[0019] The invention will be further described below with reference to the accompanying drawings. Example 1

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a horizontal multi-chamber fluidized bed dryer for chemical materials according to the present invention includes an industrial dryer 1, a temperature sensor 2, a humidity sensor 3, a material guide conveyor plate 5, a support frame 6, an installation frame 7, a partitioned drying device 8, a drying chamber 9, a material distribution and replenishment device 10, and a first electric push rod 23. The support frame 6 is uniformly and fixedly connected to the bottom of both sides of the drying chamber 9. The industrial dryer 1 is uniformly and fixedly installed on the top of the drying chamber 9. The temperature sensor 2 and the humidity sensor 3 are fixedly installed inside the top of the drying chamber 9. The partitioned drying device 8 is installed on the drying chamber 9. The first electric push rod 23 is installed at both ends of the partitioned drying device 8. The material distribution and replenishment device 10 is installed on the outer side of the top of the drying chamber 9. The installation frame 7 is fixedly connected to the bottom of the drying chamber 9. The material guide conveyor plate 5 is fixedly installed inside the installation frame 7. The material guide conveyor plate 5 is inclined at 30°. Connecting partition cloths 11 are fixedly installed at the middle of both ends of the drying chamber 9.

[0021] Such as 5 and Figure 6As shown, the separating drying device 8 includes a drying hole 12, a rotating drying frame 13, a drive gear 14, a fixed plate 16, a support control plate 17, a motor 18, a drive gear 19, a sliding support plate 20, and a drying chamber 22. The sliding support plates 20 are symmetrically arranged. The rotating drying frame 13 is rotatably engaged with the middle of the two sliding support plates 20. The drying chamber 22 is opened inside the rotating drying frame 13. The drive gear 14 is rotatably engaged with the middle of the outer end of the sliding support plate 20, and the middle of the drive gear 14 is fixedly connected to the middle of the end of the rotating drying frame 13. The fixed plate 16 is fixedly connected to the outer end of the sliding support plate 20. The support control plate 17 is symmetrically fixedly connected to the upper end of the fixed plate 16. The drive gear 19 is rotatably engaged with the upper end of the sliding support plate 20. The motor 18 is fixedly installed on the upper end of the fixed plate 16, and the motor... The drive end of the machine 18 is fixedly connected to the middle of the outer end of the drive gear 19. The support gear 15 is rotatably engaged with the bottom end of the sliding support plate 20. Both the drive gear 19 and the support gear 15 are meshed with the drive gear 14. The interior of the rotating drying frame 13 is uniformly fixedly equipped with partition plates 21. The drying holes 12 are uniformly opened through the rotating drying frame 13 and the partition plates 21. Starting the motor 18 can drive the drive gear 19 to rotate in both directions. The rotating drying frame 13 can be controlled to rotate in both directions by the drive gear 14. This allows the uniformly dispersed material inside the rotating drying frame 13 to tumble, ensuring that there are no dead corners in the drying process. Starting the first electric push rod 23 can raise and lower the sliding support plate 20 and the rotating drying frame 13 through the support control plate 17, thus controlling the distance between the rotating drying frame 13 and each industrial dryer 1.

[0022] The bottom end of the rotating drying frame 13 is evenly provided with discharge grooves 26. A sealing plate 24 is evenly slidably engaged inside the bottom end of the rotating drying frame 13, and the sealing plate 24 seals the discharge grooves 26. Second electric push rods 25 are distributed on both sides of the discharge grooves 26, and the second electric push rods 25 are fixedly installed inside the bottom end of the rotating drying frame 13. The front end of the second electric push rod 25 is fixedly connected to the sealing plate 24. After drying is completed, the second electric push rod 25 is activated, which allows the sealing plate 24 to slide along the bottom end of the rotating drying frame 13, so that the dried material is discharged from the discharge grooves 26 into the guide conveyor plate 5 for guiding, conveying and collection.

[0023] like Figure 7As shown, the material distribution and replenishment device 10 includes a track support plate 27, a third electric push rod 28, a feeding hopper 29, a conveying connection pipe 30, a replenishment hopper 31, a support frame 32, a sliding base 33, and a feeding frame 34. The sliding base 33 is slidably engaged with the track support plate 27. The third electric push rod 28 is fixedly connected to the outer end of the track support plate 27. The support frame 32 is fixedly connected to the sliding base 33. The replenishment hopper 31 is fixedly installed on the upper end of the support frame 32. The conveying connection pipe 30 is fixedly connected to the upper end of the replenishment hopper 31. The feeding frames 34 are evenly distributed on the track support plate 27. Inside the upright frame 32, the feeding hopper 29 is fixedly connected to the upper end of the feeding frame 34, and the feeding hopper 29 is connected to the feeding frame 34. The replenishing hopper 31 is located directly above the feeding hopper 29. The driving end of the third electric push rod 28 is fixedly connected to the outer end of the sliding base 33. Activating the third electric push rod 28 can make the sliding base 33 and the supporting upright frame 32 slide along the track support plate 27, so that the material entering the replenishing hopper 31 can be evenly added into the interior of each feeding hopper 29, and then added into the drying chamber 22 at each position through each feeding frame 34.

[0024] The feeding frame 34 is inclined and fixedly installed on the drying box 9. The bottom end of the feeding frame 34 is located above the drying chamber 22. The feeding hopper 29 is located on the outside of the drying box 9. Dispersed feeding can be achieved through each feeding hopper 29.

[0025] The track support plate 27 is fixedly connected to the drying box 9, and the sliding support plate 20 is slidably engaged at the middle of both ends of the drying box 9. The rotating drying frame 13 is located inside the drying box 9, which can quickly perform drying.

[0026] The first electric push rod 23 is fixedly installed on the drying box 9. The drive end of the first electric push rod 23 is fixedly connected to the support control plate 17. The discharge trough 26 is located directly above the material conveying plate 5, which makes it convenient to guide and collect the dried material.

[0027] The working principle of Example 1 is as follows: During use, the material is connected to the external conveying hose through the conveying connection pipe 30, and the third electric push rod 28 is activated to make the sliding base 33 and the support frame 32 slide along the track support plate 27, so that the material entering the feeding hopper 31 can be evenly added into the interior of each feeding hopper 29, and then added into the drying chamber 22 at each position through each feeding frame 34, and separated by the partition plate 21, so that the material added into the rotating drying frame 13 is evenly dispersed and isolated, which facilitates fast and thorough drying without dead corners, resulting in high drying efficiency; Furthermore, during the drying process, starting the motor 18 can drive the drive gear 19 to rotate in both directions. The drive gear 14 can control the rotation of the rotating drying frame 13 in both directions, allowing the evenly dispersed material inside the rotating drying frame 13 to tumble, ensuring thorough drying without dead corners. Activating the first electric push rod 23 can raise and lower the sliding support plate 20 and the rotating drying frame 13 via the support control plate 17, controlling the distance between the rotating drying frame 13 and each industrial dryer 1. Based on the information and data detected by the temperature sensor 2 and humidity sensor 3, automatic adjustment can be achieved, enabling fast and intelligent drying. When the sliding support plate 20 slides and rises and falls along the drying chamber 9, after drying is completed, activating the second electric push rod 25 can cause the sealing plate 24 to slide along the bottom of the rotating drying frame 13, allowing the dried material to be discharged from the discharge trough 26 into the guide conveyor plate 5 for guiding, conveying, and collection. Example 2

[0028] Based on Example 1, such as Figure 1 and Figure 8 As shown, an auxiliary drying device 4 is provided on the side of the drying box 9 away from the material distribution and feeding device 10. The auxiliary drying device 4 includes a sliding adjustment plate 35, a fourth electric push rod 36, an auxiliary drying frame plate 37, and an auxiliary industrial dryer 38. The auxiliary industrial dryer 38 is evenly fixedly installed on the auxiliary drying frame plate 37. The fourth electric push rod 36 is symmetrically distributed on both sides of the auxiliary drying frame plate 37. The sliding adjustment plate 35 is symmetrically fixedly connected to both ends of the auxiliary drying frame plate 37. The fourth electric push rod 36 is fixedly connected to the drying box 9. The sliding adjustment plate 35 and the auxiliary drying frame plate 37 are slidably engaged on the drying box 9.

[0029] In implementing this embodiment, an auxiliary drying device 4 is set on the side of the drying chamber 9 away from the material distribution and feeding device 10. The auxiliary drying device 4 can automatically operate according to the actual drying needs and the information detected by the temperature sensor 2 and humidity sensor 3. First, the fourth electric push rod 36 is automatically started, so that the sliding adjustment plate 35 and the auxiliary drying frame plate 37 slide along the drying chamber 9 into the interior of the drying chamber 9. At the same time, each auxiliary industrial dryer 38 is running. By sliding into the interior of the drying chamber 9 and approaching the rotating drying frame 13, the chemical materials inside the rotating drying frame 13 are quickly and thoroughly dried, resulting in high drying efficiency and good drying effect.
