[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] In the electrolytic aluminum industry, the filter cloth of the vacuum belt dehydrator is very likely to retain some fine sulfide particles or other impurities, affecting the desulfurization efficiency. To address this problem, an embodiment of the present application proposes a filter cloth cleaning device for a vacuum belt dehydrator.

[0031] See also Figure 1 , Figure 1The present invention is a schematic structural diagram of a vacuum belt dehydrator 1 and a filter cloth cleaning device 2 according to an embodiment of the present invention. In one embodiment of the present invention, the vacuum belt dehydrator 1 includes an endless rubber belt 10, a vacuum box 20, a filter cloth 30, a discharge roller 40, and a filter cloth tensioning mechanism 50. Specifically, the vacuum box 20 is arranged on the relatively inner side of the endless rubber belt 10, the discharge roller 40 is arranged on one side of the endless rubber belt 10, and the filter cloth tensioning mechanism 50 is arranged at intervals on the circumference of the endless rubber belt 10. The filter cloth 30 is sleeved on the endless rubber belt 10, the discharge roller 40, and the filter cloth tensioning mechanism 50, wherein at least part of the filter cloth 30 is laid on the endless rubber belt 10, and is adsorbed on the endless rubber belt 10 by the suction action of the vacuum box 20, and continuously operates with the transmission of the endless rubber belt 10.

[0032] In the vacuum belt dehydrator 1, the slurry is evenly distributed on the filter cloth 30. When the vacuum box 20 is connected to the vacuum system, a vacuum filtration area is formed at the corresponding position of the annular rubber belt 10. The filtrate in the slurry is filtered into the vacuum chamber, and the solid particles are trapped on the filter cloth 30 to form a filter cake. After the filter cloth 30 is separated from the annular rubber belt 10, the filter cake is discharged at the discharge roller 40. Therefore, in order to clean the filter cloth 30 after discharge, in the embodiment of the present application, the filter cloth cleaning device 2 is arranged in the lower area of ​​the filter cloth 30 after passing the discharge roller 40.

[0033] The filter cloth cleaning device 2 of the embodiment of the present application is not limited to being used on the vacuum belt dehydrator 1 described in the drawings, but can also be arranged on vacuum belt dehydrators 1 of other structures.

[0034] See also Figure 2 , Figure 2 Detailed description is a cross-sectional schematic diagram of a filter cloth cleaning device 2 according to an embodiment of the present application. The filter cloth cleaning device 2 according to an embodiment of the present application includes a mounting shell 60 , a spray mechanism 70 , a brushing mechanism 80 and a scraper mechanism 90 .

[0035] See also Figure 1-Figure 2 In one embodiment of the present application, the installation housing 60 is disposed in the area below the filter cloth 30 after passing through the discharge roller 40. In a specific implementation, the installation housing 60 can be fixedly connected to the frame of the vacuum belt dehydrator 1, or can be fixedly disposed on the ground. The top of the installation housing 60 is open, and an installation cavity is formed inside the installation housing, and the installation cavity is used to install the spray mechanism 70, the brushing mechanism 80, and the scraper mechanism 90.

[0036] Furthermore, in the embodiment of the present application, the bottom of the mounting housing 60 has a leaking hole 600 connected to the mounting cavity. The cleaning waste liquid generated by the spraying mechanism 70, the brushing mechanism 80 and the scraper mechanism 90 is collected in the mounting cavity and discharged from the filter cloth cleaning device 2 through the leaking hole 600.

[0037] The spray mechanism 70 includes a spray nozzle 71, and the spray nozzle 71 is at least partially disposed in the mounting housing 60. Specifically, the spray nozzle 71 is disposed on the inner wall of the mounting housing 60. In the embodiment of the present application, the spray nozzle 71 can be completely accommodated in the mounting housing 60, or can be partially extended out of the mounting housing 60, so as to spray and rinse the filter cloth 30 at a close distance.

[0038] In order to increase the flushing area and improve the impact efficiency, a plurality of spray nozzles 71 are provided, and the plurality of spray nozzles 71 are arranged at intervals on the inner wall of the mounting housing 60 along the width direction of the filter cloth 30. Thus, the plurality of spray nozzles 71 can cover the entire width of the filter cloth 30, so as to comprehensively and effectively flush the filter cloth 30. The spray nozzles 71 can flush away some impurities on the filter cloth 30, and can also help soften the residues dried on the filter cloth 30.

[0039] In order to enable the spray nozzles 71 to spray and rinse the filter cloth 30 smoothly, the plurality of spray nozzles 71 are arranged at an angle to the filter cloth 30. Preferably, the spray directions of the plurality of spray nozzles 71 are perpendicular to the surface of the filter cloth 30.

[0040] In one embodiment of the present application, the brushing mechanism 80 is at least partially disposed in the mounting housing 60. Figure 2 The brushing mechanism 80 includes a brushing assembly 81, an angle adjustment assembly 82 and a position adjustment assembly 83. The brushing assembly 81 is used to brush the filter cloth 30, the angle adjustment assembly 82 is used to adjust the relative angle between the brushing assembly 81 and the filter cloth 30, and the position adjustment assembly 83 is used to adjust the relative distance between the brushing assembly 81 and the filter cloth 30.

[0041] See also Figure 3 , Figure 3 The present invention is a schematic diagram of the structure of a scrubbing mechanism 80 according to an embodiment of the present application. Specifically, the scrubbing assembly 81 includes a scrubbing chassis 811, a cleaning brush 812, and a first driving member 813. The cleaning brush 812 is connected to the scrubbing chassis 811, and the first driving member 813 is arranged on the side of the scrubbing chassis 811 away from the cleaning brush 812, wherein the scrubbing chassis 811 is configured to rotate around its own rotation center, and the first driving member 813 can drive the scrubbing chassis 811 to rotate, thereby driving the cleaning brush 812 to rotate. Thus, the cleaning brush 812 can rotate to scrub the filter cloth 30, and effectively remove the residue on the filter cloth 30 after being softened by spraying. In the embodiment of the present application, the first driving member 813 can be a motor, or other types of drivers.

[0042] In order to allow the brushing components 81 to fully cover the filter cloth 30 and ensure that it is thoroughly cleaned, multiple brushing components 81 are set in the embodiment of the present application. If multiple brushing components 81 are arranged at intervals along the width direction of the filter cloth 30, there may be areas that cannot be cleaned at the boundaries of adjacent brushing components 81, which will cause insufficient cleaning of certain areas of the filter cloth 30. Therefore, in a preferred embodiment of the present application, a layout method in which the brushing components 81 are staggered along the width direction of the filter cloth 30 is adopted. This staggered arrangement not only ensures that the entire width direction of the filter cloth 30 can be effectively cleaned, but also avoids cleaning blind spots or dead corners, making the cleaning work more comprehensive and meticulous.

[0043] It should be noted that during the operation of the vacuum belt dewatering machine 1, the position and tension of the filter cloth tensioning mechanism 50 play a decisive role in the position and angle of the filter cloth 30. First, the positions of the filter cloth tensioning mechanisms 50 in different vacuum belt dewatering machines 1 are different. This difference in position leads to the diversity of the position and angle of the filter cloth 30 set on the filter cloth tensioning mechanism 50. Secondly, the difference in the tension of the filter cloth tensioning mechanism 50 in the vacuum belt dewatering machine 1 will not only lead to changes in the tightness of the filter cloth 30, but also may cause changes in the position and angle of the filter cloth 30. Therefore, in the actual production process, the filter cloth 30 set on the filter cloth tensioning mechanism 50 may have different heights and lateral positions, and its inclination angle may also be different. This change in position and angle makes it difficult for the fixed filter cloth cleaning device to accurately align the filter cloth 30 for cleaning.

[0044] Therefore, in order to adapt to the position and angle changes of the filter cloth 30 and improve the cleaning effect, the brushing component 81 in the embodiment of the present application can adjust the relative angle and relative position with the filter cloth 30 to ensure that the brushing component 81 always maintains the best contact state with the surface of the filter cloth 30.

[0045] In order to ensure that the cleaning brush 812 can fully contact the surface of the filter cloth 30 , the filter cloth cleaning device 2 of the embodiment of the present application uses an angle adjustment component 82 to adjust the relative angle between the cleaning brush 812 and the brushing component 81 and the filter cloth 30 .

[0046] See also Figure 3-Figure 4 , Figure 4The cross-sectional schematic diagram of an angle adjustment assembly 82 of an embodiment of the present application, in an embodiment of the present application, the angle adjustment assembly 82 is arranged in the mounting housing 60, and the angle adjustment assembly 82 is connected to the scrubbing assembly 81. The angle adjustment assembly 82 includes an adjustment housing 821, a first connecting member 822, a second connecting member 823 and a second driving member 824. In the width direction of the filter cloth 30, the adjustment housing 821 is arranged on opposite sides of the mounting housing 60. The two ends of the first connecting member 822 are respectively fixedly connected in an adjustment housing 821, the first connecting member 822 has a first connecting portion, and the first driving member 813 has a first rotating portion 8131 away from the scrubbing chassis 811, and the first rotating portion 8131 is rotatably connected to the first connecting portion. The second connecting member 823 is arranged along the width direction of the filter cloth 30, the second connecting member 823 has a second connecting portion, the first driving member 813 has a second rotating portion 8132 close to the scrubbing chassis 811, and the second rotating portion 8132 is rotatably connected to the second connecting portion.

[0047] Considering that the second driving member 824 may be damaged due to the water soaking during the cleaning process, the second driving member 824 is arranged in the adjustment housing 821 and is also arranged on the opposite sides of the mounting housing 60 to prevent the water of the brush assembly 81 from dripping onto the second driving member 824 during the cleaning process and causing erosion. The first end of the second driving member 824 is rotatably connected to the adjustment housing 821, and the second end is rotatably connected to the second connecting member 823. The second end of the second driving member 824 can move relative to its second end, thereby driving the second connecting member 823 to rotate around the axis of the first rotating portion 8131, thereby driving the first driving member 813 and the brush assembly 81 to rotate relative to the axis of the first rotating portion 8131, so as to adjust the relative angle between the brush assembly 81 and the filter cloth 30.

[0048] In specific implementation, in order to ensure that the scrubbing chassis 811 can contact and effectively scrub the filter cloth 30 with the largest area, relevant technicians need to finely adjust the second driving member 824: by adjusting the distance that the second end of the second driving member 824 moves / extends relative to the first end, the scrubbing chassis 811 is kept parallel to the filter cloth 30. This adjustment of the parallel state is very important, as it not only ensures that the scrubbing area of ​​the scrubbing chassis 811 is maximized, but also improves the cleaning effect and avoids unnecessary damage to the filter cloth.

[0049] In the embodiment of the present application, the second driving member 824 can be any one of a hydraulic push rod, an electric push rod, and an oil cylinder to achieve accurate and smooth adjustment of the relative angle between the scrubbing chassis 811 and the filter cloth 30.

[0050] Further, the position adjustment assembly 83 is disposed in the mounting housing 60, and the position adjustment assembly 83 is connected to the angle adjustment assembly 82. In the embodiment of the present application, the position adjustment assembly 83 is used to adjust the relative position between the scrubbing chassis 811 and the filter cloth 30 to ensure that the scrubbing chassis 811 can maintain continuous contact with the filter cloth 30.

[0051] Specifically, the position adjustment component 83 adopts a screw-nut transmission structure. The position adjustment component 83 includes a screw 831, a nut 832 and a third driving member 833. Among them, the screw 831 is vertically arranged on the opposite sides of the mounting housing, the nut 832 is fixedly connected to the adjustment housing 821, and the nut 832 is installed on the screw 831. The third driving member 833 is connected to the screw 831, and the third driving member 833 can drive the screw 831 to rotate, and then the nut 832, the angle adjustment component 82 and the scrubbing component 81 are in the vertical position. Thus, in the position adjustment component 83, the screw-nut transmission structure enables the relative position between the scrubbing chassis 811 and the filter cloth 30 to be accurately adjusted, ensuring that the two can maintain continuous contact, thereby improving the cleaning effect.

[0052] See also Figure 5 , Figure 5 This is an enlarged schematic diagram of a scraper mechanism 90 of an embodiment of the present application. In an embodiment of the present application, the scraper mechanism 90 is at least partially disposed in the mounting housing 60, and the scraper mechanism 90 includes a scraper body 91, a support plate 92 connected to the scraper body 91, a third rotating portion 93 connected to the support plate 92, and an elastic member 94. A fourth rotating portion 61 is disposed on the inner wall of the mounting housing 60, and the third rotating portion 93 is rotatably connected to the fourth rotating portion 61, so that the scraper body 91 can be relatively rotatably connected to the inner wall of the mounting housing 60, thereby, the scraper body 91 can flexibly adjust the angle and position during operation to meet the cleaning requirements of the filter cloth 30 with different installation angles.

[0053] Further, one end of the elastic member 94 is connected to the inner wall of the mounting housing 60, and the other end is connected to the support plate 92. In the embodiment of the present application, the elastic member 94 continuously applies elastic force to the support plate 92 so that the scraper body 91 remains in contact with the filter cloth 30. In the embodiment of the present application, the elastic member 94 can be a spring.

[0054] It should be noted that in the embodiment of the present application, the scraper body 91 is made of a soft material. When the scraper body 91 is fitted with the filter cloth 30 at an angle, it can closely contact the surface of the filter cloth 30 and be used to scrape off impurities remaining on the filter cloth 30.
