Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically to an automatic cleaning device for filter cloths and screens. Background Technology

[0002] Modified kaolin refers to a functional mineral material that is processed through physical, chemical, or mechanical means to alter the surface properties, crystal structure, or chemical composition of natural kaolin, thereby endowing it with new functions or improving its original properties. In applications such as ceramic raw materials, pigments, and fillers, kaolin particles are refined and their surfaces activated through mechanical forces such as grinding and impact, resulting in lattice defects and new active sites. This process is not only simple and low-cost, but it can also be used in conjunction with other modification methods to improve dispersibility and reactivity.

[0003] When grinding kaolin, filter cloth or filter screen is required for sieving. After use, the filter cloth and filter screen need to be cleaned to avoid clogging of the filter pores and affecting subsequent use. However, filter screens are divided into flexible filter screens and rigid filter screens. Existing cleaning equipment can usually only clean flexible filter cloths and filter screens, or only clean rigid filter screens, which limits the scope of application and is not convenient for actual production needs.

[0012] Preferably, a sliding magnetic ring is fixedly connected to the outer surface of the slide plate, and a solid magnetic ring is fixedly connected to the inside of the slide groove. Both the sliding magnetic ring and the solid magnetic ring are sleeved on the outside of the slide rod, and the sliding magnetic ring and the solid magnetic ring interact with each other through magnetic repulsion.

[0013] Beneficial effects This invention provides an automatic cleaning device for filter cloths and screens. Compared with the prior art, it has the following advantages: (1) By setting up a double washing mechanism, the ends of the filter screen or filter cloth can be clamped by using the clamping groove and clamping plate. The flexible filter screen and filter cloth are attached to the outer surface of other vertical strips, and the vertical strips are slid in all directions by the rack to achieve the stretching and tightening effect. Alternatively, by rotating two of the vertical strips, the clamping grooves on both sides are aligned with each other to clamp the rigid filter screen. Then, the turntable is rotated by the drive motor to remove the raw material that clogs the filter holes through centrifugal force to achieve the cleaning purpose. This also improves the range of applicability to meet different cleaning needs in actual production.

[0014] (2) By setting up a tensioning component, the worm gear drives the worm wheel to rotate, and the toothed column meshes with the toothed groove and the rack respectively, thereby driving multiple racks to move in the same direction and at the same speed. This not only achieves the tensioning effect on the flexible filter screen and filter cloth, but also allows for the adjustment of the tension range to adapt to the cleaning of filter cloths and filter screens of different specifications, thereby further improving the applicability of the device.

[0015] (3) By setting up a cleaning component, the elastic extension and contraction of the spring rod can be used to allow the support plate to drive the brush roller close to the vertical bar so that when the turntable drives the flexible filter screen and filter cloth to rotate, the brush bristles of the brush roller can clean the outside of them, thereby improving the cleaning efficiency of the flexible filter screen and filter cloth. The dual effect of low-speed rotation and cleaning can ensure the cleaning effect and avoid the problem of damage to the flexible material caused by the centrifugal force generated by high-speed rotation. Furthermore, the high-speed rotation of the turntable causes the arc strip to move in all directions and the ball bearings abut against the support plate so that the brush roller moves away from the vertical bar, thereby avoiding affecting the high-speed rotation of the rigid filter screen and achieving the purpose of cleaning.

[0016] (4) By setting up an anti-wrinkle unit, the sliding plate inside the chute is made so that the needles on the sliding plate are aligned with the filter holes or installation holes of the flexible filter screen and filter cloth. Then, through the repulsive force between the sliding magnetic ring and the solid magnetic ring, the needles on the upper and lower sides are stretched and tightened on the two long sides of the flexible filter screen and filter cloth, thus avoiding the problem of the flexible filter screen and filter cloth shifting or wrinkling due to friction when in contact with the brush roller, thereby further improving the cleaning effect and cleaning efficiency of the flexible filter screen and filter cloth.

The cross-section of the retaining ring 56 is T-shaped to improve the stability of the worm wheel 51. The outer surface of the retaining ring 56 is rotatably embedded in the inside of the turntable 3.

[0024] A cleaning assembly 8 is provided on the outside of the vertical bar 7. The cleaning assembly 8 includes a support plate 81. The outer surface of the support plate 81 is slidably connected to the inside of the cleaning box 1. A brush roller 82 is rotatably connected to the outer surface of the support plate 81. The surface of the brush roller 82 is provided with bristles (not shown in the figure) to clean the surface of the flexible filter screen and filter cloth. The brush roller 82 is located on the outside of the vertical bar 7. A spring rod 84 is fixedly connected to the outer surface of the support plate 81. The spring rod 84 is made of fatigue-resistant material and controls the reciprocating sliding of the brush roller 82 through elastic extension and contraction. One end of the spring rod 84 is fixedly connected to the inside of the cleaning box 1.

[0025] The support plate 81 is provided with multiple arc strips 85 of equal size, which can be fitted together to form a ring. The outer surface of the arc strips 85 is rotatably connected to the inside of the cleaning box 1. The outer surface of the arc strips 85 is embedded with ball bearings 86, which reduce contact friction by rolling, thereby reducing wear. The outer surface of the ball bearings 86 is movably connected to the outer surface of the support plate 81. The outer surface of the arc strips 85 is fixedly connected with a slide bar 87, which slides radially along the turntable 3 to drive the arc strips 85 to push against the brush roller 82. The outer surface of the slide bar 87 is slidably connected to the outer surface of the turntable 3. The outer surface of the slide bar 87 has a through reciprocating groove 88, which is the path for the radial sliding of the slide bar 87. The reciprocating groove 88 is slidably connected to a frame 89 inside the reciprocating groove 88, which provides sliding support and limit for the slide bar 87. The outer surface of the frame 89 is fixedly connected to the outer surface of the turntable 3.

[0026] The brush roller 82 is provided with an anti-wrinkle unit 83 on its exterior. The anti-wrinkle unit 83 includes a groove 831, which is formed on the outer surface of the other vertical strips 7. The groove 831 is formed on the upper and lower sides of the outer surface of the other vertical strips 7. A slide plate 832 is slidably connected inside the groove 831.

Both the sliding magnetic ring 835 and the solid magnetic ring 836 are made of permanent magnets, and the repulsive force between them is greater than the friction force applied by the brush roller 82 to the flexible filter screen and filter cloth, so as to avoid the problem of wrinkles in the flexible filter screen and filter cloth affecting the cleaning effect and efficiency. The sliding magnetic ring 835 and the solid magnetic ring 836 are both sleeved on the outside of the slide rod 834, and the sliding magnetic ring 835 and the solid magnetic ring 836 interact with each other through magnetic repulsion.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working principle: First, put the filter cloth or filter screen to be cleaned into the cleaning box 1. Then, when cleaning the flexible filter screen and filter cloth, rotate two of the vertical bars 7 so that the clamping grooves 10 face outward and move away from each other. When cleaning the rigid filter screen, rotate two of the vertical bars 7 so that the clamping grooves 10 face each other. When cleaning the rigid filter screen; adjust the motor 55 to drive the worm 54 to rotate. Through the meshing of the worm 54 and worm wheel 51, and the meshing of the toothed column 53 with the toothed groove 52 and the rack 4, the rack 4 slides outward through the through groove 6, so that the distance between the two clamping grooves 10 is greater than the length of the filter screen. Then, place both ends of the rigid filter screen inside the two clamping grooves 10, and between the two clamping plates 12 inside the clamping grooves 10. Then, hold the exposed end of the screw 13, and improve the stability of holding it through the anti-slip texture 14. Then rotate the screw 13 and connect it with the two clamping plates 12 through the thread, so that the two clamping plates 12 move closer to each other to clamp the ends of the rigid filter screen. During the movement of the clamping plates 12, the fixing rod 1 1. The drive motor 2 serves as a motion guide and limiting support. After the rigid filter screen is clamped, the drive motor 2 drives the turntable 3 to rotate, which causes the rack 4 to drive the rigid filter screen to rotate rapidly through two vertical bars 7. Through the action of centrifugal force, the modified kaolin material that is blocked inside the filter pores is thrown off. Since the centrifugal force is greater than the effect of the spring rod 84, one end of the slide bar 87 drives the arc bar 85 to slide outward. During this process, the fixed frame 89 limits the sliding of the slide bar 87 through the reciprocating groove 88. After the arc bar 85 moves, it abuts against the support plate 81 through the ball bearing 86, so that the support plate 81 compresses the spring rod 84, thereby moving the brush roller 82 away from the vertical bars 7 to avoid affecting the cleaning effect and efficiency of the rigid filter screen. When cleaning filter cloth or flexible filter screen: First, rotate two of the vertical strips 7 so that the grooves 10 on their surfaces are facing away from each other. Then, clamp the filter cloth inside one side of the groove 10 using the corresponding clamping plate 12. Next, driven by the worm 54 and worm wheel 51, the rack 4 drives the vertical strip 7 to slide in four directions, so that half of the stretching range of the vertical strip 7 is adapted to the size of the filter cloth. Then, stretch the other end of the filter cloth so that it fits tightly against the surface of the remaining vertical strips 7. Then, slide the slide plate 832 inside the slide groove 831 so that the needle 833 is inserted into the filter hole or its mounting hole of the filter cloth. Then, the magnetic ring 8... The repulsive force between the filter cloth and the magnetic ring 836 makes the upper and lower sides of the filter cloth also tensile and taut. Then, the other end of the filter cloth is placed in the clamping groove 10 on the other side for clamping, thereby achieving complete tension and fixation of the filter cloth. Then, the drive motor 2 drives the filter cloth to rotate through the turntable 3, rack 4 and vertical bar 7. The centrifugal force generated by the rotation is less than the elastic force of the spring rod 84. On the one hand, it avoids the problem of filter cloth damage caused by excessive centrifugal force. On the other hand, it makes the bristles of the brush roller 82 contact the surface of the filter cloth. Thus, during the rotation of the filter cloth, the modified kaolin raw material on its surface is cleaned by the bristles to improve the cleaning efficiency and effect. During the cleaning process of filter cloth or filter screen, cleaning solution can be added inside the cleaning tank 1 according to the actual cleaning and recycling needs, as well as the performance of modified kaolin, to further improve the cleaning efficiency and effect. For example, a combination of surfactant and warm water can be set inside the cleaning tank 1, which can not only achieve the cleaning effect, but also recycle the clogged organic modified kaolin.
