[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is in conjunction with the appendix Figures 1-3 The water supply and return device of this utility model embodiment will be described in detail.

[0028] The water supply and return device of this utility model embodiment includes a cooling water jacket and at least one water supply and return component 10. The cooling water jacket has multiple inlets and multiple outlets. The multiple inlets are divided into at least one inlet group, and the multiple outlets are divided into at least one outlet group. The at least one inlet group corresponds one-to-one with the at least one outlet group. The at least one water supply and return component 10 corresponds one-to-one with the at least one inlet group and the at least one outlet group. One end of the water supply and return component 10 is connected to multiple inlets of the corresponding inlet group, and the other end of the water supply and return component 10 is connected to multiple outlets of the corresponding outlet group.

[0029] The water supply and return device of this utility model groupes the cooling water jacket according to the cooling requirements. Each water supply and return component 10 corresponds to a set of inlet groups and a set of outlet groups of the cooling water jacket. This allows each water supply and return component 10 to supply water to multiple inlets of the inlet group corresponding to it and receive return water from multiple outlets of the outlet group corresponding to it. This improves the cooling efficiency of the cooling water jacket and realizes a modular water supply and return setting. The structure is simple and easy to maintain.

[0030] Specifically, such as Figures 1-3 As shown, when there is one group of inlet ports and one group of outlet ports, there is one supply and return water assembly 10. The outlet end of the supply and return water assembly 10 is connected to multiple inlet ports, and the inlet end of the supply and return water assembly 10 is connected to multiple outlet ports. When there are multiple groups of inlet ports and multiple groups of outlet ports, there are multiple supply and return water assemblies 10. The multiple supply and return water assemblies 10 are connected to multiple inlet ports and multiple outlet ports in a one-to-one correspondence. Each supply and return water assembly 10 corresponds to one group of inlet ports and one group of outlet ports. The outlet end of each group of supply and return water assemblies 10 is connected to multiple inlet ports of the corresponding inlet port group to supply water to the multiple inlet ports. The inlet end of each group of supply and return water assemblies 10 is connected to multiple outlet ports of the corresponding outlet port group to receive return water from the multiple outlet ports, thereby realizing the circulation of water in the cooling water jacket.

[0031] In this embodiment, the modular water supply and return assembly 10 can improve the circulation efficiency of water in the cooling water jacket, thereby improving the cooling efficiency. On the other hand, it can reduce the frequency of pipe blockage, extend the maintenance cycle, and reduce operating costs.

[0032] Optionally, the cooling water jacket can be grouped according to the location of multiple water inlets. For example, the water inlets on the furnace body are the first water inlet group, the water outlets on the furnace body are the first water outlet group, the water inlets on the furnace cover are the second water inlet group, and the water outlets on the furnace cover are the second water inlet group.

[0033] For example, there are 30 inlets and 30 outlets. The inlets are divided into two groups, each with 15 inlets. The outlets are divided into two groups, each with 15 outlets. Correspondingly, there are two water supply and return components 10. One water supply and return component 10 corresponds to the 15 inlets of one group and the 15 outlets of one group. The other water supply and return component 10 corresponds to the 15 inlets of the other group and the 15 outlets of the other group.

[0034] In some embodiments, the water supply and return assembly 10 includes at least one water supply main pipe 1 and at least one water return main pipe 2. The at least one water supply main pipe 1 is connected to a plurality of water inlets of the water inlet group corresponding to the water supply and return assembly 10, and the at least one water return main pipe 2 is connected to a plurality of water outlets of the water outlet group corresponding to the water supply and return assembly 10.

[0035] Specifically, the number of water supply main 1 and return main 2 is determined based on the total amount of cooling circulating water in the cooling water jacket. When the total amount of cooling circulating water in the cooling water jacket is small, the water supply and return assembly 10 includes one water supply main 1 and one return main 2; when the total amount of cooling circulating water in the cooling water jacket is large, the water supply and return assembly 10 includes multiple water supply mains 1 and multiple return mains 2. By flexibly adjusting the number of water supply mains 1 and return mains 2, the conveying performance of water supply mains 1 and return mains 2 can be improved, thereby increasing the water circulation efficiency.

[0036] Understandably, the water supply main pipe 1 is used to connect to the cold water pool, and the return water main pipe 2 is used to transport the return water to the circulating water pool or cooling tower for cooling. The water cooled by the cooling tower enters the cold water pool.

[0037] Optionally, the water supply main pipe 1 and the return water main pipe 2 are made of welded steel pipe, seamless steel pipe or stainless steel pipe.

[0038] In some embodiments, such as Figures 1-3 As shown, the water supply and return assembly 10 also includes a frame 3, on which the water supply main pipe 1 and the water return main pipe 2 are both located. By integrating the water supply main pipe 1 and the water return main pipe 2 onto the frame 3, the structural compactness of the water supply and return assembly 10 is improved, and maintenance of the water supply main pipe 1 and the water return main pipe 2 is facilitated.

[0039] Optionally, the frame 3, as a supporting component, can be formed by welding one or more of angle steel, channel steel, and I-beams to ensure the structural stability of the frame 3.

[0040] Optionally, the length direction of the frame 3 is consistent with the extension direction of the main water supply pipe 1 and the extension direction of the main water return pipe 2, with the main water supply pipe 1 and the main water return pipe 2 located on opposite sides of the width direction of the frame 3. The main water supply pipe 1 is fixed to the frame 3 by pipe clamps. The main water return pipe 6 can be placed directly on the frame 3 or fixed to the frame 3 by pipe clamps.

[0041] In some embodiments, such as Figures 1-3As shown, the return water main 2 has an upstream end 21 and a downstream end 22. The return water main 2 extends from the upstream end 21 towards the downstream end 22 and is arranged at a downward inclination. Water in the return water main 2 flows from the upstream end 21 to the downstream end 22. By setting the return water main 2 to be arranged at a downward inclination in the direction of water flow, that is, the downstream end 22 of the return water main 2 is lower than the upstream end 21, the water in the return water main 2 flows to the downstream end 22 under the action of gravity, which helps to improve the flow efficiency of water in the return water main 2, thereby improving the water circulation efficiency.

[0042] Optionally, the slope of the return water main 2 is greater than 0.005, that is, the length of the return water main 2 extends horizontally by one meter, and the height difference between the two ends of the return water main 2 is 5 millimeters.

[0043] In some embodiments, such as Figures 1-3 As shown, the water supply and return assembly 10 also includes a vent pipe 4, which is located at the upstream end 21 of the return water main 2 and connects the return water main 2 to the outside. The vent pipe 4 extends in the vertical direction, and its lower end is connected to the upstream end 21 of the return water main 2 (in the opposite direction of water flow). By setting the vent pipe 4 at the upstream end 21 of the return water main 2, it serves two purposes: firstly, it balances the air pressure inside and outside the return water main 2, ensuring smooth water flow; secondly, the air inside the return water main 2 can flow to the outside through the upstream end 21 of the return water main 2 and the vent pipe 4, preventing air accumulation in the return water main 2 and ensuring smooth water flow.

[0044] Optionally, the material of the vent pipe 4 is the same as that of the return water main pipe 2.

[0045] In some embodiments, such as Figures 1-3 As shown, the water supply and return assembly 10 also includes multiple water supply branch pipes 5. One end of each water supply branch pipe 5 is connected to the main water supply pipe 1, and the other end of each water supply branch pipe 5 is connected to a corresponding inlet of the inlet group of the water supply and return assembly 10. The inlet ends of the multiple water supply branch pipes 5 are respectively connected to the main water supply pipe 1, and the outlet ends of the multiple water supply branch pipes 5 are connected to a corresponding inlet of the inlet group of the water supply and return assembly 10. The one-to-one connection between the multiple water supply branch pipes 5 and the multiple inlets helps to improve the water supply efficiency of the water supply and return device.

[0046] Optionally, the water supply branch pipe 5 may be made of welded steel pipe, seamless steel pipe, or stainless steel pipe. The water supply branch pipe 5 is adapted to the inlet of the cooling water jacket; for example, the pipe diameter of the water supply branch pipe 5 is the same as the pipe diameter of the inlet.

[0047] In some embodiments, such as Figures 1-3As shown, the water supply and return assembly 10 also includes multiple return water branch pipes 6. One end of each return water branch pipe 6 is connected to the main return water pipe 2, and the other end of each return water branch pipe 6 is connected to a corresponding outlet of the outlet group of the water supply and return assembly 10. The inlet end of each return water branch pipe 6 is connected to a corresponding outlet of the outlet group of the water supply and return assembly 10, and the outlet end of each return water branch pipe 6 is connected to the main return water pipe 2. The one-to-one connection between the multiple return water branch pipes 6 and the multiple outlets helps to improve the return water efficiency of the water supply and return device.

[0048] Optionally, the return water branch pipe 6 is made of welded steel pipe, seamless steel pipe, or stainless steel pipe. The return water branch pipe 6 is adapted to the outlet of the cooling water jacket. For example, the diameter of the return water branch pipe 6 is the same as the diameter of the outlet, or the diameter of the return water branch pipe 6 is one size larger than the diameter of the outlet.

[0049] In some embodiments, the water supply and return assembly 10 further includes a frame 3 and a return water collection tank 7. Both the main return water pipe 2 and the return water collection tank 7 are located on the frame 3. The lower end of the return water collection tank 7 is connected to the main return water pipe 2, and one end of the return water branch pipe 6 extends into the return water collection tank 7 to transport return water to the return water collection tank 7. The return water collection tank 7 serves two purposes: firstly, it collects the return water, achieving a stable flow effect; secondly, it facilitates the observation of the return water status of each return water branch pipe 6 through the return water collection tank 7.

[0050] Specifically, such as Figures 1-3 As shown, the return water collection tank 7 is located on the frame 3 and above the return water main pipe 2. The outlet end of the return water branch pipe 6 extends into the return water collection tank 7 to transport the water flowing out of the outlet of the cooling water jacket to the return water collection tank 7. The lower end of the return water collection tank 7 is connected to the return water main pipe 2 to transport the water in the return water collection tank 7 to the return water main pipe 2.

[0051] Optionally, the return water collection tank 7 is welded to the frame 3.

[0052] Optionally, the return water collection tank 7 is made of steel plate, galvanized steel plate, enamel steel plate, powder-coated steel plate or stainless steel plate, with a thickness of 3.0mm-5.0mm.

[0053] In some embodiments, the side wall of the return water collection tank 7 is provided with a through observation hole 71, and the return water collection tank 7 includes a baffle 72, which is rotatably disposed at the observation hole 71.

[0054] Specifically, such as Figure 1 and Figure 3As shown, by setting an observation hole 71 on the return water collection tank 7, the return water status of each return water branch pipe 6 can be observed more intuitively, realizing single-point monitoring. For example, the water flow status, flow rate and flow rate of the return water branch pipe 6 can be directly observed. For example, one can also put one's hand in to feel the water temperature. On the other hand, the gas in the return water branch pipe 6 can flow into the return water collection tank 7 and be discharged to the outside through the observation hole 71, alleviating the gas accumulation phenomenon in the return water main pipe 2 and improving the water flow efficiency.

[0055] In some embodiments, the water supply and return assembly 10 further includes a connecting pipe 8, one end of which is connected to the return water collection tank 7, and the other end of which is connected to the return water main pipe 2.

[0056] Specifically, such as Figure 1 As shown, the upper end of the connecting pipe 8 is connected to the lower end of the return water collection tank 7, and the lower end of the return water collection tank 7 is connected to the upper end of the return water main pipe 2. The connection between the return water collection tank 7 and the return water main pipe 2 is achieved through the setting of the connecting pipe 8.

[0057] Optionally, the connecting pipe 8 is determined according to the return water volume. There can be one or more connecting pipes 8. Multiple connecting pipes 8 are arranged at intervals in the extension direction of the return water main pipe 2. The arrangement of multiple connecting pipes 8 can improve the efficiency of water flow from the return water collection tank 7 to the return water main pipe 2, thereby improving the return water efficiency.

[0058] In some embodiments, the water supply and return assembly 10 further includes a backup branch pipe, which is located between the main water supply pipe 1 and the inlet and / or between the main return pipe 2 and the outlet. The backup branch pipe allows for temporary addition of water jacket inlets and outlets on-site and also facilitates maintenance.

[0059] Specifically, the backup branch pipe is located between the main water supply pipe 1 and the inlet and / or between the main return pipe 2 and the outlet. This can be understood as: the backup branch pipe is located between the main water supply pipe 1 and the inlet; or, the backup branch pipe is located between the main return pipe 2 and the outlet; or, there are two sets of backup branch pipes, one set located between the main water supply pipe 1 and the inlet, and the other set located between the main return pipe 2 and the outlet. In this embodiment, the backup branch pipe is located between the main water supply pipe 1 and the inlet and between the main return pipe 2 and the outlet.

[0060] For example, each group of spare branch pipes consists of one, two, three, or four.

[0061] In some embodiments, such as Figure 2 As shown, the main water supply pipe 1 is equipped with a main valve 911, a first flow detection element 921, and a pressure detection element 93. By installing the main valve 911, the first flow detection element 921, and the pressure detection element 93 on the main water supply pipe 1, it is convenient to monitor the water supply flow and water supply pressure.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the water supply branch pipe 5 is equipped with a branch valve 912. By installing the branch valve 912 on the water supply branch pipe 5, it is convenient to adjust the water supply flow rate of the water supply branch pipe 5 according to the return water temperature and flow rate of the return water branch pipe 6.

[0063] In some embodiments, such as Figure 3 As shown, the return water branch pipe 6 is equipped with a temperature detection element 94 and a second flow detection element 922. By installing the temperature detection element 94 and the second flow detection element 922 on the return water branch pipe 6, it is convenient to detect the return water temperature and return water flow, thereby facilitating the assessment of the cooling status of the cooling water jacket.

[0064] Optionally, the main valve 911, the first flow detection element 921, the pressure detection element 93, the branch valve 912, the temperature detection element 94, and the second flow detection element 922 all have local display and remote transmission functions, realizing real-time monitoring of water supply and return, and thus enabling remote monitoring of the status of the water supply and return device. The main valve 911 and the branch valve 912 can be operated manually, electrically, or pneumatically.
