As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 8, the present invention provides a hydrocyclone with self-cleaning function, which includes a supporting frame 10, a cyclone cone 20 penetrating the supporting frame 10, and a self-cleaning assembly 30 sleeved outside the cyclone cone 20 for cleaning an inner wall of the cyclone cone 20. A plurality of rows of first cleaning holes 21 are formed in the bottom end shell of the rotational flow conical cylinder 20, wherein the axes of the corresponding two rows of first cleaning holes 21 are staggered up and down.
For the self-cleaning assembly 30, the self-cleaning assembly 30 includes a water jacket 32 sleeved outside the spiral-flow cone 20 and fixed inside the support frame 10, and a sealing sleeve 31 located in a gap between the water jacket 32 and the spiral-flow cone 20 and rotatably connected to the support frame 10.
In the present embodiment, an annular water storage bag 34 and a waste water treatment assembly 33 are sequentially disposed from top to bottom in the gap formed between the sealing sleeve 31 and the water storage jacket 32. Wherein the annular water storage bag 34 is connected with a pressurized water pump through a pipeline. The casing of the sealing sleeve 31 is provided with second cleaning holes 36 corresponding to the first cleaning holes 21 one by one. In practical applications, when the annular water storage bag 34 is filled with water and expands, the cleaning nozzle 35 sequentially passes through the second cleaning hole 36 and the first cleaning hole 21 to clean the inner wall of the cyclone cone 20.
In the embodiment, when the inner wall surface of the swirling cone 20 is adhered with excessive impurities, the pump body injects water into the swirling cone 20 and the annular water storage bag 34 sleeved outside the swirling cone 20, so that the annular water storage bag 34 expands until the cleaning nozzles 35 on the annular water storage bag 34 enter the water storage jacket 32 through the first cleaning hole 21 on the swirling cone 20 and the second cleaning hole 36 on the sealing sleeve 31; the valve body on the cleaning nozzle 35 is opened, so that the cleaning nozzle 35 sprays high-pressure water flow, and the inner wall hardened impurities of the rotational flow conical cylinder 20 are cleaned by the high-pressure water flow.
In practical application, the sealing sleeve 31 sleeved outside the swirling cone 20 rotates, so that the second cleaning hole 36 on the sealing sleeve 31 and the first cleaning hole 21 on the swirling cone 20 are dislocated, the swirling effect inside the swirling cone 20 is not affected, and fluid in the swirling cone 20 is prevented from entering the water storage jacket 32 carrying the annular water storage bag 34.

Additionally, a rubber pad 313 is bonded to the inner wall surface of the sealing sleeve 31.
It should be noted that, since the second support table 12 is located on a support surface such as the ground, the top end of the second support table 12 is connected to the first support table 11 through the support column 13, and the swirling flow cone 20 is inserted into the first support table 11, the first support table 11 can be used to provide stable support for the swirling flow cone 20.
It should be noted that, since the volume of the second support table 12 is larger than that of the first support table 11, the arrangement may enable the support frame 100 composed of the first support table 11 and the second support table 12 to form a large-small head structure, thereby improving the stability of the support frame 100. On the other hand, the rubber pad 313 on the inner wall of the sealing sleeve 31 reduces the gap between the sealing sleeve and the cyclone cone 20, thereby improving the sealing performance of the cyclone cone 20.
In the present invention, the seal sleeve 31 is fixed to the outer peripheral surface of the top end of the first support table 11, and a support ring 311 is fixed to the outer peripheral surface of the bottom end of the support ring 311, and a plurality of balls 312 are embedded in the bottom end surface of the support ring 311. The balls 312 are slidably connected to the annular sliding groove 111, the annular sliding groove 111 is opened inside the first support table 11, and the driving end of the sealing sleeve 31 is connected to the power assembly 37.
The power assembly 37 includes a motor 371 fixed inside the first support stage 11, a speed reducer 374 connected to an output shaft of the motor 371, a bevel gear 372 fixed to an output shaft of the speed reducer 374, and a bevel gear ring 373 engaged with a bottom end of the bevel gear 372 and fixed to a top end surface of the support ring 311.
It should be noted that, because the top end of the sealing sleeve 31 is supported on the first supporting table 11 through the upper supporting ring 311, and because the bottom end surface of the supporting ring 311 is embedded with the balls 312, this arrangement can make the supporting ring 311 roll inside the first supporting table 11 through the balls 312 at the bottom end thereof when rotating, thereby preventing dry friction between the supporting ring 311 and the first supporting table 11, and prolonging the service life of the supporting ring 311 and the first supporting table 11.
Furthermore, the above-mentioned structure can make the output shaft of the motor 371 drive the speed reducer 374 connected with it to rotate, because the bevel gear 372 on the output shaft of the speed reducer 374 is meshed with the bevel gear ring 373 at the top end of the support ring 311, so as to transmit the torque to the bevel gear ring 373 at the top end of the support ring 311 and drive the sealing sleeve 31 on the bevel gear ring 373 to rotate, and through the arrangement of the speed reducer 374, the torque when the sealing sleeve 31 rotates is improved.

Furthermore, after the high-temperature gas in the aeration chamber 3321 enters the water storage jacket 32, a large amount of sewage entering the aeration chamber 3321 from the cyclone cone 20 is retained at the top ends of the water storage jacket 32 and the aeration chamber 3321, so that the sewage is aerated and sterilized by the aeration head 3322 on the aeration chamber 3321, and the fine filtering sand layer 3311 in the filtering mechanism 331 is washed away, thereby prolonging the service life of the fine filtering sand layer 3311.
Further, after sewage flows through the first cleaning hole 21 on the rotational flow cone cylinder 20 and the second cleaning hole 36 on the sealing sleeve 31 and enters the water storage jacket 32; since the coarse filtering sand layer 3312 and the fine filtering sand layer 3311 are sequentially disposed in the gap between the aeration chamber 3321 and the annular water storage bag 34 inside the water storage jacket 32 from top to bottom, the coarse filtering sand layer 3312 and the fine filtering sand layer 3311 are used to filter the sewage, thereby reducing secondary pollution inside the cyclone.
Further, the slope of the top end of the aeration chamber 3321 is used to guide the filtered sand of the coarse filtering sand layer 3312 and the fine filtering sand layer 3311 to be discharged, thereby accelerating the worker to replace the coarse filtering sand layer 3312 and the fine filtering sand layer 3311.
The water storage jacket 32 can guide the filtering sand of the coarse filtering sand layer 3312 and the fine filtering sand layer 3311 to be discharged through the plurality of sand discharge valves 321 arranged at the bottom end, so that the worker can replace the coarse filtering sand layer 3312 and the fine filtering sand layer 3311 more quickly.
