Description

Technical Field

[0001] This utility model is a device for reusing cooling water from a hot water tank, belonging to the field of hot water utilization technology. Background Technology

[0002] A reaction vessel is a container that enables physical or chemical reactions. By adding various raw materials into the vessel, a series of heating, evaporation, cooling, and low-to-high-speed mixing functions can be performed on the raw materials according to process requirements. It is widely used in petroleum, chemical, rubber and other fields.

[0003] During the operation of the reactor, a hot water tank is needed to control the reaction temperature inside the reactor. The temperature of the hot water tank needs to be adjusted quickly and frequently. When the hot water tank is heated, the steam pipe needs to be turned on to raise the temperature. When it is cooled, the tap water pipe needs to be turned on to replace the high-temperature water in the hot water tank with a large amount of tap water. In the past, when the hot water tank was cooled, the discharged water flowed directly into the water ditch through the overflow pipe, resulting in a large waste of water resources. Therefore, this application proposes a device for reusing the cooling water of the hot water tank. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for reusing cooling water from a hot water tank.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A device for reusing cooling water from a hot water tank includes a hot water tank and a collection tank. The top of the hot water tank is connected to a steam pipe and a tap water pipe, respectively. An overflow pipe is connected to the upper side of the hot water tank, and a hot water circulation pump is connected to the lower side of the hot water tank. The collection tank is placed below the outlet of the overflow pipe, and a cooling water collection pump is connected to the lower side of the collection tank. The outlet of the cooling water collection pump is connected to a second pipe, and the other end of the second pipe is connected to the main circulating water return pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a device for reusing cooling water from a hot water tank, comprising a hot water tank 10 and a collection tank 5. The top of the hot water tank 10 is connected to a steam pipe 9 and a tap water pipe 8, respectively. An overflow pipe 11 is connected to the upper side of the hot water tank 10, and a hot water circulation pump 12 is connected to the lower side of the hot water tank 10. The collection tank 5 is placed below the outlet of the overflow pipe 11, and a cooling water collection pump 1 is connected to the lower side of the collection tank 5. The outlet of the cooling water collection pump 1 is connected to a second pipe 3, and the other end of the second pipe 3 is connected to... The other end of the circulating water return main pipe 7 is connected to the circulating water return main pipe 7. The hot water tank 10 is cooled down, and the valve on the tap water pipe 8 is opened, allowing a large amount of tap water to enter the hot water tank 10. The hot water in the hot water tank 10 flows into the collection tank 5 through the overflow pipe 6. The cooling water collection pump 1 is turned on, allowing the water to enter the subsequent circulating water pool. The cooling water discharged from the hot water tank 10 is automatically collected into the circulating water pool to supplement the evaporation loss of the circulating water pool, reduce the concentration ratio of the circulating water pool, reuse precious water resources, and reduce the production cost of the enterprise.

[0024] See Figure 1 A one-way valve 2 is installed on the second pipe 3. The circulating water return main pipe 7 is connected to the circulating water pool. A float level switch 4 is installed inside the collection tank 5. Valves are installed on the steam pipe 9 and the tap water pipe 8. A first pipe 13 is provided on the lower side of the collection tank 5. The first pipe 13 is detachably connected to the suction pipe 14 of the cooling water collection pump 1. The outlet of the cooling water collection pump 1 is provided with an output pipe 15, which is connected to the second pipe 3.

[0025] See Figure 2-4 The first pipe 13 connects to the straw 14, and the output pipe 15 connects to the second pipe 3, and they are detachably connected to each other. An outer sleeve 16 is fixedly provided on the outer surface of both the first pipe 13 and the output pipe 15. A rubber ring 17 is fitted on the outer surface of both the straw 14 and the second pipe 3. A sealing cylinder 18 is also fixedly fitted on the outer surface of both the straw 14 and the second pipe 3. A rubber ring 23 is provided on the inner side of the sealing cylinder 18, and a rubber ring 39 is provided on the inner side of the outer sleeve 16. Multiple square blocks 20 are arranged in a ring on the outer surface of the straw 14 and the second pipe 3. A hook-shaped rod 21 is hinged to each square block 20. A locking cylinder 22 is threadedly fitted on the outer surface of both the first pipe 13 and the output pipe 15. The first pipe 13 connects to the straw 14. 4. Output pipe 15 connects to pipe 2 3. These connections are detachable. The purpose of this detachment is to ensure the pump body can be removed, allowing for immediate replacement should it be damaged during use, and facilitating subsequent factory repairs. Specifically, the suction pipe 14 is inserted into pipe 1 13, with rubber ring 1 17 contacting the inner wall of pipe 1 13 to ensure a sealed connection. Then, pipe 1 13 is inserted into the sealing cylinder 18, with rubber ring 2 23 covering the outer surface of the inserted end of pipe 1 13. Finally, the sealing cylinder 18 is inserted into the outer sleeve 16, with rubber ring 3 19 inside the outer sleeve 16 covering the outer surface of the sealing cylinder 18, ensuring a multi-layered sealing connection. Afterwards, the hook rod 21 is manually rotated, with its end abutting against the outer side of the outer sleeve 16. Figure 4 Then rotate the locking cylinder 22 to enclose all the hook rods 21, thus completing the storage and fixing of the hook rods 21. The number of hook rods 21 is at least three.

[0026] In specific work, refer to Figure 1 When the hot water tank 10 cools down, it opens the valve on the tap water pipe 8, allowing a large amount of tap water to enter the hot water tank 10 through its pipe. The hot water in the hot water tank 10 then flows into the collection tank 5 through the overflow pipe 6. When the float level switch 4 detects that the water level has reached the upper limit of the collection tank 5, the cooling water collection pump 1 turns on and pumps the water into the circulating water return main pipe 7 through the one-way valve 2, allowing the water to enter the subsequent circulating water pool. When the float level switch 4 detects that the water level has reached the lower limit of the collection tank 5, the cooling water collection pump 1 turns off. Due to the presence of the one-way valve 2, circulating water cannot enter the collection tank 5. Through the control of the float level switch 4, the cooling water discharged from the hot water tank 10 is automatically collected into the circulating water pool, replenishing the evaporation loss of the circulating water pool, reducing the concentration ratio of the circulating water pool, reusing precious water resources, and reducing the company's production costs.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
