[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figures 1 to 9 As shown, a dissolving and stirring device for producing medium- and long-chain fat emulsion injection comprises a base 1, a support plate 2 symmetrically fixedly connected to the surface of the base 1, and a stirring drum 3 fixedly connected to the surface of the support plate 2. A feed pipe 4 and a discharge pipe 5 are fixedly connected to the surface of the stirring drum 3, respectively. The feed pipe 4 is located above the discharge pipe 5. A sealing cover 6 is fixedly connected to the surface of the stirring drum 3 via a first bolt.

[0031] The surface of the sealing cover 6 is provided with a dissolving and stirring assembly 7, which includes an L-shaped plate 71 fixedly connected to the surface of the sealing cover 6, a driving motor 72 fixedly mounted on the surface of the L-shaped plate 71, and a first rotating rod 73, a stirring blade 74 and a heating tube 75 for dissolving and stirring the medium- and long-chain fat emulsion injection. The stirring blade 74 stirs the different components in the solution to fully mix them. The power provided by the driving motor 72 can ensure that the stirring liquid moves rapidly, thereby driving the various molecules in the medium- and long-chain fat emulsion injection to accelerate their movement. The increase in the molecular movement speed makes the collisions between them more frequent, which is conducive to the faster diffusion of the solute molecules into the solvent, thereby accelerating the dissolution process.

[0032] An auxiliary component 8 is fixedly installed between the base 1 and the mixing drum 3. The auxiliary component 8 includes a hollow cylinder 820 symmetrically fixedly connected to the base 1, an air outlet pipe 824 fixedly connected between the hollow cylinder 820 and the mixing drum 3, and a movable plate 88 for blowing air into the mixing drum 3, a telescopic slide rod 89, a first spring 810, an air bag 811, a first tooth plate 813, a mounting frame 814, a first gear 815, a second tooth plate 816, a connecting plate 819, a first slide rod 821 and a piston 822. By synchronously and intermittently blowing air into the solution, bubbles can be formed in the solution. The process of the bubbles rising and bursting will generate local turbulence, which works together with the stirring to further enhance the mixing degree of different components in the solution.

[0033] Example 2

[0034] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0035] The first rotating rod 73 is rotatably connected to the sealing cover 6, and the top of the first rotating rod 73 is fixedly connected to the output shaft of the driving motor 72. A plurality of stirring blades 74 are fixedly connected to the surface of the first rotating rod 73 at equal intervals, and the stirring blades 74 can fully stir the injection liquid.

[0036] The inner wall of the mixing drum 3 is fixedly connected with a plurality of heating tubes 75 at equal intervals. Heating the injection solution by the heating tubes 75 further enhances the thermal motion of the molecules. The temperature rises, which increases the kinetic energy of the molecules in the solution and accelerates the diffusion rate. This cooperates with the stirring effect to greatly improve the dissolution efficiency.

[0037] Example 3

[0038] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0039] The surface of the base 1 is symmetrically fixedly connected with a telescopic slide 89, the top of the telescopic slide 89 is fixedly connected with a movable plate 88, an air bag 811 is fixedly connected between the movable plate 88 and the base 1, and first springs 810 are fixedly connected on both sides of the air bag 811 between the movable plate 88 and the base 1, and first tooth plates 813 are fixedly connected on both sides of each movable plate 88. A mounting bracket 814 is symmetrically fixedly connected at a position near each first tooth plate 813 on the surface of the base 1, and a first gear 815 is rotatably connected between the two mounting brackets 814 through a first rotating shaft. The first gear 815 is meshed with the first tooth plate 813, and the side of the first gear 815 away from the first tooth plate 813 is meshed. The second tooth plate 816 is connected to the joint, and the surface of the second tooth plate 816 is fixedly connected to the connecting plate 819, and the bottom surface of the connecting plate 819 is fixedly connected to the first sliding rod 821. The first sliding rod 821 is slidingly connected to the hollow cylinder 820, and the interior of the hollow cylinder 820 is slidingly connected to the piston 822. The bottom end of the first sliding rod 821 extends to the interior of the hollow cylinder 820 and is fixedly connected to the piston 822. The surface of the hollow cylinder 820 is fixedly connected to the air inlet pipe 823 near its bottom. During the stirring process, the reciprocating squeezing airbag 811 allows the hollow cylinder 820 to intermittently blow air into the solution, and the airflow can be used to drive the solution to stir, thereby improving the dissolution and mixing quality efficiency.

[0040] It should be noted that: a one-way valve is provided inside the air inlet pipe 823 and the air outlet pipe 824 respectively to ensure that the air inlet pipe 823 and the air outlet pipe 824 can flow in and out in one direction;

[0041] One end of the air outlet pipe 824 placed in the mixing drum 3 is tilted downward, which can reduce the probability of solution backflow.

[0042] A support column 817 is fixedly connected to the surface of the base 1 near each second tooth plate 816, and a T-block 818 is fixedly connected to the surface of each support column 817. The T-block 818 is slidably connected to the second tooth plate 816 and can limit the position of the second tooth plate 816.

[0043] A connecting tube 812 is fixedly connected between the two airbags 811, which enables the gas in the two airbags 811 to be exchanged. When one airbag 811 contracts, it can cause the other airbag 811 to collide, thereby achieving intermittent blowing.

[0044] The surface of the first rotating rod 73 is fixedly sleeved with the first bevel gear 81, and the surface of the first bevel gear 81 is symmetrically meshed with the second bevel gear 82. The surface of each second bevel gear 82 is fixedly connected to the third rotating rod 83, and the surface of each third rotating rod 83 is rotatably connected to the U-shaped plate 85. The U-shaped plate 85 and the sealing cover 6 are fixedly connected. The surface of the mixing drum 3 is symmetrically rotatably connected to the fourth rotating rod 86, and a belt connecting mechanism 84 is fixedly connected between the third rotating rod 83 and the fourth rotating rod 86. The end of each fourth rotating rod 86 is fixedly connected to a cam 87, and the cam 87 and the movable plate 88 are slidably connected. The blowing work is realized by the power of the driving motor 72. The linkage between stirring and blowing can speed up the production process and shorten the production time of the medium and long chain fat emulsion injection. The two cooperate with each other to achieve uniform mixing and chemical reaction of the solution more quickly, reduce waiting time and energy consumption, which can improve the production capacity of the production line and reduce production costs for large-scale production.

[0045] It should be noted that the belt connection mechanism 84 includes a large pulley, a small pulley and a belt body, wherein the large pulley is fixedly connected to the fourth rotating rod 86, the small pulley is fixedly connected to the third rotating rod 83, and the large pulley and the small pulley are connected through the belt body transmission.

[0046] Working principle: When using this dissolving and stirring device to stir the medium and long chain fat emulsion injection, first fix the sealing cover 6 to the surface of the stirring drum 3 by the first bolt, and close the valve of the discharge pipe 5, and then add the production raw materials into the stirring drum 3 through the feed pipe 4. After the addition is completed, the drive motor 72 can be started to run. The operation of the drive motor 72 can drive the first rotating rod 73 to rotate, and the rotation of the first rotating rod 73 then drives the stirring blade 74 to rotate, so that the stirring blade 74 can stir the mixed liquid. The power provided by the drive motor 72 can ensure that the stirring liquid moves quickly, thereby driving the various molecules in the medium and long chain fat emulsion injection to accelerate the movement. The increase in the molecular movement speed makes the collisions between them more frequent, which is conducive to the solute molecules to diffuse into the solvent faster, thereby accelerating the dissolution process.

[0047] During this process, the heating tube 75 is started to operate synchronously, and the heating tube 75 heats the solution so that the solution is at a suitable temperature. The heating by the heating tube 75 further enhances the thermal motion of the molecules. The temperature rises, which increases the kinetic energy of the molecules in the solution and accelerates the diffusion speed. This, together with the stirring effect, greatly improves the dissolution efficiency.

[0048] At the same time, the operation of the driving motor 72 can drive the first bevel gear 81 to rotate, the first bevel gear 81 rotates and then drives the second bevel gear 82 to rotate, the second bevel gear 82 rotates and then drives the third rotating rod 83 to rotate on the surface of the U-shaped plate 85, the third rotating rod 83 rotates and then drives the belt connecting mechanism 84 to rotate, the belt connecting mechanism 84 rotates and then drives the fourth rotating rod 86 to rotate, the fourth rotating rod 86 rotates and then drives the cam 87 to rotate, and the cam 87 rotates while it rotates. It can intermittently squeeze the movable plate 88 so that the movable plate 88 can be reciprocated and lifted. In this process, when the cam 87 presses the movable plate 88, the movable plate 88 can be lifted and lowered. At 8, the movable plate 88 moves downward, at this time the movable plate 88 drives the first tooth plate 813 to move downward, the first tooth plate 813 moves downward and then drives the first gear 815 to rotate through the meshing action, the first gear 815 rotates and then drives the second tooth plate 816 to move upward, the second tooth plate 816 moves upward and then can drive the first slide bar 821 to move upward in the hollow cylinder 820 through the connecting plate 819, the first slide bar 821 moves upward and then can drive the piston 822 to move upward, the piston 822 moves upward and then can allow external air to enter the hollow cylinder 820 through the intake pipe 823 for storage, when the cam 87 leaves the movable plate 88, the surface of the movable plate 88 is opened. When the dough is mixed, the movable plate 88 moves upward under the elastic force of the first spring 810, and the movable plate 88 moves upward, which in turn drives the first tooth plate 813 to move upward. The first tooth plate 813 moves upward, and then drives the first gear 815 to rotate through the meshing action. The first gear 815 rotates and then drives the second tooth plate 816 to move downward. The second tooth plate 816 moves downward and can drive the first slide bar 821 to move downward in the hollow cylinder 820 through the connecting plate 819. The first slide bar 821 moves downward and can drive the piston 822 to move downward. The piston 822 moves downward and can allow the air in the hollow cylinder 820 to enter the mixing cylinder through the outlet pipe 824. 3, thereby blowing air into the mixed solution in the mixing drum 3. By intermittently blowing air into the solution, bubbles can be formed in the solution. The process of bubble rise and bursting will produce local turbulence, which works together with stirring to further enhance the mixing degree of different components in the solution. Stirring mainly makes the solution flow through mechanical force, while the bubble disturbance caused by blowing promotes mixing from another dimension, making the various components in the medium and long chain fat emulsion injection more evenly distributed. This multi-dimensional mixing method can effectively reduce the stirring dead angle, ensure that every part of the solution can be fully stirred, and improve the consistency of the product.
