Description

The utility model relates to the glass industry, namely to the production of high-quality glassware, in particular to the production of colored glass.

A device is known for painting and mixing glass melt in a continuous flow, containing a chamber attached to a glass melting furnace with a feeder for dye and electrodes in the bottom, characterized in that, in order to improve the quality of the glass melt and reduce dye losses, a screw mixer with opposite screws is installed in the chamber of the device. stroke, the axis of which coincides with the direction of the vertical downward production flow of glass melt, and the feeder for the dye is made in the form of cooled spray nozzles and is equipped with a concave reflector (SU 224760 A1, published 12/08/1968).

The device has a number of disadvantages: low operating efficiency, as well as high energy costs during operation of the device.

The system for coloring glass melt in the feeder channel is today widely used for the production of glass containers, bottles for cosmetics, high-quality glassware, and glass for architectural objects. The technology of coloring the glass melt with colored frits in the feeder channel allows for greater flexibility and production efficiency. When using this method, less dye is consumed and it becomes possible to change the color of products quite flexibly.

To obtain the required shade, varying amounts of colored frit in granules are introduced into the glass melt as a dye. To obtain uniformly colored glass when granulated colored frit enters the feeder channel, special mixers made of heat-resistant materials are provided, with the help of which the frit is mixed with the glass mass until a uniform color is obtained.

Colored frits are low-melting granules measuring 2-5 mm. Various combinations of oxides of Co, Cr, Cu, Ni, Mn, Fe and other metals are used as coloring components, which makes it possible to obtain a wide palette of shades (http://www.rusceram.ru/production/okrashivanie-steklomassy/cvetnaya-fritta /).

The claimed glass mixing machine is designed for mixing finely dispersed dyes (frits) with glass melt in the feeders of glass furnaces. The main task of the machine is to homogenize the dye in the transparent glass, followed by a uniform change in the color of the glass.

The design features of the proposed machine allow it to be used at high temperatures and, most importantly, installed directly in front of the droplet formation mechanism. Which in turn makes it possible to significantly reduce the length of the feeder, and as a result simultaneously obtain different colors when producing glass products from one glass melting furnace.

The purpose of the utility model is to expand the design features of a device for mixing and coloring glass melt.

The technical result consists in the ability to simultaneously obtain different colors when producing glass products from one glass furnace. Coloring occurs immediately after the frit enters the feeder with a gradual color change, which allows you to choose any shade/tone of color.

The technical result is achieved by the fact that a device for mixing and coloring glass melt (glass mixing machine) is proposed, containing a common frame (item 4), which is attached to the feeder (item 12) with brackets (item 5);

a movable subframe (pos. 6) is installed on the frame, on which a traverse (pos. 3), a winch (pos. 8), a cable (pos. 7) are installed, while the traverse is installed with the ability to move up and down using a winch (pos. 8) and cable (item 7);

Ceramic stirrers (item 1), a cooled chain mechanism (item 2), a gear motor with a variator (item 9) are mounted on the traverse, while the ceramic stirrers are driven by a cooled chain mechanism (item 2) and a motor -gearbox with variator (item 9).

Ceramic stirrers (item 1) have a special helical tip geometry and rotate in opposite directions up to 36 rpm.

Description of the device operation

Transparent glass is produced in a glass melting furnace and through the feeder (Fig. 2, item 12) flows by gravity to the drop formation mechanism. The frit for coloring is dosed by a separate device and supplied by pneumatic transport to the feeder and transparent glass.

The glass mixing machine (Fig. 2, item 10) is installed on the feeder of the glass melting furnace (Fig. 2, item 12), ceramic mixers (Fig. 1, item 1) are immersed in the moving glass mass (Fig. 2, item 11) at temperatures up to 1500° WITH. Ceramic stirrers (Fig. 1 item 1) with a special helical tip geometry rotate in opposite directions up to 36 rpm. They are driven by a cooled chain mechanism (Fig. 1, item 2) and a gear motor with a variator (Fig. 1, item 9). All this is secured to a traverse (Fig. 1, item 3), which moves up and down using a winch (Fig. 1, item 8) and a cable (Fig. 1, item 7). This is necessary for adjusting the immersion depth and maintaining/replacing ceramic stirrers. The traverse (Fig. 1, item 3) is installed on a movable subframe (Fig. 1, item 6), which ensures its movement to the side for maintenance/replacement. All structural elements are fixed to a common frame (Fig. 1, item 4), and the frame is attached to the feeder (Fig. 2, item 12) with brackets (Fig. 1, item 5.)

The time for coloring glass melt depends on the volume of glass flowing through the feeder (removal), on the size of the feeder and on the color of the frit, and can vary from 5 hours to 10 hours.

The main advantages of this useful model compared to analogues are: the possibility of use in environments (including glass) with temperatures up to 1500°C. Coloring occurs immediately after the frit enters the feeder with a gradual color change, which allows you to choose any shade/tone of color. The coloring process is continuous and allows the production of up to 30 tons of colored glass melt per day.
