Description

Technical Field

[0001] The present invention relates to the technical field of crystallization, and more specifically, to a forced circulation evaporation crystallizer. Background Art

[0002] The forced circulation evaporation crystallizer plays an important role in multiple fields such as industrial wastewater treatment, material crystallization and concentration due to its high efficiency, reliability and strong adaptability, and is one of the indispensable important devices in modern industrial production.

[0003] However, in the prior art, during the forced circulation evaporation crystallization process of the crystallizer, after the inside of the crystallizer is heated, the liquid will be concentrated and crystallized inside, and the viscosity of the liquid will increase significantly. 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, resulting in a significant increase in the crystallization residue and a relatively high cost of raw material waste. 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, including a crystallization tank, a spray pipe, a micro electric cylinder and a controller. The spray pipe is located inside the crystallization tank. The micro electric cylinder is fixed on the inclined surface of the spray pipe, and a multi-faceted spray port distance adjustable crystallization mechanism is arranged at the output end of the micro electric cylinder. The multi-faceted spray port distance adjustable crystallization mechanism includes a hinge block fixedly installed at the output end of the micro electric cylinder, and two linkage rods are fixedly connected to the inner wall of the hinge block. The outer wall of each linkage rod is rotatably connected to a hinge sleeve rod. A connecting shaft is rotatably connected to the inner wall of the hinge sleeve rod at a position far from the linkage rod. One end of the connecting shaft is fixedly installed with a socket slider, and the bottom end of the socket slider is fixedly connected with an upper inclined baffle.

[0005] The bottom end of the upper inclined baffle is fixedly connected with a side baffle, and the bottom end of the side baffle is fixedly connected with a lower inclined baffle. A head and tail viscosity calibration component is arranged on one side of the spray pipe. The center point of the linkage rod is higher than the center point of the connecting shaft, and the two socket sliders are symmetrically arranged about the middle of the spray pipe. The two upper inclined baffles are slidably connected to the spray pipe, the two side baffles are slidably connected to the spray pipe, and the two lower inclined baffles are slidably connected to the spray pipe. The micro electric cylinder is electrically connected to the controller.

[0006] The inner wall of the socket slider is fixedly connected with an induction block, and a distance sensor is arranged on one side of the induction block. The controller is electrically connected with the distance sensor, and the distance sensor is fixedly connected with another socket slider. A guide rod is arranged at the position above the induction block on the inner wall of the socket slider. Both socket sliders are slidably connected with the guide rod.

[0007] Preferably, strip-shaped spray holes are formed in the inner wall of the spray pipe. The controller is fixed on the outer wall of the crystallization tank. Water inlet ports are arranged above and below the controller, and both water inlet ports are fixedly connected with the crystallization tank. A sliding strip is slidably connected to one side of the lower inclined baffle, and the sliding strip is fixedly connected with the spray pipe.

[0008] When the present technology is used for crystallization, the micro electric cylinder is used to push the hinge block upward. The two linkage rods respectively drive the tops of the two hinge sleeve rods to move upward, and the two connecting shafts approach each other. The socket slider moves rightward along the outer wall of the guide rod. The socket slider drives the induction block to move rightward. 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.

[0009] Preferably, the head and tail viscosity calibration assembly includes a plurality of communicating pipes fixedly arranged on one side of the spray pipe. One end of each communicating pipe is provided with a rotating pipe, and all the communicating pipes are communicated with the rotating pipe. A connecting hose is fixedly communicated with the outer wall of the rotating pipe. The connecting hose is fixedly connected with the crystallization tank. The top end of the connecting hose is fixedly communicated with a docking pipe. A connecting pipe is fixedly installed at the top end of the docking pipe. A tail viscosity sensor is fixedly connected to one side of the outer wall of the connecting pipe. The tail viscosity sensor is electrically connected with the controller. A circulating pump is fixedly installed at the bottom end of the connecting pipe. The circulating pump is electrically connected with the controller.

[0010] The input end of the circulating pump is fixedly communicated with a suction pipe. A head viscosity sensor is fixedly connected to one side of the outer wall of the suction pipe. One end of the suction pipe is fixedly communicated with a lower discharge tank. A valve is threadedly communicated with the bottom end of the lower discharge tank.

The inner walls of the communicating pipes and the rotating pipe are both smooth surfaces. The inner walls of the suction pipe and the lower discharge tank are both smooth surfaces. The resistance heater is used to heat the crystallization tank.

[0011] When this technology is used for crystallization, the circulating pump makes the crystallization liquid inside the crystallization tank be transported into the suction pipe. The viscosity sensor at the head can detect the viscosity of the crystallization liquid at the head, and it is poured into the docking pipe through the connecting pipe. The viscosity of the crystallization liquid is detected at the tail through the viscosity sensor at the tail. The docking pipe is transported into the rotating pipe, and then through the rotating pipe into multiple communicating pipes, and enters the strip-shaped spray holes through the spray pipe, and is sprayed and circulated into the crystallization tank through the strip-shaped spray holes.

[0012] Preferably, a displacement assembly is provided at the top of the rotating pipe. The displacement assembly includes a displacement motor provided at the top of the rotating pipe.

[0013] When this technology is used for crystallization, the displacement motor drives the rotating pipe to rotate forward one circle and then reverse one circle. The rotating pipe drives the multiple communicating pipes to rotate forward one circle and then reverse one circle. The communicating pipes drive the spray pipe to rotate forward one circle and then reverse one circle. The strip-shaped spray holes on the spray pipe can use the highly viscous crystallization liquid to impact the high-viscosity crystallization residues on the inner wall of the crystallization tank.

[0014] The technical effects and advantages of the present invention: 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 surface and bottom inclined surface. The crystallization residue amount is greatly reduced, and the cost of raw material crystallization waste is greatly reduced.

[0015] 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, which 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 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 indicates that the crystallization liquid has a high viscosity problem. The spraying distance of the circulating strip-shaped spray holes can be automatically adjusted in a timely manner according to the viscosity of the crystallization liquid, realizing a large-area impact synchronization self-adjustment function for the strip-shaped spray holes, and significantly reducing the crystallization residue amount.

[0016] 3. The present invention uses a displacement component. The displacement motor drives the rotating pipe to rotate forward one circle and then reverse one circle. The rotating pipe drives multiple communicating pipes to rotate forward one circle and then reverse one circle. The strip-shaped spray holes can use the high-viscosity crystallization liquid to impact the high-viscosity crystallization residues on the inner wall of the crystallization tank, realizing displacement processing in different directions, and significantly reducing the crystallization residue amount on the inner wall of the crystallization tank.

The inner walls of the suction pipe 27 and the lower discharge tank 29 are both smooth surfaces. The resistance heater 31 is used to heat the crystallization tank 1.

[0035] In this embodiment, as shown in the appendix Figure 9 As shown in the figure, a displacement assembly is provided at the top end of the rotating pipe 21. The displacement assembly includes a displacement motor 32 arranged at the top end of the rotating pipe 21. The displacement motor 32 is electrically connected to the controller 17, and the output end of the displacement motor 32 is fixedly connected to the rotating pipe 21; a support block 33 is installed on one side of the displacement motor 32, and both the crystallization tank 1 and the displacement motor 32 are fixedly connected to the support block 33. A steam pipe 34 is provided on the other side of the displacement motor 32, and the steam pipe 34 is fixedly communicated with the crystallization tank 1. The displacement motor 32 is used to drive the rotating pipe 21 to rotate, and the output end of the displacement motor 32 is rotatably connected to the crystallization tank 1.

[0036] The working principle of the forced circulation evaporation crystallizer of the present invention is as follows: 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 to heat the bottom of the crystallization tank 1, steam evaporation is carried out in this way, and the steam is discharged upward along the steam pipe 34.

[0037] Step 2: When calibrating the viscosities at the head and the tail, start the circulation pump 26 through the controller 17. The circulation pump 26 transports 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 circulation pump 26 through the pressurization of the suction pipe 27. It is poured into the docking pipe 23 through the connecting pipe 25. The tail viscosity sensor 24 detects the viscosity of the crystallization liquid at the tail. In this way, it is poured into the docking pipe 23 through the connecting pipe 25, transported into the rotating pipe 21 through the docking pipe 23, transported into multiple communicating pipes 20 through the rotating pipe 21, poured into the spray pipe 2 through the communicating pipes 20, enters the strip-shaped spray holes 16 through the spray pipe 2, and is sprayed and circulated into the crystallization tank 1 through the strip-shaped spray holes 16. When the viscosity values detected by the head viscosity sensor 28 and the tail viscosity sensor 24 both 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.

[0038] Step 3: When crystallizing with adjustable multi-faceted nozzle spacing, the micro-electric cylinder 3 is pushed to move the hinge block 4 upward. 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, while the other connecting shaft 7 moves to the left, and 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 induction block 12 to move to the right, and the induction 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.

[0039] The distance sensor 13 senses the distance between the induction 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.

[0040] 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 the 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.
