Description

Technical Field

[0001] This application relates to the technical field of traditional Chinese medicine decocting, and particularly to a multi-station traditional Chinese medicine decocting device. Background Art

[0002] With the development of medical technology and the increasing demand for the use of traditional Chinese medicine, traditional Chinese medicine decocting devices have gradually changed from traditional manual single-pot decocting to multi-station automatic decocting equipment, which can effectively improve the efficiency of traditional Chinese medicine decocting and meet clinical and market demands. Therefore, multi-station traditional Chinese medicine decocting devices have broad application prospects in the current field of traditional Chinese medicine decocting.

[0003] In the prior art, most multi-station traditional Chinese medicine decocting devices adopt an independent heating mode for each station. In this decocting mode, each station needs to be equipped with a separate heating element, and the heating units of each station do not assist each other. Although the operation is relatively simple, there are obvious unreasonable points in the heat energy utilization route. The independent heating mode means that the heating processes of each station are independent of each other, and the heat only acts on the medicine pot of this station, and the effective transfer and comprehensive utilization of heat between different stations cannot be realized. In actual operation, this heat energy utilization method leads to a great waste of energy consumption. When multiple stations work simultaneously, a large amount of heat is consumed within each station. For example, when a certain station is in a stage where a large amount of heating is not required, it cannot utilize the excess heat generated by other stations for auxiliary heating. The unreasonable utilization of heat energy results in high energy consumption during the operation of the overall equipment, which not only increases the cost of traditional Chinese medicine decocting but also does not meet the requirements of the era of energy conservation and emission reduction.

[0004] Therefore, a multi-station traditional Chinese medicine decocting device is proposed to solve some problems existing in the above prior art. Summary of the Invention

[0008] Furthermore, a material bucket is installed in the medicine pot, and evenly distributed filter holes are provided at the bottom of the material bucket. Ceramic layers are attached to the inner wall of the medicine pot and the outer surface of the material bucket.

The magnets evenly distributed on the first coupling disc are magnetically attracted to the magnets evenly distributed on the second coupling disc.

[0011] Furthermore, a concave cavity that is recessed upward is provided at the bottom of the material bucket, and the internal size of the concave cavity is adapted to the outer size of the stirring blade.

[0012] Furthermore, a one-way valve is installed in the air supply pipe, and a one-way valve is also installed in the return pipe.

[0013] Furthermore, a toothed ring is circumferentially provided on the cylindrical surface of the collar, and a first gear meshes with the outer side of the toothed ring. A servo motor is fixed inside the base.

[0015] Compared with the prior art, the advantages of the present application are as follows:

[0016] 1. This application is provided with multiple medicine pots, enabling the simultaneous decocting operations of multiple traditional Chinese medicines. The decocting operation of traditional Chinese medicines is carried out by means of heating with hot steam. A number of medicine pots are enabled in sequence. Through the connection of the shunt round box and the return pipe, the hot steam flowing through the side wall cavity of the later-enabled medicine pot can be diverted to the side wall cavity of the previously-enabled medicine pot, achieving an optimal distribution of the hot steam discharged from each air outlet pipe. This can optimize the recycling mode of the discharged hot steam, help reduce the energy loss during the multi-station decocting of traditional Chinese medicines by this device, facilitate energy-saving processing. At the same time, through the rotation control of the collar, the second round hole can be manipulated to dock with different return pipes, flexibly adjusting the flow direction of the recycled hot steam discharged from the air outlet pipe according to actual needs, which is conducive to enhancing the flexibility during the actual use of this device.

[0017] 2. By fixedly installing the guide plate in the side wall cavity of the medicine pot, two spiral and overlapping steam flow channels, namely the first flow channel and the second flow channel, can be formed in the side wall cavity of the medicine pot. When the hot steam flows in the side wall cavity of the medicine pot, it can present a spiral and overlapping posture, enabling the hot steam to be evenly dispersed in the side wall cavity of the medicine pot, performing a more stable and uniform heating operation on the traditional Chinese medicine being decocted inside the medicine pot, avoiding uneven local heating during the decocting process of traditional Chinese medicine and affecting the decocting effect, which is conducive to enhancing the stability of this device when decocting traditional Chinese medicines.

[0018] 3. By installing the stirring blades inside the medicine pot and arranging the eddy current chamber and the vortex fan installed therein in the bottom cavity of the medicine pot, and cooperating with the magnetic attraction of the magnets in the first coupling disk and the second coupling disk, when the hot steam flows through the bottom cavity of the medicine pot, it will drive the vortex fan to rotate. Through the transmission of the first coupling disk and the second coupling disk, the stirring blades are driven to rotate inside the medicine pot, which can stir the liquid medicine in the medicine pot during the decocting process of traditional Chinese medicine, facilitating the improvement of the uniformity during the decocting of traditional Chinese medicines. At the same time, by utilizing the flow of the hot steam to drive the rotation of the stirring blades, there is no need to use other additional electric drive units, which helps reduce the energy consumption during the operation of this device and facilitates further energy-saving and environmental protection processing operations.

[0019] 4. By stacking a number of shunt round boxes vertically and arranging the first gears correspondingly set on the outside of each shunt round box on the same vertical line, the up-and-down movement of the sliding end of the battery slide rail can be used to manipulate the second gear to engage with different first gears, enabling this device to realize the rotation control of multiple collars by using only a single servo motor. While ensuring the precise and stable rotation control of multiple collars, the usage amount of servo motors can be effectively reduced, and the manufacturing and usage costs of this device can be effectively reduced.

[0032] In the embodiments, the technical solutions of the present application will be clearly and completely described in conjunction with the accompanying drawings of the specification. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the protection scope of the present application.

[0033] Example 1:

[0034] The present invention provides a multi-station Chinese medicine decocting device. Please refer to Figure 1 - Figure 10 , which includes a base 1. A plurality of medicine pots 2 are fixedly installed on the top of the base 1, and the tops of the medicine pots 2 are covered with pot lids 201. Symmetrically arranged air inlet pipes 203 and air outlet pipes 204 are fixed on the outer end walls of the medicine pots 2, and both the air inlet pipes 203 and the air outlet pipes 204 communicate with the side wall cavities of the medicine pots 2. The air inlet pipes 203 are externally connected to an air supply pipe 205. The outer end of each air outlet pipe 204 is connected to a flow distribution round box 5 fixed in the base 1, and a first round hole 501 with the same number as the medicine pots 2 is opened on the cylindrical surface of the flow distribution round box 5. A collar 502 is rotatably sleeved on the outside of the flow distribution round box 5, and a second round hole 503 is opened on the collar 502. A first outer shell 504 fixed in the base 1 is rotatably sleeved on the outside of the collar 502, and a plurality of return pipes 505 with the same number as the medicine pots 2 are fixedly arranged around the first outer shell 504. The plurality of return pipes 505 are in one-to-one correspondence and communication with the plurality of air inlet pipes 203. The plurality of medicine pots 2 are enabled in sequence according to their arrangement positions. An exhaust pipe 506 is fixedly connected to the bottom of the flow distribution round box 5 corresponding to the first enabled medicine pot 2.

[0035] During the use of the device, the staff can use the device to perform the decocting operations of multiple Chinese medicines. Each medicine pot 2 is a work station, and each medicine pot 2 can perform the decocting operation of Chinese medicines. The plurality of medicine pots 2 can perform the decocting and processing of the same Chinese medicine or the decocting and processing of different Chinese medicines. When the device is used, according to the positions of the medicine pots 2, the plurality of medicine pots 2 are enabled one by one. The air supply pipe 205 is externally connected to a hot steam supply device. Through the connection of the air supply pipe 205 and the corresponding air inlet pipe 203, hot steam is transported into the side wall cavity of the medicine pot 2, and then is discharged through the air outlet pipe 204. During the flow of the hot steam in the side wall cavity of the medicine pot 2, heat is transferred to the inside of the medicine pot 2, realizing the heating operation for decocting the Chinese medicine in the medicine pot 2. Since the hot steam releases heat in the medicine pot 2, the temperature of the hot steam discharged through the air outlet pipe 204 decreases. The temperature of the hot steam at the air outlet pipe 204 associated with each medicine pot 2 is lower than the temperature of the hot steam at the air inlet pipe 203.

[0036] Since traditional Chinese medicine decoction is generally carried out by boiling vigorously over high heat for a short time, simmering over medium heat, and stewing slowly over low heat, the heat requirement during the traditional Chinese medicine decoction process gradually decreases. Due to the time difference in the start-up time of multiple medicine pots 2 during the use of this device, the state of decocting traditional Chinese medicine in adjacent two medicine pots 2 is inconsistent. The temperature of the traditional Chinese medicine being decocted in the later-started medicine pot 2 is higher than that in the previous medicine pot 2. For example, when the traditional Chinese medicine is being decocted in the later medicine pot 2 over high heat vigorously, the traditional Chinese medicine in the previous medicine pot 2 has already entered the state of simmering over medium heat. This makes the temperature difference between the hot steam discharged from the air outlet pipe 204 associated with the later medicine pot 2 and the temperature required for the previous medicine pot 2 relatively small. Therefore, by rotating the collar 502, the corresponding first round hole 501, second round hole 503, and the return pipe 505 are driven to communicate, so that the hot steam discharged from the air outlet pipe 204 corresponding to the later-started medicine pot 2 will enter the air inlet pipe 203 corresponding to the previous medicine pot 2. The hot steam discharged from the later medicine pot 2 is introduced into the previous medicine pot 2 and used in combination with the hot steam supplied by the air supply pipe 205. The optimal distribution of the hot steam discharged from the air outlet pipe 204 can optimize the utilization of heat energy, which is beneficial to reducing the energy loss during the multi-station decoction of traditional Chinese medicine by this device and facilitating the realization of energy-saving processing.

[0037] Temperature sensors are installed in the air inlet pipe 203, air outlet pipe 204, and return pipe 505 to detect the real-time temperature of the hot steam at the corresponding positions, which is convenient for ensuring the control stability of the recycling of hot steam. An electric control valve is installed in the return pipe 505, which can control the efficiency of the hot steam flowing back into the side wall cavity of the previous medicine pot 2, facilitating the adjustment of the optimal heating temperature in cooperation with the air supply pipe 205. A one-way valve is installed in the air supply pipe 205, and a one-way valve is also installed in the return pipe 505, so that the steam can flow stably in this device. The one-way valve installed in the air supply pipe 205 can prevent the return steam in the return pipe 505 from entering the external hot steam supply device through the air supply pipe 205. The multiple return pipes 505 connecting different shunt round boxes 5 to the same air inlet pipe 203 are set as the same group. The one-way valves installed in the return pipes 505 can prevent the hot steam in the same group of return pipes 505 from interfering with each other when supplying hot steam to the air inlet pipe 203, effectively ensuring the stability during the operation of this device.

[0038] Please refer to Figure 1 and Figure 2, A number of medicine pots 2 are distributed around the top of the base 1. A groove 101 is provided on the base 1 between two adjacent medicine pots 2. The outer side of the medicine pot 2 is wrapped with a heat preservation sleeve 202. By distributing a number of medicine pots 2 around the top of the base 1, the overall device becomes more compact, which is beneficial to the economical use of the space in the processing workshop. At the same time, the more compactly arranged multiple medicine pots 2 are convenient for personnel to add traditional Chinese medicine. By providing the inwardly recessed groove 101 between two adjacent medicine pots 2 on the outer side of the base 1, it can provide more standing space for the staff. With mutual cooperation, the operation convenience during the actual use of the device can be effectively improved. By wrapping the heat preservation sleeve 202 around the outer side of the medicine pot 2, the loss of heat dissipated outward due to the flow of hot steam in the side wall cavity of the medicine pot 2 can be reduced, ensuring the stability of the heat supply of the hot steam to the medicine pot 2.

[0039] Please refer to Figure 3 and Figure 8 , A deflector 206 arranged in a spiral structure is fixed in the side wall cavity of the medicine pot 2. The side wall cavity of the medicine pot 2 is divided by the deflector 206 into a first flow channel 207 communicating with the intake pipe 203 and a second flow channel 208 communicating with the outlet pipe 204. The bottom cavity of the medicine pot 2 is communicated between the first flow channel 207 and the second flow channel 208. When the device is in use, since the deflector 206 arranged in a spiral structure is fixed in the side wall cavity of the medicine pot 2, the side wall cavity of the medicine pot 2 can be divided into two independent and spirally intertwined steam flow channels by means of the deflector 206. During the process of heating the inside of the medicine pot 2 with steam, the hot steam enters the side wall cavity of the medicine pot 2 through the intake pipe 203 and flows in a spiral posture along the first flow channel 207, then enters the bottom cavity of the medicine pot 2, and then flows in a spiral posture along the second flow channel 208, and finally is discharged through the outlet pipe 204. By heating the medicine pot 2 from the bottom and side walls with hot steam, since the first flow channel 207 and the second flow channel 208 are intertwined with each other, the hot steam can be evenly dispersed in the side wall cavity of the medicine pot 2, and a more stable and uniform heating operation can be carried out for the traditional Chinese medicine boiling inside the medicine pot 2, avoiding uneven local heating during the traditional Chinese medicine boiling process and affecting the boiling effect, and effectively improving the stability of the device when boiling traditional Chinese medicine.

[0040] Please refer to Figure 3 and Figure 7, a material bucket 3 is installed inside the medicine pot 2, and evenly distributed filter holes are opened at the bottom of the material bucket 3. Ceramic layers are attached to the inner wall of the medicine pot 2 and the outer surface of the material bucket 3. During the use of this device, by installing the material bucket 3 inside the medicine pot 2 and opening evenly distributed filter holes at the bottom of the material bucket 3, when the staff is boiling traditional Chinese medicine, the traditional Chinese medicine raw materials can be put into the material bucket 3. After the traditional Chinese medicine is boiled, the staff only needs to lift and remove the material bucket 3 to conveniently clean the residues of the traditional Chinese medicine raw materials, which is beneficial to improving the convenience of the staff using this device to boil traditional Chinese medicine. At the same time, by attaching the ceramic layer to the inner wall of the medicine pot 2 and the outer surface of the material bucket 3, the wear resistance, scratch resistance, and easy cleaning characteristics of the inner wall of the medicine pot 2 and the outer surface of the material bucket 3 can be enhanced, which can not only ensure the stability during the boiling of traditional Chinese medicine but also effectively improve the stability and service life of this device during use.

[0041] Please refer to Figure 3 , Figure 5 and Figure 8 , a stirring blade 4 is rotatably installed inside the medicine pot 2 below the material bucket 3. An eddy current chamber 401 connected between the first flow channel 207 and the second flow channel 208 is arranged in the bottom cavity of the medicine pot 2, and a vortex fan 402 is rotatably installed in the eddy current chamber 401. The vortex fan 402 is drivingly connected to the stirring blade 4. A first coupling disk 403 fixedly connected to the central axis of the vortex fan 402 is rotatably installed in the bottom cavity of the medicine pot 2. A second coupling disk 404 fixedly connected to the central axis of the stirring blade 4 is rotatably installed inside the medicine pot 2. The magnets evenly distributed on the first coupling disk 403 are magnetically attracted to the magnets evenly distributed on the second coupling disk 404. When this device is in use, when the hot steam flows from the first flow channel 207 into the second flow channel 208, it will pass through the eddy current chamber 401 arranged in the bottom cavity of the medicine pot 2. Through the driving force generated by the flow of the hot steam, the vortex fan 402 is driven to drive the first coupling disk 403 to rotate. Then, by virtue of the magnetic attraction between the magnets on the first coupling disk 403 and the second coupling disk 404, the second coupling disk 404 rotates synchronously with the first coupling disk 403, driving the stirring blade 4 to rotate inside the medicine pot 2. During the boiling of traditional Chinese medicine, the liquid medicine in the medicine pot 2 is stirred, which can effectively improve the uniformity during the boiling of traditional Chinese medicine, is beneficial to improving the boiling effect of traditional Chinese medicine, and realizes the rotation drive of the stirring blade 4 by means of the flow of hot steam without using other additional electric drive units, which is beneficial to reducing the energy consumption during the operation of this device and facilitating the further realization of energy-saving and environmental protection processing operations.

[0042] The inner wall of the medicine pot 2 is made of non-magnetic material, which will not interfere with the magnetic attraction of the magnets between the first coupling disk 403 and the second coupling disk 404. During the process of transmitting the rotational power to the stirring blade 4, the magnets on the first coupling disk 403 are magnetically attracted to the magnets on the second coupling disk 404. The magnets are evenly distributed around the first coupling disk 403 and the second coupling disk 404. On the first coupling disk 403 or the second coupling disk 404, the magnetic poles of two adjacent magnets face in opposite directions. For example, if the magnetic poles of the magnets on the top of the first coupling disk 403 are arranged in the states of positive, negative, and positive, then the magnetic poles of the magnets on the bottom of the second coupling disk 404 are arranged in the states of negative, positive, and negative. This makes it difficult for the first coupling disk 403 and the second coupling disk 404 to rotate relative to each other radially when connecting the rotational power between the first coupling disk 403 and the second coupling disk 404 by means of magnetic attraction of the magnets, and can ensure the stability of the first coupling disk 403 driving the second coupling disk 404 to rotate.

[0043] Please refer to Figure 3 , a concave cavity 301 that is recessed upward is provided at the bottom of the material bucket 3, and the internal dimensions of the concave cavity 301 are adapted to the outer dimensions of the stirring blade 4. When the stirring blade 4 rotates to stir and mix the liquid medicine inside the medicine pot 2, the concave cavity 301 provided at the bottom of the material bucket 3 is sleeved outside the stirring blade 4. With the restriction of the stirring blade 4, the space around the stirring blade 4 can be restricted, which is beneficial to strengthening the water flow impact formed in the concave cavity 301 when the stirring blade 4 disturbs the liquid medicine, thereby effectively improving the effect of the hydraulic pressure being stirred and mixed by the stirring blade 4 in the medicine pot 2.

[0044] Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 9 - Figure 10 , a toothed ring 6 is circumferentially provided on the cylindrical surface of the collar 502, and a first gear 601 is engaged with the outer side of the toothed ring 6. A servo motor 606 is fixed inside the base 1. A plurality of shunt round boxes 5 are evenly arranged from top to bottom. A plurality of first gears 601 are coaxially arranged from top to bottom. A second outer shell 602 sleeving the outer sides of the plurality of first gears 601 is fixed inside the base 1. A spline shaft 603 parallel to the plurality of first gears 601 is rotatably installed inside the second outer shell 602. The spline shaft 603 is in transmission connection with the drive shaft of the servo motor 606. A spline tube 604 is movably sleeved on the outer side of the spline shaft 603, and a second gear 605 is fixedly sleeved on the outer side of the spline tube 604. A battery slide rail 607 parallel to the spline shaft 603 is fixed inside the second outer shell 602, and a shaft bracket 608 is fixed on the sliding end of the battery slide rail 607. The spline tube 604 is rotatably connected with the shaft bracket 608.

[0045] When the device is in use, the staff provides rotational power through the servo motor 606 to drive the ring 502 to rotate, so as to achieve the purpose of connecting the second circular hole 503 to different return pipes 505 and the inside of the diversion circular box 5. The device has a built-in PLC controller, which can automatically adjust and control according to actual needs. When a certain ring 502 needs to be rotated, the battery slide 607 is powered on and started. Under the rotation connection between the shaft frame 608 and the spline cylinder 604, the sliding end on the battery slide 607 can drive the spline cylinder 604 and the second gear 605 fixed on its outside to move up and down during the up and down movement. The staff adjusts the second gear 605 to the corresponding position of the outside of the ring 502 that needs to be driven for rotation through the battery slide 607, so that the second gear 605 is in meshing state with the corresponding first gear 601, and then The servo motor 606 is powered on and started, driving the spline shaft 603 connected to its drive shaft to rotate, and the spline shaft 603 drives the spline cylinder 604 sleeved on the outside thereof to rotate synchronously, thereby driving the second gear 605 to rotate. By means of the meshing of the second gear 605 with the corresponding first gear 601, and the meshing of the first gear 601 with the gear ring 6, the gear ring 6 corresponding to the outside of the ring 502 is driven to rotate, and then the ring 502 is driven to rotate, so as to achieve the regulation of the connection between the second circular hole 503 and the required return pipe 505. A laser transmitter pointing to each return pipe 505 is fixedly installed in the diverter circular box 5, and a laser receiver is provided at the connection between each return pipe 505 and the first shell 504. Through the cooperation of the laser transmitter and the laser receiver, it is determined whether the second circular hole 503 is rotated into place, so as to achieve precise control of the ring 502.

[0046] During the operation of the device, with the help of the up and down movement of the sliding end of the battery slide rail 607, the second gear 605 can mesh with the first gear 601 corresponding to the outer sides of different rings 502, so that the device only needs to use a single servo motor 606 to realize the rotation control of multiple rings 502. While ensuring the precise and stable rotation control of many rings 502, the usage of servo motor 606 can be effectively reduced. It is particularly suitable for multi-station Chinese medicine boiling operations. The more stations there are, that is, the more medicine pots 2 and their corresponding diversion round boxes 5, the more servo motors 606 are saved, which can effectively reduce the manufacturing and use costs of the device.

[0047] The above are only the best implementation methods adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
