Description

Technical Field

[0001] This utility model relates to the field of food production technology, and in particular to a cooling water circulation system for a casting line. Background Technology

[0002] In the chocolate production process, the temperature of the chocolate paste is required to be maintained between 30°C and 32°C when it enters the mold. After the chocolate paste enters the mold through the pouring head, it needs to be cooled down through a cooling channel. The temperature of the cooling channel is generally set at around 5°C. After the chocolate paste has been cooled in the cooling channel for about an hour, it solidifies from a liquid state to a solid state. The solid chocolate is then demolded by flipping the mold, and the finished chocolate is conveyed to an automatic packaging machine for packaging.

[0003] Currently, in this casting system, cooling is achieved using a chiller. The chiller generates heat during operation, requiring cooling of its compressor to maintain its effectiveness. Cooling is achieved through a circulation pipeline connected to a cooling tower. The circulation pipeline circulates low-temperature water from the cooling tower to the chiller, cooling it down. The high-temperature water, having absorbed heat from the chiller, then returns to the cooling tower for further cooling.

[0004] However, during the summer, the temperature is high, causing the cooling tower water temperature to be too high (around 35°C), which cannot meet the cooling requirements of the cooler. As a result, the cooler cannot effectively cool down the water, reducing the cooling effect. Consequently, the temperature of the casting cooling channel is high, and the cast products cannot solidify and be demolded, severely affecting production. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a cooling water circulation system for a casting line to solve the above-mentioned technical problems.

[0006] This utility model provides a cooling water circulation system for a casting line, including a first cooling tower, a chiller unit, and a water tank. The first cooling tower has a first circulation pipeline connected to the chiller unit of the casting line. The water tank is connected to the chiller unit, and the chiller unit is used to cool the water in the water tank. The water tank has a second circulation pipeline connected to the chiller unit of the casting line. Valves are provided on both the first and second circulation pipelines to open or close the first or second circulation pipeline.

[0007] Optionally, the first circulation pipeline includes a first outlet pipeline and a first return pipeline, which are connected to the first cooling tower to form a circulation pipeline. The second circulation pipeline includes a second outlet pipeline and a second return pipeline, which are connected to the water tank to form a circulation pipeline. It also includes a T-connector a, which is connected to both the first outlet pipeline and the second outlet pipeline, and is connected to the cooling machine.

[0008] Optionally, it also includes a three-way pipe b, to which both the first return water pipe and the second return water pipe are connected, and the three-way pipe b is also connected to the cooler.

[0009] Optionally, it also includes a third circulation pipeline, which connects the first cooling tower and the chiller unit to cool the chiller unit.

[0010] Optionally, the third circulation pipeline includes a third outlet pipeline and a third return pipeline, both of which are connected to the first cooling tower and the chiller unit to cool the chiller unit.

[0011] Optionally, it also includes a three-way pipe c, which connects the first water outlet pipe and the third water outlet pipe and then connects to the three-way pipe a.

[0012] Optionally, it also includes a tee pipe d, which connects the first return water pipe, the third return water pipe, and the tee pipe b.

[0013] Optionally, it also includes a fourth circulation pipeline, which includes a fourth outlet pipeline and a fourth return pipeline, both of which are connected to the water tank and the chiller unit.

[0014] Optionally, the water tank is provided with a water inlet for replenishing water into the water tank.

[0015] Optionally, the water tank is equipped with a float to monitor the water level in the tank.

[0016] The beneficial effects of this utility model are as follows: by adding a cooling circulation pipeline to connect the cooling machine of the casting line, the cooling machine is cooled down. When the summer temperature is too high and the water temperature in the first cooling tower is too high to effectively cool the cooling machine, the cooling machine can also be cooled by the water in the water tank cooled by the chiller unit, ensuring that the cooling machine maintains the temperature required for production and ensuring production output.

[0025] like Figure 1 As shown, this embodiment provides a cooling water circulation system for a casting line, including a first cooling tower 10, a second cooling tower 20, a chiller unit 30, and a water tank 40. The first cooling tower 10 has a first circulation pipe 11 connected to the chiller of the white chocolate casting line, and the second cooling tower 20 has a fifth circulation pipe 21 connected to the chiller of the dark chocolate casting line. The two cooling towers are connected to the chillers of the two casting lines through two circulation pipes respectively, to cool the condensers or compressors of the chillers in the two casting lines. In winter, when the outdoor temperature is low, the water temperature in the first cooling tower 10 and the second cooling tower 20 is also low, effectively cooling the chillers. However, in summer, when the outdoor temperature is high, the water temperature in the first cooling tower 10 and the second cooling tower 20 is also high, failing to effectively cool the chillers and affecting production output.

[0026] To address the issue of high summer temperatures preventing the first cooling tower 10 and the second cooling tower 20 from effectively cooling the chillers, in this embodiment, a water tank 40 is connected to a chiller unit 30. The chiller unit 30 is used to cool the water in the water tank 40. The water tank 40 has a second circulation pipe 41 and a sixth circulation pipe 42 that are connected to the chillers of the two pouring lines. Valves 130 are installed on the first circulation pipe 11, the second circulation pipe 41, the fifth circulation pipe 21, and the sixth circulation pipe 42 to open or close the first circulation pipe 11, the second circulation pipe 41, the fifth circulation pipe 21, or the sixth circulation pipe 42.

[0027] When the outdoor temperature is low and the water temperature in the first cooling tower 10 and the second cooling tower 20 is sufficient to cool the coolers, valves 130 on the second circulation pipe 41 and the sixth circulation pipe 42 are closed, and water tank 40 is not supplied with water. Valve 130 on the first circulation pipe 11 of the first cooling tower 10 and the fifth circulation pipe 21 of the second cooling tower 20 is opened, allowing the first cooling tower 10 and the second cooling tower 20 to cool the coolers of the white chocolate casting line and the dark chocolate casting line respectively through the first circulation pipe 11 and the fifth circulation pipe 21. When the outdoor temperature is high and the water temperature in the first cooling tower 10 and the second cooling tower 20 is insufficient to effectively cool the coolers, valve 130 on the first circulation pipe 11 of the first cooling tower 10 and the fifth circulation pipe 21 of the second cooling tower 20 is closed, and the first cooling tower 10 and the second cooling tower 20 are not supplied with water. Open valves 130 of the second circulation pipeline 41 and the sixth circulation pipeline 42, and water is supplied from the water tank 40 to the second circulation pipeline 41 and the sixth circulation pipeline 42 to cool the coolers of the white chocolate casting line and the black chocolate casting line. Since the water in the water tank 40 is cooled by the chiller unit 30, it can also provide low-temperature water to meet the cooling needs of the coolers when the outdoor temperature is high in summer.

[0028] In the cooling water circulation system for the pouring line provided in this embodiment, the cooling machine of the pouring line is cooled by two water supply sources, which can be adapted to both high and low outdoor temperatures. This avoids the problem that when only the first cooling tower 10 and the second cooling tower 20 are used to supply water in summer when the outdoor temperature is high, the cooling machine of the pouring line cannot be effectively cooled.

[0029] Specifically, regarding the specific connection method of the pipeline in the cooling water circulation system of the casting line provided in this embodiment, such as... Figure 1 As shown in the diagram, the arrows indicate the direction of water flow in each pipe.

[0030] For the circulation pipes of the first cooling tower 10 and the second cooling tower 20: The first circulation pipeline 11 includes a first outlet pipeline 111 and a first return pipeline 112, which are connected to the first cooling tower 10 to form a circulation pipeline. When the first cooling tower 10 is supplied with water, the water flows out from the first outlet pipeline 111, passes through the cooler of the white chocolate casting line, and then flows back into the first cooling tower 10 through the first return pipeline 112. The fifth circulation pipeline 21 includes a fifth outlet pipeline 211 and a fifth return pipeline 212, which are connected to the second cooling tower 20 to form a circulation pipeline. When the second cooling tower 20 is supplied with water, the water flows out from the fifth outlet pipeline 211, passes through the cooler of the dark chocolate casting line, and then flows back into the second cooling tower 20 through the fifth return pipeline 212.

[0031] For the circulation pipes of water tank 40: The second circulation pipeline 41 corresponds to the cooler of the white chocolate casting line. The second circulation pipeline 41 includes a second outlet pipeline 411 and a second return pipeline 412. The second outlet pipeline 411 and the second return pipeline 412 are connected to the water tank 40 to form a circulation pipeline. When the water tank 40 cools the cooler of the white chocolate casting line, the water in the water tank 40 is pumped out by the water pump 140, flows out through the second outlet pipeline 411, flows through the cooler of the white chocolate casting line, and then flows back to the water tank 40 through the second return pipeline 412.

[0032] The sixth circulation pipe 42 corresponds to the cooler of the dark chocolate casting line. The sixth circulation pipe 42 includes a sixth outlet pipe 421 and a sixth return pipe 422. The sixth outlet pipe 421 and the sixth return pipe 422 are connected to the water tank 40 to form a circulation pipe. When the water tank 40 cools the cooler of the dark chocolate casting line, the water in the water tank 40 is pumped out by the water pump 140, flows out through the sixth outlet pipe 421, flows through the cooler of the dark chocolate casting line, and then flows back to the water tank 40 through the sixth return pipe 422.

[0033] Meanwhile, to avoid excessive and cluttered piping, this embodiment also includes a tee pipe a70 and a tee pipe b80. The first outlet pipe 111 of the first cooling tower 10 and the second outlet pipe 411 of the water tank 40 are both connected to the tee pipe a70, which is connected to the cooling machine of the white chocolate casting line. That is, regardless of whether the water source is the first cooling tower 10 or the water tank 40, the water flows out from the tee pipe a70, and it is only necessary to connect the cooling machine of the white chocolate casting line and the tee pipe a70 with a water pipe.

[0034] The first return water pipe 112 of the first cooling tower 10 and the second return water pipe 412 of the water tank 40 are both connected to the tee pipe b80, which is also connected to the cooler. That is, the water flowing back from the white chocolate casting line first flows into the tee pipe b80, and then flows back to the first cooling tower 10 or the water tank 40 depending on the opening status of the valves 130 of the first return water pipe 112 and the second return water pipe 412. It is only necessary to connect the cooler of the white chocolate casting line and the tee pipe b80 with a water pipe, without the need to configure two additional pipes to connect to the cooler of the white chocolate casting line separately.

[0035] This embodiment also includes a three-way pipe e90 and a three-way pipe f100. The fifth outlet pipe 211 of the fifth circulation pipe 21 of the second cooling tower 20 and the sixth outlet pipe 421 of the sixth circulation pipe 42 of the water tank 40 are both connected to the three-way pipe e90. The remaining port of the three-way pipe e90 is connected to the cooler of the dark chocolate casting line through a pipe. A valve 130 is configured between the three-way pipe e90 and the water tank 40, and a valve 130 is also configured between the three-way pipe e90 and the second cooling tower 20. In both cases where water is supplied by the water tank 40 and the second cooling tower 20, water flows out through the three-way pipe e90, eliminating the need for two separate pipes connected to the cooler of the dark chocolate casting line. The fifth return water pipe 212 of the fifth circulation pipe 21 of the second cooling tower 20 and the sixth return water pipe 422 of the sixth circulation pipe 42 of the water tank 40 are both connected to the tee pipe f100. The remaining port of the tee pipe f100 is connected to the cooling machine of the black chocolate casting line through a pipe. A valve 130 is installed between the tee pipe f100 and the second cooling tower 20, and a valve 130 is also installed between the tee pipe f100 and the water tank 40. In both cases where water is supplied by the water tank 40 and the second cooling tower 20, water first flows into the tee pipe f100 and then flows into the water tank 40 or the second cooling tower 20.

[0036] Furthermore, similar to a cooling unit, the chiller unit 30 also requires cooling during operation, although its cooling demand is not as high as that of a cooling unit. In summer, the high-temperature water from the first cooling tower 10 can also be used to cool the chiller unit 30. Therefore, to improve the operating efficiency of the chiller unit 30, this embodiment also includes a third circulation pipe 50, which connects the first cooling tower 10 and the chiller unit 30 to cool the chiller unit 30 and improve its operating efficiency.

[0037] Specifically, the third circulation pipeline 50 includes a third outlet pipeline 51 and a third return pipeline 52. Both the third outlet pipeline 51 and the third return pipeline 52 are connected to the first cooling tower 10 and the chiller unit 30 to form a circulation pipeline for cooling the chiller unit 30. Additionally, it includes a three-way pipe c110 and a three-way pipe d120. The three-way pipe c110 connects to the first outlet pipe 111 and the third outlet pipe 51, and then connects to the three-way pipe a70. A valve 130 is provided on the first outlet pipe 111 between the three-way pipe c110 and the three-way pipe a70. A valve 130 is also provided on the third outlet pipe 51. The three-way pipe d120 connects to the first return pipe 112, the third return pipe 52, and the three-way pipe b80. A valve 130 is provided on the third return pipe 52. A valve 130 is also provided on the first return pipe 112 between the three-way pipe b80 and the three-way pipe d120.

[0038] When the first cooling tower 10 is used to cool the chiller unit 30, valve 130 between tee pipes b80 and d120, and valve 130 on the first outlet pipe 111 between tee pipes c110 and a70 are closed. At this time, the first cooling tower 10 cannot supply water to the white chocolate casting line. Valve 130 on the third outlet pipe 51 and the third return pipe 52 are opened. Water from the first cooling tower 10 flows out through the third outlet pipe 51, passes through the chiller unit 30, and then flows back into the first cooling tower 10 through the third return pipe 52, thereby cooling the chiller unit 30 and ensuring its operating efficiency.

[0039] Specifically, regarding the connection between the water tank 40 and the chiller unit 30, this embodiment also includes a fourth circulation pipeline 60. The fourth circulation pipeline 60 includes a fourth outlet pipeline 61 and a fourth return pipeline 62. Both the fourth outlet pipeline 61 and the fourth return pipeline 62 are connected to the water tank 40 and the chiller unit 30 to form a circulation pipeline. Water in the water tank 40 is pumped out by the water pump 140, flows out through the fourth outlet pipeline 61, passes through the chiller unit 30, and is cooled by the chiller unit 30. The water then flows back into the water tank 40 through the fourth return pipeline 62. The water circulates between the water tank 40 and the chiller unit 30 to achieve cooling. Furthermore, to ensure sufficient water in the water tank 40, an inlet is provided on the water tank 40 for replenishing water.

[0040] A float ball is installed inside the water tank 40 to monitor the water level. The float ball can be made of plastic and is connected to one end of a connecting rod, while the other end of the connecting rod is connected to an inlet valve located at the water inlet of the water tank 40. When the water level in the water tank 40 drops, the float ball drops along with the water level, at which point the inlet valve opens to replenish water into the water tank 40. As water is replenished, the water level in the water tank 40 rises, and the float ball rises along with the water level. When it rises to a certain height, the inlet valve closes, stopping the replenishment of water into the water tank 40. This part is a conventional technical means and is not the core improvement of this application, so it will not be described in detail here.

[0041] In summary, the cooling water circulation system for the casting lines provided in this embodiment can cool the coolers of the white and dark chocolate casting lines through the first cooling tower 10 and the second cooling tower 20 when the outdoor temperature is low in winter. In summer, when the outdoor temperature is high, the water in the water tank 40 is cooled by the chiller unit 30, and then the cooled water in the water tank 40 is used to cool the coolers of the white and dark chocolate casting lines, demonstrating high adaptability. Furthermore, when using the chiller unit 30 for cooling water, the water in the first cooling tower 10 can also be used to cool the chiller unit 30, ensuring its operating efficiency. Simultaneously, the design of each circulation pipeline simplifies the pipeline structure.

[0042] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
