Description

A glass kiln feeding equipment capable of automatic weighing

technical field

The invention relates to the technical field of glass production and processing equipment, in particular to an automatic weighing glass kiln feeding equipment.

Background technique

In the glass production process, it is necessary to send the well-proportioned materials to the glass furnace for melting, so the feeding stability of the production materials has a great influence on the quality of the glass liquid made in the furnace. Specifically, if the feeding accuracy is high, it can ensure that the material mountain in the kiln is evenly distributed and the liquid level is stable, so that the temperature of the glass liquid can be maintained in the optimal reaction range; if the feeding effect is good, the mixing uniformity of the materials can be ensured. In turn, the quality of the final glass product is more standard; therefore, only when the feeding equipment or feeding method achieves higher feeding accuracy and better feeding effect, can a good glass melting quality be achieved.

However, most of the current glass melting workshops use manual feeding; this method is prone to defects such as unstable feeding speed, non-standard feeding amount, and uneven material mixing effect in actual use. If the feeding speed is unstable or the feeding amount is not standard, the glass liquid level in the glass furnace will fluctuate, which will lead to unstable pressure and temperature inside the furnace, thereby affecting the melting effect; and under the fluctuation of liquid level , the refractory material on the inner wall of the kiln will be repeatedly scoured by the glass liquid. In the long run, the furnace wall may be corroded and burned through, which will reduce the service life of the kiln and create a safety hazard in the glass melting process. . If the material is not mixed uniformly, it will directly affect the quality of the glass product, that is, the quality of the resulting glass product will be reduced. In addition, although there are also a small number of workshops that use feeding equipment for feeding, such equipment is often only composed of simple structures such as feeding bins, feeding bins, and feeding pipes. The working accuracy and feeding speed cannot be controlled, so there are also defects in the manual feeding method, which cannot meet the actual production needs, thus seriously affecting the improvement of glass production efficiency.

Contents of the invention

The object of the present invention is to provide a glass kiln feeding equipment that can be automatically weighed to solve the problems of unstable feeding speed, non-standard feeding amount, and material mixing effect in the prior art due to manual feeding methods or simple feeding equipment. Inhomogeneity and other defects lead to poor glass melting effect, the quality of glass products cannot be guaranteed, and the service life of the furnace is affected.

The present invention is realized by adopting the following technical solutions:

In actual use, above the feeding device is a feeding device such as a screw conveyor, which is also electrically connected to the controller, and the material can be transported to the storage bin at a specified speed; the storage bin is used to transfer the material , and some processing can be performed on the material, and then the material in the storage bin will reach the feeding trough; the weighing mechanism in the feeding trough can carry out real-time weighing on the dynamically entering material, when the weight of the material reaches a predetermined value, the weighing The heavy mechanism will link the feeding equipment through the controller to stop the feeding, thereby ensuring the standardization of the feeding amount. The above process does not require manual operation and judgment, so that there is almost no error in the feeding amount or the error is within an acceptable range. When the weight of the material reaches the set value and the feeding equipment stops feeding, the weighing mechanism will release the material to the feeding pipe group, and the material will enter the kiln through the feeding pipe group and blown by the fan; therefore, the feeding device The feeding action is based on whether the weight of the material reaches the standard as the start-stop signal, and under the premise of a certain feeding speed of the unloading equipment, the conveying length of the feeding pipe group and the power of the fan, the feeding speed is stable. In addition, the material entering the feeding pipe group will be blown by the fan.
