Description

Technical Field

[0001] This invention relates to the field of oxytetracycline feeding and drying technology, specifically to an oxytetracycline feeding and drying device. Background Technology

[0002] The oxytetracycline feeding and drying equipment is a closed, inert gas protected drying equipment specifically designed for oxytetracycline raw materials. Its core function is to complete dehydration in a low-oxygen, explosion-proof, and clean environment, while protecting the efficacy of the drug and recovering the solvent. It is one of the common drying equipment for removing liquids from solid materials or products.

[0003] Traditional oxytetracycline feeding and drying equipment may experience insufficient mixing and drying during operation, leading to uneven moisture distribution within the material and locally high moisture content. This can easily cause clumping during the drying process, affecting product quality and subsequent processing. Furthermore, because the protective gas flow rate is usually set to a constant value, it cannot adaptively adjust to dynamic changes in the mixing speed. When the mixing speed decreases, the constant gas flow rate becomes relatively excessive, resulting in waste of protective gas. When the mixing speed increases, the constant gas flow rate becomes relatively insufficient, causing water vapor to fail to escape in time. This creates a saturated humid environment inside the equipment, making it difficult for moisture on the material surface to continue to vaporize, reducing drying efficiency, or even halting the drying process.

[0004] To address the aforementioned issues, we propose a oxytetracycline feeding and drying device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an oxytetracycline feeding and drying device. Through a specially designed stirring structure, the device achieves uniform mixing of materials while continuously scraping the inner wall of the storage container, preventing raw materials from adhering and accumulating. This avoids uneven drying or deterioration caused by localized retention, significantly improving the overall quality of oxytetracycline drying. Furthermore, the device can adjust the amount of protective gas supplied in real time according to the stirring speed. At lower stirring speeds, the gas supply is reduced to avoid waste, while at higher stirring speeds, the gas supply is increased to ensure timely removal of water vapor, thus achieving on-demand supply and efficient utilization of the protective gas.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an oxytetracycline feeding and drying device, comprising a mixing bottom trough block and a sealed top trough block, wherein a mixing horizontal pipe is rotatably installed on both the left and right sides of the inner wall of the mixing bottom trough block, an air-filling pipe is fixedly installed at the left end of the mixing horizontal pipe, and a fixed horizontal bar is rotatably installed at the right end of the mixing horizontal pipe, wherein a combined cylinder is provided at the end of the air-filling pipe and the end of the fixed horizontal bar, wherein a plurality of mixing components are provided on the wall of the fixed horizontal bar, and two connecting rods are symmetrically arranged on one side of the mixing components on the pipe wall of the mixing horizontal pipe, wherein a scraper is fixedly installed at the end of the two connecting rods near the inner wall of the mixing bottom trough block, and an adjusting component is provided on the side of the inner wall of the air-filling pipe near the fixed horizontal bar; The stirring assembly includes a double-toothed block fixedly installed on the wall of a fixed crossbar. Both opposite sides of the double-toothed block are meshed with power bevel gears. A cross-shaped crushing tube is fixedly installed on the surface of each of the two power bevel gears. A connecting cylinder is rotatably installed on the side of the cross-shaped crushing tube wall close to the stirring crossbar. Several crushing toothed tubes are fixedly installed on the surface of the cross-shaped crushing tubes. Multiple drying holes are opened on the wall of each of the crushing toothed tubes.

[0007] Furthermore, the mixing bottom trough block and the sealing top trough block interlock to form a closed horizontal tank structure. The interior of this tank constitutes the mixing and drying space for oxytetracycline. A support frame is fixedly installed at the bottom of the mixing bottom trough block to support the entire tank. A discharge port is provided at one end of the mixing bottom trough block along its length to discharge the dried material. An exhaust pipe is provided at the top of the sealing top trough block to exhaust the water vapor gas generated during the drying process. A feeding port is provided at one end of the sealing top trough block along its length to feed in the oxytetracycline raw material to be dried. A pressure relief valve is also provided at the top of the sealing top trough block to automatically release pressure when the pressure inside the tank exceeds a set value, ensuring the safe operation of the equipment. A circulating condenser is provided at the rear of the mixing bottom trough block. The air inlet of the circulating condenser is connected to the exhaust pipe. The circulating condenser is used to cool and condense the humid gas output from the exhaust pipe, removing the moisture from the gas, and then the dried gas is returned to the tank for recycling. The protective gas used in this equipment is nitrogen. Nitrogen circulates in the closed system to provide an inert protective atmosphere and assist in the discharge of moisture.

[0008] Furthermore, the left end of the stirring horizontal tube extends through and to the outside of the stirring bottom trough block. A power gear plate is fixedly installed on the tube wall on the left side of the stirring bottom trough block. The power gear plate is used to drive the stirring horizontal tube to rotate by connecting with an external drive device.

[0009] Furthermore, one end of the gas-filling pipe passes through and extends into the interior of the stirring horizontal tube, and the gas-filling pipe is fixedly connected to the stirring horizontal tube so that the gas-filling pipe can rotate together with the stirring horizontal tube. The right end of the fixed horizontal bar passes through and extends into the exterior of the stirring bottom trough block, and a fixed seat is fixedly installed on the right end of the fixed horizontal bar. The fixed seat is fixedly connected to the right side of the stirring bottom trough block so that the fixed horizontal bar remains stationary inside the stirring horizontal tube.

[0010] Furthermore, the combined cylinder includes two combined rings and several combined rods. The two combined rings are rotatably connected to the surface of the gas filling pipe and fixedly connected to the surface of the fixed crossbar, respectively, for supporting the fixed crossbar to maintain its stability.

[0011] Furthermore, the horizontal position of several of the scrapers covers the axial length of the inner wall of the mixing bottom trough block. When the mixing horizontal tube rotates, the scrapers are used to scrape off the raw materials attached to the inner wall of the mixing bottom trough block and the sealing top trough block. The portion of the gas-filling pipe extending into the mixing horizontal tube is relatively short, while the portion of the fixed crossbar extending into the mixing horizontal tube is relatively long, and the extension length of the fixed crossbar is close to the entire axial length of the mixing horizontal tube.

[0012] Furthermore, the double-tooth block is composed of two bevel gears arranged back to back. Both opposite sides of the double-tooth block are provided with meshing structures. The two power bevel gears are arranged opposite each other and mesh with the two meshing structures of the double-tooth block respectively. The surface of the connecting cylinder is fixedly connected to the surface of the stirring horizontal tube. The two cross-shaped crushing tubes are inclined relative to the fixed horizontal bar to improve the crushing effect of oxytetracycline. The inner wall of the cross-shaped crushing tube is concentric with the inner wall of the power bevel gear to ensure that the gas in the stirring horizontal tube can smoothly enter the interior of the cross-shaped crushing tube.

[0013] Furthermore, several crushing tooth tubes are staggered, and a check valve is provided at the connection position of each crushing tooth tube and the cross crushing tube to prevent oxytetracycline from flowing back. The line connecting the two connecting rods is perpendicular to the line connecting the two cross crushing tubes. The end of the cross crushing tube extends to the wall of the stirring horizontal tube and is connected to it.

[0014] Furthermore, the adjustment assembly includes a fixed cylinder fixedly installed on one side of the inner wall of the gas filling pipe, a rubber cone fixedly installed on the inner wall of the fixed cylinder, and a plurality of first shaft blocks fixedly installed on the side of the surface of the rubber cone near the fixed crossbar.

A second shaft block is fixedly installed on the side of the centrifuge cylinder near the rubber cone. A pull rod is rotatably installed on the surface of the first shaft block and the surface of the second shaft block. A communication port is opened on the surface of the gas filling pipe inside the telescopic cylinder. A tension spring is fixedly installed on the side of the centrifuge cylinder near the gas filling pipe.

[0015] Furthermore, the narrowed end of the rubber cone is positioned towards the side of the fixed crossbar to accelerate the gas delivery process. Under the action of centrifugal force, the centrifugal cylinder drives the opening of the rubber cone to open, thereby increasing the gas delivery volume. The tube wall of the pull rod extends into the interior of the gas filling pipe through the connecting port, and one end of each of the several tension springs is fixedly connected to the surface of the gas filling pipe.

[0016] Compared with the prior art, the present invention provides an oxytetracycline feeding and drying device, which has the following beneficial effects: 1. This equipment, through its set stirring structure, can achieve uniform mixing of materials while continuously scraping the inner wall of the storage container to prevent raw materials from adhering and accumulating, avoiding uneven drying or deterioration caused by local retention, thus significantly improving the overall quality of oxytetracycline drying.

[0017] 2. The equipment can adjust the amount of protective gas supplied in real time according to the stirring speed. When the stirring speed is low, the gas supply is reduced to avoid waste, and when the stirring speed is high, the gas supply is increased to ensure that water vapor is discharged in time, thereby realizing the on-demand supply and efficient utilization of protective gas.

[0018] 3. During the mixing process, protective gas is introduced simultaneously. The mechanical stirring and the moisture-carrying effect of the gas flow work together to ensure that the material and gas come into more complete contact, the moisture evaporates more quickly, and the drying efficiency is effectively improved.

[0019] 4. Through the synergistic effect of the scraping structure and the stirring mechanism, this equipment effectively reduces material residue on the inner wall of the equipment, lowers the risk of cross-contamination, and ensures the consistency and stability of product quality between different batches.

[0024] The working principle of the above embodiments is as follows: During the operation of the device, the external drive motor drives the stirring tube 3 to rotate through the power gear 301. At the same time, nitrogen gas is continuously input into the stirring tube 3 through the gas filling pipe 4 after being processed by the circulating condenser 204. The operator puts the wet oxytetracycline raw material into the tank through the feeding port 202. When the stirring horizontal tube 3 rotates, it drives the connecting cylinder 704 and the connecting rod 8 to rotate synchronously. The connecting cylinder 704 drives the cross crushing tube 703 to revolve around the fixed horizontal bar 5. At the same time, since the double tooth block 701 is fixed on the stationary fixed horizontal bar 5, the power bevel gear 702 rotates under the meshing action with the double tooth block 701, thereby driving the cross crushing tube 703 and the crushing tooth tube 705 on its surface to rotate around its own axis. Under the combined action of revolution and rotation, the crushing tooth tube 705 fully stirs and crushes the wet oxytetracycline in the tank to prevent the material from agglomerating. At the same time, the connecting rod 8 drives the scraper 9 to rotate along the inner wall of the tank to scrape off the raw materials attached to the inner wall of the stirring bottom trough block 1 and the sealing top trough block 2 to avoid material retention. Nitrogen gas enters the interior of the mixing horizontal tube 3 through the gas filling pipe 4, enters the cross crushing tube 703 through the annular channel between the mixing horizontal tube 3 and the fixed horizontal bar 5, and is then sprayed out through the drying hole 706 of the crushing tooth tube 705. It comes into full contact with the oxytetracycline material in a flowing state, and after carrying moisture, it forms a humid gas. The humid gas enters the circulating condenser 204 through the exhaust pipe 201. After cooling and condensation, the moisture is removed, and the dry nitrogen gas returns to the tank through the gas filling pipe 4, forming a closed loop. When the rotational speed of the stirring tube 3 changes, the centrifuge cylinder 1005 moves radially along the telescopic cylinder 1004 under the action of centrifugal force. When the rotational speed increases, the centrifugal force increases, and the centrifuge cylinder 1005 moves outward. The pull rod 1007 pulls the open end of the rubber cone 1002 outward, which increases the ventilation cross-sectional area of ​​the rubber cone 1002 and the nitrogen input increases accordingly. When the rotational speed decreases, the centrifugal force decreases, and the tension spring 1009 pulls the centrifuge cylinder 1005 back inward. The rubber cone 1002 contracts under its own elasticity, the ventilation cross-sectional area decreases, and the nitrogen input decreases accordingly. Thus, the nitrogen input is dynamically adjusted according to the stirring speed. After drying, the operator opens the discharge port 102, and the finished material is discharged from the tank under the push of the scraper 9 and the action of gravity. The nitrogen output device and connecting pipe of this application are existing mature technologies, and this application will not elaborate on them. An external drive motor drives the stirring horizontal tube 3 to rotate via a power gear 301. The stirring horizontal tube 3 drives the connecting cylinder 704 and the connecting rod 8 to rotate synchronously. The connecting cylinder 704 drives the cross crushing tube 703 to revolve around the axis of the fixed horizontal rod 5. At the same time, since the double tooth block 701 is fixedly installed on the stationary fixed horizontal rod 5, the two power bevel gears 702 generate a rotational motion relative to the cross crushing tube 703 under the meshing action with the double tooth block 701. This rotational motion drives the cross crushing tube 703 and the crushing tooth tube 705 fixed on its surface to rotate around their own axis. Under the combined motion of revolution and rotation, the crushing tooth tube 705 performs multi-dimensional shearing, extrusion and crushing on the wet oxytetracycline material in the tank, effectively breaking up the clumps of material, making the material particles fine and evenly dispersed, creating good heat and mass transfer conditions for subsequent drying. The connecting rod 8 rotates synchronously with the stirring horizontal tube 3, driving the scraper 9 fixed at its end to make a circular motion along the inner wall of the stirring bottom trough block 1 and the sealing top trough block 2. The outline of the scraper 9 matches the shape of the inner wall of the tank, which can continuously scrape off the material adhering to the inner wall, preventing the material from drying unevenly, overheating and denaturing or scaling due to long-term retention, ensuring that all materials participate in the drying process, improving drying uniformity and product quality. The regulating component 10 achieves dynamic matching between nitrogen input and stirring speed. When the stirring tube 3 rotates, the centrifuge cylinder 1005 moves radially along the telescopic cylinder 1004 under the action of centrifugal force. The magnitude of the centrifugal force is proportional to the square of the rotation speed. Therefore, the displacement of the centrifuge cylinder 1005 is positively correlated with the rotation speed of the stirring tube 3. The centrifuge cylinder 1005 pulls the open end of the rubber cone 1002 through the pull rod 1007, changing the ventilation cross-sectional area of ​​the rubber cone 1002. When the rotation speed increases, the centrifugal force increases, the opening of the rubber cone 1002 expands, and the nitrogen input increases. When the rotation speed decreases, the centrifugal force decreases, the tension spring 1009 pulls the centrifuge cylinder 1005 to reset, the rubber cone 1002 contracts, and the nitrogen input decreases. This regulating mechanism enables the nitrogen input to automatically adapt to changes in stirring intensity. More gas is provided to enhance drying when the rotation speed is high and the material is violently agitated, and the gas supply is reduced at low rotation speed to avoid waste. When nitrogen gas is ejected through the drying hole 706 of the crushing tooth tube 705, it forms multiple fine airflows that are directly injected into the material being stirred and agitated by the crushing tooth tube 705. Because the crushing tooth tube 705 is in motion, its jet position is constantly changing, allowing the nitrogen gas to fully and evenly contact the material. During the contact process between the nitrogen gas and the material, the nitrogen gas carries water vapor from the surface of the material, forming a humid gas. The humid gas enters the circulating condenser 204 through the exhaust pipe 201, where it is cooled to below the dew point. The water vapor condenses into liquid water and is then discharged. The dried nitrogen gas re-enters the circulation. Through continuous circulation, the moisture in the material is continuously removed from the tank until the target degree of dryness is achieved.
