[0002] The pigment drying device is an important equipment for drying pigments. Usually, it adopts the drying method of a long cylindrical channel. The air is heated by an electric heating plate, and then the hot air is evenly blown onto the pigment mold in the drying channel by a blower to achieve uniform drying of the pigments. The transmission rack and the belt conveyor slowly move the mold filled with liquid pigments through the drying channel, so that the pigments are gradually dried into solids under the action of uniform hot air.
[0003] At present, there are some defects in the existing pigment drying devices on the market. For example, the liquid pigments expand when heated in the mold plate, and are easy to overflow and fall onto the belt of the belt conveyor. This situation will not only cause waste of pigments, but also may cause pigment residues to accumulate on the surface of the belt conveyor, affecting the transmission effect. If not cleaned for a long time, the pigment residues will gradually solidify, which may damage the equipment, reduce the service life of the equipment, and the frequent shutdown and cleaning work will also increase the maintenance cost and labor intensity, affecting the production efficiency.
[0004] Therefore, there is an urgent need for a pigment drying device with a cleaning function to solve the above technical defects. Content of the Utility Model

A cleaning mechanism is arranged inside the outlet 17; the cleaning mechanism includes a set of servo motors 19 fixedly connected to the rear end of the drying channel 1. The output shaft of the servo motor 19 is fixedly connected to a driving shaft 18. The driving shaft 18 extends into the drying channel 1 and is fixedly connected to a scraper 15. The scraper 15 is movably hinged to the inner wall of the drying channel 1. The scraper 15 is located right below the belt conveyor 10. A hanging rack 12 is fixedly connected to the right side of the bottom end of the transmission rack 9. A collection box 14 is hung at the hanging rack 12. Hanging grooves 13 are opened at both ends of the outer wall of the collection box 14. The hanging rack 12 is horizontally inserted into the hanging grooves 13. An inspection door 20 is arranged below the outlet 17;
[0025] Specifically, as Figure 1 and Figure 2 shown, a scraper 15 is arranged in the transmission outlet direction of the belt conveyor 10 of the drying device. After a period of drying operation, the servo motor 19 is started to drive the driving shaft 18 to rotate a certain angle, so that the front end of the scraper 15 abuts against the belt of the belt conveyor 10. When the conveyor is running without feeding, the caked pigments overflowing on the surface of the belt conveyor 10 can be scraped off, and the pigments fall into the collection box 14, avoiding damage to the device caused by the consolidation of pigments at the belt conveyor 10. After scraping off the pigments, the scraper 15 is turned over in the reverse direction, which does not affect the transmission of the belt conveyor 10. After opening the inspection door 20, the collection box 14 can be horizontally pulled out to pour out the pigments.
[0026] Embodiment 2: An automatic lifting mechanism is arranged outside the outlet 17; the automatic lifting mechanism includes a set of driving motors 23 fixedly connected to the lower right side of the outer wall of the drying channel 1. The output shaft of the driving motor 23 is fixedly connected to a threaded rod 24. A threaded sleeve 25 is sleeved outside the threaded rod 24. An outlet table 16 is welded to the threaded sleeve 25. A set of slideways 21 are opened at both ends of the outlet 17. A set of rollers 22 are arranged at both ends of the outlet table 16. The rollers 22 are in rolling connection in the slideways 21;
[0027] Specifically, as Figure 1 and Figure 3 shown, the pigment mold 8 transferred to the outlet 17 comes to the outlet table 16 under guidance. The driving motor 23 drives the threaded rod 24 to rotate, driving the threaded sleeve 25 to descend, thereby driving the outlet table 16 to descend. The two rollers 22 roll in the slideways 21 to ensure smooth movement, and can smoothly receive the descent of the pigment mold 8, facilitating the operator's taking.
[0028] Embodiment 3: Four groups of fans 4 are installed at the top of the drying channel 1, and each group of fans 4 is evenly distributed. An installation seat 2 is installed at the top of the inner wall of the drying channel 1, and an electric heating plate 3 is embedded in the installation seat 2. An electric heating pipe with a thermostat is installed in the electric heating plate 3. An electric control box 5 is installed on the left side wall of the drying channel 1, and the electric control box 5 controls the heating parameters. A fixing plate 6 is fixedly connected above the inner wall of the drying channel 1, and an air distribution plate 7 is horizontally fixed at the fixing plate 6. Uniform round holes are formed in the air distribution plate 7.
[0029] Specifically, as Figure 1 and Figure 4 shown, four groups of fans 4 are arranged at the top of the drying channel 1 to introduce air flow from the outside, and the heat generated by the electric heating plate 3 with constant temperature heating is blown towards the air distribution plate 7. After passing through the porous and uniform air flow in the air distribution plate 7, it is blown towards the pigment mold 8. During the transfer process of the pigment mold 8, the pigment is dried.
[0030] Working principle: The pigment mold 8 is placed into the drying channel 1 from the left inlet, and the belt conveyor 10 drives the pigment mold 8 to be transferred from left to right. Four groups of fans 4 are arranged at the top of the drying channel 1 to introduce air flow from the outside, and the heat generated by the electric heating plate 3 with constant temperature heating is blown towards the air distribution plate 7. After passing through the porous and uniform air flow in the air distribution plate 7, it is blown towards the pigment mold 8. During the transfer process of the pigment mold 8, the pigment is dried. The pigment mold 8 transferred to the discharge port 17 comes to the discharge table 16 under guidance. The driving motor 23 drives the threaded rod 24 to rotate, driving the threaded sleeve 25 to descend, thereby driving the discharge table 16 to descend. The two groups of rollers 22 roll in the slideway 21 to ensure smooth movement, and can smoothly receive the descent of the pigment mold 8, facilitating the operator to take it. When there is no material conveyed during the empty transfer, the servo motor 19 is started to drive the drive shaft 18 to rotate by a certain angle, so that the front end of the scraper 15 abuts against the belt of the belt conveyor 10, and the caked pigment overflowing on the surface of the belt conveyor 10 can be scraped off, causing the pigment to fall into the collection box 14, preventing the pigment from solidifying at the belt conveyor 10 and causing damage to the device. After scraping off the pigment, the scraper 15 is turned over in the reverse direction, which does not affect the transmission of the belt conveyor 10. After opening the inspection door 20, the collection box 14 can be horizontally pulled out to pour out the pigment.
