Description

Sintering machine bellows system Technical Field The utility model relates to the technical field of sintering machine equipment, in particular to a sintering machine bellows system. Background Sintering production is carried out from top to bottom by means of air draft and negative pressure, and is a continuous melting and consolidation physicochemical reaction process, obvious five layers exist in the longitudinal direction, and the air permeability of each layer is inconsistent. The lower part of the sintering machine is provided with an air box, and the air box is used for sucking air into the sintering material layer by utilizing negative pressure formed by the fan, so that solid fuel in the material layer is continuously combusted to provide heat for sintering ore. In order to ensure that the sintering production is stably carried out, the sintering process is required to be balanced and consistent along the width direction of the sintering trolley, so that the method can exert the optimal performance and obtain better production quality indexes. Otherwise, the sintering process is affected, so that not only is the sintering parameters unbalanced, but also the quality index is affected. If the bulletin number is CN216245554U, a sintering machine bellows and an exhaust system device are disclosed in 2022, 04 and 08, and the sintering machine bellows and the exhaust system device belong to the technical field of sintering. The technical scheme includes that the sintering machine air box and air draft system device comprises a sintering air box, an air box butterfly valve, an air box inclined tube, an air box branch tube and an air draft flue, wherein the sintering air boxes are symmetrically arranged left and right, a partition plate is arranged between the left sintering air box and the right sintering air box, the lower parts of the air boxes on the two sides are respectively provided with the air box butterfly valve capable of being independently controlled, an air outlet of the left sintering air box is connected with the air box inclined tube, the lower part of the air box inclined tube is connected with the air box branch tube through a square round joint, and the lower end of the air box branch tube is inserted into the left air draft flue. When the sintering machine bellows disclosed by the above is used, the elbow on the bellows inclined tube is easy to damage due to the impact of smoke, and the practicality is poor. Disclosure of Invention The utility model aims to provide a sintering machine bellows system with longer service life. According to the utility model, the strength of the elbow is increased through the reinforcing structure and the wear-resistant layer arranged on the elbow, so that the service life of the elbow is prolonged, the service life of the whole bellows system is prolonged, and the practicability is higher. In order to achieve the purpose, the technical scheme adopted by the utility model for solving the technical problem is that the sintering machine bellows system comprises an elbow arranged between a sintering bellows and a flue, wherein a reinforcing structure is arranged on the elbow, and a wear-resistant layer is arranged on the inner wall of the elbow. The wear-resistant layer is a ceramic layer. A flap valve, a square-square round and an expansion joint are arranged between the sintering bellows and the elbow, and the elbow is communicated with the flue through a vertical pipe. And a reinforcing grid is arranged on the inner wall of the flap valve. Reinforcing rib plates are arranged on the heaven and earth circles. The inner wall of the square-earth circle is provided with a ceramic lining. And a wear-resistant honeycomb duct is arranged in the expansion joint. And a ceramic reinforcing layer is arranged on the vertical pipe. And the flue is provided with an ash collecting hopper. The beneficial effects of the utility model are as follows: Flue gas enters the flue through the bellows and the elbow of the sintering machine, the wear resistance of the elbow is increased through the reinforcing structure arranged on the elbow, and the wear resistance of the inner wall of the elbow is increased through the wear-resistant layer on the inner wall of the elbow, so that the service life of the elbow is longer, the service life of the whole bellows system is further prolonged, and the practicability is higher; the strength of flap valve is increased through the setting up of reinforcing grid, and the setting up of deep floor slows down the material speed and the impact that bellows got off, increases the life of world circle, protects the expansion joint through wear-resisting honeycomb duct to increase the life of expansion joint, increase the intensity of standpipe through ceramic enhancement layer, and then increase the life of whole bellows system.
