Description

Technical Field

[0001] This utility model relates to the field of heating devices, specifically a heating device for a liquid mixing tank. Background Technology

[0002] The preparation tank, also known as the mixing tank or dispensing tank, is a key piece of equipment in pharmaceutical production. It is mainly used for the preparation, mixing, dissolving, and diluting of liquid formulations to ensure that the drug components are uniform and the concentration is accurate.

[0003] In the existing technology, when preparing medicines by mixing liquids, the inner wall of the tank is generally equipped with a spiral coil. The heating medium circulates in the coil to conduct heat to heat the medicine. However, during use and observation, it was found that the solid material in the tank is denser than the solvent and tends to settle to the bottom of the tank. At the same time, due to the limited heating capacity of the coil, the bottom is prone to insufficient heating, which in turn affects the dissolution process of the material at the bottom.

[0004] Therefore, a liquid mixing tank heating device is proposed to address the above problems. Utility Model Content

[0022] 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 scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1 to 5As shown in the figure, a liquid mixing tank heating device according to an embodiment of the present invention includes a tank body 1, the top of which is connected to an inlet 12; the bottom of which is connected to an outlet 13; a motor 14 is fixedly connected to the top of the tank body 1; a rotating shaft 15 is fixedly connected to the output end of the motor 14; the rotating shaft 15 and the tank body 1 are through-connected and rotatably connected; multiple sets of stirring blades 16 are fixedly connected to the outer wall of the rotating shaft 15; a first heating coil 17 and a second heating coil 18 are fixedly connected to the inner wall of the tank body 1 from top to bottom; both the first heating coil 17 and the second heating coil 18 are spiral structures, and the first heating coil... The pitch of the first heating coil 17 is greater than that of the second heating coil 18; a pressure relief valve 19 is installed on the top of the tank 1; during operation, solid materials and solvents can be added into the tank 1 by opening the valve at the inlet 12, and the rotating shaft 15 is driven to rotate by starting the motor 14. The rotating shaft 15 will drive multiple sets of stirring blades 16 to rotate together and mix the materials in the tank 1. When it is necessary to remove the liquid medicine from the tank 1, the valve at the outlet 13 can be opened. During the mixing and preparation process, the materials in the tank 1 need to be heated. Specifically, one end of the first heating coil 17 and the second heating coil 18 are connected to the medium supply equipment, and the medium is heated by the delivery pump. The heating medium is transported, driving it to circulate within the first heating coil 17 and the second heating coil 18. During this process, the heating medium heats the material inside the tank 1 through heat conduction. After heating, the medium can be discharged from the other end of the first heating coil 17 and the second heating coil 18 and reheated by the heating components. This cycle can then be repeated to circulate and heat the material inside the tank 1. The pressure relief valve 19 ensures stable air pressure inside the tank 1. The first heating coil 17 and the second heating coil 18 are two separate circulation systems. Therefore, during the preparation of the medicine solution, the medium supply in the second heating coil 18 can be greater than that in the first heating coil 18. Heating coil 17, i.e., the first heating coil 17, is responsible for preheating the liquid medicine, while the second heating coil 18 is responsible for the main heating of the liquid medicine. This avoids local overheating in the tank 1 and achieves differentiated heating of the liquid medicine in the tank 1. It is worth mentioning that the valve structures involved in the above-mentioned inlet 12, outlet 13, and pressure relief valve 19 are mature existing technologies, so they will not be described in detail here. By setting the first heating coil 17 and the second heating coil 18, materials at different heights in the tank 1 can be heated separately, reducing local overheating or insufficient heat energy, thereby improving the uniformity of component dissolution and distribution during the preparation of the liquid medicine in the tank 1.

[0025] Please see Figure 4 and Figure 5As shown, a connecting pipe 22 is fixedly connected to the top of the tank 1; an air inlet pipe 23 is connected to one side of the connecting pipe 22; the rotating shaft 15 and the connecting pipe 22 are connected through each other and rotatably; multiple air inlets are opened on the outer wall of the rotating shaft 15 located inside the connecting pipe 22; multiple air bladders 2 are fixedly connected to the outer wall of the rotating shaft 15; multiple air outlets are opened on the outer wall of the rotating shaft 15 located inside the air bladders 2, and the rotating shaft 15 and the air bladders 2 are connected; during the preparation of the medicine liquid in the tank 1, the air inlet pipe 23 can be connected to an air pump, so that the airflow can enter the connecting pipe 22 through the air inlet pipe 23 and rotate through the air pump. Air enters the interior of the rotating shaft 15 through the air inlet on the outer wall of the rotating shaft 15. Subsequently, the airflow enters the interior of the airbag 2 through the air outlet on the outer wall of the rotating shaft 15, causing the airbag 2 to expand. The airbag 2 then compresses the liquid medicine around the rotating shaft 15, allowing the liquid medicine to be more concentrated on the inner wall of the tank 1, increasing the contact area between the liquid medicine and the first heating coil 17 and the second heating coil 18. By setting the airbag 2, the airbag 2 will expand under the action of airflow and push the liquid medicine in the central area of ​​the tank 1 to the edge, increasing the contact area between the liquid medicine and the first heating coil 17 and the second heating coil 18, and improving the heating effect of the device on the liquid medicine.

[0026] Please see Figure 5 As shown, the outer wall of the airbag 2 is fixed with multiple protrusions 3; the protrusions 3 are arc-shaped structures; by setting the protrusions 3, the airbag 2 can rotate together with the rotating shaft 15, and the protrusions 3 can increase the contact area between the outer wall of the airbag 2 and the liquid medicine, thereby improving the turbulence effect of the airbag 2 on the liquid medicine and improving the mixing effect of the liquid medicine.

[0027] Please see Figure 4 As shown, a baffle 4 is provided between the airbag 2 and each set of stirring blades 16; the baffle 4 and the rotating shaft 15 are fixedly connected; by providing the baffle 4, the baffle 4 can provide additional limiting effect on the airbag 2 when it expands, reduce the direct contact between the airbag 2 and the stirring blades 16, and thus reduce the damage to the airbag 2 caused by excessive contact with the stirring blades 16.

[0028] Please see Figure 5 As shown, the outer wall of the airbag 2 is fixed with a plurality of reinforcing ribs 5; the reinforcing ribs 5 are equidistantly arranged; by setting the reinforcing ribs 5, the structural strength of the outer wall of the airbag 2 can be improved, the airbag 2 can be improved in terms of resistance to fluid impact during operation, and thus the stability of the airbag 2 during operation can be improved.

[0029] Please see Figures 1 to 3As shown, the outer wall of the tank 1 is fixed with thermal insulation cotton 6; the thermal insulation cotton 6 and the first heating coil 17 and the second heating coil 18 are all through-connected; by setting thermal insulation cotton 6, due to its low thermal conductivity, the thermal insulation cotton 6 can reduce the heat exchange between the first heating coil 17 and the second heating coil 18 inside the tank 1 and the external environment when the heat is released, thereby reducing heat loss and improving the utilization rate of the heat energy of the first heating coil 17 and the second heating coil 18 by the device.

[0030] Working principle: By opening the valve at the inlet 12 and adding solid materials and solvent into the tank 1, the motor 14 drives the rotating shaft 15 to rotate. The rotating shaft 15 drives multiple sets of stirring blades 16 to rotate together and mix the materials in the tank 1. When it is necessary to remove the liquid from the tank 1, the valve at the outlet 13 can be opened. During the mixing and preparation process, the materials in the tank 1 need to be heated. Specifically, one end of the first heating coil 17 and the second heating coil 18 are connected to the medium supply equipment, and the heating medium is transported by the delivery pump, driving the heating medium to circulate in the first heating coil 17 and the second heating coil 18. During the process, the heating medium heats the materials in the tank 1 through heat conduction. After heating is completed, the liquid is removed from the tank. The medium can be discharged from the other end of the first heating coil 17 and the second heating coil 18 and reheated by the heating assembly. This cycle can then be repeated to circulate and heat the material inside the tank 1. The pressure relief valve 19 ensures stable air pressure inside the tank 1. The first heating coil 17 and the second heating coil 18 are two separate circulation systems. Therefore, during the preparation of the medicine, the medium supply in the second heating coil 18 can be greater than that in the first heating coil 17. That is, the first heating coil 17 is responsible for preheating the medicine, while the second heating coil 18 is responsible for the main heating, avoiding localized overheating inside the tank 1 and achieving differentiated heating of the medicine inside the tank 1. It is worth mentioning that the valves involved in the above-mentioned inlet 12, outlet 13, and pressure relief valve 19... The door structure is a mature existing technology, so it will not be described in detail here. During the preparation of the medicine liquid in the tank 1, the air inlet pipe 23 can be connected to the air pump, so that the airflow can enter the connecting pipe 22 through the air inlet pipe 23, and enter the interior of the rotating shaft 15 through the air inlet on the outer wall of the rotating shaft 15. Then the airflow can enter the interior of the airbag 2 through the air outlet on the outer wall of the rotating shaft 15, causing the airbag 2 to expand. The airbag 2 will then compress the medicine liquid around the rotating shaft 15, so that the medicine liquid can be more concentrated on the inner wall of the tank 1, increasing the contact area between the medicine liquid and the first heating coil 17 and the second heating coil 18. By setting the protrusion 3, the airbag 2 can rotate with the rotating shaft 15. The protrusion 3 can increase the contact area between the outer wall of the airbag 2 and the medicine liquid, thereby improving the turbulence of the medicine liquid by the airbag 2. The system functions to improve the mixing effect of the liquid medicine; by setting baffle 4, baffle 4 can provide additional limiting effect on the airbag 2 when it expands, reducing the direct contact between the airbag 2 and the stirring blade 16, thereby reducing the damage to the airbag 2 caused by excessive contact with the stirring blade 16; by setting reinforcing rib 5, reinforcing rib 5 can improve the structural strength of the outer wall of the airbag 2, improve the airbag 2's ability to resist fluid impact during operation, thereby improving the stability of the airbag 2 during operation; by setting heat insulation cotton 6, heat insulation cotton 6, due to its low thermal conductivity, can reduce the heat exchange between the first heating coil 17 and the second heating coil 18 in the tank 1 and the external environment when releasing heat, thereby reducing heat loss and improving the utilization rate of the heat energy of the first heating coil 17 and the second heating coil 18 of the device.
