Description

Technical Field

[0001] The utility model relates to the technical field of hydrocyclones, and more particularly to a hydrocyclone that is convenient for feeding. Background Art

[0002] A hydrocyclone is a device that uses centrifugal force to perform separation operations. It has certain applications in sewage pretreatment, industrial wastewater treatment, mining wastewater treatment, and other fields. In sewage pretreatment, it can quickly remove larger suspended particles in sewage, reducing the burden on subsequent treatment processes.

[0003] The existing water cyclone is not convenient for adjusting the opening of the water cyclone, so the height of the water cyclone cannot be adjusted, which makes it difficult to adapt to the height of the installation site, thereby wasting space.

[0004] After searching, the Chinese patent with authorization announcement number CN218554419U discloses a hydrocyclone. This structure adjusts the height of the device by adjusting the opening formed by two discharge blades to adapt to the height of the installation site, effectively saving space and reducing staff adjustment time. At the same time, it avoids the situation where inconsistent discharge blade angles have an adverse effect on water flow rotation, resulting in a decrease in the classification efficiency of the hydrocyclone. Moreover, when the raw material enters the hydrocyclone through the feed pipe, excessive sediment agglomerates will be filtered by the filter cartridge, thereby improving the classification efficiency. The internal dimensions of the filter cartridge are the same as those of the cylindrical barrel, which can ensure the cylindricity of the hydrocyclone.

[0005] However, in actual use, the overflow port of this structure is located at the top center of the cylindrical section of the cyclone, and its position is fixed. The depth of the overflow pipe inserted into the cyclone cannot be changed, and thus the overflow flow rate and particle size cannot be controlled according to actual conditions. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a hydrocyclone that is easy to feed, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A hydrocyclone for convenient feeding, comprising a vortex body, a feeding pipe penetrating one side of the vortex body, a fixing pipe penetrating the top of the vortex body, and an adjusting mechanism disposed inside the fixing pipe;

[0009] The adjusting mechanism includes a fixing groove provided on the surface of the fixing pipe, a U-shaped block is clamped inside the fixing groove, an overflow pipe is provided on one side of the fixing pipe, a plurality of clamping grooves are provided on the surface of the overflow pipe, the U-shaped block is plugged into the clamping grooves, a connecting ring is fixedly provided on the outside of the fixing pipe, a first fixing ring is fixedly provided on the bottom of the vortex body, the bottom of the first fixing ring is connected to a straight cylinder by bolts, an anti-blocking grille is fixedly provided on the bottom of the overflow pipe, and the surface of the anti-blocking grille is set to be conical.

[0010] By adopting the above technical solution: in order to facilitate the adjustment of the overflow pipe, the depth of the overflow pipe inserted into the straight cylinder can be changed, thereby facilitating the control of the overflow flow rate and particle size.

[0011] As a further description of the above technical solution: a feeding mechanism is provided on one side of the feeding pipe, and the feeding mechanism includes a fixed frame fixedly arranged on one side of the feeding pipe, and a connecting plate is connected to one side of the fixing frame by bolts, and a through hole is opened on the surface of the connecting plate, and a feeding pipe is provided through one side of the connecting plate, and a branch feeding pipe is provided through one side of the feeding pipe, and the surfaces of the feeding pipe and the branch feeding pipe are both configured as cones.

[0012] By adopting the above technical solution: in order to form a smooth flow field in the vortex body when the sewage is fed, the solid particles and the liquid are separated in an orderly manner under the action of centrifugal force, thereby improving the separation accuracy of the solid particles and the liquid in the sewage.

[0013] As a further description of the above technical solution: an upper vertebra is provided through the bottom of the straight cylindrical body, a middle vertebra is provided through the bottom of the upper vertebra, a lower vertebra is provided through the bottom of the middle vertebra, a sand settling spout is provided through the bottom of the lower vertebra, a threaded groove is provided on the surface of the sand settling spout, and a splash guard is connected to the internal thread of the threaded groove.

[0014] By adopting the above technical solution: in order to strengthen the centrifugal force, it is also possible to effectively prevent the solid impurities at the bottom from injuring people when being discharged.

[0015] The technical effects and advantages of this utility model are:

[0016] 1. By setting up an adjustment mechanism, compared with the existing technology, the U-shaped block is pulled outward, thereby driving the U-shaped block to separate from the fixed groove and the clamping slot, thereby moving the overflow pipe up and down to adjust the overflow pipe, and then the overflow pipe moves inside the fixed pipe. After determining the position, the U-shaped block is inserted into the clamping slot at the appropriate position and then fixed in the fixed groove to complete the adjustment. The position of the overflow pipe can be flexibly adjusted to control the overflow flow rate and particle size. In addition, the splash guard at the bottom of the sand settling mouth effectively prevents fixed impurities from splashing, and the splash guard is easy to replace.

[0017] 2. By setting up a feeding mechanism, compared with the existing technology, the sewage enters the interior of the feed pipe through the feed pipe and the branch feed pipe, and is then transported to the interior of the vortex body through the feed pipe. The feed pipe and the branch feed pipe can gradually reduce the flow velocity of the sewage when it enters the vortex body, reducing the impact on the flow field inside the vortex body, and at the same time allowing the fluid to enter the vortex body more smoothly. The feeding direction of the branch feed pipe is consistent with the tangential rotation direction inside the vortex body, so that the material can enter the vortex body more evenly, avoiding flow field turbulence caused by excessive feed flow from a single inlet.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The embodiments of this application disclose Figure 1-5 The hydrocyclone shown here is convenient for feeding, and comprises a vortex body 1, a feeding pipe 2 is provided through one side of the vortex body 1, a fixing pipe 3 is provided through the top of the vortex body 1, and an adjusting mechanism is provided inside the fixing pipe 3;

[0026] The regulating mechanism includes a fixing groove 4 provided on the surface of the fixing pipe 3, a U-shaped block 5 is clamped inside the fixing groove 4, an overflow pipe 6 is provided on one side of the fixing pipe 3, a plurality of clamping grooves 7 are provided on the surface of the overflow pipe 6, the U-shaped block 5 is plugged into the clamping groove 7, a connecting ring 8 is fixedly provided on the outside of the fixing pipe 3, a first fixing ring 9 is fixedly provided on the bottom of the vortex body 1, and a straight cylinder 10 is connected to the bottom of the first fixing ring 9 by bolts, an anti-blocking grille 22 is fixedly provided on the bottom of the overflow pipe 6, and the surface of the anti-blocking grille 22 is set to be conical. Due to the different densities of solid particles and liquids, the centrifugal forces they are subjected to are also different. After the sewage enters the vortex body 1, a rotating flow field is quickly formed, and the tangential velocity gradually decreases from the wall surface of the vortex body 1 to the center. In the area close to the wall surface, the tangential velocity is large, and then passes through the upper vertebral body 16, the middle vertebral body 17 and the lower vertebral body 18, and at the high In the rapidly rotating flow field, the diameter gradually decreases and the rotation radius decreases, thereby increasing the centrifugal force, which is conducive to further separating the solid particles from the liquid. The solid particles with larger density are thrown to the wall of the device under the greater centrifugal force, and move downward in a spiral along the inner wall of the upper vertebral body 16, the middle vertebral body 17 and the lower vertebral body 18, and are finally discharged from the sand settling spout 19. When it is necessary to adjust the depth of the overflow pipe 6 inside the straight cylindrical body 10, the U-shaped block 5 is first pulled outward, thereby driving the U-shaped block 5 to separate from the fixed groove 4 and the card slot 7, thereby moving the overflow pipe 6 up and down to adjust it, and then the overflow pipe 6 moves inside the fixed pipe 3. After determining the position, the U-shaped block 5 is inserted into the card slot 7 at the appropriate position, and enters the fixed groove 4 for fixation, and then the adjustment is completed. The position of the overflow pipe 6 is flexibly adjusted to control the overflow flow rate and particle size.

[0027] Reference Figure 2-3 As shown, a feeding mechanism is provided on one side of the feed pipe 2, and the feeding mechanism includes a fixing frame 11 fixedly provided on one side of the feed pipe 2, and a connecting plate 12 is connected to one side of the fixing frame 11 by bolts. A through hole 13 is provided on the surface of the connecting plate 12, and a feed pipe 14 is provided through one side of the connecting plate 12, and a branch feed pipe 15 is provided through one side of the feed pipe 14. The surfaces of the feed pipe 14 and the branch feed pipe 15 are both set to be cones, and the sewage enters the feed pipe 14 and the branch feed pipe 15 through the feed pipe 14 and the branch feed pipe 15. The sewage enters the vortex body 1 through the feed pipe 2 and is then transported to the inside of the vortex body 1 through the feed pipe 2. The feed pipe 14 and the branch feed pipe 15 can gradually reduce the flow rate of the sewage when it enters the vortex body 1, reducing the impact on the internal flow field of the vortex body 1, and at the same time can make the fluid enter the vortex body 1 more smoothly. The feeding direction of the branch feed pipe 15 is consistent with the tangential rotation direction in the vortex body 1, so that the material can enter the vortex body 1 more evenly, avoiding the flow field turbulence caused by excessive feed flow from a single inlet.

[0028] Reference Figure 3-5As shown, the bottom of the straight cylindrical body 10 is provided with an upper vertebral body 16, the bottom of the upper vertebral body 16 is provided with a middle vertebral body 17, the bottom of the middle vertebral body 17 is provided with a lower vertebral body 18, and the bottom of the lower vertebral body 18 is provided with a sand settling mouth 19. The surface of the sand settling mouth 19 is provided with a thread groove 20. The internal thread of the thread groove 20 is connected with a splash shield 21. The splash shield 21 effectively prevents fixed impurities from splashing, and the splash shield 21 is always rubbed with the fixed impurities and is easily worn. The rotation of the splash shield 21 drives the splash shield 21 and the thread groove to rotate. 20 is separated, so that the splash shield 21 is removed and replaced, which is easy and quick to operate, and the liquid with lower density forms an inward vortex and moves toward the center, passes through the anti-blocking grille 22 and then enters the overflow pipe 6 and flows out. The mesh size of the grille is determined according to the size of the particles to be separated, which can prevent large particles from entering the overflow pipe 6 and causing blockage, and ensure that the fluid can flow out smoothly. At the same time, the surface of the anti-blocking grille 22 is set to be conical, so that impurities filtered under the surface can be discharged smoothly by gravity, and avoid entering the overflow pipe 6 and forming a blockage.

[0029] Working principle of this utility model:

[0030] The utility model is a hydrocyclone that is easy to feed. When the device is in use, the external sewage inlet pipe is connected to the feed pipe 14 and the branch feed pipe 15. Since the surfaces of the feed pipe 14 and the branch feed pipe 15 are both set to be conical, a gradually expanding feed pipe structure is adopted. The inlet ends of the feed pipe 14 and the branch feed pipe 15 are small, and the outlet ends gradually expand. The connecting plate 12 and the fixed frame 11 are connected by bolts, and then the installation is completed;

[0031] The sewage enters the interior of the feed pipe 2 through the feed pipe 14 and the branch feed pipe 15, and is then transported to the interior of the vortex body 1 through the feed pipe 2. The feed pipe 14 and the branch feed pipe 15 can gradually reduce the flow rate of the sewage when it enters the vortex body 1, reducing the impact on the internal flow field of the vortex body 1. At the same time, the fluid can enter the vortex body 1 more smoothly. The feeding direction of the branch feed pipe 15 is consistent with the tangential rotation direction in the vortex body 1. In this way, the material can enter the vortex body 1 more evenly, avoiding the flow field turbulence caused by excessive feed flow from a single inlet.

[0032] Since solid particles and liquids have different densities, they are subjected to different centrifugal forces. After the sewage enters the vortex body 1, a rotating flow field is quickly formed, and the tangential velocity gradually decreases from the wall surface of the vortex body 1 to the center. In the area close to the wall surface, the tangential velocity is relatively large, and then passes through the upper vertebra 16, the middle vertebra 17 and the lower vertebra 18. In the high-speed rotating flow field, due to the gradual decrease in diameter, the rotation radius decreases, thereby increasing the centrifugal force, which is conducive to further separating the solid particles from the liquid. The solid particles with larger density are subjected to a larger centrifugal force and are thrown to the wall of the device, and spiral downward along the inner wall of the upper vertebra 16, the middle vertebra 17 and the lower vertebra 18, and are finally discharged from the sand settling mouth 19. In addition, the splash guard 21 at the bottom effectively prevents fixed impurities from splashing, and the splash guard 21 is always rubbed with the fixed impurities and is easily worn. Rotating the splash guard 21 drives the splash guard 21 to separate from the threaded groove 20, thereby removing the splash guard 21 for replacement, which is convenient and quick to operate.

[0033] The liquid with lower density forms an inner vortex and moves toward the center, passes through the anti-blocking grille 22 and then flows into the overflow pipe 6. The mesh size of the grille is determined according to the size of the particles to be separated. It is necessary to prevent large particles from entering the overflow pipe 6 and causing blockage, while ensuring that the fluid can flow out smoothly. At the same time, the surface of the anti-blocking grille 22 is set to be conical, so that impurities filtered on the surface can be discharged smoothly by gravity, avoiding entering the overflow pipe 6 and causing blockage.

[0034] When it is necessary to adjust the depth of the overflow pipe 6 inside the straight cylindrical body 10, first pull the U-shaped block 5 outward, thereby driving the U-shaped block 5 to separate from the fixed groove 4 and the clamping groove 7, thereby moving the overflow pipe 6 up and down to adjust the overflow pipe 6, and then making the overflow pipe 6 move inside the fixed pipe 3. After determining the position, insert the U-shaped block 5 into the clamping groove 7 at the appropriate position, and enter the fixed groove 4 for fixation, and then the adjustment is completed. The position of the overflow pipe 6 can be flexibly adjusted to control the overflow flow rate and particle size.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
