[0020] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0021] The utility model provides Figure 1-4 A waste liquid pressurized filtering device shown in the figure includes a pressure tank 1, one end of which is equipped with a pressure pump 2, the output end of the pressure tank 1 is connected to an upper filter barrel 3 through a pipeline, a lower filter barrel 4 is arranged below the upper filter barrel 3, and a replaceable filter assembly 7 is arranged between the upper filter barrel 3 and the lower filter barrel 4. The outer sides of the upper filter barrel 3 and the lower filter barrel 4 are both provided with a clamping block 11 that can slide back and forth, and the outer wall of the clamping block 11 located below the upper filter barrel 3 is clamped with a replacement arm 8 that can drive it to rotate. The waste water inside the pressure tank 1 is pressurized by the pressure pump 2, so that the pressurized waste water flows into the interior of the filter barrel to achieve the filtering effect. The filtered waste water flows out through the lower filter barrel 4, and the inner wall of the clamping block 11 can be provided with a sealing structure to enhance the sealing effect of the gap so that the pressurized waste water will not flow out along the gap.

[0022] A positioning block 12 is provided on the side of the clamping block 11 away from the filter assembly 7, and a plurality of springs 13 are provided between the positioning block 12 and the clamping block 11. A telescopic assembly 18 is fixedly connected to one side of the positioning block 12, and an output end of the telescopic assembly 18 passes through the positioning block 12 and forms a detachable connection with the clamping block 11. The opening and closing of the clamping block 11 is controlled by the telescopic assembly 18 to limit and fix the filter assembly 7 to prevent the filter assembly 7 from falling off and causing the filtering effect to fail. The setting of a plurality of springs 13 ensures that the clamping block 11 can evenly clamp the annular protrusion 14 and the replacement arm 8 on the outside of the filter assembly 7. A groove for accommodating the replacement arm 8 and the annular protrusion 14 can be provided at the bottom end of the clamping block 11, thereby increasing the sealing effect and preventing wastewater from leaking.

[0023] The outer wall of the filter assembly 7 is provided with an annular protrusion 14, and the replacement arm 8 is provided with a discharge groove 9 which is adapted to the size of the annular protrusion 14. The replacement surface of the replacement arm 8 is adapted to the outer surface contour of the filter assembly 7. By matching the annular protrusion 14 with the discharge groove 9, the replacement arm 8 can drive the filter assembly 7 to move through the discharge groove 9, thereby reducing the difficulty of automatically replacing the filter assembly 7.

[0024] A storage cavity 5 is provided on one side of the lower filter barrel 4, and a replacement component 6 is provided on one side of the storage cavity 5. The replacement component 6 is provided with a groove at a height matching the filter component 7 located below the upper filter barrel 3. A plurality of replacement filter components 7 are stacked inside the replacement component 6. The two replacement arms 8 rotate on one side of the storage cavity 5. The replacement arms 8 can move the filter component 7 located inside the replacement component 6 to the bottom of the upper filter barrel 3 by rotating. The storage cavity 5 is used to accommodate fallen blocked filter components 7. The replacement component 6 is hollow, and multiple unblocked filter components 7 are stacked to facilitate direct access, thereby increasing the speed of replacement and reducing the difficulty of operation.

[0025] The rotating end of one of the replacement arms 8 is fixedly connected to an internal gear shaft 15, and the rotating end of the other replacement arm 8 is fixedly connected to an external gear shaft 16. The two replacement arms 8 are at the same height. The external gear shaft 16 is sleeved on the outside of the internal gear shaft 15. The bottom ends of the outer side walls of the external gear shaft 16 and the internal gear shaft 15 are both provided with gears. A driving gear 17 meshing with one of the gears is provided on one side of the gear. One end of the driving gear 17 is connected to a rotating motor and a telescopic motor. The driving gear 17 can be driven by the telescopic motor to rotate the internal gear shaft 15 or the external gear shaft 16, thereby achieving the purpose of controlling the rotation of a single replacement arm 8, improving the replacement speed, and reducing the maintenance difficulty.

[0026] A rotatable unloading rod 10 is provided on one side of the storage cavity 5. The height of the unloading rod 10 is adapted to the height of the unloading trough 9. The unloading rod 10 can be rotated through the unloading trough 9. During the replacement of the filter assembly 7, the replacement arm 8 and the blocked filter assembly 7 can be separated by rotating the unloading rod 10, and the filter assembly 7 can be dropped into the storage cavity 5, so that the replacement arm 8 can directly move the unblocked filter assembly 7 and reduce the difficulty of maintenance.

[0027] In the utility model, the upper filter barrel 3, the lower filter barrel 4 and the filter assembly 7 form a filter cavity, and the filter assembly 7 is clamped by the clamping block 11 to ensure the sealing effect. When the filter assembly 7 needs to be replaced due to poor filtering effect, the replacement arm 8 is driven to rotate by the active gear 17, and the replacement arm 8 drives the filter assembly 7 to move by lifting the clamping block 11. When it moves to the unloading rod 10, the unloading rod 10 rotates, and the disassembly rod knocks the filter assembly 7 into the storage cavity 5 through the unloading groove 9. The active gear 17 drives another gear to rotate, drives the filter assembly 7 located inside the replacement assembly 6 to rotate, and moves the filter assembly 7 to the bottom of the upper filter barrel 3, and clamps the filter assembly 7 by the clamping block 11, so as to achieve the purpose of replacing the filter assembly 7. The replacement process is simple and fast, which can greatly reduce the downtime and improve the maintenance efficiency of the equipment. Since the replacement process is simple, it can also reduce equipment damage and additional costs caused by incorrect operation or improper handling.
