Abstract

The invention discloses a coal dressing separator, and relates to the technical field of a centrifuge, comprising a motor, a torque flow pump, a first-stage swirler and a second-stage swirler, wherein the motor is connected with the torque flow pump by a shaft coupler, the head of the torque flow pump is fixedly connected with the first-stage swirler, a housing on the head of the torque flow pump and the first-stage swirler are designed into a whole, and a material outlet of the pump directly enters into the first-stage swirler, so that the massive middle wear-resistant pipes, elbows, valves and the like in the conventional connection mode between the pump and the first-stage swirler can be saved, and the production, manufacture and maintenance cost of the equipment can be greatly reduced; the lift of the pump can be shortened, so that the shaft power of the pump can be greatly reduced, and the energy saving effect is obvious; and the evenly-mixed raw material can directly enter into the first-stage swirler at the same speed due to the device, so that the raw coal dressing effect can be improved. Furthermore, the separator is smaller in volume, and more compact in structure, and a pipeline between the torque flow pump and the first-stage swirler is better in air impermeability and high in safety since the used pipeline is shorter.

Description

A kind of coal separation separator

Technical field

The present invention relates to the centrifugal device technical field, relates in particular to a kind of coal separation separator.

Background technology

Traditional coal separation separator comprises motor, Turo pump, one section cyclone and two sections cyclones; As shown in Figure 2; Motor is connected to Turo pump through shaft coupling and Turo pump power is provided; Turo pump is connected and sealed through the raw coal inlet of abrasion-proof pipe in the middle of the long section with one section cyclone, carries out at the coal separation separator that middle abrasion-proof pipe need bear bigger pressure and frictional force in the separation process of raw coal and gangue, and middle abrasion-proof pipe is easy to damage; And the price of middle abrasion-proof pipe is generally all very expensive, thereby has increased the manufacturing cost and the maintenance cost of said device.

Summary of the invention

Technical problem to be solved by this invention provides a kind of coal separation separator; Need not to use long middle abrasion-proof pipe just can realize separating to raw coal and gangue; Thereby improved the service life of said device; Reduce maintenance frequency, improved operating efficiency, reduced production, manufacturing and maintenance cost.

For solving the problems of the technologies described above; The technical scheme that the present invention taked is: a kind of coal separation separator; It is characterized in that comprising motor, Turo pump, one section cyclone and two sections cyclones; Motor is connected with Turo pump through shaft coupling, and the pump head of Turo pump is fixedly connected with one section cyclone, and the discharging opening on the pump head directly gets into one section cyclone.

Further scheme of the present invention is: said pump head is connected as a single entity through end and the one section cyclone that is bolted to one section cyclone, and the housing of Turo pump and one section cyclone design are one.

Adopt the beneficial effect that technique scheme produced to be: the pump head of Turo pump is fixedly connected with the end of one section cyclone; The discharging opening of Turo pump directly gets into cyclone; Thereby practiced thrift a large amount of middle abrasion-proof pipes that use, elbow, valve etc. in Turo pump and the one section cyclone tradition connected mode, in the service life of having improved said device, reduced maintenance frequency; Improve operating efficiency, reduced production, manufacturing and maintenance cost; Thereby shortened the shaft power that pump lift greatly reduces pump, energy-saving effect is obvious; And said device can make the raw material that mixes directly get into one section cyclone with same speed, improved the separating effect of raw coal.In addition, the volume of said device is littler, more compact structure, thus because the air-tightness of pipeline is better between the short Turo pump of the pipeline that uses and the one section cyclone, be not easy to take place leakage accident, safe.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the structural representation of coal separation separator in the prior art;

Wherein: 1, motor 2, shaft coupling 3, Turo pump 4, pump head 5, pipeline 6, one section cyclone 7, two sections cyclones 8, middle abrasion-proof pipe 9, feed arrangement.

The specific embodiment

As shown in Figure 1, a kind of coal separation separator comprises motor 1, Turo pump 3, one section cyclone 6 and two sections cyclones 7; Motor 1 is connected with Turo pump 3 through shaft coupling 2; The pump head 4 of Turo pump 3 is through being bolted to the end of one section cyclone 6; The housing of Turo pump and one section cyclone design for one; Discharging opening on the pump head 4 directly gets into one section cyclone 6, and the Way out of pipeline 5 is parallel with the tangential direction of one section cyclone body.

As shown in Figure 1, said two sections cyclones 7 comprise first cylindrical section that is connected with said one section cyclone, first conical section that is connected with first cylindrical section and second cylindrical section that is connected with first conical section, and the diameter of first cylindrical section is greater than the diameter of second cylindrical section.

The pump head of Turo pump is fixedly connected with the end of one section cyclone; The discharging opening of Turo pump directly gets into cyclone; Thereby practiced thrift a large amount of middle abrasion-proof pipes that use, elbow, valve etc. in Turo pump and the one section cyclone tradition connected mode, in the service life of having improved said device, reduced maintenance frequency; Improve operating efficiency, reduced production, manufacturing and maintenance cost; Thereby shortened the shaft power that pump lift greatly reduces pump, energy-saving effect is obvious; And said device can make the raw material that mixes directly get into one section cyclone with same speed, improved the separating effect of raw coal.In addition, the volume of said device is littler, more compact structure, thus because the air-tightness of pipeline is better between the short Turo pump of the pipeline that uses and the one section cyclone, be not easy to take place leakage accident, safe.
