Description

Technical Field

[0001] The utility model relates to the technical field of medicine processing, and more specifically, to a raw material mixing device for medicine processing. Background Art

[0002] Medicines can be used to prevent and treat diseases and are important products in medical activities. When making medicines, in order to process medicines rich in a variety of therapeutic substances, it is necessary to mix and stir the raw materials of various medicines. Using a mixing device to mix and stir can improve the mixing efficiency and facilitate subsequent processing.

[0003] Most common raw material mixing devices have a simple structure and only have a mixing and stirring structure. In actual processing, the raw materials involved in the mixing are mostly fine crushed powders. When poured into the mixing equipment, the fine raw materials that are easy to get out will spread to the surroundings, and the smaller particles will become dust floating in the air, failing to enter the mixing equipment in time, but spreading and diffusing at the feed inlet. This phenomenon will also occur when discharging the material, which will not only pollute the surrounding air quality, but also cause a waste of raw materials; moreover, in common mixing devices, the stirring structure is relatively simple, generally only the stirring shaft and the stirring blades cooperate for stirring, and this stirring structure can only stir in a single direction, so that the raw materials move in one direction in the horizontal plane, and the exchange between raw materials at different heights is small, and the mixing effect of the raw materials is limited; in addition, when mixing, some raw materials may adhere to the inner wall of the mixing device and cannot be discharged by themselves, which will not only reduce the collection amount of pharmaceutical raw materials, but also affect the subsequent work of the mixing device.

When discharging, the control valve 29 is operated to make the discharge pipe 3 unobstructed.

[0048] In summary, when the overall equipment is in use (or running):

[0049] When the equipment is used, the electrical equipment is connected to an external power source, and a mixing structure is provided through the tank body 1. When adding materials, the closing cover 28 is opened, and the pharmaceutical raw materials are added from the feed pipe 2 into the tank body 1 for mixing. The feed pipe 2 is surrounded by the first shielding ring 20 to prevent the dust of the raw materials from splashing around. The dust suction pump 7 corresponding to the first dust hood 4 is turned on, and the suction force is provided by the dust suction pump 7 so that the first dust hood 4 sucks the dust raised around the feed pipe 2 and introduces it into the dust collecting box 6. After the loading is completed, the closing cover 28 is closed to block the feed pipe 2, and the control valve 29 is in a closed state during the mixing. When mixing, the drive motor 8 is started, and the drive motor 8 controls the rotation of the stirring shaft 9. The stirring shaft 9 drives the stirring blade 10 to rotate, so as to stir the pharmaceutical raw materials in the tank body 1 in the horizontal direction. When the stirring shaft 9 rotates, the driving gear 13 cooperates with the driven gear 14. Through the transmission of the driving gear 13 and the driven gear 14, the auxiliary shaft 11 rotates, and the peripheral auxiliary shaft 11 drives the spiral blade 12 to rotate, and the raw materials in the lower layer are transported to the upper side for vertical stirring, and cooperate with the stirring blade 10 to provide a more sufficient stirring effect. After the mixing is completed, the control valve 29 is operated to make the discharge pipe 3 unobstructed, and the raw materials are discharged from the discharge pipe 3. During the discharging process, the discharge pipe 3 is surrounded by two shielding rings to prevent the dust of the raw materials from splashing around, so as to facilitate the second dust hood 5 to absorb, so that the dust pump 7 corresponding to the second dust hood 5 works, and the suction provided by the dust pump 7 causes the second dust hood 5 to suck in the dust raised around the discharge pipe 3 and introduce it into the dust collecting box 6.

[0050] When the dust suction pump 7 absorbs dust and gas and guides the gas and dust into the dust collecting box 6, the excess gas will flow out from the vent 22 to ensure the balance of air pressure and allow the gas to flow normally, while the raw dust will be filtered by the dust filter 23 and remain in the dust collecting box 6. The dust collecting box 25 is arranged inside the dust collecting box 6 to collect the falling dust. The dust collecting box 25 is conveniently pulled out from the sliding opening 24 by pulling the plate 26. The dust collecting box 25 can be taken out to process the collected raw dust. When the dust collecting box 25 is loaded into the dust collecting box 6, the dust collecting box 25 is inserted from the sliding opening 24 so that the pulling plate 26 contacts the dust collecting box 6 through the sealing ring 27. The pulling plate 26 is fixed to the dust collecting box 6 by fixing bolts. The pulling plate 26 is tightly attached to the dust collecting box 6 through the sealing ring 27 and remains stable under the fixation of the fixing bolts, so that the dust collecting box 25 can stably accept dust, and the sealing ring 27 ensures air tightness and the collection capacity of the dust collecting box 6.

[0051] In addition, before mixing, the connecting frame 18 is lifted in advance through the cooperation of external equipment and the pulling ring 19, and the connecting frame 18 fixes the multiple moving rods 15 together, so that the multiple moving rods 15 rise, and the moving rods 15 drive the moving ring 16 to rise, and the moving ring 16 drives the cleaning ring 17 to stay in the upper part of the tank body 1. After the mixing is completed, when discharging the material, the connecting frame 18 is lowered, and the moving rods 15 control the moving ring 16 to move, so that the moving rods 15 move along the tank body 1, and the moving ring 16 drives the cleaning ring 17 to move, so that the cleaning ring 17 moves downward along the inner wall of the tank body 1, and the raw materials attached to the tank body 1 are scraped off and cleaned to avoid raw material residue.
