Full automatic high-efficiency pipe chute thickener

Abstract

The invention discloses a full-automatic high-efficiency inclined tube thickener; wherein, two ends of a bridge frame are fixed on a round concrete pool, and the bottom in the pool is designed to be a taper shape, and a central column provided with an outer wall wrapped by a steel tube is erected at the center of the pool bottom, and the upper end of the central column is connected with the middle of the bridge frame through a central shaft. The central column and the central shaft are respectively connected with the pool bottom and the bridge frame through bearings. An electric-control cabinet and a hydraulic station which are arranged on the bridge frame are connected with the upper end of the central shaft through a driving rake-lifting device. A steady flow barrel is arranged on the outer side of the central shaft, and a shaving-collecting device is fixed on the outer wall of the central column. An inclined brace is extended from the central shaft to be connected with the shaving-collecting device. Inclined tube brackets are arranged along the wall of an inner cavity of the round concrete pool and the whole section face, and then glass reinforced plastic beehive inclined tubes are arranged on the base of the inclined tube brackets. Compared with the prior art, the full-automatic high-efficiency inclined tube thickener of the invention has the beneficial effects that a backwash settlement is adopted and is proper; the occupying area is small and the settlement area is big; three zones are distinct and the settlement effect is better; the settlement time is short and the manufacturing cost can be conserved; accident hidden troubles can be eliminated to guarantee a normal running; the mechanical mechanism is excellent and the running is stable; the glass reinforced plastic inclined tube has high intensity and is anti-aging and anti-corrosion; the management is convenient and automatic control of the whole process can be realized.

Description

technical field [0001] The invention relates to a concentrator, in particular to a full-automatic high-efficiency inclined tube concentrator which increases the sedimentation area of ​​the concentrator and increases the concentration probability. Background technique [0002] At present, the tailing coal water purification of coal preparation plants in my country mainly adopts ordinary thickeners. This thickener mainly has the disadvantages of low sedimentation efficiency, large water inlet kinetic energy, and poor hydraulic conditions in the pool. Influenced by factors such as the density flow, the sedimentation efficiency of the concentrator is very low. In order to speed up the sedimentation of the particles of the slime water, some units adopt the method of adding chemicals, which increases the production cost, resulting in a large pool area, high construction and equipment costs and other shortcomings. In order to change this situation, without increasing the diameter of...

[0002] At present, the tailing coal water purification of coal preparation plants in my country mainly adopts ordinary thickeners. This thickener mainly has the disadvantages of low sedimentation efficiency, large water inlet kinetic energy, and poor hydraulic conditions in the pool. Due to the influence of factors such as the density flow, the sedimentation efficiency of the concentrator is very low. In order to accelerate the sedimentation of the particles of the slime water, some units adopt the method of dosing, which increases the production cost, resulting in large pool area, high construction and equipment costs, etc.
