The air groove 9 and the exhaust fan 6 are arranged corresponding to each other. There are two groups of exhaust fans 6 and two air outlet pipes 7. One group of exhaust fans 6 is used in conjunction with one air outlet pipe 7. Through this arrangement, the waste residue or sludge can be fed into the drying shell 1 through the feeding and conveying main body 3, and then the electric heating wire 5 in the drying shell 1 is energized and heated. The heat of the electric heating wire 5 passes through the waste residue or sludge under the action of the exhaust fan 6, and the waste residue or sludge is heated and dried. At this time, the dust in the waste residue or the water vapor in the sludge will move upward under the action of the exhaust fan 6, and then be discharged through the air outlet pipe 7, so as to reduce the dust in the waste residue, and remove the water vapor in the sludge more quickly, reduce the impurities in the waste residue, and facilitate the drying of the sludge.

[0023] A connecting shell 10 is fixedly connected to the outer side of the right end of the conveying shell 2, a fixing plate 13 is arranged in the connecting shell 10, and sliding rods 11 are evenly distributed at the four corners of the fixing plate 13. The top of the sliding rod 11 is fixedly connected to the connecting shell 10, and the other end of the sliding rod 11 is fixedly connected to an anti-slip block 14. A spring 12 is arranged on the outer side of the end of the sliding rod 11 away from the anti-slip block 14, and a scraper 16 is evenly distributed and fixedly connected to the bottom of the fixing plate 13. The side of the scraper 16 away from the rubber block 15 is in contact with the feeding conveyor belt. There are two groups of rubber blocks 15 and scrapers 16, and the two groups of rubber blocks 15 and scrapers 16 are respectively arranged on the left and right sides of the bottom of the fixing plate 13, and the front one The rubber blocks 15 and the scrapers 16 of the group are staggered with the rubber blocks 15 and the scrapers 16 of the rear group. A crushing body 17 is provided at the right end of the bottom of the feeding conveying body 3, and a discharging conveying body 18 is provided directly below the crushing body 17. Through this arrangement, when the feeding conveying body 3 sends the dried sludge into the connecting shell 10, the spring 12 pushes the fixed plate 13 to move downward, and the fixed plate 13 pushes the rubber blocks 15 and the scrapers 16 to move downward. At this time, the rubber blocks 15 are slightly deformed by force, so that the bottom of the scraper 16 is in closer contact with the conveying shell 2, so that the sludge on the surface of the feeding conveying body 3 can be scraped off to prevent the sludge from sticking to the feeding conveying body 3.

[0024] Working process: When the mining and ore dressing waste sludge recycling device is used, firstly, the power is turned on, and then the feeding conveying body 3, the electric heating wire 5 and the exhaust fan 6 are started through the controller, and then the waste sludge or sludge is directly placed into the conveying shell 2 through the unloading trough 4 opened on the conveying shell 2. At this time, the waste sludge or sludge falls directly on the feeding conveying body 3 and is transmitted to the right through the feeding conveying body 3. At this time, the heat generated by the electric heating wire 5 flows upward under the action of the exhaust fan 6. When the heat passes through the waste sludge or sludge, the waste sludge or sludge is heated. At this time, the moisture in the sludge absorbs heat and evaporates, and the dust around the waste sludge is dried by heating. Then the exhaust fan 6 draws the water vapor or dust in the sludge into the air outlet pipe 7, and then the water vapor or dust is discharged through the air outlet pipe 7. The dried waste sludge or sludge It moves to the right in the conveying shell 2 and gradually enters the connecting shell 10 until the waste residue or sludge contacts the scraper 16. At this time, the fixed plate 13 is pushed downward on the outside of the slide rod 11 under the action of the spring 12. The fixed plate 13 pushes the rubber block 15 and the scraper 16 to move downward. At this time, the bottom of the scraper 16 contacts the feeding conveying body 3, and the sludge can be shoveled off the feeding conveyor belt. By setting up two sets of scrapers 16, the adhesion of the sludge to the feeding conveying body 3 can be reduced as much as possible. Then the waste residue or sludge passes through the connecting shell 10 and enters the crushing body 17. At this time, the crushing body 17 and the discharging conveying body 18 are started by the controller. After the large particles are crushed by the crushing body 17, they fall into the discharging conveying body 18, and finally the recovered waste residue or sludge is recovered by the discharging conveying body 18.
