Problems solved by technology

It is not easy to adjust the powder conveying through the blast volume, and the powder flow measuring instrument is expensive. If the experience of using the existing flow-through equipment in the powder flow is considered during use, it may cause greater wear and tear on the measuring instrument. As a result, the measurement accuracy of the measuring instrument will decrease during operation

Embodiment Construction

[0039] specific implementation plan

[0040] According to the needs of the working conditions, the appropriate vibration drop and the rotation speed of the U-shaped groove can be calculated in advance, and the appropriate distribution gas pressure (ie, high-pressure delivery gas pressure) can be set according to the needs of subsequent devices. Fill the silo (1-1) with the conveyable powder described in the invention, start the vibrating screen (1-3) and the motor (2-12) at the same time after the feeding is completed, and set the appropriate vibration drop according to the working conditions Volume and rotation speed (U-shaped groove (2-1)), after the device runs stably (that is, the U-shaped groove is fully loaded), turn on the high-pressure gas with a pre-set flow rate and start conveying.

[0041]In the powder delivery device of the present invention, the vibrating sieve (1-3) shakes off the powder from the silo (1-1), the U-shaped groove (2-1) holds the powder, and the po...

Abstract

The invention relates to a powder conveying device. The device is composed of a powder feeding system A, a powder metering system B and a terminal conveying system, wherein the feeding system A can achieve uniform and stable feeding, and stable operation of the device is guaranteed; the metering system B can be used for converting the metering of the mass (of apparent density of powders and watercontent in general) into the control of the speed under a stable environment, so that the metering becomes simple, feasible and reliable, and continuous and stable operation is realized; and the terminal conveying system C comprises a venturi tube and a cyclone separator, the system design enable the feeding powders can be screened, and the granularity requirement of a powder conveying body can beguaranteed, and the conveying can be completed. The device is simple in structure, continuous and stable in operation, high in automation degree, high in working condition adaptability, energy-savingand environment-friendly; and the device realizes a specific accurate metering function and a screening function, and has a wide industrial and laboratory application prospect.

Description

technical field [0001] The invention relates to a powder conveying device, specifically an integrated device for powder conveying, metering and screening with a certain degree of automation. Background technique [0002] The invention relates to a powder conveying device. With the development of production technology, the types of reactions involved in the production process are becoming more and more diverse. Many production processes involve the participation of powders. For example, in the production of fine chemicals, powders need to enter the reactor as reaction raw materials in the production of cosmetics; In petrochemical production, catalysts involving powder need to play an important role in the reaction, and due to the continuous production process and the non-100% purity of raw materials, it is inevitable to cause loss and failure of the catalyst during the production process. Therefore, it is necessary to With the continuation of production, fresh catalysts are ...
