[0031] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] This application provides a single-layer embedded heat-insulating sealing door and a bag filter, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of this application. And in the following embodiments, each embodiment is described with its own emphasis. For parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0033] Refer to Figure 1 , Figure 2 and Figure 3 , in an embodiment of the present application, the single-layer embedded heat-insulating sealing door includes: a door panel 1, which includes a top plate 11, a side plate 12 and a bottom plate 13; the top plate 11 includes a first extension part 111 that extends beyond the upper end of the side plate 12; a vertical doorframe plate 21, the top of which is used to support the first extension part 111; and a first seal 31, which includes a deformation part 311 and an installation part 312, the installation part 312 is fixed on the vertical doorframe plate 21, and the deformation part 311 is arranged between the first extension part 111 and the top of the vertical doorframe plate 21.

[0034] In this embodiment, the installation part 312 of the first seal 31 can be fixed on the vertical plate 21 of the door frame by a fixing member, and the deformation part 311 is located on the upper side of the top end of the vertical plate 21 of the door frame. When the door panel 1 is closed, the first extension part 111 presses the deformation part 311 against the top end of the vertical plate 21 of the door frame, thereby playing a sealing role.

[0035] Specifically, referring to Figure 3 , the first seal 31 is in the shape of a "9", and its deformation part 311 is annular.

[0036] Furthermore, the first seal 31 is integrally formed.

[0037] In this embodiment, the deformation part 311 of the first seal 31 can be formed by turning up the upper end of the first seal 31; since the deformation part 311 is annular and has a large elastic deformation space, the first seal 31 is not easily affected by thermal expansion and contraction, and the sealing performance is improved.

[0038] In this embodiment, optionally, a heat-insulating material 14 is provided inside the door panel 1; the heat-insulating material 14 can be but is not limited to heat-insulating aluminosilicate cotton.

[0039] Referring to Figure 2 , preferably, the bottom plate 13 includes a second extension part 131 that extends beyond the lower end of the side plate 12, and a second seal 32 is sleeved on the second extension part 131; the single-layer embedded heat-insulating sealed door further includes a horizontal plate 22 of the door frame for supporting the second extension part 131 of the bottom plate 13.

[0040] Optionally, the second seal 32 can be in a U shape and can be conveniently sleeved on the end of the second extension part 131.

[0041] Furthermore, a third seal 33 is provided between the side plate 12 and the vertical plate 21 of the door frame.

[0042] In this embodiment, by providing three seals, namely the first seal 31, the second seal 32, and the third seal 33, the sealing performance can be improved.

[0043] In this embodiment, optionally, a groove 121 for embedding the third seal 33 is provided on the outer side of the side plate 12.

[0044] In this embodiment, optionally, the materials of the first seal 31 and the third seal 33 can be silicone rubber; the material of the second seal 32 can be aluminosilicate cotton wrapped with canvas.

[0045] In some application scenarios, existing sealed doors are all rectangular, and the two silicone rubbers will deform and cannot be filled at the bending places, resulting in poor sealing of the sealing strips.

[0046] Based on this, in this embodiment, refer to Figure 4 , the corners of the door panel 1 are arc-shaped; this enables seamless sealing and reduces air leakage at the corners.

[0047] Correspondingly, an embodiment of the present application provides a bag filter, which includes a filtering chamber and a cleaning chamber; several single-layer embedded heat-insulating sealing doors as described above are provided on the cleaning chamber.

[0048] In summary, the 9-shaped silicone rubber structure size of the single-layer embedded heat-insulating sealing door of the present utility model is designed specifically, and is fixed with bolts and nuts, reducing the thermal expansion and contraction of the silicone rubber caused by temperature changes; the upper part of the sealing door can press the 9-shaped silicone rubber, and this 9-shaped silicone rubber is fixed with bolts and is not easy to fall off. It is sealed by three sealing strips. One is a 9-shaped sealing strip, the second is aluminosilicate cotton, and the third is a U-shaped customized silicone rubber. The tight design method and layout method of the sealing strips enhance the sealing performance; the corners of the sealing door are all arc-shaped, enabling seamless sealing and reducing air leakage at the corners.

[0049] Each device (components without specific structures described) selected in this application is a general standard component or a component known to those skilled in the art, and its structure and principle can be known by those skilled in the art through technical manuals or by conventional experimental methods.

[0050] In the description of the embodiments of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection.

[0051] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0052] Taking the above-mentioned ideal embodiment of the present utility model as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model.
