A sealed circular cavity 502 is formed inside the turntable housing. A liquid inlet 505 and a liquid return port 506 are provided at the bottom of the turntable housing. A coaxial ball-serving disc is provided in the circular cavity. The ball-serving disc is positioned in the circular cavity by the rotating shaft and rotates. One end of the rotating shaft is sealed and extends out of the bottom surface of the turntable housing. The ball-serving disc is evenly spaced along the circumference of the disc surface with ball-serving barrels 509. The bottom of the ball-serving barrel is a liquid inlet with a gradually smaller diameter, which is connected to the circular cavity in the turntable housing. The top of the ball-serving barrel is a ball-serving port. The top surface of the turntable housing is provided with a ball-adding hole 504 and a ball-liquid outlet 503 which are connected to the ball-serving port when the ball-serving disc rotates. The ball-adding hole is connected to a detachable gland to form a seal.

The liquid return port of the turntable serving mechanism is connected to the top of the degreasing liquid tank 2 through a pipeline with a control valve B15 and a diaphragm pump 16.

[0026] The pipeline connected to the rinse joint A11 in the rinse device branches into two paths, one of which is connected to the outlet of the second pump 20 through a pipeline with a control valve C21 and a manual switch valve 19, and the other is connected to the outlet of the air heater 24 through a pipeline with a control valve E25. The inlet of the air heater is connected to the air supply source, which is an air compressor or an air pump; the rinse joint B12 is connected to the top of the rinse liquid tank 3 through a pipeline. In order to realize the function of coil pressure testing, the pipeline connected to the rinse joint A is provided with a pressure test gauge, and the pipeline connected to the rinse joint B is provided with a control valve D23. By turning on the second pump and closing the control valve D, the pressure test inside the coil is realized. Furthermore, in order to improve the drying effect of the coil, a drying ball collecting cylinder 22 is provided in the pipeline where the above-mentioned rinsing joint B is located, and a drying ball issuing cylinder is integrated with the air heater. Sponge balls are placed in the drying ball issuing cylinder, and the sponge balls dry the inner wall of the coil together with the dry airflow. The dried sponge balls are collected in the drying ball collecting cylinder. An openable sealing cover is provided on the top of the drying ball collecting cylinder to facilitate the removal of the drying balls for repeated use.

[0027] The above-mentioned degreasing and cleaning device may also be provided with a purge structure, specifically: an air intake valve is provided on the liquid supply pipeline, and the air intake valve is externally connected to an air supply source, which is an air compressor or an air pump.

[0028] The working method of the containerized coil cleaning machine is as follows: first, the controller turns on the motor in the turntable ball-serving mechanism 5, and the motor drives the ball-serving disc 508 in the turntable housing 501 to rotate, and cleaning balls are added into the ball-serving barrel 509 of the ball-serving disc through the ball-adding hole 504 of the turntable housing, until all the ball-serving barrels of the ball-serving disc are filled with cleaning balls, and after the ball-adding is completed, a pressure cover is connected through the ball-adding hole to form a closure. Then, the pipe openings at both ends of the coil 26 to be cleaned are sealed and connected to the degreasing joint A8 and the degreasing joint B10 respectively, and the controller starts the first pump 13 and the control valve A14, and controls the reversing valve A7 and the reversing valve B9 to switch regularly. At this time, the degreasing liquid in the degreasing liquid tank 2 enters the turntable box along the liquid inlet pipeline under the action of the first pump. With the fixed-angle rotation of the ball-serving disc, the degreasing liquid pushes the cleaning balls of the ball-serving cylinder along the liquid supply pipeline 6 into the coil, realizing the degreasing cleaning of the inner wall of the coil, and with the switching of the reversing valve A and the reversing valve B, the direction of the fluid in the tube in the disc is switched, that is, a reciprocating cycle cleaning is formed, and the cleaned cleaning balls are sent to the degreasing ball collecting cylinder 4, and the degreasing liquid flows back to the degreasing liquid tank. When the degreasing cleaning is completed, close the control valve A, open the control valve B15 and the diaphragm pump 16, and use the diaphragm pump to return the excess degreasing liquid in the turntable box and the coil to the degreasing liquid tank through the pipeline connected to the return port 506. After the degreasing liquid is returned, close the control valve B and the diaphragm pump, open the air supply source and the air inlet valve 601, and introduce compressed air into the liquid supply pipeline. The compressed air forms a purge in the coil, and the residual degreasing liquid in the coil is purged into the degreasing liquid tank to ensure that there is no obvious residue in the coil. The above is to complete the degreasing cleaning operation. Next, separate the two ends of the coil from the degreasing joint A and the degreasing joint B, and connect them to the rinsing joint A11 and the rinsing joint B12, turn on the second pump 20, the control valve C21 and the control valve D23, close the control valve E25, and the rinsing liquid enters the coil for rinsing operation. The rinse liquid after rinsing flows back to the rinse liquid tank to form a circulating rinse. When the rinsing is completed, the second pump, control valve C and control valve D can be turned off, and control valve E, air heater 24 and air supply source can be turned on to form a purge and dry operation in the coil. After the coil is dried, the machine can be shut down and the pipe can be unloaded. During the above rinsing process, the pressure test operation in the coil can also be carried out, that is, the second pump and control valve C are turned on, and control valve D and control valve E are closed to carry out the pressure test in the coil, and the pressure status can be checked through the pressure test gauge.
