Description

Technical Field

[0001] This utility model relates to the field of rotary dehumidifier sealing technology, and in particular to a rotary dehumidifier housing sealing structure. Background Technology

[0002] Rotary dehumidifier units are a special type of combined air conditioning, mainly providing a stable low-humidity environment for manufacturing workshops. They are widely used in industries such as food, pharmaceuticals, bridges, military, aerospace, and lithium batteries. The sealing structure of the rotary dehumidifier's casing is related to its dehumidification performance and energy consumption. The better the sealing effect, the less air leaks in or out, the lower the dehumidification energy consumption, and the smaller the dehumidification performance degradation. Existing air conditioning casing structures usually use interlocking between plates, with the plates and sealant (6) gaskets pressed together, edge strips for edging, and a large number of screws drilled for fixing, or clamping through buckle devices. This type of structure is prone to loosening of screws, buckle loosening, sealing failure, and weakening of casing strength during long-term use due to pressure and vibration. Utility Model Content

[0027] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0028] Please refer to Figures 1 to 4 , Figure 8 and Figure 9 As shown, the present invention discloses a sealing structure for a rotary dehumidifier housing, comprising a first splicing plate 1, a second splicing plate 2, and a sealing element 3; the first splicing plate 1 has a first sealing groove 11 on its edge, the second splicing plate 2 has a first protrusion 21 adapted to the first sealing groove 11, and the sealing element 3 has a first sealing part that fits against the first protrusion 21.

[0029] Working principle: First protrusions 21 and first sealing grooves 11 are added to the first splicing plate 1 and the second splicing plate 2 respectively to resist vibration. At the same time, the sealing element 3 is used to seal the gap at the splicing point of the first splicing plate 1 and the second splicing plate 2 to ensure the sealing of the splicing point.

[0030] It is worth noting that, please refer to Figure 3 and Figure 4 As shown, the cross-section of the first protrusion 21 can be T-shaped or L-shaped. By inserting the first protrusion 21 of this shape into the corresponding first sealing groove 11, it can resist vertical and horizontal vibrations, thereby ensuring the splicing effect between the first splicing plate 1 and the second splicing plate 2.

[0031] The cross-section of the first protrusion 21 can also be elongated. In one embodiment, please refer to... Figure 1As shown, a second sealing groove 4 is provided on the surface of the second splicing plate 2, and the opening direction of the second sealing groove 4 is perpendicular to the opening direction of the first sealing groove 11; a second protrusion 5 adapted to the second sealing groove 4 is provided on the first splicing plate 1, and the sealing member 3 has a second sealing part that fits with the second protrusion 5. The insertion of the second protrusion 5 into the second sealing groove 4 is added to resist vertical and lateral vibrations.

[0032] In another embodiment, a second protrusion 5 is provided on the surface of the second splicing plate 2, and the extending direction of the second protrusion 5 is perpendicular to the extending direction of the first protrusion 21; a second sealing groove 4 adapted to the second protrusion 5 is provided on the first splicing plate 1, and the sealing member 3 has a second sealing part that fits with the second protrusion 5. The insertion of the second protrusion 5 into the second sealing groove 4 is added to resist vertical and lateral vibrations.

[0033] In some implementations, please refer to Figure 1 , Figure 3 ,and Figure 4 As shown, sealant 6 is applied to the joint between the first splicing plate 1 and the second splicing plate 2. The sealant 6 further improves the sealing performance at the joint between the first splicing plate 1 and the second splicing plate 2. The sealant 6 may be polyurethane weather-resistant adhesive, neutral silicone weather-resistant adhesive, etc.

[0034] In some implementations, please refer to Figure 1 and Figure 2 As shown, the sealing element 3 includes a first sealing strip 31, a second sealing strip 32, and a third sealing strip 33. A mounting space 7 is formed between the first splicing plate 1 and the second splicing plate 2. The second sealing strip 32 is disposed within the mounting space 7, and is positioned between the first sealing strip 31 and the third sealing strip 33. The first sealing strip 31, the second sealing strip 32, and the third sealing strip 33 work together to seal the gap between the first splicing plate 1 and the second splicing plate 2. Preferably, the thickness of the first sealing strip 31 and the third sealing strip 33 is 8mm to 10mm, and the thickness of the second sealing strip 32 is 10mm to 15mm.

[0035] It is worth noting that if the second protrusion 5 is present, the third sealing strip 33 also needs to be sealed between the second protrusion 5 and the second sealing groove 4.

[0036] In some implementations, please refer to Figure 5 As shown, the cross-sectional area of ​​the second sealing strip 32 is larger than the cross-sectional area of ​​the placement space 7. Limiting the cross-sectional area of ​​the second sealing strip 32 allows the elastic force generated by the compression of the second sealing strip 32 after assembly to act on the first splicing plate 1 and the second splicing plate 2, thereby compressing the first sealing strip 31 and the third sealing strip 33, thus achieving self-sealing after assembly. Figure 5 As shown, the area filled with diagonal lines represents the compressed area 8 of the first sealing strip 31 and the third sealing strip 33. Preferably, the cross-section of the second sealing strip 32 is rectangular or circular.

[0037] In order to effectively compress the first sealing strip 31 and the third sealing strip 33, taking the second sealing strip 32, which has a rectangular cross-section and is made of hard rubber, as an example, the cross-sectional dimensions of the second sealing strip 32 in its free state are 10mm to 15mm. When the second sealing strip 32 is not installed, the cross-sectional dimensions of the space 7 formed by the first splicing plate 1 and the second splicing plate 2 are smaller than the cross-sectional dimensions of the second sealing strip 32 in its free state, which are less than 1.2mm to 1.5mm. During assembly, the first splicing plate 1 and the second splicing plate 2 compress the second sealing strip 32 so that the single-sided deformation of the second sealing strip 32 is no greater than 0.5mm, that is, the length and width deformation of the second sealing strip 32 is no greater than 1mm. This increases the cross-sectional dimensions of the space 7 in this state, meaning that the first splicing plate 1 and the second splicing plate 2 compress the first sealing strip 31 and the third sealing strip 33.

[0038] In some implementations, please refer to Figure 6 As shown, when the internal pressure of the rotary dehumidifier housing is greater than the external pressure, the first splicing plate 1 and the second splicing plate 2 tend to move outward to further compress the first sealing strip 31 and the third sealing strip 33, thereby achieving a seal. Figure 6 As shown, the area filled with diagonal lines in the first sealing strip 31 and the third sealing strip 33 represents the compressed area 8.

[0039] In some implementations, please refer to Figure 7 As shown, when the internal pressure of the rotary dehumidifier housing is less than the external pressure, the first splicing plate 1 and the second splicing plate 2 tend to move inward to further compress the first sealing strip 31 and the third sealing strip 33 to achieve a seal. Figure 7 As shown, the area filled with diagonal lines in the first sealing strip 31 and the third sealing strip 33 represents the compressed area 8.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
