Description

Technical Field

[0001] The utility model relates to the technical field of gas processing, in particular to a hot-pressed gas processing device. Background Art

[0002] In the process of producing particleboard, in order to ensure that the board does not warp after forming, it is necessary to control the moisture content of each layer during the lamination process before the finished product is cured, especially the moisture content of the wood chips used in the upper and lower surface layers and the board material after pressing to keep consistent, so as to ultimately ensure that the finished particleboard does not warp. However, particleboard materials are composed of sawdust and a large amount of adhesive, and the moisture mainly comes from the liquid adhesive. When using a hot press to heat and pressurize the particleboard blank, the evaporated gas may contain sawdust and harmful gases. Therefore, it is necessary to treat the gas generated in the hot pressing process of particleboard.

[0003] For example, the Chinese patent with patent number 201920723197.X discloses a new type of plate hot pressing gas purification treatment device, including a hot press, the hot press is provided with a pressing plate, and exhaust plates are arranged around the pressing plate. The exhaust plate is connected to an annular air pipe, and a filter joint is arranged on the annular air pipe. The filter joint is connected to the pipeline, and the other end of the pipeline is connected to an activated carbon box. Activated carbon particles are arranged inside the activated carbon box. The activated carbon box is connected to an exhaust pump through a short tube, and an exhaust port is arranged on the top of the exhaust pump.

[0004] The existing hot-pressed gas processing device filters dust by setting a filter joint. In the actual filtering process, since dust is easy to adhere to the filter joint and cause clogging of the filter joint, it is necessary to clean the filter joint regularly. When cleaning and maintaining the filter joint, the existing technology needs to remove the filter joint from the annular air pipe, which is inconvenient to clean and reduces the convenience of using the device.

[0031] In the above embodiment, by starting the vacuum pump 103, the dust and harmful gases generated in the hot press can enter the filter barrel 10 through the air inlet pipe 101, and then enter the exhaust pipe 102 through the dust filter screen 201. At this time, the dust filter screen 201 can filter the dust. When the dust filter screen 201 needs to be cleaned, the gear 204 is driven to rotate by starting the motor 205. The gear 204 rotates and meshes with the outer gear ring 203 to drive the outer gear ring 203 to rotate. The outer gear ring 203 rotates to drive the cleaning brush rod 202 Rotate around the dust filter screen cover 201 to brush off the dust attached to the sides and bottom of the dust filter screen cover 201, thereby avoiding clogging of the dust filter screen cover 201.

[0034] In the above embodiment, by starting the vacuum pump 103, the vacuum pump 103 can make the dust and harmful gases generated in the hot press enter the filter barrel 10 through the air inlet pipe 101, and then enter the exhaust pipe 102 through the dust filter screen 201. The dust filter screen 201 filters the dust, and the harmful gases enter the baffle channel 305 through the exhaust pipe 102 and flow in the baffle channel 305. At this time, the multiple groups of activated carbon plates 302 in the baffle channel 305 can filter and purify the harmful gases. By filtering and purifying the dust and harmful gases generated in the hot pressing working link in turn, the treatment effect of the device on the hot pressing gas is improved. In addition, by setting the baffle channel 305, the time for harmful gases to flow through the filter box 303 can be extended without increasing the volume of the device, thereby increasing the time for filtering and purifying harmful gases, and further improving the effect of the device on filtering and purifying harmful gases. The cover plate 306 is detachable, which is convenient for cleaning and replacing the components in the installation cavity after removing the cover plate 306.

[0035] On the basis of the above embodiment, further, the second filter assembly 30 also includes two groups of positioning rods 301; two groups of positioning grooves 3041 are correspondingly opened at the top of the multiple groups of baffles 304, and the two groups of positioning rods 301 can be clamped in the positioning grooves 3041 on the multiple groups of baffles 304, and the multiple groups of activated carbon plates 302 are arranged at intervals at the bottom of the two groups of positioning rods 301. In the above embodiment, the positioning rods 301 and the multiple groups of baffles 304 are clamped and connected, and the multiple groups of activated carbon plates 302 can be installed and removed by installing and removing the positioning rods 301, which is convenient for installing and removing the activated carbon plates 302, and convenient for replacing the activated carbon plates 302.

[0036] Please also read Figure 5On the basis of the above embodiment, further, both ends of the cover plate 306 are hinged with the limit plates 307 through the torsion springs 308, and the two sets of limit plates 307 are provided with fixed hooks 3071, and both ends of the filter box 303 are provided with hook grooves, and the limit plates 307 can rotate to make the fixed hooks 3071 hooked in the hook grooves or separated from the hook grooves. Multiple sets of anti-slip buckle grooves 3072 are provided at intervals on the two sets of limit plates 307.

[0037] In the above embodiment, the two groups of limit plates 307 are rotated to separate the fixing hooks 3071 from the hook grooves. At this time, the torsion spring 308 is twisted, and the cover plate 306 can be removed from the filter box 303 to open the installation cavity. By covering the cover plate 306 on the filter box 303 and sealing and blocking the installation cavity, and then canceling the force applied to the two groups of limit plates 307, the reaction force of the torsion spring 308 can cause the two groups of limit plates 307 to rotate in the opposite direction. The two groups of limit plates 307 rotate in the opposite direction to cause the two groups of fixing hooks 3071 to be hooked in the two groups of hook grooves to fix the cover plate 306.

[0038] The specific implementation of the hot pressurized gas processing device is as follows:

[0039] By starting the vacuum pump 103, the vacuum pump 103 can make the dust and harmful gases generated in the hot press enter the filter barrel 10 through the air inlet pipe 101, and then enter the exhaust pipe 102 through the dust filter screen 201. The dust filter screen 201 filters the dust, and the harmful gases enter the baffle channel 305 through the exhaust pipe 102 and flow in the baffle channel 305. When it is necessary to clean the dust attached to the dust filter screen 201, the gear 204 is driven to rotate by starting the motor 205. The gear 204 rotates and meshes with the outer gear ring 203 to drive the outer gear ring 203 to rotate. The rotation of the outer gear ring 203 can drive the cleaning brush rod 202 to rotate around the dust filter screen cover 201, thereby brushing off the dust attached to the sides and bottom of the dust filter screen cover 201, thereby avoiding the clogging of the dust filter screen cover 201. The dust filter screen cover 201 can be cleaned without disassembling the dust filter screen cover 201. The dust filter screen cover 201 is convenient to clean, and the convenience of using the device is improved. The dust brushed off from the dust filter screen cover 201 can fall and accumulate on the conical slag discharge port 104. The dust can be discharged from the filter barrel 10 by opening the valve on the conical slag discharge port 104, and the dust can be conveniently removed.

[0040] At the same time, when the harmful gas flows in the baffle channel 305, the multiple groups of activated carbon plates 302 in the baffle channel 305 can filter and purify the harmful gas, and the filtered and purified harmful gas is discharged through the vacuum fan 103. The dust and harmful gas generated in the hot pressing working link are filtered and purified in turn, thereby improving the treatment effect of the device on the hot pressed gas. In addition, by setting the baffle channel 305, the time for the harmful gas to flow through the filter box 303 can be extended without increasing the volume of the device, thereby increasing the time for filtering and purifying the harmful gas, and further improving the effect of the device in filtering and purifying the harmful gas.
