Description

Technical Field

[0001] This utility model relates to the field of ointment production technology, specifically to a heating and mixing device for ointment production. Background Technology

[0002] Ointments are semi-solid topical preparations with a certain consistency, made by uniformly mixing drugs with a suitable base. Common bases are classified into oil-based, water-soluble, and emulsion-based bases. Among them, ointments made with emulsion bases that are easy to apply are called creams. Due to the different dispersion states of drugs in the base, there are solution-type ointments and suspension-type ointments.

[0003] Traditional ointment production heating and mixing equipment usually uses a single heating method, such as setting a heating jacket only on the outside of the tank. This method cannot ensure that the ointment is heated evenly in all parts of the tank, which can easily lead to local overheating or underheating. Taking the production of ointments containing heat-sensitive ingredients as an example, local overheating may cause the heat-sensitive ingredients to become ineffective, affecting the quality stability of the ointment. In addition, most existing equipment has a simple stirring structure and unreasonable stirring blade shape and layout, which cannot fully mix the multiple components of the ointment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heating and mixing device for ointment production, which solves the problems of using a single heating method in ointment production heating and mixing devices, which easily leads to local overheating or insufficient heating, and the simple stirring structure, which cannot fully mix the multiple components of the ointment.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a heating and mixing device for ointment production, comprising a tank body, support plates fixedly connected to the left and right sides of the tank body, a feed inlet fixedly connected to one side wall of the tank body, a discharge outlet fixedly connected to one side wall of the tank body, a sealing cover movably connected to the upper surface of the tank body, a fixing ring fixedly connected to both the sealing cover and one side wall of the tank body, a fixing bolt connected to the internal thread of the fixing ring, and an electromagnetic induction heating wire fixedly connected inside the tank body.

[0006] Preferably, a heater is fixedly connected to the upper surface of the sealing cap, a drive motor is fixedly connected to the upper surface of the heater, an air pump is fixedly connected to one side wall of the tank, a circulation pipe is fixedly connected to one side wall of the air pump, and the circulation pipe is connected to both the heater and the tank.

[0007] Preferably, a temperature sensor is fixedly connected to the inner wall of the tank, a rotating shaft is rotatably connected inside the tank and the rotating shaft is connected to a drive motor, and a pair of first connecting rings are rotatably connected to the outer wall of the rotating shaft.

[0008] Preferably, a fixing rod is fixedly connected to one side wall of the first connecting ring, a rotating shaft is rotatably connected inside the fixing rod, a limit ring is fixedly connected to the upper surface of the rotating shaft, a scraper is fixedly connected to the lower surface of the rotating shaft, and a torque sensor is fixedly connected to one side wall of the fixing rod.

[0009] Preferably, the outer wall of the rotating shaft is rotatably connected with a plurality of second connecting rings, and protrusions are fixedly connected to the left and right sides of the second connecting rings. A connecting rod is fixedly connected to one side wall of the protrusion, and a stirring blade is fixedly connected to one side wall of the connecting rod.

[0010] Beneficial effects

[0011] This invention provides a heating and mixing device for ointment production. Compared with the prior art, it has the following advantages:

[0012] (1) The electromagnetic induction heating wire fixed inside the tank can directly heat the ointment inside the tank, raising the temperature of the ointment from the inside. At the same time, the heater on the upper surface of the sealing cap is connected to the tank through the circulation pipe to realize circulating heating. The temperature sensor fixed to the inner wall of the tank monitors the temperature of the ointment inside the tank in real time and feeds the temperature data back to the control system. The control system adjusts the power of the heater and the working state of the electromagnetic induction heating wire precisely according to the preset temperature value. During the heating stage of the ointment, the heating power can be increased to raise the temperature quickly; when it approaches the target temperature, the power is automatically reduced to achieve precise temperature control.

[0013] (2) The drive motor drives the rotating shaft to rotate, and the multiple second connecting rings connected to the outer wall of the rotating shaft rotate accordingly. The stirring blades connected to the second connecting rings through the protrusions and connecting rods form a multi-directional stirring flow field in the tank. During the rotation, stirring forces in different directions are generated, so that the paste can be fully rolled and mixed in the tank. At the same time, the scraper fixed to the rotating shaft on the fixed rod connected to the first connecting ring is close to the inner wall of the tank. When the rotating shaft rotates, the scraper can not only scrape off the paste attached to the inner wall of the tank, but also assist in stirring, prevent the paste from accumulating on the tank wall, and further improve the mixing effect. The rotating shaft of the scraper can rotate in the fixed rod, and can automatically adjust the scraping angle according to the shape of the inner wall of the tank and the paste adhesion, ensuring a good scraping effect. The air pump can extract and circulate the gas in the tank through the circulation pipe. Attached Figure Description

[0018] 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.

[0019] Example 1:

[0020] Please see Figure 1-3 As shown in the figure, this embodiment proposes a heating and mixing device for ointment production, including a tank 1. Support plates 2 are fixed to the left and right sides of the tank 1. A feed inlet 3 is fixed to one side wall of the tank 1, and a discharge outlet 4 is fixed to one side wall of the tank 1. A sealing cover 5 is movably connected to the upper surface of the tank 1. A fixing ring 6 is fixed to both the sealing cover 5 and one side wall of the tank 1. A fixing bolt 7 is threaded inside the fixing ring 6. An electromagnetic induction heating wire 24 is fixed inside the tank 1. The support plates 2 fixed to the left and right sides of the tank 1 provide a stable support foundation for the entire device. The feed inlet 3 and discharge outlet 4 fixed to one side wall of the tank 1 respectively undertake the important tasks of inputting ointment raw materials and outputting finished products. The sealing cover 5 movably connected to the upper surface of the tank 1 is tightly connected to one side wall of the tank 1 through the fixing ring 6 and the fixing bolt 7. Moreover, the electromagnetic induction heating wire 24 raises the temperature of the ointment from the inside, resulting in faster heating and effectively avoiding the problem of uneven heating of the ointment inside due to overheating of the outer wall of the tank 1.

[0021] Preferably, a heater 8 is fixedly attached to the upper surface of the sealing cap 5, and a drive motor 9 is fixedly attached to the upper surface of the heater 8. A vacuum pump 10 is fixedly attached to one side wall of the tank body 1, and a circulation pipe 11 is fixedly attached to one side wall of the vacuum pump 10. The circulation pipe 11 is connected to both the heater 8 and the tank body 1. The heater 8 fixedly attached to the upper surface of the sealing cap 5 is connected to the tank body 1 through the circulation pipe 11, forming a highly efficient circulating heating system. When the heater 8 is working, the heat generated is transferred to the tank body 1 through the circulation pipe 11. It works in conjunction with the electromagnetic induction heating wire 24 fixedly attached to the tank body 1 to comprehensively improve the heating effect of the ointment in the tank. The output shaft of the drive motor 9 fixedly attached to the upper surface of the heater 8 is connected to the rotating shaft 13 inside the tank body 1. When the drive motor 9 is running, it drives the rotating shaft 13 to rotate, thereby driving the stirring blade 23 and the scraper 18 to work, ensuring stable operation of the stirring and scraper 18 and improving the mixing efficiency.

[0022] Preferably, a temperature sensor 12 is fixedly connected to the inner wall of the tank 1, and a rotating shaft 13 is rotatably connected inside the tank 1. The rotating shaft 13 is connected to the drive motor 9. A pair of first connecting rings 14 are rotatably connected to the outer wall of the rotating shaft 13. The rotating shaft 13 plays a core role in power transmission in the equipment. The power generated by the operation of the drive motor 9 is efficiently transmitted to the stirring and scraping components inside the equipment through the connection with the rotating shaft 13. When the drive motor 9 starts, it drives the rotating shaft 13 to rotate, thereby driving the second connecting ring 20, the first connecting ring 14, and the stirring blade 23 and scraper 18 installed on the outer wall of the rotating shaft 13 to work, realizing the stirring and scraping operation of the paste in the tank 1, ensuring that the paste can be fully mixed during the heating process and improving production efficiency.

[0023] Preferably, a fixing rod 15 is fixedly connected to one side wall of the first connecting ring 14. A rotating shaft 16 is rotatably connected inside the fixing rod 15. A limit ring 17 is fixedly connected to the upper surface of the rotating shaft 16, and a scraper 18 is fixedly connected to the lower surface of the rotating shaft 16. A torque sensor 19 is fixedly connected to one side wall of the fixing rod 15. The fixing rod 15 fixed to one side wall of the first connecting ring 14 provides a stable foundation for the installation and operation of the scraper 18. Due to its strong rigidity, the fixing rod 15 can reliably connect the scraper 18 to the first connecting ring 14. When the rotating shaft 13 rotates at high speed and drives the first connecting ring 14 to operate, it effectively prevents the scraper 18 from shaking or falling off. The rotating shaft 16 connected inside the fixing rod 15 gives the scraper 18 flexible self-adaptive ability. When the scraper 18 moves on the inner wall of the tank 1, it will push the ointment near the tank wall, so that this part of the ointment forms convection with the ointment in the central area of ​​the tank. For ointments containing multiple ingredients with large differences in proportion, this convection can promote more thorough mixing of the ingredients and significantly improve the mixing effect.

[0024] Preferably, a plurality of second connecting rings 20 are rotatably connected to the outer wall of the rotating shaft 13. Protrusions 21 are fixed to the left and right sides of the second connecting rings 20. A connecting rod 22 is fixed to one side wall of the protrusions 21. A stirring blade 23 is fixed to one side wall of the connecting rod 22. When the rotating shaft 13 is driven by the drive motor 9, the plurality of second connecting rings 20 rotatably connected to the outer wall of the rotating shaft 13 rotate synchronously. The protrusions 21 fixed to the left and right sides of the second connecting rings 20 are connected to the stirring blades 23 through the connecting rods 22, so as to efficiently transmit the rotational power of the rotating shaft 13 to the stirring blades 23. Multiple stirring blades 23 operate simultaneously in different positions, forming a complex and multi-directional stirring flow field in the tank 1, which can cover all areas inside the tank 1 and avoid the occurrence of stirring dead zones.

[0025] In use, all raw materials required for ointment production, whether liquid, paste, or powder, enter the equipment through the feed inlet 3 fixed to one side wall of the tank 1. The diameter and position of the feed inlet 3 are carefully designed to adapt to different types of raw material conveying pipelines, ensuring smooth entry of raw materials into the tank 1. The electromagnetic induction heating wire 24 fixed inside the tank 1 directly heats the ointment inside the tank 1 using the principle of electromagnetic induction. When the heater 8 is working, the heat generated is transferred to the tank 1 through the circulation pipe 11, working in conjunction with the electromagnetic induction heating wire 24 to comprehensively improve the heating effect of the ointment inside the tank. The drive motor 9 on the sealing cover 5 starts, driving the connected rotating shaft 13 to rotate inside the tank 1. A pair of first connecting rings 14 and several second connecting rings 20 rotatably connected to the outer wall of the rotating shaft 13 rotate synchronously. The protrusions 21 fixed on the left and right sides of the second connecting rings 20 efficiently transmit the rotational power of the rotating shaft 13 to the stirring blades 23 through the connecting rods 22, so that multiple stirring blades 23 operate at different positions at the same time, forming a complex and multi-directional stirring flow field in the tank 1, covering all areas inside the tank 1, avoiding stirring dead corners, and greatly improving stirring efficiency. When the rotating shaft 13 rotates, the scraper 18 moves close to the inner wall of the tank 1 to scrape off the paste adhering to the tank wall, assisting in stirring and preventing the paste from accumulating on the tank wall. After the paste completes the heating and mixing process in the tank 1, it is discharged through the discharge port 4 fixed on the other side of the tank 1.
