Device for moistening a glass batch flow

The innovation relates to a device provided with an essentially horizontally arranged conveyor line for moistening a preferably continuous glass mixture flow with the aid of spray nozzles.

Glass batches, for example those that can be vitrified for agglomeration Batches are conveyed on a conveyor line, must be suitably homogenized and prepared be moistened. As is known per se, the moistening is carried out by using spray nozzles flowing glass batch, for example on a conveyor belt, is sprayed with water from above. This type of humidification has however, the disadvantage that the moisture penetration does not take place uniformly. It is true that the surface of the glass batch flow becomes strong soaked, the moisture does not sink into the depth, but primarily wets the surface. It is therefore It is necessary to carefully shovel over such glass batches again before they are given to agglomerate.

It is therefore the task of specifying a device in which a very precise and uniform distribution of moisture takes place reliably within the entire glass batch.

It should also no longer be necessary to use the goods after the Stir through moistening again mechanically.

According to the innovation, this object is achieved in that the device for moistening the glass batch flow has a falling edge is present at the end of the conveyor line, from which the mixture falls over a drop section, and at least there is a spray device arranged in the area of the drop section of the mixture and aimed at the falling mixture. The device according to the innovation is based on the principle of supplying the batch flow to a drop step. That is in free fall The mixture present has a loosened structure, i.e. no tight packing, so that the sprayed-in liquid is Can penetrate mixed flow. Depending on the type of batch, a second conveyor line may then be switched on A calming stretch for better distribution of moisture can be, but usually the mixture falls directly into one Further processing machine or is otherwise removed.

The spray device is preferably arranged such that the jet between 50 and 100 mm below the falling edge of the Conveyor line hits the mixture. In this area, the mix has the right speed and structure for the cheapest To achieve moisture penetration.

As already indicated, both for-

derbands as well as vibrating plates can be arranged. Preferably, vibrating plates are used that do not rotate Have parts and are therefore less maintenance-prone. Such vibrating plates can be rigidly connected to one another, thereby simplifying their drive. You can also be rigidly connected to a housing, the dust flight and the like prevented.

Furthermore is possible on the front and back of the falling Arrange mixed spray nozzles. As a result, the falling mixture can be a little thicker, which increases the capacity.

Finally, it is possible to design the conveyor line as a closed oscillating box with only a filling and discharge opening to design.

It is also proposed above the upper vibrating plate to attach a layer height limiter so that the device can be adapted to any performance requirements and batch compositions can be customized.

Embodiments of the innovation are shown in the drawing. The figures show:

Figure 1 schematically shows a side view of the device according to the innovation in a first embodiment; FIG. 2 shows a plan view of the device according to FIG. 1; Figure 3 schematically shows a side view of another embodiment

-A-

FIG. 4 shows a plan view of the device according to FIG. 3.

The device according to FIGS. 1 and 2 consists of a vibrating trough 3 with a base plate 4, below which a vibration exciter 1 is installed. The base plate is connected to the upper edge delimitation 5 via struts, walls and the like. Furthermore, there is an outlet channel 6 which is attached to the end of the base plate 4 and has an opening for free fall downwards. Furthermore, a batch funnel 10 is attached to the edge delimitation at the beginning of the vibrating plate, into which the batch 11 is poured. It then moves over the vibrating base plate 4 in the direction of the outlet channel 6. The vibrating trough 3 is connected to brackets 9 ^{via supports 8 and elastic cushions 8 1.} The consoles are attached to the sides of walls (not shown). As is known per se, the entire vibratory system moves with a certain frequency, so that the mixture is promoted.

The conveyor line is arranged essentially horizontally and has a falling edge where the outlet channel 6 begins 12, from which the mixture falls over a downward path. In the area of the drop section, there are spray nozzles aimed at the mixture 20, 21 arranged, which spray water into the falling mixture. The spray devices are arranged such that their beam between 50 and 100 mm below the falling edge that

Mixture hits. The moistened mixture then falls into a further processing machine, onto another conveyor belt or like that. By arranging two spray nozzles on the front and back of the falling mixture, a larger Thickness of the mixture to be moistened. Overall, it is possible for the oscillating system, in particular the oscillating trough, to be on all sides to design a closed structure or as a laterally open channel.

In Figures 3 and 4 is another Ausführungsforiti the innovation according to the invention Device shown. It has a base plate 17 on which elastic supports 14, 14 ″ are built are, as they are generally known from vibration engineering are. The supports 14, 14 'carry an upper swing plate 13, lower vibrating plate 18 and an existing vibrating element. The vibrating element is over the supports (Consoles) and connected to a hood 23 via side walls 22. The batch hopper 10 protrudes through the hood, into which the glass batch is to be poured.

At the same time, the hood is a known vibration exciter 1 connected, which makes the elastically mounted parts vibrate, for example with an eccentric motor. Moreover a layer height limiter 2 is built into the hood 23, which is adjustable and to the required performance and the respective batch structure can be set, whereby a uniform height is achieved in each case. One of those

Layer-height is even with the apparatus of FIG \ 1 and 2 are provided (reference numeral 2). \

Below the upper oscillating plate, in the area of the connection \

between the upper and lower plate, there is a spray;

falling batch 11 directed. The spray nozzles are designed in this way arranges that the spray jet should be between 50 and 1CXD mm below Ij the falling edge hits the mixture. - ■ .1

The function of the device is therefore as follows:

The mixture located in the batch hopper 10 is caused by the constant oscillation of the two arranged in parallel, in Direction of conveyance and vertically offset oscillating plates 13, 18 promoted on the upper oscillating plate, the height through the layer height limiter is limited. As soon as the mixture reaches the end of the upper vibrating plate, it falls down and is hit by the spray jet and soaked thoroughly. The amount of water supplied is of course variable and to adapt to the respective mixture present. The actual water supply is not shown. Due to the even Swinging, a constant conveying speed and thus the amount of fall per unit of time is maintained. The

Moistened mixture falls onto the lower oscillating plate 18 and is continuously conveyed on it to the outlet 24. It then falls down and is sent for further processing. The conveyor line acts on the lower oscillating plate as a kind of calming section for better distribution the existing moisture.

Instead of vibratory conveyors, you can. of course also Conveyor belts are used without leaving the scope of the innovation. While the function of the device according to the innovation Accordingly, the upper and lower vibrating plates as well as the housing vibrate synchronously, since the vibrating plates are mutually and are rigidly connected only to the housing.

It has been shown that a glass batch flow, consisting of finer and coarser batches as well as shards, is evenly moistened can be.
