Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for recovering zinc from zinc waste, comprising a container for zinc waste and a zinc waste crushing device.

Conventionally, equipment for pulverizing zinc waste using a ball mill is generally used.

The construction of such devices screens the material according to particle size but does not separate the granular zinc from the scraps, so on the one hand the degree of effectiveness is low and on the other hand the purity of the recovered zinc is unfavorable.

Furthermore, this device structure generates a large amount of dust, resulting in considerable environmental pollution.

The object of the present invention is to construct the apparatus as mentioned at the beginning, and to achieve the best separation of granular zinc and scraps while preventing the generation of dust and contamination.

The present invention solves the above problems by arranging a vibrating chute combined with an ascending sieve below the crushing device.

Generally, crushing equipment has the structure of a hammer mill,
The special construction according to the invention allows the zinc scrap container to be removably attached to the device and is equipped with a bottom gate which can be operated by means of a lever device.

A screw conveyor is installed below the zinc waste container, and its discharge funnel is placed above the hammer mill.

A filter is coupled to the rising sieve and the vacuum is created by a blower.

The device according to the invention has stable operation and is of high economic value due to its excellent separating effect between zinc and waste.

The device operates fully automatically and does not generate normal dust.

One special structure of the present invention will be described in detail with reference to the accompanying drawings.

The entire device is supported by a frame 1.

A zinc scrap or waste container 2 is removably attached to the device.

This includes a cover 3 serving as a lid and a bottom gate (hinge valve) 4.

The bottom gate 4 can be operated manually or mechanically by means of a lever device 5.

Below the container 2 is a screw conveyor 6, which is driven by a motor 7 via a gear 8.

Since the reduction ratio of the gear 8 can be changed, the output per hour of the screw conveyor can be controlled.

The outlet 9 of the screw conveyor 6 introduces the material into a hammer mill 10 driven by a motor 11.

The material ground in the hammer mill 10 falls into a funnel 12 and then into a vibratory chute 13.

A vibrator 14 connected by a shaft lifts the material through the sieve 1
Send to 5.

In the ascending sieve 15 granular zinc and waste are separated according to their specific gravity.

The air pressure generated by the blower 16 causes the waste in the ascending sieve to rise and be guided to the filtration chamber 17.

Due to its high specific gravity, the granular zinc falls through the rising sieve and is collected below the outlet 18, which is not shown in the figure.

A filtration bag is placed inside the filtration chamber 17, but this is not shown.

There are normally eight filtration bags in the container 17, but there can be more or fewer.

Debris is collected in these filter bags.

The bag is automatically blown up by compressed air so that the waste falls towards the funnel 19.

At the lower end of the funnel 19 is a hydraulic hinged valve 20.

This hinged valve 20 is clocked and opens at regular intervals, so that the waste falls into a container or bag placed below the outlet (receptacle) 21.

The device operates in a fully automatic manner with electrical controls mounted on a switchboard (not shown).

Before operation, first bring the container 2 close to the zinc bath.

Scoop out the zinc waste on the surface of the zinc tank with a shovel commonly used in all galvanizing
Put it in.

This container with a capacity of 500 kg is placed on frame 1 using hoists and nippers.

Open the bottom gate 4 of the container 2 using the lever 5.

The zinc scraps fall onto a screw conveyor 6 and are guided to a hammer mill 10 according to a program.

After being crushed and screened as described above, the granular zinc is removed through the outlet 10 and the remaining scraps are discharged through the inlet 21.
