Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a feeding device for a food-grade fixed fluidized bed. Background Technology

[0002] Currently, existing food-grade fixed fluidized bed feeders use strip-shaped rotary valves for centralized feeding, which can easily lead to accumulation and blockage of the air distribution plate at the feed end, causing production accidents such as bed collapse and shutdown. Utility Model Content

[0003] The purpose of this utility model is to provide a feeding device for a food-grade fixed fluidized bed, so as to solve the problems mentioned in the background art, such as the easy accumulation of existing food-grade fixed fluidized bed feeding devices at the feeding end, blockage of the air distribution plate, bed collapse, shutdown and other production accidents.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a food-grade fixed fluidized bed, comprising a feeding device body, a feeding channel at the top of the feeding device body, a discharging channel at the bottom of the feeding device body, an impeller feeding valve inside the feeding device body, the impeller feeding valve comprising a feeding rotor and an impeller disposed on the feeding rotor, and a driving device disposed on the outside of the feeding rotor.

[0005] The drive unit includes a drive shaft and a motor. One end of the drive shaft is fixedly connected to the fabric rotor, and the other end of the drive shaft is fixedly connected to the output end of the motor.

[0006] A material distribution plate is installed at the discharge channel.

[0007] The drive unit is located on one side of the main body of the material distributor, and a maintenance flange is provided on the side wall of the other side of the main body of the material distributor.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This invention adds a high-speed rotating impeller distribution valve to the feed end of the existing fixed fluidized bed drying system. The impeller of the distribution valve rotates at high speed to generate downward airflow, which mixes with the material and enters the fixed fluidized bed. This prevents material from accumulating and clogging the air distribution plate, optimizes the production process, and improves operating efficiency. Attached Figure Description

[0011] Figure 2 This is a schematic diagram of the impeller feed valve structure in this utility model.

[0012] In the above attached figures, the main body of the material distributor is 1, the motor is 2, the coupling is 3, the drive shaft is 4, the bearing is 5, the packing seal is 6, the feed channel is 7, the material distributor rotor is 8, the impeller is 9, the maintenance flange is 10, and the discharge channel is 11. Detailed Implementation

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] like Figure 1-2 As shown, this utility model provides a feeding device for a food-grade fixed fluidized bed, including a feeding device body 1. The top of the feeding device body 1 is provided with a feeding channel 7, and the bottom of the feeding device body 1 is provided with a discharging channel 11. The material enters from the feeding channel 7 and is discharged from the discharging channel 11 into the fluidized bed. An impeller feeding valve is provided inside the feeding device body 1. The impeller feeding valve includes a feeding rotor 8 and an impeller 9 disposed on the feeding rotor 8. The feeding rotor 8 drives the impeller 9 to rotate, so that the impeller feeding valve rotates as a whole inside the feeding device body 1. The high-speed rotation of the impeller 9 generates downward airflow, which mixes with the material and enters the fixed fluidized bed, preventing concentrated blockage and blockage of the air distribution plate, optimizing the production process and improving operating efficiency. A driving device is provided on the outside of the feeding rotor 8, which drives the feeding rotor 8 to rotate.

[0015] The drive unit includes a drive shaft 4 and a motor 2. One end of the drive shaft 4 is fixedly connected to the fabric rotor 8, and the other end of the drive shaft 4 is fixedly connected to the output end of the motor 2. The drive shaft 4 and the output end of the motor 2 are fixedly connected by a coupling 3. A bearing 5 is provided in the middle of the drive shaft 4. The drive shaft 4 is rotatably mounted to the mounting base through the bearing 5. When the motor 2 is started, the motor 2 drives the fabric rotor 8 to rotate through the drive shaft 4. The drive shaft 4 makes the rotation of the fabric rotor 8 more stable and faster.

[0016] The rotating shaft passes through the main body 1 of the material distributor and enters the main body 1 to be fixedly connected to the material distributor rotor 8. A packing seal 6 is provided at the contact point between the rotating shaft and the side wall of the main body 1 of the material distributor. The packing seal 6 can prevent the material inside the main body 1 of the material distributor from overflowing.

[0017] A material distribution plate is installed at the discharge channel 11. The material distribution plate can disperse the material passing through the discharge channel 11 and prevent the material in clumps from entering the fluidized bed. The discharge channel 11 is set as a cone or trapezoidal cylinder with the lower port larger than the upper port, which is conducive to the dispersion of the material passing through the impeller material distribution valve under the action of wind.

[0018] The drive unit is located on one side of the main body 1 of the material distributor. A maintenance flange 10 is provided on the side wall of the other side of the main body 1 of the material distributor. The impeller material distribution valve inside the main body 1 of the material distributor can be inspected by opening the maintenance flange 10.

[0019] This invention adds a high-speed rotating impeller distribution valve to the feed end of the existing fixed fluidized bed drying system. The impeller 9 of the impeller distribution valve rotates at high speed to generate downward airflow, which mixes with the material and enters the fixed fluidized bed. This prevents material from accumulating and clogging the air distribution plate, optimizes the production process, and improves operating efficiency.
