Description

TECHNICAL FIELD

[0001] The present application relates to the field of homogenizer, in particular to a double-shaft bidirectional rotation homogenizer. BACKGROUND

[0002] The homogenizer is mainly used for tissue dispersion in biotechnology field, sample preparation in medical field, enzyme treatment in food industry, pesticide residue and veterinary drug residue detection in food, and in pharmaceutical industry, cosmetic industry, paint industry and petrochemical industry, etc.

[0003] In the pharmaceutical industry, some drugs need to put multiple raw materials into the homogenizer for heating and stirring to accelerate the reaction between the raw materials and make the liquid raw materials and solid or powder raw materials fully mixed. The equipment used in the stirring process generally includes a stirring rod and a motor for driving the stirring rod to rotate. Since the raw materials need to be put into the homogenizer and stirred in isolation from the air to prevent external pollutants from penetrating into the raw materials.

[0004] Isolating air makes the raw materials in the homogenizer isolated from the outside world, and the raw materials cannot be added at will during the process. The prepared raw materials need to be put into the reaction kettle at one time. For the stirring equipment, especially some single stirring structure, the pressure is large during the early stage of stirring, and the stirring of the raw materials is realized by simply inputting high power. Long-term use of this method will cause damage to the motor, and the stirring efficiency is low, which leads to the fact that the raw materials cannot be evenly distributed in a short time.

[0005] Therefore, the double-shaft bidirectional rotation homogenizer is proposed to solve the above problems. SUMMARY

[0006] In order to make up for the shortcomings of the prior art and solve at least one technical problem in the background art.

[0007] The technical scheme adopted by the present application to solve its technical problems is: the double-shaft bidirectional rotation homogenizer, comprising a base, a kettle body is arranged on one side of the base, a lifting unit is arranged on one side of the kettle body, the lifting unit comprises a base, air cylinders are symmetrically arranged in the base, lifting rods are fixedly connected to the output ends of the air cylinders, a support plate is fixedly connected to the lifting rods, a cover body is arranged on the upper surface of the support plate, and a driving unit is arranged in the cover body; an agitating unit is arranged in the kettle body and connected to the lower surface of the support plate through a kettle cover; the driving unit comprises a first motor and a second motor; the agitating unit comprises a middle shaft and side shafts; the kettle cover is fixedly connected to the lower surface of the support plate, the middle shaft penetrates through the kettle cover and is fixedly connected to the output end of the first motor in the cover body, a driven gear is rotatably connected to the outer circle of the upper end of the middle shaft, and a ring body is rotatably connected to the outer circle of the lower end of the middle shaft; the side shafts are symmetrically fixedly connected between the driven gear and the ring body and are symmetrically arranged on the two sides of the middle shaft, a driving gear is engaged with the driven gear, and the driving gear is fixedly connected to the output end of the second motor in the cover body; a plurality of first plates are fixedly connected to the inner side walls of the side shafts and are arranged in an inclined manner; a plurality of second plates are fixedly connected to the outer circle of the middle shaft and are arranged in an inclined manner; for the raw materials just put into the kettle body, the first plates and the second plates rotate in opposite directions, so that the horizontal movement effect of the raw materials can be improved, the resistance of the raw materials to the first plates and the second plates is reduced, that is, by arranging the first plates and the second plates in an upper-lower manner, the raw materials are stirred in layers and are stirred in opposite directions, and under the condition that the output power of the motor remains unchanged, the double-shaft bidirectional rotation homogenizer can not only realize the stirring of the materials but also protect the motor and make the motor operate in a good state for a long time.

[0008] Preferably, a scraping unit is arranged on the outer side wall of the side shaft; the scraping unit comprises a scraper and a fixed block; the two ends of the scraper are rotatably connected to the fixed block through torsional springs, the fixed block is fixed on the side shaft, and the scrapers on the two side shafts are arranged in an upper-lower staggered manner; when the raw materials are stirred, some of the raw materials adhere to the inner side wall of the kettle body, if not treated in time, the raw materials cannot participate in the mixing of the raw materials, so that the stable raw material ratio is not uniform, therefore, the scraping unit is arranged on the side shaft, the edge of the scraper is attached to the inner surface of the kettle body and moves, the raw materials on the inner surface of the kettle body are penetrated and dropped while the scraper moves, the uniformity of the raw material mixing is improved, and the scraper is arranged in an upper-lower staggered manner, so that more areas on the inner side of the kettle body can be considered and the scraping is more thorough.

[0009] Preferably, a hollow cylinder is fixed to the lower end of the driven tooth. Multiple feed inlets are opened on the outer ring of the cylinder. A hollow ring (number one) is fitted onto the outer ring of the cylinder. The inner ring of the ring (number one) is rotatably and sealingly connected to the surface of the cylinder, and multiple outlets are opened on the inner ring of the ring (number one). The outlets intermittently connect to the feed inlets, and a feed pipe is connected to the ring (number one). A tube is provided on the outer ring of the cylinder, laid along the inner side of the side shaft. Multiple spray holes are opened on the surface of the scraper, and the spray holes are connected to flexible hoses. The flexible hoses pass through the side shaft and connect to the tube. By setting the ring (number one), ... The scraper is equipped with spray holes, which can quickly rinse the vessel body after the raw materials are stirred. The feed pipe is connected to an external water pump, and water is injected into the No. 1 ring and then into the cylinder through the outlet and feed port. After that, it is distributed into the pipe body and then sprayed out from the spray holes along the pipe body and hose. With the vessel body covered by the lid, the side shaft rotates at the same time, and the water flows out from the spray holes. While rotating, it impacts the inner surface of the vessel body. The water flow directly impacts the inner side wall of the vessel body, resulting in better rinsing effect and no rinsing waste liquid splashing out and polluting the operating environment.

[0010] Preferably, the nozzle is located on the back of the scraper. As the scraper rotates, it passes through the raw material on the inner surface of the vessel. At the same time, viscous raw material or raw material containing particles may clog the nozzle. Therefore, the nozzle is located on the back of the scraper. That is, when the scraper rotates, the front edge of the scraper pushes and squeezes the raw material, while the back of the scraper does not exert a squeezing force on the raw material. Therefore, it is difficult for the raw material to penetrate into the nozzle, ensuring the unobstructed flow of the nozzle.

[0011] Preferably, the lower surface of the side shaft is also provided with a fixing block and a scraper, and the scraper is rotatably connected to the fixing block by a torsion spring. The fixing block is fixed at the lower surface of the side shaft. The scraper on the lower surface of the side shaft can lift the raw material settled at the bottom of the vessel and push it to the middle of the vessel, so that the raw material is fully mixed. At the same time, spray holes can be opened on the scraper at this position to rinse the bottom of the vessel during cleaning, thereby improving the cleaning effect.

[0012] Preferably, the intermediate shaft is a hollow shaft. Multiple feed holes are opened on the upper outer ring of the intermediate shaft. A hollow second ring is located at each feed hole. The inner ring of the second ring is rotatably and sealed to the intermediate shaft, and multiple discharge ports are opened on the inner ring of the second ring. The discharge ports intermittently connect to the feed holes, and a material pipe is connected to the second ring. Multiple windows are opened at the lower end of the intermediate shaft, and the internal cavity of the intermediate shaft connects to the vessel body through the windows. When liquid raw materials need to be replenished, the raw materials can be replenished through the second ring and the material pipe. The raw materials are injected from the material pipe into the second ring by a material pump, and then injected into the hollow part of the intermediate shaft along the discharge ports and feed holes. Afterwards, the raw materials are discharged from the lower end windows of the intermediate shaft. The raw materials are directly injected into the middle position of the raw materials and are located at the vortex position generated when the raw materials are stirred, which can quickly integrate the replenished raw materials into the previous raw materials and improve the mixing efficiency.

[0013] Preferably, the ring body is provided with a grinding chamber, the surface of which is hollowed out. The lower end of the intermediate shaft is rotatably connected to the grinding chamber, and multiple grinding plates are fixedly connected to the lower end of the intermediate shaft. The grinding plates rotate within the grinding chamber. The liquid raw materials replenished through the material pipe may also contain particulate impurities, some un-crushed sediments, or some flocculent raw materials. After being added to the reactor, these materials cannot be fully mixed with the previous raw materials. Therefore, grinding plates and a grinding chamber are provided. The raw materials added later flow into the grinding chamber, and the intermediate shaft drives the grinding plates to rotate. When the grinding plates sweep across, they press the raw materials against the inner surface of the grinding chamber and rub them. At the same time, the raw materials that can pass through the hollowed-out points on the surface of the grinding chamber are easily mixed with the previous raw materials. The raw materials that cannot pass through continue to be ground and broken in the grinding chamber. This allows the raw materials added later to be fully and evenly mixed with the previous raw materials.

[0014] Preferably, the hollow cavity inside the intermediate shaft is eccentrically arranged from top to bottom; the arrangement of the hollow cavity in the intermediate shaft allows the raw material inside the hollow cavity to be smoothly discharged from the hollow cavity under the action of centrifugal force when the intermediate shaft rotates, instead of being blocked in the hollow cavity. This prevents the raw material from drying and solidifying at the position of the hollow cavity of the intermediate shaft during subsequent heating, which would cause the raw material to become blocked.

[0015] Preferably, each scraper is also provided with a spray hole at its end; spray holes are also provided at both ends of the scraper so that the sprayed water can cover more areas inside the vessel and improve the cleaning effect.

[0016] Preferably, a row of notches is provided at the lower edge of the second plate, and the lower edge of the second plate is chamfered. By providing notches, when the second plate pushes the raw material, the raw material can form a small vortex at the notch, so that the raw material is locally mixed. Then, when the second plate sweeps over again, a large-scale stirring and mixing is carried out, improving the mixing efficiency and effect. Furthermore, the chamfered lower edge of the second plate makes the lower edge of the second plate blade-shaped, which can cut the accumulated raw material or cut and chop some raw material that has been agglomerated into pieces, so as to facilitate subsequent stirring.

[0017] The advantages of this invention are:

[0018] 1. By setting up a central shaft and side shafts, the first and second plates rotate in opposite directions when the raw material is first put into the reactor. This improves the horizontal movement of the raw material and reduces the resistance of the raw material to the first and second plates. In other words, by setting the first and second plates vertically, the raw material is stirred in layers and in opposite directions. With the motor output power remaining unchanged, this dual-shaft bidirectional rotating homogenizer can both agitate the material and protect the motor, allowing it to run in good condition for a long time.

[0019] 2. This invention, by setting a No. 1 ring and spray holes on the scraper, can quickly rinse the vessel body after the raw materials are stirred. The feed pipe is connected to an external water pump, and water is injected into the No. 1 ring and then into the cylinder body along the outlet and feed port. After that, it is diverted into the pipe body and then sprayed out from the spray holes along the pipe body and hose. With the vessel body covered by the lid, the side shaft rotates at the same time, and the water flows out from the spray holes. While rotating, it impacts the inner surface of the vessel body. The water flow directly impacts the inner side wall of the vessel body, resulting in a better rinsing effect and preventing rinsing waste liquid from splashing out and polluting the operating environment.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Example 1:

[0031] Reference Figure 1 andFigure 2 A dual-axis bidirectional rotating homogenizer includes a base 1, a vessel body 2 mounted on one side of the base 1, and a lifting unit on one side of the vessel body 2. The lifting unit includes a base 3, with cylinders symmetrically arranged inside the base 3. A lifting rod 4 is fixedly connected to the output end of each cylinder, and a support plate 5 is fixedly connected to the lifting rod 4. A cover 6 is provided on the upper surface of the support plate 5, and a drive unit is located inside the cover 6. A stirring unit is located inside the vessel body 2, and the stirring unit is connected to the lower surface of the support plate 5 via a vessel cover 7. The cylinders push the lifting rod 4, and the lifting rod 4, through the support plate 5, drives the cover 6 and the vessel cover 7 to move up and down. The agitation unit includes a primary motor 8 and a secondary motor 9; the stirring unit includes an intermediate shaft 10 and a side shaft 11; the lower surface of the support plate 5 is fixed to the vessel lid 7; the intermediate shaft 10 passes through the vessel lid 7 and is fixed to the output end of the primary motor 8 inside the cover 6; the upper outer ring of the intermediate shaft 10 is rotatably connected to a driven gear 12, and the lower outer ring of the intermediate shaft 10 is rotatably connected to a ring body 13; the side shaft 11 is symmetrically fixed between the driven gear 12 and the ring body 13, and the side shaft 11 is symmetrically placed on both sides of the intermediate shaft 10; the driven gear 12 meshes with a driving gear 14, and the driving gear 14 is fixed to the cover 6. The output end of motor 9; multiple inclined plates 15 are fixedly connected to the inner wall of the side shaft 11; multiple inclined plates 16 are fixedly connected to the outer ring of the intermediate shaft 10; in this embodiment of the invention, by designing a dual-axis bidirectional rotation homogenizer, the input raw materials can be quickly and evenly distributed; motor 8 drives the intermediate shaft 10 to rotate counterclockwise, the intermediate shaft 10 drives the plates 16 to rotate, and at the same time, motor 9 drives the side shaft 11 to rotate through the meshing of the driving gear 14 and the driven gear 12, the side shaft 11 drives the plates 15 to rotate. When the second motor 9 drives the side shaft 11 to rotate clockwise, the first plate 15 and the second plate 16 rotate in opposite directions to the raw material that has just been put into the reactor body 2. This can improve the horizontal movement of the raw material and reduce the resistance of the raw material to the first plate 15 and the second plate 16. That is, by setting the first plate 15 and the second plate 16 above and below, the raw material is stirred in layers and stirred in opposite directions. With the motor output power remaining unchanged, this dual-shaft bidirectional rotation homogenizer can not only stir the material, but also protect the motor and keep the motor in good condition for long-term operation.

[0032] Reference Figure 2 and Figure 5A scraping unit is provided on the outer wall of the side shaft 11. The scraping unit includes a scraper 17 and a fixing block 18. The two ends of the scraper 17 are rotatably connected to the fixing block 18 by a torsion spring. The fixing block 18 is fixed on the side shaft 11, and the scrapers 17 on the two side shafts 11 are staggered vertically. When the raw materials are stirred, some raw materials adhere to the inner wall of the vessel body 2. If they are not treated in time, they cannot participate in the mixing of the raw materials, resulting in an uneven mixing ratio of stable raw materials. Therefore, a scraping unit is provided on the side shaft 11. The scraper 17 moves along the inner surface of the vessel body 2 with its edge attached to it. While moving, it passes through the raw materials on the inner surface of the vessel body 2, improving the uniformity of the raw material mixing. At the same time, the scraper 17 is staggered vertically, which can take care of more areas on the inner side of the vessel body 2, and the scraping is more thorough.

[0033] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The lower end of the driven tooth 12 is fixedly connected to a hollow cylinder 19. Multiple feed inlets are opened on the outer ring of the cylinder 19. A hollow ring 20 is fitted onto the outer ring of the cylinder 19. The inner ring of the ring 20 is rotatably and sealingly connected to the surface of the cylinder 19, and multiple outlets are opened on the inner ring of the ring 20. The outlets intermittently connect to the feed inlets. A feed pipe 21 is connected to the ring 20. A tube 22 is provided on the outer ring of the cylinder 19. The tube 22 is laid along the inner side of the side shaft 11. Multiple spray holes 23 are opened on the surface of the scraper 17. The spray holes 23 are connected to flexible hoses, which pass through the side shaft 11 and connect to the tube 22. By setting a... The first ring 20 and the spray holes 23 on the scraper 17 can quickly rinse the vessel body 2 after the raw materials are stirred. The feed pipe 21 is connected to an external water pump. Water is injected into the first ring 20 and then into the cylinder 19 along the outlet and feed port. After that, it is diverted into the pipe 22 and then sprayed out from the spray holes 23 along the pipe 22 and the hose. With the vessel body 2 covered by the lid 7, the side shaft 11 rotates at the same time, and the water flows out from the spray holes 23. While rotating, it impacts the inner surface of the vessel body 2. The water flow directly impacts the inner wall of the vessel body 2, resulting in a better rinsing effect and no rinsing waste liquid splashing out and polluting the operating environment.

[0034] Reference Figure 2 The nozzle 23 is located on the back of the scraper 17. As the scraper 17 rotates, it passes through the raw material on the inner surface of the vessel body 2. At the same time, viscous raw material or raw material with particles may block the nozzle 23. Therefore, the nozzle 23 is located on the back of the scraper 17. That is, when the scraper 17 rotates, the front edge of the scraper 17 pushes and squeezes the raw material, while the back of the scraper 17 does not exert a squeezing force on the raw material. Therefore, it is difficult for the raw material to penetrate into the nozzle 23, ensuring the unobstructed flow of the nozzle 23.

[0035] Reference Figure 2The lower surface of the side shaft 11 is also provided with a fixing block 18 and a scraper 17, and the scraper 17 is rotatably connected to the fixing block 18 by a torsion spring. The fixing block 18 is fixed to the lower surface of the side shaft 11. The scraper 17 on the lower surface of the side shaft 11 can lift the raw material settled at the bottom of the vessel 2 and push it to the middle position of the vessel 2 so that the raw material is fully mixed. At the same time, a spray hole 23 can be opened on the scraper 17 at this position to rinse the bottom position of the vessel 2 during cleaning, thereby improving the cleaning effect.

[0036] Reference Figure 4 and Figure 6 The intermediate shaft 10 is a hollow shaft. Multiple feed holes are opened on the outer ring of the upper end of the intermediate shaft 10. A hollow second ring 24 is located at the position of each feed hole. The inner ring of the second ring 24 is rotatably and sealed to the intermediate shaft 10, and multiple discharge ports are opened on the inner ring of the second ring 24. The discharge ports intermittently connect to the feed holes. A material pipe 241 is connected to the second ring 24. Multiple windows 25 are opened at the lower end of the intermediate shaft 10. The internal cavity of the intermediate shaft 10 connects to the vessel body 2 through the windows 25. When liquid raw materials need to be replenished, they can be replenished through the second ring 24 and the material pipe 241. The raw materials are injected from the material pipe 241 into the second ring 24 by a material pump. Then, the raw materials are injected into the hollow part of the intermediate shaft 10 along the discharge ports and feed holes. Afterward, the raw materials are discharged from the lower end windows 25 of the intermediate shaft 10. The raw materials are directly injected into the middle position of the raw materials and are located at the vortex position generated when the raw materials are stirred, which can quickly integrate the replenished raw materials into the previous raw materials and improve mixing efficiency.

[0037] Reference Figure 4 and Figure 6 The ring body 13 is provided with a grinding chamber 26. The surface of the grinding chamber 26 is hollow. The lower end of the intermediate shaft 10 is rotatably connected to the grinding chamber 26, and multiple grinding plates 27 are fixed to the lower end of the intermediate shaft 10. The grinding plates 27 rotate in the grinding chamber 26. The liquid raw materials supplemented through the material pipe 241 may also contain particulate impurities, some un-crushed sediments, or some flocculent raw materials. After being put into the reactor body 2, they cannot be fully mixed with the previous raw materials. Therefore, the grinding plates 27 and the grinding chamber 26 are set up. The raw materials added later flow into the grinding chamber 26. At the same time, the intermediate shaft 10 drives the grinding plates 27 to rotate. When the grinding plates 27 sweep, they press the raw materials onto the inner surface of the grinding chamber 26 and rub them. At the same time, the raw materials that can pass through the hollow points on the surface of the grinding chamber 26 are easy to mix with the previous raw materials. The raw materials that cannot pass through continue to be ground and broken in the grinding chamber 26. This allows the raw materials added later to be fully and evenly mixed with the previous raw materials.

[0038] Reference Figure 7The hollow cavity inside the intermediate shaft 10 is eccentrically arranged from top to bottom. When the intermediate shaft 10 rotates, the raw material inside the hollow cavity is subjected to centrifugal force and can be smoothly discharged from the hollow cavity instead of being blocked in the hollow cavity. This prevents the raw material from drying and solidifying in the hollow cavity of the intermediate shaft 10 during later heating, which would cause blockage.

[0039] Reference Figure 2 Each scraper 17 is also provided with a spray hole 23 at its end; spray holes 23 are also provided at both ends of the scraper 17 so that the sprayed water can cover more areas inside the vessel body 2 and improve the cleaning effect.

[0040] Example 2:

[0041] Reference Figure 8 Compared with Embodiment 1, as another embodiment of the present invention, the lower edge of the second plate 16 is provided with a row of notches 28, and the lower edge of the second plate 16 is chamfered. By setting the notches 28, when the second plate 16 pushes the raw material, the raw material can form a small vortex at the notch 28, so that the raw material is locally mixed. Then, when the second plate 16 sweeps over again, a large-scale stirring and mixing is carried out, improving the mixing efficiency and effect. Furthermore, the lower edge of the second plate 16 is chamfered, so that the lower edge of the second plate 16 is blade-shaped, which can cut the accumulated raw material, or cut and chop some raw material that has been agglomerated into pieces, so as to facilitate subsequent stirring.

[0042] Working Principle: By designing a dual-shaft bidirectional rotation homogenizer, the input raw materials can be quickly and evenly dispersed. Motor 8 drives the intermediate shaft 10 to rotate counterclockwise, and the intermediate shaft 10 drives the second plate 16 to rotate. At the same time, motor 9 drives the side shaft 11 to rotate through the meshing of the active gear 14 and the driven gear 12. The side shaft 11 drives the first plate 15 to rotate, and motor 9 drives the side shaft 11 to rotate clockwise. For the raw materials that have just been put into the reactor body 2, the first plate 15 and the second plate 16 rotate in opposite directions, which can improve the horizontal movement effect of the raw materials and reduce the resistance of the raw materials to the first plate 15 and the second plate 16. That is, by setting the first plate 15 and the second plate 16 above and below, the raw materials are layered and stirred in opposite directions. With the motor output power remaining unchanged, this dual-shaft bidirectional rotation homogenizer can not only achieve the stirring of materials, but also protect the motor and keep the motor in good condition for long-term operation.

[0043] When the raw materials are stirred, some of them adhere to the inner wall of the vessel 2. If they are not treated in time, they cannot participate in the mixing of the raw materials, resulting in an uneven mixing ratio of the stable raw materials. To address this, a scraping unit is installed on the side shaft 11. The scraper 17 moves along the inner surface of the vessel 2 with its edge attached to it. As it moves, it removes the raw materials from the inner surface of the vessel 2, improving the uniformity of the mixing. At the same time, the scrapers 17 are staggered, which can take care of more areas on the inner side of the vessel 2 and scrape more thoroughly.

[0044] By setting a first ring 20 and spray holes 23 on scraper 17, the vessel body 2 can be quickly rinsed after the raw materials are stirred. The feed pipe 21 is connected to an external water pump. Water is injected into the first ring 20 and then into the cylinder 19 along the outlet and feed port. After that, it is diverted into the pipe 22 and then sprayed out from the spray holes 23 along the pipe 22 and hose. With the vessel body 2 covered by the lid 7, the side shaft 11 rotates at the same time, and the water flows out from the spray holes 23. While rotating, it impacts the inner surface of the vessel body 2. The water flow directly impacts the inner wall of the vessel body 2, resulting in a better rinsing effect and no rinsing waste liquid splashing out and polluting the operating environment.

[0045] As the scraper 17 rotates, it passes through the raw material on the inner surface of the vessel body 2. At the same time, viscous raw material or raw material with particles may clog the nozzle 23. Therefore, the nozzle 23 is set on the back of the scraper 17. That is, when the scraper 17 rotates, the front edge of the scraper 17 pushes and squeezes the raw material, while the back of the scraper 17 does not exert a squeezing force on the raw material. Therefore, it is difficult for the raw material to penetrate into the nozzle 23, ensuring the unobstructed flow of the nozzle 23.

[0046] A scraper 17 is provided on the lower surface of the side shaft 11, which can lift the raw material settled at the bottom of the vessel 2 and push it to the middle position of the vessel 2, so that the raw material is fully mixed. At the same time, a spray hole 23 can be opened on the scraper 17 at this position to rinse the bottom position of the vessel 2 during cleaning, thereby improving the cleaning effect.

[0047] When liquid raw materials need to be replenished, they can be replenished through the second ring 24 and the material pipe 241. The raw materials are injected from the material pipe 241 into the second ring 24 by the material pump. Then the raw materials are injected into the hollow part inside the intermediate shaft 10 along the discharge port and the feed hole. After that, the raw materials are discharged from the lower end window 25 of the intermediate shaft 10. The raw materials are directly injected into the middle position of the raw materials and are located at the vortex position generated when the raw materials are stirred. This can quickly integrate the replenished raw materials into the previous raw materials and improve the mixing efficiency.

[0048] The liquid raw materials replenished through the material pipe 241 may also contain particulate impurities, some un-crushed sediments, or some flocculent raw materials. After being put into the vessel 2, they cannot be fully mixed with the previous raw materials. Therefore, a grinding plate 27 and a grinding chamber 26 are set up. The raw materials added later flow into the grinding chamber 26. At the same time, the intermediate shaft 10 drives the grinding plate 27 to rotate. When the grinding plate 27 sweeps, it presses the raw materials onto the inner surface of the grinding chamber 26 and rubs them. At the same time, the raw materials that can pass through the perforated points on the surface of the grinding chamber 26 can be easily mixed with the previous raw materials. The raw materials that cannot pass through continue to be ground and crushed in the grinding chamber 26. This allows the raw materials added later to be fully and evenly mixed with the previous raw materials.

[0049] The hollow cavity of the intermediate shaft 10 allows the raw materials inside to be smoothly discharged from the cavity due to centrifugal force when the intermediate shaft 10 rotates, instead of remaining blocked inside. This prevents the raw materials from drying and solidifying in the hollow cavity of the intermediate shaft 10 during later heating, thus avoiding blockage. Spray holes 23 are also provided at both ends of the scraper 17, allowing the sprayed water to cover more areas inside the vessel body 2, improving the cleaning effect.
