[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 、 Figure 2 , the present utility model provides a technical solution: a centrifugal separation device for chemical sewage treatment, including: a first treatment tank 1 and a water outlet pipe 9, a water inlet pipe 2 is installed at the top of the first treatment tank 1, a filter screen 3 is installed inside the first treatment tank 1, one side of the first treatment tank 1 is connected to a second treatment tank 4 through a water pump and a pipeline, a driving motor 5 is installed at the top of the second treatment tank 4, the bottom of the driving motor 5 is connected to a rotating shaft 6 passing through the second treatment tank 4, a filter barrel 7 is installed on the outer side of the rotating shaft 6 through a connecting frame, one side of the second treatment tank 4 is connected to a third treatment tank 8 through a water pump and a pipeline, and the water outlet pipe 9 is installed on one side of the third treatment tank 8;

[0025] A transmission belt 10 is connected to the outside of the rotating shaft 6 through a pulley. One end of the transmission belt 10 away from the rotating shaft 6 is connected to a driven shaft 11 through a pulley. A gear set 12 is connected to the middle of the driven shaft 11. A transmission shaft 13 runs through the middle of the gear set 12. A cleaning brush roller 14 is installed on the outside of the transmission shaft 13. A bottom plate 15 is installed at the bottom of the filter barrel 7. A first fixing block 16 is installed at the bottom of the bottom plate 15. A clamping rod 17 runs through one side of the first fixing block 16. One side of the clamping rod 17 is connected to a telescopic rod 18 that runs through the first fixing block 16. A movable spring 19 is installed between the telescopic rod 18 and the first fixing block 16. One end of the clamping rod 17 is sleeved with a second fixing block 20, and the second fixing block 20 is installed at the bottom of the filter barrel 7.

[0026] During specific implementation, for the centrifugal separation equipment used for chemical sewage treatment, when it is necessary to clean the filter barrel 7, the drive motor 5 can be started. The drive motor 5 will drive the rotating shaft 6 at the bottom to rotate. The rotation of the rotating shaft 6 will drive the filter barrel 7 to rotate. A transmission belt 10 is sleeved on the outside of the rotating shaft 6 through a pulley. The other end of the transmission belt 10 is connected to the driven shaft 11 through a pulley. With the cooperation of the pulley and the transmission belt 10, the rotating shaft 6 can drive the driven shaft 11 to rotate. A gear set 12 is installed on the outside of the driven shaft 11. The gear set 12 is connected by two meshing gears. One gear is connected to the driven shaft 11, and the other gear is connected to the transmission shaft 13. Therefore, the rotation of the driven shaft 11 will drive the transmission shaft 13 to rotate through the gear set 12. And due to the cooperation of the gear set 12, the rotation directions of the driven shaft 11 and the transmission shaft 13 are opposite. The rotation of the transmission shaft 13 will drive the cleaning brush roller 14 to rotate. Since the rotation directions of the filter barrel 7 and the cleaning brush roller 14 are opposite, the filter barrel 7 can be cleaned by the cleaning brush roller 14;

[0027] The cleaned impurities will fall onto the bottom plate 15. At this time, the maintenance baffle on one side of the second treatment tank 4 can be opened. The maintenance baffle and the second treatment tank 4 are sealed by means of a rubber sealing ring, so that the sealing effect of the second treatment tank 4 is better. Push the telescopic rod 18 at one end of the first fixing block 16 into the inside of the first fixing block 16, so that the telescopic rod 18 drives the clamping rod 17 to move to one side. The clamping rod 17 will move along the through hole of the second fixing block 20 to the notch of the through hole. At this time, the second fixing block 20 does not limit the clamping rod 17. Then the bottom plate 15 can be quickly disassembled from the bottom of the filter barrel 7, which is convenient for collecting and cleaning the impurities. Similarly, after docking the bottom plate 15 to the bottom of the filter barrel 7, make the clamping rod 17 move into the through hole of the second fixing block 20, and then release the telescopic rod 18. The telescopic rod 18 will reset through the movable spring 19, thereby driving the clamping rod 17 to move into the through hole of the second fixing block 20, which is convenient for the user to fix the bottom plate 15.

[0028] Refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 6 It can be known that during use, the cleaning brush roller 14 can be driven to rotate through the transmission shaft 13 according to the use, and the cleaning brush roller 14 can clean the filter barrel 7. At the same time, the bottom plate 15 is detached from the bottom of the filter barrel 7, so as to facilitate the collection of impurities and ensure that the filtering effect of the filter barrel 7 will not be affected.

[0029] A screw rod 21 is connected through the top of the first treatment tank 1. A nut sleeve 22 is sleeved on the outer side of the screw rod 21. A trapezoidal block 23 is installed on one side of the nut sleeve 22. A wedge block 24 is arranged on one side of the trapezoidal block 23. One end of the filter screen 3 is sleeved with a connecting block 25. A return spring 26 is installed between the filter screen 3 and the groove of the connecting block 25. Two groups of wedge blocks 24 are symmetrically arranged with respect to the trapezoidal block 23, and the connecting block 25 is installed on the inner wall of the first treatment tank 1.

[0030] During specific implementation, for the centrifugal separation equipment for chemical sewage treatment, when it is necessary to adjust the filtering effect of the filter screen 3, the screw rod 21 can be rotated. A nut sleeve 22 is sleeved on the outer side of the screw rod 21, and one side of the nut sleeve 22 is slidably connected in the groove of the first treatment tank 1. Therefore, when the screw rod 21 rotates, it will drive the nut sleeve 22 to slide. A trapezoidal block 23 is installed on the other side of the nut sleeve 22. Wedge blocks 24 are arranged on both sides of the trapezoidal block 23 through inclined surfaces. When the nut sleeve 22 drives the trapezoidal block 23 to move downward, it will squeeze the filter screen 3 at the bottom through the trapezoidal block 23 and the wedge block 24, so that the filter screen 3 at the bottom shrinks into the groove of the connecting block 25 and squeezes the return spring 26 in the groove. At the same time, the trapezoidal block 23 does not act on the wedge block 24 at the top, and then the filter screen 3 at the top will be reset through the return spring 26 in the groove of the connecting block 25, thereby driving the filter screen 3 at the top to move in the opposite direction. By moving the two groups of filter screens 3 in different directions, the sieve holes between the two groups of filter screens 3 can be misaligned, so that the filtering effect can be adjusted to meet the different use requirements of users.

[0031] Refer to Figure 2 and Figure 3 It can be known that during use, according to the impurities in the chemical wastewater, the screw rod 21 can be rotated, so that the screw rod 21 drives the two groups of filter screens 3 to move in different directions through the nut sleeve 22 and the trapezoidal block 23, thereby adjusting the filtering effect of the filter screen 3.

[0032] In summary: When the centrifugal separation device for chemical sewage treatment is in use, chemical sewage can be conveyed into the first treatment tank 1 through the water inlet pipe 2. Large-particle impurities can be filtered through the filter screen 3 in the first treatment tank 1. After the filtration is completed, the water is drained into the second treatment tank 4 through a water pump and a water pipe, and the driving motor 5 is started. The driving motor 5 will drive the filter barrel 7 to rotate through the rotating shaft 6. Relying on the action of centrifugal force, impurities can be filtered better. Then the water is drained into the third treatment tank 8 through a water pump and a water pipe, and a flocculant is added into the third treatment tank 8, so that the impurities are more likely to aggregate together and then precipitate. Finally, the treated sewage can be discharged from the third treatment tank 8 through the water outlet pipe 9, thus completing the entire chemical sewage treatment work. This is the usage feature of the centrifugal separation device for chemical sewage treatment. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0033] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
