[0003] The temperature of the water in the water tank continues to rise after contacting the high-temperature material strips, and the cooling effect becomes worse and worse. The existing water tanks all use a water pump to suck the water in the water tank from one end into the plate heat exchanger, and then return to the water tank from the other end after cooling down, thereby cooling the water in the entire water tank. During use, the plate heat exchanger needs to be maintained and cleaned frequently, otherwise the cooling effect will be greatly affected.

For ordinary technicians in this field, the specific meanings of the above-mentioned in this application can be understood according to the specific circumstances.

[0035] like Figure 1 , 2 As shown, a strip cooling water tank in an embodiment of the present application comprises a water tank body 1 and a cooling water jacket 2 wrapped around the outside of the water tank body 1, and a cold flow space 3 is formed between the cooling water jacket 2 and the outside of the water tank body 1;

[0036] The cooling water jacket 2 is provided with a cooling water inlet 21 and a cooling water outlet 22 for connecting to the cooling water system, and the cooling water inlet 21 and the cooling water outlet 22 are in communication with the cold flow space 3;

[0037] The water tank body 1 is further connected to a circulation member 11 for circulating the water in the water tank body 1 .

[0038] In this embodiment, a cooling water jacket 2 is wrapped around the outside of the water tank body 1, and the inner side of the cooling water jacket 2 is closed with the outer side of the water tank body 1 to form a cold flow space 3, and a cooling water inlet 21 and a cooling water outlet 22 connected to the cold flow space 3 are also provided in the cooling water jacket 2, and the cooling water inlet 21 and the cooling water outlet 22 are also connected to the cooling water system at the same time, and the cooling water system is used to provide sufficient and flowing cooling water for the cold flow space 3, and the cooling water enters the cold flow space 3 from the cooling water inlet 21, and is discharged from the cooling water outlet 22 after filling the cold flow space 3, and the cooling water inlet 21 and the cooling water outlet 22 are kept open during operation, so that the cooling water inside the cold flow space 3 can keep circulating, increase the efficiency of heat exchange, and cool the water in the water tank body 1 more efficiently, and the valve opening of the cooling water inlet 21 and the cooling water outlet 22 can also be adjusted according to the temperature to make the cooling effect more stable.

[0039] The water tank body 1 is also connected to a circulation part 11, which is connected to the inside of the water tank body 1 and is used to circulate the water in the water tank body 1 to improve the heat exchange efficiency inside the water tank body 1. When the plastic strips in a high-temperature molten state fall into the water tank body 1, they come into contact with the water inside the water tank body 1 and are quickly cooled and shaped. At this time, the water inside the water tank body 1 is heated up, and the cooling water in the cold flow space 3 does not directly contact the water inside the water tank body 1 for heat exchange, but exchanges heat across the water tank body 1 to cool the water inside the water tank body 1, thereby achieving the effect of cooling the water inside the water tank without using a plate heat exchanger, effectively reducing the processing cost of the water tank.

[0040] In one embodiment, the circulation member 11 is a water circulation pump, which can extract water from the water tank, so that the water in the water tank flows and circulates, facilitating heat exchange.

[0041] like Figure 1 , 2 As shown, in one of the embodiments, a drainage valve 23 is provided at the bottom of the cooling water jacket 2 , and the drainage valve 23 is connected to the cold flow space 3 .

[0042] In this embodiment, a drainage valve 23 connected to the cold flow space 3 is also provided at the bottom of the cooling water jacket 2. Before the operation is performed, the drainage valve 23 can be opened to discharge the residual liquid inside the cold flow space 3. After the drainage is completed, the drainage valve 23 is closed, and then new cooling water is introduced through the cooling water inlet 21.

[0043] like Figure 1 As shown, in one of the embodiments, an exhaust valve 24 is provided on the cooling water outlet 22 .

[0044] In this embodiment, the cooling water outlet 22 is connected to the cold flow space 3, and extends outward through the cooling water jacket 2. An exhaust diversion valve 24 is provided above the cooling water outlet 22. The exhaust diversion valve 24 is used to exhaust the gas inside the cold flow space 3. Before operation, it is necessary to open the cooling water inlet 21 and close the cooling water outlet 22, and keep the exhaust diversion valve 24 open. After the cooling water fills the entire cold flow space 3, the exhaust diversion valve 24 will continue to discharge a stable amount of cooling water. At this time, the exhaust diversion valve 24 can be closed and the cooling water outlet 22 can be opened, so that the cooling water inside the cold flow space 3 can be successfully circulated.

[0045] like Figure 1 As shown, in one preferred embodiment, the cooling water inlet 21 and the cooling water outlet 22 are respectively arranged at two ends of the cooling water jacket 2 in the length direction.

[0046] In this preferred embodiment, the cooling water jacket 2 is divided into two ends in the length direction, and the cooling water inlet 21 and the cooling water outlet 22 are respectively arranged at the two ends, which can increase the heat exchange range between the cooling water in the cold flow space 3 and the water inside the water tank body 1, thereby increasing the efficiency of heat exchange and preventing the cooling water from cooling only a partial area inside the water tank body 1.

[0047] In one embodiment, the two ends of the circulation member 11 are respectively connected with a circulation outlet pipe 12 and a circulation inlet pipe 13 , and the circulation outlet pipe 12 and the circulation inlet pipe 13 penetrate the cooling water jacket 2 and are respectively connected with the interior of the water tank body 1 .

[0048] In this embodiment, the interior of the water tank body 1 is connected with a circulation outlet pipe 12 and a circulation inlet pipe 13. One end of the circulation part 11 is connected to the circulation inlet pipe 13, and the other end is connected to the circulation outlet pipe 12. The circulation part 11 is used to circulate the water inside the water tank body 1, so that the heat exchange efficiency is higher.

[0049] The circulation outlet pipe 12 and the circulation inlet pipe 13 respectively penetrate the cooling water jacket 2 and communicate with the interior of the water tank body 1. The water extracted by the circulation member 11 does not directly interact with the cooling water in the cold flow space 3, but performs heat exchange across the outside of the water tank body 1.

[0050] like Figure 1 As shown, in a preferred embodiment, the circulation outlet pipe 12 is installed at the end where the cooling water inlet 21 is located and is connected to one end of the water tank body 1, and the circulation inlet pipe 13 is installed at the end where the cooling water outlet 22 is located and is connected to the other end of the water tank body 1.

[0051] In this preferred embodiment, the water inside the water tank body 1 flows from the circulation inlet pipe 13 to the circulation outlet pipe 12 and is then pumped away by the circulation component 11. The cooling water inside the cold flow space 3 flows from the cooling water inlet 21 to the cooling water outlet 22. The flow direction of the water inside the water tank body 1 is opposite to the flow direction of the cooling water inside the cold flow space 3, forming a convective heat exchange. The heat exchange efficiency between the water inside the water tank body 1 and the cooling water inside the cold flow space 3 is higher.

[0052] like Figure 1 As shown, in one of the embodiments, at least two baffles 25 for changing the direction of water flow are installed on the side of the cooling water jacket 2 facing the water tank body 1.

[0053] In this embodiment, the baffle 25 can be welded on the side of the cooling water jacket 2 facing the water tank body 1. When the cooling water flows into the cold flow space 3 from the cooling water inlet 21, part of the water flow may not flow through the entire cold flow space 3 and flow out from the cooling water outlet 22. The baffle 25 allows the cooling water in the cold flow space 3 to flow through every corner of the cold flow space 3, making the internal temperature of the cold flow space 3 more uniform and stable, and can provide a more uniform cooling effect for the water inside the water tank body 1.

[0054] like Figure 1 As shown, in one embodiment, the cooling water jacket 2 includes a bottom plate 26 and side plates 27 connected to both sides of the bottom plate 26, and the two side plates 27 are arranged opposite to each other;

[0055] Each baffle 25 is connected to one of the side plates 27, and the baffles 25 are staggered in the length direction of the cooling water jacket 2;

[0056] The baffle 25 includes a first plate 251 and a second plate 252 connected at an angle. The first plate 251 is connected to the bottom plate 26 , and the second plate 252 is connected to one of the side plates 27 .

[0057] In this embodiment, the cross-section of the water tank body 1 is U-shaped, and the cooling water jacket 2 wraps the outer side of the entire water tank body 1. The cooling water jacket 2 includes a bottom plate 26 and side plates 27 connected to both sides of the bottom plate 26. The baffle 25 includes a first plate 251 connected to the bottom plate 26 and a second plate 252 connected to one of the side plates 27. The baffles 25 are staggered in the length direction of the cooling water jacket 2. When viewed from the length direction of the cooling water jacket 2, the second plate of the first baffle 25 is located on the side plate 27 on the right, the second plate 252 of the second baffle 25 is located on the side plate 27 on the left, and the second plate 252 of the third baffle 25 is located on the side plate 27 on the right. The three baffles 25 are staggered.

[0058] When the cooling water flows in the cold flow space 3, the second plate 252 of the baffle 25 will guide part of the cooling water on the side plate 27 to flow to the first plate 251, and the first plate 251 of the baffle 25 will guide part of the cooling water to flow to the other side plate 27, so that the cooling water in the cold flow space 3 can flow through every corner of the cold flow space 3 without dead corners, thereby increasing the heat exchange range between the cooling water inside the cold flow space 3 and the water inside the water tank body 1, thereby improving its heat exchange efficiency.

[0059] like Figure 1 , 2 As shown, in another preferred embodiment, the strip cooling water tank further includes a heat preservation jacket 4 wrapping the outside of the cooling water jacket 2, and a heat preservation space is formed between the heat preservation jacket 4 and the outside of the cooling water jacket 2;

[0060] The insulation space is filled with insulation medium.

[0061] In this preferred embodiment, the outer side of the cooling water jacket 2 in the strip cooling water trough is also wrapped with an insulation jacket 4, and the insulation jacket 4 forms an insulation space with the outer side of the cooling water jacket 2 on the side facing the cooling water jacket 2, wherein the insulation space is filled with an insulation medium. The insulation space can reduce the temperature contact between the cold flow space 3 and the outside, thereby reducing the loss of cold, and can also avoid the formation of condensate on the surface of the trough due to temperature difference, thereby solving the problem of slippery construction sites, saving energy and improving the working environment.

[0062] The heat-insulating medium may be a heat-insulating foam or other heat-insulating material such as rubber-plastic sponge, or the inside of the heat-insulating space may be evacuated to make the heat-insulating space a vacuum space.

[0063] like Figure 1 As shown, in one of the embodiments, a sink bracket 5 for movement is further provided below the sink body 1 , and a circulation member 11 is installed on the sink bracket 5 .

[0064] In this embodiment, a sink bracket 5 is provided below the sink body 1, and the circulation component 11 is installed on the sink bracket 5. The connecting pipe between the circulation outlet pipe 12 and the circulation component 11, and the connecting pipe between the circulation inlet pipe 13 and the circulation component 11 are both mounted on the sink bracket 5 to prevent falling off.

[0065] The water tank support 5 has at least four wheels, each of which is provided with a locking member, which is used to fix each wheel to prevent the water tank support 5 from moving when no one is watching.

[0066] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0067] like Figure 1 , 2 As shown, in a preferred embodiment, the strip cooling water trough includes a trough body 1 and a cooling water jacket 2 wrapped around the outside of the trough body 1. The bottom of the trough body 1 is wavy, with a peak-to-valley height difference of 30-50mm and a peak-to-valley stroke of 50mm. A cold flow space 3 is formed between the inner side of the cooling water jacket 2 and the outer side of the trough body 1. The cold flow space 3 is spaced 30mm apart. A cooling water inlet 21 and a cooling water outlet 22 connected to the cold flow space 3 are also provided in the cooling water jacket 2. The cooling water inlet 21 and the cooling water outlet 22 are also simultaneously connected to a cooling water system for providing cooling water to the cold flow space 3. The cooling water enters the cold flow space 3 from the cooling water inlet 21 and flows out of the cold flow space 3 from the cooling water outlet 22. The trough body 1 is also connected to a circulation part 11 for circulating the water in the trough body 1. The circulation part 11 can be a water circulation pump. The cooling water flowing in the cold flow space 3 can cool the water in the trough body 1. There is no need to use a heat exchanger, thereby reducing the manufacturing cost of the trough and the maintenance cost during use.

[0068] A drainage valve 23 is also provided at the bottom of the cooling water jacket 2, which can drain the liquid remaining in the cold flow space 3; an exhaust valve 24 is provided on the cooling water outlet 22, and three baffles 25 are installed on one side of the cooling water jacket 2 facing the water tank body 1. The baffles 25 are staggered in the length direction of the cooling water jacket 2, and the first plate 251 of the baffle 25 is connected to the bottom plate 26 of the cooling water jacket 2, and the second plate 252 of the baffle 25 is connected to the side plate 27 of the cooling water jacket 2.

[0069] When operation is required, fill the water tank body 1 with water, exhaust the circulation part 11 and start it to circulate the water inside the water tank body 1; confirm that the drain guide valve 23 is in the closed state, open the cooling water inlet 21 and the exhaust guide valve 24, close the cooling water outlet 22, let the cooling water enter the cold flow space 3, and then with the help of the baffle 25, the cooling water will flow through every corner of the cold flow space 3 without dead corners, and after the exhaust guide valve 24 has a continuous and stable water discharge, the exhaust guide valve 24 can be closed, and the cooling water outlet 22 can be opened, so that the cooling water in the cold flow space 3 can be successfully circulated, and the valve opening can also be adjusted according to the temperature.

[0070] The two ends of the circulation member 11 are also connected with a circulation outlet pipe 12 and a circulation inlet pipe 13, respectively, which penetrate the cooling water jacket 2 and are respectively connected to the interior of the water tank body 1; the cooling water inlet 21 and the cooling water outlet 22 are respectively arranged at the two ends of the cooling water jacket 2 in the length direction, the circulation outlet pipe 12 is installed at the end where the cooling water inlet 21 is located, and the circulation inlet pipe 13 is installed at the end where the cooling water outlet 22 is located; the flow direction of the cooling water in the cold flow space 3 is opposite to the flow direction of the water inside the water tank body 1, thereby forming a convective heat exchange, so that the heat exchange efficiency is higher, and the cooling effect of the cooling water on the water inside the water tank body 1 is better.

[0071] The outside of the cooling water jacket 2 is also wrapped with an insulation jacket 4, and an insulation space is formed between the side of the insulation jacket 4 facing the cooling water jacket 2 and the outside of the cooling water jacket 2. The insulation space is filled with insulation foam or rubber and plastic sponge or other insulation materials, which effectively reduces the loss of cold flow space 3, reduces energy consumption, and solves the problem of condensate dripping on the surface of the water tank causing a slippery working environment.
