A kind of high temperature resistant air lock

Abstract

The invention provides a high-temperature-resistance air seal machine. The high-temperature-resistance air seal machine comprises a shell, a feeding opening and a discharging opening are designed in the upper face and the lower face of the shell correspondingly, a horizontal transmission shaft is assembled inside the shell, and an impeller is assembled on the transmission shaft; side walls are installed on the left face and the right face of the shell correspondingly, the transmission shaft is installed at the middle positions of the left side wall and the right side wall in a rotatable and sealed manner, and the left end and the right end of the transmission shaft extend out of the side walls correspondingly; an annular side interlayer is designed at the middle positions of the side walls; shell interlayers with the arc cross sections are designed on the front wall and the back wall of the shell correspondingly; and a horizontal shaft hole is machined in the middle of the transmission shaft. By means of the air seal machine, cooling water can be used for rapidly and efficiently decreasing temperature, and therefore high-temperature materials can be transported.

Description

technical field [0001] The invention relates to the technical field of fan shutoff equipment, in particular to a high temperature resistant fan shutoff device. Background technique [0002] The air shutoff device, also known as the unloading valve, is the main equipment for dust removal, air supply and other equipment feeding for dust removal equipment. It is suitable for powdery and granular materials. The unloading valve can be used in the pneumatic output system, which can block the air pressure of the upper and lower parts of the unloading valve and play the role of air lock; at the same time, it can supply the material to the delivery pipe uniformly and continuously. It can also be used to evenly feed granular materials. According to the air temperature and pressure it can withstand, it is divided into three categories: ordinary type, pressure resistant type and high temperature resistant type. The traditional high temperature-resistant air lock can only be used at a ...

AI Technical Summary

Problems solved by technology

The traditional high temperature-resistant air lock can only be used at a high temperature of a few hundred degrees, and cannot be used in some situations that require high temperature conditions of thousands of degrees

In addition, traditional high-temperature-resistant air locks usually increase the distance between the transmission motor and the housing to achieve high-temperature work, which increases the volume of the air lock and makes it difficult to transport and assemble. The heat generated in the housing is discharged directly into the outside space, resulting in excessively high temperatures in the production area

When the air lock is running, the blades of the traditional air lock are easy to jam with the opening of the air lock; and the inside of the air lock is often used to transport some materials that are easy to adhere, and these materials will also adhere to the blades of the air lock The edge, causing the blade and the opening of the air locker to jam

The transmission structure of the air lock often uses a sprocket structure. At this time, the chain will exert a torsional force on the input shaft assembled at the end of the air lock. During long-term use, it is easy to cause rapid wear of the transmission bearing, the input shaft and the input shaft. The twisting and deformation of the impeller on the shaft relative to the installation shell will further cause contact friction and jamming of the impeller during operation
