A VOC treatment device

Abstract

The application discloses a VOC treatment device, which comprises a positioning device arranged on the outer surface of a rotating shaft and capable of providing arbitrary-angle fixation for a purification device, and mainly comprises a fixing ring and a clamping block. The VOC treatment device is provided with the positioning device. When in use, the clamping block needs to be pulled to both sides at the same time. At this time, the clamping block drives the blocking blocks on both sides to move to both ends upward and downward, so that the blocking blocks contact and shield the fixing ring. At this time, the gear can be placed inside the fixing ring. At this time, the release of the reset springs on both sides of the clamping block resets the position, so that the clamping block limits the angle of the gear. Meanwhile, the blocking blocks on both sides need to be close to each other. At this time, the magnetic blocks on the blocking blocks on both sides are attracted to each other due to magnetic force, thereby limiting the angle and position of the gear inside the fixing ring, so that the dismounting and mounting efficiency of the purification device is higher.

Description

Technical Field

[0001] This invention relates to the field of gas treatment technology, and in particular to a VOC treatment device. Background Technology

[0002] VOCs are mainly volatile organic compounds, but in the field of environmental protection, they are mainly considered to be a type of harmful volatile organic compound that is relatively reactive and easily reacts with external chemicals. This volatile gas has a huge impact on human health, and long-term exposure to this gas can cause serious consequences such as damage to internal organs.

[0003] In existing VOC gas treatment devices, activated carbon is mainly used to adsorb VOC gases. However, activated carbon plates with different pore sizes have different adsorption effects on different VOC gases. Moreover, the activated carbon plates in existing equipment are mostly integrated designs, which are often cumbersome to disassemble and replace. In view of this, we propose a VOC treatment device. Summary of the Invention

[0004] The main objective of this invention is to provide a VOC treatment device that can fix the purification device at any angle.

[0005] To achieve the above objectives, the present invention proposes a VOC treatment device, including a positioning device disposed on the outer surface of a rotating shaft, capable of fixing the purification device at any angle. The positioning device includes: A fixed ring, the end of which is fixedly connected to a rotating shaft, and the inside of the fixed ring is provided with two sets of sliding grooves; The card block has a retaining ring slidably connected to its outer surface.

[0006] Preferably, the card block has a groove inside, a slider is slidably connected inside the card block, and a stop block is fixedly connected to the outer surface of the slider. The stop block is provided in two sets and the two sets of stop blocks are symmetrically distributed with the center line of the fixed ring as the axis of symmetry.

[0007] Preferably, a magnetic block is fixedly connected to the end of the stop block, a return spring is fixedly connected to the outer surface of the card block, and a fixing ring is fixedly connected to the end of the return spring away from the card block.

[0008] Preferably, the output shaft of a motor is fixedly connected to the end of the rotating shaft, a housing is rotatably connected to the outer surface of the rotating shaft, a housing is fixedly connected to the outer surface of the motor, an air inlet is connected to the upper end of the housing, an exhaust port is connected to the side surface of the housing, and a pressurizing device is provided on the upper surface of the housing.

[0009] Preferably, the pressurizing device includes a one-way valve, a housing is fixedly connected to the outer surface of the one-way valve, a pressure gauge is connected to the upper surface of the housing, an arc-shaped pipe is connected to the upper end of the one-way valve, and a pressurizing tank is connected to the end of the arc-shaped pipe away from the one-way valve.

[0010] Preferably, the outer surface of the pressurizing tank is in contact with a positioning block, the outer surface of the positioning block is fixedly connected to a housing, the one-way valve is unidirectionally downward, and a funnel-shaped sealing cover is provided at the connection between the one-way valve and the arc-shaped pipe.

[0011] Preferably, the purification device includes a gear, the outer surface of the gear is in contact with a fixed ring, a fixed shaft is fixedly connected to the outer surface of the gear, and an adsorption plate is rotatably connected to the end of the fixed shaft away from the gear.

[0012] Preferably, connecting brackets are fixedly connected to both sides of the fixed shaft. The connecting brackets are L-shaped, and a groove is provided at the end of the connecting bracket away from the fixed shaft. A compression spring is fixedly connected in the groove inside the connecting bracket.

[0013] Preferably, a compression block is fixedly connected to the end of the compression spring away from the connecting frame, and the compression block is a metal block with a rubber surface.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) The VOC treatment device is equipped with a positioning device. When in use, the locking block needs to be pulled up and down on both sides at the same time. At this time, the locking block will drive the two side blocks to move up and down at both ends, so that the blocks contact the blocking of the fixed ring. At this time, the gear can be placed inside the fixed ring. When the reset springs on both sides of the locking block are released, the position will be reset, so that the locking block will limit the angle of the gear. At the same time, the two side blocks need to be brought close to each other. At this time, the magnetic blocks on the two side blocks will attract each other due to magnetic force, thereby limiting the angle and position of the gear inside the fixed ring, so that the disassembly and installation efficiency of the purification device is high.

[0015] (2) The VOC treatment device is equipped with a pressurization device. During purification, the exhaust port of the pressurization tank needs to be opened according to the different VOC gases being purified. At this time, the pressurization tank will continuously fill the box with inert gas through the arc-shaped pipe and the one-way valve, thereby increasing the gas pressure inside the box. At the same time, during the pressurization process, the user can simultaneously pressurize and purify by using the pressure gauge connected to the top of the box, thereby improving the purification efficiency of the adsorption plate for the VOC gas inside the box. Meanwhile, due to the function of the one-way valve, the gas entering the box cannot leak out, thus ensuring the safety of VOC gas purification of this device.

[0016] (3) The VOC treatment device is equipped with a purification device. When the motor starts, it will drive the rotating shaft at the output shaft to rotate continuously. At this time, due to the rotational connection between the fixed shaft and the adsorption plate, the adsorption plate will swing due to air resistance when the rotating shaft rotates. At this time, the adsorption plate will contact the squeezing block at the end of the connecting frame. At this time, the squeezing block will push the adsorption plate to rotate in the opposite direction due to the action of the spring, thereby realizing the continuous swing of the adsorption plate during the VOC gas purification process, thereby accelerating the air flow rate inside the box and increasing the adsorption effect of the adsorption plate.

Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0023] Please see Figures 1-4 The present invention provides a technical solution: a VOC treatment device, including a positioning device 2, which is disposed on the outer surface of a rotating shaft 5 and can provide arbitrary angle fixation for a purification device 4. The end of the rotating shaft 5 is fixedly connected to the output shaft of a motor 6. The outer surface of the rotating shaft 5 is rotatably connected to a housing 1. A door controlled by a key is provided on the back of the housing 1. The outer surface of the motor 6 is fixedly connected to the housing 1. The upper end of the housing 1 is connected to an air inlet, and the side surface of the housing 1 is connected to an exhaust outlet. Valves for controlling the flow rate are provided at both the air inlet and the exhaust outlet. A pressurizing device 3 is provided on the upper surface of the housing 1.

[0024] In this embodiment of the invention, the positioning device 2 includes: The fixed ring 205 is fixedly connected to the rotating shaft 5 at its end. The fixed ring 205 has two sets of sliding grooves inside. These sliding grooves can limit the movement trajectory of the locking block 204, thereby preventing it from deviating during movement. The outer surface of the locking block 204 is slidably connected to the fixing ring 205. The locking block 204 can be embedded in the tooth groove on the surface of the gear 405, thereby limiting the angle of the gear 405.

[0025] Specifically, the card block 204 has a groove inside, and the inside of the card block 204 is slidably connected to the slider 206. The outer surface of the slider 206 is fixedly connected to the stop block 201. The stop block 201 has a semi-circular groove inside, which can prevent it from interfering with the movement of the fixed shaft 404. There are two sets of stop blocks 201, and the two sets of stop blocks 201 are symmetrically distributed about the center line of the fixed ring 205. The ends of the stop blocks 201 are fixedly connected to the magnetic blocks 203. The contact surfaces of the upper and lower sets of magnetic blocks 203 have opposite polarities, so they can generate a certain attraction when they come into contact. The outer surface of the card block 204 is fixedly connected to the return spring 202. The end of the return spring 202 away from the card block 204 is fixedly connected to the fixed ring 205. This VOC treatment device is designed with... The device is equipped with a positioning device 2. When in use, the locking block 204 needs to be pulled up and down simultaneously. At this time, the locking block 204 will drive the stop blocks 201 on both sides to move up and down, so that the stop blocks 201 contact the blocking ring 205. Then, the gear 405 can be placed inside the fixing ring 205. When the reset springs 202 on both sides of the locking block 204 are released, their positions will be reset, so that the locking block 204 will limit the angle of the gear 405. At the same time, the stop blocks 201 on both sides need to be brought closer to each other. At this time, the magnetic blocks 203 on the stop blocks 201 on both sides will attract each other due to magnetic force, thereby limiting the angle and position of the gear 405 inside the fixing ring 205, thus making the disassembly and installation of the purification device 4 more efficient.

[0026] In this embodiment of the invention, the pressurizing device 3 includes a one-way valve 302. The outer surface of the one-way valve 302 is fixedly connected to the housing 1. The upper surface of the housing 1 is connected to a pressure gauge 301, thus allowing real-time monitoring of the air pressure inside the housing 1. The upper end of the one-way valve 302 is connected to an arc-shaped pipe 303, and the end of the arc-shaped pipe 303 away from the one-way valve 302 is connected to a pressurizing tank 304. The pressurizing tank 304 is filled with neon gas. Since neon gas is an inert gas, it is not easy for it to react chemically with the VOC gas inside the housing 1. The outer surface of the pressurizing tank 304 is in contact with a positioning block 305, and the outer surface of the positioning block 305 is fixedly connected to the housing 1. The one-way valve 302 is unidirectionally downward, thus preventing the gas inside the housing 1 from flowing back into the pressurizing tank 304. The unit has a funnel-shaped sealing cover at the connection between the one-way valve 302 and the arc-shaped pipe 303. The VOC treatment device is equipped with a pressurizing device 3. During purification, the exhaust port of the pressurizing tank 304 needs to be opened depending on the type of VOC gas being purified. At this time, the pressurizing tank 304 will continuously fill the chamber 1 with inert gas through the arc-shaped pipe 303 and the one-way valve 302, thereby increasing the gas pressure inside the chamber 1. During the pressurization process, the user can simultaneously pressurize and purify the gas by using the pressure gauge 301 connected to the upper end of the chamber 1, thereby improving the purification efficiency of the adsorption plate 401 for the VOC gas inside the chamber 1. At the same time, due to the function of the one-way valve 302, the gas entering the chamber 1 cannot leak out, thus ensuring the safety of VOC gas purification of this device.

[0027] In this embodiment of the invention, the purification device 4 includes a gear 405. The outer surface of the gear 405 contacts a fixed ring 205 and is fixedly connected to a fixed shaft 404. The end of the fixed shaft 404 away from the gear 405 is rotatably connected to an adsorption plate 401. The adsorption plate 401 is made of porous activated carbon, thus it can fully adsorb VOC gas inside the housing 1. Both sides of the fixed shaft 404 are fixedly connected to a connecting frame 403. The connecting frame 403 is L-shaped, and a groove is provided at the end of the connecting frame 403 away from the fixed shaft 404. A compression spring is fixedly connected to the groove inside the connecting frame 403. The end of the compression spring away from the connecting frame 403 is fixedly connected to a compression block 402. The compression block 402 is a metal block with a rubber surface. Therefore, it can prevent direct rigid collision between the squeezing block 402 and the adsorption plate 401, which would damage the adsorption plate 401. The VOC treatment device is equipped with a purification device 4. When the motor 6 starts, it will drive the rotating shaft 5 at the output shaft to rotate continuously. At this time, since the fixed shaft 404 is rotatably connected to the adsorption plate 401, the adsorption plate 401 will swing due to air resistance when the rotating shaft 5 rotates. At this time, the adsorption plate 401 will contact the squeezing block 402 at the end of the connecting frame 403. At this time, the squeezing block 402 will push the adsorption plate 401 to rotate in the opposite direction due to the action of the spring, thereby realizing the continuous swing of the adsorption plate 401 during the VOC gas purification process, thereby accelerating the air flow rate inside the box 1 and increasing the adsorption effect of the adsorption plate 401.

[0028] During operation (or use), it is necessary to select an adsorption plate 401 with a suitable pore size according to the specific VOC gas. At this time, the locking blocks 204 need to be pulled up and down simultaneously. The locking blocks 204 will then move the stop blocks 201 on both sides up and down, causing the stop blocks 201 to contact the blocking ring 205. The gear 405 can then be placed inside the fixing ring 205. Releasing the return springs 202 on both sides of the locking blocks 204 will reset its position, thus limiting the angle of the gear 405. The two side blocks 201 need to be brought closer together. At this time, the magnetic blocks 203 on the two side blocks 201 will attract each other due to magnetic force, thereby limiting the angle and position of the gear 405 inside the fixing ring 205, thus making the disassembly and installation of the purification device 4 more efficient. When the installation is completed, the exhaust port on the side surface of the box 1 needs to be sealed, and VOC gas is supplied to the air inlet at the top of the box 1. At this time, VOC gas will gradually fill the inside of the box 1. Then, the motor 6 is started. When the motor 6 starts, it will drive the rotating shaft 5 at the output shaft to rotate continuously. Because the fixed shaft 404 is rotatably connected to the adsorption plate 401, the adsorption plate 401 will swing due to air resistance when the rotating shaft 5 rotates. At this time, the adsorption plate 401 will contact the pressing block 402 at the end of the connecting frame 403. The pressing block 402 will then push the adsorption plate 401 to rotate in the opposite direction due to the action of the spring. This results in the continuous swinging of the adsorption plate 401 during the VOC gas purification process, thereby accelerating the airflow inside the chamber 1 and increasing the adsorption effect of the adsorption plate 401. Furthermore, depending on the type of VOC gas being purified... To open the exhaust port of the pressurizing tank 304, the pressurizing tank 304 will continuously fill the chamber 1 with inert gas through the arc-shaped pipe 303 and the one-way valve 302, thereby increasing the gas pressure inside the chamber 1. At the same time, during the pressurization process, the user can simultaneously pressurize and purify the gas by using the pressure gauge 301 connected to the upper end of the chamber 1, thereby improving the purification efficiency of the adsorption plate 401 for the VOC gas inside the chamber 1. Meanwhile, due to the function of the one-way valve 302, the gas entering the chamber 1 cannot leak out, thus ensuring the safety of VOC gas purification of this device.
