Description

Technical Field

[0001] This utility model specifically relates to the field of rotary vibrating screen technology, and more specifically to a rotary vibrating screen for the production of biological pellets. Background Technology

[0002] A vibrating screen is a high-precision fine powder screening machine with advantages such as low noise, high efficiency, and convenient screen replacement. It is widely used in chemical, food, metal, and mining industries. The vibrating screen uses a vertical motor as the excitation source, with eccentric weights installed at the upper and lower ends of the motor. This converts the motor's rotational motion into three-dimensional motion (horizontal, vertical, and inclined), which is then transmitted to the screen surface. Adjusting the phase angle at the upper and lower ends can change the trajectory of the material on the screen surface, thereby achieving different screening effects.

[0003] In traditional rotary vibrating screens, when the motor wiring is reversed, although the motor can still rotate the screen, the rotation cannot effectively disperse the material. This causes the material to accumulate on the screen, hindering effective screening and reducing work efficiency. Furthermore, traditional rotary vibrating screens cannot be replaced, meaning they can only screen materials at the same mesh size. Therefore, when changing the material, traditional rotary vibrating screens cannot effectively meet the screening requirements.

[0004] A search revealed that Chinese Patent Publication No. CN201620994535.X discloses a novel rotary vibrating screen; it includes a rotary vibrating screen body, an automatic feeder, a feeding port on the upper part of the rotary vibrating screen body, an output end of the automatic feeder connected to the feeding port of the rotary vibrating screen through a pipe, a discharge port on the side of the rotary vibrating screen body, a filter screen inside the rotary vibrating screen body, a vibrating motor at the lower part of the rotary vibrating screen body, a valve at the discharge port, and a glass cover at the feeding port. The glass cover and the output end pipe of the automatic feeder can precisely seal the feeding port, and a pulse generator is provided on the upper part of the filter screen.

[0005] Although the device in the aforementioned patent can achieve the screening effect, the filter screen in the aforementioned patent cannot be replaced during operation. This results in a screening effect that can only be achieved for materials of the same material and the same mesh size. When the material is changed, the screening effect cannot be effectively met. Furthermore, during the screening process, the powder mixed in the material will fly around, and the device in the aforementioned patent cannot effectively collect the powder generated during screening. Utility Model Content

[0006] The purpose of this invention is to provide a vibrating screen for biomass pellet production. In this device, two vibrating screens are placed on corresponding mounting rings. This allows the vibrating screens to effectively disperse the material to the surrounding area regardless of whether the motor rotates forward or backward, thus ensuring the screening effect. During the screening process, the rotation of the vibrating screens causes the levers to move the material on the screens, thereby improving screening efficiency. The powder generated during screening is collected and processed centrally through a connecting pipe and a negative pressure machine, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A vibrating screen for biomass pellet production includes a base; multiple springs are mounted on the base; the end of each spring away from the base is fitted with the bottom of a second housing; the second housing has an integrally formed second mounting ring and a spherical plate; a second vibrating screen is movably mounted on the second mounting ring; the springs between the base and the second housing effectively ensure that the material bounces up and down during the screening process, thereby effectively ensuring the screening quality.

[0009] The first housing is fixedly installed at the end of the second housing away from the base; a first mounting ring is integrally provided on the inner wall of the first housing; the first mounting ring is movably installed with the first vibrating screen; the vibrating screen fits into the mounting ring, so that when the drive device rotates, the vibrating screen can effectively diffuse the material to the surrounding area regardless of whether it rotates forward or backward.

[0010] As a further technical solution of this utility model, a first lever and a second lever are fixedly installed on the inner walls of the first shell and the second shell respectively; the first lever and the second lever are respectively located above the first vibrating screen and the second vibrating screen; when the vibrating screen spreads the material to the surroundings, the material also contacts the lever inside the shell, thereby realizing the movement of the material, thereby improving the screening effect and efficiency of the vibrating screen.

[0011] As a further technical solution of this utility model, a negative pressure port is provided on the same side wall of the first shell and the second shell to facilitate the installation of the connecting pipe; the connecting pipe is fixedly installed with the negative pressure machine; a cover is provided at the end of the first shell away from the second shell, and a feed port is provided on the cover; the cover effectively blocks the dust generated during screening, avoiding dust from flying; at the same time, the negative pressure machine collects the connecting pipe under negative pressure, realizing the effective collection of dust in the two shells;

[0012] As a further technical solution of this utility model, the bottom of the spherical plate is provided with a mounting plate; the mounting plate is fixedly installed with the driving device.

[0013] As a further technical solution of this utility model, a first discharge port and a second discharge port are respectively fixedly installed on the first shell and the second shell; the first discharge port and the second discharge port are located above the first rotary vibrating screen and the second rotary vibrating screen; the material after screening by the first rotary vibrating screen and the second rotary vibrating screen is transported to the collection device through the corresponding discharge port;

[0014] As a further technical solution of this utility model, the second shell is further provided with a third discharge port; the third discharge port is located on the side wall at the bottom of the second shell; the material screened by the second vibrating screen falls onto the spherical plate, and the material is discharged through the third discharge port through the surface of the spherical plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In use, the material is added to the first vibrating screen inside the first housing through the feed port on the cover. The first vibrating screen is driven by the drive device to rotate along the first mounting ring on the inner wall of the first housing. The first vibrating screen is installed in close contact with the first mounting ring. In this way, no matter whether the drive device rotates forward or backward, the first vibrating screen can spread the material to the surrounding area. When the material is spread to the surrounding area, it also comes into contact with the first lever. By moving the first lever, materials of different sizes can be moved, thereby improving the screening efficiency. The material screened by the first vibrating screen is effectively discharged through the first discharge port.

[0017] 2. In this utility model, the material screened by the first vibrating screen falls onto the second vibrating screen inside the second housing. The second vibrating screen has the same structure as the first vibrating screen, thereby ensuring the screening quality and efficiency of the material. The material screened by the second vibrating screen is effectively discharged through the second discharge port provided on the second housing, thereby realizing the independent collection of materials of different sizes.

[0018] 3. In the screening process of this utility model, the powder or dust generated by the material inside the first shell and the second shell during screening is drawn into the connecting pipe by a negative pressure machine. The two connectors of the connecting pipe extend into the first shell and the second shell, thereby effectively realizing the negative pressure extraction of powder or dust and storing it independently.
