Waste collecting device for vanadium extraction wastewater treatment and using method thereof

Abstract

The invention discloses a waste collecting device for vanadium extraction wastewater treatment and a using method thereof. The waste collecting device comprises a collecting box, wherein the top of the collecting box is fixedly connected with a feeding hopper; the outer part of the collecting box is fixedly connected with a motor; a first crushing mechanism is arranged inside the collecting box; a second crushing mechanism is arranged below the first crushing mechanism; a material conveying mechanism is arranged on one side of the second crushing mechanism; a transmission mechanism is arranged on the other side of the second crushing mechanism; a screening mechanism is arranged below the second crushing mechanism; and a collecting mechanism is arranged below the screening mechanism. The waste collecting device has the beneficial effects that waste can be crushed for multiple times, so that the crushing is more thorough, the waste crushed for multiple times can be screened, the screened waste can be conveyed and crushed again, the crushing quality is effectively improved, the crushed material can meet the expected requirements, the collecting standard is met, and therefore the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of collection devices, in particular to a waste collection device for vanadium extraction wastewater treatment and a use method thereof. Background technique [0002] Before the vanadium-containing molten iron enters the steelmaking process, the molten iron pretreatment process is to oxidize vanadium in the molten iron into vanadium slag and separate it from the molten iron, also known as pyrotechnic vanadium extraction. When blowing air or oxygen into molten iron, vanadium in molten iron must be oxidized rapidly and preferentially, while other components are less oxidized, so that vanadium slag with high vanadium content can be obtained. During the blowing process, carbon oxidation in molten iron should be minimized to ensure that There is still enough heat of chemical reaction when semi-steel is made. [0003] In the process of vanadium extraction wastewater treatment, it is often necessary to use a colle...

Problems solved by technology

[0003] In the process of vanadium extraction wastewater treatment, it is often necessary to use a collection device to collect waste blocks. Although the existing waste collection device can crush the collected waste to achieve the purpose of convenient storage and recycling, the crushing mechanism is too large. It is simple, and can only crush the waste block once, resulting in incomplete waste crushing. At the same time, the traditional collection device cannot screen the crushed waste, and cannot crush the screened waste block again, so that after crushing The waste does not meet the expected requirements and does not meet the collection standards, which greatly reduces the crushing quality and increases the cost
