SU41893A1 - Installation for molding refractories compressed air - Google Patents

Description

Compressed air has been proposed for forming concrete masses with a moisture content of about 8-10%.

The present invention refers to the molding by means of compressed air of refractories of both chamotte and dinas refractories from a mixture of low humidity, the dry charge from the bins being transferred through pipes into a mixing chamber, to which a belt press is attached, supplying a wetter binder (clay or lime). For the continuity of the installation, for each dry batch ingredient, two bins are provided for alternately filling and emptying.

In the schematic drawing of FIG. 1 shows a front view of the proposed plant with a partial section; and FIG. 2 - the same, side view.

The proposed installation consists of six feed hoppers 1, six bunkers 5, six feeding hoppers 8 leaving the feed opening into the compressed air flow, the gas pipeline No mixing chamber 17 with a nozzle at the end.

The unit is designed for continuous operation with a capacity of 1 kg

mass per second, composed of three fractions of chamotte or quartz and one fraction of the binding component, either in the form of a soft ribbon of clay, or a slip, or crushed lime, molasses, etc.

The installation starts with the loading of funnel 1,

Capacity of a funnel and the corresponding bunker are calculated on work within 15 minutes; thus, there are always three bunkers in operation, and the rest are on load.

Each bunker has two valves 3 and 7, of which the first one is spring. During operation, the valve 3 is closed, and the valve 7 is open, respectively, with the desired flow of material into the mixing chamber. Each bunker is provided with an air duct 9 through which compressed air is supplied to the bunker. Compressed air coming from the compressor through the pipe 11 enters through the pipe 9 into the bunker, and through the pipe 10 passing under the feed funnel 8, capturing the flowing material, into the mixing chamber 17.

When the loaded hopper is switched on for spraying, the valve 12 opens, air enters the bunker, after

Kerrv with receiving and feeding funnels, piping and mixing chamber with a nozzle is different in that for suzsyh shreds there are bins 5 with bottom valve 7 and top spring valve 3, and for a wetter binder - a belt press 14, directly to the mixing press camera 17.
