[0028] The following is for reference. Figure 1 and Figure 2This invention describes a volatile organic compound purification device according to an embodiment of the present invention.
[0029] The volatile organic compound purification device according to an embodiment of the present invention includes an air inlet channel 100, an exhaust channel 200, an absorption mechanism, and a control component.
[0030] The air intake channel 100 is arranged horizontally, and the air intake channel 100 can be a circular tube-shaped air duct.
[0031] The exhaust channel 200 is arranged horizontally. The exhaust channel 200 can be a circular tube-shaped air duct. The exhaust channel 200 is coaxial with the air intake channel 100. The exhaust channel 200 and the air intake channel 100 are arranged horizontally at intervals. The exhaust channel 200 is located directly to the right of the air intake channel 100.
[0032] The absorption mechanism includes a support frame 400 and a driver. The support frame 400 is disposed between the exhaust channel 200 and the intake channel 100. The support frame 400 has two absorption channels 410, one of which is called the first channel and the other is called the second channel. The first channel is located in front of the second channel. Both absorption channels 410 are circular tubular air ducts. Both absorption channels 410 are adapted to the exhaust channel 200 and the intake channel 100. The two absorption channels 410 are arranged at intervals. Both absorption channels 410 are detachably provided with absorption components 412. The absorption components 412 are used to absorb volatile organic compounds in the gas. One of the absorption channels 410 is disposed between the intake channel 100 and the exhaust channel 200.
[0033] The actuator is used to drive the support frame 400 to move back and forth. The actuator can be a cylinder, an electric push rod or other suitable linear actuator. The actuator drives the support frame 400 to move back and forth in a first state and a second state. In the first state, the actuator drives the support frame 400 backward, so that the support frame 400 moves to its rearmost position. The first channel is located between the exhaust channel 200 and the intake channel 100. The intake channel 100, the first channel and the exhaust channel 200 are coaxial, so that the intake channel 100 and the exhaust channel 200 are connected through the first channel. This allows the absorber 412 set in the first channel to absorb volatile organic compounds in the airflow from the intake channel 100 to the exhaust channel 200. At this time, the second channel protrudes backward from the intake channel 100 and the exhaust channel 200 so that the absorber 412 set in the second channel can be replaced.
[0034] In the second state, the driver drives the support frame 400 forward, moving the support frame 400 to its front limit position. The second channel is located between the exhaust channel 200 and the intake channel 100. The intake channel 100, the second channel, and the exhaust channel 200 are coaxial, so that the intake channel 100 and the exhaust channel 200 are connected through the second channel. This allows the absorber 412 disposed in the second channel to absorb volatile organic compounds in the airflow from the intake channel 100 to the exhaust channel 200. At this time, the first channel protrudes forward from the intake channel 100 and the exhaust channel 200, so that the absorber 412 disposed in the first channel can be replaced.
[0035] The control assembly includes a controller and two detectors. The detectors are used to detect the concentration of volatile organic compounds (VOCs). The two detectors are respectively located within the intake channel 100 and the exhaust channel 200. The driver and both detectors are electrically connected to the controller. The detectors used to detect the concentration of VOCs are conventional components in the art and can be directly purchased commercially; their specific structure will not be described in detail here. The two detectors are referred to as intake detector 109 and exhaust detector 209. Intake detector 109 penetrates the side wall of intake channel 100, with its probe positioned within intake channel 100. Alternatively, intake detector 109 can be positioned entirely within intake channel 100. Exhaust detector 209 penetrates the side wall of exhaust channel 200, with its probe positioned within exhaust channel 200. Alternatively, exhaust detector 209 can be positioned entirely within exhaust channel 200.
[0036] The controller is configured to control the actuator to move the support frame 400 based on the volatile organic compound concentration signals acquired by the two detectors, thereby switching the support frame 400 between a first state and a second state. For example, the concentration signal acquired by the intake detector 109 is called the front-end concentration signal, and the concentration signal acquired by the exhaust detector 209 is called the rear-end concentration signal. The controller obtains the front-end concentration value based on the front-end concentration signal and the rear-end concentration value based on the rear-end concentration signal. It calculates the ratio of the rear-end concentration value to the front-end concentration value to obtain the residual ratio. When the residual ratio is not less than a preset threshold, it is determined that the absorption component 412 has reached saturation, and the controller controls the actuator to switch the state of the support frame 400. The preset threshold can be set to 70%, 90%, or other values. After the controller switches the state of the support frame 400, if the residual ratio is still not less than the preset threshold, it is determined that both absorption components 412 have reached saturation, and the switching of the support frame 400 state stops.
[0037] In operation, the controller determines whether the current absorption component 412 has reached saturation based on signals from the two detectors. When the current absorption component 412 reaches saturation, the controller drives the support frame 400 to move forward or backward, removing the current absorption component 412. The other absorption component 412 then moves between the intake channel 100 and the exhaust channel 200, allowing the purification device to continue operating. Operators only need to replace the removed absorption component 412 before it reaches saturation to keep the purification device running continuously, thus improving its operating rate.
[0038] In some embodiments of this utility model, the support frame 400 is provided with a first end plate 421 and a second end plate 422. The left ends of the two absorption channels 410 are flush with the first end plate 421, and the right ends of the two absorption channels 410 are flush with the second end plate 422. The first end plate 421 is provided with two first through holes, and the second end plate 422 is provided with two second through holes. The left ends of the two absorption channels 410 are connected to the inner edges of the two first through holes, and the right ends of the two absorption channels 410 are connected to the inner edges of the two second through holes. Thus, during the movement of the support frame 400, the first end plate 421 can cover the right end of the air intake channel 100, and the second end plate 422 can cover the left end of the second channel, which helps to prevent the gas in the exhaust channel 200 and the air intake channel 100 from flowing outside the volatile organic compound purification device.
[0039] In some embodiments of this utility model, a first sealing ring 120 is provided at the right end of the air intake channel 100, and a first end plate 421 abuts against the first sealing ring 120. A second sealing ring is provided at the left end of the exhaust channel 200, and a second end plate 422 abuts against the second sealing ring. Both the first sealing ring 120 and the second sealing ring are elastic material components, such as rubber material components. This can seal the gap between the first end plate 421 and the air intake channel 100, which helps to prevent the gas in the exhaust channel 200 and the air intake channel 100 from flowing outside the volatile organic compound purification device.
[0040] In some embodiments of this utility model, a detachable retaining ring 411 and a fixed retaining ring 413 are provided in the absorption channel 410. The absorption channel 410 is detachably connected to the detachable retaining ring 411, and the fixed retaining ring 413 is fixedly disposed in the absorption channel 410. The absorption component 412 is disposed between the detachable retaining ring 411 and the fixed retaining ring 413. Both the detachable retaining ring 411 and the fixed retaining ring 413 are coaxial with the absorption channel 410. The fixed retaining ring 413 is disposed on the left side of the absorption component 412, and the detachable retaining ring 411 is disposed on the right side of the absorption component 412 to fix the absorption component 412. When the absorption component 412 needs to be replaced, the detachable retaining ring 411 can be removed.
[0041] In some embodiments of this utility model, the removable retaining ring 411 is a snap ring. This structure is simple, and the removable retaining ring 411 is easy to assemble and disassemble.
[0042] In some embodiments of this utility model, the support frame 400 is provided with a sensing block 490, and the movement path of the sensing block 490 has a middle position. The control component includes a first indicator light 301, a proximity switch 130 for controlling the first indicator light 301 to turn on, and a manual switch 303 for controlling the first indicator light 301 to turn off. The proximity switch 130 is fixedly disposed relative to the air intake channel 100, and the sensing end of the proximity switch 130 faces the middle position. The movement path of the sensing block 490 also has a first end position and a second end position, and the middle position is located between the first end position and the second end position. That is, when the driver drives the support frame 400 to switch from the first state to the second state, or from the second state to the first state, the sensing block 490 will pass through the middle position, triggering the proximity switch 130 and turning on the first indicator light 301 to remind the operator to replace the absorption component 412. After the operator replaces the absorption component 412, they can operate the manual switch 303 to turn off the first indicator light 301.
[0043] The sensing block 490 can be located on the upper side between the two absorption channels 410. The proximity switch 130 can be a photoelectric switch that can be triggered without contact with the sensing block 490. The proximity switch 130 is located at the top of the right end of the air intake channel 100, and the sensing end of the proximity switch 130 faces to the right.
[0044] In some embodiments of this utility model, the control component includes a second indicator light 302. The controller is electrically connected to the second indicator light 302 and is configured to control the illumination of the second indicator light 302 based on the volatile organic compound concentration signals acquired by the two detectors. When the residual ratio is not less than a preset threshold, it is determined that the absorption component 412 has reached a saturated state, and the second indicator light 302 is controlled to be illuminated. Thus, the illumination of the second indicator light 302 can indicate whether the current absorption component 412 has reached a saturated state. When the first indicator light 301 is on and the second indicator light 302 is off, it indicates that the current absorption component 412 is not saturated, the removed absorption component 412 is saturated, the purification device is operating normally, and the staff can simply replace the removed absorption component 412. When both the first indicator light 301 and the second indicator light 302 are on, it indicates that both absorption components 412 are saturated, the purification device is essentially not working, and the staff needs to replace both absorption components 412.
[0045] In some embodiments of this invention, a filter screen 110 is provided at the left end of the air intake channel 100. This filters dust or other debris, preventing blockage of the absorption component 412.
[0046] In some embodiments of this utility model, the driver is a linear motor 304. The linear motor 304 extends forward and backward and is located at the bottom of the support frame 400, which makes the structure simple and the installation easy.
[0047] In some embodiments of this utility model, the absorption mechanism further includes a base 300, an exhaust channel 200 and an intake channel 100, all fixedly connected to the base 300, and the base 300 and the support frame 400 are slidably connected front and rear. The support frame 400 and the base 300 can be slidably connected via a guide rail slider mechanism. The main body of the linear motor 304 is fixedly mounted on the base 300, and the movable part of the linear motor 304 is connected to the support frame 400. This makes the front and rear movement of the support frame 400 more stable.
[0048] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments.
