Description

Fluidized bed for preventing particle shrinkage

Technical Field

The utility model belongs to the technical field of the fluidized bed, concretely relates to fluidized bed for preventing granule shrink.

Background

The foam particles can not be contacted with air immediately after being expanded, if the foam particles are contacted with air immediately, the particles after being expanded shrink, the fluidized bed in the prior art adopts direct contact with air, the particle shrinkage can not be avoided, and aiming at the defects, a fluidized bed for preventing the particle shrinkage, which has a reasonable structure, prevents the particle shrinkage and is convenient to operate, needs to be developed; therefore, it is very important to develop a fluidized bed for preventing particle shrinkage, which has a reasonable structure, prevents particle shrinkage, and is convenient to operate.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the defects of the prior art and providing a fluidized bed for preventing particle shrinkage, which has reasonable structure, prevents particle shrinkage and is convenient to operate.

The purpose of the utility model is realized like this: the fluidized bed comprises a fluidized bed body, wherein a feeding pipe for conveying expanded particles into the fluidized bed body is arranged on the fluidized bed body, a ventilation window with grids is arranged on the side face of the fluidized bed body, a bed body cover is arranged at the upper end of the fluidized bed body, the fluidized bed body is connected with a feeding box, the feeding box is provided with a discharge port for discharging materials from the fluidized bed body, a baffle is arranged at the discharge port, and feeding holes are uniformly formed in the lower end face of the feeding box.

The fluidized bed body is cuboid in structural shape.

The bed body is covered with a net cover, and the net cover is composed of grids with ventilation holes.

The feeding box is connected with the fluidized bed body through bolts.

The ventilation window and the net cover are made of ventilation net cloth, and the diameter of the net holes is smaller than that of the particles.

The structural shape of the feeding box is a cuboid structure.

The utility model has the advantages that: the utility model has the advantages that the direct contact air of the particles after the puffing is prevented, the condition of particle shrinkage is avoided, the particles after the puffing are sent into the fluidized bed body with the cuboid structure for pretreatment, the bed body cover with the net cover and the ventilation window are arranged on the fluidized bed body, and the slow contact air of the particles after the puffing is used, so the purpose that the particles are not shrunk can be achieved, if the particles after the puffing are directly contacted with a large amount of air, the precooling is inevitably and generally shrunk, and the purpose of the puffing can not be achieved; therefore, the utility model has the advantages of rational in infrastructure, prevention granule shrink and convenient operation.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Example 1

As shown in fig. 1-4, a fluidized bed for preventing particle shrinkage includes a fluidized bed body 1, a feeding pipe 3 for feeding expanded particles into the fluidized bed body 1 is disposed on the fluidized bed body 1, a ventilation window 2 with a grid is disposed on a side surface of the fluidized bed body 1, a bed body cover 4 is disposed at an upper end of the fluidized bed body 1, the fluidized bed body 1 is connected with a feeding box 5, the feeding box 5 is disposed at a discharge port 7 for discharging from the fluidized bed body 1, a baffle 8 is disposed at the discharge port 7, and feeding holes 9 are uniformly disposed on a lower end surface of the feeding box 5.

The embodiment has the advantages that the expanded particles are prevented from directly contacting with air, the condition of particle shrinkage is avoided, the expanded particles are sent into the fluidized bed body with the cuboid structure for pretreatment, the bed body cover with the net cover and the ventilation window are arranged on the fluidized bed body, and the function is to slowly contact with the air, so that the purpose of particle non-shrinkage is achieved, if the expanded particles directly contact with a large amount of air, precooling is inevitable and general shrinkage is achieved, and the purpose of expansion is not achieved; therefore, the utility model has the advantages of rational in infrastructure, prevention granule shrink and convenient operation.

Example 2

The fluidized bed body 1 is cuboid in structural shape.

This embodiment designs the structure of fluidized bed body 1 into a cuboid, is convenient for carry the foam particle and slowly contact the air, avoids the granule shrink.

Example 3

The bed body cover 4 is provided with a net cover 6, and the net cover 6 is composed of grids with ventilation holes.

In this embodiment, the bed cover is provided with a plurality of net covers, and the net covers are composed of grids with ventilation holes, which is beneficial to the slow contact of the particles with air.

Example 4

The feeding box 5 is connected with the fluidized bed body 1 through bolts, the ventilation window 2 and the net cover 6 are ventilation net cloth, the diameter of the net hole is smaller than that of particles, and the feeding box 5 is of a cuboid structure.

The bolt connection in the embodiment has the advantages of convenient disassembly and maintenance and stable structure; the ventilation window and the net cover are made of ventilation net cloth, and the ventilation net cover has the advantages of ventilation and convenience in pretreatment.

The present invention is further described in the detailed description, rather than in the limited form thereof, and it will be obvious to those skilled in the art that changes may be made in the structure without departing from the spirit and scope of the invention, and it is intended that all such changes be covered by the appended claims.
