Description

Technical Field

[0001] This utility model relates to the field of material sorting technology, and in particular to a mixed material sorting device. Background Technology

[0002] Construction waste refers to the waste generated during the construction, maintenance, and demolition of buildings. Construction waste affects environmental sanitation and living conditions, reduces soil quality and productivity, and contains many recyclable resources that can be utilized. Therefore, construction waste sorting devices are necessary.

[0003] Currently, the sorting of construction waste is mainly done through mechanical sorting. While mechanical sorting can achieve high-efficiency production, the sorting effect is not ideal. The content of light materials (wood chips, plastics, and other combustibles) in recycled aggregate (heavy materials after solid waste sorting) is still relatively high, which seriously affects the economic value and market role of recycled aggregate. In existing technologies, a screen plate, a blower, and a slag suction pipe are usually installed in the screening box. The blower and the slag suction pipe are distributed on both sides of the screen plate. The blower blows from bottom to top and the suction pipe sucks up the light materials in the construction waste. However, when the construction waste passes through the screen plate, the light materials fall through the screen plate to the bottom of the screening box. When the blower blows lightly, the light materials are blocked by the screen plate and the construction waste on the screen plate. The separation effect of heavy and light materials is poor, resulting in low purity of recycled aggregate. Utility Model Content

[0016] And / or, a second fixing member, wherein a second limiting groove is provided on the second side wall of the collecting member, a second fixing hole is provided on the second sieve plate, one end of the second fixing member can be connected to the second fixing hole, and the other end of the second fixing member is slidably connected to the second limiting groove, so that the second limiting groove can limit the rotation angle of the second sieve plate, and the other end of the second fixing member can abut against the outer wall surface of the second side wall.

[0017] Preferably, the slag suction pipe includes:

[0030] The beneficial effects of this utility model are:

[0031] This utility model provides a mixed material sorting device, which includes a collecting component, a screening component, and a slag suction component. The collecting component has a receiving cavity with at least one feed inlet. The screening component is disposed within the receiving cavity and includes a first screen plate and a second screen plate. Both the first and second screen plates are rotatably connected to a first side wall of the collecting component and are spaced apart vertically. The feed inlet is located on the first side wall, and the bottom of the feed inlet is higher than the top of the screening component. The slag suction component includes a slag suction pipe through which a high-speed airflow passes. The slag suction pipe communicates with the receiving cavity and is located between the first and second screen plates. The first screen plate, the second screen plate, and the slag suction pipe cooperate to form a sorting space for separating the mixed materials.

[0032] By setting up a collecting component and a first and second screen plate spaced vertically, the mixture falls into the first and second screen plates through the feed inlet. After being screened by the first and second screen plates, the mixture is classified. Additionally, a suction pipe is installed between the first and second screen plates, allowing light substances in the first layer of undersize material falling after screening to be sucked to the outside of the receiving cavity. Simultaneously, the first layer of undersize material bounces within the screen plate assembly, increasing the amount of material between the first and second screen plates. The residence time allows the lighter materials in the first layer of undersize material to be more fully sucked to the outside of the receiving cavity by the slag suction pipe. Through the arrangement of the first screen plate, the second screen plate and the slag suction assembly, a separation space for the mixed materials is formed in the receiving cavity. This allows the mixed materials to be more fully screened and classified through the coupling effect of mechanical separation and air separation, effectively separating the light and heavy materials in the mixed materials, improving the screening efficiency of the mixed materials, and achieving the effect of fully screening and classifying the mixed materials, thereby further improving the screening accuracy and purity of the mixed materials.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] like Figure 1 and Figure 2 As shown, this embodiment provides a mixed material sorting device, which includes a collecting component 4, a screening component 5, and a slag suction component 3. The collecting component 4 is provided with a receiving cavity 411 having at least one feed inlet. The screening component 5 is disposed in the receiving cavity 411 and includes a first screen plate 51 and a second screen plate 52. The first screen plate 51 and the second screen plate 52 are rotatably connected to the first side wall of the collecting component 4, and the first screen plate 51 and the second screen plate 52 are spaced apart in the vertical direction. The feed inlet is located on the first side wall, and the bottom of the feed inlet is higher than the top of the screening component 5. The slag suction component 3 includes a slag suction pipe 31, in which a high-speed airflow is introduced. The slag suction pipe 31 is connected to the receiving cavity 411 and is located between the first screen plate 51 and the second screen plate 52. The first screen plate 51, the second screen plate 52, and the slag suction pipe 31 cooperate to form a sorting space for separating the mixed materials.

[0050] By setting up a collection component 4 and a first screen plate 51 and a second screen plate 52 arranged vertically at intervals, the mixture falls onto the first screen plate 51 and the second screen plate 52 through the feed inlet. After being screened by the first screen plate 51 and the second screen plate 52, the mixture is screened and classified. In addition, a slag suction pipe 31 is set between the first screen plate 51 and the second screen plate 52, so that the light substances in the first layer of undersize material falling after the mixture is screened by the screening component 5 are sucked to the outside of the receiving cavity 411 by the slag suction pipe 31. At the same time, the first layer of undersize material will jump in the screening component 5, increasing the amount of the first layer of undersize material on the first screen plate 51. The residence time between the first screen plate 51 and the second screen plate 52 allows the lighter materials in the first layer of undersized material to be more fully sucked to the outside of the receiving cavity 411 by the slag suction pipe 31. Through the arrangement of the first screen plate 51, the second screen plate 52, and the slag suction assembly 3, a sorting space for separating the mixed materials is formed within the receiving cavity 411. This allows the mixed materials to be more fully screened and classified through the coupling effect of the screen plates and the airflow, effectively separating the lighter and heavier materials in the mixed materials, improving the screening efficiency, and achieving the effect of fully screening and classifying the mixed materials, thereby further improving the screening accuracy and purity of the mixed materials. It should be noted that in this embodiment, the first screen plate 51 is above the second screen plate 52, and the material that passes through the first screen plate 51 is the first layer of undersized material.

[0051] Furthermore, such as Figure 3 and Figure 4As shown, the aperture of the first sieve plate 51 is the same as that of the second sieve plate 52, or the aperture of the second sieve plate 52 is different from that of the first sieve plate 51. When the aperture of the first sieve plate 51 and the aperture of the second sieve plate 52 are the same, the sieve plates with the same aperture can ensure the consistency and stability of the screening process when screening materials with relatively uniform particle size distribution. When the aperture of the second sieve plate 52 is different from that of the first sieve plate 51, the mixture can be classified by the first sieve plate 51 and the second sieve plate 52, realizing the grading and screening of the mixture, so that the material can be accurately graded according to the expected standards, thereby ensuring the stability and reliability of product quality.

[0052] Optionally, such as Figure 2 and Figure 4 As shown, in this embodiment, the aperture of the first sieve plate 51 is larger than the aperture of the second sieve plate 52. During the screening of the mixture, materials larger than the aperture of the first sieve plate 51 are screened out by the first sieve plate 51, while materials smaller than the aperture fall from the first sieve plate 51 onto the second sieve plate 52. The use of the first sieve plate 51 and the second sieve plate 52 with different aperture sizes improves the screening efficiency and accuracy of the mixture, meeting higher requirements for refined material classification. This facilitates the smooth operation of subsequent production processes and enhances the economic efficiency and product quality of the entire production process.

[0053] Furthermore, such as Figure 2 and Figure 3 As shown, the first screen plate 51 includes a first screen plate body 511 and a first bent portion 512; wherein, the first end of the first bent portion 512 is fixedly connected to the first screen plate body 511, and the first bent portion 512 extends towards the feed inlet to form a second end. By setting the first bent portion 512, when the mixture falls onto the first screen plate 51, the first bent portion 512 provides a relatively fixed area for the mixture. The first bent portion 512 provides a relatively fixed area for the mixture, which can effectively guide the distribution range of the mixture, prevent the mixture from scattering randomly on the first screen plate 51, and prevent the mixture from falling into the second screen plate 52 below from the gap between the first screen plate 51 and the receiving cavity 411, so that the mixture can be more evenly distributed on the first screen plate body 511, improving the stability and reliability of the first screen plate 51.

[0054] Optionally, such as Figure 3As shown, the first sieve plate 51 also includes a first rotating shaft 513, which is fixedly connected to the first sieve plate body 511, and the first rotating shaft 513 is hinged to the first side wall of the collecting member 4. By setting the first rotating shaft 513, the first screen plate body 511 can rotate and swing moderately around the first rotating shaft 513 as the axis, giving the first screen plate 51 a certain degree of flexibility. The angle of the first screen plate body 511 can be adjusted according to the characteristics of the mixture. When the mixture is hard, the angle of the first screen plate body 511 is adjusted along the falling direction of the mixture to make the angle gentler, thereby avoiding damage to the first screen plate body 511 caused by rigid collision. When the mixture is soft, the angle of the first screen plate body 511 is adjusted along the falling direction of the mixture to make the angle steeper, so that the mixture jumps up after falling onto the first screen plate body 511 instead of sliding down the surface of the first screen plate body 511, which facilitates the screening of the mixture. By setting the first rotating shaft 513, the service life of the first screen plate 51 is effectively extended, and the stability and reliability of the mixture sorting device are ensured to a certain extent, so that the screening process of materials can be carried out more smoothly and efficiently.

[0055] Optionally, such as Figure 2 and Figure 4 As shown, in this embodiment, the second sieve plate 52 includes a second sieve plate body 521 and a third bending portion 522; wherein, the second sieve plate body 521 has a first through hole, the first end of the third bending portion 522 is fixedly connected to the second sieve plate body 521, and the third bending portion 522 extends along the direction of the falling mixture to form a second end. This allows the material under the first layer of sieves to be screened and classified again.

[0056] Optionally, such as Figure 4 As shown, the second sieve plate 52 also includes a second rotating shaft 523, which is fixedly connected to the second sieve plate body 521. The second rotating shaft 523 is hinged to the first side wall of the collecting member 4. This makes the angle of the second sieve plate body 521 adjustable, improving the applicability of the second sieve plate 52.

[0057] Specifically, the length of the first screen plate body 511 can be adjusted according to different mixtures, and similarly the length of the second screen plate body 521 can also be adjusted.

[0058] Furthermore, such as Figure 2 and Figure 5The mixture sorting device shown further includes a first fixing member (not shown in the figure) and / or a second fixing member (not shown in the figure); wherein, the second side wall of the collecting member 4 is provided with a first limiting groove 412, the first screen plate 51 is provided with a first fixing hole 5121, one end of the first fixing member can be connected to the first fixing hole 5121, and the other end of the first fixing member is slidably connected to the first limiting groove 412, so that the first limiting groove 412 can limit the rotation angle of the first screen plate 51, and the other end of the first fixing member can abut against the outer wall surface of the second side wall, and / or, the second side wall of the collecting member 4 is provided with a second limiting groove 413, the second screen plate 52 is provided with a second fixing hole 5221, one end of the second fixing member can be connected to the second fixing hole 5221, and the other end of the second fixing member is slidably connected to the second limiting groove 413, so that the second limiting groove 413 can limit the rotation angle of the second screen plate 52, and the other end of the second fixing member can abut against the outer wall surface of the second side wall. By setting the first fixing member and / or the second fixing member, the first screen plate 51 and / or the second screen plate 52 can be easily fixed after the angle is adjusted. This simplifies operation and ensures the stability of the first screen plate 51 and / or the second screen plate 52 during the screening process, preventing unnecessary shaking or displacement. It should be noted that in this embodiment, both the first and second fixing members are bolts. In other embodiments, the form of the first and second fasteners is not required and can be pins, etc.

[0059] Specifically, in this embodiment, the mixture sorting device includes a first fixing member and a second fixing member. This better enables the fixing of the first screen plate 51 and the second screen plate 52 after angle adjustment. It should be noted that both the first limiting groove 412 and the second limiting groove 413 are arc-shaped grooves. The arc-shaped grooves are more in line with the rotation path of the first screen plate 51 and the second screen plate 52, thus improving the screening efficiency.

[0060] Optionally, in this embodiment, the third sidewall of the collecting component 4 is also provided with a first limiting groove 412 and a second limiting groove 413. The third sidewall is arranged opposite to the second sidewall, and the second sidewall, the first sidewall, and the third sidewall are connected in sequence to form a U-shaped structure. This arrangement ensures that both sides of the first sieve plate 51 and the second sieve plate 52 are limited and fixed, avoiding shaking caused by uneven force. This makes the first sieve plate 51 and the second sieve plate 52 more stable when adjusting their angles, further ensuring screening efficiency.

[0061] Furthermore, such as Figure 1 and Figure 2As shown, the suction pipe 31 includes a flat-mouth section 311. Along the flow direction of the high-speed airflow within the suction pipe 31, the size of the flat-mouth section 311 gradually increases. The smallest end of the flat-mouth section 311 is connected to the receiving cavity 411. By setting the flat-mouth section 311, when the high-speed airflow passes through the smallest end of the flat-mouth section 311, the flow cross-section of the high-speed airflow decreases, increasing the suction force at the smallest end. This allows for more effective suction of light materials from the sorting space into the suction pipe 31, improving the efficiency and thoroughness of the mixed material screening. Furthermore, for some light materials that are far from the smallest end of the flat-mouth section 311, the greater suction force ensures that they can also be smoothly sucked into the suction pipe 31, which is beneficial for separating the first layer of undersize material between the first screen plate 51 and the second screen plate 52. It should be noted that in this embodiment, the flat-mouth pipe section 311 is in the form of a duckbill-shaped nozzle, with the duckbill end being the smallest end of the flat-mouth pipe section 311. This increases the communication area between the slag suction pipe 31 and the receiving cavity 411, and also increases the sorting space. In other embodiments, the flat-mouth pipe section 311 can also be in other forms, as long as it can achieve the suction of material between the first screen plate 51 and the second screen plate 52, and there are no restrictions here.

[0062] Optionally, such as Figure 2 As shown, in this embodiment, the slag suction pipe 31 further includes a constant-diameter pipe section 312. The constant-diameter pipe section 312 has a constant inner diameter and is connected to the largest end of the flat-mouth pipe section 311. A high-speed airflow passes through the constant-diameter pipe section 312. When the high-speed airflow enters the constant-diameter pipe section 312, the constant-diameter pipe section 312 can provide a stable flow channel for the high-speed airflow, so that the flow rate and pressure of the high-speed airflow can be maintained to a certain extent, thus providing a conveying pipeline for the high-speed airflow.

[0063] Optionally, such as Figure 5 As shown, in this embodiment, the slag suction assembly 3 further includes a suction pipe 32 and a fan 33. The first end of the suction pipe 32 is connected to the fan 33, and the other end of the suction pipe 32 is connected to the equal-diameter pipe section 312. The above configuration provides suction power at the flat-mouth pipe section 311.

[0064] Furthermore, such as Figure 5 and Figure 6As shown, the mixed material sorting device also includes a settling device 2. The settling device 2 has a cavity inside and two openings 21 and 22 spaced apart. Both openings 21 and 22 are connected to the cavity. The first opening 21 is connected to the slag suction pipe 31, and the second opening 22 allows a high-speed airflow to enter. By setting up the settling device 2, the smooth entry and exit of light materials and airflow is ensured. This allows the high-speed airflow carrying light materials in the slag suction pipe 31 to smoothly enter the cavity of the settling device 2. When the high-speed airflow is drawn from inside the settling device 2 to the second opening 22, an airflow field is formed within the cavity. Under the action of this airflow field, the trajectory of the light materials in the original high-speed airflow is disturbed and altered. The light materials drifting with the airflow gradually lose kinetic energy and begin to settle, allowing the light materials in the slag suction pipe 31 to enter the settling device 2 for settling and storage, preventing the light materials from entering the external environment and causing pollution. It should be noted that in this embodiment, the settling device 2 is a cyclone separator. Cyclone separators are existing technology, and their working principle and connection relationship will not be described in detail here.

[0065] Furthermore, the mixed material sorting device also includes a feeder 6, which is fixedly connected to the collecting component 4. One end of the feeder 6 is positioned corresponding to the feed inlet, and the mixed material is placed at the opposite end of the feeder 6. This arrangement allows the mixed material fed from the feeder 6 to smoothly and efficiently enter the receiving cavity 411 of the collecting component 4, providing a stable and continuous material supply for subsequent sorting processes. It should be noted that in this embodiment, the feeder 6 is a belt conveyor. Since belt conveyors are existing technology, they will not be described in detail here. In other embodiments, the feeder 6 can be of other types, which are not limited here, as long as they can automatically convey the mixed material.

[0066] Furthermore, such as Figure 5 As shown, the collector 4 includes a collector body 41 and a second bent portion 42. The feed inlet is located on the collector body 41. The first end of the second bent portion 42 is fixedly connected to the bottom of the feed inlet of the collector body 41. The second bent portion 42 extends upward to form a second end, and the second bent portion 42 is inclined towards the feeder 6 from its first end to its second end. When the feeder 6 is conveying the mixed materials, a small portion of the material may stick to the feeder 6, causing it to become stuck at the connection between the feeder 6 and the collector body 41. By providing the second bent portion 42, the material on the feeder 6 that does not fall onto the first screen plate body 511 is blocked and limited by the second bent portion 42, guiding the material to slide down into the receiving cavity 411 under the action of gravity, thus preventing material blockage.

[0067] Furthermore, such as Figure 5 and Figure 6As shown, the collecting component 4 has a discharge port, and the mixed material sorting device also includes a receiving machine 7. The discharge port is located on the side wall of the collecting component 4, one end of the receiving machine 7 is correspondingly positioned to the discharge port, and the other end of the receiving machine 7 is connected to a receiving component. This arrangement ensures that the separated material is smoothly discharged from the receiving cavity 411 through the discharge port, preventing material accumulation in the receiving cavity 411 and thus preventing the second screen plate 52 from becoming unadjustable, thereby improving the screening efficiency of the mixed material. It should be noted that in this embodiment, the discharge port and the feed port are positioned opposite each other, facilitating the flow of the mixed material.

[0068] Furthermore, such as Figure 5 and Figure 6 As shown, the mixed material sorting device also includes a support 1, and a settling device 2 is fixedly connected to the support 1. This provides an installation foundation for the settling device 2.

[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
