Description

The invention relates to the field of production, namely, to coolers of pressed extruded materials, mainly granules.

The purpose of the invention is to reduce energy consumption and simplify the design of the cooler,.

In the pellet cooler, which provides material unloading through vibration, it is advisable to save energy by creating the dynamic energy of a jet of air supplied to cool the material by vibrating to create energy. Rattor, in the form of an eccentric shaft with a reinforced krypchatka at one end and an elastic plate pivotally connected to its other end, while the ratchet is mounted in the. the fan pipe and the plate is connected to the bottom of the trays.

FIG. Figure 1 shows schematically the proposed cooler of granules with elastic elements in the form of stretch spring; in fig. 2.- mounting unit of the lower part of the box with elastic elements in the form of compression springs; in fig. 3 is a section A-A in FIG. one.

The pellet cooler includes a vertical case 1 with louvers of the side walls for the passage of cooling air, a pipeline 3 of the fan 4, a loading window 5 and a discharge device including those located under the case of the Pharynx 6 in the form of detachable arms, the lower part 7 of which is mounted on displaced in the vertical plane of the elastic elements, made in the form of compression springs 8 or tension springs 9, and the upper part 10 is rigidly connected to the housing 1, a vibrator made in the form of an eccentric shaft 11c. and one end 12 of the impeller 13 located in the pipe 3 ,. and hinged to the other end 14 of the shaft 11 by an elastic plate 15 connected to the bottom part 7 of the trays 6.

During operation of the cooler, the body 1 is loaded with granules through the window 5. The granules are blown through the louver 2 by atmospheric air and, after cooling, are discharged.

The blown air by the fan 4 through the granules in the housing 1 passes through the pipeline 3, acts on the impeller 13, causes the rotation

eccentric shaft Some end 14 through an elastic plate 15 pivotally connected to the end 14 of the shaft 11 and the lower part 7 of the trays causes it to vibrate, due to which the granules are unloaded from the housing 1.

At the beginning of the loading of the housing 1 with granules, the lower part 7 is raised with elastic elements 8 or 9 and is in the upper position, the window size between the lower 7 and the upper 10 parts of the trays is minimal, the load is insignificant.

The higher the level racked in the housing 15 1, the greater the pressure on the lower

the part 7 of the trays 6, the more the spring 9 is stretched or the springs 8 are compressed, increasing the cross-section of the trays 6, the more. 20 zero-unit per time is increased. Reducing the granules in the body reduces the speed of their unloading.

In the operation mode of the cooler, the level of the granules should vary only 25 within the upper non-allied part of the hull, 1.,

When the work is completed and the granules are completely unloaded from the body 1, the level of the granules falls, the louvers 2 open, the air velocity in the pipeline increases, the shaft speed of 1.1 years old-J is, the frequency of the lower part 7 rises ,. unloading speed increases, which reduces the time to stop cooling and all equipment.

 Due to the presence of an elastic plate 15 between the eccentric shaft 11 and the lower part 7 of the chute 6, its vibration with the case of 1 loaded granules begins at small amplitudes with an increase to a maximum equal to the eccentricity value, since the friction of rest between the granules e5 more friction of movement. A smooth entry into the vibration of the lower part 7 reduces the destruction of the granules, since the lateral displacement of the granules with each other during ionization into the trays 6 with a full am-JQ bulk begins already at the moment of their movement.

Thus, when using an eccentric shaft with an impeller at the end, 55 located in the fan piping as a vibrator, there is no need for a separate vibrator with an individual drive and control of it, which ultimately reduces power consumption and simplifies Cooling design in general.

A smooth entry into the nominal mode of operation of the vibrator improves the quality of cooling of the granules due to a decrease in their destruction during unloading, and an increase in the speed of discharge due to an increase in the revolutions of the eccentric shaft with a full unloading of the body reduces operating costs.
