Description

Technical Field

[0001] This utility model relates to the field of desander cone tube technology, specifically an adjustable angle desander cone tube assembly. Background Technology

[0002] The conical tube assembly of the desander is the core component of the hydrocyclone desander, primarily used for solid-liquid separation via centrifugal force. Its structural design and material selection directly affect the desander efficiency and equipment lifespan. Sand-laden fluid enters the separator tangentially, forming a high-speed vortex. Under centrifugal force, denser sand particles are thrown against the inner wall of the conical tube and slide down the conical surface, eventually settling in the sand reservoir; lighter fluid spirals upward and is discharged through the overflow pipe. The conical shape of the tube gradually reduces the fluid's radius of rotation and increases the tangential velocity, further enhancing the separation effect.

[0003] In existing technologies, such as the adjustable double-cone hydrocyclone disclosed in CN205815936U, the hydrocyclone body comprises a hydrocyclone body consisting of a straight cylinder and a conical cylinder connected together, and an overflow port, a feed port, and a bottom flow port arranged sequentially from top to bottom on the hydrocyclone body. The conical cylinder is formed by two frustum-shaped cones I and II with progressively decreasing cone angles, spliced ​​together in the same direction from top to bottom. A protective tube is slidably fitted on the bottom flow port. This protective tube is a cylindrical tube with a central through hole, and the inner diameter of the central through hole gradually increases from top to bottom. It improves the classification and separation efficiency through the double-cone structure of the conical cylinder, and the increased inner diameter of the tube at the bottom flow port by the protective tube effectively alleviates the spiral scattering state when the heavy medium flows out.

[0004] Existing conical tube assemblies improve grading and sorting efficiency through the double-cone structure of the conical tube body. The flow-protecting pipe increases the inner diameter of the tube body at the bottom outlet, effectively mitigating the spiral scattering state when the heavy medium flows out. However, it is inconvenient to adjust the angle during use. The swirling flow field parameters of the fixed-angle conical tube are a single preset value, which can only match the separation requirements of sand particles of a specific size. For fine-sized sand, the centrifugal force of the fixed flow field is insufficient to push the sand particles to migrate towards the wall, resulting in the fine sand being discharged with the overflow liquid, and the separation efficiency is low. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology has the problems of inconvenience in adjusting the angle during use, the swirling flow field parameters of the fixed-angle cone tube are a single preset value, which can only match the separation needs of sand particles of a specific size. For fine-sized sand particles, the centrifugal force of the fixed flow field is insufficient to push the sand particles to migrate towards the wall, resulting in the fine sand being discharged with the overflow liquid and the separation efficiency being low.

[0007] To achieve the above objectives, this utility model provides the following technical solution: An adjustable-angle sand remover cone tube assembly includes: a cone tube body, a hydrocyclone body, a fixing plate, and a fixing shaft; the hydrocyclone body is welded and fixed to the upper surface of the cone tube body, the fixing plate is welded and fixed to the outer surface of the hydrocyclone body, and the fixing shaft is fixed to one side of the fixing plate. It also includes: An adjusting component and a sand removal component; the adjusting component is located on the other side of the fixed plate, and the sand removal component is located inside the conical tube.

[0008] As a further embodiment of this utility model: the adjustment assembly includes: a fixed frame, a stepper motor, an active helical gear, a driven helical gear, a fixed ring, a limiting hole, a mounting plate, a fixed block, a compression spring, and an electromagnet. Two fixed frames are provided, and both fixed frames are welded to both ends of the fixed plate. One of the fixed frames has a stepper motor fixed to its side wall by screws.

[0009] As a further embodiment of this utility model: the power output shaft of the stepper motor is fixed with an active helical gear, and a driven helical gear meshes with one side of the active helical gear. The driven helical gear is rotatably connected to the fixed plate through a rotating shaft.

[0010] As a further improvement of this utility model: a fixing ring is integrally fixed to the outer wall of the driven helical tooth, and a plurality of limiting holes are equidistantly opened on the side wall of the fixing ring.

[0011] As a further embodiment of this utility model: an mounting plate is welded and fixed to the upper surface of the fixing frame, a fixing block is telescopically connected to the right side of the mounting plate, a compression spring abuts against the side wall of the fixing block and is connected to the mounting plate, and an electromagnet is fixed to the left side of the mounting plate and is telescopically connected to the fixing block.

[0012] As a further embodiment of this utility model: the sand removal assembly includes: auxiliary swirl plates, spiral dividing ribs, water outlet pipe, feed pipe, elastic discharge pipe and storage box. There are three auxiliary swirl plates, all of which are installed inside the hydrocyclone body. The inner walls of the three auxiliary swirl plates are all fixed with water outlet pipes.

[0013] As a further embodiment of this utility model: the inner surface of the conical tube is fixed with a spiral dividing rib, and the outer surface of the hydrocyclone body is connected to a feed pipe.

[0014] As a further embodiment of this utility model: the lower surface of the conical tube is connected to an elastic discharge pipe, and the lower surface of the elastic discharge pipe is connected to a storage box.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a stepper motor to drive the active helical gear to rotate, which in turn meshes with the driven helical gear to rotate. This drives the cone tube to rotate. The fixed shaft ensures the stability of the cone tube and allows the angle of the cone tube to be adjusted, enabling the raw material inside the cone tube to migrate better to the wall, thereby improving the separation effect.

[0016] 2. The tapered tube structure of this utility model is thicker at the top and thinner at the bottom. As the fluid flows downward, the rotation speed increases sharply as the cross-sectional area of ​​the tapered tube decreases, forming a speed gradient that is gentler at the top and steeper at the bottom. Since the density of sand particles is much greater than that of the fluid, they will be subjected to greater centrifugal force in the high-speed swirling flow and will be thrown towards the inner wall of the tapered tube, forming an outer swirling flow that moves along the inner wall. The spiral separating ribs on the inner wall of the tapered tube can play an auxiliary separation role. Attached Figure Description

[0019] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0022] Example 1: Please see Figure 1 - Figure 5 This is the first embodiment of the present utility model. This embodiment provides an adjustable angle sand remover cone tube assembly, including: a cone tube body 1, a hydrocyclone body 2, a fixing plate 3, and a fixing shaft 6; the hydrocyclone body 2 is welded and fixed to the upper surface of the cone tube body 1, the fixing plate 3 is welded and fixed to the outer surface of the hydrocyclone body 2, and the fixing shaft 6 is fixed to one side of the fixing plate 3, and also includes: Adjustment component and sand removal component; the adjustment component is located on the other side of the fixed plate 3, and the sand removal component is located inside the cone tube 1.

[0023] Specifically, the adjustment components include: a fixed frame 4, a stepper motor 41, an active helical gear 42, a driven helical gear 43, a fixing ring 44, a limiting hole 45, a mounting plate 46, a fixing block 47, a compression spring 48, and an electromagnet 49. There are two fixed frames 4, and both fixed frames 4 are welded to both ends of the fixed plate 3. The side wall of one of the fixed frames 4 is fixed with a stepper motor 41 by screws. The power output shaft of the stepper motor 41 is fixed with an active helical gear 42. One side of the active helical gear 42 is engaged with a driven helical gear 43. The driven helical gear 43 is rotatably connected to the fixed plate 3 through a rotating shaft.

[0024] Furthermore, the stepper motor 41 drives the active helical gear 42 to rotate, which in turn meshes with the driven helical gear 43 to rotate, thus driving the conical tube 1 to rotate. The fixed shaft 6 ensures the stability of the conical tube 1, thereby adjusting the angle of the conical tube 1 so that the raw material inside the conical tube 1 can migrate better to the wall.

[0025] Specifically, a retaining ring 44 is integrally fixed to the outer wall of the driven helical tooth 43, and a plurality of limiting holes 45 are equidistantly opened on the side wall of the retaining ring 44. Furthermore, when the electromagnet 49 is energized, it attracts the fixing block 47, causing the end of the fixing block 47 to separate from the limiting hole 45, thus releasing the fixing ring 44.

[0026] Specifically, a mounting plate 46 is welded and fixed to the upper surface of the mounting bracket 4. A fixing block 47 is telescopically connected to the right side of the mounting plate 46. A compression spring 48 abuts against the side wall of the fixing block 47 and is connected to the mounting plate 46. An electromagnet 49 is fixed to the left side of the mounting plate 46 and is telescopically connected to the fixing block 47.

[0027] Furthermore, after the electromagnet 49 is closed, the compression spring 48 will push the fixing block 47 to reset under its own elasticity, thereby limiting the fixing ring 44.

[0028] In use, the conical tube 1 is first placed in a suitable position. The stability of the component is ensured by the fixing bracket 4 set on the fixing plate 3. When the angle of the conical tube 1 needs to be adjusted, the electromagnet 49 set on the mounting plate 46 is energized to attract the fixing block 47, so that the end of the fixing block 47 is separated from the limiting hole 45, releasing the fixing ring 44. When the fixing block 47 moves, it pushes the compression spring 48 to compress. At this time, the stepper motor 41 drives the active helical gear 42 to rotate, which in turn meshes with the driven helical gear 43 to rotate. This drives the conical tube 1 to rotate. The fixed shaft 6 set can ensure the stability of the conical tube 1, thereby adjusting the angle of the conical tube 1 so that the raw material inside the conical tube 1 can better migrate to the wall, thereby improving the separation effect.

[0029] In summary, when the adjustable angle sand separator cone tube assembly is in use, the stepper motor 41 drives the active helical gear 42 to rotate, which in turn meshes with the driven helical gear 43 to rotate. This drives the cone tube body 1 to rotate. The fixed shaft 6 ensures the stability of the cone tube body 1, thereby adjusting the angle of the cone tube body 1 so that the raw material inside the cone tube body 1 can migrate better to the wall surface, thus improving the separation effect.

[0030] Example 2: Please see Figure 1 - Figure 4 This is the second embodiment of the present utility model.

[0031] Specifically, the sand removal assembly includes: auxiliary swirl plate 5, spiral dividing rib 51, water outlet pipe 52, feed pipe 53, elastic discharge pipe 54 and storage box 55. There are three auxiliary swirl plates 5, all of which are installed inside the hydrocyclone body 2. The inner walls of the three auxiliary swirl plates 5 are all fixed with water outlet pipes 52.

[0032] Furthermore, the raw material enters the hydrocyclone body 2 through the feed pipe 53. With the assistance of the auxiliary cyclone plate 5, the raw material enters the interior and spirals downward along the inner wall of the hydrocyclone body 2.

[0033] Specifically, the inner surface of the cone tube 1 is fixed with a spiral dividing rib 51, the outer surface of the hydrocyclone body 2 is connected to a feed pipe 53, the lower surface of the cone tube 1 is connected to an elastic discharge pipe 54, and the lower surface of the elastic discharge pipe 54 is connected to a storage box 55.

[0034] Furthermore, due to the structure of the tapered tube 1, which is thicker at the top and thinner at the bottom, the rotational speed of the fluid increases sharply as the cross-sectional area of ​​the tapered tube 1 decreases during downward flow, forming a velocity gradient that is gentler at the top and steeper at the bottom. Since the density of sand particles is much greater than that of the fluid, they will be subjected to greater centrifugal force in the high-speed swirling flow and will be thrown towards the inner wall of the tapered tube 1, forming an outer swirling flow that moves along the inner wall.

[0035] In use, by connecting the feed pipe 53 to an external conveying device, the raw material enters the hydrocyclone body 2 through the feed pipe 53. With the assistance of the auxiliary cyclone plate 5, the raw material enters the interior and spirals downward along the inner wall of the hydrocyclone body 2, and then enters the cone tube 1 for separation. Due to the structure of the cone tube 1, which is thicker at the top and thinner at the bottom, the rotation speed increases sharply as the cross-sectional area of ​​the cone tube 1 decreases during the downward flow of the fluid, forming a speed gradient that is gentler at the top and steeper at the bottom. Since the density of sand particles is much greater than that of the fluid, they will be subjected to greater centrifugal force in the high-speed cyclone and will be thrown towards the inner wall of the cone tube 1, forming an outer cyclone that moves along the inner wall. The cleaner fluid with lower density gathers towards the center of the cone tube 1, forming an inner cyclone that spirals upward and is discharged through the outlet pipe 52. The spiral separating ribs 51 on the inner wall of the cone tube 1 can play an auxiliary separation role. The separated sand particles enter the storage tank 55 for collection through the elastic discharge pipe 54.

[0036] In summary, when the adjustable angle sand separator cone assembly is in use, the stepper motor 41 drives the active helical gear 42 to rotate, which in turn meshes with the driven helical gear 43 to rotate. This drives the cone body 1 to rotate. The fixed shaft 6 ensures the stability of the cone body 1, thereby adjusting the angle of the cone body 1. This allows the raw material inside the cone body 1 to migrate better towards the wall, thus improving the separation effect. Furthermore, the cone body 1 has a structure that is wider at the top and narrower at the bottom. As the fluid flows downward, the rotational speed increases sharply as the cross-sectional area of ​​the cone body 1 decreases, forming a speed gradient that is gentler at the top and steeper at the bottom. Since the density of sand particles is much greater than that of the fluid, they will be subjected to greater centrifugal force in the high-speed swirling flow and will be thrown towards the inner wall of the cone body 1, forming an outer swirling flow that moves along the inner wall. The spiral separating ribs 51 on the inner wall of the cone body 1 can play an auxiliary separation role.
