Description

Technical Field

[0001] The utility model relates to a spiral flow channel, in particular to a spiral flow channel for a cooling crystallization device applied to the field of cooling crystallization equipment. Background Art

[0002] Black titanium liquid is an important chemical raw material, which is widely used in fields such as titanium dioxide, titanium alloy, and titanate. It belongs to a special solution with special properties. For example, it may hydrolyze when diluted or heated for a long time. And to avoid hydrolysis, its concentration must be carried out by low-temperature evaporation under vacuum. During the use and production process of black titanium liquid, a cooling crystallization device is needed to cool it down.

[0003] In the cooling crystallization device, the spiral flow channel is an important component. During the use of the existing spiral flow channel, multiple straight pipes in the tube-side component are inserted into the through-holes of the spiral plate, and then the coolant is pumped into the spiral plate. The black titanium liquid in the straight pipes is cooled by the impact flow of the water. However, the existing spiral flow channel has no fixing components, and the flow impact of the coolant will cause vibration to the spiral flow channel. After long-term use, the spiral flow channel may drop, or even fall off from the crystallization tank, thus shortening the service life of the spiral flow channel. Summary of the Utility Model

[0004] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that after inserting multiple straight pipes of the tube-side component into the through-holes of the spiral plate, the long-term flow impact of the coolant on the straight pipes will cause vibration to the spiral flow channel. After long-term use, the spiral flow channel may drop, or even fall off from the crystallization tank, thus shortening the service life of the spiral flow channel.

[0005] To solve the above problems, the utility model provides a spiral flow channel for a cooling crystallization device, which includes a spiral plate arranged between the tank body and the inner cylinder of the crystallization tank. Fixed plates are fixedly sleeved on the upper and lower ends of the outer surface of the inner cylinder. The spiral plate is located between the two fixed plates. Through-holes are drilled on the surfaces of the fixed plates and the spiral plate. The upper end of the spiral plate is also fixedly connected with a first positioning strip and a second positioning strip. The outer side of the first positioning strip is fixedly connected with the inner wall of the tank body of the crystallization tank, and the inner side of the second positioning strip is fixedly connected with the outer surface of the inner cylinder. A plurality of inserting plates are fixedly connected to the outer surface of the fixed plate. The end of the inserting plate away from the inner cylinder fixedly penetrates through the tank body of the crystallization tank. A plurality of support rods are fixedly connected to the upper end of the lower fixed plate. The upper end of the support rod is fixedly connected with the spiral plate. Two fixing rods are arranged above the upper fixed plate. The lower end of the fixing rod sequentially passes through the fixed plate, the spiral plate and the other fixed plate movably, and nuts are threadedly sleeved on both ends of the outer surface of the fixing rod. A water inlet pipe and a water outlet pipe are fixedly connected to the outer surface of the tank body of the crystallization tank. The water inlet pipe is located below the water outlet pipe.

[0006] In the spiral flow channel for the above cooling crystallization equipment, the spiral plate is supported and fixed to improve the stability of the spiral plate, thereby avoiding the phenomenon of the spiral plate falling off after long-term use, and further extending the service life of the spiral plate.

[0007] As a further improvement of the present application, both the positioning strip one and the positioning strip two are spiral, and the positioning strip one and the positioning strip two do not contact the through holes, and the corresponding ends of the positioning strip one and the positioning strip two are both rounded.

[0008] As a further further improvement of the present application, multiple through holes, multiple insertion plates, and multiple support rods are all distributed in a circular array around the central axis of the inner cylinder, and the support rods are made of elastic materials.

[0009] As another improvement of the present application, a filter screen is fixedly connected inside the water pipe, an installation rod rotates through the left end of the filter screen, a scraping plate is fixedly connected to the outer surface of the installation rod, an impeller is fixedly connected to the end of the installation rod away from the filter screen, a discharge pipe is fixedly connected to the outer surface of the water inlet pipe, and a one-way electric valve is fixedly installed on the outer surface of the discharge pipe.

[0010] As a supplement to another improvement of the present application, the end of the scraping plate close to the filter screen is in a triangular pyramid shape, and the end of the scraping plate close to the filter screen contacts the filter screen.

[0011] As a supplement to another improvement of the present application, the one-way electric valve is signal-connected to an external controller, and the discharge pipe is located between the filter screen and the impeller.

[0012] In summary, in the actual application process, multiple straight pipes of the tube-side component are inserted into the through holes, the coolant enters the crystallization tank body through the water inlet pipe, and through the partition of the spiral plate and the inner cylinder, the coolant flows from bottom to top. During the flowing process, the straight pipes will be continuously impacted, thereby cooling the black titanium liquid in the straight pipes. The fixing plate and the crystallization tank body are fixed by multiple insertion plates, and then the spiral plate and the fixing plate are fixed by the fixing rod and the nut. The contact area between the spiral plate, the crystallization tank body and the inner cylinder is increased by the positioning strip one and the positioning strip two. The support rod can absorb the vibration generated by the spiral plate and improve the stability of the spiral plate during use, thereby avoiding the phenomenon of the spiral plate falling off after long-term use, and further extending the service life of the spiral plate.

Specific embodiments

[0022] The following will make a detailed description of the two embodiments of the present application with reference to the accompanying drawings.

[0023] The first embodiment:

[0024] Figure 1 and Figure 2 show: A spiral flow channel for a cooling crystallization device, including a spiral plate 3 arranged between the crystallization tank body 1 and the inner cylinder 2. Fixing plates 4 are fixedly sleeved on both the upper and lower ends of the outer surface of the inner cylinder 2. The spiral plate 3 is located between the two fixing plates 4. A plurality of through holes 5 are drilled on the surfaces of the fixing plate 4 and the spiral plate 3. The outer surface of the crystallization tank body 1 is fixedly connected with a water inlet pipe 12 and a water outlet pipe 13. The water inlet pipe 12 is located below the water outlet pipe 13, so that the coolant enters from the bottom and exits from the top, improving the cooling effect. A plurality of support rods 9 are fixedly connected to the upper end of the lower fixing plate 4. The upper end of the support rod 9 is fixedly connected with the spiral plate 3. The support rod 9 is made of an elastic material. The elastic support rod 9 can absorb the jitter generated during the use of the spiral plate 3, thereby reducing the vibration of the spiral plate 3.

[0025] Figure 3 、 Figure 4 and Figure 5It is shown that: a first positioning strip 6 and a second positioning strip 7 are also fixedly connected to the upper end of the spiral plate 3. The outer side of the first positioning strip 6 is fixedly connected to the inner wall of the crystallization tank body 1, and the inner side of the second positioning strip 7 is fixedly connected to the outer surface of the inner cylinder 2. Both the first positioning strip 6 and the second positioning strip 7 are spiral-shaped, and neither the first positioning strip 6 nor the second positioning strip 7 is in contact with the through holes 5. The corresponding ends of the first positioning strip 6 and the second positioning strip 7 are both rounded. The rounded first positioning strip 6 and second positioning strip 7 can effectively reduce resistance, increase the contact area between the spiral plate 3 and the crystallization tank body 1 and the inner cylinder 2, and effectively improve the stability of the spiral plate 3. A plurality of insertion plates 8 are fixedly connected to the outer surface of the fixing plate 4. One end of the insertion plate 8 away from the inner cylinder 2 fixedly penetrates through the crystallization tank body 1. There are two fixing rods 10 above the upper fixing plate 4. The lower ends of the fixing rods 10 sequentially pass through the fixing plate 4, the spiral plate 3 and another fixing plate 4 movably, and nuts 11 are threadedly sleeved on both ends of the outer surface of the fixing rod 10, so as to fix the fixing plate 4 and the spiral plate 3. The plurality of through holes 5, the plurality of insertion plates 8 and the plurality of support rods 9 are all arranged in a circular array around the central axis of the inner cylinder 2.

[0026] During use, a plurality of straight pipes of the tube-side component are inserted into the through holes 5. The coolant enters the crystallization tank body 1 through the water inlet pipe 12. Through the partition of the spiral plate 3 and the inner cylinder 2, the coolant flows from bottom to top. During the flowing process, it will continuously impact the straight pipes, thereby cooling the black titanium liquid in the straight pipes. The fixing plate 4 and the crystallization tank body 1 are fixed through the plurality of insertion plates 8, and then the spiral plate 3 and the fixing plate 4 are fixed through the fixing rods 10 and the nuts 11. The contact area among the spiral plate 3, the crystallization tank body 1 and the inner cylinder 2 is increased through the first positioning strip 6 and the second positioning strip 7. The support rod 9 can absorb the vibration generated by the spiral plate 3 and improve the stability of the spiral plate 3 during use, thereby preventing the spiral plate 3 from falling off after long-term use, and further extending the service life of the spiral plate 3.

[0027] The second embodiment:

[0028] On the basis of the first embodiment, a filter screen 14, a mounting rod 15, a scraper 16, an impeller 17 and a discharge pipe 18 are newly added, and the rest is the same as the first embodiment.

[0029] Figure 6 and Figure 7It is shown that a filter screen 14 is fixedly connected inside the water inlet pipe 12. The filter screen 14 can filter the coolant, effectively preventing the impurity particles in the coolant from accumulating at the bending part of the spiral plate 3 and extending the service life of the spiral plate 3. A mounting rod 15 rotatably penetrates through the left end of the filter screen 14. A scraping plate 16 is fixedly connected to the outer surface of the mounting rod 15. An impeller 17 is fixedly connected to the end of the mounting rod 15 far away from the filter screen 14. The impact of the water flow on the impeller 17 can drive the mounting rod 15 to rotate, so that the scraping plate 16 scrapes the filter screen 14, effectively preventing the filter screen 14 from being blocked. A discharge pipe 18 is fixedly connected to the outer surface of the water inlet pipe 12. A one-way electric valve is fixedly installed on the outer surface of the discharge pipe 18. One end of the scraping plate 16 close to the filter screen 14 is in a triangular pyramid shape, and one end of the scraping plate 16 close to the filter screen 14 is in contact with the filter screen 14. The discharge pipe 18 can store the impurity particles in the coolant. After the spiral plate 3 is used up, the one-way electric valve can be started to discharge the impurity particles. The one-way electric valve is signal-connected to an external controller. Those skilled in the art can select a suitable model of the one-way electric valve according to actual needs. For example: D341X-10C. The discharge pipe 18 is located between the filter screen 14 and the impeller 17.

[0030] During use, the coolant passes through the filter screen 14 for filtration, thus effectively preventing impurity particles from entering the inside of the spiral plate 3 and causing scaling at the bending part inside the spiral plate 3, thereby extending the service life of the spiral plate 3. When the coolant enters the water inlet pipe 12, it impacts the impeller 17, driving the impeller 17 to rotate. The mounting rod 15 rotates accordingly, so that the scraping plate 16 scrapes the surface of the filter screen 14, effectively preventing the surface of the filter screen 14 from being blocked.

[0031] Combined with the current actual needs, the above-mentioned implementation manner adopted in this application, the scope of protection is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
