[0016] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0018] like Figure 1 As shown, a flow diversion device for a large-volume concrete refrigeration unit includes: a water storage tank 1, a water outlet pipe 2, and a flow diversion pipe 3. The water storage tank 1 includes an iron pipe 4, and the two ends of the iron pipe 4 are welded and sealed with two steel plates 5. The side wall of the iron pipe 4 is connected to the six flow diversion pipes 3. The six flow diversion pipes 3 are evenly arranged in two opposite rows. The flow diversion pipes 3 in the same row are arranged at a fixed interval in the length direction. The two rows of flow diversion pipes 3 are staggered in the length direction, and one of the steel plates 5 is connected to the water outlet pipe 2. The device presents a barrel-shaped overall structure. The existence of the water storage tank 1 is not only to store cooling water, but also to uniformly allocate each flow diversion pipe 3.

[0019] The iron pipe 4 has a length of 1 m and a diameter of 0.5 m, and the steel plate 5 has a thickness of 6 mm. The structure is not only strong and airtight, but also can withstand pressure.

[0020] The interval between the guide pipes 3 in the same row in the length direction is 0.3m, and the interval between the guide pipes 3 on the opposite side in the length direction is 0.15m. This staggered arrangement maximizes the use of the limited space between the guide pipes 3. Under such a design, remotely controlled devices can be properly placed to achieve remote control of flow. By controlling different combinations of guide pipes 3, different coverage areas can be formed, providing the possibility for a diverse working environment.

[0021] The outlet of the guide pipe 3 is provided with a joint 6. By flexibly using the joint 6, it can be conveniently connected with various equipment to meet the needs of different casting warehouse surfaces.

[0022] It also includes: a refrigeration unit 7 and a variable frequency water pump 8. The variable frequency water pump 8 is provided inside the refrigeration unit 7, and the outlet of the variable frequency water pump 8 is connected to the water outlet pipe 2. The refrigeration unit 7 is passed with water to cool the cooling water, and the variable frequency water pump 8 transports the cooling water through the water outlet pipe 2 and stores it in the water storage tank 1.

[0023] The water storage tank 1 is equipped with a water level gauge 9 and a pressure sensor 10, which are both data-connected to the first controller 11. The first controller 11 controls the power and switch of the variable frequency water pump 8. The first controller 11 is a PLC controller. The water level gauge 9 and the pressure sensor 10 transmit the values ​​to the first controller 11 in real time. The first controller 11 compares the warning value. When the water level does not meet the water flow of the guide pipe 3 or the water pressure inside the water storage tank 1 is too high, the first controller 11 will control the variable frequency water pump 8 to adjust the power or stop the variable frequency water pump 8 from supplying water to form a safety protection mechanism to ensure safety and reliability during use.

[0024] The guide pipe 3 is provided with an electromagnetic flow valve 12,7, which is electrically connected to a second controller 13. The second controller 13 is a PLC controller, which controls the flow rate of each chamber respectively to adapt to the temperature change inside the large volume concrete.

[0025] The PLC controller used by the first controller 11 and the second controller 13 may be Siemens S7-200.

[0026] The outer side of the water storage tank 1 is covered with a heat preservation blanket to avoid the temperature loss of cooling water during the transportation process.

[0027] The inner side of the water storage tank 1 is coated with anti-corrosion paint to prevent the cooling water from corroding the equipment, making it have good corrosion resistance.

[0028] In summary, when the refrigeration unit 7 is connected to water, the utility model enables the cooling water from a single outlet to be used by multiple warehouses, and controls the temperature difference between the inside and outside of the concrete on the multiple warehouse surfaces after pouring. In operation, each individual guide pipe 3 can cover a range of 100 meters. By flexibly using the joint 6, it can be easily connected to various equipment to meet the needs of different pouring warehouse surfaces. When all are connected, it can supply cooling water to twelve warehouses within a range of 2,000 square meters. While ensuring the supply of cooling water to multiple warehouses, the flow rate of each warehouse is controlled separately by installing an electromagnetic flow valve 12 on the guide pipe to adapt to the temperature changes inside the large volume of concrete.

[0029] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method.
