(54) VIBRATOR DRYER FOR BULK MATERIALS

i

The invention relates to the drying of bulk materials, such as wood chips, match straw, granulated material, and so on.

The closest to the technical essence and the achievement of the MOI result is a vibrating dryer, comprising a housing with supply and discharge connections for the heat transfer fluid, trays arranged in the housing, combined into blocks equipped with a vibrating alarm P.

However, the dryer has insufficient heat and mass transfer intensity.

The aim of the invention is to increase the intensity of heat and mass transfer.

This goal is achieved by the fact that the trays of one unit are placed between the trays of another unit, and horizontal screens are installed between the walls of the chassis and the trays placed from the Russ to the Rus in alternate order to provide a zigzag movement of the coolant, and the working surface of the trays is made in the form of a stepped grid .

FIG. 1 schematically shows a dryer, a general view, on. FIG. 2 shows section A-A in FIG. one .

The dryer includes a housing 1, in the upper part of which are placed the load shutter 2, the fan 3 and the heater 4. On the side walls there are crank mechanisms 5 and the shutter 6 for unloading the dry material.

Claims (1)

9. Trays 8 are connected to crank mechanisms 5 with gms 10. Perpendicular to the longitudinal walls inside 1 in the plane of working sites 9, screens 11 39 are fixed so that they form a zigzag-shaped channel for the drying agent. The dryer works as follows. Bulk material is evenly fed through loading gate 2 to trays 8, crank mechanisms 5 are activated, which, by means of traces 10, cause trays 8 to swing, so that the deviation from vertical position of the suspensions by rolling produces one way This granular material is transferred from one tray to the other in a uniform layer and uniform speed along the entire length of the transport and, pouring it over the stepped grids 9, using the shutter 6, the dried material is removed from the dryer. The drying agent, for example, the air, is blown by the fan 3 through the heater 4 (heated to the required temperature) under the trays 8 and moves upward along the zigzag channel formed by the screens 12, washing the bulk material from below. / Memory up and partially penetrating it in the process of movement. Claims of the invention Vibration dryer for bulk materials, comprising a housing with coolant inlet and outlet nozzles, trays arranged in a housing, combined in blocks equipped with a vibration drive, characterized in that, in order to intensify heat and mass transfer, the trays of one unit are placed between the trays of another unit , and between the walls of the case and the trays are installed horizontal screens placed from the Rus to the Rus in alternate order to provide a zigzag movement of the coolant, and the working Trays surface formed in a stepped grid.
