Description

Technical Field

[0001] The utility model relates to the technical field of pulp pretreatment, in particular to a device for pulp pretreatment in the flotation process of lead-zinc ore. Background Technique

[0002] Flotation, namely foam flotation, is a process of separating minerals from pulp by means of the buoyancy of bubbles based on the differences in the surface properties of various minerals. Its separation process mainly depends on the differences in the physicochemical properties of the material surface. In a stirred suspension, under the action of different agents, the material forms a hydrophilic or hydrophobic surface. The hydrophobic material effectively contacts the rising bubbles and adheres to the bubbles to rise and form a foam layer, thereby achieving separation. Flotation is the most important separation method, and it can process the vast majority of minerals. Flotation is usually divided into positive flotation and reverse flotation according to the attribution of the products.

[0003] In order to improve the flotation effect, it is necessary to pre-treat the pulp to improve the subsequent flotation effect.

[0004] At present, during the pretreatment of pulp, it is necessary to add agents to the pulp. During the process of adding agents, most of them are directly poured, resulting in the agents falling in piles and unable to be added evenly, affecting the pretreatment of pulp. Therefore, it is necessary to propose a device for pulp pretreatment in the flotation process of lead-zinc ore to solve the above-mentioned problems. Content of the Utility Model

A quantitative chamber fixedly connected to the bracket is arranged above the feeding cylinder. Weighing modules are installed at the four corners of the upper end surface of the bracket and the lower end surface of the quantitative chamber.

[0008] In order to disperse and drop the reagents in the feeding barrel, as a preferred device for pretreating slurry in the lead-zinc ore flotation process of the utility model, the lower end surface of the feeding barrel is penetrated with mesh holes.

[0009] In order to stir the slurry in the device body, as a preferred device for slurry pretreatment during lead-zinc ore flotation of the utility model, a motor is installed on the lower end surface of the device body, and the output end of the motor passes through and extends into the interior of the device body and is fixedly connected to a stirring rod.

[0020] As a technical optimization scheme of the present utility model, the upper end surface of the device body 1 is fixedly connected with a support. Above the feeding cylinder 302, there is a quantitative chamber 4 fixedly connected to the support. At the four corners of the upper end surface of the support and the lower end surface of the quantitative chamber 4, there are weighing modules 403 installed.
