Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical preparation stirring technology, and in particular to a stirring device. Background Technology

[0002] Pharmaceutical formulation mixing refers to the process of uniformly mixing solid and liquid raw materials using specific equipment and methods during the preparation of pharmaceutical formulations. Its main purpose is to ensure uniform distribution of drug components and guarantee the consistency of formulation quality and efficacy. During mixing, solid and liquid raw materials can fully contact and blend, stabilizing the properties of the formulation.

[0003] However, during storage and transportation, solid raw materials are prone to forming lumps of varying sizes due to factors such as humidity and pressure. When these lumps enter the feed pipe of the mixing device, they can only fall under their own weight due to the lack of effective crushing methods. As production continues, the uncrushed lumps accumulate in the feed pipe, gradually forming blockages. This prevents the raw materials from smoothly entering the mixing area, forcing production to be interrupted. Workers then need to spend a lot of time clearing and unblocking, reducing production efficiency.

[0004] Therefore, there is an urgent need to propose a stirring device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a stirring device to solve the problem that solid raw materials tend to accumulate and clog the feed pipe during feeding, thus affecting production efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A stirring device for stirring pharmaceutical preparations, comprising:

[0008] A mixing tank is provided with a mixing chamber, a liquid inlet and a discharge outlet, wherein the liquid inlet and the discharge outlet are respectively connected to the mixing chamber;

[0009] A feed pipe is vertically installed at the top of the mixing tank and connected to the mixing chamber; the inner wall of the feed pipe is provided with a guide groove.

[0011] The stirring assembly includes a first stirring element and a second stirring element. The first stirring element is connected to the rotating element and located in the stirring chamber. The second stirring element is rotatably connected to the transmission element and its end is inserted into the guide groove. The motor can drive the rotating element to rotate the first stirring element. When the rotating element rotates, it can push the transmission element to move up and down reciprocally through the bottom of the annular groove. The second stirring element can spirally rise and fall along the guide groove under the drive of the transmission element.

[0012] Preferably, the transmission component includes a first connecting rod, a second connecting rod, and a sliding rod connected vertically in sequence, with the first connecting rod and the sliding rod located on opposite sides of the second connecting rod, the first connecting rod located within the annular groove, and the second stirring component rotatably connected to the sliding rod.

[0013] Preferably, the stirring device further includes a positioning member, one end of which is connected to the inner wall of the stirring chamber, and the other end is provided with a limiting hole, through which the sliding rod passes.

[0014] Preferably, the stirring device further includes an elastic element, which is sleeved on the outer surface of the sliding rod and located between the second connecting rod and the positioning element.

The fixed frame is located inside the receiving cavity and is fixedly connected to the rotating frame. The rotating paddle is fixedly connected to the fixed frame. The nozzle is located outside the rotating frame and communicates with the receiving cavity. Water sprayed from the water inlet pipe can impact the rotating paddle, causing the rotating paddle to rotate and driving the rotating frame to rotate around the water inlet pipe.

[0018] Preferably, the stirring device further includes a discharge pipe, which is inserted through the discharge port.

[0019] Preferably, a valve is provided on the discharge pipe.

[0020] Preferably, the stirring device further includes a base, and the stirring tank is disposed on the base.

[0021] The beneficial effects of this utility model are:

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1-5As shown, this utility model provides a stirring device for stirring pharmaceutical preparations, including a stirring tank 1, a feed pipe 2, a drive assembly 3, and a stirring assembly 4. The stirring tank 1 is provided with a stirring chamber 100, a liquid inlet, and a discharge outlet, which are respectively connected to the stirring chamber 100. The feed pipe 2 is vertically arranged at the top of the stirring tank 1 and connected to the stirring chamber 100, and the inner wall of the feed pipe 2 is provided with a guide groove 20. The drive assembly 3 includes a motor 31, a rotating component 32, and a transmission component 33. The motor 31 is located at the top of the stirring tank 1, and the rotating component 32 is located inside the stirring chamber 100, connected to the output end of the motor 31, and has a top surface opening. The assembly has an annular groove 320, and the transmission component 33 is inserted vertically into the annular groove 320. The stirring assembly 4 includes a first stirring component 41 and a second stirring component 42. The first stirring component 41 is connected to the rotating component 32 and is located in the stirring chamber 100. The second stirring component 42 is rotatably connected to the transmission component 33 and its end is inserted into the guide groove 20. The motor 31 can drive the rotating component 32 to drive the first stirring component 41 to rotate. When the rotating component 32 rotates, it can push the transmission component 33 to move up and down reciprocally through the bottom of the annular groove 320. The second stirring component 42 can spirally rise and fall along the guide groove 20 under the drive of the transmission component 33.

[0039] A single motor 31 drives the rotating component 32 to rotate, synchronously driving the first stirring component 41 to rotate, thereby achieving thorough mixing of solid and liquid raw materials within the mixing chamber 100. Simultaneously, the drive component 33 reciprocates up and down within the annular groove 320, causing the second stirring component 42 to spirally rise and fall along the guide groove 20 of the feed pipe 2. This allows for the stirring and crushing of solid raw materials as they enter the feed pipe 2, effectively preventing large solid particles from caking and clogging the feed pipe 2, ensuring smooth feeding. Furthermore, this stirring device requires only a single motor power source to achieve the dual functions of crushing, feeding, and mixing, featuring a compact structure, low energy consumption, anti-clogging properties, and high working efficiency.

[0040] In this embodiment, the rotating component 32 is a cylinder with an annular groove 320. When the motor 31 drives the rotating component 32 to rotate, the change in the height of the bottom of the annular groove 320 is transmitted to the transmission component 33 through the contact surface. The transmission component 33 contacts the rising slope of the bottom of the groove and is gradually lifted up; the transmission component 33 contacts the descending slope of the bottom of the groove and slides down due to gravity or spring reset. For each rotation of the rotating component 32, the transmission component 33 completes one lifting and lowering reciprocating motion.

[0041] Specifically, such as Figure 1 and Figure 2 As shown, the stirring device also includes a liquid inlet pipe 14, which passes through the liquid inlet. The liquid inlet pipe 14 provides a stable channel for the liquid raw material to enter the stirring chamber 100, preventing the liquid raw material 14 from splashing at the liquid inlet.

[0042] In this embodiment, both the top of the feed pipe 2 and the liquid inlet pipe 14 are covered with sealing caps. The sealing caps can effectively prevent external dust, foreign objects and other impurities from entering the feed pipe 2 and the liquid inlet pipe 14, avoiding them from mixing into the raw materials, thereby ensuring the quality of the raw materials fed into the stirring device and preventing impurities from adversely affecting the quality of the drug preparation, such as affecting the purity and stability of the drug or causing adverse reactions.

[0043] Specifically, the mixing device also includes a discharge pipe 12, which is installed at the discharge port. The discharge pipe 12 can guide the mixed agent to flow out in a specific direction, preventing the agent from flowing or splashing randomly at the discharge port, ensuring that the material can accurately enter the designated position, which helps to improve the standardization and orderliness of the production process.

[0044] More specifically, a valve 121 is installed on the discharge pipe 12. When the stirring device finishes stirring a batch of drug preparations, the valve 121 can be opened to discharge the drug; when it is necessary to pause, the valve 121 can be closed to stop immediately, which is convenient for production personnel to operate according to the actual production rhythm.

[0045] Specifically, the mixing device also includes a base 13, on which the mixing tank 1 is mounted. During operation, the mixing component 4 generates a continuous mixing force, which can easily cause the mixing tank 1 to shake or shift. The base 13 can effectively disperse the force transmitted from the mixing tank 1, stably fixing it in the working position, preventing the shaking of the mixing tank 1 from affecting the mixing effect, and ensuring the safe operation of the equipment.

[0046] Specifically, such as Figure 2 As shown, the first stirring component 41 includes a stirring shaft 411 and a stirring paddle 412. The stirring shaft 411 is connected to the rotating component 32, and the stirring paddle 412 is disposed on the stirring shaft 411.

[0047] More specifically, at least two stirring paddles 412 are provided, and the stirring paddles 412 are spaced apart along the length direction of the stirring shaft 411.

[0048] In this embodiment, two stirring paddles 412 are provided, each stirring paddle 412 includes four blades, and the four blades are arranged circumferentially around the stirring shaft 411.

[0049] In other embodiments, three stirring paddles 412 may be provided, each stirring paddle 412 may include five blades, and no specific limitation is made here on the stirring paddles 412 and the number of blades in each stirring paddle 412.

[0050] Specifically, such as Figure 2 and Figure 3As shown, the second stirring element 42 includes a rotating base 421 and at least two stirring rods 422. The rotating base 421 is rotatably connected to the transmission element 33. The stirring rods 422 are spaced apart around the rotating base 421, and one end of the stirring rod 422 away from the rotating base 421 is inserted into the guide groove 20. Multiple stirring rods 422 simultaneously perform spiral lifting and lowering movements at different positions within the feed pipe 2, enabling more comprehensive and frequent crushing and clearing of the solid raw materials within the feed pipe 2.

[0051] In this embodiment, the rotating seat 421 is fitted around the rotating disk 334 and can rotate relative to the rotating disk 334.

[0052] In this embodiment, four stirring rods 422 are provided, and the four stirring rods 422 are evenly distributed around the rotating base 421.

[0053] In other embodiments, five stirring rods 422 may be provided, and the number of stirring rods 422 is not specifically limited here.

[0054] More specifically, the second stirring element 42 also includes a cutting block 423, which is vertically disposed on the stirring rod 422. For some larger solid raw materials, the cutting block 423 can cut and crush them like a blade during rotation, breaking down the large solid raw materials into smaller particles, thereby effectively preventing solid raw materials from clogging the feed pipe 2.

[0055] In this embodiment, four cutting blocks 423 are provided, and the four cutting blocks 423 are respectively arranged on the four stirring rods 422.

[0056] In other embodiments, eight cutting blocks 423 may be provided, with an average of two cutting blocks 423 on each stirring rod 422. The number of cutting blocks 423 is not specifically limited here.

[0057] In this embodiment, the cutting block 423 is a triangular prism with sharp edges, which can cut larger solid raw materials.

[0058] Specifically, such as Figure 3 and Figure 4 As shown, the transmission component 33 includes a first connecting rod 331, a second connecting rod 332, and a sliding rod 333 connected vertically in sequence. The first connecting rod 331 and the sliding rod 333 are located on opposite sides of the second connecting rod 332. The first connecting rod 331 is located within the annular groove 320. The second stirring component 42 is rotatably connected to the sliding rod 333. The first connecting rod 331, the second connecting rod 332, and the sliding rod 333 can be manufactured as independent components. The shape and structure of each component are relatively simple, facilitating large-scale production using standardized production processes and molds.

[0059] In other embodiments, the transmission component 33 may also be manufactured as a single piece.

[0060] In this embodiment, the transmission component 33 further includes a rotating disk 334, which is connected to the end of the sliding rod 333 away from the second connecting rod 332. The second stirring component 42 is fitted around the rotating disk 334 and can rotate relative to the rotating disk 334.

[0061] In other embodiments, the rotating disk 334 may be omitted, and the rotational connection may be achieved through a bearing. A bearing is installed at the end of the sliding rod 333, and the second stirring element 42 is interference-fitted with the outer ring of the bearing and the inner ring of the bearing is interference-fitted with the sliding rod 333. When the transmission element 33 moves, the second stirring element 42 can rotate relative to the sliding rod 333 with the help of the rolling elements of the bearing.

[0062] More specifically, the stirring device also includes a positioning element 5, one end of which is connected to the inner wall of the stirring chamber 100, and the other end is provided with a limiting hole, through which the sliding rod 333 passes. During the operation of the transmission element 33, the sliding rod 333, constrained by the limiting hole, can only move up and down along the axial direction of the limiting hole, effectively avoiding the unstable situations such as shaking and deviation that may occur when the transmission element 33 moves up and down reciprocatingly, and ensuring that the second stirring element 42 can always accurately spiral up and down along the guide groove 20.

[0063] In this embodiment, the positioning element 5 includes a positioning rod and a positioning block. The positioning rod is fixedly connected to the inner wall of the mixing chamber 100, and the positioning block is a cylinder connected to the end of the positioning rod away from the inner wall of the mixing chamber 100. The positioning block is provided with the aforementioned limiting hole.

[0064] More specifically, such as Figure 4 As shown, the stirring device also includes an elastic element 6, which is sleeved on the outer surface of the sliding rod 333 and located between the second connecting rod 332 and the positioning element 5. When the sliding rod 333 moves upward, it can compress the elastic element 6; when the sliding rod 333 moves downward, the elastic element 6 can release its elastic potential energy, assisting the sliding rod 333 in resetting downward.

[0065] In this embodiment, the transmission component 33 further includes a connecting block 335, which is disposed on the second connecting rod 332. The sliding rod 333 is disposed on the top of the connecting block 335, and the elastic element 6 is located between the connecting block 335 and the positioning block. The larger planes of the connecting block 335 and the positioning block can better contact the elastic element 6, keeping the elastic element 6 stable during compression and rebound, and preventing the elastic element 6 from shifting or twisting during operation.

[0066] In this embodiment, the elastic element 6 is a spring.

[0067] In other embodiments, the elastic element 6 may also be a rubber block.

[0068] Specifically, such as Figure 1 and Figure 5 As shown, the stirring device also includes a water inlet pipe 7, a rotating frame 8, a fixed frame 9, a rotating paddle 10, and a nozzle 11. The water inlet pipe 7 extends into the stirring chamber 100. The rotating frame 8 is located inside the stirring chamber 100, fitted onto the outer surface of the water inlet pipe 7, and can rotate relative to the water inlet pipe 7. The rotating frame 8 is provided with a receiving cavity 80, and part of the water inlet pipe 7 extends into the receiving cavity 80. The fixed frame 9 is located inside the receiving cavity 80 and is fixedly connected to the rotating frame 8. The rotating paddle 10 is fixedly connected to the fixed frame 9. The nozzle 11 is located outside the rotating frame 8 and communicates with the receiving cavity 80. The water sprayed from the water inlet pipe 7 can impact the rotating paddle 10, causing the rotating paddle 10 to rotate and drive the rotating frame 8 to rotate around the water inlet pipe 7.

[0069] After the mixing device completes its mixing operation, the mixing chamber 100 needs to be cleaned. At this time, the water inlet pipe 7 continuously supplies water, and the water flow impacts the rotating paddle 10, causing the rotating paddle 10 to drive the rotating frame 8 to rotate around the water inlet pipe 7, which in turn drives the nozzle 11 to rotate and spray water. This allows for a comprehensive and thorough cleaning of the inner wall of the mixing chamber 100, the mixing components 4, and other parts, improving cleaning efficiency and quality, reducing the workload of manual cleaning, and effectively preventing residual raw materials from contaminating the next batch of pharmaceutical preparations.

[0070] The water inlet pipe 7, the rotating frame 8, the fixed frame 9, the rotating paddle 10, and the nozzle 11 constitute a set of cleaning components. In this embodiment, in order to improve the cleaning effect, two sets of cleaning components are provided.

[0071] In this embodiment, a positioning ring is fitted on the outer surface of one end of the water inlet pipe 7 that extends into the accommodating cavity 80, and the rotating frame 8 is fitted on the outer surface of the water inlet pipe 7 and abuts against the positioning ring, thereby realizing the rotational connection between the rotating frame 8 and the water inlet pipe 7.

[0072] In other embodiments, a protrusion may be provided on the outer surface of the water inlet pipe 7, and a connecting channel communicating with the accommodating cavity 80 may be provided on the rotating frame 8. The inner wall of the connecting channel is provided with an annular groove. The water inlet pipe 7 passes through the connecting channel, and the protrusion is inserted into the annular groove. The cooperation between the protrusion and the annular groove allows the rotating frame 8 to rotate smoothly around the water inlet pipe 7.

[0073] In this embodiment, the fixing frame 9 is a cross, which is horizontally arranged and its four ends are fixedly connected to the inner wall of the accommodating cavity 80.

[0074] In this embodiment, the rotating paddle 10 includes a rotating shaft and multiple arc-shaped blades. The rotating shaft is connected to the center of the fixed frame 9, and the multiple arc-shaped blades are evenly arranged around the rotating shaft, which can effectively convert the impact force of the water flow into the rotational torque.

[0075] In this embodiment, multiple nozzles 11 are provided and are located at the bottom of the rotating frame 8. When the rotating frame 8 rotates, the multiple nozzles 11 spray water simultaneously, increasing the water flow rate and water pressure per unit time. This allows for more powerful rinsing away of stubbornly attached materials, providing stronger cleaning power and ensuring cleaning quality.

[0076] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
