Description

Technical Field

[0001] The utility model relates to the technical field of crystallization, in particular to a device for balancing the pressure of the cooling water in the jacket of a crystallization tank. Background Art

[0002] A crystallization tank consists of a tank body, a stirring device, a jacket, a heating and cooling system, etc. It is a crystallization device that needs to introduce cooling water or refrigerant water into the jacket of the tank body or the stirring shaft jacket after the material is mixed and reacted. It is widely used in industries such as pharmaceuticals, sugar making, fine chemicals, and bioengineering. Generally, the inlet pipe and outlet pipe of the cooling water of the crystallization tank are connected to the total cooling water pipe to form a set of inlet and outlet water systems. In actual operation, the water pressure of the cooling water is unstable. When the water pressure is too high, it is easy to cause pressure on the jacket of the crystallization tank body and the jacket of the stirring shaft. Seriously, it will cause deformation of the tank wall and the jacket of the stirring shaft, and even form leakage points, resulting in the leakage of cooling water into the crystallization tank body and contacting the material. The impurities such as Ca 2+ , Mg 2+ and acid radical ions in the cooling water will affect the purity and concentration of the crystallization material, reducing the crystallization efficiency and quality. After the tank wall and the stirring shaft of the crystallization tank are deformed, during the operation of the stirring device, it will cause further damage to the equipment, resulting in greater losses. When the water pressure is low, the cooling water flows slowly in the jacket of the crystallization tank body and the jacket of the stirring shaft, and cannot take away the heat inside the crystallization tank in time. And temperature has a great influence on the crystallization efficiency and quality of the material.

[0019] As Figure 1As shown in the figure, a device for balancing the pressure of the cooling water in the jacket of a crystallization tank includes a tank body 1. A jacket 16 is provided on the tank body 1. The lower end of the jacket 16 is provided with a water inlet, and a cooling water inlet pipe 2 is connected at the water inlet. The upper end of the jacket 16 is provided with a water outlet, and a cooling water outlet pipe 3 is connected at the water outlet. An inlet valve 11 is provided on the cooling water inlet pipe 2. The outlet end of the cooling water outlet pipe 3 is connected to a water receiving tank 4. The pressure of the cooling water in the cooling water outlet pipe 3 can be released into the water receiving tank 4. A water outlet pipe 10 is connected to the bottom of the water receiving tank 4. Along the direction of cooling water transportation, a water control valve 17 and a water pump 18 are successively provided at the end of the water outlet pipe 10 away from the water receiving tank 4. A spiral cooling pipe 12 is provided on the outer wall of the tank body 1. The lower end of the cooling pipe 12 is provided with a cooling pipe water inlet 13, and the upper end of the cooling pipe 12 is provided with a cooling pipe water outlet 14. The inlet end of the cooling pipe water inlet 13 extends outward and extends out of the jacket 16. The end of the cooling pipe water inlet 13 extending out of the jacket 16 is connected to the outlet end of the water outlet pipe 10. The outlet end of the cooling pipe water outlet 14 extends outward and extends out of the jacket 16. The end of the cooling pipe water outlet 14 extending out of the jacket 16 is connected to the upper end of the water receiving tank 4 through a pipeline. A circular hole is provided on both the outer side wall of the jacket 16 and one side of the cooling pipe 12 away from the tank body 1. The axes of the two circular holes coincide, and sealing rings are provided on both circular holes. It also includes a waterproof electric push rod 15. One end of the electric push rod 15 is located outside the jacket 16. The other end of the electric push rod 15 extends into the jacket 16 through the sealing ring on the outer side wall of the jacket 16 and is hermetically connected to the sealing ring on the outer side wall of the jacket 16. The end of the electric push rod 15 can extend into the sealing ring on the cooling pipe 12. When the electric push rod 15 is started, the electric push rod 15 can extend into the cooling pipe 12 through the sealing ring on the cooling pipe 12 and be in close contact with the sealing ring on the cooling pipe 12.

[0020] The end of the cooling water inlet pipe 2 away from the jacket 16 is connected to a main water pipe 19. A first filter screen 5 is detachably provided at the top of the water receiving tank 4. The bottom of the side wall of the water receiving tank 4 is communicated with a transparent water level pipe 6. The top of the transparent water level pipe 6 is higher than the top of the water receiving tank 4. A second filter screen 7 is provided at the top of the transparent water level pipe 6. A bracket is provided on the outer side wall of the jacket 16, and the electric push rod 15 is fixed on the bracket. It also includes a recovery pipe 8. A valve is provided on the recovery pipe 8. One end of the recovery pipe 8 is connected to the water outlet pipe 10, and the other end of the recovery pipe 8 is connected to a collection pool 9. The collection pool 9 is located below the water receiving tank 4.

[0021] The utility model is provided with a water receiving tank 4 at the water outlet end of the cooling water outlet pipe 3. The cooling water flowing out of the cooling water outlet pipe 3 directly enters the water receiving tank 4. When the water pressure in the main water pipe 19 is too high, the pressure in the jacket 16 is timely released into the water receiving tank 4, relieving the water pressure in the jacket 16 and avoiding damaging the tank body 1. The water outlet end of the cooling water outlet pipe 5 is higher than the top end of the tank body 1. The cooling water enters from the lower water inlet of the jacket 16, expelling the air in the jacket 16. The cooling water entering the jacket 16 enters the cooling pipe 12 through the sealing ring on the cooling pipe 12, filling the entire jacket 16 and the cooling pipe 12 with cooling water. The cooling pipe 12 is in direct contact with the tank body 1. Therefore, the cooling water in the jacket 16 and the cooling water in the cooling pipe 12 can both exchange heat with the tank body 1 and take away heat, achieving a good cooling effect. The cooling water flows out from the upper water outlet of the jacket 16 and the cooling pipe water outlet 14 into the water receiving tank 4. The water pressure of the cooling water is judged according to the change of the water level in the water receiving tank 4. When the water pressure is low, the electric push rod 15 is started, and the electric push rod 15 is pushed towards the cooling pipe 12 until the end of the electric push rod 12 extends into the cooling pipe 12 and is in close contact with the sealing ring on the cooling pipe 12. After the sealing ring on the cooling pipe 12 is blocked by the electric push rod 12, the water control valve 17 on the water outlet pipe 10 is opened, and the water pump 18 is started. The cooling water in the water receiving tank 4 can enter the cooling pipe 12 and exchange heat with the material in the tank body 1. The volume of the cooling pipe 12 is small and the cooling pipe 12 is in direct contact with the tank body 1. The cooling water can flow quickly in the cooling pipe 12, taking away the heat in the tank body 1 relatively quickly and flowing into the water receiving tank 4 through the cooling pipe water outlet 14. At the same time, the cooling water in the jacket 16 no longer enters the cooling pipe 12, reducing the diversion and also improving the flow of the cooling water in the jacket 16. The two jointly relieve the situation that the cooling water cannot take away the heat in the tank body 1 in time when the water pressure is low. The first filter screen 5 intercepts foreign impurities from the outside, preventing pollution to the cooling water in the water receiving tank 4. The first filter screen 5 can be replaced regularly as needed. The top end of the transparent water level pipe 6 is provided with a second filter screen 7 to prevent foreign impurities from falling into the transparent water level pipe 6. The water level in the water receiving tank 4 is determined by observing the transparent water level pipe 6. When the water level in the water receiving tank 4 is flush with the lower end of the first filter screen 5, the valve on the recovery pipe 8 is opened, allowing the cooling water to flow from the water receiving tank 4 into the collection pool 9 to avoid overflow of the cooling water in the water receiving tank 4.

[0022] The utility model can also be used for the stirring shaft jacket. When the water pressure is high, the water pressure of the cooling water in the stirring shaft jacket is released into the water receiving tank 4 to prevent damage to the stirring shaft jacket. When the water pressure is low, the cooling water in the water receiving tank 4 enters the cooling pipe 12 and exchanges heat with the material in the tank body 1, relieving the situation that the cooling water cannot take away the heat in the tank body 1 in time when the water pressure is low.

[0023] Specific operation process

[0024] When the materials in the tank body 1 are mixed for crystallization, the water inlet valve 11 on the cooling water inlet pipe 2 is opened. Cooling water flows from the main water pipe 19 into the cooling water inlet pipe 2 and enters the jacket 16. When the cooling water flows through the sealing ring on the cooling pipe 12, it enters the cooling pipe 12. The cooling water discharges the air in the jacket 16 and the cooling pipe 12 and fills the entire jacket 16 and the cooling pipe 12. Then, the cooling water flows out from the cooling water outlet pipe 3 connected to the outlet of the tank body 1 and the cooling pipe outlet 14 respectively, enters the water receiving tank 4, takes away the heat in the tank body 1, and enables the materials in the crystallization tank to cool down and crystallize. The water level in the water receiving tank 4 and the height of the cooling water pressure are determined through the transparent water level pipe 6. When the cooling water pressure is relatively high, the pressure of the cooling water is released into the water receiving tank 4 to avoid damage to the tank body 1. When the cooling water pressure is relatively low, the electric push rod 15 is started. The end of the electric push rod 15 pushes towards the cooling pipe 12 until the end of the electric push rod 15 extends into the cooling pipe 12 and is in close contact with the sealing ring on the cooling pipe 12. At this time, the cooling water in the jacket 16 no longer enters the cooling pipe 12, and the flow rate of the cooling water in the jacket 16 increases. The electric push rod 15 is shut down. Then, the water control valve 17 on the outlet pipe 10 is opened, and the water pump 18 is started. The cooling water in the water receiving tank 4 flows into the outlet pipe 10 and enters the cooling pipe 12 from the cooling pipe water inlet 13. The jacket 16 and the cooling pipe 12 jointly take away the heat in the tank body 1, relieve the situation that the heat cannot be taken away in time due to the low water pressure in the main water pipe, and reduce the impact on the crystallization rate and quality. When the cooling water pressure becomes higher, the water pump 18 and the water control valve 17 on the outlet pipe 10 are closed, and the electric push rod 15 is started. The end of the electric push rod 15 pushes away from the cooling pipe 12. The end of the electric push rod 15 leaves the sealing ring of the cooling pipe 12. Then, the electric push rod 15 is shut down. The cooling water in the jacket 16 continues to enter the cooling pipe 12 to take away the heat in the tank body 1. When the water level in the water receiving tank 4 is flush with the lower end of the first filter screen 5, the valve on the recovery pipe 8 is opened to enable a part of the cooling water in the water receiving tank 4 to flow into the collection pool 9. Then, the valve on the recovery pipe 8 is closed.
