Bulk material storage yard automatic warehouse discharge system

Abstract

The invention discloses a bulk material storage yard automatic warehouse discharge system. A bulk material falls underground through an electric arc door, is fed to a ground cage belt by a vibration feeder, and is conveyed out of a yard by the ground cage belt; the system circularly and repeatedly monitors the height of a material stack through a material meter mounted and hung above a bulk material stack; the real-time stock conditions of the whole bulk material storage yard are judged through the height of the material stack; through the real-time stock conditions of the bulk material storage yard, the system automatically dispatches the proper material stack for delivery according to the warehouse discharge purpose; the corresponding arc door and the feeder are opened; the system is further provided with a belt weighing metering device at the tail end of the ground cage belt in bulk material delivery for measuring the accumulated passing weight of the bulk materials on the belt in real time; the real-time weight is compared with a target loading quantity of transportation vehicles and ships; if the real-time weight is lower than the target loading quantity, the delivery conveying process is continued; if the real-time weight reaches the target loading quantity, the system immediately closes the arc door, and stops the feeder; and after the instant metering of the belt is zero, the belt is closed, and the delivery process is finished.

Description

technical field [0001] The invention belongs to the technical field of logistics equipment, and in particular relates to an automatic warehouse-out system for bulk material yards. Background technique [0002] Materials that exist in granular form, including coal, ore raw materials, sand aggregates, grain, etc., are collectively referred to as bulk materials, also referred to as bulk materials for short. Bulk materials are the same as other industrial and agricultural products, and the production sites, secondary processing sites, and use sites are often far apart in distance, so long-distance transportation is required. Long-distance transportation requires a place to store bulk materials, and the storage place for such bulk materials is the bulk material yard. Bulk materials will not be packaged in the yard, and will be stacked in the storage area of ​​the yard in a natural stacking situation. [0003] In the traditional bulk material storage yard, the bulk material is u...

Problems solved by technology

[0006] The main problems of this traditional delivery method are: 1. The storage area of ​​the bulk material yard is huge, and it is completely impossible to visually observe which piles of bulk materials that need to be delivered are full and which piles are full. Less or even none. The usual method of operation is to simultaneously open multiple arc doors and corresponding feeders in the target bulk material delivery area, and control the material discharge under a blind operation. For example, the bulk material pile has been fully discharged It cannot be discovered in time, and we can only passively wait for the feedback information of the loading and loading positions before making adjustments.

This mode of operation is inefficient and wastes power consumption

2. There is no real-time measurement of the outbound volume. According to the loading and loading position, the operator observes whether the vehicle and ship are full, or observes the draft. After the target loading weight is expected to be reached, the operator of the bulk material yard is notified to close the arc door and feed the material. machine, cage belt

This method of operation will cause the actual loading volume to always be inconsistent with the target loading volume, and the gap is likely to be large, resulting in the need for secondary operations such as reloading, which consumes a lot of time and manpower

At the same time, the amount of loading is controlled by the operators at the loading and shipping positions, which may easily lead to incidents of stealing and selling bulk materials
