Description

Technical Field

[0001] This utility model belongs to the technical field of hydrocyclone overflow pipe, specifically a hydrocyclone overflow pipe with an anti-adhesion inner wall. Background Technology

[0002] The overflow pipe of a hydrocyclone is a key component of a hydrocyclone system, primarily used to handle the flow of substances during liquid separation. A hydrocyclone itself is a device that uses centrifugal force generated by a high-speed rotating fluid to achieve solid-liquid separation or separation between liquids. When liquid enters the hydrocyclone, the centrifugal force generated by the liquid's rotation throws heavier solids against the hydrocyclone walls, forming an outward vortex. Lighter liquids or smaller substances experience less centrifugal force and are forced to flow towards the center of the hydrocyclone, eventually being discharged through the overflow pipe.

[0003] The high-speed rotation of the fluid inside a hydrocyclone generates strong centrifugal force, causing heavier particles to move outwards towards the pipe wall and be separated. The overflow pipe of the hydrocyclone is usually located at the top of the equipment and discharges the liquid or lighter particles that were not separated inside the hydrocyclone. However, because the flow velocity in the overflow pipe and at the pipe inlet is relatively slow, the change in fluid velocity can easily cause some smaller particles and impurities to lack sufficient kinetic energy to be completely discharged with the liquid flow, thus depositing on the pipe wall and gradually adhering and accumulating. Summary of the Invention

[0004] The purpose of this invention is to provide a hydrocyclone overflow pipe with an anti-adhesion inner wall to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an overflow pipe for a hydrocyclone with anti-adhesion inner wall, comprising a hydrocyclone body and a feed pipe. The feed pipe is connected to the outer side of the hydrocyclone body, the lower end of the hydrocyclone body is connected to a sand settling nozzle, the inner side of the hydrocyclone body is connected to an overflow pipe body, and two supports are sequentially fixed to the inner side of the overflow pipe body. The upper side of the supports is movably connected to a bevel gear through a bearing, and the lower side of the bevel gear is fixed to a support plate through a central rod. The two support plates are movably connected to a scraper through a bearing.

[0006] Preferably, the first bevel gear and the second bevel gear are engaged with each other, and the second bevel gear is movably connected to the bracket via a bearing.

[0007] Preferably, the side of the support plate away from the scraper is movably connected to the toothed disc via a bearing, and the toothed disc is fixed to the scraper via a central rod.

[0008] Preferably, the toothed disc is in contact with the toothed ring, and one side of the toothed ring is fixed to one end of the support rod.

[0009] Preferably, the end of the support rod away from the toothed ring is fixed to the overflow pipe body.

[0010] Preferably, the support plate on the lower side of the overflow pipe body is connected to the connecting rod, and a spiral stirring rod is fixed at the end of the connecting rod near the sand settling nozzle.

[0012] Preferably, the scraper is pressed against the hydrocyclone body, and the toothed disc and toothed ring are engaged.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When using this invention, the drive motor is started, causing the support plate to move the scraper along the inner side of the overflow pipe body. This allows the scraper to scrape off particles and debris adhering to the inner wall of the overflow pipe body. The scraper can also rotate while moving, thereby improving the cleaning effect on the inner side of the overflow pipe body. At the same time, the spiral stirring rod rotates, which can push the solid particles deposited inside the sand settling nozzle towards the bottom outlet of the hydrocyclone body, preventing excessive accumulation of sediment. This allows the hydrocyclone to clean the inner wall of the overflow pipe body while preventing heavier solid particles from clogging the hydrocyclone body. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: an overflow pipe for a hydrocyclone with an anti-adhesion inner wall, comprising a hydrocyclone body 1 and a feed pipe 101. The feed pipe 101 is connected to the outer side of the hydrocyclone body 1, and the lower end of the hydrocyclone body 1 is connected to a sand settling nozzle 102. The inner side of the hydrocyclone body 1 is connected to an overflow pipe body 103. Two supports 2 are sequentially fixed to the inner side of the overflow pipe body 103. The upper side of the supports 2 is movably connected to a bevel gear 201 via a bearing, and the lower side of the bevel gear 201 is fixed to a support plate 203 via a central rod. The two support plates 203 are movably connected to a scraper 204 via a bearing. The bevel gear 201 and the bevel gear 202 are aligned, and the bevel gear 202 is movably connected to the supports 2 via a bearing. The side of plate 203 away from scraper 204 is movably connected to toothed disc 205 via bearing, and toothed disc 205 is fixed to scraper 204 via central rod. Toothed disc 205 is in contact with toothed ring 206, and one side of toothed ring 206 is fixed to one end of support rod 207. The end of support rod 207 away from toothed ring 206 is fixed to overflow pipe body 103. Support plate 203 on the lower side of overflow pipe body 103 is connected to connecting rod 208, and spiral stirring rod 209 is fixed to the end of connecting rod 208 near sand outlet 102. Bevel gear 1 201 and bevel gear 202 are meshed. Scraper 204 is made of deformable silicone material. Scraper 204 is pressed against hydrocyclone body 1. Toothed disc 205 and toothed ring 206 are meshed.

[0022] In specific implementation, according to Figures 1-4Liquid enters the hydrocyclone body 1 through the feed pipe 101. At this time, the fluid inside the feed pipe 101 rotates at high speed, causing heavier particles to move outwards towards the settling nozzle 102, while lighter liquids or finer substances are forced towards the center of the hydrocyclone body 1 by a smaller centrifugal force, and finally discharged through the overflow pipe body 103. At this point, the drive motor 2021 is started, causing its output to drive the second bevel gear 202 to rotate. This rotation occurs through the interaction between the first bevel gear 201 and the second bevel gear... The two bevel gears 202 are meshed together, allowing the first bevel gear 201 to rotate along with the second bevel gear 202. The first bevel gear 201 drives the two support plates 203 to rotate via the central rod. This causes the support plates 203 to move the scraper 204 along the inner side of the overflow pipe body 103. The scraper 204, made of deformable silicone material, presses against the hydrocyclone body 1, allowing it to scrape off particles and debris adhering to the inner wall of the overflow pipe body 103. Meanwhile, the support plates 203... When the scraper 204 moves along the inner side of the overflow pipe body 103, the support plate 203 also drives the toothed disc 205 to rotate. The toothed disc 205 meshes with the toothed ring 206, causing the toothed disc 205 to rotate simultaneously with the scraper 204 moving along the inner side of the overflow pipe body 103. This allows the toothed disc 205 to drive the scraper 204 to rotate itself, improving the cleaning effect of the scraper 204 on the inner side of the overflow pipe body 103. Meanwhile, the support plate... 203 drives the connecting rod 208 to rotate, which in turn drives the spiral stirring rod 209 to rotate. This allows the spiral stirring rod 209 to agitate the heavier solid particles inside the settling nozzle 102. The mechanical force generated by the spiral stirring rod 209 can push the solid particles deposited inside the settling nozzle 102 toward the bottom outlet of the hydrocyclone body 1, preventing excessive accumulation of sediment. This allows the hydrocyclone to clean the inner wall of the overflow pipe body 103 while preventing heavier solid particles from clogging the hydrocyclone body 1.

[0023] In summary, when using this utility model, starting the drive motor 2021 causes the support plate 203 to move the scraper 204 along the inner side of the overflow pipe body 103. This allows the scraper 204 to scrape off particles and debris adhering to the inner wall of the overflow pipe body 103. Simultaneously, as the support plate 203 moves the scraper 204 along the inner side of the overflow pipe body 103, the support plate 203 also drives the toothed disc 205 to rotate, enabling the scraper 204 to rotate while moving. This improves the cleaning effect of the scraper 204 on the inner side of the overflow pipe body 103. At the same time, the spiral stirring rod 209 rotates, generating mechanical force that pushes the solid particles deposited inside the sedimentation nozzle 102 towards the bottom outlet of the hydrocyclone body 1, preventing excessive accumulation of sediment. This ensures that the hydrocyclone cleans the inner wall of the overflow pipe body 103 while preventing heavier solid particles from clogging the hydrocyclone body 1.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
