A self-cleaning anti-coking mechanism

Abstract

The invention relates to a self-cleaning coke hang prevention mechanism. The self-cleaning coke hang prevention mechanism comprises a support, a charring cylinder, a shaftless screw, a driving apparatus, a feed inlet tank and a feed outlet tank, wherein the feed inlet tank and the feed outlet tank are mounted on the support; the shaftless screw is transversely arranged in the charring cylinder, one end of the shaftless screw is connected with the driving apparatus, and the other end of the shaftless screw floats in the charring cylinder; the charring cylinder is in rotary sealing connection with the feed inlet tank and the feed outlet tank, and the feed inlet end and the feed outlet end of the charring cylinder respectively extend into the inside of the feed inlet tank and the feed outlet tank. A feed inlet is formed in the upper part of the feed inlet, and a screw conveyor mechanism is arranged below the feed inlet; a fume outlet is formed in the top of the feed outlet tank, and a feed outlet is formed in the bottom; a transmission apparatus is further arranged on the support, and the transmission apparatus drives the charring cylinder to rotate. According to the mechanism provided by the invention, the transmission apparatus drives the charring cylinder to rotate to a certain angle; by means of extrusion and friction with the inner wall of the charring wall in the material pushing process, hanging coke accumulated on the inner wall of the charring cylinder is automatically removed, so that the occurrence of material blocking is prevented, and long-term wear for local area of the charring cylinder is avoided.

Description

Technical field: [0001] The invention relates to the field of material conveying equipment, and more specifically relates to a self-cleaning and anti-coking mechanism. Background technique: [0002] The existing carbonization furnace is usually a spiral propulsion type carbonization furnace. Compared with the traditional shafted spiral, the shaftless spiral adopts a design without a central shaft, and uses a flexible integral steel spiral to push materials, so it has anti-winding properties. Strong, without the outstanding feature of central shaft interference, it can transport materials that cannot or are not easy to be transported by traditional shafted screws, such as granular and powdery materials, wet and pasty materials, semi-fluid and viscous materials, easy to entangle and easy to block materials and so on are being used more and more widely. [0003] Recently, if figure 1 As shown, the spiral propulsion carbonization furnace includes a furnace body 1', a screw con...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-cleaning anti-coking mechanism for the deficiencies of the prior art. The shaftless spiral and the carbonization cylinder rotate relatively, and the shaftless spiral can be effectively removed through the extrusion and friction during the material pushing process. And the coke accumulated on the inner wall of the carbonization cylinder solves the problem of material blockage due to coke hanging in the local area of ​​the inner wall of the carbonization cylinder, realizes continuous production, reduces energy consumption, prolongs the service life of the furnace body, improves production efficiency, and reduces production costs
