Background
Inorganic substances such as silica and calcium carbonate, and resin-based powders such as vinyl chloride and terephthalic acid are widely used and are transported in principle by using flexible bulk bags.
Among the above substances, fumed silica has a very low bulk density of about 40 to 100g/L, and therefore, when powder is extracted from a flexible container, if the outlet of the flexible container is directly opened and extracted, dust flies. In order to solve this problem, a self-contained powder pump is used, and a powder pump suction part and a flexible container bag discharge port are connected by a hose to extract powder, so that dust can be prevented from flying in the air.
Since fumed silica has a very small primary particle diameter, is easily adhered to the container, and has a high cohesiveness, there is a problem that if a large amount of powder is discharged from a flexible container at one time, the powder in the powder pump is compressed and clogged. In addition, in order to prevent clogging, a gas such as dry air may be introduced through a line below the discharge port of the flexible container bag, but if the distance between the discharge port of the flexible container bag and the powder pump is too short, the powder and the gas may not be sufficiently mixed, and the inside of the powder pump may be clogged. There is a need for a highly efficient tool for extracting powder from flexible bulk bags.

Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example one
As shown in fig. 1 to 3, the device for extracting powder according to the embodiment of the present invention includes an inner tube 1 having a powder inlet and a powder outlet 5 at both ends, an outer tube 2 is sleeved on a middle portion of the inner tube 1, an inner cavity having both ends closed is formed between an inner ring of the outer tube 2 and an outer wall of the inner tube 1, and a gas introduction tube 3 is communicatively fixed on the outer wall of the outer tube 2. The side wall of the inner cylinder 1 is provided with a plurality of air blowing holes 6 communicated with the inner cavity, the inner diameter of the outer cylinder 2 is larger than the outer diameter of the inner cylinder 1, and the joint of the two ends of the outer cylinder 2 and the inner cylinder 1 is sealed by welding, so that the inner cavity with two sealed ends is formed between the outer cylinder 2 and the inner cylinder 1, and the air inlet pipe 3 is communicated with the inside of the inner cylinder 1 through the plurality of air blowing holes 6. The powder filling port 4 of the inner barrel 1 is connected with the outlet of the flexible container bag, the powder outlet 5 is connected with the self-supply pump suction part, so that the powder enters from the powder filling port 4, is discharged from the powder outlet 5, is conveyed by the self-supply type powder pump, simultaneously introduces gas into the outer barrel 2 through the gas introduction pipe 3, and introduces gas into the inner barrel 1 through the blowing hole 6, thereby avoiding the powder blockage in the powder pump and improving the powder extraction efficiency.
In order to increase the anti-blocking effect, the plurality of air blowing holes 6 are uniformly distributed on the inner cylinder 1 at equal intervals in an annular manner, so that air can be uniformly blown into the inner cylinder 1 from the periphery of the inner cylinder 1.
