Description

The invention relates to the drying of granulated material in a gas stream. and can be used in installations to obtain a globular Ka- $ Chuka.

A device for drying globular rubber with nodes supplying coolant and powder composition [ΐ] is known. ten

A disadvantage of this device is: low intensity of drying of rubber globules.

A device for drying granulated material in stream 15 is known.

gas containing vertically installed pipes connected to each other by means of nozzles with fans in the lower part and with inclined grids blocking the cross-section of the pipes in the upper part

m ·

A disadvantage of the known device is that it does not provide the same drying conditions for 25 granules of different sizes, for example rubber globules, the size of which can vary widely, which reduces the drying efficiency of the material as a whole 30

The purpose of the invention is to ensure effective drying of the material, regardless of the size of the granules.

The goal is achieved by the fact that in a device containing interconnected via nozzles • vertically installed pipes with fans in the lower part and inclined grids in the upper part overlying the cross-section of the pipes, the grids are made swinging in a vertical plane, hinged on the walls of the pipes and provided with seals and mechanisms for controlling the angle of inclination of the gratings.

FIG. 1 shows a general view of the device; in fig. 2 shows section A-A in FIG. one.

The device contains vertically installed pipes 1 interconnected by means of nozzles 2, and a cooler 3 is installed at the outlet of the last pipe. In the lower part of the pipe 1 are installed fans 4, and in the upper part there are inclined grids 5 overlapping the cross-section of the pipes. For the supply of coolant Pre759329

branch pipes 6 are installed, and branch pipes 7 are used for removal of the spent coolant.

The gratings 5 are made swinging in a vertical plane, for which they are fixed to the pipe walls by means of hinges 8 and have seals 9. The gratings are connected through a shank 10 to a mechanism for adjusting the angle of inclination of the gratings. The latter is made in the form of a screw 11 with a nut, 12 connected to the handle 13.

The operation of the device is shown in the installation for obtaining globules of rubber. .

The latex coagulum continuously enters the bath 14, where, with stirring, rubber is released which is covered with a decohesion layer from the decoheeator 15 and passes to the surface of the vacuum filter 16, where it is powdered from the dusting device 17, washed out of the sprinklers 18 and wrung out from excess moisture with press rollers 19.

From the vacuum filter 16, the rubber enters through pipe 6 into pipes 1, where fan 4 is crushed into crumbs and picked up by coolant flow containing particles of dusting material suspended in it, and dried on grids 5. Transition from one pipe to another is carried out through pipes 2. Prepared rubber globules with packaging are cooled in the refrigerator 3. The position of the gratings 5 during the drying process changes

The mechanism for regulating its angle of inclination depending on the size of the crumb of the rubber supplied for drying.

The use of the invention will ensure a High drying efficiency of the material in the gas stream, regardless of the size of its granules, which will also increase the quality of the final product.
