[0031] (1) This utility model provides a circulating pump for liquid transportation, including a filter tube, a circular funnel, several filter holes, a bend, and a cleaning mechanism and a driving mechanism disposed within the filter tube. The liquid flowing within the filter tube drives the driving mechanism to start, which in turn drives the cleaning mechanism to start.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0038] like Figure 1 , Figure 2 As shown, a circulating pump for liquid transfer includes: a circulating pump body 10, a motor 11, a filter structure, a drive mechanism, and a cleaning mechanism.

[0039] A circulating pump body 10 has an inlet pipe 13 fixedly installed on one side and an outlet pipe 12 fixedly installed at the upper end; a motor 11 is installed on the side of the circulating pump body 10 away from the inlet pipe 13 and is driven and connected to the circulating pump body 10; a filter structure is installed at the opening of the inlet pipe 13, communicates with and is fixedly connected to the inlet pipe 13; a drive mechanism is installed inside the filter mechanism and connected to the filter mechanism; and a cleaning mechanism is installed inside the filter mechanism, located between the drive mechanism and the inlet pipe 13, and connected to the filter mechanism.

[0040] The motor 11 is started, driving the circulation pump to begin operation. The circulating liquid enters the inlet pipe 13 through the filter pipe 1. The liquid flowing within the filter pipe 1 drives the drive mechanism, which in turn activates the cleaning mechanism. The cleaning mechanism continuously cleans the inner wall of the circular funnel 2. Under the action of the water flow, the cleaned impurities mixed with the water flow into the bend pipe 4 and then flow back to the filter pipe 1 on the side of the drive mechanism away from the circular funnel 2. Compared to existing technologies, this avoids clogging of the filter holes 3.

[0041] like Figure 1 , Figure 2 As shown, the filtration mechanism includes: a filter tube 1, a circular funnel 2, several filter holes 3, and a bent tube 4.

[0042] A filter tube 1, whose axis coincides with the axis of the inlet pipe 13, is located at the opening of the inlet pipe 13, and one end of which is connected to and fixedly connected to the inlet pipe 13; a circular funnel 2, whose axis coincides with the axis of the cleaning pipe, is located inside the cleaning pipe and fixedly connected to the cleaning pipe, with its larger end located away from the inlet pipe 13; a plurality of filter holes 3, evenly spaced on the circular funnel 2, and each penetrating the side wall of the circular funnel 2; and a bent tube 4, located inside the filter tube 1, between the circular funnel 2 and the inlet pipe 13, with one end connected to and fixedly connected to the smaller end of the circular funnel 2, and the other end penetrating to the outside of the filter tube 1 and connected to the side of the filter tube 1 away from the circular funnel 2 of the driving mechanism.

[0043] The liquid flowing inside the filter tube 1 enters the inlet pipe 13 of the circulation pump through several filter holes 3 on the side wall of the circular funnel 2. Due to the special design of the circular filter tube 1, under the impact of the liquid flow, some of the filter impurities accumulated on the inner side wall of the circular funnel 2 will mix with some of the water flow and enter the bend 4, and then flow back to the filter tube 1 on the side of the drive mechanism away from the circular funnel 2.

[0044] like Figure 1 As shown, the cleaning mechanism includes: a cleaning rod 5 and a scraper 6.

[0045] The cleaning rod 5 has its axis coincident with the axis of the circular funnel 2 and is disposed inside the circular funnel 2. One end of the rod, away from the water inlet pipe 13, extends to the outside of the circular funnel 2 and is fixedly connected to the driving mechanism. The scraper 6 has its side surfaces coincident with the axes of the circular funnel 2 and the cleaning rod 5, and is disposed at an inclination inside the circular funnel 2. One edge of the scraper is in close contact with the inner side wall of the circular funnel 2, and the edge of the scraper 6 near the water inlet pipe 13 is fixedly connected to the cleaning rod 5. The scraper 6 is disposed at an inclination in a rotational direction.

[0046] The drive mechanism drives the cleaning rod 5 to rotate, and the rotating cleaning rod 5 drives the scraper 6 to rotate. At this time, the scraper 6 continuously scrapes and cleans the impurities accumulated on the inner wall surface of the circular funnel 2. Due to the direction setting of the scraper 6 and the action of water flow, the impurities and liquid accumulated on the side of the scraper 6 enter the bend pipe 4.

[0047] like Figure 1 As shown, the driving mechanism includes: a limiting ring 7, an annular groove 9, and several fan blades 8.

[0048] A limiting ring 7, whose axis coincides with the axis of the filter tube 1, is disposed inside the filter tube 1 on the side of the circular funnel 2 away from the water inlet pipe 13, and is slidably connected to the filter tube 1. The sliding axis of the limiting ring 7 coincides with its axis, and the limiting ring 7 is located on the periphery of the end of the cleaning rod 5 away from the circular funnel 2. An annular groove 9 is disposed at the connection between the limiting ring 7 and the filter tube 1. Several fan blades 8 are disposed inside the limiting ring 7, one end of which is fixedly connected to the inner side wall of the limiting ring 7, and the other end is fixedly connected to the side of the cleaning rod 5. The several fan blades 8 are arranged symmetrically about the axis of the limiting ring 7.

[0049] The liquid flowing in the inlet pipe 13 drives several fan blades 8 to rotate, and the several fan blades 8 simultaneously drive the limit ring 7 and the cleaning rod 5 to rotate.

[0050] like Figure 1 As shown, the circular funnel 2 is made of metal, the bent tube 4 is made of metal, and the fan blades 8 are made of metal.

[0051] The above settings ensure that the circular funnel 2, the bend 4, and the several fan blades 8 do not deform under the impact of the circulating liquid, so as not to affect the normal operation of the equipment.

[0052] like Figure 1 As shown, it includes: a base 14, which is disposed on the lower side of the motor 11, and its upper end face is bolted to the motor 11.

[0053] The stability of the motor 11 and the circulating pump during operation can be improved by setting the base 14.

[0054] like Figure 1 As shown, it includes: four casters 15, which are respectively disposed on the lower end face of the base 14 and fixedly connected to the base 14, and are respectively located at the four corners of the lower end face of the base 14.

[0055] The four casters 15 effectively improve the ease of moving the circulation pump.

[0056] like Figure 1 As shown, it includes: a plurality of heat sinks 16, which are respectively disposed on the periphery of the motor 11 and respectively fixedly connected to the motor 11.

[0057] By setting up several heat sinks 16, the heat dissipation function of the motor 11 can be effectively improved, further ensuring the long-term effective operation of the circulating pump.

[0058] In use, the motor is started, driving the circulation pump to begin operation. The circulating liquid enters the inlet pipe through the filter pipe. The liquid flow in the inlet pipe simultaneously drives several fan blades to rotate, which in turn rotate the limiting ring and the cleaning rod. The rotating cleaning rod drives the scraper to rotate, continuously scraping away impurities accumulated on the inner wall of the circular funnel. Due to the scraper's direction and the water flow, impurities and some liquid accumulated on the scraper's side enter the bend pipe and flow back through it to the filter pipe on the side of the fan blades furthest from the circular funnel, where they are filtered and cleaned again.

[0059] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
