Description

Technical Field

[0001] This utility model relates to the field of active pharmaceutical ingredient (API) production technology, specifically to a magnetic impurity removal device used in the drying process of API production. Background Technology

[0002] Taking the production of potassium chloride raw materials as an example, the production process involves dissolving and refining, filtering, concentrating, cooling and crystallizing, centrifuging, drying, mixing, inner packaging, and outer packaging.

[0003] The drying process involves starting the blower, cooler, and induced draft fan; opening the steam valve of the heater for preheating; and adding the wet potassium chloride product through the vibrating fluidized bed feed inlet for drying when the inlet temperature reaches the required level. The product exiting the vibrating fluidized bed should have a flowing, sand-like appearance, free of lumps, and should not clump together when squeezed, crumbling easily when released. The intermediate product from the vibrating fluidized bed is then collected in a transfer container, weighed, and transferred to…

[0004] Next step.

[0005] The entire vibrating fluidized bed is supported on a base by springs. The perforated plate is slightly tilted towards the discharge end, and a vibrating motor is installed on one or both sides of the machine body. The material is fluidized by the combined action of mechanical vibration and perforated airflow, and moves forward under the action of vibration.

[0006] This machine uses a vibrating motor to generate excitation force, causing the material to jump and move forward under the action of the excitation force in a given direction. Simultaneously, hot air input from under the bed fluidizes the material, ensuring full contact between the material particles and the hot air, thus achieving the desired effect. The material enters the machine through the feed inlet and, under the action of vibration, is thrown forward continuously in a horizontal direction. Hot air rises through the fluidized bed and exchanges heat with the wet material. The humid air is then discharged through the exhaust port after being dusted by a cyclone separator, while the dried material is discharged through the discharge port.

[0007] Due to limitations in technology and equipment, the intermediate product after drying has quality problems such as black slag and foreign matter, which affects the quality of the product. Analysis shows that the black slag and foreign matter are mainly magnetic impurities inherent in the material itself and metal impurities that may be introduced from the equipment.

[0008] How to efficiently remove these magnetic impurities is a problem that urgently needs to be solved in the field of active pharmaceutical ingredient (API) production. Utility Model Content

[0035] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0036] Example 1

[0037] like Figures 1-3 As shown, Example 1 provides a magnetic impurity removal device for the drying process of active pharmaceutical ingredient production, including a magnetic separator 100, which is installed at the discharge port of a vibrating fluidized bed.

[0038] The magnetic separator 100 includes a housing 110 and a magnetic separation layer 120.

[0039] The upper end of the outer shell 110 is provided with a feed inlet 111, which is used to connect with the discharge port of the vibrating fluidized bed. The lower end of the outer shell 110 is provided with a discharge port 112. Several grooves 113 extending into the interior are provided on the front side of the outer shell 110.

[0040] The magnetic separation layer 120 corresponds one-to-one with the slide groove 113. The magnetic separation layer 120 includes an outer frame 121 and a number of magnetic rods 122 spaced apart in the outer frame 121. The outer frame 121 can slide into or out of the outer shell 110 along the slide groove 113.

[0041] This application installs a magnetic separator 100 at the discharge port of a vibrating fluidized bed. After the product is dried by the vibrating fluidized bed, it enters the magnetic separator 100. Magnetic impurities in the product are adsorbed onto the magnetic rods 122, while the pure product is discharged from the discharge port 112 of the magnetic separator 100. Therefore, this application can effectively remove magnetic impurities from the product, which not only reduces the potential impact of impurities on the quality of potassium chloride products, but also improves the overall effect of product processing, providing a purer quality foundation for subsequent production steps, and creating favorable conditions for the smooth progress of the entire production process and the improvement of the final product quality. When the magnetic impurities adsorbed on the magnetic rods 122 of each magnetic separation layer 120 reach a certain amount, each magnetic separation layer 120 can be extracted from the outer shell 110, and then the magnetic impurities adsorbed on the magnetic rods 122 can be cleaned. After cleaning, each magnetic separation layer 120 can be loaded into the corresponding chute 113.

[0042] In some embodiments, refer to Figure 2 and Figure 3The front side of the outer shell 110 is provided with two opposing sliding grooves 113. The magnetic separation layer 120 installed in the upper sliding groove 113 has N (N is an even number) magnetic rods 122, and the magnetic separation layer 120 installed in the lower sliding groove 113 has N-1 magnetic rods 122. The magnetic rods 122 of the upper and lower layers are parallel to each other, and the magnetic rods 122 of the lower layer are arranged one-to-one below the magnetic rods 122 of the upper layer.

[0043] Optionally, the number of magnetic rods 122 in the upper layer is four, and the number of magnetic rods 122 in the lower layer is three.

[0044] By setting two magnetic separation layers 120, with the magnetic rods 122 of the upper and lower magnetic separation layers 120 arranged alternately, it can be ensured that the magnetic impurities in the product are in full contact with the magnetic rods 122 in the magnetic separator 100, thereby improving the effect of the magnetic separator 100 in removing magnetic impurities from the product.

[0045] In some embodiments, refer to Figure 1 To facilitate the pulling of the magnetic separation layer 120, each magnetic separation layer 120 has a handle 123 on the front side of its outer frame 121.

[0046] In some embodiments, refer to Figure 1 Each magnetic separation layer 120 has a locking member 130 on both sides. The locking member 130 includes a latch 131 and a hook 132. The latch 131 is installed on the outside of the outer shell 110, and the hook 132 is installed on the outside of the front part of the outer frame 121 for connecting with the latch 131. After the magnetic separation layer 120 is pushed into each slide groove 113, the latches 131 on both sides of the outer shell 110 can be locked with the hooks 132 on both sides of the magnetic separation layer 120, thereby locking the magnetic separation layer 120 inside the outer shell 110.

[0047] Optionally, the latch 131 includes a hinge seat 1311, a locking arm 1312, and a U-shaped rod 1313. The hinge seat 1311 is fixed to the outside of the housing 110. The front end of the locking arm 1312 is hinged to the hinge seat 1311, and a vertical pivot 1314 is provided in the middle of the locking arm 1312. Both ends of the U-shaped rod 1313 are fixed to the vertical pivot 1314, and the bent part of the U-shaped rod 1313 is used to hook onto the locking hook 132. When locking, the U-shaped rod 1313 is hooked onto the locking hook 132, and then the locking arm 1312 is pressed against the housing 110 side, so that the locking arm 1312 pulls the U-shaped rod 1313 tight. When unlocking, the locking arm 1312 is pulled outward, and the locking arm 1312 releases the U-shaped rod 1313, so that the U-shaped rod 1313 disengages from the locking hook 132.

[0048] Optionally, to facilitate the installation of the locking hook 132, the front sides of the outer frame 121 of the magnetic separation layer 120 are provided with side plates 1211 that bend backward outside the outer shell 110, and the locking hook 132 is fixed to the outside of the side plates 1211.

[0049] In some embodiments, a sealing gasket 1212 is provided between the front part of the outer frame 121 and the outer shell 110, which can improve the sealing between the magnetic separation layer 120 and the outer shell 110 and prevent material from leaking out between the outer frame 121 and the outer shell 110.

[0050] Example 2

[0051] like Figure 4 As shown, Embodiment 2 provides a magnetic impurity removal device for the drying process of raw material drug production, which also includes a vibrating screen 200, which is located below the discharge port of the vibrating fluidized bed, and the feed port 111 of the magnetic separator 100 is connected to the discharge port of the vibrating screen 200.

[0052] In this embodiment, a vibrating screen 200 is set between the magnetic separator 100 and the vibrating fluidized bed. The vibrating screen 200 can screen out large impurities in the product. The screened product material has better flowability and is more uniform. After entering the magnetic separator 100, it can make more full contact with the magnetic rods 122 inside, further improving the effect of the magnetic separator 100 in removing magnetic impurities from the product.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
