Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a crystallization unit for crystallization treatment. Background Technology

[0002] During industrial production and wastewater treatment, a large amount of highly concentrated brine is generated. This type of wastewater typically contains more than 5% salt, and in some industrial settings, it can reach 10%-25%. It contains various ions such as Na⁺, Cl⁻, and SO₄²⁻. Because its salinity is much higher than that of ordinary wastewater, direct discharge will seriously damage soil structure, pollute the aquatic environment, and cause irreversible damage to the ecosystem. Therefore, it is necessary to reduce the salinity through specialized treatment technologies or to achieve salt resource recycling and reuse in order to meet environmental emission requirements and resource utilization standards.

[0003] Currently, heated crystallization equipment is commonly used for treating high-concentration brine. Its core principle is to evaporate the water in the brine by heating, thereby causing the salt to crystallize and precipitate. However, in actual operation, the precipitated salt crystals tend to adhere to the surface of the heating equipment, and as the operating time accumulates, they gradually form a scale layer. The scale layer will significantly reduce the heat transfer efficiency of the heating equipment, which will not only affect the crystallization effect and rate, but also increase energy consumption. It may even cause equipment failure due to scale accumulation, thus restricting the efficiency and stability of high-concentration brine treatment. Utility Model Content

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Please see Figure 1-3 This utility model provides a technical solution: a crystallization unit for crystallization treatment, including a water tank 1, four support legs fixedly installed at the bottom of the water tank 1, an evaporation tank 2 fixedly installed on the front outer wall of the water tank 1, an inclined discharge port 3 at the bottom of the evaporation tank 2, electric heating plates 4 fixedly installed on the front and rear inner walls of the discharge port 3, an exhaust pipe 5 fixedly installed on the top of the electric heating plate 4, and water inlet pipes 6 fixedly installed on the front side of the water tank 1 and the rear side of the evaporation tank 2. It also includes an automatic feeding component installed inside the evaporation tank 2 for automatically feeding material into the evaporation tank 2, a pushing component installed on the evaporation tank 2 and the discharge port 3 for discharging crystallized salt, and a cleaning component installed on the surface of the electric heating plate 4 for cleaning the surface of the electric heating plate 4.

[0017] Furthermore, the automatic water replenishment component includes a fixing rod 7, a bending plate 8, a float 9, and a sealing plug 10. The fixing rod 7 is fixedly installed on the inner walls of both sides of the evaporator 2. The bending plate 8 is rotatably installed on the outer wall of the fixing rod 7. The float 9 is fixedly installed on the front side of the bending plate 8. The sealing plug 10 is fixedly installed on the rear side of the bending plate 8, and the sealing plug 10 is in contact with one end of the water inlet pipe 6. When the brine inside the evaporator 2 rises, the brine pushes the float 9 to rise. The float 9 will drive the bending plate 8 and the sealing plug 10 to rotate backward. The sealing plug 10 seals one end of the water inlet pipe 6, automatically stopping the water supply. Conversely, when the high-concentration brine inside the evaporator 2 falls, the sealing plug 10 will separate from the water inlet pipe 6, realizing automatic water replenishment inside the evaporator 2. Automatic water replenishment and water stoppage can be completed without manual operation, ensuring continuous and stable processing.

[0018] Furthermore, the feeding assembly includes a motor A11, a rotating rod 12, and a spiral pusher 13. The motor A11 is fixedly installed on the outer wall of one side of the discharge port 3, the rotating rod 12 is rotatably installed on the inner wall of one side of the discharge port 3, and the spiral pusher 13 is fixedly installed on the outer wall of the rotating rod 12. The output shaft of the motor A11 passes through one side of the discharge port 3 and is fixedly installed at one end of the rotating rod 12. When the motor A11 is started, the motor A11 drives the rotating rod 12 and the spiral pusher 13 to rotate. The spiral pusher 13 can push the crystallized salt falling into the bottom of the evaporator 2, drive the crystallized salt to be discharged from the discharge port 3, and prevent the crystallized salt from accumulating.

[0019] Furthermore, the cleaning components include a salt scraper 14, a movable rod 15, a shaft plate 16, an eccentric shaft 17, and a motor B18. The salt scraper 14 is located inside the evaporator 2. The movable rod 15 is slidably mounted on the top of the evaporator 2, and the bottom end of the movable rod 15 is fixedly mounted to the top of the salt scraper 14. Two shaft plates 16 are fixedly mounted on the front outer wall of the water tank 1. The eccentric shaft 17 is rotatably mounted on the two shaft plates 16. The motor B18 is fixedly mounted on one side of the shaft plate 16. The output shaft of the motor B18 is fixedly mounted to one end of the eccentric shaft 17. When the motor B18 is started, the output shaft of the motor B18 drives the eccentric shaft 17 to rotate. The rotation of the eccentric shaft 17 drives the movable rod 15 and the salt scraper 14 to move up and down reciprocally, so that the salt scraper 14 scrapes away the crystalline salt scale attached to the surface of the electric heating plate in real time, avoiding the accumulation of scale and reducing heat transfer efficiency. This not only improves the crystallization rate and treatment effect, but also reduces the risk of equipment failure.

[0020] Furthermore, one end of the exhaust pipe 5 passes through the front and rear sides of the water tank 1, and the exhaust pipe 5 is spirally arranged inside the water tank 1.

[0021] Furthermore, the movable rod 15 has a movable groove, and the eccentric shaft 17 is movably installed in the movable groove.

[0022] Furthermore, the salt scraper 14 is located between the two electric heating plates 4, and the salt scraper 14 is in contact with the surface of the electric heating plates 4.

[0023] Working principle: High-concentration brine is added to the water tank 1 and enters the evaporator 2 through the inlet pipe 6. When the brine rises inside the evaporator 2, it pushes the float 9 upward. The float 9 drives the bending plate 8 and the sealing plug 10 to rotate backward, sealing one end of the inlet pipe 6 and automatically stopping the water flow. Conversely, when the high-concentration brine falls inside the evaporator 2, the sealing plug 10 separates from the inlet pipe 6, automatically adding water to the evaporator 2. The electric heating plate 4 is activated to heat the high-concentration brine, causing it to evaporate and precipitate crystals. The motor A11 is then activated, driving the rotating rod 12 and the spiral... The rotating push plate 13 pushes the crystallized salt falling into the bottom of the evaporator 2, causing it to be discharged from the outlet 3. The evaporated steam is discharged through the exhaust pipe 5. When the steam enters the exhaust pipe 5, the heat in the steam is transferred to the high-concentration brine inside the water tank 1 through the exhaust pipe 5 to preheat the high-concentration brine and reduce energy consumption. By starting the motor B18, the output shaft of the motor B18 drives the eccentric shaft 17 to rotate. The rotation of the eccentric shaft 17 drives the movable rod 15 and the salt scraper 14 to move up and down repeatedly, so that the salt scraper 14 can clean the crystallized salt formed on the surface of the electric heating plate 4 and prevent the crystallized salt from affecting the heat transfer.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
