Description

Technical Field

[0001] This utility model relates to the field of cyclone separation equipment, and in particular to a bamboo cyclone screening device. Background Technology

[0002] Cyclone separators are commonly used to separate dust from the air. In the field of material screening, cyclone separators are also used to screen coarse and fine materials. The screened fine materials are discharged, while the coarse materials are recycled to the crushing equipment for further crushing. However, existing cyclone separators for screening bamboo materials only have a flexible hose at the discharge port of the coarse material circulation. To ensure the stable and effective operation of the cyclone separator, the outlet of this hose cannot be opened for a long time. This ensures that the air intake of the cyclone can only come from the feed end of the crushing equipment to carry the material into the cyclone separator. When a large volume of material accumulates, the hose needs to be opened manually to discharge the material into the feed end of the crushing equipment. Therefore, the operation requires intermittent manual opening and closing of the hose to feed the material, which is cumbersome and has a low degree of automation. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a bamboo cyclone screening device that can automatically and periodically discharge recycled bamboo material while crushing coarse bamboo material, without the need for manual operation.

[0004] To solve the existing technical problems, the technical solution of this utility model is as follows: A bamboo cyclone screening device includes a screening cylinder arranged longitudinally on a support. The discharge port at the lower end of the screening cylinder is inclined downward to one side. A suction component is fixed at the top opening of the screening cylinder, and the air inlet of the suction component is directly facing the inner cavity of the screening cylinder.

[0005] A central feed pipe is fixed at the center of the lower end of the screening cylinder, penetrating the screening cylinder. The upper end of the central feed pipe extends into the inner cavity of the screening cylinder, and the lower end of the central feed pipe is connected to the discharge end of the crusher. An airflow assembly that generates vortices inside the screening cylinder is installed on the side wall of the screening cylinder.

[0006] The screening cylinder is equipped with a material distribution component at its discharge port, and the discharge port is directly opposite the feed end of the crusher.

[0007] Preferably, the suction assembly is a vortex fan fixed at the top opening of the screening cylinder, with the air inlet of the vortex fan facing the inner cavity of the screening cylinder.

[0010] Preferably, the material distribution assembly includes a horizontally positioned material distribution cylinder fixed to the discharge port end of the screening cylinder, the discharge port being connected to the inner cavity of the material distribution cylinder, and a discharge port being formed at the center of the lower part of the material distribution cylinder, which is directly opposite to the discharge port.

[0011] The inner wall of the distributing cylinder is rotatably mounted with a roller, and the outer wall of the roller has four material troughs arranged in a ring array in the middle, with one material trough always facing the discharge port and the other material trough always facing the outlet.

[0012] A transmission assembly is connected between the distributing cylinder and the crushing roller of the crusher. The transmission assembly is used to drive the roller to rotate when the crusher is working.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figures 1 to 6 This embodiment provides a bamboo cyclone screening device, including a screening cylinder 2 arranged longitudinally on a support 1. The screening cylinder 2 is arranged with a diameter that gradually decreases from top to bottom. The discharge port 201 at the lower end of the screening cylinder 2 is arranged to extend downwards to one side. A vortex fan 3 is fixed at the top opening of the screening cylinder 2, and the air inlet of the vortex fan 3 is facing the inner cavity of the screening cylinder 2.

[0029] A central feed pipe 4 is fixed at the center of the lower end of the screening cylinder 2, penetrating the screening cylinder 2. The upper end of the central feed pipe 4 extends into the inner cavity of the screening cylinder 2. The lower end of the central feed pipe 4 is connected to two guide pipes 5. The lower ends of the two guide pipes 5 are connected to the discharge end of the crusher 6. Several air inlet pipes 7 are arranged in a ring array on the side wall of the screening cylinder 2, and the height of the air inlet pipes 7 is higher than the top surface height of the central feed pipe 4.

[0030] Bamboo material is fed into the feed end of the crusher 6. The material is crushed by the rotation of the crushing roller 61 inside the crusher 6. At the same time, the vortex blower 3 works, which creates a negative pressure inside the screening cylinder 2, causing the crushed material to be lifted and enter the central feed pipe 4 through the guide pipe 5, and then enter the screening cylinder 2. At the same time, air is simultaneously introduced into the screening cylinder 2 through multiple air inlet pipes 7, which generates a vortex inside the screening cylinder 2. This causes the material to adhere to the inner wall of the distribution cylinder and rise in a spiral vortex shape. The fine material is sucked by the vortex blower 3 and discharged from the outlet of the vortex blower 3, while the larger bamboo material falls to the discharge port 201 at the lower end of the screening cylinder 2.

[0031] A material distribution component is installed at the discharge port 201 of the screening cylinder 2, and the discharge port 201 is directly opposite the feed end of the crusher 6. The material distribution component includes a horizontally placed material distribution cylinder 8 fixed at the end of the discharge port 201 of the screening cylinder 2. The discharge port 201 is connected to the inner cavity of the material distribution cylinder 8. A discharge port 9 is formed at the center of the lower part of the material distribution cylinder 8, which is directly opposite to the discharge port 201.

[0032] The inner wall of the distributing cylinder 8 is rotatably mounted with a roller 10. The outer wall of the roller 10 has four material troughs 11 arranged in a ring array in the middle, and there is always one material trough 11 facing the discharge port 9 and one material trough 11 facing the discharge port 201.

[0033] Larger bamboo pieces fall into the discharge port 201 of the screening cylinder 2, and then fall into a trough 11. By driving the drum 10 to rotate, the material follows the rotation of the trough 11 and falls into the feed end of the crusher 6 through the discharge port 9 below, thus achieving the effect of large-volume bamboo material recycling and crushing.

[0034] Furthermore, it achieves the effect of automatic feeding of large-volume bamboo materials for recycling. During the feeding process, the discharge port 201 of the sieve and drum 2 is always in a closed state.

[0035] The roller 10 includes a connecting shaft 12 formed in its middle. The two ends of the connecting shaft 12 are rotatably connected to the two ends of the distributing cylinder 8 through bearings. Grooved wheels 13 are symmetrically fixed at both ends of the connecting shaft 12. Rotating shafts 14 are symmetrically rotatably connected to the outer wall of the lower end of the support 1 through bearings. The two rotating shafts 14 are located directly below the two grooved wheels 13. A drive wheel 15 is fixed at one end of the rotating shaft 14 near the grooved wheel 13. The two drive wheels 15 cooperate with the two grooved wheels 13 respectively.

[0036] Synchronous pulleys 16 are fixed at both ends of the rotating shaft 14 and both ends of the crushing roller 61, and a synchronous belt 17 is connected between the two synchronous pulleys 16 on the same side for transmission.

[0037] While the crushing roller 61 rotates, it drives the synchronous belt pulley 16 to rotate, which in turn drives the rotating shaft 14 to rotate, which in turn drives the drive wheel 15 to rotate, which in turn drives the grooved wheel 13 to rotate, which in turn drives the connecting shaft 12 to rotate, thereby causing the drum 10 to rotate. This allows the crushing roller 10 to be driven to feed material while the crushing roller is being crushed. The two synchronous belt pulleys 16 are set to be large and small, which reduces the speed and allows the crushing roller 61 to rotate at high speed, while the drum 10 does not rotate at high speed but rotates intermittently.

[0038] In this way, there is no need to add power equipment for material distribution and unloading, thus reducing the investment in power equipment.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
