Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aluminum ash screening machines, specifically an aluminum ash screening machine. Background Technology
[0002] The main components of aluminum ash are metallic aluminum, aluminum oxide, and oxides of iron, silicon, and magnesium, as well as chlorides of metals such as potassium, sodium, calcium, and magnesium. Since aluminum ash contains a high content of metallic aluminum, it is necessary to recycle the aluminum. In the recycling process, the aluminum ash needs to be screened using a screening machine. The screening of aluminum ash is to separate the metallic aluminum particles so that the aluminum can be sold and the remaining substances can be dissolved.
[0003] For drum-type screening machines, screening is generally done through a filter screen. After screening, the aluminum metal will remain inside the screen. Due to the structural design of the drum, the metal will generally remain in the lower part, making it difficult to remove the screened aluminum metal. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides an aluminum ash screening machine, which solves the problems mentioned in the background.
[0005] This utility model provides the following technical solution:
[0006] Includes: a screening inner cylinder, a screening outer cylinder installed at one end of the screening inner cylinder, and a screen cylinder side cover installed at the other end of the screening inner cylinder;
[0007] Also includes:
[0008] An airflow guide pipe is horizontally installed in the center of the outer screening cylinder. The airflow guide pipe extends outward through the outer screening cylinder and is connected to a blower compartment.
[0009] Airflow guide holes are formed on the surface of the airflow guide tube, and multiple sets of airflow guide holes are formed along the surface of the airflow guide tube.
[0010] The discharge hopper is located on the surface of the side cover of the screen cylinder. A discharge collection plate is slidably connected in the groove of the discharge hopper. The inner wall of the outer screening cylinder has a groove that fits the front end of the discharge collection plate. A cover plate connected to the side cover of the screen cylinder is provided at the opening of the discharge hopper.
[0011] Furthermore, the cover plate is connected to the side cover of the screen cylinder by a rotating shaft, and an annular slider is fixed on the opposite side of the outer screening cylinder and the side cover of the screen cylinder. Support rings adapted to the annular slider are opened at both ends of the inner screening cylinder.
[0012] Furthermore, a guide plate is provided on the surface of the outer screening cylinder, and one end of the guide plate extends outward through the outer screening cylinder and is connected to a guide hopper.
[0013] Furthermore, the internal channel of the guide plate is inclined, and the front end of the guide plate extends to the center of the screening inner cylinder.
[0014] Furthermore, a discharge collection pipe is installed in the center of the side cover of the screen cylinder. One end of the discharge collection pipe extends into the inner cavity of the screening cylinder, and the other end extends outward through the side cover of the screen cylinder.
[0015] Furthermore, a toothed ring is installed on the outer wall of the screening inner cylinder, and a drive motor is installed inside the cavity of the screening outer cylinder.
[0016] Furthermore, the output end of the drive motor is connected to a drive gear, which meshes with the gear ring.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This application features a set of airflow guide pipes horizontally installed inside the screening cylinder, connected to the blower compartment. The surface of the airflow guide pipes is covered with numerous airflow guide holes. After material is fed into the screening cylinder, the rotation of the screening cylinder causes the material to tumble. Under the action of the airflow, the remaining material is discharged, while the aluminum particles remain inside the screening cylinder cavity. This allows for rapid screening of aluminum ash. The discharge hopper opening on the side cover of the screen cylinder allows the concave surface of the discharge collection plate to face upward after the remaining material is discharged, driving the screening cylinder to continue rotating. This allows the aluminum particles to fall onto the top of the discharge collection plate. Since the discharge collection plate can be pulled out laterally at any time, the difficulty of removing the aluminum is greatly reduced, and the screening efficiency is improved.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-3 The system includes: an inner screening cylinder 1, an outer screening cylinder 2 installed at one end of the inner screening cylinder 1, and a screen cylinder side cover 4 installed at the other end of the inner screening cylinder 1. The outer screening cylinder 2 has a cylindrical structure, and its open end is fixed to the screen cylinder side cover 4, so that the inner screening cylinder 1 is placed inside the outer screening cylinder 2. An annular groove is formed on the inner wall of the outer screening cylinder 2. Two sets of annular sliders are fixed on the surface of the inner screening cylinder 1. The fit between the annular sliders and the annular groove allows the inner screening cylinder 1 to rotate freely within the cavity of the outer screening cylinder 2. A toothed ring 5 is formed on the outer wall of the outer screening cylinder 2. A drive toothed column 6 is provided on one side of part 5, and a drive motor 7 is connected to the center of the drive toothed column 6, so that the base of the drive motor 7 is connected to the outer screening cylinder 2. The drive toothed column 6 can drive the toothed ring part 5 to rotate through the drive motor 7, so that the entire inner screening cylinder 1 can rotate inside the outer screening cylinder 2. Multiple sets of annularly distributed baffles are provided inside the inner screening cylinder 1. The aluminum ash stored in the inner screening cylinder 1 is separated between the baffles. As the inner screening cylinder 1 rotates, the baffles can push the aluminum ash upward in a rotating manner and make the aluminum ash fall from a height.
[0025] Also includes:
[0026] An airflow guide pipe 10 is horizontally positioned at the center of the outer screening cylinder 2. The airflow guide pipe 10 extends outward through the outer screening cylinder 2 and connects to a blower chamber 11. A discharge collection pipe 12 is connected to the center of the screen cylinder side cover 4. One end of the discharge collection pipe 12 extends into the cavity of the inner screening cylinder 1, and the other end extends outward through the screen cylinder side cover 4. After the blower chamber 11 is started, airflow enters the airflow guide pipe 10. The airflow moves unidirectionally within the inner screening cylinder 1. During the falling of aluminum ash, the airflow can remove metallic aluminum particles. Biological material particles are blown into the discharge collection pipe 12. A collection bin is connected to the end of the discharge collection pipe 12 to collect biological material outside the aluminum particles, thereby achieving screening. To improve the efficiency of airflow, multiple sets of annular and radially distributed airflow guide holes 15 are opened on the surface of the inner screening cylinder 1, and each set of airflow guide holes 15 is inclined. Therefore, the airflow in the airflow guide pipe 10 can cover a large area inside the inner screening cylinder 1, thereby greatly improving screening efficiency and quality. Annular sliders are fixed on the opposite sides of the outer screening cylinder 2 and the side cover 4 of the screening cylinder. Supporting retaining rings 3 adapted to the annular sliders are opened at both ends of the inner screening cylinder 1 to help improve the stability of the rotation of the inner screening cylinder 1.
[0027] Airflow guide holes 15 are formed on the surface of airflow guide tube 10. Multiple sets of airflow guide holes 15 are formed along the surface of airflow guide tube 10. The airflow guide holes 15 are arranged in a ring array and also in a radial array distribution. Therefore, the entire surface of airflow guide tube 10 has multiple sets of air outlet holes. Since the extension distance of airflow guide tube 10 is relatively long, the airflow can be distributed in more positions inside the screening inner cylinder 1, thereby improving the screening quality of aluminum ash.
[0028] The discharge hopper 13 is located on the surface of the screen cylinder side cover 4. A discharge collection plate 14 is slidably connected to the groove of the discharge hopper 13. The inner wall of the screening outer cylinder 2 has a slot that fits the front end of the discharge collection plate 14. A cover plate connected to the screen cylinder side cover 4 is provided at the opening of the discharge hopper 13. The cover plate and the screen cylinder side cover 4 are connected by a rotating shaft. During screening, the cover plate is closed at the discharge hopper 13. When it is necessary to remove the aluminum particles, the discharge hopper 13 can be rotated forward and opened. Then, the front end of the discharge collection plate 14 is inserted into the discharge hopper 13 and moved horizontally until the front end of the discharge collection plate 14 abuts against the slot on the inner wall of the screening outer cylinder 2. This allows the discharge collection plate 14 to be horizontally mounted inside the screening inner cylinder 1, thus facilitating the discharge collection. The upper part of the collecting plate 14 is grooved, and the aluminum particles will fall into the upper part of the discharge collecting plate 14 for collection. The surface of the screening outer cylinder 2 is provided with a guide plate 8. One end of the guide plate 8 extends outward through the screening outer cylinder 2 and is connected to the guide bin 9. The top opening of the guide bin 9 is used to put in the aluminum ash to be screened. The cavity at the connection between the guide bin 9 and the guide plate 8 is inclined, so that the material will fall into the screening inner cylinder 1 along the inclined channel and the inclined channel of the guide plate 8.
[0029] 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.
