Description

Constant formula centrifugal dehydrator

Technical field

The utility model relates to a kind of centrifugal dehumidifier, is specially a kind of constant formula centrifugal dehydrator.

Background technology

At present, centrifugal drier generally is to be connected with dehydration bucket bottom by transmission connection piece by motor, supporting and driving dehydration barrel are rotated synchronously, under action of centrifugal force, slough moisture content contained in the washings, rotate at a high speed and the vibrations that cause for fear of dehydration barrel and motor, motor adopts spring stack to be bearing in housing bottom usually.The dewaterer of this kind structure is easy to take place the phenomenon that dehydration barrel is waved in actual use, and produces strong vibrations and noise with the casing collision, and when serious, dewaterer can't dewater or be badly shaken.Trace it to its cause, mainly contain following 3 points, the one, the distance between dehydration barrel and the motor is too far away, and the dehydration barrel center of rotation causes its radius of clean-up bigger at the motor place, and dehydrated thing is put into dehydration barrel, imbalance is arranged slightly, phenomenon will occur waving, even be difficult to start; The 2nd, when dehydration barrel starts, because motor can make the spring stack run-off the straight, cause the center of rotation of dehydration barrel to change, disequilibrium, when dehydration barrel begins to rotate, will wave phenomenon, and dehydrated thing is heavy more, spring stack run-off the straight degree is big more when starting, the corresponding increase of degree of waving meeting of dehydration barrel; The 3rd, when ground was uneven, the axle center of dehydration barrel lost vertically, also can cause dehydration barrel to wave.Up to the present, to wave phenomenon be the difficult problem that people need to be resolved hurrily always to dehydration barrel.

Summary of the invention

The utility model is in order to solve existing centrifugal drier because unreasonable structure is easy to take place dehydration barrel and waves phenomenon, and the problem with casing collision generation sharp pounding and noise provides a kind of constant formula centrifugal dehydrator.

The utility model is to adopt following technical scheme to realize: constant formula centrifugal dehydrator, comprise casing, the dehydration electric motor that places the dehydration barrel in the casing and be positioned at the dehydration barrel below, dehydration bucket bottom is connected with rotating shaft by containment member, the universal base that the rotating shaft epimere is set with multi-directional ball and complements one another with it, the universal base both sides are fixed with the support that is fixed on casing inner wall, be provided with the spacer pin of circumferencial direction between multi-directional ball and the universal base, multi-directional ball top, the bottom respectively and upper bearing (metal) and lower bearing are installed between the rotating shaft, the multi-directional ball lower end is connected with the axle bed of lower bearing by sleeve; The rotating shaft hypomere is provided with suspension bracket, and dehydration electric motor is suspended on the suspension bracket, and the output shaft of dehydration electric motor is connected with rotating shaft is vertical, and the axle bed of suspension bracket and lower bearing is fixed.

On the axle bed of described lower bearing and be positioned at the rotating shaft both sides and be fixed with and hold out against spring, the sleeve outside is fixed with the supporting universal base, holding out against the spring upper end contacts with supporting universal base below, because multi-directional ball can produce downward movement tendency under the effect of dehydration barrel and built-in washings, and hold out against spring and support universal base and can universal base be played a supporting role, so significantly reduced the resonance between multi-directional ball and the universal base, reduced the vibrations and the noise of whole dewaterer then.

Compared with prior art, adopt structural design of the present utility model, have the following advantages:

1, sets up the multi-directional ball and the universal base of the motion of restriction circumferencial direction at the rotating shaft epimere, make the center of rotation of dehydration barrel be promoted to the multi-directional ball place by original motor place, shortened the radius of clean-up of dehydration barrel, and no matter be owing to the ground injustice, or dehydrated thing place imbalance etc. reason cause the unbalanced problem of dehydration barrel, when dehydration barrel starts, all can regulate the perpendicularity of rotating shaft automatically;

2, adopting spring stack to be supported on bottom of shell with original dehydration electric motor compares, the utility model is provided with suspension bracket at the rotating shaft hypomere, dehydration electric motor is suspended on the suspension bracket, this moment, dehydration electric motor can be used as mass, effectively reduced because the interior dehydrated thing of dehydration barrel is heavy more, and the phenomenon that causes dehydration barrel to wave;

3, support universal base and the setting that holds out against spring, can further reduce the vibrations and the noise of whole dewaterer;

In a word, the dewaterer after the utility model improves is in running, dehydration barrel can not take place wave, bump the cylinder problem, total noise of centrifuge and mechanical oscillation obviously reduce, and reasonable in design operates steadily, prolonged complete machine service life, fault rate is low, and is easy and simple to handle, can be widely used in daily washing dehydration field, also can be applicable to the dehydration of industrial circle, have certain popularization value.
