[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 As shown, the dichloromethane recovery and adsorption device described in the present invention includes a shell 1, a storage cover 2 and a connecting plate 3. A partition plate 13 is installed on one side of the inner wall of the shell 1, and a connecting cover 14 is rotatably installed inside the partition plate 13. Vents 15 are provided on both sides of the upper end of the inner wall of the connecting cover 14, and a rectangular array of slide rails 17 are installed on the outer wall of the upper end of the connecting cover 14. Connecting plates 3 are provided on both sides of the outer wall of the upper end of the connecting cover 14, and first sealing gaskets 32 are fixed to the outer walls of both sides of the upper end of the connecting plate 3. A baffle 33 is installed on the outer wall of one side of the connecting plate 3, and a storage cover 2 is plugged into the outer wall of one side of the shell 1. A driving mechanism 16 is provided on the upper end of the connecting cover 14.

[0032] When in use, the partition plate 13 divides the space inside the shell 1, and the gas inside the shell 1 flows inside the partition plate 13 through the vent hole 15. The connecting plate 3 can maintain a stable horizontal movement trajectory through the slide rail 17 and the slider 35. The connecting plate 3 can maintain a seal with the connecting cover 14 through the first sealing gasket 32, ensuring that the gas flowing out of the vent hole 15 completely enters the inside of the connecting plate 3 and is adsorbed and filtered by the filter element inside the connecting plate 3. The connecting plate 3 can maintain a seal with the storage cover 2 through the first sealing gasket 32, ensuring the storage The interior of the storage cover 2 is relatively sealed, and the baffle 33 can be controlled to block the vent 15 to ensure the controlled flow of gas inside the vent 15. The connecting plate 3 is stored inside the storage cover 2, so that the staff can disassemble or maintain the filter element body 31 located inside the storage cover 2. The driving mechanism 16 includes a driving motor and a driving shaft. The driving motor drives the driving shaft to rotate in a circle, so that the connecting cover 14 can rotate with the driving shaft, and the use positions of the two connecting plates 3 can be exchanged, so that the purpose of replacing the two filter element bodies 31 one by one can be achieved.

[0033] For airflow, for example, Figure 1 As shown, an exhaust pipe 11 is plugged and installed on the upper end of the outer wall of one side of the shell 1, and an air intake pipe 12 is plugged and installed on the lower end of the outer wall of one side of the shell 1. Both the exhaust pipe 11 and the air intake pipe 12 are connected to the interior of the shell 1.

[0034] During use, the gas is transported to the inside of the air inlet pipe 12 by an external power structure, and the gas flows into the lower end of the inner part of the shell 1 through the air inlet pipe 12 until the gas flows through the vent 15 to the upper end of the partition plate 13 and flows out through the exhaust pipe 11.

[0035] For filtering, for example, Figure 5 As shown, a filter element body 31 is placed inside the connecting plate 3, and the filter element body 31 and the connecting plate 3 are connected by bolts.

[0036] When in use, the filter element body 31 can adsorb and collect dichloromethane in the gas flowing inside the shell 1, thereby achieving the purpose of filtering the gas, and the filter element body 31 is kept firmly in the installation position inside the connecting plate 3 by bolts, ensuring that the filter element body 31 can be disassembled.

[0037] For sealing, for example, Figure 5 As shown, a second sealing gasket 34 is fixed to the outer wall of the lower end of the baffle 33 , and the second sealing gasket 34 is in contact with the outer wall of the upper end of the connecting cover 14 .

[0038] When in use, the second sealing gasket 34 ensures the sealing between the baffle 33 and the connecting cover 14 , so that the baffle 33 can cover the vent hole 15 through the second sealing gasket 34 .

[0039] In order to keep the moving track, for example, Figure 4 As shown, sliders 35 are installed on the outer walls of both sides of the baffle 33, and the sliders 35 are slidably installed inside the slide groove. A spring 18 is provided on one side of the inner wall of the slide groove, and the slider 35 is elastically connected to the inner wall of the slide groove through the spring 18.

[0040] During use, the spring 18 maintains the use position of the slider 35 relatively stable, and the slider 35 and the slide rail 17 ensure that the movement trajectory of the baffle 33 is stable and controlled.

[0041] In order to shield the storage cover 2, for example, Figure 3 As shown, a cover plate 21 is provided on the outer wall of the upper end of the storage cover 2 , and the size of the cover plate 21 is larger than the size of the upper end of the inner wall of the storage cover 2 .

[0042] When in use, the cover 21 can cover the open area at the upper end of the inner wall of the storage cover 2, ensuring the relative sealing of the interior of the storage cover 2 and the relative sealing of the interior of the outer shell 1, and the staff can remove the cover 21 by removing the screws of the cover 21 to ensure the controlled exposure of the interior of the storage cover 2.

[0043] In order to adjust the position of the connecting plate 3, for example, Figure 3 As shown, a push rod body 22 is provided on one side of the inner wall of the storage cover 2 , and an electromagnet 23 is provided on the outer wall of one end of the push rod body 22 , and the electromagnet 23 is in contact with the outer wall of the connecting plate 3 .

[0044] When in use, the external controller controls the operation of the electric push rod, and the push rod body 22 pushes the electromagnet 23 to move horizontally until the electromagnet 23 contacts the connecting plate 3. The magnetic force of the electromagnet 23 ensures the stability of the connection between the push rod body 22 and the connecting plate 3, so that when the push rod body 22 is reset, it can pull the connecting plate 3 to overcome the elastic force of the spring 18 and move.

[0045] When the present invention is in use, the gas is transported to the interior of the air inlet pipe 12 by the external power structure, and the gas flows into the lower end of the interior of the shell 1 through the air inlet pipe 12 until the gas flows through the vent 15 and flows to the upper end of the partition plate 13, and flows out through the exhaust pipe 11, ensuring that the flow trajectory of the gas is controlled and the flow is smooth. When the air flows through the filter element body 31, the activated carbon inside the filter element body 31 adsorbs and recovers the dichloromethane in the gas.

[0046] The driving mechanism 16 drives the connecting cover 14 to rotate in a circular motion through the driving motor and the driving shaft, thereby exchanging the use positions of the two filter element bodies 31 and rotating the filter element to be replaced to the side of the storage cover 2;

[0047] The staff controls the operation of the electric push rod through an external controller, and the push rod body 22 pushes the electromagnet 23 to move horizontally until the electromagnet 23 contacts the connecting plate 3. The magnetic force of the electromagnet 23 ensures the stability of the connection between the push rod body 22 and the connecting plate 3. When the push rod body 22 is reset, it can pull the connecting plate 3 to overcome the elastic force of the spring 18 and move until the connecting plate 3 moves into the storage cover 2.

[0048] When the connecting plate 3 is separated from the upper end of the vent hole 15, the baffle 33 blocks the vent hole 15 through the second sealing gasket 34 to prevent the gas from continuing to flow, thereby ensuring the controlled flow of gas inside the vent hole 15. When the vent hole 15 on one side is blocked, the vent hole 15 on the other end is connected, so that the device can continue to filter the gas while the filter element body 31 is replaced.

[0049] The connecting plate 3 maintains sealing with the inner wall of the storage cover 2 through the first sealing gasket 32, thereby shielding the storage cover 2 and preventing the gas inside the housing 1 from entering the storage cover 2;

[0050] The staff manually opens the locking screws on the upper end of the cover 21, so that the cover 21 can be removed. The cover 21 can cover the upper end surface of the storage cover 2 to ensure that the interior of the storage cover 2 is exposed under control. After the residual gas inside the storage cover 2 escapes, the staff reaches into the storage cover 2 to remove and replace the filter element body 31 in the connecting plate 3 moved to the inside of the storage cover 2.

[0051] It should be noted that the present invention is a dichloromethane recovery adsorption device. The components in the present invention are all components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

The above embodiments and descriptions are merely illustrative of the principles of the present invention.
