Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine fermentation technology, specifically to a stirring device for fermenting traditional Chinese medicine preparations. Background Technology

[0002] Traditional Chinese medicine fermentation is a process in which extracts of Chinese herbs are added to simulate the intestinal environment by microorganisms. During the fermentation process, continuous stirring is required.

[0003] A search revealed that patent application number CN202222916785.X discloses a stirrer for fermenting traditional Chinese medicine. This stirrer can not only stir the traditional Chinese medicine and fermentation liquid in the fermentation tank by rotating the drum and stirring shell, but also heat the heat-conducting liquid by heating the drum and stirring shell with an electric heating tube, so that the temperature of fermentation can be increased while stirring. It is quite convenient to use.

[0004] However, the above-mentioned devices can only play the role of stirring and heating. Sometimes, the Chinese herbal extract added to the fermentation tank is not filtered sufficiently, and a small amount of Chinese herbal residue will be mixed into the fermentation tank. The Chinese herbal residue contains a variety of substances, including substances that were not extracted from the Chinese herbal extract. These substances may have little effect on the target disease or contain components that are detrimental to the target disease. Therefore, after being mixed into the extract, they can easily affect the efficacy of the Chinese herbal fermentation liquid. Therefore, there is a need for a device that can filter the Chinese herbal residue in a timely manner during the fermentation process to reduce the mixing of ineffective components from the Chinese herbal medicine into the fermentation liquid. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a stirring device for fermenting traditional Chinese medicine preparations, which solves the problem of difficulty in timely filtering of residues in traditional Chinese medicine extracts and preventing ineffective components from mixing in and affecting the efficacy of the fermentation liquid.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stirring device for fermentation of traditional Chinese medicine preparations, comprising a stirring tank, a horizontal plate fixedly connected to the bottom of the stirring tank, a plurality of support legs fixedly connected to the bottom of the horizontal plate, a stirring assembly installed inside the stirring tank, and a motor for driving the stirring assembly to rotate fixedly connected to the bottom of the horizontal plate.

[0007] The stirring assembly includes a rotating rod rotatably connected to the inner bottom of the stirring tank, multiple spiral plates fixedly connected to the outer side of the rotating rod, multiple filter plates slidably connected to the inner wall of the stirring tank, counterweight balls fixedly connected to both ends of the filter plates, multiple air supply pipes connected to the outer side of the stirring tank for blowing away the Chinese medicine residue on the surface of the filter plates, and multiple waste frames for collecting the Chinese medicine residue fixedly connected to the top end of the rotating rod.

[0008] Preferably, a heat-conducting plate is fixedly connected to the outer side of the mixing tank near the filter plate, a heating component is slidably connected to the outer side of the heat-conducting plate, a traction rope is fixedly connected between the heating component and the filter plate, and a crossbar for guiding the sliding direction of the traction rope is fixedly connected to the top of the mixing tank.

[0009] Preferably, the heating component includes a lifting plate slidably connected to a heat-conducting plate, a traction rope fixedly connected to the lifting plate, a sliding plate with a top opening slidably connected to the bottom of the lifting plate, a metal plate for generating heat through friction with the heat-conducting plate fixedly connected to the bottom of the sliding plate, and an elastic rope that movably passes through the sliding plate between the lifting plate and the horizontal plate.

[0010] Preferably, an annular sealing box is fixedly connected to the top of the horizontal plate, an air pump is fixedly connected to the top of the annular sealing box, the exhaust end of the air pump is connected to the annular sealing box, and one bottom end of the air supply pipe is connected to the annular sealing box.

[0011] Preferably, a base plate is fixedly connected to one bottom end of the rotating rod, and a plurality of pushing components for pushing the herbal extract upward at an angle are fixedly connected to the top of the base plate.

[0012] Preferably, the pushing assembly includes an inclined plate fixedly connected to the base plate, a swing plate rotatably connected to the top of the inclined plate, an opening at one end of the top of the inclined plate, a support plate fixedly connected to the bottom of the inclined plate, and a spring fixedly connected between the support plate and the swing plate.

[0013] Preferably, the bottom of the waste frame has a discharge port, a filter screen is installed on one side of the waste frame, and a bolt with one end extending into the interior of the waste frame is provided on one side of the filter screen.

[0014] Preferably, a flow guide plate with a notch is rotatably connected to one side of the waste frame, a force-bearing plate is fixedly connected to one end of the flow guide plate, and an elastic sheet is fixedly connected between the force-bearing plate and the waste frame.

[0015] Compared with the prior art, the present invention provides a stirring device for fermentation of traditional Chinese medicine preparations, which has the following beneficial effects:

[0016] 1. The continuous rotation of the spiral plate drives the filter plate to rise and fall continuously, thereby using the filter plate to continuously transport the residue in the herbal extract to the waste box. During the fermentation process of the herbal extract, the residue mixed in with the extract is removed, reducing the amount of ineffective or harmful components in the herbal medicine mixed into the fermentation liquid, thus affecting the efficacy of the fermentation liquid and ensuring the quality of the fermented herbal products.

[0029] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] Example 1

[0031] Figures 1-7 In one embodiment of the present invention, a stirring device for fermentation of traditional Chinese medicine preparations includes a stirring tank 1, a horizontal plate 2 fixedly connected to the bottom of the stirring tank 1, a plurality of support legs 3 fixedly connected to the bottom of the horizontal plate 2, a stirring assembly 4 installed inside the stirring tank 1, and a motor 5 for driving the stirring assembly 4 to rotate fixedly connected to the bottom of the horizontal plate 2. Traditional Chinese medicine extract and microorganisms are added to the stirring tank 1, and the motor 5 drives the stirring assembly 4 to stir the traditional Chinese medicine extract and microorganisms inside the stirring tank 1 evenly. The traditional Chinese medicine extract begins to ferment under the action of microorganisms, which can improve the uniformity of fermentation of traditional Chinese medicine extract.

[0032] The stirring assembly 4 includes a rotating rod 41 rotatably connected to the inner bottom of the stirring tank 1. Multiple spiral plates 42 are fixedly connected to the outer side of the rotating rod 41. Multiple filter plates 43 are slidably connected to the inner wall of the stirring tank 1. The filter plates 43 can only slide up and down along the inner wall of the stirring tank 1. Counterweight balls 44 are fixedly connected to both ends of each filter plate 43. Multiple air ducts 45 are connected to the outer side of the stirring tank 1 to blow away the medicinal residue on the surface of the filter plates 43. Multiple waste frames 46 for collecting the medicinal residue are fixedly connected to the top end of the rotating rod 41. As the motor 5 drives the rotating rod 41 to rotate, the spiral plate 42 rotates along with the rotating rod 41 until the bottom of the spiral plate 42 contacts the counterweight ball 44. The spiral plate 42 pushes the counterweight ball 44 upward until it passes under the counterweight ball 44 and moves onto the filter plate 43. The height of the spiral plate 42 as it passes the filter plate 43 gradually increases, thus pushing the filter plate 43 to rise continuously until it rises above the liquid surface of the herbal extract inside the mixing tank 1. During the process of the filter plate 43 rising... The herbal extract passes through the gaps in the filter plate 43, while the herbal residue in the extract remains on the surface of the filter plate 43. The air supply pipe 45, also located above the liquid surface, continuously blows air diagonally upwards from below the filter plate 43, accelerating the drying speed of the herbal residue on the surface of the filter plate 43 and simultaneously blowing the herbal residue into the air. As the rotating rod 41 rotates, the waste frame 46 collects the herbal residue that moves into the air. The herbal residue eventually adheres to the surface of the rotating waste frame 46 until the spiral plate 42 moves... After passing through the filter plate 43, the bottom of the filter plate 43 is no longer supported by the spiral plate 42 and falls downwards due to its own gravity. The continuous rotation of the spiral plate 42 drives the filter plate 43 to rise and fall continuously. In turn, the filter plate 43 continuously transports the residue in the Chinese herbal extract to the waste frame 46. During the fermentation process of the Chinese herbal extract, the residue mixed in with the extract is removed, reducing the amount of ineffective or harmful components in the Chinese herbal medicine mixed into the fermentation liquid, thus affecting the efficacy of the fermentation liquid and ensuring the quality of the fermented Chinese herbal medicine products.

[0033] A ring-shaped sealing box 10 is fixedly connected to the top of the horizontal plate 2. An air pump 11 is fixedly connected to the top of the ring-shaped sealing box 10. The exhaust end of the air pump 11 is connected to the ring-shaped sealing box 10. One end of the air supply pipe 45 is connected to the ring-shaped sealing box 10. The air pump 11 sends air into the ring-shaped sealing box 10 and then into the mixing tank 1 through the air supply pipe 45. The air blows obliquely upward from the bottom of the filter plate 43. On the one hand, it accelerates the evaporation rate of the herbal extract on the surface of the herbal residue, and reduces the penetration of ineffective and harmful components in the herbal residue into the herbal extract on its surface, and then drips into the mixing tank 1, causing ineffective and harmful components in the herbal medicine to mix into the herbal fermentation product. On the other hand, it blows the herbal residue into the air, so that the rotating waste frame 46 can collect the herbal residue floating in the air.

[0034] A base plate 12 is fixedly connected to one bottom end of the rotating rod 41. Multiple pushing assemblies 13 for pushing the herbal extract obliquely upwards are fixedly connected to the top of the base plate 12. Each pushing assembly 13 includes an inclined plate 131 fixedly connected to the base plate 12. A swing plate 132 is rotatably connected to the top of the inclined plate 131. One end of the inclined plate 131 is open. A support plate 133 is fixedly connected to the bottom of the inclined plate 131. A spring 134 is fixedly connected between the support plate 133 and the swing plate 132. During the rotation of the rotating rod 41 and the spiral plate 42, the base plate 131... Plate 12 rotates with the rotating rod 41, which in turn drives the inclined plate 131 and the swing plate 132 to rotate. The inclined plate 131 pushes the herbal extract at the bottom of the mixing tank 1 to move obliquely upward, thereby driving the herbal residue settled at the bottom of the mixing tank 1 to move upward. When the rotating rod 41 drives the spiral plate 42 to rotate slowly, the swing plate 132 experiences less resistance as the rotating rod 41 rotates slowly. The spring 134 pushes the swing plate 132 to rotate away from the inclined plate 131. The swing plate 132, which is tilted up from the inclined plate 131, blocks the herbal extract from flowing along... The surface of the inclined plate 131 slides over the surface, increasing its ability to move the herbal extract and increasing the force that pushes the herbal residue settled at the bottom of the mixing tank 1 upwards. The settled herbal residue, after being pushed up, can be screened by the filter plate 43 above the herbal extract. When the rotating rod 41 drives the spiral plate 42 to rotate rapidly, the inclined plate 131 and the swing plate 132 rotate at a relatively high speed with the rotating rod 41. The resistance of the herbal extract on the swing plate 132 increases, and the swing plate 132 is pushed, compressing and contracting the spring 134 downwards. Rotate until the swing plate 132 is in close contact with the upper surface of the inclined plate 131. At this time, the obstruction effect of the swing plate 132 on the herbal extract is reduced, which reduces the possibility of the swing plate 132 bending and deforming due to excessive resistance. The angle of the inclined plate 131 and the swing plate 132 can be automatically adjusted according to the stirring speed to ensure that the inclined plate 131 and the swing plate 132 push the herbal extract and the herbal residue at the bottom of the stirring tank 1 upward, reducing the possibility that the herbal residue cannot be separated from the herbal extract by the filter plate 43 due to settling at the bottom.

[0035] Example 2

[0036] Reference Figures 1-8Based on Embodiment 1, a heat-conducting plate 6 is fixedly connected to the outer side of the mixing tank 1 near the filter plate 43. A heating component 7 is slidably connected to the outer side of the heat-conducting plate 6. A traction rope 8 is fixedly connected between the heating component 7 and the filter plate 43. A horizontal column 9 for guiding the sliding direction of the traction rope 8 is fixedly connected to the top of the mixing tank 1. The heating component 7 includes a lifting plate 71 slidably connected to the heat-conducting plate 6. The traction rope 8 is fixedly connected to the lifting plate 71. A sliding plate 72 with a top opening is slidably connected to the bottom of the lifting plate 71. A metal plate 73 for generating heat through friction with the heat-conducting plate 6 is fixedly connected to the bottom of the sliding plate 72. An elastic rope 74 is provided between the lifting plate 71 and the horizontal plate 2, which movably passes through the sliding plate 72. When the filter plate 43 descends along the mixing tank 1, the filter plate 43 pulls the lifting plate 71 up through the traction rope 8, thereby pulling the sliding plate 72 and the metal plate 73 up. The elastic rope 74 is stretched and deformed by the lifting plate 71 until the spiral plate 42 pushes it. When the filter plate 43 rises, it no longer pulls the traction rope 8. The elastic rope 74 pulls the lifting plate 71 down under its own elastic force, which in turn drives the sliding plate 72 and the metal plate 73 down. During the rising and falling of the metal plate 73, the friction between the metal plate 73 and the heat-conducting plate 6 generates heat, which helps to heat up the mixing tank 1. When the heat generated by friction is insufficient, the electric heating device is used to heat the inside of the mixing tank 1. When the ambient temperature is high and heating is not required during the fermentation of Chinese herbal medicine, the sliding plate 72 is pulled to move away from the bottom of the lifting plate 71 and away from the mixing tank 1. After the metal plate 73 moves away from the mixing tank 1, it no longer contacts the heat-conducting plate 6. The filter plate 43 does not heat the mixing tank 1 when it rises and falls to filter the residue of Chinese herbal medicine inside the mixing tank 1. It can assist the heating of the mixing tank 1 by filtering the residue in the Chinese herbal medicine extract and stop heating as needed, reducing the power consumed when the mixing tank 1 is heated.

[0037] The bottom of the waste frame 46 has a discharge port, and a filter screen 14 is installed on one side of the waste frame 46. A bolt 15 is provided on one side of the filter screen 14, with one end extending into the interior of the waste frame 46. The Chinese medicine residue that enters the waste frame 46 sticks to the filter screen 14. When it is necessary to clean the Chinese medicine residue, the bolt 15 is removed from the waste frame 46, and then the filter screen 14 is moved to the outside of the mixing tank 1. The Chinese medicine residue on the surface of the filter screen 14 is rinsed. After rinsing, the filter screen 14 is reattached to one side of the waste frame 46 and the bolt 15 is used to fix the filter screen 14 to the waste frame 46, which reduces the difficulty of cleaning the Chinese medicine residue.

[0038] A notched guide plate 16 is rotatably connected to one side of the waste frame 46. A force-bearing plate 17 is fixedly connected to one end of the guide plate 16. An elastic sheet 18 is fixedly connected between the force-bearing plate 17 and the waste frame 46. When the rotation speed of the waste frame 46 with the rotating rod 41 is small, the air resistance on the force-bearing plate 17 is small. The elastic sheet 18 pushes the force-bearing plate 17 to rotate towards the opening of the waste frame 46, thereby driving the guide plate 16 closer to the waste frame 46 until the guide plate 16 is tightly attached to the waste frame 46. The Chinese medicine residue on the rotation path of the notch of the guide plate 16 can enter the waste frame 46 through the notch. When the rotating rod 41... When the rotation speed is too fast, the air resistance of the force plate 17 increases, pushing the elastic sheet 18 to bend and rotate away from the opening of the waste frame 46. The guide plate 16 is driven by the force plate 17 to have a certain angle with the waste frame 46. When the waste frame 46 rotates quickly with the rotating rod 41, the air on the surface flows to both sides along the inclined guide plate 16, reducing the air resistance of the waste frame 46. This can adjust the angle of the guide plate 16 when the stirring speed of the herbal extract is too fast, thereby reducing the air resistance of the waste frame 46 and reducing the possibility that the waste frame 46 will break off from the rotating rod 41 due to excessive pressure during rotation.
