Technical Field

A molecular sieve filling system belongs to the technical field of hollow glass manufacturing equipment.

Background

The hollow glass mainly comprises glass, spacing strips, a molecular sieve and sealant. The molecular sieve can adsorb water and residual organic matters in the hollow glass, so that the hollow glass still keeps smooth and transparent even at a very low temperature, and the performance of the hollow glass is determined by whether the molecular sieve can safely and reliably finish filling, so that the molecular sieve filling process is particularly important.

The filling of molecular sieve is accomplished by special molecular sieve filling equipment in cavity glass production process at present, and filling equipment structure principle is mostly the same on the market, and main operating principle utilizes vacuum apparatus to inhale the material through the pipeline from bottom storage silo and send to upper portion storage silo, and the rethread lets in compressed air in the storage silo of upper portion and makes the inside pressure boost of storage silo of upper portion, and the molecular sieve flows into the prefabricated filling hole of space bar, accomplishes the filling.

The filling process has a plurality of problems, the molecular sieves have high running speed under the action of vacuum and compressed air in the filling process, friction and collision are very easy to occur between the molecular sieves and the inner wall of the filling device under the action of air flow, especially under the action of rotating air flow in the filling device, the crushing rate and dust of the molecular sieves are increased, powder is very easy to emit during filling, and if the molecular sieve fragments and dust are filled into the spacing strips, the inner cavities of the hollow glass are easily polluted, the transparency is influenced, and the defective products of the products are increased due to the fact that the molecular sieves cannot be cleaned. The molecular sieve mainly acts to adsorb water in the inner cavity space of the hollow glass, does not form water mist, and prolongs the service life of the hollow glass. The adsorption rate is an important index of the molecular sieve, and if the molecular sieve is frequently contacted with air in the filling process, the adsorption rate can be continuously reduced, so that the service life of the hollow glass is influenced. At present, a feeding system of molecular sieve filling equipment is divided into two sections, wherein one section is used for feeding materials from a bottom storage bin to an upper storage bin by using a vacuum pump, the other section is used for filling materials in the upper storage bin into spacing bars through compressed air, each section of feeding materials can be carried out only through rapid exchange with external air, the molecular sieve adsorption capacity is greatly reduced through rapid ventilation, and hollow glass failure is caused.
