Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a short glass fiber collection device that collects dispersed glass wool in the form of a mat by fine fiberizing molten glass using a glass fiberization device. The purpose is to improve the quality of both sides of the collected glass wool mat in the width direction, and to make it possible to modify the short glass fiber collection device to improve the suction efficiency of the glass wool dispersed cotton. .

A perforated air filter device is placed below the glass fine fiber fhi device for turning molten glass into fine fibers, and a suction negative pressure is applied from below the device, and the fibers of the glass wool dispersed in the device are collected. For example, a short glass fiber collecting device a in which side wall members for controlling the width of the glass wool mat to be collected and deposited are arranged on both sides of the width direction of the depositing area 1 is used.
The one shown in Publication No. 5-506.1, Tokko Sho LL
The one shown in Japanese Patent No. 8-38351 is well known.

However, these known structures are 111! l
The wall member is constituted by rotating side walls that continuously move like an endless belt on both sides in the width direction of the collecting and depositing area of the glass wool dispersed cotton of the perforated conveyor device, and said cotton collecting.

In the deposition area, droplets or clumps of binder or agglomerates of glass wool dispersion adhering to the surface of the rotating side walls are
The short glass fibers are removed at the outside of the collection device. That is, the rotary side wall is covered with droplets or lumps of binder or agglomerates of dispersed fibers of glass wool.11 At a position outside the collecting and depositing area of the perforated conveyor device, an endless stream is formed outside the device. It is designed to be inverted like a belt and remove deposits on the outside of the device.

As mentioned above, in order to invert the rotating wall to the outside of the apparatus to which droplets or lumps of binder or agglomerates of dispersed cotton of glass wool are attached, the front and rear ends of the cotton collection and deposition area are restricted. It is necessary to leave a gap of several millimeters between the edge of the weir wall that is turning over and the pivoting side wall that is turning over so that the deposits can pass through.

By the way, in the cotton collection and deposition area, a suction box opens below the perforated conveyor belt, sucks the atmosphere in the area through the perforated conveyor belt, and transfers the dispersed cotton of one glass wool onto the perforated conveyor belt. In order to improve the suction efficiency of the suction box, the gap between the dam wall and the rotating side wall must be extremely small, or the gap between the dam wall and the rotating side wall must be extremely small. Preferably, the movable side walls are in sliding contact with each other.

However, if the gap is so narrow that it obstructs the passage of the above-mentioned deposits, or if the dam wall and the rotating side wall are in sliding contact, the short glass fibers are originally removed outside the collecting device. However, the aforementioned deposits will be wiped away at the edge of the dam wall when the pivoting side wall is reversed, and the deposits, i.e. droplets or lumps of binder or aggregates of dispersed fibers of glass wool, will The gap could not be narrowed beyond a certain value because the lumps would fall onto the perforated conveyor belt, be collected, and be mixed with the deposited glass wool matte, reducing the quality of the product.

Therefore, in the above-mentioned known apparatus, in order to maintain the quality of the glass wool mat product, it has been accepted that the reduction in the suction efficiency of the suction box due to the gap size of 1 ft is unavoidable.

The present invention improves the quality of both sides of the glass wool mat in the width direction by having the configuration described in the claims, and also improves the efficiency of sucking the dispersed fibers of the glass wool in the glass short fiber collection device. This made it possible to modify it to do so. That is, according to the configuration of the present invention, even if the members corresponding to the dam wall and the rotating side wall in the known device are brought into sliding contact, droplets or lumps of binder or agglomerates of dispersed glass wool The fibers are collected on a perforated conveyor belt and are deposited on a glass wool mat that does not fall or mix with the mat, and is made of high quality glass wool mat with a uniform fiber density and a beautiful surface and even distribution of binder. It can be manufactured with low suction efficiency.

The short glass fiber collecting device according to the present invention has the structure 9 described above, and in order to regulate the width of the glass wool mat collected and deposited on the perforated conveyor belt,
Within the opposing range of the mutually opposing inner surfaces of the hood side walls disposed on both sides of the perforated conveyor belt, the perforated conveyor belt Since there is a cleaning area on the surface of the annular plate that is continuous with the cotton collection area, it is possible to ensure that droplets or lumps of binder or clumps of glass wool dispersed cotton attached to the surface of the annular plate are removed. It is possible to remove these deposits, prevent them from being mixed into the glass wool mat product, and improve the quality of both sides of the collected glass wool mat in the width direction.

In addition, the annular plate forming the side wall of the hood is cleaned of various deposits and then turned over, so that the front dam wall and rear dam located in the front and back direction of the cotton collecting area are Even if it is moved and reversed in close sliding contact with a wall, the various deposits mentioned above will be peeled off at the sliding contact area.
Since there is no risk of falling onto the perforated conveyor belt, the annular plate forming the hood side wall is always placed in close sliding contact with the front and rear dam walls, and the glass wool is removed by a vacuum suction box. It also has the remarkable effect of improving the suction efficiency of dispersed cotton.
