Description

Technical Field

[0001] The invention belongs to the technical field of waste brick processing, and specifically relates to a waste brick classification processing device and a processing method. Background Art

[0002] Waste bricks mainly come from building demolition waste, construction sites or waste generated during house renovation. After the building is demolished or renovated, these bricks are considered waste because they are no longer needed. From the perspective of resource recycling, these waste bricks are a kind of recyclable waste. Since waste bricks have a certain recycling value, there is an urgent need for a waste brick processing device to process the waste bricks.

[0003] The conventional waste brick processing device mainly consists of a crushing device and a discharging device. When in use, the waste bricks are put into the crushing device and crushed by the discharging device. Although this recycling method can crush all the bricks, there are still some bricks that can be directly used in the waste bricks, and this processing device cannot remove these bricks, resulting in low processing efficiency.

[0004] At the same time, in order to improve the processing efficiency, the top of the crushing device and the bottom of the discharging device of the current waste brick processing device are in an open design. In actual use, due to the rapid rotation of the crushing device, the bricks are crushed into powder, which will generate a large amount of dust, seriously affecting the surrounding environment, and urgently needs to be improved. Summary of the invention

[0007] When the device is in use, the frame and the heightening frame need to be placed on a flat ground. At the same time, the bottom of the crushing assembly needs to be kept at a certain height from the ground. A powder receiving box is placed at the bottom of the crushing assembly, and corresponding waste bricks are prepared to complete the preliminary preparations.

[0008] As a further technical solution of the present invention, the screening assembly includes a screening plate, a guide plate is fixedly installed at the rear end of the screening plate, a recovery port is opened at the top of the screening plate near the front side, and a waste port is opened at an equal distance 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 recovery port is fixedly connected to a recovery pipe, the recovery pipe is located directly above the recovery box, and the recovery pipe is connected to the interior of the recovery box. A waste hose is provided at the bottom end of the screening plate. There are three waste ports and all are connected to the waste hose. The bottom end of the waste hose is connected to the top of the crushing assembly.

[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 connected to the frame through the guide grooves, and the screening plate and the guide plate are displaced left and right relative to the frame.

[0011] Among them, the number of waste ports can be adjusted according to needs, and the size of the waste ports can also be adjusted according to actual needs. The maximum area shall not be larger than the area of ​​a complete brick, and the area of ​​the recovery port shall be slightly larger than the area of ​​a normal brick. In order to prevent bricks from breaking during screening, rubber pads for buffering construction are pasted on the guide plate, screening plate and the inside of the recovery pipe.

[0012] When screening discarded bricks, multiple discarded bricks can be put in through one end of the guide plate. At this time, the discarded bricks can be evenly and one by one sent to the top of the screening plate through the guidance of the guide plate, waiting for the screening process.

[0013] As a further technical solution of the present invention, the crushing assembly includes a crushing box, the front end of the crushing box is connected to the recycling box, the bottom end of the crushing box is fixedly connected to the discharge box, and the top end of the crushing box is connected to the bottom end of the 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 seat is fixedly installed at the rear end of the discharge box, and a motor is fixedly installed on the top of the mounting seat.

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

[0016] When the screened discarded bricks fall into the crushing box through the screening assembly, the first transmission shaft can be driven to rotate due to the start of the motor. At this time, the second transmission shaft can be driven to rotate through the synchronous belt, and the main shaft can be driven to rotate. The crushing roller on the outer side of the main shaft rotates at high speed and contacts with the discarded bricks entering the crushing box. Combined with the collision with the inner wall of the crushing box, the crushing process of the discarded bricks can be quickly completed, and the crushed debris can be discharged through the discharge box.

[0017] As a further technical solution of the present invention, the linkage assembly includes a linkage frame, the top of the linkage frame is connected to the bottom end of the screening plate, the bottom end of the linkage frame is fixedly installed with a fixed seat, the bottom end of the fixed seat away from the linkage frame is movably connected to a first connecting rod through a rotating shaft, the end of the first connecting rod away from the fixed seat is movably connected to a second connecting rod 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] At the same time, when the main shaft rotates, it can synchronously drive the second connecting rod to rotate. At this time, the first connecting rod swings accordingly, and applies thrust and pulling force to the linkage frame. Since the screening plate and the guide plate can only move left and right under the limiting effect of the guide groove and the frame, the screening plate and the guide plate can be driven to move back and forth left and right, and vibration can be applied 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 assembly, while qualified bricks can be discharged through the recycling port and enter the interior of the recycling box to complete recycling, thereby completing the classification and recycling process.

[0019] A waste port and a recycling port are provided at the top of the screening plate to distinguish bricks of different sizes. At the same time, the power of brick crushing is converted into the power of the screening plate to move back and forth left and right, so that bricks of different sizes can be quickly screened, qualified bricks can be directly used, and unqualified bricks can be directly crushed, avoiding the decrease in processing efficiency caused by unified crushing and improving the recycling efficiency of bricks.

[0020] At the same time, when qualified bricks fall into the recycling box through the recycling pipe, the left and right movement of the screening plate can drive the recycling pipe to move back and forth. At this time, the recycling pipe can move back and forth relative to the recycling box. At this time, the exported qualified bricks can be evenly arranged in the recycling box, and the qualified bricks can be evenly placed, completing the automatic placement process.

[0021] By reusing the power of brick crushing and cooperating with recycling pipes and recycling boxes, 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 discarded bricks, and reduces recycling costs.

[0022] As a further technical solution of the present invention, the dust reduction component includes an air collecting tank, the front end of the air collecting tank is connected to the mounting seat, the top of the air collecting tank is fixedly connected to an air intake pipe, the bottom end of the air collecting tank is fixedly connected to an exhaust pipe, the output end of the air intake pipe is located on one side of the bottom end of the discharge box, and the middle part of the air collecting tank is movably connected to a turbine fan, and one end of the turbine fan is connected to the first transmission shaft.

[0023] At the same time, after the bricks are broken, the broken debris is discharged through the discharge box. At the same time, the rotation of the first transmission shaft can drive the turbofan to rotate rapidly. When the turbofan rotates rapidly, negative pressure can be generated inside the air collecting tank, and the external air can be quickly sucked into the air collecting tank through the air intake pipe, and discharged through the exhaust pipe after pressurization. At this time, the high-pressure air can act on the vicinity of the discharged debris, blow away a large amount of dust, and complete the auxiliary dust reduction process.

[0024] By utilizing the power of high-speed rotation when bricks are broken, the bricks can be quickly broken into debris through high-speed rotation, and the high-speed rotation of the turbine fan can be achieved, thereby achieving rapid air intake, and finally using high-speed flowing air to take away dust. The whole process is completed automatically and carried out simultaneously with the breaking of bricks, which can significantly improve the surrounding environment during crushing and improve the crushing quality.

[0025] A method for treating waste bricks by a classification and treatment device, comprising the following steps: S1: When processing waste bricks, the waste bricks can be put in through the guide plate, and the motor is turned on, and the second connecting rod is driven to swing through the main shaft, and the first connecting rod swings accordingly, and applies thrust and pull to the linkage frame; S3: At this time, the screening plate can drive the entire screening assembly to move back and forth left and right 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 assembly through the waste hose to wait for processing. When the bricks are large and meet the direct recycling conditions, they can be directly discharged through the recycling port and introduced into the recycling box through the recycling pipe. S4: As the recycling pipe moves back and forth left and right, qualified waste bricks can be evenly placed inside the recycling box, while smaller waste bricks all enter the crushing box and are crushed by the high-speed rotation of the main shaft and the crushing roller. The crushed fragments are discharged through the discharge box; S4: When the first transmission shaft rotates, the turbine fan can be driven to rotate synchronously, and negative pressure can be generated inside the air collecting tank. Air is sucked in through the air intake pipe, and discharged through the exhaust pipe after being pressurized by the turbine fan, acting on the discharge process of the discharge box to assist in dust reduction.

[0026] The beneficial effects of the present invention are as follows: 1. The present invention provides a waste port and a recovery port at the top of the screening plate to distinguish bricks of different sizes, and at the same time converts the power of brick crushing into the power of the screening plate to move back and forth, so as to quickly screen bricks of different sizes, directly utilize qualified bricks, and directly crush unqualified bricks, thereby avoiding the decrease in processing efficiency caused by unified crushing and improving the recovery efficiency of bricks.

[0027] 2. The present invention utilizes the power of high-speed rotation when the bricks are broken. While quickly breaking the bricks into debris through high-speed rotation, it can also realize high-speed rotation of the turbine fan, thereby realizing rapid air intake, and finally using high-speed flowing air to take away the dust. The whole process is completed automatically and is carried out simultaneously with the breaking of the bricks, which can significantly improve the surrounding environment during breaking and improve the breaking quality.

[0028] 3.

In order to prevent the bricks from breaking during screening, rubber pads for buffering construction are pasted on the inside of the guide plate 202, the screening plate 201 and the recovery pipe 206.

[0035] When screening discarded bricks, multiple discarded bricks can be thrown in through one end of the guide plate 202. At this time, the discarded bricks can be evenly and one by one sent to the top of the screening plate 201 through the guidance of the guide plate 202, waiting for the screening process.

[0036] like Figure 1 and Figure 4 as well as Figure 5 and Figure 6 As 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 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 seat 505 is fixedly installed at the rear end of the discharge box 502, a motor 506 is fixedly installed on the top of the mounting seat 505, a first transmission shaft 507 is fixedly installed on the output end of the motor 506, a second transmission shaft 508 is fixedly installed on one end of the main shaft 503 close to the linkage assembly 6, a synchronous belt 509 is movably sleeved on the outer side of the first transmission shaft 507, the other end of the synchronous belt 509 is movably sleeved on the outer side of the second transmission shaft 508, and the first transmission shaft 507 is transmission-connected to the second transmission shaft 508 via the synchronous belt 509.

[0037] When the screened discarded bricks pass through the screening component 2 and fall into the crushing box 501, the first transmission shaft 507 can be driven to rotate due to the start of the motor 506.

[0039] Embodiment: When the main shaft 503 rotates, the second connecting rod 604 can be driven to rotate synchronously. At this time, the first connecting rod 603 swings accordingly, and applies thrust and pulling force to the linkage frame 601. Since the screening plate 201 and the guide plate 202 can only be displaced 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 left and right, and vibration can be applied to the bricks inside the screening plate 201.

At this time, the high-pressure air can act on the vicinity of the discharged debris, blow away a large amount of dust, and complete the auxiliary dust reduction process.

[0045] By utilizing the power of high-speed rotation when the bricks are broken, the bricks can be quickly broken into debris through high-speed rotation, and the turbofan 704 can also rotate at high speed, thereby achieving rapid air intake, and finally using high-speed flowing air to take away dust. The whole process is completed automatically and is carried out simultaneously with the breaking of the bricks, which can significantly improve the surrounding environment during breaking and improve the breaking quality.

When the bricks are large and meet the direct recycling conditions, they can be 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 left and right, qualified waste bricks can be evenly placed inside the recycling box 3, while all 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 transmission shaft 507 rotates, the turbine fan 704 can be driven to rotate synchronously. At this time, negative pressure can be generated inside the air collecting tank 701, and air is sucked in through the air intake pipe 702.
