Description

one

The invention relates to devices for the continuous vulcanization of long polymer products and is intended for the vulcanization of products made of spongy material in a fluidized bed.

A device for the continuous vulcanization of long-dimensional products IB is known in a nonsustainable layer containing a bath filled with a granular coolant, a gas distribution grid, a system: supplying a fluidizing agent and a release agent tank installed in front of the curing bath. However, the known device does not provide the proper quality of products made of spongy material, since the release agent in it is applied to the product and the vulcanization bath, and during the vulcanization process, noration occurs and the product increases in volume. As a result, a part of the surface of the product remains without a release coating and particles of a granular coolant adhere to it, which degrades the quality of the product.

It is necessary to install a container with a release agent over the gas distribution grid B in the vulcanization bath at its entrance section and to perform with a flexible bottom.

On fng. 1 shows the device described, FIG. 2 shows the device, section A-A in FIG. one.

The device for continuous vulcanization contains a vulcanization bath 1 filled with a granular coolant | M 2, a gas distribution grid 3 with nozzles 4 for supplying a fluidizing agent, and pulling rollers 5 and 6 for moving the vulcanized product through a volcanic wane. At the inlet section of the bath 1 above the gas distribution grid, a closed container 7 with an anti-adhesive 8 is installed, which prevents the particles of the granular heat transfer medium 2 iK from being vulcanized.

Capacity 7 is immersed in a fluidized bed of granular coolant and is made with a flexible dnshets.

A vibrator 9 is installed in the container 7 on the output section of the section to vibrate excess adhesive from the product. A similar vibrator 10 is also installed at the outlet of the bath 1 for removing particles of the granular coolant from the isdeln.

When vulcanization is carried out into the bath 1 through the pipes 4 and the gas distribution grill 3, a heated gas is supplied, which vaporizes and fluidizes the granular coolant 2. With the help of pulling rolls 5 and 6, the vulcanized article 11 is charged into the bath.

Under the action of the bogging coolant 2, the flexible bottom of the tank 7 is vibrated, heating ii intensive mixing the release agent doesn’t have an anti-adhesive 8. As a result, the raw product 11, passing through the tank 7, is heated to dry the pore formation, increases to the size of the finished product and at the same time covered with adhesive: over the entire surface. In this case, a partial vulcanization of the article from the surface also occurs. The basement of the Canazic surface thin elephant prevents damage to the product during the subsequent interaction of ic by the granular coolant 2 as it passes through the latter.

With the vibrator 9 at the exit of the product from the container 7, excess anti-adhesive 8 is spun from it. Then the product is passed through a layer of heat transfer medium 2, where it is vulcanized into a foil. At the exit of the bath 1 with 1pedon, the particles of the coolant flow from the product to the vibrator 10. Next, the finished product is removed from the bath 1 and is fed to the following process steps.
