Description

Technical Field

[0001] This invention relates to the field of slurry distribution device technology, specifically a multi-channel slurry distributor. Background Technology

[0002] Vibrating screens operate by utilizing the reciprocating rotary vibration generated by a vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The combined effect of these two factors results in a complex rotary vibration of the screen surface. Currently, vibrating screens are widely used in the mineral processing industry. Among them, due to their small footprint and high degree of structural integration, stacked screens have become the most widely used screens since the beginning of this century. As a multi-layer parallel self-synchronizing inertial linear vibrating screen for wet separation and classification of fine-grained materials, it is used for controlled classification in the beneficiation of iron ore, rare earth ore, tin ore, and lithium feldspar. The structural feature of the stacked screen is that three to five screen boxes are connected in parallel to form a screen box group. Each screen box is fixedly connected to a support frame to form a screen frame module. The screen frame module is mounted on an outer support by springs. The outer support is mounted on the ground. Two vibrating motors self-synchronize to drive the screen frame module to vibrate. All screen surfaces are parallel and tilted downwards at a fixed angle. The slurry distributor is used to feed the material to each screen box independently. The screen boxes are equipped with screens. The material on the screen of each screen box is collected and discharged in a centralized manner, and the material undersize of each screen box is collected and discharged in a centralized manner.

[0003] Currently, many slurry distributors used in mineral processing plants have various defects in structural design and functional layout, resulting in uneven slurry distribution and affecting subsequent slurry processing. How to make slurry distributors structurally sound and capable of uniformly distributing slurry is a crucial problem that every mineral processing enterprise needs to solve. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-channel slurry distributor, comprising: a secondary energy dissipation tank, an inverted conical feed inlet, a primary energy dissipation tank, a conical porous energy dissipation hood, and a discharge pipe. Both the secondary energy dissipation tank and the primary energy dissipation tank are cylindrical structures, and the primary energy dissipation tank is fitted into the middle of the inner cavity of the secondary energy dissipation tank. An annular sealing plate is connected between the bottom end of the primary energy dissipation tank and the bottom end of the secondary energy dissipation tank, and multiple discharge holes are evenly opened along the annular edge of the annular sealing plate.

[0008] The outer edge of the bottom of the cone-shaped porous energy dissipation hood is fixedly connected to the inner wall of the first-stage energy dissipation groove near the bottom.

[0009] The top of the primary energy dissipation tank is equipped with an overflow structure for uniform overflow of slurry.

[0010] Preferably, the top of the primary energy dissipation tank is provided with an annular wave-shaped overflow plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The slurry distributor of the present invention has a simple structure, reduces the space occupied by the equipment, and thus meets the usage requirements of different working conditions.

[0021] 2. The slurry distributor of the present invention not only meets the material feeding requirements from different directions by feeding from the bottom, but also reduces the total installation height of the equipment compared with feeding from the top, which can meet some installation conditions with limited height.

[0022] 3. The slurry distributor of the present invention adopts bottom center feeding, inverted cone-shaped feeding port energy dissipation, cone-shaped multi-hole energy dissipation hood for uniform flow and pressure reduction energy dissipation, uninterrupted annular secondary slurry storage tank for uniform mixing, and uniform distribution of material through evenly distributed discharge pipes. These technologies uniformly distribute the slurry to multiple distribution pipes, which is beneficial to the uniform screening of each layer of the multi-layer high-frequency screen assembly in the next step.
