[0002] Pharmaceutical salts are a kind of bulk pharmaceutical chemicals with a large consumption in the medical and health industry and belong to the deep processing products of salts. Pharmaceutical sodium chloride is mainly used for large volume infusions, and secondly, together with pharmaceutical potassium chloride, pharmaceutical magnesium chloride, and pharmaceutical calcium chloride, it forms products for dialysis. There has been a production history of many years in China. Currently, in the production process, separation is an important step. Separating impurities from pure products and separating solids from liquids both require the help of separation devices.
[0003] Currently, the separation devices in pharmaceutical salt production have disadvantages such as low discharging efficiency, high material humidity, large blanking inertia, wall sticking, and caking, resulting in problems such as decreased product quality, high energy consumption, and low production efficiency.
[0004] In addition, the current separation devices in pharmaceutical salt production also have the following problems:
[0005] 1. The discharging port is too large, with poor selectivity, and it cannot effectively screen out some materials with poor dehydration effect. The overall humidity of the materials cannot reach the optimal state, and the wet materials with high water content will affect the subsequent drying effect and drying efficiency.
[0006] 2. The wet materials have high moisture content and poor fluidity, and the materials are prone to phenomena such as wall sticking at the blanking port, and it is necessary to clean the discharging port regularly; a large amount of massive materials enter the subsequent processing steps, affecting the drying efficiency of the products and further affecting the product quality.
[0007] Therefore, based on the above problems, designing a new separation device for pharmaceutical salt production is an urgent technical problem in this field. Summary of the Utility Model
[0008] The utility model provides a separation device for pharmaceutical salt production to solve the problems existing in the above-mentioned prior art.
[0009] The technical solution adopted by the utility model to solve this problem is:

The present invention will be specifically described below with reference to the drawings.
[0042] Embodiment 1:
[0043] A separation device for the production of medicinal salts, comprising a device housing 1, a housing cover 2, and a separation space therebetween. The housing cover 2 can be installed at the open end of the device housing 1 through bolt assemblies. The separation space is divided into a drum separation area A and a discharging area B by an annular partition 3, wherein:
[0044] A drum structure 4 is rotatably provided within the drum separation area A. One side of the drum structure 4 facing the discharge area is an open end, and the side facing away from the discharge area is a closed drive end.
[0045] The bottom wall of the discharge area B is provided with a sloped bottom 5 having a certain slope. A dry material outlet 6 is provided at the high position of the sloped bottom 5, and a wet material outlet 7 is provided at the low position. A dry material pipe 8 is inserted into the dry material outlet 7. One end of the dry material pipe 8 is welded through the annular partition 3, and the other end extends out of the dry material outlet 6.
[0046] An inlet structure 9 is further provided on the outer shell cover 2. One end of the inlet structure 9 passes through the annular partition 3 and extends into the drum structure 4 and is connected to the inlet distributor 10, and the other end extends out of the outer shell cover 2.
[0047] In this embodiment, the device housing 1 and the outer shell cover 2 enclose a separation space, and the separation space is separated into a drum separation area A and a discharge area B by the annular partition 3. Feed is introduced into the drum structure 4 through the inlet structure 9. When the drum structure 4 in the drum separation area A rotates, solid-liquid separation of the medicinal salt can be achieved under the action of centrifugal force. Among them: the dry material outlet 6 and the dry material pipe 8 are outlets for dry material substances, and the dry material substances after solid-liquid separation are transported out from here and then transported to the dryer. The wet material outlet 7 is an outlet for wet material substances, and the wet material substances generated under the continuous action of centrifugal force are discharged through this port. The bottom wall of the discharge area B is set as a sloped bottom 5 having a certain slope (preferably, the slope is between 5° and 30°), which can enrich the wet material with a higher water content, and a wet material outlet 7 is provided at an appropriate position (low place), and finally the remaining wet material can be transported out and refluxed to the mother liquor.
[0048] Through the improvement of the above-mentioned dry material outlet and wet material outlet, on the one hand, effective separation of wet materials with poor flowability due to high water content can be achieved, reducing the phenomenon of material hanging on the discharge port and reducing the frequency of cleaning the discharge port; on the other hand, the appearance frequency of blocky materials is significantly reduced, from the original 10% to 3%, improving the processing capacity of subsequent steps.
[0049] It should be noted that: according to the adjustment of multiple parameters and actual monitoring of this device, the concentrated discharge position of the wet material after separation is found. Setting the bottom wall of the discharge area B as a sloped bottom helps to enrich the wet material, and then the most suitable discharge range is selected according to the most suitable feed amount, and the position and size of the dry material outlet are selected. By changing the position and size of the dry material outlet and the wet material outlet, this device improves the problems of the original discharge port being too large and having poor selectivity. After improvement, 90% of the dry materials with appropriate humidity are discharged from the dry material outlet, improving the material humidity, improving the product quality, and saving the time and energy required for subsequent processing processes.
[0050] Further, it can also be considered in this embodiment that the inner diameter dimension of the annular partition 3 is smaller than the inner diameter dimension of the open end of the drum structure 4, and the axes of the annular partition 3 and the drum structure 4 coincide.
[0051] Further, it can also be considered in this embodiment that the drum structure 4 is a stepped hollow columnar structure with an increasingly expanding inner diameter towards the opening direction, including at least two levels of stepped drums. Taking this embodiment as an example, it includes a first-level drum 401 and a second-level drum 402, and the inner diameter of the second-level drum 402 is larger than that of the first-level drum 401.
[0052] Further, it can also be considered in this embodiment that the driving end of the drum structure 4 is connected to the driving component through a linkage shaft 11. The axes of each level of the stepped drums and the linkage shaft 11 are coaxial. The driving component can be but is not limited to a motor component or a hydraulic component, which provides a power source for the centrifugal rotation of the drum structure 4 and generates a strong centrifugal force. Taking this embodiment as an example, the axes of the first-level drum, the second-level drum, and the linkage shaft coincide. When the drum structure 4 rotates at a set high speed and continuously rotates axially, it drives the first-level drum and the second-level drum to rotate, and the solid-liquid separation effect of the medicinal salt can be achieved under the continuous action of the centrifugal force.
[0053] Further, it can also be considered in this embodiment that the feeding structure 9 includes an integrally connected vertical section, a large-angle inclined section, and a small-angle inclined section. The small-angle inclined section is connected to the feeding distributor 10. The discharging end of the feeding distributor 10 is close to the closed end of the drum structure 4 and is parallel to it. One end of the feeding structure 9 is communicated with the feeding distributor, and the other end is communicated with a cooling crystallizer (not shown in the figure). The feeding structure 9 plays a role in transporting and distributing the material flow direction, and can feed while the drum structure 4 rotates, realizing a separation method that combines centrifugal rotation and continuous feeding.

[0055] Embodiment 2 of the present utility model is further improved on the basis of Embodiment 1 in order to fully exert the technical advantages of the present invention. The following is an illustrative description of this.
[0056] For example: A separation disk 12 is provided at the closed end of the drum structure 4. A convex structure 13 is provided on the side of the separation disk 12 facing the feeding distributor 10. The convex structure 13 includes a number of S-shaped protrusions arranged in an annular array. When the drum structure 4 rotates, the S-shaped protrusions rotate accordingly, playing a role in assisting separation.
[0057] Further, it can also be considered in Embodiment 1 / 2 that control valves are provided on the dry material outlet 6 and the wet material outlet 7.
[0058] Further, it can also be considered in Embodiment 1 / 2 that an observation window 14 is provided on the outer shell cover 2. Through holes are evenly distributed on the observation window 14. One side of the observation window 14 is connected with a closing door 15 through a hinge. The closing door 15 and the observation window 14 are locked to each other through a locking member (not shown in the figure). The interior of the separation device can be observed by opening the closing door 15, which is convenient for operation.
[0059] Further, it can also be considered in Embodiment 1 / 2 that a cleaning structure is provided on the outer shell cover 2. The cleaning structure includes a plurality of cleaning pipes 16. One end of the cleaning pipe 16 is a liquid outlet end that passes through the annular partition 3 and extends into the drum structure 4, and the other end is a joint end that extends out of the outer shell cover 2. When there are requirements for the purity of the separated substance, cleaning liquid can be sprayed into the drum structure 4 through the cleaning pipes 16, and the cleaning liquid is continuously sprayed onto the solid filter cake, achieving the effect of reducing the content of solid impurities.
[0060] Further, it can also be considered in Embodiment 1 / 2 that the cleaning pipe 16 is of a straight pipe structure, and the liquid outlet end of the cleaning pipe 16 is in the shape of a main pipe or an arc-shaped pipe.
[0061] Embodiment 3:
[0062] Embodiment 3 of the present utility model is further improved on the basis of Embodiment 1 or 2 in order to fully exert the technical advantages of the present invention. An illustrative description will be given below.
[0063] For example: when the liquid outlet end of the cleaning pipe 16 is in the shape of an arc-shaped pipe, the liquid outlet directions of the liquid outlet ends of the cleaning pipes 16 are different. Taking this embodiment as an example, the cleaning structure includes four cleaning pipes 16, and the liquid outlet ends of the four cleaning pipes 16 can be respectively directed upward, downward, left, and right directions, realizing the spraying of the cleaning liquid in multiple directions, which helps to further reduce the content of solid impurities.
[0064] The above embodiments have described the present utility model in detail, but the above content is only the preferred embodiment of the present utility model and cannot be considered as limiting the implementation scope of the present utility model. Any equal changes and improvements made within the scope of the application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
