Description

Technical Field

[0001] This utility model relates to the field of biopharmaceuticals, and more specifically, to a bio-extraction pulverizer. Background Technology

[0002] A bio-extraction pulverizer is a device used for extracting and pulverizing biological materials. It typically consists of a pulverizing chamber, pulverizing blades, a screen, and a motor. During the pulverizing process, the material enters the pulverizing chamber through the feed inlet and is pulverized into fine powder by the high-speed rotating hammers. The pulverized fine powder can be screened through the screen; qualified fine powder can be discharged through the discharge outlet, while unqualified coarse powder can be re-entered into the pulverizing chamber for secondary pulverization.

[0003] In order to avoid material accumulation and affect crushing efficiency during the crushing process, and at the same time, it is necessary to ensure that the feed inlet is sealed to prevent material from splashing out. Existing crushers use manual feeding, and the feed inlet needs to be sealed manually, which requires the operator to operate with both hands, which is not convenient.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] The present invention is further configured such that: a rotating part is fixedly connected to the cover plate, a receiving groove for accommodating the rotating part is provided on the cover plate, a rotating column is fixedly connected to both ends of the rotating part, and a rotating hole that cooperates with the rotating column is provided on the groove wall of the receiving groove.

[0008] The present invention is further configured such that: the rotating part is provided with a rotating arc surface, the rotating arc surface is located on the side of the rotating part away from the crushing cylinder, and the receiving groove is fitted to the arc surface of the rotating part.

[0009] The present invention is further configured such that: the cover plate has a plurality of cavities for accommodating torsion springs, the cavities are connected to the rotating holes, one end of the torsion spring abuts against the upper cavity wall of the cavity, and the other end of the torsion spring is engaged with the rotating part.

[0010] The present invention is further configured such that: a snap-fit ​​hole is provided on the rotating part, and a snap-fit ​​part is provided on the torsion spring, and the snap-fit ​​part snaps into the snap-fit ​​hole.

[0011] The present invention is further configured such that: the longitudinal section of the cover plate is trapezoidal, the lower end area of ​​the cover plate is larger than its upper end area, and the edge of the cover plate is attached to the cover plate.

[0012] The present invention is further configured such that the crushing cylinder is made of stainless steel.

[0013] In summary, this utility model has the following beneficial effects:

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Bio-extraction pulverizer, such as Figures 1 to 5As shown, the device includes a crushing cylinder 1, a cover plate 2 detachably connected to the crushing cylinder 1, a feed inlet 3 on the cover plate 2, and a cover plate 4 rotatably connected to the cover plate 2 to close the feed inlet 3. Two torsion springs 11 are provided between the cover plate 2 and the cover plate 4 to drive the cover plate 4 to close. The cover plate 4 is used to close the feed inlet 3, while the cover plate 4 can be opened for feeding. The cover plate 4 is subjected to the force of the torsion springs 11, so that after feeding, the cover plate 4 can be reset to close the feed inlet. The crushing cylinder 1 is made of stainless steel, which gives the crushing cylinder 1 good corrosion resistance and improves its service life.

[0023] like Figure 3 , Figure 4 and Figure 5 As shown, a rotating part 5 is integrally formed on the cover plate 4, and a receiving groove 6 for accommodating the rotating part 5 is provided on the cover plate 2. Rotating columns 7 are fixedly connected to both ends of the rotating part 5. Two rotating holes 8 are provided on the groove wall of the receiving groove 6 to cooperate with the rotating columns 7. By setting the rotating columns 7 to rotate within the rotating holes 8, the rotating part 5 is kept rotating within the receiving groove 6, thereby enabling the cover plate 4 to rotate on the cover plate 2. The rotating part 5 has a rotating arc surface 9, located on the side of the rotating part 5 away from the crushing cylinder 1. The receiving groove 6 fits against the arc surface of the rotating part 5, thus ensuring a tight seal when the rotating part 5 rotates within the receiving groove 6. Two cavities 10 are provided to accommodate the torsion spring 11. The cavities 10 are connected to the rotating hole 8, and the torsion spring 11 is sleeved on the rotating column 7 to provide a limiting effect. One end of the torsion spring 11 abuts against the upper cavity wall of the cavity 10, and the other end of the torsion spring 11 is engaged with the rotating part 5. The torsion spring 11 located in the cavity 10 can abut against the rotating part 5 and the cover plate 2 respectively, so that the cover plate 4 can automatically reset. The rotating part 5 is provided with a snap-fit ​​hole 12, and the torsion spring 11 is provided with a snap-fit ​​part 13. The snap-fit ​​part 13 is perpendicular to one end of the torsion spring 11, so that the snap-fit ​​part 13 can be engaged into the snap-fit ​​hole 12, thereby realizing the snap-fit ​​between the torsion spring 11 and the rotating part 5.

[0024] like Figure 4 and Figure 5 As shown, the longitudinal section of the cover plate 4 is trapezoidal, the area of ​​the lower end of the cover plate 4 is larger than the area of ​​the upper end, and the edge of the cover plate 4 is attached to the cover plate 2, so that the cover plate 4 keeps the feed inlet 3 closed, and the area of ​​the contact surface between the cover plate 4 and the cover plate 2 is larger, which improves the sealing effect.

[0025] Working process: When materials need to be fed, the operator picks up the materials and squeezes the cover plate 4 with the other hand, causing the cover plate 4 to rotate toward the crushing cylinder 1. During this process, the cover plate 4 separates from the cover plate 2. At the same time, the rotating part 5 rotates in the receiving groove 6, and the rotating arc surface 9 slides against the groove wall of the receiving groove 6. The rotating column 7 rotates in the rotating hole 8. Since the snap-fit ​​part 13 on the torsion spring 11 is snapped into the rotating hole 8 of the rotating part 5, the other end of the torsion spring 11 abuts against the cavity wall of the cavity 10, thereby the torsion spring 11 undergoes elastic deformation, and the angle between the two endpoints of the torsion spring 11 becomes smaller. Then, the operator completely stuffs the material into the feed inlet 3 and stops squeezing the material. Then, the operator lifts his hand to stop squeezing the cover plate 4. At this time, the elastic deformation of the torsion spring 11 recovers, and the cover plate 4 rotates under the force of the torsion spring 11 until the cover plate 4 closes the feed inlet 3 again.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
