Embodiment 1

[0045]Please refer to Fig. 1-shown in Fig. 5, a kind of coal slime rubbing equipment of preferred embodiment of the present invention, it mainly comprises motor, speed reducer 2, gear box 4, feed bin 6, discharge hopper 9, rotating shaft 7 , Coupling 5.

[0046] As shown in FIG. 1 , the motor, the reducer 2 , the gear box 4 , the feed bin 6 and the discharge hopper 9 are installed on the underframe 8 . It is transmitted to the reducer 2 through the pulley, the reducer 2 and the gear box 4 are connected together through the coupling 3, and the gear box 4 and the rotating shaft 7 are connected together through the coupling 5.

[0047] As shown in Figure 2, a pair of oppositely rotating rotating shafts 7 are equipped with a helical cutting blade and a non-helical cutting reamer blade. The cutting blades are divided into left-handed and right-handed. The cutting blades with the same rotation direction are installed on the same shaft. The end of each rotating shaft 7 and the hoppe...

Embodiment 2

[0052] A coal slime kneading equipment according to a preferred embodiment of the present invention, the spiral cutting blade is fan-shaped when viewed in the axial direction, and the fan-shaped angle 13 and the fan-shaped angle 15 are each 75°. The phase angle 14 of the left-handed cutting blade 10 and the phase angle 16 of the right-handed cutting blade 11 differ by 80°, the phase angle 14 is 120°, the phase angle 16 is 40°, and the phase angle 17 and the phase angle 18 are equal to 120° °, 120 power sources adopt hydraulic motors, and other structures are the same as in Embodiment 1

Embodiment 3

[0054] A kind of coal slime kneading equipment of preferred embodiment of the present invention, described helical cutting blade is viewed as fan-shaped along axial direction, and fan-shaped angle 13 and fan-shaped angle 15 are each 100 °, and the phase angle 14 of left-handed cutting blade 10 and right-handed The phase angle difference of the phase angle 16 of the rotary cutting blade 11 is 100°, the phase angle 14 is 150°, the phase angle 16 is 50°, the phase angle 17 and the phase angle 18 are equal to 150°, the power source adopts a hydraulic motor, other structures Same as Example 1

[0055] The working principle of the present invention is that after dehydration, the coal slime enters the crushing device from the feed bin 6, and is first crushed through the area shown in Figure 3. The large coal slime is cut by the spiral cutting blade, and at the same time, it is cut along the axis direction under the action of the spiral surface. , move from the feed port to the 9 end ...

Abstract

The present invention relates to a coal slurry twine and the device, wherein, the power source, the reducer, the gear box, the feed bin and the material outlet hopper are arranged on the bottom frame, and the transmission shaft is a pair of shafts rotating in an opposite direction. The two rotating shafts are respectively provided with spiral cutting blades with different rotating direction, and synchronously the two rotating shafts are respectively provided with the non spiral cutting blades. The cutting blade on the crossed part of the phase positions of the left rotating cutting blade and the right cutting blade has the cutting up effect for the coal slurry. The cutting blade on the equal part of the phase positions of the left rotating cutting blade and the right cutting blade has the tearing up effect for the coal slurry. The invention makes cutting and tearing to the coal slurry after dehydration by cutting and tearing methods, and synchronously makes the coal slurry transported along the axial direction. When cutting and tearing the material with certain glutinosity, the phenomenon of glued connecting, agglomeration and blocking is unlikely to be produced, and the invention particularly has good effect for the coal slurry smashing after dehydration.

Description

technical field [0001] The invention relates to a device for crushing and conveying coal slime produced after raw coal is washed and dehydrated, in particular to a coal slime kneading equipment. Background technique [0002] The dehydrated coal slime generally has a moisture content between 20-35%, is lumpy, sticky, and becomes cake-like after extrusion, with certain extensibility. Before it is made into a slurry (moisture content about 35%) and transported to the boiler for combustion with a pipe, it is usually broken to facilitate uniform mixing and slurrying in the mixing chamber. [0003] At present, the known crushing equipment includes jaw crusher, hammer crusher, cone crusher, impact crusher, and roll crusher. The structures and working principles of these crushers are introduced as follows. [0004] The crushing method of the jaw crusher is extrusion, relying on the movable jaw plate to do periodic reciprocating motion, and placing the material between the two jaw p...
