Description

Technical Field

[0001] The utility model belongs to the technical field of fresh air air conditioning air filtration, and relates to an installation mechanism for a pre-filtering device of a MAU fresh air unit. Background Art

[0002] In order to effectively extend the service life of the primary filter, a pre-filter device is usually installed in front of the primary filter of the MAU fresh air unit. The pre-filter device is a white fiber non-woven fabric, which mainly filters dust particles with a particle size larger than 5.0um. The pre-filter device is replaced frequently during use.

[0003] However, the existing MAU pre-filter device replacement method requires multiple people to collaborate to replace it, which consumes a lot of human resources, has low replacement efficiency, and involves the risk of high-altitude operations. Utility Model Content

[0004] The utility model aims to solve the deficiencies of the existing MAU fresh air unit pre-filter device replacement technology, and provides a MAU fresh air unit pre-filter device installation mechanism to reduce the use of manpower and the risk of high-altitude operations, and improve the replacement efficiency of the pre-filter device.

[0005] The utility model is achieved in this way:

[0006] A mounting mechanism for a pre-filter device of a MAU fresh air unit, the mounting mechanism comprising: a frame, bearings are symmetrically mounted in the frame, a transmission shaft is embedded in the bearings, two sets of winch drums are mounted on the transmission shaft, and a manual drive wheel is mounted at the end of the transmission shaft; two sets of pulleys are mounted on the top of the frame, and the two sets of winch drums are connected to the two sets of pulleys by steel wire ropes.

[0007] Use the end of the fixing clip to connect with the steel wire rope, fix the white fiber non-woven fabric with the positioning clip, adjust it to the installation position, and insert the positioning pin to complete the positioning.

[0008] Furthermore, the bearings are symmetrically installed at 1.5 meters from the bottom to the top of the frame; two sets of pulleys are installed at one-third of the top of the frame; and two sets of winch drums are installed at one-third of the top of the transmission shaft.

[0009] Furthermore, a universal wheel is installed at the bottom of the frame, and the universal wheel is installed at the bottom of the frame for moving the frame.

[0010] Compared with the prior art, the utility model can save costs, save manpower and improve production capacity after it is put into use. This device is a new device. In the existing field, the pre-filter device of the fresh air unit is operated and replaced by multiple people climbing up. After the whole device is put into use, all operations can be completed by a single person on the ground, which can reduce manpower, reduce the risk of people climbing up, and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a structural schematic diagram of an installation mechanism for a pre-filter device of a MAU fresh air unit of the utility model;

[0012] Among them, 1-frame; 2-universal wheel; 3-bearing; 4-pulley; 5-winch; 6-fixing clamp; 7-manual driving wheel; 8-positioning pin; 9-wire rope; 10-transmission shaft; 11-white fiber non-woven fabric. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the following examples are given to further illustrate the utility model in detail. It should be noted that the specific implementation described here is only used to explain the utility model, and is not used to limit the utility model.

[0014] like Figure 1 As shown, an installation mechanism of a pre-filter device of a MAU fresh air unit of the utility model includes: a frame 1, a universal wheel 2 installed at the bottom of the frame for moving the frame, a bearing 3 symmetrically installed at 1.5 meters from the bottom to the top of the frame, a transmission shaft 10 embedded in the bearing 3, two sets of winch drums 5 are installed at one-third of the transmission shaft 10, and a manual driving wheel 7 is installed at the end, two sets of pulleys 4 are installed at one-third of the upper part of the frame 1, the winch drum 5 is connected to the pulley 4 by a wire rope 9, and the end of the fixing clamp 6 is connected to the wire rope 9, and after the positioning clamp 6 fixes the white fiber non-woven fabric 11, it is adjusted to the installation position, and the positioning pin 8 is inserted to complete the positioning.

[0015] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
