DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 4 As shown, a filtering device for industrial wastewater treatment includes a filtering box 1, a water inlet pipe 2 is fixedly installed on the upper surface of the filtering box 1, and a drainage pipe 3 is fixedly installed on one side of the filtering box 1;

[0024] A through groove 4 is formed on one side of the inner wall of the filter box 1, and filter plates 5 are slidably arranged in two through grooves 4. A blocking plate 6 is fixedly installed on one side of the two filter plates 5.

[0025] Two brackets 7 are fixedly installed on one side of the filter box 1, and screw rods 8 are rotatably installed between the inner walls of the two brackets 7. One side of the two screw rods 8 is threadedly provided with movable frames 9, and one side of the two movable frames 9 is fixedly connected to the corresponding blocking plates 6 respectively.

[0026] The staff discharges sewage into the filter box 1 through the water inlet pipe 2, and the sewage flows to the position of the filter plate 5, so that the filter plate 5 filters the sewage. The filtered sewage is discharged from the filter box 1 through the drain pipe 3, which is convenient for the staff to perform subsequent treatment. When it is necessary to clean the filter plate 5 for purification, the staff rotates the screw rod 8 at the top to drive the movable frame 9 to move by screwing it in, so that the filter plate 5 at the top is moved out of the filter box 1 through the corresponding through groove 4. Then the staff controls the screw rod 8 at the bottom to rotate, so that the filter plate 5 at the bottom enters the filter box 1 through the through groove 4, thereby removing the filter plate 5 with dirt accumulated on the surface from the filter box 1 without affecting the filtering work, which is convenient for the staff to clean it without affecting the filtering work and avoid affecting the sewage filtration efficiency. The process of removing the filter plate 5 is simple, which greatly reduces the workload of the staff.

[0027] In another embodiment of the utility model, one end of the two screw rods 8 passes through the corresponding bracket 7 and is sleeved with a pulley 801, and the surfaces of the two pulleys 801 are sleeved with a transmission member 10 for transmission. The thread grooves of the two screw rods 8 have opposite rotation directions.

[0028] The transmission member 10 is a transmission belt.

[0029] When the staff rotates the screw rod 8 located at the top, the pulley 801 set at one end of the rod body rotates accordingly. Under the cooperation of the two pulleys 801 and the transmission belt, the screw rod 8 located at the bottom rotates and drives the corresponding moving frame 9 to move, so that the two filter plates 5 move alternately. The staff does not need to rotate the screw rod 8 separately, which reduces the workload of the staff and improves the utilization rate of power.

[0030] In another embodiment of the utility model, a vertical plate 11 is fixedly installed on the side of the filter box 1 away from the screw rod 8, a movable groove 12 is opened on one side of the vertical plate 11, a movable block 13 is slidably arranged in the movable groove 12, a right-angle plate 14 is fixedly installed on one side of the movable block 13, a support plate 15 is movably arranged on the lower surface of the right-angle plate 14, and a brush plate 16 is fixedly installed on the lower surface of the support plate 15;

[0031] A threaded rod 1201 is rotatably mounted between the two sides of the inner wall of the moving groove 12, and the moving block 13 is threadedly arranged on one side of the rod body of the threaded rod 1201;

[0032] The upper end of the threaded rod 1201 passes through the vertical plate 11 and is fixedly mounted with a rotating wheel 1202 .

[0033] A slide groove 17 is formed through the upper surface of the right-angle plate 14 . A slider 18 is slidably disposed in the slide groove 17 . The lower surface of the slider 18 is fixedly connected to the support plate 15 .

[0034] When the filter plate 5 that needs to be cleaned is moved to the outside of the filter box 1, the staff rotates the rotating wheel 1202, so that the rotating threaded rod 1201 drives the moving block 13 and the support plate 15 to move by screwing in the thread. After the support plate 15 drives the brush plate 16 to move to the position of the filter plate 5, the staff pushes the support plate 15 to drive the brush plate 16 to move in the direction of the filter plate 5 and clean the dirt on its surface. The staff does not need to disassemble the filter plate 5 and perform subsequent processing, which further simplifies the cleaning steps of the filter plate 5.

[0035] In another embodiment of the utility model, a slide bar 19 is fixedly installed between the two sides of the inner wall of the slide groove 17, a slider 18 is slidably arranged on one side of the slide bar 19, and a spring 20 is sleeved on the other side of the slide bar 19.

[0036] When the staff pushes the support plate 15, the spring 20 is compressed. After the brush plate 16 cleans the filter plate 5, the staff no longer pushes the support plate 15. At this time, the spring 20 resets and pushes the support plate 15 to reset. The staff does not need to manually reset the support plate 15 and the brush plate 16, which further reduces the workload of the staff.

[0037] The working principle of a filtration device for industrial wastewater treatment:

[0038] When in use, the staff discharges sewage into the filter box 1 through the water inlet pipe 2, and the sewage flows to the position of the filter plate 5, so that the filter plate 5 filters the sewage, and the filtered sewage is discharged from the filter box 1 through the drain pipe 3, which is convenient for the staff to perform subsequent treatment. When it is necessary to clean the filter plate 5 for purification work, the staff rotates the screw rod 8 at the top to drive the movable frame 9 to move by screwing in the thread, so that the filter plate 5 at the top is moved out of the filter box 1 through the corresponding through groove 4. Then the staff controls the screw rod 8 at the bottom to rotate, so that the filter plate 5 at the bottom enters the filter box 1 through the through groove 4, thereby moving the filter plate 5 with dirt accumulated on the surface out of the filter box 1 without affecting the filtering work, which is convenient for the staff to clean it without affecting the filtering work, avoiding affecting the sewage filtration efficiency, and the process of removing the filter plate 5 is simple, which greatly reduces the labor of the staff.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
