Description

Technical Field

[0001] The invention relates to the technical field of screening equipment, and in particular to an aluminum particle drum screening device with multi-particle size sorting function and a screening process. Background Art

[0002] Aluminum granules can also be called aluminum shots or aluminum sand. They have a shiny appearance and are mostly cylindrical. They are widely used on the surfaces of aluminum, zinc or thin-walled workpieces. They can also be used to make fireworks. At the same time, aluminum materials made into aluminum granules are more convenient to store, saving a lot of floor space. While reducing oxidation, it also enhances the utilization of aluminum. Due to the advantages of aluminum particles such as high density, easy storage, and no greenhouse gas production during combustion, they are expected to become a solution for replacing fossil fuels in the future.

[0003] However, after aluminum particles are produced, they are usually accompanied by a large amount of dust, debris and other substances, which will inevitably affect the normal production of aluminum particles. At the very least, it will cause a large number of scratches on the surface of the aluminum particles, increasing the rate of oxidation corrosion. At worst, it will cause a large number of already formed aluminum particles to be crushed again, resulting in the aluminum particles being unable to be used normally. In the production process, aluminum particles of different specifications will also be produced. Since the storage method and storage density of each specification of aluminum particles are different, they need to be classified and planned, which requires manual replacement of the screen multiple times. Aluminum powder poses a great threat to human health, so a device is needed to solve the above problems. Summary of the invention

Then the dust suppression box cooperates with the high-pressure fan to generate high pressure to discharge debris, dust and other materials from the screening drum. Then the aluminum particles discharged from the screening drum are fed into the discharge barrel, and then the current change feedback of the discharge component is fed into the secondary stratification chamber. Then the aluminum particles on the secondary stratification chamber will be fed into the discharge barrel, and then with the cooperation of the discharge component, multi-layer information feedback can be performed to control the posture of the stabilizing box.

[0007] A stabilizing track is provided on the support plate, and a stabilizing box is embedded in the stabilizing track and slidably connected to the stabilizing track. A lifting hydraulic rod is provided on the support plate, and the output end of the lifting hydraulic rod is rotatably connected to the stabilizing box. The cylinder body of the lifting hydraulic rod is rotatably connected to the support plate, and the lifting hydraulic rod is electrically connected to the discharge assembly through a wire. A sliding arm is provided on the stabilizing box, and the sliding arm is slidably connected to the support plate. During the screening and stratification process, the posture of the mixture will affect the screening speed and screening, and will also affect the degree of stratification. Therefore, it is very important to adjust the stratification state of the mixture. The posture of the stabilizing box can be adjusted by using the lifting hydraulic rod. Under the support of the sliding arm, the stabilizing box can slide more smoothly, and the stabilizing track will limit the moving trajectory of the stabilizing box.

[0008] The screening cylinder includes a supporting cylinder and a conical cylinder, the supporting cylinder is rotationally connected to a stabilizing box, the conical cylinder is rotationally connected to the supporting cylinder, a plurality of filtering holes are arranged on the conical cylinder, a plurality of layered tracks are arranged in the conical cylinder, the supporting cylinder is rotationally connected to the stabilizing box, a plurality of sliding plates and arc columns are arranged in the layered tracks, the arc columns and the sliding plates are in intermittent sliding contact, when screening, the conical cylinder will swing in the supporting cylinder, while swinging, the arc columns in the layered tracks will slide in the layered tracks, and drive the sliding plates to rotate, thereby hitting the aluminum particles that are bonded into blocks in the conical cylinder, which can reduce the layering error and avoid the problem of blockage, and the setting of the sliding plates will not cause great damage to the formed aluminum particles.

The end of the swing groove away from the transmission rod is rotatably connected to the conical cylinder. The swing arm has a composite telescopic structure. While swing screening is being performed, the stable motor will drive the swing gear to rotate, and the swing gear will drive the transmission gear to rotate. After the transmission gear rotates, the transmission gear will drive the transmission rod to rotate. Utilizing the transmission of the transmission rod, the transmission rod will drive the swing arm to swing, thereby driving the screening cylinder to rotate. The rotating screening cylinder will filter out aluminum particles, so that the layered aluminum particles can be discharged from the filter holes of different particle sizes on the screening cylinder respectively.

[0010] A plurality of filter holes are provided on the support cylinder, and the position of each filter hole corresponds to the filter hole on the conical cylinder.

[0011] The discharging assembly includes a lifting plate and a lifting spring. The lifting plate is slidably connected to the discharging barrel. Both ends of the lifting spring respectively resist the lifting plate discharging barrel. A plurality of sliding switches are arranged in the discharging barrel. A trigger sheet is arranged at the bottom of the lifting plate. The moving track of the trigger sheet is in the same straight line as the installation position of the sliding switch. Each sliding switch is electrically connected to the selection cylinder and the lifting hydraulic rod through a wire. During discharging and the preliminary discharging process, the lifting plate will receive the discharged aluminum particles. Under the action of gravity, the lifting plate will slide in the discharging barrel and drive the trigger sheet to slide on the sliding switch, thereby triggering the sliding switches at different stages and sending out different power signals. When the trigger frequency is too high, it proves that the discharging speed is too fast or the weight of the discharged aluminum particles is large. At this time, it is necessary to adjust the lifting hydraulic rod to raise the stabilizing box. At this time, the discharging speed will decrease and be fully stratified. Then, wait for the discharging speed to decrease before performing the height lowering operation.

The shaking of the screening plate will make the aluminum particles shake fully, thereby achieving the effect of shaking screening, thereby picking out aluminum particles of different particle sizes.
