Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a mixing and stirring device used in pharmaceutical workshops. Background Technology

[0002] Pharmaceutical workshops are facilities specifically designed for drug production. Their design and operation must comply with strict Good Manufacturing Practice (GMP) standards to ensure the quality, safety, and efficacy of drugs. Pharmaceutical workshops are typically divided into clean areas and general production areas. Clean areas use air conditioning systems and air filtration facilities to control the number of dust particles and microorganisms, ensuring a dust-free and sterile production environment. Pharmaceutical workshops can be used to produce raw materials for antibiotics, chemically synthesized drugs, biochemical drugs, phytochemical drugs, and various pharmaceutical preparations or traditional Chinese medicine preparations.

[0003] In existing technology, during the pharmaceutical processing and production of drugs, it is necessary to mix the raw materials of the drug solution, which requires the use of mixing and stirring equipment. However, most mixing and stirring equipment makes it inconvenient to clean the inner wall of the mixing tank when mixing the raw materials of the drug solution. This may cause the drug solution to adhere to the inner wall of the mixing tank, resulting in local concentrations that are too high or too low. Furthermore, the drug solution residue will dry and form dirt. In addition, cleaning the inside of the mixing tank when not in use is quite troublesome.

[0004] Therefore, a device for mixing and stirring in pharmaceutical workshops is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a mixing and stirring device for pharmaceutical workshops, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A mixing and stirring device for a pharmaceutical workshop includes a base plate with legs at its bottom and a mixing tank at its top. A cylinder is mounted on the top of the base plate, and a lid is attached to the telescopic end of the cylinder, with the mixing tank fitting snugly against the lid. The lid has a water spraying mechanism for conveniently spraying water into the mixing tank. A stirring rod is mounted on the water spraying mechanism, and a brushing mechanism for cleaning the inner wall of the mixing tank is mounted on the stirring rod. The lid has a drive mechanism for providing rotational power. The brushing mechanism includes a connecting frame fixedly mounted on the outer wall of the stirring rod. A slot is formed on the surface of the connecting frame, and a cleaning brush is slidably mounted on the inner wall of the slot, contacting the mixing tank. Three locking pins are threaded onto the connecting frame and the cleaning brush.

[0008] Furthermore, the number of cylinders is set to two, which are symmetrically distributed.

[0009] Furthermore, the water spraying mechanism includes a connecting pipe, which is rotatably mounted on the bucket lid. A limiting component is fixedly mounted on the top of the bucket lid, and the connecting pipe is rotatably mounted on the limiting component. A fixing pipe is fixedly mounted on the limiting component, and the connecting pipe is rotatably mounted on the outer wall of the fixing pipe. A sprayer is fixedly mounted on the bottom of the connecting pipe, and a stirring rod is fixedly mounted on the bottom of the sprayer.

[0010] Furthermore.

[0011] Furthermore.

[0012] Furthermore, the driving mechanism includes a first gear, which is fixedly installed on the outer wall of the connecting pipe. A U-shaped plate is fixedly installed on the top of the bucket lid. A motor is provided on the surface of the U-shaped plate. A second gear is provided at the output end of the motor, and the first gear meshes with the second gear.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention, through the arrangement of a water spraying mechanism, a drive mechanism, and a wall-brushing mechanism, allows for efficient operation. During use, the raw materials to be mixed are placed inside the mixing tank. The drive mechanism is then activated, causing the water spraying mechanism, stirring rod, and wall-brushing mechanism to rotate. The stirring rod mixes the raw materials, while the wall-brushing mechanism cleans the tank walls, removing any adhering liquid and ensuring uniform distribution of the liquid components. This prevents localized high or low concentrations and improves the mixing effect. When cleaning is required after use, the water spraying mechanism is connected to the water supply system, and the drive mechanism is activated again to operate the water spraying mechanism. The stirring rod and brushing mechanism rotate to clean the tank. When the cleaning parts in the brushing mechanism become worn, the cylinder can be activated to lift the lid, causing the water spraying mechanism, stirring rod, and brushing mechanism to move upwards. The cleaning parts can then be replaced by releasing the fixing parts inside the brushing mechanism. After replacement, the cylinder can be activated again to reset the lid, ensuring it fits tightly against the mixing tank. This achieves cleaning of the mixing tank walls during the mixing process, reducing the adhesion of the medicine, and automatically cleaning the inside of the mixing tank, the stirring rod, and the brushing mechanism. It is simple to operate and highly practical. Attached Figure Description

[0025] like Figure 1-4As shown, a mixing and stirring device for a pharmaceutical workshop includes a base plate 1, with support legs 2 at the bottom of the base plate 1, a mixing tank 3 at the top of the base plate 1, a cylinder 4 at the top of the base plate 1, a tank cover 5 at the telescopic end of the cylinder 4, and the mixing tank 3 fitting snugly to the tank cover 5. The tank cover 5 has a water spraying mechanism 6 for conveniently spraying water into the mixing tank 3, a stirring rod 7 on the water spraying mechanism 6, a wall-brushing mechanism 8 on the stirring rod 7 for cleaning the inner wall of the mixing tank 3, and a drive mechanism 9 on the tank cover 5 for providing rotational power. The wall-brushing mechanism 8 includes a connecting frame. 801. A connecting frame 801 is fixedly installed on the outer wall of the stirring rod 7. A slot is provided on the surface of the connecting frame 801, and a cleaning brush 802 is slidably installed on the inner wall of the slot, and the cleaning brush 802 is in contact with the stirring tank 3. Locking pins 803 are threadedly installed on the connecting frame 801 and the cleaning brush 802, and the number of locking pins 803 is set to three. In this embodiment, during use, the raw materials of the medicine to be mixed are placed inside the stirring tank 3, and then the drive mechanism 9 is activated to drive the water spraying mechanism 6, the stirring rod 7, and the brush wall mechanism 8 to rotate. The stirring rod 7 stirs and mixes the raw materials of the medicine. The brushing mechanism 8 cleans the walls of the mixing tank 3, removing any adhering medication and ensuring even distribution of the medication components. This prevents localized high or low concentrations and improves mixing efficiency. When cleaning is required after use, the water spraying mechanism 6 is connected to the water supply system, and the drive mechanism 9 is activated. This rotates the water spraying mechanism 6, the stirring rod 7, and the brushing mechanism 8 for cleaning. If any cleaning components in the brushing mechanism 8 become worn, the cylinder 4 can be activated to lift the tank lid 5, causing the water spraying mechanism 6, the stirring rod 7, and the brushing mechanism 8 to move upwards. The cleaning mechanism can be further cleaned by releasing the internal fixing components of the brushing mechanism 8. Once fixed, the cleaning components can be replaced. After replacement, the cylinder 4 is activated to reset the lid 5, which fits tightly against the mixing tank 3. This allows for brushing and cleaning of the mixing tank 3 walls during the mixing process, reducing the adhesion of the medicine. It can also automatically clean the inside of the mixing tank 3, the mixing rod, and the brushing mechanism. The operation is simple and highly practical. The slot design facilitates the installation and positioning of the cleaning brush 802. When the mixing rod 7 rotates, the cleaning brush 802 moves along the circumference to clean the inner wall of the mixing tank 3. The locking pin 803 facilitates the locking connection between the connecting frame 801 and the cleaning brush 802.

[0026] like Figure 1 As shown, the number of cylinders 4 is set to two, which are symmetrically distributed. In this embodiment, the stability of lifting the bucket lid 5 is enhanced by setting the number of cylinders 4.

[0027] like Figure 1-3As shown, the water spraying mechanism 6 includes a connecting pipe 601, which is rotatably mounted on the bucket cover 5. A limiting member 603 is fixedly mounted on the top of the bucket cover 5, and the connecting pipe 601 is rotatably mounted on the limiting member 603. A fixing pipe 604 is fixedly mounted on the limiting member 603, and the connecting pipe 601 is rotatably mounted on the outer wall of the fixing pipe 604. A sprayer 602 is fixedly mounted on the bottom of the connecting pipe 601, and a stirring rod 7 is fixedly mounted on the bottom of the sprayer 602. In this embodiment, the fixing pipe 604 is connected to the water supply component pipeline. When the water supply component supplies water to the fixing pipe 604, the water will flow from the connecting pipe 601 into the sprayer 602 and spray into the mixing tank 3. When the connecting pipe 601 rotates, it can drive the sprayer 602 to rotate, spraying water into the mixing tank 3 in a rotating manner.

[0028] like Figure 1-3 As shown, the drive mechanism 9 includes a gear 901, which is fixedly installed on the outer wall of the connecting pipe 601. A U-shaped plate 902 is fixedly installed on the top of the bucket cover 5. A motor 903 is provided on the surface of the U-shaped plate 902. A gear 904 is provided at the output end of the motor 903. The gear 901 and the gear 904 mesh with each other. In this embodiment, when the motor 903 is started, the gear 904 is driven to rotate, and the gear 901 rotates in the opposite direction, which in turn drives the connecting pipe 601 to rotate. Therefore, the sprayer 602 and the stirring rod 7 rotate accordingly.

[0029] In summary, during use, the raw materials to be mixed are placed inside the mixing tank 3. Then, the drive mechanism 9 is activated, which rotates the water spray mechanism 6, the stirring rod 7, and the wall brushing mechanism 8. The stirring rod 7 stirs and mixes the raw materials, while the wall brushing mechanism 8 cleans the walls of the mixing tank 3, removing the adhering liquid and ensuring uniform distribution of the liquid components. This avoids local concentrations that are too high or too low, improving the mixing effect. If cleaning is required when not in use, the water spray mechanism 6 is connected to the water supply component pipe, and the drive mechanism 9 is activated again, rotating the water spray mechanism 6, the stirring rod 7, and the wall brushing mechanism 8 for cleaning. When the cleaning components in the wall brushing mechanism 8 become worn, the cylinder 4 is activated to lift the tank lid 5, causing the water spray mechanism 6, the stirring rod 7, and the wall brushing mechanism 8 to move upwards. The cleaning components can be replaced by releasing the fixed parts inside the wall brushing mechanism 8. After replacement, the cylinder 4 is activated again to reset the tank lid 5, ensuring a tight fit with the mixing tank 3. This achieves the desired cleaning effect during the mixing process. The mixing tank 3 features a brushed wall cleaning system to reduce the adhesion of the cleaning solution. It automatically cleans the interior of the mixing tank 3, the mixing rod, and the brushing mechanism. Operation is simple and highly practical. The number of cylinders 4 is adjusted to enhance the stability of the lid 5 during lifting. Connected to the water supply component via a fixed pipe 604, when the water supply component supplies water to the fixed pipe 604, the water flows through the connecting pipe 601 into the sprayer 602, spraying it into the mixing tank 3. Rotating the connecting pipe 601 drives the sprayer 602 to rotate, further cleaning the mixing tank. The internal rotating water sprayer of the tank 3 has a slot for easy installation and positioning of the cleaning brush 802. When the stirring rod 7 rotates, the cleaning brush 802 moves in a circle to clean the inner wall of the mixing tank 3. The locking pin 803 facilitates the locking connection between the connecting frame 801 and the cleaning brush 802. The motor 903 is started, which drives the gear 2 904 to rotate. The gear 1 901 rotates in the opposite direction and drives the connecting pipe 601 to rotate. Therefore, the sprayer 602 and the stirring rod 7 rotate accordingly.
