Description

Technical Field

[0001] The utility model relates to the field of ore dressing, in particular to a device for quantitatively adding ore dressing agents. Background Art

[0002] Flotation refers to the use of surfactants - foaming agents that can generate a large number of bubbles. When air is introduced into water or air enters the water due to the agitation of water, the hydrophobic ends of the surfactants are oriented towards the air side of the bubbles at the gas - liquid interface, and the hydrophilic ends remain in the solution, forming bubbles; another surfactant that plays a trapping role (generally cationic surfactants, including fatty amines) is adsorbed on the surface of solid ore powder. This adsorption has a certain selectivity depending on the properties of the minerals. Its basic principle is to utilize the lattice defects on the crystal surface, and the outward hydrophobic ends partially insert into the bubbles. In this way, during the flotation process, the bubbles may carry away the designated ore powder to achieve the purpose of ore dressing. However, the existing ore dressing devices have poor flotation quality because they cannot accurately control the addition amount of ore dressing agents during ore dressing, and thus need to be improved urgently. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a device for quantitatively adding ore dressing agents, which is used to solve the problem that the existing device for quantitatively adding ore dressing agents cannot accurately control the addition amount of ore dressing agents.

[0004] To solve the above problems, the utility model provides a device for quantitatively adding ore dressing agents, including an ore dressing box and a movable hopper. A notch is opened at the top of the ore dressing box, and the movable hopper can move up and down in the notch. A first compression spring is fixedly arranged between the ore dressing box and the movable hopper. A plurality of liquid discharge holes are opened at the bottom wall of the movable hopper. An insertion needle assembly for blocking the liquid discharge holes is fixedly arranged on the ore dressing box. When the movable hopper descends to a predetermined height, the insertion needle assembly is separated from the liquid discharge holes, and the liquid discharge holes are in an open state.

[0005] The device for quantitatively adding ore dressing agents provided by the utility model further has the following technical features:

[0006] Further, a liquid outlet pipe is arranged below the side wall of the ore dressing box.

[0007] Further, the insertion needle assembly includes a central blocking rod, a plurality of branch blocking rods symmetrically fixed on both sides of the central blocking rod, and a positioning frame fixedly connected to the central blocking rod for limiting the position of the movable hopper.

[0008] Further, the positioning frame includes a cross bar fixedly connected to the "L"-shaped plate and the central plugging rod. A locking rod assembly is slidably provided on the "L"-shaped plate. The locking rod assembly includes a locking rod slidably connected to the "L"-shaped plate and a second compression spring sleeved on the locking rod. Grooves for cooperating with the locking rod are symmetrically formed on both sides of the movable hopper.

[0009] Further, one end of the locking rod close to the groove is hemispherical, and a handle is fixedly provided at the end of the locking rod away from the groove.

[0010] Further, the central plugging rod and the branch plugging rods are made of stainless steel.

[0011] The utility model has the following beneficial effects: The liquid discharge holes on the movable hopper are in a plugged state. As the staff adds beneficiation reagents to the movable hopper, the movable hopper gradually descends. When the movable hopper descends to a preset position, the liquid discharge holes are completely separated from the needle insertion assembly, and the liquid addition stops. At this time, the liquid discharge holes are all automatically opened, and a quantitative amount of beneficiation reagents automatically flow into the beneficiation box through the liquid discharge holes for flotation operation. The structure is simple and the design is ingenious. Description of the Drawings
