Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions in the embodiments of the present invention will be clearly and completely described in the following in conjunction with the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 5 to 8, a preheating bin 1 of a preheating device for a kiln head 6 of a glass annealing kiln in the embodiment is arranged at the top of the kiln head 6 of the annealing kiln, an internal cavity is divided into two preheating sub bins 2 along the direction perpendicular to the bottle conveying direction of the annealing kiln, a bin cover 3 capable of opening and closing is arranged at the top, the bottom is in direct contact with the top of the kiln head 6 of the annealing kiln, a hanging basket 4 matched with the external dimension of the inner cavity of the preheating sub bins 2 is accommodated in the preheating sub bins 2, and can be lifted up and down by a micro-aerial vehicle 5 arranged above the preheating bin 1;
the kiln head 6 assembly is formed by a preheating device and an annealing kiln head 6, and heat preservation cotton is arranged on the side wall of the kiln head 6 assembly for heat preservation.
In a specific implementation, the corresponding structure arrangement also includes:
The bottom of the preheating bin 1 is a fence-shaped structure formed by arranging a plurality of steel bars 7 at intervals, and if the operation safety is considered, a layer of iron sheets can be paved at the lower part of the steel bars 7.
One side of the bin cover 3 perpendicular to the bottle conveying direction of the annealing kiln is hinged to the top end of the side wall of the preheating bin 1, and can be turned around a hinge shaft to open or close the preheating bin 1.
The upper end of the middle part of the preheating bin 1 is provided with a cross rod 8, and the preheating bin 1 is divided into two preheating sub-bins 2 through the cross rod 8.
Fig. 9 shows a mould basket 4, which basket 4 is manufactured in such a way that it is required to accommodate 7-8 moulds at a time, the total weight being about 150-200 kg after full loading.
As shown in fig. 7 and 8, the micro-aerial vehicle 5 uses a pair of symmetrically arranged brackets as a support frame and can horizontally move along the bottle conveying direction.
Figures 2 to 4 show a first section of annealing kiln 9 and a portion of a conventional kiln head 6, between which a shutter 7' is arranged, which serves to block heat loss from the kiln. However, in actual production, there is a gap between the bottles and a gap between the bottle mouth and the shutter, so that heat loss is inevitable. Further, when the hot glass bottle enters the lower part of the kiln head 6, a part of heat is substituted, so that the temperature of the hot air in the lower part of the kiln head 6 is relatively high, and the part of heat is dissipated to the atmosphere even if not used. This provides the possibility for the invention to prepare a preheated mould in the upper part of the kiln head 6.
