Feeding sealing and anti-blocking device and method for rotary equipment

Abstract

The invention discloses a rotary equipment feeding sealing and anti-blocking device and method.The rotary equipment feeding sealing and anti-blocking device comprises a material purging pipeline and an ultrasonic sensor, the material purging pipeline comprises a material purging ring pipe, a material purging branch pipe and an electric control valve, the material purging ring pipe is arranged on the vertical section of a kiln entering elephant trunk in a surrounding mode, and the material purging branch pipe is arranged on the vertical section of the kiln entering elephant trunk in a surrounding mode; a plurality of material purging branch pipes are uniformly connected in the circumferential direction of the material purging ring pipe, the lower ends of the material purging branch pipes are obliquely inserted into the root part of the vertical section of the kiln entering articulated chute, and the material purging ring pipe is communicated with air supply equipment through an electric control valve and a connecting pipe; the ultrasonic sensor is arranged at the upper end part of an inclined pipe of the kiln-entering articulated chute; the ultrasonic sensor and the electric control valve are respectively connected with the controller; the air curtain is formed by jetting compressed air, and hot air is prevented from returning upwards from the kiln entering articulated chute; an ultrasonic sensor purging pipeline is arranged, so that the ultrasonic sensor is prevented from being polluted by dust, and the detection accuracy is improved.

Description

Technical field: [0001] The invention relates to a feed sealing technology for rotary equipment, in particular to a feed sealing and anti-blocking device and method for rotary equipment. Background technique: [0002] The kiln entry device of the rotary equipment is generally the kiln entry chute. In order to prevent the hot air from returning upward from the kiln entry chute, a flap valve is usually set to form a material seal to prevent back air. [0003] When dealing with viscous materials, the flap valve is inflexible and cannot function as a seal. There will also be sticky material in the kiln chute. When there is too much sticky material, it will even cause blockage, which will lead to material breakage in the production line, which requires manual feeding, which consumes a lot of manpower and time, and seriously affects the production process. Invention content: [0004] The technical problem to be solved by the present invention is to overcome the deficiencies of ...

Problems solved by technology

[0003] When dealing with viscous materials, the action of the flap valve is not flexible and cannot play the role of sealing

There will also be sticky material in the chute into the kiln. When there is too much sticky material, it will even be blocked, causing the production line to break the material. It needs to manually poke the material, which consumes a lot of manpower and time, and seriously affects the smooth flow of production.
