[0023] like Figures 1 to 5As shown, a furnace body 2 is installed on the upper surface of the bottom plate 1, a furnace cover 3 is arranged on the top of the furnace body 2, a motor 4 is installed on the upper surface of the furnace cover 3, the end of the output shaft of the motor 4 is connected to a connecting shaft 5, the end of the connecting shaft 5 penetrates to the lower side of the furnace cover 3 and is installed with a rectangular plate 6, when the motor 4 is started, the rectangular plate 6 can be driven to rotate through the connecting shaft 5. Side grooves 7 are provided on the outer surfaces of both sides of the rectangular plate 6, and a lifting block 8 is installed inside the side groove 7 through a reciprocating lifting mechanism 13, and the reciprocating lifting mechanism 13 is in transmission cooperation with the motor 4, when the motor 4 is started, the reciprocating lifting mechanism 13 can be driven to drive the lifting block 8 to reciprocate up and down.
[0024] Connecting sleeves 9 are installed on both upper and lower sides of the outer surface of the lifting block 8. An F-shaped brush plate 10 is inserted into the two connecting sleeves 9. The F-shaped brush plate 10 has two installation positions, which can improve its installation strength and avoid damage during the cleaning process. The bristles of the F-shaped brush plate 10 are in contact with the inner wall of the furnace body 2. Since the starting motor 4 can drive the F-shaped brush plate 10 to rotate to clean the inner wall of the furnace body 2, and the reciprocating lifting mechanism 13 can drive the F-shaped brush plate 10 to reciprocate up and down, which can avoid cleaning dead corners.
[0025] An installation mechanism 17 capable of quickly disassembling and assembling the F-shaped brush plate 10 is provided between the two connecting sleeves 9. The installation mechanism 17 facilitates the replacement of the F-shaped brush plate 10, so that the F-shaped brush plate 10 can have a good cleaning effect and improve the portability of the operation. A vacuum pump 11 is provided on the outside of the furnace body 2, and the vacuum pump 11 creates a vacuum condition inside the furnace body 2. Hydraulic cylinders 27 are installed on both sides of the upper surface of the bottom plate 1. The ends of the telescopic ends of the hydraulic cylinders 27 are connected to the furnace cover 3. By starting the hydraulic cylinder 27, the telescopic ends drive the furnace cover 3 to rise, and then the F-shaped brush plate 10 can be pulled out from the furnace body 2, so as to facilitate the replacement of the F-shaped brush plate 10 and facilitate the maintenance of the furnace body 2 and the reciprocating lifting mechanism 13.
[0026] The bottom of the furnace body 2 is a conical structure, and a drain pipe 12 is installed at the bottom of the furnace body 2. The design of the conical structure can prevent liquid from remaining inside the furnace body 2, thereby affecting subsequent use.
[0027] The reciprocating lifting mechanism 13 includes an inner gear ring 14 installed on the top wall of the furnace cover 3, and the inner gear ring 14 is coaxially arranged with the connecting shaft 5.

When the inner wall of the furnace body 2 is cleaned, the motor 4 is started to drive the connecting shaft 5 to The rectangular plate 6 rotates and drives the F-shaped brush plate 10 to rotate. Due to the meshing relationship between the gear 15 and the inner gear ring 14, the rectangular plate 6 can drive the reciprocating screw 16 to rotate during the rotation. Since the inner wall of the side groove 7 limits the lifting block 8, the lifting block 8 can reciprocate up and down along the surface of the reciprocating screw 16. Therefore, during the rotation of the F-shaped brush plate 10, it can reciprocate up and down to avoid the situation where the gaps between the bristles cause cleaning dead corners, thereby improving the cleaning effect.

When the F-shaped brush plate 10 is removed, the two push blocks 20 can be pressed at the same time. The two insertion rods 21 can be driven to be pulled out from the two insertion holes 22 at the same time, and then the F-shaped brush plate 10 can be directly pulled out from the connecting sleeve 9. When installing the F-shaped brush plate 10, the two push blocks 20 are also pressed to drive the two insertion rods 21 to retract inward, and then the two ends of the F-shaped brush plate 10 are respectively inserted into the two connecting sleeves 9, and then the push blocks 20 are released.

When cleaning the inner wall of the furnace body 2, the cleaning liquid can be pumped into the water inlet pipe 26 through an external water pump and sprayed on the inner wall of the furnace body 2 from the nozzle 25. Combined with the cleaning effect of the F-shaped brush plate 10, the cleaning effect of the inner wall of the furnace body 2 can be greatly improved, and the dirt can be completely removed.

In the process of rotation of the rectangular plate 6, due to the meshing relationship between the gear 15 and the inner gear ring 14, the reciprocating screw 16 rotates, and then drives the lifting block 8 to lift and reciprocate, and drives the F-shaped brush plate 10 to lift and reciprocate, so as to avoid the F-shaped brush plate 10 cleaning the inner wall of the furnace body 2 at a fixed angle, avoid the occurrence of dead corners, improve the cleaning effect, and thus can thoroughly remove dirt. When the bristles of the F-shaped brush plate 10 pass through When deformation occurs after long-term use and the cleaning effect is reduced, the hydraulic cylinder 27 can be started, and its telescopic end drives the furnace cover 3 to rise, and drives the F-shaped brush plate 10 to rise to the outside of the furnace body 2, and then presses the two push blocks 20 at the same time, drives the two insertion rods 21 to be pulled out from the two insertion holes 22 at the same time, and then the F-shaped brush plate 10 is pulled out from the connecting sleeve 9. When installing the F-shaped brush plate 10, the two push blocks 20 are also pressed to drive the two insertion rods 21 to retract inward, and then the two ends of the F-shaped brush plate 10 are respectively inserted into the two connecting sleeves 9, and then the push blocks 20 are released. The compressed spring 23 releases the elastic force, and the push blocks 20 can be pushed to drive the insertion rods 21 to be inserted into the insertion holes 22, thereby completing the rapid replacement of the F-shaped brush plate 10 and improving the portability of use. The distillation principle of this device is consistent with the comparative patent, and will not be elaborated here.
