Basket type X-ray machine for measuring cutting height of waste lead-acid storage battery

Abstract

The invention discloses a basket type X-ray machine for measuring a cutting height of a waste lead-acid storage battery. The basket type X-ray machine mainly comprises a roller conveyer, a lead plate housing, a lead curtain, a linear array detector, a basket lifting device and an X-ray source, wherein a U-shaped frame stopper of the basket lifting device protrudes out of the roller surface of the roller conveyer by set height; when the waste lead-acid storage battery is stopped on a U-shaped frame by the stopper, a lower basket frame is triggered to rise up to jack up the waste lead-acid storage battery so that the X-ray source performs transverse linear array scanning on the waste lead-acid storage battery; after scanning, the upper end face of the U-shaped frame falls to be under the roller surface of the roller conveyer, so that the waste lead-acid storage battery on the roller surface can penetrate through the lead plate housing to enter the subsequent treatment line. According to the basket type X-ray machine, an accurate cutting height can be achieved, and the cutting efficiency can be improved. The lead-acid storage batteries of different specifications can be all scanned by a case after entering the device, so that the measurement work on the cutting heights can be completed, and effective data can be provided for the next cutting step.

Description

technical field [0001] The invention relates to the technical field of recycling and processing waste materials, in particular to a device for measuring the cutting height of waste lead-acid batteries. Background technique [0002] In the recycling process of waste lead-acid batteries, in order to avoid the disadvantage of unnecessary loss of precious metals caused by the melting and casting of lead-antimony and lead-calcium during the smelting process, the method of separately recycling lead-calcium alloy and lead-antimony alloy is chosen. Lead-calcium alloys often exist in the grid plate alloy of the pole group, while lead-antimony alloys are distributed in the poles and bus bars. Therefore, according to the structure of the lead-acid battery, it is best to determine the cutting height when dividing the battery. at the root of the bus bar. The root of the bus bar is the link between the bus bar and the grid, and it is also the weakest point in the battery. For the startin...

[0003] The determination of the division point is relatively complicated. Usually, there are three ways to obtain the distance from the root of the bus bar to the bottom of the waste lead-acid battery. One is to use manual measurement. In the presence of dilute sulfuric acid, the cutting process will inevitably require a great deal of manpower and material resources; the second is to cooperate with lead-acid battery design and manufacturing companies to obtain relevant data, but this process may involve some corporate secrets, and the actual cost Not small; the third method uses X-ray machine for scanning. This method has the highest efficiency under the premise of cost control, and is also widely accepted by lead-acid battery recyclers

However, common X-ray scanners use longitudinal or vertical line array scanning. Due to the compact structure of the bus bar root and the influence of the width of the battery and the height of the X-ray source on imaging, the scanned image often cannot distinguish the cutting height, resulting in inaccurate distance measurement.
