Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical raw material processing technology, specifically to a pharmaceutical raw material sieving device. Background Technology

[0002] Pharmaceutical raw materials are the original materials used in drug production and are the basic components of drug formulations. Their quality directly affects the safety, efficacy, and stability of drugs. Before being put into use, pharmaceutical raw materials need to undergo multiple processing steps. Among them, sieving is an important step. It is necessary to separate raw materials of different particle sizes through sieving equipment to meet the precision requirements of subsequent production. At the same time, sieving can remove impurities and foreign objects from the raw materials, improve the purity of the raw materials, avoid impurities affecting the safety and efficacy of drugs, and reduce the risk of damage to subsequent production equipment caused by impurities.

[0003] Traditionally, during the screening process, large particles of raw materials are difficult to remove from the equipment and are inconvenient to clean. The removal and maintenance of the filter plates used for screening are cumbersome and can easily delay the use of the equipment. In addition, it is difficult to control the feeding speed during the pouring process. Feeding too fast or too much can affect the screening efficiency. Raw materials can easily clog the bottom of the feeding hopper and hinder the operation of the equipment.

[0004] Therefore, it is necessary to provide a new drug raw material screening device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a pharmaceutical raw material sieving device that facilitates feeding, cleaning of raw materials and maintenance of filter plates, and efficient screening and collection of raw materials.

[0006] To solve the above-mentioned technical problems, the pharmaceutical raw material sieving equipment provided by this utility model includes: an operating box, a feeding hopper fixedly installed on the top of the operating box, an electric motor fixedly installed on the top of the operating box, a circular rod rotatably installed on the feeding hopper, one end of the circular rod being fixedly connected to the output shaft of the electric motor, multiple feeding blades welded on the circular rod, three connecting rods slidably installed on one side of the operating box, three connecting rods slidably installed on the other side of the operating box, three placement boxes fixedly installed between the three connecting rods 1 and the three connecting rods 2, filter plates slidably installed in each of the three placement boxes, a common connecting plate fixedly installed on one end of the three connecting rods 1, and a fixed plate on one side of the operating box. The control box is equipped with a fixed frame, on which an electric motor is mounted. A housing is fixedly installed at one end of the corresponding connecting rod. Racks are fixedly installed on the top and bottom inner walls of the housing. An adapter rod is fixedly installed on the output shaft of the electric motor, and a half gear is fixedly sleeved on the adapter rod. The half gear meshes with the corresponding rack. A material retrieval port is opened on one side of the control box. A U-shaped rod is fixedly installed on one side of the control box. A spiral block is slidably installed on the U-shaped rod. A baffle plate is fixedly installed on one side of the spiral block. A positioning block is fixedly installed on one side of the control box, and the baffle plate is slidably installed on the positioning block. A discharge port is opened at the bottom of the control box, and a guide plate is fixedly installed at the bottom of the control box.

[0007] Preferably, four reinforcing rods are fixedly installed at the bottom of the feeding hopper, and the bottom ends of the four reinforcing rods are fixedly connected to the top of the control box.

[0008] Preferably, each side of the operation box has three strip-shaped holes, and the top and bottom of the three connecting rods one and the three connecting rods two are each inlaid with three rolling balls. The multiple rolling balls are respectively in contact with the top and bottom inner walls of the six strip-shaped holes, and the ends of the two corresponding connecting rods two away from the two placement boxes are fixedly installed with limit blocks.

[0009] Preferably, a support base is fixedly installed on the top inner wall of the fixing frame, and the support base is fixedly connected to the base of the second electric motor.

[0012] Compared with related technologies, the drug raw material sieving equipment provided by this utility model has the following beneficial effects: This invention allows for the simultaneous pouring of a fixed quantity of raw material into the hopper. Driven by an electric motor, multiple feeding blades rotate, controlling the material's position at the bottom for efficient and precise screening. This prevents blockage at the bottom of the hopper and reduces the need for frequent feeding, increasing equipment flexibility. A second electric motor drives the housing to slide back and forth, causing three placement boxes and three filter plates to slide repeatedly within the control box for screening. This facilitates step-by-step screening as the raw material falls, ensuring finer and more precise screening. A simple push-and-rotate operation disconnects the baffle plate from the control box, quickly opening the retrieval port to remove the three filter plates from the placement boxes. Large particles collected in the filter plates are then quickly dumped out, and the plates are cleaned and unblocked for maintenance and material removal. The operation is convenient and fast, reducing downtime and improving work efficiency. Attached Figure Description

Racks 14 are fixedly installed on the inner walls of the top and bottom of the housing 13. The two racks 14 are staggered. An adapter rod 15 is fixedly installed on the output shaft of the electric motor 12. A half gear 16 is fixedly sleeved on the adapter rod 15. The half gear 16 meshes with the rack 14 located below. A retrieval port 17 is opened on one side of the operating box 1, through which the three filters can be easily removed. Plate 9 is taken out from operation box 1. A U-shaped rod 18 is fixedly installed on one side of operation box 1. A spiral block 19 is slidably installed on the U-shaped rod 18. A baffle plate 20 is fixedly installed on one side of the spiral block 19. A handle is fixedly installed on one side of the baffle plate 20. The baffle plate 20 is adapted to the material receiving port 17. A positioning block 21 is fixedly installed on one side of operation box 1. The positioning block 21 is U-shaped.

A guide plate 23 is fixedly installed at the bottom of operation box 1. The guide plate 23 can guide the fine material that has been screened, making it convenient to collect the fine material.

[0017] In order to reinforce the feeding hopper 2, increase its stability, and reduce its load, four reinforcing rods are fixedly installed at the bottom of the feeding hopper 2, and the bottom ends of the four reinforcing rods are fixedly connected to the top of the control box 1.

[0018] In order to allow sliding space for the three connecting rods 6 and 7 and limit the movement range of the placement box 8, in this method, three strip holes are opened on both sides of the operation box 1, and three rolling balls are embedded in the top and bottom of the three connecting rods 6 and 7 respectively. The multiple rolling balls are in contact with the top and bottom inner walls of the six strip holes respectively, and limit blocks are fixedly installed on the ends of the two connecting rods 7 away from the two placement boxes 8.

[0019] To ensure the stability of the installation of the electric motor 12 and the adapter rod 15, a support base is fixedly installed on the top inner wall of the fixing frame 11. The support base is fixedly connected to the base of the electric motor 12. The same vertical plate is fixedly installed between the top inner wall and the bottom inner wall of the fixing frame 11.

[0020] To ensure the sealing of the control box 1, in this method, a sealing gasket is fixedly installed on one side of the baffle plate 20, and one side of the sealing gasket is in contact with the control box 1.

[0021] The working principle of the drug raw material sieving equipment provided by this utility model is as follows: When raw materials need to be screened, electric motor 3 and electric motor 12 are started. The output shaft of electric motor 3 drives the circular rod 4 and multiple feeding blades 5 to rotate. Electric motor 12 drives the half gear 16 to rotate through the adapter rod 15. The half gear 16 drives the box body 13 to move in the direction of the baffle plate 20 through a rack 14. When the teeth on the half gear 16 rotate to mesh with another rack 14, it drives the box body 13 to move in the opposite direction of the baffle plate 20. Under the continuous drive of electric motor 12, the box body 13 slides back and forth on one side of the operating box 1. Through the cooperation of three connecting rods 6 and three connecting rods 7, the three placement boxes 8 and three filter plates 9 are driven to swing back and forth in the operating box 1 to achieve the screening action.

[0022] The raw material to be screened is poured into the feeding hopper 2. Guided by multiple feeding blades 5, the raw material slowly falls into the operating box 1 and passes through three filter plates 9 from top to bottom, performing triple screening. The screened raw material falls onto the bottom inner wall of the operating box 1 and slides out of the operating box 1 along the feed plate 23 for easy collection. Larger particles will be intercepted in the three filter plates 9. After the screening is completed, push the baffle plate 20 upward. The baffle plate 20 drives the U-shaped block 19 to slide upward on the U-shaped rod 18. The baffle plate 20 will slide out from the positioning block 21. Then rotate the baffle plate 20 clockwise. The extraction port 17, which is no longer blocked by the baffle plate 20, will be exposed. Through the extraction port 17, the three filter plates 9 can be removed from the three placement boxes 8, and the large particles collected in the three filter plates 9 can be poured out. The three filter plates 9 can also be cleaned to ensure their unobstructed flow.

[0023] Compared with related technologies, the drug raw material sieving equipment provided by this utility model has the following beneficial effects: In this invention, a fixed amount of raw material is poured into the feeding hopper 2 at once. Driven by an electric motor 3, multiple feeding blades 5 rotate, which controls the bottom of the raw material, facilitates quantitative screening, ensures screening efficiency, prevents clogging at the bottom of the feeding hopper 2, and avoids frequent feeding, improving the flexibility of equipment use. Driven by an electric motor 12, the housing 13 slides back and forth, causing the three placement boxes 8 and three filter plates 9 to slide back and forth in the operating box 1 to perform screening. This facilitates step-by-step screening as the raw material falls, ensuring fine screening and improving screening accuracy. A two-step operation of pushing and then rotating disconnects the baffle plate 20 from the operating box 1, thereby quickly opening the extraction port 17 to remove the three filter plates 9 from the three placement boxes 8. Large particles of raw material collected in the three filter plates 9 after screening are quickly poured out, and the filter plates 9 are unblocked and cleaned, facilitating maintenance and raw material cleaning. The operation is convenient and fast, reducing equipment downtime and improving work efficiency.
