Problems solved by technology

[0009] (3) The adjustment of the material layer at the feed port is non-automatic manual adjustment, and manual adjustment of the material layer at the feed port is labor-intensive and time-consuming
[0010] (4) The control mode is single, which is not conducive to user selection;
[0011] (5) The load cell is an analog load cell. When the long-distance weighing data is transmitted, the anti-interference ability is poor

Embodiment Construction

[0062] The specific implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples, but the protection scope of the present invention should not be limited thereby.

[0063] see Figure 9-1 , Figure 9-2 , Figure 9-3 , Figure 10, Figure 11 , Figure 12, Figure 13.

[0064] The present invention is based on the multi-material belt weighing system of a belt conveyor, comprising a belt conveyor 17 ( Figure 9-3 ) and the three feeding ports 1, 2, 3 above the belt conveyor ( Figure 9-2 ), the whole belt conveyor consists of a sealed shell body 5 ( Figure 9-2 ) protection, inspection window 4 ( Figure 9-2 ) is used for daily inspection and maintenance of equipment, and there are 2 sets of explosion-proof lighting devices 8 ( Figure 9-2 ) for internal maintenance. The belt conveyor includes three sets of weighing devices for material measurement, a set of speed sensor 9 ( Figure 9-2 )...

Abstract

The invention discloses a belt conveyor based multi-material belt weighing system, which comprises a belt conveyor and a plurality of feed inlets above the belt conveyor. The belt conveyor comprises a plurality of weighing devices for metering materials, a speed measuring sensor, a main drive motor and an integrating control instrument, wherein each weighing device comprises a metering roller and two weighing sensors; and the weighing sensors transmit weight signals to the integrating control instrument. Different or same materials are filled through the plurality of feed inlets; the plurality of weighing devices are arranged in front of the running direction of a belt respectively; and the integrating control instrument meters the instantaneous flow respectively so as to realize the continuous and accumulated multi-material weighing or the quantitative-control continuous and accumulated multi-material weighing on one belt conveyor.

Description

technical field [0001] The invention relates to a measuring and weighing device, in particular to a multi-material belt weighing system based on a belt conveyor, which is especially suitable for belt scales in building materials industry systems that require multi-material batching and thermal power plants that need to reduce the height of silos. Silo pressure-resistant metering coal feeder. Background technique [0002] The continuous cumulative automatic belt scale uses the weight sensor to detect the instantaneous weight signal of the unit length of the material, and the speed sensor detects the speed pulse signal at the same time. Through the control system, the weight signal and the speed signal are multiplied to obtain the real flow (transport volume) of the material to be weighed. [0003] The continuous cumulative quantitative automatic belt scale is based on the above real flow, so that the control system will compare the real flow of the material to be measured wi...
