SU1256803A1 - Apparatus for defluffing and delivering mixture on base of fibrous material - Google Patents

Description

The invention relates to devices for grinding materials and can be used for spraying and feeding a mixture based on fibrous material when applying insulating coatings to metal HTBjibHbie structures, pipelines and heat units.

The purpose of the invention is to improve the quality of fluff and the uniformity of the flow of the mixture of fluff material.

FIG. 1 shows a device for setting and feeding the mixture to the bases of a fibrous material; in fig. 2 shows section A-A in FIG. one; FIG. 3 is a section B-B in FIG. 1; in fig. 4 shows a section B-B in FIG. one,

The device contains a hopper 2 mounted in a common housing with drive rippers 3 and 4 and a screw 5. Coaxially with a screw 5, the gun is mounted 6 in the form of a drive drum with a finger-operated tool, communicated with the hopper 2 by the end part. Under the fuse box 6 there are successively located a drive cell feeder-gate 7 and a discharge pipe 8 connected to the air supply line 9. The discharge pipe 8 is located at an angle to the forming cell feeder 7, made in the form of a shaft with radially located blades 10 and seals P at the periphery of the blades 10. In the upper part of the hopper 2, a grid 12 is installed. The rippers 3 and 4, the screw 5, and the gate feeder 7. are driven by a motor 13 with a gearbox 14. there is from engine speed 15. The discharge pipe 8 has a safety valve 16

The device works as follows.

The fibrous material is poured into the hopper 2 through the grid 12 and enters the rippers 3 and 4, which loosen it with their fingers. Screw 5 delivers the loosened fiber; the material is fed into the fluff 6, where the fibrous material is melted. From the gun 6, the material enters the sectors of the cell feeder - gate 7 and then falls into the air flow 5 coming into the discharge pipe 8 from the line 9. Formed by an air-fibrous mixture is sent from the discharge pipe to the consumer. The screw supply of the device and its coaxial arrangement with the puppet; and also their separate drive allows the metered and adjustable supply of prelonged fibrous material to the puffener, which increases the quality of the fluff and the uniformity of the material feed.

The location of the discharge pipe at an angle to the generator of the cell-gate feeder reduces the pulsation of the material supply by sucking fibrous material into the discharge port from adjacent sets of the cell-gate gate, The optimum angle "and the position of the discharge tube relative to the generator cell feeder is determined from the following relationship

An air pressure limitation in the cell feeder-gate is provided by the safety valve M 16.
