Description

Technical Field

[0001] The utility model relates to the technical field of rotary dehumidifiers, and in particular to a rotary wheel protection device for rotary dehumidifiers. Background Art

[0002] Rotary dehumidifier is an important branch of air conditioning field, and is a typical representative of temperature control dehumidification. The air solid adsorption separation adopts the internationally used rotary metal silicate desiccant adsorption body. During the dehumidification process, the adsorption turntable rotates slowly under the drive of the drive device. When the adsorption wheel adsorbs water molecules in the air treatment area to saturation, it enters the regeneration area and is desorbed and regenerated by high-temperature air. This process is repeated, and the dry air is continuously sent to the designated space after temperature adjustment, achieving high-precision temperature and humidity control.

[0003] Since the processing area and regeneration area on the rotor are often asymmetrically arranged, and the processing area and regeneration area usually only occupy a continuous part of the area, the force of the incoming air on the rotor and the force of the outgoing air on the rotor cannot effectively offset each other, resulting in uneven force on the rotor and unstable rotation, especially for the rotor with the processing area and regeneration area each occupying half, the rotation stability is more affected. Therefore, a rotor protection device for a rotary dehumidifier is needed. Utility Model Content

[0004] The purpose of the present application is to provide a rotary wheel protection device for a rotary dehumidifier to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a rotary wheel protection device for a rotary dehumidifier, comprising a wheel frame and a rotary wheel rotatably connected to the inner side of the wheel frame, and further comprising:

[0006] An auxiliary fixing frame, the auxiliary fixing frame being detachably fixedly connected to a side end of the wheel frame;

[0007] A partition structure, wherein the partition structure comprises a first sealing strip and a second sealing strip, wherein the first sealing strip and the second sealing strip are integrally arranged crosswise, and the crossing position is located at the center of the rotating wheel, wherein the first sealing strip and the second sealing strip are both fixedly connected to the auxiliary fixing frame, and the first sealing strip and the second sealing strip are both arranged to be sealed and slidably fitted with the rotating wheel;

[0008] The first sealing strip and the second sealing strip together separate the rotary wheel into two processing zones and two regeneration zones, and the processing zone is spaced apart from the regeneration zone.

[0009] Preferably, the auxiliary fixing frame and the wheel frame are fixed to each other via fixing bolts, and a positioning structure is connected between the wheel frame and the auxiliary fixing frame.

[0010] Preferably, the positioning structure comprises a positioning column fixedly connected to the auxiliary fixing frame and a positioning groove arranged on the wheel frame, and the positioning column is matched with the positioning groove.

[0011] Preferably, a mounting ring is fixedly sleeved on the circumference of the rotating wheel, and a plurality of balls are evenly arranged on the side end of the mounting ring close to the auxiliary fixing frame, and an annular rolling groove matching the balls is arranged on the side end of the auxiliary fixing frame close to the rotating wheel.

[0012] Preferably, a sealing ring is provided at the annular rolling groove, and the sealing ring is fixedly connected to the auxiliary fixing frame, and the sealing ring is slidably fitted with the mounting ring.

[0013] Preferably, the sealing ring is an elastic sealing ring.

[0014] In summary, the technical effects and advantages of the utility model are:

[0015] 1. In the utility model, a partition structure including a first sealing strip and a second sealing strip is provided, and the first sealing strip and the second sealing strip are integrated and cross-arranged, and the cross-position is located at the center of the wheel.
