Abstract
Description
Technical Field
[0001] This utility model belongs to the field of liniment preparation, specifically relating to a device for preparing external liniments. Background Technology
[0002] A liniment is a topical liquid preparation applied to the skin by rubbing or brushing. Liniments can also be applied to a soft cloth to cover the skin. Due to rubbing, some medicinal components in liniments can be absorbed through the skin, but liniments should not be used on broken skin.
[0003] Existing liniments have the following problems during preparation:
[0004] 1. The solid powder and liquid are not mixed sufficiently, resulting in clumping after mixing.
[0005] 2. Even after thorough mixing, drug residues will still remain. Existing methods for removing residues are cumbersome and inefficient.
[0006] 3. Heating the ointment to sterilize it affects its medicinal properties. Utility Model Content
[0007] The purpose of this invention is to provide a device for preparing topical liniments, which solves the above-mentioned problems through structural improvements.
[0008] To address the aforementioned problems in the existing technology, the technical solution adopted by this utility model is as follows:
[0009] An apparatus for preparing a topical liniment includes a mixing tank, a filtering tank, a sterilizing tank, and a collecting tank connected in sequence.
[0010] The mixing tank includes a tank body, which is connected to a feeding pipe and a water inlet pipe assembly. The mixing tank is also equipped with a spraying structure, a screening structure and a stirring structure.
[0011] The mixing tank is connected to the filter tank via a fourth water pipe, and the filter tank is connected to the sterilization tank via a fifth water pipe.
[0012] The sterilization tank is equipped with a filter membrane assembly inside, and the sterilization tank is connected to the collection tank through a sixth water pipe.
[0013] The entire preparation of the liniment can be completed by setting up a mixing tank, a filtering tank, a sterilization tank, and a collection tank.
[0014] Furthermore, the water inlet pipe assembly includes a first water pipe, a second water pipe, and a third water pipe. The first water pipe, the second water pipe, and the third water pipe are connected by a tee pipe. The third water pipe is connected to the mixing tank, the second water pipe is connected to the spray structure, the second water pipe is connected to a first water pump, and the first water pipe is connected to a first solenoid valve.
[0015] Furthermore, the spray structure includes a water distribution pipe connected to multiple nozzles, and the water distribution pipe is connected to a second water pipe via a spray pipe. The water distribution pipe includes an inner water distribution pipe and an outer water distribution pipe, both of which are connected to the spray pipe. By setting up the inner and outer water distribution pipes, the nozzles are more evenly distributed, resulting in more uniform liquid spraying and effectively washing away the powder on the screen.
[0016] Furthermore, the sieving structure includes a screen, the outer side of which is connected to the tube body via a connecting plate, and a support sleeve is provided in the middle of the screen. By setting up the screen, powder agglomeration can be avoided, resulting in more uniform mixing.
[0017] Furthermore, the stirring structure includes a rotating shaft rotatably connected to the tank body. From top to bottom, the rotating shaft is connected to a baffle plate, an upper stirring rod, and a lower stirring rod. The baffle plate is located on the upper side of the sieving structure and is detachably connected to the rotating shaft, with a clearance portion. A motor is connected to the top of the rotating shaft via a gear set, driving the rotating shaft to rotate. The upper stirring rod has a triangular cross-section and multiple water passage holes. The stirring structure has two functions: first, to stir the liquid and solid, ensuring thorough mixing; second, to disperse the raw material on the upper side of the screen by agitating it with the baffle plate, causing it to fall off the screen. A clearance portion is provided on the baffle plate to allow the support sleeve to pass through, and a very small gap exists between the lower side of the baffle plate and the screen, just enough for the raw material to pass through. A heater is installed inside the mixing tank. The heater raises the temperature, improving mixing efficiency and allowing the solid powder to mix with the liquid as quickly as possible.
[0018] Furthermore, the filter tank includes a fine filtration section and a coarse filtration section, with the coarse filtration section located at both ends of the fine filtration section. The coarse filtration section is equipped with a sponge, and the fine filtration section is equipped with one or more of activated carbon, quartz sand, and ceramic filter elements.
[0019] Furthermore, the filter membrane assembly includes a membrane body, with an upper connecting layer connected to the upper side and a lower connecting layer connected to the lower side. A water collection section is located in the middle of the membrane body, and the water collection section is connected to a water outlet pipe. The water outlet pipe is connected to a sixth water pipe. The filter membrane assembly is used for filtration and sterilization. To prevent high temperatures from affecting the efficacy of the medicine, using a filter membrane for sterilization ensures the effectiveness of the liniment. The membrane body is the core component for filtration and sterilization. The membrane body adopts a bent structure arrangement to increase the filtration area and improve filtration efficiency. One side of the membrane body is the inner side, and the other side is the outer side. Membrane filtration and sterilization involves sterilizing the filtered solution by moving it from one side of the membrane to the other.
[0020] The beneficial effects of this utility model are as follows:
[0021] 1. This utility model, by setting up a stirring structure, on the one hand, disperses solid powder to avoid clumping; on the other hand, it drives the stirring rod to stir the liquid, thereby improving the mixing efficiency.
[0022] 2. This utility model adopts membrane sterilization filtration and improves the structure of the membrane to improve filtration efficiency without affecting the efficacy of the medicine.
[0023] 3. This utility model adds a sieve to filter the powder and ensure the mixing quality. Attached Figure Description

[0039] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0040] Example 1:
[0041] like Figure 1 and 2As shown, an apparatus for preparing a topical liniment includes a mixing tank 1, a filtering tank 2, a sterilization tank 3, and a collection tank 4 connected in sequence.
[0042] The mixing tank 1 includes a tank body 14, which is connected to a feeding pipe 16 and a water inlet pipe assembly. The mixing tank 1 is also connected to a spray structure 12, a screening structure 13 and a stirring structure 11.
[0043] The mixing tank 1 is connected to the filter tank 2 via the fourth water pipe 74, and the filter tank 2 is connected to the sterilization tank 3 via the fifth water pipe 75.
[0044] The sterilization tank 3 is equipped with a filter membrane assembly 31 inside, and the sterilization tank 3 is connected to the collection tank 4 through the sixth water pipe 76.
[0045] The entire preparation of the liniment can be completed by setting up a mixing tank 1, a filtering tank 2, a sterilization tank 3, and a collection tank 4.
[0046] Example 2:
[0047] Based on Embodiment 1, the water inlet pipe assembly includes a first water pipe 71, a second water pipe 72, and a third water pipe 73. The first water pipe 71, the second water pipe 72, and the third water pipe 73 are connected by a T-connector. The third water pipe 73 is connected to the mixing tank 1, the second water pipe 72 is connected to the spray structure 12, the second water pipe 72 is connected to the first water pump 61, and the first water pipe 71 is connected to the first solenoid valve 51.
[0048] This application provides water supply to the spray structure 12 by setting up an inlet pipe assembly, and enables the spray structure 12 to circulate and spray, thereby improving the mixing effect.
[0049] When water is introduced, the first solenoid valve 51 is opened, and the first water pump 61 pumps the water into the spray structure 12, and then sprays it into the mixing tank 1 from the spray structure 12. Alternatively, without the first water pump 61, the first solenoid valve 51 is opened, and the liquid enters the mixing tank 1 from the third water pipe 73.
[0050] During mixing, the first solenoid valve 51 is closed and the first water pump 61 is started. The first water pump 61 draws the liquid from the bottom of the mixing tank 1 into the spray structure 12 and then sprays it out from the spray structure 12 to improve the mixing effect.
[0051] Example 3:
[0052] Based on Example 2, such as Figure 3 As shown, the spray structure 12 includes a water distribution pipe, which is connected to a plurality of spray nozzles 123. The water distribution pipe is connected to the second water pipe 72 through the spray pipe 124.
[0053] The water distribution pipe includes an inner water distribution pipe 121 and an outer water distribution pipe 122, both of which are connected to the spray pipe 124.
[0054] By setting up an inner water distribution pipe 121 and an outer water distribution pipe 122, the distribution of the nozzles 123 becomes more uniform, and the liquid spraying becomes more uniform, which can clean the powder on the screen 132.
[0055] Example 4:
[0056] Based on Example 3, such as Figure 4 As shown, the screening structure 13 includes a screen 132, the outer side of which is connected to the pipe body through a connecting plate 131, and a support sleeve 133 is provided in the middle of the screen 132.
[0057] By setting the sieve 132, powder clumping can be avoided, resulting in more uniform mixing.
[0058] When in use, the powder raw material is added through the feeding pipe 16. In order to prevent the powder from clumping, the added powder falls onto the screen 132 and is dispersed by the stirring structure 11. The dispersed powder falls from the screen 132 and mixes with the liquid below.
[0059] Example 5:
[0060] Based on Example 4, such as Figure 5 and 6 As shown, the stirring structure 11 includes a rotating shaft 111, which is rotatably connected to the tank body 14. The rotating shaft 111 is connected to a baffle plate 112, an upper stirring rod 113, and a lower stirring rod 114 from top to bottom. The baffle plate 112 is located on the upper side of the screening structure 13. The baffle plate 112 is detachably connected to the rotating shaft 111. The baffle plate 112 is provided with a clearance part 116.
[0061] The rotating shaft 111 is connected to a motor via a gear set above it, and the rotating shaft 111 is driven to rotate by the motor.
[0062] The upper stirring rod 113 has a triangular cross-section and is provided with multiple water passage holes 115.
[0063] The stirring structure 11 has two functions: first, to stir the liquid and solid to ensure that they are fully mixed; second, to disperse the raw material on the upper side of the screen 132 by using the deflector 112 to make the raw material fall off the screen 132.
[0064] An abutment 116 is provided on the deflector plate 112 to avoid the support sleeve 133. There is a very small gap between the lower side of the deflector plate 112 and the screen 132, which is just enough to allow the raw material to pass through.
[0065] The mixing tank 1 is equipped with a heater 15.
[0066] A heater 15 is installed inside the mixing tank 1 to increase the temperature and improve the mixing efficiency, so that the solid powder can be mixed with the liquid as quickly as possible.
[0067] Example 6:
[0068] Based on Example 7, such as Figure 7 As shown, the filter tank 2 includes a fine filtration section 21 and a coarse filtration section 22, with the coarse filtration section 22 located at both ends of the fine filtration section 21.
[0069] The coarse filtration section 22 is equipped with a sponge, and the fine filtration section 21 is equipped with one or more of activated carbon, quartz sand, and ceramic filter elements.
[0070] Example 7:
[0071] Based on Example 6, such as Figure 8-10 As shown, the filter membrane assembly 31 includes a membrane body 311, an upper connecting layer 32 is connected to the upper side of the membrane body 311, a lower connecting layer 33 is connected to the lower side of the membrane body 311, a water collection part 35 is provided in the middle of the membrane body 311, and a water outlet pipe 34 is connected to the water collection part 35.
[0072] The water outlet pipe 34 is connected to the sixth water pipe 76.
[0073] The filter membrane assembly 31 is used for filtration and sterilization. In order to prevent high temperature from affecting the efficacy of the medicine, using a filter membrane for sterilization can ensure the effect of the liniment.
[0074] The membrane body 311 is the core component for filtration and sterilization. The membrane body 311 adopts a bent structure to increase the filtration area and improve filtration efficiency. One side of the membrane body 311 is the inner side, and the other side is the outer side. Membrane filtration and sterilization is achieved by passing the filtered solution from one side of the membrane to the other.
[0075] During operation, the liquid enters the sterilization tank 3 located on the outer side 313 of the membrane, passes through the membrane body 311, and enters the inner side 312 of the membrane. The inner side 312 of the membrane is the water collection part 35. The sterilized liquid enters the collection tank 4 through the sixth water pipe 76 for collection.
[0076] Specific working principle:
[0077] First, open the first solenoid valve 51 to inject liquid into the mixing tank 1. Then, add solid powder into the mixing tank 1 through the feeding pipe 16 (the solid powder falls onto the screen 132). Close the first solenoid valve 51, start the motor and the first water pump 61. The motor drives the stirring structure 11 to rotate. The deflector 112 moves the solid powder on the screen 132, breaking the powder into the lower side of the mixing tank 1. At the same time, the spray structure 12 sprays liquid from the nozzle 123 to wash the screen 132 and the deflector 112, washing the powder off the screen 132 and the deflector 112. Turn on the heater 15 to heat the mixing process. Through heating and stirring, the mixing efficiency is improved.
[0078] After mixing, open the second solenoid valve 52 and the second water pump 62. The mixed liquid is filtered through the filter tank 2 and then injected into the sterilization tank 3.
[0079] The vacuum pump 63 is turned on for sterilization filtration. The liquid entering the sterilization tank 3 is initially located on the outer side of the membrane 313. As a pressure difference is generated between the inner side of the membrane 312 and the outer side of the membrane 313, the liquid passes through the membrane body 311 and enters the inner side of the membrane 312. Then, it enters the collection tank 4 through the sixth water pipe 76 for collection.
[0080] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
