Example Embodiment

[0014] The powder stable and controllable conveying device and method of the present invention will be further explained below in conjunction with the accompanying drawings:

[0015] The powder stable and controllable conveying device of the present invention is composed of a front powder box 1, a powder measuring box 2, a screw conveyor 3 and a venturi tube 4.

[0016] Wherein, the side wall of the front powder box 1 is provided with a powder inlet 5, the bottom of the front powder box 1 is provided with a powder outlet 7, and the top of the front powder box 1 is provided with an electric push rod 15. One end is fixed to the top of the front powder tank 1, and the other end is fixed vertically above the powder press plate 6 in the front powder tank 1. The press powder plate 6 should be relatively sealed to the inner side wall of the front powder tank 1 to prevent excess The powder material leaks to the upper part of the powder plate 6, causing pollution and waste. In order to ensu...

Abstract

A stable and controllable powder conveying device and method provided by the invention relate to a conveying device and a method of using the same. The stable and controllable powder conveying device is composed of a pre-located powder box, a powder metering box, a screw conveyor, and a Venturi tube. A powder inlet is formed in a sidewall of the pre-located powder box, while a powder pressing disc is arranged inside the pre-located powder box, and a powder outlet is formed in the bottom of the pre-located powder box; the powder outlet communicates with an inlet of the screw conveyor; an outlet of the screw conveyor communicates with an inlet of the powder metering box; the powder metering box is seated above a weight sensor by means of a support base; an outlet in the bottom of the powder metering box communicates with an inlet of a metering screw pump, and an outlet of the metering screw pump communicates with a material inlet in the top of the Venturi tube; an air inlet of the Venturi tube communicates with an air outlet of a positive pressure fan, and a material outlet of the Venturi tube communicates with a powder conveying pipe that is orderly provided with a microwave powder flowmeter and a switching valve from the material outlet of the Venturi tube. Using multi-stage and fractional conveying, the stable and controllable powder conveying device is capable of improving the conveying efficiency of powder materials and guaranteeing the accuracy of the conveying quantity.

Description

technical field [0001] The invention relates to a conveying device and its usage method, in particular to a stable and controllable powder conveying device and method. Background technique [0002] In many occasions such as the petrochemical industry, it is necessary to quantitatively transport powder materials, but generally, flow meters or weight measurement methods are used to continuously transport powder materials, but once measurement errors occur during continuous transport, it will inevitably affect the follow-up process. The measurement error of conveying powder materials will affect the production process, reduce production efficiency and even cause economic losses. Contents of the invention [0003] The object of the present invention is to provide a stable and controllable powder delivery device and method in order to overcome the above problems. [0004] The stable and controllable powder conveying device of the present invention is composed of a front powder...
