Problems solved by technology

Since traditional coal-fired boilers do not have the function of measuring coal consumption, it is difficult to calculate accurately
The usual method is to count the time of coal burning when the total amount of coal is known, and then roughly calculate the efficiency of coal burning; The weight of coal in the boiler is then calculated, but such a weighing process wastes a lot of manpower, time and energy, and manual intervention often leads to measurement errors

Embodiment 1

[0015] Such as figure 1 , figure 2 As shown, there is no coal-fired metering device for existing coal-fired boilers. When the weighing of the coal hopper is within 1000kg, a coal-fired boiler metering device is provided, including coal hopper 4, guide wheel 6, guide rail 7, Support rod 2, steel wire sling 1, tension sensor 3 and the control instrument connected to the tension sensor, steel wire sling 1 is connected to support rod 2, support rod 2 is hinged on coal bucket 4, and guide wheel 6 is fixedly installed on the coal hopper. The bucket 4 can slide stably along the guide rail 7, and the tension sensor 3 is connected in series with the steel wire rope 1 through a steel ring.

[0016] Weighing method: When the steel wire rope 1 lifts the coal bucket 4 and rises at a constant speed along the guide rail 7, the tension of the steel wire rope 1 is transmitted to the support rod 2 and the coal bucket 4 through the tension sensor 3. During this process, the tension sensor 3 is...

Embodiment 2

[0018] Such as image 3 As shown, in view of the existing coal-fired boiler without coal-fired metering device, when the weighing of the coal hopper is within 500kg, a coal-fired boiler metering device is provided, including coal hopper 4, support rod 2, and steel wire rope 1. The tension sensor 3 and the control instrument connected to the tension sensor, the steel wire sling 1 is connected to the support rod 2, the support rod 2 is hinged on the coal bucket 4, and the tension sensor 3 is connected in series to the steel wire sling 1 through the flange superior.

[0019] The specific weighing calculation process is the same as in Embodiment 1.

Embodiment 3

[0021] Such as figure 2 , Figure 4 As shown, there is no coal-fired metering device for existing coal-fired boilers. When the weighing conditions of the coal hoppers are complicated and changeable, a coal-fired boiler metering device is provided, including coal hoppers 4, guide wheels 6, guide rails 7, Support rod 2, steel wire sling 1, tension sensor 3 and the control instrument connected to the tension sensor, the steel wire sling 1 is connected to the support rod 2, the support rod 2 is hinged on the coal bucket 4, and the tension sensor 3 constitutes the hinged coal bucket And the axle pin of support bar, guide wheel 6 is fixedly installed on the coal bucket 4 and can slide steadily along guide rail 7.

[0022] The specific weighing calculation process is the same as in Embodiment 1.

Abstract

The invention relates to the field of coal-fired boilers, in particular to a device for weighing and measuring a coal-fired boiler. The technical problem to be solved is to provide a coal-fired boiler measuring system which has the advantages of saving a great deal of labor, time and energy, along with convenient use and accurate measurement. The coal-fired boiler measuring system comprises a coal bucket, a support bar and a wire sling. The wire sling is connected to the support bar which is hinged on the coal bucket. The coal-fired boiler measuring system also comprises a tension sensor for weighing and a control instrument which is connected to the tension sensor. The tension sensor can be connected in series with the wire sling, or fixedly connected in series with the support bar, or arranged on a pin shaft of the support bar and the coal bucket. The coal-fired boiler provided with the measuring device has the advantages of convenient use and accurate measurement in the aspect of measuring the consumption of fire coal, and the labor, time and energy can be greatly saved simultaneously.

Description

technical field [0001] The invention relates to the field of coal-fired boilers, in particular to a weighing and measuring device for coal-fired boilers. Background technique [0002] As a commonly used steam and hot water generating device, coal-fired boilers are widely used in various industries. Since traditional coal-fired boilers do not have the function of measuring coal consumption, it is difficult to calculate accurately. The usual method is to count the time of coal burning when the total amount of coal is known, and then roughly calculate the efficiency of coal burning; The weight of coal in the boiler is then calculated, but such a weighing process wastes a lot of manpower, time and energy, and manual intervention often leads to measurement errors. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a metering system for boiler coal consumption that is convenient to use, accurate in metering, and saves a...
