Technical Field

[0001] The utility model relates to the technical field of water blocking for crystallizers, and specifically relates to a water blocking structure for a crystallizer. Background Technique

[0002] A cooling crystallizer is a device that relies on reducing the temperature of materials to cause supersaturation of the materials and ultimately promotes the crystallization of the materials; in the prior art, the commonly used water blocking structure for the traditional crystallizer cooling method is to set grooves on the outer wall of the copper tube and set an external water jacket outside the copper tube, in order to limit the cooling water to flow only from the grooves.

[0003] During the use of the existing crystallizer, due to the large amount and fast flow rate of the cooling water flowing through the grooves in the copper tube, the cooling water cannot effectively absorb the heat of the crystallizer copper tube after passing through the crystallizer copper tube, thereby reducing the heat transfer efficiency of the crystallizer copper tube and the cooling effect of the crystallizer copper tube. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water blocking structure for a crystallizer, so as to solve the problem that during the use of the existing crystallizer, due to the large amount and fast flow rate of the cooling water flowing through the grooves in the copper tube, the cooling water cannot effectively absorb the heat of the crystallizer copper tube after passing through the crystallizer copper tube, thereby reducing the heat transfer efficiency of the crystallizer copper tube and the cooling effect of the crystallizer copper tube as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A water blocking structure for a crystallizer, including a crystallizer copper tube;

[0006] An annular heat conducting sheet is installed on the outer wall of the crystallizer copper tube, a heat conducting tube is connected to the outer wall of the annular heat conducting sheet, both ends of the heat conducting tube are commonly connected to a box, and a water treatment component is arranged inside the box;

[0007] A plurality of side rods are rotatably connected to the inner wall of the heat conducting tube at equal intervals, and three blades are circumferentially and equidistantly connected to the side wall of each side rod.

[0008] Preferably, the water treatment component includes a water cooling block and a water pump;

[0009] The water cooling block is installed on the inner wall of the box, one end of the water cooling block is connected to any port of the heat conducting tube in a communicating manner, the water pump is installed on the inner wall of the box, and the port of the water pump is connected to the other port of the heat conducting tube in a communicating manner.

[0010] Preferably, a plurality of connecting rods are connected to the outer wall of the annular heat conducting sheet, and each connecting rod is commonly connected to the outer wall of the box.

[0011] Preferably, a plurality of conical holes are formed inside each of the blades.

[0012] Preferably, a bevel edge is formed on the outer wall of each of the blades.

[0013] Preferably, a plurality of heat dissipation fins are connected to the outer wall of the annular heat conducting sheet, and each heat dissipation fin is connected to the outer wall of the heat conducting tube.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By providing the side rod and the blades, during the flow of water inside the heat conducting tube, the water flow will continuously impact the blades, causing the blades to drive the side rod to rotate inside the heat conducting tube, slowing down the water flow velocity, thereby achieving a water blocking effect. The rotation of the blades generates a certain stirring effect, which helps to break the temperature stratification in the water flow, making the temperature distribution in the water flow more uniform. At the same time, the stirring effect can also promote the convective heat transfer between the water flow and the heat conducting tube, further improving the cooling efficiency. By extending the contact time of the water flow inside the heat conducting tube with the crystallizer copper tube, the heat of the crystallizer copper tube can be effectively absorbed, thereby improving the heat transfer efficiency and cooling effect of the crystallizer copper tube;

[0016] 2. When the water flow impacts the conical holes, the cross-sectional area of the water flow will be reduced, thereby increasing the local resistance when the water flow passes through. This resistance will slow down the overall velocity of the water flow. When the water flow impacts the bevel edge, the direction will change and energy will be dissipated, slowing down the water flow velocity. By slowing down the flow velocity of the water flow inside the heat conducting tube, the heat exchange time between the water flow and the heat conducting tube is increased, which helps to more effectively transfer the heat of the crystallizer copper tube to the water flow.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-5 , the present invention provides a technical solution: a water-blocking structure of a mould, including a mould copper tube 1;

[0025] An annular heat-conducting fin 2 is installed on the outer wall of the mould copper tube 1, a heat-conducting tube 3 is connected to the outer wall of the annular heat-conducting fin 2, both ends of the heat-conducting tube 3 are jointly connected to a box 4, and a water treatment component is arranged inside the box 4;

[0026] A plurality of side rods 8 are rotatably connected to the inner wall of the heat-conducting tube 3 at equal intervals, and three blades 9 are circumferentially and equidistantly connected to the side wall of each side rod 8; by arranging a plurality of side rods 8 and blades 9, the water flow will continuously impact the blades 9 during the flow through the heat-conducting tube 3, causing the blades 9 to drive the side rods 8 to rotate inside the heat-conducting tube 3, slowing down the water flow speed, thereby achieving a water-blocking effect. The flow rate slows down, and the residence time of the water flow in the heat-conducting tube 3 increases, which helps to exchange heat with the wall surface of the annular heat-conducting fin 2, improving the cooling effect to a certain extent. The rotation of the blades 9 generates a certain stirring effect, which helps to break the temperature stratification in the water flow, making the temperature distribution in the water flow more uniform. At the same time, the stirring effect can also promote the convective heat transfer between the water flow and the heat-conducting tube 3, further improving the cooling efficiency.

[0027] The water treatment component includes a water-cooling block 6 and a water pump 7;

[0028] The water-cooling block 6 is installed on the inner wall of the box 4, one end of the water-cooling block 6 is connected to any port of the heat-conducting tube 3 in a communicating manner, the water pump 7 is installed on the inner wall of the box 4, and the port of the water pump 7 is connected to the other port of the heat-conducting tube 3 in a communicating manner; the water flowing through the heat-conducting tube 3 is cooled and refluxed through the water treatment component.

[0029] A plurality of connecting rods 5 are connected to the outer wall of the annular heat-conducting fin 2, and each connecting rod 5 is jointly connected to the outer wall of the box 4.

[0030] Each blade 9 is internally provided with a plurality of tapered holes 10; by providing the tapered holes 10, the cross-sectional area of the water flow is reduced, thereby increasing the local resistance when the water flow passes through, and this resistance will slow down the overall speed of the water flow.

[0031] The outer wall of each blade 9 is provided with a bevel 11; by providing the bevel 11, when the water flow impacts the bevel 11, the direction will change and energy will be dissipated, which will slow down the speed of the water flow. By slowing down the flow rate of the water flow inside the heat conduction tube 3, the heat exchange time between the water flow and the heat conduction tube 3 is increased, which helps to more effectively transfer the heat of the crystallizer copper tube 1 to the water flow.

[0032] A plurality of heat dissipation fins 12 are connected to the outer wall of the annular heat conduction sheet 2, and each heat dissipation fin 12 is connected to the outer wall of the heat conduction tube 3; by providing the heat dissipation fins 12, it can play a role in conducting the heat of the annular heat conduction sheet 2 and the heat conduction tube 3, and at the same time can play a certain protective role on the outer wall of the heat conduction tube 3, reducing the phenomenon of damage to the outer wall of the heat conduction tube 3.

[0033] Working principle: First, the water cooled by the water cooling block 6 inside the box 4 is pumped into the heat conduction tube 3 by the water pump 7. Under the traction of gravity, the water flow descends along the spiral trajectory inside the heat conduction tube 3. During the flow of the water flow, it will continuously impact the blade 9, causing the blade 9 to drive the side rod 8 to rotate inside the heat conduction tube 3, slowing down the water flow speed, thereby achieving a water blocking effect. With the flow rate slowing down, the residence time of the water flow inside the heat conduction tube 3 increases, which helps to exchange heat with the wall surface of the annular heat conduction sheet 2, improving the cooling effect to a certain extent. The rotation of the disc generates a certain stirring effect, which helps to break the temperature stratification in the water flow, making the temperature distribution in the water flow more uniform. At the same time, the stirring effect can also promote the convective heat transfer between the water flow and the pipe wall, further improving the cooling efficiency. By providing the tapered holes 10, the through holes will reduce the cross-sectional area of the water flow, thereby increasing the local resistance when the water flow passes through, and this resistance will slow down the overall speed of the water flow. By providing the bevel 11, when the water flow impacts the bevel 11, the direction will change and energy will be dissipated, which will slow down the speed of the water flow. By slowing down the flow rate of the water flow inside the heat conduction tube 3, the heat exchange time between the water flow and the heat conduction tube 3 is increased, which helps to more effectively transfer the heat of the crystallizer copper tube 1 to the water flow. Until the water flow returns to the inside of the box 4 through the water cooling block 6, by providing the heat dissipation fins 12, it can play a role in conducting the heat of the annular heat conduction sheet 2 and the heat conduction tube 3, and at the same time can play a certain protective role on the outer wall of the heat conduction tube 3, reducing the phenomenon of damage to the outer wall of the heat conduction tube 3.
