[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 and Figure 2The utility model provides an embodiment: a hierarchical filtering device of a heat exchange station, comprising a heat exchange device 1, a protective shell 3 is fixedly connected to the top wall of the heat exchange device 1, a blower 4 is fixedly installed on the inner bottom wall of the protective shell 3, a delivery pipe 5 is connected to the left output end of the blower 4, a circular one-way nozzle 6 is connected to the left end of the delivery pipe 5, an outer wall of the circular one-way nozzle 6 is fixedly connected to the middle of the inner wall of the filter tank 7, a filter plate 8 is fixedly installed on the left side of the inner wall of the filter tank 7, a liquid inlet valve 21 is connected to the left rear end of the filter tank 7, and the filter The left and right sides of the bottom wall of the tank 7 are connected with a liquid outlet valve 20, the right output end of the protective shell 3 is connected with a delivery pipe 9, the bottom end of the delivery pipe 9 is connected with a through pipe 10, the front and rear ends of the through pipe 10 are connected with nozzles 11, the outsides of the two nozzles 11 are fixedly connected with filter boxes 12, the inner walls of the two filter boxes 12 are slidably mounted with filter shells 13, the left sides of the two filter boxes 12 are connected with conversion shells 15, the adjacent sides of the two conversion shells 15 are connected to the front and rear sides of the heat exchange device 1, and the left side of the filter tank 7 is provided with a circulation mechanism 2;

[0030] Specifically, when the blower 4 is started, airflow is delivered to the delivery pipe 1 5 and the delivery pipe 2 9. The airflow delivered by the delivery pipe 1 5 reaches the annular one-way nozzle 6, and the high-pressure airflow is sprayed onto the filter plate 8, and its force is sufficient to dredge the particles accumulated on the filter plate 8 after the initial filtration. In order to clean the equipment more comprehensively, two nozzles 11 are also designed. These two nozzles 11 can accurately spray high-pressure airflow into the corresponding filter housing 13. It makes it possible to clean the particles inside the filter housing 13. Through this automated cleaning method, we avoid the tedious process of manual removal and cleaning. More importantly, this method reduces the risk of reduced filtration efficiency due to particles clogging the filter plate 8 and the filter housing 13.

[0031] Reference Figure 1 and Figure 3 The circulation mechanism 2 includes a servo motor 201, the right side of the servo motor 201 is fixedly connected to the left side of the filter tank 7, the output end of the servo motor 201 passes through the left side of the filter tank 7 and is fixedly connected to a rotating column 202, the middle and lower part of the rotating column 202 is fixedly connected to a slow flow plate 203, the upper and lower sides of the outer wall of the rotating column 202 are fixedly connected to rotating plates 204, and the inner walls of the two rotating plates 204 are fixedly installed with filter elements 205;

[0032] Specifically, when the servo motor 201 is started, the rotating column 202 starts to rotate. The rotation of the rotating column 202 drives the slow flow plate 203 and the two rotating plates 204 to rotate synchronously. The function of the slow flow plate 203 is to change the flow path of the liquid so that the liquid generates centrifugal force inside the filter tank 7, that is, the centrifugal force to which the liquid is subjected during the rotation process. This centrifugal force reduces the flow rate of the liquid, thereby increasing the contact time between the liquid and the filter element 205. The filter element 205 is made of high-efficiency filter material, and has good filtering performance and a long service life. When the liquid flow rate is reduced, the filter element can more fully capture and filter impurities and particulate matter in the liquid, thereby improving the filtering effect.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The front side of the heat exchange device 1 is fixedly connected with a control switch 16, and the control switch 16 is electrically connected to the blower 4 and the servo motor 201 respectively; the front side of the control switch 16 is provided with a protective shell 17, and the rear side of the protective shell 17 is rotatably connected to the front side of the heat exchange device 1 through a hinge; the top walls of the two filter boxes 12 are both provided with inclined surfaces;

[0034] Specifically, the device can be opened and closed through the control switch 16 electrically connected to the blower 4 and the servo motor 201 respectively, the control switch 16 can be protected by the protective shell 17, and the nozzle 11 can spray airflow through the two inclined surfaces.

[0035] Reference Figure 1 The outer wall of the delivery pipe 5 is fixedly installed with a rubber pad 19, and the outer wall of the rubber pad 19 is fixedly connected to the top wall of the filter tank 7; the top walls of the two filter shells 13 are fixedly connected with handles 14; the bottom wall of the filter tank 7 and the bottom wall of the heat exchange device 1 are fixedly connected with a support frame 18;

[0036] Specifically, the rubber pad 19 makes it easy to protect the outer wall connection of the delivery pipe 5, the two handles 14 make it easy to pull out the filter housing 13, and the two support frames 18 make the device more stable when working.

[0037] Working principle: When filtering begins, the liquid to be heat exchanged enters the interior of the filter tank 7 through the liquid inlet valve 21, and by starting the servo motor 201, the rotating column 202 drives the slow flow plate 203 and the two rotating plates 204 to rotate, thereby generating centrifugal force of the liquid inside the filter tank 7, thereby reducing the flow rate of the liquid, so that it can be fully filtered with the filter element 205, thereby improving the filtering effect, so that the filtered liquid enters the interior of the heat exchange device 1 for heat exchange, and after a period of use, by starting the blower 4, when the delivery pipe 1 5 and the delivery pipe 2 9 deliver the airflow, the annular one-way nozzle 6 can spray high-pressure airflow on the filter plate 8, so that the particulate matter accumulated after the filter plate 8 completes the preliminary filtration can be dredged, and the two nozzles 11 can spray high pressure on the corresponding filter housing 13, so that the filter plate 8 and the filter housing 13 can be dredged, so that the situation of manual removal and cleaning is avoided, and the possibility of affecting the filtering efficiency due to the clogging of the filter plate 8 and the filter housing 13 by particulate matter is reduced, thereby completing the work of heat exchange multi-stage filtration.
