Embodiment

[0024] like figure 1 As shown, the material bin 2 is provided with a material bin discharge port 21 during normal production, and the material bin discharge port gate 22 can be used to close the material bin discharge port 21, and a hopper inlet is opened from the warehouse wall 20 of the material bin 2. The feed port 30 is installed with a manual flashboard 5, so that the physical object used for verification enters the hopper 3; a hopper discharge port 31 is provided on the warehouse wall 20 at the side of the material bin discharge port 21, and a manual flashboard is installed. 5. It is convenient to discharge material from the hopper 5 to the belt feeding scale 1; the hopper 3 is freely suspended on the material bin 2 through four load cells 4, so as not to affect the accuracy of weighing, and there are weights at the four corners of the bottom of the hopper 3 Hook 6.

[0025] In order to ensure the accuracy of the weighing when calibrating the hopper 3, when doing the st...

Abstract

The invention discloses a belt feeding balance online object calibration device with simple operation and a method; the device comprises a static weighing device which is arranged in arranged in a free suspension state; the material inlet of the static weighing device is communicated with the a material storage bin; the material outlet of the static weighing device is arranged above a belt feeding balance; the static weighing device used in the calibration method is arranged in the free suspension state, the material inlet of the static weighing device is communicated with the material storage bin; and the material outlet of the static weighing device is arranged above the belt feeding balance. The calibration device and the method calibrate the static weighing device firstly carry out the online object calibration on the belt feeding balance by the static weighing device, solve the problem that the material supply of a calciner which is affected by the belt feeding balance online calibration, improve the calibration precision, and can be widely applied to the online object calibration of various belt feeding machines.

Description

technical field [0001] The invention relates to a physical verification method and device of a belt feeding scale, in particular to an online physical verification device and method of a belt feeding scale. Background technique [0002] At present, as a dynamic conveying and measuring equipment, the belt feeding scale is widely used in all walks of life, and its role is particularly prominent in occasions that need to accurately control the amount of material to be discharged. [0003] In aluminum electrolysis production, raw material calcination is one of the very important processes in carbon production. The calcined petroleum coke obtained by calcination directly affects and determines the quality of the anode, which in turn affects the production operation and economic benefits of the electrolytic cell. The pre-calcination of the calcining kiln uses a belt feeding scale, and the feeding port of the material bin is set above the belt feeding scale, and the feeding amount ...
