate them. The rotating spiral blades cause the dust in the feeding pipe to be concentrated and discharged, improving the practicality of the device.

[0009] Preferably, the cleaning device includes a vibrating plate, support rods, a vibrating motor, and cleaning plates. A set of support rods is horizontally mounted on the upper and lower parts of the left end face of the filter box via brackets. The two sets of support rods pass through the upper and lower parts of the vibrating plate. A vibrating motor is mounted on the left end face of the vibrating plate. Three sets of cleaning plates are connected from top to bottom on the right end face of the vibrating plate. The right part of the cleaning plates extends through the left end face of the filter box into the filter box and is located below the three sets of brackets. The portions of the three sets of cleaning plates inside the filter box are inclined downwards at the same angle as the brackets. The upper end face of the cleaning plates is in close contact with the lower end face of their respective filter screens. Turning on the vibrating motor transmits power through the vibrating plate to the multiple sets of cleaning plates, causing them to vibrate. This, in turn, causes the filter screens on the upper part of the multiple sets of cleaning plates to vibrate, shaking the accumulated dust on the filter screens into the dust collection hopper. This reduces the impact of excessive dust accumulation on the filter screens on filtration efficiency. Furthermore, the equipment can complete its self-cleaning without stopping or requiring manual operation during continuous production, improving the practicality of the device.

[0010] Preferably, it also includes strip holes. A set of strip holes is provided on the upper and lower parts of the vibrating plate, and two sets of support rods are connected to the vibrating plate through the strip holes. The strip holes increase the amplitude of the vibration of the vibrating plate when the vibrating motor is turned on, thereby increasing the vibration amplitude of the cleaning plate, improving the cleaning efficiency of the equipment and the practicality of the device.

[0011] Preferably, it also includes a rubber sealing ring and rubber protective strips. A rubber sealing ring is provided in the hole through which the cleaning plate passes through the front end face of the filter box, and multiple sets of rubber protective strips are evenly installed on the upper end face of the cleaning plate. The rubber sealing ring improves the sealing performance of the filter box itself, thereby ensuring the dust collection efficiency of the equipment. The multiple sets of rubber protective strips evenly distributed on the cleaning plate reduce the scratches caused to the lower end face of the filter screen during the vibration of the cleaning plate, thus improving the practicality of the device.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the collection device absorbs the smoke and dust generated during the treatment of deactivated catalyst, and intercepts large-diameter particles in the smoke and dust; the filtration device filters and collects the dust in the intake air, and outputs the dust uniformly; the cleaning device assists in cleaning the filtration device, enabling the equipment to have self-cleaning ability, reducing the impact of downtime maintenance on production efficiency, and improving the practicality of the device.

A set of support rods 14 are horizontally installed on the upper and lower parts of the left end face of the filter box 1 via brackets. The two sets of support rods 14 pass through the upper and lower parts of the vibrating plate 13. A vibrating motor 15 is installed on the left end face of the vibrating plate 13. Three sets of cleaning plates 16 are connected from top to bottom on the right end face of the vibrating plate 13. The right part of the cleaning plates 16 extends through the left end face of the filter box 1 into the interior of the filter box 1 and is located on the lower side of the three sets of brackets 6. The parts of the three sets of cleaning plates 16 inside the filter box 1 are inclined downward and have the same inclination angle as the brackets 6.

[0028] The collection device absorbs the smoke and dust generated during the deactivated catalyst treatment process, while intercepting large-diameter particles in the smoke and dust. The filtration device filters and collects the dust in the intake air and outputs the dust uniformly. The cleaning device assists in cleaning the filtration device, enabling the equipment to have self-cleaning capabilities, reducing the impact of downtime maintenance on production efficiency, and improving the practicality of the equipment.

[0029] like Figures 1 to 5 As shown, this utility model discloses a dust collection device for deactivated catalyst treatment. During operation, the fan 2 is first turned on to collect the dust generated during the deactivated catalyst treatment process using the dust collection head 4. Large-diameter particles in the dust are intercepted by the screen plate 5. Then, the dust drawn into the filter box 1 is filtered through the filter screen 7. Dust particles fall from the bottom of the filter screen 7 into the dust collection hopper 8. The dust particles then fall again through the guide pipe 9 connected to the dust collection hopper 8 into the feeding pipe 10. Next, the drive motor 12 is turned on to transmit power to the spiral blades 11, causing them to rotate. The rotating spiral blades 11 cause the dust in the feeding pipe 10 to be concentrated and output. Then, the vibration motor 15 is turned on periodically to transmit power through the vibration plate 13 to multiple sets of cleaning plates 16, causing them to vibrate. This vibrates the filter screen 7 on the upper side of the multiple sets of cleaning plates 16, shaking the accumulated dust on the filter screen 7 into the dust collection hopper 8.
