Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of hydrocyclone technology, and more specifically, to an adjustable flat-bottom hydrocyclone. Background Technology

[0002] In many industrial sectors, such as mining, petrochemicals, and wastewater treatment, hydrocyclones are widely used as a highly efficient separation device. Traditional hydrocyclones are usually based on the principle of centrifugal sedimentation, using the centrifugal force generated by the high-speed rotation of materials inside the hydrocyclone to separate materials of different densities or particle sizes. Their structure is generally relatively fixed, mainly consisting of a feed inlet, a cylinder, a cone, an overflow outlet, and an underflow outlet. Under relatively stable operating conditions, traditional hydrocyclones can achieve good separation results, providing important support for industrial production.

[0003] According to the published flat-bottom hydrocyclone (publication number: CN200945461Y), it has a shell, a feed pipe in the tangential direction on one side of the shell, and an overflow pipe above the shell. The feature is that there is a cylindrical tube below the shell, and a bottom cover below the cylindrical tube, with a bottom flow port (sand settling port) on the bottom cover. This utility model replaces the traditional conical tube with a cylindrical tube structure below the shell. When processing high-concentration, coarse, and heavy materials, it eliminates the accumulation of coarse and heavy materials in the tube, reduces overflow of coarse materials and underflow (sand settling) of fine materials, and can improve classification efficiency and classification accuracy.

[0004] In the aforementioned application, the design of the central tube of the hydrocyclone in the prior art is a fixed connection that cannot be adjusted, which needs to be improved. Therefore, we propose an adjustable flat-bottom hydrocyclone. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide an adjustable flat-bottomed hydrocyclone, which solves the problem that the central tube cannot be adjusted in related technologies.

[0006] According to one aspect, at least one embodiment of this disclosure provides an adjustable flat-bottomed hydrocyclone, including a hydrocyclone, a separator disposed on the top of the hydrocyclone, a feed inlet opened on the top of the separator, a central tube slidably connected inside the feed inlet, and an adjustment mechanism disposed on the top of the hydrocyclone;

[0007] The adjusting mechanism includes a hollow plate, which is fixedly connected to the top of the hydrocyclone. A connecting shaft extends through the side of the hollow plate. A threaded rod is fixedly connected to the circumferential surface of the connecting shaft. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A connecting plate is fixedly connected to the top of the threaded sleeve. A clamping plate is fixedly connected to the rear side of the connecting plate. A hollow block is fixedly connected to the top of the clamping plate. A spring is fixedly connected to the inner wall of the hollow block. A sliding plate is fixedly connected to the end of the spring away from the hollow block. A connecting block is fixedly connected to the side of the sliding plate. A reinforcing plate is fixedly connected to the side of the connecting block.

[0008] For example, in at least one embodiment of this disclosure, an adjustable flat-bottomed hydrocyclone is provided, which further includes: a fixed shaft is fixedly connected to the circumferential surface of the connecting shaft, and a handle is fixedly connected to the circumferential surface of the fixed shaft. The handle is designed to facilitate operation by the operator when the threaded rod needs to be rotated.

[0009] The side section of the threaded sleeve is rectangular, and the threaded sleeve is slidably connected to the inner wall of the hollow plate. The side section of the connecting plate is L-shaped. The above design is beneficial to make the threaded sleeve move in a straight line and to limit the movement of the threaded sleeve.

[0010] The side section of the clamping plate is set as semi-circular, and the clamping plate is in contact with the circumferential surface of the central tube. The design of the clamping plate is advantageous because the central tube can be adjusted when the clamping plate no longer clamps the central tube.

[0011] The sliding plate is slidably connected to the inner wall of the hollow block, and the reinforcing plate is in contact with the circumferential surface of the central tube. The design of the reinforcing plate helps to enhance the clamping force on the central tube.

[0012] According to another aspect, at least one embodiment of this disclosure also provides an adjustable flat-bottomed hydrocyclone, including a damage prevention mechanism disposed inside the central tube. The damage prevention mechanism includes a protective plate disposed inside the central tube. The above design is beneficial to enhancing the stability of the torsion spring rod rotation.

[0013] For example, in at least one embodiment of this disclosure, an adjustable flat-bottomed hydrocyclone further includes: a fixing block fixedly connected to the inner side wall of the protective plate, a torsion spring rod rotatably connected to the inner side wall of the fixing block, a sleeve fixedly connected to the circumferential surface of the torsion spring rod, and a speed reduction plate fixedly connected to the circumferential surface of the sleeve. The above design is beneficial for decelerating large impurities during their fall.

[0014] The side cross-section of the fixed block is concave, which enhances the stability of the speed reducer's movement.

[0015] The number of the damage prevention mechanisms is set to multiple, and they are arranged in a circumferential array on the inner wall of the protective plate. This design helps to enhance the range of protection.

[0016] The protective plate has a semi-circular side section and is in contact with the top of the central tube. This design is beneficial for protecting the central tube.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] 1. In this utility model, the rotational force of the connecting shaft drives the threaded rod, threaded sleeve, connecting plate, clamping plate, fixed shaft, handle, hollow block, spring, sliding plate, connecting block, reinforcing plate and other components to cooperate with each other, so as to realize the rotation of the handle fixed on the circumference of the fixed shaft, thereby driving the fixed shaft to rotate. The rotation of the fixed shaft drives the connecting shaft through the side of the hollow plate to rotate, and at the same time drives the threaded rod fixed on the circumference of the connecting shaft to rotate. The rotation of the threaded rod causes the two threaded sleeves connected to the circumference to move linearly away from each other on the inner side wall of the hollow plate. When the central tube needs to be adjusted, it is convenient for the staff to make timely adjustments.

[0019] 2. In this utility model, the rotational force of the torsion spring rod drives the protective plate, the fixing block, the sleeve, the deceleration plate and other components to cooperate with each other. When the worker pours the material through the central tube, the material contacts the deceleration plate fixed on the circumference of the sleeve during the falling process, thereby causing the torsion spring rod rotating on the inner side wall of the fixing block to rotate. At the same time, it drives the sleeve fixed on the circumference of the torsion spring rod to rotate. During the material feeding process, the falling speed of large impurities is reduced, and damage to the inside of the hydrocyclone is avoided. Attached Figure Description

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0030] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, it illustrates an adjustable flat-bottomed hydrocyclone according to an embodiment of the present disclosure, including a hydrocyclone 1, a separator 2 provided on the top of the hydrocyclone 1, a feed inlet 3 opened on the top of the separator 2, a central tube 4 slidably connected inside the feed inlet 3, and an adjustment mechanism 5 provided on the top of the hydrocyclone 1.

[0034] The adjusting mechanism 5 includes a hollow plate 51, which is fixedly connected to the top of the hydrocyclone 1. A connecting shaft 52 extends through the side of the hollow plate 51. A threaded rod 53 is fixedly connected to the circumferential surface of the connecting shaft 52. A threaded sleeve 54 is threadedly connected to the circumferential surface of the threaded rod 53. A connecting plate 55 is fixedly connected to the top of the threaded sleeve 54. A clamping plate 56 is fixedly connected to the rear side of the connecting plate 55. A hollow block 59 is fixedly connected to the top of the clamping plate 56. A spring 510 is fixedly connected to the inner wall of the hollow block 59. A sliding plate 511 is fixedly connected to the end of the spring 510 away from the hollow block 59. A connecting block 512 is fixedly connected to the side of the sliding plate 511. A reinforcing plate 513 is fixedly connected to the side of the connecting block 512.

[0035] In some examples, the circumferential surface of the connecting shaft 52 is fixedly connected to a fixed shaft 57, and the circumferential surface of the fixed shaft 57 is fixedly connected to a handle 58. The handle 58 is designed to facilitate operation by the operator when the threaded rod 53 needs to be rotated.

[0036] The side section of the threaded sleeve 54 is set to a rectangle. The threaded sleeve 54 is slidably connected to the inner side wall of the hollow plate 51. The side section of the connecting plate 55 is set to an L shape. The above design is beneficial to make the threaded sleeve 54 move in a straight line and to limit the threaded sleeve 54.

[0037] The side section of the clamping plate 56 is set as semi-circular. The clamping plate 56 is in contact with the circumferential surface of the central tube 4. The design of the clamping plate 56 is advantageous because the central tube 4 can be adjusted when the clamping plate 56 no longer clamps the central tube 4.

[0038] The sliding plate 511 is slidably connected to the inner wall of the hollow block 59, and the reinforcing plate 513 is in contact with the circumferential surface of the central tube 4. The design of the reinforcing plate 513 is conducive to enhancing the clamping force on the central tube 4.

[0039] For example, such as Figures 1-5 As shown, when the central tube 4 needs adjustment, the operator rotates the handle 58 fixed to the circumference of the fixed shaft 57, thereby causing the fixed shaft 57 to rotate. The rotation of the fixed shaft 57 causes the connecting shaft 52, which passes through the side of the hollow plate 51, to rotate. At the same time, it causes the threaded rod 53 fixed to the circumference of the connecting shaft 52 to rotate. The rotation of the threaded rod 53 causes the two threaded sleeves 54, which are threaded to the circumference, to move linearly away from each other on the inner side wall of the hollow plate 51. When the threaded sleeves 54 move, they cause the connecting plate 55 fixed to the top to move. The movement of the connecting plate 55 causes the clamping plate 56 fixed to the rear side to move. The central tube 4 is no longer clamped. When the clamping plate 56 moves, it drives the hollow block 59 fixed at the top to move. The movement of the hollow block 59 drives the sliding plate 511 sliding on the inner wall to move, and at the same time drives the connecting block 512 fixed on the side of the sliding plate 511 to move. This causes the reinforcing plate 513 fixed on the side of the connecting block 512 to move and no longer contact the central tube 4. At this time, the operator adjusts the depth of the central tube 4 entering the hydrocyclone 1. After the adjustment is completed, the operator rotates the handle 58 in the opposite direction, so that the clamping plate 56 and the reinforcing plate 513 contact the central tube 4 and clamp the central tube 4.

[0040] like Figures 1-5 As shown, it illustrates an adjustable flat-bottomed cyclone separator in another embodiment of this disclosure, which is largely the same as the technical solution of embodiment 1. Therefore, only the differences are described, including the fact that the center tube 4 is provided with an anti-damage mechanism 6, which includes a protective plate 61. The protective plate 61 is provided inside the center tube 4. The above design is beneficial to enhancing the stability of the rotation of the torsion spring rod 63.

[0041] In some examples, the design also includes: a fixing block 62 is fixedly connected to the inner wall of the protective plate 61, a torsion spring rod 63 is rotatably connected to the inner wall of the fixing block 62, a sleeve 64 is fixedly connected to the circumferential surface of the torsion spring rod 63, and a speed reduction plate 65 is fixedly connected to the circumferential surface of the sleeve 64. The above design is beneficial for slowing down large impurities during their fall.

[0042] The side section of the fixed block 62 is set to be concave, and the above design helps to enhance the stability of the movement of the speed reducer 65.

[0043] The number of damage prevention mechanisms 6 is set to multiple and arranged in a circumferential array on the inner wall of the protective plate 61. This design helps to enhance the range of protection.

[0044] The protective plate 61 has a semi-circular side section and is in contact with the top of the central tube 4. This design is beneficial for protecting the central tube 4.

[0045] For example, such as Figures 1-5 As shown, when the staff pours the material in through the central tube 4, the material contacts the deceleration plate 65 fixed on the circumferential surface of the sleeve 64 during its fall, which causes the torsion spring rod 63 rotating on the inner side wall of the fixed block 62 to rotate. At the same time, it drives the sleeve 64 fixed on the circumferential surface of the torsion spring rod 63 to rotate. When the sleeve 64 rotates, it causes the deceleration plate 65 fixed on the circumferential surface to move downward in an arc, thereby reducing the falling speed of the material and preventing damage to the inside of the hydrocyclone 1.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications or substitutions should be covered within the scope of the claims of this disclosure.
