Description

The invention relates to the glass industry, primarily to devices for charging the charge and glass to electric glass melting furnaces, the cooking part of which is covered with a vault and its shape is close to the circumference.

The aim of the invention is to reduce power consumption and improve the quality of glass mass due to uniform distribution of the charge.

FIG. 1 shows the proposed - 1NY batch loader, general view; in fig. 2 - kinematic scheme of the charge loader.

The charge loader consists of a hopper 1, an anism mechanism 2 of the charge mixture, made in a vibrating channel, a vertical shaft 3 with a charge distributor mounted on it consisting of funnel 4 and a tray 5. The charge loader is installed above the roof 6 of an electric glass melting furnace 7 on frame 8 ..

The lower end of the vertical shaft 3 with the funnel 4 and the tray 5 through the hole 9 in the roof 6 is installed directly in the gas space of the furnace 7. The funnel 4, made in the form of a beveled truncated cone and installed between the metering mechanism 2 and 2 tray 5, contributes to the continuous supply of the Wich from the mechanism 2 dosing in the tray 5 at any position in the space of the furnace.

Tray 5 is mounted on a vertical shaft 3 with the ability to change the angle of inclination. The change in the angle of inclination is achieved by the fact that the tray 5 is mounted on hinges 10, 11, one of which 10 is fixed at the lower end of the vertical shaft 3, and the other 11 through tgu 12, the hinge 13 and the bearing assembly 14 - at the lower end of the rod 15. Vertical shaft 3 is hollow. The rod 15 is installed in the cavity of the vertical shaft 3 with the possibility of reciprocating movement from an additional drive, kinematically connected with it, consisting of a gearbox 16 and an electric motor 17.

The vertical shaft 3 is connected via a worm gear 18, a propeller shaft 19, and a gearbox 20 connected to an electric motor 21. An electric motor 21, and therefore also lotto 5, has pos217790. . J

This is the rotation speed. The upper end of the rod 15 is made in the form of a screw 23 and is engaged with a nut 23, which is simultaneously the 5th hub of the sprocket 24. The latter, through a chain transmission 25 and a gearbox 16, is connected to an electric motor 17-DC, the speed of rotation of which is controlled by software 10 device (not shown).

. Batch loader works as follows.

 The mixture from the hopper 1 is fed through the metering mechanism 2, in this case the vibrating channel, through the funnel 4 to the tray 5, through which it is poured onto the surface of the glass melt. At the same time, the electric motor 21 is switched on, which ensures the rotation of the vertical shaft 3 with the funnel 4 and the tray 5 fixed on it, and the electric motor .17, which ensures the movement of the tray 5 by changing its angle of inclination. Consequently, the path 5 makes two movements: rotation around the circumference and a change in the angle of inclination, while the lower end of the tray 5 moves in a spiral.

A software platform (not shown) controls the motor 17, providing a tight arrangement of the turns distributed by the tray 5 of the charge, resulting in a uniform coating of the surface of the glass melt by the charge.

Under the condition of cooking in electric furnaces with a different arrangement of electrodes, it becomes necessary to change the thickness of the mixture on the surface of the glass melt. For example, the maximum thickness of the layer of the charge is located on 1/3 of the radius from the walls of the cooking part, either in the center or along the walls. . Software control of the motor 17 makes it possible to positively resolve this issue.

When loading the charge with the loader, the entire surface of the glass melt in the cooking zone of the electric furnace is evenly covered with a layer of the charge, which excludes the effect of burnout.

As a result, the power consumption for glass melting is reduced, its homogeneity increases, and consequently, the quality of glassware,
