Description

A kind of gold dust wet washer

The utility model relates to solid material separation machinery field, relates in particular to a kind of extensive panning wet washer.

The disclosed a kind of patent No. of existing gold dust washing appliance such as Chinese patent communique is 90205945 and is called the utility model patent of " a kind of gold dust is eluriated, broken in bulk putting ".This device utilizes the formation of water-gas combined effect and stiffener materials flow to realize the elutriation and broken the loosing of gold dust.Mainly by drum sieve, drive flitch, injector, gas and water separator and high pressure gas-distribution pipe, high pressure sparge pipe etc. and form.Two high-pressure air pipes and a high-pressure water pipe are suspended near the center of drum sieve, two high-pressure air pipes abut against the both sides of high-pressure water pipe with certain included angle, they eject current and air-flow syzygies washing in parallel material surface respectively, thereby the turbulent fluctuation energy that increases current improves elutriation, broken diffusing effect, makes the ore in sand form rate of recovery of drum sieve improve more than 10%.Though reaching, the said structure of this device makes the broken purpose of loosing and cleaning of gravel mine material, volume is big, the assembling transportation is difficult, power consumption is big but obviously exist, and must be limited the size that enters drum sieve material cobble-stone, otherwise can smash the drum sieve wall, influence the treating capacity of device.

At above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of simple and practical, cheap gravel mine wet washer, can carry out extensive mechanization and produce continuously, to improve treating capacity and washing efficiency.

For achieving the above object, the utility model has adopted a kind of gold dust wet washer, the cleaning sparge pipe that it includes frame and fixes at the top, in the fit beneath of cleaning sparge pipe the glazing bar sieve is arranged, the glazing bar sieve is vertically rearranged by glazing bar, the glazing bar spacing is greater than 130 millimeters, compass screen surface chute downwards tilt and with the angle of horizontal plane be 20 °-30 °.Fit beneath at the glazing bar sieve has the loose screening plant of ring hammer, and the glazing bar of the axial dative bar grizzl(e)y of the loose screening plant of ring hammer is vertically perpendicular.Below glazing bar sieve and the loose screening plant of ring hammer exit gravity flow screen is housed, compass screen surface is placed to the groove lopsidedness that connects material of bottom, and with the horizontal plane inclination angle greater than 25 °, screen-aperture is less than 27 millimeters.Bottom at gravity flow screen and the loose screening plant of ring hammer is equipped with the groove that connects material, and the groove that connects material outlet is connected to fixed chute.

Described ring is hammered loose screening plant into shape and is made up of motor, transmission device, bearing block, rotor, ring hammer, counterattack sieve plate, and it is identical with gravity flow screen wherein to strike back the sieve plate screen-aperture.Motor drives rotor by transmission device and the ring hammer arranged on the bearing pin of rotor rotates, and the linear velocity of ring hammer is the 12-18 meter per second, and the ring hammer is hinged around it in the rotor rotation and is suspended on epitrochanterian bearing pin rotation.

From technique scheme as can be seen, because glazing bar sieve of the present utility model, the loose screening plant of ring hammer have replaced the cylinder screening plant, thereby the volume of machine itself is little, big gravel in the gravel mine can be discharged automatically, material after slightly washing can be continuously by loose and further screening, enters chute at last less than the material and the water of certain particle size index.Whole process catchment wash, loose, the screening, improved treating capacity and production efficiency greatly, performance is more superior.

The utility model is further explained and explanation below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the right view of Fig. 1.

Structure situation of the present utility model such as Fig. 1, Fig. 2, shown in Figure 3 are equipped with successively from top to bottom on the frame 1 and clean sparge pipe 2, glazing bar sieve 3, the loose screening plant of ring hammer, the groove 10 that connects material, gravity flow screen 9, chute 11.

Ring of the present utility model is hammered loose screening plant into shape and is made up of motor 4, transmission device 5, bearing block 12, rotor 6, ring hammer 7, counterattack sieve plate 8.

The utility model is when operation, available excavator or loading machine continuously are discharged to the gold dust mineral aggregate on the glazing bar sieve 3, owing to clean the high pressure washing of sparge pipe 2, clean impulsive force the gravity flow screen 9 along glazing bar slip into below of back greater than 130 millimeters gravels, further clean the screening back from a side that is discharged to the groove 10 that connects material by self gravitation and follow-up material.After material after washing and the slit between the successive ground warp glazing bar of water fall into the loose screening chamber of being made up of rotor 6, ring hammer 7, counterattack sieve plate 8, since be subjected to the ring hammer 7 of certain rotating speed impact, roll and loose, material also obtains kinetic energy to rush at counterattack sieve plate 8 at a high speed further loose simultaneously.In addition, in whole process, the storeroom of high-speed motion collide mutually equally also produce loose, the screen-aperture of gravity flow screen 9 and counterattack sieve plate 8 is identical and less than 27 millimeters, material and water less than sieve aperture constantly fall into the following groove 10 that connects material from sieve aperture, greater than the bigger gravel of screen size and hardness through flushing back repeatedly by the gravity flow screen 9 below ring hammer 7 and the outlet of rotor 6 pushing in device, the big gravel that dative bar grizzl(e)y 3 falls after further flushing is sieved is together from a side that is discharged to the groove 10 that connects material, groove 10 outlets that connect material are connected to fixed chute 11, fixed chute 11 is placed at a certain angle, enter the material of fixed chute 11, under the impact of self gravitation and big water gaging, flow to its outlet, because gold and sandstone, the difference in specific gravity of water is very big, particle diameter is big, the sandstone that proportion is little is washed away, less sandstone and goldc grains are trapped in the slide lattice and form heavy sand, in order to further refining processing after collecting.
