Description

A raw material drug screening machine with magnetic adsorption Technical Field

[0001] This utility model relates to the field of raw material screening technology, and in particular to a raw material screening machine with magnetic adsorption. Background Technology

[0002] Active pharmaceutical ingredients (APIs) are the core components of drugs that have pharmacological activity. They can directly act on the physiological functions of the human or animal body through diagnosis, treatment, relief or prevention of diseases. APIs are the basic substances of drug formulations and need to be processed by adding excipients and other steps to make dosage forms suitable for patients. During the processing of APIs, sieving can remove impurities and improve the quality of APIs.

[0003] A search revealed Chinese patent application number 202321233234.1, which discloses a rapid screening and filtration device for active pharmaceutical ingredients (APIs). The device includes: a support assembly comprising an outer ring and a vibration assembly disposed around the outer ring; and a filtration assembly comprising a feeding assembly, an external connector, and filtration units. The vibration assembly is connected to the feeding assembly via the external connector, and the filtration units are connected to the end of the feeding assembly. Each filtration unit comprises a first filtration unit, a second filtration unit, and a third filtration unit, which are nested sequentially. The vibration assembly drives the feeding assembly and filtration units to vibrate synchronously. This invention uses a vibration assembly to drive the filtration units to vibrate synchronously, preventing insoluble substances from adhering to and clogging the filtration units, thus improving the filtration efficiency of the APIs. The nested assembly of the filtration units facilitates disassembly and cleaning, further enhancing the overall filtration and screening efficiency.

[0004] While the aforementioned patent can improve the filtration efficiency of raw materials through vibration, it is inconvenient to clean impurities such as iron filings from the raw materials during filtration. Furthermore, the conveying and screening process of the raw materials is conducted in an open environment, which can cause dust from the raw materials to spill out, increasing the concentration of dust in the air, endangering the health of workers, and posing safety hazards.

[0005] Therefore, there is an urgent need for a raw material screening machine with magnetic adsorption to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to solve the problems in the prior art where it is inconvenient to clean iron filings and other debris from raw pharmaceutical materials during screening, and where dust overflow can easily lead to health hazards and safety risks. Therefore, this invention proposes a raw pharmaceutical material screening machine with magnetic adsorption.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A raw material screening machine with magnetic adsorption includes a vibrating screen and a discharge tank installed at the top inlet of the vibrating screen. A uniform feeder is provided at the bottom outlet of the discharge tank. The bottom of the uniform feeder is connected to the top inlet of the vibrating screen via a flexible connecting pipe. A receiving hopper is provided below the outlet of the vibrating screen. An iron separator is installed at the top inlet of the receiving hopper. The top inlet of the iron separator is connected to the outlet of the vibrating screen via a flexible connecting pipe. A stirring mechanism is provided at the top of the discharge tank. The stirring mechanism includes a mounting plate fixedly connected to the top of the discharge tank. A second motor is fixedly connected to the top of the mounting plate. The output end of the second motor passes through the mounting plate and is connected to a rotating shaft. Multiple stirring frames are installed in a ring shape on the outer side of the rotating shaft.

[0009] As a preferred technical solution of this application, the bottom of the vibrating screen is equipped with a base, and the top four corners of the base are connected to supports by multiple uprights.

[0010] As a preferred technical solution of this application, the iron separator includes a housing, a baffle is slidably installed on one side of the housing, and sliding rods are installed at both ends of the baffle. The sliding rods are slidably connected to the sleeve on the iron separator. A first motor is fixedly installed on the outside of the baffle. The output end of the first motor passes through the baffle and is connected to a rotating plate. Multiple magnetic rods are installed in a ring on the rotating plate.

[0011] As a preferred technical solution of this application, a cleaning mechanism is installed on the outer side of the rotating plate. The cleaning mechanism includes a scraper and a plurality of sleeves detachably connected to the scraper. The number of sleeves is the same as the number of magnetic rods. The sleeves are fitted onto the magnetic rods, and cotton sleeves are installed inside the sleeves.

[0012] As a preferred technical solution of this application, a rotating seat is rotatably mounted at the center of the magnetic rod, a handle is fixedly mounted at one end of the rotating seat, a stud is fixedly mounted at the other end of the rotating seat, and a screw hole that mates with the stud is opened at the center of the rotating plate.

[0013] As a preferred technical solution of this application, a fixing plate is fixedly installed on one end of the sleeve, and the fixing plate is connected to the scraper plate by screws.

[0014] As a preferred technical solution of this application, the inner side of the stirring rack is provided with a stirring net.

[0015] Compared with the prior art, this utility model provides a raw material screening machine with magnetic adsorption, which has the following beneficial effects:

[0016] 1. This raw material screening machine with magnetic adsorption is designed so that the feed inlet of the vibrating screen is connected to the uniform feeder and the discharge outlet of the vibrating screen is connected to the iron remover through flexible connecting pipes. This effectively seals the feed and discharge positions of the vibrating screen, preventing raw material dust from overflowing during screening and reducing the dust concentration in the air. This solves the problem in the existing technology that the screening of raw material dust can easily lead to dust overflow, which can cause harm to health and safety hazards.

[0017] 2. This raw material screening machine with magnetic adsorption, through a cleaning mechanism sleeved on the magnetic rod, can quickly clean the surface of the magnetic rod by multiple cotton sleeves installed on the scraper after a period of use of the iron remover, removing the iron filings and other impurities adsorbed on it. This effectively improves the cleaning efficiency and solves the problem in the existing technology where workers need to hold cotton cloths to clean the magnetic rods one by one, resulting in low cleaning efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Embodiments

[0026] Referring to Figures 1-5, a raw material screening machine with magnetic adsorption includes a vibrating screen 4 and a feeding tank 6 installed at the top inlet of the vibrating screen 4. A uniform feeder 8 is provided at the bottom outlet of the feeding tank 6. The bottom of the uniform feeder 8 is connected to the top inlet of the vibrating screen 4 through a flexible connecting pipe 3. The uniform feeder 8 can make the feeding more uniform and convenient. A receiving bucket 1 is provided below the outlet of the vibrating screen 4. A magnetic separator 2 is installed at the top inlet of the receiving bucket 1. The top inlet of the magnetic separator 2 is connected to the outlet of the vibrating screen 4 through a flexible connecting pipe 3. After the raw material is screened by the vibrating screen 4, it is collected in the receiving bucket 1 after iron removal by the magnetic separator 2, which can effectively remove iron filings and other metals from the raw material.

[0027] The discharge port of the iron remover 2 and the discharge port of the vibrating screen 4, as well as the feed port at the top of the vibrating screen 4 and the uniform feeder 8, are all connected by a flexible connecting pipe 3. When the vibrating screen 4 is screening, it can effectively reduce dust pollution and improve the safety of screening. The feeding into the discharge tank 6 and the discharge from the receiving bucket 1 are all carried out by a vacuum feeder. Through the closed conveying space, the dust pollution during the screening of raw materials is reduced.

[0028] The bottom of the vibrating screen 4 is equipped with a base 9. The top four corners of the base 9 are connected to brackets 5 by multiple uprights. The brackets 5 support the discharge tank 6, which keeps the discharge tank 6 above the vibrating screen 4 during use, making it more convenient to introduce materials into the vibrating screen 4.

[0029] Referring to Figures 2, 3, and 4, the iron separator 2 further includes a housing 201 with openings at the top and bottom, which are connected to the discharge port of the vibrating screen 4 and the inlet of the receiving hopper 1, respectively, for filtering iron filings and other metals from the screened raw materials. A baffle 204 is slidably installed on one side of the housing 201, and sliding rods 203 are installed at both ends of the baffle 204. The sliding rods 203 are slidably connected to the sleeve on the iron separator 2. When the baffle 204 is pulled out, it is supported by the sliding rods 203. A first motor 205 is fixedly installed on the outside of the baffle 204. The output end of the first motor 205 passes through the baffle 204 and is connected to a rotating plate 206. Multiple magnetic rods 202 are installed in a ring on the rotating plate 206. During use, the first motor 205 drives the magnetic rods 202 to rotate and remove iron from the screened raw materials. At the same time, the multiple magnetic rods 202 can also be used to disperse the material and reduce the agglomeration of the material.

[0030] A cleaning mechanism is installed on the outside of the rotating plate 206. The cleaning mechanism includes a scraper 207 and multiple sleeves 208 detachably connected to the scraper 207. The number of sleeves 208 is the same as the number of magnetic rods 202. The sleeves 208 are fitted onto the magnetic rods 202. A cotton sleeve 209 is installed inside the sleeve 208. After the iron remover 2 has been used for a period of time, the magnetic rods 202 are pulled out, and then the scraper 207 is pulled. The cotton sleeve 209 is used to clean the iron filings and other metals adsorbed on the magnetic rods 202. The operation is simple and quick. There is no need to wipe the magnetic rods 202 separately, which helps to improve the cleaning efficiency of the magnetic rods 202.

[0031] A rotating base 210 is rotatably mounted at the center of the magnetic rod 202. A handle 211 is fixedly mounted at one end of the rotating base 210, making it more convenient to pull the scraper 207. A stud 212 is fixedly mounted at the other end of the rotating base 210. A screw hole that mates with the stud 212 is opened at the center of the rotating plate 206. The scraper 207 can be connected and fixed to the rotating plate 206 through the stud 212, so as to keep the scraper 207 stable during iron removal.

[0032] A fixing plate 213 is fixedly installed on one end of the sleeve 208. The fixing plate 213 is connected to the scraper 207 by screws, which facilitates the cleaning and replacement of the sleeve 208 and the cotton sleeve 209 inside the sleeve 208 after disassembly, thereby improving the cleaning effect on the magnetic rod 202.

[0033] Referring to Figure 5, furthermore, the top of the discharge tank 6 is provided with a stirring mechanism 7, and a feed pipe is provided on one side of the stirring mechanism 7. The stirring mechanism 7 stirs the raw materials inside the discharge tank 6 to reduce agglomeration and make the feeding more uniform. The stirring mechanism 7 includes a mounting plate 702 fixedly connected to the top of the discharge tank 6. A second motor 701 is fixedly connected to the top of the mounting plate 702. The output end of the second motor 701 passes through the mounting plate 702 and is connected to a rotating shaft 703. Multiple stirring frames 704 are installed in a ring on the outer side of the rotating shaft 703, and a stirring net 705 is provided on the inner side of the stirring frame 704. When rotating, the raw materials inside the discharge tank 6 are quickly stirred and crushed by the stirring frame 704 and the stirring net 705.

[0034] Specifically, when this raw material screening machine with magnetic adsorption is working: the raw material inside the discharge tank 6 is conveyed into the vibrating screen 4 by the uniform feeder 8. After being screened by the discharge tank 6, it enters the iron remover 2. The iron remover 2 then adsorbs the iron filings and other metals in the raw material and collects them into the receiving bucket 1. Finally, the material in the receiving bucket 1 is extracted by the vacuum feeder.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
