Description

Technical Field

[0001] The utility model relates to the technical field of cyclones, in particular to a hydrocyclone classification device. Background Art

[0002] A hydrocyclone is a grading device that uses centrifugal force to accelerate the settling of ore particles. It requires pressure to feed the ore, so it consumes a lot of power. However, it occupies a small area, is inexpensive, has a large processing capacity, and has high grading efficiency, producing a very fine overflow product.

[0003] A Chinese patent application, CN220386843U, discloses a hydrocyclone classification device with a filing date of July 19, 2023. The patented technology allows materials to enter the device through the use of a feed port, wherein a servo motor drives the screw to rotate, and then a movable block on the screw is limited by a limit block and a limit groove, so that the movable block can move on the screw. While moving, the movable block drives the baffle in the feed port to move through the connecting block, which can adjust the size of the feed port, thereby controlling the feed flow rate and preventing the large feed flow from causing wear on the internal part of the device. This can reduce the degree of wear on the device and help extend its service life. However, the baffle that moves up and down in the above-mentioned device usually needs to be used in conjunction with components such as guide rails and transmission mechanisms, making the overall structure more complex, increasing manufacturing costs and maintenance difficulties, and requiring sufficient vertical space to accommodate the movement trajectory of the baffle, which may limit the application of the device in certain space-constrained environments. Therefore, the inventors provide a hydrocyclone classification device to solve the problems raised in the above-mentioned background technology. Summary of the Invention

[0004] The purpose of the utility model is to provide a hydrocyclone classification device, which can achieve the effect of facilitating maintenance of the adjustment mechanism and saving space.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A hydrocyclone classification device comprises a cyclone cylinder, the bottom of which is fixedly connected to a conical cylinder via a connecting flange, the left side of the cyclone cylinder being fixedly connected to a feed pipe, the top of the cyclone cylinder being fixedly connected to an overflow pipe, an adjustment mechanism being provided inside the feed pipe; the adjustment mechanism comprising a rotating rod rotatably connected to the upper and lower sides of the feed pipe, the top of the rotating rod penetrating the surface of the feed pipe, and a rotating seal being provided on the rotating rod at the penetration point; a baffle being fixedly connected to the surface of the rotating rod; a gear being fixedly connected to the top of the rotating rod, the rear side of the gear being engaged with a toothed plate that can move left and right; and a filtering mechanism being provided at the top of the overflow pipe.

[0007] As a further solution of the present invention: the top of the feed pipe is fixedly connected to a base, the left side of the base is fixedly connected to a cylinder, and the output end of the cylinder is fixedly connected to a tooth plate.

[0008] As a further solution of the present invention: the baffle is made of a wear-resistant and impact-resistant alloy material.

[0009] As a further solution of the present invention: the filtering mechanism includes a docking tube, a filter screen is arranged inside the docking tube, a plug-in ring is fixedly connected to the bottom of the docking tube, a group of sliding grooves are opened inside the plug-in ring, a movable positioning block is slidably connected inside the sliding groove, a support spring is fixedly connected to the outer side of the positioning block, and the other side of the support spring is fixedly connected to the sliding groove; a group of positioning grooves are opened on the outer side of the top of the overflow pipe.

[0010] As a further solution of the present invention: the outer side of the plug-in ring is slidably connected to a sliding ring, and the inside of the sliding ring is fixedly connected to a group of linkage ropes, the linkage ropes pass through the surface of the plug-in ring, and the connection surface of the linkage ropes and the plug-in ring is slidably connected; the inner side of the linkage ropes is fixedly connected to the corresponding positioning block.

[0011] As a further solution of the present invention: a sealing ring is fixedly connected to the bottom of the butt joint.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The hydrocyclone classification device starts the cylinder through an external power supply. The output end of the cylinder drives the tooth plate to move left and right, thereby driving the rotating rod to rotate through the transmission of the tooth plate and the gear. When the output end of the cylinder moves to the right, the rotating rod rotates clockwise, thereby driving the baffle to flip in the same direction, slowly revealing the cross-section of the feed pipe at this point, increasing the inflow of material. On the basis of the above, when the output end of the cylinder moves to the left, it will drive the baffle to flip counterclockwise, gradually reducing the exposed cross-section of the feed pipe at this point, thereby reducing the inflow of material, thereby achieving the effect of controlling the material flow. The flip-positioned baffle design is relatively simple and easy to manufacture and maintain. This design not only reduces manufacturing costs, but also reduces the possibility of malfunctions. In addition, the flipping action of the baffle mainly occurs in a two-dimensional plane, so it will not significantly increase the space occupied by the equipment in the vertical direction. Thus, the adjustment mechanism is easy to maintain and save space.

[0014] In addition, the hydrocyclone grading device pulls the sliding ring upward, and the sliding ring moves to drive a group of linkage ropes to move upward, thereby driving a group of positioning blocks to slide into the sliding groove until they are immersed in the sliding groove, so that the support spring is compressed, and then the plug-in ring is aligned with the position and plugged into the top of the overflow pipe. Finally, the sliding ring is released, so that the support spring rebounds and drives the sliding ring and the positioning block to return to their original position. At the same time, the positioning block is inserted into the corresponding positioning groove, thereby achieving the effect of installing the filtering mechanism. The liquid discharged through the overflow pipe will be discharged into the inside of the docking pipe, filtered by the filter screen, and then the liquid material will be discharged, thereby achieving the effect of further separating the material.

DETAILED DESCRIPTION

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0021] like Figure 1 、 2 As shown, a hydrocyclone classifier includes a cyclone barrel 10. The bottom of the cyclone barrel 10 is fixedly connected to a conical barrel 12 via a connecting flange 11. A feed pipe 13 is fixedly connected to the left side of the cyclone barrel 10, and an overflow pipe 14 is fixedly connected to the top of the cyclone barrel 10. An adjustment mechanism 20 is provided inside the feed pipe 13.

[0022] During operation, a solid-liquid mixture enters the cyclone barrel 10 through the feed pipe 13, forming a rotating liquid column within the cyclone. During this rotation, solid particles in the liquid are subjected to centrifugal force, resulting in different motion paths. Heavy solid particles (or those with higher density) are flung toward the outer wall of the cyclone due to the greater centrifugal force, moving downward along the outer wall and ultimately exiting the bottom of the conical barrel 12. Light liquid (or those with lower density) flows toward the center and exits through the overflow pipe 14, achieving a graded discharge effect.

[0023] refer to Figure 1 、 3 The adjustment mechanism 20 includes a rotating rod 201 rotatably connected to the upper and lower sides of the feed pipe 13. The top of the rotating rod 201 penetrates the surface of the feed pipe 13, and a rotating seal is provided on the rotating rod 201 at the penetration point. A baffle 202 is fixedly connected to the surface of the rotating rod 201. A gear 203 is fixedly connected to the top of the rotating rod 201, and a toothed plate 204 that can move left and right is engaged with the rear side of the gear 203.

[0024] Specifically, the top of the feed pipe 13 is fixedly connected to a base 206 , the left side of the base 206 is fixedly connected to a cylinder 205 , and the output end of the cylinder 205 is fixedly connected to the tooth plate 204 .

[0025] Preferably, the baffle 202 is made of a wear-resistant and impact-resistant alloy material. When in use, the cylinder 205 is started by an external power supply, and the output end of the cylinder 205 drives the tooth plate 204 to move left and right, thereby driving the rotating rod 201 to rotate through the transmission of the tooth plate 204 and the gear 203. When the output end of the cylinder 205 moves to the right, the rotating rod 201 rotates clockwise, thereby driving the baffle 202 to flip in the same direction, slowly exposing the cross-section of the feed pipe 13 at this point, increasing the inflow rate of the material. When the leftmost end of the front face of the tooth plate 204 contacts the surface of the gear 203, the baffle 202 flips 90 degrees, thereby achieving the effect of limiting the flipping angle of the baffle 202. On the basis of the above, when the output end of the cylinder 205 moves to the left, it will drive the baffle 202 to flip clockwise, gradually reducing the exposed cross-section of the feed pipe 13 at this point, thereby reducing the inflow rate of the material. When the rightmost end of the tooth plate 204 contacts the surface of the gear 203, the baffle 202 returns to its original position, thereby achieving the effect of controlling the material flow rate. Since the present mechanism can flexibly adjust the opening of the feed pipe 13 by flipping and positioning the baffle 202, thereby changing the effective cross-sectional area of the feed pipe 13. This design allows the operator to quickly and accurately adjust the feed amount according to different material properties and separation requirements, thereby improving the adaptability and flexibility of the equipment. Secondly, compared with some complex adjustment devices, the flip-positioned baffle 202 is relatively simple in design and easy to manufacture and maintain. This design not only reduces manufacturing costs, but also reduces the possibility of failure, thereby improving the reliability and service life of the equipment. Moreover, compared with the reference document, the up-and-down moving blocking plate needs to maintain a good seal with the feed port during movement, which places higher requirements on the sealing structure and materials, making the mechanism more expensive and more space-consuming. However, while ensuring sealing, the present device does not significantly increase the space occupied by the equipment in the vertical direction because the flipping action of the baffle 202 mainly occurs on a two-dimensional plane.

[0026] During the material separation process of the above device, the liquid discharged from the overflow pipe 14 still contains some fixed particles and impurities. In order to ensure the cleanliness of the liquid discharged from the overflow pipe 14, a filtering mechanism 30 is proposed.

[0027] refer to Figure 2 、 4 The filtering mechanism 30 includes a docking tube 301 provided at the top of the overflow pipe 14, a filter screen 302 is provided inside the docking tube 301, a plug-in ring 303 is fixedly connected to the bottom of the docking tube 301, a group of sliding grooves 304 are opened inside the plug-in ring 303, and a movable positioning block 305 is slidably connected inside the sliding groove 304. A support spring 306 is fixedly connected to the outside of the positioning block 305, and the other side of the support spring 306 is fixedly connected to the sliding groove 304; a group of positioning grooves 309 are opened on the outside of the top of the overflow pipe 14.

[0028] Specifically, the outer side of the plug-in ring 303 is slidably connected to a sliding ring 307, and the inside of the sliding ring 307 is fixedly connected to a group of connecting ropes 308. The connecting ropes 308 pass through the surface of the plug-in ring 303, and the connecting ropes 308 are slidably connected to the surface of the connection between the plug-in ring 303; the inner side of the connecting rope 308 is fixedly connected to the corresponding positioning block 305.

[0029] When in use, the sliding ring 307 is pulled upward, and the sliding ring 307 moves to drive a group of linkage ropes 308 to move upward, thereby driving a group of positioning blocks 305 to slide into the sliding groove 304 until they are immersed in the sliding groove 304, so that the support spring 306 is compressed, and then the plug-in ring 303 is aligned with the position and inserted into the top of the overflow pipe 14, and finally the sliding ring 307 is released, so that the support spring 306 rebounds and drives the sliding ring 307 and the positioning block 305 to return to their original position, and at the same time the positioning block 305 is inserted into the corresponding positioning groove 309, thereby achieving the effect of installing the filter mechanism 30, so that the liquid discharged through the overflow pipe 14 will be discharged into the docking pipe 301, filtered by the filter mesh 302, and then the liquid material will be discharged, thereby achieving the effect of further separating the material.

[0030] Preferably, a sealing ring 310 is fixedly connected to the bottom of the butt joint 301; after the filter mechanism 30 is installed, the sealing ring 310 is tightly attached to the mouth of the overflow pipe 14, thereby achieving a sealing effect on the pipe connection.

[0031] The working principle of the present invention is as follows: the cylinder 205 is started by an external power supply, and the output end of the cylinder 205 drives the gear plate 204 to move left and right, thereby driving the rotating rod 201 to rotate through the transmission of the gear plate 204 and the gear 203. When the output end of the cylinder 205 moves to the right, the rotating rod 201 rotates clockwise, thereby driving the baffle 202 to flip in the same direction, slowly exposing the cross-section of the feed pipe 13 at this point, increasing the inflow rate of the material, and when the leftmost end of the front side of the gear plate 204 contacts the surface of the gear 203, the baffle 202 flips 90 degrees, thereby achieving the effect of limiting the flipping angle of the baffle 202. On the basis of the above, when the output end of the cylinder 205 moves to the left, it will drive the baffle 202 to flip counterclockwise, gradually reducing the exposed cross-section of the feed pipe 13 at this point, thereby reducing the inflow rate of the material, and when the rightmost end of the gear plate 204 contacts the surface of the gear 203, the baffle 202 returns to its original position, thereby achieving the effect of controlling the material flow rate.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
