Description

Technical Field

[0001] This utility model relates to the field of hazardous gas treatment technology, specifically a hazardous gas collection device for hazardous waste treatment. Background Technology

[0002] When hazardous waste is disposed of, the direct emission of harmful gases can cause air pollution. Therefore, harmful gases are usually collected before treatment. Existing harmful gas collection devices, such as the harmful gas collection device with a filter structure for plastic production proposed in the patent document with announcement number CN217746385U, collect harmful gases directly through a collection tank by pressurizing the collection tank to achieve collection.

[0003] Although the collection tank can conveniently collect harmful gases, it cannot be emptied properly when the harmful gases are discharged, resulting in residual harmful gases in the collection tank. Therefore, a new hazardous waste treatment hazardous gas collection device is proposed to optimize the existing technology. Utility Model Content

A closing valve 13 is fixedly installed on the branch pipe 11.

[0026] The collection tank 4 is connected to the external threaded connector 12 via the gas tank connector 5. The air pump 2 draws in harmful gases through the collection pipe 9, and then outputs the drawn harmful gases through the output pipe 10. The harmful gases are then transported to the corresponding collection tank 4 through the branch pipe 11 for collection. When the collection tank 4 is filled with gas, the baffle 8 is pressed against the tail end of the collection tank 4 to form a collection chamber for storing harmful gases. When it is necessary to vent the gas, the baffle 8 can be pushed to the front end of the collection tank 4 when the gas is about to be vented, so that the harmful gases in the collection tank 4 are vented and the harmful gases are not left in the collection tank 4.

[0027] The placement platform 3 is provided with two placement slots 14, each containing a collection tank 4, and a branch pipe 11 is provided for each collection tank 4.

[0028] Two placement slots 14 are provided so that two collection tanks 4 can be placed respectively. With the opening and closing of the closing valve 13, the two branch pipes 11 can be switched so that the collection tank 4 can be switched when it is full, thus making it convenient to replace the full collection tank 4.

[0029] A return pipe 15 is fixedly connected to the side of the tail end of the output pipe 10. The return pipe 15 is connected to the collection pipe 9. A pressure relief mechanism 16 is provided at the tail end of the output pipe 10.

[0030] The pressure relief mechanism 16 includes a drive threaded rod 17, a first plate-shaped movable seat 18, a second plate-shaped movable seat 19, a spring 20, a sealing plug 21, and a plug seat 22.

[0031] The first plate-shaped movable seat 18 and the second plate-shaped movable seat 19 are both slidably connected to the inner side of the output tube 10. The inner wall of the output tube 10 is provided with a sliding groove 23 for the edges of the first plate-shaped movable seat 18 and the second plate-shaped movable seat 19 to be inserted and slid. The drive threaded rod 17 is threadedly connected to the first plate-shaped movable seat 18. The first plate-shaped movable seat 18 is provided with a threaded hole for the drive threaded rod 17 to pass through and be threadedly connected. The drive threaded rod 17 is rotatably connected to the end of the output tube 10. The spring 20 is provided in the opposite side grooves of the first plate-shaped movable seat 18 and the second plate-shaped movable seat 19. The sealing plug 21 is fixedly connected to the bottom surface of the second plate-shaped movable seat 19. The plug seat 22 is fixedly connected to the inner wall of the output tube 10. The plug seat 22 corresponds to and is adapted to the sealing plug 21.

[0032] A worm gear 24 is fixedly connected to one end of the drive threaded rod 17. A worm 25 is provided on the outer side of the worm gear 24 to mesh with it.

The output end of the motor 6 is fixedly connected to the worm 25.

[0033] The first plate-shaped movable seat 18 provides elastic pressure support to the second plate-shaped movable seat 19 through the spring 20, so that the sealing plug 21 abuts against the plug seat 22, thereby forming a pressure seal. When the air pump 2 inflates the collection tank 4 through the output pipe 10 and the branch pipe 11 beyond the elastic pressure, the pressure can be relieved by the pressure relief mechanism 16 to avoid excessive collection and the danger of excessive pressure.

[0034] When the output pipe 10 is depressurized by the depressurization mechanism 16, the released harmful gas can be returned to the collection pipe 9 through the return pipe 15 to prevent the harmful gas from leaking out.

[0035] The worm gear 25 is driven by the motor 6, which in turn drives the threaded rod 17 to rotate through the worm gear 24. This drives the first plate-shaped movable seat 18 to slide along the sliding groove 23, thereby controlling the maximum gap between the first plate-shaped movable seat 18 and the second plate-shaped movable seat 19. This controls the elastic pressure applied by the spring 20 to the second plate-shaped movable seat 19, and controls the opening pressure between the sealing plug 21 and the plug seat 22.

[0036] Both motor 6 and air pump 2 are externally connected to a power source and a switch.

[0037] The working principle of this utility model is as follows:

[0038] In use, the motor 6 drives the worm gear 25, which in turn drives the threaded rod 17 to rotate through the worm gear 24. This, in turn, drives the first plate-shaped movable seat 18 to slide along the sliding groove 23, thereby controlling the maximum gap between the first plate-shaped movable seat 18 and the second plate-shaped movable seat 19. This controls the elastic pressure applied by the spring 20 to the second plate-shaped movable seat 19, and controls the opening pressure between the sealing plug 21 and the plug seat 22. At this time, a collection tank 4 is placed in each of the placement slots 14 on the placement platform 3. The gas tank connector 5 on the head of the collection tank 4 is connected to the external threaded connector 12, so that the collection tank 4 is connected to the branch pipe 11. At this time, the closing valve 13 on one of the branch pipes 11 is opened, allowing... Branch pipe 11 is connected to collection tank 4. At this time, harmful gas can be drawn in through collection pipe 9 by air pump 2, and then output through output pipe 10. The harmful gas is then transported to the corresponding collection tank 4 through branch pipe 11 for collection. When the collection tank 4 is filled with air, the baffle 8 is pressed against the tail end of the collection tank 4 to form a collection chamber for storing harmful gas. When the pressure gauge on the collection tank 4 reaches the set rated pressure, the corresponding closed valve 13 is closed and another closed valve 13 is opened. Harmful gas can be collected through another collection tank 4. At this time, the full collection tank 4 is disassembled and replaced with a new collection tank 4 to carry out continuous collection operation in a cycle.
