[0031] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described in detail below in conjunction with the drawings in the embodiments of the present application, and the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by those skilled in the art without creative work on the basis of the embodiments of the present application shall belong to the protection scope of the present application.

[0032] like Figure 1 As shown, a dirt remover with a self-cleaning function includes an equipment barrel 1 and a support 2 for supporting the equipment barrel 1. A primary filter screen 3 is arranged in the equipment barrel 1, a water inlet 11 is arranged on the equipment barrel 1 below the primary filter screen 3, and a water outlet 12 is arranged on the equipment barrel 1 above the primary filter screen 3. The circulating water of the heating system enters the equipment barrel 1 from the water inlet 11, flows out from the water outlet 12 after being filtered by the primary filter screen 3, thereby filtering the circulating water. A sewage pipe 13 connected to the internal space of the equipment barrel 1 is arranged at the bottom of the equipment barrel 1.

[0033] like Figure 1 As shown, a cleaning device 4 is provided above the primary filter 3 in the equipment cylinder 1 .

[0034] like Figure 4 As shown, the cleaning device 4 includes a flushing pipe network, the inlet end of which passes through the side wall of the equipment barrel 1 and extends to the outside of the equipment barrel 1, and is connected to the flushing water source through a pipeline. The flushing pipe network is provided with a water spray hole 42 facing the primary filter 3.

[0035] As a specific implementation, the flushing pipe network described in this embodiment includes a flushing main pipe 411, and the flushing main pipe 411 extends radially along the equipment cylinder 1. One end of the flushing main pipe 411 is fixedly connected to the side wall of the equipment cylinder 1 by welding, and the other end of the flushing main pipe 411 passes through the side wall of the equipment cylinder 1 and extends to the outside of the equipment cylinder 1. The flushing main pipe 411 is provided with a flushing branch pipe 412 connected to the flushing main pipe 411, and one end of the flushing branch pipe 412 facing the equipment cylinder 1 is fixedly connected to the side wall of the equipment cylinder 1 by welding. The flushing main pipe 411 and the flushing branch pipe 412 are both provided with water spray holes 42.

[0036] As a specific implementation, in this embodiment, both sides of the main flushing pipe 411 are provided with flushing branch pipes 412, and the flushing branch pipes 412 on both sides of the main flushing pipe 411 are staggered. Exemplarily, three flushing branch pipes 412 are provided on one side of the main flushing pipe 411, and two flushing branch pipes 412 are provided on the other side of the main flushing pipe 411.

[0037] In order to increase the flushing pressure during cleaning, a spray head (not shown in the figure) may be further provided on the water spray hole 42 .

[0038] Furthermore, if Figure 1 and Figure 2 As shown, the primary filter screen 3 is a conical structure with the top of the cone facing upward, and is arranged coaxially with the equipment barrel 1. There is a gap M between the lower edge of the primary filter screen 3 and the equipment barrel 1, and the lower edge of the primary filter screen 3 is fixedly connected to the equipment barrel 1 through a plurality of first tie bars 31 arranged radially along the circumferential direction.

[0039] As a specific implementation, six first tie bars 31 evenly arranged along the circumferential direction are provided between the primary filter screen 3 and the equipment cylinder 1 in this embodiment, one end of the first tie bar 31 is fixedly connected to the primary filter screen 3 by welding, and the other end of the first tie bar 31 is fixedly connected to the equipment cylinder 1 by welding. There is a gap M of 5 mm between the lower edge of the primary filter screen 3 and the equipment cylinder 1.

[0040] The reason for this design is that when the circulating water enters the equipment barrel 1 through the water inlet 11, due to the direction of the cone top, the impurities and dirt retained on the lower side of the primary filter 3 after filtration will move downward along the cone surface and are not easy to hang on the primary filter 3. After the filtered circulating water enters the upper side of the primary filter 3, the impurities will fall on the upper side of the primary filter 3 after precipitation. When the cleaning device 4 is turned on, under the action of the impurities' own gravity and the flushing water, the impurities will flow downward along the cone surface of the primary filter 3, and return to the lower side of the primary filter 3 through the gap between the primary filter 3 and the equipment barrel 1, and finally settle to the bottom of the equipment barrel 1, and can be discharged through the sewage pipe 13 at the bottom.

[0041] Furthermore, if Figure 1 As shown, a secondary filter screen 5 is arranged above the cleaning device 4 in the equipment barrel 1, and the filtering accuracy of the secondary filter screen 5 is higher than that of the primary filter screen 3. That is, the secondary filter screen 5 can filter finer impurities. The water outlet 12 is located above the secondary filter screen 5. The flushing main pipe 411 and the flushing branch pipe 412 are provided with a water spray hole 42 that can spray water toward the secondary filter screen 5, so as to clean the secondary filter screen 5.

[0042] As a specific implementation, the primary filter 3 in this embodiment is used for coarse filtration with a filtration accuracy of 4 mm, and the secondary filter 5 is used for fine filtration with a filtration accuracy of 2 mm. The main flushing pipe 411 and the branch flushing pipe 412 are evenly covered with water spray holes 42 .

[0043] Furthermore, if Figure 1 and Figure 3 As shown, the secondary filter screen 5 is arranged obliquely. The reason for this design is that when the circulating water after the coarse filtration is finely filtered by the inclined secondary filter screen 5, the filtered impurities will adhere to the lower side of the secondary filter screen 5. Since the secondary filter screen 5 is arranged obliquely, the impurities will move downward along the inclined surface and are not easy to hang on the secondary filter screen 5.

[0044] As a specific implementation method, Figure 3 As shown, in this embodiment, the lower end of the secondary filter screen 5 is fixedly connected to the equipment cylinder 1 through a second tie bar 51. The second tie bar 51 is located above the secondary filter screen 5, one end of the second tie bar 51 is fixedly connected to the secondary filter screen 5 by welding, and the other end of the second tie bar 51 is fixedly connected to the equipment cylinder 1 by welding.

[0045] Furthermore, if Figure 1 and Figure 4As shown, a first control valve 43 is provided at the inlet of the flushing main pipe 411. When the filter needs to be cleaned, the first control valve 43 is opened, and flushing water enters and is sprayed out through the water spray hole 42, thereby flushing the primary filter 3 and the secondary filter 5.

[0046] Furthermore, if Figure 5 As shown, a detection pipe 14 is provided between the water inlet 11 and the water outlet 12, and a differential pressure transmitter 141 is provided on the detection pipe 14. The differential pressure transmitter 141 can detect the pressure difference between the water inlet 11 and the water outlet 12, and feed back the detection result to the controller, and the controller determines whether the filter needs to be cleaned according to the differential pressure feedback from the differential pressure transmitter 141. When the controller determines that the filter needs to be cleaned according to the differential pressure feedback from the differential pressure transmitter 141, the controller controls the first control valve 43 to open, so as to flush the primary filter 3 and the secondary filter 5.

[0047] Furthermore, if Figure 1 As shown, the drain pipe 13 is provided with a second control valve 131. When the controller determines that the filter needs to be cleaned according to the pressure difference feedback from the pressure difference transmitter 141, the controller controls the second control valve 131 to open, thereby discharging the dirt generated by cleaning from the drain pipe 13.

[0048] Furthermore, if Figure 1 As shown, an exhaust valve 15 is provided at the top of the equipment cylinder 1, and an anti-clogging filter 151 is provided at the inlet of the exhaust valve 15 in the equipment cylinder 1. The anti-clogging filter 151 adopts a high-precision filter to prevent impurities from entering the exhaust valve 15 and clogging the exhaust valve 15. The exhaust valve 15 can prevent the gas in the pipeline from being unable to be discharged, thereby causing gas blockage.
