Description

Technical Field

[0001] This utility model relates to the field of cyclone separation technology, specifically to a mud and sand cyclone separation device that facilitates material discharge. Background Technology

[0002] Hydrocyclones are common separation and classification devices, often based on the principle of centrifugal sedimentation. When two mixtures to be separated enter the hydrocyclone tangentially from its periphery under a certain pressure, they generate intense three-dimensional elliptical strong rotational shear turbulence. Due to the size difference between coarse and fine particles, they experience different magnitudes of centrifugal force, centripetal buoyancy, and fluid drag. Under centrifugal sedimentation, most coarse particles are discharged through the underflow outlet of the hydrocyclone, while most fine particles are discharged through the overflow pipe, thus achieving separation and classification. However, in the long-term use of traditional hydrocyclones, sometimes used for separating water and sediment, the sediment mixed with water has strong adhesion. When a large amount of sediment is discharged from the discharge port, it may cause blockage of the hydrocyclone outlet, requiring manual cleaning and affecting construction efficiency. Furthermore, during material feeding, existing hydrocyclones can cause sediment to accumulate in a cone shape, requiring continuous handling by workers. Failure to handle this promptly can also cause blockage of the discharge port.

[0003] The existing announcement number CN215030135U discloses a hydrocyclone with anti-clogging function. This hydrocyclone uses a motor and support rod installed outside the housing. The motor drives a rotating shaft to rotate, causing a first slider to move in a first groove. A moving rod drives a connecting rod to rotate, which in turn drives a second slider to move. When the connecting rod performs circular motion, a second limiting rod converts the circular motion into linear motion. After one end of the second slider touches the outer wall of the housing, it strikes the housing, knocking off the mud and sand that are about to clog the bottom of the inner wall, thus preventing blockage at the outlet. When using the above-mentioned hydrocyclone… The anti-clogging mechanism relies on the impact of the second slider on the hydrocyclone outlet to generate vibration. Although the moving rod can provide cushioning, the hydrocyclone still needs to vibrate to achieve the anti-clogging purpose. However, during operation, prolonged vibration can loosen the connection at the hydrocyclone inlet, thereby reducing the transmission pressure. This prevents the separation of mud and water entering the hydrocyclone. Furthermore, during the separation of mud and sand, the raw material also contains other impurities, such as activated sludge flocs. When these flocs clog the outlet, vibration alone cannot effectively clear the blockage.

[0004] Based on this, we now offer a sludge hydrocyclone separator that facilitates material discharge and eliminates the drawbacks of existing equipment. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-6 As shown, a silt hydrocyclone separator for easy discharge includes a hydrocyclone body 11. One end of the hydrocyclone body 11 is connected to a feed pipe 12, and the bottom end is connected to a discharge pipe 13. Several support legs 14 are fixedly mounted on the hydrocyclone body 11. A connecting rod 15 is fixedly mounted on one side of each support leg 14, with one end of the connecting rod 15 fixedly connected to the hydrocyclone body 11. A receiving box 19 is located below the discharge pipe 13, and a fixing frame 20 is fixedly mounted at the bottom of the receiving box 19, positioned between two support legs 14. A rotating mounting hole is located within the discharge pipe 13. The first mounting shaft 16 has one end rotatably mounted in the mounting hole inside the discharge pipe 13, and the other end rotatably mounted inside the mounting tube inside a support leg 14. Several crushing rods 17 are fixedly mounted at one end of the first mounting shaft 16 corresponding to the position inside the discharge pipe 13. A driving component for driving the first mounting shaft 16 to rotate is provided on a connecting rod 15. The receiving box 19 is provided with a pushing mechanism for pushing out mud and sand. The pushing mechanism facilitates the pushing out of the mud and sand inside the receiving box 19, thereby preventing the accumulation of mud and sand inside the receiving box 19 from clogging the discharge pipe 13.

[0028] The drive assembly includes a motor 18, which is fixedly mounted on one side of a first fixed plate. The first fixed plate is fixedly mounted on a connecting rod 15. An active friction wheel is fixedly mounted on the output end of the motor 18, and a driven friction wheel is rubbed on the active friction wheel. The driven friction wheel is fixedly mounted on one end of a first mounting shaft 16. In use, when the hydrocyclone body 11 separates mud and sand, the motor 18 is started. The output end of the motor 18 drives the active friction wheel to rotate. The active friction wheel drives the first mounting shaft 16 to rotate through the driven friction wheel. The first mounting shaft 16 passes through several crushing rods 17, which facilitates the crushing of mud and sand blocked at the bottom of the hydrocyclone body 11 and inside the discharge pipe 13, thereby facilitating the discharge of mud and sand.

[0029] The feeding mechanism includes a scraper 22, which is slidably disposed inside the receiving box 19. The upper end of the scraper 22 is symmetrically provided with fixed mounting plates. Each of the two fixed mounting plates has a rectangular through hole and a threaded hole on one side. A guide rod is slidably disposed within the rectangular through hole. Second fixed plates are fixedly disposed at both ends of the guide rod. The second fixed plates are fixedly disposed at the upper end of the receiving box 19. A reciprocating lead screw 23 is disposed within the threaded hole. A third fixed plate is rotatably disposed at both ends of the reciprocating lead screw 23. The plate is fixedly mounted on the upper end of the receiving box 19. One end of the reciprocating screw 23 is fixedly provided with a first driven wheel. The first driven wheel is connected to the first driving wheel on one end of the first mounting shaft 16 via a first belt. In use, when the first mounting shaft 16 rotates, the first mounting shaft 16 drives the reciprocating screw 23 to rotate via the first belt. The reciprocating screw 23 drives the scraper plate 22 to slide inside the receiving box 19, thereby pushing the mud and sand inside the receiving box 19 to both ends of the receiving box 19, so that the mud and sand are discharged from the inside of the receiving box 19.

[0030] Both ends of the receiving box 19 are fixed with guide plates 24, which are inclined to facilitate the falling of mud and sand during use.

[0031] The bottom of the receiving box 19 is provided with an installation hole, and a filter plate 21 is fixedly installed in the installation hole. In use, it is convenient to drain the water inside the receiving box 19 through the filter plate 21, thereby reducing the resistance encountered by the scraper plate 22 when it moves.

[0032] Below the filter screen 21, there is an installation plate 25. Several unclogging nails are fixed to the upper end of the installation plate 25. The installation plate 25 is fixed to the bottom inner side of the sliding frame 26. The sliding frame 26 is slidably disposed within the sliding hole at the upper end of the fixed frame 20. Guide plates 27 are fixed to one end of the inner side of each sliding frame 26. Top rods 28 are tightly attached to the bottom end of each guide plate 27. The top rods 28 are fixed to the upper ends of the mounting brackets on both sides of the receiving box 19. Connecting plates are fixed to both sides of the sliding frame 26. Damping springs 29 are fixed to the upper end of each connecting plate. The other end of the damping springs 29 is connected to the upper end of the fixed frame 20. The end support frame is fixedly connected to the inside. When the receiving box 19 moves, the receiving box 19 drives the top rod 28 to move. When one end of the top rod 28 is in close contact with the bottom end of the guide plate 27, the guide plate 27 guides the sliding frame 26, so that the sliding frame 26 slides in the sliding hole at the upper end of the fixed frame 20. When the receiving box 19 moves beyond the upper end of the filter screen plate 21, the unblocking nail at the upper end of the mounting plate 25 is inserted into the filter hole at the upper end of the filter screen plate 21, thereby cleaning the filter hole at the upper end of the filter screen plate 21. When one end of the top rod 28 is disengaged from the bottom end of the guide plate 27, the sliding frame 26 returns to the initial position under the action of the damping spring 29.

[0033] Each of the top rods 28 is equipped with a ball bearing at one end, which helps to reduce wear between one end of the top rod 28 and the bottom end of the guide plate 27 during use.

[0034] The mounting plate 25 has several rectangular perforations at its upper end, which facilitates the rapid discharge of sewage from the upper end of the mounting plate 25 during use.

[0035] A connecting pipe is connected to the feed pipe 12. A second mounting shaft 30 is rotatably mounted inside the connecting pipe. Several crushing blades 31 are fixedly mounted at one end of the second mounting shaft 30 at a position corresponding to the inside of the feed pipe 12. A sealing ring 33 is provided on the second mounting shaft 30 at a position corresponding to one end of the connecting pipe. Several rotating blocks are rotatably mounted on the second mounting shaft 30. Each rotating block is fixed to one side of a support leg 14. A first conical friction wheel is fixedly mounted at one end of the second mounting shaft 30. A second conical friction wheel is rubbed on the first conical friction wheel. The second conical friction wheel is fixedly mounted at one end of the drive shaft 32. A second driven wheel on the drive shaft 32 is connected to an electric motor via a second belt. The second drive wheel is connected to the output end of the motor 18. Several rotating plates are rotatably mounted on the drive shaft 32. The rotating plates are fixed on a connecting rod 15. In use, when the motor 18 rotates, the output end of the motor 18 drives the drive shaft 32 to rotate through the second belt. The drive shaft 32 drives the second mounting shaft 30 to rotate through the cooperation of the first conical friction wheel and the second conical friction wheel. The second mounting shaft 30 drives several crushing blades 31 to rotate, thereby crushing impurities such as activated sludge flocs in the raw liquid entering the hydrocyclone body 11. The second mounting shaft 30 can be replaced according to actual use. The attached figure is only a schematic diagram to prevent impurities from clogging the discharge pipe 13.

[0036] The above embodiments disclose a sludge hydrocyclone separator that facilitates material discharge. When sludge separation is required, one end of the feed pipe 12 is connected to the output end of the liquid supply component. Then, the liquid supply component and the motor 18 are started. The output end of the motor 18 drives the drive shaft 32 to rotate via a second belt. The drive shaft 32 drives the second mounting shaft 30 to rotate via a first conical friction wheel and a second conical friction wheel. The second mounting shaft 30 drives several crushing blades 31 to rotate. The liquid supply component delivers the raw liquid through the feed pipe 12. Inside the hydrocyclone body 11, the crushing blades 31 crush impurities such as activated sludge flocs in the raw liquid entering the hydrocyclone body 11. The hydrocyclone body 11 then separates the sludge and liquid. The sludge is discharged through the discharge pipe 13 at the bottom of the hydrocyclone body 11. Simultaneously, the output of the motor 18 drives the active friction wheel to rotate. The active friction wheel, through the driven friction wheel, drives the first mounting shaft 16 to rotate. The first mounting shaft 16, via several crushing rods 17, facilitates the crushing of the bottom of the hydrocyclone body 11 and the discharge pipe 13. The internal blockage of mud and sand is broken up to facilitate its discharge. The mud and sand fall to the bottom of the receiving box 19, where the filter screen 21 facilitates the discharge of liquid from the receiving box 19. Simultaneously, when the first mounting shaft 16 rotates, it drives the reciprocating screw 23 via the first belt. The reciprocating screw 23 drives the scraper 22 to slide inside the receiving box 19, pushing the mud and sand inside the receiving box 19 towards both ends, allowing the mud and sand to be discharged from the receiving box 19. When the receiving box 19 moves, it is accompanied by… When the moving push rod 28 moves and one end of the push rod 28 is in close contact with the bottom end of the guide plate 27, the guide plate 27 guides the sliding frame 26, so that the sliding frame 26 slides in the sliding hole at the upper end of the fixed frame 20. When the receiving box 19 moves beyond the upper end of the filter screen plate 21, the unblocking nail at the upper end of the mounting plate 25 is inserted into the filter hole at the upper end of the filter screen plate 21, thereby cleaning the filter hole at the upper end of the filter screen plate 21. When one end of the push rod 28 is disengaged from the bottom end of the guide plate 27, the sliding frame 26 returns to the initial position under the action of the damping spring 29.

[0037] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
