Description

Novel grid plate type material cooling machine

Technical Field

The utility model relates to the technical field of grain and oil processing, in particular to a novel grid plate type material cooler, which is used for the field of cooling pre-pressed peanut biscuits made of peanut raw materials in the grain and oil industry.

Background

The cooler is the core equipment for cooling biscuits in the grease processing technology, and whether the transmission operation is stable, the energy consumption index is reasonable, and whether the fire safety and environmental protection reach the standard directly relates to the economic benefit and social benefit of grease processing enterprises. Therefore, the selection of a proper, energy-saving and safe cooling machine has a far-reaching significance for grease processing enterprises.

Well known oil cooling devices are flap coolers, vibrating fluidized beds, air cooled conveyors, and the like.

The hot material of plate cooler theory of operation gets into the feed bin through the air seal machinery after, piles up gradually, after reaching certain height, drives the certain angle of turning over the rotation of board through automatic control component with a certain quantity of connecting rods, makes the material on the board that turns over fall, unloads. When the discharging is larger than the feeding, the discharging is not carried out. During normal work, the feeding and the discharging of the cooler are basically equal, namely, the material is basically kept at a certain height so as to ensure that the material has enough cooling time to be adjusted by adjusting the turnover angle of the turning plate. In the whole process, the cooling fan is always in an open state. The materials gradually descend slowly along with the reciprocating motion of the turning plate, the cooling air is changed into heat from cold from bottom to top, and in the working process, because the hot materials at the upper part meet hot air and the cold materials at the lower part meet cold air, the materials are uniformly and fully cooled in the descending process and become hard and solid, and the temperature of the materials is further reduced; the cooling machine has the defects of uneven material distribution, short material cooling time, limited yield and the like.

The working principle of the vibrating fluidized bed is that materials enter the machine from a feeding hole, the materials are thrown and continuously move forwards along the horizontal direction under the action of a vibrating force, cold air upwards passes through the fluidized bed to exchange heat with hot materials, hot air is discharged from an air outlet after being dedusted by a cyclone separator, and dry materials are discharged from a material outlet. However, the material deviation problem often occurs in the operation of the vibrated fluidized bed, which is caused by the deviation of the vibration included angle between the two motors when the vibrating motor is installed, and the material discharging speed is too fast or too slow, thereby affecting the cooling effect of the material.

The material falls on the horizontal sieve plate of the conveyer uniformly through a material distributing device, cold air blown by a fan passes through the sieve plate and a material layer while moving forwards, the material in the material layer is cooled, the cooled material blank is discharged out of the machine at a gap at the tail end of the sieve plate, and hot air is discharged from an air outlet at the upper part of the shell. When the device is used, however, care needs to be taken to avoid the local retention of the blanks in the device, otherwise the blanks are easily burnt and spontaneously combusted; meanwhile, the material feeding in the previous process is mainly monitored, and the material is carried with sparks due to overhigh temperature, so that dead-angle material blanks in the equipment can be spontaneously combusted. In addition, the material with higher powder degree is not recycled and directly enters the next procedure, and then the corresponding index parameters are influenced.
