[0048] Example 6

[0049] In this embodiment, Figure 1-7 As shown, S1: input the gas into the interior of the air inlet tank 21, and perform the first step of filtering on it. First, the gas enters the interior of the air inlet tank 21 through the air inlet pipe 9, and the gas passes through the interior of the activated carbon plate 22 and the molecular sieve 23 to adsorb the toxic substances inside;

[0050] S2: Spraying water on the incoming gas. After the gas enters the interior of the conical tube 15, the second liquid pump 42 is turned on to allow the water in the water tank 41 to enter the interior of the water inlet pipe 46 through the water pumping pipe 43. Then, the incoming gas is sprayed through the water inlet pipe 46 using the spraying pipe 45, so that the dropped particulate impurities enter the interior of the disassembly pipe 31.

[0051] S3: The sprayed water is made to reflux. While spraying the water, the first pump 33 is turned on to pump the water in the disassembly pipe 31 into the water tank 41 for reuse.

[0052] S4: The treated gas is discharged into the interior of the purification box 61 for purification. While the gas is sprayed with water, the vacuum pump 64 is turned on to pump the internal gas into the interior of the purification box 61. A liquid medicine for purifying the gas is placed inside the purification box 61 so that the incoming gas can directly enter the interior of the liquid medicine, so that the gas can be discharged after being purified. Finally, the valve 12 is opened to discharge the liquid medicine through the drain pipe 11.

[0053] It should be noted that, in this embodiment, when a rubber additive is used to produce a harmful gas purification device, Figure 1-7 As shown, the harmful gas during the production of rubber additives enters the interior of the air inlet tank 21 through the air inlet pipe 9, and when it moves downward through the molecular sieve 23 and the activated carbon plate 22, the toxic substances in the harmful gas can be easily adsorbed, and then enters the interior of the conical tube 15. When the gas enters the interior of the conical tube 15, the second liquid pump 42 is turned on to conveniently pump the interior of the water tank 41, and the spray pipe 45 is used to spray the incoming gas, so that the particulate impurities in the gas are sprinkled and fall on the filter 16. The sprayed water enters the interior of the conical tube 15 and enters the interior of the disassembly tube 31. Then, the first liquid pump 33 is turned on to conveniently pump the internal water into the interior of the water tank 41, so as to facilitate the reuse of the water source. At the same time, turn on the vacuum pump 64 to allow the gas in the conical tube 15 to be sucked into the interior of the purification box 61, so that the gas can completely enter the interior of the medicinal liquid in the purification box 61. After the continuous entry of the gas, the purified gas can be discharged through the exhaust pipe 65. After the gas purification is completed, open the valve 12 to discharge the medicinal liquid in the purification box 61. Then, turn the handle 10 to easily rotate and disassemble the disassembly tube 31. At this time, the connecting tube 34 can prevent the position of the connecting tube 34 from remaining unchanged under the action of the limit plate 54, and prevent the rotation of the reflux pipe 32, causing it to be entangled. After disassembling the disassembly tube 31, pulling the push-pull rod 13 can easily take out the filter 16 for easy cleaning.

A harmful gas purification device for rubber additive production according to claim 4, Features: The limiting mechanism (5) comprises a first support seat (51), a second support seat (52), a limiting groove (53) and a limiting plate (54); the first support seat (51) and the second support seat (52) are fixedly mounted on the bottom of the support seat (1); the limiting groove (53) is arranged inside the left side wall of the first support seat (51); the limiting plate (54) is fixedly mounted on the right side wall of the connecting tube (34); the right end of the limiting plate (54) is slidably connected to the inside of the limiting groove (53); and handles (10) are fixedly mounted on both side walls of the disassembly tube (31).

6. A harmful gas purification device for rubber additive production according to claim 2, Features: A liquid discharge pipe (11) is fixedly mounted on the right end side wall of the purification box (61), and a valve (12) is fixedly mounted inside the liquid discharge pipe (11).

7. A harmful gas purification device for rubber additive production according to claim 4, Features: A filter screen (16) is placed at the bottom of the disassembly tube (31), and the diameter of the filter screen (16) matches the diameter of the disassembly tube (31). A lifting rod (13) is symmetrically fixedly installed on the top of the filter screen (16), and the top surface of the lifting rod (13) is higher than the top surface of the disassembly tube (31).

8. A harmful gas purification device for rubber additive production according to claim 4, Features: A sealing gasket (14) is fixedly mounted on the bottom surface of the disassembly tube (31).

9. A method for using a harmful gas purification device for rubber additive production according to any one of claims 1 to 8, Features: Here are the steps: S1: The gas is input into the interior of the gas inlet tank (21) and filtered in the first step. First, the gas enters the interior of the gas inlet tank (21) through the gas inlet pipe (9), and the gas passes through the interior of the activated carbon plate (22) and the molecular sieve (23) to adsorb the toxic substances inside; S2: spraying water on the incoming gas. After the gas enters the interior of the conical tube (15), the second liquid pump (42) is turned on to allow the water in the water tank (41) to enter the interior of the water inlet pipe (46) through the water pumping pipe (43). Then, the incoming gas is sprayed through the water inlet pipe (46) using the spraying pipe (45), so that the dropped particulate impurities enter the interior of the disassembly pipe (31); S3: The sprayed water is made to reflux. While the water is being sprayed, the first pumping pump (33) is turned on to pump the water in the disassembly pipe (31) into the water tank (41) for reuse; S4: The treated gas is discharged into the interior of the purification box (61) for purification. While the gas is sprayed with water, the vacuum pump (64) is turned on to pump the internal gas into the interior of the purification box (61). A liquid medicine for purifying the gas is placed inside the purification box (61) so that the incoming gas can directly enter the interior of the liquid medicine, so that the gas can be purified and then discharged. Finally, the valve (12) is opened to discharge the liquid medicine through the discharge pipe (11).
