[0002] As a highly efficient separation equipment, hydrocyclone has been widely used in many industries. With its unique structural design and excellent separation performance, it has become an indispensable key device in many industrial processes. Due to its significant advantages such as simple operation, large processing capacity and high separation efficiency, hydrocyclone has demonstrated outstanding performance in these fields and is deeply favored by industry users.

[0003] In traditional hydrocyclones, the centrifugal force generated by the rotational motion of the fluid is used to effectively separate particles or liquids of different densities. However, when the hydrocyclone is in use, larger particles or fibrous materials can easily cause blockage of the internal channels of the cyclone. After long-term operation, impurities easily accumulate on the inner wall of the sand discharge pipe, causing blockage and reducing work efficiency. In order to better address the above-mentioned problems, promote the development of industry technology and enhance core competitiveness, this application proposes a new component structure that is different from the existing technology. Summary of the Invention

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0015] Reference Figure 1-Figure 3 A blockage-resistant hydrocyclone comprises a cylinder 1, a cone section 2 is welded to the bottom of the cylinder 1, a sand discharge pipe 3 is welded to the bottom of the cone section 2, an overflow pipe 9 is welded to the top of the cylinder 1, a water outlet pipe 8 is welded to one side of the overflow pipe 9, a connecting pipe 7 is welded to the outside of the cylinder 1, and the connecting pipe 7 is tangentially arranged on the outside of the cylinder 1, a fixing block is fixed to the outside of the sand discharge pipe 3 by bolts, and a first motor 4 is fixed to the bottom of the fixing block by bolts, one end of the output shaft of the first motor 4 passes through the fixing block box and the sand discharge pipe 3 is connected through a coupling. A rotating shaft 15 is connected, and a spiral scraper 14 is fixed to the outer side of the rotating shaft 15 by bolts, and the spiral scraper 4 is in contact with the inner wall of the sand discharge pipe 3. When in use, the first motor 4 is started to drive the rotating shaft 15 to rotate, and the spiral scraper 14 on the rotating shaft 15 rotates accordingly. The spiral scraper 14 contacts the inner wall of the sand discharge pipe 3, scrapes off the mud and sand attached to the inner wall of the sand discharge pipe 3, and discharges it smoothly to prevent the sand discharge pipe 3 from being blocked, thereby effectively preventing the sand discharge pipe 3 from being blocked, ensuring the smoothness of sand discharge, and improving the sand discharge efficiency of the hydrocyclone.

[0016] In the present invention, one end of the connecting pipe 7 is connected to the shell 6 through a flange, and a water inlet pipe 5 is welded to one side of the shell 6. A second motor 16 is fixed to one side of the shell 6 by bolts. One end of the output shaft of the second motor 16 passes through the shell 6 and is connected to the crushing roller 17 through a coupling. When in use, the second motor 16 is started to drive the crushing roller 17 to rotate, crushing larger impurities in the water into smaller particles. The crushed water flows tangentially into the cylinder 1 through the connecting pipe 7, avoiding blockage caused by large particles of impurities inside the equipment and improving the stability of the overall hydraulic transportation.

[0017] In particular, an umbrella-shaped filter cover 10 is fixed to the bottom of the overflow pipe 9 by bolts, and a gap is provided between the umbrella-shaped filter cover 10 and the cylinder 1. A plurality of guide holes 11 are provided on the outside of the umbrella-shaped filter cover 10, and the guide holes 11 are arranged radially, with the aperture increasing from the center to the outside. When the water flows through the filter cover through the umbrella-shaped filter cover 10, impurities of different particle sizes can be more reasonably separated under the centrifugal force and filtration action, thereby further improving the filtration effect. The inner wall of the cone section 2 is fixed with a spiral guide rib 1 by bolts. 2. The surface of the spiral guide rib 12 is provided with a wear-resistant coating, which can enable heavier solid particles such as mud and sand to move downward along the cone section 2. The spiral guide rib 12 on the inner wall of the cone section 2 can guide the mud and sand particles to move more smoothly toward the sand discharge pipe 3. The wear-resistant coating can effectively reduce the wear of the spiral guide rib 12 and extend its service life. A cone block 13 is fixed to the top of the rotating shaft 15 by bolts. The cone block 13 can change the flow direction of water at the top of the sand discharge pipe 3, so that the water flow is more concentrated and flows downward to the sand discharge pipe 3, thereby enhancing the sand discharge effect.

[0018] Working principle: During operation, water containing impurities such as silt flows into the housing 6 from the water inlet pipe 5, and the second motor 16 drives the crushing roller 17 to rotate, crushing the larger impurities in the water into smaller particles. The crushed water flows tangentially into the cylinder 1 through the connecting pipe 7. Due to the tangential arrangement of the connecting pipe 7, the water forms a rotating flow field in the cylinder 1. Under the action of centrifugal force, heavier solid particles such as silt are thrown to the inner wall of the cylinder 1 and move downward along the cone section 2. The spiral guide ribs 12 on the inner wall of the cone section 2 can guide the silt particles to move more smoothly to the sand discharge pipe 3. At the same time, the wear-resistant coating on its surface can effectively reduce the wear of the spiral guide ribs 12 and extend its service life. During the rotation of the water flow, the lighter clean water converges toward the center of the cylinder 1 and flows upward. After being filtered by the umbrella-shaped filter cover 10, it flows out through the overflow pipe 9 and is finally discharged from the outlet pipe 8. The guide holes 11 on the outside of the umbrella-shaped filter cover 10 are arranged radially, and the aperture increases from the center to the outside. This design enables impurities of different particle sizes to be more reasonably separated under the centrifugal force and filtration when the water flows through the filter cover, thereby further improving the filtration effect. When impurities such as silt enter the sand discharge pipe 3, the first motor 4 drives the rotating shaft 15 to rotate, and the spiral scraper 14 on the rotating shaft 15 rotates accordingly. The spiral scraper 14 contacts the inner wall of the sand discharge pipe 3, scrapes off the silt attached to the inner wall of the sand discharge pipe 3, and discharges it smoothly to prevent the sand discharge pipe 3 from being blocked. The cone block 13 on the top of the rotating shaft 15 can change the flow direction of water at the top of the sand discharge pipe 3, so that the water flow is more concentratedly flowed to the bottom of the sand discharge pipe 3, thereby enhancing the sand discharge effect. Through the coordinated work of various components, the anti-clogging hydrocyclone can efficiently realize water and sand separation, and effectively prevent the blockage of the sand discharge pipe, ensuring the stable operation of the equipment, thereby effectively preventing the blockage of the sand discharge pipe 3, ensuring the smoothness of sand discharge, and improving the sand discharge efficiency of the hydrocyclone. In addition, while embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
