Abstract
The utility model discloses a high-frequency magnetite powder vibration sieve, which is characterized by comprising a support frame, wherein a group of sieve boxes are sequentially and fixedly connected onto the support frame from top to bottom, a group of vibration exciters are respectively and fixedly connected with two sides of the sieve boxes, the output ends of the vibration exciters are connected with vibration exciting rods, composite screen nets are fixedly connected onto the sieve boxes, and the vibration exciting rods are leaned and connected with the composite screen nets. Because the high-frequency magnetite powder vibration sieve adopts the high-frequency electromagnetic vibration exciters as vibration exciting sources, the sieve nets carry out high-speed oscillation, the loose delamination of particles is enhanced, the separation speed of high-density useful minerals is accelerated, meanwhile, the contact probability of sieve meshes and materials smaller than the separation granularity is increased, and better conditions are provided for the material separation. In addition, the structural form of the laminated screen nets and composite nets is adopted, the delamination of the materials according to the granularity is accelerated, the sieve nets have better wear resistance performance, the service life is long, and the sieving effect is enhanced.
Description
Technical field
The utility model belongs to the vibratory sieve equipment technical field, especially relates to a kind of high frequency magnetite powder vibratory sieve.
Background technology
China produces the production technology of dense media magnetite powder, i.e. ball milling--magnetic separation--cyclone classification technology, and this technology also is that China produces the most widely used technology of magnetite powder.Cyclone classification technology is wherein used spiral classifier or hydrocyclone basically; Because spiral classifier or hydrocyclone all carry out stock grading by settlement law; Classification efficiency is low; Be generally 30-40%, the valuable mineral that especially density (proportion) is big usually causes accumulation in sand return.Wherein, in the closed circuit grinding flow process that spiral classifier and ball mill are formed, have only the qualified products about 30% in a grinding circuit, to circulate in the sand return, cause valuable mineral to cross pulverizing, reduce the ball mill treating capacity, increased electric energy and metal consumption.And hydrocyclone is wayward on sharpness of separation, and product granularity is difficult to reach optimum efficiency.If overflow is too thin, then output is less, and is overground serious; If overflow is too thick, then do not reach granularity requirements.To above-described these problems, in mineral processing in China fine grading link, can also use the equipment such as MICHAEL DRAKE high frequency sieve of mechanical high frequency sieve, fixedly nylon fine screen and import abroad to carry out classification work.But also there is the limitation of self in these equipment, and for example fixedly nylon fine screen is easy for installation, long service life; The regular maintenance expense is low, but percent opening is low, and screening efficiency is low; Disposal ability is poor, and the sieve seam is also generally more than 0.1mm, so be eliminated gradually at present; Domestic mechanical high frequency sieve is installed comparatively complicated, and screen cloth is lower service life, and reliability is still waiting to improve, and the regular maintenance expense is higher; The screening effect of the MICHAEL DRAKE high frequency sieve of external import is better, but the complicacy of installation, expensive, accessory is difficult for supply at home.
Summary of the invention
It is simple that the purpose of the utility model provides a kind of installation, and screening efficiency is high, and the hierarchical processing ability is strong, and screen life-span is long, the high frequency magnetite powder vibratory sieve that the regular maintenance expense is few.
The purpose of the utility model realizes through following technical proposals:
A kind of high frequency magnetite powder vibratory sieve of the utility model; It is characterized in that comprising support; On this support to down and on the one group of screen box that has been fixedly connected sequentially, be fixedly connected with one group of vibrator respectively in the both sides of this screen box, the output of this vibrator is connected with exciting rod; On described screen box, be fixedly connected with compound screen cloth, described exciting rod is abutted against with described compound screen cloth mutually.
Described vibrator is the high-frequency excitation device.
The assembly that described compound screen cloth is made up of upper strata macropore screen cloth and lower floor's aperture screen cloth, described upper strata macropore screen cloth and described lower floor aperture screen cloth are by vulcanization of rubber bonding connection.
Described compound screen cloth, the aperture that is positioned at the upper strata screen box is bigger than the aperture that is positioned at lower floor's screen box.
The advantage of the utility model:
1) because the utility model adopts the high-frequency electromagnetic exciter as exciting source; Screen cloth is shaken at a high speed; Increased the loose layering of particle; Strengthened the speed of isolating of big density valuable mineral, increased the probability that contacts with sieve aperture less than the partition size material simultaneously, for the separation of material provides condition better;
2) because the utility model has adopted layer vibrating screen; Relative motion is arranged between the screen cloth, quickened material by the granularity layering and make difficult sieve particle see through sieve aperture with comparalive ease to become undersized product, one step of gradation sizing work is accomplished; Floor space is little, has improved capacity utilization and screening efficiency;
3) because every layer of screen cloth of the utility model all adopts the version of composite web, make screen cloth more wear-resisting, long service life has strengthened screening effect.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Further specify the specific embodiment of the utility model below in conjunction with accompanying drawing.
As shown in Figure 1; A kind of high frequency magnetite powder vibratory sieve is characterized in that comprising support 5, on this support 5 to down and on the one group of screen box 1 that has been fixedly connected sequentially; Be fixedly connected with one group of vibrator 3 respectively in the both sides of this screen box 1; The output of this vibrator 3 is connected with exciting rod 4, on described screen box 1, is fixedly connected with compound screen cloth 2, and described exciting rod 4 is abutted against with described compound screen cloth 2 mutually.
Described vibrator 3 is the high-frequency excitation device.
The assembly that described compound screen cloth 2 is made up of upper strata macropore screen cloth and lower floor's aperture screen cloth, described upper strata macropore screen cloth and described lower floor aperture screen cloth are by vulcanization of rubber bonding connection.
Described compound screen cloth, the aperture that is positioned at the upper strata screen box is bigger than the aperture that is positioned at lower floor's screen box.
The screen box 1 of the utility model is motionless, and the basis is not had dynamic load basically, so the equipment installation need not the basis; Easy for installation, the high-frequency excitation device through being fixed on screen box 1 both sides drives described exciting rod 4 and makes the high frequency reciprocally swinging as exciting source when vibrator 3 work; Because exciting rod 4 is abutted against with compound screen cloth 2 mutually, cause compound screen cloth 2 to produce dither, increased the loose layering of particle; Owing to adopted layer vibrating screen, the aperture of upper strata vibrating screen mesh is bigger than the aperture of lower floor vibrating screen mesh, and relative motion is arranged between the screen cloth again; Quickened material by the granularity layering and make difficult sieve particle see through sieve aperture with comparalive ease to become undersized product; One step of gradation sizing work is accomplished, and floor space is little, has improved capacity utilization and screening efficiency.Every layer of screen cloth all adopts the version of composite web, makes screen cloth more wear-resisting, and long service life has strengthened screening effect.
