Problems solved by technology

Before, the inventor proposed a weighing device for coal-fired boilers with bottom weighing. The weight of coal added to the coal-fired boiler through the coal hopper often needs to be weighed by the weighing device first, which increases the weight of adding coal invisibly. At the same time, there are still errors and complicated procedures when the coal is added from the weighing device to the coal scuttle after weighing

Abstract

The invention relates to a coal-fired boiler metering and weighing device which comprises a coal bucket with a rotatable rocker arm, a bracket with a rotary joint matched with the rocker arm and a simple beam located at the top of the bracket and connected with the rocker arm through a lifting rope. The bracket is provided with a support rod which is located right below the coal bucket and provided with a bottom weighing sensor, a pressure sensor is arranged on the simple beam, an axle pin sensor is arranged at a position where the rocker arm and the coal bucket are pivoted, and all the sensors are respectively connected with a weighing control system. The weight of coal in the coal bucket can be measured through the bottom weighing sensor arranged at the bottom of the coal bucket, the axle pin sensor arranged at the position where the rocker arm and the coal bucket are pivoted and an S-shaped sensor arranged at the top of the bracket, and the cheating practice of weighing just the bottom when the coal bucket does not fall to the ground completely can also be prevented.

Description

technical field [0001] The invention relates to a discontinuous feeding coal-fired boiler, in particular to a weighing device for discontinuous feeding coal-fired boiler. Background technique [0002] As a commonly used steam and hot water generating device, coal-fired boilers are widely used in various industries. Before, the inventor proposed a weighing device for coal-fired boilers with bottom weighing. The weight of coal added to the coal-fired boiler through the coal hopper often needs to be weighed by the weighing device first, which increases the weight of adding coal invisibly. At the same time, there are still errors and complicated procedures in operation when the coal is added from the weighing device to the coal hopper after weighing. [0003] Therefore, there is an urgent need to provide a coal-fired boiler metering and weighing device, which can weigh the coal loaded in the process of adding coal to the coal hopper, and can effectively prevent the weighing pro...
