Abstract

The utility model relates to a tripodia formula centrifuge motor drive's improvement, an electromagnetism adjustable speed motor (3) of the outside installation of centrifuge main part (1), its output shaft is direct to be linked with driving pulley (4), be connected with belt (5) between driving pulley (4) and driven pulley (6), the auxiliary motor of having saved current centrifuge, clutch and worm gear pair speed reducing system, realized that a motor accomplishes the separation and the unloading to different materials, cost and fault rate greatly reduced.

Description

Improved three-foot centrifuge

The utility model relates to the improvement of link-suspended basket centrifuge, especially the improvement of transmission gear for electric motor.

As everyone knows, when adopting centrifuge that material is taken off liquid, all adopt rotating cylinder to rotate at a high speed and separate, scraper during low speed rotation.Existing link-suspended basket centrifuge as shown in Figure 2, its drive disk assembly has main motor (7), auxiliary motor (8), clutch (9) and drive pulley (10), its operation principle is as follows: connect main motor (7) power supply, centrifugal throwing piece drives clutch (9) and by frictional force moment is reached drive pulley (10) on its axle head clutch (9) body, simultaneously, centrifugal pivoted frame shifting block in the worm gear reducer is thrown off with clutch cam under action of centrifugal force, and rotating cylinder is realized high-speed cruising; When need slowly run discharging, main motor (7) outage starts auxiliary motor (8) and passes through the worm gear reduction of speed through belt pulley, at this moment, clutch cam on the worm gear and the engagement of centrifugal pivoted frame shifting block are passed to drive pulley (10) the realization rotating cylinder low cruise that worm-wheel shaft connects with moment.Above-mentioned centrifuge has following two defectives; The one, main motor (7) rotating speed of mask work is a definite value, this just requires concentration, particle and the viscosity change scope of institute's separation of material as much as possible little, to prevent that material from reducing separative efficiency and complete machine oscillation during skewness in rotating cylinder, thereby the range of application of this centrifuge has been subjected to very big restriction; The 2nd, clutch (9) and deceleration worm gear structure are complicated, parts required precision height, thereby reliability is low, fault rate is high, needs two motors in addition, cost is very high.

The purpose of this utility model is improved existing link-suspended basket centrifuge, especially transmission device is improved, make it under the prerequisite that can carry out the high, low speed operation, cancel the parts that some easily break down, reduce cost, simultaneously, realize that rotating cylinder (2) rotating speed is adjustable continuously, all can separate effectively with material to variable concentrations, particle and viscosity.

For achieving the above object, the utility model has adopted following technical scheme, rotating cylinder (2) places in the centrifuge main body (1), the shaft extension of rotating cylinder (2) goes out the bottom of centrifuge main body (1) and is connected to driven pulley (6) in the termination, adopt an electromagnetic varispeed motor (3) to be installed in the outside of centrifuge main body (1), cancel main motor, auxiliary motor, sedimentator and worm gear deceleration system, the output shaft of electromagnetic varispeed motor (3) directly connects with drive pulley (4), is connected belt (5) between drive pulley (4) and the driven pulley (6).

By such scheme as seen, the utility model adopts an electromagnetic varispeed motor (3) to replace auxiliary motor, clutch, these several big parts of worm gear deceleration system, rate of breakdown has reduced, cost has also reduced, simultaneously, can handle the adjustment motor speed easily realizes the material of variable concentrations, particle and viscosity is separated and discharging.

Description of drawings:

Fig. 1 example structure schematic diagram;

Fig. 2 has the link-suspended basket centrifuge structural representation now.

Wherein: 1 centrifuge main body; 2 rotating cylinders; 3 electromagnetic speed-adjustings are electronic; 4 drive pulleys; 5 belts; 6 driven pulleies; 7 main motors; 8 auxiliary motors; 9 clutches; 10 drive pulleys;

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof, centrifuge main body (1) and rotating cylinder (2) are identical with existing link-suspended basket centrifuge agent structure, and electromagnetic varispeed motor (3) is selected the JZT of corresponding nominal power according to the centrifuge displacement volume _YThe L serial motors also is installed in centrifuge main body (1) outside, and its axle connects drive pulley (4) and gets final product.

Claims

1, improved link-suspended basket centrifuge, by centrifuge main body (1) with place the rotating cylinder (2) in it to constitute, the shaft extension of rotating cylinder (2) goes out the bottom of centrifuge main body (1) and is connected to driven pulley (6) in the termination, it is characterized in that: an electromagnetic varispeed motor (3) is fixed in the outside of centrifuge main body (1), its output shaft directly connects with drive pulley (4), is connected with belt (5) between drive pulley (4) and the driven pulley (6).
