Abstract
The utility model discloses a cage drum screen, including screen cloth, pivot, motor, supporting network, steel ball, retainer plate and periodic vibrator, the coaxial suit of supporting network is fixed the both ends of supporting network and screen cloth at the periphery of screen cloth, retainer plate to form an overall structure, it has a plurality of steel ball to fill between supporting network and the screen cloth, and the diameter of steel ball is less than the mesh diameter of supporting network, the pivot sets up the center at the screen cloth to through bracing piece and screen cloth fixed connection. After adopting above -mentioned structure, above -mentioned pivot can drive the supporting network and rotate with the overall structure that sieve net shape becomes, and periodic vibrator enables the above -mentioned overall structure who forms and produces periodic vibrations to make the screen cloth produce the vibrations of by a small margin. In addition, the steel ball that is located overall structure also can make a round trip to beat between supporting network and screen cloth to the messenger is located screen cloth mesh or mesh farine on every side etc. And shakes, plays the purpose of avoiding the screen cloth mesh to block up, and screening efficiency is high, sieves effectually.
Description
Technical field
The utility model relates to a kind of screen cloth, particularly a kind of cage drum screen that use when metal powder is produced.
Background technology
Metal powder, when producing, can form the particle varied in size.For ensureing stability and the uniformity of subsequent production technique, the coarse granule in metal powder and fine powder need be sieved.
Existing screening media is mainly cage drum screen and vibratory sieve, for ensureing certain production efficiency, the vibration frequency of vibratory sieve and amplitude are all comparatively large, larger vibration frequency and amplitude, destruction to a certain degree will be caused the particle in metal powder, thus fine powder amount is increased.Cage drum screen then can avoid the destruction to metal powder particle, therefore has larger application prospect.
But after cage drum screen uses a period of time, or when metal powder water content is larger, the screen cloth mesh of cage drum screen is easy to blocked.Cage drum screen after blocking, on the one hand, screening efficiency significantly declines, and on the other hand, screening effect is poor.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and provides a kind of screen cloth energy Automatic clearance, and mesh not easily blocks, and screening efficiency is high, the cage drum screen that screening effect is good.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of cage drum screen, comprises screen cloth, rotating shaft, motor, supporting network, steel ball, retainer plate and periodic vibration device; Screen cloth is caged, and supporting network coaxial package is in the periphery of screen cloth, and the two ends of supporting network and screen cloth are fixed by retainer plate, and forms an overall structure; Be filled with several steel balls between supporting network and screen cloth, the diameter of steel ball is less than the mesh diameter of supporting network; Described rotating shaft is arranged on the center of screen cloth, and is fixedly connected with screen cloth by support bar; One end of rotating shaft passes from screen cloth, and the traversing through end of rotating shaft is connected with motor; The overall structure that periodic vibration device can make supporting network and screen cloth be formed produces periodically vibrations.
Described periodic vibration device is the periodic lifting pin be arranged at below retainer plate.
Described periodic vibration device is the periodic wobble bar being arranged at retainer plate sidepiece.
Described periodic vibration device comprises several band irons of being arranged at retainer plate periphery and to be arranged at below retainer plate and the elasticity can touched mutually with band iron touches sheet.
Described steel ball is chromium steel pearl.
After the utility model adopts said structure, the overall structure that above-mentioned rotating shaft can drive supporting network and screen cloth to be formed is rotated, overall structure is while rotation, the overall structure that periodic vibration device can also make supporting network and screen cloth be formed produces periodically vibrations, thus makes screen cloth generation vibrations by a small margin.In addition, the steel ball in overall structure also can be beated back and forth between supporting network and screen cloth, thus the fine powder etc. be positioned at around screen cloth mesh or mesh is shaken off, and play the object avoiding screen cloth mesh to block, screening efficiency is high, and screening effect is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of cage drum screen of the utility model.
Wherein have:
1. screen cloth;
2. supporting network;
3. retainer plate;
4. steel ball;
5. rotating shaft;
51. support bars;
6. motor;
7. periodic wobble bar.
Detailed description of the invention
Below in conjunction with accompanying drawing and concrete better embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of cage drum screen, comprises screen cloth 1, rotating shaft 5, motor 6, supporting network 2, steel ball 4, retainer plate 3 and periodic vibration device.
Screen cloth is caged, and supporting network coaxial package is in the periphery of screen cloth, and the two ends of supporting network and screen cloth are fixed by retainer plate, and forms an overall structure.
Be filled with several steel balls between supporting network and screen cloth, the diameter of steel ball is less than the mesh diameter of supporting network.Steel ball can be beated back and forth between supporting network and screen cloth, thus carries out Automatic clearance to screen cloth.
Further, steel ball is preferably chromium steel pearl, wear-resisting, long service life.
Rotating shaft is arranged on the center of screen cloth, and is fixedly connected with screen cloth by support bar.
One end of rotating shaft passes from screen cloth, and the traversing through end of rotating shaft is connected with motor.
The overall structure that periodic vibration device can make supporting network and screen cloth be formed produces periodically vibrations.
Periodic vibration device has following several preferred embodiment:
Embodiment 1
Periodic vibration device is the periodic lifting pin be arranged at below retainer plate, and once, periodic lifting pin top will contact with retainer plate generation primary collision the every jacking of periodic lifting pin.
Embodiment 2
Periodic vibration device is the periodic wobble bar 7 being arranged at retainer plate sidepiece, and periodic wobble bar 7 can periodically swing back and forth.
Embodiment 3
Periodic vibration device comprises several band irons of being arranged at retainer plate periphery and to be arranged at below retainer plate and the elasticity can touched mutually with band iron touches sheet.
The overall structure that above-mentioned rotating shaft can drive supporting network and screen cloth to be formed is rotated, and overall structure is while rotating, and the overall structure that periodic vibration device can also make supporting network and screen cloth be formed produces periodically vibrations, thus makes screen cloth generation vibrations by a small margin.In addition, the steel ball in overall structure also can be beated back and forth between supporting network and screen cloth, thus the fine powder etc. be positioned at around screen cloth mesh or mesh is shaken off, and play the object avoiding screen cloth mesh to block, screening efficiency is high, and screening effect is good.
More than describe preferred embodiment of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple equivalents to the technical solution of the utility model, these equivalents all belong to protection domain of the present utility model.
