Description

Technical Field

[0001] The utility model relates to the technical field of crystallization devices, in particular to an anti-blocking crystallization device. Background Art

[0002] Crystallization is the process of cooling a hot saturated solution so that the solubility of the solute in the solution decreases and the solution gradually condenses to form crystal nuclei, which then slowly develop into crystals with the crystal nuclei as the condensation points.

[0003] In industrial production, a crystallization apparatus with a crystallization tank is a key piece of equipment for the crystallization process. Currently, most crystallization apparatuses on the market are horizontal, fixed structures with a bracket that securely connects and supports the crystallization tank. When using this type of crystallization apparatus, the crystallization tank must be removed from the fixed bracket before unloading. Because the unloading area is often fixed, the unloaded crystallization tank must also be moved before unloading. This cumbersome process of disassembling and moving the crystallization tank makes the unloading process time-consuming, slow, and laborious.

[0004] In addition, as a container that provides a crystallization site, the crystallization tank is usually provided with a solution outlet. After the crystallization is completed, the mother liquor can be discharged through the solution outlet to separate it from the formed crystals. However, during the crystallization process, the solution outlet is easily blocked by crystals, making solid-liquid separation difficult. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-blocking crystallization device, which has an anti-blocking function and is convenient for separating crystals from mother liquor.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0008] Furthermore, the anti-blocking rod includes a head and a straight rod portion, the head is located outside the crystallization tank, the straight rod portion is vertically arranged and movably penetrates the crystallization tank, the upper end of the straight rod portion is fixedly connected to the head, and the lower end of the straight rod portion blocks the drainage hole.

[0009] Furthermore, the lower end of the straight rod portion is threadedly connected to the inner wall of the drainage through hole.

[0010] Furthermore, anti-slip stripes are provided on the outer wall of the head.

[0011] Furthermore, the crystallization tank includes a tank body and a cover body, the crystallization cavity is provided inside the tank body, and the top of the crystallization cavity has an opening, and the cover body is detachably connected to the tank body by a lock and closes the top opening of the crystallization cavity; a jacket is provided on the outside of the tank body, a liquid storage cavity is formed between the inner wall of the jacket and the outer wall of the tank body, and a liquid inlet pipe and a liquid outlet pipe are connected to the outside of the jacket, and the liquid inlet pipe and the liquid outlet pipe are respectively communicated with the liquid storage cavity.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0027] like Figure 1-3 As shown, the utility model discloses an anti-blocking crystallization device, including a crystallization tank 1 and an anti-blocking rod 2. A crystallization cavity 111 is provided in the crystallization tank 1, and a drain pipe 13 is provided below the crystallization tank 1. The crystallization cavity 111 is used to hold the solution to be crystallized and provide a place for the crystallization process to occur. A drain hole 112 for discharging the mother liquid is provided at the bottom of the crystallization cavity 111. The drain pipe 13 is connected to the drain hole 112 and can lead out the mother liquid in the crystallization cavity 111. A drain control valve 131 is provided on the drain pipe 13. By opening and closing the drain control valve 131, the mother liquid discharge operation can be started or stopped. The anti-blocking rod 2 is movably provided in the crystallization tank 1, and one end of the anti-blocking rod 2 is located outside the crystallization tank 1, and the other end can be withdrawn to block the drain hole 112.

[0028] Before pouring the solution to be crystallized, the portion of the anti-blocking rod 2 located outside the crystallization tank 1 can be used to drive the end of the anti-blocking rod 2 to block the drainage hole 112 inside the crystallization cavity 111, thereby preventing the crystals formed in the subsequent crystallization process from blocking the drainage hole 112 and causing difficulties in solid-liquid separation. After the crystallization is completed, the anti-blocking rod 2 can be again removed from the portion of the anti-blocking rod 2 located outside the crystallization tank 1, driving the end of the anti-blocking rod 2 away from the drainage hole 112 and releasing the blockage of the drainage hole 112. After the anti-blocking rod 2 is removed, the drainage hole 112 is unblocked, which not only reduces the difficulty of subsequent solid-liquid separation, but also shortens the solid-liquid separation time and improves work efficiency. Compared with conventional crystallization devices, the solid-liquid separation time is shortened by more than 40%.

[0029] More specifically, the crystallization tank 1 includes a tank body 11 and a cover 12. The tank body 11 is provided with the above-mentioned crystallization cavity 111. The top of the crystallization cavity 111 has an opening for feeding and unloading. The cover 12 is detachably connected to the tank body 11 and closes the top opening of the crystallization cavity 111. A jacket 15 is provided on the outside of the tank body 11. A liquid storage cavity 16 is formed between the inner wall of the jacket 15 and the outer wall of the tank body 11. A liquid inlet pipe 17 and a liquid outlet pipe 18 are connected to the outside of the jacket 15. The liquid inlet pipe 17 and the liquid outlet pipe 18 are respectively connected to the liquid storage cavity 16. Through the liquid inlet pipe 17 and the liquid outlet pipe 18, an external cooling medium pipeline can be connected to guide chilled water or refrigerant into the liquid storage cavity 16, thereby achieving the purpose of lowering the temperature of the solution inside the crystallization cavity 111 and promoting the precipitation of solutes to form crystals. The liquid inlet pipe 17 and the liquid outlet pipe 18 are both provided with quick-connect connectors for quick connection and disconnection with the cooling medium pipeline, thus shortening the pipeline installation and removal time by more than 80%.

[0030] like Figure 4 As shown, the anti-blocking rod 2 includes a head 21 and a straight rod 22. The head 21 is located outside the crystallizer 1, and the straight rod 22 is vertically arranged and movably penetrates the crystallizer 1 along the vertical direction. The upper end of the straight rod 22 passes through the crystallizer 1 and is fixedly connected to the head 21. The lower end of the straight rod 22 extends into the drainage through hole 112 and blocks the drainage through hole 112. Through the head 21, when the cover 12 closes the crystallization cavity 111, the straight rod 22 can be operated and controlled to move up and down outside the crystallizer 1, and then the lower end of the straight rod 22 is inserted into the drainage through hole 112 for blocking. At this time, since the internal space of the drainage through hole 112 is occupied by the lower end of the straight rod 22, the drainage through hole 112 can be effectively prevented from being blocked by the crystallization material. The lower end of the straight rod 22 is also withdrawn from the drainage through hole 112 to release the blockage and restore the drainage function.

[0031] Preferably, the lower end of the straight rod 22 is threadedly connected to the inner wall of the drainage hole 112. The head 21 can be used to control the rotation of the straight rod 22, thereby screwing the lower end of the straight rod 22 into and out of the drainage hole 112. When the lower end of the straight rod 22 is screwed into the drainage hole 112, thus blocking the drainage hole 112, the anti-blocking rod 2 is not easily displaced. The outer wall of the head 21 of the anti-blocking rod 2 is provided with anti-slip stripes to increase friction and facilitate the rotation of the anti-blocking rod 2.

[0032] like Figure 5 As shown, the anti-blocking crystallization device also includes a crystallization support 3, which includes two upright frames 31 arranged on both sides of the crystallization tank 1. The two upright frames 31 are rotatably connected to the outer wall of the crystallization tank 1 around the same horizontal axis. After the lock 14 is opened to open the crystallization cavity 111, the crystallization tank 1 can be slowly turned along the horizontal axis to directly pour out the crystallized material without removing the crystallization tank 1 from the crystallization support 3. This saves time in installing and disassembling the crystallization tank 1 and speeds up the unloading process.

[0033] The stand 31 includes a tripod body 311 and a mounting base 312. The tripod body 311 is vertically arranged to ensure stable support. The mounting base 312 is fixedly connected to the upper position of the tripod body 311 and is rotatably connected to the crystallization tank 1. The stand 31 and the crystallization tank 1 are rotatably connected through a bearing to make the flip smooth. In addition to the stand 31, a reinforcement cross bar 33 is also provided in the crystallization support 3. The reinforcement cross bar 33 is arranged between the two stands 31 and is located below the crystallization tank 1, and the two ends of the reinforcement cross bar 33 are respectively fixedly connected to the tripod bodies 311 of the two stands 31, which can make the crystallization support 3 support more stable.

[0034] A plurality of universal wheels 32 are mounted on the bottom of the crystallization rack 3. After the mother liquor is drained, the crystallization tank 1 can be directly transferred to the unloading area for unloading via the crystallization rack 3 with universal wheels 32 without disassembling the crystallization tank 1. Therefore, no external mechanical or manual handling of the crystallization tank 1 is required, and unnecessary damage to the crystallization tank 1 during handling and unloading can be avoided.

[0035] In summary, the anti-blocking crystallization device has many advantages such as anti-blocking, quick connection to cooling medium pipeline, no need to disassemble, flippable, and movable. Compared with conventional fixed crystallization devices, the anti-blocking crystallization device can reduce the solid-liquid separation time by more than 40%, reduce the pipeline loading and unloading time by more than 80%, and reduce the unloading time by more than 70%, which can effectively improve work efficiency.
