Description

Technical Field

[0001] This invention belongs to the field of waste brick processing technology, specifically a waste brick sorting and processing device and method. Background Technology

[0002] Waste bricks mainly originate from demolition debris, construction sites, or waste generated during building renovations. These bricks are considered waste after the buildings are demolished or renovated, as they are no longer needed. However, from a resource recycling perspective, these waste bricks are a type of recyclable waste. Because waste bricks have a certain recycling value, there is an urgent need for a waste brick processing device to handle them.

[0003] Conventional waste brick processing equipment mainly consists of a crushing device and a discharge device. In use, waste bricks are fed into the crushing device and crushed by the discharge device. Although this recycling method can crush all the bricks, some bricks that can be used directly are still in the waste bricks. This processing device cannot remove these bricks, resulting in low processing efficiency.

[0004] Meanwhile, in order to improve processing efficiency, the current waste brick processing equipment has an open design at the top of the crushing device and the bottom of the discharge device. In actual use, due to the rapid rotation of the crushing device, the bricks are crushed into powder, which generates a lot of dust and seriously affects the surrounding environment. Improvement is urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide a waste brick sorting and processing device and method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waste brick sorting and processing device, comprising a frame, a screening component movably engaged on the inner side of the top of the frame, the screening component shifting left and right relative to the frame, a recycling bin located below the screening component at the front end of the frame, an extension frame fixedly installed at the bottom of each recycling bin, the bottom of the extension frame being at the same level as the bottom of the frame, a crushing component fixedly installed at the rear end of the recycling bin, the top of the crushing component communicating with the bottom of the screening component, a dust suppression component installed on the right side of the crushing component, a linkage component above the dust suppression component, the bottom of the linkage component being connected to the crushing component, and the top of the linkage component being connected to the bottom of the screening component.

[0007] When using the device, the frame and the extension frame should be placed on a flat ground. The bottom of the crushing component should be kept at a certain height from the ground. A powder receiving box should be placed at the bottom of the crushing component, and corresponding waste bricks should be prepared to complete the initial preparation work.

[0008] As a further technical solution of the present invention, the screening component includes a screening plate, a guide plate is fixedly installed at the rear end of the screening plate, a recycling port is opened at the top of the screening plate near the front side, and waste ports are opened at equal intervals at the top of the screening plate near the right side.

[0009] As a further technical solution of the present invention, the bottom end of the recycling port is fixedly connected to a recycling pipe, the recycling pipe is located directly above the recycling box and is connected to the interior of the recycling box, the bottom end of the screening plate is provided with a waste hose, the number of waste ports is three and all of them are connected to the waste hose, and the bottom end of the waste hose is connected to the top end of the crushing component.

[0010] As a further technical solution of the present invention, guide grooves are provided on the front side of the screening plate and the rear side of the guide plate. The screening plate and the guide plate are movably engaged with the frame through the guide grooves, and the screening plate and the guide plate are displaced left and right relative to the frame.

[0011] The number of waste inlets can be adjusted as needed, and the size of the waste inlets can also be adjusted according to actual needs. Their maximum area must not exceed the area of ​​a complete brick, while the area of ​​the recycling inlet must be slightly larger than the area of ​​a normal brick. To prevent the bricks from breaking during screening, rubber pads for cushioning are pasted inside the guide plate, screening plate, and recycling pipe.

[0012] When screening waste bricks, multiple waste bricks can be fed into the screen through one end of the guide plate. The waste bricks will then be evenly and one by one fed into the top of the screening plate by the guide plate, waiting for the screening process.

[0013] As a further technical solution of the present invention, the crushing component includes a crushing box, the front end of the crushing box is connected to a recycling box, the bottom end of the crushing box is fixedly connected to a discharge box, and the top end of the crushing box is connected to the bottom end of a waste hose.

[0014] As a further technical solution of the present invention, a main shaft is movably installed in the middle of the crushing box, a crushing roller located inside the crushing box is fixedly installed on the outer side of the main shaft, a mounting base is fixedly installed at the rear end of the discharge box, and a motor is fixedly installed at the top of the mounting base.

[0015] As a further technical solution of the present invention, a first drive shaft is fixedly installed at the output end of the motor, and a second drive shaft is fixedly installed at one end of the main shaft near the linkage assembly. A synchronous belt is movably sleeved on the outer side of the first drive shaft, and the other end of the synchronous belt is movably sleeved on the outer side of the second drive shaft. The first drive shaft is connected to the second drive shaft through the synchronous belt.

[0016] When the screened waste bricks fall into the crushing box through the screening assembly, the motor starts and drives the first drive shaft to rotate. At this time, the second drive shaft is driven to rotate through the synchronous belt, which in turn drives the main shaft to rotate. The crushing rollers on the outer side of the main shaft rotate at high speed and come into contact with the waste bricks that have entered the crushing box. Combined with the collision with the inner wall of the crushing box, the crushing process of the waste bricks can be completed quickly. The crushed debris can be discharged through the discharge box.

[0017] As a further technical solution of the present invention, the linkage component includes a linkage frame, the top end of the linkage frame is connected to the bottom end of the screening plate, a fixed seat is fixedly installed at the bottom end of the linkage frame, a first connecting rod is movably connected to the bottom end of the fixed seat away from the bottom of the linkage frame through a rotating shaft, a second connecting rod is movably connected to the end of the first connecting rod away from the fixed seat through a rotating shaft, and the end of the second connecting rod away from the first connecting rod is connected to the main shaft.

[0018] Simultaneously, when the main shaft rotates, it can drive the second connecting rod to rotate in sync. At this time, the first connecting rod swings accordingly and applies pushing and pulling forces to the linkage frame. Since the screening plate and guide plate can only move left and right under the limiting action of the guide groove and the frame, the screening plate and guide plate can be driven to move back and forth to the left and right, and apply vibration to the bricks inside the screening plate. At this time, smaller bricks can be discharged through the waste port and enter the interior of the crushing component, while qualified bricks can be exported through the recycling port and enter the interior of the recycling box to complete the recycling, thereby completing the sorting and recycling process.

[0019] By setting waste inlet and recycling inlet at the top of the screening plate to distinguish bricks of different sizes, and by converting the power of brick crushing into the power of the screening plate reciprocating left and right, the system can quickly screen bricks of different sizes. Qualified bricks can be used directly, while unqualified bricks can be crushed directly, avoiding the decrease in processing efficiency caused by uniform crushing and improving the brick recycling efficiency.

[0020] At the same time, when qualified bricks fall into the recycling bin through the recycling pipe, the left and right reciprocating motion of the screening plate will drive the recycling pipe to reciprocate left and right. At this time, the recycling pipe can reciprocate left and right relative to the recycling bin, and the qualified bricks can be evenly distributed inside the recycling bin, thus completing the automatic placement process.

[0021] By reusing the power generated during brick crushing, and in conjunction with recycling pipes and bins, the device can quickly screen bricks and automatically place qualified bricks. The entire placement process is automated and requires no manual assistance, significantly improving the quality of brick recycling, increasing the usable amount of waste bricks, and reducing recycling costs.

[0022] As a further technical solution of the present invention, the dust suppression component includes a gas collection tank, the front end of the gas collection tank is connected to the mounting base, the top end of the gas collection tank is fixedly connected to an air inlet pipe, the bottom end of the gas collection tank is fixedly connected to an exhaust pipe, the output end of the air inlet pipe is located on one side of the bottom end of the discharge box, and a turbine fan is movably connected to the middle of the gas collection tank, one end of the turbine fan is connected to a first drive shaft.

[0023] Meanwhile, after the bricks are broken, the broken debris is discharged through the discharge box. At the same time, the rotation of the first drive shaft can drive the turbine fan to rotate rapidly. When the turbine fan rotates rapidly, it can generate negative pressure inside the air collection tank, and draw in external air into the air collection tank through the air inlet pipe. After being pressurized, the air is discharged through the exhaust pipe. At this time, the high-pressure air can act on the vicinity of the discharged debris, blowing away a large amount of dust and completing the auxiliary dust suppression process.

[0024] By utilizing the power of high-speed rotation during brick crushing, the bricks are quickly crushed into fragments through high-speed rotation, while the turbine fan rotates at high speed, thereby achieving rapid air intake. Finally, the high-speed airflow carries away the dust. The entire process is completed automatically and simultaneously with the brick crushing, which can significantly improve the surrounding environment during crushing and improve the crushing quality.

[0025] A method for processing waste bricks using a sorting and processing device includes the following steps:

[0026] S1: When processing waste bricks, the waste bricks can be fed in through the guide plate, and the motor can be turned on. The second link is driven to swing through the main shaft. At this time, the first link swings accordingly and applies pushing and pulling forces to the linkage frame.

[0027] S3: At this time, the screening plate can move the entire screening component back and forth under the guidance of the guide groove and the frame to screen the incoming bricks. When the bricks are small, they can be directly discharged through the waste port and enter the crushing component through the waste hose to wait for processing. When the bricks are large and meet the conditions for direct recycling, they can be directly discharged through the recycling port and introduced into the recycling box through the recycling pipe.

[0028] S4: As the recycling pipe moves back and forth, qualified waste bricks can be evenly placed inside the recycling box. At the same time, all the smaller waste bricks enter the crushing box and are crushed by the high-speed rotation of the main shaft and crushing roller. The crushed fragments are discharged through the discharge box.

[0029] S4: When the first drive shaft rotates, it can synchronously drive the turbine fan to rotate. At this time, negative pressure can be generated inside the air collection tank, and air can be drawn in through the air inlet pipe. After being pressurized by the turbine fan, it can be discharged through the exhaust pipe, which acts on the discharge process of the discharge box and assists in completing the dust reduction.

[0030] The beneficial effects of this invention are as follows:

[0031] 1. This invention distinguishes bricks of different sizes by setting a waste inlet and a recycling inlet at the top of the screening plate. At the same time, the power of crushing bricks is converted into the power of the screening plate reciprocating left and right, so as to quickly screen bricks of different sizes. Qualified bricks can be used directly, while unqualified bricks can be crushed directly, avoiding the decrease in processing efficiency caused by uniform crushing and improving the recycling efficiency of bricks.

[0032] 2. This invention utilizes the power of high-speed rotation during brick crushing. While rapidly crushing bricks into fragments through high-speed rotation, it also enables the high-speed rotation of the turbine fan, thereby achieving rapid air intake. Finally, the high-speed airflow carries away dust. The entire process is completed automatically and simultaneously with brick crushing, which can significantly improve the surrounding environment during crushing and improve the crushing quality.

[0033] 3. This invention reuses the power generated during brick crushing, and in conjunction with a recycling pipe and recycling bin, enables the device to quickly screen bricks and automatically place qualified bricks. The entire placement process is completed automatically without manual assistance, significantly improving the processing quality of brick recycling, increasing the usable amount of waste bricks, and reducing recycling costs.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] like Figures 1 to 8 As shown in the embodiment of the present invention, a waste brick sorting and processing device includes a frame 1. A screening component 2 is movably engaged on the inner side of the top of the frame 1. The screening component 2 moves left and right relative to the frame 1. A recycling box 3 is provided at the front end of the frame 1 below the screening component 2. An extension frame 4 is fixedly installed at the bottom of the recycling box 3. The bottom of the extension frame 4 is on the same horizontal plane as the bottom of the frame 1. A crushing component 5 is fixedly installed at the rear end of the recycling box 3. The top of the crushing component 5 is connected to the bottom of the screening component 2. A dust suppression component 7 is installed on the right side of the crushing component 5. A linkage component 6 is provided above the dust suppression component 7. The bottom of the linkage component 6 is connected to the crushing component 5, and the top of the linkage component 6 is connected to the bottom of the screening component 2.

[0045] When using the device, the frame 1 and the riser 4 should be placed on a flat ground. At the same time, the bottom of the crushing component 5 should be kept at a certain height from the ground. A powder receiving box should be placed at the bottom of the crushing component 5, and corresponding waste bricks should be prepared to complete the preliminary preparation work.

[0046] like Figure 1 and Figure 2 as well as Figure 3 As shown, the screening component 2 includes a screening plate 201, a guide plate 202 fixedly installed at the rear end of the screening plate 201, a recycling port 205 opened at the top of the screening plate 201 near the front side, and waste ports 204 opened at equal intervals at the top of the screening plate 201 near the right side. The bottom end of the recycling port 205 is fixedly connected to a recycling pipe 206, which is located directly above the recycling box 3 and is connected to the interior of the recycling box 3. The bottom end of the screening plate 201 is provided with a waste hose 207. There are three waste ports 204, all of which are connected to the waste hose 207. The bottom end of the waste hose 207 is connected to the top end of the crushing component 5. Guide grooves 203 are opened on the front side of the screening plate 201 and the rear side of the guide plate 202. The screening plate 201 and the guide plate 202 are movably engaged with the frame 1 through the guide grooves 203, and the screening plate 201 and the guide plate 202 can move left and right relative to the frame 1.

[0047] The number of waste inlets 204 can be adjusted as needed, and the size of the waste inlets 204 can also be adjusted according to actual needs. Its maximum area must not be greater than the area of ​​a complete brick, while the area of ​​the recycling inlet 205 needs to be slightly larger than the area of ​​a normal brick. To prevent the bricks from breaking during screening, rubber pads for buffering the structure are pasted inside the guide plate 202, the screening plate 201, and the recycling pipe 206.

[0048] When screening waste bricks, multiple waste bricks can be fed into the top of the screening plate 201 through one end of the guide plate 202. The waste bricks can then be evenly and one by one fed into the top of the screening plate 201 by the guide plate 202, waiting for the screening process.

[0049] like Figure 1 and Figure 4 as well as Figure 5 and Figure 6As shown, the crushing assembly 5 includes a crushing box 501. The front end of the crushing box 501 is connected to the recycling box 3. The bottom end of the crushing box 501 is fixedly connected to a discharge box 502. The top end of the crushing box 501 is connected to the bottom end of the waste hose 207. A main shaft 503 is movably installed in the middle of the crushing box 501. A crushing roller 504 located inside the crushing box 501 is fixedly installed on the outer side of the main shaft 503. A mounting base 505 is fixedly installed at the rear end of the discharge box 502. A motor 506 is fixedly installed at the top of the mounting base 505. A first drive shaft 507 is fixedly installed at the output end of the motor 506. A second drive shaft 508 is fixedly installed at one end of the main shaft 503 near the linkage assembly 6. A synchronous belt 509 is movably sleeved on the outer side of the first drive shaft 507. The other end of the synchronous belt 509 is movably sleeved on the outer side of the second drive shaft 508. The first drive shaft 507 is connected to the second drive shaft 508 through the synchronous belt 509.

[0050] When the screened waste bricks fall into the crushing box 501 through the screening component 2, the start of the motor 506 drives the first drive shaft 507 to rotate. At this time, the second drive shaft 508 is driven to rotate through the synchronous belt 509, which in turn drives the main shaft 503 to rotate. The crushing roller 504 on the outer side of the main shaft 503 rotates at high speed and comes into contact with the waste bricks that have entered the crushing box 501. The collision between the rollers and the inner wall of the crushing box 501 quickly completes the crushing process of the waste bricks. The crushed debris can be discharged through the discharge box 502.

[0051] like Figure 1 and Figure 4 as well as Figure 7 As shown, the linkage assembly 6 includes a linkage frame 601. The top end of the linkage frame 601 is connected to the bottom end of the screening plate 201. A fixed seat 602 is fixedly installed at the bottom end of the linkage frame 601. A first connecting rod 603 is movably connected to the bottom end of the fixed seat 602 away from the bottom end of the linkage frame 601 through a rotating shaft. A second connecting rod 604 is movably connected to the end of the first connecting rod 603 away from the fixed seat 602 through a rotating shaft. The end of the second connecting rod 604 away from the first connecting rod 603 is connected to the main shaft 503.

[0052] Example: When the main shaft 503 rotates, it can synchronously drive the second connecting rod 604 to rotate. At this time, the first connecting rod 603 swings accordingly and applies pushing and pulling forces to the linkage frame 601. Since the screening plate 201 and the guide plate 202 can only move left and right under the limiting action of the guide groove 203 and the frame 1, the screening plate 201 and the guide plate 202 can be driven to move back and forth, and apply vibration to the bricks inside the screening plate 201. At this time, smaller bricks can be discharged through the waste port 204 and enter the interior of the crushing component 5, while qualified bricks can be exported through the recycling port 205 and enter the interior of the recycling box 3 to complete the recycling, thereby completing the sorting and recycling process.

[0053] By setting a waste inlet 204 and a recycling inlet 205 at the top of the screening plate 201 to distinguish bricks of different sizes, the power of brick crushing is converted into the power of the screening plate 201 reciprocating left and right, which can quickly achieve the screening of bricks of different sizes. Qualified bricks can be used directly, while unqualified bricks can be crushed directly, avoiding the decrease in processing efficiency caused by uniform crushing and improving the brick recycling efficiency.

[0054] At the same time, when qualified bricks fall into the recycling box 3 through the recycling pipe 206, the left and right reciprocating motion of the screening plate 201 will drive the recycling pipe 206 to reciprocate left and right. At this time, the recycling pipe 206 can reciprocate left and right relative to the recycling box 3. The qualified bricks can then be evenly distributed inside the recycling box 3, completing the even placement of qualified bricks and the automatic placement process.

[0055] By reusing the power generated during brick crushing, and in conjunction with the recycling pipe 206 and recycling box 3, the device can quickly screen bricks and automatically place qualified bricks. The entire placement process is completed automatically without manual assistance, which significantly improves the processing quality of brick recycling, increases the usable amount of waste bricks, and reduces recycling costs.

[0056] like Figure 1 and Figure 4 as well as Figure 8 As shown, the dust collection assembly 7 includes a gas collection tank 701. The front end of the gas collection tank 701 is connected to the mounting base 505. An air inlet pipe 702 is fixedly connected to the top of the gas collection tank 701, and an exhaust pipe 703 is fixedly connected to the bottom of the gas collection tank 701. The output end of the air inlet pipe 702 is located on one side of the bottom of the discharge box 502. A turbine fan 704 is movably connected to the middle of the gas collection tank 701. One end of the turbine fan 704 is connected to the first drive shaft 507.

[0057] Example: Simultaneously, after the brick is broken, the broken debris is discharged through the discharge box 502. At the same time, the rotation of the first drive shaft 507 can drive the turbine fan 704 to rotate rapidly. When the turbine fan 704 rotates rapidly, a negative pressure is generated inside the air collection tank 701, and external air is quickly drawn into the air collection tank 701 through the air inlet pipe 702. After being pressurized, it is discharged through the exhaust pipe 703. At this time, the high-pressure air can act on the vicinity of the discharged debris, blowing away a large amount of dust and completing the auxiliary dust reduction process.

[0058] By utilizing the power of high-speed rotation during brick crushing, the bricks are quickly crushed into fragments through high-speed rotation, while the turbine fan 704 rotates at high speed, thereby achieving rapid air intake. Finally, the high-speed airflow carries away the dust. The entire process is completed automatically and simultaneously with the brick crushing, which can significantly improve the surrounding environment during crushing and improve the crushing quality.

[0059] A method for processing waste bricks using a sorting and processing device includes the following steps:

[0060] S1: When processing waste bricks, waste bricks can be put in through guide plate 202, and motor 506 is turned on. The second connecting rod 604 is driven to swing through main shaft 503. At this time, the first connecting rod 603 swings accordingly and applies pushing and pulling force to linkage frame 601.

[0061] S2: At this time, under the guidance of the guide groove 203 and the frame 1, the screening plate 201 can drive the entire screening component 2 to move back and forth to screen the incoming bricks. When the bricks are small, they can be directly discharged through the waste port 204 and enter the crushing component 5 through the waste hose 207 to wait for processing. When the bricks are large and meet the conditions for direct recycling, they can be directly discharged through the recycling port 205 and introduced into the recycling box 3 through the recycling pipe 206.

[0062] S3: As the recycling pipe 206 moves back and forth, qualified waste bricks can be evenly placed inside the recycling box 3. At the same time, all the smaller waste bricks enter the crushing box 501 and are crushed by the high-speed rotation of the main shaft 503 and the crushing roller 504. The crushed fragments are discharged through the discharge box 502.

[0063] S4: When the first drive shaft 507 rotates, it can synchronously drive the turbine fan 704 to rotate. At this time, a negative pressure can be generated inside the air collection tank 701, and air is drawn in through the air inlet pipe 702. After being pressurized by the turbine fan 704, it is discharged through the exhaust pipe 703, which acts on the discharge process of the discharge box 502 and assists in completing the dust reduction.

[0064] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.

A second connecting rod (604) is movably connected to the end of the first connecting rod (603) away from the fixed seat (602) via a rotating shaft. The end of the second connecting rod (604) away from the first connecting rod (603) is connected to the main shaft (503).

5. The waste brick sorting and processing device according to claim 4, characterized in that: The dust suppression assembly (7) includes a gas collection tank (701), the front end of which is connected to the mounting base (505), the top end of which is fixedly connected to an air inlet pipe (702), the bottom end of which is fixedly connected to an exhaust pipe (703), the output end of which is located on one side of the bottom end of the discharge box (502), and a turbine fan (704) is movably connected to the middle of the gas collection tank (701), one end of which is connected to the first drive shaft (507).

6. The processing method of the waste brick sorting and processing device according to claim 5, characterized in that: Includes the following steps: S1: When processing waste bricks, waste bricks are fed in through the guide plate (202), and the motor (506) is turned on. The second link (604) is driven to swing through the main shaft (503). At this time, the first link (603) swings accordingly and applies pushing and pulling forces to the linkage frame (601). S2: At this time, under the guidance of the guide groove (203) and the frame (1), the screening plate (201) drives the entire screening component (2) to move back and forth to screen the incoming bricks. When the bricks are small, they are directly discharged through the waste port (204) and enter the crushing component (5) through the waste hose (207) to wait for processing. When the bricks are large and meet the conditions for direct recycling, they are directly discharged through the recycling port (205) and introduced into the recycling box (3) through the recycling pipe (206). S3: As the recycling pipe (206) moves back and forth, the qualified waste bricks are evenly placed inside the recycling box (3), while all the smaller waste bricks enter the crushing box (501) and are crushed by the high-speed rotation of the main shaft (503) and the crushing roller (504). The crushed fragments are discharged through the discharge box (502). S4: When the first drive shaft (507) rotates, it synchronously drives the turbine fan (704) to rotate. At this time, a negative pressure is generated inside the air collection tank (701), and air is drawn in through the air inlet pipe (702). After being pressurized by the turbine fan (704), the air is discharged through the exhaust pipe (703), which acts on the discharge process of the discharge box (502) to assist in completing the dust reduction.
