Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, specifically to a medicinal material cleaning device for preparing pharmaceutical preparations. Background Technology

[0002] In the preparation of medicines, the cleaning of medicinal materials is a crucial preliminary treatment step. During the collection and transportation of medicinal materials, a large amount of soil, impurities, microorganisms, etc., will adhere to their surface. If these impurities are not thoroughly removed, they will not only affect the quality and purity of the medicine, but may also adversely affect subsequent pharmaceutical processes, and even affect the efficacy and safety of the medicine.

[0003] Existing cleaning devices often fail to perform cleaning during the transport of medicinal herbs. For example, herbs must be placed in a mixing tank, cleaned, and then removed, increasing cleaning time and reducing production efficiency. Other devices use spraying during transport, which improves efficiency, but uneven water distribution can lead to incomplete cleaning of some herbs. Furthermore, spraying wastes significant amounts of water, increasing production costs. Therefore, a new medicinal herb cleaning device is needed that ensures thorough cleaning during transport while conserving water resources. Utility Model Content

[0004] In view of the above, and to solve the problems existing in the prior art, this utility model provides a medicinal material cleaning device for preparing pharmaceuticals.

[0005] The technical solution is a medicinal material cleaning device for preparing pharmaceuticals, including a tank containing liquid inside. Pipes with different inner diameters are rotatably connected inside the tank. The lower part of the pipes has a through hole for liquid to pass through. One end of the pipe extending out of the tank is provided as an inlet, and the other end of the pipe extending out of the tank is provided as an outlet. This forms a structure in which the material moves from the inlet to the outlet by rotating the pipes, and the liquid inside the tank cleans the material between the inlet and the outlet.

[0006] Preferably, a helical blade is installed inside the pipe.

[0007] Preferably, the pipeline includes an intermediate pipe, one end of which is fixedly connected to a first pipe and the other end of which is fixedly connected to a second pipe. The intermediate pipe has a columnar structure, while the first and second pipes have a platform-like structure. The portion of the small end of the first pipe extending outward forms a feed inlet, and the portion of the small end of the second pipe extending outward forms a discharge outlet. The spiral blades are located inside the intermediate pipe and the second pipe.

[0008] Preferably, the first pipe, the second pipe, and the intermediate pipe are coaxial, the axis of the pipes is arranged parallel to the horizontal plane, and the lower part of the intermediate pipe is located in the liquid inside the tank.

[0009] Preferably, the length of the platform-shaped portion of the second tube is greater than the length of the platform-shaped portion of the first tube.

[0010] Preferably, a first annular baffle is installed on the outer wall of the small opening of the first pipe, and a second annular baffle is installed on the outer wall of the small opening of the second pipe. Each of the first and second annular baffles is located above the liquid in the tank, and a through hole is opened between the first and second annular baffles in the pipeline.

[0011] Preferably, a funnel-shaped feed hopper is provided at the feed inlet, and the feed hopper is fixedly connected to the housing via a connecting rod, and the feed hopper and the pipeline do not come into contact with each other.

[0012] Preferably, a driven wheel is installed at the discharge port, the driven wheel is fixedly connected to the outer wall of the pipe, a motor is installed on the housing, and a driving wheel is installed on the output shaft of the motor through a reducer, the driving wheel and the driven wheel are connected in a transmission manner.

[0013] Preferably, the bottom of the box body has a funnel-shaped structure, an outlet is opened at the lowest point of the bottom of the box body, an inlet is opened on the side wall of the box body, and valves are installed at the inlet and outlet.

[0014] Preferably, a sealing ring is installed at the connection between the pipe and the box body, and each sealing ring is close to the inner wall of the box body and is located above the liquid inside the box body.

[0015] This utility model provides a medicinal material cleaning device for preparing pharmaceutical preparations, which has the following advantages compared with the prior art:

[0016] 1. Through the rotation of the pipes and the propulsion of the spiral blades, the medicinal materials move continuously inside the pipes and come into full contact with the cleaning liquid in the tank.

[0026] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a medicinal material cleaning device for preparing pharmaceuticals, including a tank 1 containing liquid, such as water, suitable cleaning solution. Pipes 2 with different inner diameters are rotatably connected inside the tank 1. A through hole 3 for liquid passage is opened at the lower part of the pipes 2. One end of the pipe 2 extending outside the tank 1 is provided with an inlet 5, and the other end of the pipe 2 extending outside the tank 1 is provided with an outlet 6. This forms a structure where the rotation of the pipe 2 causes the material to move from the inlet 5 to the outlet 6, and the liquid inside the tank 1 cleans the material between the inlet 5 and the outlet 6. In use, the rotation of the pipe 2 relative to the tank 1 causes materials such as medicinal materials for preparing pharmaceuticals to move from the inlet 5 to the outlet 6. During the movement of the material within the pipe 2, it comes into full contact with the liquid inside the tank 1, resulting in thorough cleaning of the medicinal materials. Compared to spray cleaning, the liquid in the tank can clean more medicinal materials, saving water resources.

[0028] In one embodiment, a spiral blade 2.4 is installed inside the pipe 2. The spiral blade 2.4 is welded and fixed to the pipe 2. When the pipe 2 rotates, it drives the spiral blade 2.4 to rotate, so that the material moves with the rotation of the pipe 2. Compared with the traditional stirring and cleaning method, the movement of medicinal materials in the pipe 2 in this device is more stable, which reduces the friction between medicinal materials and between medicinal materials and components, reduces the breakage rate of medicinal materials, and improves the utilization rate of medicinal materials.

[0029] In one embodiment, the pipe 2 includes an intermediate pipe 2.2, one end of which is fixedly connected to a first pipe 2.1, and the other end of which is fixedly connected to a second pipe 2.3. The first pipe 2.1, the second pipe 2.3, and the intermediate pipe 2.2 are an integral structure. The intermediate pipe 2.2 is a columnar structure, which can be a cylindrical structure or a prismatic structure. The first pipe 2.1 and the second pipe 2.3 are frustum-shaped structures, which can be frustum-shaped structures or frustum-shaped structures. The small end of the first pipe 2.1 extends outward to form the feed inlet 5, and the small end of the second pipe 2.3 extends outward to form the discharge outlet 6. The spiral blade 2.4 is located inside the intermediate pipe 2.2 and the second pipe 2.3. After the material enters the pipe 2 through the feed inlet 5, the rotation of the pipe 2 allows the material to move from the small end of the first pipe 2.1 to the large end. At the same time, with the cooperation of the spiral blade 2.4 in the intermediate pipe 2.2 and the second pipe 2.3 and the pipe 2, the material continues to move to the discharge outlet 6.

[0030] In one embodiment, the first pipe 2.1, the second pipe 2.3 and the intermediate pipe 2.2 are coaxial, the axis of the pipe 2 is arranged parallel to the horizontal plane, and the lower part of the intermediate pipe 2.2 is located in the liquid inside the box 1, so as to ensure that the medicinal materials are in full contact with the cleaning liquid inside the box 1 when they move in the pipe 2, thereby improving the cleaning effect.

[0031] In one embodiment, the length of the platform-shaped portion of the second pipe 2.3 is greater than the length of the platform-shaped portion of the first pipe 2.1. The angle between the side of the platform-shaped portion of the first pipe 2.1 and the end face of the large opening can be less than or equal to 45°, and the angle between the side of the platform-shaped portion of the second pipe 2.3 and the end face of the large opening can be greater than or equal to 70°. This allows the material to come into contact with the liquid more quickly after entering from the feed port 5, thereby cleaning it. It also allows the material to move better towards the discharge port 6 on the second pipe 2.3.

[0032] In one embodiment, a first annular baffle 7 is installed on the outer wall of the small-mouth end of the first pipe 2.1, and the first annular baffle 7 is bonded and fixed to the outer wall of the first pipe 2.1. A second annular baffle 8 is installed on the outer wall of the small-mouth end of the second pipe 2.3, and the second annular baffle 8 is bonded and fixed to the outer wall of the second pipe 2.3. The first annular baffle 7 and the second annular baffle 8 are located above the liquid inside the tank 1. A through hole 3 is opened between the first annular baffle 7 and the second annular baffle 8 in the pipe 2. The first annular baffle 7 prevents the liquid from moving towards the small-mouth end of the first pipe 2.1, and the second annular baffle 8 prevents the liquid from moving towards the small-mouth end of the second pipe 2.3. The through hole 3 is opened on the outer wall of the large-mouth end of the first pipe 2.1 and the large-mouth end of the second pipe 2.3. Liquid enters the pipe 2 through the through hole 3 on the outer wall of the end and the side wall of the middle pipe 2.2, thereby contacting the material in the pipe 2. During the rotation of the pipe 2, the material moves from the inlet 5 to the outlet 6, and the material comes into contact with the liquid in the box 1 during the movement. Through the rotation of the pipe 2 and the pushing of the spiral blade 2.4, the material comes into full contact with the cleaning liquid in the box 1, which can remove the dirt and impurities on the surface of the medicinal materials and clean the material between the inlet 5 and the outlet 6. This forms a structure in which the material moves from the inlet 5 to the outlet 6 through the rotation of the pipe 2, and the liquid in the box 1 cleans the material between the inlet 5 and the outlet 6.

[0033] In one embodiment, a funnel-shaped feed hopper 4 is provided at the feed inlet 5. The feed hopper 4 is bolted to the housing 1 via a connecting rod. The feed hopper 4 and the pipe 2 do not contact each other. The feed hopper 4 facilitates the feeding of materials such as medicinal herbs, while avoiding friction between the feed hopper 4 and the pipe 2.

[0034] In one embodiment, a driven wheel 9 is installed at the discharge port 6. The driven wheel 9 is keyed and fixed to the outer wall of the pipe 2. A motor is bolted to the housing 1. The output shaft of the motor is connected to the drive wheel via a reducer. The drive wheel and the driven wheel 9 are connected by a drive transmission. The drive wheel and the driven wheel 9 can be pulleys, and the drive wheel and the driven wheel 9 are connected by a belt drive. Alternatively, the drive wheel and the driven wheel 9 can be gears, and the drive wheel and the driven wheel 9 are connected by a gear drive. Driven by the motor, the pipe 2 is rotated, realizing the automatic conveying and cleaning of medicinal materials. This avoids the time wasted by intermittent operations such as manual feeding and stirring before discharging in traditional cleaning methods, and realizes the continuity of medicinal material cleaning, thereby improving cleaning efficiency.

[0035] In one embodiment, the bottom of the tank 1 is a funnel-shaped structure, and an outlet 10 is opened at the lowest point of the bottom of the tank 1. An inlet 11 is opened on the side wall of the tank 1. Valves 12 are installed at the inlet 11 and the outlet 10 to facilitate the replacement and discharge of liquid in the tank 1, and at the same time, to effectively collect the wastewater after cleaning.

[0036] In one embodiment, a sealing ring 13 is installed at the connection between the pipe 2 and the housing 1. Each sealing ring 13 is close to the inner wall of the housing 1 and is located above the liquid inside the housing 1 to prevent the liquid from leaking from the connection between the pipe 2 and the housing 1.

[0037] Herbal cleaning process: Open valve 12 at inlet 11 and inject an appropriate amount of cleaning solution into tank 1 to ensure that the height of the cleaning solution reaches the appropriate level and that the lower part of intermediate pipe 2.2 is submerged in the cleaning solution. Pour the herbs to be cleaned into pipe 2 through feed hopper 4. Start the motor. The motor drives the drive wheel to rotate through the reducer. The drive wheel drives the driven wheel 9 to rotate through the transmission connection, thereby rotating pipe 2. The spiral blades 2.4 inside pipe 2 rotate with the rotation of pipe 2, pushing the herbs to move from feed inlet 5 to discharge outlet 6 inside pipe 2. During the movement of the medicinal materials, the cleaning solution in the box 1 enters the pipe 2 through the through hole 3 at the bottom of the pipe 2 to clean the medicinal materials and remove dirt, impurities and other contaminants from their surface. The cleaned medicinal materials are discharged from the outlet 6 and fall into the subsequent collection device. When the cleaning solution becomes dirty, the valve 12 at the inlet 11 is closed and the valve 12 at the outlet 10 is opened to discharge the dirty cleaning solution from the box 1. Then the valve 12 at the outlet 10 is closed and the valve 12 at the inlet 11 is reopened to inject new cleaning solution and continue cleaning the medicinal materials.

[0038] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the present invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the present invention, and these should also be considered within the scope of protection of the present invention.
