AI Technical Summary
In the gas-solid phase reaction of existing fluidized beds, plastic particles are easily blown and accumulated, resulting in uneven contact between the particles and the wind, reducing fluidization efficiency, and unfluidized particles are mixed with the fluidized particles, making it difficult to connect to the automatic production line and reducing production efficiency.
A fluidized bed is designed, using corrugated plates to divide the inner part of the box into the upper and lower cavity, and hot air is input into the lower cavity through the blower device. The air flows from the exhaust void to the upper cavity. The plastic particles are supported by the wind and distributed evenly on the corrugated plate. The wind blows the plastic particles and moves to the discharge end to achieve continuous output.
By uniformly distributing and continuously outputting plastic particles, the fluidization efficiency and production efficiency of plastic particles are improved, ensuring uniform contact between plastic particles and wind, and suitable for the access of automated production lines.

Abstract
Description
Technical Field
[0001] The present application relates to the field of fluidized bed design, and in particular, to a fluidized bed. Background Art
[0002] If the gas-solid fluidized bed is likened to a boiling liquid layer, then the particle group in the fluidized state is equivalent to the boiling liquid itself, and the bubbles rising through the bed are equivalent to the steam bubbles in the boiling liquid.
[0003] The common fluidized bed used for plastic particles is placed flat on the ground. Since the bottom of the box carrying the plastic particles is flat, when the gas hits the plastic particles, the plastic particles are easily blown and accumulated at one end of the box, so that the contact between the internal plastic particles and the wind is uneven, reducing the fluidization efficiency of the plastic particles. Moreover, if plastic particles are continuously added to the fluidized bed, the fluidized plastic particles and the non-fluidized plastic particles are easily mixed together, making it difficult to connect to the automatic production line, reducing production efficiency. Summary of the invention

[0005] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a fluidized bed, including: a box body, one side of which forms a feed end and an air inlet end, and the opposite side forms a discharge end; a corrugated board, which is placed inside the box body, and the corrugated board divides the inner part of the box body into an upper cavity and a lower cavity, and one end of the corrugated board pointing to the air inlet end forms an exhaust gap with the inner wall of the box body, the upper cavity and the lower cavity are connected through the exhaust gap, the feed end and the discharge end are connected to the upper cavity, and the air inlet end is connected to the lower cavity; a blowing device, which is connected to the air inlet end and outputs hot air.
[0006] Furthermore, the flute direction of the corrugated board forms an angle with a line connecting the feed end and the discharge end.
[0007] Furthermore, the upper end of the corrugated board forms a first plane and a second plane that are alternately butted, the first plane is inclined toward the feeding end, the second plane is inclined toward the discharging end, and the second plane is provided with a plurality of exhaust holes.

[0012] 1. Blow air from the blowing device into the lower cavity, and the wind flows from the exhaust gap between the corrugated board and the box body into the upper cavity. The plastic particles entering the box body from the feeding end are lifted by the wind and fall on the corrugated board.

[0027] Reference Figure 1-3 ,
[0028] A fluidized bed comprises: a box body 1, a corrugated board 2 and an air blowing device. A feed end 11 and an air inlet end 12 are formed on one side of the box body 1, and the height of the feed end 11 is higher than that of the air inlet end 12, and a discharge end 13 is formed on the opposite side of the box body 1. The corrugated board 2 is placed horizontally inside the box body 1, and the corrugated board 2 divides the inside of the box body 1 into an upper cavity 14 and a lower cavity 15. One end of the corrugated board 2 pointing to the air inlet end 12 forms an exhaust gap 16 with the inner wall of the box body 1, and the upper cavity 14 and the lower cavity 15 are connected through the exhaust gap 16. The feed end 11 and the discharge end 13 are connected to the upper cavity 14, and the air inlet end 12 is connected to the lower cavity 15. The blowing device is connected to the air inlet end 12, and is used to input hot air into the lower cavity 15. After the hot air fills the lower cavity 15, it enters the upper cavity 14 from the exhaust gap 16. Since the hot air forms a high air pressure from bottom to top at the exhaust gap 16, the plastic particles are lifted up by the hot air and fall on the upper end of the corrugated board 2 with the flow of the hot air. The hot air blows the plastic particles and distributes the plastic particles in the array grooves of the corrugated board 2, thereby dividing the plastic particles into arrays to fully contact with the hot air. Among them, it is common knowledge in the field of materials that the corrugated board 2 has continuous array grooves. When the airflow of the lower layer of the hot air moves in contact with the upper end of the corrugated board 2, it will lift the plastic particles group by group and move them to the discharge end 13 until the plastic particles are discharged from the discharge end 13.
[0029] Specifically, the flute direction of the corrugated board 2 forms an angle of 90 degrees with the line connecting the feeding end 11 and the discharging end 13. The edge direction of the corrugated board 2 is a common concept in the art. The corrugated board 2 forms a certain obstacle to the movement of the plastic particles, preventing the plastic particles from being directly discharged from the discharging end 13 along with the hot air, resulting in insufficient processing time of the plastic particles in the box 1.
[0030] Specifically, the upper end of the corrugated board 2 forms a first plane 21 and a second plane 22 that are alternately connected. The first plane 21 is inclined toward the feeding end 11 at an angle of 30 degrees relative to the ground, and the second plane 22 is inclined toward the discharge end 13 at an angle of 60 degrees relative to the ground. The second plane 22 is provided with a plurality of exhaust holes 221. A part of the hot air in the lower cavity 15 is blown into the upper cavity 14 through the exhaust holes 221. Since the second plane 22 is inclined toward the discharge end 13, the hot air from the exhaust holes 221 will push the plastic particles, providing auxiliary thrust for the plastic particles to move toward the discharge end 13.
[0031] Specifically, one side of the corrugated board 2 in the corrugated direction is in contact with the inner wall of the box body 1, and the opposite side is separated from the inner wall of the box body 1. A part of the hot air in the lower cavity 15 flows upward from the separation point between the corrugated board 2 and the inner wall of the box body 1. When multiple groups of plastic particles move in a straight line from the feed end 11 to the discharge end 13, this part of the hot air provides an upward thrust to the multiple groups of plastic particles from one side inside the box body 1, so that the multiple groups of plastic particles are turned over when moving in a straight line, thereby improving the contact efficiency between the plastic particles and the hot air.
[0032] Specifically, the air blowing device includes: a blower 3 and a heating coil 4. The heating coil 4 is placed at the input end of the blower 3 to heat the external air entering the blower 3, and the output end of the blower 3 is connected to the air inlet end 12 of the box body 1 to blow hot air into the lower cavity 15 of the box body 1.
[0033] Specifically, the upper end of the box body 1 also forms an exhaust port 17 for exhausting waste gas generated by the reaction of hot air and plastic particles.
[0034] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) and the technical solutions formed.
