Technical Field

[0001] The utility model relates to the technical field of assembled heat exchange units, in particular to a multi-stage filtering structure for assembled heat exchange units. Background Art

[0002] In order to improve the cleanliness of water used by users, existing prefabricated heat exchange units generally need to be equipped with a multi-stage filtration structure to fully filter the water source entering from the outside. For example, patent application number 202121812741.1 discloses an assembled heat exchange station, which flocculates large particles of impurities in the water by placing a flocculant into the filter chamber, then filters it through a stainless steel filter mesh, and then places activated carbon into the sedimentation chamber to adsorb and precipitate small particles of impurities in the water. Finally, the ozone inlet interface at the top of the disinfection chamber is connected to the external ozone inlet pipe, and ozone is introduced into the disinfection chamber to disinfect and clean the water in the disinfection chamber.

[0003] Although the above patent can filter, precipitate and disinfect user water input from the outside, thereby improving the cleanliness of user water, the following problems still exist in actual operation:

The multi-stage filter assembly includes a first filter screen 4, a second filter screen 5, a third filter screen 6 and an activated carbon filter screen 7 which are fixedly inserted into the filter pool 1 from left to right. The pore sizes of the first filter screen 4, the second filter screen 5 and the third filter screen 6 decrease from left to right, so that the water source entering from the outside can be filtered layer by layer.

[0031] In this embodiment, the top outer walls of the flocculation tank 2 and the disinfection tank 3 are fixedly connected to a common connecting beam 8, on which a driving assembly is provided. The lower outer walls of the flocculation tank 2 and the disinfection tank 3 are fixedly connected to a common support plate 9, on which a flocculant delivery assembly and an ozone delivery assembly are sequentially provided. A stirring assembly is provided in both the flocculation tank 2 and the disinfection tank 3.

[0032] In this embodiment, both stirring assemblies include a hollow rotating rod 10 rotatably mounted at one end of the connecting beam 8 and a plurality of hollow stirring rods 11 sequentially fixedly connected to the hollow rotating rod 10. The top of the hollow rotating rod 10 is an open structure, and the connection ends of all the hollow stirring rods 11 and the hollow rotating rod 10 are also open structures. The surfaces of all the hollow stirring rods 11 are provided with evenly distributed through holes.

[0033] In this embodiment, the drive assembly includes a drive motor 12 fixedly mounted on the middle outer wall of the bottom of the connecting beam 8, a double-groove pulley 13 fixedly mounted on the output shaft of the drive motor 12, and two single-groove pulleys 14 fixedly mounted on the upper parts of the two hollow rotating rods 10 in sequence. The output shaft of the drive motor 12 passes through the connecting beam 8, and the double-groove pulley 13 is sequentially connected to the two single-groove pulleys 14 through two transmission belts 15.

[0034] In this embodiment, the flocculant delivery assembly includes a pump body 16 and a flocculant storage tank 17 fixedly mounted on the top outer wall of the support plate 9 in sequence. The pumping end of the pump body 16 is connected to the flocculant storage tank 17 through a pipeline, and the delivery end of the pump body 16 is connected to the flocculant delivery pipe.

[0035] In this embodiment, the ozone delivery assembly includes an ozone generator 18 fixedly connected to the top outer wall of the support plate 9 and an ozone delivery pipe connected to the ozone generator 18. The ozone delivery pipe and the flocculant delivery pipe are respectively connected to the two hollow rotating rods 10 through a rotary joint 19;

[0036] In this embodiment, a water source connection pipe is provided on the flocculation tank 2, and an assembled heat exchanger base connection pipe is provided on the disinfection tank 3.

[0037] Example 2, reference Figure 1 and Figure 3-5 This embodiment is optimized based on the embodiment 1, specifically:

[0038] A cleaning assembly is provided on one side of the first filter 4, the second filter 5, and the third filter 6. The cleaning assembly includes a screw body 20 rotatably mounted on the filter tank 1, a cleaning brush 21, a screw nut 22 and a guide sleeve 24 fixedly embedded in the cleaning brush 21 in sequence, a guide shaft 23 fixedly connected to the filter tank 1, and a handwheel 25 fixedly connected to the outer wall of one end of the screw body 20;

[0039] Furthermore, the lead screw nut 22 is threadedly connected to the lead screw body 20, the guide sleeve 24 is slidably connected to the guide shaft 23, and the bristles of the three cleaning brushes 21 are in contact with the surfaces of the first filter 4, the second filter 5, and the third filter 6 respectively;

[0040] When cleaning is required, the screw body 20 is controlled to rotate by the handwheel 25, and then the screw nut 22 threadedly connected to the screw body 20 will drive the cleaning brush 21 to move under the guidance of the guide shaft 23 and the guide sleeve 24. In this way, by controlling the movement of the three cleaning brushes 21, the impurities attached to the surfaces of the first filter 4, the second filter 5 and the third filter 6 can be effectively cleaned, thereby reducing the probability of blockage.

[0041] The working principle of the utility model is as follows: first, the double-groove pulley 13 is controlled by the driving motor 12 to rotate, and then under the transmission effect of the transmission belt 15, the two single-groove pulleys 14 will drive the hollow stirring rods 11 on the two hollow rotating rods 10 to rotate;

[0042] Secondly, the external water source will enter the flocculation tank 2 through the water source pipe. At this time, the pump body 16 will extract the flocculant in the flocculant storage tank 17 and transport it to the hollow stirring rod 11 located in the flocculation tank 2, and spray it out from the through hole on it. In this way, with the stirring effect of the internal hollow stirring rod 11, the flocculant and the incoming water source can be evenly and fully mixed, and the large particles of impurities in the water liquid can be fully flocculated, thereby improving the flocculation effect.

[0043] Next, the water flows from the flocculation tank 2 to the filter tank 1, and after being filtered through the first filter screen 4, the second filter screen 5, the third filter screen 6 and the activated carbon filter screen 7 in the filter tank 1, it flows into the disinfection tank 3;

[0044] Finally, the ozone is transported by the ozone generator 18 through the ozone delivery pipe to the hollow stirring rod 11 located in the disinfection tank 3, and the ozone is sprayed out from the through hole thereon. In this way, with the stirring effect of the internal hollow stirring rod 11, the ozone can be evenly and fully mixed with the incoming water source, thereby increasing the ozone dissolution rate and improving the disinfection effect. Finally, the disinfected water source will flow into the assembled heat exchanger base from the assembled heat exchanger base connecting pipe, thus completing the entire filtration and purification process of the external water source.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
