Description
Technical field
The present invention is a kind of screening installation that is used for mine, metallurgy, chemical industry, specifically is a kind of drum washer.
Background technology
Existing drum washer mainly is made up of cylindrical shell, transmission device, bracing frame, and cylindrical shell is installed on the bracing frame, drives cylindrical shell by transmission device and rotates, and carries out the cleaning and the screening work of ore.Cylindrical shell can be divided into three sections by function: leading portion is the washup section, and cylindrical shell rotates and makes ore friction mutually in rotation, causes separating of earth and ore, introduces water under high pressure simultaneously, the flush away sludge; The centre is a screening section, and ore is divided into different grades through grating, and little ore is got rid of through grating; Back segment is big ore discharge zone.
Composition according to ore is different with structure, and washup technology can be divided into requirement and obtain big ore and obtain two kinds in sludge.The above-mentioned log washer of current employing all is in order to obtain big ore, and after the sludge of thereupon discharging was gone out with water under high pressure, its mud was reused through the rinse water of circulation post precipitation again.And obtaining the application facet of sludge, and reach the purpose that abandons such as then requiring for the nickel laterite washup gravel separated and rinse well, it is not high to adopt the said equipment to obtain the rate of recovery of sludge, and effect is bad.
Summary of the invention
Defective to above-mentioned prior art existence; For reaching the requirement that to obtain sludge in the washup technology, the present invention is directed to the characteristics of corresponding ore, according to the proterties of washup requirement and its material; To washup efficient and washing pressure, the water yield, washing time; A large amount of research and test have been done in material distribution of stirring collision friction situation, shower water in the reach process etc. in cylinder, and a kind of drum washer is provided, and reach optimum effect; Can make gravel reach the purpose that abandons, and can high efficiencyly as far as possible obtain required sludge greater than certain size.
Drum washer according to the invention comprises cylindrical shell device, transmission device, retaining riding wheel apparatus, riding wheel apparatus, spray equipment and tank, and its middle cylinder body device is provided with four sections tubes: be followed successively by elementary wash drum, elementary sifting barrel, secondary wash drum and regrading tube.Be separately installed with retaining riding wheel apparatus and riding wheel apparatus in said elementary, secondary wash drum lower end; And between elementary wash drum and the elementary sifting barrel, between secondary wash drum and the regrading tube collet is installed all.
Further preferred version is that the total length of elementary sifting barrel and regrading tube accounts for 35% of whole cylindrical shell device length.
Further, in the cylindrical shell installed inside of elementary wash drum the liner plate of light grade is arranged, mutual superposition between per two liner plates adopts bolt to be fixed on the inwall through press strip; The cylindrical shell installed inside of secondary wash drum has the liner plate of heavy grade, and mutual superposition between per two liner plates adopts bolt to be fixed on the inwall through press strip.
Above-mentioned liner plate is the rubber alloy liner plate; Build-up wear-resistant welding rod on the bolt head.
Further, above-mentioned elementary and regrading tube are elementary with the structure regrading tube to be, two ends are provided with the snap ring flange of band groove, and has grating to snap in the groove of two ends snap ring flange and fixing.
Between the snap ring flange, also be fixed with I-steel or shaped steel.
Snap in groove part top at grating and be provided with arc pressuring plate, and arc pressuring plate and grating are fixed on the snap ring flange through dormant bolt.
Wherein grating is that r c square steel is processed.
Drum washer according to the invention can realize obtaining the purpose of sludge, and screening effect is good, and the tool energy-saving effect.
Followingly the present invention is further described according to accompanying drawing and embodiment:

The specific embodiment
The cylindrical shell log washer middle cylinder body device that present embodiment provides comprises punt-pole body device 1, transmission device 2, spray equipment 3 and the tank 4 of Φ 3000 * 10000mm; Cylindrical shell device 1 comprises four sections tubes: the leading portion cylindrical shell is elementary wash drum 5; Be the primary stage of charging with the flushing ore, the rubber alloy liner plate 9 of eclipsed form band light grade is installed, liner plate 9 upper surfaces are added with the press strip 10 of countersunk head screw; Be fixed on the barrel with bolt 11 again; Between itself and elementary sifting barrel 6, be provided with removable collet 12, have a mind to cause the ore trapping phenomena, reach the purpose that prolongs the time of staying of ore in tube.Second section elementary sifting barrel 6 of cylindrical shell is the stage of elementary spoil disposal, is made up of the round snap ring flange 13, I-steel 14 and the grating 15 that have groove, and wherein grating 15 adopts r c square steel to process.On the circumference of the two ends of grating 15, push down with polylith arc pressuring plate 16, with dormant bolt 11 grating 15 is snapped in and is fixed on the snap ring flange 13,11 on bolt is gone up build-up wear-resistant welding rod FB-1, prolongs the service life of bolt with this.Round clasp flange 13 is accomplished fixing grating 15 simultaneously, constitutes sifting barrels with I-steel 14 and is stopped the three kind effects of flushing water to the normal use influence of transmission device.The 3rd section cylindrical shell is secondary wash drum 7, carries out secondary cleaning, and purpose is cleaned for the ore that will in elementary wash phase, fail to clean again.Its inwall is equipped with heavy grade rubber alloy liner plate 9; Install and constitute with wash drum 5 is consistent for the first time; Make ore in the cylindrical shell rotation process, obtain the more violent ability of stirring, strengthen the contact area of ore outer surface and rinse water, between itself and regrading tube 8, removable collet 12 is set once more by heavy grade liner plate 9; Another prolongs the time of staying of ore in cylindrical shell, makes the lump ore time as much as possible rest in the washup section.The 4th section regrading tube 8 structures are with first sifting barrel 6, and its blanking place is provided with protective cover 17.Discharge, handle and collect through sifting barrel through the sludge after cleaning for the second time at last, the gravel after cleaning is got rid of and is abandoned from nozzle with the cylindrical shell device.
In the said process; The total length of two sections sifting barrels is 35% of a cylindrical shell device length; Let the mineral that are rinsed get into behind the cylindrical shell device in 40～50s, with 80% or more-50mm grade material (valuable mineral and earth) separates and falls into subsequent processing row scouring again, and below 20%+50mm gravel and walk obtain more effective flushing in the time of staying more than remaining 140s; Then after the screening of secondary sifting barrel; Terminal what discharge is the gravel that can abandon at the cylindrical shell device, and its mud containing rate (3mm) less than 3%, reaches the requirement to nickel laterite washup technology.Wherein the heavy grade rubber alloy liner plate 9 of secondary wash drum 7 inwalls installation increases 12%-15% than light grade rubber alloy liner plate 9 thickness of elementary wash drum 5 installations.
The abrasion mechanism of wherein considering the washup screening mainly is to tear damage, on square steel, wraps rubber and plastic alloy, the tearing strength>=80KN/m of its test piece, wear loss≤0.2cm
3/ 1.61Km.Can increase substantially the service life of grating like this.
