Abstract

The invention relates to a glass industry, mainly for loading the charge in an electric glass melting furnace. The purpose of the invention is to increase the stability of the device by preventing the charge from sticking to the blades of the metering drum. The device for loading the glass furnace contains a hopper 3, a screw auger 5, a drum in the form of a shaft mounted under the longitudinal groove of the auger body with radial blades, enclosed in the body 6 and mounted for rotation from an individual drive 9. The blades of the metering drum are made of elastically deformable material. In the lower part of the casing 6 of the drum, stops 11 are installed, which interact with the blades when the drum rotates. The stops can be made adjustable. The device will eliminate the periodic cleaning of the metering drum from adhering charge. 1 з.п, ф-лы, 3 1Ш. S 1. 0: 5 with //////// 7 // //. 1m

Description

Fg / 8.1

The invention relates to the glass industry, in particular to devices for charging the charge to smelting furnaces, mainly electric glass melting.

The purpose of the invention is to increase the stability of the operation of the device by preventing the charge from sticking to the blades of the metering drum.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - node I in figure 2.

Device for loading glass 10

, the length of the body 4, and the shaft 7 with radially arranged blades 8 during the movement of the carriage 1 evenly distributes it over the surface of the cooking part of the oven. When the drum rotates, the blades 8 are successively touched by the stops 11 located in the lower part of the barrel 6 of the drum, and are elastically deformed. After passing the stops, the blades are released, making damped oscillations. At the same time, the charge on the blades is separated and poured out into the lower groove of the dosing furnace housing of the stove. The furnace contains a movable trolley 15 Raban 6. The magnitude of the deformation of the blade

cu 1 moving along the loading window of the furnace with the help of drive 2. On the trolley 1 there is mounted a hopper 3 connected to the case 4, in which a screw auger 5 is installed. The screw outlet is made in the form of a longitudinal groove located in the lower part of the case 4 equal to the cooking part of the stove. A metering drum, made in the form of a shaft 7 enclosed in an individual case 6 with radially arranged longitudinal blades 8 mounted rotatably from an individual drive 9, is installed under the auger case. The blades 8 have the shape of a corner, made, for example, of wear-resistant steel and attached to the shaft 7 with screws 10.

In the housing 6 at the lower groove there are threaded adjustable stops 11 distributed along the length of the housing with a certain pitch. Screw auger 5 receives rotation from the actuator 12. The drum housing is made with upper and lower longitudinal grooves, with the upper communicating with the longitudinal groove of the housing 4 of the screw auger 5.

The device works as follows.

At the initial moment, on command from the control panel (not shown), the actuator 12 is turned on, the screw auger 5 begins to rotate and the housing 4 is filled with the charge. As soon as the hull is filled with Schichtoy, the actuator 12 is turned off. Then, a command to load is given by a command from a level gauge or from a control panel (not shown). Drives 12, -9 and 2 are switched on. Screw 5 feeds and distributes the charge throughout

, the length of the housing 4, and the shaft 7 with radially arranged blades 8 during the movement of the trolley 1 evenly distributes it over the surface of the cooking part of the furnace. The blades 8, while rotating the drum, successively hit the stops 11, located in the lower part of the drum body 6, and are elastically deformed. After passing the stops, the blades are released, making damped oscillations. At the same time, the charge on the blades is separated and poured out into the lower groove of the dosing ba casing.

the current, as well as the amplitude of subsequent oscillations, can be varied with the help of adjustable stops 11. In the final position, if there is a command from the level gauge to stop loading, trolley 1 stops and all drives are turned off. In the absence of a command from the level gauge to stop loading, the trolley 1 changes the direction of movement and the next charge charge cycle occurs.

The use in the metering drum of elastically deformable blades and adjustable stops located in the lower part of the casing of the metering drum, interacting with each other, allows to stabilize the charge loading uniformity and eliminate periodic cleaning of the metering drum from adhering charge. This in turn ensures uniform boiling of the glass melt, which ultimately leads to an increase in the productivity of the furnace.
