Description

A known device for drying loose materials, a corymer of vinyl chloride resins, has an outer cylindrical heat-insulating casing in which a vertical vibratory conveyor is enclosed, made in the form of a pipe with a screw-like working tool mounted on it. The diameter of the turns of the working organ increases as the angle increases and the angle of elevation decreases. The tool is used at the same time to dry the material and transport it from the bottom upwards from the loading hopper to the unloading material in the coolant flow.

The proposed device does not have an outer casing, and the screw surface of the conveyor is provided with gaps, which are open but with different forming pipes for partial transfer of material from one turn to another. In addition, the electric heating elements are located on the inner surface of the conveyor pipe or directly on the lower surface of the working body, but with which the material being dried moves. Such an embodiment of the device simplifies and cheapens the co-structuring of the dryer and improves the contact of all the particles of the material with the heating surface of the working body while ensuring the dynamic balance of the conveyor.

The drawing shows the proposed device.

The accepted conditional are designated: / -the working organ (pan) - 2- heating elements; ; - vertical vibrating conveyor; - coupling; 5-elastic vibration conveyor system; - vibrators; 7 electric motor; 5-bunker; 9-feeder; / (- electromagnetic feeder vibrator; // - tray for loading the material being dried; / 2 - chute for unloading the dried material.

Verticals | The vibrating conveyor, which is usable as a dryer, has a working body-pan 1 with a variable step in two steps in height. Due to the presence of gaps, the material being dried is poured from one turn to another. A variable pitch and a different diameter of the coil of the working member determine a constant transnorting rate at each coil. For u.chshchshepi contact of all particles with the heating surface of the working body, increase the path, g / rohodim material, as well as the time of his sleep, the spillage of the material after each turn (shown in the drawing arrows). The heating elements 2 can be mounted on the inner side of the vertical vibratory transport) 3 and 3 hours directly on the lower surface of the working body along which the material moves.

Such a system mainly creates a contact method of drying, but due to the difference in temperature between the dryer and the surrounding air, there is also a convection method of sui: ki, and the design of the device of the vibrating dryer eliminates the need for sealing the loading and unloading.

PREPARATION AND RESULTS

1. Drying device for dry materials, narnmer but. They were either directly or directly in contact with greyun, its surface, heated with electric heaters, or convectively, containing a vertical conveyor belt, made in the form of a pipe with a screw-like working body with a uniform body and uniformly attached to it. its coils and decreasing lifting angle, which is communicated by oscillating motion with the help of a 5b rotor for non-displacement of the material being ejected from the bottom upwards from the loading hopper to the unloading one, differs from It means that with the simplification of the design and the contact of all the particles of material with the heating and surface of the working organ during the dynamic equilibrium of the transnorter, it doesn’t have an outer casing, and the screw surface of the conveyor is equipped with different partial transfer of material from one turn to another.

2.In the device but n. 1 location of electric heating elements on the inner surface of the conveyor pipe or directly on the lower surface of the working body, through which the dried material moves.
