Description

Technical Field

[0001] This application relates to the technical field of crushing equipment, and in particular to a high-efficiency material crusher. Background Technology

[0002] A crusher is a machine that crushes large solid raw materials to the required size. It is mainly suitable for material crushing in industries such as food, chemical, pharmaceutical, landscaping, and sanitation.

[0003] The crushers currently in use generally include a crushing chamber, which contains a rotary disc driven by a rotating shaft. The outer circumference of the rotary disc is evenly distributed with cylindrical teeth. These cylindrical teeth are staggered with two rings of short toothed discs mounted on the opposite side of the rotary disc. When the motor drives the rotating shaft to rotate, the cylindrical teeth on the rotary disc and the short toothed discs rotate relative to each other. Due to the centrifugal force, the material entering the crushing chamber is crushed into powder or small particles by the impact between the cylindrical teeth and the short toothed discs.

[0004] Regarding the above-mentioned technology, during the process of crushing particles with cylindrical and short teeth, there is insufficient crushing, resulting in uneven finished particles and affecting the performance of polytetrafluoroethylene powder. Utility Model Content

[0005] In order to fully grind and crush materials, this application provides a high-efficiency material crusher.

[0006] This application provides a high-efficiency material crusher, which adopts the following technical solution:

[0007] A high-efficiency material crusher includes a supporting shell, a drive motor disposed within the supporting shell, a grinding shell disposed above the supporting shell, a receiving shell disposed within the grinding shell, a sealing disc fixedly disposed within the grinding shell, a screen disposed on the sealing disc located within the receiving shell, the inner wall of the screen mesh being shaped like a knife edge, the output shaft of the drive motor passing through the sealing disc, a grinding disc disposed at the end of the drive motor output shaft located within the screen, a plurality of impact pins equally spaced on the grinding disc, a grinding shell cover disposed on the grinding shell, and a receiving shell cover disposed below the grinding shell cover that cooperates with the impact pins of the grinding disc.

[0008] By adopting the above technical solution, material particles are added above the grinding disc, the drive motor is started, the grinding disc rotates, and the impact column and the receiving shell cover work together to crush and grind the material particles. During the rotation of the grinding disc, centrifugal force is generated, causing the material particles on the grinding disc to move towards the screen. The standard powder particles fall into the receiving shell through the screen. When the material particles pass through the mesh, due to inertia, the material particles collide with the inner wall of the screen mesh. The blade-shaped inner wall of the mesh further crushes the material particles, improving the thoroughness of the crushing.

[0009] Optionally, a support is provided inside the support housing, the drive motor is installed inside the support, a motor flange is provided on the top of the support, the drive motor is connected to the support through the motor flange, and the grinding shell is fixedly installed above the motor flange.

[0010] By adopting the above technical solution, the drive motor is fixed by the motor flange.

[0011] Optionally, the bottom of the support is provided with several shock-absorbing pads.

[0012] By adopting the above technical solution, the vibration generated by the drive motor during operation is buffered by the shock-absorbing pad.

[0013] Optionally, the top of the screen is provided with a first connecting ring, and the receiving shell cover is provided with a first connecting groove that cooperates with the first connecting ring.

[0014] By adopting the above technical solution, the screen and the receiving shell cover are connected by the first connecting ring and the first connecting groove, which improves the stability of the screen during operation and the sealing performance of the connection between the receiving shell cover and the screen.

[0015] Optionally, a second connecting ring is provided on the top of the receiving housing, and a second connecting groove is provided on the receiving housing cover to cooperate with the second connecting ring.

[0016] By adopting the above technical solution, the receiving shell and the receiving shell cover are connected by the second connecting ring and the second connecting groove, thereby improving the stability of the connection between the receiving shell and the receiving shell cover.

[0017] Optionally, the receiving housing is provided with a receiving groove.

[0018] By adopting the above technical solution, the material after grinding and crushing falls into the receiving trough, improving the collection of material.

[0019] Optionally, a feeding hopper is connected to the grinding disc shell, and a feeding port that cooperates with the feeding hopper is opened on the receiving shell cover.

[0020] By adopting the above technical solution, material particles can be conveniently poured directly into the grinding disc inside the screen through the feeding hopper.

[0021] Optionally, the grinding disc shell is connected to a connecting shell, and the connecting shell has a connecting channel that communicates with the end of the feeding hopper and the feeding port. The inner diameter of the connecting channel is larger than the inner diameter of the end of the feeding hopper.

[0022] By adopting the above technical solution, the material poured into the feeding hopper falls onto the grinding disc through the connecting pipe. During the rotation of the grinding disc, since the inner diameter of the connecting channel is larger than the inner diameter of the end of the feeding hopper, the crushed material falls onto the inner wall of the connecting channel, reducing the possibility of material flying out of the receiving hopper.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] Add the material particles above the grinding disc, start the drive motor, and the grinding disc will rotate. The impact column and the receiving shell cover work together to crush and grind the material particles. During the rotation of the grinding disc, centrifugal force is generated, which causes the material particles on the grinding disc to move towards the screen. The standard powder particles fall into the receiving shell through the screen. When the material particles pass through the mesh, due to inertia, the material particles collide with the inner wall of the screen mesh. The blade-shaped inner wall of the mesh mesh performs secondary crushing on the material particles, improving the fullness of the crushing of the material.

[0025] The shock-absorbing pads buffer the vibrations generated by the drive motor during operation. Attached Figure Description

Material particles are added above the grinding disc 7, and the drive motor 3 is started. The grinding disc 7 rotates, and the impact column 71 and the receiving shell cover 51 work together to crush and grind the material particles. During the rotation of the grinding disc 7, centrifugal force is generated, causing the material particles on the grinding disc 7 to move towards the screen 6. The standard powder particles pass through the screen 6 and fall into the receiving shell 5. When the material particles pass through the mesh 62, due to inertia, the material particles collide with the inner wall of the mesh 62 of the screen 6. The blade-shaped inner wall of the mesh 62 performs secondary crushing on the material particles, improving the thoroughness of the crushing.

[0032] Reference Figure 2 Several shock-absorbing pads 22 are provided at the bottom of the support 2. The shock-absorbing pads 22 buffer the vibration generated when the drive motor 3 is working.

[0033] Reference Figure 1 and Figure 2 The grinding disc 7 has a feeding hopper 8 connected to its shell, and a feeding port 513 that matches the feeding hopper 8 is provided on the receiving shell cover 51.

The inner diameter of the connecting channel 91 is larger than the inner diameter of the end of the feeding hopper 8. Material poured into the feeding hopper 8 falls onto the grinding disc 7 through the connecting pipe. During the rotation of the grinding disc 7, because the inner diameter of the connecting channel 91 is larger than the inner diameter of the end of the feeding hopper 8, the crushed material falls onto the inner wall of the connecting channel 91, reducing the possibility of material flying out of the receiving hopper.

[0034] Reference Figure 2 The receiving shell 5 is provided with a receiving groove 52. The material after grinding and crushing falls into the receiving groove 52, which improves the collection of material.

[0035] Reference Figure 2A first connecting ring 61 is connected to the top of the screen 6, and a first connecting groove 511 is provided on the receiving shell cover 51 to cooperate with the first connecting ring 61. The screen 6 and the receiving shell cover 51 are connected by the first connecting ring 61 and the first connecting groove 511, which improves the stability of the screen 6 during operation and improves the sealing of the connection between the receiving shell cover 51 and the screen 6. A second connecting ring 53 is connected to the top of the receiving shell 5, and a second connecting groove 512 is provided on the receiving shell cover 51 to cooperate with the second connecting ring 53. The receiving shell 5 and the receiving shell cover 51 are connected by the second connecting ring 53 and the second connecting groove 512, which improves the stability of the connection between the receiving shell 5 and the receiving shell cover 51.

[0036] The implementation principle of a high-efficiency material crusher in this application embodiment is as follows: Material particles are added above the grinding disc 7, the drive motor 3 is started, the grinding disc 7 rotates, the impact column 71 and the receiving shell cover 51 cooperate to crush and grind the material particles. During the rotation of the grinding disc 7, centrifugal force is generated, causing the material particles on the grinding disc 7 to move towards the screen 6. The standard powder particles fall into the receiving shell 5 through the screen 6. When the material particles pass through the mesh 62, due to inertia, the material particles collide with the inner wall of the mesh 62 of the screen 6. The blade-shaped inner wall of the mesh 62 performs secondary crushing on the material particles, improving the fullness of material crushing.
