Description

one

The invention relates to fiber deposition chambers for directing the flow of glass fibers leaving the diffuser with simultaneous application of synthetic bonding materials and uniform distribution in the mat on the carrier body of the receiving conveyor.

Known camera consists of the shift, the receiving conveyor, the box subgrid space and the exhauster.

The fiber current with the spent energy carrier from the inflation unit enters the shaft and vertically lowers onto the carrier body of the receiving conveyor (grid), evenly distributed across the width of the conveyor under the action of the vacuum created in the box of the subgrid-type smoke exhaust system.

In this case, the rarefaction is evenly distributed over the entire area of the receiving conveyor grid, equal to the lower section of the shaft.

However, at the same time with the fibers, all non-fibrous inclusions formed during the infusion of the melt and not entering the fluid in the energy carrier stream simultaneously with the fiber, are formed into the thickness of the fiberglass carpet formed on the grid of the conveyor. The presence of non-fibrous inclusions in finished products reduces their quality.

The purpose of the invention is to improve the quality of the fiber.

For this, the subgrid box space is divided by a partition into a zone of collection of non-fibrous inclusions and a zone of fiber deposition.

The drawing shows the proposed fiber deposition chamber, a longitudinal section.

The proposed fiber deposition chamber consists of a shaft 1 for directing a stream of elementary glass fibers leaving the diffuser to the grid 2 of the receiving conveyor, on which a glass fiber carpet is molded. Under the upper branch of the grid, there is a duct 3 of netting space, which is used to evenly determine the rarefaction on the width of the grid. In the subgrid area, the camera 5 for trapping non-fiber inclusions is installed vertically under the diffuser 4.

The fiber deposition chamber is installed on the production line but for the production of thermal insulation from staple fiberglass under the blowing section 6.

Formed in node 6 of the blown-up notes of energy carrier, glass fiber and non-fibrous inclusions, entering through the diffuser 4 into the shaft 1, is directed vertically down onto the grid 2 of the receiving conveyor.

Since the grid section under which the vacuum has been created is displaced from the vertical axis of the inflation unit in the direction of movement of the working branch of the conveyor, the energy carrier and the fiber deviate from the vertical direction towards this section. The energy carrier passes through the grid into the grid box 3, from where the smoke exhauster is emitted into the atmosphere, and the fiber sits on the grid, forming into a fiberglass carpet 7, transported by the receiving conveyor further along the technological process. However, non-fibrous inclusions, having a large inertia, move but vertically and wake up through a bare mesh into the chamber 5 of trap of peat-fiber inclusions. Thus occurring
