Description

Technical Field

[0001] This utility model relates to the field of purification device technology, specifically a VOCs purification device. Background Technology

[0002] VOCs purification devices are environmental protection equipment that treat volatile organic compounds (VOCs). The core technology uses adsorption, catalytic combustion, photocatalytic oxidation and other technologies to decompose or convert VOCs emitted from industrial production, painting, chemical and other scenarios into harmless substances, so as to prevent them from polluting the air and harming human health. It is a key device for achieving the standard emission of waste gas and helping environmental governance.

[0003] Existing purification devices often clog filters due to impurities in the gas, requiring frequent cleaning by staff and reducing work efficiency. Therefore, we propose a VOCs purification device. Utility Model Content

[0004] The purpose of this invention is to provide a VOCs purification device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A VOCs purification device includes a pipe and further includes: A rectangular plate is inserted into a pipe. A sliding groove is provided in the rectangular plate, and two limiting posts are slidably installed in the sliding groove. Both limiting posts are inserted into the pipe. Two fixed frames are inserted into a rectangular plate, and a filter screen is fixedly installed in each of the two fixed frames. A power cavity is opened in the rectangular plate, and two limiting plates are slidably installed in the power cavity. The two limiting plates are respectively inserted into and cooperate with the two fixed frames. A drive assembly located within the filter screen and used to drive the two limiting posts to slide. A power assembly, located within the filter screen, drives the two limiting plates to slide. This drive assembly allows the limiting posts to slide within the sliding grooves. The limiting posts engage with the pipe, enabling rapid fixation of the rectangular plate within the pipe. The power component can drive the limiting plate to slide. The limiting plate is inserted into the fixed frame to fix the fixed frame and the filter screen within the rectangular plate. The filter screen at the top has a larger pore size than the one at the bottom, which can perform graded filtration of VOCs and improve the purification effect.

[0006] Preferably, the driving component includes: A first bevel gear is rotatably mounted within a sliding groove. Two second bevel gears are meshed with one side of the first bevel gear. Each of the two second bevel gears has a threaded rod fixedly mounted at one end, with one end of each threaded rod extending into one of the two limiting posts. The threaded rods are threadedly connected to the two limiting posts. Rotating the first bevel gear causes the two second bevel gears to rotate synchronously, which in turn causes the corresponding threaded rods to rotate. These threaded rods then cause the limiting posts to slide within the sliding groove. The limiting posts engage with the pipe, enabling the rectangular plate to be quickly fixed within the pipe.

[0007] Preferably, the power assembly includes: A sliding plate is slidably installed within a power chamber. Several fixed posts are fixedly installed on one side of the sliding plate, each post fitted with a spring. Two guide grooves are formed on the sliding plate, and guide posts are slidably installed within each groove. The guide posts are fixedly connected to two limiting plates, and the fixed posts are slidably connected to the power chamber. The sliding plate can slide within the power chamber, moving the fixed posts. The springs assist in resetting the sliding plate. The sliding plate moves the guide posts via the guide grooves, which in turn move the limiting plates. The limiting plates are inserted into a fixed frame, securing the frame and filter screen within the rectangular plate. The upper filter screen has a larger pore size than the lower one, allowing for graded filtration of VOCs and improving purification efficiency.

[0008] Preferably, an operating lever is fixedly mounted on one end of the first bevel gear, and one end of the operating lever passes through the sliding groove and extends to the outside. The operating lever is rotatably connected to the sliding groove. This operating lever allows the operator to easily rotate the first bevel gear.

[0009] Preferably, the pore size of the upper filter screen is larger than that of the lower filter screen. This allows for tiered filtration of VOCs, improving the purification effect.

[0010] Preferably, the guide groove is inclined. This ensures that the sliding plate can drive the guide post to move through the guide groove.

[0011] Preferably, both ends of the spring are fixedly connected to the inner wall of the power chamber and the sliding plate, respectively, to ensure stable use of the spring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This VOCs purification device, through its set drive component, can drive the limiting column to slide within the sliding groove. The limiting column is inserted into the pipe to achieve rapid fixation of the rectangular plate within the pipe.
