[0026] Reference below Figure 1-Figure 4 A flushing device 100 for an engine 200 according to an embodiment of the first aspect of the present utility model is described.

[0027] like Figure 1-Figure 4 As shown, the flushing device 100 of the engine 200 according to the first embodiment of the utility model includes: a coolant tank 10, a pump body 20 and a first filter 40.

[0028] Specifically, the coolant tank 10 is used to hold coolant, the pump body 20 is arranged in the coolant tank 10, the pump body 20 is connected to the liquid inlet 201 of the engine 200 through the first pipeline 30, one end of the first filter 40 is connected to the coolant tank 10, and the other end of the first filter 40 is connected to the liquid outlet 202 of the engine 200 through the second pipeline 50.

[0029] For example, in Figure 1-Figure 4 In the example of , the capacity of the coolant tank 10 can be 100L, the pump body 20 is arranged in the coolant tank 10 and is covered by the coolant, the liquid outlet 202 of the pump body 20 is connected to the liquid inlet 201 of the engine 200 through the first pipeline 30, and the pump body 20 is used to provide a driving force to pump the coolant to the engine 200. The liquid inlet 201 of the first filter 40 is connected to the liquid outlet 202 of the engine 200 through the second pipeline 50, and the liquid outlet 202 of the first filter 40 is connected to the coolant tank 10.

[0030] Specifically, when a bench antifreeze test is performed on an engine 200 that has not been used for a long time, the liquid inlet 201 of the engine 200 can be connected to the first pipeline 30, and the liquid outlet 202 of the engine 200 can be connected to the second pipeline 50. Then, the pump body 20 is started. At this time, the clean coolant in the coolant tank 10 is pumped to the first pipeline 30 through the pump body 20, and then flows to the inside of the engine 200 through the first pipeline 30 and the liquid inlet 201 of the engine 200. After the coolant circulates inside the engine 200, it flows to the second pipeline 50 through the liquid outlet 202 of the engine 200. At this time, the coolant in the second pipeline 50 contains rust particles and other impurities. The coolant with more impurities is filtered by the first filter 40 and then flows to the coolant. Such a cycle can not only remove the rust inside the engine 200 and the impurities on the antifreeze, but also the first filter 40 outside the engine 200 can filter the rust and impurities to make the coolant flowing into the coolant tank 10 cleaner. Optionally, the flow rate of the pump body 20 is 12m 3 / h.

[0031] Therefore, when cleaning an engine 200 that has not been used for a long time, the flushing device 100 can be used to achieve automatic cleaning, avoiding chemical damage to the cleaning personnel, saving labor costs, and automation can greatly improve work efficiency. At the same time, it can remove as many impurities in the engine 200 as possible, ensuring that the engine 200 has a good heat exchange efficiency and avoiding overheating of the engine 200.

[0032] According to the flushing device 100 of the engine 200 of the embodiment of the utility model, by arranging the pump body 20 between the liquid inlet 201 of the engine 200 and the coolant tank 10, and arranging the first filter 40 between the liquid outlet 202 of the engine 200 and the coolant tank 10, when the flushing device 100 is working, the pump body 20 can pump clean coolant to the engine 200, and the turbid coolant flowing out of the engine 200 is filtered by the first filter 40 and then flows to the coolant. In this way, the engine 200 can be automatically cleaned, chemical damage to the cleaning personnel can be avoided, labor costs can be saved, and work efficiency can be greatly improved. At the same time, as many impurities in the engine 200 as possible can be removed, ensuring that the engine 200 has a good heat exchange efficiency and avoiding overheating of the engine 200.

[0033] According to some embodiments of the present utility model, the second pipeline 50 includes a first pipe section 501, a second pipe section 502 and a third pipe section 503, one end of the first pipe section 501 is connected to the other end of the first filter 40, one end of the second pipe section 502 is connected to the other end of the first pipe section 501, the other end of the second pipe section 502 is connected to the first liquid outlet 203 of the engine 200, one end of the third pipe section 503 is connected to the other end of the first pipe section 501, the other end of the third pipe section 503 is connected to the second liquid outlet 204 of the engine 200, and the third pipe section 503 is connected in parallel with the second pipe section 502.

[0034] Among them, the coolant in the coolant tank 10 can flow to the engine 200 through the pump body 20 and the liquid inlet 201 of the engine 200, the coolant flows inside the engine 200 to clean the engine 200, and the turbid coolant flowing out from the first liquid outlet 203 of the engine 200 can flow to the first filter 40 through the second pipe segment 502 and the first pipe segment 501, and flow to the coolant tank 10 after being filtered by the first filter 40; and / or the coolant in the coolant tank 10 can flow to the engine 200 through the pump body 20 and the liquid inlet 201 of the engine 200, the coolant flows inside the engine 200 to clean the engine 200, and the turbid coolant flowing out from the second liquid outlet 204 of the engine 200 can flow to the first filter 40 through the third pipe segment 503 and the first pipe segment 501, and flow to the coolant tank 10 after being filtered by the first filter 40. In this way, the coolant in the coolant tank 10 can clean different pipes in the engine 200, ensuring that the interior of the engine 200 can be completely cleaned.

[0035] Further, refer to Figure 1-Figure 4The flushing device 100 of the engine 200 further includes a first valve 60 and a second valve 70. The first valve 60 is disposed on the second pipe section 502 and is used to control the connection and disconnection between the first liquid outlet 203 and the first pipe section 501. The second valve 70 is disposed on the third pipe section 503 and is used to control the connection and disconnection between the second liquid outlet 204 and the first pipe section 501. In other words, the flow path of the coolant in the engine 200 is controlled by controlling the working states of the first valve 60 and the second valve 70.

[0036] For example, when only the first valve 60 is in an open state, the coolant in the coolant tank 10 flows to the engine 200 through the pump body 20, and the coolant flows out from the first liquid outlet 203 after circulating and cleaning in the engine 200, and flows to the coolant tank 10 through the second pipe section 502, the first pipe section 501 and the first filter 40, so as to achieve a small circulation flushing of the engine 200. Similarly, when only the second valve 70 is in an open state, the coolant in the coolant tank 10 flows to the engine 200 through the pump body 20, and the coolant flows out from the second liquid outlet 204 after circulating and cleaning in the engine 200, and flows to the coolant tank 10 through the third pipe section 503, the first pipe section 501 and the first filter 40, so as to achieve a small circulation flushing of the engine 200.

[0037] According to some embodiments of the present invention, Figure 1-Figure 4 As shown, the first pipeline 30 includes a first sub-tube 301, a second sub-tube 302, a third sub-tube 303 and a fourth sub-tube 304, one end of the first sub-tube 301 is connected to the pump body 20, one end of the second sub-tube 302 is connected to the other end of the first sub-tube 301, one end of the third sub-tube 303 is connected to the above-mentioned other end of the first sub-tube 301, the third sub-tube 303 is connected in parallel with the second sub-tube 302, one end of the fourth sub-tube 304 is respectively connected to the other end of the second sub-tube 302 and the other end of the third sub-tube 303, and the fourth sub-tube 304 is connected to the liquid inlet 201.

[0038] The coolant in the coolant tank 10 can flow to the engine 200 through the pump body 20 and the liquid inlet 201 of the engine 200, and the coolant flows inside the engine 200 to clean the engine 200. The coolant in the coolant tank 10 can flow to the inside of the engine 200 through the pump body 20, the first sub-pipe 301, the second sub-pipe 302, and the fourth sub-pipe 304; and / or, the coolant in the coolant tank 10 can flow to the inside of the engine 200 through the pump body 20, the first sub-pipe 301, the third sub-pipe 303, and the fourth sub-pipe 304. In this way, the coolant in the coolant tank 10 can clean different pipelines in the engine 200, ensuring that the inside of the engine 200 can be completely cleaned.

[0039] Furthermore, the flushing device 100 of the engine 200 further includes a third valve 80 and a fourth valve 90. The third valve 80 is provided on the second sub-pipe 302 and is used to control the communication between the liquid inlet 201 and the coolant tank 10. The fourth valve 90 is provided on the third sub-pipe 303 and is used to control the communication between the liquid inlet 201 and the coolant tank 10. For example, Figure 4 In the example, when only the third valve 80 is in the open state, the coolant in the coolant tank 10 flows to the engine 200 through the pump body 20, the first sub-pipe 301, the second sub-pipe 302 and the fourth sub-pipe 304. After the coolant circulates and cleans in the engine 200, it flows out from the first liquid outlet 203 and flows to the coolant tank 10 through the second pipe section 502, the first pipe section 501 and the first filter 40, so as to realize a small circulation flushing of the engine 200.

[0040] Likewise, if Figure 1 As shown, when only the fourth valve 90 is in the open state, the coolant in the coolant tank 10 flows to the engine 200 through the pump body 20, the first sub-pipe 301, the third sub-pipe 303 and the fourth sub-pipe 304. After the coolant circulates and cleans in the engine 200, it flows out from the second liquid outlet 204 or the first liquid outlet 203, and flows to the coolant tank 10 through the second pipeline 50 and the first filter 40, so as to realize a large-circulation flushing of the engine 200.

[0041] Furthermore, a second filter 110 is provided on the second sub-pipe 302, and the second filter 110 is located on a side of the third valve 80 adjacent to the liquid inlet 201. This arrangement can filter the coolant flowing to the engine 200, making the coolant flowing to the engine 200 cleaner and reducing damage to the engine 200.

[0042] The specific working mode of the flushing device 100 according to the embodiment of the utility model is as follows:

[0043] like Figure 2 As shown, the first valve 60, the second valve 70 and the fourth valve 90 are opened, and the third valve 80 is closed. At this time, the coolant in the coolant tank 10 flows to the engine 200 through the pump body 20, the first sub-pipe 301, the fourth valve 90 and the fourth sub-pipe 304, and the turbid coolant in the engine 200 can flow out through the first liquid outlet 203 and the second liquid outlet 204. The turbid coolant flows to the coolant tank 10 through the second pipeline 50 and the first filter 40, thereby realizing a large-circulation flushing of the engine 200, and the engine 200 can be flushed as quickly as possible.

[0044] like Figure 3As shown, the first valve 60, the second valve 70 and the third valve 80 are opened, and the fourth valve 90 is closed. At this time, the coolant in the coolant tank 10 flows to the engine 200 through the pump body 20, the first sub-pipe 301, the third valve 80, the second filter 110 and the fourth sub-pipe 304, so that the coolant flowing to the engine 200 is cleaner, and the turbid coolant in the engine 200 can flow out through the first liquid outlet 203 and the second liquid outlet 204, and the turbid coolant flows to the coolant tank 10 through the second pipeline 50 and the first filter 40, so that the engine 200 is flushed in a large cycle using clean coolant, so that the engine 200 is flushed more cleanly.

[0045] like Figure 4 As shown, the first valve 60 and the third valve 80 are opened, and the fourth valve 90 and the second valve 70 are closed. At this time, the coolant in the coolant tank 10 flows to the engine 200 through the pump body 20, the first sub-pipe 301, the third valve 80, the second filter 110 and the fourth sub-pipe 304, so that the coolant flowing to the engine 200 is cleaner, and the turbid coolant in the engine 200 can flow out through the first liquid outlet 203, and the turbid coolant flows to the coolant tank 10 through the first valve 60 and the first filter 40, so that the engine 200 is flushed in a small cycle with clean coolant, so that the engine 200 is flushed more cleanly.

[0046] According to some embodiments of the present invention, at least one electric heater 120 is disposed in the coolant tank 10, and the electric heater 120 is disposed adjacent to the bottom of the coolant tank 10. Figure 1 As shown, two electric heaters 120 are provided in the coolant tank 10, and the two electric heaters 120 are used to heat the coolant. Raising the coolant temperature to 40°C to 45°C can effectively improve the circulation of the coolant and the degradation of impurities, thereby enabling the engine 200 to be flushed more cleanly.

[0047] According to some embodiments of the present invention, Figure 1 As shown, a filter screen 130 is provided at the liquid inlet of the pump body 20, and the filter screen 130 at least covers the liquid inlet of the pump body 20. The coolant in the coolant tank 10 will also contain some impurities after long-term use.
