Description

Technical Field

[0001] This utility model belongs to the field of mineral screening technology, and in particular relates to an array micro powder screen. Background Technology

[0002] In the field of micronized material screening, traditional equipment mostly adopts single-stage series screening or single-unit screening mode, which has prominent problems of low processing efficiency and limited capacity. For large-volume mineral pretreatment, conventional screening processes often require multiple feedings and step-by-step processing, which is not only cumbersome to operate, but also makes it difficult to ensure the consistency of screening accuracy between different batches. When facing raw materials with a wide particle size distribution, single screen structure is prone to screen hole blockage or fine powder dust, affecting the working environment and screening efficiency. Existing technologies lack efficient coarse and fine separation and parallel processing mechanisms, and cannot realize multi-stage screening simultaneously under continuous feeding conditions, which restricts the dual requirements of processing capacity and screening accuracy in industrial production.

[0003] Therefore, this utility model provides an array micro powder sieve to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide an array micro powder sieve. A rotating shaft is rotatably installed inside the conveyor cylinder of the feeding assembly. A spiral-shaped pushing brush is fixedly installed on the outer wall of the rotating shaft. A screening port is opened on the lower side wall of the conveyor cylinder, and a coarse screen is fixedly installed inside the screening port. A distribution trough is set below the screening port, and a set of screening components are respectively set below a set of discharge pipes at the lower end of the distribution trough. The ore is loaded into the conveyor cylinder, and the rotating shaft is driven by a motor to rotate, causing the pushing brush to push the ore forward. Larger particles flow into the conveyor cylinder and are discharged from one end of the conveyor cylinder, while smaller particles fall from the screen into the distribution trough. The distribution trough divides the ore into various screening components for further screening, achieving multi-level screening of large quantities of ore.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an array micro powder sieve, including a feeding component, an inspection platform, and a set of screening components. The feeding component includes a conveying cylinder and a distribution trough. The conveying cylinder is horizontally arranged, and a rotating shaft is rotatably installed inside the conveying cylinder. A spiral-shaped pusher brush is provided on the outer wall of the rotating shaft, and one side of the pusher brush is attached to the inner wall of the conveying cylinder. One end of the rotating shaft passes through the conveying cylinder and is fixedly connected to the output end of the motor. A screening port is opened through the lower side wall of the conveying cylinder, and a coarse screen is fitted inside the screening port. A feed inlet is provided at one end of the upper side wall of the conveying cylinder, and a slag discharge port is opened through the end face of the conveying cylinder away from the feed inlet. The distribution trough is located below the coarse screen. A set of discharge pipes is fixedly arranged in an array along the length of the distribution trough. Each screening component is located at the lower end of each discharge pipe. The inspection platform is located on both sides of the feeding component.

[0006] A further feature of this invention is that the discharge pipe gradually narrows from top to bottom.

[0007] A further feature of this invention is that the screening assembly includes a vibrating screen frame and a discharge chute. A dust cover is fixedly installed at the upper end of the vibrating screen frame, and a feed pipe is fixedly installed at one end of the upper surface of the dust cover. The axis of the feed pipe forms an angle with the length direction of the dust cover. The feed pipe is sleeved on the outside of the discharge pipe. A screen is fixedly installed inside the vibrating screen frame. The discharge chute is fixedly installed on the lower surface of the vibrating screen frame. The end face of the discharge chute and the dust cover away from the feed pipe is open.

[0008] A further feature of this invention is that two receiving ears are fixedly provided on the outer side walls of both sides of the dust cover, and two receiving beams are provided on both sides of a set of dust covers. A spring is fixedly connected to the lower end face of the receiving ear, and the lower ends of the springs on both sides are fixedly connected to the upper end face of the receiving beams on both sides. The receiving beams on both sides are fixedly connected to the inspection platforms on both sides.

[0009] A further feature of this invention is that a vibration motor is provided at the upper end of each dust cover.

[0010] A further feature of this invention is that a flexible constricting sleeve is fixedly sleeved on the outside of the feed pipe, and the upper end of the flexible constricting sleeve is fixedly sleeved on the outside of the discharge pipe.

[0011] A further feature of this invention is that the inspection platform includes two scaffolds and a connecting ladder. The two scaffolds are respectively set on both sides of the material feeding assembly, and the connecting ladder connects one end of the two scaffolds.

[0012] This utility model has the following beneficial effects: This invention achieves continuous separation of large particles and preliminary screening of fine particles by adopting a feeding structure that combines a spiral pushing brush with a coarse screen. Combined with the array-type diversion design of the distribution trough, the material can be simultaneously distributed to multiple parallel-working screening components, which greatly improves the processing efficiency per unit time and effectively solves the problem of insufficient capacity of traditional single-stage screening.

[0013] This invention utilizes an integrated design of arrayed independent screening components and dust covers to achieve multi-stage synchronous screening while creating a closed working environment. This not only avoids pollution of the working environment by fine dust, but also prevents vibration interference and material mixing through the isolated operation of each screening unit, significantly improving screening accuracy and stability.
