Low-nitrogen gas intake control device for production of cement rotary kiln

Abstract

The invention relates to the technical field of the production of cement rotary kilns, and in particular, discloses a low-nitrogen gas intake control device for the production of a cement rotary kiln.Aiming at the problems that a low-nitrogen gas intake control device for the production of the cement rotary kiln is inconvenient in accurate control of the flow of a nitrogen gas and is not timely in continuation of the nitrogen gas in the prior art, the following scheme is now provided. The device comprises a placement cabinet and two nitrogen gas cylinders, wherein an opening is formed in thefront face of the placement cabinet; a cabinet door is connected to one side of the opening in a hinging manner; two placement plates are connected to the inner wall of the bottom of the placement cabinet in a sliding manner; placement holes are formed in both the tops of the two placement plates; telescopic devices are mounted on both the inner walls of the two sides of the placement cabinet; andracks are connected to extending ends of the two telescopic devices in the hinging manner by connecting mechanisms. The device is reasonable in structure and simple to operate, can be used for quiteconveniently controlling the flow of the nitrogen gas, moreover, cannot affect the normal operation of the production when the nitrogen gas is replaced, and is easy to popularize and use.

Description

technical field [0001] The invention relates to the field of cement rotary kiln production, in particular to a low nitrogen intake control device for cement rotary kiln production. Background technique [0002] Nitrogen is an inert gas, often used as a protective gas in production and life. In the prior art, when the cement rotary kiln is used to produce products, nitrogen gas is often introduced into the cement rotary kiln, thereby reducing the oxygen content in the cement rotary kiln and avoiding the oxidation of the product. [0003] At present, when introducing nitrogen into the interior of the cement rotary kiln, the common way is to pass the nitrogen in the intermediate skill nitrogen cylinder into the interior of the cement rotary kiln. Although this method is simple, there are many problems. Defects, on the one hand, it is inconvenient to precisely control the flow of nitrogen gas, on the other hand, when the nitrogen gas in the nitrogen gas bottle is used up, it is...
