Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, specifically a device for treating volatile organic pollutants in waste gas. Background Technology

[0002] Volatile organic pollutants (VOCs) in waste gas are a class of organic compounds that easily evaporate at room temperature. They originate from a wide range of industries, including chemical, coating, printing, and pharmaceutical manufacturing. These pollutants not only cause serious air pollution, leading to problems such as photochemical smog and ozone pollution, but also pose health risks, such as irritating the respiratory tract and affecting the nervous system. Therefore, waste gas treatment is necessary. However, during the waste gas treatment process, the waste gas generally carries a large amount of dust. If this dust is not filtered in a timely manner, it will damage subsequent treatment equipment.

[0003] For example, utility model patent CN202022069551.7 discloses an easy-to-replace exhaust gas treatment device, including a housing. An inlet pipe is fixedly connected to the middle left side of the housing, and an outlet pipe is fixedly connected to the middle right side of the housing. A first groove is formed in the middle of the inner wall of both the front and back sides of the housing. A telescopic spring is fixedly connected to the inner bottom wall of the first groove. A placement plate is fixedly connected to the end of the telescopic spring away from the inner bottom wall of the first groove. The placement plate is U-shaped, and a placement groove is formed on the inner wall of the placement plate, in which a filter element is placed. This easy-to-replace exhaust gas treatment device allows the cover plate to move to the right by pulling the handle. Due to the reaction force of the telescopic spring, the spring returns to its original shape, thereby moving the placement plate and filter element upwards. The placement plate is then higher than the U-shaped frame, allowing the filter element to be pulled out from the placement groove for replacement. This exhaust gas treatment device is simple to operate and facilitates filter element replacement.

[0004] The aforementioned patent provides a treatment device for filtering dust in exhaust gas that allows for easy replacement of the filter element. However, the filter element in this device is set vertically, and as the airflow moves, dust will gradually be adsorbed onto the filter element, which not only affects the filtration efficiency of the filter element but also requires frequent replacement by staff, reducing the treatment efficiency and requiring further improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a volatile organic pollutant volatile waste gas treatment device, which aims to improve the problem in the existing waste gas treatment device where the filter element is set vertically, causing dust to be gradually adsorbed on the filter element with the airflow, which not only affects the filter element filtration efficiency, but also requires frequent replacement by the staff, thus reducing the treatment efficiency.

[0006] This utility model is implemented as follows:

[0007] A device for treating volatile organic pollutants (VOCs) includes a treatment tank and an inlet pipe. The outlet of the inlet pipe extends into the interior of the treatment tank. The device also includes a mounting frame. From top to bottom, the treatment tank contains a tank lid, a filter plate, and the mounting frame. From top to bottom, the mounting frame contains a cleaning device and a resilient plug. The cleaning device is rotatably mounted on the mounting frame, with a cleaning brush at its upper end abutting against the lowest point of the filter plate, and a transmission connecting plate fixedly mounted at its lower end. The resilient plug is elastically mounted on the mounting frame, with its lower end elastically abutting against the outlet of the inlet pipe, and its upper end located below the transmission connecting plate. A rotating fan is rotatably mounted on the outer ring surface of the resilient plug, and the upper end of the rotating fan is movably connected to the transmission connecting plate.

[0008] Preferably, it also includes multiple latches, and the bucket lid is installed on the processing bucket by multiple latches.

[0009] Preferably, it also includes a cleaning cover, which is rotatably installed on the side of the treatment tank near the lower end. A locking bolt is provided at one end of the cleaning cover, and the locking bolt is installed on the tank body of the treatment tank.

[0010] Preferably, the mounting bracket includes a first mounting sleeve, a second mounting sleeve, and a second mounting support rod; a plurality of first mounting support rods are sequentially arranged on the outer circumferential surface of the first mounting sleeve, and mounting bolts are provided at the ends of the first mounting support rods, which are fixedly installed on the inner wall of the treatment tank; the second mounting sleeve is coaxially arranged below the first mounting sleeve through the second mounting support rod, and a plurality of third mounting sleeves are sequentially arranged on the upper end surface of the second mounting sleeve along its circumferential direction; the cleaning device is rotatably installed in the first mounting sleeve, and a corresponding sliding rod is provided at the lower end of the elastic plug corresponding to the position of each third mounting sleeve, the sliding rod being elastically installed in the third mounting sleeve; the air inlet pipe is fixedly installed in the second mounting sleeve.

[0011] Preferably, the cleaning device further includes a mounting shaft, which is rotatably mounted in a first mounting sleeve. Multiple cleaning brushes are sequentially arranged at the upper end along its circumference, and a transmission connecting plate is fixedly arranged at the lower end.

[0012] Preferably, the elastic plug further includes a limiting platform, and the sliding rod is provided with a limiting platform and a first return spring from top to bottom. The limiting platform is abutted against the upper end face of the third mounting sleeve, and the first return spring abuts against the lower end face of the third mounting sleeve.

[0013] Preferably, the rotating fan includes an elastic transmission head and a second return spring; multiple elastic transmission heads are sequentially arranged on the upper end surface of the rotating fan along its circumference, and the elastic transmission heads are elastically extendable and retractable by the second return spring; the transmission connecting plate is provided with a one-to-one corresponding transmission hole for each elastic transmission head, and the elastic transmission head can be movably inserted into the transmission hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by placing the air inlet pipe below the filter plate and flexibly installing an elastic plug at the inlet of the air inlet pipe that can be automatically opened by airflow, as well as a cleaning device driven by airflow, not only can the filter plate be cleaned while working, but the cleaned dust can also fall to the bottom of the processing bucket, preventing a large amount of dust from adhering to the filter plate. At the same time, when not working, the elastic plug can also be used to seal the air inlet pipe to prevent a large amount of dust from flowing back into the air inlet pipe when the air intake stops.

[0016] 2. This utility model reduces the distance between the rotating fan and the air inlet pipe by rotating the fan in place on the elastic plug. This avoids the problem that the airflow would be affected by the elastic plug and unable to blow the fan. At the same time, as the elastic plug rises, the rotating fan allows the elastic transmission head to be inserted into the transmission hole of the cleaning device, thereby driving the cleaning device to rotate. This allows the elastic plug and the cleaning device to work together without interfering with each other. Attached Figure Description

[0027] Example 1

[0028] like Figures 1-3 As shown, a volatile organic pollutant (VOC) waste gas treatment device includes a treatment tank 1 and an inlet pipe 5. The outlet of the inlet pipe 5 extends into the interior of the treatment tank 1. It also includes a mounting frame 10. From top to bottom, the treatment tank 1 is equipped with a tank cover 2, a filter plate 6, and the mounting frame 10. From top to bottom, the mounting frame 10 is equipped with a cleaning device 7 and a flexible plug 8. It also includes multiple latches 3 and a cleaning cover 4. The tank cover 2 is mounted on the treatment tank 1 via the latches 3. A cleaning cover 4 is rotatably mounted on the side of the treatment tank 1 near the lower end. A locking bolt 401 is provided at one open / closed end of the cleaning cover 4, and the locking bolt 401 is mounted on the tank body of the treatment tank 1. The upper end of the tank cover 2 has a waste gas outlet connecting to the next process. The cleaning cover 4 facilitates the cleaning of dust and impurities filtered out inside the treatment tank 1. The filter plate 6 has multiple layers. The opening of the treatment tank 1 is equipped with an installation platform that is compatible with the filter plate 6. The filter plates 6 are stacked one by one at the opening of the treatment tank 1.

[0029] like Figures 3-6As shown, the mounting bracket 10 includes a first mounting sleeve 1001, a second mounting sleeve 1004, and a second mounting support rod 1005. Multiple first mounting support rods 1002 are sequentially arranged along the circumferential direction on the outer ring surface of the first mounting sleeve 1001. Mounting bolts 1003 are provided at the ends of the first mounting support rods 1002, and the mounting bolts 1003 are fixedly installed on the inner wall of the processing tank 1. The second mounting sleeve 1004 is coaxially arranged below the first mounting sleeve 1001 via the second mounting support rods 1005. Multiple third mounting sleeves 1006 are sequentially arranged along the circumferential direction on the upper end surface of the second mounting sleeve 1004. The second mounting support rod 1005 is fixedly connected to the first mounting support rod 1002 by welding or screw installation. The cleaning device 7 is rotatably installed in the first mounting sleeve 1001. The cleaning device 7 also includes a mounting shaft 701, which is rotatably installed in the first mounting sleeve 1001. Multiple cleaning brushes 702 are sequentially arranged along the circumference of its upper end, and a transmission connecting plate 703 is fixedly installed at its lower end. A corresponding sliding rod 801 is provided at the lower end of each third mounting sleeve 1006, and the sliding rod 801 is elastically installed in the third mounting sleeve 1006. The lower end face of the third mounting sleeve 1006 extends to the lower end face of the second mounting sleeve 1004, thus allowing the upper and lower ends of the third mounting sleeve 1006 to be connected. The air intake pipe 5 is fixedly installed in the second mounting sleeve 1004. The elastic plug 8 also includes a limiting platform 802. The sliding rod 801 is sequentially equipped with the limiting platform 802 and a first return spring 803 from top to bottom. The limiting platform 802 abuts against the upper end face of the third mounting sleeve 1006, and the first return spring 803 abuts against the lower end face of the third mounting sleeve 1006. The elastic plug 8 abuts against the inlet of the air inlet pipe 5. When the device is not in use, the elastic plug 8 can block the air inlet pipe 5 to prevent dust from flowing back into it. During use, airflow can blow up the elastic plug 8, allowing exhaust gas to enter the treatment tank 1 for filtration. The elastic plug 8 is elastically supported by the first return spring 803, allowing it to automatically reset and re-block the air inlet pipe 5 when there is no airflow.

[0030] like Figure 3 and Figures 5-6As shown, the cleaning device 7 is rotatably mounted on the mounting frame 10, with a cleaning brush plate 702 abutting against the lowest end of the filter plate 6 at its upper end, and a transmission connecting plate 703 fixedly mounted at its lower end; the elastic plug 8 is elastically mounted on the mounting frame 10, with its lower end elastically abutting against the air outlet of the air inlet pipe 5, and its upper end located below the transmission connecting plate 703; a rotating fan 9 is rotatably mounted on the outer ring surface of the elastic plug 8, and the upper end of the rotating fan 9 is movably connected to the transmission connecting plate 703. The rotating fan 9 includes an elastic transmission head 901 and a second return spring 902; multiple elastic transmission heads 901 are sequentially arranged along the circumference of the upper end surface of the rotating fan 9, and the elastic transmission heads 901 are elastically extendable and retractable by the second return spring 902; the transmission connecting plate 703 is provided with a one-to-one corresponding transmission hole 704 corresponding to the position of each elastic transmission head 901, and the elastic transmission head 901 can be movably inserted into the transmission hole 704. A rotating fan 9 is rotatably mounted on the outer ring surface of the elastic plug 8. As the elastic plug 8 moves upward with the airflow, it simultaneously drives the rotating fan 9 upward. The curved surface of the end face where the elastic plug 8 and the air inlet pipe 5 meet guides the airflow towards the rotating fan 9, thus causing it to rotate. This allows the elastic drive head 901 on the rotating fan 9 to be inserted into the drive hole 704, driving the cleaning device 7 to rotate. The elastic drive head 901 is retractable, automatically retracting even if it is not aligned with the drive hole 704, without affecting the upward movement of the elastic plug 8. Furthermore, during the rotation of the rotating fan 9, the elastic drive head 901 automatically aligns with the drive hole 704 and is automatically inserted, driving the cleaning device 7 to rotate and clean the lower end of the filter plate 6, preventing dust from adhering to it and affecting the filtration effect.
