Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sand discharge devices, and in particular to a vortex sand discharge device. Background Technology
[0002] A separator is a device that uses physical or chemical principles to separate different components in mixtures such as gas-liquid, liquid-liquid, solid-liquid, and gas-solid. It is typically equipped with a sand discharge device at its bottom: after the sand-containing liquid enters the separator, the solid particles settle into the sand collection hopper of the sand discharge device under gravity; to prevent solid particle deposition from affecting the normal operation of the sand discharge process, sand needs to be discharged periodically to reduce the amount of sand in the collection hopper.
[0003] Regarding the aforementioned sand removal technology, the inventors discovered that existing sand removal methods mostly employ high-pressure liquid to impact sand particles, causing them to flow out of the discharge port to achieve sand removal. However, the impact force of the high-pressure liquid on the sand collection area within the sand collection hopper has a relatively small coverage area, and sand particles in some blind spots cannot be completely discharged, resulting in a significant reduction in sand removal efficiency. Utility Model Content
[0004] The main technical problem solved by this utility model is to provide a vortex sand discharge device, which solves the problem of poor sand discharge effect.
[0005] To solve the above-mentioned technical problems, the present invention provides a cyclone sand discharge device, comprising: a sand collecting hopper, a flange plate 1 connected to the lower end of the sand collecting hopper, a flange plate 2 detachably connected to the lower surface of the flange plate 1, a sand discharge pipe assembly connected to the inner hole of the flange plate 2, a cyclone generator provided at the center of the sand collecting hopper, the cyclone generator comprising a fixed pipe body sealed at the upper end, a liquid guiding pipe body passing through the outer circular surface of the fixed pipe body, the liquid inlet direction of the liquid guiding pipe body being offset from the axis of the fixed pipe body, a central pipe concentrically connected to the top of the inner hole of the fixed pipe body, and a conical diffuser head located below the fixed pipe body connected to the lower end of the central pipe body;
[0006] The sand collecting hopper has a liquid inlet pipe through its circular wall. The inner end of the liquid inlet pipe is connected to flange plate three, and the outer end is connected to flange plate four. The end of the liquid guide pipe away from the fixed pipe body is connected to flange plate five. Flange plate five and flange plate three are connected by bolts.
[0007] By adopting the above technical solution, during use, the external high-pressure pipe body is connected to the flange plate of the inlet pipe at four-way joints, and the high-pressure liquid flows into the inner cavity of the fixed pipe body through the inlet pipe. Because the liquid inlet direction of the guide pipe body deviates from the axis of the fixed pipe body, the tangentially entering high-pressure liquid forms a swirling flow in the cavity and flows downward; after the swirling liquid contacts the conical diffuser head, it is guided by its conical surface to rotate and disperse in all directions, thereby driving the liquid in the sand collection hopper to rotate synchronously. The swirling effect allows the sand particles at the bottom of the sand collection hopper to be suspended and rotate with the liquid. At this time, opening the sand discharge pipe assembly can discharge the sand-containing liquid. This design can effectively avoid sand particle deposition that hinders sand discharge and significantly improve the sand discharge effect.
[0008] In a preferred embodiment, the present invention can be further configured as follows: the sand discharge pipe assembly includes a sand discharge pipe one and a sand discharge pipe two, the upper outer circle of the sand discharge pipe one is connected to the inner hole of the flange plate two, and the lower end is connected to the flange plate six; the lower end of the sand discharge pipe two is connected to a switch valve, and the upper end is connected to the flange plate seven; the flange plate seven and the flange plate six are connected by bolts.
[0009] By adopting the above technical solution, when the switch valve is opened, the sand-containing liquid in the sand collection hopper can flow out sequentially through the first and second sand discharge pipes to achieve the purpose of sand discharge; when the switch valve is closed, the liquid can be prevented from being discharged from the first and second sand discharge pipes, thereby achieving the effect of intermittent sand discharge.
[0010] In a preferred embodiment, the present invention can be further configured such that the lower end of the central tube extends below the fixed tube body, and the inner diameter of the fixed tube body is not less than 3 times the outer diameter of the central tube.
[0011] By adopting the above technical solution, the lower end of the central tube extends to the bottom of the fixed tube body, leaving sufficient space for liquid to flow out between the conical diffuser head and the fixed tube body; at the same time, the inner diameter of the fixed tube body is not less than 3 times the outer diameter of the central tube, ensuring that there is enough space between the outer circle of the central tube body and the inner wall of the fixed tube body, allowing the liquid to form a swirling flow and flow downward.
[0012] In a preferred embodiment, the present invention can be further configured such that: the end of the liquid guiding tube body located inside the fixed tube body is flush with the inner wall of the fixed tube body, and the liquid flowing into the liquid guiding tube body is located between the inner wall of the fixed tube body and the outer circle of the central tube.
[0013] By adopting the above technical solution, the liquid flowing into the liquid guide tube is located between the inner wall of the fixed tube and the outer circle of the central tube, so that the flowing liquid can form a stable vortex, thereby driving the sand particles in the sand collection hopper to suspend and rotate with the liquid, thus enhancing the sand discharge effect.
[0014] In a preferred embodiment, the present invention can be further configured such that the large-diameter end of the conical diffuser is not less than the inner diameter of the fixed tube.
[0015] By adopting the above technical solution, the large diameter end of the conical diffuser is not less than the inner diameter of the fixed pipe, and its conical surface can more fully guide the liquid to rotate and disperse in all directions, thereby allowing the sand particles in the sand collection hopper to rotate and suspend fully with the liquid.
[0016] In a preferred embodiment, the present invention can be further configured such that a swirling cavity is provided between the conical diffuser and the flange plate, and the height of the swirling cavity is not less than the outer diameter of the fixed pipe body.
[0017] By adopting the above technical solution, since there is a swirling cavity between the conical diffuser head and the flange plate, the liquid in the swirling cavity can rotate fully, thereby driving the sand particles at the bottom of the sand collection hopper to rotate and suspend.
[0018] In summary, this utility model has at least one of the following beneficial technical effects:
[0019] 1. By utilizing the tangential liquid inlet of the liquid guide tube and the space design of the fixed tube, a liquid vortex is efficiently formed, which can drive the liquid in the sand collection hopper to rotate synchronously, allowing the sand particles at the bottom to be fully suspended and avoiding sedimentation and blockage.
[0020] 2. Combined with the flow guiding effect of the conical diffuser head, the sand particle suspension effect is further enhanced, and the sand-containing liquid can be quickly discharged by opening the sand discharge pipe assembly.
[0021] 3. The design of this sand removal device can effectively solve the problem of sand particle deposition in traditional sand removal, greatly improve the efficiency and effect of sand removal, and ensure the stable operation of the device. Attached Figure Description

[0030] It should be noted that these figures are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0031] Reference Figures 1-3 The present invention discloses a cyclone sand discharge device, comprising: a sand collecting hopper 1, a flange plate 2 connected to the lower end of the sand collecting hopper 1, a flange plate 3 detachably connected to the lower surface of the flange plate 2, a sand discharge pipe assembly 40 connected to the inner hole of the flange plate 3, a cyclone generator 50 provided at the center of the sand collecting hopper 1, the cyclone generator 50 including a fixed pipe body 51 sealed at the upper end, a liquid guiding pipe body 52 passing through the outer circular surface of the fixed pipe body 51, the liquid inlet direction of the liquid guiding pipe body 52 being offset from the axis of the fixed pipe body 51, a central pipe 53 concentrically connected to the top of the inner hole of the fixed pipe body 51, and a conical diffuser head 54 located below the fixed pipe body 51 connected to the lower end of the central pipe 53.
[0032] The sand discharge pipe assembly 40 includes a first sand discharge pipe 41 and a second sand discharge pipe 42. The upper outer circle of the first sand discharge pipe 41 is connected to the inner hole of the second flange plate 3, and the lower end is connected to the sixth flange plate 43. The lower end of the second sand discharge pipe 42 is connected to a switch valve 44, and the upper end is connected to a seventh flange plate 45. The seventh flange plate 45 and the sixth flange plate 43 are connected by bolts. When the switch valve 44 is opened, the sand-containing liquid in the sand collection hopper 1 can flow out sequentially through the first sand discharge pipe 41 and the second sand discharge pipe 42 to achieve the purpose of sand discharge. When the switch valve 44 is closed, the liquid can be prevented from being discharged from the first sand discharge pipe 41 and the second sand discharge pipe 42, thereby achieving an intermittent sand discharge effect.
[0033] A liquid inlet pipe 6 is provided through the circular wall of the sand collection hopper 1. The inner end of the liquid inlet pipe 6 is connected to flange plate 3 7, and the outer end is connected to flange plate 4 8. The end of the liquid guide pipe body 52 away from the fixed pipe body 51 is connected to flange plate 5 9. The flange plate 5 9 and flange plate 3 7 are connected by bolts.
[0034] The lower end of the central tube 53 extends below the fixed tube body 51, and the inner diameter of the fixed tube body 51 is not less than three times the outer diameter of the central tube 53. The extension of the lower end of the central tube 53 to the fixed tube body 51 provides sufficient space for liquid outflow between the conical diffuser head 54 and the fixed tube body 51; at the same time, the inner diameter of the fixed tube body 51 is not less than three times the outer diameter of the central tube 53, ensuring that there is sufficient space between the outer circle of the central tube 53 and the inner wall of the fixed tube body 51, allowing the liquid to form a swirling flow and flow downward.
[0035] The end of the liquid guide tube 52 located inside the fixed tube 51 is flush with the inner wall of the fixed tube 51. The liquid flowing into the liquid guide tube 52 is located between the inner wall of the fixed tube 51 and the outer circle of the central tube 53. The liquid flowing into the liquid guide tube 52 is located between the inner wall of the fixed tube 51 and the outer circle of the central tube 53, so that the flowing liquid can form a stable vortex, thereby driving the sand particles in the sand collecting hopper 1 to be suspended and rotate with the liquid, thus enhancing the sand discharge effect.
[0036] The large diameter of the conical diffuser 54 is not less than the inner diameter of the fixed tube 51. The conical diffuser 54, with its conical surface, can more fully guide the liquid to rotate and disperse in all directions, thereby allowing the sand particles in the sand collection hopper 1 to rotate and suspend fully with the liquid.
[0037] A swirling cavity 11 is provided between the conical diffuser 54 and the flange plate 2. The height of the swirling cavity 11 is not less than the outer diameter of the fixed pipe body 51. Because there is a swirling cavity 11 between the conical diffuser 54 and the flange plate 2, the liquid in the swirling cavity 11 can rotate fully, thereby driving the sand particles at the bottom of the sand collecting hopper 1 to rotate and suspend.
[0038] The implementation principle of this embodiment is as follows: In use, the external high-pressure pipe body is connected to the flange plate 8 of the inlet pipe 6, and the high-pressure liquid flows into the inner cavity of the fixed pipe body 51 through the inlet pipe 6. Because the liquid inlet direction of the guide pipe body 52 deviates from the axis of the fixed pipe body 51, the tangentially entering high-pressure liquid forms a swirling flow in the cavity and flows downward; after the swirling liquid contacts the conical diffuser head 54, it is guided by its conical surface to rotate and disperse in all directions, thereby driving the liquid in the sand collection hopper 1 to rotate synchronously. The swirling effect can suspend the sand particles at the bottom of the sand collection hopper 1 and rotate with the liquid. At this time, the sand discharge pipe assembly 40 can be opened to discharge the sand-containing liquid. This design can effectively avoid sand particle deposition that hinders sand discharge and significantly improve the sand discharge effect.
