Perlite production equipment

Abstract

Perlite production equipment mainly comprises a raw material pit, an elevator, a rotary drying kiln, an expansion furnace, a dust remover, an induced draft fan, an air volume regulating valve, a settling chamber, a finished product bin, a cyclone material collector, an air blower and a communication air pipe. The lower end of the elevator is positioned in the raw material pit, the upper end of the elevator is connected with the rotary drying kiln, a discharge outlet of the rotary drying kiln is connected with a feed inlet of the expansion finance, the rotary drying kiln is communicated with the dust remover by a pipeline, the dust remover is connected with the induced draft fan by an air pipe and communicated with the expansion furnace via the air volume regulating valve, the expansion valve is communicated with the settling chamber, the settling chamber is communicated with the cyclone material collector, one side of the cyclone material collector is communicated with the finished product bin by an air pipe while the other side of the cyclone material collector is communicated with the air blower, the cyclone material collector is further communicated with the rotary drying kiln by an air pipe, and an integral system is in a closed-loop control state. The perlite production equipment is fast in temperature rise and easy in temperature control, ignition loss of a furnace body is little, the service life of the perlite production equipment is prolonged, expansion efficiency is improved, energy consumption is low, utilization rate is high, repair workload is low, automatic control is realized, labor is saved, an operating environment is enhanced, and emission of greenhouse gases is reduced.

Description

technical field [0001] The invention relates to the technical field of building material production industry and energy saving and environmental protection, in particular to an energy-saving and environment-friendly perlite production equipment. Background technique [0002] Perlite is an inorganic thermal insulation material, which has been widely used in metallurgy and building materials industries. The equipment for producing perlite has developed from coal-fired rotary drying kilns and coal-fired extruders to rotary drying with gas and electricity as heat sources. Kiln and puffing electric furnace. Grading recycling technology has been promoted and applied. However, the recovery and utilization of waste heat is still in the development stage, and a large amount of high-temperature flue gas is directly discharged into the atmosphere, causing energy waste and environmental pollution. Contents of the invention [0003] The purpose of the present invention is to provide ...
