Embodiment

[0027] Such as figure 1 As shown, the high-precision powder quantitative feeder of the present invention includes a feeding pipe 1, a disc feeder 2, a weighing mechanism 3, and a discharging mechanism 4.

[0028] A flap valve 11 is set on the feeding pipe 1, such as figure 2 , image 3 , Figure 4 As shown, the flap valve 11 includes a flap shaft 112, a flap 113 is arranged on the flap shaft 112, the flap 113 is divided into a first flap and a second flap, and the first flap and the second flap are symmetrically arranged on Both sides of the turning shaft 112 are fixedly connected with the turning shaft 112 . The angle between the first flap and the second flap is 180°, and the size and shape of the first flap and the second flap should be set to match the feeding pipe, that is, when the first flap and the second flap When the boards are all in a horizontal state, the feeding pipe is just closed. One end of the turnover plate rotating shaft 112 exposes the pipe wall of t...

Abstract

The invention discloses a high-precision powder quantitative feeding machine, in order to solve the problems of instability in weighing and poor metering precision caused by a larger error of a metering screw because powder materials usually run through a feeding screw due to overlarge bin pressure when a double-screw meter is adopted to weigh in the prior art. The high-precision powder quantitative feeding machine disclosed by the invention comprises a feeding pipe, a feeding mechanism, a weighing mechanism and a discharging mechanism, wherein the feeding pipe, the feeding mechanism, the weighing mechanism and the discharging mechanism are connected in sequence; a feeding valve used for controlling the feeding speed is arranged on the feeding pipe; the feeding mechanism is a rotary disc feeding machine and is used for further relieving pressure, so as to be convenient for materials to stably flow into; a scraping device is arranged in the weighing mechanism to prevent the materials from remaining on the inner wall of a weighing bin; the discharging mechanism is a double-screw conveyer which is arranged in the weighing bin, the materials are output by the double-screw conveyer, so as to realize thick and thin flow control; in addition, a gate valve is arranged in an output port of the double-screw conveyer. The high-precision powder quantitative feeding machine disclosed by the invention has the advantages of simple structure and high precision, and the thick and thin flow control can be realized.

Description

technical field [0001] The invention relates to the technical field of powder feeders, in particular to a high-precision powder quantitative feeder. Background technique [0002] Quantitative feeder is an ideal equipment for continuous weighing and feeding of bulk materials. It is a high-tech product integrating conveying, weighing measurement and quantitative control. It is famous for its advanced technology, stability and reliability, high cost performance and durability. . It can adapt to various production environments, continuously feed and measure various block, granular materials (such as limestone, iron powder, clay) and powdery materials (such as fly ash, cement), etc., and is suitable for various industrial sites. Control and management provide accurate measurement data. [0003] Quantitative feeder is widely used in building materials, metallurgy, electric power, chemical industry, coal, coking, mining, tobacco, grain, environmental protection, port and other in...
