Problems solved by technology

Generally, the scraper is in the shape of a rectangular strip. During the sand scraping process, different materials may deform the scraper due to excessive deflection, and the scraper needs to be replaced from time to time.
Zhang Xiaoming disclosed a chain-type sand scraper in "Design and Application of Sand Scraper (Fine Sand Recovery Machine)" on "Equipment Manufacturing Technology" in October 2010. At the bottom of the machine and below the liquid level, it is easy to cause wear or chain jams due to solid particles stuck in the bearings, and it is more troublesome to clean and maintain

Abstract

The invention discloses an environmental-friendly and energy-saving solid-liquid separation device which comprises a tank body, a driving device, a driving wheel device, a riding wheel device, a scraper blade device, a bend wheel device, a strut and a safety rack, wherein the tank body comprises a sliding chute, a guide tank, a front tank body and a rear tank body which are sequentially connected, the driving device is connected with the driving wheel device through a coupling, the driving wheel device is supported at the tail end of the guide tank through a driving wheel bracket, the scraper blade device is divided into an underwater part and an overwater part, the overwater part is supported on the water surface trough the riding wheel device, and a chain ring hook of the scraper blade device is connected with the riding wheel device and the bend wheel device and realizes transmission through the riding wheel device and the driving wheel device. The solid-liquid separation device disclosed by the invention is low in power consumption for processing, and high in solid-liquid separation efficiency; the solid content of effluents is over 60%; the manufacturing cost is low; and the solid-liquid separation device can replace filter presses, spiral classifiers, hydrocyclones, high-frequency vibrating undersize-sieves, dewatering screens, settling ponds and the like and is not equipped with a tailings pond (dam) which occupies a large space land and needs high investment, and tailings can be drily piled and backfilled or can level up land.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an environmentally friendly and energy-saving solid-liquid separation device, which is suitable for solid-liquid separation of various particle sizes. Background technique [0002] Today, when the country and the people have higher and higher requirements for the safety and environmental protection of mine production, the cost of achieving zero discharge of waste water and residue is very high. Tailings, as a by-product of mining ore dressing, is a solid waste that contains pollutants and has a high moisture content. At present, a large number of tailings in my country are mainly stored in tailings ponds without other treatment. Tailings dams have great potential safety hazards, and the danger of dam collapse is very easy to occur. Seeking tailings treatment has become the key to mine development. Dry stacking of tailings after dehydration is one of the tailings treatment met...
