Description

Technical Field

[0001] The utility model relates to the field of waste gas filtration, in particular to a honeycomb activated carbon waste gas filtration mechanism. Background Art

[0002] The existing patent (publication number: CN211635881U) proposes a honeycomb activated carbon waste gas filtration mechanism, including a treatment cylinder. The two ends of the treatment cylinder are respectively communicated with an air inlet cylinder and an air outlet cylinder. One end of the air outlet cylinder far away from the treatment cylinder is communicated with a fan. Two filtration mechanisms are arranged inside the treatment cylinder. The two filtration mechanisms include orifice plate sleeves. When the waste gas is powered by the fan and enters the treatment cylinder under negative pressure and then enters the inside of the orifice plate sleeves, the unbalanced and unsaturated molecular attraction or chemical bond force existing on the surface of the activated carbon is utilized. However, for this device, "the two filtration mechanisms include orifice plate sleeves, and the surface of the orifice plate sleeves is fixedly connected with the inner wall of the treatment cylinder", the orifice plate sleeves are fixedly connected, and it is inconvenient to disassemble the orifice plate sleeves, which affects the convenience of replacing the activated carbon inside the orifice plate sleeves, and the waste gas filtration operation cannot be carried out during the replacement process of the activated carbon. Summary of the Invention

[0003] Aiming at the above deficiencies of the existing technology, the utility model provides a honeycomb activated carbon waste gas filtration mechanism. By reversely rotating the handle of the screw rod to drive the screw rod connecting block to descend, the sealing connecting blocks move away from each other until they are disengaged from the sealing connection grooves. At this time, the activated carbon switching block can be rotated 180° to make another sealing connection groove correspond to the sealing connecting block, so as to complete the switching of the old and new honeycomb activated carbon. At this time, the handle of the screw rod is rotated forward to drive the screw rod connecting block to rise until the sealing connecting block is inserted into the sealing connection groove, completing the replacement of the honeycomb activated carbon, enabling the device to conveniently replace the honeycomb activated carbon, and the normal waste gas filtration operation of the device will not be affected when disassembling the old honeycomb activated carbon and installing the new honeycomb activated carbon.

[0004] The purpose of the utility model is realized through the following technical solutions:

[0005] A honeycomb activated carbon waste gas filtering mechanism, comprising a pipeline bearing block, an activated carbon switching block, honeycomb activated carbon, a switching block positioning ring, a sealing connection block, a driving connecting rod, a driving screw, a screw connecting block, a rear sealing gasket, and a front sealing gasket. The activated carbon switching block has a switching block connection groove inside. The pipeline bearing block is rotatably connected to the switching block connection groove. The left and right sides of the pipeline bearing block have positioning ring connection blocks. The inner side of the positioning ring connection block 8 has a switching block positioning groove, which is adapted to the activated carbon switching block. The switching block positioning groove is connected to the activated carbon switching block, and the activated carbon switching block slides inside the switching block positioning groove. The middle part of the positioning ring connection block is fixedly connected to the switching block positioning ring. The switching block positioning ring is sleeved outside the activated carbon switching block. One side of the switching block positioning ring has a positioning piece, and the bottom of the positioning piece has a positioning block. The left and right sides of the activated carbon switching block have positioning grooves, which are adapted to the positioning blocks. The positioning grooves are connected to the positioning blocks, and the positioning blocks are inserted into the positioning grooves. Both end faces of the activated carbon switching block have two sealing connection grooves.

[0006] The two sealing connection grooves on the same end face are symmetrically arranged around the switching block connection groove. The sealing connection groove has an activated carbon connection groove inside. The honeycomb activated carbon is inserted into the activated carbon connection groove and fixed. The middle part of the pipeline bearing block has a pipeline bearing column. The end of the pipeline bearing column has an air delivery pipe. The top of the air delivery pipe has a gasket limiting platform. The middle part of the sealing connection block has a rear gasket connection platform, which is adapted to the air delivery pipe. The rear gasket connection platform is connected to the air delivery pipe.

[0007] The rear gasket connection platform is sleeved outside the air delivery pipe. The front part of the rear gasket connection platform is fixedly connected to the rear sealing gasket. The rear sealing gasket is pressed against the rear part of the gasket limiting platform. The sealing connection block is adapted to the sealing connection groove. The sealing connection block is connected to one of the two symmetric sealing connection grooves. The sealing connection block is inserted into the sealing connection groove.

[0008] Beneficial effects: 1. When the honeycomb activated carbon needs to be replaced after the honeycomb activated carbon waste gas filtering mechanism of the present utility model has been filtering waste gas for a long time, by reversely rotating the screw driving handle to lower the screw connecting block, the sealing connection blocks are separated from each other until they are disengaged from the sealing connection grooves. At this time, the activated carbon switching block can be rotated 180° so that another sealing connection groove corresponds to the sealing connection block, thereby completing the switching of the old and new honeycomb activated carbon. At this time, the screw driving handle is rotated forward to raise the screw connecting block until the sealing connection block is inserted into the sealing connection groove, completing the replacement of the honeycomb activated carbon. This enables the device to conveniently replace the honeycomb activated carbon, and the normal waste gas filtering operation of the device will not be affected when removing the old honeycomb activated carbon and installing the new honeycomb activated carbon.

[0009] 2. The front end of the sealing connection block of the present utility model is fixedly connected with a front sealing gasket, and the front end of the rear gasket connecting platform is fixedly connected with a rear sealing gasket, ensuring that when the sealing connection block is inserted into the sealing connection groove, the front sealing gasket is pressed tightly inside the sealing connection groove, and the rear sealing gasket is pressed tightly behind the gasket limiting platform, ensuring the sealing performance between the gas transmission pipe, the sealing connection block, and the activated carbon switching block connection body, and avoiding the leakage of waste gas during the filtering process.

[0010] 3. The positioning block of the present utility model is inserted into the positioning groove. When the activated carbon switching block rotates, the positioning block is ejected by the positioning groove. When the activated carbon switching block rotates 180°, the positioning block is reconnected with the positioning groove. The positioning block can position the activated carbon switching block, enabling the operator to accurately rotate the activated carbon switching block by 180°, eliminating the need for the operator to manually confirm the rotation angle, and further increasing the convenience of replacing the honeycomb activated carbon.

[0011] 4. A chamfer is provided at the opening of the sealing connection groove of the present utility model. During the connection process between the sealing connection block and the sealing connection groove, even if the sealing connection block and the sealing connection groove are not completely aligned, the chamfer can guide the sealing connection block to be correctly inserted into the sealing connection groove, preventing the sealing connection block and the sealing connection groove from being stuck due to slight misalignment during the connection process.
