Description
Technical Field
The invention relates to the field of dryer equipment, in particular to feeding equipment and a dryer.
Background
Referring to fig. 1 and 2, the current dryer is a rotary cylindrical device, the cylinder is composed of an outer cylinder 10 and an inner member (not shown in the drawings), and the inner member is a drying pipe. The cylinder (cylinder for short) is installed and forms a certain included angle with the horizontal plane, and the drying pipe rotates along with the cylinder during operation. The material passes from the wet material bin, through chute 20, and through the distributor 30 of the dryer, uniformly distributing raw material of a certain particle size into a plurality of drying tubes inside the rotating drum. The guide vane is installed in the drying pipe, the material moves in the drying pipe through gravity and the guide effect of the vane, and along with the continuous rotation of the cylinder, the dried material continuously flows out from the other end of the cylinder. The heat energy required by drying is provided by low-pressure steam in a multi-pipe system, the low-pressure steam enters from one end 40 of the main shaft of the cylinder body and rapidly diffuses outwards from the main shaft to the outer surface of the drying pipe, and raw materials in the drying pipe are heated through indirect heat exchange, so that the moisture in the materials is heated and evaporated, and the purpose of reducing the moisture is achieved. Air entering the drying pipe together with the material brings moisture out of the drying pipe, enters a dust removal system and is separated from the dry powder material in the dust removal system.
The traditional chute feed arrangement of desiccator, the material is from being wet material storehouse, through chute 20 to distributing device 30, evenly distributes the material to the inside numerous drying tubes of rotatory barrel by distributing device 30, runs into following problem in the equipment use: firstly, the crushed materials in the wet storage bin are easier to agglomerate (the caking phenomenon of the materials with high water content is more serious). The agglomerated raw materials directly enter the drying pipes of the internal parts of the dryer through the chute 20 and the distributor 30, so that the blocking of the pipes of the dryer occurs, the equipment is stopped, the production is affected, and the maintenance cost is increased. Secondly, since the drying pipes on the end plate 50 of the dryer are circumferentially arranged, the amount of material required from the inner side to the outer side of the end plate 50 is reduced to a large amount during the operation of the device, and the amount of material required varies according to the rotation speed of the device. The chute feeding device is characterized in that a switching valve is arranged above a feeding chute to adjust the feeding amount, and the feeding amount can be controlled in such a way as to meet the change of the materials required by the dryer, but the feeding amount of the drying pipes at the inner side and the outer side of the end plate 50 cannot be adjusted, so that the feeding uniformity of the drying pipes cannot be ensured, and the drying performance of the dryer is affected. Thirdly, during the operation of the dryer, some sundries are mixed in the storage bin and directly enter the dryer through the feeding chute 20, so that equipment is in fault, and production is affected.
