[0002] Vibrating fluidized bed dryer, or simply vibrating fluidized bed dryer, is a new type of high-efficiency fluidized bed drying equipment suitable for drying granular and powdery materials. Vibrating fluidized bed is a new type of equipment that has been gradually developed and expanded in application over the past decade, and is increasingly becoming a major type of drying equipment. Vibrating fluidized bed is a new type of drying device that applies a vibration source with specific requirements to a regular fluidized bed dryer. Vibrating fluidized bed dryers are usually required for soil thermal desorption.

[0003] A prior art vibrating fluidized bed dryer, with application number 202421130971.3, includes a vibrating fluidized bed body. A feed inlet is arranged on one side of the top of the vibrating fluidized bed body, and a discharge outlet is arranged on one side of the bottom of the vibrating fluidized bed body. A perforated plate is arranged inside the drying chamber of the vibrating fluidized bed body, and a thickness-limiting structure is arranged inside the drying chamber at the feed inlet. This invention has the advantage of adjusting the material thickness inside the drying chamber of the vibrating fluidized bed body; however, it is inconvenient to discharge the dried material from the machine body, and residue is easily left in the discharge. Utility Model Content

[0004] The purpose of this invention is to provide a double-layer vibrating fluidized bed dryer to solve the problems in the prior art where it is inconvenient to discharge the dried material from the machine body and where material residue is easily left behind during discharge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-layer vibrating fluidized bed dryer, including a base plate, a dryer body is provided on the upper side of the base plate via a vibrating spring and a support plate, a feed inlet and a discharge outlet are respectively provided at both ends of the dryer body, a chain is connected to the middle of the dryer body via a drive shaft and a sprocket, multiple fluidized bed plates are rotatably arranged between the two chains, and the multiple fluidized bed plates are hinged to each other, and a scraper is provided on the upper side of the discharge outlet via a transverse support and a cylinder.

[0006] Furthermore, one end of the drive shaft is connected to an electric motor via a gear set, and the electric motor is fixedly mounted on the outer wall of the dryer body.

[0007] Furthermore, the fluidized bed plate is provided with connecting blocks and connecting grooves on both sides, and the connecting blocks between two adjacent fluidized bed plates are hinged in the connecting groove on one side by a pin.

[0008] Furthermore, the top of the connecting groove is provided with an exhaust port, and the side wall of the exhaust port is provided with multiple hot air inlets and a vibration motor.

[0009] Furthermore, one end of the scraper is provided with a flexible scraping layer, and one end of the scraper is inclined toward the discharge port.

[0010] Furthermore, the scraper is provided with limiting sliders on both sides, and the limiting sliders are elastically slidably disposed in the limiting groove at one end of the transverse support by means of springs.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses multiple fluidized bed plates, with both ends of the fluidized bed plates rotatably connected to a chain. Adjacent fluidized bed plates are also hinged together. When the chain is driven to rotate by a motor, multiple fluidized bed plates can be moved horizontally for adjustment. This facilitates the conveying of dried material to the discharge port, making discharge convenient, quick, and thorough.

[0013] Furthermore, the present invention has a scraper plate on the upper side of the discharge port via a transverse support and a cylinder, and one end of the scraper plate is inclined toward the discharge port, so as to scrape the outer wall of the fluidized bed plate and prevent the material from sticking to the outside of the fluidized bed plate and affecting the thoroughness of the discharge.

[0014] This invention features a limiting slider on both sides of the scraper, which is elastically slidably mounted in a limiting groove at one end of the transverse support via a spring. This allows the scraper to be elastically mounted at one end of the transverse support, facilitating elastic scraping of the outer wall of the fluidized bed plate, preventing damage to the fluidized bed plate from hard scraping, and improving scraping efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 In this embodiment of the present invention, a double-layer vibrating fluidized bed dryer includes a base plate 5. A dryer body 1 is mounted on the upper side of the base plate 5 via a vibrating spring 4 and a support plate 11. The dryer body 1 has an inlet 2 and an outlet 3 at both ends. An exhaust port 6 is located at the top of the connecting groove 23. Multiple hot air inlets 7 and a vibrating motor 8 are located on the sidewall of the exhaust port 6. A chain 12 is driven through a drive shaft 14 and a sprocket 13 in the middle of the dryer body 1. Multiple fluidized bed plates 17 are rotatably mounted between two chains 12, and the multiple fluidized bed plates 17 are hinged together. The fluidized bed plate 17 is provided with connecting blocks 22 and connecting grooves 23 on both sides. The connecting blocks 22 between two adjacent fluidized bed plates 17 are hinged in the connecting grooves 23 on one side by pins 24. One end of the drive shaft 14 is connected to the motor 16 through the gear set 15. The motor 16 is fixedly installed on the outer wall of the dryer body 1. When the chain 12 is driven to rotate by the motor 16, it can drive multiple fluidized bed plates 17 to move and adjust horizontally, so as to facilitate the conveying of the dried material to the discharge port 3 for discharge. The discharge is convenient, fast and thorough.

[0024] like Figure 2 and Figure 4 As shown, in order to improve the thoroughness of material discharge, a scraper 18 is provided on the upper side of the discharge port 3 via a transverse support 9 and a cylinder 10. One end of the scraper 18 is inclined toward the discharge port 3, so that the outer wall of the fluidized bed plate 17 can be scraped to prevent the material from sticking to the outside of the fluidized bed plate 17 and affecting the thoroughness of material discharge.

[0025] like Figure 3 and Figure 4 As shown, in order to perform elastic scraping on the outer wall of the fluidized bed plate 17, a flexible scraping layer is provided at one end of the scraper plate 18. Limiting sliders 20 are provided on both sides of the scraper plate 18, and the limiting sliders 20 are elastically slidably disposed in the limiting groove 19 at one end of the transverse support 9 by means of spring 21. This allows the scraper plate 18 to be elastically slidably installed at one end of the transverse support 9, which facilitates elastic scraping on the outer wall of the fluidized bed plate 17, prevents hard scraping from damaging the fluidized bed plate 17, and also improves the efficiency of scraping.

[0026] The working principle and usage process of this utility model are as follows: In use, the fluidized bed plate is set as multiple fluidized bed plates 17, and the two ends of the fluidized bed plates 17 are rotatably connected to the chain 12. At the same time, the adjacent fluidized bed plates 17 are hinged. The material is put into the material end of the fluidized bed plate 17 of the dryer body 1 through the feed port 2. The fluidized bed plate 17 is driven to move and convey the material through the chain 12 and sprocket 13. At the same time, hot air is used to dry the material. After drying, the dried material is easily conveyed to the discharge port 3 for discharge. The discharge is convenient, fast and thorough.
