Description

to load the mixture and battle in the glass melting night

The technical solution relates to the field of charge loading and battle in a glass melting furnace and can be used in the glass industry.

Specifically, the technical solution relates to the design of the glass charge loaders, in particular, the design of the table charge loaders.

As you know, loading glass melting furnaces is the most important operation in the production of glass. The reliability of the design of the loaders depends on the constancy of the level of molten glass in the furnace, as well as the correlation of the charge and battle of the raw materials introduced into the furnace, which ultimately affects the quality of the molten glass. In addition, the batch itself is a product with significant cost, and its rational use has a significant impact on the cost of production of glass.

The most common in the glass industry are the table top load and battle loaders as the simplest and most reliable in design. The main element in the design of these loaders is a table that is in constant reciprocating motion, moving the charge and battle into the furnace.

As the closest technical solution to the claimed is considered a typical loader ZSh-2, working on the principle of a tray feeder. A hopper is mounted on the loader frame, placed underneath on rollers

TABLE with a reciprocating drive. The table is made in the form of a tray, i.e. it has a horizontal inner surface and two vertical surfaces on the sides. The horizontal surface of the table blocks the bottom exit from the hopper, and the side surfaces cover the hopper on both sides. The wall of the bunker, facing the glass furnace, called the front, has a bottom cutout above the horizontal surface of the table. The opposite wall of the hopper, called the back, is lowered to the table and forms a gap with its surface, which serves as the main channel for the flow of the charge into the bunker space.

In the process, the table performs reciprocating movements and thereby ensures the supply of the mixture into the loading pocket of the glass melting furnace. D. PYA to prevent the loss of the charge into the bunker space in the constructions of the loader, a stationary seal is used in the form of a rubber strip across the width of the table (1).

However, it is quite obvious that with such a design of the seal it is impossible to ensure its effective compression against the movable table. When it is pressed firmly, resistance to table movement increases, which causes the drive motor to overheat and to use up energy for the bootloader to work. In addition, in this case, under conditions of constant contact with abrasive materials such as sand, soda, etc., there is intense wear of the rubber seal and a gradual increase in the gap between it and the table. With a loose preload of the seal, a gradual accumulation of part of the PCB behind the seal occurs and its discharge into the bunker

space at each reverse table stroke. In this case, the seal itself

prevents the return of the PCB to the process stream.

When unclaimed pshhty is poured onto the floor due to convective air flows from the furnace, it is sprayed in the atmosphere and environmental pollution. Ultimately, all this leads to direct losses of the PCB, which are 10-12 loaders in a single furnace with a productivity of 500-600 tons per day during continuous operation.

The objective of the new technical solution is to eliminate the loss of the charge and save energy.

The problem is solved in that in the known device for loading pschety and battle into a glass melting furnace containing a bunker of charge and battle, a frame with a drive placed on it, including an electric motor, gearbox, crank mechanism, reciprocating table on the support rollers and sealing element behind the hopper. The sealing element is equipped with an additional drive and is made with the possibility of synchronous vertical displacement at the extreme points of the reciprocating movement of the table.

The solution to the same problem is also facilitated by the fact that the additional drive of the sealing element comprises a cam disk, a roller, a rotary shaft and a system of levers, the roller being able to roll in a cam disk located on the shaft of the crank-crank mechanism of the table drive and provided on one side with a lever interacting with a spring mounted on the frame, and on the other hand, a second lever.

connected to a rotary shaft, which is rigidly connected to the sealing element.

The photo shows a general view of the device.

A device for loading a charge and battle into a glass melting furnace comprises a charge and battle hopper 1, a reciprocating table 2 placed under it, mounted on rollers 3 mounted on a frame 4. Table 2 is equipped with a drive consisting of an electric motor (not shown in the drawings) , gearbox 5, two-sided connecting rod and crank mechanism 6, located at the ends of the common shaft 7 and connected to the table 2. On the same shaft there is a cam disk 8 of the drive of the sealing element 9, interacting with the roller 10. The roller 10 is placed on the levers 11 and 12, and the lever 11 is connected to a spring 13 mounted on the frame 4, and the lever 12 is connected to a rotary shaft 14, which levers 15 are rigidly connected to the sealing element 9. The sealing element 9 consists of two metal plates 16, between which there is a strip 17 rubber. The loader frame 4 is mounted on the wheels 18, locked by the latches 19 on the rails 20. The charge 21 of the table 2 with the protrusion 22 is loaded into the loading pocket 23 of the glass melting furnace. The final part of the table 2 for the complete exclusion of the sifting charge is provided with a strap 24,

installed at an angle equal to the angle of repose of the charge.

A device for loading a charge and battle into a glass furnace works as follows.

From the principle of operation of the device of this design, it follows that when the table 2 moves forward (to the furnace), the charge 21 is loaded onto the table, and when the return is made, the charge is unloaded into the pocket 23 of the glass melting furnace. It is absolutely obvious that, in terms of the charge loss, the greatest danger is represented by the reverse stroke of the table 2, during which, due to the gap between the table 2 and the hopper 1, a layer of the charge remains on the table, which is subject to pouring into the bunker space. In this regard, the end points of movement of the table 2 are, in one case, the beginning of the cycle of loading the mixture onto the table, in another - the beginning of the cycle of unloading the mixture into the furnace.

When the table 2 moves forward (shown by the arrow), the charge 21 is spontaneously dumped from the hopper 1. In this case, its distribution is more or less uniform in height along the length of the table 2. The movement of the table 2 is provided by a drive, the gearbox 5 of which rotates the shaft 7 from the electric motor, the ends of which are two connecting rod-crank mechanisms 6, converting the rotation of the shaft into the reciprocating movement of the table 2, with which they are connected. When the table 2 moves forward, the sealing element 9 is raised up due to the fact that in this case the roller 10 rolls around the circular surface of the cam disc 8, and the levers 11 and 12 and the rotary shaft 14 are stationary. Thus, when the table 2 moves forward up to the extreme point of this movement, the sealing element 9 is in the upper

5 position. Upon reaching this point, the crank mechanism 6

completes the revolution, and the roller 10 falls on the curved surface of the cam disk 8. Table 2 stops and begins to move back, while the spring 10 pulled through the lever 11 rolls around the curved surface of the disk 8 and through the lever 12 rotates the rotary shaft 14, rigidly connected to the sealing element 9. Cozy element 9 goes down and covers the table 2 in width, preventing the penetration of the charge to the edge of the table. At the same time, to prevent the penetration of the charge beyond the sealing element 9, both the strip of rubber 17, providing a complete delay of the particles of the charge on the table surface, and the metal plate 16, preventing; To completely eliminate this, on the rear edge of table 2 there is a bar 24, which is installed with a slope towards the rear wall of the hopper 1, equal to the angle of repose of the board.

Thus, the reverse stroke of the table 2, corresponding to the cycle of loading the charge 21 into the loading pocket 23 of the furnace, occurs when the sealing element 9 is lowered. The sealing element 9 is lowered while the roller 10 rolls around the curved surface of the disk 8. As soon as it enters the circular surface of the disk 8, the sealing element 9 rises, and the table 2 begins to move forward (towards the furnace).

The tight pressing of the roller 10 to the cam disc 8 is provided by a spring 13 mounted on the frame 4.

The wheels 18 of the frame 4 are locked with clamps

prevent the bootloader from shifting during operation and provide adjustment of the bootloader position relative to nothing.

As follows from the description of the loader, its design provides complete prevention of the loss of the charge when it is loaded into a glass furnace. In addition, the pilot operation of such a loader at the Borsky glass factory revealed significant savings in the energy spent on its operation.
