A basket-type x-ray machine for measuring the cutting height of waste lead-acid batteries

Abstract

The invention discloses a basket-type X-ray machine for measuring the cutting height of waste lead-acid batteries. It mainly includes roller conveyor, lead plate casing, lead curtain, linear array detector, lifting basket device, X-ray source; the U-shaped frame stopper of the lifting basket device protrudes from the roller surface of the roller conveyor to set Height, and when the waste lead-acid battery stays on the U-shaped frame because of the stopper, the lower frame of the gondola is triggered to rise and the waste lead-acid battery is lifted up for the X-ray source to perform horizontal linear scan. After the scan is completed, all The upper end surface of the U-shaped frame falls below the roller surface of the roller conveyor to facilitate the waste lead-acid batteries carried by the roller surface to pass through the lead plate casing and enter the follow-up processing line. Accurate cutting height can be obtained while improving cutting efficiency. After the lead-acid batteries of different specifications enter the device, they can be scanned by the chassis to complete the measurement of the cutting height and provide effective data for the next step of cutting.

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.
