Abstract

The utility model discloses a circular vibrating screen, which comprises a stand, wherein the stand is fixedly provided with a support spring group; the support spring group is provided with a screen box; the screen box can be provided with at least two layers of inclined screen in a removable way, the screen hole of the upper layer of screen is larger than the screen hole of the lower layer of screen, and the lower end of each screen is correspondingly provided with a discharge hole; a main shaft is arranged under the screen box, and the two sides of the main shaft are provided with vibration exciters, and are in power connection with a power plant. In the utility model, a single-shaft vibration and seat-type support is adopted, the screen box generates vibration with a circular trace under the action of the vibration exciter to make fine fraction pass through the bed of material and is screened through the screen holes, the particles blocked in the screen holes are vibrated out of the screen, through the screening of screens with different bore diameters layer by layer, material meeting the standard can be obtained.

Description

Circular shale shaker

Technical field

The utility model relates to a kind of sieving machine.

Background technology

Now no matter be underground or coal that field of opencast mining is exploited out or ore; or through broken material; or the needed raw material of other industrial products; some granular industrial products; mostly be that before unprocessed the form that particle with all size inequality mixes exists, some material even contain a lot of moisture, clay or other useful or useless media.In order to reach spent material and quality (granularity, the composition) requirement of satisfying product, in ore dressing plant, coal washery, carpolite factory or other industrial departments, material is before using or further handling, usually need to be divided into the close several ranks of granularity or dewater, desliming, de-mediated, be to need simultaneously sometimes.In order to finish above-mentioned work,, need have the sieving machine of advantages such as screening efficiency height, long service life, maintenance, repair convenience, reasonable price according to the market demand.

The utility model content

Technical problem to be solved in the utility model provides the circular shale shaker that a kind of exciting force is strong, screening efficiency is high.

For solving the problems of the technologies described above, the technical solution of the utility model is: circular shale shaker, comprise support, be installed with the support spring group on the described support, on the described support spring group screen box is installed, the screen cloth of two-layer at least inclination detachably is installed on the described screen box, the sieve aperture of upper strata screen cloth is bigger than the sieve aperture of lower screen, the low side correspondence of each described screen cloth is provided with discharging opening, under the described screen box main shaft is installed, described main shaft both sides are equipped with vibrator, and described main shaft power is connected with power set.

As a kind of preferred version, the tilt adjustable of described screen box.

As a kind of improvement, described vibrator is the heavy eccentric disc of adjustable eccentric.

As further improvement, described power set are motor, are connected with shaft coupling on the described motor.

As further improvement, described shaft coupling is a coupling with rubber type element.

Owing to adopted technique scheme, circular shale shaker, comprise support, be installed with the support spring group on the described support, on the described support spring group screen box is installed, the screen cloth of two-layer at least inclination detachably is installed on the described screen box, the sieve aperture of upper strata screen cloth is bigger than the sieve aperture of lower screen, and the low side correspondence of each described screen cloth is provided with discharging opening, under the described screen box main shaft is installed, described main shaft both sides are equipped with vibrator, and described main shaft power is connected with power set; The utility model adopts be single shaft vibration, the supporting of seat formula and screen box under the effect of vibrator, produced the vibration of circular trace; Because the vibration of vibrator makes material bed loose on the screen cloth and leaves screen cloth and throw, make fine fraction can see through that the bed of material falls and by under the mesh screen, and the particle that will be stuck in the sieve aperture shakes, and by different aperture sieve stratum reticulare layers screening, we have just obtained satisfactory material.

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

The specific embodiment

Below in conjunction with the specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

As Fig. 1, Fig. 2 and shown in Figure 3, circular shale shaker, comprise support 8, be installed with support spring group 1 on the described support 8, on the described support spring group 1 screen box 2 is installed, the screen cloth of two-layer at least inclination detachably is installed on the described screen box 2, the sieve aperture of upper strata screen cloth is bigger than the sieve aperture of lower screen, and the low side correspondence of each described screen cloth is provided with discharging opening 9, and described screen box is equipped with main shaft 62 times, described main shaft 6 both sides are equipped with vibrator 7, and described main shaft 6 power are connected with power set.

The tilt adjustable of described screen box 2; Can regulate the inclination angle of described screen box as required.

Described vibrator 7 is the heavy eccentric disc of adjustable eccentric; Described exciting source replaces traditional eccentric shaft by adjustable eccentric disc, and weight is greatly alleviated; Eccentric disc is arranged on described screen box 2 both sides, distributes rationally, and vibrations efficient height can obtain different amplitudes by changing the eccentric weight of eccentric disc.

Described power set are motor 4, are connected with shaft coupling on the described motor 4; Described shaft coupling is a coupling with rubber type element 5; Adopt coupling with rubber type element 5 to transmit moment of torsion, effectively solve described vibrator 7 vibrations and motor 4 non-vibrating articulation issues.

Present embodiment can reach the effect that a machine can sieve multiple granularity material simultaneously according to the number of plies of producing needs increase and decrease screen cloth.Also can pass through the appropriate change sifting-bed inclination, increase the movement velocity of material, thereby can improve the treating capacity of sieve along screen cloth.

What present embodiment adopted is single shaft vibration, the supporting of seat formula, present embodiment must start when zero load, treat to begin feed after it operates steadily, material is uniform to screen surface along chute, the direction of vibrator feeding stream begins revolution, at this moment because the vibration of vibrator is constantly overturn with loose material on the screen cloth, granularity will move down eliminating with screen cloth greater than the particle of this layer screen mesh diameter, granularity, is fallen into down one deck and is being sieved under the effect of screen cloth vibrations less than the particle of this layer screen mesh diameter; And the material that is stuck in the sieve aperture is jumped out by the vibrations of screen cloth, prevents to stop up sieve aperture, and by different aperture sieve stratum reticulare layer screening, we have just obtained satisfactory material.
