Description

Technical Field

[0001] The utility model relates to a pipe crushing mechanism, belonging to the technical field of crushers. Background Art

[0002] In modern industrial production, pipes, as a common material, are widely used in various fields. With the development of production and the need for replacement, the number of waste pipes is increasing day by day. How to effectively recycle and reuse these waste pipes has become an important issue in environmental protection and resource recycling. Traditional pipe treatment methods include crushing, incineration, etc. Although existing crushing equipment can effectively crush pipes, it cannot effectively separate the metal substances in the waste pipes during the crushing process, resulting in low recycling efficiency. After retrieval, it is found that the Chinese patent with the publication number CN218139249U discloses a shredder with a filtering and screening function. In this patent, the driving motor drives the conveyor belt to drive the rotating roller to rotate. The operator puts the material to be crushed into the feeding hopper, and the material falls into the crushing box by gravity. Inside the crushing box, the crushing knives and auxiliary knives on the rotating roller shear and tear the material. The crushed material is screened by the filter plate. The qualified material falls into the discharge hopper through the filter plate and is discharged through the discharge chute. The larger material that does not pass through the filter plate remains in the discharge hopper and waits for the next round of crushing and screening. However, when tearing and crushing waste plastic pipes, this patent cannot screen the metal carried on the waste plastic pipes, and the plastic crushed material and the metal crushed material are mixed together, which is not conducive to subsequent recycling.

The magnetic screen 213 is arranged between the blanking port 122 and the material distributing channel 211. The magnetic screen 213 is adapted to adsorb metal impurities in the crushed materials;

[0032] The crushed materials after crushing treatment are adapted to enter the material distributing channel 211 from the blanking port 122 and be discharged through the discharging port 212.

[0033] Specifically, as shown Figure 3-5 in the figure, the crushing component includes a first crushing roller 31 and a second crushing roller 32. The first crushing roller 31 and the second crushing roller 32 are both rotatably installed in the crushing cavity 123. The first crushing roller 31 and the second crushing roller 32 are arranged oppositely. A crushing channel is arranged between the first crushing roller 31 and the second crushing roller 32.

[0034] Specifically, the crushing component further includes a driving mechanism. The driving mechanism can specifically be the following structure, including a driving motor, a main transmission gear and a slave transmission gear. The driving motor is installed on the outer shell of the crusher 12. The main transmission gear is connected to the first crushing roller 31. The movable end of the driving motor is connected to the main transmission gear. The slave transmission gear is connected to the second crushing roller 32. The main transmission gear is meshed with the slave transmission gear. The driving motor is adapted to drive the main transmission gear to rotate to drive the slave transmission gear to rotate, so that the first crushing roller 31 and the second crushing roller 32 rotate relatively.

[0035] In this embodiment, the driving motor drives the main transmission gear to rotate clockwise. The main transmission gear is connected to the first crushing roller 31. Therefore, the first crushing roller 31 also rotates clockwise. Since the main transmission gear is meshed with the slave transmission gear, the slave transmission gear rotates counterclockwise and drives the second crushing roller 32 to rotate counterclockwise. Crushing blades are installed on both the first crushing roller 31 and the second crushing roller 32, which are used to tear and crush the pipes. The waste pipes are crushed into small sections when passing through the crushing channel.

[0036] Specifically, as Figure 6 shown, the material distribution channel 211 is provided with an inclined surface 211A having a certain inclination angle.

[0037] Specifically, as Figure 7 shown, at least one guide plate 211B is provided in the material distribution channel 211, and the guide plate 211B is adapted to guide the sieved crushed material to the discharge port 212.

[0038] Specifically, as Figure 6 shown, a guide plate 212A adapted to guide the discharge of the crushed material is provided at the discharge port 212.

[0039] In this embodiment, the inclined surface 211A is provided to ensure that the crushed material can smoothly slide downward along the inclined surface under the action of gravity, so as to effectively move from the material distribution channel 211 to the discharge port 212, increasing the fluidity of the crushed material;

[0040] The guide plate 211B is provided to further guide and control the flow direction of the crushed material, so that the crushed material can be accurately guided to the discharge port 212.

[0041] Specifically, as Figure 6 shown, the magnetic screen 213 is installed on the material distribution rack 21 through two fastening screws 4.

[0042] In this embodiment, the material distribution rack 21 is provided with a mounting seat, and the mounting seat is provided with two threaded holes adapted to the fastening screws 4.

Align the through holes on the magnetic screen 213 with the threaded holes on the mounting seat, and tighten the fastening screws 4 to firmly fix the magnetic screen 213 on the mounting seat. After the waste pipe is crushed and collected, the magnetic screen 213 can be disassembled by loosening the fastening screws 4 for cleaning, so as to keep the magnetic screen 213 clean.

[0043] Specifically, as Figure 1-2 shown, the screening support 2 is provided with four support feet 5, and shock-absorbing springs are provided on the support feet 5. The shock-absorbing springs are adapted to buffer the vibration generated on the screening support 2 when the crushed material falls onto the magnetic screen 213.

[0044] Shock-absorbing springs are installed on the support feet 5. These shock-absorbing springs can absorb part of the vibration energy generated when the crushed material falls onto the magnetic screen 213, reduce the impact of the equipment on the ground, and thus reduce the impact of the noise and vibration generated during the operation of the equipment on the surrounding environment.

[0045] In this embodiment, the waste pipe to be crushed is fed into the crusher 12 through the feeding port 121 by an external conveying mechanism. The crushing components in the crusher 12 start to work. The first crushing roller 31 and the second crushing roller 32 rotate relatively. The pipe is clamped between the first crushing roller 31 and the second crushing roller 32 and crushed into small segments. The crushing process is carried out in the crushing channel. The crushed material falls from the blanking port 122 onto the magnetic screen 213 on the material distributing rack 21. Metal impurities are adsorbed by the magnetic screen 213, and the crushed material of the non-metal part (such as plastic debris) falls through the magnetic screen 213 into the material distributing channel 211;

[0046] The crushed material falling into the material distributing channel 211 smoothly slides down to the discharge port 212 through the inclined plane 211A. During this process, the guide plate 211B can guide the crushed material to accurately enter the discharge port 211, and then the guide plate 212A guides the crushed material to smoothly discharge from the discharge port 211 for collection, effectively preventing accumulation and splashing. This pipe crushing mechanism can efficiently and stably process a large number of pipes, and at the same time ensure that the crushed material can be quickly and effectively sorted and discharged, greatly improving the production efficiency and the quality of material recovery.
