Vibratory sieve is to utilize the reciprocating rotary type that oscillator exciting produces vibrate and work, the upper rotation weight of oscillator makes compass screen surface produce plane whirling vibration, lower rotation weight makes compass screen surface produce conical surface rotary vibration, and its symphyogenetic effect makes compass screen surface generation revolve again type vibration.Vibratory sieve is mainly divided into linear vibrating screen, round vibratory sieve and high frequency shale shaker, wherein circular impact screen is a kind of vibratory sieve that does round vibration, multilayer number, new high-efficiency, its general barrel-type eccentric shaft vibration exciter and eccentric block adjusting amplitude of adopting, material screen drops down line length, screening specification is many, there is reliable in structure, exciting force is strong, screening efficiency is high, vibrating noise is little, sturdy and durable, easy to maintenance and use the features such as safety, be widely used in the stock grading of the industries such as mine, building materials, traffic, the energy, chemical industry.
Circular shale shaker generally adopts barrel-type eccentric shaft vibration exciter, can be divided into two kinds of grease lubrication and thin oil lubricants by lubricating system, adopts the vibrator of grease lubrication, and its mobility of lubricating grease used is poor, and lubricated, heat radiation, dust-proof effect are also poor; And the vibrator of employing thin oil lubricant, it dispels the heat, lubricant effect is relatively good, but easily leakage of oil, machining accuracy, matching requirements to hermetically-sealed construction are all higher, and cost of manufacture is also relatively high.The vibrator of thin oil lubricant in use, the centrifugal force that eccentric block produced that lubricant in bearing block is easily turned round in vibration processes throws away, or use because of long-term, its sealing is reduced under the condition of vibration oil leakage phenomenon occurs, will easily make like this bearing in bearing block suffer damage, not only affect operating efficiency, and reduce the service life of bearing.On the other hand, circular shale shaker is applied to the classification of the materials such as mine, building materials, chemical industry conventionally, and working environment is poor, and in long-term work, dust easily stops up bearing, and the dust-proof effect of vibrator is also poor.
Utility model content
The utility model is disclosed is a kind of sealing device of vibrating sieve vibrator, its main purpose is to overcome prior art above shortcomings and shortcoming, pass through improvements over the prior art, overcome its bearing and be easily subject to dust pollution, increase the service life of bearing, make the working environment of vibrator in relative sealing state simultaneously, not only utilize the lubricated running of vibrator, and the heat that can well eccentric block be produced is taken away.
The technical solution adopted in the utility model is as follows:
A kind of sealing device of vibrating sieve vibrator, involving vibrations sieve nest, be installed in the rotating spindle of vibration on sieve nest, be arranged on rotating spindle and with the vibrator of rotating spindle rotation and the motor being in transmission connection with rotating spindle, on two lateral walls of described vibration sieve nest, be arranged with respectively the chamber of a sealing, the two ends of described rotating spindle are with the installation of respectively in the chamber of these vibration sieve nest both sides, and this vibrator is installed on the rotating spindle in this chamber; The input transmission of the output of described motor by soft connection device and this rotating spindle in succession.
Further, described soft connection device comprises jointed coupling and chain jockey, and this jointed coupling is connected with the input of rotating spindle, and this chain jockey is connected with the output of jointed coupling, motor respectively.
Further, in described chamber, fill and establish lubricating oils.
Further, the top of described chamber is provided with air inlet/outlet and oil filler, and the bottom of chamber is equiped with oil drain out.
Further, on described chamber, be also provided with one deck for the cold water layer to chamber cooling.
By above-mentioned known to description of the present utility model, compared to the prior art, the utility model has the advantage of:
The utility model passes through improvements over the prior art, be symmetrically arranged with the chamber of relative sealing at two lateral surfaces of vibration sieve nest, in chamber, generally all can be full of in use lubricating oils, make chamber become the grease chamber of a sealing, the output of motor is in transmission connection by soft connection device with the rotating spindle in chamber, vibrator on rotating spindle is in the chamber running of sealing, inside not only do not worry the leak problem of bearing block, there is good dust-proof effect, and the heat that eccentric block on vibrator produces can be taken away well by the cold water layer on chamber, radiating effect is better.The utility model improvement uniqueness, simplicity of design, rational in infrastructure, practical, in actual application, its effect is very obvious, not only increases the service life of the bearing in vibrator, has reduced the maintenance cost of bearing, and improved the service efficiency of whole vibratory sieve, produce good technology effect.
