[0061] This utility model will primarily focus on applications in the marine field.

[0062] like Figure 1-6 As shown, this embodiment provides a cyclone separator 100 for purifying seawater impurities, including an outer cylinder 20 and an inner cylinder disposed within the outer cylinder 20; further, the outer cylinder 20 and the inner cylinder are connected by welding or fastening screws or other fixed connections, and the distance L5 between the outer cylinder 20 and the inner cylinder is 4.5mm;

[0063] The outer cylinder 20 includes two sets of first and second outer cylinders, and the two sets of first and second outer cylinders are connected by a mounting plate 30. In actual application, the first and second outer cylinders are cast separately, and then the first and second outer cylinders are welded to the mounting plate 30 respectively, thereby realizing the assembly of the outer cylinder.

[0064] Furthermore, the outer cylinder 20 is provided with an inlet end 10 integrally formed therewith;

[0065] An overflow pipe 60 is provided on the top end face of the outer cylinder 20.

[0066] Furthermore, a splash guard 50 is provided on the outer cylinder 20, which is away from the overflow pipe 60.

[0067] Furthermore, a vortex body is provided inside the inner cylinder, and the vortex body is arranged in a spiral shape. In practical applications, when seawater containing impurities is transported into the inner cylinder through the inlet end 10, the seawater containing impurities moves tangentially along the vortex body inside the inner cylinder, thereby causing the seawater containing impurities to rotate along the inner wall of the inner cylinder. At this time, the impurities are subjected to centrifugal force. When the density is greater than the density of the surrounding liquid, the centrifugal force becomes larger and larger. When the centrifugal force is greater than the liquid resistance generated by the movement, the impurities contained in the seawater will overcome this resistance and move towards the splash guard 50, separating from the surrounding seawater, so that the impurities are discharged through the drain pipe 501.

[0068] Furthermore, a groove 101 is formed on the inner wall of the inlet end 10, and the groove 101 has a depth of 21 mm. A conveying pipe 201 is arranged in the groove 101, such that the outer wall of the conveying pipe 201 is in close contact with the inner wall of the groove 101, and the other end of the conveying pipe 201 extends into the upper chamber 204 of the inner cylinder.

[0069] When the insertion depth is 0.5mm, vortex generation can be effectively prevented, achieving high separation efficiency while maintaining low energy consumption.

[0070] Furthermore, the conveying pipe 201 has a diameter of 20mm, and the shape of the conveying pipe corresponds to that of the inlet end, making it as a whole curved shape to avoid abrupt right angle changes and reduce eddy current intensity. The inlet end of the conveying pipe is inclined at 45°-60° to guide the fluid smoothly into the flow channel and reduce flow separation.

[0071] Furthermore, the inner cylinder includes an upper chamber 204 and a lower chamber 205 connected by welding, and a drain pipe 501 connected to the lower chamber 205 is provided therewith.

[0072] The upper chamber 204 is cylindrical, and the lower chamber 205 is conical, with its diameter decreasing towards the drain pipe 501.

[0073] The diameter L9 of the bottom end face of the lower chamber 205 near the sewage pipe is 14.5 mm, and the height L8 between the bottom end face of the lower chamber 205 and the bottom end face of the sewage pipe 501 is 33 mm, and the height L7 of the lower chamber is 265 mm.

[0074] Furthermore, the height L4 of the upper chamber 204 is 105mm, and the inner diameter L6 of the upper chamber 204 is 108mm.

[0075] Furthermore, the inner wall of the overflow pipe 60 is provided with an installation hole 206, and an overflow conduit 207 is provided in the installation hole 206. The overflow conduit 207 and the installation hole 206 can be fixedly connected by welding or other means. The overflow conduit 207 extends out of the installation hole 206, extends into the flow channel 202 of the inner cylinder, and communicates with the inner pipe 203.

[0076] Furthermore, the overflow conduit 207 and the inner tube 203 are integrally formed and are arranged in a stepped shape. The overflow pipe 60 has a diameter of 45 mm and a height of 19 mm.

[0077] Furthermore, the flow channel 202 is located within the upper chamber 204, and the height L3 of the flow channel 202 is 50mm, and the diameter of the flow channel 202 is 32mm.

[0078] This utility model has a simple overall structure and small size. It can achieve solid-liquid separation, remove a certain proportion of mud and sand from seawater, and protect the centrifugal pump for normal operation.

[0079] In this embodiment, those skilled in the art should understand that, firstly, the operator determines the performance indicators and, based on the pump's operating environment, simulates the actual operating environment by setting parameters, specifically:

[0080] Initially, silica sand No. 8 was selected as the experimental sand to simulate impurities in seawater. The particle diameter was 0.05-0.2 mm, the specific gravity was about 2.6, and the concentration was set at 0.6% (6 kg of silica sand was added to 1000 L of water).

[0081] Confirm the design parameters and perform theoretical calculations, such as:

[0082] Initially, determine the technical parameters such as liquid flow rate, separation efficiency, pressure drop limit, materials, and environment.

[0083] Using fluid mechanics knowledge and Ansys simulation software, the preliminary design (the dimensions of the cyclone separator, such as diameter, height, inlet and outlet dimensions, etc.) is simulated and calculated. By simulating the boundary of the cyclone separator, a flow channel diagram is created using 3D software, dimensional variables are set, and the simulation is performed by importing the data into Fluet 3D simulation software.

[0084] According to the simulation results, such as his 4 and Figure 5 As shown, the pressure drop has a positive correlation with the separation efficiency, exhibiting a "camel hump" effect, meaning that both the pressure drop and separation efficiency of the cyclone separator show a trend of first increasing and then decreasing.

[0085] Therefore, when the diameter of the conveying pipe 201 is 20mm and the whole is curved, the inclination of the inlet end of the conveying pipe is set to 45°-60°, and the insertion depth is 0.5mm, and the overflow conduit 207 is provided in the mounting hole 206, the overflow conduit 207 and the mounting hole 206 can be fixedly connected by welding or other means. The overflow conduit 207 extends out of the mounting hole 206, extends into the flow channel 202 of the inner cylinder, and connects to the inner pipe 203. The overflow conduit 207 and the inner pipe 203 are integrated and the whole is stepped. The diameter of the overflow pipe 60 is 45mm and the height of the overflow pipe 60 is 19mm. High separation efficiency is achieved while maintaining low energy consumption, so that the formation of eddies can be minimized, the efficiency can be improved, and the sediment in the seawater can be separated. The water quality after separation can meet the operating requirements of the centrifugal pump, and the equipment can be effectively protected from sediment wear.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
