Detailed description of the invention
For making the object of the application and technical scheme clearly, be clearly and completely described below in conjunction with the technical scheme of the embodiment of the present application to the application.Obviously, described embodiment is a part of embodiment of the application, instead of whole embodiments.Based on the embodiment of described the application, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of the application's protection.
A kind of screening machine described in the application, the screen drum comprising transmission mechanism and be rotationally connected with it.
As shown in Figure 1, described screen drum comprises outer screen drum body 5 and interior screen drum body 4, and interior screen drum body 4 is fixedly installed in outer screen drum body 5, and there is gap between interior screen drum body 4 and outer screen drum body 5, interior screen drum body 4 and outer screen drum body 5 synchronous axial system; Interior screen drum body 4 grows about about 0.5 meter than outer screen drum body 5, and one end of interior screen drum body 4 is provided with thick material discharging opening 14, and one end of outer screen drum body 5 is provided with fine material discharging opening 13, can separate splicing.Such design is to make screened material through the two-layer screening of interior screen drum body 4 with outer screen drum body 5, solving in prior art can not disposable screening problem repeatedly, correspondingly, solve in prior art and often screen once, need the waste changing screen drum and man-hour, manpower, for manufacturing enterprise provides cost savings, bring benefit.
Screen drum body 4 in the above, gap between outer screen drum body 5 and receiving hopper 12 ensure to rotate do not interfere prerequisite under control the smaller the better.
Preferably, described interior screen drum body 4 is welded into one with outer screen drum body 5.
Preferably, described screening machine also comprises dust stratification cover 3, and dust stratification cover 3 is sheathed on outside outer screen drum body 5, and there is certain interval between dust stratification cover 3 and outer screen drum body 5.Outer screen drum body 5 can fill comparatively fine screen mesh, interior screen drum body 4 can fill comparatively wide-meshed screen.Screened material is after interior screen drum body 4 with the two-layer screening of outer screen drum body 5; can a large amount of thin dusts be thrown away outside outer screen drum body 5 in rotation process; outside outer screen drum body 5, sheathed dust stratification cover 3 may be used for collecting these thin dusts; in the below of dust stratification cover 3, useless grey discharging opening 10 is set; prevent them from flying away in surrounding air; prevent air pollution, very environmental protection.
Preferably, described dust stratification cover 3 top and the bottom adopt loose-leaf to connect, and make it directly to dig and open.
Further, the lateral wall of described outer screen drum body 5 is fixedly connected with several holder rails 2, described transmission mechanism comprises transmission mechanism 15, motor 8 and support roller 11, the output of motor 8 is connected with transmission mechanism 15, transmission mechanism 15 connects several support rollers 11, motor 8 drives transmission mechanism 15 to rotate, and transmission mechanism 15 drives support roller 11 to rotate, and makes holder rail 2 drive outer screen drum body 5 and interior screen drum body 4 to rotate between support roller 11 and holder rail 2 by frictional drive.
Preferably, described holder rail 2 and support roller 11, bracing frame 9, dust stratification cover 3 can have several.
Preferably, be also provided with coupling spindle 7 between motor 8 and transmission mechanism 15, motor 8 is connected by coupling spindle 7 with reductor 6.
Preferably, described transmission mechanism 15 is universal drive shaft.
Further, described screening machine also comprises bracing frame 9, described bracing frame 9 slant setting at an angle.Dust stratification cover 3 is set up on bracing frame 9, and the above motor 8, coupling spindle 7, reductor 6 are all arranged on bracing frame 9.
Further, the top and the bottom loose-leaf of described receiving hopper 12 connects, and makes it to dig and opens.
In in the application, one end of screen drum body 4 is connected with thick material discharging opening 14, and the other end is provided with charging aperture feed bin 1.
During use, required order number sieve net is contained in interior screen drum body 4 respectively, on outer screen drum body 5, required material screening is sent into charging aperture feed bin 1, start motor 8, reductor 6 drives outer screen drum body 5 to rotate, material screening will produce rotation thereupon, continue reinforced, thus required material screening is moved forward always, the material being less than sieve number is by the process that rotates at barrel, drop out again and again respectively from sieve screen apertures, finally fall in useless grey discharging opening 10, other materials that cannot drop from sieve aperture fall in the fine material discharging opening 13 be sent to respectively in receiving hopper 12 and thick material discharging opening 14 on transmitting device.Because dust stratification cover 3 is fixed on outer screen drum body 5 outside, therefore there will not be dust raising phenomenon, meet the requirement of environmental protection.
Obviously, according to above-mentioned, as required, ask rail 2 and support roller 11, bracing frame 9, dust stratification cover 3 that can several be set.In addition, the interior screen drum body 4 in multiple dust stratification cover 3, outer screen drum body 5 can be equipped with different meshes screen cloth, and control charging rate, so just can meet and filter out different meshes material, also reach the demand controlling material respectively, thus meet formation and be incorporated to production line demand, improve production efficiency.
In the application, interior screen drum body 4, outer screen drum body 5 can be tightly connected with the junction of dust stratification cover 3, to reach best pick-up performance.
When use in screen drum on sieve breakage time, only need open the top of the first half installing the dust stratification cover 3 that loose-leaf connects additional and the same receiving hopper 12 adopting top and the bottom loose-leaf to connect, then lower damaged screen cloth screen drum is hung with row, hang on screen drum for subsequent use again, the upper part finally covering dust stratification cover 3 and receiving hopper 12 can complete replacing, and whole process only needs about 5 minutes, thus ensures continuous seepage, damaged screen cloth can be used as screen drum for subsequent use after free time can be utilized to change.
