Description

Technical Field

[0001] This utility model relates to the field of crystallization equipment technology, and in particular to a high-efficiency crystallization equipment for superphosphate. Background Technology

[0002] As a high-concentration water-soluble phosphate fertilizer, triple superphosphate plays a vital role in agricultural production. It provides crops with abundant phosphorus, promotes root growth, enhances crop resistance, and improves crop yield and quality. Therefore, it has a wide market demand. Currently, in the production process of triple superphosphate, the crystallization stage is the key step that determines product quality and production efficiency, which requires the use of triple superphosphate crystallization equipment.

[0003] Currently, most existing superphosphate crystallization equipment uses the following technologies to achieve its effect;

[0004] Solution supersaturation techniques include evaporation concentration and cooling.

[0005] Stirring and mixing technologies, including mechanical stirring and gas bubbling stirring;

[0006] Seed addition technology includes external seed introduction and internal seed generation;

[0007] Impurity removal technologies include filtration and ion exchange;

[0008] Currently, most existing superphosphate crystallization equipment only has one solution channel. The liquid flows through a single solution channel, which causes the external solution to come into contact with the cooling mechanism, while the internal solution cannot come into contact with the cooling mechanism. This results in uneven internal liquid temperature, leading to excessive local concentration and temperature differences, which affects crystallization efficiency. Utility Model Content

[0009] To address the shortcomings of existing technologies, this invention provides a high-efficiency crystallization device for superphosphate, solving the problem of low crystallization efficiency in existing crystallization equipment.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A high-efficiency crystallization device for superphosphate includes a crystallization chamber and a base plate. A PLC controller is fixedly connected to the top surface of the base plate, and four support rods are fixedly connected to the top surface of the base plate. A fixing sleeve is fixedly connected to one end of each support rod away from the base plate. The fixing sleeve is fixedly connected to the crystallization chamber. A crystallization mechanism for superphosphate crystallization is provided inside the crystallization chamber. A monitoring mechanism is provided on the surface of the crystallization chamber. An end cover is provided on the top of the crystallization chamber. The crystallization mechanism includes a top fixing plate, a bottom fixing plate, and a cooling pipe. The monitoring mechanism includes two second thermometers and one first thermometer.

[0012] Preferably, both the end cap and the crystallization chamber are provided with flange structures, and six bolt assemblies are adapted between the end cap and the crystallization chamber. The bolt assemblies include hexagonal bolts and hexagonal nuts.

[0013] Preferably, a liquid inlet is fixedly connected to the top surface of the end cap, and the end of the liquid inlet away from the end cap is connected to the flange of an external feed pump.

[0014] Preferably, the upper half of the crystallization chamber is fixedly connected to a cooling water inlet, the lower half of the crystallization chamber is fixedly connected to a cooling water outlet, and ball valves are fixedly connected to the middle sections of both the cooling water inlet and the cooling water outlet.

[0015] Preferably, a liquid outlet is fixedly connected to the bottom of the crystallization chamber, and a first thermometer is fixedly connected to the middle section of the liquid outlet.

[0016] Preferably, both second thermometers are fixedly connected to the crystallization chamber, and the two second thermometers are respectively set in the upper half and the lower half of the crystallization chamber.

[0017] Preferably, the top fixing plate is fixedly connected to the upper half of the inner wall of the crystallization chamber, the bottom fixing plate is fixedly connected to the lower half of the inner wall of the crystallization chamber, the top fixing plate is located above the cooling water inlet, and the bottom fixing plate is located between the cooling water outlet and the liquid outlet.

[0018] Preferably, the number of cooling pipes is twenty-five, and the two ends of the twenty-five cooling pipes are fixedly connected to the top fixing plate and the bottom fixing plate, respectively.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] I. This application connects the liquid feed inlet to the feed pump, which guides the liquid feed to the crystallization chamber. The liquid feed flows through various cooling pipes. The cooling water inlet is connected to the cooling water pump, and the cooling water outlet is connected to the cooling water tank. During the flow of the liquid feed through the cooling pipes, cooling water is added to the crystallization chamber through the cooling water inlet and discharged through the cooling water outlet. During the flow of the cooling water, the liquid feed in the cooling pipes is cooled by the cooling water carrying away heat. At the same time, crystals precipitate and are discharged into the collection tank at the liquid feed outlet for the next step. This application solves the problem of low crystallization efficiency in existing crystallization equipment by setting up twenty-five cooling pipes for the flow and cooling of the liquid feed.

[0021] Second, during the process of cooling water flowing in the crystallization chamber, heat exchange occurs with the liquid material, causing the temperature of the liquid material to drop. The first thermometer is used to detect the temperature of the liquid material discharged from the outlet. When the liquid material is higher or lower than the preset value, the temperature of the cooling water in the external cooling device can be adjusted. Both second thermometers are used to monitor the temperature of the cooling water to keep the discharged liquid material at the preset value, so that this application has a high crystallization efficiency.
