Description

Technical Field

[0001] The invention relates to the technical field of construction waste regeneration, in particular to a construction waste regeneration aggregate light matter removal and collection device. Background Art

[0002] With the acceleration of urbanization, the amount of construction waste has increased dramatically, and recycling it has become an important measure for sustainable development. In the production process of recycled aggregates from construction waste, the removal of light materials is a key link. However, the existing light material removal and collection devices have many technical defects.

[0003] Many current devices have low separation efficiency when removing light materials. For example, some devices based on the principle of air separation cannot effectively separate light materials from recycled aggregates due to unreasonable design of the wind system, which makes it impossible to generate a stable and appropriately strong airflow. A large amount of light materials are still mixed in the aggregates, affecting the quality of the recycled aggregates and reducing the strength and stability of the materials in subsequent applications (such as concrete production). At the same time, the collection effect of the separated light materials is not good, and light materials often float around, which not only causes environmental pollution, but also makes it difficult to achieve centralized recycling of light materials, wasting resources.

[0004] The Chinese patent with the authorization announcement number CN117415130B discloses a construction waste recycled aggregate light material removal and collection device, which includes three elastic balance support structures, an eccentric rotating structure and a gas directional guide emission structure. The construction waste recycled aggregate light material removal and collection device can cause continuous longitudinal falling and bouncing movement between the construction waste recycled aggregate and the light material. Due to the different collision recovery coefficients of the two, the two will separate. At the same time, the high-speed flowing air generated can exert a lateral force on the construction waste recycled aggregate and the light material, so that the light material can be blown to the periphery by the high-speed flowing gas, so as to achieve the removal of the light material. In addition, since the longitudinal movement of the object and the movement of the gas are generated synchronously, it has adaptability between functions and improves the effective utilization rate of the drive motor.

[0005] However, there are still some problems with this application: the materials in this device are vibrated and blown by gas simultaneously, and the closer to the gas-directed emission structure, the stronger the wind. However, the wind cannot reach farther away, and vibration alone cannot effectively separate the recycled aggregate and light materials. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] This is the first embodiment of the present invention, which provides a light matter removal and collection device for recycled aggregate from construction waste.

[0038] Specifically, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , a housing assembly 100, comprising a sorting channel 101, a moving screen bed 102 and a roller 103 arranged on the inner wall of the sorting channel 101;

[0039] The screening assembly 200 includes a feeding channel 201 arranged on the outer wall of the sorting channel 101, a vibrating bed 202 is arranged in an array on the inner wall of the feeding channel 201, and a screening roller 203 is arranged on the end face of the vibrating bed 202, a moving part is arranged at the end of the vibrating bed 202 to drive the vibrating bed 202 to move at the end of the feeding channel 201, and the screening roller 203 moves at the end of the vibrating bed 202 to drive the material on the surface to move, and at the same time, the moving part drives the vibrating bed 202 to move to separate the material into layers;

[0040] A blowing component is also provided at the end of the vibrating bed 202 for blowing materials. When the materials fall from the current vibrating bed 202 to the next layer through the screening roller 203, the blowing component blows the materials in the falling process to further separate them.

[0041] The roller 103 is located between the moving screen bed 102 and the feeding channel 201. The building materials fall onto the vibrating bed 202 in the feeding channel 201. The materials are driven by the screening rollers 203 on the surface of the vibrating bed 202.

[0042] The moving parts will drive the vibration bed 202 to move inside the feeding channel 201, and the light materials such as plastic and the heavy materials such as sand and gravel in the material will be separated into layers through the up and down vibration of the vibration bed 202. Due to the different densities and weights of the two, when the vibration bed 202 vibrates, the speed and time of the light materials falling are different from those of the heavy materials. Finally, the light materials will gradually accumulate on the top of the heavy materials, and when the screening rollers 203 drive the materials to move, they will also break up the materials to prevent the light and heavy materials inside the materials from sticking together.

[0043] There are multiple vibrating beds 202 arranged in an internal array of the feeding channel 201, and there is a height difference between each vibrating bed 202. A blowing component is installed below the discharge end of each vibrating bed 202. When the material falls from the current vibrating bed 202 and enters the next vibrating bed 202, the blowing component blows on the material during the falling process. The heavy material is less affected by the wind due to its own weight density, while the light material is more affected by the wind, and is further separated from the heavy material in the falling material and floats on the upper layer of the material when falling on the surface of the next vibrating bed 202, which is helpful for the separation of light and heavy materials.

[0044] When the material falls from the last vibrating bed 202, it will fall on the top of the drum 103. The rotation of the drum 103 drives the material to move, and at this time, the blowing component under the last vibrating bed 202 continues to blow the material. When the drum 103 rotates, the heavy material will fall after passing through the drum 103 under the influence of the rotation of the drum 103. A small part will fall on the moving screen bed 102 on one side of the drum 103, and most of it will be discharged directly through the discharge port below. After being blown by the blowing component and driven by the rotation of the drum 103, the light material almost falls on the top of the moving screen bed 102 on the other side. The movement of the moving screen bed 102 drives the light material to move upward. In this process, the heavy material will fall downward from the moving screen bed 102, and only the light material will be driven and discharged by the moving screen bed 102.

[0045] Example 2

[0046] This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0047] Specifically, refer to Figure 6 , Figure 8 The moving part includes a base 206 installed at the end of the vibration bed 202, a rotating shaft 208 is arranged inside the base 206, and a convex plate 2081 is arranged at the end of the rotating shaft 208, the convex plate 2081 is arranged on the inner wall of the accommodating cavity 2061 opened on the inner wall of the base 206, the rotating shaft 208 extends to the outer wall of the base 206 away from the convex plate 2081 at one end and a pulley is arranged at the end, and the convex plate 2081 is driven to rotate inside the accommodating cavity 2061 by the pulley.

[0048] The base 206 is installed inside the feeding channel 201. Figure 5 As shown, the base 206 is installed with multiple bases 206 located below the vibrating bed 202, and the rotating shaft 208 passes through the bases 206 in the same row and is driven by the same pulley. The rotating shaft 208 is provided with a convex plate 2081 in the accommodating cavity 2061 inside the base 206, and the two convex plates 2081 are arranged opposite to each other and the top positions of the convex plates 2081 are connected together. The convex plates 2081 are driven by the rotating shaft 208 to rotate inside the accommodating cavity 2061.

[0049] Preferably, the end face of the convex plate 2081 is hinged with a connecting rod 2082 and the other end of the connecting rod 2082 is hinged with a moving block 209. When the convex plate 2081 rotates with the rotating shaft 208, the moving block 209 is driven to reciprocate on the inner wall of the fixed sleeve 2062 set on the end face of the base 206 through the connecting rod 2082.

[0050] Among them, Fig. 9 As shown, the connecting rod 2082 is located in the middle of the two convex plates 2081, and the other end of the connecting rod 2082 is hinged to the moving block 209. When the convex plate 2081 is driven by the rotating shaft 208 to rotate, the connecting rod 2082 moves inside the accommodating chamber 2061 together with the top part of the convex plate 2081, and deflects with the place where the rotating shaft 208 and the convex plate 2081 are connected as the axis. The connecting rod 2082 has a large movement range inside the accommodating chamber 2061. At the same time, the moving block 209 hinged at the other end of the connecting rod 2082 is restricted by the fixed sleeve 2062 and can only reciprocate up and down. Therefore, when the connecting rod 2082 is driven by the convex plate 2081 to move, it drives the moving block 209 to reciprocate inside the fixed sleeve 2062.

[0051] A connecting sleeve 2063 is also provided at the end of the base 206, and a connecting plate 207 is provided at the end of the connecting sleeve 2063. The connecting plate 207 is fixed to the end surface of the vibration bed 202. A first elastic member 2071 is provided on the end surface of the connecting plate 207, and the first elastic member 2071 extends to the inner wall of the connecting sleeve 2063. When the moving parts drive the vibration bed 202 to vibrate, the first elastic member 2071 is used for shock absorption.

[0052] Among them, the connecting plate 207 is fixed on the lower surface of the vibration bed 202 and is opposite to the base 206. The end of the first elastic member 2071 on the surface of the connecting plate 207 is located inside the connecting sleeve 2063 on the surface of the base 206. When the vibration bed 202 vibrates, shock absorption is performed by the first elastic members 2071 on both sides.

[0053] A connecting head 2072 is also provided on the end surface of the connecting plate 207 , and the connecting head 2072 extends to the inner wall of the fixing sleeve 2062 , and the connecting head 2072 reciprocates on the inner wall of the fixing sleeve 2062 .

[0054] Among them, the connecting head 2072 is fixed on the surface of the connecting plate 207, and the top end position enters into the interior of the fixed sleeve 2062 on the surface of the base 206. Through the connection between the connecting head 2072 and the fixed sleeve 2062, the connecting plate 207 and the base 206 are connected together to prevent the vibration bed 202 from shifting when vibrating.

[0055] Reference Fig. 9 , Fig.10A connecting rod 2073 is also provided on the inner wall of the connecting head 2072, and the end of the connecting rod 2073 passes through the inner wall of the moving rod 2091 provided at the end of the moving block 209, the end of the connecting rod 2073 extends to the inner wall of the moving rod 2091 and is provided with a connecting block 2074, and a second elastic member 2075 is sleeved on the end of the connecting rod 2073, and the end of the second elastic member 2075 facing away from the connecting block 2074 abuts against the inner wall of the moving rod 2091 for shock absorption.

[0056] The connector 2072 as a whole reciprocates inside the fixed sleeve 2062, and the connecting rod 2073 at the axis of the connector 2072 is connected to the moving block 209 moving inside the fixed sleeve 2062. Fig.10 As shown, the interior of the moving rod 2091 at the top of the moving block 209 is hollow, the top end of the connecting rod 2073 enters into the interior of the moving rod 2091 and is provided with a connecting block 2074 at the top end, and the second elastic member 2075 outside the connecting rod 2073 is between the inner wall of the connecting block 2074 and the moving rod 2091. When the distance between the connecting rod 2073 and the moving rod 2091 changes, the second elastic member 2075 acts as a buffer.

[0057] Better, refer to Figure 6 and Figure 7 The outer wall of the vibrating bed 202 is provided with a mounting shell 204, the array of screening rollers 203 is arranged inside the vibrating bed 202 and the ends of the screening rollers 203 extend to the inner wall of the mounting shell 204, the ends of the screening rollers 203 are provided with first rotating wheels 205, the ends of the adjacent screening rollers 203 are provided with connecting wheels 2051, the outer wall of the first rotating wheel 205 is connected with a first hydraulic rod 2052 and the other end of the first hydraulic rod 2052 is connected to the connecting wheel 2051, the outer wall of the connecting wheel 2051 is provided with a second hydraulic rod 2053 in array and the inner wall of the second hydraulic rod 2053 is connected to the first hydraulic rod 2052, and the end of the second hydraulic rod 2053 is provided with a second rotating wheel 2054, when the first rotating wheel 205 is close to the connecting wheel 2051, the length of the second hydraulic rod 2053 becomes longer so that the second rotating wheel 2054 is farther away from the outer wall of the connecting wheel 2051.

[0058] The screening rollers 203 are arranged in an array on the surface of the vibrating bed 202, and are matched in pairs. Figure 7As shown, the end of the sub-screening roller 203 extends to the inside of the mounting shell 204, the end of one sub-screening roller 203 is sleeved with a first rotating wheel 205, and the end of the other sub-screening roller 203 is sleeved with a connecting wheel 2051, and the surface of the connecting wheel 2051 is arrayed with a plurality of second hydraulic rods 2053, and the top of the second hydraulic rod 2053 is connected to the second rotating wheel 2054, the first hydraulic rod 2052 connects the first rotating wheel 205 and the connecting wheel 2051, and the hydraulic pressure inside the first hydraulic rod 2052 The oil is connected to the hydraulic oil inside the second hydraulic rod 2053, the first rotating wheel 205 and the second rotating wheel 2054 are driven by a belt, and the overall screening roller 203 is powered by another belt. When the screening roller 203 rotates on the surface of the vibrating bed 202 to transport the material, due to the different volume and weight of heavy materials, when encountering larger materials, the screening roller 203 is likely to get stuck. Therefore, the distance between the paired screening rollers 203 is changed to adapt to heavy materials of different volumes.

[0059] When the distance between the first rotating wheel 205 and the connecting wheel 2051 becomes larger, the first hydraulic rod 2052 becomes longer, and the hydraulic oil inside the second hydraulic rod 2053 enters into the first hydraulic rod 2052, so the second rotating wheel 2054 on the surface of the connecting wheel 2051 moves inward and moves closer to each other. When the distance between the first rotating wheel 205 and the connecting wheel 2051 becomes smaller, the hydraulic oil inside the first hydraulic rod 2052 enters into the second hydraulic rod 2053, so that the second rotating wheel 2054 expands outward, which can make the screening roller 203 adaptively adjust the spacing to adapt to the volume of the heavy material. At the same time, through the changes in the first rotating wheel 205 and the second rotating wheel 2054 on the surface of the connecting wheel 2051, the shape of the externally mounted belt is adjusted to keep the belt tensioned and avoid power interruption.

[0060] In summary, when in use, the convex plate 2081 in the accommodating cavity 2061 is driven to rotate by the rotating shaft 208 inside the base 206, and the convex plate 2081 is connected to the connecting rod 2082. When the top position of the convex plate 2081 rotates to the bottom of the accommodating cavity 2061, the bottom end position of the connecting rod 2082 is also located at the bottom of the accommodating cavity 2061. The other end of the connecting rod 2082 pulls the hinged moving block 209 to move downward inside the fixed sleeve 2062. When the moving block 209 moves downward, the upper moving rod 2091 moves downward together. The second elastic member 2075 is squeezed to deform it, and the connecting rod 2073 is pulled to make it move downward together with the moving rod 2091. Due to the buffering of the second elastic member 2075, the downward movement amplitude of the connecting rod 2073 is smaller than the downward movement amplitude of the moving rod 2091. At the same time, when the connecting rod 2073 moves downward, it pulls the connecting plate 207 downward together. The deformation of the first elastic member 2071 buffers the downward movement of the connecting plate 207. Multiple connecting plates 207 move downward synchronously, driving the vibrating bed 202 above to move downward.

[0061] When the rotating shaft 208 rotates so that the top of the convex plate 2081 is facing upward, the connecting rod 2082 pushes the moving block 209 to move upward inside the fixed sleeve 2062. When the moving rod 2091 is facing upward, the second elastic member 2075 loses the force of pulling downward, and the second elastic member 2075 and the first elastic member 2071 recover their deformation together. The connecting rod 2073 moves upward with the connecting plate 207, driving the vibrating bed 202 to move upward. This cycle is repeated, so that the vibrating bed 202 vibrates continuously on the surface of the feeding channel 201, driving the material above to vibrate together, and separating the light and heavy materials.

[0062] Example 3

[0063] This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0064] Specifically, refer to Figure 7 A limiting plate 2041 is disposed on the inner wall of the mounting shell 204 , and a third elastic member 2042 is disposed on the end surface of the limiting plate 2041 for pushing the first rotating wheel 205 to make it close to the connecting wheel 2051 .

[0065] Among them, the limiting plate 2041 is fixed inside the mounting shell 204, and the third elastic member 2042 on the surface contacts the first rotating wheel 205, and the first rotating wheel 205 is pushed to the connecting wheel 2051 on the other side through the third elastic member 2042. When the volume of material conveyed by the screening roller 203 is large, the first rotating wheel 205 is away from the connecting wheel 2051. At this time, the first rotating wheel 205 squeezes the third elastic member 2042. After the heavy material above is conveyed away, the third elastic member 2042 restores its deformation and pushes the first rotating wheel 205 to reset.

[0066] Preferably, refer to Figure 4 , Figure 5 The blowing component includes an air supply pipe 301 connected to the fan, the end of the air supply pipe 301 is connected to an air outlet pipe 302, and the end surface of the air outlet pipe 302 is provided with an air outlet 303, and the air outlet 303 is arranged at the end of the air pipe 302 inclined upward to blow light substances in the falling materials.

[0067] The air delivery pipe 301 is connected to the fan, and the wind generated by the fan enters the interior of the air duct 302 through the air delivery pipe 301 and blows outwards to the falling materials through the air outlet 303 to blow the light substances in the materials.

[0068] like Figure 5 As shown, the air outlet 303 blows out air at an inclined upward angle. When the material falls, the wind blown out of the air outlet 303 tends to be upward, avoiding the defect that the wind blown out of the straight air outlet may be blocked by the heavy material. The oblique upward blowing can also blow the light material blocked by the heavy material, separate it from the heavy material, and fall above the transported material with a parabolic downward trend.

[0069] Better, refer to Figure 1 to Figure 3 The motion screen bed 102 includes a mounting plate 1021, a motor 1022 is disposed on the end surface of the mounting plate 1021, a rotating shaft is disposed at the end of the motor 1022, a cam 1023 is sleeved on the outer wall of the rotating shaft, a motion plate 1024 is disposed on the outer wall of the cam 1023, and a sieve plate 1025 is disposed at the end of the motion plate 1024.

[0070] Among them, the moving screen bed 102 is installed inside the sorting channel 101 in an inclined posture as a whole, and the cams 1023 on both sides are driven to rotate by the motor 1022 on the surface of the lower mounting plate 1021. The initial installation angles of the cams 1023 on both sides are opposite. When rotating, the moving plates 1024 outside the cams 1023 on both sides show a difference in rotation height. Therefore, the upper screen plate 1025 also has an uneven movement pace. The heavy materials falling on the top of the screen plate 1025 are knocked down by the differential movement and tilt angle of the adjacent screen plates 1025, while the light materials are driven by the screen plate 1025 to move upward and finally discharged from the sorting channel 101.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
