Therefore, when circulating and crystallizing at high viscosity, a large amount of crystals will be adsorbed on the inner wall of the crystallizer, and it is difficult to automatically and timely adjust the distance between the circulating impact ports according to the viscosity, so it is difficult to realize the synchronous self-adjustment function of the impact force on the top inclined surface, the side surface and the bottom inclined surface, the crystallization residue amount increases significantly, and the raw material waste cost is relatively high. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solution: a forced circulation evaporation crystallizer, which includes a crystallization tank, a spray pipe, a micro electric cylinder and a controller.

[0014] The technical effects and advantages of the present invention:

[0015] 1. Through the crystallization mechanism with adjustable multi-faceted nozzle spacing of the present invention, when the crystallization liquid shows high viscosity, the micro electric cylinder is used to push the hinge block upward. The two linkage rods drive the tops of the two hinge sleeve rods to move upward respectively. The two upper inclined baffles adjust the spraying gap of the top inclined surface of the strip-shaped spray hole, and the two side baffles adjust the spraying gap at the side position of the strip-shaped spray hole. At the same time, the two lower inclined baffles adjust the spraying gap of the lower inclined surface of the strip-shaped spray hole. The spraying spacing of the circulating strip-shaped spray hole can be automatically and timely adjusted according to the viscosity of the crystallization liquid, so as to realize the synchronous self-adjustment function of the impact force on the top inclined surface, side and bottom inclined surface. The crystallization residue amount is greatly reduced, and the cost of raw material crystallization waste is greatly reduced.

[0016] 2. The present invention adopts a head and tail viscosity calibration component. The circulating pump machine transports the crystallization liquid inside the crystallization tank into the suction pipe. The head viscosity sensor can detect the viscosity of the crystallization liquid at the head, and it is poured into the docking pipe through the connecting pipe. The tail viscosity sensor detects the tail viscosity of the crystallization liquid. The docking pipe is transported into the rotating pipe, and is poured into the spray pipe through the communicating pipe. When the viscosity values detected by the head viscosity sensor and the tail viscosity sensor both exceed the viscosity value set by the controller, it means that the crystallization liquid has a high viscosity problem. The spraying distance of the circular spray holes can be automatically adjusted in a timely manner according to the viscosity of the crystallization liquid, realizing a synchronous self-adjustment function of large-area impact force for the strip-shaped spray holes, and significantly reducing the crystallization residue amount.

[0017] 3. The present invention passes through a position-changing component. The position-changing motor drives the rotating pipe to rotate forward one circle and then reverse one circle. The rotating pipe drives a plurality of communicating pipes to rotate forward one circle and then reverse one circle. The strip-shaped spray holes can use the crystallization liquid with high viscosity to impact the high-viscosity crystallization residue on the inner wall of the crystallization tank, realizing position-changing processing in different directions, and significantly reducing the crystallization residue amount on the inner wall of the crystallization tank.

[0037] The working principle of the forced circulation evaporation crystallizer of the present invention is as follows:

[0038] Step 1: During evaporation crystallization, the two water inlet ports 18 are docked on the crystallization liquid conveying pipeline, and the crystallization liquid is conveyed into the crystallization tank 1 for loading. By starting the resistance heater 31, the bottom of the crystallization tank 1 is heated, so that steam evaporation is carried out during heating, and the steam is discharged upward along the steam pipe 34.

[0039] Step 2: When calibrating the viscosities at the head and the tail, start the circulating pump 26 through the controller 17. The circulating pump 26 conveys the crystallization liquid inside the crystallization tank 1 into the suction pipe 27. The head viscosity sensor 28 can detect the viscosity of the crystallization liquid at the head, and then it enters the connecting pipe 25 along the circulating pump 26 through the pressurization of the suction pipe 27. It is poured into the docking pipe 23 through the connecting pipe 25, and the tail viscosity sensor 24 detects the tail viscosity of the crystallization liquid. In this way, it is poured into the docking pipe 23 through the connecting pipe 25, conveyed into the rotating pipe 21 through the docking pipe 23, conveyed into multiple communicating pipes 20 through the rotating pipe 21, poured into the nozzle 2 through the communicating pipes 20, enters the strip-shaped spray holes 16 through the nozzle 2, and is sprayed and circulated into the crystallization tank 1 through the strip-shaped spray holes 16. When the viscosity values detected by both the head viscosity sensor 28 and the tail viscosity sensor 24 exceed the viscosity value set by the controller 17, it indicates that there is a problem of high viscosity of the crystallization liquid, and the micro electric cylinder 3 is started through the controller 17.

[0040] Step 3: When crystallizing with adjustable multi-faceted nozzle spacing, push the hinge block 4 upward through the micro electric cylinder 3. The hinge block 4 drives the two linkage rods 5 to move upward. The two linkage rods 5 respectively drive the tops of the two hinge sleeve rods 6 to move upward, and the hinge sleeve rods 6 drive the connecting shaft 7 to move to the right, and the other connecting shaft 7 moves to the left. The two connecting shafts 7 approach each other. The connecting shaft 7 drives the socket slider 8 to move to the right. The socket slider 8 moves to the right along the outer wall of the guide rod 14, and the socket slider 8 can also move to the right along the outer wall of the sliding frame 15. The socket slider 8 drives the sensing block 12 to move to the right, and the sensing block 12 approaches the position of the distance sensor 13. At the same time, the two upper inclined baffles 9 approach each other, the two side baffles 10 approach each other, and the two lower inclined baffles 11 also approach synchronously. In this way, the two upper inclined baffles 9 adjust the spraying gap of the top inclined surface of the strip-shaped spray holes 16, the two side baffles 10 adjust the spraying gap at the side position of the strip-shaped spray holes 16, and the two lower inclined baffles 11 adjust the spraying gap of the lower inclined surface of the strip-shaped spray holes 16.

[0041] The distance sensor 13 senses the distance between the sensing block 12 and the distance sensor 13. When the distance value sensed by the distance sensor 13 is the same as the distance value set by the controller 17, the micro electric cylinder 3 is closed through the controller 17. The crystallization liquid sprayed out from the strip-shaped spray holes 16 can increase the spraying impact pressure, so that the crystallization liquid can achieve a large-area enhanced impact on the upper inclined surface, the side surface, and the lower inclined surface of the inner wall of the crystallization tank 1, and immediately impact and remove the high-viscosity crystals adhered to the inner wall of the crystallization tank 1.

[0042] Step 4: During the displacement, the support block 33 is supported by the crystallization tank 1, the support block 33 supports the displacement motor 32, the displacement motor 32 drives the rotating pipe 21 to rotate forward one circle and then reverse one circle, the rotating pipe 21 drives a plurality of connecting pipes 20 to rotate forward one circle and then reverse one circle, the connecting pipes 20 drive the spray pipe 2 to rotate forward one circle and then reverse one circle, and the strip-shaped spray holes 16 on the spray pipe 2 can use the highly viscous crystallization liquid to impact the high-viscosity crystallization residues on the inner wall of the crystallization tank 1. In this way, the spraying gap of the strip-shaped spray holes 16 can be automatically adjusted according to the viscosity, thereby increasing the spraying impact force of the crystallization liquid inside the strip-shaped spray holes 16.

Conventional equipment can be used.
