Detailed Description
The invention is further described with reference to the accompanying drawings and specific embodiments.
Fig. 1-3 show a single-axis pump configuration of a sedimentary disk centrifuge, wherein each of the three types of centrifuges has a mixed liquid inlet, a heavy liquid outlet, and a light liquid outlet. The centrifuge with the structure shown in fig. 1 is provided with a mixed liquid inlet 1, a heavy liquid outlet 5 and a light liquid outlet 6. This structural style's centrifuge adopts rotary drum centre of gyration feed liquor hole feed liquor, distributes around the rotary drum behind the bottom positioning disk, separates at the in-process that the mixed liquid upwards rises, and light liquid is removed the entering disc district to rotary drum centre of gyration after, receives self gravity to flow to the light liquid outlet and discharges the rotary drum system, and the light liquid outlet is isolated with mixed liquid, avoids polluting once more and collision. A light liquid flow passage is arranged below the rotary drum, and finally the light liquid leaves the centrifuge through a light liquid outlet 6, and the heavy liquid rises upwards along the wall of the rotary drum and enters a heavy liquid passage between the rotary drum and the baffle 3, then enters the centrifugal pump 4 and leaves the centrifuge. Solid particles move along the rotation center of the rotary drum in the opposite direction and settle in the slag containing area of the rotary drum, and the centrifuge can be detached regularly for cleaning. However, the centrifugal machine with the structure has the following defects: firstly, the structure of the chassis for mounting the rotary drum and the disc is relatively complex, the liquid outlet of the light liquid is also near the rotary drum rotation center, the mixed liquid is redistributed and enters the rotary drum after being fed by the liquid inlet pipe of the rotary drum rotation center, the centrifugal machine with the structure needs to ensure that the mixed liquid and the light liquid are not subjected to encounter any more after separation and are mixed, and the structure is complex. Secondly, in the actual use process, because some mixed liquid can be mixed with cotton products and fibers exist, the connection between the light liquid outlet hole and the disc base plate and the rotary drum can cause blockage, the cleaning is inconvenient, and the adaptability to the mixed liquid is poor. Meanwhile, the centrifuge with the structure only has one separation process, namely, the mixed liquid only rises upwards in the separation process, so that the separation efficiency is low.
The centrifuge of the configuration shown in fig. 2 has a mixed liquid inlet 1, a heavy liquid outlet 2 and a light liquid outlet 3. The centrifuge of this structure only has a centripetal pump, draws heavy liquid and discharges centrifuge through the centripetal pump, and light liquid then flows centrifuge according to self gravity, and the runner is comparatively complicated. The working principle is that mixed liquid enters the diverter valve through the liquid inlet 1 and then enters the centripetal pump and then enters the heavy liquid distribution chamber, the heavy liquid distribution chamber is formed by assembling a rotary drum and a top distribution disc, the top distribution disc is provided with a liquid inlet hole, and the top distribution disc is provided with a liquid inlet baffle plate and a guide plate. The mixed liquid is guided into the liquid inlet hole through the baffle plate and the guide plate, the liquid inlet hole corresponds to the liquid inlet holes of the disc pressing plate and the disc below one by one, and the mixed liquid entering the liquid inlet hole starts to be separated and purified. The light liquid moves towards the rotary center of the rotary drum along the disc, enters the light liquid outlet flow passage and finally is discharged out of the equipment through the liquid outlet 3. Heavy liquid moves along the disc in the opposite direction to the rotation center of the rotary drum and leaves the disc area, finally enters the chamber of the centrifugal pump through the chamber between the top distribution disc and the disc pressing disc, is extracted by the centrifugal pump and leaves the centrifuge through the heavy liquid outlet 2. The solid particles move along the disc in the reverse direction towards the rotation center of the rotary drum and settle in the slag containing area of the rotary drum, and the centrifuge can be periodically opened to manually remove the solid particles. In the centrifuge with the structure, the mixed liquid enters the centrifuge through the rotary drum and the top distribution disc, the disc pressing disc and the liquid inlet hole of the disc and is separated, and the heavy liquid leaves the rotary drum through the heavy liquid outlet cavity between the top distribution disc and the disc pressing disc and enters the centrifuge system, under the condition, the mixed liquid and the purified heavy liquid meet and are mixed again, so that the separation effect and the separation efficiency are reduced, and meanwhile, the mixed liquid and the heavy liquid generate convection collision and generate turbulence to cause larger equipment vibration; the light liquid only uses the self gravity, and the liquid outlet speed is slow due to the complex flow passage structure; meanwhile, according to market research, most of mixed liquid may contain fiber substances, and in the liquid inlet system of the centrifuge with the structure, the fiber substances are accumulated around the liquid inlet holes of the top distribution disc, the disc pressing disc and the disc, so that unsmooth liquid inlet of the mixed liquid is caused after a long time, the separation efficiency is reduced, even a flow channel is blocked, a machine cannot run, the cleaning difficulty is high, and the requirement on operators is high. Meanwhile, the centrifuge with the structure only has one separation process, and because the blanking hole is close to the edge of the disc, when the mixed liquid is not fully separated, the heavy liquid begins to climb upwards along the wall of the rotary drum, so that the separation efficiency is low.
The centrifuge of the structure shown in fig. 3 has a mixed liquid inlet, a heavy liquid outlet and a light liquid outlet. The centrifugal machine with the structure uses a heavy liquid centripetal pump, light liquid is discharged from a light liquid outlet, the light liquid is discharged out of the centrifugal machine by utilizing the gravity and the centrifugal force of the centrifugal machine, and solid particles are settled in a slag containing area of the rotary drum and can be manually cleaned regularly. The operation principle of the centrifuge with the structure is as follows: the mixed liquor enters a central blanking hole of the centripetal pump through a feeding pipe and then enters a mandrel bin, the mixed liquor flows to a feeding gap formed between a top end disc and a distribution disc from the mandrel bin, the distribution disc is provided with blanking holes, the discs below the distribution disc are also provided with blanking holes, all the blanking holes are in one-to-one correspondence, the mixed liquor finally enters the blanking holes of a disc area for separation, the separated heavy liquor ascends along the drum wall of the rotary drum and enters a discharging gap between the top end disc and the rotary drum, then enters an annular heavy liquor discharging hole of the centripetal pump and then enters a heavy liquor discharging pipe and is discharged out of the centrifugal machine; the light liquid moves along the disc towards the direction of the rotary axis and enters a light liquid discharge port, and is discharged out of the centrifuge by means of the gravity and the centrifugal force of the light liquid; the solid particles are settled in a slag containing area of the rotary drum, and the machine is periodically opened for cleaning. In the use process of the centrifuge with the structure, due to the existence of fiber substances in the mixed liquid, the fiber substances can be accumulated around the blanking hole, the liquid inlet of the mixed liquid is not smooth after a long time, the separation efficiency is reduced, even the flow channel is blocked, the centrifuge cannot run, the cleaning difficulty is high, and the requirement on operators is high. Meanwhile, the centrifuge with the structure only has one separation process, and because the blanking hole is close to the edge of the disc, when the mixed liquid is not fully separated, the heavy liquid begins to climb upwards along the wall of the rotary drum, so that the separation efficiency is low.
Fig. 4 shows a two-way centrifugal pump centrifuge, which has a mixed liquid inlet 201, a light liquid outlet 220, and a heavy liquid outlet 221. The working principle of the centrifuge with the structure is that sealing water is firstly filled in a 206 sealing water gap, after a certain proportion of sealing water enters, a mixed liquid inlet 201 starts to feed mixed liquid into the centrifuge, the mixed liquid flows to the bottom end of a disc through a liquid inlet central tube and flows to the wall of a rotary drum, when the mixed liquid starts to rise, the mixed liquid starts to separate, light liquid flows to the rotary center of the rotary drum along the disc and slowly rises, and the light liquid enters a light liquid centripetal pump and then leaves the centrifuge through a light liquid outlet 220. Heavy liquid moves in the direction opposite to the rotation center of the rotary drum and climbs along the drum wall to enter a channel between the I and the rotary drum, then enters the heavy liquid centripetal pump and then leaves the centrifuge through a heavy liquid outlet 221; solid particles settle in the region H; this centrifuge's rotary drum is split type structure, the lower half rotary drum is after giving out sealing water, lower rotary drum descends, the particulate matter of subsiding in regional H is discharged by row cinder notch L, 206 sealing water inlet begins the water injection simultaneously, the effect of water injection is inside cleaning centrifuge this moment, ensure the inside cleanness of centrifuge, then lower rotary drum reinjects sealing water and lifting, it is sealed with last rotary drum combination once more, stop the water injection after sealing water injection port pours into sealing water into, mixed liquid inlet 201 begins to pour into mixed liquid and separates, cycle work carries out in proper order. The centrifuge of this structure does not need the manual work to clear up solid particle thing, and degree of automation is high, generally is suitable for the flow big, long-time continuous operation, long-term unmanned on duty's workplace. However, the centrifugal machine with the structure is complex in overall structure, a large amount of mixed liquid and cleaning water (sealing water) are discharged simultaneously when solid particles are discharged, the water content is high, the weight of the equipment is large, the size is large, and a water supply tank and a pipeline system of the sealing water are required to be matched, so that the centrifugal machine is generally not suitable for a mobile working scene.
FIG. 5 is a schematic view of an embodiment of the inner flow passage of the single-centripetal centrifuge according to the present invention, showing the flow of the mixed liquid, light liquid and heavy liquid and the configuration of the discs in the disc zone.
The working principle and flow of the present invention according to this embodiment will now be described as follows:
the mixed liquor enters a central liquor inlet hole of the inlet and outlet liquid diverter valve from a mixed liquor inlet 1, passes through a secondary liquor inlet hole of the heavy liquor centripetal pump, then reaches an area mixed liquor buffer chamber 15 (composed of a specific gravity ring and a disc fixing disc), then enters a liquor inlet chamber formed between the specific gravity rings 8 and 9, and then enters the rotary drum system.
The motor drives the drum system to rotate at high speed as a whole, and as shown in the figure, the drum system comprises a jet pipe 6, a drum wall 7, a specific gravity ring 8, a disc fixing disc 9, a flow guide structure 10, a sedimentation disc area 11, a light liquid outlet 12 (located in the drum), a light liquid guide disc 14 and a mixed liquid buffer chamber 15, which all rotate at high speed.
After the mixed liquid reaches the regional diversion structure 10, the mixed liquid flows downwards along the direction indicated by the arrow, and simultaneously separation is started, light liquid moves towards the rotation center direction of the rotary drum along the disc area (if the content of the light liquid in the mixed liquid is low, when separation is started, heavy liquid also appears in the disc area, the reason why the light liquid outlet is close to the rotation center is to avoid that the heavy liquid possibly flows out along the light liquid outlet along with the light liquid) and enters the light liquid accumulation area, when the light liquid is accumulated at the light liquid outlet on the disc chassis, the light liquid can be smoothly discharged out of the rotary drum system to the light liquid guide disc by using centrifugal force, and then leaves the centrifuge through the light liquid outlet 3. The heavy liquid moves to the rotary center of the rotary drum in the opposite direction and moves to a slag containing area of the rotary drum.
In the process of downward movement of the mixed liquor, the mixed liquor is also separated for the first time, part of heavy liquor reaches a slag containing area of the rotary drum, light liquor enters a sedimentation disc area 11, the mixed liquor after the first separation starts to climb upwards along the wall of the rotary drum after reaching the bottom of the rotary drum, and in the process, the mixed liquor starts to enter the second separation; as shown in the figure, after the first separation, the content of light liquid and solid particles in the mixed liquid becomes very small, and when the second separation is performed, the contained light liquid moves to the rotation center of the rotary drum, and collides with the heavy liquid in the mixed liquid for the first separation, and enters the mixed liquid for the first separation again or enters the disc, so that a U-shaped circulation process is performed.
The heavy liquid after the secondary separation enters the jet pipe 6 through a liquid outlet channel between the rotary drum wall 7 and the specific gravity ring 8 and then is jetted out, then enters the arc-shaped flow channel 5, then enters the peripheral heavy liquid flow channel 4, finally enters the inlet and outlet liquid diverter valve and then leaves the centrifuge through the heavy liquid outlet 2.
In the area of the flow guide structure 10, the tail ends of the specific gravity ring 8 and the disc fixed disc 9 are provided with flow guide baffles to ensure the flow direction of the mixed liquid; the specific gravity ring 8 extends to the drum wall in the horizontal direction by a section at the tail end.
The extension of the specific gravity ring 8 to the drum wall in the horizontal direction is to ensure that purer heavy liquid can enter a liquid outlet flow channel between the drum wall 7 and the specific gravity ring 8.
As shown in FIG. 5, the upper surface of the disc in the area of the sedimentation disc area 11 is provided with a salient point for stabilizing the flow and reducing the influence of the Coriolis force, and when the salient point contains heavy liquid and light liquid simultaneously in the disc area, the relative motion collision between the fluids can be effectively reduced, and the influence of the Coriolis force on the light liquid can be reduced.
The invention provides an internal flow passage of a centrifugal machine with a one-way centrifugal pump and a disc structure thereof, wherein a liquid inlet/outlet diverter valve is connected and sealed with a middle secondary liquid inlet hole of a heavy liquid centrifugal pump and is directly connected to a chamber formed by assembling a specific gravity ring and a disc fixed disc, devices such as a blanking hole, a blanking baffle plate, a guide plate and the like are reduced on the disc fixed disc, the manufacturing cost can be reduced in the manufacturing process, and simultaneously (due to frequent mixing of fiber substances in mixed liquid, the substances are very easy to deposit on the blanking hole, the blanking baffle plate and the guide plate to cause blockage, if the liquid inlet form of figures 2 and 3 is adopted, the blanking hole on the disc is also blocked) can be effectively prevented from being blocked by the fiber substances. The distance between the light liquid outlet and the revolving center of the rotary drum is short, so that the content of heavy liquid in the light liquid is lower; the mixed liquid guide plates are arranged at the tail ends of the specific gravity ring and the disc fixing disc, so that the mixed liquid can flow downwards along the edge of the disc and climb upwards along the wall of the rotary drum after reaching the bottom to form a circular flow action, the flowing time of the mixed liquid in the rotary drum is prolonged, the separation time is prolonged, and the separation and purification can be carried out more effectively; the light liquid guide disc can effectively relieve the speed factor of light liquid when the light liquid goes out, and meanwhile, the motor can be protected from being polluted by the light liquid to cause the failure of the motor.
The mixed liquor begins to be separated for the first time in the downward process, light liquor can move towards the rotation center of the rotary drum and enter a sedimentation disc area, heavy liquor can move towards the wall of the rotary drum, and solid particles can also move towards the wall of the rotary drum and settle in a slag containing area of the rotary drum; when the mixed liquid moves downwards and then upwards along the drum wall, the second separation is carried out, and the mixed liquid contains few light liquid and solid particles due to the first separation, so that the mixed liquid meets the heavy liquid and the solid particles which are separated from the mixed liquid for the first time during the second separation, but the collision in the process can be ignored and ignored because the mixed liquid which is separated for the second time is already equal to the heavy liquid in the figures 1, 2 and 3, and the circulating purification effect can be achieved.
The fixed mounting holes are formed in the discs in the sedimentation disc area, the metal rods with the same diameter penetrate through the holes, all the discs are fixed by the metal rods, relative rotation with other parts is avoided, the disc is only assembled, and the disc does not participate in separation work when the whole machine is used.
It should be noted that the above-mentioned embodiments provided by the present invention are only illustrative, and do not limit the scope of the specific implementation of the present invention. The scope of the invention is intended to include such modifications or alterations as would be obvious to one of ordinary skill in the art.
