Abstract

The invention relates to the technical field of ore pulp filtering, in particular to a charcoal-isolated drum sieve. The charcoal-isolated drum sieve comprises a drum sieve screen and a drum frame supporting the drum sieve screen. The inner wall of the left end of the drum frame is connected with a pipe, a bearing penetrates into the pipe, the bearing, the pipe and an axis of the drum frame are superposed, one ends of the bearing and the pipe extend out of an adsorption groove, and a sealing device is arranged at a contact position of the pipe and the adsorption groove. Since the drum sieve of the charcoal-isolated drum sieve can rotate, open area of the ore pulp on a charcoal-isolated sieve is improved by three times as compared with that of an original fixed type drum sieve, utilization of the sieve screen is up to 100%, the service life of the sieve screen is prolonged by one time as compared with that of the original fixed type drum sieve, and the sieve screen can be replaced flexibly and conveniently. Further, activated charcoals blocking screen meshes can be scoured by the ore pulp along with rotation of the drum sieve, and the problem of blockage of the sieve screen is solved. By the aid of the sealing device, loss of gold between grooves is avoided and economic loss is reduced.

Description

A kind of every the charcoal drum sieve

Technical field

The present invention relates to the slurry filtration technical field, relate in particular to a kind of every the charcoal drum sieve.

Background technology

All sliming cyanidation charcoal slurry selects in the golden production technology, need the slurry filtration in the charcoal absorption groove is discharged, but because the sealing of existing carbon isolated sieve is not strong, appearance absorption has the active carbon of gold along with the ore pulp after filtering flows out outside the adsorption tank, has caused loss economically.And existing carbon isolated sieve is fixed drum sieve, fixed drum sieve is feasible in little, the production that the ore clay content is little of day milling capacity, but in processing the relatively large production technology of 3000 tons and above clay content day, because of the screen cloth contact area little, screen cloth occurring is stopped up by active carbon or silt, crossing slurry does not freely cause excessive groove, emits the phenomenon such as groove, cause the active carbon charcoal Density Distribution in each adsorption tank uneven, greatly reduce the golden capacity that carries of active carbon, finally cause the tail washings grade to be run high, recovery rate in ore-dressing reduces, and affects normally carrying out of mineral processing production.

Summary of the invention

The purpose of this invention is to provide a kind of good airproof performance, high efficiency every the charcoal drum sieve.

For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:

A kind of every the charcoal drum sieve, comprise the cylinder frame of cylinder screen and mesh support screen, cylinder frame left end inwall is connected with a pipe, the logical bearing that is provided with in the pipe, the dead in line of bearing, pipe and cylinder frame, an end of bearing and pipe stretches out adsorption tank, and pipe is provided with sealing device with the contact position of adsorption tank.

Described a kind of every the charcoal drum sieve, described sealing device is two semicircular bearing bushs, is screwed in the adsorption tank cell body outside.The active carbon in the adsorption tank that is arranged so that of two semicircular bearing bushs can not flow out from pipe and the contact position of adsorption tank, has avoided the loss of gold between groove and the groove, has reduced economic loss.

Described a kind of every the charcoal drum sieve, the outer body of adsorption tank links to each other with the clutch shaft bearing seat by bearing shell.

Described a kind of every the charcoal drum sieve, described bearing left end links to each other with the second bearing block, and is connected with sprocket wheel.

Described a kind of every the charcoal drum sieve, described bearing is connected in the round steel of inside pipe wall welding.Bearing one end is arranged on the second bearing block, and its part in pipe is connected with the round steel of inside pipe wall welding, and when sprocket wheel drove the bearing rotation, pipe also drove drum sieve thereupon and rotates.The area of passage of ore pulp has improved 3 times than original fixed drum sieve on the carbon isolated sieve, and under the rotation of drum sieve, the screen cloth utilization rate reaches 100%, and screen cloth has prolonged 1 times service life than originally, and is flexible when changing screen cloth; And the active carbon of obstruction mesh, can be washed away by ore pulp along with the rotation of drum sieve, solved the problem that screen cloth stops up.

Described a kind of every the charcoal drum sieve, have aperture on the body of the pipe of cylinder frame inside.Ore pulp enters in the pipe by aperture after by screen cloth, discharges adsorption tank by pipe.

Described a kind of every the charcoal drum sieve, described pipe is stainless steel tube.

Provided by the invention every the charcoal drum sieve, because its drum sieve can rotate, so that the area of passage of ore pulp has improved 3 times than original fixed drum sieve on the carbon isolated sieve, under the rotation of drum sieve, the screen cloth utilization rate reaches 100%, screen cloth has prolonged 1 times service life than originally, flexible when changing screen cloth; And the active carbon of obstruction mesh, can be washed away by ore pulp along with the rotation of drum sieve, solved the problem that screen cloth stops up.And the design of sealing device, avoided the loss of gold between groove and the groove, reduced economic loss.

Description of drawings

Fig. 1 is structural representation of the present invention.

The specific embodiment

As shown in Figure 1, the second bearing block 2, sprocket wheel 3, cylinder screen 5 and cylinder frame 11 are arranged in the adsorption tank 1, cylinder frame 11 left end inwalls are connected with a steel pipe 4, be connected with a bearing 6 in the steel pipe 4, the dead in line of bearing 6, steel pipe 4 and drum sieve rack 11, bearing 6 is connected in the first round steel 7, second round steel 8 of steel pipe 4 inwalls welding, and an end of bearing 6 and steel pipe 4 stretches out outside the adsorption tank 1, and steel pipe 4 is provided with two semicircular bearing bushs 10 with the contact position of adsorption tank 1.Bearing 6 one ends link to each other with the second bearing block 2 with sprocket wheel 3.The end of steel pipe 4 outside adsorption tank 1 links to each other with clutch shaft bearing seat 9 by two semicircular bearing bushs 10.

Sprocket wheel 3 band dynamic bearings 6 rotate, and drive 5 rotations of cylinder frame with the steel pipe 4 that bearing 6 is connected by the first round steel 7, the second round steel 8 thereupon, and ore pulp enters in the steel pipe 4 through the aperture on steel pipe 4 bodys by behind the cylinder screen 5, flows out outside the adsorption tank.Active carbon is filtered outside cylinder screen 5, and the active carbon of clogging cylinder screen 5 can be along with the rotation of cylinder frame 5, and the ore pulp that is adsorbed in the groove 1 washes away.
