Description

Technical Field

[0001] This application relates to the field of electric heating mixing tank technology, specifically to an electric heating and heat preservation mixing tank. Background Technology

[0002] Electric heating mixing tanks, also known as aqueous phase tanks, are widely used in industries such as coatings, pharmaceuticals, building materials, chemicals, pigments, resins, food, and scientific research. In the pharmaceutical industry, the mixing and preparation of drugs is an important step in pharmaceutical work, so mixing tanks are needed to mix drugs.

[0003] Existing mixing tanks cannot effectively circulate and pulverize solid drugs before mixing, resulting in some clumps of drugs not being broken up. This can easily affect the mixing effect with other drugs during subsequent mixing operations.

[0004] To address the aforementioned technical issues, patent CN210449137U discloses a drug heating and stirring reaction device for pharmacology, comprising a base, a pressurizing device mounted on the base, and a stirring reaction vessel. An automatic speed-regulating motor is mounted at the top of the stirring reaction vessel, and the output shaft of the automatic speed-regulating motor is connected to a stirring shaft. The stirring shaft passes through the top of the stirring reaction vessel and extends to the bottom. A support rod is connected to the stirring shaft, and the support rod is equipped with stirring blades and a side wall scraper. A bottom scraper is located at the bottom of the stirring shaft. This invention facilitates enhanced mixing of the drug solution; simultaneously, the pressurizing device and electric heating device ensure more suitable temperature and pressure of the materials during stirring, resulting in better drug reaction; furthermore, the side wall scraper and bottom scraper can scrape away deposits on the inner wall and bottom of the stirring reaction vessel, thereby preventing material deposition and enhancing the mixing effect.

[0005] However, the above technical solution has the following drawbacks:

[0006] (1) There is no crushing and screening mechanism for solid drugs, which makes it more difficult to mix with other drugs when some solid drugs clump together. Summary of the Invention

[0008] To achieve the above objectives, the technical solution adopted in this application is as follows: an electrically heated and heat-insulating mixing tank, comprising a mixing tank body, a support fixedly connected to the lower end of the mixing tank body, a stirring shaft rotatably arranged in the middle of the upper end of the mixing tank body, multiple stirring blades fixedly connected to both sides of the stirring shaft, and a circulating screening and pulverizing mechanism for pulverizing and screening solid drugs provided at the upper end of the mixing tank body;

The connection between the first eccentric block, the second gear, and the slider is rotatably connected to the displacement plate via a pin. A second rack is fixedly connected to the upper side of the rear end face of the inner cavity wall of the crushing box. The second rack and the second gear mesh with each other. A second motor is fixedly connected to the rear end of the upper side of the right end face of the crushing box. A reciprocating screw is fixedly connected to the output end of the second motor. The reciprocating screw is threadedly connected to the displacement plate.

[0011] Preferably, a spring is sleeved on the lower side of the front sliding column, the lower end of the spring is fixedly connected to the blade plate, the upper end of the spring is fixedly connected to the displacement plate, and an extrusion plate is fixedly connected to the upper end face of the sliding column.

[0012] Preferably, a spring damper is fixedly connected to the rear left side of the upper end face of the mixing tank body, a rectangular plate is fixedly connected to the piston end of the spring damper, a second eccentric block is rotatably arranged at the rear left side of the upper end face of the mixing tank body, a fourth motor is fixedly connected to the rear left side of the upper end face of the mixing tank body, and the output end of the fourth motor is fixedly connected to the second eccentric block.

[0013] Preferably, electric heating plates are provided on both sides of the inner wall of the mixing tank body, and an insulation layer is provided on the outer wall of the mixing tank body, the insulation layer being made of ceramic fiber cotton.

[0014] Preferably, an L-shaped plate is rotatably mounted on the upper end of the stirring shaft. Limiting rods are slidably connected to both ends of the left side of the L-shaped plate. The lower ends of the limiting rods are fixedly connected to the main body of the mixing tank. A first bevel gear is fixedly mounted on the upper end of the stirring shaft. A second bevel gear and a first gear are rotatably mounted on the right side of the upper end of the L-shaped plate. A first rack is fixedly connected to the middle of the upper surface of the mixing tank main body, and the first rack meshes with the first gear. A third motor is fixedly connected to the middle of the upper surface of the mixing tank main body. A crank is fixedly connected to the output end of the third motor. A rectangular block is rotatably mounted at the lower end of the crank. A sliding groove rod is inserted into the rectangular block and slidably connected to it. The front end of the sliding groove rod is fixedly connected to the L-shaped plate.

[0015] Preferably, a liquid injection port is provided on the upper right side of the mixing tank body, which can be used to add liquid medicines, and a discharge port is provided in the lower middle part of the mixing tank body, which can be used to discharge the mixed medicines.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] (1) The solid medicine to be added to the main body of the mixing tank is placed on the upper part of the filter screen in the crushing box. Then, the fourth motor and the second motor are started simultaneously. The second motor drives the reciprocating screw to rotate continuously, causing the displacement plate to move back and forth between the leftmost and rightmost ends inside the crushing box. When the displacement plate moves, it drives the slider to slide left and right through the pin shaft. When the slider slides left and right, the second gear rotates continuously under the action of the second rack, which causes the first eccentric block to rotate continuously. The first eccentric block continuously contacts the extrusion plate, causing the extrusion plate to drive the sliding column to move up and down, and then return to its original position under the action of the spring. This causes the blade plate and the blade to form a reciprocating motion, which can cut and crush the solid medicine on the upper part of the filter screen. At the same time, the second eccentric block rotates continuously under the action of the fourth motor. By maintaining continuous contact with the rectangular plate, the pulverizing chamber moves up and down repeatedly with the help of the spring damper, causing it to vibrate and screen the medicine. Under the pulverizing action, only medicines smaller than the filter mesh openings can pass through the filter and reach the main body of the mixing tank. This ensures that all solid medicines passing through the filter are granular before mixing. This process provides a cyclical cutting and screening effect for solid medicines before mixing, ensuring that all solid drugs are broken down and that the solid medicines falling into the main body of the mixing tank are granular smaller than the filter mesh openings. This prevents clumping of solid medicines during subsequent mixing, which would affect the mixing effect with other medicines, thus providing a better foundation for subsequent mixing operations.

[0018] (2) The electric heating plate can be used to heat the medicine inside the mixing tank to achieve the effect of decocting medicine. In addition, the ceramic fiber cotton insulation layer can effectively prevent heat loss, has a good heat preservation effect on the medicine, and also has a certain sound insulation effect, reducing the noise pollution generated by the mixing operation.

[0019] (3) When all the medicines to be mixed are inside the mixing tank, the third motor can be turned on to drive the crank to rotate, so that the crank drives the rectangular block to make a circular motion, so that the rectangular block slides inside the sliding rod, and the L-shaped plate slides back and forth on the limiting rod, so that the stirring shaft moves up and down back and forth. When the L-shaped plate moves, the first gear rotates under the action of the first rack, so that the second bevel gear drives the first bevel gear to rotate, so that the stirring shaft rotates, and the stirring blades move up and down back and forth while also rotating back and forth, so that the height and rotation direction of the stirring blades can be changed. When the height of the stirring blades changes, medicines at different heights can be stirred, expanding the stirring range. In addition, by using the back and forth rotation of the stirring blades, the medicines can be prevented from always following the stirring blades under the action of inertia. The medicines can be impacted by the back and forth movement of the stirring blades, further improving the stirring force. Thus, the medicines can be stirred in real time with the height and direction that can be changed, expanding the stirring range and intensifying the stirring force, improving the overall stirring effect.

[0030] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0031] The existing technology has the following drawbacks:

[0032] (1) The existing mixing tanks cannot perform a cyclic pulverizing effect on solid drugs before mixing, resulting in some clumps of drugs not being broken up, which can easily affect the mixing effect with other drugs during subsequent mixing.

[0033] As an improvement, such as Figures 1-6 As shown, the preferred embodiment of this application is as follows:

[0034] An electrically heated and heat-insulating mixing tank includes a mixing tank body 1, a support 4 fixedly connected to the lower end of the mixing tank body 1, a stirring shaft 6 rotatably arranged in the middle of the upper end of the mixing tank body 1, multiple stirring blades 7 fixedly connected to both sides of the stirring shaft 6, and a circulating screening and pulverizing mechanism for pulverizing and screening solid drugs provided at the upper end of the mixing tank body 1.

[0035] The circulating screening and pulverizing mechanism includes a pulverizing box 11 slidably connected to the upper left side of the mixing tank body 1. A filter screen 12 is fixedly connected to the middle of the inner wall of the pulverizing box 11. A slide rod 36 is fixedly connected to the rear side of the left and right end faces of the inner wall of the pulverizing box 11. A displacement plate 25 is slidably connected to the slide rod 36. A slide column 28 is slidably connected to the front end of the displacement plate 25. A blade plate 14 is fixedly connected to the lower end face of the slide column 28. Multiple blades 13 are fixedly connected to the lower end face of the blade plate 14.

[0036] like Figure 2 , Figure 3 , Figure 6 As shown, in this embodiment, a slider 23 is slidably connected to the upper side of the rear end face of the inner cavity wall of the crushing box 11. The middle of the front end face of the slider 23 is rotatably connected to a first eccentric block 26 and a second gear 24 via a pin. The connection between the first eccentric block 26, the second gear 24 and the slider 23 is rotatably connected to the displacement plate 25 via a pin. A second rack 22 is fixedly connected to the upper side of the rear end face of the inner cavity wall of the crushing box 11. The second rack 22 and the second gear 24 mesh with each other. A second motor 16 is fixedly connected to the upper rear end of the right end face of the crushing box 11. A reciprocating screw 37 is fixedly connected to the output end of the second motor 16. The reciprocating screw 37 is threadedly connected to the displacement plate 25.

[0037] A spring 29 is fitted on the lower side of the front sliding column 28. The lower end of the spring 29 is fixedly connected to the blade plate 14, and the upper end of the spring 29 is fixedly connected to the displacement plate 25. A pressing plate 27 is fixedly connected to the upper end face of the sliding column 28.

[0038] A spring damper 30 is fixedly connected to the rear left side of the upper end face of the mixing tank body 1. A rectangular plate 31 is fixedly connected to the piston end of the spring damper 30. A second eccentric block 33 is rotatably set at the rear left side of the upper end face of the mixing tank body 1. A fourth motor 32 is fixedly connected to the rear left side of the upper end face of the mixing tank body 1. The output end of the fourth motor 32 is fixedly connected to the second eccentric block 33.

[0039] Specifically, when it is necessary to stir solid medicines, the solid medicines to be added to the mixing tank body 1 can be placed on the upper end of the filter screen 12 inside the crushing box 11. Then, the fourth motor 32 and the second motor 16 are started simultaneously. The second motor 16 drives the reciprocating screw 37 to rotate continuously, causing the displacement plate 25 to move back and forth between the leftmost and rightmost ends inside the crushing box 11. When the displacement plate 25 moves, it can drive the slider 23 to slide left and right through the pin shaft. When the slider 23 slides left and right, the second gear 24 rotates continuously under the action of the second rack 22, which causes the first eccentric block 26 to rotate continuously. The first eccentric block 26 continuously contacts the extrusion plate 27, causing the extrusion plate 27 to drive the sliding column 28 to move up and down, and return to its original position under the action of the spring 29. This causes the blade plate 14 and the blade 13 to form a reciprocating motion, which can cut and crush the solid medicines on the upper end of the filter screen 12. At the same time, Under the action of the fourth motor 32, the second eccentric block 33 rotates continuously, making it continuously contact the rectangular plate 31. This causes the pulverizing box 11 to move up and down reciprocally with the help of the spring damper 30, thus creating vibration in the pulverizing box 11. This screens the medicine, and under the action of pulverization, only medicine smaller than the through holes of the filter screen 12 can pass through the filter screen 12 and reach the interior of the mixing tank body 1. This ensures that all solid medicines passing through the filter screen 12 are granular before stirring and mixing. Thus, the solid medicines are cyclically cut, crushed, and screened before stirring, ensuring that all solid medicines are crushed. Furthermore, it ensures that the solid medicines falling into the mixing tank body 1 are granular smaller than the through holes of the filter screen 12, avoiding the situation where the solid medicines clump together and affect the mixing effect with other medicines during subsequent stirring. This provides a better foundation for subsequent stirring.

[0040] like Figure 1 As shown, in this embodiment, electric heating plates 8 are provided on both sides of the inner wall of the mixing tank body 1, and a heat insulation layer 2 is provided on the outer wall of the mixing tank body 1. The heat insulation layer 2 is made of ceramic fiber cotton.

[0041] Specifically, the electric heating plate 8 can be used to heat the medicine inside the mixing tank 1 to achieve the effect of decocting medicine. In addition, the ceramic fiber cotton insulation layer 2 can effectively prevent heat loss, has a good heat preservation effect on the medicine, and also has a certain sound insulation effect, reducing the noise pollution generated by the mixing operation.

[0042] like Figure 1 and Figure 2As shown, in this embodiment, an L-shaped plate 17 is rotatably mounted on the upper end of the stirring shaft 6. Limiting rods 10 are slidably connected to both ends of the left side of the L-shaped plate 17. The lower end of the limiting rods 10 is fixedly connected to the mixing tank body 1. A first bevel gear 19 is fixedly mounted on the upper end of the stirring shaft 6. A second bevel gear 20 and a first gear 15 are rotatably mounted on the right side of the upper end of the L-shaped plate 17. A first rack 9 is fixedly connected to the middle of the upper end face of the mixing tank body 1. The first rack 9 and the first gear 15 mesh with each other. A third motor 18 is fixedly connected to the middle of the upper end face of the mixing tank body 1. A crank 21 is fixedly connected to the output end of the third motor 18. A rectangular block 35 is rotatably mounted on the lower end of the crank 21. A sliding groove rod 34 is inserted into the rectangular block 35 and slidably connected to it. The front end of the sliding groove rod 34 is fixedly connected to the L-shaped plate 17.

[0043] A liquid inlet 3 is provided on the upper right side of the mixing tank body 1. The liquid inlet 3 can be used to add liquid medicines. A discharge outlet 5 is provided in the middle of the lower part of the mixing tank body 1. The discharge outlet 5 can be used to discharge the mixed medicines.

[0044] Specifically, once all the medicines to be mixed are inside the mixing tank body 1, the third motor 18 can be turned on to drive the crank 21 to rotate. This crank 21 causes the rectangular block 35 to move in a circular motion, allowing the rectangular block 35 to slide inside the sliding groove rod 34. This causes the L-shaped plate 17 to slide back and forth on the limiting rod 10, thus moving the mixing shaft 6 up and down. Furthermore, as the L-shaped plate 17 moves, the first gear 15 rotates under the action of the first rack 9, causing the second bevel gear 20 to drive the first bevel gear 19 to rotate. This, in turn, causes the mixing shaft 6 to rotate, resulting in the mixing blades 7 moving up and down. Simultaneously, the reciprocating rotation allows for changes in the height and direction of rotation of the stirring blade 7. When the height of the stirring blade 7 changes, it can stir medicines at different heights, expanding the stirring range. Furthermore, the reciprocating rotation of the stirring blade 7 prevents the medicines from constantly following the stirring blade 7 due to inertia. Instead, the reciprocating movement of the stirring blade 7 creates an impact with the medicines, further increasing the stirring force. Thus, it provides a stirring effect where the height and direction of the medicines can be changed in real time, expanding the stirring range and intensifying the stirring force, thereby improving the overall stirring effect.

[0045] The working principle of this application is as follows: The liquid medicine to be mixed is added into the mixing tank body 1 through the injection port 3. The solid medicine to be added into the mixing tank body 1 is placed on the upper end of the filter screen 12 in the pulverizing box 11. Then, the fourth motor 32 and the second motor 16 are started simultaneously. The second motor 16 drives the reciprocating screw 37 to rotate continuously, causing the displacement plate 25 to move back and forth between the leftmost and rightmost ends inside the pulverizing box 11. When the displacement plate 25 moves, it can drive the slider 23 to slide left and right through the pin shaft. When the slider 23 slides left and right, the second gear 24 is continuously rotated under the action of the second rack 22, which causes the first eccentric block 26 to rotate continuously. The first eccentric block 26 continuously contacts the extrusion plate 27, causing the extrusion plate 27 to drive the sliding column 2. The blade plate 14 and blade 13 move up and down and return to their original position under the action of spring 29, thus creating a reciprocating motion. This cuts and crushes the solid medicine on the upper part of the filter screen 12. Simultaneously, under the action of the fourth motor 32, the second eccentric block 33 rotates continuously, keeping it in continuous contact with the rectangular plate 31. This causes the crushing box 11 to move up and down in conjunction with the spring damper 30, creating vibration in the crushing box 11. This screens the medicine, and under the crushing action, only medicine smaller than the through holes of the filter screen 12 can pass through the filter screen 12 and reach the interior of the mixing tank 1. This ensures that all solid medicine passing through the filter screen 12 is in granular form before stirring and mixing. Thus, the solid medicine is pre-mixed before stirring. The cyclic cutting and crushing screening effect ensures that all solid drugs are crushed, and that the solid drugs falling into the mixing tank body 1 are all granular with a diameter smaller than the through holes of the filter screen 12. This avoids the situation where solid drugs clump together during subsequent mixing, which would affect the mixing effect with other drugs, thus providing a good foundation for subsequent mixing. After all the drugs to be mixed are inside the mixing tank body 1, the third motor 18 can be turned to drive the crank 21 to rotate, causing the crank 21 to drive the rectangular block 35 to make a circular motion. The rectangular block 35 slides inside the sliding rod 34, causing the L-shaped plate 17 to slide back and forth on the limiting rod 10. This allows the stirring shaft 6 to move up and down. When the L-shaped plate 17 moves, the first gear 15 moves along the first rack 9. Under the action of the first bevel gear 19, the second bevel gear 20 rotates, causing the stirring shaft 6 to rotate. This causes the stirring blade 7 to move up and down and rotate back and forth simultaneously, thus changing the height and direction of rotation of the stirring blade 7. When the height of the stirring blade 7 changes, it can stir medicines at different heights, expanding the stirring range. Furthermore, the reciprocating rotation of the stirring blade 7 prevents the medicines from always following the stirring blade 7 due to inertia. The reciprocating movement of the stirring blade 7 creates an impact with the medicines, further increasing the stirring force. Thus, it can achieve a stirring effect where the height and direction of the medicines can be changed in real time, expanding the stirring range and intensifying the stirring force, thereby improving the overall stirring effect.The electric heating plate 8 can heat the medicine inside the mixing tank 1 to achieve the effect of decocting medicine. Furthermore, the ceramic fiber cotton insulation layer 2 effectively prevents heat loss, providing good heat preservation for the medicine and also offering some sound insulation, reducing noise pollution generated during the mixing operation.
