Description

TECHNICAL FIELD

[0001] The utility model relates to fluidized bed technical field more specifically, the utility model relates to a kind of fluidized bed with uniform material distribution function. BACKGROUND

[0002] Fluidized bed is widely used in many industrial production processes, such as chemical industry, pharmaceutical, energy and other fields, and it is a device that uses gas or liquid to make solid particles in a fluidized state to carry out various processes.

[0003] According to the prior art, the fluidized bed blows out the dried lithium chloride from the discharge port, transports it to the vibrating screen, and packages the lithium chloride particles required after screening by the vibrating screen. During the operation of the vibrating screen, the lithium chloride is exposed to the air. Since the lithium chloride is hygroscopic, it is easy to stick to the vibrating screen plate, affecting the working efficiency of the vibrating screen and the quality of the lithium chloride. Moreover, the existing fluidized bed discharges the material by wind force to make it suspended in the fluidized bed, and then blows it out from the discharge port without other auxiliary devices to speed up the discharge rate. The fluidized bed with the structure of screening the material from the discharge port and improving the discharge rate is simple in structure, convenient to implement, and can screen the material in the fluidized bed, reduce the use of other screening equipment, and make the material not exposed to the air during screening. The guide plate also improves the screening and discharge rate.

[0004] Fluidized bed often causes local accumulation of material in the bed due to uneven distribution of material, which not only causes excessive reaction of the accumulated material and produces a large amount of impurities, affecting the purity of the product, but also causes waste of raw materials in other areas due to insufficient reaction, greatly reducing the reaction efficiency. Therefore, a fluidized bed with uniform material distribution function is proposed. SUMMARY

[0005] In order to overcome the problems and defects in the prior art, the utility model provides a fluidized bed with uniform material distribution function to solve the problems in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a fluidized bed with uniform material distribution function, comprising a fluidized bed body, a support rod fixedly connected to the inner wall bottom of the fluidized bed body, a gas flow distribution plate fixedly installed at the top of the support rod, a gas hole formed in the top surface of the gas flow distribution plate, and a material distribution mechanism arranged between the fluidized bed body and the gas flow distribution plate.

[0007] The cloth mechanism comprises a pretreatment box, the pretreatment box is installed inside the fluidized bed body, a sealing cover is fixedly installed at the top of the pretreatment box, a feeding pipe is fixedly connected to the top of the sealing cover, a first motor is installed at the top of the sealing cover and close to one side of the feeding pipe, a rotating shaft is fixedly connected to the bottom of the first motor, a scattering rod is fixedly connected to the two sides of the rotating shaft, a communication pipe is fixedly communicated to the bottom of the pretreatment box, a rotating pipe is installed at the bottom of the communication pipe, an elastic hose is connected to the end of the rotating pipe, a cloth pipe is fixedly connected to one end of the elastic hose, and a rotating mechanism is arranged between the cloth pipe and the communication pipe.

[0008] Preferably, the rotating mechanism comprises a fixed box, the fixed box is fixed outside the communication pipe, a second motor is fixedly installed at the top of the fixed box, and a rotating shaft is fixedly connected to the output end of the second motor.

[0009] Preferably, the rotating shaft is fixedly connected with a first gear at the bottom, the first gear is engaged with a second gear at one side, and the second gear is fixedly sleeved outside the rotating pipe.

[0010] Preferably, the rotating pipe and the communication pipe are rotatably connected with the fixed box, and a rotating joint is fixedly installed between the communication pipe and the rotating pipe.

[0011] Preferably, the rotating pipe is hingedly connected with an elastic cylinder at the front side, and the elastic cylinder is hingedly connected between the bottom and the cloth pipe.

[0012] Preferably, the rotating shaft is rotatably connected between the rotating shaft and the sealing cover, the rotating shaft penetrates through the sealing cover and extends into the pretreatment box.

[0013] Preferably, the feeding pipe penetrates through the fluidized bed body and extends to the top of the fluidized bed body.

[0014] The technical effects and advantages of the present application are as follows:

[0015] 1. By setting the cloth mechanism and the rotating mechanism, the first motor drives the rotating shaft and the scattering rod to scatter and pretreat the material, effectively avoiding material caking, ensuring that the material is in a relatively uniform state when entering the subsequent cloth link, and at the same time, the second motor drives the rotating pipe to rotate and the elastic cylinder to adjust the angle of the cloth pipe, so that the material can be uniformly distributed in the horizontal and vertical directions, and finally uniformly distributed on the airflow distribution plate through centrifugal force and gravity, greatly improving the uniformity of the material distribution in the fluidized bed body, and the uniformly distributed material enables each part of the material to fully contact the reaction substance and energy during the chemical reaction process, avoiding the situation that part of the material is not fully reacted or over-reacted due to material accumulation or uneven distribution, thereby significantly improving the reaction efficiency, reducing the reaction time and the waste of raw materials, and reducing the production cost.

[0016] 2. The first motor drives the rotating shaft to rotate, causing the dispersing rods on the outside of the shaft to break up the material, preventing clumping and ensuring uniformity of the fabric. This uniform material distribution increases the contact area between the material and the fluidizing gas, resulting in more even and rapid heat transfer between them. Mass exchange is also more efficient. The improved reaction efficiency and enhanced heat and mass transfer effects due to the uniform material distribution ensure the quality of the final product, making its performance indicators more stable and consistent. Simultaneously, the efficient fabric distribution and reaction process shortens the production cycle and improves overall production efficiency. Attached Figure Description
