Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 This utility model provides a technical solution: a centrifuge for raw pharmaceutical materials, including a centrifuge body 1, a buffer plate 2 provided on the outer wall of the centrifuge body 1, a buffer assembly 3 provided at the bottom of the centrifuge body 1, and a sealing mechanism 4 provided inside the centrifuge body 1;
[0025] The sealing mechanism 4 includes a first fixing plate 41, a first sealing plate 42, bolts 43, a limiting plate 44, a second sealing plate 45, a sealing ring 46, and a second fixing plate 47. The centrifuge body 1 has a first fixing plate 41 inside, a first sealing plate 42 installed inside the first fixing plate 41, bolts 43 installed on the outer wall of the first sealing plate 42, a limiting plate 44 installed on the outer wall of the first sealing plate 42, a second sealing plate 45 installed on the outer wall of the limiting plate 44, a sealing ring 46 installed on the outer wall of the second sealing plate 45, and a second fixing plate 47 installed on the inner wall of the second sealing plate 45.

During processing, the internal structure of the centrifuge can be effectively protected, reducing the impact of vibration and impact caused by high-speed rotation on the equipment, thereby extending the service life of the equipment. First, the inner wall of the first fixed plate 41 is fitted with the first sealing plate 42 and fixed with bolts 43. Then, the outer wall of the first sealing plate 42 is fitted with a limit plate 44. The outer walls of the first fixed plate 41, the first sealing plate 42, the second sealing plate 45 and the second fixed plate 47 are provided with sealing rings 46. The inner wall of the second sealing plate 45 is fitted with the second fixed plate 47, and the outer wall of the second fixed plate 47 is fitted with sealing rings 46. Through this structural design, the sealing mechanism 4 can ensure that the raw materials inside the centrifuge will not leak during the operation of the centrifuge, while protecting the inside of the centrifuge from external contamination, ensuring the cleanliness and safety of the centrifugation process.
[0026] Furthermore, a motor 6 is installed on the upper wall of the damping shock absorber 3, and the outer wall of the first fixing plate 41 is tightly fitted with the inner wall of the second sealing plate 45. Through the installation of the damping shock absorber 3, the impact force generated by high-speed rotation can be absorbed and dispersed when the centrifuge is centrifuged, thereby reducing damage to the submerged roller and improving the quality of the rolled product.
[0027] Furthermore, the cleaning component 5 includes a water pump 51, an output pipe 52, an input pipe 53, and a water outlet 54. The water pump 51 is installed on the outside of the centrifuge body 1. One end of the water pump 51 is connected to the output pipe 52, and the other end is connected to the input pipe 53. The water outlet 54 is opened on the outer wall of the centrifuge body 1. With the arrangement of the water pump 51, the output pipe 52, the input pipe 53, and the water outlet 54, when it is necessary to clean the centrifuge body 1, the water pump 51 is first started to connect to the external water source through the input pipe 53, and then clean water is delivered to the centrifuge body 1 through the output pipe 52. Finally, the cleaned water is discharged through the water outlet 54, thus cleaning the inside of the centrifuge. The use of the water pump 51 improves the cleaning efficiency and reduces the time and labor intensity required for manual cleaning.
[0028] Furthermore, multiple bolts 43 are provided, and multiple bolts 43 are fixed to the outer wall of the limiting plate 44 respectively. Through the setting of bolts 43 and the multi-point fixing method, the stability of the sealing mechanism 4 is enhanced, so that the sealing mechanism 4 can maintain a good working condition when facing the vibration and impact force generated when the centrifuge is running at high speed, and avoids the problem of sealing failure caused by vibration.
[0029] Furthermore, multiple sealing rings 46 are provided, and the multiple sealing rings 46 are respectively installed on the outer walls of the first fixed plate 41, the first sealing plate 42, the second sealing plate 45, and the second fixed plate 47.

[0030] Furthermore, the outer wall of the sealing ring 46 is tightly fitted with the outer walls of the second sealing plate 45 and the second fixing plate 47. The setting of the second sealing plate 45 ensures that the centrifuge can be tightly sealed when subjected to impact, thereby protecting the centrifuge body 1 from the influence of the flowing water.
[0031] Furthermore, one end of the water pump 51 is equipped with an output pipe 52, and the other end of the water pump 51 is equipped with an input pipe 53. Through the configuration of the water pump 51, continuous water supply and drainage to the inside of the centrifuge can be achieved, ensuring the continuity and efficiency of the cleaning process.
[0032] Working principle: When the centrifuge processes the raw material, it can effectively protect the internal structure of the centrifuge and reduce the impact of vibration and impact caused by high-speed rotation on the equipment, thereby extending the service life of the equipment. First, the first sealing plate 42 is installed on the inner wall of the first fixed plate 41 and fixed by bolts 43. Then, the limit plate 44 is installed on the outer wall of the first sealing plate 42. Sealing rings 46 are provided on the outer walls of the first fixed plate 41, the first sealing plate 42, the second sealing plate 45, and the second fixed plate 47. The second fixed plate 47 is installed on the inner wall of the second sealing plate 45. A sealing ring 46 is fitted onto the outer wall of the second fixed plate 47. This structural design ensures that the internal raw materials do not leak during centrifuge operation, while protecting the centrifuge interior from external contamination, thus guaranteeing the cleanliness and safety of the centrifugation process. The damping shock absorber 3 absorbs and disperses the impact force generated by high-speed rotation during centrifugation, reducing damage to the submerged rollers and improving the quality of the rolled products. When cleaning the centrifuge body 1 is required, the water pump 51 is first started, and an external water source is connected through the input pipe 53. Then, clean water is delivered to the centrifuge body 1 through the output pipe 52, and finally the cleaned water is discharged from the outlet 54, thus cleaning the inside of the centrifuge. The use of water pump 51 improves cleaning efficiency and reduces the time and labor intensity required for manual cleaning. The setting of sealing ring 46 ensures the sealing performance inside the centrifuge, prevents liquid leakage, and improves the safety and reliability of the equipment. In addition, the multi-point fixing method of bolt 43 enhances the stability of sealing mechanism 4, so that sealing mechanism 4 can maintain a good working condition when facing the vibration and impact force generated when the centrifuge is running at high speed, avoiding the problem of sealing failure caused by vibration. Through the setting of damping shock absorber 3, an elastic support structure is formed between buffer plate 2 and damping shock absorber 3, which can effectively absorb and alleviate the vibration and impact force generated by the centrifuge during high-speed rotation. Through the setting of buffer plate 2, it is ensured that the buffer plate 2 can evenly distribute the force when subjected to impact, thereby protecting the centrifuge body 1 from the influence of uneven force. Through the setting of water pump 51, continuous water supply and drainage inside the centrifuge can be realized, ensuring the continuity and efficiency of the cleaning process.
