Description

Technical Field

[0001] This invention relates to the field of substance dissolution technology, and in particular to a device for dissolving sparingly soluble substances. Background Technology

[0002] Insoluble substances are compounds with extremely low solubility in water or common solvents, commonly found in the pharmaceutical, chemical, and materials industries. The difficulty in dissolving these substances is mainly due to factors such as dense crystal structure, low molecular polarity, or high surface energy.

[0003] Traditional dissolution techniques mostly rely on mechanical stirring or heating equipment to improve dissolution efficiency. However, solid materials have a passivation layer on their surface, resulting in low efficiency of traditional dissolution methods. To address these issues, this invention proposes a device for dissolving sparingly soluble substances. Summary of the Invention

[0004] This invention provides a device for dissolving sparingly soluble substances, which solves the problem that existing technologies rely on mechanical stirring or heating equipment to improve dissolution efficiency, but the solid material has a passivation layer on its surface, resulting in low efficiency of traditional dissolution methods.

[0005] This invention provides the following technical solution:

[0006] A device for dissolving sparingly soluble substances includes a dissolving tank and a top cover fixed to the top of the dissolving tank by bolts. A lower pressure plate is fixedly connected to the bottom inner wall of the dissolving tank. A stirring shaft is provided inside the dissolving tank, and an upper pressure plate that cooperates with the lower pressure plate is fixedly connected to the bottom of the stirring shaft.

[0007] A drive mechanism is provided at the bottom of the top cover to drive the stirring shaft to rotate and move up and down to grind the raw materials.

[0008] An inflation mechanism is provided at the bottom of the dissolving tank for inflating the tank with air.

[0009] Furthermore, the driving mechanism includes a driving shaft and two driving plates. The driving shaft is rotatably connected to the top of the top cover and passes through the top cover. A sleeve is slidably fitted on the bottom of the driving shaft. Two symmetrically arranged driving rods are rotatably connected to the outer wall of the sleeve. The driving plates are all fixed to the inner wall of the top of the top cover and cooperate with the driving rods respectively. The driving plates are arc-shaped and each has a bevel at one end. A tension spring is fixed between the bottom of the sleeve and the driving shaft by a hook. An installation sleeve is fixedly connected to the bottom of the driving sleeve. The top of the stirring shaft slides through the bottom of the installation sleeve and is fixedly connected to a positioning plate. A first spring is installed between the positioning plate and the inner wall of the top of the installation sleeve by a spring seat.

[0010] Furthermore, the drive mechanism also includes a motor, with one end of the motor output shaft fixed to the drive shaft.

[0011] Furthermore, the inflation mechanism includes a central tube that is fixedly inserted through one side of the dissolving tank. One end of the central tube is fixedly connected to a circular air outlet pipe, which is located inside the dissolving tank and has multiple evenly distributed nozzles fixedly connected to its top and bottom.

[0012] Furthermore, the inflation mechanism also includes two fixed cylinders, both of which are fixed to the top of the top cover and penetrate the top cover. A one-way air outlet valve is fixed to the top of each fixed cylinder. A bent pipe is fixed between the air outlet ends of the two one-way air outlet valves. One side of the bent pipe is fixedly connected to the middle pipe. A one-way air inlet valve is fixedly installed on one side of each fixed cylinder. A piston is slidably connected inside each fixed cylinder. An L-shaped pull bracket is fixedly connected to the bottom of each piston. The pull bracket slides through the bottom of the fixed cylinder and one end of each pull bracket is located below the mounting sleeve. A second spring is installed between the piston and the bottom inner wall of the fixed cylinder through a spring seat.

[0013] Furthermore, the air outlet pipe is inclined, and one of the nozzles is located at the lowest point of the air outlet pipe for draining liquid.

[0014] Furthermore, a through-feed pipe is fixed to the top of the dissolving tank, and a cover plate is provided on the top of the feed pipe.

[0015] Furthermore, a through water injection pipe is fixed to the top of the dissolving tank, and a discharge pipe is fixed to one side of the dissolving tank. Both the discharge pipe and the water injection pipe are equipped with control valves at one end.

[0016] Furthermore, multiple stirring blades are fixedly installed around the circumference of the stirring shaft.

[0017] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0018] In this invention, the upper pressure plate and the lower pressure plate work together to rotate and move up and down, thereby squeezing and rubbing the raw material, which can destroy the passivation layer or oxide film on the surface of the solid particles, and thus grind the raw material into smaller particles and improve the dissolution efficiency.

[0019] In this invention, by using a second spring to push the upper pressure plate downward, the upper pressure plate can avoid hard contact with the lower pressure plate during use, thus preventing damage to the stirring shaft and improving the service life of the equipment.

[0020] In this invention, by installing an air outlet pipe inside the dissolving tank, with air outlet nozzles installed at both the top and bottom of the air outlet pipe, the generated bubbles produce turbulence and shear force as they rise in the liquid, reducing local concentration saturation, preventing particle agglomeration, and significantly improving dissolving efficiency.

[0021] In this invention, by installing the air outlet pipe at an angle, the residual liquid in the air outlet pipe can be discharged along the nozzle at the lowest point during material discharge, thus avoiding material accumulation.

[0022] In this invention, the raw materials can be squeezed and rubbed, thereby destroying the passivation layer or oxide film on the surface of solid particles, and then grinding the raw materials into smaller particles, improving the dissolution efficiency. At the same time, it avoids hard contact between the upper pressure plate and the solid particles, improving the service life of the parts. Furthermore, the turbulence and shear force generated when bubbles rise in the liquid reduce local concentration saturation, prevent particle agglomeration, and significantly improve the dissolution efficiency.

Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0032] References to "one embodiment" or "some embodiments" as used in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the invention. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0033] In one embodiment, reference is made to... Figures 1-5 A device for dissolving sparingly soluble substances includes a dissolving tank 1 and a top cover 2 fixed to the top of the dissolving tank 1 by bolts. A lower pressure plate 10 is fixedly connected to the bottom inner wall of the dissolving tank 1. A stirring shaft 7 is provided inside the dissolving tank 1. An upper pressure plate 9 that works with the lower pressure plate 10 is fixedly connected to the bottom of the stirring shaft 7. The upper pressure plate 9 can move up and down and rotate, thereby squeezing and rubbing the raw material, thereby destroying the passivation layer or oxide film on the surface of the solid particles, and thus grinding the raw material into smaller particles and improving the dissolution efficiency.

[0034] The drive mechanism 11 is located at the bottom of the top cover 2 and is used to drive the stirring shaft 7 to rotate and move up and down to grind the raw materials.

[0035] An inflation mechanism 12 is provided at the bottom of the dissolving tank 1 for filling the dissolving tank 1 with air.

[0036] In this invention, the drive mechanism 11 includes a drive shaft 13 and two drive plates 21. The drive shaft 13 is rotatably connected to the top of the top cover 2 and passes through the top cover 2. A sleeve 14 is slidably fitted on the bottom of the drive shaft 13. Multiple guide strips are fixed around the circumference of the drive shaft 13 and slide with the sleeve 14, thereby preventing the drive shaft 13 from spinning freely. Two symmetrically arranged drive rods 16 are rotatably connected to the outer wall of the sleeve 14. The drive plates 21 are all fixed to the top inner wall of the top of the top cover 2 and cooperate with the drive rods 16 respectively. The drive plates 21 are arc-shaped and each has a bevel 22 at one end. A tension spring 17 is fixed between the bottom of the sleeve 14 and the drive shaft 13 by a hook. The bottom of the drive sleeve 15 is fixedly connected to the mounting sleeve 18. The top of the stirring shaft 7 slides through the bottom of the mounting sleeve 18 and is fixedly connected to the positioning plate 19. The top of the stirring shaft 7 is also provided with a guide strip for guiding. After the mounting sleeve 18 is driven, the stirring shaft 7 is rotated. The positioning plate 19 and the top inner wall of the mounting sleeve 18 are connected by a spring seat and a first spring 20 is installed. When the drive rod 16 moves to the plane of the drive plate 21, the drive sleeve 15 drives the first spring 20 to move downward, thereby pushing the stirring shaft 7 to move downward, and at the same time driving the upper pressure plate 9 downward. The upper pressure plate 9 and the lower pressure plate 10 squeeze the raw material, and at the same time rotate to rub the raw material.

[0037] It should be noted that the drive mechanism 11 also includes a motor 3. One end of the output shaft of the motor 3 is fixed to the drive shaft 13, and the motor 3 is used to drive the drive shaft 13 to rotate.

[0038] In another embodiment, refer to Figures 1-5 An improved device for dissolving sparingly soluble substances was developed based on Example 1.

[0039] In this invention, the aeration mechanism 12 includes a central tube 30, which is fixedly inserted through one side of the dissolving tank 1. One end of the central tube 30 is fixedly connected to a circular air outlet pipe 31. The air outlet pipe 31 is located inside the dissolving tank 1 and has multiple uniformly distributed nozzles 32 fixedly connected to its top and bottom. Air is discharged into the dissolving tank 1 through the air outlet pipe 31 and the nozzles 32. When air bubbles are formed in the liquid and rise, turbulence and shear force are generated, reducing local concentration saturation, avoiding particle agglomeration, and significantly improving dissolution efficiency.

[0040] In particular, the inflation mechanism 12 also includes two fixed cylinders 23, both of which are fixed to the top of the top cover 2 and penetrate through the top cover 2. A one-way air outlet valve 28 is fixed to the top of each fixed cylinder 23. A bent pipe 29 is fixed between the air outlet ends of the two one-way air outlet valves 28. One side of the bent pipe 29 is fixedly connected to the intermediate pipe 30. A one-way air inlet valve 27 is fixedly installed on one side of each fixed cylinder 23. A piston 24 is slidably connected inside each fixed cylinder 23. An L-shaped pull bracket 26 is fixedly connected to the bottom of each piston 24. 26 slides through the bottom of the fixed cylinder 23 and one end is located below the mounting sleeve 18. The piston 24 and the bottom inner wall of the fixed cylinder 23 are both equipped with a second spring 25 through a spring seat. When the mounting sleeve 18 moves downward, it also pushes the pull bracket 26 to move downward. The pull bracket 26 drives the piston 24 to move downward. Air enters the fixed cylinder 23 through the one-way air intake valve 27. When the mounting sleeve 18 moves upward, the piston 24 moves upward under the action of the second spring 25, thereby pushing the air into the intermediate tube 30.

[0041] It should be noted that the air outlet pipe 31 is inclined, and one of the nozzles 32 is located at the lowest point of the air outlet pipe 31 for draining liquid. During the discharge process, the residual liquid in the air outlet pipe 31 can be discharged along the nozzle 32 at the lowest point, thus avoiding the accumulation of material.

[0042] In this invention, a through feed pipe 4 is fixed to the top of the dissolving tank 1, and a cover plate is provided on the top of the feed pipe 4. The feed pipe 4 is used to add solid raw materials. A through water injection pipe 5 is fixed to the top of the dissolving tank 1. The water injection pipe 5 is used to add liquid raw materials. A discharge pipe 6 is fixed to one side of the dissolving tank 1. The dissolved raw materials can be discharged through the discharge pipe 6. A control valve is provided at one end of both the discharge pipe 6 and the water injection pipe 5.

[0043] It should be noted that multiple stirring blades 8 are fixedly installed on the circumference of the stirring shaft 7. The rotation of the stirring shaft 7 drives the stirring blades 8 to rotate, and the stirring blades 8 mix the raw materials.

[0044] However, as is well known to those skilled in the art, the working principle and wiring method of motor 3 are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0045] The working principle and usage process of this technical solution are as follows: During use, raw materials are added to the dissolving tank 1 through the feed pipe 4 and water injection pipe 5. Simultaneously, the motor 3 is started. The motor 3 drives the drive shaft 13, sleeve 14, drive sleeve 15, and stirring shaft 7 to rotate. The stirring shaft 7 drives the stirring blades 8 to rotate, thus mixing the raw materials. Under the action of rotation, some solid raw materials are concentrated in the middle part of the bottom of the dissolving tank 1. When the drive sleeve 15 rotates, it drives the drive rod 16 to rotate along the drive plate 21. The drive rod 16 is located on the inclined surface 2 at the bottom of the drive plate 21. When the stirring shaft 7 and the bottom upper pressure plate 9 move upward under the action of the tension spring 17, a gap is formed between the upper pressure plate 9 and the lower pressure plate 10, allowing some solid raw materials to enter. When the drive rod 16 moves to the plane of the drive plate 21, the drive sleeve 15 drives the first spring 20 to move downward, thereby pushing the stirring shaft 7 downward and simultaneously driving the upper pressure plate 9 downward. The upper pressure plate 9 and the lower pressure plate 10 squeeze the raw materials, and at the same time, the rotation rubs the raw materials, destroying the passivation layer or oxide film on the surface of the solid particles, thereby grinding the raw materials into smaller particles and improving the dissolution efficiency.

[0046] When the mounting sleeve 18 moves downward, it also pushes the pull bracket 26 downward. The pull bracket 26 drives the piston 24 downward. Air enters the fixed cylinder 23 through the one-way air inlet valve 27. When the mounting sleeve 18 moves upward, the piston 24 moves upward under the action of the second spring 25, which pushes the air into the intermediate tube 30. Then, it is discharged into the dissolving tank 1 through the air outlet pipe 31 and the nozzle 32. When bubbles are formed in the liquid and rise, turbulence and shear force are generated, reducing local concentration saturation, avoiding particle agglomeration, and significantly improving dissolution efficiency.

[0047] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
