Description

Technical Field

[0001] This invention belongs to the field of veterinary drug injection production, specifically a liquid mixing device and its processing method for veterinary drug injection production. Background Technology

[0002] Veterinary injectable drugs are a type of veterinary preparation that is injected directly into the animal's body (such as through muscles, veins, or subcutaneous tissue) using a syringe. They are characterized by rapid absorption, rapid efficacy, and high bioavailability. They are mainly used to treat acute diseases, severe infections, or situations where oral administration is not possible. When preparing veterinary injectable drugs, a solution is needed to dissolve the crystalline raw material to form a liquid drug.

[0003] Most existing technologies involve dissolving crystalline pharmaceutical raw materials and solvents in a mixing tank. However, different crystalline raw materials result in liquids with varying densities, which can easily lead to stratification. Furthermore, the liquid formulation inevitably carries residue after formation, requiring filtration. After filtration, residue tends to remain on the filter screen, making it difficult to clean. This residue can be granular or flake-shaped. When the liquid formulation is stirred with a stirring blade, flake-shaped residue remains on the surface. Because these flake-shaped residues carry moisture and have a large contact area with the stirring blade, they are absorbent and difficult to clean.

[0004] Therefore, the present invention provides a mixing device and processing method for producing veterinary injectable drugs. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problems of varying liquid densities after dissolving different crystalline raw materials, which easily lead to stratification, and the inevitable presence of drug residues in the liquid formulation after production, requiring filtration, and the difficulty in cleaning drug residues that remain on the filter screen after filtration, this invention proposes a liquid mixing device and its processing method for the production of veterinary injectable drugs.

One end of each exhaust pipe extends into the interior of the second through groove. The exhaust pipes are arc-shaped. The outer wall of the slide plate has an air inlet that communicates with the first through groove. The outer wall of the slide plate is provided with a drive assembly.

[0010] Preferably, the drive assembly includes a housing, which is fixedly installed on the outer wall of the slide plate and located below the air inlet. A piston plate is slidably connected to the inner wall of the housing, and a piston rod is fixedly connected to one side of the piston plate. One end of the piston rod passes through the housing and is rotatably connected to a connecting shaft. The connecting shaft is rotatably connected to a U-shaped frame.

The first rotating shaft passes through the cover plate.

[0015] A method for manufacturing a veterinary drug injection preparation mixing device, applicable to the aforementioned veterinary drug injection preparation mixing device, comprising the following steps:

[0016] S1: Start the first motor, drive the lead screw to rotate, move the slider downward, move the filter plate downward and into the solution tank, and put the solvent and crystalline raw material into the solution tank;

[0017] S2: Start the second motor to drive the first shaft to rotate, causing the U-shaped frame to rotate, which in turn drives the stirring blades to rotate, stirring the solvent and crystalline raw material.

[0018] S3: After the reagent is dissolved and mixed, the filter plate is moved upward out of the mixing tank by the first motor to filter the reagent in the mixing tank. The third motor is started to drive the cam to rotate, so that the stirring blade and the filter plate vibrate continuously from side to side.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The present invention relates to a mixing device and processing method for producing veterinary injectable drugs. When the stirring blades rotate, the guide vanes rotate within the drug solution. The movement of the guide vanes' arc surface causes the drug solution in the mixing tank to rise and fall, thus preventing stratification. Simultaneously, the U-shaped frame rotates, causing the piston plate to move back and forth, allowing external gas to be blown out along the exhaust pipe. This causes bubbles to rise from the bottom of the drug solution in the mixing tank. The upward movement of the gas facilitates the upward movement of precipitated crystals within the drug solution. This, combined with the stirring of the stirring blades, enhances the dissolution of crystalline raw materials and makes the drug solution more uniform, preventing stratification.

[0021] 2. The present invention discloses a veterinary drug injection preparation mixing device and its processing method. After the drug is dissolved and mixed, the filter plate and stirring blade are moved out of the preparation tank. At this time, the U-shaped frame is rotated again by the second motor, which makes the stirring blade rotate, so as to shake off the drug residue adhering to the stirring blade. Air is blown onto the filter plate through several exhaust pipes to facilitate better cleaning of the drug residue on the filter plate. The cam is rotated by the third motor. Through the cooperation of the cam and the mounting plate, the rotating stirring blade and the filter plate vibrate continuously from side to side, which makes it easier to shake off the drug residue adhering to the stirring blade. In conjunction with the vibration of the filter plate, the drug residue shaken off the stirring blade and the drug residue filtered by the filter plate can slide down the inclined surface of the filter plate. The drug residue that slides down the filter plate is collected by the collection device (such as a garbage can), which facilitates the cleaning of the stirring blade and the filter plate.

[0022] 3. The present invention provides a veterinary drug injection preparation mixing device and its processing method. When gas flows in the first channel, the gas can be heated by an electric heating wire, thereby allowing the hot gas to be discharged into the drug. The influx of hot gas facilitates the dissolution of crystalline raw materials.

[0023] 4. The veterinary drug injection preparation preparation mixing device and its processing method described in this invention, after the filter plate and stirring blade are removed from the preparation tank, hot air is blown out from the exhaust pipe. The hot air impacts the filter plate and flows along the filter plate. After being guided by the arc-shaped surface of the outer wall of the guide block, the hot air flows upward. Thus, while cleaning the filter plate and stirring blade with air, the filter plate and stirring blade are also dried, preventing some flaky drug residue from carrying moisture and adsorbing onto the filter plate and stirring blade, thereby improving the cleaning effect on the filter plate and stirring blade.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figures 1 to 9As shown, the present invention provides a technical solution: a mixing device for producing veterinary injectable drugs, comprising a base 1, a support plate 2 fixedly connected to one side of the base 1, a bracket 3 fixedly connected to the outer wall of the support plate 2, a mixing tank 4 fixedly connected to one side of the bracket 3, a first motor 5 fixedly connected inside the support plate 2, a lead screw 6 fixedly connected to the output end of the first motor 5, the lead screw 6 being rotatably connected to the support plate 2, a slider 7 connected to the outer wall of the lead screw 6 via a lead screw and nut pair, the slider 7 being slidably connected to the support plate 2, a top plate 8 fixedly connected to one side of the slider 7, and the top plate 8... A mounting plate 9 is slidably connected to the bottom, and a sliding plate 18 is fixedly connected to the bottom of the mounting plate 9. The sliding plate 18 fits against the inner wall of the liquid preparation tank 4. A filter plate 19 is fixedly connected to the bottom of the sliding plate 18. The filter plate 19 is installed at an angle. A second motor 10 is fixedly connected inside the mounting plate 9. A first rotating shaft 11 is fixedly connected to the output end of the second motor 10. A U-shaped frame 12 is fixedly connected to the bottom of the first rotating shaft 11. A second rotating shaft 13 is fixedly connected to the bottom of the U-shaped frame 12. A sleeve 14 is fixedly connected to the outer wall of the second rotating shaft 13. A stirring blade 15 is fixedly connected to the outer wall of the sleeve 14.

[0037] Through the above technical solution, the first motor 5 drives the lead screw 6 to rotate, causing the slider 7 to move downward, which in turn moves the top plate 8 downward, the mounting plate 9 downward, and the sliding plate 18 downward, causing the filter plate 19 to move downward and enter the mixing tank 4. The solvent and crystalline raw material are placed into the mixing tank 4, where they dissolve into a medicine. The second motor 10 is then started, driving the first rotating shaft 11 to rotate, which in turn rotates the U-shaped frame 12, which in turn rotates the second rotating shaft 13, causing the sleeve 14 and the stirring blade 15 to rotate, stirring the solvent and crystalline raw material to accelerate the dissolution and mixing of the medicine. After the medicine is dissolved and mixed, the first motor 5 controls the slider 7 to move upward, which in turn moves the mounting plate 9 upward, causing the stirring blade 15 to move upward, which in turn moves the sliding plate 18 and the filter plate 19 upward. The filter plate 19 filters the medicine, removing the residue in the medicine. The remaining medicine passes through the filter plate 19 and remains in the mixing tank 4 for easy access.

[0038] Specifically, two side plates 20 are symmetrically fixedly connected to the top of the filter plate 19, a sliding shaft 25 is fixedly connected to the inner wall of the top plate 8, a connecting block 27 is slidably connected to the outer wall of the sliding shaft 25, the connecting block 27 is fixedly connected to the mounting plate 9, a second spring 26 is sleeved on the outer wall of the sliding shaft 25, one end of the second spring 26 is fixedly connected to the top plate 8, the other end of the second spring 26 is fixedly connected to the connecting block 27, a third motor 28 is fixedly connected to the top of the top plate 8, and the output end of the third motor 28 passes through the top plate 8 and is fixedly connected to a cam 29.

[0039] With the above technical solution, after the filter plate 19 moves upward out of the liquid preparation tank 4, the two side plates 20 facilitate the wrapping of the residue on the filter plate 19. The third motor 28 is started, driving the cam 29 to rotate. When the protruding end of the cam 29 rotates to the side closest to the mounting plate 9, it pushes the mounting plate 9 to the left, causing the connecting block 27 to move to the left, compressing the second spring 26. Simultaneously, as the mounting plate 9 moves to the left, it also drives the stirring blade 15 and the filter plate 19 to move to the left. When the protruding end of the cam 29 rotates away from the mounting plate 9... When the plate 9 is on one side, under the action of the second spring 26, the mounting plate 9 moves back, causing the stirring blade 15 and the filter plate 19 to move back and vibrate. This process repeats. When the cam 29 rotates, it causes the stirring blade 15 and the filter plate 19 to vibrate continuously from side to side. This facilitates the shaking off of the medicine residue adhering to the stirring blade 15. In conjunction with the vibration of the filter plate 19, the medicine residue shaken off the stirring blade 15 and the medicine residue filtered by the filter plate 19 can slide down the inclined surface of the filter plate 19, which facilitates the cleaning of the stirring blade 15 and the filter plate 19.

[0040] Specifically, the inside of the stirring blade 15 is provided with an installation groove 16, and a number of guide vanes 17 are fixedly connected at equal intervals on the inner wall of the installation groove 16. The guide vanes 17 are set in an arc shape.

[0041] With the above technical solution, when the stirring blade 15 rotates, the guide vane 17 rotates inside the agent. Through the movement of the arc surface of the guide vane 17, the agent in the mixing tank 4 floats up and down, thereby avoiding the phenomenon of agent stratification.

[0042] Specifically, the slide plate 18 has a first through groove 30 inside. Two fixed pipes 36 are symmetrically fixedly connected to the outer wall of the slide plate 18 above the filter plate 19. One end of each fixed pipe 36 extends into the interior of the first through groove 30. A second through groove 37 is opened inside the fixed pipe 36. A plurality of exhaust pipes 38 are equidistantly fixedly connected to the outer wall of the fixed pipes 36. One end of each exhaust pipe 38 extends into the interior of the second through groove 37. The exhaust pipes 38 are arc-shaped. An air inlet 31 is opened on the outer wall of the slide plate 18, communicating with the first through groove 30. A drive assembly is provided on the outer wall of the slide plate 18; the drive assembly includes a housing 32. 2. Fixedly installed on the outer wall of the slide plate 18 and located below the air inlet 31, the inner wall of the sleeve 32 is slidably connected to a piston plate 33, and a piston rod 34 is fixedly connected to one side of the piston plate 33. One end of the piston rod 34 passes through the sleeve 32 and is rotatably connected to a connecting shaft 35. The connecting shaft 35 is rotatably connected to the U-shaped frame 12. A first one-way valve 39 is provided inside the first through groove 30 and above the sleeve 32. A second one-way valve 40 is provided inside the exhaust pipe 38. Both the first one-way valve 39 and the second one-way valve 40 open from top to bottom. Several guide plates 41 are fixedly connected at equal intervals inside the second through groove 37. The guide plates 41 are set in an arc shape.

[0043] With the above technical solution, when the end of the U-shaped frame 12 rotates to the left, the connecting shaft 35 pulls the piston rod 34 to the left, causing the piston plate 33 to move to the left. The pulling of the piston plate 33, in conjunction with the first one-way valve 39 and the second one-way valve 40, draws external gas into the casing 32 along the air inlet 31. When the end of the U-shaped frame 12 rotates to the right, the connecting shaft 35 pushes the piston rod 34 to the right, causing the piston plate 33 to move to the right. The squeezing of the piston plate 33, in conjunction with the first one-way valve 39 and the second one-way valve 40, squeezes the gas in the casing 32 along the first through groove 30 into the second through groove 37. Several guide plates 41 guide the second through groove 37... The gas flowing inside is trapped, causing the gas entering the second channel 37 to be discharged along the exhaust pipe 38. This causes the bottom of the medicine in the mixing tank 4 to bubble upwards. The upward surge of gas facilitates the upward movement of the precipitated crystals in the medicine. This, combined with the stirring of the stirring blade 15, improves the dissolution of the crystalline raw material and makes the medicine more uniform, preventing stratification. After the medicine is dissolved and mixed, the filter plate 19 and the stirring blade 15 are moved out of the mixing tank 4. At this time, the U-shaped frame 12 is rotated again by the second motor 10, causing the stirring blade 15 to rotate. This facilitates the removal of the medicine residue adhering to the stirring blade 15. Air is blown onto the filter plate 19 through several exhaust pipes 38 to better clean the medicine residue on the filter plate 19.

[0044] Specifically, a guide block 42 is fixedly connected to the top of the filter plate 19 and between the two fixed tubes 36. Both sides of the guide block 42 are set as arc surfaces, and the top of the guide block 42 is set as a symmetrical inclined surface. An electric heating wire 43 is fixedly connected inside the first through groove 30 and below the sleeve 32.

[0045] Through the above technical solution, while the agent is being stirred, the heating wire 43 is activated. When the gas flows through the first channel 30, the heating wire 43 can heat the gas, thereby allowing the hot gas to be discharged into the agent. The influx of hot gas facilitates the dissolution of the crystalline raw material. After the filter plate 19 and the stirring blade 15 are removed from the liquid preparation tank 4, hot gas is blown out from the exhaust pipe 38. The hot gas impacts the filter plate 19 and flows along the filter plate 19. After being guided by the arc-shaped surface of the outer wall of the guide block 42, the hot gas flows upward. Thus, while cleaning the filter plate 19 and the stirring blade 15 by blowing air, the filter plate 19 and the stirring blade 15 are also dried, preventing some flaky drug residues from carrying moisture and adsorbing onto the filter plate 19 and the stirring blade 15, thereby improving the cleaning effect of the filter plate 19 and the stirring blade 15.

[0046] Specifically, the mounting plate 9 has two symmetrical sliding connections of connecting brackets 23 inside. The top of each connecting bracket 23 is fixedly connected to a limiting block 22. The limiting block 22 is slidably connected to the mounting plate 9. The top of the limiting block 22 is fixedly connected to a first spring 21. The top of the first spring 21 is fixedly connected to the mounting plate 9. The bottom of the connecting bracket 23 is fixedly connected to a cover plate 24. The first rotating shaft 11 passes through the cover plate 24.

[0047] With the above technical solution, when the mounting plate 9 moves downward, it drives the cover plate 24 to move downward. Through the first spring 21, the cover plate 24 is pressed tightly against the top of the liquid mixing tank 4, thereby sealing the top of the liquid mixing tank 4 and preventing the liquid from splashing out during the mixing process.

[0048] A method for manufacturing a veterinary drug injection preparation mixing device, applicable to the aforementioned veterinary drug injection preparation mixing device, comprising the following steps:

[0049] S1: Start the first motor 5, drive the lead screw 6 to rotate, causing the slider 7 to move downward, driving the filter plate 19 to move downward and enter the solution tank 4, and put the solvent and crystalline raw material into the solution tank 4.

[0050] S2: Start the second motor 10, drive the first rotating shaft 11 to rotate, cause the U-shaped frame 12 to rotate, drive the stirring blade 15 to rotate, and stir the solvent and crystalline raw material.

[0051] S3: After the reagent is dissolved and mixed, the filter plate 19 is moved upward out of the liquid preparation tank 4 by the first motor 5 to filter the reagent in the liquid preparation tank 4. The third motor 28 is started to drive the cam 29 to rotate, so that the stirring blade 15 and the filter plate 19 vibrate continuously from left to right.

[0052] In use, the first motor 5 drives the lead screw 6 to rotate, causing the slider 7 to move downwards, which in turn moves the top plate 8 downwards, causing the mounting plate 9 to move downwards, which in turn moves the sliding plate 18 downwards, causing the filter plate 19 to move downwards and enter the mixing tank 4. The solvent and crystalline raw materials are then placed into the mixing tank 4, where they dissolve into a pharmaceutical solution. The second motor 10 is then started, driving the first rotating shaft 11 to rotate, which in turn rotates the U-shaped frame 12, which in turn rotates the second rotating shaft 13, causing the sleeve 14 and the stirring blade 15 to rotate, thus stirring the solvent and crystalline raw materials and accelerating the dissolution and mixing of the pharmaceutical solution. When the mounting plate 9 moves downwards, it causes the cover plate 24 to move downwards, and the first spring 21 keeps the cover plate 24 pressed tightly against the top of the mixing tank 4. This seals the top of the mixing tank 4, preventing splashing of the reagent during mixing. As the stirring blade 15 rotates, the guide vane 17 rotates within the reagent. The arc of the guide vane 17 causes the reagent in the mixing tank 4 to rise and fall, preventing stratification. When the end of the U-shaped frame 12 rotates to the left, the connecting shaft 35 pulls the piston rod 34 to the left, causing the piston plate 33 to move to the left. The pull of the piston plate 33, in conjunction with the first one-way valve 39 and the second one-way valve 40, draws outside gas into the housing 32 through the air inlet 31. When the end of the U-shaped frame 12 rotates to the right, the connecting shaft 35 pushes the piston rod 34 to the right, moving the piston... The piston plate 33 moves to the right, and through the compression of the piston plate 33, in conjunction with the first one-way valve 39 and the second one-way valve 40, the gas in the casing 32 is squeezed along the first channel 30 into the second channel 37. Several guide plates 41 intercept the gas flowing in the second channel 37, causing the gas entering the second channel 37 to be discharged along the exhaust pipe 38. This causes the bottom of the medicine in the mixing tank 4 to bubble upwards. The upward flow of gas facilitates the upward movement of precipitated crystals in the medicine. Combined with the stirring of the stirring blade 15, this improves the dissolution of the crystalline raw material and makes the medicine more uniform, preventing stratification. While stirring the medicine, the heating wire 43 is activated. When the gas flows in the first channel 30, the heating wire 43 can... Gas heating causes hot gas to be released into the pharmaceutical preparation. The influx of hot gas accelerates the dissolution of the crystalline pharmaceutical raw material. After the preparation is dissolved and mixed, the first motor 5 controls the slider 7 to move upward, causing the mounting plate 9 to move upward, which in turn moves the stirring blade 15 upward. This, in turn, moves the sliding plate 18 and filter plate 19 upward. The filter plate 19 filters the pharmaceutical preparation, removing the residue. The remaining pharmaceutical preparation passes through the filter plate 19 and remains in the mixing tank 4 for easy access. At this point, the second motor 10 controls the U-shaped frame 12 to rotate, causing the stirring blade 15 to rotate. This helps to dislodge any residue adhering to the stirring blade 15. Air is also blown onto the filter plate 19 through several exhaust pipes 38 to better clean the residue on the filter plate 19. Hot gas is blown out from the exhaust pipes 38.After the hot air impacts the filter plate 19, it flows along the filter plate 19 and is guided by the arc-shaped surface of the outer wall of the guide block 42, causing the hot air to flow upward. This simultaneously cleans the filter plate 19 and the stirring blades 15 with air and dries them, preventing some of the flaky drug residue from carrying moisture and adsorbing onto the filter plate 19 and stirring blades 15, thus improving the cleaning effect. After removing the filter plate 19 from the liquid preparation tank 4, the third motor 28 is started, driving the cam 29 to rotate. When the protruding end of the cam 29 rotates to the side closest to the mounting plate 9, it pushes the mounting plate 9 to the left, causing the connecting block 27 to move to the left, pressing the second spring 26, and causing the mounting plate 9 to move to the left. Simultaneously, the stirring blade 15 and filter plate 19 move to the left. When the protruding end of the cam 29 rotates to the side away from the mounting plate 9, the mounting plate 9 moves back under the action of the second spring 26, causing the stirring blade 15 and filter plate 19 to move back and vibrate. This process repeats. When the cam 29 rotates, it causes the stirring blade 15 and filter plate 19 to vibrate continuously from side to side. This facilitates the shaking off of the medicinal residue adhering to the stirring blade 15. In conjunction with the vibration of the filter plate 19, the medicinal residue shaken off the stirring blade 15 and filtered by the filter plate 19 can slide down the inclined surface of the filter plate 19. The medicinal residue sliding down the filter plate 19 can be collected by a collection device (such as a trash can), thus facilitating the cleaning of the stirring blade 15 and filter plate 19.
