Description

Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to a bidirectional spiral screening machine for decoration waste. Background Art

[0002] The spiral screen uses a screw shaft as its power center. Depending on the configuration, the screw shaft is equipped with several spiral blades. The compact design of the screw shaft makes it ideal for separating sticky and wet materials. The spiral blades have virtually no entanglement points. During operation, hard materials such as rocks and bricks are discharged from the left side, while materials such as slag are screened below, and light materials such as large pieces of plastic are discharged at the end.

[0003] However, in actual operation, this method has drawbacks. When discharging hard materials, some lightweight materials inevitably enter the mix. This problem not only affects the purity of the hard materials but can also adversely affect subsequent processing. For example, in the construction industry, excessive mixing of lightweight materials with hard materials can reduce the quality and performance of the building materials. To effectively address this drawback, a bidirectional spiral screening machine for construction waste is proposed. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-5 The bidirectional spiral screening machine for decoration waste plays an important role in the process of processing decoration waste. The equipment shell 1 is made of strong and durable materials, which can withstand the impact and wear caused by decoration waste.

[0028] Five spiral shafts 2 are installed within the machine, which play a key role in screening during operation. Each spiral shaft 2 is equipped with a positive spiral blade 3, which is designed to effectively move the renovation waste within the machine, achieving preliminary screening. The two non-lateral spiral shafts 2 are equipped with reverse spiral blades 4, which can push the material in the opposite direction under certain circumstances, further improving the accuracy and efficiency of screening.

[0029] A transmission cavity 9 is provided inside the device housing 1, which provides space for power transmission of the device. A device slot 5 is provided on the outer wall of the device housing 1 to facilitate installation and maintenance of internal transmission components.

[0030] A rotating shaft 10 connected to the screw shaft 2 is provided in the transmission chamber 9. The rotating shaft 10 can transmit power to the screw shaft 2 to enable it to operate normally. A transmission shaft 11 extending into the equipment slot 5 is provided in the transmission chamber 9. The transmission shaft 11 is connected to the rotating shaft 10 through a transmission mechanism. The transmission mechanism includes a driving gear 12 mounted on the transmission shaft 11. The driving gear 12 plays a key role in power transmission. A transmission gear 13 meshing with the driving gear 12 is provided on the rotating shaft 10. Both the driving gear 12 and the transmission gear 13 are bevel gears. This design makes the meshing tighter and the transmission more stable. Moreover, the meshing method is vertical meshing, which makes full use of the space inside the equipment and improves the transmission efficiency.

[0031] A drive motor 6 is installed within the equipment slot 5 via a mounting bracket 7. This drive motor 6 provides power for the entire device. The mounting bracket 7 is connected to a drive shaft 11 via a snap-fit ​​mechanism. This snap-fit ​​mechanism includes a snap-fit ​​shaft 14 mounted on the output shaft of the drive motor 6. The end of the drive shaft 11 located within the equipment slot 5 is provided with a snap-fit ​​groove corresponding to the snap-fit ​​shaft 14. Both the snap-fit ​​shaft 14 and the snap-fit ​​groove exhibit a regular hexagonal cross-section, ensuring a secure connection and preventing loosening during operation. The outer wall of the snap-fit ​​shaft 14 and the inner wall of the snap-fit ​​groove are polished to reduce friction and improve transmission efficiency.

[0032] The drive motor 6 is connected to the device housing 1 through a mounting mechanism. The mounting mechanism includes a fixing bolt 8 arranged on the mounting frame 7. The device housing 1 is provided with a fixing groove corresponding to the fixing bolt 8. The fixing bolt 8 can ensure that the drive motor 6 is installed firmly and reliably.

[0033] Two of the driving gears 12 are larger than the other driving gears 12, with a size ratio of 1:1.5. The design of the driving gears 12 of different sizes can make the rotational speed of the two spiral shafts 2 with the counter-spiral blades 4 different from the rotational speed of the other spiral shafts 2.

[0034] The mounting frame 7 is provided with a handle, which is U-shaped to facilitate installation and removal by operators.

[0035] When the utility model is used, the driving motor 6 is started, and the output shaft of the driving motor 6 drives the clamping shaft 14 to rotate. The clamping shaft 14 is tightly combined with the clamping groove at the end of the transmission shaft 11 through a regular hexagonal connection, so that the transmission shaft 11 rotates accordingly. The driving gear 12 on the transmission shaft 11 starts to run. Since the driving gear 12 is engaged with the transmission gear 13 on the rotating shaft 10, and the driving gear 12 and the transmission gear 13 are both bevel gears, the meshing method is vertical meshing, so the rotating shaft 10 is driven to rotate. The five spiral shafts 2 connected to the rotating shaft 10 start to work. The positive spiral blades 3 on each spiral shaft 2 push the decoration waste to move in the equipment housing 1 and perform preliminary classification. The discharge on the left is hard materials such as stones and bricks, the sieve is slag, and the end is large pieces of light plastic.

[0036] The counter-spiral blades 4 on the two non-lateral spiral shafts 2 function in specific situations. When some lightweight material enters the hard material discharge port along with the hard material, these two spiral shafts 2 with counter-spiral blades 4 can reversely recover the majority of the material while simultaneously allowing the hard material to continue to discharge, maintaining normal operation. This results in faster and better classification and cleaner hard material discharge. Furthermore, the relatively high rotational speed of these two spiral shafts 2 allows for faster reverse recovery of the majority of the material.

[0037] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
