Description

Technical Field

[0001] This utility model relates to the technical field of filters, and in particular to a self-cleaning filter. Background Technology

[0002] During the smelting process, blockages easily occur at the interfaces of pipes of different diameters. This is mainly due to changes in flow velocity, the inertial effect of particulate matter, and the characteristics of the smelting medium. The smelting medium is often a high-temperature, corrosive, or viscous substance, which exacerbates deposition and adhesion, causing complete blockage of local flow sections in the pipe. Existing cleaning methods mostly rely on manual disassembly of pipes, which is cumbersome and poses safety hazards, making it difficult to meet the requirements of efficient and safe production. Utility Model Content

[0003] In view of this, the present invention provides a self-cleaning filter to solve the technical problem that deposits and adhesions can completely block the local flow section of a pipe, and existing cleaning methods rely on manual labor.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A self-cleaning filter includes a pipe, an impeller assembly, a torsion spring, and a cleaning assembly. The impeller assembly, the torsion spring, and the cleaning assembly are housed within the pipe. The torsion spring is sleeved on the shaft of the impeller assembly. The impeller assembly is connected to the cleaning assembly and is capable of driving the cleaning assembly to rotate. The cleaning assembly is coaxially arranged with the pipe. The cleaning component has a closed state and an extended state. The pipe is open in both the closed and extended states. The orifice size of the cleaning component in the closed state is smaller than that in the extended state. When the self-cleaning filter is not clogged, the water flow inside it can rotate the impeller assembly. The rotation of the impeller assembly can cause the torsion spring to store energy until it reaches equilibrium, and cause the cleaning component to change from the extended state to the closed state. When the self-cleaning filter is clogged, the torsion spring releases potential energy to rotate the impeller assembly and reset the cleaning component from the closed state to the extended state.

[0005] In some embodiments of the self-cleaning filter, the conduit includes a first unit and a second unit, the first unit and the second unit having different diameters to form an annular platform at the connection between the first unit and the second unit, and the cleaning component is mounted on the annular platform.

[0006] In some embodiments of the self-cleaning filter, the cleaning assembly includes a fixed disc, a rotating disc, and multiple blades. The rotating disc abuts against the inner wall of the first unit. The rotating disc and the fixed disc are coaxially arranged with the pipeline. The fixed disc is fixed to the annular platform. Both the fixed disc and the rotating disc have channels of the same diameter that communicate with the inside of the pipeline. The multiple blades are evenly distributed circumferentially on the rotating disc and are disposed between the rotating disc and the fixed disc. One end of each blade is rotatably connected to the fixed disc, and the other end is rotatably connected to the rotating disc. The impeller assembly is connected to the rotating disc via a torsion spring. When the impeller assembly rotates in both directions, it can drive the rotating disc to rotate, so that each blade can rotate in a direction closer to or away from the pipeline axis. The blades are arc-shaped, and the arc segments of the multiple blades move closer to each other when rotating.

[0007] In some embodiments of the self-cleaning filter, the rotating disk is provided with a plurality of grooves, and a plurality of blades are provided in a one-to-one correspondence with the plurality of grooves. The blades are provided with protrusions corresponding to the positions of the grooves, and the protrusions extend into the grooves.

[0008] In some embodiments of the self-cleaning filter, the impeller assembly includes a wheel unit and a bracket, the wheel unit is fixedly connected to the bracket, the end of the bracket away from the wheel unit is fixedly connected to the rotating disk, the wheel unit has a mounting hole, and the torsion spring is fixedly connected to the inner wall of the mounting hole.

[0009] In some embodiments of the self-cleaning filter, the self-cleaning filter further includes a filter screen installed at one end of the pipe near the impeller assembly.

[0010] In some embodiments of the self-cleaning filter, the blades are triangular in shape, and the apex angles of the plurality of blades approach each other when rotated.

[0011] In some embodiments of the self-cleaning filter, the second unit is L-shaped.

[0012] Implementing the embodiments of this utility model will have at least the following beneficial effects: When the aforementioned self-cleaning filter is working normally, the water flow drives the impeller to rotate. The impeller's rotation causes the torsion spring to gradually store energy, simultaneously keeping the cleaning component in a closed state, reducing the filter pore size. When the filter shows signs of clogging, the water flow weakens, and the torsion spring releases its previously stored elastic potential energy, driving the cleaning component to unfold, widening the channel and allowing blockages to pass through smoothly, thus effectively preventing clogging. By adjusting the unfolding and closing state of the cleaning component in real time, the filter automatically widens the channel when a clogging tendency is detected, allowing blockages to pass through smoothly, thereby effectively preventing clogging.

[0017] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] It should be emphasized and explained that the various connection methods involved in this utility model can be arbitrary unless otherwise specified. For example, fixed connection can be achieved by bolts and nuts for detachable fixing, welding or integral molding, etc. Sliding connection can be achieved by groove-like or guide rail-like structures of various shapes, and rotating connection can be achieved by hinges, shafts, etc. Any existing method that can achieve the corresponding connection relationship is acceptable.

[0020] The following is combined Figure 1-6 The present invention provides a further explanation of a self-cleaning filter.

[0021] refer to Figures 1 to 6A self-cleaning filter includes a pipe 1, an impeller assembly 2, a torsion spring 3, and a cleaning component 4. The impeller assembly 2, torsion spring 3, and cleaning component 4 are housed within the pipe 1. The torsion spring 3 is sleeved on the shaft of the impeller assembly 2. The impeller assembly 2 is connected to the cleaning component 4 and can drive the cleaning component 4 to rotate. The cleaning component 4 is coaxially arranged with the pipe 1. The cleaning component 4 has a closed state and an open state. In both the closed and open states, the pipe 1 is open. In the closed state, the aperture of the cleaning component 4 is smaller than that in the open state. When the self-cleaning filter is not clogged, the water flow inside it can rotate the impeller assembly 2. The rotation of the impeller assembly 2 can cause the torsion spring 3 to store energy until it reaches equilibrium, and cause the cleaning component 4 to change from the open state to the closed state. When the self-cleaning filter is clogged, the torsion spring 3 releases potential energy to rotate the impeller assembly 2 and reset the cleaning component 4 from the closed state to the open state.

[0022] Understandably, when the self-cleaning filter is working normally, the water flow in pipe 1 drives the impeller to rotate. The impeller rotation causes the torsion spring 3 to gradually store energy, and simultaneously, when the cleaning component 4 is in the closed state, the filter aperture is reduced. However, when the filter shows signs of clogging, the water flow weakens, and the torsion spring 3 releases its previously stored elastic potential energy, driving the cleaning component 4 to unfold, widening the channel 44 and allowing the blockage to pass through smoothly, thus effectively preventing clogging. This adaptive adjustment mechanism not only improves filtration efficiency but also reduces the frequency of manual cleaning, greatly enhancing the filter's practicality and reliability. By adjusting the unfolded and closed states of the cleaning component 4 in real time, it automatically widens the channel 44 when a clogging trend is detected, allowing the blockage to pass through smoothly, thereby effectively preventing clogging and reducing manual intervention.

[0023] In this embodiment, the pipeline 1 includes a first unit 11 and a second unit 12. The first unit 11 and the second unit 12 have different diameters to form an annular platform 13 at the connection between the first unit 11 and the second unit 12. The cleaning component 4 is installed on the annular platform 13. The annular platform 13 utilizes the difference in pipe diameter to provide an installation position for the cleaning component 4, optimizes the spatial layout of the pipeline 1, and achieves a compact design.

[0024] refer to Figures 4 to 6In one embodiment, the cleaning component 4 includes a fixed disk 41, a rotating disk 42, and multiple blades 43. The rotating disk 42 abuts against the inner wall of the first unit 11. The rotating disk 42 and the fixed disk 41 are coaxially arranged with the pipe 1. The fixed disk 41 is fixed on the annular platform 13. Both the fixed disk 41 and the rotating disk 42 have channels 44 of the same diameter that are connected to the inside of the pipe 1. Multiple blades 43 are evenly distributed on the rotating disk 42 in the circumferential direction. Multiple blades 43 are arranged between the rotating disk 42 and the fixed disk 41. One end of the blade 43 is rotatably connected to the fixed disk 41, and the other end is rotatably connected to the rotating disk 42. The impeller assembly 2 is connected to the rotating disk 42 through a torsion spring 3. When the impeller assembly 2 rotates forward and backward, it can drive the rotating disk 42 to rotate, so that each blade 43 can rotate in a direction closer to or away from the axis of the pipe 1. The blades 43 are arc-shaped, and when they rotate, the arc segments of multiple blades 43 move closer to each other.

[0025] In this embodiment, both the fixed disk 41 and the rotating disk 42 can be annular structures, and their inner ring diameters can be the same. The fixed disk 41 can be fixedly connected to the annular platform 13 by bolts, screws, or other fasteners. The rotating disk 42 is installed in the pipe 1 through a groove on the inner wall of the first unit 11 and can rotate within the first unit 11. The rotating disk 42 is located on the side of the fixed disk 41 facing away from the annular platform 13. It can be understood that the rotating disk 42 can rotate relative to the fixed disk 41. Multiple blades 43 are placed between the rotating disk 42 and the fixed disk 41. This arrangement enables the blades 43 to be in a closed state and an expanded state. In conjunction with the torsion spring 3, the cleaning assembly 4 has a dynamic adjustment function, which can automatically expand the channel 44 when blocked, allowing the blockage to pass through smoothly, thereby effectively avoiding continuous blockage and improving the operating stability and self-cleaning ability of the filter.

[0026] In this embodiment, the rotating disk 42 is provided with multiple grooves 421, and multiple blades 43 are provided one-to-one with the multiple grooves 421. The blades 43 are provided with protrusions 431 at the positions corresponding to the grooves 421, and the protrusions 431 extend into the grooves 421. The cooperation between the grooves 421 and the protrusions 431 can stabilize the movement trajectory of the blades 43 and guide the unfolding and closing of the blades 43.

[0027] refer to Figure 2 and Figure 3 In one embodiment, the impeller assembly 2 includes a wheel unit 21 and a bracket 22. The wheel unit 21 is fixedly connected to the bracket 22. The end of the bracket 22 away from the wheel unit 21 is fixedly connected to the rotating disk 42. The wheel unit 21 has a mounting hole 221, and the torsion spring 3 is fixedly connected to the inner wall of the mounting hole 221.

[0028] In this embodiment, the rotation of the wheel unit 21 is transmitted to the rotating disk 42 through the bracket 22. The bracket 22 can be composed of a rod-shaped structure, specifically a U-shaped frame or two connecting rods. The bracket 22 is connected to the eccentric position of the rotating disk 42. The bracket 22 reduces the driving force required for the rotation of the wheel unit 21, thus achieving the labor-saving effect of the overall structure.

[0029] refer to Figure 1 and Figure 2 In one embodiment, the self-cleaning filter further includes a filter screen 5, which is installed at the end of the pipe 1 near the impeller assembly 2. By setting the filter screen 5 and installing it at the end of the pipe 1 near the impeller assembly 2, coarse particulate impurities in the water can be initially filtered.

[0030] refer to Figure 6 In one embodiment, the blade 43 is triangular in shape, and the apexes of multiple blades 43 move closer to each other during rotation. In the previous embodiment, the blade 43 was arc-shaped, while in this embodiment, the blade 43 is triangular. Of course, the shape of the blade 43 can also be other shapes without limitation, and can be selected according to the desired effect.

[0031] refer to Figure 1 In one embodiment, the second unit 12 is L-shaped. In the previous embodiments, the second unit 12 may be a straight cylindrical structure, while in this embodiment, the second unit 12 is L-shaped. The straight cylindrical and L-shaped structures can be selected to adapt to different pipes 1.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
