Embodiment Construction

[0009] Below in conjunction with example and accompanying drawing, the present invention is described in further detail.

[0010] A micro-feeding device provided by the invention comprises a feeding unit and a pulse auxiliary unit. Feeding unit as attached figure 1 As shown above, the support platform 6 is fixed by the support column 14, which is convenient for placing various components. The upper rotating platform 2 is located above the supporting platform 6 . The feeding hopper 1 is fixed above the upper rotary table 2 by a bracket 16 . For the convenience of installation, the bracket 16 is fixed above the support platform 6 through the support rod 15 . The shape of the feed hopper 1 is a truncated cone, which is convenient for pouring samples, and can also control the quality of the samples falling on the upper rotary table 2. The upper rotary table 2 is connected with the first motor 8, and its uniform rotation is controlled by the first motor 8. The rotation shafts ...

Abstract

The invention discloses continuous and impulse type trace feeder device. Upper rotating table is set above the supporting table. Truncated cone shape hopper is set above the upper rotating table. The first, border, and second scraper blades are orderly arranged along the upper rotating table. The first scraper blade is connected to surplus recovery tank. The upper and lower rotating table is connected to electric machinery. Funnel feed pipe is set between the second scraper blade and the lower rotating table. And the latter is set sector gap and the third scraper blade. It has the advantages of high stability and precision, adjustable feed rate, controlled impulse, and so on.

Description

technical field [0001] The invention belongs to the technical field of pulverized coal, biomass and waste combustion, and relates to micro-feeding in the research of pulverized coal and biomass combustion and waste incineration, in particular to a continuous and pulse micro-feeding device. Background technique [0002] In laboratory research and industrial fields, quantitative, stable and precise feeding is often required. At present, the accuracy of the common feeding device can meet the requirements in the case of normal feeding (greater than 1g / min), but there is poor accuracy and stability in the case of micro-feeding (less than 1g / min). Especially in laboratory research, it is often necessary to meet the feeding amount of about 0.1g / min. Due to the small feeding amount, the accuracy and stability must be satisfied at the same time, which is difficult to achieve with ordinary feeding devices. [0003] On the other hand, in the combustion of pulverized coal and waste inc...
