Coal fired boiler belt conveying type coal quantity weighing metering device

Abstract

The invention discloses a coal fired boiler belt conveying type coal quantity weighing metering device. A coal unloading pit is internally provided with a weighing coal hopper, the coal weighing hopper is installed on the front portion of the coal unloading pit, a coal conveying vehicle is located on the ground of one side outside the coal unloading pit, coal of the coal conveying vehicle is poured into the coal weighing hopper, a boiler coal hopper is located on the ground of the other side of the coal unloading pit, and a belt conveying device is installed between the coal weighing hopper and the boiler coal hopper; a weighing sensor is installed on the coal weighing hopper, the weighing sensor is connected with a metering control cabinet, and the weighing sensor collects weight data and transmits the data to the metering control cabinet; the bottom of the coal weighing hopper is provided with a gate, and a coal guide groove of a belt conveying machine is located below the gate. According to the coal fired boiler belt conveying type coal quantity weighing metering device, original hopper-type coal feeding equipment is changed into the belt conveying type coal feeding equipment, the fired coal weighing device and the coal quantity metering control cabinet are added, each hopper of feeding coal can be automatically weighed, and the automatic metering is conducted, the automatic coal releasing and the automatic conveying are achieved, the structure is simple, the operation is convenient, and the coal fired boiler belt conveying type coal quantity weighing metering device is suitable for both coal fired boilers of batch-type coal feeding modes and coal fired boilers of continuous coal feeding modes.

Description

technical field [0001] The invention belongs to an industrial weighing and metering device, in particular to a coal-fired boiler belt conveying coal weighing and metering device in the field of coal metering. Background technique [0002] Coal consumption is an essential parameter for the calculation of the positive equilibrium thermal efficiency of coal-fired boilers and the calculation of commercial operating costs. Traditional coal-fired boiler coal weighing measurement is generally a manual weighing method. Each time the fireman pushes the coal truck loaded with coal to weigh the coal through the scale, and then records it. The manual weighing measurement method has problems such as unsustainable and prone to errors due to the accuracy of the scale and the responsibility of the fireman (missing weighing). Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned background technology, the present invention proposes a coal-fired b...
