Automatic float-and-sink test apparatus with linear structure

Abstract

The invention discloses an automatic float-and-sink test apparatus with a linear structure. The automatic float-and-sink test apparatus comprises a plurality of density-level devices which are successively arranged between a pretreatment collecting tank and a gangue collecting tank from left to right in a sequence from low density level to high density level; each density-level device comprises an external water-bath heating tank and a float-and-sink heavy liquid barrel arranged in the water-bath heating tank, the water-bath heating tank is composed of an outer wall of the water-bath heating tank and an inner wall of the water-bath heating tank, and the float-and-sink heavy liquid barrel is composed of an outer wall of the float-and-sink heavy liquid barrel and an inner wall of the float-and-sink heavy liquid barrel; the front side of each water-bath heating tank is provided with a floating-substance collection tank; the rear side of each floating-substance collection tank is provided with a group of a vertically-moving hydraulic cylinder and a short-distance horizontally-moving hydraulic cylinder; the outer side of each water-bath heating tank is provided with a density and pressure determination sensor; and a long-distance horizontally-moving hydraulic cylinder is arranged on the outer side of the gangue collecting tank and perpendicular to the moving direction of the short-distance horizontally-moving hydraulic cylinders. The automatic float-and-sink test apparatus with the linear structure in the invention can carry out layering according to density and separate out corresponding products of each density level.

Description

technical field [0001] The patent of the present invention relates to a kind of float-sink equipment that stratifies materials according to density and automatically separates products corresponding to each density. This float-sink equipment can be widely used in coal washing, iron ore sorting, and non-metallic ore extraction. quality and other fields. Background technique [0002] The resource endowment characteristics of "rich coal, poor oil and little gas" determine the dominant position of coal in my country's energy production and consumption structure, making my country the world's largest coal producer and consumer. Since coal is an organic and inorganic substance It is a complex mixture composed of waste rock components and other harmful components, which need to be separated through coal preparation. At present, the gravity separation process is one of the main processes in coal preparation plants, especially the dense medium coal preparation with many outstanding a...

Problems solved by technology

At present, all floating and sinking experiments need to be completed manually, which is cumbersome and inefficient, and there may be cases where the error exceeds the allowable error of the experiment; in addition, it is difficult to prepare high-density heavy liquid, which is even more difficult in the cold winter, and it is difficult to grow Time to keep the density of the heavy liquid stable after preparation

Especially when there are many coal samples to be processed or the amount of floating and sinking coal samples is large, the labor intensity of the artificial floating and sinking experiment is greatly increased.

Therefore, it is of great significance to develop a floating-sinking equipment that stratifies materials according to density and automatically separates products corresponding to each density to improve the accuracy of floating-sinking experiments, reduce manual labor intensity, and improve work efficiency. There is still little research on this aspect at home and abroad
