Description

Technical Field

[0001] This utility model belongs to the field of industrial water circulation technology, specifically a hot and cold water mixing device. Background Technology

[0002] Factories with high water demand typically have dedicated circulating water tanks to ensure water supply while minimizing water waste and conserving water resources. The use of circulating water is particularly common in production lines requiring heat exchange.

[0003] A circulating water tank generally includes an outlet and an inlet. The outlet is connected to the inlet of the water system, and the water for the water system is supplied from the outlet of the circulating water tank. The inlet is connected to the return end of the water system. Water used by the water system is discharged through the return end and flows back to the circulating water tank from the inlet. After certain treatment, it re-enters the circulation.

[0004] Currently, many circulating water tanks suffer from uneven mixing in their mixing chambers, resulting in poor performance. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] This utility model discloses a hot and cold water mixing device, including a mixing tank, a hot water pipe assembly, a cold water pipe assembly, and an outlet pipe assembly. The hot water pipe assembly and the cold water pipe assembly supply hot water and cold water to the mixing tank, respectively. The outlet pipe assembly discharges the mixed water in the mixing tank. The hot water pipe assembly includes a hot water main pipe and branch pipes. The hot water main pipe runs horizontally through one side of the mixing tank, and several branch pipes are distributed on the hot water main pipe. The hot water in the hot water main pipe flows into the mixing tank through the branch pipes.

[0008] Preferably, the cold water pipe assembly includes a main cold water pipe, a thin cold water pipe, and a nozzle. The main cold water pipe is located on one side of the mixing tank, and multiple thin cold water pipes are installed on the main cold water pipe. The thin cold water pipes are inserted into the mixing tank, and each thin cold water pipe is equipped with a nozzle.

[0009] Preferably, the cold water main pipe is coaxial with the hot water main pipe, and multiple cold water capillary tubes are evenly distributed around the cold water main pipe, with the central axis of the cold water capillary tubes parallel to the central axis of the hot water main pipe.

[0010] Preferably, the several branch pipes are distributed in multiple layers, with 6 branch pipes in each layer, and the 6 branch pipes in each layer are evenly distributed on the hot water main.

[0011] Preferably, the water outlet pipe assembly includes water outlet branch pipes and water outlet main pipe, with multiple water outlet branch pipes distributed in parallel and on the same horizontal plane, and the multiple water outlet branch pipes connected to the water outlet main pipe.

[0012] Preferably, the nozzle sprays water in the direction of the adjacent cold water capillary.

[0013] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0014] This utility model discloses a hot and cold water mixing device. Hot water is input through a hot water main pipe, and then discharged through a branch pipe, collecting around the hot water main pipe to form a hot water zone. At the same time, cold water is output from the corresponding cold water main pipe and distributed through a cold water thin pipe. Finally, it is sprayed through a nozzle to form a cold water layer around the hot water zone. As hot water continues to be poured in, the water pressure in the hot water zone increases, causing the hot water and cold water layer to mix and form a mixed water that diffuses in all directions. Finally, it is pumped away by multiple outlet pipes for use. Attached Figure Description

[0029] See attached document Figure 1-3A hot and cold water mixing device according to this embodiment includes a mixing tank 100, a hot water pipe assembly 200, a cold water pipe assembly 300, and an outlet pipe assembly 400. The hot water pipe assembly 200 and the cold water pipe assembly 300 respectively supply hot water and cold water into the mixing tank 100. The outlet pipe assembly discharges the mixed water in the mixing tank 100. The hot water pipe assembly 200 includes a hot water main pipe 210 and a branch pipe 220. The hot water main pipe 210 extends laterally through one side of the mixing tank 100. Several branch pipes 220 are distributed on the hot water main pipe 210. The hot water in the hot water main pipe 210 flows into the mixing tank 100 through the branch pipes 220.

[0030] The cold water pipe assembly 300 in this embodiment includes a cold water main pipe 310, cold water capillary pipes 320, and a nozzle 330. The cold water main pipe 310 is located on one side of the mixing tank 100. Multiple cold water capillary pipes 320 are provided on the cold water main pipe 310. The cold water capillary pipes 320 are inserted into the mixing tank 100. Each cold water capillary pipe 320 is provided with a nozzle 330.

[0031] In this embodiment, the cold water main pipe 310 is coaxial with the hot water main pipe 210, and a plurality of cold water thin pipes 320 are evenly distributed around the cold water main pipe 310, with the central axis of the cold water thin pipes 320 being parallel to the central axis of the hot water main pipe 210.

[0032] In this embodiment, the several branch pipes 220 are distributed in multiple layers, with 6 branch pipes 220 in each layer, and the 6 branch pipes 220 in each layer are evenly distributed on the hot water main pipe 210.

[0033] The water outlet pipe assembly 400 in this embodiment includes a water outlet branch pipe 410 and a water outlet main pipe 420. Multiple water outlet branches 410 are distributed in parallel and are on the same horizontal plane. Multiple water outlet branches 410 are connected to the water outlet main pipe 420.

[0034] In this embodiment, the nozzle 330 sprays towards the adjacent cold water capillary tube 320. This design creates a ring-shaped spray pattern, forming a cold water layer that prevents the hot water from spreading and avoids excessive hot water overflow, thus preventing uneven heating.

[0035] Working principle: Hot water is input through the hot water main pipe 210, and then discharged through the branch pipe 220, collecting around the hot water main pipe 210 to form a hot water zone. At the same time, the corresponding cold water main pipe 310 will also output cold water, which is distributed through the cold water thin pipe 320 and finally sprayed through the nozzle 330, forming a cold water layer around the hot water zone. As hot water continues to be poured in, the water pressure in the hot water zone increases, causing the hot water and cold water layer to mix and form mixed water that diffuses in all directions. Finally, it is drawn away by multiple outlet pipes 410 and discharged for use.

[0036] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
