[0025] The above-mentioned connecting component is used to connect the discharge port 1-2 and the liquid inlet 4-2. It includes a filter element 11. The filter element 11 includes a filter shell 11-1. A material inlet 11-2 is provided at the top of the filter shell 11-1, and a discharge port 11-3 is provided at the bottom of the filter shell 11-1.

[0026] In order to facilitate the stirring of the paint entering the tank body 1 so that the paint is evenly heated, a plurality of stirring components are provided on the tank body 1 and are transmitted to the rotating drum 4-3. The stirring components include a rotating rod 5 that passes through the top of the tank body 1 and is rotatable. The top end of the rotating rod 5 is connected to the rotating drum 4-3 through a gear transmission structure 8. The portion of the rotating rod 5 extending into the tank body 1 is located in the gap between the tank body 1 and the heating tube 3. A plurality of stirring blades 6 are provided on the rotating rod 5 located in the tank body 1.

[0027] When the filter element 11 is clogged, in order to promptly remind the staff, a bypass port 11 - 5 is provided on the side wall of the filter housing 11 - 1 , and a hydraulic monitoring component 13 is provided at the bypass port 11 - 5 .

[0028] The above-mentioned hydraulic monitoring component 13 includes a main shell 13-1, and a connecting port 13-2 threadedly connected to the bypass port 11-5 is provided on the side of the main shell 13-1. A piston plate 13-3 is slidably provided in the main shell 13-1. An elastic rod 13-4 is also provided in the main shell 13-1 to apply a thrust to the piston plate 13-3 toward the connecting port 13-2. A contact switch 13-5 for the corresponding solenoid valve 9 and electrically connected to the controller 14 is also provided in the main shell 13-1. An exhaust port 13-7 is provided on the side of the main shell 13-1.

[0029] In order to ensure the heating efficiency between the friction strip 4-11 and the heating tube 3 and to avoid heat loss as much as possible, the heating tube 3 is made of chrome copper; the sliding rod 4-9 is made of ceramic; the friction strip 4-11 is made of titanium alloy or aluminum alloy. In addition, the outer surface of the rotating drum 4-3 located in the tank body 1 is provided with a ceramic coating to further prevent heat loss.

[0030] In order to prevent the paint from adhering to the inner wall of the tank body 1 or the outer wall of the heating tube 3 , the inner wall of the tank body 1 and the outer wall of the heating tube 3 are coated with nano self-cleaning coating.

[0031] In order to ensure the stable rotation of the adjusting rod 4-6, a guide plate 4-12 for the adjusting rod 4-6 is provided in the rotating drum 4-3.

[0032] In order to prevent the adjusting rod 4-6 from rotating randomly, a butterfly bolt 4-14 is threaded through the rotating drum 4-3. The end of the butterfly bolt 4-14 is connected to a pressure plate 4-15 for the adjusting rod 4-6 through a rotating joint. The pressure plate 4-15 is covered with rubber to prevent the adjusting rod 4-6 from being damaged.

[0033] It should be noted that a section of thread is provided on the adjusting rod 4-6 for screwing connection with the rotating cylinder 4-3, so as to facilitate adjusting the length of the adjusting rod 4-6 entering the rotating cylinder 4-3, thereby adjusting the distance that the pushing head 4-7 pushes the sliding rod 4-9 outwards, and further changing the extrusion degree of the elastic telescopic rod 4-10, so as to change the frictional force between the friction strip 4-11 and the heating cylinder 3.

[0034] The specific working principle of the present invention is as follows: First, adjust the position of the adjusting rod 4-6 according to the type of paint, and then change the frictional force between the friction strip 4-11 and the heating cylinder 3 to change the calorific value of the heating cylinder 3. Then, start the delivery pump 2 and the solenoid valve 9 at one of the discharge ports 1-2 through the controller 14. The paint is delivered into the tank body 1 and then discharged from the discharge port 1-2 and enters the filter element 11 through the connecting cylinder 10. After being filtered by the filter screen 11-4, the impurities are blocked by the filter screen 11-4, and then the paint is discharged from the discharge port 11-3 and enters the shell 4-1 through the connecting cylinder 2 and the connecting pipe 12. The paint pushes the fan blade 4-4 to make the rotating cylinder 4-3 rotate, and then the paint is discharged from the liquid outlet 4-5; in addition, when the rotating cylinder 4-3 rotates, the sliding rod 4-9 and the elastic telescopic rod 4-10 also rotate, so that friction heat is generated between the friction strip 4-11 and the heating cylinder 3, and the generated heat heats the paint to increase the fluidity of the paint and accelerate the filtering efficiency of the paint.

[0035] When the filter screen 11-4 is blocked, the paint in the filter housing 11-1 enters the main housing 13-1 from the bypass port 11-5 and pushes the piston plate 13-3 to move. When the piston plate 13-3 touches the contact switch 13-5, the controller 14 closes the solenoid valve 9 and opens the solenoid valve 9 at the other discharge port 1-2. At the same time, the controller 14 issues an alarm to remind the staff to repair the filter element 11.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present invention or make equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
