[0009] The top of the drying section cover is provided with a feed pipe, which is connected to the discharge pipe at the bottom of the storage tank through a valve;

[0010] The drying section cover is provided with trays arranged at intervals from top to bottom. The trays are detachably connected to the drying section cover. Each tray has a notch that extends radially and penetrates the arc-shaped outer side plate. Except for the bottommost tray, each of the other trays has a funnel at its bottom. The upper opening of the funnel covers the upper tray, and its lower opening falls in the middle area of ​​the lower tray.

[0011] The drying section housing is equipped with a rotating shaft arranged from top to bottom. The rotating shaft is driven by a motor and passes through the lower opening of each funnel and the notch of the tray from top to bottom. A scraper is elastically installed on the rotating shaft along the axial direction for each tray, and the lower edge of the scraper abuts against the upper edge of the tray.

[0012] Furthermore, the tray includes an arc-shaped outer side plate, a U-shaped inner side plate, and a bottom plate. The U-shaped inner side plate is placed inside the arc-shaped outer side plate. The two ends of the U-shaped inner side plate are connected to the two ends of the arc-shaped outer side plate to form a circumferentially closed structure with openings at the top and bottom. The bottom plate is connected to the U-shaped inner side plate and the arc-shaped outer side plate and is used to enclose the lower opening of the area enclosed by the U-shaped inner side plate and the arc-shaped outer side plate.

[0013] Furthermore, a support sleeve is installed on the outer wall of the arc-shaped outer side plate. The support sleeve is fitted onto the pin, and the pin is fixedly connected to the inner wall of the drying section cover through a connecting frame.

[0014] Furthermore, a splicing block is inserted into the U-shaped inner side plate, and the end of the splicing block and the curved part of the U-shaped inner side plate form a perforated area for the rotating shaft to pass through.

[0015] Preferably, the straight sections on both sides of the U-shaped inner side plate are formed with concave grooves, and the two side walls of the splicing block are formed with convex guide ridges, which are inserted into the grooves.

[0016] A limiting strip is installed on the outer end of the splicing block, and a slot is provided on the limiting strip. A buckle is installed on the end of the arc-shaped outer plate, and the buckle engages with the slot.

[0023] This utility model provides a drying device for flame retardant production, which has the following beneficial effects: when the valve is opened, the storage tank feeds material into the top tray. During feeding, the scraper rotates and spreads the raw material evenly on the surface of the tray. When the material in the top tray is full, the feeding will continue to exceed the upper edge of its arc-shaped outer plate and fall off under the action of the scraper. The material is then collected by the funnel and falls into the lower tray. While achieving uniform spreading of raw materials and effective control of the stacking thickness, it also enables feeding material one by one between the upper and lower trays, which can reduce labor intensity.

[0060] The front and rear side panels of the drying section cover 5 are respectively equipped with flip-open doors 7, with a feed pipe on the top and an air outlet pipe 8 on the right side. The feed pipe is connected to the discharge pipe at the bottom of the storage tank through a valve 6. In some embodiments, the storage tank can be supported in a set of weighing sensors. The weighing sensors, valve 6 and PLC controller are electrically connected to achieve quantitative feeding. Alternatively, the storage capacity of the storage tank is the amount of material fed at one time. A vibration motor can be installed on the tank wall of the storage tank to improve the integrity of the material falling.

[0061] The drying section cover 5 is provided with trays 11 arranged at intervals from top to bottom. The trays 11 are detachably connected to the drying section cover 5. The trays 11 have a notch that extends radially and penetrates the arc-shaped outer side plate 11a. After the trays 11 are separated from the drying section cover 5, they can be moved along the notch to disengage from the rotating shaft 10 and be taken out. Except for the bottom tray 11, each of the other trays 11 has a funnel 13 at the bottom. A vibration motor can also be installed on the lower side wall of the funnel 13 to improve the material dropping effect. A collection tray can be set below the bottom tray 11 to collect the dropped raw materials. The upper opening of the funnel 13 covers the upper tray 11, and its lower opening 13a falls into the middle area of ​​the lower tray 11.

[0062] The drying section housing 5 is equipped with a rotating shaft 10 arranged from top to bottom. The top and bottom walls of the drying section housing 5 can be respectively equipped with bearing seats that cooperate with the rotating shaft 10. The rotating shaft 10 is driven by a motor 9, which is supported on a motor 9 support seat (not shown in the figure). The motor 9 support seat is connected to the frame 1 or the drying section housing 5. The rotating shaft 10 passes through the lower opening 13a of each funnel 13 and the notch of the tray 11 from top to bottom. A scraper 19 is elastically installed on the rotating shaft 10 along the axial direction for each tray 11. The lower edge of the scraper 19 abuts against the upper edge of the tray 11. The scraper 19 is connected to the rotating shaft 10 in a transmission connection. The motor 9 drives the rotating shaft 10 to rotate, thereby driving the scraper 19 to rotate and spread and level the raw materials.

[0063] In this embodiment, refer to the appendix. Figure 3 The tray 11 includes an arc-shaped outer side plate 11a, a U-shaped inner side plate 11c, and a bottom plate 11b. The U-shaped inner side plate 11c is placed inside the arc-shaped outer side plate 11a, and the internal area of ​​the U-shaped inner side plate 11c forms the U-shaped notch. The two ends of the U-shaped inner side plate 11c are connected to the two ends of the arc-shaped outer side plate 11a to form a circumferentially closed structure with openings at the top and bottom. The bottom plate 11b is connected to the U-shaped inner side plate 11c and the arc-shaped outer side plate 11a and is used to enclose the lower opening 13a of the area enclosed by the U-shaped inner side plate 11c and the arc-shaped outer side plate 11a. The bottom plate 11b can be provided with ventilation holes as needed, and the diameter of the ventilation holes should be smaller than the particle size of the raw material.

[0064] Among them, refer to the appendix Figure 3 A support sleeve 12 is installed on the outer wall of the arc-shaped outer side plate 11a. The support sleeve 12 is sleeved on the pin 22. The pin 22 is fixedly connected to the inner wall of the drying section cover 5 through the connecting frame 21. The tray 11 and the drying section cover 5 are detachably connected through the cooperation of the support sleeve 12, the pin 22 and the connecting frame 21.

[0065] In this design, a splicing block 14 is inserted into the U-shaped inner side plate 11c. The end of the splicing block 14 and the curved portion of the U-shaped inner side plate 11c form a perforated area through which the rotating shaft 10 passes. The upper edge of the splicing block 14 is flush with the upper edge of the U-shaped inner side plate 11c to reduce the amount of raw material falling through the notch. Preferably, the straight portions on both sides of the U-shaped inner side plate 11c have concave grooves, and the two side walls of the splicing block 14 have convex guide ridges. The guide ridges are inserted into the grooves (the guide ridges and grooves are not shown in the figure) to prevent the splicing block 14 from falling vertically. A limiting strip 15 is installed on the outer end of the splicing block 14. The limiting strip 15 has a latch 15a. A buckle 16 is installed on the end of the arc-shaped outer side plate 11a. The buckle 16 engages with the latch 15a to prevent the splicing block 14 from sliding out radially.

[0066] In this embodiment, a connecting sleeve is formed in the middle of the scraper 19. The connecting sleeve is axially movably sleeved on the rotating shaft 10. The rotating shaft 10 is provided with a spring 18 and a limiting sleeve 17 above the connecting sleeve, and a limiting bolt 20 below the connecting sleeve.
