Technical Field

[0001] The invention relates to the technical field of explosive production equipment, in particular to an automatic storage and conveying device for industrial explosive additives. Background Art

[0002] Powdered emulsion explosive is an explosive material used in mining, civil engineering and other fields. Its main component is the powder form of emulsion explosive. Emulsion explosives are usually mixed with oil, water and oxidizer, and are emulsified to form a stable emulsion. Powdered emulsion explosives are made into powder form for easy storage and transportation, and can be remade into a form suitable for use when needed. Powdered emulsion explosives need to add talcum powder to the production system in a specified proportion during the production process.

[0003] At present, due to the large demand for talcum powder, the talcum powder on site is generally stored in large outdoor storage tanks. When producing powdered emulsion explosives, it is necessary to manually transfer the talcum powder in the outdoor storage tanks to the indoor buffer warehouse for standby use via material trucks. However, during the transportation process of the material trucks, the talcum powder is prone to dust, causing environmental pollution and air quality problems. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, comprising: a storage tank, which is used to store talcum powder; an air-solid conveying pump, which is arranged below the storage tank and is connected to a feeding pipe; a buffer bin, which is connected to the air-solid conveying pump through the feeding pipe; a quantitative conveying pump, which is connected below the buffer bin and is provided with a feeding pipe; and a dust collector, which is arranged above the storage tank.

[0005] As a further description of the above technical solution: an air storage tank is arranged on one side of the storage tank, the air storage tank is connected to the gas-solid conveying pump through a first air pipe, and the air storage tank is connected to the dust collector through a second air pipe.

[0011] As a further description of the above technical solution: the first cover body and the second cover body are both provided with air inlets, the air inlets are connected to the air inlet pipe group, and the air inlet pipe group is connected to the air storage tank.

[0012] As a further description of the above technical solution: sealing gaskets are provided inside the first discharge pipe and the second discharge pipe.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] 1. The present invention uses a gas-solid conveying pump located below the storage tank, and conveys talcum powder from the storage tank to the buffer bin through a feeding pipe. The gas-solid conveying pump can effectively transfer talcum powder from the storage tank to the buffer bin, ensuring the efficiency and continuity of the material conveying process, and no material truck is required to transport the material to avoid dust.
