Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the utility model.

[0032] Referring to Figures 1-5 As shown in the figure, the utility model provides a cooling water prefiltering device, including fixed frame 1, two jar bodies 2 are fixedly connected on fixed frame 1, input valve 3 and connecting pipe 4 are fixedly connected on jar body 2, and two connecting pipes 4 are communicated through three-way pipe 7;

[0033] First valve 5 and second valve 6 are communicated on connecting pipe 4, and second valve 6 is located between first valve 5 and jar body 2;

[0034] Jar body 2 is provided with filter core assembly 15 and rotating assembly 9 for rotating filter core assembly 15;

[0035] Filter core assembly 15 and input end and output end correspond and communicate with input valve 3 and connecting pipe 4 respectively, and the corresponding positions of filter core assembly 15 input end, output end and input valve 3 and connecting pipe 4 can be interchanged by rotating filter core assembly 15 through rotating assembly 9.

[0036] By setting two sets of filter core assembly 15, one filter core assembly 15 is cleaned, and the other one keeps running, so that the continuity of filtration can be ensured, and the production efficiency is not affected by equipment downtime.

[0037] In addition, the backwashing time of filter core assembly 15 is only a few minutes, so it is only necessary to start cleaning filter core assembly 15 one by one within a few minutes before the cleaning cycle of filter core assembly 15 ends, so as not to affect the filtering effect of filter core assembly 15.

[0038] As an optional embodiment, input valve 3 corresponds to connecting pipe 4, and input valve 3 and connecting pipe 4 are on the same axis.

[0039] The filter core assembly 15 comprises a cylindrical shell 16 arranged in the tank body 2, and the tank body 2 and the cylindrical shell 16 are both cylindrical, two through holes are formed in the cylindrical shell 16, which are respectively the input end and the output end of the filter core assembly 15, and the two through holes are fixedly connected with sealing rings 18, and the sealing rings 18 are in gap cooperation with the inner wall of the tank body 2, and the two sealing rings 18 are matched with the input valve 3 and the connecting pipe 4, and the two through holes are communicated with the input valve 3 and the connecting pipe 4 through the two sealing rings 18, and the cylindrical shell 16 is fixedly connected with the multi-stage filter core 17;

[0040] By rotating the assembly 9, the filter core assembly 15 is rotated by half a circle, so that the original input end and the output end of the filter core assembly 15 correspond to the connecting pipe 4 and the input valve 3 respectively, at this time, the side of the filter core assembly 15 carrying dirt corresponds to the connecting pipe 4, the input valve 3 is opened, and the cooling water enters the filter core assembly 15, and the dirt adsorbed on the multi-stage filter core 17 can be washed away by the cooling water, and the cooling water and the dirt will flow out through the second valve 6, and the sealing ring 18 can seal the filter core assembly 15 and the input valve 3 and the connecting pipe 4, thereby realizing backwashing of the filter core assembly 15 and improving the efficiency of cleaning the filter core assembly 15.

[0041] The multi-stage filter core 17 is composed of a plurality of independent filter cores arranged in a straight line array, and the filtering precision of the independent filter cores increases in the direction from the input valve 3 to the connecting pipe 4, and the specific material and composition of the independent filter core are both prior art and will not be described here.

[0042] The rotating assembly 9 comprises a servo motor 13 and a rotating shaft 14, the servo motor 13 is fixedly connected to the top of the tank body 2, and the rotating shaft 14 is vertically rotatably connected to the top of the tank body 2, and the lower end of the rotating shaft 14 penetrates through the tank body 2 and is fixedly connected to the top of the cylindrical shell 16.

[0043] The axis of the rotating shaft 14 is the same as that of the tank body 2 and the cylindrical shell 16, so that the sealing ring 18 can be accurately sealed and communicated with the input valve 3 and the connecting pipe 4.

[0044] The bottom of the tank body 2 is open, and the bottom of the tank body 2 is fixedly connected with a water leakage detection assembly 8.

[0046] Firstly, the open design of the water leakage detection assembly 8 can make a small amount of cooling water flow out of the input valve 3 and the connecting pipe 4, avoiding stagnation, and the design that the water immersion sensor 12 is higher than the bottom port of the funnel 10 is to avoid the contact between the small amount of water and the water immersion sensor 12, causing false alarm;

[0047] If the sealing ring 18 leaks at the communication position of the input valve 3, the water flow will surge, and the downward flowing cooling water will inevitably contact the water immersion sensor 12, which has a network connection function and can upload information to the terminal in real time, so that the staff can know whether there is a leak.

[0048] With the above structure, the two input valves 3 are communicated with the input end of the cooling water system, and the three-way pipe 7 is communicated with the output end of the cooling water system, the cooling water enters the filter core assembly 15 in the tank body 2, and is filtered by the filter core assembly 15, and the filtered cooling water flows out through the three-way pipe 7;

[0049] The dirt in the cooling water will be intercepted on the side of the multi-stage filter core 17 corresponding to the input valve 3, when the multi-stage filter core 17 needs to be cleaned, the input valve 3 and the first valve 5 corresponding to the multi-stage filter core 17 to be cleaned are closed, and the second valve 6 is opened, then the filter core assembly 15 is rotated by half a circle by rotating the assembly 9, so that the original input end and the output end of the filter core assembly 15 correspond to the connecting pipe 4 and the input valve 3 respectively, at this time the side of the filter core assembly 15 carrying dirt corresponds to the connecting pipe 4, the input valve 3 is opened, the cooling water enters the filter core assembly 15, and the dirt adsorbed on the multi-stage filter core 17 can be washed away by the cooling water, and the cooling water and the dirt will flow out through the second valve 6;

[0050] Finally, the filter core assembly 15 is restored to its original position by rotating the assembly 9, so that the single filter core with the highest fineness in the multi-stage filter core 17 corresponds to the connecting pipe 4 again, and then the input valve 3 is opened again, so that the cooling water can flush the dirt attached to the single filter core with the highest fineness, and the dirt flows out from the second valve 6;

[0051] At this point, the filter core assembly 15 is completely cleaned, the second valve 6 is closed and the first valve 5 is opened, so that the filter core assembly 15 can continue to filter the cooling water system.

[0052] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
