Due to the baffle, guide holes, and baffle mechanism, the shell-side flow resistance of the water-cooled baffle heat exchanger for coal mines is small, vibration can be effectively eliminated, and the service life is extended. There is no heat exchange blind area on the shell side of the water-cooled baffle heat exchanger for coal mines, the heat transfer area is large, the heat exchange performance is good, and it has the characteristics of small size and easy assembly and disassembly;

[0004] The above patent still has the following deficiencies: (1) The defect that foreign matter and impurities are easily accumulated inside the device. Since the liquid may contain particles, suspended matter, impurities, etc., these substances will be deposited on the heat exchange surface when passing through the heat exchanger, forming a thermal resistance layer, which hinders the transfer of heat and causes the heat exchange efficiency of the heat exchanger to decrease;

[0005] (2) The defect of cold water backflow may be caused by improper operation. When the pressure of the cold water supply system is insufficient, the cold water may flow back due to the pressure difference, which may lead to uneven temperature distribution inside the heat exchanger, resulting in local overheating or overcooling, and easily causing thermal stress on the equipment materials. In the long run, it may cause equipment damage or shorten its service life.

[0006] Therefore, a water-cooled baffle heat exchanger is urgently needed to solve the above problems. Utility Model Content

[0037] The baffle 12 is fixed inside the tank 2, and the copper tube 11 is inserted inside the baffle 12, and the partitions 13 are fixed on both sides of the copper tube 11;

[0038] The second connecting shell 8 is installed on one side of the tank body 2, and a first water outlet 10 is fixed on one side of the second connecting shell 8;

[0039] A first connecting shell 3 is fixed to the other side of the tank body 2, and a first water inlet 5 is fixed to one side of the first connecting shell 3;

[0040] The filter structure 4 is arranged inside the first connection shell 3. The filter structure 4 includes a fixing seat 406 fixed to one side of the first connection shell 3, a support shell 407 fixed to one side of the fixing seat 406, a reverse osmosis membrane 404 installed inside the support shell 407, a filter sheet 405 arranged inside the reverse osmosis membrane 404, and a sewage discharge assembly installed on one side of the support shell 407;

[0041] The flow-stopping structure 9 is arranged inside the first water inlet 5 and is used to limit the flow direction of the liquid inside the first water inlet 5 .

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the sewage discharge assembly includes a support shell 407 fixed on one side of the guide shell 401, a sewage pipe 402 installed at the bottom of the guide shell 401, and a sewage valve 403 installed at the bottom of the sewage pipe 402, the sewage pipe 402 extends to the inside of the first connecting shell 3 and is connected to the guide shell 401, the fixing seat 406 and the first water inlet 5 are located on the same horizontal center line, the surface of the support shell 407 is evenly opened with holes, and the support shell 407 and the fixed The fixed seat 406 is an integrated structure, and cold water enters the interior of the fixed seat 406 through the first water inlet 5. Then, the cold water is affected by the water pressure and passes through the reverse osmosis membrane 404 and the filter plate 405. The large volume foreign matter in the cold water is filtered out by the filter plate 405. Then, the reverse osmosis membrane 404 removes dissolved salts, colloids, microorganisms, organic matter, etc. in the cold water, so that clean cold water enters the interior of the first connecting shell 3. The drain valve 403 can be opened to discharge the foreign matter accumulated in the guide shell 401 through the drain pipe 402.

[0043] like Figure 2 , Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the flow-stopping structure 9 includes a support frame 901 installed inside the fixed seat 406, a moving rod 902 sliding inside the support frame 901, a spring 904 fixed on one side of the moving rod 902, a rubber pad 905 fixed on the outside of the spring 904, a baffle ring 906 fixed inside the first water inlet 5, and a spring 904 installed at a middle position between the baffle 903 and the support frame 901, and the baffle 903 forms a telescopic structure between the spring 904 and the baffle ring 906. Structure, the baffle 903 and the baffle ring 906 are located on the same horizontal center line. When the water pressure inside the first water inlet 5 is normal, the cold water pushes the baffle 903 to move backward, so that the baffle 903 is separated from the baffle ring 906, and the cold water enters the first connecting shell 3 normally. When the water pressure inside the first water inlet 5 is too low, the elastic force of the spring 904 is used to push the rubber pad 905 to contact the baffle ring 906, so as to seal the first water inlet 5 and prevent hot water from entering the first water inlet 5. The movement of the moving rod 902 is guided by the support frame 901.

[0044] Specifically, when the water-cooled baffle heat exchanger is in use: cold water is introduced into the interior of the first connecting shell 3 through the first water inlet 5, so that the cold water enters the copper tube 11, and hot water is injected into the interior of the tank body 2 through the second water inlet 14, so that the cold water absorbs the heat of the hot water through the copper tube 11 and heats up. At the same time, the hot water is guided by multiple groups of baffles 12 to make the hot water fully contact with the copper tube 11, eliminating dead zones in the flow, and facilitating the generation of turbulence in the hot water to accelerate the transfer of heat. The cold water that absorbs heat is discharged through the first water outlet 10.

[0045] Cold water enters the interior of the fixing seat 406 through the first water inlet 5, and then the cold water is affected by the water pressure and passes through the reverse osmosis membrane 404 and the filter 405, and the large volume of foreign matter in the cold water is filtered out by the filter 405, and then the reverse osmosis membrane 404 removes the dissolved salts, colloids, microorganisms, organic matter, etc. in the cold water, so that the clean cold water enters the interior of the first connecting shell 3, and the drain valve 403 is opened to discharge the foreign matter accumulated in the guide shell 401 through the drain pipe 402.

[0046] When the water pressure inside the first water inlet 5 is normal, the cold water pushes the baffle 903 to move backward, separating the baffle 903 from the baffle ring 906, allowing the cold water to enter the first connecting shell 3 normally. When the water pressure inside the first water inlet 5 is too low, the elastic force of the spring 904 is used to push the rubber pad 905 to contact the baffle ring 906, thereby sealing the first water inlet 5 and preventing hot water from entering the first water inlet 5. The movement of the moving rod 902 is guided by the support frame 901.

[0047] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
