Problems solved by technology

As a relatively advanced coal slurry pretreatment device in the field, the flotation agent droplets are an order of magnitude smaller than the emulsified and dispersed droplets, and the dispersion effect is better; The dispersing effect of the medicine is achieved by the rotation of the fogging disc, which often requires a closed box to form a closed space to avoid the meaningless drift of the mist medicine, but the formation of the closed environment often causes problems such as fogging The working environment of the disc is poor, so it is easy to send product failures, it is impossible to realize the intuitive observation of the slurry mixing process, and it is difficult to find out the faults in time, which brings troubles to the on-site operation and maintenance work; in addition, the high-speed rotating fogging disc, The requirements for the speed of the drive motor are too high, that is, a secondary motor with a speed of up to 3000 rpm must be used to ensure its working performance, which poses severe challenges to the actual assembly, purchase and maintenance costs.

Embodiment Construction

[0046] For ease of understanding, combined here Figure 1-5 , the specific embodiments of the present invention are further described as follows:

[0047] 1.1 Introduction of main components

[0048] (1) Mixing box

[0049] The design of the mixing box 20 is to fully consider the uniform feeding of the incoming pulp, so that each part of the pulp and the medicament have the same contact mixing probability.

[0050] The mixing box 20 can be cylindrical or hexahedral, and of course also can be other shapes, such as Figure 4 Shown is the cylindrical mixing box body. And as Figure 4-5 As shown, the upper box wall of the mixing box 20 is fixed with a slurry feeding tank 70 . Dilution water inlets are arranged on both sides of the slurry feeding tank 70, which is beneficial to quickly and evenly adjust the slurry concentration. In order to ensure uniform overflow all around, a cover plate 71 is provided above the pulp inlet tank 70, and the cover plate 71 is provided with a ...

Abstract

The invention relates to the field of coal slurry pre-treatment, and in particular relates to a jet-driven medicament disperse system and pulp mixing modification equipment applying the same. The jet-driven medicament disperse system comprises a jet spray nozzle and a liquid flow pipe, wherein the jet spray nozzle comprises an outer pipe body, the outer pipe body is internally and coaxially provided with a rotating shaft in a sleeving manner, and a driving impeller and a driven impeller are coaxially arranged on the rotating shaft; the liquid discharging direction of a pass pipeline, connected with the outer pipe body, of the liquid flow pipe is located in the tangential direction of the driving impeller, and a pipe chamber of the pass pipeline is provided with a pipeline mixer for preliminarily mixing ore pulp and a medicament. The system can effectively realize the uniform mixing feeding requirements of the medicament and the ore pulp in a controllable manner. The pulp mixing modification equipment comprises a mixing box and a graded mixing system, the top of the mixing box is provided with a medicament atomization dispersing system and the bottom is provided with the jet spray nozzle, a liquid outlet of the mixing box is arranged in a way different from the mounting position of the outer pipe body. The equipment is especially suitable for the pulp mixing modification requirement of fine-particle coal difficult to float, the working efficiency of the equipment is high and the pre-treatment process is quick and convenient.

Description

technical field [0001] The invention relates to the field of coal slurry pretreatment, in particular to a jet-driven chemical dispersing system used for slurry conditioning and upgrading of high-ash refractory fine-grained coal slime and slurry conditioning and upgrading equipment using the system. Background technique [0002] Because the buoyancy of coal slime in our country is generally poor, coal slurry pretreatment is an indispensable link in the flotation coal preparation process, and it is a prerequisite for the flotation machine to obtain good technical and economic indicators. The necessity of coal slurry pretreatment mainly includes the following four points: 1) Fully disperse the flotation agent (non-polar oil collector and foaming agent), the flotation agent of coal slime is insoluble or slightly soluble in water, Only by fully dispersing it into a large number of tiny droplets can it be uniformly mixed into the coal slurry; 2) Mix the dispersed flotation agent w...
