Problems solved by technology

[0006] None of the technical solutions disclosed in the above invention patents can seal the top of the silo, and the high temperature area in the center of the silo cannot be controlled, so there are the following problems:
[0007] 1. If the top of the silo is not sealed, it will form a chimney-like state of the silo, the oxygen content, methane, etc. cannot be controlled, and the inert gas will lose its effect. Once the top of the silo and the discharge port form a flue, the disaster will be aggravated, spontaneous combustion, explosion happened
[0008] 2. Feeding operation is required on the top of the silo, which must be opened and closed conveniently. There is no similar feeding device disclosed at present

Embodiment Construction

[0024] Figure 1 is a schematic diagram of a safety protection device for a central inerting tubular coal storage silo. Central inerting tubular coal storage silo 1 has a diameter of 10-20 meters and a height of 40 meters. An automatic air-locking funnel device 3, an automatic pressure relief device 4 and a sealing screw feeding device 5 are installed on the top of the silo, and a tubular aeration device 2 is installed at the center of the silo. Above the top of the silo, there is a belt conveyor BELT for transporting materials. The automatic air-locking funnel device is installed on both sides of the belt conveyor, and there are 3-4 on each side of each warehouse, which are used to receive the materials sent by the belt conveyor. The silo mainly relies on the automatic air-locking funnel for feeding. The sealed screw feeding device is set at the tail end of the belt transmission device, that is, under the belt roller, to receive the remaining materials on the belt. The autom...

Abstract

A coal storage silo feeding device comprises automatic air locking funnel devices 3 arranged on the top of a silo and a sealed spiral feeding device body 5. The automatic air locking funnel devices are arranged on the two sides of a conveying belt for conveying materials to the coal storage silo, and the sealed spiral feeding device body of the coal storage silo feeding device is arranged below a roller end of the conveying belt for conveying materials to the top of the coal storage silo. The feeding device has the functions of protecting the materials in the silo and sealing the silo at the same time, and air in the silo can be discharged through the feeding device.

Description

technical field [0001] The invention relates to a coal storage silo feeding device, which is used for feeding and sealing the coal storage silo. Background technique [0002] At present, most coal storage silos are large silos with a diameter of 10-20 meters and a height of 40 meters. The materials are placed in such silos. After long-term storage, the materials will release some sulfur and CH 4 of flammable gases. These gases will be enriched in a large amount in the silo, and the ignition point of coal is low. When the coal reacts slowly in the silo and becomes natural, if the flammable gas in the silo reaches a certain concentration, an explosion will occur, resulting in A security incident occurred. [0003] In order to solve the above problems, it is generally used to fill the silo wall with inert gas (such as nitrogen), so as to reduce the oxygen concentration and flammable gas concentration of the mixed gas in the silo, so that the inside of the silo is kept at the ...
