[0031] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figures 1 to 7 As shown, a rolling filter for easy replacement of filter cotton includes a frame 1, a material receiving group 2, a driving unit 3 and a material discharging group 4, wherein the material receiving group 2 includes a material receiving roller 21 rotatably arranged at the bottom of the frame 1, the driving unit 3 is arranged on the frame 1 and is used to drive the material receiving roller 21 to rotate, the material discharging group 4 includes a material discharging box 42 slidably arranged on the frame 1 and a material discharging roller 41 rotatably arranged in the material discharging box 42, the material discharging roller 41 is parallel to the material receiving roller 21 and slides up and down relative to the material receiving roller 21; the rolling filter also includes a lifting component 5, the lifting component 5 is used to drive the material discharging roller 41 and the material discharging box 42 to slide up and down, specifically, the lifting component 5 It includes a lifting motor 51, a reel 52 and a rope 54. The lifting motor 51 is arranged on the top of the frame 1. The reel 52 and the guide wheel 53 are rotatably arranged on the top of the frame 1. The reel 52 and the guide wheel 53 are rotated through a bearing seat. The method of realizing rotation through a bearing seat is a prior art and will not be explained in detail here. Each group of the reels 52 is provided with a gear 521, and the two groups of gears 521 are meshed and can rotate relative to each other. The output shaft of the lifting motor 51 is fixedly connected to one of the reels 52, one end of the rope 54 is fixedly connected to the reel 52, and the other end of the rope 54 is fixedly connected to one side of the discharge box 42 through the guide wheel 53.

[0033] The lifting motor 51 is started, driving the reel 52 connected thereto to rotate. Since the two gears 521 are meshed and can rotate relatively, the two reels 52 rotate relatively and each lowers the rope 54 connected thereto. The guide wheel 53 guides the rope 54, and finally drives the discharge box 42 to slide down to the bottom of the frame 1 and above the receiving roller 21. A person can insert a new filter cotton roll onto the discharge roller 41 in the discharge box 42, and then manually remove the head of the new filter cotton roll and roll it onto the receiving roller 21.

[0034] The lifting motor 51 drives the two reels 52 to rotate relative to each other again, so that the rope 54 is wound around the reels 52, and then the discharge box 42 slides upward to the top of the frame 1. At this time, the new filter cotton covers the entire frame 1. When the airflow passes through the roller filter of this embodiment, the dust and debris in the gas are filtered on the new filter cotton. After running for a period of time, the new filter cotton will become dirty. Since the pressure difference of the new filter cotton is small and the pressure difference of the dirty filter cotton is large, the degree of dirtiness can be identified by the pressure difference gauge.

Among them, the structure of the hinge and the latch lock, as well as the rotation through the bearing 25 and the hinge, and the disassembly and connection through the latch lock are all existing technologies, and will not be described in detail here. The material collection box 22 supports the material collection roller 21 and the dirty filter cotton. When the material collection roller 21 completes the winding of all the dirty filter cotton, the dirty filter cotton roll must be taken out to ensure that the material collection roller 21 can be used for the next operation. Open the latch lock, at this time the lock buckle 24 can be rotated, the second semi-arc plate 241 is separated from the first semi-arc plate 231, and the worker can lift the other end of the material collection roller 21 and take one end out of the bearing 25. At this time, the dirty filter cotton roll on the material collection roller 21 can be taken off for the next step. After that, the two ends of the material collection roller 21 can be respectively installed again between the bearing 25 and the second semi-arc plate 241 and the first semi-arc plate 231 to ensure that the material collection roller 21 can continue to rotate.

[0040] As an implementable embodiment, the driving unit 3 includes a cotton rolling motor 31, a driving gear, a driven gear and a chain 32. The cotton rolling motor 31 is arranged on the frame 1. The output shaft of the cotton rolling motor 31 is fixedly connected to the driving gear. The driven gear is fixedly connected to one end of the receiving roller 21 passing through the bearing 25. The chain 32 is sleeved on the driving gear and the driven gear. The cotton rolling motor 31 is started, driving the driving gear, the driven gear and the chain 32 to rotate, and then driving the receiving roller 21 to rotate. The receiving roller 21 rotates to reel in the dirty filter cotton. When the receiving roller 21 rotates, since the new filter cotton is connected between it and the unloading roller 41, it can drive the unloading roller 41 to rotate. The unloading roller 41 rotates to finally unwind the new filter cotton.

[0041] As an implementable embodiment, the bottom of the frame 1 is also rotatably provided with a receiving guide roller 26, and the receiving guide roller 26 is located at the rear side of the receiving roller 21; the discharging guide roller 43 is rotatably provided on the discharging box 42, and the discharging guide roller 43 is located at the rear side of the discharging roller 41, and the receiving guide roller 26 is parallel to the receiving guide roller 26. The receiving guide roller 26 and the discharging guide roller 43 guide the new filter cotton connected between the receiving roller 21 and the discharging roller 41. Among them, the receiving guide roller 26 and the discharging guide roller 43 are both rotated through bearings (not shown in the figure). The method of rotating through bearings is a prior art and will not be described in detail here.

[0042] For further information, see Figure 1 The rear side of the discharge box 42 is fixedly connected with a fixed plate, and the discharge guide roller 43 is rotatably set on the fixed plate.

[0043] As an implementation method, two support frames 44 are arranged on the discharge box 42, each of which is provided with a material support slot. The two ends of the discharge roller 41 are respectively inserted into the two material support slots and can rotate. Each of the material support slots has an arc. Figure 7 The support slots of this structure can also limit the end of the unwinding roller 41, so that the end of the unwinding roller 41 is not easy to fall off, ensuring the normal rotation of the unwinding roller 41. The unwinding box 42 supports the unwinding roller 41 and the new filter cotton. When the unwinding roller 41 completes the unwinding of the new filter cotton, when the new filter cotton roll is to be put in again, the two ends of the unwinding roller 41 are taken out from the two support slots respectively, and then the new filter cotton roll can be put on the unwinding roller 41 again, and the two ends of the unwinding roller 41 are respectively inserted into the two support slots again to ensure that the receiving roller 21 can continue to rotate and unwind.

[0044] As an implementable method, baffles 7 are provided at both ends of the discharge roller 41 and the receiving roller 21, and a plurality of winding posts 71 are evenly provided on the baffle 7 of the receiving roller 21, and the plurality of winding posts 71 are arranged in a ring shape with the receiving roller 21 as the center. The baffle 7 on the discharge roller 41 limits the position of the new filter cotton roll. The baffle 7 on the receiving roller 21 limits the position of the dirty filter cotton roll. The worker inserts the new filter cotton roll into the discharge roller 41 in the discharge box 42, and then manually disassembles the head of the new filter cotton roll and rolls it onto the winding posts 71 of the receiving roller 21. The winding posts 71 fix the head of the new filter cotton roll on the receiving roller 21, ensuring that the receiving roller 21 can roll up the dirty filter cotton when it rotates.

[0045] As an implementable embodiment, the frame 1 includes a base 11, a top plate 12, and an outer frame 13 fixedly connected between the base 11 and the top plate 12, the receiving roller 21 is arranged on the base 11, the driving unit 3 is arranged on the outer frame 13, the discharge box 42 is slidably arranged on the outer frame 13, the lifting motor 51 is arranged on the top of the top plate 12, and the reel 52 and the guide wheel 53 are both rotatably arranged on the top of the top plate 12; a plurality of beams 14 are arranged on the outer frame 13, and an iron net is fixedly connected between two adjacent beams 14. The top plate 12 limits the highest position of the discharge box 42 sliding upward.

[0046] When the airflow passes through the rolling filter of this embodiment, dust and impurities in the air are filtered on the new filter cotton, and then the filtered air passes through the iron net and enters the entrance of the large-sized ventilation duct or the entrance of the large-sized air purification unit. The iron net is used to protect the filter cotton and intercept the filter cotton.

[0047] For further information, see Figure 1 Two adjacent end surfaces of the beams 14 are provided with connection holes, and the iron mesh is fixedly connected between the two beams 14 through the connection holes.

[0048] As an implementation method, the rolling filter further includes a meter counter 6 disposed on the frame 1 (i.e., the outer frame 13), and the meter counter 6 is located below the discharge box 42 and above the receiving roller 21. The meter counter 6 measures the moving length of the dirty filter cotton (generally, the value of the filter cotton discharge and collection distance is set in advance each time), and thus completes a single filter cotton replacement action.

[0049] As an implementable embodiment, the rolling filter further includes a control box 8, and the control box 8 is used to control the working states of the lifting motor 51, the cotton rolling motor 31, the meter 6 and the pressure difference indicator.

[0050] The process of using and replacing the filter cotton of the rolling filter of this embodiment is as follows: the lifting motor 51 is started, driving the reel 52 connected thereto to rotate. Since the two gears 521 are meshed and can rotate relatively, the two reels 52 rotate relatively and each lower the rope 54 connected thereto. The guide wheel 53 guides the rope 54, and finally drives the discharge box 42 to slide down to the bottom of the outer frame 13 and above the receiving roller 21. The worker can insert a new filter cotton roll onto the discharge roller 41, and then manually disassemble the head of the new filter cotton roll and roll it onto the receiving roller 21.

[0051] The lifting motor 51 drives the two reels 52 to rotate relative to each other again, so that the rope 54 is wound around the reel 52, and then the discharge box 42 slides upward to the top plate 12. At this time, the new filter cotton covers the entire frame 1, and the dust and debris in the gas are filtered on the new filter cotton. Then the filtered gas enters the entrance of the large-sized ventilation duct or the entrance of the large-sized air purification unit through the iron mesh. After running for a period of time, the new filter cotton will become dirty. Since the pressure difference of the new filter cotton is small and the pressure difference of the dirty filter cotton is large, the degree of dirtiness can be identified by the pressure difference meter. When the pressure difference of the dirty filter cotton reaches the pre-set pressure difference value, the meter 6 also works, and the cotton winding motor 31 starts, driving the receiving roller 21 to rotate, and the receiving roller 21 rotates to realize the winding of the dirty filter cotton. When the receiving roller 21 rotates, since the new filter cotton is connected between it and the discharge roller 41, it can drive the discharge roller 41 to rotate, and the discharge roller 41 rotates to finally realize the unwinding of the new filter cotton, that is, the single filter cotton replacement action is completed. When the filter cotton rolls in the discharge box 42 are completely discharged, the discharge box 42 is lowered again and new filter cotton rolls are put in again.
