Embodiment Construction

[0013] like figure 1 and figure 2 As shown, a weighing module of the present invention includes a load cell electrically connected to the weighing system, and the load cell is a common pressure sensor that can convert pressure into an electrical signal; the load cell includes a pressure sensor element 1. The original used to convert pressure into electrical signal. The upper end of the pressure sensing element 1 is wrapped with a guide 2, and a guide groove is arranged in the guide 2, and the guide groove is used to limit the movement path of the pressure head 3 for placing the coal scuttle so that it can only move vertically. The lower end of the pressure head part 3 is in contact with the pressure sensing element 1 and can directly transmit the pressure of the coal scuttle to the pressure sensing element 1 . A rolling bearing 4 is welded on the upper end of the pressure head member 3, and the rolling bearing 4 is used to place the coal scuttle, and the position of the coa...

Abstract

The invention relates to a weighing module which comprises a weighing sensor connected with a weighing system, wherein the weighing sensor comprises a pressure sensing element, a pressure head member for placing weights and a guiding member for positioning the vertical movement of the pressure head member, wherein a guiding slot is arranged in the guiding member; the pressure head member can upward and downward slide along the guiding slot; the lower end of the pressure head member comes into contact with the pressure sensing element; and the upper end of the pressure head member is provided with rolling device for making the weights placed on the pressure head member slide. The pressure head member of the weighing module is provided with a rolling bearing which can adjust the position of a coal bucket for weighing. When the coal bucket is not placed on the rolling bearing in the standard weighing position, the slide friction between the coal bucket and the pressure head member in the prior art can be changed into rolling friction by the rotation of a rolling spindle so as to easily correct the weighing position of the coal bucket, reduce the abrasion of the pressure head member, and improve the weighing accuracy.

Description

technical field [0001] The present invention relates to a weighing module for a coal-fired weighing load sensor to be installed in the weighing module. Background technique [0002] Depending on the type of load cell used and the required load range, weigh modules can be used in different fields of application. Weigh modules with load cells for high loads are mainly used to determine the weight and weigh the contents of high volume containers, silos, tanks, reactors or reaction vessels. [0003] At present, the weighing module of the coal-fired weighing load sensor of the coal-fired boiler is mainly composed of a pressure sensor, and the coal hopper that releases the coal is placed on the weighing module for direct weighing. During the weighing process, the contact position between the bottom of the coal hopper and the sensor will shift, and the measured value will deviate, which is not conducive to accurate weighing of the coal. [0004] Therefore, it is necessary to prov...
