[0001] The utility model relates to the technical field of cyclone separation, in particular to a ballast water cyclone separator. Background Art

[0002] With the rapid development of the global shipping industry, the problem of ballast water generated by ships during navigation has become increasingly prominent. If a large amount of suspended matter and harmful substances in the ballast water are discharged into the ocean, it will have a serious impact on the marine ecological environment:

[0003] Although traditional ballast water treatment methods can remove suspended solids in ballast water to a certain extent, there are problems with unstable treatment effects. For example, the separated water flow still contains fine impurity particles and the swirl angle and flow rate cannot be adjusted according to different ballast water conditions. Utility Model Content

[0004] In order to solve the problem that the water flow after cyclone separation still carries fine impurity particles and the cyclone flow rate cannot be changed, resulting in poor separation effect; the purpose of the utility model is to provide a ballast water cyclone separator.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a ballast water cyclone separator, comprising a cyclone separator body, a water outlet pipe fixedly provided at the top end of the cyclone separator body, a filter barrel fixedly connected to one end of the water outlet pipe away from the cyclone separator body, a filter screen movably installed inside the filter barrel, the outer surface of the filter screen is in contact with the inner wall of the filter barrel, a bottom cover movably installed on the lower surface of the filter barrel, a bottom support fixedly installed on the top end of the bottom cover, a first slide groove provided on the upper surface of the bottom support along the lower surface of the filter screen, and the filter screen can be slidably clamped on the top end of the bottom support.

[0006] Preferably, in the ballast water cyclone separator as described in the claim, a fixing cylinder is fixedly provided on the outer surface of the filter barrel close to the side of the bottom cover, a pull rod is slidably provided on the top end of the fixing cylinder away from the side of the filter barrel, a spring is movably installed on the outer surface of the pull rod, the outer surface of the spring is in contact with the inner wall of the fixing cylinder, one end of the pull rod is fixedly connected to a limiting block close to the inner wall of the filter barrel, the side wall of the limiting block is in contact with the other end of the spring, and the upper surface of the limiting block is in contact with the lower surface of the bottom support.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] 1. By utilizing the filter screen inside the filter barrel, the fluid that still contains tiny impurity particles after purification can be additionally filtered, overcoming the problem that may exist in the separation process of the cyclone separator, that is, some tiny impurity particles that should be discharged may enter the outlet pipe, ensuring that the discharged ballast water is purer;

[0009] 2. The staff changes the diameter of the fluid passing through by operating the synchronous variable diameter structure, thereby adjusting the flow rate and angle of the swirl. That is, according to different ballast water conditions, the appropriate diameter and flow rate can be selected for impurity particles of different particle sizes to achieve the best separation effect and improve separation efficiency.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] Example: Figure 1-3As shown, the utility model provides a ballast water cyclone separator, including a cyclone separator body 1, a water outlet pipe 3 is fixedly provided at the top of the cyclone separator body 1, and a filter barrel 301 is fixedly connected to the end of the water outlet pipe 3 away from the cyclone separator body 1, and a filter screen 302 is movably installed inside the filter barrel 301, and the outer surface of the filter screen 302 is in contact with the inner wall of the filter barrel 301, and a bottom cover 303 is movably installed on the lower surface of the filter barrel 301, and a bottom support 310 is fixedly installed on the top of the bottom cover 303, and a first slide groove 304 is provided on the upper surface of the bottom support 310 along the lower surface of the filter screen 302, and the filter screen 302 can be slidably clamped on the top of the bottom support 310; the cylindrical filter screen 302 can better and more widely intercept impurities, thereby improving the filtering effect.

[0017] When the bottle cap 302 is in the closed position, the bottle cap 302 is in the closed position, and the bottle cap 302 is in the closed position, so that the bottle cap 302 can be easily removed.

[0018] The outer surface of the pull rod 306 is rotatably connected to a pull ring 309 on the side away from the filter barrel 301. The pull rod 306 can be easily pulled through the pull ring 309, so that the limit block 305 can be moved, making it easier for the staff to work.

[0019] A water inlet pipe 2 is fixed to the side wall of the cyclone separator body 1. The water inlet pipe 2 is used to facilitate the injection of the liquid to be separated. A rotating disk 21 is rotatably installed inside the water inlet pipe 2, and an adjusting component is installed on the rotating disk 21; a rotating hole 23 is opened through the outer surface of the rotating disk 21, and a fixed disk 24 is provided on the outer surface of the rotating disk 21 close to the side of the cyclone separator body 1. The outer wall of the fixed disk 24 is fixed on the inner ring of the water inlet pipe 2, and a triangular plate 27 is slidably installed on the outer surface of the fixed disk 24 close to the side of the rotating disk 21. A second slide groove 25 is opened on the outer surface of the fixed disk 24 along the edge of the triangular plate 27, and a slider 26 is installed on the side wall of the triangular plate 27 that is slidably arranged in the second slide groove 25. A fixing column 2 is fixedly installed on the upper surface of the triangular plate 27 close to the side of the fixed disk 24. 8. The fixed column 28 can be slidably clamped in the rotating hole 23. By rotating the rotating disk 21, the fixed column 28 is driven to move to the other end of the rotating hole 23. At the same time, the six triangular plates 27 connected to the fixed column 28 will be synchronously rotated and offset to the other direction when the slider 26 cooperates with the second slide groove 25, thereby changing the diameter of the fluid channel, changing the flow rate and flow characteristics of the fluid, optimizing the angle and speed of the vortex formation, and enhancing the separation effect; a rotating handle 22 is fixedly installed on the outer surface of the rotating disk 21, and a third sliding groove 29 is opened on the outer surface of the water inlet pipe 2 near the rotating handle 22. By rotating the rotating handle 22 along the third sliding groove 29, the rotating disk 21 can be rotated, which is convenient for the operator to change the diameter of the fluid passing through.

[0020] A bottom support frame 11 is fixedly connected to the middle of the outer surface of the cyclone separator body 1. The evenly distributed bottom support frames 11 can effectively disperse the weight of the equipment, improve the overall stability, and ensure efficient and smooth operation.

[0021] Working principle: First, when the suspension composed of solid particles and liquid enters the water inlet pipe 2, it will enter the cyclone separator body 1 in a tangential direction and then begin to rotate, forming an external vortex. As the suspension rotates in the cyclone separator body 1, centrifugal force acts on the solid particles therein. Since the density of the particles is greater than that of the liquid, they will be subjected to a greater centrifugal force and move toward the inner wall of the cyclone separator body 1. After the particles reach the inner wall, due to the design of the cyclone separator body 1, the particles will move downward along the wall and gather near the bottom outlet of the cyclone separator body 1, and finally be discharged through the bottom outlet;

[0022] After the filter screen 302 is removed, the filter sieve 301 is cleaned and replaced, and the impurities on the inner wall of the filter barrel 301 are cleaned. After cleaning, it is put back into place, and the limit block 305 fixes the filter screen 302 and the bottom support 310 under the action of the spring 307, so that it will not move downward.

[0023] Inside the water inlet pipe 2, the suspension will pass through the rotating disk 21 and the fixed disk 24. By turning the rotating handle 22, the rotating disk 21 will be driven to rotate. At this time, since the fixed column 28 is stuck in the rotating hole 23, the fixed column 28 will be driven to move to the other end of the rotating hole 23. At the same time, the six triangular plates 27 connected to the fixed column 28 will be synchronously rotated and offset to the other direction when the slider 26 cooperates with the second chute 25, thereby changing the diameter of the fluid passing through, changing the flow rate and flow characteristics of the fluid, optimizing the angle and speed of the vortex formation, enhancing the separation effect, and allowing the operator to adjust the vortex chamber according to different ballast water conditions to improve the separation efficiency.

[0024] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
