A mounting groove 605 is provided on the front of the drying box 602, and fixing grooves 607 are provided on both sides of the front of the drying box 602 above the mounting groove 605. Both sides of the top wall of the fixing groove 607 are fixedly connected to mounting springs 608. The bottom end of the mounting spring 608 is fixedly connected to a sliding block 609. One end of the bottom end of the sliding block 609 is fixedly connected to a positioning block 610. One side of the sliding block 609 is fixedly connected There is a pull rod 611, and the front of the drying box 602 is movably connected to the sealing plate 603. Positioning holes 606 are provided on both sides of the top of the sealing plate 603. The back of the sealing plate 603 is fixedly connected to a silica gel drying plate 604 extending to the inside of the drying box 602. The hot and humid air is discharged to the inside of the dehumidifier 601 through a one-way duct, and a large amount of moisture in the hot and humid air is removed by the dehumidifier 601, and then the silica gel drying plate 604 is used to dry and remove it again, so that the dried hot air is again transported to the inside of the shell 7 through the one-way duct. At the same time, after the drying operation is completed, the silica gel drying plate 604 can be taken out through the sealing plate 603, which is convenient for replacing the adsorption saturated silica gel drying plate 604 to ensure its good drying and dehumidification effect.

[0029] In this embodiment, a sliding structure is formed between one end of the sliding block 609 and the inside of the fixed groove 607. The shape of the fixed groove 607 and the sliding block 609 in the top view is convex.

The length of the inside of the positioning hole 606 is smaller than the length of one end of the inside of the fixing groove 607. The sealing plate 603 and the drying box 602 are installed and fixed by the snap-fit between the positioning block 610 and the inside of the positioning hole 606.

[0031] In this embodiment, scrapers 9 are fixedly connected to the upper ends of both sides of the surface of the stirring rod 11. The cross-section of the scraper 9 is in an inverted L shape. The inverted L-shaped scraper 9 is used to reduce the residue of the sulphur black semi-finished product on the inner wall of the shell 7.

By utilizing the spiral rod 16, when the stirring rod 11 rotates forward, the local sulfide black semi-finished product at the lower end of the shell 7 can be stirred to facilitate its drying. During subsequent discharge, the spiral rod 16 descends to the top of the discharge pipe 13, and then the stirring rod 11 rotates in the opposite direction to squeeze and transport the sulfide black semi-finished product downward, so that it can be discharged smoothly through the discharge pipe 13.

[0033] In this embodiment, limiting grooves 17 are provided on both sides of the fixed frame 8, and limiting blocks 18 are fixedly connected on both sides of the sliding plate 15 to slide with the inside of the limiting grooves 17. The sliding of the limiting blocks 18 in the limiting grooves 17 improves the stability of the sliding up and down sliding of the sliding plate 15.

[0034] Furthermore, a material guide platform 12 is fixedly connected to the inner bottom wall of the shell 7. The material guide platform 12 is funnel-shaped. The funnel-shaped material guide platform 12 is used to facilitate the guidance of the sulfide black semi-finished product, making it easier to discharge it through the discharge pipe 13.

[0035] In addition, the cross-section of the heating tube 14 is wavy, and the heating tube 14 is distributed at equal angles inside the heating sleeve 4. The wavy heating tube 14 is used to increase its heating area and reduce heating dead angles, thereby facilitating the heating and drying of the sulfur black semi-finished product inside the shell 7.

[0036] The working principle and use process of the utility model are as follows: first, the sulphur black semi-finished product is added to the interior of the shell 7 through the feed hopper 3, and then the heating tube 14 is started to heat the interior of the shell 7, and at the same time, the servo motor 2 is started to drive the stirring rod 11 to rotate, so that the scraper 9, the stirring blade 10 and the screw rod 16 rotate to stir the sulphur black semi-finished product inside the shell 7, and at the same time, the pneumatic telescopic rod 1 is started to drive the sliding plate 15 to slide up and down, thereby causing the scraper 9, the stirring blade 10 and the screw rod 16 to slide up and down, and the sulphur black semi-finished product inside the shell 7 is fully stirred to facilitate its more uniform drying;

[0037] The dehumidifier 601 is turned on and the hot and humid air is discharged to the inside of the dehumidifier 601 through the one-way duct. The dehumidifier 601 removes a large amount of moisture in the hot and humid air, and then transports it to the inside of the drying box 602. At this time, the silica gel drying plate 604 is used to dry and remove it again, so that the dried hot air is transported to the inside of the shell 7 through the one-way duct again, realizing waste heat recovery and recycling, avoiding the direct discharge of this part of the hot and humid air and causing heat waste. At the same time, after the drying operation is completed, the pull rod 611 can be toggled to drive the sliding block 609 to slide and compress the installation spring 608, thereby driving the positioning block 610 to completely disengage from the inside of the positioning hole 606. After that, the silica gel drying plate 604 can be taken out through the sealing plate 603, so that the saturated silica gel drying plate 604 can be replaced.

[0038] After the sulphur black semi-finished product is dried, the discharge pipe 13 is opened, and the guide platform 12 is used to guide the sulphur black semi-finished product to be discharged from the discharge pipe 13. At the same time, the pneumatic telescopic rod 1 is started to make the screw rod 16 descend to the upper end of the discharge pipe 13, and the servo motor 2 is started again to make the stirring rod 11 rotate in the opposite direction to drive the screw rod 16 to rotate in the opposite direction, and cooperate with the discharge pipe 13 to apply downward pressure on the sulphur black semi-finished product spiral, so that the sulphur black semi-finished product can be discharged from the discharge pipe 13 more stably and smoothly, thereby improving its discharge rate.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
