[0039] S2, the slag and the cleaning liquid cleaned by the cleaning mechanism 3 are sucked into the interior of the push shovel 6 by the suction gun assembly 15, and the large particles of slag entering the push shovel 6 are crushed into small particles by the crushing mechanism 5, and then enter the interior of the slag cleaning cylinder 4;

[0040] S3. Use the grinding wheel 8 to grind the slag into powder until it meets the standard of passing through the through hole 71 on the partition 7. Then, the waste liquid containing the slag powder is discharged into the waste barrel 11 through the No. 2 hard feed pipe 12 and the No. 2 delivery hose 13 through the suction gun assembly 15.

[0041] The cleaning and drainage equipment includes a moving frame 1 and a horizontal furnace tube body 2, and also includes a cleaning mechanism 3, which is arranged on the moving frame 1 and is used to clean the inner wall of the slag cleaning cylinder 4; the slag cleaning cylinder 4 is installed on the cleaning mechanism 3, and a push shovel 6 is connected to the slag cleaning cylinder 4, and a crushing mechanism 5 is arranged on the push shovel 6; wherein the crushing mechanism 5 includes a No. 1 driving motor 51 detachably mounted on the push shovel 6 and a protective shell 54 fixedly mounted on the push shovel 6, a driving gear 52 is fixedly mounted on the output end of the No. 1 driving motor 51, and a plurality of rotating shafts 55 that are equidistant and arranged in parallel are rotatably mounted on the protective shell 54, each rotating shaft 55 is fixedly mounted with a driven gear 53 arranged inside the protective shell 54, and the plurality of driven gears 53 are meshingly connected, the driving gear 52 is meshingly connected with the uppermost driven gear 53, and a crushing roller 56 is fixedly mounted on each rotating shaft 55.

[0042] Specifically, after the slag is washed off the inner wall of the horizontal furnace tube and before the suction gun assembly sucks the slag into the push shovel, the No. 1 driving motor 51 is started to drive the driving gear 52 to rotate, and the driving gear 52 drives the uppermost driven gear 53 among the multiple driven gears 53 to rotate, and then all the driven gears 53 are driven to rotate through the uppermost driven gear 53, and the rotation directions of two adjacent driven gears 53 are opposite, thereby driving the crushing roller 56 to rotate, crushing large pieces of slag into the interior of the slag cleaning tube 4, which can reduce the occupied area inside the slag cleaning tube 4 on the one hand, and the small slag after crushing will not block the through hole 71 on the partition 7, affecting the normal flow of airflow, and thus affecting the automatic drainage after cleaning.

[0043] In this embodiment, a suction gun assembly 15 is provided through the slag cleaning barrel 4, a No. 2 conveying hose 13 is connected through the suction gun assembly 15, and a waste bucket 11 is provided on the mobile frame 1, and one end of the No. 2 conveying hose 13 away from the suction gun assembly 15 is inserted into the interior of the waste bucket 11.

[0044] Specifically, by starting the suction gun assembly 15, which is a prior art, the cleaned slag and cleaning liquid are sucked into the interior of the shovel 6 through strong wind force, and the waste cleaning liquid enters the interior of the slag cleaning cylinder 4 and passes through the through hole 71 on the partition 7 from the interior of the No. 2 hard feed pipe 12 and the No. 2 conveying hose 13 into the interior of the waste bucket 11, thereby realizing the automatic discharge of the cleansing liquid after washing.

During the cleaning process, the cleaning mechanism 3 can drive the No. 1 hard feed pipe 35 to rotate all the time, and the slag crushed into small-caliber by the crushing mechanism 5 enters the interior of the slag cleaning cylinder 4. Moreover, the rotation of the No. 1 hard feed pipe 35 can drive the grinding wheel 8 inside the slag cleaning cylinder 4 to rotate, and the raised part of the grinding wheel 8 continuously grinds the crushed small-caliber slag into the slag cleaning cylinder 4. The slag blocks are squeezed into powder again until the radius of the particles is smaller than the diameter of the through hole 71 on the partition 7, and the slag powder can be automatically discharged through the cleaning liquid to avoid excessive accumulation inside the slag cleaning cylinder 4, which affects the normal use of the cleaning and drainage equipment. A limiting shaft 14 is slidably installed on the connecting plate 17, and the end of the limiting shaft 14 away from the connecting plate 17 is fixedly installed with the slag cleaning cylinder 4, which can prevent the slag cleaning cylinder 4 from rotating inside the horizontal furnace tube body, and the grinding wheel 8 is arranged inside the slag cleaning cylinder 4, and a partition 7 is installed at the gap between the slag cleaning cylinder 4 and the grinding wheel 8, and the partition 7 is provided with a through hole 71 to allow powdered slag to pass through.

At the same time, the No. 1 hard feed pipe 35 is driven to rotate by starting the No. 2 driving motor 9, and the No. 1 hard feed pipe 35 drives the hollow rotating disk 39 to rotate, and the hollow rotating disk 39 drives the brush 310 to scrub the inner wall of the horizontal furnace tube body 2, and the liquid stuck on the inner wall of the horizontal furnace tube body 2 is scrubbed off.

[0051] On the basis of this embodiment, an electric push rod 10 is fixedly installed on the mobile frame 1, and a connecting plate 17 is fixedly installed on the output end of the electric push rod 10. The height of the connecting plate 17 is adjusted by the electric push rod 10, and the connecting plate 17 drives the cleaning mechanism 3 thereon to align with the horizontal furnace tube body 2 facing the inlet. A No. 2 driving motor 9 for driving a No. 1 hard feed pipe 35 to rotate is provided on the connecting plate 17. Four running wheels 16 are provided at the lower end of the mobile frame 1, which are used to drive the cleaning and drainage equipment thereon to move inside the horizontal furnace tube body 2 by pushing the mobile frame 1 to clean different parts of the inner wall of the horizontal furnace tube body 2. After the discarded cleaning liquid and slag are cleaned out, the delivery pump 32 above the liquid storage box 31 filled with alcohol solution is started to pump alcohol into the interior of the liquid supply box 34, and the alcohol is sprayed out through the liquid spray port 311 on the hollow rotating disk 39 to accelerate the drying of the inner wall of the horizontal furnace tube body 2.
