Description

Technical Field

[0001] The utility model belongs to the technical field of dehumidifier accessories, and particularly relates to a rotary dehumidifier and an adjustable rotary wheel sealing structure thereof. Background Art

[0002] In order to improve the sealing performance of the rotary dehumidifier during operation, the following sealing solutions are usually adopted:

[0003] 1) Scraper seal: A scraper seal is set on the outer cylindrical surface of the dehumidifier's partition close to the impeller, so that the scraper is close to the partition during the rotation of the impeller. In order to reduce the friction coefficient, polytetrafluoroethylene material is attached to the side of the scraper involved in the friction to reduce friction and increase wear resistance.

[0004] 2) Silicone sealing strip sealing: Sealing is achieved by setting a silicone sealing strip between the rotor and the partition.

[0005] 3) Ω-type seal sealing: The surface of the Ω-type seal is coated with wear-resistant material and material with a low friction coefficient. The seal is fixed on the partition of the runner, and the elastic force of the seal is used to make it close to the sealing surface for sealing.

[0006] However, in actual use, it was found that the above sealing solutions all had certain problems:

[0007] Solution 1: There are problems such as poor sealing effect, low pressure resistance (generally less than 500Pa), poor surface wear resistance, etc. During continuous operation, the surface (polytetrafluoroethylene) layer of the sealing strip is gradually worn away, resulting in large resistance at the back and air leakage when the wear is severe.

[0008] Solution 2: There is a problem that the friction of the silicone sealing strip is too large, which increases the resistance of the wheel, and the sealing strip has poor wear resistance.

[0009] Solution 3: This solution is a fixed, non-adjustable structure, which has high requirements on the manufacturing and installation process of the adjustable impeller sealing structure, poor compatibility with the impeller, inability to adjust the sealing degree, resulting in the seal being tight or loose, affecting the sealing effect, and deformation or out-of-tolerance problems of components during the manufacturing or transportation process.

[0046] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0047] The most critical concept of the utility model is that through the cooperation of the movable buckle and the seal, the staff can adjust the position of the seal according to the actual situation, so as to achieve the purpose of eliminating the gap between the seal and the wheel-related device; at the same time, during assembly, the seal can be installed quickly by simply buckling it on the movable buckle, thereby effectively improving the overall disassembly and assembly efficiency.

[0048] Please refer to Figures 1 to 3 The adjustable rotor sealing structure provided by the utility model comprises a positioning baffle 1, a movable buckle 2 and a sealing member 3;

[0049] The positioning partition 1 is provided with a fixing hole;

[0050] The seal 3 is an annular structure;

[0051] The sealing member 3 is circumferentially mounted on the outer side of the fixing hole through the movable buckle 2, and the movable buckle 2 can drive the sealing end of the sealing member 3 to approach or move away from the center of the fixing hole.

[0052] From the above description, it can be seen that the beneficial effects of the utility model are: providing an adjustable rotor sealing structure, through the cooperation of the movable buckle 2 and the seal 3, the staff can adjust the position of the seal 3 according to the actual situation, so as to achieve the purpose of eliminating the gap between the seal 3 and the relevant rotor device; compared with the adjustable rotor sealing structure inside the existing dehumidifier, it can not only improve the adjustment flexibility of the seal 3 and ensure the sealing effect; at the same time, during assembly, it is only necessary to buckle the seal 3 on the movable buckle 2 to quickly complete the installation of the seal 3, thereby effectively improving the overall disassembly and assembly efficiency.

[0053] Furthermore, the above-mentioned adjustable rotor sealing structure further includes a locking member 4;

[0054] The movable buckle 2 comprises a fastener 21, a transition piece 22 and a buckle 23 which are connected in sequence;

[0055] The fastener 21 is connected to the positioning partition 1 through the locking member 4;

[0056] A gap is left between the snap-fit ​​member 23 and the positioning partition 1;

[0057] The sealing member 3 is disposed between the snap member 23 and the positioning partition 1 , and the sealing member 3 is in conflict with the positioning partition 1 through the snap member 23 .

[0058] Specifically, the fastener 21, the transition piece 22 and the snap member 23 can form a Z-shaped structure. By changing the length of the transition piece 22, the gap between the snap member 23 and the positioning partition 1 can be changed, so that the snap member 23 can be adapted to the seal 3 of any size.

[0059] From the above description, it can be seen that the design has made specific improvements to the composition structure of the active buckle 2, as well as the layout requirements between the positioning partition 1, the active buckle 2 and the seal 3, so that the seal 3 can be stably fixed on the positioning partition 1 through the active buckle 2 to avoid the seal 3 affecting the overall sealing due to shaking during operation.

[0060] Further, the fastener 21 is provided with an oblong hole;

[0061] The extending direction of the oblong hole is parallel to the radial direction of the fixing hole;

[0062] The locking piece 4 passes through the oblong hole and is connected to the positioning partition 1 .

[0063] From the above description, it can be seen that an oblong hole is provided on the fastener 21 to provide structural support for the movable buckle 2 to drive the sealing end of the seal 3 close to or away from the center of the fixing hole, so that the staff can adjust the position of the seal 3 according to actual needs to ensure that the overall sealing effect is optimal.

[0064] Furthermore, the distance between the end of the clip 23 away from the transition piece 22 and the positioning baffle 1 is smaller than the distance between the end of the clip 23 close to the transition piece 22 and the positioning baffle 1 .

[0065] From the above description, it can be seen that this design enables the snap fastener 23 to exert a larger force on the seal 3 toward the positioning partition 1, so that the seal 3 can be firmly fixed between the snap fastener 23 and the positioning partition 1, avoiding the seal 3 from shaking relative to the positioning partition 1 during operation, thereby affecting the overall sealing effect.

[0066] Further, the sealing member 3 comprises a sealing portion 31 and a clamping portion 32 connected to each other;

[0067] The sealing portion 31 and the clamping portion 32 form an annular structure;

[0068] The clamping portion 32 is disposed between the snap member 23 and the positioning partition 1 , and the clamping portion 32 is in conflict with the positioning partition 1 through the snap member 23 .

[0069] It can be seen from the above description that the design makes specific modifications to the composition structure of the seal 3 and the connection relationship between the active buckle 2 and the seal 3, so that the active buckle 2 can reliably clamp the seal 3.

[0070] Furthermore, the interior of the sealing portion 31 is hollow.

[0071] From the above description, it can be seen that the sealing part 31 is set as a hollow structure, so that the sealing part 31 can undergo elastic deformation according to the change of the pressure intensity, thereby effectively filling the gap between the sealing part 31 and the relevant wheel equipment, thereby ensuring the sealing between the seal 3 and the relevant wheel equipment.

[0072] Furthermore, a wear-resistant layer 311 and an adhesive layer 312 are provided on the outer side of the sealing portion 31;

[0073] The wear-resistant layer 311 is connected to the sealing portion 31 via the adhesive layer 312 .

[0074] From the above description, it can be seen that this design not only ensures the sealing effect of the seal 3, but also improves the wear resistance of the seal 3, thereby reducing the wear of the sealing part 31 caused by the relevant wheel equipment during rotation, so as to indirectly increase the service life of the seal 3 and thus reduce the use cost of the equipment.

[0075] Further, the clamping portion 32 is provided with a pressure strip 321;

[0076] The locking member 23 presses the clamping portion 32 via the pressing strip 321 .

[0077] It can be seen from the above description that the pressure strip 321 can increase the contact area between the buckle 23 and the clamping portion 32 to prevent the clamping portion 32 from being damaged due to long-term squeezing, thereby further increasing the service life of the seal 3.

[0078] The utility model also provides a rotary dehumidifier, comprising a rotary body 5 and any one of the above-mentioned adjustable rotary seal structures;

[0079] The rotating shaft and the fixing hole of the rotating wheel body 5 are coaxially arranged;

[0080] The sealing end of the sealing member 3 contacts the outer side surface of the rotor body 5 .

[0081] From the above description, it can be seen that the design has made specific modifications to the relevant structures of the rotary dehumidifier, as well as the layout requirements between the rotary dehumidifier and the adjustable rotary seal structure; ensuring that the rotating axis of the rotary body 5 and the fixed hole are coaxially arranged can avoid eccentric rotation of the rotary body 5 relative to the fixed hole, which affects the sealing effect between the outer side of the rotary body 5 and the seal 3, and further affects the overall dehumidification performance.

[0082] The adjustable rotary wheel sealing structure of the utility model can assist the daily dehumidification work of the rotary wheel dehumidifier.

[0088] The working principle of the utility model is as follows: first, the staff determines the size of the sealing member 3 and the number of the movable buckles 2 according to the size of the wheel body 5; then, the locking member 4 is passed through the oblong hole of the fastener 21 to preliminarily fix the movable buckles 2 on the positioning partition 1; then, the sealing portion 31 of the sealing member 3 is pre-pressed between the buckle 23 and the positioning partition 1 through the buckle 23, and the position of the locking member 4 in the oblong hole is adjusted to change the spacing between the sealing portion 31 and the outer side of the wheel body 5, until the gap between the sealing portion 31 and the outer side of the wheel body 5 is completely eliminated, and then the locking member 4 is locked to complete the assembly of the sealing member 3 and the wheel body 5.

[0089] To sum up, the utility model provides an adjustable rotor sealing structure, which enables the staff to adjust the position of the seal according to the actual situation through the cooperation of the movable buckle and the seal, so as to achieve the purpose of eliminating the gap between the seal and the relevant rotor device; compared with the adjustable rotor sealing structure inside the existing dehumidifier, it can not only improve the adjustment flexibility of the seal and ensure the sealing effect; at the same time, during assembly, it is only necessary to buckle the seal on the movable buckle to quickly complete the installation of the seal, thereby effectively improving the overall disassembly and assembly efficiency, and the wear-resistant layer arranged on the outside of the seal can also indirectly improve the durability of the seal while the seal can ensure the overall sealing performance, thereby effectively saving the use cost of the dehumidifier.
