Design and application of ship conveyor

Composition and typical processing technology of ship loading conveyor: port transportation machinery and equipment mainly includes continuous conveying equipment, port handling machinery and equipment, and auxiliary machinery and equipment. Among them, the key of continuous conveying equipment is belt conveyor; The key of loading and unloading mechanical equipment includes various ship unloaders, ship loaders, car unloaders, car dumpers, stackers and reclaimers, etc; The key of auxiliary machinery and equipment includes storage bin, vibrating feeder, measurement and verification equipment, iron removal equipment, various protective equipment, etc. According to the different main uses of the port, based on the belt conveyor, equipped with different loading, unloading and handling machinery and equipment, a port loading, unloading, handling and transportation system software with very working capacity can be completed. A system software generally has multiple production processes. The typical production processes of port loading, unloading, handling and transportation include the following categories:

1 unloading (ship) -- stacking steps;

2 loading - pre configuration (vehicle) steps;

3 loading ---- transportation steps to the application enterprise;

4 unloading (ship) -- direct cutting steps of loading (ship);

5 unloading (ship) -- direct cutting steps for transportation to the application enterprise;

The overall provisions of the design scheme of the shipping conveyor are as follows:

(1) Clear cutting methods, and clearly put forward the provisions of feeding equipment and dumping equipment;

(2) Clarify the internal relationship between the belt conveyors of the transportation system software. According to the start-up sequence, the belt conveyor receiving material moves first, and the shutdown sequence is that the belt conveyor feeding material breaks first. When the main parameters of the belt conveyor are different, the start-up and shutdown time are required according to this correlation;

(3) When the above start-up and shutdown sequence cannot be reached, consider adding a buffer hopper between belt conveyors to improve the adaptability of the system software and the operation rate of the system software;.

(4) According to environmental protection regulations, for the situation of large smoke and dust, it is necessary to consider the selection of closed transportation or the setting of necessary machinery and equipment such as ash removal and dust removal;

(5) Standardization and integration of parts and components and supply probability of spare parts;

(6) The belt conveyor with the specified inclination angle integrated into the processing technology is adopted. According to the characteristics of raw materials and the natural environment of working conditions, the allowable transportation inclination angle is 15 ° for upward transportation and 10 ° for downward transportation;

(7) The relaxation of the adhesive tape adjacent to the middle of the buffer idler group shall not exceed 1%;

(8) When starting the braking system of the belt conveyor, the supporting force in large operation shall not exceed 1.5 times that in normal operation;

(9) The design scheme of the included angle of the concave arc section of the belt conveyor shall be such that when the belt conveyor is started with full load, the adhesive tape will not get rid of the buffer idler and will not cause the ribbon condition;
