Background

In the ISA technological process of electrolytic refining in the copper smelting industry, a stainless steel cathode plate is used as a cathode, blister copper is used as an anode, and cathode copper is adsorbed on the cathode plate in the electrolytic process. And (3) producing by a stripping unit after the adsorption period is reached, stripping the cathode copper and the cathode plate at a stripping station of the stripping unit, overturning the cathode copper from a vertical state to the water surface by a plate turnover device and placing the cathode copper on a conveying chain, conveying the stripped cathode copper to a stacker crane by the conveying chain to stack single cathode copper, judging whether stacking is finished according to the set number of sheets, packaging output of the stacked cathode copper, and finally weighing for sale. The weight range of the piled cathode copper is required to be between 2000KG and 3000KG in the distribution process, and the weight range of the outlet copper is strictly between 2400KG and 2600 KG.

In the production process of electrolytic refining, because the electrical efficiency of each tank is different, the weight of cathode copper adsorbed from each tank is different, and especially when a plurality of short circuits occur in a single tank, the weight deviation of the cathode copper in the single tank is larger. The existing equipment structure does not have a mechanism for weighing a single piece of cathode copper or calculating the weight in the stacking process, the weight of the chopped cathode copper can be known only by feeding back data after the chopped cathode copper is weighed by a forklift in the production process, and the cathode copper in another groove is produced by a stripping unit at the moment, if the number of stacked pieces is adjusted, the weight of each groove is different, so that the weight of the cathode copper which is being stacked can be out of range. This leads to a hysteresis in the weight data, especially during the copper inventory export, which is more problematic and severely impacts the inventory yield.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.

Example 1

The embodiment provides a single-cathode copper weighing device, which comprises a weighing base 6, a movable tray 4, a bearing with a seat 7 and a weighing sensor 5, as shown in figures 1-2; the bottom of the movable tray 4 is provided with a tray cantilever 41; the tray cantilever 41 is L-shaped, one end of the vertical part of the tray cantilever is connected to the center of the bottom of the movable tray 4, one end of the transverse part of the tray cantilever is connected with a rotating shaft 8, two ends of the rotating shaft 8 are respectively connected to a bearing with a seat 7, and the bearing with a seat 7 is fixed at one end of the weighing base 6; the right lower part of the center of the movable tray 4 is contacted with a weighing sensor 5 through a steel ball 9, and the weighing sensor 5 is fixed on a weighing base 6.

When a single piece of cathode copper to be weighed falls on the movable tray, the gravity acting on the movable tray is transmitted to the weighing sensor through the steel ball.

In this embodiment, the two ends of the movable tray 4 are respectively provided with a downwardly inclined guide plate 43. The guide plate 43 serves to guide the cathode copper into or out of the movable tray.

In this embodiment, the vertical part of the tray cantilever 41 is H-shaped, and the bottom center of the beam of the H-shaped vertical part corresponds to the center of the movable tray 4 and is in contact with the load cell 5 through the steel ball 9.

Example 2

This example provides an example of the use of the monolithic cathode copper weighing apparatus described in example 1.

As shown in fig. 3-4, the weighing base 6 is installed inside the existing conveyor chain frame 1, and is better integrated into the existing stripping unit production line.

Specifically, the uppermost surface of the movable tray 4 is made higher than the conveyor chain, so that the cathode copper 3 conveyed by the conveyor chain is made to pass through the slope of the guide plate 43 to make the cathode copper 3 and the conveyor chain 2 overhead, and the weight of the cathode copper 3 is made to completely act on the movable tray 4. The rear end of the conveying chain 2 is provided with a protruding chain plate, so that the forward acting force of the chain acts on the cathode copper through the protruding chain plate, and the cathode copper is driven by the acting force to ascend through the guide plate 43. During the overhead movement, horizontal advancing acting force is generated due to the cathode copper which runs horizontally, and when the acting force passes through the guide plate, the acting force can be decomposed into vertical downward acting force and horizontal advancing acting force, but the weighing sensor cannot bear excessive horizontal transverse acting force. According to the rotation characteristic of the bearing with the seat, the original horizontal acting force is counteracted in the bearing with the seat through the action of the cantilever and the rotating shaft. At the same time, only a downward gravitational force is generated after the cathode copper is at rest, and this gravitational force acts directly on the weighing cell, i.e. the measured weight of the individual cathode copper. And then, the weighing sensor is connected with an instrument for displaying, so that an operator can know the weight of the cathode copper of each block at any time, and the number of stacking blocks is set according to the weight. So that the cathode copper reaching each pack of stacks is within the weight range.

Various corresponding changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
