CS213818B1 - Apparatus for simultaneously loading strandular and bulk materials,especially glass fibres and glass batch - Google Patents

Description

BACKGROUND OF THE INVENTION The present invention relates to a device for loading fibers together with bulk material, in particular, non-lubricated glass fiber waste together with a glass batch, or glass fibers together with a batch and a glass holder, into a bath melting unit.

In the production of glass fibers by drawing, otherwise poorly usable waste is produced, which can be sorted into non-lubricated and lubricated waste. The non-lubricated portion of the waste is poorly processable in the melting of the glass fiber, where a glass batch and the non-lubricated glass fiber waste can be fed to the melting aggregate to a certain extent, while maintaining the quality of the melted glass. This glass fiber waste, as an easier fusible component of the batch, partially replaces the necessary shards, i.e. frit or glass pulp.

The USSR Certificate No. 518 468 addresses the simultaneous loading of glass pulp with a piston dispenser and a glass batch with a turnstile dispenser into a closed gobé. The easier fusible component is fed underneath the trunk by a common reciprocating piston device.

USSR Author Certificate No. 300 421 solves the separate loading of glass pulp by a vibration continuous feeding and the glass batch by a turnstile feeder, into an open gobo, while a lighter melting component is charged under the batch.

USSR Author Certificate No. 368 191 solves separate foundation. glass pulp with a tur213 818 * 13 818 nickel dispenser, which is continuously fed by a vibration yarn, and the glass batch also with a turnstile dispenser, into an open gobo. The lighter fusible component is below the batch.

USSR Author Certificate No. 289 976 provides for the foundation of a glass batch by means of a piston dispenser and pre-melted batch waste, via the vertical shaft preheating of the two components, to. bathtubs.

U.S. Pat. 1,471,866 deals with the establishment of only a trunk.

U.S. Pat. 2,442,461 solves the foundation of only a stem with a melting point.

A common disadvantage of the above solutions is that they are not usable for loading fibrous materials. Another drawback is the relatively high complexity of the devices and the related demands on their operation and maintenance.

These disadvantages are overcome by the device according to the invention intended for the simultaneous loading of fibrous and loose materials, in particular glass fibers and a batch of glass, which consists in dividing the hopper into a fibrous and loose material part and also guiding the piston on the rails by wheels. simultaneous loading of both materials by placing these wheels above the piston.

To reduce the losses of mainly bulk materials, the plunger is sealed to the side and bottom forming the foundation chute.

The present solution achieves the loading and dosing of the fibers simultaneously with the bulk material, in particular unpretected, i.e., unpretentated, i.e., unloaded. the non-lubricated fiberglass waste by direct loading into a bath aggregate along with a glass batch containing also glass pulp.

There is no need for the pre-treatment of the fiber such as baling, reflow in the refuse oven and subsequent frying, or manual feeding into the melting furnace is necessary. In addition, the direct introduction of fibrous waste reduces the demands on the raw materials forming the charge and saves energy. In the following, the device allows the loading of up to 20% of the fibers based on the weight of the strain, or it can load only the strain itself. The device is relatively easy to operate and maintain.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The description and schematic drawings of an exemplary embodiment show more details. radiation according to the invention. In FIG. 1 is a front view of the device, and FIG. 2 in side view.

The stacker consists of a two-part hopper 1, divided into parts 14 and 15, of a stacking piston 2 guided on the rails 3 by means of wheels 14 positioned above the piston 12. The loading piston 2 is sealed against the side walls 5 and the bottom JS forming the foundation trough. The piston 2 is driven by a hydraulic oil pressure cylinder 7 from a standardized unit 8. The stroke and movement of the piston 2 is controlled by end stops 9, 10, an electromagnetic distributor 11 and the speed is continuously adjustable from zero to maximum by a throttle valve 12. it is possible to connect a water oil cooler 13. The space between the stacker and the melting aggregate is bridged by a flip-off chute 16.

The operation of the stacker is as follows: The batch is fed into part 14 of the hopper 1 and the glass fiber waste into part 15 of the same hopper 1. This mixture falls in the starting position in front of the piston 2 which feeds it into the melting unit via the flip trough 16. fiber and protects it from premature melting.

In the case of a suitable solution of the split container, the glass fiber waste treatment process could be completely mechanized or automated.
