Abstract
The utility model relates to a medium drainage screen water spray device for coal dressing, and aims to enhance medium drainage and desliming effects of a medium drainage screen through the medium drainage screen water spray device and further improve the medium drainage efficiency of the medium drainage screen. The technical scheme provided by the utility model is that: one end of a water supply pipe is fixedly connected with a side wall of a main pipe; the water supply pipe is communicated with the main pipe; the side wall of the main pipe is fixedly connected with one end of each of three split pipes; the main pipe is communicated with the three split pipes; the three split pipes are horizontally arranged in parallel; and two opposite side faces of the three split pipes are provided with a row of spray nozzles communicated with the split pipes in the length direction of the split pipes. The medium drainage screen water spray device is used for coal dressing of dense medium coal dressing plants, and the medium drainage and desliming effects of the medium drainage screen can be enhanced.
Description
Technical field
The utility model relates to a kind of coal separation and uses water injector.
Background technology
In heavy-media coal preparation process, product de-media is an important link, and the capital equipment of de-mediated is exactly a sculping screen.The quality of sculping screen de-mediated effect directly affects coal preparation plant's washing cost and product quality.At present, the sculping screen that mostly adopt in the sink float coal works is the water injector of the double mode of single tube, and the water discharge pattern of this device to the flushing action of coal inadequately by force and thorough inadequately; The contact area of water and particle is less relatively, causes coal surface dielectric and thin mud flushing unclean easily, and then directly influences the de-mediated product quality; Increase dielectric loss; Reduced de-mediated efficient, when particularly coal granularmetric composition is thin partially, influenced particularly remarkable.
Summary of the invention
The purpose of the utility model provides a kind of coal separation and uses the sculping screen water injector, can strengthen the de-mediated desliming effect of sculping screen through this sculping screen water injector, further improves the de-mediated efficient of sculping screen.
The utility model for the technical scheme that realizes above-mentioned purpose is:
The sculping screen water injector is used in a kind of coal separation; Comprise the feed pipe and the person in charge, an end of feed pipe is fixedly connected with the person in charge's sidewall, and feed pipe communicates with the person in charge; The sidewall of being responsible for is fixedly connected with an end of three isocons; Be responsible for to communicate with three isocons, three isocon levels and being set up in parallel, the length direction of upper edge, two sides facing each other isocon is respectively installed the shower nozzle that a row communicates with isocon in three isocons.
Every row's shower nozzle is made up of a plurality of shower nozzles, and a plurality of shower nozzles are evenly arranged along the length direction of isocon.
The effect of the utility model: two sections (constituting one section by adjacent two isocons in three isocons) three pipes (three isocons), four row's water sprays (four row's shower nozzles are realized) that the utility model mainly relies on this device to form; Two sections reverse water sprays (quantity of isocon upper nozzle and the size of spout are specifically confirmed according to different atures of coal); Thereby increased the contact area of coal particles and water greatly, strengthened coal particles de-mediated desliming effect, and the medium rate of recovery is improved significantly; Reduced the input of production cost; Avoided the sculping screen sieve to go up coal particles and had the not thoroughly generation of phenomenon of de-mediated desliming, reduced the medium amount on the product that sticks to, reduced dielectric loss than limits; Improve the de-mediated desliming efficient and the product quality of sculping screen, reduced dense-medium separation washing cost greatly.
Description of drawings
Fig. 1 be the utility model a kind of coal separation with the sculping screen water injector overlook the sectional structure sketch map, direction shown in the horizontal arrow is that current get into the feed pipe direction among the figure, direction is a water spraying direction shown in the vertical arrow in shower nozzle place.
Among the figure, feed pipe 1, the person in charge 2, isocon 3, shower nozzle 4.
The specific embodiment
Like Fig. 1, the sculping screen water injector is used in a kind of coal separation, comprises feed pipe 1 and is responsible for 2; One end of feed pipe 1 is fixedly connected with the sidewall of being responsible for 2; Feed pipe 1 be responsible for 2 and communicate, be responsible for 2 sidewall and be fixedly connected with an end of three isocons 3, the person in charge 2 communicates with three isocons 3; The length direction of upper edge, two sides facing each other isocon 3 is respectively installed the shower nozzle that a row communicates with isocon 3 in three isocon 3 levels and being set up in parallel, three isocons 3; Every row's shower nozzle is made up of a plurality of shower nozzles 4, and a plurality of shower nozzles 4 are evenly arranged along the length direction of isocon 3; Three isocons 3 in this embodiment are straight tube; Three preferably equidistant levels of isocon 3 are set up in parallel.
During work; Current feed feed pipe 1 through the slag stock pump with certain pressure; Be diverted to three isocons 3 (straight tube) through being responsible for 2,, on compass screen surface, form two section three pipe, four row's water sprays again by 4 ejections of a plurality of shower nozzles on three isocons 3; Every section shower nozzle by the reverse water spray of two rows is formed, and forms the flushing action to coal particles.
Claims (2)
1. the sculping screen water injector is used in a coal separation; Comprise feed pipe (1) and be responsible for (2); One end of feed pipe (1) is fixedly connected with the person in charge's (2) sidewall; Feed pipe (1) communicates with being responsible for (2), it is characterized in that: the sidewall of being responsible for (2) is fixedly connected with an end of three isocons (3), is responsible for (2) and communicates with three isocons (3); Three isocon (3) levels and being set up in parallel, the length direction of two sides facing each other upper edge isocon (3) is respectively installed the shower nozzle that a row communicates with isocon (3) in three isocons (3).
2. the sculping screen water injector is used in a kind of coal separation as claimed in claim 1, it is characterized in that: every row's shower nozzle is made up of a plurality of shower nozzles (4), and a plurality of shower nozzles (4) are evenly arranged along the length direction of isocon (3).
