[0002] Solution tank is an important liquid storage equipment, which is widely used in petroleum, chemical, medicine and other industrial fields. However, when the solution tank is affected by the environment or improper human operation, it is easy to cause the pressure inside the tank to decrease and form negative pressure. In order to avoid this situation, it is necessary to ensure that the solution tank has a certain air permeability. However, the liquid stored in the solution tank will emit various gases that are harmful to the human body, which need to be treated by filtering devices such as activated carbon. However, the existing filtering devices are large in size and cannot be matched and connected with the solution tank, so they are not suitable for solution tanks. Therefore, it is necessary to propose an activated carbon adsorption ventilation device. Utility Model Content

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Please combine Figures 1 to 4 The activated carbon adsorption ventilation device includes a cylinder 1 in which activated carbon 3 is stored. Connecting flanges 2 are provided on the top and bottom of the cylinder 1 so that the cylinder 1 can be connected to a solution tank and other pipelines. A leak-proof structure is provided inside the cylinder 1 to prevent leakage of the activated carbon 3. A detachable sealing cover 5 is provided at the outlet end of the cylinder 1 to facilitate replacement of the activated carbon 3 in the cylinder 1. The sealing cover 5 is a flange cover, which can be fixed to the cylinder 1 by bolts, and a flange cover is also provided at the other end of the cylinder 1. After opening it, the rubber block 6 can be taken out, and in order to facilitate the removal of the filter cylinder 4, a handle 15 is also provided on the sealing cover 5.

[0026] The anti-leakage structure is a filter cylinder 4, which is slidably connected to the cylinder body 1, and the activated carbon 3 is in the filter cylinder 4. The filter cylinder 4 is provided with a material replacement port 11.

[0027] Through the above technical solution, by designing the leak-proof structure into a filter cylinder 4, it is possible to ensure that the activated carbon 3 will not leak while making the replacement of the activated carbon 3 more convenient. The saturated activated carbon 3 in the cylinder 1 can be conveniently taken out, and then the activated carbon 3 can be conveniently delivered into the cylinder 1.

[0028] A rubber block 6 is provided inside the cylinder 1 to limit sliding. A groove 7 is provided at one end of the rubber block 6 that contacts the filter cylinder 4 . A protrusion 8 is provided at one end of the filter cylinder 4 . The protrusion 8 extends into the groove 7 and engages with the groove 7 .

[0029] Through the above technical solution, by arranging a rubber block 6 in the cylinder 1, a slot 7 and a protrusion 8 are respectively arranged on the rubber block 6 and the filter cylinder 4, so that when the filter cylinder 4 is taken out to replace the activated carbon 3, the through hole leading to the outside can be automatically blocked to prevent harmful gases from escaping when the activated carbon 3 is replaced.

[0030] The cylinder 1 is provided with an expansion groove at the position of the rubber block 6. A limit ring 9 is provided on the rubber block 6. The limit ring 9 extends into the expansion groove and is slidably connected with the inner wall of the expansion groove.

[0031] Through the above technical solution, the expansion groove makes the inner diameter of the area of ​​the cylinder 1 where the rubber block 6 is set larger, so that the limit ring 9 can be cooperated with to realize the movement limitation of the rubber block 6, so that the rubber block 6 cannot continue to move with the filter cylinder 4 after blocking the vent hole, and also provides conditions for the rubber block 6 to separate from the filter cylinder 4.

[0032] The slot 7 is a spherical slot, the protrusion 8 is matched with the slot 7, and the opening of the slot 7 is an expansion structure.

[0033] Through the above technical solution, since the rubber block 6 is made of flexible material, the rubber block 6 can move with the protrusion 8 without limit, and when restricted, the protrusion 8 will be detached from the slot 7. The expansion structure of the opening of the slot 7 makes it easier for the protrusion 8 to be inserted into the slot 7.

[0034] An air hole 10 is provided at one end of the cylinder 1 close to the rubber block 6 .

[0035] Through the above technical solution, the air holes 10 prevent the rubber block 6 from being affected by air pressure and negative pressure and being unable to move normally when moving.

[0036] A shaft 12 is rotatably mounted on the sealing cover 5, one end of the shaft 12 is fixedly connected to one end of the filter cylinder 4, and a torsion wheel 13 is provided at the other end of the shaft 12. Blocking pieces 14 are provided on both sides of the filter cylinder 4, and the two blocking pieces 14 are on the same center line with the two connecting flanges 2.

[0037] Through the above technical solution, by arranging two plugging pieces 14 on the filter cylinder 4 and arranging an axis rod 12 connected to the filter cylinder 4 on the sealing cover 5, the filter cylinder 4 can be rotated from the outside, so that the activated carbon adsorption ventilation device can be switched between the ventilation mode and the closed mode as needed, thereby improving the applicability of the activated carbon adsorption ventilation device.

[0038] The cylinder 1, the connecting flange 2, the sealing cover 5 and the leak-proof structure are all made of stainless steel.

[0039] Through the above technical solution, the use of stainless steel makes the activated carbon adsorption ventilation device more durable and less prone to aging and other problems.

[0040] The implementation principle of an activated carbon adsorption ventilation device in the embodiment of the present application is:

[0041] When in use, the connecting flange 2 at the bottom of the cylinder 1 is connected to the vent flange at the top of the solution tank by screws, thereby ensuring the normal ventilation of the solution tank and avoiding negative pressure in the solution tank, and at the same time, the harmful substances in the solution tank can be adsorbed by the activated carbon 3 before being discharged, thereby preventing the harmful substances from escaping;

[0042] When the activated carbon 3 in the cylinder 1 is saturated and needs to be replaced, the sealing cover 5 is opened, and then the filter cylinder 4 is pulled out from the cylinder 1. During the process of being pulled out, the filter cylinder 4 will drive the rubber block 6 to move through the protrusion 8 until the rubber block 6 blocks the through hole of the cylinder 1 connecting the two connecting flanges 2. At this time, the limit ring 9 on the rubber block 6 is restricted by the expansion groove, so that it cannot be separated from the cylinder 1, so that the protrusion 8 on the filter cylinder 4 is separated from the slot 7. When the filter cylinder 4 is pulled out, the saturated activated carbon 3 is poured out through the material replacement port 11 and then replaced with new activated carbon 3. Then, the filter cylinder 4 with the replaced activated carbon 3 is inserted into the cylinder 1. During this process, the rubber block 6 is pushed back to its original position until the protrusion 8 is stuck in the slot 7 again, thereby completing the replacement of the activated carbon 3.

[0043] When the solution tank needs to be closed for ventilation, the shaft 12 and the filter cylinder 4 are driven to rotate by the twist wheel 13, so that the filter cylinder 4 rotates ninety degrees, so that the two plugging pieces 14 block the through holes of the cylinder body 1 connecting the two connecting flanges 2.

[0044] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
