Abstract

The invention discloses a slime water microbubble classifying and desliming device. The device comprises multiple cylinders which are connected in series. The upper end of the first cylinder is provided with a feeding pipe in the tangential direction. The multiple cylinders are connected through connecting pipes at the top ends. The top end of the final-stage cylinder is provided with a discharging pipe in the tangential direction. The lower end of any cylinder is provided with a bubble generation device. The bottom end of the lower side of each bubble generation device is connected with a bottom flowing pipe and a discharging valve. The head ends of the connecting pipes between the cylinders are arranged in the flowing-out direction of slime water, and the tail ends of the connecting pipes between the cylinders are arranged in the flowing-in direction of the slime water. The bubble generation devices are arranged to be multiple hollow pipes which are interwoven in a net shape and communicate with one another, and air holes are evenly distributed in the upward faces of the hollow pipes. The diameters of the cylinders are gradually reduced from the first stage to the final stage. The slime water microbubble classifying and desliming device is simple in structure, stable in running and capable of ensuring the slime water treatment efficiency and meanwhile ensuring the slime water treatment effect.

Description

Technical field [0001] The invention belongs to the technical field of slime water flotation, and specifically relates to a slime water microbubble classification and desliming device. Background technique [0002] The slime water is the medium water produced in the process of coal separation and processing. The slime water is one of the main pollution sources in the coal industry. The main task and purpose of the slime water treatment system is to recover fine particles of different quality from the huge amount of slime water. Whether the product and the recycled water suitable for the coal preparation plant can realize the closed loop of washing water, and whether it can meet the requirements of environmental protection when discharged will seriously affect the economic and social benefits of the coal preparation plant. Therefore, the treatment of slime water is a very important link in the production process of the coal preparation plant. In the prior art, the slime water is ...
