An effective dosing device for a thickener

Abstract

This utility model discloses an effective dosing device for a thickener, including a U-shaped mounting frame. A rotating box is connected to the middle of the inner cavity of the U-shaped mounting frame. A stirring tank is fixedly installed inside the rotating box. A first servo motor is fixedly connected to the left side of the U-shaped mounting frame. The output shaft of the first servo motor extends into the U-shaped mounting frame and is fixedly connected to the middle of the left side of the rotating box. This avoids dead angles in the stirring and cutting process, causing the rotating box to be inverted, and then rotating the sediment at the bottom of the agent to the top. This effectively avoids sedimentation during agent storage. It eliminates the need to add the agent to the thickener after it has been stirred evenly. The agent can be stored in the storage tank for a long time and is ready for use, greatly improving its practicality. It can effectively detect whether the concentration at the top and bottom of the liquid is consistent to determine whether sedimentation has occurred, further ensuring the uniformity of the liquid output.

Description

Technical Field

[0001] This utility model relates to the field of thickener dosing technology, specifically to an effective dosing device for thickeners. Background Technology

[0002] A thickener is a solid-liquid separation device based on gravity settling. It is typically a shallow cylindrical tank with a conical bottom, constructed using concrete, wood, or welded metal plates as structural materials. It can concentrate slurry with a solids content of 10%–20% into an underflow slurry with a solids content of 45%–55% through gravity settling. The thickened underflow slurry is then discharged from the underflow outlet at the bottom of the thickener by the action of a slowly rotating rake installed inside the thickener. The normal operation of the thickener relies on the cooperation of an efficient chemical dosing system.

[0003] In existing technologies, reagents used in general dosing devices tend to precipitate after long-term storage. This internal sedimentation leads to uneven reagent distribution. Consequently, if the thickener dosing device cannot guarantee the uniformity of dosing, it will result in increased production costs and low work efficiency. Application No. 202123227896.1 discloses a high-uniformity dosing device for copper ore thickeners, including a shell, a feeding pipe fixedly connected to the top of the shell, and a discharge pipe fixedly connected to one side of the bottom of the feeding pipe. Two round rods are arranged in the upper part of the inner cavity of the shell along the horizontal direction of the shell. The above device must perform dosing operations in a timely manner after crushing. However, when waiting for dosing operations for a long time, particulate impurities in the reagent will still precipitate, and the uniformity of dosing cannot be guaranteed.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
