Description

Blank drying device for energy-saving wide kiln

Technical Field

The invention relates to the technical field of kiln equipment, in particular to a blank drying device for an energy-saving wide kiln.

Background

The industrial kiln is key equipment for producing inorganic materials, and is widely applied to high-temperature projects such as raw material calcination, ceramic firing, metal heat treatment and the like. Taking the firing of inorganic non-metallic materials such as ceramics and refractory materials as an example, industrial kilns can be divided into two major types, namely an intermittent kiln and a continuous kiln, according to the operation mode. The production of the batch kiln is carried out intermittently: and (3) putting all the products to be fired into the kiln, closing the kiln door, heating and firing according to a set firing system, keeping the temperature for a certain time, cooling, opening the kiln after the kiln is cooled, taking out the products, and then putting the next batch of products into the kiln for next firing. The advantages of a batch kiln include: the method can be used for firing large-scale products, has large production flexibility, small occupied area and the like, but has the defects of high energy consumption, large temperature difference in the kiln, small yield, easy fluctuation of product quality and the like. The main types are down-draft kilns, bell-jar kilns, shuttle kilns, etc. The down-draft kiln is a traditional kiln type and is mainly used for firing artistic porcelain. The bottom or cover of bell jar kiln can be separated or closed by lifting mode, and can be used to burn large products, but its lifting structure is complex, cost is high, and after the cover and bottom are separated, the external cold air can be quickly fed into the kiln, and can produce thermal impact on the products and kiln chamber, and can affect product quality and kiln service life. The shuttle kiln consists of a kiln chamber and a kiln car, and a product to be burnt is placed on the kiln car and pushed into the kiln chamber for burning.

During the production process of the baked brick, the drying of the green body is an indispensable important part in the whole process flow from the natural airing in the past to the artificial drying popularized in recent years. The quality of the drying effect influences the productivity of the roasting kiln to a great extent, and various performance indexes of the product and the like. In the drying process of the green body, the green body still needs to be subjected to a heating stage, a constant-speed drying stage and a speed-reducing drying stage. The drying process is a process of heat and moisture exchange between the green body and a drying medium (hot air) in a drying chamber. The heat medium transfers the heat of the heat medium to the green body, takes away the water diffused from the wet green body, and reduces the temperature and increases the humidity of the green body. The gas with higher temperature and lower moisture content is changed into the gas with lower temperature and higher moisture content, and the gas is discharged out of the drying chamber through the moisture discharge system. The temperature of the green body rises after absorbing heat, simultaneously the moisture in the green body is discharged, and the green body with higher temperature, lower moisture content and lighter weight is slowly changed from the green body with low temperature, high humidity and heavier weight. When the existing wide kiln is used, the following problems are mostly existed: (1) the existing kiln production line is mostly formed by combining a plurality of kiln bodies with different functions, and because the weight of the kiln is heavy, when the position of the kiln needs to be adjusted, the kiln is difficult to shift, and the operation is troublesome; (2) when the blank is dried, the temperature in the kiln is required to be controlled according to the dryness and humidity of the blank, and the air outlet in the existing kiln is fixed, so that the height position of the air outlet cannot be adjusted, and the temperature of the kiln blank cannot be well controlled; (3) the embryo body can constantly release out steam and some corrosive gas in the drying process, and this needs in time to discharge steam and corrosive gas when production, and current kiln equipment is lower to the waste heat utilization ratio of waste gas, can not satisfy energy-concerving and environment-protective requirement.
