Abstract
Description
Technical Field
[0001] The utility model relates to an exhaust filter mechanism, in particular to an exhaust filter mechanism for a medical fabric drying machine. Background Art
[0002] Medical fabrics can be roughly divided into: ordinary textiles, non-woven fabrics, knitwear, special fabrics (such as perforated fabrics and other fabrics with good air permeability, which can be used for medical products such as skin patches). Some medical fabrics can be reused. During the reuse process, the medical fabrics need to be cleaned, disinfected, dried, etc. to avoid cross infection. The drying process now usually uses a dryer to dry the medical fabrics. Drying with a dryer can reduce the possibility of external contamination and has better cleanliness. When drying medical fabrics, a large dryer is used to dry the medical fabrics. The hot air after heat exchange flows through the surface of the medical fabrics, so that the hot air takes away the moisture on the medical fabrics and the clothes are dried. The existing dryers usually directly set a multi-layer filtering mechanism on the door body or the inner side of the door body to filter the exhaust air to prevent the fluff falling from the medical fabrics from polluting the air. However, this will increase the flow resistance of the air in the medical fabric dryer and affect the drying effect of the medical fabrics. Utility Model Content
[0003] The utility model aims to provide an exhaust filter mechanism for a medical fabric dryer, which can have a good air flow effect and a good filtering effect on the exhaust air.
[0004] The technical solution of the utility model is as follows: an exhaust filtering mechanism of a medical fabric dryer comprises a dryer body, a coarse filter plate is provided at the exhaust port at the upper end of the dryer body, an exhaust pipe is provided at the rear side of the coarse filter plate, a fine filter box is provided at the rear side of the exhaust pipe, a limit seat is provided in the fine filter box, a base is provided in the limit seat, an air inlet pipe is provided in the base, interfaces at both ends of the air inlet pipe are respectively located in the middle of the upper end surface of the base and the side of the base, a conduit connected to the exhaust pipe is provided at the interface of the air inlet pipe located on the side of the base, a plurality of groups of coaxially arranged filter cartridges are provided on the base, an end cover which can rotate relative to the filter cartridge is provided at the upper end of the filter cartridge, a detachable scraper is provided at the lower side of the end cover, and a motor for driving the end cover to rotate is provided on the upper side of the end cover.
[0005] In the aforementioned exhaust filter mechanism of a medical fabric dryer, in the multiple groups of filter cartridges arranged coaxially, the radius of the sieve holes on the inner filter cartridge is greater than the radius of the sieve holes on the outer filter cartridge.

DETAILED DESCRIPTION
[0012] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0013] Embodiment. A medical fabric drying machine exhaust filter mechanism, comprising: Figure 1-2 As shown, it includes a dryer body 1, a coarse filter plate 2 is provided at the exhaust port at the upper end of the dryer body 1, an exhaust pipe 3 is provided on the rear side of the coarse filter plate 2, a fine filter box 4 is provided on the rear side of the exhaust pipe 3, a limit seat 5 is provided in the fine filter box 4, a base 6 is provided in the limit seat 5, an air inlet pipe 7 is provided in the base 6, interfaces at both ends of the air inlet pipe 7 are respectively located in the middle of the upper end surface of the base 6 and the side of the base 6, a conduit 8 connected to the exhaust pipe 3 is provided at the interface of the air inlet pipe 7 located on the side of the base 6, a plurality of groups of coaxially arranged filter cartridges 9 are provided on the base 6, an end cover 10 rotatable relative to the filter cartridge 9 is provided on the upper end of the filter cartridge 9, a detachable scraper 11 is provided on the lower side of the end cover 10, and a motor 12 for driving the end cover 10 to rotate is provided on the upper side of the end cover 10.
[0014] In the plurality of groups of filter cartridges 9 arranged coaxially, the radius of the sieve holes on the inner filter cartridge 9 is greater than the radius of the sieve holes on the outer filter cartridge 9 .
[0015] A cleaning brush 13 corresponding to the filter cartridge 9 is disposed on one side of the scraper 11, a mounting block 14 with a circular cross-section is disposed on the upper end of the scraper 11, and an arc guide groove 15 symmetrical to the center of the mounting block 14 is disposed at the edge of the mounting block 14.
[0016] The upper end of the end cover 10 is provided with a stepped mounting groove 16 with a radius smaller than that of the mounting block 14 , the mounting groove 16 is provided with a limiting column 17 corresponding to the arc guide groove 15 , and the limiting column 17 is provided with a limiting nut 18 .
[0017] Principle of the utility model: The utility model uses a coarse filter plate 2 to filter the exhaust port of the dryer body 1 to prevent some larger impurities from entering the exhaust pipe 3. Then the air will be sent to the fine filter box 4 and sent from the interface on the side of the base 6 through the conduit 9. The conduit 9 and the air inlet pipe 7 can be quickly connected through a quick connector. The air will flow along the air inlet pipe 7 and finally be discharged from the outlet of the air inlet pipe 7 in the middle of the upper end surface of the base 6. The gas will pass through multiple groups of filter cartridges 9 from the inside to the outside, and the filtering accuracy on the filter cartridges is continuously improved, so that the discharged air is kept in a relatively clean state. The utility model adopts a coaxially arranged filter cartridge 9, and the filtering area on the multiple groups of filter cartridges 9 from the inside to the outside is continuously increased, which can prevent the flow effect of the gas from being affected during the process of increasing the filtering accuracy of the filter cartridge 9. The utility model can drive the end cover 10 to rotate relative to the filter cartridge 9 through the motor 12. The motor 12 is fixed on the box cover of the fine filter box 4. The output shafts of the end cover 10 and the motor 12 can be quickly connected by means of a block and a slot. The end cover 10 and the filter cartridge 9 can be connected by a rotary dynamic seal. During the rotation of the end cover 10, the cleaning brush 13 on the scraper 11 will clean the filter cartridge 9 to prevent blockage. The limit seat 5 outside the base 6 can prevent the base and the filter cartridge from shifting under the action of the motor, affecting the self-cleaning effect. When cleaning, the limit nut 18 can be loosened to allow the mounting block 14 to rotate in the mounting groove 16. The cleaning angle of the cleaning brush can be adjusted by cooperating with the arc guide groove 15 and the limit column 17. After adjustment, the limit nut can be tightened again to determine the angle between the scraper 11 and the inner surface of the filter cartridge 9. When the scraper 11 and the cleaning brush need to be replaced, the mounting block 14 together with the scraper and the cleaning brush 13 can be removed by disassembling the limit nut to prevent the cleaning brush 13 from being worn and affecting the self-cleaning effect.
