The device replacement mechanism includes: a mucosal frame 13 connected to the top of the filter bag body 1, a fixing frame 14 is installed on the top of the mucosal frame 13, and a plug post 15 is fixedly installed on the top of the fixing frame 14; a plurality of filter holes 11 are inlaid on the surface of the filter bag body 1, and an inner filter bag 12 is installed inside the filter bag body 1; the filter bag body 1 is connected to the fixing frame 14 through the mucosal frame 13, and the plug post 15 is located directly below the mounting hole 21, and the plug post 15 is inserted into the inside of the mounting hole 21, and the thickness of the filter bag body 1 is 2 mm.

[0025] Specifically, an inner filter bag 12 is installed inside the filter bag body 1, and the surfaces of the inner filter bag 12 and the filter bag body 1 are inlaid with a plurality of filter holes 11. The liquid in the filter bag body 1 is filtered for impurities through the filter holes 11. The inner filter bag 12 increases the number of filter layers of the filter bag body 1, so that the impurity filtration is refined. At the same time, a mucosal frame 13 is installed above the filter bag body 1 and the inner filter bag 12. The mucosal frame 13 sticks the filter bag body 1 and the inner filter bag 12 under the fixed frame 14. The fixed frame 14 is connected to the outer frame 2 through the plug post 15. When the filter bag body 1 or the inner filter bag 12 needs to be replaced, it is only necessary to remove the mucosal frame 13 stuck on the filter bag body 1, so as to facilitate the later replacement of the filter bag body 1 or the inner filter bag 12.

[0026] An outer frame 2 is installed on the outside of the filter bag body 1, and a plurality of mounting holes 21 are embedded inside the outer frame 2, and brackets 22 are fixedly installed on the four sides of the bottom of the outer frame 2, and a bottom frame 23 is fixedly installed on the bottom of the bracket 22; the outer frame 2 and the bottom frame 23 are respectively located on the upper and lower sides of the filter bag body 1, and the outer frame 2 is connected to the scraper handle 3 through a rotating block 31; the filter bag body 1 is a quadrilateral structure, and the length and width of the outer frame 2 are 1.2 times that of the filter bag body 1.

[0027] Specifically, the outer frame 2 is arranged outside the filter bag body 1 to control the inlet size of the filter bag body 1. At the same time, a bracket 22 and a bottom frame 23 are installed below the outer frame 2. The bottom frame 23 supports the bottom of the filter bag body 1 so that the filter bag body 1 can withstand the impact of liquid.

[0028] The impurity scraping mechanism includes: a scraper handle 3 connected to the rear of the filter bag body 1, a swivel 34 is connected to the front of the scraper handle 3, and a telescopic column 33 is connected to the front of the swivel 34, and a mounting plate 32 is connected to the front of the telescopic column 33, and a rotating block 31 is connected to the front of the mounting plate 32; the rotating block 31 is arranged inside the outer frame 2, and the scraper handle 3 is connected to the inside of the filter bag body 1 through the swivel 34, the telescopic column 33, the mounting plate 32 and the rotating block 31. The scraper handle 3 is rotated to the inside of the filter bag body 1 through the rotating block 31, and the scraper handle 3 can be rotated at any angle through the swivel 34, and the surface of the inner filter bag 12 is also inlaid with a plurality of filter holes 11.

[0029] Specifically, a rotating block 31 is connected to the rear of the filter bag body 1, and the rotating block 31 is connected to the scraper handle 3 through a mounting plate 32, a telescopic column 33, a swivel 34, and the scraper handle 3 can be rotated through the rotating block 31 and the swivel 34 so that the scraper handle 3 is located inside the filter bag body 1. The scraper handle 3 scrapes off the impurities remaining inside the filter bag body 1 by using the setting of the telescopic column 33 to prevent the impurities from remaining inside the equipment and clogging the filter holes 11.

[0030] Working principle: First, pour the liquid to be filtered into the interior of the filter bag body 1. The interior of the filter bag body 1 is installed with an inner filter bag 12. The inner filter bag 12 increases the number of filtration layers of the filter bag body 1, and can perform multiple filtrations on impurities, so that the filter bag body 1 can filter finely. When the liquid is poured into the interior of the filter bag body 1, an impact force will be generated. An outer frame 2 is installed above the filter bag body 1. The outer frame 2 is connected to the bottom frame 23 through a bracket 22. The bottom frame 23 supports the bottom of the filter bag body 1, so that the filter bag body 1 can withstand a certain impact force and weight. After the filter bag body 1 has been used for a period of time, the filter holes 11 inlaid with the filter bag body 1 and the inner filter bag 12 will be blocked by impurities. At the same time, certain impurities will remain in the filter bag body 1 and the inner filter bag 12. The residual impurities are not easy to clean. The scraper handle 3 connected at the rear is rotated by the rotating block 31 and the rotating ring 34, so that the scraper handle 3 is located inside the filter bag body 1. The scraper handle 3 is extended by the setting of the telescopic column 33, so that the scraper handle 3 extends to the four sides of the inside of the filter bag body 1, so that the impurities remaining inside the filter bag body 1 or the inner filter bag 12 can be scraped off to avoid clogging by impurities. Finally, when the filter bag body 1 has been used for a period of time, the filter bag body 1 or the inner filter bag 12 with a slower filtration speed is removed from the mucosal frame 13, so that the filter bag body 1 is separated from the fixed frame 14 and the bottom of the outer frame 2, and it is cleaned, and then a new filter bag body 1 is replaced. The filter bag body 1 is installed again through the mucosal frame 13 on the upper surface, so that the number of filtration layers of the filter bag body 1 remains unchanged, thus completing the entire use process of the high-strength filter bag.
