Description

Technical Field

[0001] This utility model relates to the field of enrofloxacin injection technology, specifically a leak-proof mixing device for injection production. Background Technology

[0002] Enrofloxacin, also known as enrofloxacin carboxylic acid, is a chemically synthesized antibacterial agent belonging to the fluoroquinolone class. The production of enrofloxacin injection requires mixing, necessitating the use of a leak-proof mixing device for injection production.

[0003] For example, a leak-proof mixing device for the production of enrofloxacin injection solution, authorized by publication number "CN 218393340 U", includes a first stirring rod and a second stirring rod. A drive motor rotates the rotating rod, causing both the first and second stirring rods to rotate together, resulting in more uniform mixing and ease of use. However, when mixing the injection solution inside the cylinder using the stirring rods, the mixing area is relatively small, reducing the mixing quality. After the injection solution is mixed and discharged, some solution remains on the inner wall of the cylinder, affecting the mixing effect of the next injection solution and reducing the overall working quality of the device. Utility Model Content

[0004] The purpose of this invention is to solve the problems that when the device stirs and mixes the injection liquid inside the cylinder through the stirring rod, the stirring area is small, which reduces the stirring and mixing quality of the device, and after the injection liquid is mixed and discharged, some injection liquid remains on the inner wall of the cylinder, which affects the mixing effect of the next injection liquid and reduces the working quality of the device. Therefore, a leak-proof mixing device for injection liquid production is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a leak-proof mixing device for injection production, including a base and a cylinder. The cylinder is fixedly connected to the upper end of the base. A wall scraping device is provided at the rear end of the base. A mixing device is provided at the upper end of the cylinder. A feed hopper is fixedly connected to the left side of the upper end of the cylinder. A cover plate is placed on the upper end of the feed hopper. The inner wall of the cylinder is slidably connected to a slider. The upper end of the slider is fixedly connected to a third motor through a bracket. A stirring rod is fixedly connected to the output shaft of the third motor.

[0007] Preferably, the wall scraping device includes a first motor and a first housing. The lower end of the first housing is fixedly connected to the base. The first motor is fixedly connected to the first housing via a bracket. The output shaft of the first motor is rotatably connected to the first housing via a bearing. A turntable is fixedly connected to the output shaft of the first motor. A protrusion is fixedly connected to the outer wall of the turntable. The outer wall of the protrusion is slidably connected to a slide rod. A bent rod is fixedly connected to the upper end of the slide rod. A scraper is fixedly connected to the right end of the bent rod.

[0008] Preferably, the outer wall of the slide rod is slidably connected to the first outer shell, the outer wall of the bent rod is slidably connected to the first outer shell and the cylinder, and the outer wall of the scraper is slidably connected to the inner wall of the cylinder.

[0009] Preferably, the output shaft of the third motor is rotatably connected to the slider via a bearing, the lower end of the base is fixedly connected to a discharge port, and the four corners of the lower end of the base are fixedly connected to support legs.

[0010] Preferably, the mixing device includes a second motor and a second housing. The lower end of the second housing is fixedly connected to the cylinder. The second motor is fixedly connected to the second housing via a bracket. A worm is fixedly connected to the output shaft of the second motor. The outer wall of the worm meshes with a worm wheel. A gear is fixedly connected to the rotating shaft of the worm wheel. The outer wall of the gear meshes with a rack.

[0011] Preferably, the two ends of the worm are rotatably connected to the second housing via bearings, the worm wheel shaft is rotatably connected to the second housing via bearings, the outer wall of the rack is slidably connected to the second housing, and the front end of the rack is fixedly connected to the slider.

[0012] This invention proposes a leak-proof mixing device for injection production. Its advantages lie in the following: Through the cooperation of the mixing device and the stirring rod, the output shaft of the second motor rotates, driving the worm gear. Due to the characteristics of the worm gear, the worm gear rotation drives the worm wheel rotation, which in turn drives the gear rotation synchronously. The gear rotation drives the rack movement, which in turn drives the slider and stirring rod to move synchronously. By controlling the forward and reverse rotation of the second motor's output shaft, the stirring position of the stirring rod is controlled, increasing the stirring area and improving the mixing quality.

[0013] With the cooperation of the wall scraping device and the cylinder, the output shaft of the first motor rotates, driving the turntable to rotate. The rotation of the turntable drives the protrusion to move. As the protrusion moves inside the slide rod, it drives the slide rod to move downward. The slide rod drives the scraper to move synchronously through the bent rod. The scraper scrapes and cleans the mixed solution remaining on the inner wall of the cylinder. The scraped mixed solution is discharged through the discharge port. The operator can use a water gun to clean the inside of the cylinder, reducing the residue of the mixed solution and improving the quality of work. Attached Figure Description

[0026] Working principle:

[0027] The mixing process of the injection solution:

[0028] After the operator pours enrofloxacin injection and sodium hydroxide solution into the feed hopper 5, they cover the feed hopper 5 with the cover plate 6 to prevent leakage of the enrofloxacin injection inside the feed hopper 5. After the enrofloxacin injection and sodium hydroxide solution enter the cylinder 4, the external power supply of the third motor 8 is turned on, and the output shaft of the third motor 8 is started to rotate, driving the stirring rod 9 to rotate and mix the enrofloxacin injection and sodium hydroxide solution inside the cylinder 4. At the same time, the external power supply of the second motor 301 is turned on, and the output shaft of the second motor 301 is started to rotate, driving the worm gear 303 to rotate. Due to the characteristics of the worm gear, the rotation of the worm gear 303 drives the worm wheel 304 to rotate, and the rotation of the worm wheel 304 drives the gear 305 to rotate synchronously. The rotation of the gear 305 drives the rack 306 to move, and the rack 306 drives the slider 7 and the stirring rod 8 to move synchronously. By controlling the forward and reverse rotation of the output shaft of the second motor 301, the stirring position of the stirring rod 8 is controlled, increasing the stirring area and completing the mixing process of the injection.

[0029] Cleaning process of the inner wall of the cylinder:

[0030] After the enrofloxacin injection and sodium hydroxide solution are mixed, they are discharged into the collection container through the discharge port 10. The inner wall of the cylinder 4 will have residual mixed solution. The operator connects the external power supply of the first motor 201 and starts the output shaft of the first motor 201 to rotate, which drives the turntable 203 to rotate. The rotation of the turntable 203 drives the protrusion 204 to move. The protrusion 204 moves inside the slide rod 205 and drives the slide rod 205 to move downward. The slide rod 205 drives the scraper 207 to move synchronously through the bent rod 206. The scraper 207 scrapes and cleans the residual mixed solution on the inner wall of the cylinder 4. The scraped mixed solution is discharged through the discharge port 10. The operator can use a water gun to clean the inside of the cylinder 4. By controlling the above process and repeating the operation, the cleaning process of the inner wall of the cylinder 4 is completed.

[0031] Leakage prevention is achieved through the combination of the cover plate and the feed hopper. The mixing device improves the mixing effect of enrofloxacin injection and sodium hydroxide solution. The combination of the wall scraping device and the cylinder reduces the amount of mixed solution remaining on the inner wall of the cylinder.
