DETAILED DESCRIPTION
[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] A kind of cleaning mechanism for stainless steel filter element, please refer to Figure 1 As shown, the main structure is formed by the support plate, and a cleaning member 1 is arranged above the support plate, and the stainless steel filter screen 2 is properly placed below the cleaning member 1.
[0025] Specifically, the cleaning member 1 should include a cleaning head and its matching drive pipe. The internal cavity of the drive pipe is in communication with the internal cavity of the cleaning head, and the cleaning head is provided with a corresponding through hole to spray water outward, thereby effectively cleaning the inner wall of the stainless steel filter screen 2.
[0026] In addition, the device is additionally provided with two support components, which are symmetrically arranged on both sides of the support plate. By applying a certain pressing force to the stainless steel filter screen 2 through the two support components, the stainless steel filter screen 2 can be stably positioned.
[0027] Please refer to Figure 1 and Figure 2 As shown, compared with the prior art, each support member 3 in the present scheme is designed to include two follow-up shafts 304, which are arranged in parallel along the left and right axes, and the two follow-up shafts 304 are arranged from top to bottom. In actual application, by alternately changing the follow-up shaft 304 that applies a pressing force to the stainless steel filter screen 2, the dynamic adjustment of the contact point position of the device and the stainless steel filter screen 2 can be realized. This design utilizes the diversification of the contact position to ensure that the contact point is not at the same level as the cleaning head, thereby ensuring that the liquid sprayed by the cleaning head can effectively flush the blocked impurities in the filter holes of the stainless steel filter screen 2, thereby improving the overall cleaning efficiency.
[0028] Specifically, at the end of the two support members 3 away from the center, one drive shaft 308 is arranged along the left and right axes. The middle part of each drive shaft 308 is connected to a positioning rod 309 by a rotating connection, and the positioning rod 309 is fixedly connected to the support plate.
[0029] Meanwhile, inside each support member 3, two follower shafts 304 are jointly provided with a driven rod 307 along the up-down axial direction, which is fixedly connected with a corresponding driving shaft 308. At this time, by constraining the two axial ends of each driven rod 307 to form a movable connection with the corresponding two follower shafts 304, when the driving shaft 308 swings up and down around the positioning rod 309, the up-down position of the driven rod 307 can be changed, thereby realizing the precise adjustment of the horizontal position of the follower shaft 304.
[0030] It should be noted that when the central axis of each driving shaft 308 is perpendicular to the vertical plane, the plurality of follower shafts 304 will be in contact with the stainless steel filter screen 2, which ensures that there is always a follower shaft 304 inside the single support member 3 that is in contact with the stainless steel filter screen 2 and that there is always a follower shaft 304 that exerts a stable limiting effect on the stainless steel filter screen 2.
[0031] Further, the device is fixedly connected with a contact ring plate 302 at one end of each follower shaft 304 close to the stainless steel filter screen 2, and each contact ring plate 302 is further fixedly connected with a damping pad 301 made of rubber at one end close to the stainless steel filter screen 2. This is designed to effectively prevent the support member 3 from hard contact with the stainless steel filter screen 2, thereby avoiding deformation of the stainless steel filter screen 2, by utilizing the deformable property of the rubber material of the damping pad 301.
[0032] Meanwhile, a damping groove 313 is provided through each damping pad 301 to enhance the frictional resistance between the support member 3 and the stainless steel filter screen 2. In actual application, to avoid the single follower shaft 304 moving too far towards the stainless steel filter screen 2 due to the swinging of the driving shaft 308, thereby causing the damping pad 301 to exert too much pressure on the stainless steel filter screen 2 and causing irreversible deformation of the stainless steel filter screen 2, the device is usually designed so that when the central axis of the driving shaft 308 is perpendicular to the vertical plane, the plurality of follower shafts 304 are in abutment with the stainless steel filter screen 2, rather than the plurality of follower shafts 304 exerting too much pressure on the stainless steel filter screen 2. This ensures that when the central axis of the driving shaft 308 is perpendicular to the vertical plane, the pressure on the stainless steel filter screen 2 is minimized, thereby effectively preventing the follower shaft 304 from moving too far towards the stainless steel filter screen 2 and causing irreversible deformation.
[0033] Therefore, to ensure that the stainless steel filter screen 2 does not shift in position when the central axis of the driving shaft 308 is perpendicular to the vertical plane, the device increases the frictional resistance between the damping pad 301 and the stainless steel filter screen 2, so that the damping pad 301 can realize the position constraint of the stainless steel filter screen 2 solely relying on the frictional resistance.
[0034] Further, the device stipulates that the angle between the central axis of each driven rod 307 and the vertical plane must be kept between 0° and 10°. In other words, during actual operation, even if the driving shaft 308 swings to the top of its end movement stroke, the angle between the central axis of the driven rod 307 and the vertical plane must not exceed 10°. This design aims to strictly limit the stroke of the single follower shaft 304 moving towards the stainless steel filter screen 2, ensuring that the stroke is relatively short.
[0035] Further, the device is configured with a cooperating piece 305 on the outer side of each follower shaft 304, which realizes a sliding connection with the corresponding follower shaft 304. The two axial ends of each driven rod 307 are respectively in movable connection with the corresponding cooperating piece 305.
[0036] Meanwhile, please refer to Figure 3 The two axial ends of each cooperating piece 305 are respectively in contact with the corresponding driven rod 307 and the baffle. This design ensures that when the driven rod 307 drives the follower shaft 304 to move towards the stainless steel filter screen 2, the reaction force generated by the stainless steel filter screen 2 against the deformation of the damping pad 301 can further promote the soft contact between the damping pad 301 and the stainless steel filter screen 2 through the compression of the compression spring 303, thereby effectively avoiding irreversible deformation of the stainless steel filter screen 2.
[0037] Therefore, when the central axis of each driving shaft 308 is perpendicular to the vertical plane, the compression spring 303 corresponding to the driving shaft 308 will not accumulate elastic potential energy. At this time, the plurality of damping pads 301 are only in contact with the stainless steel filter screen 2 and realize the constraint of the position of the stainless steel filter screen 2 through the frictional resistance.
[0038] Specifically, each driven rod 307 is fixedly connected with a limiting ring 306 at the end away from the stainless steel filter screen 2, and the cooperating piece 305 is placed between the limiting ring 306 and the baffle. Under this configuration, the driven rod 307 can effectively drive the cooperating piece 305, thereby causing the follower shaft 304 to move away from the stainless steel filter screen 2.
[0039] Further, the lower end of each fitting 305 is designed with a specific accommodating groove, into which the axial end of the driven rod 307 is inserted and firmly connected, so as to realize the rotating connection mechanism with the fitting 305. This precise design ensures that when the driven shaft 304 moves towards the stainless steel filter screen 2, the damping pad 301 can automatically and tightly adhere to the surface of the stainless steel filter screen 2, thereby maximizing the contact area between the damping pad 301 and the stainless steel filter screen 2. In this way, only the frictional resistance generated between the damping pad 301 and the stainless steel filter screen 2 can effectively stabilize and constrain the position of the stainless steel filter screen 2.
[0040] Further, as shown in Figure 4 Each accommodating groove is fixedly connected with a damping ring 314, which forms a damping connection with the driven rod 307. This design aims to prevent the damping pad 301 from continuing to adhere to the surface of the stainless steel filter screen 2 due to gravity during the movement of the driven shaft 304 away from the stainless steel filter screen 2. In actual operation, the driven rod 307 drives the driven shaft 304 to move away from the stainless steel filter screen 2 through the fitting 305, at which time the angle between the driven shaft 304 and the horizontal plane gradually increases, and the damping pad 301 tilts and moves away from the stainless steel filter screen 2 along with the driven shaft 304.
[0041] It should be particularly pointed out that the offset angle of the central axis of the driven rod 307 is relatively small under the driving of the driven rod 307. Therefore, according to the inherent characteristics of the circular structure, during the position offset of the driven shaft 304 following the driven rod 307, the driven shaft 304 mainly presents a horizontal position offset. Similarly, since the driven rod 307 and the driven shaft 304 maintain a vertical relationship, during the position offset of the driven shaft 304 following the driven rod 307, the offset angle of the central axis of the driven shaft 304 also remains within a small range. In this case, the upper and lower ends of the damping pad 301 are still approximately in the same vertical plane, so as to fully utilize the damping effect between the damping ring 314 and the driven rod 307, and realize smooth separation from the stainless steel filter screen 2.
[0042] Specifically, referring to Figure 2The device is equipped with a driving motor 312 at the end of each driving shaft 308 away from the stainless steel filter screen 2, and the driving motors 312 inside the two support members 3 keep synchronous operation. An eccentric driving rod 310 is fixedly connected to the output shaft of each driving motor 312. A transmission rod 311 is arranged between the driving rod 310 and the driving shaft 308, and the two ends of the transmission rod 311 are rotationally connected with the corresponding driving shaft 308 and driving rod 310. In addition, each transmission rod 311 is located on the side of the corresponding positioning rod 309 away from the stainless steel filter screen 2. Through the cooperation of the driving rod 310 and the transmission rod 311, the continuous up-down swing of the driving shaft 308 is realized, so that the two driven shafts 304 inside the single support member 3 can alternately apply pressure to the stainless steel filter screen 2.
[0043] Further, the distance between each transmission rod 311 and the corresponding positioning rod 309 is constrained to be smaller than the distance between each driven rod 307 and the corresponding positioning rod 309. This measure effectively reduces the power demand of the driving motor 312 by changing the length of the force arm, ensuring that the device belongs to the category of energy-saving and efficient products.
[0044] In the actual application process of the device:
[0045] Firstly, the corresponding cleaning member 1 is started, so that the cleaning nozzle inside the cleaning member 1 continuously sprays water column and simultaneously realizes the moving effect of the cleaning nozzle downward;
[0046] Subsequently, with the downward movement of the cleaning nozzle, it gradually immerses into the stainless steel filter screen 2 and starts to clean the stainless steel filter screen 2;
[0047] Then, the two driving motors 312 are started, and the driving shaft 308 starts to swing up and down continuously. In this process, when the cleaning nozzle moves to the upper region of the stainless steel filter screen 2, the upper ends of the two driven rods 307 move away from the stainless steel filter screen 2; when the cleaning nozzle moves to the middle region of the stainless steel filter screen 2, the two driven rods 307 are reversely reset; and when the cleaning nozzle moves to the upper region of the stainless steel filter screen 2 again, the lower ends of the two driven rods 307 move away from the stainless steel filter screen 2;
[0048] Finally, the cleaning nozzle continuously performs linear reciprocating motion inside the stainless steel filter screen 2, realizing reciprocating and circulating cleaning. In this process, the damping pad 301 at the same horizontal position as the cleaning nozzle always keeps a non-contact state with the stainless steel filter screen 2.
[0049] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
