Abstract

The utility model relates to a high-efficiency tunnel kiln which comprises a sintering kiln and a drying chamber communicated with the sintering kiln by a hot air pumping duct, and is characterized in that the sintering kiln with a kiln body inside diameter of 3.6 m to 4.6 m comprises a reinforced concrete base, a kiln top, a kiln body, air channels and a kiln door, wherein the micro-arc kiln top comprises top plates, brick bodies and a heat-insulating cavity arranged between the top plates and the brick bodies, a sintering belt brick body of the kiln body comprises a masonry layer, a heat-insulating layer and an arc-protecting layer, and either preheating belt brick body or cooling belt brick body of the kiln body comprises another masonry layer and another arc-protecting layer; the masonry air channels are respectively arranged at both sides of the kiln body of the reinforced concrete base, a sand seal trough is arranged at the inner side of the kiln body, an examining trough is bricked at the lower part of the inner side of the kiln body, and the kiln door is mounted at the inlet end of the kiln body. Due to the adoption of the micro-arc kiln top, i.e., the kiln body inside diameter of the sintering kiln is from 3.6 m to 4.6 m, the utility model greatly improves the yield and has better thermal performance, low heat consumption and lower cost, simple structure, low manufacture cost and favorable popularization.

Description

A kind of efficient tunnel cave

Technical field

The utility model relates to a kind of efficient tunnel cave.

Technical background

The heavy clay industry tunnel cave of China is used and is had history decades, develop into the flat-top tunnel cave of big or middle section from semicircle vault, three-core vault tunnel cave, output is increased, but so far because the kiln body internal diameter of dome-type tunnel cave only limits to 2.5M～3.6M, so output can't improve again.

The utility model content

The purpose of this utility model is at existing problem, provides a kind of differential of the arc type kiln top to people, and promptly the kiln body internal diameter of calcining kiln is 3.6M～4.6M, and thermal property is better, the output height, and hear rate is low, and kiln structure is simple, the efficient tunnel cave that cost is low.

The utility model comprises calcining kiln and by taking out the hothouse that warm-air pipe is communicated with calcining kiln, it is characterized in that: kiln body internal diameter is that the calcining kiln of 3.6M～4.6M comprises reinforced concrete base, the kiln top, the kiln body, ventilating duct, and wicket, differential of the arc type kiln top is by top board, the roasting band masonry of kiln body is by the brick layer of building of following refractory arch, middle thermal insulation layer and top employing standard brick or coal gangue sintering porous brick, the arch layer that protects that hollow brick is built by laying bricks or stones constitutes, the preheating zone of kiln body, the salband masonry is by brick layer and top employing standard brick or the coal gangue sintering porous brick built of following refractory arch, the arch layer that protects that hollow brick is built by laying bricks or stones constitutes, place the kiln body both sides on the reinforced concrete base to be respectively equipped with brick ventilating duct, kiln body inboard is provided with the sand seal groove, kiln body lower inside is built the maintenance groove, and kiln body entrance point is equipped with wicket.

The masonry both sides are cast with the reinforced concrete longeron and are cast with the equidistant reinforced concrete vertical beam of a row, and reinforced concrete vertical beam lower end is connected with the kiln reinforced concrete base, and the upper end adopts the banded column lacing wire to connect.

Be provided with temperature tube in the calcining kiln, the front portion is the preheating zone in the calcining kiln, and the middle part is the roasting band, and the rear portion is a salband, has coal feeding hole on the kiln top of calcining kiln roasting band, and kiln body entrance point, preheating zone, salband both sides are equipped with the sand tube that adds of logical inboard from top to bottom respectively.

Effect of the present utility model

1, the utility model is owing to adopted differential of the arc type kiln top, and promptly therefore the kiln body internal diameter 3.6M～4.6M of calcining kiln improves output widely, and thermal property is better, and hear rate is low, and cost reduces.

2, the utility model kiln structure is simple, and cost is low, is beneficial to popularization.
