Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a chemical crystallization control device. Background Technology

[0002] In chemical production, crystallization is a crucial method for achieving substance separation and purification. The quality of the crystallized product, such as crystal size distribution and crystal form, has a vital impact on the performance and application of subsequent products. Therefore, developing a device capable of precisely controlling the crystallization process to improve product quality and production efficiency is of significant practical importance.

[0003] The existing device CN216149070U is a crystallization apparatus for chemical solution crystallization, comprising a crystallization tank. A drive motor is fixedly installed in the middle of the upper surface of the crystallization tank. The motor shaft of the drive motor passes through the inner wall of the top of the crystallization tank and is fixedly connected to a rotating rod. Stirring rods are fixedly installed on both the left and right sides of the lower end of the rotating rod. This invention, through the combination of a discharge pipe, a heating pipe, and a feed pipe, can introduce the chemical solution into the crystallization tank. A gas guide pipe can introduce the high-temperature water vapor generated during the crystallization process into a preheating box, further preheating the chemical solution inside the heating pipe. This saves energy and improves the crystallization efficiency of the chemical solution. Through the combination of a liquid pump, a connecting pipe, and a nozzle, water generated by the liquefaction of water vapor in the preheating box can be extracted and introduced into the crystallization tank for cleaning, which is convenient, fast, and saves water resources.

[0004] The aforementioned devices are difficult to precisely control the temperature during the crystallization process. Temperature fluctuations can lead to uneven crystal size distribution, affecting the quality of the crystallized product. Furthermore, the aforementioned devices cannot flexibly adjust the concentration of the chemical solution, making it difficult to meet the specific requirements of different crystallization processes for solution concentration. Utility Model Content

[0005] The purpose of this invention is to solve the problems of inaccurate temperature control and inflexible concentration regulation in existing devices, and to propose a chemical crystallization regulation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a chemical crystallization control device, comprising a cylinder and a temperature control component. The cylinder has an internal mounting groove, and the temperature control component is fixedly connected to the inner wall of the mounting groove. The temperature control component includes a heating tube fixedly connected to the inner wall of the mounting groove, and a heating wire fixedly connected inside the heating tube. A condenser tube is fixedly connected to the inner wall of the mounting groove. A slot is formed on the surface of the cylinder, and the surface of the water inlet end of the condenser tube is inserted into the inner wall of the slot. A threaded groove is formed at the water inlet end of the condenser tube, and a sealing cap is threadedly connected to the surface of the threaded groove. A temperature detection sensor is fixedly connected to the inner wall of the cylinder.

[0007] Furthermore, the heating tubes are fixedly distributed at the upper end of the mounting groove, and the condensing tubes are fixedly distributed at the lower end of the mounting groove. The heating tubes and condensing tubes are staggered and intersecting inside the mounting groove.

[0008] Furthermore, a control center is fixedly connected to the front of the cylinder, and a concentration control component is fixedly connected to the surface of the cylinder.

[0009] Furthermore, the concentration control component includes a material box fixedly connected to the surface of the cylinder, and the material box has two material hoppers inside.

[0010] Furthermore, two A-type conveying pipes are inserted and connected to the top of the material box, and a feeding pump is fixedly connected to one end of each of the two A-type conveying pipes.

[0011] Furthermore, each of the two feeding pumps is fixedly connected to a B conveying pipe at its other end, and the contact ends of the A and B conveying pipes with the feeding pumps are fixedly connected with sealing rings.

[0012] Furthermore, the surface of the B conveying pipe is fixedly and inserted into the top of the cylinder, and three load-bearing columns are fixedly connected to the bottom of the cylinder.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, a temperature control component is set up, and a temperature detection sensor is used to monitor the temperature inside the cylinder in real time. When the detected temperature is lower than the preset temperature required for the crystallization process, the control center precisely adjusts the heating power of the heating wire according to the preset program, and heats the material inside the cylinder through the heating tube. When the temperature is higher than the preset value, the operator connects the condenser tube to an external cooling water source. The coolant flows in the condenser tube and quickly removes excess heat to achieve cooling. When the condenser tube is not in use, the sealing cap is threaded into the threaded groove to prevent foreign objects from entering the slot and ensure the normal operation of the device. The staggered distribution of the heating tube and condenser tube greatly increases the heat exchange area, making the temperature distribution inside the cylinder more uniform, avoiding local overheating or overcooling, effectively reducing the impact of temperature fluctuations on crystal growth, ensuring the uniformity of crystal particle size distribution, significantly improving the quality of the crystallized product, and meeting the strict requirements of high-end chemical products for crystallization quality.

[0015] 2. In this invention, by setting up a concentration control component, different materials in the two hoppers of the material tank can be precisely transported into the cylinder through conveying pipes A and B, according to the requirements of different crystallization processes, using a feeding pump. A sealing ring prevents material leakage, ensuring the stability of the conveying process. By controlling the conveying volume and time of the feeding pump, the concentration of the chemical solution in the cylinder can be flexibly adjusted to meet diverse crystallization process requirements, improving the applicability and production efficiency of the device.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a chemical crystallization control device, including a cylinder 1 and a temperature control component 2. The cylinder 1 has an installation groove inside, and the temperature control component 2 is fixedly connected to the inner wall of the installation groove.

[0024] The specific settings and functions of its temperature control component 2 and concentration control component 4 will be explained below.

[0025] In this embodiment: the temperature control component 2 includes a heating tube 21 fixedly connected to the inner wall of the mounting slot, an electric heating wire 22 fixedly connected inside the heating tube 21, a condenser tube 23 fixedly connected to the inner wall of the mounting slot, a slot is opened on the surface of the cylinder 1, the surface of the water inlet end of the condenser tube 23 is inserted into the inner wall of the slot, a threaded groove 24 is opened on the water inlet end of the condenser tube 23, a sealing cap 25 is threadedly connected to the surface of the threaded groove 24, and a temperature detection sensor 26 is fixedly connected to the inner wall of the cylinder 1.

[0026] The effects achieved by the above components are as follows: by setting the temperature detection sensor 26, the temperature inside the cylinder 1 can be monitored in real time. When the detected temperature is lower than the preset crystallization temperature, the control system supplies power to the heating wire 22 to make it heat up, and heats up the material inside the cylinder 1 through the heating tube 21. When the temperature is higher than the preset value, the condenser tube 23 is connected to an external cooling water source. The coolant flows in the condenser tube 23 to carry away the excess heat and achieve cooling.

[0027] Specifically, the heating tubes 21 are fixedly distributed at the upper end of the mounting tank, and the condenser tubes 23 are fixedly distributed at the lower end of the mounting tank. The heating tubes 21 and the condenser tubes 23 are staggered and intersected inside the mounting tank.

[0028] The effect achieved by the above components is as follows: by setting a staggered and cross-distributed pattern, the heat exchange area between the heating tube 21 and the condenser tube 23 is increased, the temperature distribution inside the cylinder 1 is more uniform, the local temperature is avoided to be too high or too low, the accuracy of temperature control is improved, and the crystallization process is ensured to proceed stably.

[0029] Specifically, a control center 3 is fixedly connected to the front of the cylinder 1, and a concentration control component 4 is fixedly connected to the surface of the cylinder 1.

[0030] The effects achieved by the above components are as follows: by setting up the control center 3, the temperature control component 2 and the concentration control component 4 can be centrally controlled, which makes it convenient for operators to flexibly adjust the operating parameters of the device according to different crystallization process requirements; the concentration control component 4 provides hardware support for adjusting the concentration of the chemical solution in the cylinder 1.

[0031] Specifically, the concentration control component 4 includes a material box 41 fixedly connected to the surface of the cylinder 1, and the material box 41 has two material hoppers 42 inside.

[0032] The effect achieved by the above components is that by setting up the material box 41 and two material bins 42, two different materials can be stored at the same time, providing a material basis for flexibly adjusting the concentration of chemical solutions and meeting the needs of different crystallization processes for adding multiple materials.

[0033] Specifically, two A-conveying pipes 43 are inserted and connected to the top of the material box 41, and a feeding pump 44 is fixedly connected to one end of each of the two A-conveying pipes 43.

[0034] The effect achieved by the above components is as follows: by setting up the A conveying pipe 43 and the feeding pump 44, the feeding pump 44 can extract the material in the silo 42 through the A conveying pipe 43, accurately control the material conveying amount and conveying speed, and realize the precise control of the concentration of chemical solution in the cylinder 1.

[0035] Specifically, each of the two feed pumps 44 has a B conveying pipe 45 fixedly connected to its other end, and a sealing ring 46 is fixedly connected to the contact end of the A conveying pipe 43 and the B conveying pipe 45 with the feed pump 44.

[0036] The effect achieved by the above components is as follows: by setting up the B conveying pipe 45, the material pumped by the feed pump 44 is smoothly conveyed into the cylinder 1, and the sealing ring 46 prevents the material from leaking during the conveying process, ensuring the safety and stability of the conveying process.

[0037] Specifically, the surface of the B conveying pipe 45 is fixedly and inserted into the top of the cylinder 1, and three load-bearing columns 5 are fixedly connected to the bottom of the cylinder 1.

[0038] The effects achieved by the above components are as follows: by setting the connection method between the B conveying pipe 45 and the cylinder 1, the material can be stably conveyed into the cylinder 1; the load-bearing column 5 provides stable support for the cylinder 1, ensuring that the device remains stable during operation.

[0039] Working principle: By setting up a temperature control component, the temperature inside the cylinder 1 is monitored in real time by a temperature detection sensor 26. When the detected temperature is lower than the preset temperature required for the crystallization process, the control center precisely adjusts the heating power of the heating wire 22 according to the preset program, and heats the material inside the cylinder 1 through the heating tube 21. When the temperature is higher than the preset value, the operator connects the condenser tube 23 to an external cooling water source. The coolant flows in the condenser tube 23, quickly removing excess heat and achieving cooling. When the condenser tube 23 is not in use, the sealing cap 25 is threaded into the threaded groove 24 to prevent foreign objects from entering the slot and ensure the normal operation of the device. The staggered distribution of the heating tube 21 and the condenser tube 23 greatly increases the heat exchange area, making the temperature distribution inside the cylinder 1 more uniform, avoiding local overheating or overcooling, effectively reducing the impact of temperature fluctuations on crystal growth, ensuring the uniformity of crystal particle size distribution, significantly improving the quality of the crystallized product, and meeting the strict requirements of high-end chemical products for crystallization quality.

[0040] By setting up the concentration control component 4, different materials in the two hoppers 42 within the material tank 41 can be precisely transported into the cylinder 1 via conveying pipes A 43 and B 45 using the feed pump 44, according to the requirements of different crystallization processes. The sealing ring 46 prevents material leakage and ensures the stability of the conveying process. By controlling the conveying volume and time of the feed pump 44, the concentration of the chemical solution in the cylinder 1 can be flexibly adjusted to meet diverse crystallization process requirements, improving the applicability and production efficiency of the equipment.
