Description

Technical Field

[0001] This utility model belongs to the technical field of homogenizer water cooling system, and relates to a cooling water supply control system for homogenizers. Background Technology

[0002] In food processing, a homogenizer is used to break down liquid materials into smaller particles through a combination of compression, strong impact, and depressurization expansion. This allows the materials to mix more evenly. For example, in dairy processing, a homogenizer breaks down the fat in milk into smaller pieces, resulting in a more stable product system and a whiter appearance.

[0003] Because the homogenizer generates a significant amount of heat during operation due to the reciprocating motion of the plunger rod and the high temperature of the lubricating oil in the crankcase, a water-cooling system is required to cool the plunger seals and crankcase lubricating oil during homogenization to achieve better working efficiency. When using the homogenizer, the water-cooling system is connected, and cooling water flows through the homogenizer, providing a cooling effect. Since the cooling water flowing through the homogenizer is heated, a circulation system is implemented to allow the cooling water to circulate repeatedly, enabling it to be reused. However, as the homogenizer operates for an extended period, the cooling water temperature rises and becomes insufficient to cool the homogenizer. At this point, the cooling water needs to be replaced to maintain cooling effectiveness, but this results in frequent cooling water replacements, leading to resource waste. Utility Model Content

[0004] The purpose of this invention is to provide a cooling water supply control system for a homogenizer, so as to improve the problem that the cooling water used in the homogenizer cannot cool the homogenizer after being heated, and to increase the number of cooling water circulation cycles.

The first liquid level sensor 5 and the second liquid level sensor 6 are used to detect the high and low water levels of the first water tank 1, respectively.

[0015] The outlet of the first cooling pipe 8 is connected to the inlet of the heat exchanger 2. A first solenoid valve 12 is installed on the first cooling pipe 8. The outlet of the heat exchanger 2 is connected to the inlet of the drainage tank 3, and a first flow switch 13 is installed on the pipe connecting the outlet of the heat exchanger 2 and the inlet of the drainage tank 3. The cooling outlet of the heat exchanger 2 is connected to the inlet of the crankcase cooling system 14, and the cooling inlet of the heat exchanger 2 is connected to the outlet of the crankcase cooling system 14. The cooling outlet and cooling inlet of the heat exchanger 2 are connected inside the heat exchanger 2, and the outlet and inlet of the heat exchanger 2 are connected inside the heat exchanger 2. The crankcase cooling system 14 can be a cooling circulation pipe installed on the surface of the crankcase.

[0016] The outlet of the second cooling pipe 9 is connected to the inlet of the plunger cooling system 15 with plunger seal. The second cooling pipe 9 is equipped with a second solenoid valve 16 and a second flow switch 17. The outlet of the plunger cooling system 15 with plunger seal is connected to the inlet of the drainage tank 3. The plunger cooling system 15 can be a circulating pipe arranged annularly on the outer surface of the plunger seal. By setting the first flow switch 13 and the second flow switch 17, pipe abnormalities can be monitored in real time.

[0017] The outlet of the drainage tank 3 is connected to the inlet of the intermediate cooling water tank 4 via an outlet pipe 18. A second circulating water pump 19 and a filter 20 are installed on the outlet pipe 18. The outlet of the intermediate cooling water tank 4 is connected to the first inlet pipe 22 of the first water tank 1 via a return pipe 21. The first inlet pipe 22 is also connected to the inlet of the first water tank 1. A third circulating water pump 23 is installed on the return pipe 21, and a second electric valve 24 is installed on the first inlet pipe 22. The filter 20 prevents clogging by impurities and improves system reliability.

[0018] The intermediate cooling water tank 4 is also equipped with a water replenishment inlet, which is connected to a water replenishment pipe. The water replenishment pipe is equipped with a liquid replenishment valve 25. The water replenishment pipe is connected to an external water source. When water needs to be replenished, the liquid replenishment valve 25 can be opened through the PLC controller to replenish water.

[0019] The first liquid level sensor 5, the second liquid level sensor 6, the first electric valve 10, the first circulating water pump 11, the first solenoid valve 12, the first flow switch 13, the second solenoid valve 16, the second flow switch 17, the filter 20, the second circulating water pump 19, the third circulating water pump 23, the second electric valve 24, and the replenishing valve 25 are electrically connected to the PLC controller.

[0020] The usage process of this embodiment is as follows: the PLC controller opens the first liquid level sensor 5, the second liquid level sensor 6, the first electric valve 10, the first circulating water pump 11, the first solenoid valve 12, the first flow switch 13, the second solenoid valve 16, the second flow switch 17, the filter 20, and the second circulating water pump 19, so that the cooling water supply control system for the homogenizer can cool the crankcase and plunger seal of the homogenizer.

[0021] Cooling water in the first water tank 1 enters the first cooling pipe 8 and the second cooling pipe 9 via the first circulating water pump 11. Cooling water in the first cooling pipe 8 enters the heat exchanger 2 and exchanges heat with the crankcase cooling system 14, then outputs heated water into the drainage pool 3. Cooling water in the first cooling pipe 8 enters the plunger cooling system 15 to exchange heat with the plunger seal, then outputs heated water into the drainage pool 3. Water in the drainage pool 3 is filtered by the filter 20 and then pumped to the intermediate cooling water tank 4 by the second circulating water pump 19 for cooling. When the second liquid level sensor 6 detects that the water level in the first water tank 1 is lower than the set value, the PLC controller opens the third circulating water pump 23 and the second electric valve 24. The third circulating water pump 23 pumps cooling water from the intermediate cooling water tank 4 to the first water tank 1. When the first liquid level sensor 5 detects that the water level in the first water tank 1 is higher than the set value, the PLC controller closes the third circulating water pump 23 and the second electric valve 24, thus achieving cooling water circulation.

[0022] Example 2: A cooling water supply control system for a homogenizer like Figure 2 As shown, this embodiment is a cooling water supply control system for a homogenizer. The difference from embodiment 1 is that this embodiment also includes a second water tank 26. A third liquid level sensor 27 is provided above the inner surface of the side wall of the second water tank 26, and a fourth liquid level sensor 28 is provided below the inner surface of the side wall. The third liquid level sensor 27 and the fourth liquid level sensor 28 are used to detect the high and low water levels of the second water tank 26, respectively.

[0023] The outlet of the second water tank 26 is connected to the inlet of the first cooling pipe 8 and the second cooling pipe 9 through the second outlet pipe 29. The second outlet pipe 29 is equipped with a third electric valve 30 and a fourth circulating water pump 31. The inlet of the second water tank 26 is connected to the outlet of the return water pipe 21 of the intermediate cooling water tank 4 through the second inlet pipe 32. The second inlet pipe 32 is equipped with a fourth electric valve 33.

[0024] The third liquid level sensor 27, the fourth liquid level sensor 28, the third electric valve 30, the fourth circulating water pump 31, and the fourth electric valve 33 are electrically connected to the PLC controller.

[0025] In this embodiment, when the second liquid level sensor 6 detects that the water level in the first water tank 1 is lower than the set value, the PLC controller can open the third electric valve 30 and the fourth circulating water pump 31 on the second water outlet pipe 29 to supply cooling water, and close the first electric valve 10 and the first circulating water pump 11 on the first water outlet pipe 7. Then, the third circulating water pump 23 and the second electric valve 24 are opened, and the cooling water in the intermediate cooling water tank 4 is transported to the first water tank 1 through the third circulating water pump 23. When the fourth liquid level sensor 28 detects that the water level in the second water tank 26 is lower than the set value, the PLC control system switches the second water tank 26 and the first water tank 1 again. The PLC control system repeats the switching process according to the water level.
