Description

Technical Field

[0001] The invention belongs to the technical field of radiators, and in particular to a device and method for treating and inspecting the inner cavity of a radiator. Background Art

[0002] Radiators are used in railway locomotives, for example, to dissipate heat from liquid media such as oil or water. The radiator core has array-arranged fluid channels inside, including round tubes, flat tubes, plates, harmonica tubes, and other types, for the circulation of liquid media. The outside of the radiator core is equipped with heat dissipation fins that are densely arranged at a certain distance.

[0003] The oil and water radiators for railway electric locomotives include split and integral structures. The structures of the radiator cores, which are the core components, are basically similar. The radiator transfers the heat generated by the main transformer and traction converter to the aluminum alloy composite plate and the heat sink respectively through the circulation of cooling media such as transformer oil and water coolant in the fluid channels inside the oil and water radiator cores. After heat exchange with the cold air blown by the axial flow fan unit, the heat adsorbed by the heat sink is discharged outside the vehicle, which plays a role in reducing the temperature of the oil and water medium. When the two radiators are stacked vertically together and share a fan unit, it is also called a composite radiator.

[0004] After long-term use, the radiator will produce impurities in the inner cavity of the radiator core due to discharge of related electrical components, mechanical wear, emulsification of coolant and other reasons, polluting the internal working environment. Therefore, the inner cavity of the radiator needs to be cleaned and filtered regularly to prevent the normal operation of the main transformer and traction converter from being affected by excessive radiator contamination impurities. In some radiator inner cavity cleaning devices in the prior art, cleaning and rinsing are performed in separate areas, so that the radiator needs to be hoisted multiple times at different workstations, and the cleaning time is long, and the work efficiency is low. Summary of the invention

[0005] The purpose of the present invention is to provide a radiator inner cavity pollution treatment and inspection equipment and method, so as to solve the problem that the existing technology carries out the cleaning and rinsing of the radiator inner cavity in separate areas, so that the radiator needs to be lifted multiple times at the workstations of different processes, and the cleaning time is long and the work efficiency is low. By arranging an inner cavity cleaning and contamination detection device with cleaning and rinsing functions, the radiator can be cleaned and rinsed in the same area, reducing the number of times the radiator is lifted; and by combining the circulating cleaning of the cleaning liquid and the two-phase vibration cleaning of the liquid-gas mixed fluid, and combining with the clean water rinsing, the cleaning effect and efficiency of the inner cavity of the radiator are improved, the cleaning time is reduced, and the work efficiency is improved; and it can reduce the water consumption, reduce the use of corresponding pipelines and valves, reduce costs, and save environmental protection.

[0039] The radiator inner cavity pollution treatment and inspection device and method provided by the present invention have the following beneficial effects:

[0040] 1. In view of the problem that the prior art requires multiple people to work on the radiator at different workstations in different processes and requires frequent lifting and switching of the workstations, long cleaning time and low work efficiency, the radiator inner cavity pollution treatment and inspection equipment and method provided by the present invention, by providing an inner cavity cleaning and contamination detection device with cleaning and rinsing functions, the radiator can be cleaned and rinsed and the inner cavity contamination level can be inspected in the same area, which can improve the cleaning effect of the radiator inner cavity, reduce the number of times the radiator is lifted during the operation, improve work efficiency, reduce work intensity, and facilitate standardized operation and management; and the cleaning medium can be recycled, which can reduce water consumption, reduce costs, and save the environment. At the same time, in view of the problem in the prior art that when the inner cavity of the radiator is simply cleaned by circulating water, the internal dirt is difficult to remove when it is in the dead corner of the inner cavity. The radiator inner cavity pollution treatment and inspection equipment and method provided by the present invention, by combining the circulating cleaning of the cleaning liquid and the two-phase vibration cleaning of the liquid-gas mixed fluid, and combined with rinsing with clean water, can promote the separation and removal of dirt from the inner cavity of the radiator, can better and faster remove dirt, improve the cleaning effect and efficiency of the inner cavity of the radiator, reduce cleaning time, and improve work efficiency.

[0041] 2. The following problems exist in the prior art method of heating and drying the radiator as a whole by baking in an electric oven: (1) As an external heating method, its heating speed is slow. It takes at least 3 hours for a heating power of 24kW to heat the radiator 100 as a whole to above 80°C; (2) Since the inner cavity of the radiator is a honeycomb structure, water is distributed all over the internal surface after cleaning, and the drying area is large. The radiator body is completely relied on for heating and evaporating water, and the drying efficiency is extremely low; (3) The purge air is the same as the room temperature. After entering the inner cavity of the radiator, it objectively plays a role in cooling the radiator body, resulting in an unsatisfactory drying effect; the radiator inner cavity pollution treatment and inspection equipment and method provided by the present invention can use the hot air blower of the inner cavity drying device to send hot air into the inner cavity of the radiator for hot air purge and drying, thereby achieving heating, purge and rapid drying of the inner cavity of the radiator, thereby improving the heating speed, drying efficiency and drying effect, and reducing energy consumption; in addition, By setting up a drying station, the radiator can be dried at the drying station; and the drying station and the cleaning station can be interchangeable, so that the radiator can be cleaned, rinsed, checked for inner cavity contamination, and dried at one station, reducing the frequency of radiator lifting, reducing workload, and improving work efficiency; in addition, the hot air blower can adopt a ducted hot air blower, which can include an air inlet, a centrifugal fan, a heater, and a control component; the centrifugal fan pressurizes the inhaled air, and the heater heats the flowing air to a specified temperature; the hot air outlet temperature of the ducted hot air blower is adjustable and can be heated to a maximum of 300°C, which is suitable for heating and drying of various common radiators and similar parts, expanding the scope of application; in addition, the inner cavity drying device can be installed as a whole on the workbench, and a tool storage area can be provided at the bottom of the workbench, so that the lower space of the workbench can be used to place small pipe connectors and work tools, which is convenient for the storage and management of work tools.

[0042] 3. In view of the fact that there is no water collection and drainage device in the prior art, a large amount of water will fall from the disassembly and assembly of the pipeline during operation and cover the ground. Therefore, the work site must have a drainage ditch, which affects the on-site working environment and increases the construction workload and cost of the working environment. The radiator cavity pollution treatment and inspection equipment and method provided by the present invention can use a water collection tray to allow a large amount of cleaning liquid and water flowing from the disassembly and assembly of the pipeline to be discharged through a sewage pipe; a water trough, a baffle, a partition and an air inlet can also be set through a water-gas separation box, so that the upper part of the baffle is inclined to form an eaves shape, an air chamber is formed above the partition, and a water separation chamber is formed below, so that the water discharged during the drying process The gas mixture is separated and diverted; the gas separated from the water-gas mixture is discharged into the atmosphere through the water-gas separation box, and the separated water is discharged through the sewage pipe, so there is no need to set up drainage ditches at the work site, thereby ensuring the on-site working environment and reducing the construction volume and cost of the working environment; the water-gas separation box can be used in conjunction with the water collection tray or alone, which is flexible and convenient; in addition, the sewage pipe is easy to connect with the drainage pipe at the work site, so as to facilitate the discharge of the generated waste water, thereby reducing the application environment requirements and expanding the scope of application; in addition, the empty space of the water collection tray can be used to store large hoses such as cleaning pipes, return pipes, exhaust pipes, and high-temperature resistant pipes.

[0043] 4. In view of the problem that tap water is used to clean the inner cavity of the radiator in the prior art, which causes the calcium and magnesium ions in the tap water to have an adverse effect on the surface of the radiator, the radiator inner cavity pollution treatment and inspection equipment and method provided by the present invention can use a chemical cleaning agent mixed with industrial pure water to form a cleaning liquid, which is conducive to decontamination and cleaning of the radiator; the cleaning liquid prepared with industrial pure water (i.e., deionized water) or industrial pure water can be used to circulate and rinse the inner cavity of the radiator to avoid adverse effects on the surface of the radiator; the industrial pure water can be stored in a water storage barrel, which is convenient for adding to the cleaning water tank or the rinsing water tank through a water replenishment pump and a water replenishment pipeline.

[0044] 5. The radiator inner cavity pollution treatment and inspection equipment and method provided by the present invention, the control part of the inner cavity cleaning and contamination detection device, the cleaning pump, the water supply pump and other power devices are installed outside, which is convenient for installation, operation, daily maintenance and troubleshooting.

[0045] 6. The radiator inner cavity pollution treatment and inspection equipment and method provided by the present invention can reduce the middle size of the cleaning water tank and the rinsing water tank relative to the upper and lower sizes, that is, the cross-sectional area of ​​the middle is reduced to form a variable diameter rectangular parallelepiped structure, which helps to enhance the structural strength of the box.

[0046] 7.

[0072] Please refer to Fig.17 This embodiment also provides a method for treating and inspecting the inner cavity of a radiator. The method is implemented based on a device for treating and inspecting the inner cavity of a radiator provided in this embodiment, and includes a preparation stage, a cleaning stage, a rinsing stage, and an inspection stage. The preparation stage includes the following steps:

[0073] Step S11, adding cleaning liquid and rinsing water: adding cleaning liquid into the cleaning water tank 110, and adding rinsing water into the rinsing water tank 120;

[0074] Step S12, connecting the radiator: connecting one end of the cleaning pipe 140 to the inner cavity inlet 101 of the radiator 100, and connecting one end of the return pipe 150 to the inner cavity outlet 102 of the radiator 100;

[0075] The cleaning phase includes the following steps:

[0076] Step S21, connecting the cleaning water tank: operating the water suction electric reversing valve 161 and the water return electric reversing valve 182, so that the water suction pipeline 160 and the water return pipeline 180 between the other ends of the cleaning pipe 140 and the water return pipe 150 and the cleaning water tank 110 are opened;

[0077] It should be noted that in the step of connecting the cleaning water tank, the water outlet valve 171 is in a closed state;

[0078] Step S22, cleaning with cleaning liquid: start the cleaning pump 130, open the outlet valve 171, so that the cleaning liquid in the cleaning water tank 110 flows into the inner cavity of the radiator 100 through the water suction pipe 160, the outlet pipe 170 and the cleaning pipe 140 for cleaning, and then flows back to the cleaning water tank 110 through the return pipe 150 and the return pipe 180 for circulating cleaning liquid cleaning;

[0079] Step S23, liquid-gas two-phase oscillation cleaning: connect the air inlet valve 172 to the air outlet of the high-pressure gas source, open the air inlet valve 172, and allow the high-pressure gas to flow into the inner cavity of the radiator 100 through the water outlet pipe 170 and the cleaning pipe 140 to form a liquid-gas mixed fluid for liquid-gas two-phase oscillation cleaning, and then return to the cleaning water tank 110 through the return pipe 150 and the return pipe 180 for circulating liquid-gas two-phase oscillation cleaning;

[0080] It should be noted that, in the liquid-gas two-phase oscillation cleaning step, the air intake valve 172 can be partially opened, that is, the air intake valve 172 is opened, but the air intake valve 172 is not fully opened, so that the opening degree of the air intake valve 172 is not too large. For example, the air intake valve 172 can be opened a small amount so that the cleaning pipe 140 has obvious fluctuations.

[0081] The rinse phase includes the following steps:

[0082] Step S31, connecting the rinsing water tank: close the air inlet valve 171, open the water outlet valve 171, operate the water suction electric reversing valve 161 and the water return electric reversing valve 182 to switch the connection direction, so that the water suction pipeline 160 and the water return pipeline 180 between the other ends of the cleaning pipe 140 and the water return pipe 150 and the rinsing water tank 120 are opened;

[0083] Step S32, draining and rinsing: disconnect the other end of the return pipe 150 from the return pipe 180 and the return filter 181, connect the return pipe 150 to the drain pipe at the work site, start the cleaning pump 130, so that the rinsing water in the rinsing water tank 120 flows into the inner cavity of the radiator 100 through the water suction pipe 160, the water outlet pipe 170 and the cleaning pipe 140 for rinsing, and the rinsed water is discharged through the drain pipe;

[0084] Step S33, backflow rinsing: connect the other end of the return pipe 150 to the return pipe 180 and the return filter 181, start the cleaning pump 130, so that the rinsing water in the rinsing water tank 120 flows into the inner cavity of the radiator 100 through the water suction pipe 160, the water outlet pipe 170 and the cleaning pipe 140 for rinsing, and then flows back to the rinsing water tank 120 through the return pipe 150 and the return pipe 180 for circulating rinsing;

[0085] It should be noted that since the water used in the early stage of rinsing the radiator 100 contains a lot of cleaning liquid, it is not suitable to be recycled into the rinsing water tank 120, and it is necessary to drain and rinse first. When no cleaning liquid foam is observed in the water after drain and rinse, the drain and rinse are terminated and the reflux rinse is started;

[0086] The inspection phase includes the following steps:

[0087] Step S41, contamination level check: turn off the cleaning pump 130, open the return water filter 181, check the residual pollutants on the return water filter 181, if the residual pollutants do not meet the requirements, repeat the steps of the cleaning stage, the rinsing stage and the inspection stage, or only repeat the steps of the rinsing stage and the inspection stage until the residual pollutants meet the requirements.

[0088] Please refer to Figures 1 to 12 The radiator inner cavity pollution treatment and inspection equipment of this embodiment is connected in sequence by the cleaning water tank 110, the water suction pipe 160, the cleaning pump 130, the water outlet pipe 170, the cleaning pipe 140, the inner cavity of the radiator 100, the return pipe 150 and the return pipe 180 to form a cleaning liquid circulation path; the water outlet pipe 170 connected by the cleaning pump 130 is equipped with an air inlet valve 172 to connect the high-pressure gas to the cleaning liquid circulation path, so that the high-pressure gas and the cleaning liquid are mixed to form a liquid-gas mixed fluid; The water pipeline 160, the cleaning pump 130, the water outlet pipeline 170, the cleaning pipe 140, the inner cavity of the radiator 100, the return pipe 150 and the return pipe 180 are connected in sequence to form a rinsing circulation path, and the cleaning liquid circulation path and the rinsing circulation path can be switched through the water suction electric reversing valve 161 and the return water electric reversing valve 182; by installing a return water filter 181 on the return water pipe 180, and by observing the pollutant situation of the return water filter 181, the cleaning situation and residual pollution situation of the radiator 100 can be checked and judged. In addition, after the cleaning liquid with dirt flowing out of the inner cavity of the radiator 100 flows through the return water filter 181, the dirt impurities returned with the cleaning liquid are filtered, so as to prevent the dirt impurities from circulating with the cleaning liquid through the return water pipe 180 and entering the inner cavity of the radiator 100.

[0089] Please refer to Fig.17The radiator cavity pollution treatment and inspection method of this embodiment is implemented based on a radiator cavity pollution treatment and inspection device provided in this embodiment. In the early stage of the cavity cleaning process of the radiator 100, a cleaning liquid circulation cleaning method is adopted, and in the later stage, a liquid-gas two-phase vibration cleaning method is adopted. Industrial pure water can be used for rinsing in the cavity rinsing process of the radiator 100. The cleaning liquid can be prepared by mixing a cleaning agent and industrial pure water in a preset ratio, and the cleaning liquid can be a neutral cleaning liquid. The cleaning liquid reacts with the oil substance in the cavity of the radiator 100 and emulsifies and dissolves it. The dirt obtained after it is peeled off from the side wall of the cavity of the radiator 100 by water flow flows out of the radiator 100 with the water flow.

[0090] Please refer to Figures 1 to 12 The radiator inner cavity contamination treatment and inspection equipment of this embodiment, by providing an inner cavity cleaning and contamination detection device 1 with cleaning and rinsing functions, enables the radiator 100 to be cleaned and rinsed in the same area, thereby reducing the number of times the radiator 100 is lifted.

[0091] Please refer to Fig.17 The radiator inner cavity pollution treatment and inspection method of the present embodiment can be combined with the circulation cleaning of the cleaning liquid and the two-phase vibration cleaning of the liquid-gas mixed fluid, and combined with the clean water rinsing, which is beneficial to remove the dirt in the dead corners of the inner cavity of the radiator 100, improve the cleaning effect and efficiency of the inner cavity of the radiator 100, reduce the cleaning time, and improve work efficiency; and can reduce the water consumption, reduce the use of corresponding pipelines and valves, reduce costs, and save environmental protection.

[0092] Please refer to Fig.18 In some embodiments, the radiator cavity pollution treatment and inspection method of this embodiment, after the liquid-gas two-phase oscillation cleaning in step S23, first perform the following step S24, and then perform the step S31 of connecting the rinsing water tank:

[0093] Step S24, cleaning liquid reflux: close the outlet valve 171, open the air inlet valve 171, so that high-pressure air enters the inner cavity of the cleaning pipe 140 and the radiator 100, so that the cleaning liquid in the cleaning pipe 140, the inner cavity of the radiator 100 and the return pipe 150 flows back to the cleaning water tank 110.

[0094] By opening the air intake valve 171, high-pressure air is forced to fill the inner cavity of the cleaning pipe 140 and the radiator 100, so that the cleaning liquid in the cleaning pipe 140, the inner cavity of the radiator 100 and the return pipe 150 flows back to the cleaning water tank 110, reducing the retained amount of cleaning liquid in the inner cavity of the cleaning pipe 140 and the radiator 100, which is beneficial to improving the rinsing effect and rinsing efficiency of the inner cavity of the subsequent radiator 100.

[0095] It should be noted that in the step of reflowing the cleaning liquid, the air inlet valve 171 can be fully opened to force a large flow of high-pressure air to quickly enter the inner cavity of the cleaning pipe 140 and the radiator 100, so that the cleaning liquid in the cleaning pipe 140, the inner cavity of the radiator 100 and the return pipe 150 can quickly flow back to the cleaning water tank 110.

[0096] In addition, during the step of backflow of the cleaning liquid, the water outlet valve 171 is in a closed state;

[0097] Please refer to Figures 1 to 8 and Fig.13 In some embodiments, the above-mentioned radiator inner cavity pollution treatment and inspection equipment is provided with an inner cavity drying device 2, the inner cavity drying device 2 is provided with a hot air blower 210, the hot air blower 210 is provided with an air outlet 2101, the air outlet 2101 is connected to one end of the high temperature resistant pipeline 220, and the other end of the high temperature resistant pipeline 220 is used to connect to the inner cavity inlet 101 of the radiator 100.

[0098] Please refer to Fig.18 In the above-mentioned radiator cavity pollution treatment and inspection method, in the contamination inspection step, if the residual contaminants meet the requirements, a drying stage is performed; the drying stage includes the following steps:

[0099] Step S51, inner cavity drying: connect the other end of the high temperature resistant pipe 220 to the inner cavity inlet 101 of the radiator 100, turn on the hot air blower 210, so that hot air enters the inner cavity of the radiator 100 through the air outlet 2101 of the hot air blower 210, the high temperature resistant pipe 220 and the inner cavity inlet 101 for drying. At this time, the inner cavity outlet 102 of the radiator 100 can be connected to the outside atmosphere.

[0100] The radiator inner cavity contamination treatment and inspection equipment and method of the present embodiment dries the inner cavity of the radiator 100 after cleaning and rinsing through the inner cavity drying device 2, so that the inner cavity of the radiator 100 remains dry, avoiding the retention of moisture in the inner cavity of the radiator 100 that affects the use, thereby facilitating the subsequent normal and safe use of the radiator 100; and hot air is sent to the inner cavity of the radiator 100 for drying through the hot air blower 210, which is beneficial to quickly drying a large area of ​​water distributed in the inner cavity of the radiator 100, thereby improving production efficiency.

[0101] Please refer to Figure 1 , Fig.14 and Fig.15In some embodiments, the above-mentioned radiator inner cavity pollution treatment and inspection equipment is provided with a water-gas separation box 3, which includes a water tank 310, a baffle 320 and a partition 330; the partition 330 is installed in the water tank 310, and the partition 330 is provided with a water hole 331; the baffle 320 is installed in the water tank 310, and the upper part of the baffle 320 is obliquely arranged above the baffle 330; the water tank 310 is provided with an air inlet 311 and a water outlet 312, the air inlet 311 is arranged between the upper part of the baffle 330 and the baffle 320, and the water outlet 312 is arranged at the lower part of the water tank 310; the air inlet 311 is connected to one end of the exhaust pipe 313, and the other end of the exhaust pipe 313 is used to connect to the inner cavity outlet 102 of the radiator 100; the water outlet 312 is connected to the first sewage pipe 314.

At this time, the water suction pipeline 160, the cleaning pump 130, the water outlet pipeline 170, and the inner cavity of the radiator 100 to the water return pipeline 180 remain unobstructed, and the water suction valve 164 on the water suction pipeline 160 and the water return valve 185 on the water return pipeline 180 are both in an open state; wherein the water suction valve 164 and the water return valve 185 are configured as manual valves; manually open the water outlet valve 171 on the water outlet pipeline 170 connected to the water outlet of the cleaning pump 130, start the cleaning pump 130, and use the cleaning The cleaning liquid in the washing water tank 110 circulates and cleans the inner cavity of the radiator 100 for a preset time; the circulation path of the cleaning liquid is: the washing water tank 110, the water suction pipeline 160 (including the water suction branch pipe 162 and the water suction main pipe 163), the cleaning pump 130, the water outlet valve 171, the water outlet pipeline 170, the cleaning pipe 140, the inner cavity inlet 101 of the radiator 100, the inner cavity of the radiator 100, the inner cavity outlet 102 of the radiator 100, the return water pipeline 180 (including the return water branch pipe 181, the return water branch pipe 182, the return water branch pipe 183, the return water branch pipe 184, the return water branch pipe 185, the return water branch pipe 186, the return water branch pipe 187, the return water branch pipe 188, the return water branch pipe 189, the return water branch pipe 190, the return water branch pipe 191, the return water branch pipe 192, the return water branch pipe 193, the return water branch pipe 194, the return water branch pipe 195, the return water branch pipe 196, the return water branch pipe 197, the return water branch pipe 198, the return water branch pipe 199, the return water branch pipe 191, the return water branch pipe 197, the return water branch pipe 198, the return water branch pipe 199, the return water branch pipe 199, the return water branch pipe 191, the return water branch pipe 199, the return water branch pipe 191, the return water branch pipe 192, the return water branch pipe 193, the return water branch pipe 194, the return water branch pipe 195, the return water branch pipe 196, the return water branch pipe 198 pipe 183 and return water main pipe 184) and cleaning water tank 110; when the cleaning liquid flows through the filtering structure formed by multiple small holes on the water suction branch pipe 162, it prevents foreign matter with larger particles from entering the cleaning pump 130 and damaging the components of the cleaning pump 130; after the cleaning liquid flows through the outlet filter 173, the impurities that may exist in the cleaning liquid are first filtered, and then flow into the inner cavity of the radiator 100 through the cleaning pipe 140; the cleaning liquid is set to be a neutral cleaning agent and water prepared in a preset ratio, the cleaning liquid reacts with the oil substances in the inner cavity of the radiator 100, emulsifies and dissolves it, and uses the water flow to peel it off from the inner cavity side wall of the radiator 100, and then flows out of the radiator 100 with the water flow; after the cleaning liquid flows through the return water filter 181, the impurities therein are filtered out to prevent the cleaned impurities from entering the inner cavity of the radiator 100 for a second time. The cleaning time is set according to the volume of the radiator 100, the type of cooling medium, and the degree of contamination, and is generally not less than 30 minutes;

[0162] Secondly, the inner cavity of the radiator 100 is cleaned by liquid-gas two-phase vibration; the cleaning pump 130 is kept running, the air inlet valve 172 on the outlet pipe 170 of the cleaning pump 130 is opened, and compressed air with a pressure higher than the pipe water pressure is rushed into the outlet pipe 170 to form a mixed state of gas and liquid; the opening degree (i.e., flow rate) of the air inlet valve 172 should not be too large, so that obvious fluctuations can be seen in the cleaning pipe 140; since the air inlet pressure is higher than the water pressure in the pipe, but the flow rate is small, the high-pressure compressed air interferes with the flow of the cleaning liquid, forming an intermittent oscillation phenomenon; this oscillation is conducive to stripping dirt and impurities from various parts of the inner cavity of the radiator 100, and the stripped dirt and impurities are discharged from the radiator 100 with the cleaning liquid and enter the return pipe 180; the main function of the oscillation cleaning is to accelerate the stripping and flow of dirt; after the preset oscillation cleaning time, the operation of the cleaning pump 130 is stopped, and the outlet valve 171 of the outlet pipe 170 of the cleaning pump 130 is closed at the same time;

[0163] Once again, drain the cleaning liquid; open the air inlet valve 172 to the fully open state, so that the compressed air quickly fills the water outlet pipe 170 and the inner cavity of the radiator 100, forcing the cleaning liquid in the water outlet pipe 170, the inner cavity of the radiator 100, and the return water pipe 180 to quickly flow back to the cleaning water tank 110, and at the same time, the cleaning liquid foam on the inner cavity side wall of the radiator 100 is blown and broken, thereby reducing the subsequent rinsing time; when there is no obvious water outflow at the return water port 195 of the cleaning water tank 110, close the air inlet valve 172; open the water outlet filter 173 and the return water filter 181 on the water outlet pipe 170 and the return water pipe 180 respectively, remove the metal filter screens of the two filters, rinse the metal filter screens with clean water, and then put them back into the water outlet filter 173 and the return water filter 181 respectively, and install the water outlet filter 173 and the return water filter 181 to restore them to their original state;

[0164] Then, the inner cavity of the radiator 100 is rinsed; the water suction electric reversing valve 161 and the water return electric reversing valve 182 on the water suction pipeline 160 and the water return pipeline 180 are respectively changed in direction by the cleaning controller; the water suction electric reversing valve 161 opens the water suction branch pipe 162 between the water suction main pipe 163 and the rinsing water tank 120, and the water return electric reversing valve 182 opens the water return branch pipe 183 between the water return main pipe 184 and the rinsing water tank 120; the inner cavity of the radiator 100 is rinsed in two steps:

[0165] The first step is to disconnect the return pipe 150 connected to the inner cavity outlet 102 of the radiator 100 from the return filter 181 on the return main pipe 184, and connect the return pipe 150 to the drainage pipe at the work site; start the cleaning pump 130, and use the clean water in the rinse water tank 120 to rinse the inner cavity of the radiator 100 for a preset time; the flow path of the rinse water is: the rinse water tank 120, the water suction pipeline 160 (including the water suction branch pipe 162 and the water suction main pipe 184) and the water suction branch pipe 162. The rinsing water tank 120 is provided with a plurality of cleaning liquids, and the cleaning pump 130 is provided with a plurality of cleaning liquids. The cleaning pump 130 is provided with a plurality of cleaning liquids, and the cleaning liquids are ...

[0166] The second step is to remove the return pipe 150 from the drainage pipe at the work site and reconnect it to the return filter 181 of the return main pipe 184; start the cleaning pump 130 again, and the water in the rinsing water tank 120 rinses the inner cavity of the radiator 100 through the above path, and then flows back to the rinsing water tank 120 after passing through the return pipe 150, the return filter 181, the return main pipe 184, and the return branch pipe 183; the rinsing time can be set according to the size of the radiator 100 and the degree of contamination of the inner cavity; after the preset rinsing time, turn off the cleaning pump 130;

[0167] Then, the inner cavity of the radiator 100 is checked for contamination; the return water filter 181 on the return water pipe 180 is opened, and the inlet side surface of the filter screen of the return water filter 181 is visually checked to ensure that no particles remain; the filter screen of the return water filter 181 can be set as a stainless steel filter screen; if there are particles remaining on the inlet side surface of the filter screen of the return water filter 181, the filter screen of the return water filter 181 is cleaned and then restored to the return water pipe 180, and the cleaning pump 130 is started to rinse the inner cavity of the radiator 100 again until the inlet side surface of the filter screen of the return water filter 181 meets the requirements by visual inspection, that is, no particles remain; when selecting the filtering accuracy of the filter screen of the return water filter 181, that is, the mesh size, it shall not be lower than the requirements for the cleanliness of the inner cavity of the radiator 100. For example, the diameter of particles in the inner cavity of the radiator 100 shall not be greater than 100 μm. After the inner cavity contamination level of the radiator 100 is checked to be qualified, the connection between the cleaning pipe 140 and the return pipe 150 and the radiator 100 is disconnected.

[0168] Then, the inner cavity of the radiator 100 is dried; the air outlet 2101 of the hot air blower 210 is connected to the inner cavity inlet 101 of the radiator 100 by a high temperature resistant pipe 220, and the high temperature resistant pipe 220 can be a high temperature resistant hose; the inner cavity outlet 102 of the radiator 100 is connected to the atmosphere, or connected to a preset exhaust port by a hose; the temperature of the air outlet 2101 of the hot air blower 210 is adjusted to a temperature above 100°C, but not higher than the maximum tolerable temperature of the radiator 100; if a seal is installed on the radiator 100, the maximum tolerable temperature of the seal should be considered; start the hot air blower 210, and the cold air is discharged from the air outlet 2101 at a high speed through the air inlet 215, the centrifugal fan, and the heater 211 of the hot air blower 210. The centrifugal fan pressurizes the inhaled air, and the heater 211 heats the air flowing through it to a specified temperature; the pressurized and heated hot air is sent to the inner cavity of the radiator 100 through the high-temperature resistant pipeline 220, and is quickly discharged from the inner cavity outlet 102 of the radiator 100; when the high-speed hot air passes through the inner cavity of the radiator 100, on the one hand, the internal accumulated water is blown out, and on the other hand, heat is exchanged with the radiator 100 to increase its temperature; the residual water in the radiator 100 and the evaporated water vapor are discharged with the hot air and sent to the water-gas separation box 3; the water-gas mixture is diverted in the water-gas separation box 3; a baffle 320 is set on the left side of the partition 330, and the right side of the partition 330 is connected to the water tank 310, and the upper part of the baffle 320 is relatively inclined to form a ridge shape; when the water-containing air encounters the inclined part upward along the baffle 320, it changes direction and flows downward, so that the water falls to the horizontally placed baffle 330 below due to gravity, and passes through the partition The water permeable holes 331 on the plate 330 flow into the water tank 310 below; most of the gas is discharged upward to the outside atmosphere, and a small amount of gas flows into the water tank 310 through the water permeable holes 331, and in the process of traveling along the labyrinth path formed by the path plate 332 in the water tank 310, it is preferentially discharged into the atmosphere along the exhaust holes on the baffle 320; the diverted water flows into the water tank 310 through the water permeable holes 331 on the partition 320, and flows into the water collecting tray 4 through the water outlet 312 of the water tank 310, and is discharged into the second sewage pipe 410 together with other liquids in the water collecting tray 4; the drying time can be set according to the size of the radiator 100 until no water is discharged from the inner cavity outlet 102 of the radiator 100; for the HX series electric locomotive composite radiator, this method of drying is generally sufficient for 1 to 2 hours; after the inner cavity of the radiator 100 is dried, the high temperature resistant hose of the high temperature resistant pipeline 220 is removed;

[0169] Finally, the inner cavity of the radiator 100 is inspected and protected; after the radiator 100 is cooled to room temperature, the inner cavity of the radiator 100 is inspected with an endoscope. After confirming that there is no foreign matter inside, a special protective cover is used to protect it to prevent foreign matter from entering; the radiator 100 is hung from the drying station 520, and subsequent work is carried out after marking; among them, the cleaning station 510 and the drying station 520 have the same function and can be interchanged. After the inner cavity of the radiator 100 on the cleaning station 510 is cleaned and tested as qualified, the drying operation can be carried out at the original cleaning station 510. Similarly, after the radiator 100 on the drying station 520 is transported away, the subsequent radiator 100 can be cleaned and tested at the original drying station 520.
