[0059] An outer shell 1 is rotatably connected to an inner shell 3 in the outer shell 1, a plurality of drain pipes 4 are fixedly connected to the bottom of the inner shell 3 in an array, a sealing block 6 is slidably connected to the drain pipe 4, the sealing block 6 is slidably connected to the bottom of the inner shell 3, a first spring 7 is fixedly connected to the end of the sealing block 6, and a pressing block 8 is fixedly connected to the end of the first spring 7;

[0063] A rotation drive mechanism, which is used to drive the inner shell 3 to rotate;

[0064] A second pushing mechanism, the second pushing mechanism is used to push the filter block 10 to move;

[0065] It also includes a water inlet pipe 2, the top end of which penetrates the outer shell 1 and is rotatably connected to the inner shell 3;

[0066] Specifically, in the prior art, since impurities precipitated from wastewater after standing usually appear in the form of flocs, there is a large amount of wastewater therein, so when the flocs that have settled to the bottom are discharged, a large amount of wastewater will be discharged simultaneously, resulting in the need for secondary treatment, thereby increasing the difficulty of treating wastewater. The present technical solution can solve the above problem, and the specific operation is as follows:

[0067] First, the mixture of wastewater, decolorizing agent and flocculant is injected into the inner shell 3 through the water inlet pipe 2, and then stirred by the stirring mechanism. After the stirring is completed, the sealing block 6 pulls the pressing block 8 to move together through the first pushing mechanism, and the pressing block 8 is separated from the drain pipe 4, and the seal of the drain pipe 4 is cancelled, so that the wastewater in the inner shell 3 is discharged through the drain pipe 4. After passing through the drain pipe 4, the sewage reaches the filter block 10, and the flocculent sediment in the wastewater is filtered by the filter block 10, and the flocculent sediment is deposited in the drain pipe 4;

[0068] After the pressing block 8 is separated from the drain pipe 4 to cancel the seal of the drain pipe 4, the rotary drive mechanism is started, and the inner shell 3 is rotated by the rotary drive mechanism. Under the action of centrifugal force, the particles in the wastewater will move in the direction of the larger rotation radius and settle to the bottom, and finally enter the drain pipe 4, which is conducive to increasing the sedimentation speed of the particles in the wastewater. In addition, under the action of centrifugal force, the wastewater will pressurize the filter block 10, which is conducive to increasing the discharge speed of the wastewater;

[0069] After the wastewater is discharged, the sealing block 6 drives the pressing block 8 to move through the pushing mechanism, and the drain pipe 4 is sealed again. In the process of the sealing block 6 driving the pressing block 8 to move, a large amount of floccules in the drain pipe 4 occupies the space of the drain pipe 4, and the pressing block 8 is reversely squeezed, so that the first spring 7 is compressed and deformed. Since the force is mutual, the floccules in the drain pipe 4 are compressed in the process of the sealing block 6 pushing the pressing block 8 to continue to move, and then the wastewater in the floccules is squeezed, so that the wastewater in the floccules is fully squeezed out, and the squeezed wastewater enters the drain cavity 101 through the filter block 10 and the connecting pipe 9, and the wastewater in the drain cavity 101 is discharged through the external pipe;

[0070] After the extrusion is completed, the filter block 10 is moved into the connecting pipe 9 by the second pushing mechanism, so that a material discharge space is generated between the filter block 10 and the pressing block 8, and the waste residue between the filter block 10 and the pressing block 8 falls and is discharged under the action of gravity;

[0071] After the above operations are completed, the second pushing mechanism is used to move the filter block 10 closer to the end of the drain pipe 4 and contact the end of the drain pipe 4, and then the sealing block 6 is used to seal the drain pipe 4 again, and then the wastewater to be treated is injected through the water inlet pipe 2, and then the wastewater is treated again according to the above operations;

[0072] The wastewater treatment device is provided with a rotatable inner shell 3, a drain pipe 4, a sealing block 6, a pressing block 8 and a filter block 10. During the drainage process, the flocs in the wastewater are allowed to remain in the drain pipe 4, and then the pressing block 8 and the filter block 10 are squeezed against each other to complete the dehydration of the flocs, reduce the residual wastewater in the flocs, and do not require secondary treatment, thereby reducing the difficulty of treating dyeing wastewater.

[0078] Specifically, by providing the driving rod 15 and the cylinder 21, when it is necessary to discharge the waste water in the inner shell 3, the cylinder 21 is started, so that the cylinder 21 pulls the rotating seat 20 to move upward, thereby moving the driving rod 15 upward, and under the pulling of the connecting rod 19, the sealing block 6 pulls the pressing block 8 to move, and the pressing block 8 is separated from the drain pipe 4, thereby canceling the seal of the drain pipe 4, so that the waste water can be discharged through the drain pipe 4;

[0079] After the waste water is discharged, the telescopic rod of the cylinder 21 pushes the rotating seat 20 downward to move downward and reset, so that the driving rod 15 moves downward. Under the push of the connecting rod 19, the sealing block 6 is reinserted into the drain pipe 4 to seal the drain pipe 4. At the same time, the pressing block 8 squeezes the flocs in the drain pipe 4 to dehydrate the flocs.

[0088] Specifically, by providing the driving motor 22 and the upper sleeve 23, when the driving rod 15 moves upward, the first clamping block 16 enters the first clamping groove 2301 from the first annular groove 2302, and the second clamping block 17 enters the second annular groove 2401 from the second clamping groove 2402, and then the driving motor 22 is used to rotate the driving rod 15, and under the effect of the clamping, the inner shell 3 is rotated synchronously;

[0089] During the downward movement of the driving rod 15, the first clamping block 16 enters the first annular groove 2302 from the first clamping groove 2301, and the second clamping block 17 enters the second annular groove 2401 into the second clamping groove 2402. Subsequently, the driving motor 22 is used to rotate the driving rod 15. Under the action of the clamping connection, the lower sleeve 24 drives the stirring rod 25 to rotate, thereby stirring the wastewater in the inner shell 3.

[0095] Specifically, by providing the U-shaped driving plate 26 and the pushing block 27, when the sealing block 6 drives the pressing block 8 to be inserted into the drain pipe 4, the pushing frame 28 first moves along the straight groove and then enters the inclined groove. Under the drive of the inclined groove, the U-shaped driving plate 26 is moved away from the pushing block 27. Under the action of the second spring 11, the filter block 10 is quickly moved away from the end of the drain pipe 4, thereby completing the slag discharge work;

[0096] In the process of the sealing block 6 driving the pressure block 8 away from the drain pipe 4, the pushing frame 28 first moves along the inclined groove and then enters the straight groove.

When the drain pipe 4 moves to the scraper 30, under the action of centrifugation, the flocs at the scraper 30 enter the drain pipe 4, and the flocs in the inner shell 3 are collected as much as possible, thereby reducing the residual flocs in the inner shell 3.

[0110] Working principle of the present invention:

[0111] First, the mixture of wastewater, decolorizing agent and flocculant is injected into the inner shell 3 through the water inlet pipe 2, and then stirred by the stirring mechanism. After the stirring is completed, the sealing block 6 pulls the pressing block 8 to move together through the first pushing mechanism, and the pressing block 8 is separated from the drain pipe 4, and the seal of the drain pipe 4 is cancelled, so that the wastewater in the inner shell 3 is discharged through the drain pipe 4. After passing through the drain pipe 4, the sewage reaches the filter block 10, and the flocculent sediment in the wastewater is filtered by the filter block 10, and the flocculent sediment is deposited in the drain pipe 4;

[0112] After the pressing block 8 is separated from the drain pipe 4 to cancel the seal of the drain pipe 4, the rotary drive mechanism is started, and the inner shell 3 is rotated by the rotary drive mechanism. Under the action of centrifugal force, the particles in the wastewater will move in the direction of the larger rotation radius and settle to the bottom, and finally enter the drain pipe 4, which is conducive to increasing the sedimentation speed of the particles in the wastewater. In addition, under the action of centrifugal force, the wastewater will pressurize the filter block 10, which is conducive to increasing the discharge speed of the wastewater;

[0113] After the wastewater is discharged, the sealing block 6 drives the pressing block 8 to move through the pushing mechanism, and the drain pipe 4 is sealed again. In the process of the sealing block 6 driving the pressing block 8 to move, a large amount of floccules in the drain pipe 4 occupies the space of the drain pipe 4, and the pressing block 8 is reversely squeezed, so that the first spring 7 is compressed and deformed. Since the force is mutual, the floccules in the drain pipe 4 are compressed in the process of the sealing block 6 pushing the pressing block 8 to continue to move, and then the wastewater in the floccules is squeezed, so that the wastewater in the floccules is fully squeezed out, and the squeezed wastewater enters the drain cavity 101 through the filter block 10 and the connecting pipe 9, and the wastewater in the drain cavity 101 is discharged through the external pipe;

[0114] After the extrusion is completed, the filter block 10 is moved into the connecting pipe 9 by the second pushing mechanism, so that a material discharge space is generated between the filter block 10 and the pressing block 8, and the waste residue between the filter block 10 and the pressing block 8 falls and is discharged under the action of gravity;

[0115] After completing the above operations, the second pushing mechanism is first used to move the filter block 10 back to the end of the drain pipe 4 and contact the end of the drain pipe 4, and then the sealing block 6 re-seals the drain pipe 4, and then the wastewater to be treated is injected through the water inlet pipe 2, and then the wastewater treatment is performed again according to the above operations.

[0116] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
