Shifting rod type sorting system and sorting method

Abstract

The invention provides a shifting rod type sorting system and a sorting method. The shifting rod type sorting system comprises a conveyor (1), a recognition system (2) and an execution system (3); materials advance on the conveyor (1); the recognition system (2) recognizes the materials, and coal and gangue are recognized and distinguished; and the gangue is pulled out through the execution system (3). According to the shifting rod type sorting system and the sorting method, the sorting efficiency is high, the sorting particle size range is wide, a sorting system structure is simple, the sorting system cost is low, the sorting system structure is compact, the occupied area is small, flying dust generated in the sorting process is little, and generally, a totally-closed protective cover, an air suction pipeline system, dust removal equipment and the like do not need to be additionally arranged.

Description

technical field [0001] The invention belongs to the technical field of mechanical material sorting, and relates to a lever-type sorting system and a sorting method, which are applicable to material sorting production. Background technique [0002] At this stage, the dry separation methods of coal gangue are as follows. [0003] 1. Manual gangue selection: use a low-speed belt conveyor to transport raw materials. Workers on both sides of the belt conveyor distinguish coal and gangue with the naked eye according to personal experience, and use auxiliary tools such as hooks to hook the gangue to a position that can be reached by the arm, and then use The gangue is taken out by hand and piled up. Disadvantages of manual gangue selection: 1. The efficiency is extremely low: the conveying speed of the general belt is lower than 0.5m / s; 2. It consumes a lot of manpower: to ensure a certain sorting efficiency, enough workers need to be distributed on both sides of the belt. Manual...

AI Technical Summary

Problems solved by technology

Disadvantages of manual gangue selection: 1. The efficiency is extremely low: the conveying speed of the general belt is lower than 0.5m / s; 2. It consumes a lot of manpower: to ensure a certain sorting efficiency, enough workers need to be distributed on both sides of the belt. Manual operation; 3. The range of sorting particle size is small: limited by the physical fitness of the workers, the weight of gangue picked out each time is generally within 50kg, and the gangue with a larger weight cannot be taken out manually; 4. Low sorting accuracy: according to human To distinguish coal and gangue with the naked eye, limited by experience, the error is particularly large; 5. Low safety: manual handling of gangue is easy to be injured

Disadvantages of manipulator picking: 1. The action is relatively complicated: generally, a series of actions such as X, Y, and Z translation, Z axis rotation, claw closing, and opening are required to realize the requirements, that is, generally 6 actions are required ;2. High installation precision requirements; multi-axis linkage, particularly high precision requirements; 3. High configuration requirements and high cost: completing many actions within a limited time requires high configuration including drives, actuators, and control systems, and high costs ; High operation and maintenance costs; 5. Generally used in occasions with large particle size, such as 100-300mm is a relatively reasonable sorting range

Disadvantages of pneumatic jet dry separator: 1. Small particle size separation: generally only suitable for materials within 30-150mm; 2. Lots of auxiliary equipment and high cost: the blowing process will cause dust such as coal dust to cover the entire space, requiring Add fully enclosed shield, air suction piping system, dust removal equipment, etc.

[0006] The above three kinds of dry separation equipment have different defects. They are often affected by external human factors or complex equipment structure, complex maintenance and too many auxiliary equipment, resulting in low sorting efficiency and limited sorting range.
