Description

Technical Field

[0001] The present application relates to the technical field of magnetic levitation blower filters, and in particular to an automatic winding filter for a magnetic levitation blower and a magnetic levitation blower. Background Art

[0002] In today's industrial environment, magnetic levitation blowers are essential ventilation and air exchange equipment, and their performance stability and operational efficiency are crucial to the entire production process. However, when operating in environments with high dust concentrations, the effectiveness of their filtration systems becomes a critical issue. Currently, magnetic levitation blower filtration systems on the market generally utilize three layers of filter cotton made of different materials. This structure is designed to filter the air entering the equipment to varying degrees, ensuring internal cleanliness and preventing dust accumulation.

[0003] However, magnetic levitation blowers often operate in harsh environments, such as workshops or mines with extremely high dust concentrations. In such environments, filter wear accelerates significantly, as large amounts of dust particles constantly impact and clog the filter pads, reducing filtration efficiency or even completely rendering them ineffective. This not only increases the frequency of filter replacement but also significantly increases maintenance costs.

[0004] Furthermore, if the failed filter is not replaced in time, the filter screen may become severely clogged, which will not only reduce the efficiency of the blower, but may also cause equipment failure or even downtime. This will not only affect the normal operation of production, but also cause significant financial losses to the company.

[0005] To address these issues, we designed an automatic winding filter for magnetic levitation blowers and a magnetic levitation blower. Utilizing automatic winding technology, this filter automatically replaces the filter when it's about to fail, ensuring the continuous and stable operation of the filtration system. This not only effectively addresses the issues of frequent filter replacement and high maintenance costs, but also significantly reduces the risk of equipment failure, providing a strong guarantee for stable production.

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] See also Figures 1-6 The present application provides a new technical solution: an automatic winding filter for a magnetic levitation blower and a magnetic levitation blower, comprising a filter 2, the filter 2 being mounted on an air inlet side door panel of the magnetic levitation blower 1 and being used to filter the air entering the magnetic levitation blower 1;

[0029] The filter 2 includes a new material reel 3, an old material reel 5 and a filter screen 8. The new material reel 3 is used to place the new filter screen 8. After use, the filter screen 8 is reeled through the old material reel 5 by the driving mechanism 4 to reel the used filter screen 8.

[0030] One side of the filter screen 8 is wound inside the new material reel 3, and the other side of the filter screen 8 is wound inside the old material reel 5. The filter screen 8 is flatly placed at the air inlet of the filter 2 between the new material reel 3 and the old material reel 5 to filter the air inlet;

[0031] The driving mechanism 4 is used to roll up the used filter screen 8 into the old material reel 5 and to place the unused filter screen 8 flatly at the air inlet of the filter 2 .

[0032] A new material reel shaft 31 is provided inside the new material reel 3 for placing a new filter screen 8 , and an old material reel shaft 51 is provided inside the old material reel 5 for rolling up the used filter screen 8 .

[0033] During use, the driving mechanism 4 can drive the old material reel 51 to reel in the used filter 8, driving the filter 8 to be wound and updated in an orderly manner. The new filter 8 will be accurately placed at the air inlet, seamlessly connected, thereby successfully completing the entire filter automatic replacement process.

[0034] In some embodiments, the new material roll 3 is located on the upper side of the filter 2 , and the old material roll 5 is located on the lower side of the filter 2 .

[0035] In some embodiments, the new material roll 3 is located at the lower side of the filter 2 , and the old material roll 5 is located at the upper side of the filter 2 .

[0036] In some embodiments, the driving mechanism 4 is fixedly installed above the waste material roll 5 .

[0037] In some embodiments, a rotating shaft 9 is provided on the upper and lower sides of the filter 2, and the rotating shaft 9 is respectively located on the side of the new material roll 3 and the old material roll 5 close to the door panel. The filter 8 bypasses the two rotating shafts 9 to make the filter 8 fit more closely with the air inlet of the door panel, thereby improving the filtering effect.

[0038] In some embodiments, the filter is meticulously rolled from 7mm thick, 600mm wide primary cotton, with each roll reaching 10 meters in length. With a single replacement, the filter has a lifespan of two to three months. When the filter is nearing exhaustion, the system issues a prompt replacement reminder to ensure continuous and efficient operation.

[0039] In some embodiments, the driving mechanism 4 includes a driving motor 41, the output shaft of the driving motor 41 is connected to the main sprocket 43, and a secondary sprocket 44 is provided on one side of the used material winding shaft 51, and the main sprocket 43 and the secondary sprocket 44 are connected by a transmission chain 42; when in use, the driving motor 41 is started to drive the main sprocket 43 to rotate, and the secondary sprocket 44 is driven to rotate through the transmission chain 42, and then the used material winding shaft 51 can be driven to rotate, which can achieve the effect of winding up the used filter 8.

[0040] In some embodiments, a pressure differential sensor 7 is provided inside the magnetic levitation blower 1. The pressure differential sensor 7 is used to detect the pressure difference of the air entering the magnetic levitation blower 1 after being filtered by the filter 2. As the blower continues to run, the filter may become clogged due to long-term accumulation of dust and debris, thereby making the air intake become obstructed, and eventually forming a significant pressure difference on both sides of the filter.

[0041] At this time, the pressure difference sensor 7 will accurately compare and calculate the collected values. Once it is found that the pressure difference exceeds the preset safety threshold, the old material reel 51 at the bottom will be immediately started under the drive mechanism 4, driving the filter 8 to be wound and updated in an orderly manner. The new filter 8 will be accurately placed at the air inlet, seamlessly connected, thereby successfully completing the entire filter automatic replacement process.

[0042] The entire process does not require any human intervention or supervision, which fully demonstrates the convenience and efficiency of automation technology and brings great convenience to users.

[0043] In some embodiments, several groups of running wheels 6 are provided under the filter 2 for driving the filter 2 to move. When the filter material roll is replaced, the door panel of the magnetic levitation blower 1 is opened, and the filter 2 can be moved along the direction of rotation of the door panel under the drive of the running wheels 6, which is convenient for opening and improves the replacement efficiency. At the same time, the running wheels 6 can also play a supporting role to avoid the problem of settlement and deformation of the door panel due to the weight of the filter 2, thereby improving the service life of the equipment.

[0044] Working principle: When an automatic winding filter for a magnetic levitation blower and a magnetic levitation blower are in use, the collected values ​​will first be accurately compared and calculated through the pressure difference sensor 7. When the pressure difference exceeds the preset safety threshold, the old material winding shaft 51 at the bottom will be immediately started under the drive mechanism 4, driving the filter 8 to be wound and updated in an orderly manner. The new filter 8 will be accurately placed at the air inlet, seamlessly connected, thereby successfully completing the entire filter automatic replacement process.

[0045] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
