Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical precipitation, in particular to a pharmaceutical precipitation device. Background Art

[0002] During the pharmaceutical manufacturing process, liquid pharmaceuticals sometimes need to be precipitated to remove impurities (harmful or harmless) or to remove the precipitate for further processing. Conventional sedimentation tanks are often used, but extracting the supernatant can cause sediment that has already settled to the bottom of the tank to resurface. To avoid this, existing sedimentation devices use a filter press to accelerate the precipitation of the pharmaceutical liquid and separate the precipitate from the supernatant. This reduces disturbance of the precipitate during supernatant discharge, improving separation efficiency and quality. For example, a patent document with patent publication number CN218011591U discloses a biopharmaceutical precipitation device, which accelerates precipitation by an accelerating filter press, and then places the discharge pipe head near the liquid level and slowly descends with the liquid level, thereby reducing the disturbance of the sediment during the liquid separation process and improving the separation efficiency and quality. However, in this manner, the discharge pipe head is separately provided, and when the discharge pipe head is lowered below the accelerating filter press for drainage, the sediment will still be disturbed, and the accelerating filter press will cause blockage during use, requiring regular cleaning, which is inconvenient to use and makes the sedimentation device inefficient. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a pharmaceutical sedimentation device. By arranging a drainage hood on the upper side of the filter press plate, it can move up and down with the filter press plate, and completely discharge the clear liquid above the filter press plate without disturbing the sediment. The filter press plate can be cleaned by setting a cleaning brush to avoid clogging, thereby improving the utilization efficiency of the sedimentation device.

[0004] The top of the water pump is installed in the water pumping station, and the bottom of the water pump is installed in the water pumping station.

[0005] Furthermore, the lifting mechanism includes a screw rod rotatably arranged on the mounting frame and a first guide rod parallel to the screw rod, one end of the screw rod is fixed to the output end of the first rotating motor fixed on the mounting frame, and a screw rod nut is threadedly connected to the screw rod and slides with the first guide rod, and the screw rod nut is provided with a connecting block fixed to the hollow shaft.

[0006] Furthermore, the rotating mechanism includes a second rotating motor provided on the connecting block, an output end of the second rotating motor is fixed to a driving wheel, and the rotating ring is provided with gear teeth meshing with the driving wheel.

[0007] Furthermore, the mounting ring is provided with a second guide rod, and the rotating ring is provided with a guide hole that is slidably matched with the second guide rod.

[0008] Furthermore, a mounting groove is provided on the mounting rod, a support plate is movably provided in the mounting groove, a second elastic member is provided between the support plate and the top wall of the mounting groove, and the cleaning brush is fixed to the support plate by bolts.

[0009] Furthermore, a filter is provided in the seepage hole.

[0010] Furthermore, the feed port and the discharge port are both provided with normally closed valves.

[0011] The beneficial effects of the present invention are as follows: the feed port on the side wall of the tank body is used to inject the material to be precipitated into the tank body, and the discharge port at the bottom is used to discharge the precipitate. The hollow shaft is driven to rise and fall by a lifting mechanism, driving the filter press plate in the tank body to move up and down under the action of the hollow shaft, thereby accelerating the sedimentation speed and separating the clear liquid and the sediment after precipitation in the tank body. A drainage cover is fixed on the filter press plate, and the upper end of the drainage cover is fixed to the hollow shaft, so that the drainage cover is always located above the filter press plate and can move up and down with the hollow shaft, which can completely discharge the clear liquid above the filter press plate without disturbing the sediment below the filter press plate. The upper part of the hollow shaft is movably passed through the sealing cover and connected to the water pump through a hose. When the water pump is started, the clear liquid above the filter press plate is pumped out through the hollow shaft. A sleeve is movably provided on the hollow shaft, and a cleaning brush is supported on the sleeve by a mounting rod, and the cleaning brush can be used to clean the filter press plate. The upper end of the sleeve is fixed to the mounting ring, and the rotating ring is rotatably connected to the hollow shaft. A first elastic member is provided between the rotating ring and the mounting ring. The first elastic member causes the mounting ring to move downward, thereby allowing the cleaning brush to abut against the filter press plate through the sleeve while preventing the sleeve from excessively squeezing the drain cover and causing damage to the drain cover. When the rotating ring rotates under the drive of the rotating mechanism, the first elastic member drives the mounting ring to rotate, which in turn drives the sleeve to rotate. The sleeve drives the mounting rod to rotate, which in turn drives the cleaning brush to rotate circumferentially around the hollow shaft to clean the filter press plate. To sum up, by adopting the utility model, the hollow shaft is driven up and down by the lifting mechanism, which can drive the filter press plate to move up and down, accelerate the sedimentation efficiency, and drive the drainage cover to move up and down, and completely discharge the clear liquid above the filter press. By setting the filter press, the clear liquid and sediment in the tank body can be separated, avoiding the disturbance of the sediment below when the clear liquid is discharged from the drainage cover, thereby improving the separation efficiency of the sediment and the clear liquid. When the filter press needs to be cleaned, the cleaning brush can be driven by the rotating mechanism to rotate and brush the filter press, which is convenient for cleaning, avoids clogging of the filter press, and improves the utilization efficiency of the sedimentation device.

DETAILED DESCRIPTION

[0017] With reference to the accompanying drawings, specific embodiments of the present invention will be described in detail.

[0018] Reference Figures 1 to 3 The present invention provides a pharmaceutical precipitation device, comprising a tank body 1 and a cover 2 disposed above the tank body 1. The cover 2 is sealed against the tank body 1. A feed port 11 is provided on the side wall of the tank body 1 for injecting material to be precipitated into the tank body 1, and a discharge port 12 is provided at the bottom for discharging the precipitate. Furthermore, both the feed port 11 and the discharge port 12 are provided with normally closed valves to facilitate feeding and discharging of the tank body 1.

[0019] The tank body 1 is provided with a filter plate 3 having a plurality of seepage holes 31. Preferably, a filter screen is provided in the seepage holes 31 to improve the filter pressing effect. A drainage cover 41 is fixed to the filter plate 3 so that the drainage cover 41 is always located above the filter plate 3, and can completely drain the clear liquid above the filter plate 3 without disturbing the sediment below the filter plate 3. The upper end of the drainage cover 41 is fixed to the hollow shaft 4, and the upper end of the hollow shaft 4 is movably passed through the cover 2 and connected to the water pump 43 through a hose 42. When the water pump 43 is started, the clear liquid above the filter plate 3 is pumped out through the drainage cover 41 and the hollow shaft 4. The hollow shaft 4 is driven to rise and fall by a lifting mechanism 5 provided on a mounting frame 21. The mounting frame 21 is provided on the sealing cover 2. The hollow shaft 4 is driven to rise and fall by the lifting mechanism 5, driving the filter press plate 3 in the tank body 1 to move up and down under the action of the hollow shaft 4, thereby accelerating the sedimentation speed, and separating the clear liquid and the sediment after precipitation in the tank body 1, and driving the drainage cover 41 to move up and down, so that the clear liquid at different heights can be discharged.

[0020] Furthermore, the lifting mechanism 5 includes a screw rod 51 rotatably mounted on the mounting frame 21 and a first guide rod 52 parallel to the screw rod 51. One end of the screw rod 51 is fixed to the output end of a first rotary motor 53 fixed to the mounting frame 21. A screw nut 54 is threadedly connected to the screw rod 51 and slidably engaged with the first guide rod 52. The screw nut 54 is provided with a connecting block 55 fixed to the hollow shaft 4. At this time, the screw rod 51 is driven to rotate by the first rotary motor 53, and the first guide rod 52 stops the screw nut 54 from rotating, causing the screw nut 54 to move up and down on the screw rod 51, thereby driving the hollow shaft 4 to move up and down, thereby achieving up and down movement of the filter press plate 3.

[0021] A sleeve 6 is movably mounted on the hollow shaft 4. At least one mounting rod 61 is disposed on the outer side of the sleeve 6. Preferably, two mounting rods 61 are symmetrically arranged. A cleaning brush 62 is disposed on the mounting rod 61, which contacts the filter press plate 3 and can clean the filter press plate 3. Furthermore, the mounting rod 61 is provided with a mounting slot 611. A support plate 612 is movably mounted within the mounting slot 611. A second elastic member 613 is disposed between the support plate 612 and the top wall of the mounting slot 611. The cleaning brush 62 is secured to the support plate 612 via bolts. This arrangement allows the cleaning brush 62 to be detachable from the support plate 612, facilitating replacement. Furthermore, the second elastic member 613 further presses the cleaning brush 62 against the filter press plate 3, allowing the bristles of the cleaning brush 62 to clean the filter press plate 3 and improve cleaning efficiency.

[0022] The upper end of the sleeve 6 passes through the sealing cover 2 and is secured to a mounting ring 63. A rotating ring 64 is positioned above the mounting ring 63. The rotating ring 64 is rotatably connected to the hollow shaft 4 via a bearing. A first elastic member 65 is positioned between the rotating ring 64 and the mounting ring 63. The rotating ring 64 is driven to rotate by a rotating mechanism 7. The first elastic member 65 allows the mounting ring 63 to move downward, allowing the cleaning brush 62 to abut the filter press plate 3 through the sleeve 6. This prevents excessive squeezing of the sleeve 6 against the drain cover 41, ensuring flexible contact between the sleeve 6 and the drain cover 41 and preventing damage. When the rotating ring 64 rotates under the drive of the rotating mechanism 7, the first elastic member 65 drives the mounting ring 63 to rotate, which in turn drives the sleeve 6. The sleeve 6 then drives the mounting rod 61 to rotate, which in turn drives the cleaning brush 62 to rotate around the sleeve 6, cleaning the filter press plate 3.

[0023] Furthermore, the rotating mechanism 7 includes a second rotating motor 72 mounted on the connecting block 55. The output end of the second rotating motor 72 is fixed to the drive wheel 73, and the rotating ring 64 is provided with gear teeth 641 that mesh with the drive wheel 73. The connecting block 55 is fixed to the screw nut 54 and can move up and down synchronously with the screw nut 54, thereby maintaining the relative position of the gear teeth 641 and the drive wheel 73. When the second rotating motor 72 drives the drive wheel 73 to rotate, the drive wheel 73 drives the gear teeth 641, which in turn drives the rotating ring 64. This, in turn, drives the mounting ring 63 and the sleeve 6 via the first elastic member 65, thereby driving the cleaning brush 62 to rotate along the circumference of the hollow shaft 4 to clean the filter press plate 3. Furthermore, the mounting ring 63 is provided with a second guide rod 631, and the rotating ring 64 is provided with a guide hole 642 that slidably engages with the second guide rod 631. At this time, through the setting of the second guide rod 631, when the rotating ring 64 rotates, not only can the second guide rod 631 drive the sleeve 6 to rotate, but also guide the up and down movement of the mounting ring 63, thereby improving the structural stability between the mounting ring 63 and the rotating ring 64.

[0024] During use, the filter press plate 3 is raised to above the feed port 11 by the lifting mechanism 5. Material is then injected into the tank body 1 through the feed port 11. The lifting mechanism 5 then drives the filter press plate 3 up and down to accelerate sedimentation. After sedimentation is complete, the lifting mechanism 5 lowers the filter press plate 3 to the separation point between the sediment and the clear liquid. The water pump 43 is activated to pump the clear liquid above the filter press plate 3 through the drain cover 41 and the hollow shaft 4. The discharge port is then opened to discharge the sediment. When the filter press plate 3 screen needs to be cleaned, the cleaning brush 62 is rotated by the rotating mechanism 7 to clean the filter screen.

[0025] To sum up, by adopting the utility model, the hollow shaft 4 is driven up and down by the lifting mechanism 5, which can drive the filter press plate 3 to move up and down, thereby accelerating the sedimentation efficiency, and driving the drainage cover 41 to move up and down, so that the clear liquid above the filter press is completely discharged. By setting the filter press, the clear liquid and the sediment in the tank body 1 can be separated, and the clear liquid can be prevented from disturbing the sediment below when being discharged from the drainage cover 41, thereby improving the separation efficiency of the sediment and the clear liquid. When the filter press needs to be cleaned, the cleaning brush 62 can be driven by the rotating mechanism 7 to rotate and brush the filter press, which is convenient for cleaning, avoids clogging of the filter press, and improves the utilization efficiency of the sedimentation device.
