Description

Unmanned self-discharging electric vehicle for loading and transporting ore sand

Technical Field

The invention relates to the field of conveying of ore sand containing dust, in particular to an unmanned self-discharging electric vehicle for loading and transporting ore sand.

Background

Industrial dust generally refers to dusty industrial waste gas or mechanical processes resulting from damage, sieving, transportation, blasting, etc. in the processing of solid materials, or processes resulting from incineration, high temperature melting, chemical reactions, etc. The former dust contains dust with large particle size and chemical components the same as those of the original solid matter, while the latter contains dust with small particle size and chemical properties and other smoke dust generated by the substances, and the generation of particulate matters can be reduced by improving the production process and the incineration skill. The various industrial dusts are often emitted in the industrial production process, which can damage the air environment of a workshop, harm the physical health of operators, damage the machine equipment of the workshop, and pollute the atmospheric environment to form social public hazard.

In the production of titanium dioxide, titanium ore sand needs to be conveyed to a feed hopper of an ore mill, and equipment with large friction force is not suitable for conveying the titanium ore sand due to the large specific gravity and the large hardness of the titanium ore sand; in addition, the titanium ore sand has much fine dust and is black and black, and the existing solid material layer position sensor is difficult to deal with. Therefore, a small-sized dump truck is generally adopted to convey titanium ore sand, and dust flies during unloading, so that the whole workshop is covered by 'black clouds', thick ore powder is gathered on a floor slab of the workshop, and great harm is brought to the health of workers who work for a long time. In order to improve the air environment of a workshop and avoid air pollution, and ensure that the operation site of workers reaches the sanitary standard, the development of environment-friendly dust-free titanium ore sand conveying automatic control equipment is urgently needed to treat and reduce the dust pollution of the titanium ore sand and prevent the elegant loss of the dust of the titanium ore sand.

No unmanned self-discharging electric vehicle which is disclosed and reported by related documents, is unmanned, can be automatically loaded and unloaded, can automatically go in and out of an environment-friendly dust-free discharging garage, saves investment and is suitable for titanium dioxide production enterprises to load and transport ore sand is discovered up to now.
