Description

Technical Field

[0001] This utility model relates to the field of powdered veterinary drug technology, and in particular to a dissolving device for powdered veterinary drugs. Background Technology

[0002] Powdered veterinary drugs are veterinary drugs that exist in the form of drug powder. Their advantages are that they are easy to store, transport and prepare. Powdered veterinary drugs usually need to be dissolved in water or other solutions before use so that animals can ingest or treat them. The dissolving device used for powdered veterinary drugs is an auxiliary device specifically designed for dissolving powdered veterinary drugs and liquid solutions.

[0003] In existing dissolving devices used for powdered veterinary drugs, the powder tends to settle at the bottom of the dissolving tank during the dissolving process, resulting in uneven dissolution. At the same time, the powder tends to clump together during the dissolution process, making it difficult for the powder to dissolve completely, thus affecting the absorption and efficacy of the drug.

[0004] Therefore, to address the problems of uneven dissolution and easy agglomeration of powdered veterinary drugs in the aforementioned dissolving devices, this invention sets the stirring blades into an inverted "V" shape. When the stirring blades rotate, they can drive the liquid in the tank to flow along the surface of the stirring blades, forming a continuous circulating flow path. This flow path can continuously agitate the liquid at the bottom of the tank, thereby effectively preventing the powder from settling at the bottom. At the same time, the feeding path of the powdered veterinary drugs is guided to the axial position of the dispersion disc through the feed chute. The centrifugal force of the dispersion disc when it rotates throws the powdered veterinary drugs against the cavity wall of the dissolving tank, thus achieving the effect of impact dispersion of the powdered veterinary drugs.

[0008] Preferably, the accelerated dissolution mechanism includes a positioning support frame, a drive motor, a transmission shaft, stirring blades, and a scraper. The positioning support frame is fixedly installed on the top outer wall of the dissolution tank, and the drive motor is fixedly installed on the top outer wall of the positioning support frame. The output end of the drive motor is connected to the top outer wall of the transmission shaft. The bottom end of the transmission shaft passes through the top outer wall of the dissolution tank and is located inside the dissolution tank. Three sets of stirring blades are fixedly installed at equal intervals on the outside of the transmission shaft located inside the dissolution tank. A scraper is fixedly installed on the side outer wall of the transmission shaft at the bottom position.

[0009] Preferably, the stirring blade is configured as an inverted "V" shape, the outer side wall of the scraper is in contact with the inner side wall of the dissolving tank, and the outer bottom wall of the scraper is in contact with the inner bottom wall of the dissolving tank.

[0010] Preferably, the contact positioning mechanism includes a positioning support ring, a limiting cylinder, a limiting piston rod, a contact spring, and a clamping plate. The positioning support ring is fixedly installed on the top outer wall of the dissolving tank, and the positioning support ring communicates with the internal space of the dissolving tank. Three sets of limiting cylinders are embedded in the inner side wall of the positioning support ring at equal intervals. The limiting piston rod is slidably installed inside the limiting cylinder. A contact spring is installed between the outer side wall of the limiting piston rod and the inner bottom wall of the limiting cylinder. The protruding end of the limiting piston rod is located outside the limiting cylinder, and the protruding end of the limiting piston rod is connected to the outer side wall of the clamping plate. All three sets of clamping plates are located inside the positioning support ring.

[0011] Preferably, all three sets of clamping plates are configured as inverted obtuse-angled "L" shaped structures, and the top outer wall of the clamping plate is configured as an arc-shaped structure. The clamping plate is composed of an upper guiding part and a lower clamping part, and a friction pad is embedded in the inner wall of the side of the clamping plate at the clamping part position.

[0012] Preferably, the limiting cylinder is filled with damping fluid, and a cylindrical through groove is provided circumferentially on the outer side wall of the limiting piston rod located at the piston disc position.

[0013] Preferably, the powder dispersion mechanism includes a guide trough, a dispersion disc, and a retaining ring.

[0015] The beneficial effects of this utility model are:

[0016] 1. The dissolving device used in this powdered veterinary drug uses an inverted "V" shaped stirring blade. When the stirring blade rotates, it drives the liquid in the bucket to flow along the surface of the stirring blade, forming a continuous circulating flow path. This flow path continuously agitates the liquid at the bottom of the bucket, effectively preventing the powder from settling at the bottom. The scraper is designed to scrape and clean the inner wall of the bucket bottom through its circumferential rotation, further preventing the powdered veterinary drug from settling and mixing unevenly.

[0017] 2. The dissolving device used in this powdered veterinary drug guides the powdered veterinary drug to the center of the dispersing disc via a feed chute. The centrifugal force of the rotating dispersing disc throws the powdered veterinary drug against the cavity wall of the dissolving tank. This process achieves an impact dispersion effect, greatly improving the dispersion efficiency of the powder, avoiding the problems of powder agglomeration and incomplete dissolution, ensuring rapid and uniform dissolution of the drug, and thus improving the bioavailability and therapeutic effect of the drug.

[0018] 3. The dissolving device used for this powdered veterinary drug uses an elastic clamping component to invert and hold the powdered veterinary drug bottle during use. This reduces manual intervention while ensuring the normal gravity-based feeding of the powdered veterinary drug, preventing workers from accidentally spilling the powdered veterinary drug outside the device due to hand tremors. It also effectively reduces dust generation when pouring the powdered veterinary drug, reducing the chance of the powdered veterinary drug being accidentally inhaled into the workers' nasal cavity. Overall, it has excellent safety performance. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 This utility model provides a technical solution: a dissolving device for powdered veterinary drugs, including a support base 1 and a dissolving tank 2. The dissolving tank 2 is fixedly installed on the top outer wall of the support base 1. An "L"-shaped liquid inlet pipe is fixedly installed on the side outer wall of the dissolving tank 2 at the middle and upper position, and a liquid inlet hopper is fixedly installed at the liquid inlet end of the liquid inlet pipe. The internal spaces of the dissolving tank 2, the liquid inlet pipe and the liquid inlet hopper are interconnected. A drain pipe is fixedly installed on the side outer wall of the dissolving tank 2 at the bottom position. The internal spaces of the dissolving tank 2 and the drain pipe are interconnected, and a control valve is provided on the outside of the drain pipe.

[0028] The dissolving tank 2 is equipped with an accelerated dissolving mechanism 3, and a contact positioning mechanism 4 is provided above the dissolving tank 2. A powder dispersing mechanism 5 is provided below the contact positioning mechanism 4.

[0029] The accelerated dissolving mechanism 3 includes a positioning support frame 301, a drive motor 302, a transmission shaft 303, stirring blades 304, and scrapers 305. The positioning support frame 301 is fixedly installed on the top outer wall of the dissolving tank 2. The drive motor 302 is fixedly installed on the top outer wall of the positioning support frame 301. The output end of the drive motor 302 is connected to the top outer wall of the transmission shaft 303. The bottom end of the transmission shaft 303 passes through the top outer wall of the dissolving tank 2 and is located inside the dissolving tank 2. Three sets of stirring blades 304 are fixedly installed at equal intervals on the outside of the transmission shaft 303 located inside the dissolving tank 2. Scrapers 305 are fixedly installed on the side outer wall of the transmission shaft 303 at the bottom position. The stirring blades 304 are set as inverted "V" shaped structures. The side outer wall of the scraper 305 is in contact with the side inner wall of the dissolving tank 2, and the bottom outer wall of the scraper 305 is in contact with the bottom inner wall of the dissolving tank 2.

[0030] Because powdered veterinary drugs are prone to sedimentation at the bottom during actual dissolution, the stirring blade 304 is designed as an inverted "V" shape. When the stirring blade 304 rotates, it drives the liquid in the bucket to flow along the surface of the stirring blade 304, forming a continuous circulating flow path. This flow path continuously agitates the liquid at the bottom of the bucket, effectively preventing powder sedimentation. The scraper 305 is designed to scrape and clean the inner wall of the bucket bottom through circumferential rotation, further preventing uneven mixing of powdered veterinary drugs at the bottom.

[0031] The contact positioning mechanism 4 includes a positioning support ring 401, a limiting cylinder 402, a limiting piston rod 403, a contact spring 404, and a clamping plate 405. The positioning support ring 401 is fixedly installed on the top outer wall of the dissolving tank 2, and the positioning support ring 401 communicates with the internal space of the dissolving tank 2. Three sets of limiting cylinders 402 are circumferentially and equally spaced embedded in the inner side wall of the positioning support ring 401. A limiting piston rod 403 is slidably installed inside the limiting cylinder 402. A contact spring 404 is connected between the outer side wall of the limiting piston rod 403 and the inner bottom wall of the limiting cylinder 402. The protruding end of the limiting piston rod 403 is positioned at the limiting... The outer side of the cylinder 402, and the extended end of the limiting piston rod 403 is connected to the side outer wall of the clamping plate 405. All three sets of clamping plates 405 are located inside the positioning support ring 401. The clamping plates 405 are all set as inverted obtuse-angled "L" shaped structures, and the top outer wall of the clamping plate 405 is set as an arc structure. The clamping plate 405 is composed of an upper guide part and a lower clamping part. A friction pad 406 is embedded in the inner side wall of the clamping part of the clamping plate 405. The inside of the limiting cylinder 402 is filled with damping fluid. A cylindrical through groove is circumferentially opened on the outer side wall of the limiting piston rod 403 at the piston plate position.

[0032] The combination of damping fluid and cylindrical channel utilizes the incompressibility of the liquid to allow the damping fluid on one side of the piston plate to overflow through the cylindrical channel to the other side of the piston plate when the limiting piston rod 403 moves. This process achieves a deceleration and protection effect on the limiting piston rod 403, greatly improving the overall durability of the device. The top outer wall of the clamping plate 405 is designed with an arc shape, making it more portable when the veterinary medicine bottle is pushed to the middle position of the three clamping plates 405. The friction pad 406 is designed to increase the contact friction between the device and the outer wall of the veterinary medicine bottle, allowing it to be positioned more stably above the device.

[0033] The powder dispersion mechanism 5 includes a guide trough 501, a dispersion disc 502, and a retaining ring 503. An inclined guide trough 501 is fixedly installed on the inner wall of the top of the dissolving tank 2. The dispersion disc 502 is fixedly installed through the outside of the drive shaft 303. The discharge end of the guide trough 501 faces the axis of the dispersion disc 502. The retaining ring 503 is located directly below the dispersion disc 502 and is connected to the inner wall of the side of the dissolving tank 2. Strip-shaped convex plates are fixedly installed at equal intervals on the outer wall of the top of the dispersion disc 502. The cross-section of the retaining ring 503 is set as a triangular structure, and the lower end face of the retaining ring 503 is set as a cavity structure. The design of multiple sets of strip-shaped convex plates changes the outer wall of the top of the dispersion disc 502 from an initial smooth surface structure to a convex surface structure. By increasing the contact and accommodating surface, the residence time of the powdered veterinary drug on the upper surface of the dispersion disc 502 is extended, thereby extending the feeding contact time for the subsequent dissolving process.

[0034] Working principle: See Figures 1-2 As shown, when it is necessary to dissolve powdered veterinary drugs, the solution must first be poured into the inlet hopper, and then the solution can be automatically injected into the dissolving tank 2 through the guiding effect of the inlet pipe.

[0035] See Figure 3 As shown, the drive motor 302 is then turned on. When the drive motor 302 is turned on, its output end rotates and automatically drives the transmission shaft 303 to rotate, which in turn drives the stirring blade 304 and scraper 305 to rotate synchronously. At this time, the solution inside the dissolving tank 2 is in a dynamic swirling state due to the rotation trajectory of the stirring blade 304 and scraper 305.

[0036] See Figures 4-5As shown, after the above-mentioned dissolving solution is added, the cap of the medicine bottle containing the powdered veterinary drug is unscrewed, and the medicine bottle is pushed upside down to the middle position of the three sets of clamping plates 405. Then, the clamping plates 405 are automatically moved to the side by the pressure of the medicine bottle, providing a certain space for the medicine bottle to be placed. The friction pad 406 is designed to increase the friction between the device and the outer wall of the veterinary drug bottle, so that it can be more stably positioned in the middle position of the three sets of clamping plates 405. When the clamping plates 405 move, they will also automatically drive the limiting piston rod 403 to slide inside the limiting cylinder 402. At this time, the damping fluid on one side of the piston plate passes through the cylindrical groove. The overflow flows to the other side of the piston disc, and in this process, the limiting piston rod 403 is decelerated and protected. At the same time, the contact spring 404 is compressed by the limiting piston rod 403 and is in a contracted state. Furthermore, the contact spring 404 is compressed and generates a reaction force, which will automatically push the limiting piston rod 403 to move in the opposite direction. Then, the limiting piston rod 403 moves in the opposite direction and automatically pushes the clamping plate 405 to move, so that the friction pad 406 is in close contact with the side outer wall of the medicine bottle. In this way, the inverted positioning process of the medicine bottle is realized. Then, the powdered veterinary medicine in the medicine bottle will automatically fall into the interior of the dissolving tank 2 under the action of gravity.

[0037] See Figure 3 and Figure 6 As shown, when the drive shaft 303 rotates, it will automatically drive the dispersion disk 502 to rotate. Then, when the powdered veterinary drug is guided by the feed trough 501, it will automatically fall to the periphery of the axis of the dispersion disk 502. It will be thrown to the cavity wall of the dissolving tank 2 by the centrifugal force when the dispersion disk 502 rotates. This process achieves the effect of impact dispersion of the powdered veterinary drug. Subsequently, the powdered veterinary drug will be guided by the baffle ring 503 and will automatically fall into the dissolving liquid in the lower part of the dissolving tank 2. It will achieve the effect of homogeneous dissolution by the rotation trajectory of the stirring blade 304 and the scraper 305.

[0038] Once the powdered veterinary drug has dissolved completely, opening the control valve outside the outlet pipe will release the dissolved powdered veterinary drug solution from inside the dissolving tank 2 to the outside of the device.

[0039] It should be noted that the aforementioned drive motor 302 can be powered by existing operating techniques, whether using a power supply device or an external wire, both of which are conventional operating techniques and will not be described in detail here.

[0040] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
