The utility model belongs to the technical field of powder concentrator, especially involves a powder concentrator is with feeding screening device, including casing, feed inlet, discharge gate and material return, feed inlet is installed in the top of casing, discharge gate is installed in the bottom of casing, material return is installed in the right side of casing, the inside of casing is provided with screening device, and screening device includes vibration mechanism, dismounting mechanism and scattering mechanism, vibration mechanism sets up in the inside of casing, dismounting mechanism sets up in the front and back two sides of casing, scattering mechanism sets up in the inside upper end of casing. The powder concentrator is with feeding screening device, is set up vibration mechanism through the motor one drive shaft and cam rotation, makes the lobe intermittent and the filter screen bottom collision, makes the filter screen vibrate, thereby speeds up the screening of material, is set up scattering mechanism, when material enters the inside of casing, through scattering rod, the agglomerate is scattered, makes it become small granule, thereby facilitates the subsequent screening, improves screening accuracy and quality.

This utility model relates to the field of incinerator slag screening and iron removal technology, specifically an incinerator slag screening and iron removal device, including a screening frame, a mounting plate, an adsorption component, and a screening component. The screening component, through the cooperation of a first chute, a first slider, a second chute, and a second slider, allows the screen to slide within the screening frame. Simultaneously, a reciprocating component on the mounting plate drives the screen to reciprocate, causing the incinerator slag to continuously roll and move on the screen, accelerating the slag screening process. Compared with manual screening of slag one by one, this mechanized screening method greatly improves screening efficiency, enabling the processing of large quantities of incinerator slag in a short time, reducing the time required for screening, and improving overall work efficiency. The adsorption component, installed on the top of the mounting plate, can effectively adsorb iron filings in the incinerator slag. During the screening process of the slag on the screen, the iron filings are attracted by the adsorption component, thereby achieving separation from other slag.

The utility model discloses a kind of quick separation screening machines of earthworm and feed residue, including screening cylinder, the upper portion of the screening cylinder is equipped with injection hopper, the upper surface of the screening cylinder is fixedly installed with variable-frequency motor, the output of the variable-frequency motor is fixedly installed with driving rod, the outer surface of the driving rod is fixedly connected with spiral vane, the spiral vane is inside injection hopper, the bottom end of the driving rod is fixedly installed with distribution rod, the outer surface of the distribution rod is fixedly connected with multiple upper discharge vane The device can realize the continuous injection of earthworm and feed residue mixture inside injection hopper downward by the setting of injection hopper, and then can be automated feeding, in addition, the upper and lower discharge vane on the surface of distribution rod respectively push earthworm and feed residue to discharge through corresponding discharge hole, without manually cleaning earthworm on the upper portion of annular flow guide screen, improve screening speed.

This invention discloses a vibrating screening device for adjustable coal slurry particle size distribution, relating to the field of coal slurry screening technology. It includes: a segmented screen box, the interior of which is divided into at least two vibration zones along the coal slurry flow direction; a screening component disposed within each vibration zone, the screening component being adjustable in terms of particle size; an excitation system disposed on the segmented screen box, the excitation system being used to apply independently adjustable harmonic excitation to each vibration zone; a feed hopper disposed above the feed end of the segmented screen box; and a microbubble generating component disposed inside the feed hopper, injecting microbubbles into the coal slurry. This invention possesses significant advantages such as multi-zone heterogeneous vibration, stepless orifice adjustment for coal slurry particle size, and microbubble anti-clogging and screen cleaning, significantly improving the separation efficiency of coarse and fine particles and meeting the need for refined adjustment of coal slurry particle size distribution under different working conditions.
