Description

Technical Field

[0001] The invention patent relates to the field of air purification equipment, specifically a self-cleaning coiled filter. Background Art

[0002] With the rapid development of industry, air pre-filtration systems are installed in some places where the space is relatively narrow and ventilation is required. Traditional filters are generally made of materials such as chemical fiber cloth and nylon mesh. When new air enters the filtration system with a large amount of dust and particulate matter, it will be deposited on the filter material. As time goes by, the dust holding capacity of the filter material decreases, and the resistance becomes greater and greater, which will eventually cause the filter to become scrapped and can no longer filter the air. At this time, the filter material needs to be replaced frequently, which has high consumable costs, and at the same time, the narrow space makes manual replacement inconvenient.

[0003] The wound filters currently available on the market are installed in relatively narrow spaces and require frequent replacement of air filter materials, which are mostly fluffy rolls. After interception filtration, the filter materials gain a lot of weight, making it very inconvenient to replace manually in a narrow environment. The installation consumables cost is high and cannot meet the existing demand for low cost, long-term operation and low maintenance costs.

[0004] Therefore, it is necessary to develop a self-cleaning wound filter to solve the complexity and tediousness caused by cleaning and replacement work, reduce manual operation costs, increase filter material usage time and save the cost of replacing filter cotton consumables.

[0028] The present invention is further described below in conjunction with the accompanying drawings.

[0029] like Figure 1-3 As shown, the patent of the present invention discloses a self-cleaning winding filter, comprising: a filter frame 1, in which a feeding device 3, a guide roller assembly 5 and a receiving device 4 are sequentially arranged, and two dust removal ports 7 are respectively arranged at the feeding / discharging end of the feeding device 3 and the feeding / discharging end of the receiving device 4, and the two dust removal ports 7 are connected to a three-way valve (not shown in the figure) located on the filter frame 1 through a connecting pipe (partially shown in the figure, subsequent content is not marked), and the third end of the three-way valve is connected to a dust collector 6 arranged outside the filter, and a filter cotton roll 2 is installed in the feeding device 3, and the filter cotton roll 2 includes a fixed cylinder 21 and a filter cotton 22 wound on the outer wall of the fixed cylinder 21, and the end of the filter cotton 22 close to the fixed cylinder 21 is fixedly connected to the outer wall of the fixed cylinder 21.

[0030] Based on the above structure, Figure 1-3 As shown, when installing the filter cotton roll 2, the feeding device 3 fixes the fixed cylinder 21 with the filter cotton 22 wound on the outside, and the feeding device 3 conveys the filter cotton 22, and the filter cotton 22 is manually pulled through the guide roller assembly 5 and to the output end of the receiving device 4, and then the filter cotton 22 is pulled into the receiving device 4 for preliminary winding;

[0031] Afterwards, in daily use, the filter cotton 22 between the feeding device 3 and the receiving device 4 is defined as the filter surface because it is facing the input end and the output end of the filter. After the filter surface has been filtered for a long time, the receiving device 4 rolls up the filter cotton 22, and the original filter surface is displaced and passes through the dust suction port 7 located at the output end of the receiving device 4. The vacuum cleaner 6 works and applies suction to the dust suction port 7 through the connecting pipe. The dust suction port 7 absorbs dust and impurities on the original filter surface.

[0032] At the same time, during the winding process of the receiving device 4, the feeding device 3 transports the filter cotton 22, and transports the transported filter cotton 22 to the input end and the output end of the filter to form a new filter surface, and repeats this process; when there is no filter cotton 22 in the feeding device 3 that can be further transported, the feeding device 3 and the receiving device 4 both perform the above steps in reverse, and transport the filter cotton 22 of the receiving device 4 to the feeding device 3. During this process, the dust suction port 7 at the output end of the feeding device 3 absorbs dust and impurities from the original filter surface, thereby achieving the effect of repeatedly utilizing the primary filter cotton through the self-cleaning function. At the same time, the feeding device 3 can be used to transport the filter cotton 22 to the input end and the output end of the filter to form a new filter surface, and the self-cleaning function can be used to repeatedly utilize the primary filter cotton. At the same time, the frequency and difficulty of manual cleaning are reduced, and the maintenance cost is reduced.

[0033] Preferably, the three-way valve is used to control the suction force of the vacuum cleaner to act on any dust removal port 7, thereby increasing the efficiency of the vacuum cleaner 6 in sucking dust and impurities from the original filter surface.

[0034] Further, such as Figure 2-4 As shown, in order to facilitate loading and unloading of the filter cotton roll 2, the feeding device 3 includes a motor 31 fixed on the filter frame 1, a filter cotton roll 2, a mounting frame 321, a first mounting plate 331, a first fixing seat 34, a second fixing seat 35 and an electric push rod 32. The mounting frame 322 and the first mounting plate 331 are fixedly mounted on the upper and lower parts of the inner wall of the filter frame 1 respectively. The electric push rod 32 is fixedly connected to the bottom end of the mounting frame 322. The second fixing seat 35 is rotatably connected to the execution end of the electric push rod 32. The first fixing seat 34 is rotatably connected to the top end of the first mounting plate 331 through the connecting shaft 33, and is used to clamp and fix the two ends of the filter cotton roll 2 with the second fixing seat 35. The bottom end of the connecting shaft 33 passes through the first mounting plate 331 and is drivingly connected to the first sprocket (not shown in the figure). The execution end of the motor 31 is drivingly connected to the second sprocket (not shown in the figure), and the first sprocket and the second sprocket are drivingly connected through a first chain (not shown in the figure).

[0035] When installing the filter cotton roll 2, the filter cotton roll 2 is placed between the first fixing seat 34 and the second fixing seat 35, and one end of the fixing cylinder 21 is kept sleeved and fixed on the first fixing seat 34. Then, the execution end of the electric push rod 32 extends out and pushes the second fixing seat 35 to move toward the other end of the fixing cylinder 21 until the second fixing seat 35 is inserted into the other end of the fixing cylinder 21 and clamps the fixing cylinder 21 with the first fixing seat 34. When removing the filter cotton roll 2, the execution end of the electric push rod 32 can be retracted.

[0036] When the feeding device 3 is conveying / reeling the filter cotton 22 , the motor 31 drives the connecting shaft 33 to rotate through the second sprocket, the first chain and the first sprocket in sequence. The connecting shaft 33 drives the fixed cylinder 21 to rotate through the first fixed seat 34 , and the second fixed seat 35 rotates with the fixed cylinder 21 .

[0037] Further, such as Figure 2-4 As shown, in order to facilitate the insertion of the first fixing seat and the second fixing seat into the fixing cylinder and clamp the fixing cylinder, the outer wall diameters of the first fixing seat 34 and the second fixing seat 35 are gradually increased from the filter cotton roll 2 to the outer wall of the symmetrical side filter frame 1.

[0038] Further, such as Figure 2-3 As shown, the material receiving device 4 includes a material receiving shaft 42, and two ends of the material receiving shaft 42 are rotatably connected to two second mounting plates 43, and the mounting plates 43 are fixedly connected to the inside of the filter frame 1. One end of the material receiving shaft 42 passes through the second mounting plate 43 on the corresponding side, and is transmission-connected to the third sprocket 421. The execution end of the motor 31 is transmission-connected to the fourth sprocket (not shown in the figure), and the third sprocket 421 is transmission-connected to the fourth sprocket through the second chain (not shown in the figure); when the material receiving device 4 is conveying / reeling the filter cotton, the motor 31 drives the material receiving shaft 42 to rotate through the fourth sprocket, the second chain and the third sprocket 421 in turn.

[0039] Further, such as Figure 4 As shown, in order to facilitate the control of power transmission and cutting off of the motor and the material receiving motor, the execution end of the motor 31 is respectively connected to the second sprocket and the fourth sprocket 411 through two sprocket clutches (not shown in the figure).

[0040] Furthermore, the guide roller assembly 5 includes two steering rollers 51 respectively arranged at the output end of the feeding device 3 and the output end of the receiving device 4, the steering roller 51 is rotatably connected to the inner wall of the filter frame 1, and the steering roller 51 is in contact with the surface of the filter cotton 22; the two steering rollers 51 are used to steer the filter cotton 22 between the output end of the feeding device 3 and the output end of the receiving device 4, and to form a plane between the two steering rollers 51 due to the tension.

[0041] Further, such as Figure 2 and 3 As shown, in order to increase the filtering area of ​​the filtering surface, the guide roller assembly 5 also includes a traction assembly arranged between the feeding device 3 and the receiving device 4, and the traction assembly includes N traction rollers 52 rotatably connected to the filter frame 1, and the traction rollers 52 are in contact with the surface of the filter cotton 22. The N traction rollers 52 are evenly arranged at the output end and the input end of the filter in a V-shaped staggered manner. The number of traction rollers 52 on the output end side of the filter is N+1 compared to the number of traction rollers 52 on the input end side of the filter.

[0042] When installing the filter cotton roll 2, the filter cotton 22 is evenly arranged and wound along the V-shaped offset in the process of being pulled from the steering roller 51 on the side of the feeding device 3 to the steering roller 51 on the side of the receiving device 4, thereby increasing the filtering area of ​​the filter cotton 22 in the effective space, so as to ensure that a larger flow of air can pass through while allowing the entire filtering process to be carried out continuously and efficiently.

[0043] Further, such as Figure 2 and 3 As shown, two guide frame arrays are symmetrically installed in the filter frame 1 of the traction assembly, and the guide frame array is composed of a plurality of guide frames 53 with U-shaped cross-sections. The guide frames 53 are opened toward the traction roller 52, and the N guide frames 53 are evenly arranged in a V-shaped staggered manner and correspond to the N traction rollers 52. The number of the guide frames 53 is N-1 compared to the number of the traction rollers 52;

[0044] When the filter cotton 22 is sent out from the feeding device 3, it first contacts the traction roller 52 in the traction assembly. Then, after the filter cotton 22 turns, the two ends of the filter cotton 22 are respectively embedded in the guide frame 53. The guide frame 53 provides a limit for the measuring end of the moving filter cotton 22 to prevent the filter cotton 22 from offsetting or running off track during the transportation process.

[0045] Furthermore, a differential pressure gauge for sensing the pressure difference between the input and output ends of the filter is installed in the filter, and the sensing ends of the differential pressure gauge are respectively installed at the input and output ends of the filter, and the differential pressure gauge signal is connected to an external control unit, and the external control unit is connected to the motor 31, the receiving motor 41 and the vacuum cleaner 6 signal;

[0046] The setting of the differential pressure gauge can detect the pressure difference between the input and output ends of the filter in real time. When the pressure difference is ≥ the predetermined value, the external control unit starts the motor 31, the material collection motor 41 and the vacuum cleaner 6, thereby conveying, reeling and removing dust and impurities from the original filter surface.

[0047] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and invention concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
