Sintering machine bellows control valve and sintering bellows

Abstract

The invention provides a sintering machine air bellow control valve and a sintering air bellow. The sintering machine air bellow control valve can improve the effective availability of the air amount.The sintering air bellow provides technical conditions for increasing the yield of sintered ore. The sintering machine air bellow control valve comprises a valve body, a rotating mechanism and an executing mechanism. The output end of the executing mechanism is connected with the valve body through the rotating mechanism. The valve body is provided with a ventilation opening and a containing cavity, and supporting mechanisms are arranged at the upper end and the lower end of the containing cavity. The sintering air bellow comprises an air bellow straight pipe, a first air bellow branch pipe,a second air bellow branch pipe and the sintering machine air bellow control valve. The first air bellow branch pipe and the second air bellow branch pipe are symmetrically arranged at the two sides of the air bellow straight pipe and are both provided with air openings and air flues. The air bellow straight pipe penetrates through the valve body and is further fixedly connected with a sintering flue. The air bellow straight pipe is provided with two side air openings and a normally-open air opening which is through in the axial direction.

Description

technical field [0001] The invention relates to a sintering machine bellows control valve and a sintering bellows, belonging to the technical field of ironmaking and sintering production in the metallurgical industry. Background technique [0002] In the sintering production process, the greater the air volume passing through the material layer, the faster the sintering speed. The vertical sintering speed in the material layer and the output and quality of the sintering machine are approximately in a positive relationship with the air volume passing through the material layer. Within a certain range, the output and quality of sinter will be improved with the increase of air volume. [0003] The bellows of the sintering machine is one of the important equipments for sintering production. It plays a role in guiding the ventilation of the material layer during the sintering production. The structure design of the bellows has different effects on different sintering machines. T...

Problems solved by technology

As shown in the figure, the bellows and sintering large flue in the existing structure are connected in a 90°T shape. The disadvantage is that the local resistance of the bellows is very large, and the energy efficiency utilization rate is low. After the bellows structure design and installation are completed, each bellows and The local resistance of the branch pipe cannot be changed, and the air volume is a relative fixed value, which cannot be adjusted according to production needs, which seriously restricts the development of sintering technology
