Description

Technical Field

[0001] The utility model belongs to the technical field related to continuous crystallization, in particular to a vertical continuous crystallizer. Background Art

[0002] Vertical crystallizers are mainly used to separate crystals from solutions. Their principle is based on the physical and chemical laws of solubility and crystallization process. During the crystallization process, the solubility and temperature of the solute in the solvent and the design of the crystallizer are controlled to achieve the process of solute condensation from solution into crystals. This equipment can significantly improve the purity and stability of the substance.

[0003] Common vertical crystallizers put raw materials into the reactor for concentration, cooling, stirring and filtering to produce crystals. The raw materials in the reactor need to be processed before the next operation, which increases the time and cost of crystallization and wastes raw materials because some solutes are not completely precipitated. To this end, we provide a vertical continuous crystallizer to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0026] See also Figure 1-6 The utility model is a vertical continuous crystallizer, comprising a crystallization cylinder 1, a plurality of partition components 2 and a plurality of stirring components 3. Specifically, the partition component 2 is fixedly connected to the inside of the crystallization cylinder 1, and the partition component 2 divides the crystallization cylinder 1 into a plurality of crystallization chambers. The solution enters the crystallization chamber and is concentrated, stirred, cooled and crystallized to precipitate crystals. Each crystallization chamber is connected to an opening and closing door on the side surface for easy removal of the precipitated crystals. The partition component 2 comprises a filter port 201, a horizontally movable opening and closing baffle 202 and an adjusting connecting rod 203 symmetrically arranged for rotation. A filter plate is fixedly connected to the inside of the filter port 201 to separate the solution from the crystals, and the size of the filter plate is consistent with the size of the opening and closing baffle 202. The opening and closing baffle 202 is adapted to the filter port 201. When the opening and closing baffle 202 moves to the inside of the filter port 201, it is blocked, thereby realizing the switch control of the filter port 201.

[0027] Furthermore, the stirring component 3 is fixedly installed inside the corresponding crystallization chamber, and the stirring component 3 includes a plurality of sliding adjustment transmission blocks 301, and the lower surface of the adjustment transmission block 301 is fixedly connected with a stirring scraper 302. The horizontal movement of the adjustment transmission block 301 drives the stirring scraper 302 to move synchronously to stir the solution. When the stirring scraper 302 is in contact with the inner wall of the crystallization chamber, the attached crystals are scraped off.

[0028] The operation process of this embodiment is as follows: control the opening and closing baffle 202 to move horizontally. When the opening and closing baffle 202 is located directly below the filter port 201, the adjusting connecting rod 203 is hindered from rotating, driving the opening and closing baffle 202 to move upward and slide along the filter port 201 until the filter port 201 is closed. After the solution enters the crystallization chamber, the driving block 301 is controlled to move close to the axis position, and the stirring scraper 302 moves to stir the solution to accelerate the precipitation of crystals. After the crystals are precipitated, the opening and closing baffle 202 is controlled to move horizontally in the opposite direction to leave the filter port 201. The filter port 201 is opened, and the solution without precipitated crystals falls into the crystallization chamber of the lower layer. The driving block 301 is adjusted to move away from the axis so that one side of the stirring scraper 302 is in contact with the inner wall of the crystallization cylinder 1. The stirring scraper 302 moves to scrape and clean the crystals attached to the inner wall. After the crystallization operation in the upper crystallization chamber is completed, solution can be continuously added thereto to maintain the continuous operation of crystallization. Specific embodiment 2

[0030] See also Figure 1-6 On the basis of the specific embodiment 1, specifically, a feed port is provided on the upper surface of the crystallization cylinder 1, a feed pipe 101 is fixedly connected to the surface of the feed port, the solution enters the crystallization cavity of the upper layer through the feed pipe 101, a plurality of support columns 102 are fixedly connected to the side surface of the crystallization cylinder 1, a discharge port is provided at the lower end of the crystallization cylinder 1, a discharge pipe 103 is fixedly connected to the surface of the discharge port, and the solution after multi-layer crystallization is discharged through the discharge pipe 103.

[0031] Furthermore, the partition assembly 2 also includes a partition plate 204 fixedly connected to the inner wall of the crystallization cylinder 1, and an adjustment chamber connected to the filter port 201 is opened inside the partition plate 204, and a guide groove 205 is opened on the inner wall of the adjustment chamber; an opening and closing transmission block 206 is slidably arranged inside the guide groove 205, and the movement of the opening and closing transmission block 206 drives the opening and closing baffle 202 to move, and a vertical support plate 207 is symmetrically fixedly connected to one side of the opening and closing transmission block 206; an electric push rod 208 is fixedly installed on an inner wall of the guide groove 205, and one end of the electric push rod 208 is fixedly connected to the opening and closing transmission block 206, and the electric push rod 208 is used to drive the opening and closing transmission block 206 to move horizontally.

[0032] Furthermore, one end of the adjusting link 203 is rotatably connected to the lower surface of the opening and closing baffle 202 through an ear plate, and the other end of the adjusting link 203 is rotatably connected to a side surface of the opening and closing transmission block 206. An arc spring 209 is fixedly connected between the adjusting link 203 and the corresponding vertical support plate 207, and the two opposite sides of the filter port 201 and the opening and closing baffle 202 are both inclined sliding surface structures. The inclined sliding surface of the opening and closing baffle 202 is used to slide along the inclined sliding surface of the filter port 201, which facilitates sealing.

[0033] The operation process of this embodiment is as follows: when it is necessary to close the filter port 201 for stirring crystallization, the electric push rod 208 is started to drive the opening and closing transmission block 206 to move horizontally along the guide slide groove 205, and the opening and closing baffle 202 is driven to move horizontally synchronously under the connection action of the adjusting connecting rod 203. When one end of the opening and closing baffle 202 is close to the inner wall of the adjusting chamber, the opening and closing transmission block 206 continues to move horizontally, and the opening and closing baffle 202 is squeezed, so that the adjusting connecting rod 203 rotates, and the arc spring 209 is compressed. At the same time, the inclined sliding surface on one side of the opening and closing baffle 202 moves upward along the inclined sliding surface of the filter port 201 until the opening and closing baffle 202 is in close contact with the filter plate inside the filter port 201, so that the filter port 201 is completely blocked.

[0034] When it is necessary to open the filter port 201 to allow the solution to flow into the lower crystallization chamber, the electric push rod 208 drives the opening and closing transmission block 206 to move horizontally in the opposite direction along the guide slide groove 205, and the inclined sliding surface on the other side of the opening and closing baffle 202 moves downward along the inclined sliding surface of the filter port 201. Under the elastic recovery action of the arc spring 209, the adjusting connecting rod 203 rotates in the opposite direction until it leaves the filter port 201, and moves horizontally in the opposite direction synchronously with the opening and closing transmission block 206. The filter port 201 is opened, and the solution flows into the lower filter port 201. Finally, the waste liquid that cannot precipitate crystals is discharged through the discharge pipe 103.

[0036] See also Figure 1-6 On the basis of the first and second specific embodiments, specifically, the stirring assembly 3 also includes a support rod fixedly connected to the upper surface of the partition plate 204, one end of the support rod is rotatably connected to a support disc 303, a through hole 304 is provided on the surface of the support disc 303, and the solution flows down through the filter port 201 of the upper layer and is discharged through the through hole 304, a plurality of transmission chutes 305 are provided on the surface of the support disc 303, an adjustment transmission block 301 is slidably arranged inside the corresponding transmission chutes 305, the adjustment transmission block 301 moves horizontally along the transmission chutes 305, and the position of the stirring scraper 302 is adjusted, an adjustment transmission plate 306 is rotatably connected to the upper surface of the support disc 303, and a plurality of L-shaped transmission connecting rods 308 are rotatably connected to the upper surface of the corresponding adjustment transmission block 301, and the adjustment transmission plate 306 rotates to push and pull the L-shaped transmission connecting rod 308, thereby driving the adjustment transmission block 301 to move horizontally.

[0037] Furthermore, a driving motor 307 is fixedly installed on the top of the crystallization cylinder 1 and the lower surface of the corresponding partition plate 204 , and the output shaft of the driving motor 307 is fixedly connected to the adjustment transmission plate 306 .

[0038] The operation process of this embodiment is: when stirring is required to accelerate crystallization, the drive motor 307 is started to drive the adjustment transmission plate 306 to rotate. During this process, the adjustment transmission plate 306 rotates and pulls the L-shaped transmission connecting rod 308. The adjustment transmission block 301 is pulled horizontally by the L-shaped transmission connecting rod 308 and moves toward the position close to the axis until it is tightly attached to the side of the transmission slide 305 close to the axis. As the adjustment transmission plate 306 continues to rotate, it drives the support disc 303 to rotate synchronously, so that the stirring scraper 302 rotates synchronously to perform the stirring operation.

[0039] When wall scraping and cleaning is required, the driving motor 307 drives the adjusting transmission plate 306 to rotate in the opposite direction. The adjusting transmission plate 306 rotates and pushes the L-shaped transmission connecting rod 308, so that the adjusting transmission block 301 moves horizontally in the opposite direction and moves away from the axis position until it is in close contact with the side of the transmission slide 305 away from the axis. As the adjusting transmission plate 306 continues to rotate, the stirring scraper 302 rotates along the inner wall of the crystallization chamber to scrape and clean the crystals attached to the inner wall.
