Background technology
Present generic centrifuge, its structure more complicated, motor is by belt wheel and belt drives drum rotating, as everyone knows, season cracking and wearing and tearing can take place in belt in long-term use, if can not before the belt fracture, in time change, just may lead to a disaster; Moreover what present feed pipe adopted is straight tube mostly, the charging of inconvenient lathe smear metal liquid; In addition, present rotary drum, employing all be the rotary drum that offers filter opening on its sidewall, manufacturing cost is higher.
Summary of the invention
Technical problem to be solved by this invention is: a kind of machine cut liquid special centrifugal machine simple in structure, safe and reliable, high efficiency is provided.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: machine cut liquid special centrifugal machine, comprise: frame, frame is provided with bearing, bearing is provided with shell, be provided with rotary drum in the shell, the bottom surface of bearing is provided with motor, the output shaft of motor passes bearing and links to each other with the hollow shaft sealing that is arranged on the bottom of the drum, the top of shell offers charging aperture, charging aperture is provided with feed pipe, the top of rotary drum is provided with lip ring, leaves overfall between lip ring and the feed pipe, is set with the hollow shaft sealing ring that seals mutually with bearing on the hollow shaft, hollow shaft sealing ring and shell, form the fluid storehouse between rotary drum and the bearing, the bottom of shell is provided with the liquid outlet that communicates with this fluid storehouse.
The output shaft of described motor comprises with the structure that specifically is tightly connected of hollow shaft: tightening bolt and the bolt seal circle that matches with tightening bolt, described output shaft stretches in the hollow shaft, be provided with axial square key between output shaft and the hollow shaft, hollow shaft is provided with shaft-cup, be provided with the shaft-cup sealing ring between hollow shaft and the shaft-cup, shaft-cup is provided with up big and down small ladder hole, the top of output shaft offers the retaining thread hole of matching with tightening bolt, tightening bolt puts the bolt seal circle and passes ladder hole and tighten up in the retaining thread hole, makes the bolt seal circle be arranged in the epimere macropore of shoulder hole.
Further technical problem to be solved by this invention is: a kind of charging machine cut liquid special centrifugal machine easily is provided.
For solving above-mentioned further technical problem, the technical solution adopted in the present invention is: the top of described feed pipe is up big and down small horn mouth, makes whole feed pipe form funnel-form.
Be provided with beam between described bearing and the frame.
The invention has the beneficial effects as follows: structure of the present invention is very simple, and the output shaft and the rotary drum of motor are direct-connected, have avoided the bel-drivenn drawback, makes the safe and reliable to operation of centrifuge; And, need not offer filter opening on the sidewall of this rotary drum, greatly reduce manufacturing cost; In addition, owing to adopted funnelform feed pipe, greatly facilitate the charging of solidliquid mixtures such as lathe smear metal liquid; The employing of beam can reduce noise so that the running of rotary drum is more steady.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, machine cut liquid special centrifugal machine of the present invention, comprise: frame 1, frame 1 is provided with bearing 9, bearing 9 is provided with shell 8, be provided with rotary drum 4 in the shell 8, be placed with collecting bag 5 in the rotary drum 4, the bottom surface of bearing 9 is provided with motor 3, the output shaft 10 of motor 3 passes bearing 9 and links to each other with hollow shaft 12 sealings that are arranged on rotary drum 4 bottoms, as shown in Figure 2, the output shaft 10 of described motor 3 comprises with the structure that specifically is tightly connected of hollow shaft 12: tightening bolt 13 and the bolt seal circle 14 that matches with tightening bolt 13, described output shaft 10 stretches in the hollow shaft 12, be provided with axial square key 11 between output shaft 10 and the hollow shaft 12, hollow shaft 12 is provided with shaft-cup 17, be provided with shaft-cup sealing ring 15 between hollow shaft 12 and the shaft-cup 17, shaft-cup 17 is provided with up big and down small ladder hole, the top of output shaft 10 offers the retaining thread hole of matching with tightening bolt 13, tightening bolt 13 puts bolt seal circle 14 and passes ladder hole and tighten up in the retaining thread hole, makes bolt seal circle 14 be arranged in the epimere macropore of shoulder hole; The top of described shell 8 offers charging aperture, charging aperture is provided with funnelform feed pipe 7, the top of rotary drum 4 is provided with lip ring 6, leave ring-type overfall 18 between lip ring 6 and the feed pipe 7, be set with the hollow shaft sealing ring 16 that seals mutually with bearing 9 on the hollow shaft 12, form fluid storehouse 19 between hollow shaft sealing ring 16 and shell 8, rotary drum 4 and the bearing 9, the bottom of shell 8 is provided with the liquid outlet 81 that communicates with this fluid storehouse 19.In the present embodiment, be provided with beam 2 between described bearing 9 and the frame 1.
Operation principle of the present invention is: mixed liquor enters rotary drum 4 from feed pipe 7, rotary drum 4 is by motor 3 direct-connected and drive rotations at a high speed, under action of centrifugal force, solid phase composition in the mixed liquor accumulates on the collecting bag 5 that is covered in rotary drum 4 madial walls because proportion is big, and liquid phase then distributes near rotary drum 4 axis one side.Along with continuous injection mixed liquor, liquid phase can be overflowed from the liquid head piece 18 between lip ring 6 and the feed pipe 7, enters into fluid storehouse 19, then, and from liquid outlet 81 outflows of shell 8 bottoms; And solid phase can be cumulative on collecting bag.When running up to when a certain amount of, operating personnel open feed pipe 7 after closing down centrifuge, and collecting bag 5 is mentioned, and just the solid phase of collecting can be taken out, thereby finish the Separation of Solid and Liquid of mixed liquor.
