Description

Technical Field

[0001] The utility model is applicable to the technical field of chemical equipment and provides a collector for aluminum trichloride. Background Art

[0002] The aluminum chloride production process requires a collector, where aluminum chloride vapor from the chlorination reactor naturally condenses into a solid and forms on the inner wall. Existing collectors typically knock solid aluminum chloride off the inner wall by knocking it off, which not only damages the collector but also creates a lot of noise. Therefore, a rotating scraper has been developed to scrape the solid aluminum chloride off. However, in these collectors, the scraper rotates at high speed against the inner wall. Over time, both the inner wall and the scraper wear out, increasing the gap between them and causing poor scraping performance.

[0003] In order to solve the above problems, it is necessary to develop a new aluminum chloride collector to improve the scraping effect. Utility Model Content

[0004] In view of the above-mentioned defects, the purpose of the present invention is to provide a collector for aluminum trichloride, in order to solve the problems mentioned above.

[0005] A collector for aluminum trichloride comprises a cylinder, wherein the outer wall of the cylinder is sequentially provided with a material inlet, an exhaust gas outlet and a material outlet from top to bottom; a supporting inner cylinder is installed inside the cylinder; a plurality of scrapers are installed on the outer wall of the supporting inner cylinder; a supporting spring is provided between the scrapers and the supporting inner cylinder; the top of the supporting inner cylinder is rotatably connected to the top of the cylinder; the bottom of the supporting inner cylinder is provided with a first shaft; and the bottom of the cylinder is provided with a power mechanism for driving the first shaft to rotate.

[0006] Wherein, a plurality of fixing grooves are provided on the outer wall of the supporting inner cylinder, and the scraper is installed in the fixing grooves.

[0007] Among them, a fixed clamping platform is provided at one end of the fixed groove, and a support platform cooperating with the fixed clamping platform is installed at one end of the scraper. The support platform is located between the fixed clamping platform and the bottom of the fixed groove, and the support spring is located between the support platform and the bottom of the fixed groove.

[0009] Wherein, a second shaft is installed on the top of the supporting inner cylinder, a limiting frame is installed on the outer wall of the cylinder, and the second shaft is rotatably connected to one end of the limiting frame.

[0010] Wherein, the limiting frame includes a limiting platform and a bent arm, one end of the bent arm is fixedly connected to the limiting platform, and the other end of the bent arm is rotatably connected to the second shaft.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Example:

[0024] See also Figure 1-3 The present invention provides a collector for aluminum chloride, comprising a cylinder 1. The outer wall of the cylinder 1 is provided with, from top to bottom, a material inlet 11, an exhaust gas outlet 12, and a material outlet 13. Aluminum chloride vapor enters the cylinder 1 through the material inlet 11, then cools and precipitates within the cylinder 1, condensing on the inner wall of the cylinder 1. The condensed exhaust gas reaches an exhaust gas treatment device through the exhaust gas outlet 12, while the condensed aluminum chloride particles are discharged from the material outlet 13 and collected.

[0025] Since the aluminum chloride particles will adhere to the inner wall of the cylinder 1, in order to force the aluminum chloride particles to separate from the inner wall of the cylinder 1, the traditional method often uses the method of hitting and vibrating, but this method is inefficient. For this reason, this solution adopts the method of scraping with a scraper 21. For this reason, a supporting inner cylinder 2 is installed inside the cylinder 1, and a plurality of scrapers 21 are installed on the outer wall of the supporting inner cylinder 2. A supporting spring 233 is installed between the scraper 21 and the supporting inner cylinder 2. The top of the supporting inner cylinder 2 is rotatably connected to the top of the cylinder 1, and the bottom of the supporting inner cylinder 2 is provided with a first shaft 22. The bottom of the cylinder 1 is provided with a power mechanism that drives the first shaft 22 to rotate. The first shaft 22 is rotatably connected to the bottom of the cylinder 1, and its purpose is to prevent the cylinder 1 from hindering the rotation of the supporting inner cylinder 2. The power mechanism drives the first shaft 22 to rotate, and the first shaft 22 will drive the supporting inner cylinder 2 to rotate during the rotation. At this time, the scraper 21 will rotate together with the supporting inner cylinder 2, so that the aluminum chloride particles on the inner wall of the cylinder 1 are scraped off by the scraper 21, and then gathered at the bottom of the cylinder 1, waiting to be discharged.

[0026] The support spring 233 is used to drive the scraper 21 to cling to the inner wall of the cylinder 1 , so even if one end of the scraper 21 is worn, the scraper 21 can still cling to the inner wall of the cylinder 1 .

[0027] In order to facilitate the fixing of the scraper 21 , a plurality of fixing grooves 23 are provided on the outer wall of the supporting inner cylinder 2 , and the scraper 21 is installed in the fixing grooves 23 .

[0028] To ensure effective scraping, the scraper 21 in this solution needs to be in close contact with the inner wall of the barrel 1. However, this will cause the scraper 21 to wear out too quickly, ultimately affecting the scraping effect. To solve this problem, a fixed clamping platform 231 is provided at one end of the fixed groove 23. A support platform 232 that cooperates with the fixed clamping platform 231 is installed at one end of the scraper 21. The support platform 232 is located between the fixed clamping platform 231 and the bottom of the fixed groove 23. A support spring 233 is provided between the support platform 232 and the bottom of the fixed groove 23.

[0029] The above design allows for a certain amount of margin in the scraper 21. When the end of the scraper 21 wears, the support spring 233 forces the scraper 21 to continue to adhere to the inner wall of the cylinder 1, compensating for the worn portion of the scraper 21 and ensuring that the end of the scraper 21 remains in contact with the inner wall of the cylinder 1. The support platform 232 serves to intercept the scraper 21 and prevent it from falling out of the fixing groove 23.

[0030] In order to facilitate the support of the rotation of the inner cylinder 2, the power mechanism includes a support frame and a power motor 3. The power motor 3 is located on the side of the support frame close to the first shaft 22. The power end of the power motor 3 is installed with a first gear 31, and the side wall of the first shaft 22 is installed with a second gear 32. In order to facilitate the power motor 3 to drive the second gear 32, the first gear 31 is meshed and connected with the second gear 32.

[0031] In order to ensure the smooth rotation of the supporting inner cylinder 2, a second shaft 24 is installed on the top of the supporting inner cylinder 2. A limit frame 14 is installed on the outer wall of the cylinder 1. The second shaft 24 is rotatably connected to one end of the limit frame 14.

[0032] Preferably, the limiting frame 14 includes a limiting platform 141 and a curved arm 142. The limiting platform 141 is located on the outer wall of the cylinder 1. One end of the curved arm 142 is fixedly connected to the limiting platform 141, and the other end of the curved arm 142 is rotatably connected to the second shaft 24. The curved arm 142 is an L-shaped curved arm 142. The purpose of this design is to enable the curved arm 142 to cooperate with the outer wall of the cylinder 1, thereby reducing the volume of the limiting frame 14.

[0033] Aluminum chloride will only condense when it encounters low temperatures. For this reason, the cylinder 1 is provided with an interlayer in which a refrigerant is provided (this mechanism is a mature prior art and will not be described in detail here). However, when aluminum chloride vapor is first introduced, the supporting inner cylinder 2 and the scraper 21 are also low-temperature objects, and aluminum chloride particles will also precipitate on their surfaces. In order to avoid this problem, we need to preheat both. For this reason, the first shaft 22 and the second shaft 24 are both hollow pipes. The first shaft 22 is rotatably connected to the end of the supporting inner cylinder 2 with a medium outlet pipe 42, and the second shaft 24 is rotatably connected to the end of the supporting inner cylinder 2 with a medium inlet pipe 41. The medium outlet pipe 42 and the medium inlet pipe 41 are both connected to the medium heating device 4. The supporting inner cylinder 2 in this solution is provided with an inner cavity, and the medium heating device 4 sends the hot medium to the second shaft 24 through the medium inlet pipe 41. Subsequently, the hot medium reaches the inner cavity of the supporting inner cylinder 2, the first shaft 22, the medium outlet pipe 42 in sequence, and finally returns to the medium heating device 4. The support inner cylinder 2 in this solution is in thermal contact with the scraper 21. This design allows the temperature of the support inner cylinder 2 to be freely transferred to the scraper 21. At this time, when the scraper 21 and the support inner cylinder 2 reach a certain temperature, aluminum chloride vapor is introduced into the inner cylinder.

[0034] In order to facilitate observation of the scraping situation, an upper manhole 15 and a lower manhole 16 are further installed on the side wall of the cylinder 1 , and the upper manhole 15 and the lower manhole 16 are located between the material inlet 11 and the material outlet 13 .

[0035] In summary, the advantages of this solution are as follows: First, the support spring 233 allows the scraper 21 to be retractable, allowing the end of the scraper 21 to fit closely against the inner wall of the cylinder 1, maximizing the scraping effect. Second, the first shaft 22, the second shaft 24, and the supporting inner cylinder 2 in this solution are hollow. When a heat medium is passed through them, the supporting inner cylinder 2 and the scraper 21 are heated, and aluminum chloride is precipitated only on the inner wall of the cylinder 1, thereby preventing aluminum chloride particles from adhering to the outer wall of the supporting inner cylinder 2.

[0036] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
