Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a centrifuge for separating acetaminophen mother liquor. Background Art

[0002] Centrifuges are commonly used in chemical production to separate solid particles from liquids in suspensions, or to separate two immiscible liquids of different densities in emulsions. Because acetaminophen mother liquor contains a mixture of mother liquor and crystals, the separation of mother liquor and crystals directly impacts product yield and mother liquor reuse. Therefore, centrifuges are typically used to separate acetaminophen mother liquor, using the centrifugal force generated by the centrifuge to separate the crystals from the mother liquor.

[0003] A centrifuge for separating acetaminophen mother liquor in the prior art is currently inconvenient to clean after use. The centrifugal filter barrel of the centrifuge is difficult to clean, and acetaminophen crystals may remain on the centrifugal filter barrel, which will affect the next centrifugal filtration. The existing cleaning method is to remove the centrifugal filter barrel as a whole for cleaning. This cleaning method is very inefficient and requires constant installation and removal of the filter barrel, which is less practical. In addition, the centrifuge for separating acetaminophen mother liquor in the prior art does not have a shock-absorbing structure during operation. Due to the rotation of the filter barrel, the entire barrel body may shake, which is very unstable. Utility Model Content

[0022] The effect achieved by the entire embodiment 1 is that acetaminophen is poured into the feed pipe 7. At this time, the operation of the first motor 4 drives the support plate 5 to rotate, thereby driving the filter frame 6 and the filter plate 10 to rotate, so that the acetaminophen in the filter frame 6 is centrifuged, and the solid particles are left in the filter frame 6 and the filter plate 10. By opening the control valve 18, qualified acetaminophen is discharged from the discharge pipe 17. Through the setting of the shock-absorbing structure 21, when the device vibrates during operation, the shock-absorbing structure 21 can perform shock-absorbing treatment on the entire device to prevent it from shaking, displacement or collapse, and the stability is stronger.

[0023] Example 2, as Figure 1-4 As shown, the shock absorbing structure 21 includes a spring 2101 fixed on the inner top wall of the pillar 19, a movable column 2102 is fixed to the bottom end of the spring 2101, the bottom end of the movable column 2102 passes through the bottom end of the pillar 19 and is fixed to the bottom plate 20, a damper 2103 is installed on the inner side of the spring 2101 between the movable column 2102 and the inner top wall of the pillar 19, a connecting pipe 12 is installed in the top cover 2, a plurality of high-pressure nozzles 13 are installed on the outer wall of the connecting pipe 12, a connecting pipe 14 is fixed to the top end of the connecting pipe 12, the top end of the connecting pipe 14 passes through the top cover 2 and is provided at Outside the top cover 2, an inner cavity 11 is opened at the bottom end of the top cover 2, and a connecting pipe 12 is installed in the inner cavity 11. A flange 15 is fixed to the outer wall of one end of the connecting pipe 14 located outside the top cover 2. A guide plate 16 is fixed on the inner bottom wall of the barrel body 1, and a discharge pipe 17 is arranged at the guide port of the guide plate 16. A second motor 8 is installed in the filter frame 6, and a connecting column 9 is fixed to the output end of the second motor 8. The filter plate 10 is fixed to the connecting column 9. A bracket 3 is fixed to the top of the top cover 2, and the first motor 4 is installed at the bottom end of the bracket 3. Feed pipes 7 are fixed on both sides of the first motor 4 in the top cover 2.

[0024] The effect achieved by the entire embodiment 2 is that after the filter frame 6 and the filter plate 10 rotate to separate the acetaminophen mother liquor, the connecting pipe 14 is connected to the external water outlet device by the setting of the flange 15. After the connection is good, the external water source circulates through the connecting pipe 14 and the communicating pipe 12, and is sprayed by the high-pressure nozzle 13 to flush the filter frame 6 and the filter plate 10. After flushing, the operation of the second motor 8 drives the connecting column 9 to rotate, thereby driving the filter plate 10 to rotate, so that the filter plate 10 is vertically placed in the filter frame 6. At this time, the flushed solid particles will directly fall and be discharged, achieving the effect of cleaning the filter frame 6 and the filter plate 10.

By the setting of the spring 2101 and the damper 2103, when the barrel 1 vibrates, the operation of the spring 2101 and the damper 2103 can be used to damp the device as a whole, avoiding the phenomenon of shaking and displacement or collapse, and having stronger stability.

[0025] Working principle: When the device is used, acetaminophen is poured into the filter through the feed pipe 7. At this time, the operation of the first motor 4 drives the support plate 5 to rotate, thereby driving the filter frame 6 and the filter plate 10 to rotate, so that the acetaminophen in the filter frame 6 is centrifuged, and the solid particles are left in the filter frame 6 and the filter plate 10. By opening the control valve 18, the qualified acetaminophen is discharged from the discharge pipe 17. After separation, when the filter frame 6 and the filter plate 10 rotate to separate the acetaminophen mother liquor, the flange 15 is set to connect the connecting pipe 14 to the external water outlet device. After the connection is completed, the external water source flows through the connecting pipe 14 and the connecting pipe 12, and is sprayed out through the high-pressure nozzle 13 to flush the filter frame 6 and the filter plate 10. After flushing, the second motor 8 is operated to drive the connecting column 9 to rotate, thereby driving the filter plate 10 to rotate, so that the filter plate 10 is placed vertically in the filter frame 6. At this time, the flushed solid particles will fall and be discharged directly. When the barrel body 1 vibrates, the operation of the spring 2101 and the damper 2103 can perform shock absorption treatment on the entire device to prevent it from shaking, displacement or collapse.
