DETAILED DESCRIPTION

[0021] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described herein are exemplary only and should not be construed as limiting the present application.

[0022] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can also be present.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0024] In the process of decocting black medicinal paste, a large amount of toxic smoke containing propylene aldehyde and propionamide will be generated during the decoction process. Therefore, in the existing decoction equipment for preparing black medicinal paste, a tank type structure is usually adopted, and a stirring structure is installed in the tank for sufficient stirring. The stirring structure and the tank are not detachable during daily use. In order to improve the air tightness of the tank, the opening on the tank is very small. The inventor finds that for this design, although the smoke generated during the decoction process can be concentrated and discharged for treatment, ensuring the safety and health of the operators, due to the relatively fixed position of the stirring structure in the tank and the large size of the equipment, it is difficult for the workers to effectively clean the decoction cavity in the tank after completing the decoction, especially the blind area at the stirring paddle structure part and the bottom of the tank, which is difficult to clean and cannot meet the GMP requirements. In addition, the decoction equipment lacks a pretreatment link before the addition of yellow dan. If the yellow dan is agglomerated or unevenly distributed during addition, it is difficult for the stirring structure to stir the yellow dan due to the need to add oil and fat raw materials for stirring, resulting in a local concentration that is too high to form a clump that is difficult to disperse, thereby reducing the yield of the finished black medicinal paste.

[0025] Based on this, the inventor proposes a dan oil hot mixing device for black plaster preparation to solve the above-mentioned technical problems.

[0026] Please refer to Figures 1 to 2 The embodiment provides a dan oil hot mixing device for black plaster preparation, which comprises a support base 10, a pot body 20, a rotating support 30, a stirring assembly 40 and a lower dan assembly 50. For the convenience of description, the length direction of the support base 10 is defined as the first direction A, and the width direction of the support base 10 is defined as the second direction B. The support base 10 can be composed of a bottom plate and two spaced side plates, and the accommodating space 11 penetrating along the first direction A is formed between the two side plates to avoid interference with the rotation of the pot body 20. Of course, the support base 10 can also have other structures, such as replacing the side plates with support rods, which are not limited in detail.

[0027] Further, the pot body 20 is arranged in the accommodating space 11 and is rotationally connected with the support base 10, wherein the rotation shaft is distributed along the first direction A, that is, the pot body 20 can rotate in the second direction B. The rotating support 30 is rotationally connected with the support base 10, and the rotating support 30 can rotate towards or away from the direction of the pot body. The stirring assembly 40 is arranged at the end of the rotating support 30 away from the support base 10, wherein when the rotating support 30 rotates towards the pot body 20, the stirring assembly 40 can at least partially extend into the pot body 20 for stirring of the dan oil hot mixing. The lower dan assembly 50 is arranged on the support base 10, and the lower dan assembly 50 is used for sieving dan powder and feeding the dan powder into the pot body.

[0028] Specifically, the pot body 20 can be provided with a hemispherical mixing cavity which is open upward. The connecting part of the rotating support 30 and the support base 10 is provided with a hydraulic cylinder 33, and the rotation of the rotating support 30 is controlled by controlling the extension and retraction of the output end of the hydraulic cylinder 33. Since the end of the rotating support 30 away from the support base 10 is provided with the stirring assembly 40, the rotating support 30 is rotated to make the stirring assembly 40 rotate towards or away from the pot body 20 synchronously. During the process of black plaster melting, one end of the stirring blade of the stirring assembly 40 extends into the mixing cavity of the pot body 20, so that stirring is carried out during the melting process. After the melting is completed, the stirring assembly 40 is lifted upward by the rotating support 30, that is, the stirring assembly 40 is separated from the mixing cavity, so that the pot body 20 and the stirring assembly 40 can be easily cleaned.

[0029] For the lower Dan assembly 50, set on one side of the support base 10, the lower Dan assembly 50 can include Dan powder screening structure and quantitative feeding structure, for the Dan powder screening structure can be set multi-layer screen and vibration structure, for the quantitative feeding structure can include a rotating shaft connected with the support base 10, when the need for the pot to Dan, by rotating the lower Dan assembly 50, so that the bunker of the lower Dan assembly 50 moves to the pot 20 above, so as to add Dan powder.

[0030] It should be noted that, for the rotation of the pot 20 can be controlled by the motor, in order to control the whole mixing device 100, the control console 60 can also be set on the side end of the support base 10, the control console 60 has oil temperature display and stirring speed display window, at the same time, the control console 60 can also set the vibration switch, to control the Dan powder screening of the lower Dan assembly 50, and the control console 60 can also set the arm switch, the arm switch, the discharge switch and the reset switch, to control the rotation of the pot 20 and the rotating support 30.

[0031] The mixing device 100 in the embodiment, by rotating the pot 20 on the support base 10, so as to facilitate the transfer of mixed black ointment from the pot 20, by setting the rotating support 30 and the stirring assembly 40, wherein the stirring blade of the stirring assembly 40 can extend into the pot 20, when the black ointment is mixed and cooked, by controlling the rotation of the rotating support 30, after the cooking is completed, the stirring assembly 40 is completely transferred out of the pot 20 cavity, so as to eliminate the cleaning blind area, so as to facilitate the effective cleaning of the stirring assembly 40 and the pot 20 and other structures, to meet the GMP requirements, by setting the lower Dan assembly 50, without manual Dan, and the lower Dan assembly 50 can further vibrate the Dan powder, so as to make the feeding more uniform, improve the yield of black ointment.

[0032] At the same time, the mixing device 100 of the embodiment can also collect the temperature change curve of the pot during the black ointment cooking process, specifically, by setting double high precision temperature control device in the jacket and stirring paddle, precise temperature control is realized, because the Dan temperature is a key parameter, the Dan oil reaction is not complete when the temperature is too low, and the temperature is too high, which is easy to fire, by precise temperature sensor and recorder, the whole temperature curve recording is realized, which is convenient for process supervision and traceability.

[0033] Please refer to Figures 3 to 6The improved dan oil hot mixing device for black plaster preparation comprises a supporting base 10, a pot body 20, a rotating support 30, a stirring assembly 40 and a lower dan assembly 50. For the convenience of description, the length direction of the supporting base 10 is defined as the first direction A, and the width direction of the supporting base 10 is defined as the second direction B. The supporting base 10 can be composed of a bottom plate and two spaced side plates, and the accommodating space 11 penetrating along the first direction A is formed between the two side plates to avoid interference with the pot body 20 during rotation. Of course, the supporting base 10 can also have other structures, for example, the side plates are replaced by supporting rods, which are not limited in detail.

[0034] Further, the pot body 20 is arranged in the accommodating space 11 and rotationally connected with the supporting base 10. A turbine 11 is coaxially arranged on the rotation shaft of the pot body 20 connected with the supporting base 10. A worm 12 engaging with the turbine 11 is arranged on the supporting base 10. The rotating support 30 is rotationally connected with the supporting base 10. A supporting column 31 and a supporting plate 32 extending from one end of the supporting column 31 and towards the pot body 20 are arranged on the rotating support 30. The stirring assembly 40 comprises a cover 41 arranged on the end of the supporting plate 32 away from the supporting column 31 and matched with the pot body 20, and a stirring structure 42 rotationally connected with the supporting plate 32 and arranged between the cover 41 and the pot body 20. When the rotating support 30 rotates, the cover 41 can be selectively arranged on the pot body 20 to form a closed mixing cavity.

[0035] It should be noted that the pot body 20 can be provided with a hemispherical mixing cavity 21 opening upward. Through the rotation of the rotating support 30, the stirring assembly 40 can rotate along the rotation shaft of the rotating support 30, so that the cover 41 and the stirring assembly 40 are synchronously rotated towards or away from the pot body 20. The lower dan assembly 50 is arranged to control the addition of yellow dan into the pot body 20. Specifically, before the black plaster is prepared, the rotating support 30 is controlled to rotate away from the pot body 20, so that the pot cover 41 and the stirring structure 42 are separated from the pot body 20. After being separated to a preset position, medicinal materials and vegetable oil are added into the pot body 20 and preheated by the electric heating rod 22. Then the rotating support 30 is controlled to rotate towards the pot body 20, so that the stirring structure 42 extends into the mixing cavity 21. At the same time, the pot cover 41 can just close the opening at the top of the pot body 20, so that the mixing cavity 21 is in a sealed state. Then the preparation and stirring mixing process is carried out. The generated smoke can be discharged from the smoke exhaust pipe 411 arranged on the cover 41 for centralized treatment, so as to avoid harming the health of the operator.

[0036] It should be noted that, after the black plaster is boiled, the rotating support 30 is controlled to rotate by a certain angle away from the pot body 20, so that the stirring assembly 40 is separated from the black plaster, and then after the black plaster remaining on the stirring structure 42 falls into the pot body 20, the rotating support 30 is further controlled to rotate away from the pot body 20, so that the pot body 20 does not interfere with the stirring structure 42 and the cover 41 during the rotation process. Then the pot body 20 is controlled to rotate along the rotating shaft away from the rotating support 30, and the collecting device is placed in front of the flow guide groove 211 of the pot body 20, so that the black plaster flows from the flow guide groove 211 to the collecting device, thereby completing the transfer of the black plaster from the pot body 20.

[0037] The mixing device 100 in the embodiment is connected to the pot body 20 by rotating on the support base 10. A worm gear is arranged at the rotating connection between the pot body 20 and the support base 10. The pot body 20 is tilted and returned by rotating the worm 12, thereby facilitating the transfer of the mixed black plaster from the pot body 20. The rotating support 30 and the stirring assembly 40 are arranged. The stirring assembly 40 includes a cover 41 matched with the pot body 20 and a stirring structure 42 rotatably connected to the support plate 32 and arranged between the cover 41 and the pot body 20. After mixing and boiling, the rotating support 30 is controlled to rotate. After the boiling is completed, the cover 41 and the stirring structure 42 are completely transferred out of the cavity of the pot body 20, thereby eliminating the cleaning blind area and facilitating the effective cleaning of the stirring structure 42 and the pot body 20 and other structures to meet the GMP requirements. When the cover 41 is closed on the pot body 20, a relatively closed mixing cavity 21 is formed, thereby enabling the generated smoke to be concentrated and treated to avoid overflow. The setting of the lower dan assembly 50 eliminates the need for manual lower dan. The disintegration and screening structure 52 arranged in the lower dan assembly 50 can further crush and disintegrate the yellow dan to be added, thereby effectively avoiding uneven addition of the yellow dan and improving the yield of the finished black plaster.

[0038] Optionally, in combination with Figure 4 The pot body 20 can be provided with rotating shafts on both sides in the second direction B. Bearings 13 connected with the rotating shafts can be arranged on both sides of the support base 10. Thus, the worm 11 is arranged at one end of the rotating shaft extending out of the bearing 13. The worm 12 is arranged along the first direction A on the side wall of the support base 10 and is meshingly connected with the worm 11. The arrangement of the bearing 13 facilitates the tilting of the pot body 20 by the worker. In order to facilitate the rotation of the worm 12, a rocker can be arranged at one end of the worm 12. When the rocker is rotated clockwise or counterclockwise, the pot body 20 is controlled to rotate along the rotating shaft, thereby tilting or returning the pot body 20 in the first direction A.

[0039] Of course, the rocker can also be replaced by a motor for control, and the specific selection can be made according to the actual demand. The bottom of the pot 20 is provided with an electric heating rod 22. The electric heating rod 22 can be provided in a disc shape at the bottom of the pot 20. It can be understood that the electric heating rod 22 can be obtained from the prior art, and its structure and principle will not be described here.

[0040] Please continue to combine Figure 5 The rotating support 30 is coaxially provided with a gear 301 on the rotating shaft connected with the support base 10. The surface of the support base 10 is provided with a telescopic motor 13. The output shaft of the telescopic motor 13 is connected with a rack 14 which is linearly engaged with the gear 301. Specifically, the telescopic motor 13 and the rack 14 can be fixed by the support structure provided on the surface of the support base. The distribution direction of the output shaft of the telescopic motor 13 and the rack 14 is along the first direction A. Therefore, when the rack 14 moves horizontally forward and backward in the first direction A, the rotating shaft of the rotating support 30 rotates in the second direction B, thereby controlling the rotation of the rotating support 30.

[0041] In some embodiments, please refer to Figures 6 to 8 The medicine cover 51 is provided with a crushing cavity 512 which is communicated with the discharge port 511. The side wall of the medicine cover 51 at the crushing cavity 512 is provided with a conveying pipe 513 which is used to input the yellow into the crushing cavity 512. The dispersing and screening structure 52 includes a first driving member 521 provided on the outer surface of the medicine cover 51, and a crushing rod 522 connected with the output shaft of the first driving member 521 and extending into the crushing cavity 512. The crushing rod 522 is circumferentially provided with a plurality of shearing blades 523.

[0042] It should be noted that the first driving member 521 can be a servo motor. The plurality of shearing blades 523 are distributed on the surface of the crushing rod 522 along the length direction of the crushing rod 522. One end of the shearing blade 523 is connected with the crushing rod 522, and the other end extends towards the wall of the medicine cover 51. In this way, manual feeding of the yellow is no longer needed, and the safety and health of the operator are protected. When the yellow fed through the conveying pipe 513 falls into the crushing cavity 512, the shearing blades 523 can further disperse the small pieces of yellow, so that they form powder and are added into the mixing cavity 21 of the cylinder, thereby avoiding the addition of the caked yellow into the mixing cavity 21, which causes the local yellow concentration to be too high and forms a mass which is not easy to disperse, thereby reducing the yield of the finished black ointment.

[0043] In order to further avoid the blocky yellow lead into the mixing cavity 21 in the pot 20, the screen disc 524 and the disturbing ring 525 are sequentially sleeved on the end of the crushing rod 522 away from the first driving member 521, wherein the screen disc 524 is rotationally connected with the crushing rod 522, and the first protrusion 5241 is arranged on the surface edge of the screen disc 524 towards the disturbing ring 525; the disturbing ring 525 is fixedly connected with the crushing rod 522, and the second protrusion 5251 is arranged on the surface edge of the disturbing ring 525 towards the screen disc 524; when the disturbing ring 525 rotates, the screen disc 524 reciprocates along the axial direction of the crushing rod 522.

[0044] Specifically, the first protrusion 5241 and the second protrusion 5251 can be arranged in the same shape, for example, the shapes of the first protrusion 5241 and the second protrusion 5251 are semicircular; the number of the first protrusion 5241 and the second protrusion 5251 can be four or six, which is not limited specifically; when the crushing rod 522 rotates, the disturbing ring 525 is driven to rotate, and since the screen disc 524 is fixedly connected with the medicine cover 51, the relative rotation occurs between the screen disc 524 and the disturbing ring 525; when the first protrusion 5241 and the second protrusion 5251 collide, the screen disc 524 reciprocates up and down, thereby realizing the screening of the yellow lead and further avoiding the blocky yellow lead from falling into the mixing cavity 21 in the pot 20.

[0045] Optionally, continuing to refer to Figure 6 , the circumferential side wall of the screen disc 524 extends to be attached to the inner side wall of the medicine cover 51, and the top surface edge of the screen disc 524 is provided with an elastic reset member 5242, the other end of the elastic reset member 5242 is fixedly connected with the medicine cover 51; through the arrangement that the circumferential side wall of the screen disc 524 extends to be attached to the inner side wall of the medicine cover 51, the blocky yellow lead can be avoided from falling into the mixing cavity 21; at the same time, the screen disc 524 also separates the crushing cavity 512 from the discharge port 511; the structure of the elastic reset member 5242 can be arranged in a structure similar to a hydraulic cylinder, that is, a sleeve is arranged on the screen disc 524, a spring is arranged in the sleeve, so that the spring can only stretch and contract in the sleeve; at the same time, the inner wall of the medicine cover 51 is connected to one end of the spring through a connecting rod; in this way, when the screen disc 524 reciprocates up and down, the elastic reset member 5242 can provide an additional force, so that the speed of the screen disc 524 during the up and down movement is faster, thereby avoiding the yellow lead from blocking the screen disc 524, and also allowing the blocky yellow lead to be cut and scattered again by the shearing blade 523.

[0046] It should be noted that the mesh of the screen disc 524 can be selected according to actual needs; the crushing cavity 512 can be arranged in a cylindrical cavity, so that the screen disc 524 can move up and down conveniently; the discharge port 511 can be arranged in a horn shape, so that the yellow lead in powder form after screening can fall into the mixing cavity 21 conveniently.

[0047] In some embodiments, please refer to Figure 9 The second driving member 302 is arranged on the rotating support 30, which can be a motor. A through cavity is arranged inside the support column 31 along the central axis direction. The output shaft of the second driving member 302 can extend along the through cavity to the position of the support plate 32, and a first pulley 303 is arranged. The second pulley 421 is arranged on the rotating shaft of the stirring mechanism 42 which is rotationally connected to the support plate 32. The first pulley 303 is in transmission connection with the second pulley 421 through a first transmission belt 304. In this way, the rotation control of the stirring mechanism 42 is realized, and the structure is more integrated, thereby effectively avoiding the interference between the stirring mechanism 42 and the pot body 20.

[0048] Please refer to Figure 10 and Figure 11 The surface of the support plate 32 close to the medicine cover 51 is provided with a reciprocating screw 321. One end of the reciprocating screw 321 is in transmission connection with the second driving member 302 through a pulley. The other end of the reciprocating screw 321 is connected with a shutter 322 which is matched with the discharge port 511. When the reciprocating screw 321 rotates, the shutter 322 periodically covers the discharge port 511. Specifically, a third pulley 422 is arranged on the rotating shaft of the stirring mechanism 42, which is coaxial with the second pulley 421 along the length direction of the rotating shaft. A fourth pulley 323 is arranged on the upper end of the reciprocating screw 321. The third pulley 422 and the fourth pulley 323 are connected through a second transmission belt 324. The other end of the reciprocating screw 321 is connected with the shutter 322 which is matched with the discharge port 511 of the medicine cover 51. When the second driving member 302 operates, the stirring mechanism 42 and the reciprocating screw 321 are synchronously driven to operate.

[0049] In this way, the reciprocating screw 321 is arranged to operate, thereby controlling the shutter 322 to periodically cover the discharge port 511, i.e. periodically controlling the discharge of the discharge port 511. Therefore, when the black plaster is boiled, the yellow dan can be periodically added while stirring, so that the yellow dan is more evenly added, and the distribution is more uniform. Therefore, the yield of the finished product of the black plaster is improved, and a large amount of smoke is avoided.

[0050] It should be noted that the reciprocating screw 321 can be obtained from the prior art, and its specific structure and functional principle are not described here. The shutter 322 can be arranged in a conical frustum shape which is matched with the shape of the discharge port 511.

[0051] In some embodiments, please refer to Figure 11The stirring structure 42 comprises a first stirring rod 423 and a second stirring rod 424 arranged at an angle with the first stirring rod 423, and the first stirring rod 423 and the second stirring rod 424 are respectively provided with a stirring paddle 425 at an end away from the support plate 32, and the surface of the first stirring rod 423 or the second stirring rod 424 close to the stirring paddle 425 is provided with a temperature sensor 426.

[0052] It should be noted that the bottom end of the stirring paddle 425 can be provided with a circular arc shape, so that the stirring paddle 425 can be close to the wall of the mixing cavity 21 in the pot body 20 for stirring, thereby effectively avoiding the phenomenon of paste bottom of mixed medicinal materials, and the angle between the first stirring rod 423 and the second stirring rod 424 can be 10°, 25° or 30°, which is selectively designed according to actual needs.

[0053] In the embodiment, by arranging the first stirring rod 423 and the second stirring rod 424 at an angle, the stirring process can be more uniform and sufficient, and at the same time, the cleaning of the equipment is facilitated, especially after production, the pot body 20 can be tilted by rotating the stirring structure 42, thereby facilitating further cleaning, thereby meeting the requirements of GMP, and by arranging the temperature sensor 426, the temperature sensor 426 can directly collect the temperature of the black ointment semi-finished product in the mixing cavity 21, realize the whole process temperature curve recording, and facilitate process supervision and traceability.
