Description

Automatic sediment device of arranging of depositing reservoir

Technical Field

The utility model belongs to the technical field of titanium dioxide production, and particularly relates to an automatic slag discharging device of a clarification tank.

Background

In the production of titanium dioxide by a sulfuric acid method, acidolysis clarification is one of the most important and critical processes, firstly, ground mineral powder (with the fineness of 5-10%) and concentrated sulfuric acid with the concentration of 93% are mixed to generate chemical reaction, after a solid-phase substance is formed, a certain amount of water is added to dissolve a solid phase to obtain a titanyl sulfate solution, the titanyl sulfate solution dissolved by adding water contains a large amount of slurry, impurities and unreacted mineral powder, so that solid-liquid separation is required by natural sedimentation, the titanyl sulfate solution is naturally settled in a settling tank after being mixed with a flocculating agent through a mixing tank, after 6 hours, a supernatant with the depth of 1.5m is taken to carry out suction filtration sample measurement, and when the solid content of filter paper is below 0.3mg/l, the supernatant is removed by a pump through a floater with a fixed height. After each sedimentation tank is used for 5-6 batches, the bottom slurry can be precipitated more, the slurry is cleaned completely at one time according to the actual condition of the slurry, the slurry is cleaned manually with small-scale water, a large amount of filtrate after being cleaned needs plate and frame filter pressing, the production efficiency and continuity are greatly reduced, water resources and electric power resources are consumed, and the production cost is increased.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

Example 1: see fig. 1, an automatic sediment device of arranging of depositing pond, its characterized in that: the lower part of the clarification tank 1 is a cone 2, the bottom of the cone 2 is provided with a pneumatic valve A3, and the pneumatic valve A3 is connected to a mud tank 8 through a mud pipe 9; a supernatant fluid discharge pipe 10 is arranged in the middle of the vertebral body 2, a pneumatic valve B11 is arranged on the supernatant fluid discharge pipe 10, and the supernatant fluid discharge pipe is connected with a front pipe filtration process through a discharge pump 12; a material beating floater 5 is arranged in the clarification tank 1, a hose 4 is fixed on the material beating floater 5 by a holding clamp, and a pipe orifice at the upper end of the hose 4 faces downwards and extends into the liquid level; the lower end orifice of the hose 4 is connected with the orifice of the upper clear liquid discharge pipe 10.

And a submerged pump 7 is arranged in the mud pit 8, and a mud discharging pipe of the submerged pump 7 is connected with a black slag plate frame filter pressing system.

The beating floaters 5 are connected by a fixing rope 6, and the other end of the fixing rope 6 is fixed on the wall of the clarification tank 1.
