Abstract

The invention discloses a bucket-type coal quantity weighing metering device for an industrial fire coal chain-grate boiler. A coaling bucket is installed in a coal discharging pit. A lifting motor is installed above the coal discharging pit. Vertical guide rails are arranged on the two sides between the coal discharging pit and the lifting motor. Fixed pulleys and upper and lower pulleys are fixedly connected with the two sides of the coaling bucket, the upper and the lower pulleys are embedded in the vertical guide rails and move, and the fixed pulleys and support pulleys are in rigid connection through a pulley support. The lifting motor is fixed on a fixing support and connected with the support pulleys arranged on the coaling bucket through a steel wire rope and drives the coaling bucket to lift. The weighing coal bucket is horizontally installed on the fixing support and provided with a weighing sensor. The weighing sensor is connected with a measuring control cabinet. The bottom of the weighing coal bucket is provided with a gate which is used for discharging the coal, and the bottom of the gate is a boiler coal bucket. The bucket-type coal quantity weighing metering device for the industrial fire coal chain-grate boiler can automatically weigh, meter and discharge the coaling of each bucket, tries not to change the original bucket-type lifting structure and circuit, and is simple in structure and convenient to operate.

Description

technical field [0001] The invention belongs to an industrial weighing and measuring device, in particular to an industrial coal-burning chain boiler bucket type coal weighing and measuring device in the field of coal measuring. 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 boilers, especially industrial coal-fired chain boilers equipped with bucket-type coal loading equipment, generally use manual weighing methods. 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 deficiencie...
