Description
The present invention relates to a series of brand-new type sieving machine equipments.It utilizes absorbing vibration damping mechanics principle, and just motor can play the effect of exciting sieve, is in duty reposefully again, thereby has protected motor and saved energy consumption.
At present, dried, the wet stock grading oscillating screen that are widely used in the industry such as chemical industry, medicine, food, pottery, ore dressing have: eccentric vibrating screen, inertia vibrating screen, self-fixed centre shale shaker, hummer screen and reciprocating vibration sieve or the like, its structure roughly can reduce two big classes: to be motor sieve with the screen box vibration realizing that fuses a class; Another kind of be motor through transmission device, wait such as V belt, connecting rod to drive the reciprocating realization of screen box screening.The former characteristics are compact conformations, but electrical machinery life is short, energy consumption is high, noise is big; The latter's shortcoming is the structure bulky complex, makes maintenance difficult, now little by little is eliminated and produces.Understand the vibratory sieve of the concrete international most advanced level of making by retrieval both at home and abroad, such as the pause 32-2STST type vibratory sieve of company (Boulton) of: Britain's bohr; The circular impact screen that circular impact screen (model: 400D, 700D, 1000D, 1200D etc.) of circular impact screen that Japan Tsukijima Machine Co., Ltd produces (model: 12,26,48,70 or the like) and Japan new flourish machine worker Co., Ltd. and Japanese three English systems are done institute, Japanese Xinghe industry institute, the production of the flourish Industry Co., Ltd of Japan's rolling; The square vibratory sieve that West Germany Nei Qi company and Dorr Si Te company produce; And imitative English vibratory sieve TCS930 type of producing of Jindezhen City's dust-proof machine factory and Jindezhen City's ceramic machinery factory, TCS540 type, TQ540 type or the like are being represented the product of the eighties technical merit, they all adopt last class formation, i.e. motor and screen box disjunctor vibration.Retrieve domestic and international patent documentation, as: Chinese patent 881055093,882116428 " dried, wet stock combined type high frequency shale shaker "; BP 2123715 " method and apparatus of grain sorting "; 2126129 " vibrosieve method and apparatus "; United States Patent (USP) 4495065 " is used to screen the bifrequency vibratory sieve of granular material " and 4482455 or the like documents, all do not find and similar content and the product of the present invention, therefore, even to this day, thoroughly solve the vibratory sieve shortcoming both at home and abroad on the vibration mechanics principle of still having no way of.
The objective of the invention is to solve insurmountable problem in the reality technology, utilize absorbing body vibration damping mechanics principle, energy-conservation, simple, convenient, the suction vibrating type serial vibrating sieves that noise is little that can easily design different shape, all size, are suitable for that various gradings require.
Proposition of the present invention is the mechanics principle according to vibration damping, absorbing, shortcoming at reality two big class vibratory sieves, think: organize into an exciting source separately if motor is separated from screen box, when absorbing bulk absorption that hammer vibration energy is all constituted by screen box etc., the amplitude of motor is zero with regard to the screen box vibration occurring so.Below further narration content of the present invention.
A kind of dried, wet method material vibratory sieve is characterized in that mainly being made of three parts: absorbing body 1, excitor 2 and base plate 3, the middle series of products that evenly distributed and combine as a whole by two groups of identical Hookean springs of stiffness coefficient.Wherein: the absorbing body is made up of the interior screen box 4 that sets, lives screen cloth convenient to both, discharging opening 5, slag-drip opening 6 etc.; Excitor by upper cover plate 7, supporting plate 8, be fixed on motor 9 on the supporting plate and be installed in the eccentric block 10 of motor shaft side and rise and connect and the pillar 11 of fixation etc. is formed.A key character of the invention process is: half of each part quality summation that each part quality summation of absorbing body 1 should equal excitor 2 (is m
1=2m
2).According to above-mentioned vibratory sieve, the screen box of absorbing body series of products that can be designed to different geometric shapes (as: drum shape, square, six cylindricalitys or the like) and vary in size according to need of work (as work-yard and working face) wherein.Can be in the screen box according to the grading needs rare close screen cloth down on the two-layer or multilayer of different meshes of packing into, the outside can be provided with a pair of or several to discharging opening and slag-drip opening.The slag-drip opening that is provided with should be level with screen surface, and its direction is consistent with motor steering, in order to deslagging as early as possible.Discharging opening is provided with quantity should be according to classification requirement arrangement.The upper cover plate of excitor, the profile of supporting plate should be consistent with the screen box profile, are designed beautifully in order to shell.Motor 9 is a common electric machine, and its rotating speed is that per minute 1400 changes.The eccentric block 10 of motor shaft side is adjustable, can regulate the size of its quality and eccentricity as required.Hookean spring is a 8-24 root etc. for every layer, should select according to job stability.It is quiet after the whole machine installation, dynamically all be vertical, horizontal direction, during work ground is not had specific (special) requirements.Material is not limit.
Accompanying drawing 1 is a first embodiment of the invention, is illustrated as the structural representation that is provided with two-layer screen cloth, a pair of discharging opening and slag-drip opening;
Accompanying drawing 2 is a second embodiment of the invention, is illustrated as to be provided with three layers of screen cloth the structural representation of the two pairs of discharging openings and slag-drip opening.
With reference to the accompanying drawings, in conjunction with content of the present invention, we can be well understood to advantage of the present invention and good effect, at first be design easily flexible and changeable, it can be designed to according to different needs of work the characteristics of various sharp shapes, all size, multi-level screening, has changed traditional product and has only had circle, square two kinds of monotonicities, and it is simple and compact for structure that product is had, design easy to usely, packed and transported is good; Since motor and the work of screen box separate type, thus motor protected, reduced maintenance of equipment, also greatly save energy consumption, reduced noise, improved the working environment of workers; Owing to adopted multi-level, upper rare lower close screening principle, reduced compass screen surface pressurized rapid wear, also greatly improved operating efficiency, in a word, this product has the unrivaled advantage of reality technology, its design principle also is unprecedented, the present invention has world-class technical merit, can be widely used in each industrial circle and laboratory, laboratory, is that an original invention is created.
Following brief introduction one embodiment of the invention:
Absorbing physique amount is 6 kilograms; The excitor quality is 12 kilograms, and base plate is 4 kilograms; 8 every layer on spring, stiffness coefficient is 4.6 Newton/millimeter; Motor is 0.25 kilowatt of a JW series, and rotating speed is that per minute 1400 changes; Eccentric block weighs 5 millimeters of 0.3 kilograms, eccentricity; Screen box is a diameter * highly be 310 * 560 millimeters, and obtain after testing: absorbing body vertical amplitude is 1.2 millimeters, and the excitor amplitude has only 0.01 millimeter, and 0.1 millimeter of the amplitude absorbing body of horizontal direction, 0.01 millimeter of excitor.More than explanation, during vibratory sieve work, screen box has vibration preferably, and the vibration of excitor is zero substantially.The inventor and to the big or small vibratory sieve of difference design verify repeatedly, all get an identical result.
