When the liquid level of the residual liquid reaches the standard, the bottom heating mechanism 3 and the radial heating plate 411 start to heat the barrel 21. The fourth temperature sensor 54 can detect the steam temperature at the top of the barrel 21 and adjust the temperature of the radial heating plate 411 according to the detection result to improve the heating efficiency.

[0055] Specifically, as shown in Figure 9 The top cover is provided with a liquid inlet flange, a gas outlet flange, a temperature sensor flange, a liquid level meter flange, which pass through the top cover insulation layer 53 to communicate with the barrel 21, to connect the liquid inlet pipeline 23, the steam filter pipeline 22, the fourth temperature sensor 54 and the liquid level meter 55. A liquid level switch flange can also be arranged to connect the liquid level switch 56. When the liquid level meter 55 cannot work, the residual liquid continues to enter the barrel 21. When the liquid level of the residual liquid is too high, the residual liquid touches the liquid level switch 56 to stop the liquid from entering, preventing the residual liquid in the barrel from overflowing.

[0056] Alternatively, as shown in Figure 1 and Figure 9As shown, the drying device for treating residual liquid also includes a top cover drive mechanism 9. The top cover drive mechanism 9 includes a top cover cylinder 92, a support rod 93, a connecting seat 94, and a guide column 95. The support rod 93 is perpendicular to the column 11 and connected to the bracket 1. The two support rods 93 are respectively connected to the two ends of the connecting seat 94. The connecting seat 94 has a through hole and a guide hole along its vertical direction. The top cover cylinder 92 passes through the through hole. The fixed end of the top cover cylinder 92 is connected to the connecting seat 94. The telescopic end of the top cover cylinder 92 is drivenly connected to the top cover mechanism 5. The guide column 95 passes through the guide hole. One end of the guide column 95 is connected to the top cover mechanism 5.

[0057] In this embodiment, the telescopic end of the top cover cylinder 92 is connected to the top cover. A through hole is provided on the connecting seat 94. The connecting seat 94 is sleeved on the fixed end of the top cover cylinder 92 through the through hole and bolted to the top cover mechanism 5. The connecting seat 94 is also provided with guide holes. The two guide holes are opened in the same direction as the through hole and are located on both sides of the through hole. A guide post 95 is provided in each guide hole. One end of the guide post 95 is connected to the top cover mechanism 5. Support rods 93 are bolted to both sides of the connecting seat 94 in the direction perpendicular to the guide hole. The two ends of the two support rods 93 are fixedly connected to the bracket 1. That is, the connecting seat 94, the fixed end of the top cover cylinder 92 and the support rods 93 are connected to the bracket 1 as a whole. The telescopic end of the top cover cylinder 92 moves in the vertical direction, which can drive the top cover mechanism 5 to move in the vertical direction, so that the top cover mechanism 5 covers the barrel body 21. The guide post 95 provides a guiding function for the telescopic end of the top cover cylinder 92, making the movement of the top cover mechanism 5 more stable.

[0058] Optionally, such as Figure 1 As shown, the drying device for treating residual liquid also includes a spring balancer 91, which is vertically disposed above the top cover mechanism 5. One end of the spring balancer 91 is connected to the bracket 1, and the other end is connected to the upper surface of the top cover mechanism 5.

[0059] In this embodiment, a spring balancer 91 is set in the vertical direction. The spring balancer 91 is located above the top cover mechanism 5. One end of the spring balancer 91 is connected to the bracket 1, and the other end can be connected to the top cover mechanism 5 through the lifting ring set on the top cover mechanism 5. When working, the force of the top cover cylinder 92 to the top cover mechanism 5 can offset the force of the spring balancer 91. When the drying device is powered off or the top cover cylinder 92 is damaged, the top cover mechanism 5 can move upward under the action of the spring balancer 91 and detach from the barrel 21, so that the barrel 21 can be moved away.

[0060] Specifically, there are two spring balancers 91, which are respectively arranged on both sides of the top cover mechanism 5 relative to the top cover drive mechanism 9, so that the top cover mechanism 5 moves more smoothly.

[0061] Optionally, such as Figure 1 As shown, the drying device for treating residual liquid also includes a steam filter pipe 22, which is connected to the air outlet 58. The steam filter pipe 22 is equipped with a filter 221, a first temperature sensor 222, a steam pneumatic ball valve 223, and a steam manual ball valve 224. The first temperature sensor 222 is used to detect the temperature of the steam. The steam pneumatic ball valve 223 is connected between the filter 221 and the air outlet 58. The steam manual ball valve 224 is connected to the outlet of the filter 221.

[0062] In this embodiment, a steam filter pipe 22 is provided, which is connected to the air outlet 58 on the top cover mechanism 5. A first temperature sensor 222 is provided on the steam filter pipe 22 near the air outlet 58 to detect whether the steam temperature meets the standard. The bottom heating mechanism 3 and the heating plate assembly 41 can be adjusted according to the detection result. A filter 221 is also provided on the steam filter pipe 22. The filter 221 includes upper and lower parts connected by bolts. A demister is provided in the filter 221 to filter the steam discharged from the barrel 21. A steam pneumatic ball valve 223 is provided between the filter 221 and the air outlet 58. The operation of the filter 221 can be controlled by controlling the opening and closing of the steam pneumatic ball valve 223. A steam manual ball valve 224 is provided at the outlet of the filter 221 to facilitate the maintenance of the filter 221.

[0063] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
