Description

Technical Field

[0001] This utility model belongs to the field of biopharmaceutical processing equipment technology, and in particular to a structure for cleaning drug raw materials for biopharmaceuticals. Background Technology

[0002] In the biopharmaceutical field, ensuring the cleanliness of drug raw materials is crucial for guaranteeing drug quality and safety. This is especially true for natural medicinal materials such as freshly harvested herbs, whose surfaces may be covered with dirt and other impurities. These can affect the safety and efficacy of the final drug. Washing effectively removes these surface impurities, ensuring the purity of the drug raw materials.

[0003] Traditional pharmaceutical raw material cleaning equipment typically consists of a simple cleaning tank and conveying device, using water flow to remove surface impurities and contaminants. However, these traditional devices have limitations. For example, they rely primarily on water flow directly from nozzles to rinse the surface of the pharmaceutical raw materials. This single rinsing method is insufficient to thoroughly remove impurities and dirt adhering to complex-shaped pharmaceutical raw materials (herbs) or from the fine crevices within them. Without additional mechanical cleaning force, residual dust and impurities easily remain on the raw materials. If cleaning is incomplete, these residual impurities directly affect the purity of the pharmaceutical raw materials, thus impacting the quality of the final product. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning structure for pharmaceutical raw materials used in biopharmaceuticals, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pharmaceutical raw material cleaning structure, comprising a pharmaceutical raw material cleaning tank, a stainless steel conveyor belt disposed within the tank cavity, multiple cleaning nozzles disposed above the stainless steel conveyor belt and located on the top surface of the pharmaceutical raw material cleaning tank, and multiple nozzles equidistantly disposed on the bottom surface of each cleaning nozzle. One end of the pharmaceutical raw material cleaning tank is provided with an input port for inputting pharmaceutical raw materials, and the end of the pharmaceutical raw material cleaning tank away from the input port is provided with a discharge drain box. The interior of the discharge drain box has a drain for carrying the cleaned and discharged pharmaceutical raw materials. The material chamber has an inclined slope structure at the bottom of its inner wall near the stainless steel conveyor belt. A rotating shaft is rotatably installed between the two inner walls of the material chamber. A drive plate is symmetrically welded around the rotating shaft. A servo motor is installed on the outer wall of the material draining box. The output shaft of the servo motor is connected to one end of the rotating shaft. An arc-shaped draining filter screen for draining pharmaceutical raw materials is rotatably installed in the inner cavity of the material chamber away from the rotating shaft. The two ends of the rotating shaft are connected to the bottom end of the arc-shaped draining filter screen through a traction assembly, which drives the arc-shaped draining filter screen to perform reciprocating and lifting and lowering actions to generate a vibrating force.

[0006] In a preferred embodiment, the inner wall of the end of the feeding chamber away from the stainless steel conveyor belt is embedded with a draining and sewage discharge net, which is covered by an arc-shaped draining filter screen deep at the bottom of the feeding chamber.

[0007] In this preferred embodiment, both ends of the rotating shaft are connected to the inner walls of the two sides of the discharge drain box via sealed bearings, and rubber strips are glued to the opposite ends of the two drive plates.

[0008] In a preferred embodiment, the pulling assembly includes striking push rods symmetrically welded to the periphery of both ends of the rotating shaft, T-shaped turntables rotatably mounted on the inner walls of both sides of the feeding chamber, limiting rods welded to the top of each T-shaped turntable, limiting blocks welded to the inner walls of both sides of the feeding chamber, receiving end push plates welded to one side of the bottom of each T-shaped turntable, and pull ropes symmetrically connected to the bottom of the arc-shaped drain filter screen.

[0009] In this preferred embodiment, the two striking push rods are respectively located between the drive plate and the adjacent sealed bearing, the top of the striking push rods dynamically abuts against the receiving end push plate, and each T-shaped turntable is located above the adjacent sealed bearing.

[0010] In this preferred embodiment, the limiting block is located above the adjacent T-shaped turntable and prevents the limiting rod from rotating clockwise. Each T-shaped turntable has a rope groove on its circumference at one end near the inner wall of the feeding chamber.

[0011] In this preferred embodiment, the ends of the two pull ropes away from the arc-shaped drain filter cover are the winding ends. Each winding end is wrapped around the bottom of the T-shaped turntable in the rope groove, and the end of the winding end away from the pull rope is fixedly connected to the inner wall of the rope groove near the limiting rod.

[0012] In this preferred embodiment, the top two ends of the arc-shaped drain filter screen away from the pull rope are fixedly connected with pins. The two pins are respectively rotatably installed in the inner walls of the two sides of the discharge chamber so that the arc-shaped drain filter screen can be flipped around the pins.

[0013] In a preferred embodiment, a transparent protective cover is rotatably installed above the inner cavity of the discharge chamber and on the top inner wall of the discharge drain box, and a handle is installed on the top surface of one end of the transparent protective cover.

[0014] In a preferred embodiment, a sewage chamber is located directly below the stainless steel conveyor belt and at the bottom of the drug raw material washing tank. A sewage pipe is connected through the outer wall of the drug raw material washing tank, and one end of the sewage pipe extends into the sewage chamber.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This biopharmaceutical raw material cleaning structure features a servo motor-driven shaft and drive plate. The servo motor drives the shaft to rotate clockwise, which in turn drives the drive plate welded to it to push the raw materials piled on the slope down. This prevents the raw materials from accumulating on the slope and blocking the downward path, ensuring smooth material movement and avoiding cleaning interruptions or reduced efficiency caused by blockages.

[0017] When the pharmaceutical raw materials are pushed onto the arc-shaped drain filter, the pulling component causes the filter to reciprocate in a lifting and lowering motion, creating a vibrating force. This not only helps remove residual moisture but also shakes off dust and other impurities, ensuring the cleanliness of the pharmaceutical raw materials. This step is more effective than traditional static draining, improving cleaning quality. Excess water flows from the arc-shaped drain filter into the drain drain screen at the bottom of the feeding chamber and is discharged through it to an externally connected wastewater tank, ensuring effective discharge of wastewater during the cleaning process, avoiding secondary pollution, and maintaining a clean working environment.

[0018] This technical solution achieves an automated and efficient cleaning process through servo motor drive, inclined slope design, and vibrating screen function, significantly improving cleaning efficiency. Compared with traditional equipment, this solution not only removes residual moisture and impurities through water rinsing but also combines vibrating screen force to ensure the high cleanliness of pharmaceutical raw materials.

Detailed Implementation

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0030] This embodiment provides, for example Figures 1 to 6The diagram illustrates a pharmaceutical raw material cleaning structure, comprising a raw material cleaning tank 1, a tank cavity 2, a stainless steel conveyor belt 3 disposed within the tank cavity 2, multiple cleaning nozzles 4 positioned above the stainless steel conveyor belt 3 and located on the top surface of the raw material cleaning tank 1, and multiple nozzles 5 equidistantly disposed on the bottom surface of each cleaning nozzle 4. One end of the raw material cleaning tank 1 has an input port 6 for inputting pharmaceutical raw materials (such as herbs), and the other end of the raw material cleaning tank 1 away from the input port 6 has a discharge drain box 7. The discharge drain box 7 has a discharge chamber 9 for receiving the cleaned and discharged pharmaceutical raw materials. The inner bottom wall of the discharge chamber 9, near the stainless steel conveyor belt 3, has an inclined slope structure, allowing the pharmaceutical raw materials to slide down from the stainless steel conveyor belt 3 into the discharge chamber 9 at the end away from the stainless steel conveyor belt 3. A rotating shaft 15 is rotatably mounted between the two inner walls of the discharge chamber 9, and drive plates 16 are symmetrically welded around the rotating shaft 15. A servo motor 13 is installed on the outer wall of the drainage tank 7. The output shaft of the servo motor 13 is connected to one end of the rotating shaft 15, so that when the servo motor 13 drives the rotating shaft 15 to rotate the drive plate 16 clockwise, the drive plate 16 will push the accumulated drug raw materials on the slope to the depth of the discharge chamber 9, preventing the path of the drug raw materials from being blocked. An arc-shaped drainage filter screen 12 for draining the drug raw materials is rotatably installed in the inner cavity of the discharge chamber 9 at the end away from the rotating shaft 15. When the raw material is propelled and thrown deep into the inner cavity of the feeding chamber 9 onto the arc-shaped draining filter screen 12, the force of the thrust causes the raw material to impact the arc-shaped draining filter screen 12, thereby draining excess water from the raw material. The raw material itself remains on the arc-shaped draining filter screen 12, while the water droplets flow out. The two ends of the rotating shaft 15 are connected to the bottom end of the arc-shaped draining filter screen 12 through the pulling assembly, which drives the arc-shaped draining filter screen 12 to perform reciprocating and lifting and lowering actions to generate a vibrating screening force. When the rotating shaft 15 rotates clockwise, the pulling and contracting of the pulling assembly drives the bottom end of the arc-shaped draining filter screen 12 to tilt up and down. When the arc-shaped draining filter screen 12 is pulled up and down in this reciprocating motion, it vibrates and screens the raw material on it, not only removing dust and impurities but also further draining water.

[0031] In this embodiment, a draining and sewage discharge net 14 is embedded in the inner wall of the end of the feeding chamber 9 away from the stainless steel conveyor belt 3. The draining and sewage discharge net 14 is covered by an arc-shaped draining filter cover 12 deep at the bottom of the feeding chamber 9. The inclined slope inside the feeding chamber 9 has its highest point near the stainless steel conveyor belt 3 and its lowest point near the draining and sewage discharge net 14, which helps the drug raw materials slide down to the depth of the feeding chamber 9. After excess water is drained, it is discharged from the draining and sewage discharge net 14 into an externally connected sewage tank (not shown in the figure).

[0032] In this embodiment, both ends of the rotating shaft 15 are connected to the inner walls of the two sides of the discharge drain box 7 through sealed bearings 18. The sealed bearings 18 are fixedly embedded in the inner wall of the discharge drain box 7. Rubber strips 17 are glued to the opposite ends of the two drive plates 16. The design of the rubber strips 17 helps to reduce damage when pushing the drug raw materials and protect the drug raw materials from physical damage.

[0033] In this embodiment, the pulling assembly includes striking push rods 19 symmetrically welded to the periphery of both ends of the rotating shaft 15, T-shaped turntables 20 rotatably mounted on the inner walls of both sides of the feeding chamber 9, limiting rods 23 welded to the top of each T-shaped turntable 20, limiting blocks 22 welded to the inner walls of both sides of the feeding chamber 9, receiving end push plates 21 welded to one side of the bottom end of each T-shaped turntable 20, and pull ropes 26 symmetrically connected to the bottom end of the arc-shaped drain filter screen 12.

[0034] In this embodiment, two striking push rods 19 are located between the drive plate 16 and the adjacent sealed bearing 18, respectively. The top of the striking push rod 19 dynamically abuts against the receiving end push plate 21. Each T-shaped turntable 20 is located above the adjacent sealed bearing 18. The T-shaped turntable 20 has a horizontal structure, and the tail end shaft of the T-shaped turntable 20 is connected to the inner wall of the feeding chamber 9 through a bearing, thereby enabling the T-shaped turntable 20 to rotate on the inner wall of the feeding chamber 9.

[0035] In this embodiment, the limiting block 22 is located above the adjacent T-shaped turntable 20 and blocks the limiting rod 23 from rotating clockwise, so that the limiting rod 23 hits the limiting block 22. Each T-shaped turntable 20 has a rope groove 24 on one side near the inner wall of the feeding chamber 9.

[0036] In this embodiment, the ends of the two pull ropes 26 away from the arc-shaped drain filter screen 12 are the winding ends 27. Each winding end 27 is wrapped around the bottom of the T-shaped turntable 20 in the rope groove 24, and the end of the winding end 27 away from the pull rope 26 is fixedly connected to the inner wall of the end of the rope groove 24 near the limiting rod 23. When the rotating shaft 15 rotates clockwise, it drives the striking push rod 19 to strike the receiving end push plate 21, causing the striking push rod 19 to push the receiving end push plate 21. The receiving end push plate 21 then drives the T-shaped turntable 20 to rotate counterclockwise on the inner wall of the feeding chamber 9. Meanwhile, the limiting rod 23 moves away from the limiting stop block 22. Through the counterclockwise rotation design of the T-shaped turntable 20, the pulling rope 26 continues to wind in the rope groove 24, thereby causing the pulling rope 26 to pull the bottom end of the arc-shaped drain filter screen 12 to rise. When the striking push rod 19 strikes the receiving end push plate 21, it will quickly detach from the receiving end push plate 21 and continue to rotate. Under the gravity of the arc-shaped drain filter screen 12, the bottom end of the arc-shaped drain filter screen 12 is pulled... As rope 26 retracts, the bottom of the arc-shaped drain filter cover 12 falls. When rope 26 and winding end 27 retract, they pull the T-shaped turntable 20 to rotate clockwise on the inner wall of the feeding chamber 9, causing the arc-shaped drain filter cover 12 to fall and hit the slope of the feeding chamber 9. This causes the arc-shaped drain filter cover 12 to generate a vibrating force. Meanwhile, the limiting rod 23 hits the limiting block 22 to limit the T-shaped turntable 20, so that the receiving end push plate 21 is always located in front of the clockwise direction of the striking push rod 19. This helps the receiving end push plate 21 to receive the impact force, thus forming a cycle of vibrating force and one rotation of the rotating shaft 15. This cycle continues, causing the arc-shaped drain filter cover 12 to perform a vibrating force that repeatedly lifts and falls.

[0037] In this embodiment, the top two ends of the arc-shaped drain filter cover 12 away from the pull rope 26 are fixedly connected with pins 25. The two pins 25 are respectively rotatably installed in the inner walls of the two sides of the discharge chamber 9 so that the arc-shaped drain filter cover 12 can be flipped around the pins 25.

[0038] In this embodiment, a transparent protective cover 10 is rotatably installed above the inner cavity of the feeding chamber 9 and on the top inner wall of the feeding drain box 7. A handle 11 is installed on the top surface of one end of the transparent protective cover 10. The design of the transparent protective cover 10 helps to prevent water from splashing out of the feeding chamber 9. At the same time, the material design of the transparent acrylic plate helps to see the inside of the feeding chamber 9. In addition, the handle 11 can be used to flip open the transparent protective cover 10 to collect and remove the drug raw materials in the feeding chamber 9.

[0039] In this embodiment, a sewage chamber is located directly below the stainless steel conveyor belt 3 and at the bottom of the drug raw material washing tank 1. A sewage pipe 8 is connected through the outer wall of the drug raw material washing tank 1, with one end of the sewage pipe 8 extending into the sewage chamber. A valve is located inside the discharge end of the sewage pipe 8 for discharging sewage. The nozzle 5 is connected to an external water pipe and water pump (not shown in the figure) for water input. An electrical control box is located on the outer wall of the drug raw material washing tank 1, containing a PLC for controlling the opening and closing of the servo motor 13.

[0040] Working principle:

[0041] This biopharmaceutical raw material cleaning structure allows raw materials to be cleaned, such as harvested Chinese herbs, to be fed into the equipment through an input port 6 located at one end of the raw material cleaning tank 1. The raw materials are placed on a stainless steel conveyor belt 3 located inside the tank cavity 2. Multiple cleaning spray pipes 4 are positioned above the stainless steel conveyor belt 3, and each cleaning spray pipe 4 has multiple nozzles 5 evenly spaced at its bottom. These nozzles 5 are supplied with water through externally connected water pipes and a water pump, spraying and cleaning the passing raw materials, using the force of the water flow to remove impurities and contaminants from the surface of the raw materials.

[0042] After cleaning, the raw materials are moved by the stainless steel conveyor belt 3 to the end of the raw material cleaning tank 1 away from the input port 6, that is, the location of the discharge drain box 7. During this process, some water will be naturally drained out through the stainless steel conveyor belt 3, reducing the amount of water for subsequent treatment.

[0043] Upon reaching the discharge draining box 7, the drug raw materials slide into the discharge chamber 9, which has an inclined slope structure. The servo motor 13 drives the rotating shaft 15 and its drive plate 16 to rotate clockwise, helping the accumulated drug raw materials slide down the slope onto the arc-shaped draining filter screen 12, preventing the drug raw materials from accumulating on the slope and blocking the sliding path, while further draining the water. When the drug raw materials are pushed onto the arc-shaped draining filter screen 12, the pulling components, including the impact push rod 19, T-shaped turntable 20, limit rod 23, limit stop 22, receiving end push plate 21, and pull rope 26, act as a pull mechanism. This causes the arc-shaped drain filter cover 12 to reciprocate by lifting and lowering, creating a vibrating force that not only helps remove residual water but also shakes off dust and other impurities, ensuring the cleanliness of the raw materials. Excess water flows from the arc-shaped drain filter cover 12 into the drain and sewage discharge net 14 at the bottom of the feeding chamber 9 and is discharged through it into the externally connected sewage tank. The transparent protective cover 10 can be flipped open, and the cleaned and drained raw materials can be easily removed through the handle 11, ensuring that the wastewater during the cleaning process is effectively discharged and facilitating the collection of the cleaned raw materials.
