Vertical type gradient continuous sintering machine

Abstract

The invention belongs to the technical field of sintering ceramsite products and discloses a vertical type gradient continuous sintering machine which comprises a furnace body, an inner core tube, a feeding cabin, a plurality of combustion chambers, a discharging assembly and an external air distribution hole, wherein the inner core tube is arranged in the middle of the furnace body; a sintering cavity is formed between the furnace body and the inner core tube; the top of the inner core tube is open, and the bottom of the inner core tube communicates with a negative pressure air draft assembly; an internal air distribution hole is formed in the side wall of the inner core tube; the feeding cabin is arranged at the top of the furnace body; discharging holes of the feeding cabin are correspondingly formed between the furnace body and the inner core tube; a flow guiding air flue is arranged between the top of the inner core tube and the bottom of the feeding cabin; the combustion chambers are uniformly formed in the outer side of the furnace body in the circumferential direction; and combustion ports corresponding to the combustion chambers are formed in the furnace body. The vertical type gradient continuous sintering machine is novel in structural design and steady and reliable in operation, sinters under negative pressure and is small in energy consumption and high in yield. The breakage ratio of finished aggregate is low; and the product is excellent in particle shape, large in bulk density and low in powder passing rate.

Description

technical field [0001] The invention belongs to the technical field of ceramsite product sintering, and in particular relates to a vertical gradient continuous sintering machine. Background technique [0002] Gradient continuous sintering machine is a product equipment specially developed and designed by the applicant for industries such as environmental protection, industrial solid waste, mining, metallurgy, building materials, refractory materials, ceramics, and chemicals. Its unique sintering principle makes the sintering material particle size damage rate low, the output large, and avoids the generation of high-pollution smoke and dust, effectively solving the problems of high energy consumption, high production cost, and high sintering material damage rate of the rotary kiln. And the gradient continuous sintering equipment is suitable for bulk industrial solid waste treatment, raw ore desulfurization, aggregate drying, fly ash ceramsite, tailings ceramsite, and urban sl...
