Description

Technical Field

[0001] This utility model belongs to the field of sorting device technology, and specifically relates to a sorting device for solid waste treatment. Background Technology

[0002] As the core pretreatment and grading unit of the solid waste screening system, the sorting device's technical performance directly determines the processing efficiency and accuracy of subsequent modules such as magnetic separation and photoelectric separation. The device achieves the separation of solid wastes of different particle sizes by creating relative displacement between the material and the screen holes through screen surface vibration or movement.

[0003] In traditional technical solutions, solid waste is often placed on a screen, and the solid waste can only fall through the screen holes at the bottom of the screen to complete the sorting, which can easily reduce work efficiency. During long-term use, the screen holes are easily deformed and worn due to the weight of the solid waste, requiring frequent screen replacement. Therefore, a sorting device for solid waste treatment is needed to solve the existing problems. Utility Model Content

[0004] This invention improves the efficiency of solid waste sorting and reduces the frequency of screen frame replacement through a specific screen frame structure.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sorting device for solid waste treatment, including a support frame, a screening shell hinged on the support frame, a first screening frame installed on the inner side of the screening shell, the first screening frame consisting of a bottom screen plate, a left screen plate, a right screen plate, and a rear screen plate, and a second screening frame consisting of a bottom screen plate, a left screen plate, and a right screen plate. This structural arrangement of the screening shell, the first screening frame, and the second screening frame allows medium-sized and small-sized solid waste to be separated from the screen holes on the bottom screen plate, left screen plate, right screen plate, and rear screen plate of the first screening frame, and allows small-sized solid waste to be separated from the screen holes on the bottom screen plate, left screen plate, and right screen plate of the second screening frame. The frame structure of the first and second screening frames reduces the probability of deformation in the short term.

[0006] Optionally, the screening shell is equipped with a support plate 1 and a support plate 2 for supporting the first screening frame. The support plate 1 and the support plate 2 can enhance the structural stability of the first screening frame and further prevent structural deformation caused by bearing the weight of solid waste for a long time.

[0007] Optionally, the support frame is equipped with a drive assembly for driving the screening shell to swing. The drive assembly includes a drive motor, a turntable is fixedly mounted on the drive shaft of the drive motor, an eccentric shaft is mounted on the turntable, and a drive rod is sleeved on the eccentric shaft. The drive rod is hinged to the screening shell, that is, while the turntable is rotating, it can drive the eccentric shaft and the drive rod to move closer to or away from the screening frame, thereby causing the screening frame to swing.

[0008] Optionally, the top of the screening shell is provided with a feed inlet that communicates with the inside of the first screening frame, that is, the feed inlet can directly restrict solid waste from entering the inside of the first screening frame.

[0009] Optionally, the screening shell is equipped with a discharge port 1 that communicates with the inside of the first screening frame and a discharge port 2 that communicates with the inside of the second screening frame. The end of the screening shell is connected to a discharge port 3. The discharge ports 1, 2 and 3 are used for discharging solid waste of different sizes.

[0010] Optionally, the support frame and the screening shell are connected by a hinged base, which allows the screening shell to swing freely.

[0011] Optionally, the bottom screen plate 1, the bottom screen plate 2, and the inner bottom of the screening shell are all inclined surfaces, which are respectively inclined downward along the direction of the discharge port 3. That is, the inclined surface is designed to facilitate the accumulation of solid waste at discharge port 1, discharge port 2, and discharge port 3.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The structural design of the screening shell, the first screening frame, and the second screening frame allows medium-sized and small-sized solid waste to be separated from the screen holes on the bottom screen plate 1, left screen plate 1, right screen plate 1, and rear screen plate of the first screening frame. It also allows small-sized solid waste to be separated from the screen holes on the bottom screen plate 2, left screen plate 2, and right screen plate 2 of the second screening frame. Compared to traditional technologies where materials can only be screened from the bottom of the screen, this design accelerates the sorting of solid waste and improves work efficiency. Furthermore, the frame structure of the first and second screening frames, compared to traditional wire mesh screens, reduces the probability of structural deformation in the short term and decreases the frequency of screen replacement.

[0013] 2. This utility model achieves efficient classification and treatment of solid waste according to particle size through the design of a multi-layer screening frame. The nested structure of the first and second screening frames ensures that larger solid particles are retained in the first screening frame, medium-sized particles fall through the sieve holes of the first screening frame into the second screening frame, and smaller particles finally fall into the outer shell of the screening frame, forming a three-stage sorting system and improving sorting accuracy.

[0014] 3. The eccentric shaft transmission structure adopted by the drive component makes the screening shell swing regularly, which further improves the material screening efficiency. At the same time, the reinforced design of the first and second support plates increases the load-bearing capacity of the first screening frame and can extend the service life of the equipment.

[0018] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0019] like Figure 1-5As shown, a solid waste treatment sorting device includes a support frame 1, a hinged base 11, a screening component 2, and a drive component 3. The support frame 1 consists of legs and a top plate. The bottom of the top plate is equipped with the hinged base 11. Four or more hinged bases 11 are arranged symmetrically front and back to improve the stability between the support frame 1 and the screening shell 21. The screening component 2 is hinged to the hinged base 11. The screening component 2 can sort solid waste of different particle sizes. The top of the support frame 1 is equipped with the drive component 3, which can drive the screening component 2 to swing back and forth.

[0020] like Figure 4 and Figure 5 As shown, the screening assembly 2 includes a screening shell 21, a first screening frame 22 and a second screening frame 23. The first screening frame 22 is composed of a bottom screen plate 221, a left screen plate 222, a right screen plate 223 and a rear screen plate 224. The second screening frame 23 is composed of a bottom screen plate 231, a left screen plate 232 and a right screen plate 233. A screening shell 21 is hinged to the hinged base 11 of the support frame 1. The interior of the screening shell 21 is a hollow cuboid structure. A first screening frame 22 is installed on one long side inside the screening shell 21. The first screening frame 22 can hold solid waste of all sizes. A second screening frame 23 is installed inside the screening shell 21, located outside the first screening frame 22. The first screening frame 22 can screen medium and small particle sizes of solid waste into the second screening frame 23. The second screening frame 23 can screen small particle sizes of solid waste into the inner bottom of the screening shell 21. The structural arrangement of the outer shell 21, the first screening frame 22, and the second screening frame 23 allows medium-sized and small-sized solid waste to be separated from the screen holes on the bottom screen plate 221, the left screen plate 222, the right screen plate 223, and the rear screen plate 224 of the first screening frame 22. Similarly, it allows small-sized solid waste to be separated from the screen holes on the bottom screen plate 231, the left screen plate 232, and the right screen plate 233 of the second screening frame 23. The frame structure of the first screening frame 22 and the second screening frame 23 reduces the probability of deformation in the short term and decreases the frequency of screen replacement compared to traditional technologies.

[0021] like Figure 1 , Figure 2 and Figure 5As shown, the screening assembly 2 also includes a first receiving plate 24, a second receiving plate 25, a feed inlet 26, a first discharge outlet 27, a second discharge outlet 28, and a third discharge outlet 29. The screening housing 21 is internally equipped with the first receiving plate 24 and the second receiving plate 25 for supporting the first screening frame 22. The first receiving plate 24 and the second receiving plate 25 enhance the structural stability of the first screening frame 22 and further prevent structural deformation caused by long-term bearing of the weight of solid waste. Both the first receiving plate 24 and the second receiving plate 25 are rectangular strips. The first receiving plate 24 is located at the bottom of the bottom screen plate 221 and its ends are fixedly connected to the inner wall of the screening housing 21. The two ends of the second receiving plate 25 are fixedly connected to the rear screen plate 224 and the inner wall of the screening housing 21, respectively.

[0022] The top of the screening shell 21 is provided with an inlet 26 that communicates with the interior of the first screening frame 22. The inlet 26 can directly limit solid waste from entering the interior of the first screening frame 22. The screening shell 21 is respectively equipped with an outlet 1 27 that communicates with the interior of the first screening frame 22 and an outlet 28 that communicates with the interior of the second screening frame 23. The outlet 1 27 and the outlet 28 are located on the front and rear sides of the screening shell 21, respectively. The end of the screening shell 21 is connected to an outlet 3 29. Larger particle sizes of solid waste flow out from outlet 1 27, medium particle sizes of solid waste flow out from outlet 28, and smaller particle sizes of solid waste flow out from outlet 3 29.

[0023] like Figure 2 and Figure 3 As shown, the drive assembly 3 includes a drive motor 31, a turntable 32, an eccentric shaft 33, and a drive rod 34. The support frame 1 is equipped with the drive assembly 3 for driving the screening housing 21 to swing. The drive assembly 3 includes a drive motor 31 mounted on the top plate of the support frame 1. A drive wheel, a conveyor belt, and a driven wheel are sequentially connected to the drive motor 31. A drive shaft is connected to the driven wheel, and a turntable 32 is fixedly mounted on the drive shaft. An eccentric shaft 33 is mounted on the turntable 32, and a drive rod 34 is sleeved on the eccentric shaft 33. The drive rod 34 is hinged to the screening housing 21 and to the left side wall of the screening housing 21. As the turntable 32 rotates, it can drive the eccentric shaft 33 and the drive rod 34 to move closer to or away from the screening frame, thereby causing the screening frame to swing and screen solid waste.

[0024] The bottom of the bottom screen plate 221, the bottom screen plate 231 and the inner bottom of the screening shell 21 are all inclined surfaces, and are set downward along the direction of the discharge port 29. The inclined surface makes it convenient for solid waste to gather at the discharge port 27, the discharge port 28 and the discharge port 29, and facilitates the material flow.

[0025] Working principle: When it is necessary to sort solid waste, the solid waste is poured into the first screening frame 22 through the feed port 26. At this time, the drive motor 31 in the drive assembly 3 is started. The drive shaft of the drive motor 31 drives the turntable 32 to rotate. The eccentric shaft 33 on the turntable 32 rotates accordingly. The eccentric shaft 33 drives the drive rod 34 to reciprocate. Since the drive rod 34 is hinged to the screening shell 21, the screening shell 21 will oscillate regularly.

[0026] During the oscillation of the screening outer shell 21, solid waste within the first screening frame 22 begins to be screened. Medium and smaller particle sizes of solid waste fall into the second screening frame 23 through the screen holes on the bottom screen plate 221, left screen plate 222, right screen plate 223, and rear screen plate 224 of the first screening frame 22. Larger particle sizes of solid waste remain within the first screening frame 22. Smaller particle sizes of solid waste entering the second screening frame 23 continue to be screened, falling into the inner bottom of the screening outer shell 21 through the screen holes on the bottom screen plate 231, left screen plate 232, and right screen plate 233 of the second screening frame 23.

[0027] Because the bottom screen plate 221, the bottom screen plate 231, and the inner bottom of the screening shell 21 are all set as inclined surfaces, and are inclined downwards along the direction of the discharge port 29, solid waste of different particle sizes will gather towards their respective discharge ports. Larger particle sizes of solid waste flow out from discharge port 27, medium particle sizes of solid waste flow out from discharge port 28, and smaller particle sizes of solid waste flow out from discharge port 29, thereby achieving efficient classification and sorting of solid waste according to particle size.

[0028] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
