Abstract
The utility model relates to an energy-saving spindle head of a mine spiral classifier. The energy-saving spindle head comprises a shell, a high density abrasive rubber block, a minor axis, a ball grinder cast-iron sleeve, a water filling hole and lifting lugs. The high density abrasive rubber block is embedded in the shell; the minor axis and the ball grinder cast-iron sleeve are in interference fit and then are inserted in a round hole of the high density abrasive rubber block to form a running mechanism through an external torsion torque. In the running process, a gap is designed between the round hole of the abrasive rubber block and the ball grinder cast-iron sleeve, and water is filled in the water filling hole between the lifting lugs, therefore, the utility model plays a role of temperature reduction on the one hand, and prevents ore slurry from depositing in the gap between the ball grinder cast-iron sleeve and the rubber block on the other hand because the connector of the water filling hole is connected to a water pipe of industrial running water to enable the water pressure to be far larger than that of the outside ore slurry, thereby effectively reducing the frication and prolonging the service life of the ball grinder cast-iron sleeve and the rubber block. And meanwhile, the energy-saving spindle head is economic, has low cost and long use period and does not need repairing.
Description
Technical field
The utility model relates to the energy-conservation spindle nose of a kind of mining spiral classifier.
Background technology
Along with the high speed development of national science technology with under the ever-increasing prerequisite of the demand of the energy, the DEVELOPMENT PROSPECT of mineral resources is indubitable, impels the preparation equipment demand constantly to increase.Existing mining spiral classifier spindle nose all adopts the bearing-type transmission, and working environment is in the water density 2.0-2.6 ore pulp doubly in density.Structure and principle thereof are: in the bear box of casting, two bearings (thrust ball bearing with flat seat and radially aligning cylindrical bearing) are installed, are undertaken oilyly by the butter hole on the housing, carry out separating of ore pulp and internal bearings with sealing ring and gland.In using one section process (lacking one month, have half a year to one year), occur the driving motor load usually and increase suddenly, the bearing locking when finding during through every the inspection in the spindle nose.The locking reason is generally effect that sealing ring loses sealing and causes ore pulp to enter making it in the bearing that load increases, locking.Be exactly to forget that adding butter to bearing is lubricated in addition, bearing is through dry friction, and temperature constantly raises, and can't turn round after bearing deforms.Simultaneously financial cost height, maintenance complicated, service time of weak point also is the problem of the maximum of existence at present.
Summary of the invention
The utility model purpose is, provide a kind of mining spiral classifier energy-conservation spindle nose, this energy-conservation spindle nose is made up of housing, high-density wear-resistant block rubber, minor axis, nodular cast iron cover, water injection hole and hanger, the high-density wear-resistant block rubber is embedded in the housing, minor axis and nodular cast iron cover are by after the interference fit, penetrate in the circular hole of high-density wear-resistant block rubber, formed a works through external torque.In operation process, because design is gapped between abrasive rubber piece circular hole and the nodular cast iron cover, carry out water filling by the water injection hole between the hanger, play the effect of cooling on the one hand; The water injection hole interface is connected on the industrial running water pipe on the other hand, hydraulic pressure is far longer than the hydraulic pressure of outside ore pulp, prevented that ore pulp is deposited in the gap between nodular cast iron cover and the block rubber, effectively reduced friction, prolonged the service life of spheroidal graphite cast-iron cover and block rubber.The energy-conservation spindle nose financial cost of mining spiral classifier of the utility model design simultaneously is low, need not overhaul, life cycle long (at least two years).
The energy-conservation spindle nose of a kind of mining spiral classifier described in the utility model, form by housing, high-density wear-resistant block rubber, minor axis, nodular cast iron cover, water injection hole and hanger, be embedded in high-density wear-resistant block rubber (2) at housing (1), one circular hole is arranged in the middle of the high-density wear-resistant block rubber (2), in circular hole, be provided with nodular cast iron cover (4) and minor axis (3), the fixing hanger (6) on the top of housing (1), the top of housing (1) has water injection hole (5).
Minor axis (3) forms integral body and is inserted in the circular hole with nodular cast iron cover (4) interference fit.
One end of water injection hole (5) docks with spheroidal graphite cast-iron cover (4).
The energy-conservation spindle nose of mining spiral classifier described in the utility model adopts nodular cast iron cover and abrasive rubber piece to substitute thrust bearing and the journal bearing in the existing equipment, replaces butter with recirculated water.Its characteristics are: do the carrying force with the nodular cast iron cover,, turn round in the abrasive rubber hole, thereby reduce cost as medium with recirculated water, improved service life, need not maintenance, only need to change processing after reaching life cycle and get final product.

The specific embodiment
Further describe and provide embodiment below in conjunction with accompanying drawing
The energy-conservation spindle nose of a kind of mining spiral classifier described in the utility model, be by housing, the high-density wear-resistant block rubber, minor axis, the nodular cast iron cover, water injection hole and hanger are formed, be embedded in high-density wear-resistant block rubber (2) at housing (1), one circular hole is arranged in the middle of the high-density wear-resistant block rubber (2), in circular hole, be provided with nodular cast iron cover (4) and minor axis (3), minor axis (3) forms integral body with nodular cast iron cover (4) interference fit and is inserted in the circular hole, the fixing hanger (6) on the top of housing (1), the top of housing (1) has water injection hole (5), and an end of water injection hole (5) docks with spheroidal graphite cast-iron cover (4).In operation process, because design is gapped between abrasive rubber piece circular hole and the nodular cast iron cover, carry out water filling by the water injection hole between the hanger, play the effect of cooling on the one hand, the water injection hole interface is connected on the industrial running water pipe on the other hand, and hydraulic pressure is far longer than the hydraulic pressure of outside ore pulp, has prevented that ore pulp is deposited in the gap between nodular cast iron cover and the block rubber, effectively reduce friction, prolonged the service life of spheroidal graphite cast-iron cover and block rubber.The energy-conservation spindle nose financial cost of mining spiral classifier of the utility model design simultaneously is low, need not overhaul, life cycle long (at least two years).
