Detailed Implementation

[0014] like Figure 1As shown, this utility model includes a heating tank 1 containing a cleaning medium, and a first guide pipe 14 and a second guide pipe 15, both of which extend into the heating tank 1 at one end. A stainless steel filter countersunk head 2 is installed at one end of the first guide pipe 14 extending into the heating tank 1, and a first internal thread interface 8 is installed at the other end of the first guide pipe 14. A stainless steel countersunk head 13 is installed at one end of the second guide pipe 15 extending into the heating tank 1, and a second internal thread interface 10 is installed at the other end of the second guide pipe 15. A microchannel product 9 to be cleaned is connected between the first internal thread interface 8 and the second internal thread interface 10. A first filtration mechanism and a power transmission pressurization mechanism are installed on the first guide pipe 14, and a second filtration mechanism is installed on the second guide pipe 15.

[0015] It should be noted that by setting up a heating tank to regulate the medium temperature, the rinsing temperature can be controlled, making it suitable for rinsing various microchannel products. The heating tank contains a stainless steel filter screen to filter impurities in the raw fluid. The first and second filters further filter impurities in the raw fluid medium, and the third and fourth filters filter impurities in the microchannel products. The system uses first and second internal threaded interfaces for installing and replacing microchannel products. A flow guide pipe and a one-way valve guide the flow throughout the system, while a variable frequency water pump and a high-pressure ball valve provide power and pressure. Through the close coordination between temperature control, filtration, and power transmission and pressurization, it is suitable for various aerospace internal flow channel products, solving the problem of difficult cleaning of aerospace internal flow channel products and improving cleaning efficiency. The system has a simple and reasonable structure.

[0016] In this embodiment, the power transmission and pressurization mechanism includes a one-way valve 4, a variable frequency water pump 5, and a high-pressure ball valve 6 connected in sequence, and the first filtration mechanism includes a first filter 3 installed at the front end of the one-way valve 4 and a second filter 7 installed at the rear end of the high-pressure ball valve 6.

[0018] In actual use, the first filter 3 is a 40um filter, and the filter element can be removed and replaced by the user. The second filter 7 is a 5um filter, and the filter element can be removed and replaced by the user. The first guide pipe 14 sequentially filters impurities in the raw fluid through the stainless steel filter head 2, the 40um filter and the 5um filter to ensure the quality of the cleaning medium entering the microchannel product 9.

[0019] In this embodiment, the second filtration mechanism includes a third filter 11 and a fourth filter 12 connected in sequence.

[0020] In this embodiment, the filtration accuracy of the third filter 11 is lower than that of the fourth filter 12.

The fourth filter 12 uses a 5um filter, and the filter element can be removed and replaced by the user. The second guide pipe 15 filters the impurities in the medium flowing out of the microchannel product 9 step by step through the 40um filter and the 5um filter to ensure the quality of the medium flowing back into the heating tank 1.

[0022] In actual use, the first guide pipe 14 and the second guide pipe 15 are both DN25 guide pipes, the one-way valve 4 is an M20*1.5 one-way valve, and the first internal thread interface 8 and the second internal thread interface 10 are M20*1.5 internal thread interfaces.

[0023] In use, the heating tank 1 is adjusted to the target temperature, the rinsing temperature of the medium is controlled, the variable frequency water pump 5 is started, and the high-pressure ball valve 6 is opened. The cleaning medium enters the microchannel product 9 for cleaning through the stainless steel filter head 2, 40um filter, one-way valve 4, variable frequency water pump 5, high-pressure ball valve 6, and 5um filter. The medium then flows back into the heating tank 1 through the outlet of the microchannel product 9, the 40um filter, the 5um filter, and the stainless steel filter head 13. The filter elements of the first filter 3, the second filter 7, the third filter 11, and the fourth filter 12 can be removed and replaced by the user. This invention is suitable for rinsing various microchannel products. The guide pipe and one-way valve play a guiding role in the entire system, and the variable frequency water pump and high-pressure ball valve provide power and pressure. Through the close cooperation between temperature control, filtration, and power transmission and pressurization, the problem of difficult cleaning of aerospace internal flow channel products is solved, and the cleaning efficiency of aerospace internal flow channel products is improved. This invention is suitable for cleaning various aerospace internal flow channel products.
