Description

1. The prior art
The invention relates to devices for the production of decorative glass, obtained by processing the surface of the float ribbon with the reagent, and can be used in the production of Metelitsa glass.

 It is known that a device for the manufacture of float glass with a decorative surface (ed. St. 588726, MKI C 03 B 18/02) containing a melt bath and a gas distribution pipe with nozzles for supplying a gas reagent installed across the bath. The pipeline is placed in a water-cooled box equipped with longitudinal screens-partitions to ensure uniform supply of reagent across the width of the surface of the glass ribbon.

 This device allows you to get decorative glass "Metelitsa", however, when used, the pyrolysis products of the reagent gas are deposited on the walls of the screens in the form of solid precipitates that clog the passages between the screens, violate the reagent supply mode and, accordingly, the uniformity of the coating. On the surface of the glass ribbon, “bald patches” are formed in the form of elongated polished sections, which worsen the decorative pattern and reduce the yield.

 After three days, the equipment has to be removed from the molten bath and cleaned by tapping the device case.

 In accordance with another certificate of authorship (ed. St. 596553, MKI C 03 B 18/02, C 03 C 21/00), several pipelines are installed across the width of the melt bath in parallel with the aim of increasing the reliability of the device and the uniformity of the reagent supply to the glass ribbon surface to each other and at an angle to the longitudinal axis of the bath and to each of them reagent is independently supplied.

 But in this device, the nozzles of the pipelines become clogged over time and the uniformity of the reagent supply along the width of the glass tape is violated.

 Thus, these devices do not allow for a long time to receive a high-quality decorative coating.

2. The invention
The proposed device provides a stable mode of supply of the reagent to the surface of the glass ribbon and thereby makes it possible to produce decorative Metelitsa glass for a long time without additional cleaning of the equipment.

 The stability of the gas distribution device is achieved by the fact that the supporting water-cooled beam is equipped with a device for creating vibration. In this case, the beam is mounted on movable roller and spring supports.

 When using roller bearings, vibrational vibrations directed in the horizontal direction are applied to the supporting beam. When using spring bearings, the vibrator is mounted so that the vibration is directed vertically.

 A combination of roller and spring supports (or spring suspensions) is possible. The essence of the invention is to use vibration to give the device horizontal or vertical vibrations or a combination of them, causing constant shaking off of the pyrolysis products, clogging holes and passages.

 The frequency of vibrations can vary from 1 to 100 Hz, depending on the flow of the gas reagent and the duration of the equipment.

 As vibrators, electromagnetic, mechanical, pneumatic, and other types of vibrators can be used.

 In use, in which the gas passes through the guiding elements in the form of gratings, vibrational vibrations can be applied not to the entire housing of the device, but only to the gas distribution gratings.

3. The list of drawings
The drawings shown in figures 1-4 illustrate the reagent supply device in the production of glass "Metelitsa" in accordance with the invention.

 Figure 1 presents a General view of the location of the device installed in the bath of the melt; figure 2 is a cross section of a device located in the bath of the melt; FIG. 3 - an option for installing the device on movable roller bearings; figure 4 - installation of the device on the spring supports.

4. Information confirming the possibility of carrying out the invention
This invention is illustrated by the following examples.

Example 1
To obtain glass "Metelitsa" used device 1, located in the bath of melt 2 across the ribbon of glass 3 in front of the drowning machines 4 at a distance of 2-5 mm from the surface of the tin 5 (figure 1).

 The device shown in FIGS. 2, 3 consists of a water-cooled carrier beam 6, in which pipelines for supplying reagent 7 are placed. Pipelines 7 on the side of the glass tape are provided with holes 8 with a diameter of 1.5 mm, through which the gas reagent enters the processing chamber 9 and fed to the surface of the glass ribbon.

 The water-cooled beam 6 mounted on the roller bearings 10 is equipped with an electromagnetic vibrator 11, which transmits vibrational vibrations to the beam in a horizontal direction with a frequency of 50 to 100 Hz, which ensures constant shaking off of the resulting reagent pyrolysis products.

 As a result of a uniform supply of a gas reagent and an additional supply of pyrolysis products, a small relief pattern is formed on the glass surface uniformly located on the glass ribbon and is a combination of matte sections of the same size and glossy relief veins.

 Such glass is distinguished by higher aesthetic properties compared with other modifications of the "Metelitsa", which have a small pattern, but in which the relief is practically absent.

Example 2
In the embodiment shown in FIGS. 2, 4, a water-cooled beam 6 mounted on spring supports 12 is equipped with an electromagnetic vibrator 11, which transmits vibrational vibrations to the beam 6 in the vertical direction with a frequency of from 1 to 50 Hz. In this case, the same character and the same uniform distribution of the pattern are observed, i.e. spring supports and the vertical direction of vibrational vibrations can achieve the same patterning effect with less vibrator power.

 Thus, the proposed device allows to obtain high-quality decorative glass, ensures the duration of the installation and increases the yield of products.

 At the same time, the character of the formed pattern changes due to the additional influence of the precipitation products and vibration frequency, which allows expanding the range of Metelitsa glass.
