Description

a warehouse system

technical field

The utility model belongs to the technical field of coal bunker clearing and blocking, in particular to a bunker system, which is especially suitable for vertical coal bunkers such as mine underground coal yards, gangue silos, and above-well coal yards.

Background technique

The storage and throughput of coal bunker is an important link in the production process of coal mine, and it is an indispensable key part in the production and transportation of coal mine, and it plays a decisive role in the production capacity of coal mine. Especially with the continuous improvement of the mechanization degree of underground fully mechanized mining and the continuous increase of coal loading and transportation capacity of coal washing plants, the capacity of coal bunker is gradually increasing, and the use efficiency is getting higher and higher. However, in the production and use process of almost all coal bunkers in mines, there are bunker blocking problems to varying degrees, which need to be dealt with frequently. This not only fails to give full play to the due role of the coal bunker, but also seriously affects normal production, especially in deep coal mines. The clogging problem of coal bunker is particularly prominent. The blockage of the coal bunker seriously affects the normal production of the mine, and accidents are prone to occur during processing. The blockage of the coal bunker has become a common problem in coal mining enterprises at home and abroad. Then, the raw coal transportation cannot be carried out for a few days, which seriously affects the production efficiency, and even causes production stoppage, causing huge economic losses to the enterprise. The treatment of coal bunker blockage in mines is one of the research hotspots in the field of blockage removal technology at home and abroad, and it has extremely important practical significance for the continuous stable and high production of coal mines.

At present, the commonly used methods to deal with the problem of coal bunker blockage are artificial arch breaking method, blasting vibration method, air gun arch breaking method, curve structure design method, etc., but these methods have the following defects in the use process: ① Manual arch breaking method, generally In this case, several holes are reserved on the inclined wall of the coal discharge port of the coal bunker. Once the coal bunker is arched, use a tool to insert it into the bunker and stab it or manually beat it with a sledgehammer. The method is simple in design and low in cost, but the labor intensity of workers is high, and it will lose its effect when the warehouse is severely blocked. ② For the blockage with a higher distance from the lower port, the blasting vibration method is often used. Before blasting, the gas inspection must be carried out according to the requirements of safety regulations. The amount of explosives per blasting should not exceed 450g. The disadvantage of this method is that the safety is poor, and the preparation time It is long, and sometimes the collapse of the funnel or the destruction of the warehouse body occurs, so there are many unsafe factors. ③The air cannon arch breaking method is the most commonly used method at present. An air cannon arch breaking device is installed at the bottom of the coal bunker. The air flow generated by the sudden release of the compressed air causes impact and vibration on the material, so that the material loosely falls, although it reduces the labor of workers. For some serious silo blocking accidents, the effect of this method is not very obvious, and the lump coal rate is reduced.

In order to solve the above problems, a domestic utility model has developed a coal bunker anti-blocking and clearing system and method to improve the coal bunker blocking accident. The silo, the middle silo and the lower silo, the upper silo has a feeding port, the lower silo has a discharge port, the middle silo is in the shape of a conical cylinder with a large upper and a small lower, and the upper and lower ends of the silo are respectively connected to the upper and lower ends. The lower end of the silo and the upper end of the lower silo are rotatably connected, the middle silo is provided with a first block clearing piece that is fixed relative to the upper silo and the lower silo, and the first clearing piece is close to the middle silo. On the side wall, the coal bunker anti-blocking and clearing system is also provided with a first drive device for driving the middle silo to rotate around the axis of the middle silo and an air cannon for providing compressed air in the upper silo, but the utility model still adopts The principle of the compressed air gun has not changed much in essence. In addition, a new anti-blocking raw coal bunker has been developed in China, which is composed of a straight cylinder section, a round table section, an eccentric round table section, and a movable section. The straight barrel section is connected with a round table section and an eccentric round table section in turn. The eccentric round table section is: Asymmetric structure, the eccentric circular table section and the movable section are connected by a hoisting chain, and a vibration motor is installed on the outer wall of the movable section, which relies on the vibration motor to generate vibration to promote the silo to pass through. However, the vibration device used in this aspect is not only noisy. , but also affects the lump coal rate of coal, and is not suitable for underground use. Therefore, how to solve the problem of coal bunker blockage in coal mines has become a major problem to be solved urgently by engineers and technicians.

In short, the coal bunker technology used in the past is unreasonable in terms of design ideas and practical issues, and it is urgent to develop a new type of safe silo system.
