A door pivots at the opening, and the inner wall of the door is sealed with cotton. However, even with this sealing mechanism, activated carbon adsorption towers still experience leakage during use, resulting in a poor door seal. Utility Model Content

[0024] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0026] like Figure 1-3 As shown, the utility model discloses an activated carbon adsorption tower box door sealing structure, including a box body 10, an activated carbon adsorption chamber 11 is provided in the box body 10, an air inlet 12, an exhaust port 13 and an opening 14 connected to the activated carbon adsorption chamber 11 are provided on the box body 10, the opening 14 is provided on the front side of the box body 10, a box door 20 is provided at the opening 14, one side of the box door 20 is rotatably connected to the box body 10, and the rotation axis of the box door 20 extends in the up and down direction. In the utility model, two openings 14 are provided side by side in the left and right directions, and each opening 14 corresponds to a box door 20.

[0027] The inner wall of the box door 20 is provided with a protrusion 21, and the circumferential side ring of the protrusion 21 is provided with an elastic annular sealing strip 22. The circumferential inner wall of the opening 14 is provided with an annular groove 15, and the annular groove 15 is adapted to the annular sealing strip 22. When the box door 20 is closed, the protrusion 21 extends into the opening 14, and the annular sealing strip 22 is tightly fitted and engaged in the annular groove 15.

[0028] The opening 14 is provided with a bevel 16 along its circumferential edge, and the bevel 16 extends obliquely from front to back toward the center line of the opening 14; by providing a plurality of annularly distributed bevels 16 on the circumferential side of the opening 14, the plurality of bevels 16 form a trumpet mouth, so that when the door 20 is closed, the guiding effect of the bevel 16 facilitates the annular sealing strip 22 to be stuck in the annular groove 15, making it easier to close the door 20.

[0029] A chamfer 17 is connected between the inclined surface 16 and the annular groove 15 . By providing the chamfer 17 , the chamfer 17 can guide the annular sealing strip 22 to smoothly transfer between the inclined surface 16 and the annular groove 15 , thereby making the door 20 open and close more smoothly.

[0030] The inclination angle β of the inclined surface 16 is 15 degrees to 30 degrees, preferably 20 degrees. By setting the inclined surface 16 with an inclination angle β of 15 degrees to 30 degrees, the annular sealing strip 22 can be easily inserted into the annular groove 15 when the door 20 is closed.

[0031] The distance h1 between the upper end of the inclined surface 16 and the protrusion 21 is greater than the distance h2 between the upper end of the annular sealing strip 22 and the protrusion 21. By setting the distance h1 between the upper end of the inclined surface 16 and the protrusion 21 to be greater than the distance h2 between the upper end of the annular sealing strip 22 and the protrusion 21, when the door 20 is closed, the annular sealing strip 22 is prevented from colliding with the outer edge of the front side of the opening 14, so that the door 20 can be closed smoothly.

[0032] The cross-sections of the annular sealing strip 22 and the annular groove 15 are both arc-shaped. By adopting the annular sealing strip 22 and the annular groove 15 with arc-shaped cross-sections, the annular sealing strip 22 and the annular groove 15 fit tightly when they are snapped together, and the sealing performance is good. At the same time, when the box door 20 is opened, the annular sealing strip 22 and the annular groove 15 are easy to separate.

[0033] The depth of the annular groove 15 is 4 mm to 5 mm.

[0034] The protrusion 21 is welded to the box door 20 .

[0035] The annular sealing strip 22 is formed of a silicone material; the silicone material makes the annular sealing strip 22 have the advantage of being resistant to high temperatures.

[0036] The inner wall of the box door 20 is provided with an annular sealing cotton 23, which surrounds the outside of the protrusion 21. When the box door 20 is closed, the annular sealing cotton 23 is tightly fitted with the front side wall of the box body 10. The annular sealing cotton 23 is high temperature resistant sealing cotton.

[0037] To sum up, the utility model provides a protrusion 21 on the inner wall of the box door 20, an elastic annular sealing strip 22 around the protrusion 21, and an annular groove 15 on the circumferential inner wall of the opening 14 of the box body 10. When the box door 20 is closed, the protrusion 21 extends into the opening 14, and the annular sealing strip 22 is tightly fitted and engaged in the annular groove 15. The sealing structure in which the annular sealing strip 22 is tightly fitted with the annular groove 15 can effectively prevent leakage, thereby making the sealing effect of the box door 20 better.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical practice of the present invention are still within the scope of the technical solution of the present invention.
