Description

Technical Field

[0001] This invention relates to the field of construction waste brick screening equipment, and in particular to a construction waste brick screening and recycling device with detection function. Background Technology

[0002] Waste bricks are a major component of construction waste, and their resource utilization level and methods directly affect the process of construction waste resource utilization and industrialization. The resource utilization of waste bricks is of great significance for developing a circular economy and protecting the environment. Currently, waste brick processing equipment primarily uses crushing to pulverize waste bricks, with the resulting aggregate used for recycled concrete. However, existing waste brick processing equipment lacks the function of screening intact bricks, resulting in the crushing of even well-shaped bricks. In conclusion, existing waste brick processing equipment has the problem of not being able to screen out intact bricks. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a construction waste brick screening and recycling device with detection function to solve the problem that existing waste brick processing equipment cannot screen out whole bricks.

[0004] The present invention solves the above-mentioned technical problems through the following technical means:

[0005] A construction waste brick screening and recycling device with detection function includes a first conveying mechanism, a second conveying mechanism, an orienting component, and a screening mechanism. The first conveying mechanism is a horizontal conveying mechanism. The second conveying mechanism is installed at the outlet of the first conveying mechanism, with its inlet flush with the outlet. The outlet of the second conveying mechanism is vertically arranged on both sides. Both sides of the upper surface of the second conveying mechanism are provided with chutes, which are always aligned with the upper surface of the second conveying mechanism. Rollers are installed inside the chutes. The orienting component is installed at the outlet of the second conveying mechanism and has a frame structure. The height of the inner frame of the orienting component is equal to the width of the brick when it is laid flat. The screening mechanism is installed at the outlet of the orienting component and is a conveying mechanism with an opening. The opening is connected by telescopic rods at the front and rear ends. It also includes support rods set on both sides of the front and rear ends of the opening. The tops of the support rods located at the same end are connected by a rotating shaft. The rotating shaft is rotatably connected to the support rods. The vertical height of the rotating shaft from the opening is equal to the width of the brick when it is laid flat. The first conveying mechanism transfers the bricks to the second conveying mechanism, which stands the bricks upright. The orientation component unifies the side orientation of all the bricks, and then the bricks are transferred to the screening mechanism. When the bricks pass through the opening, the complete bricks pass directly horizontally through the opening under the pressure of the rotating shaft, while the incomplete bricks fall directly from the opening because they are not subjected to the pressure of the rotating shaft. This achieves the function of screening out complete bricks.

[0006] Furthermore, the directional assembly is equipped with grinding wheels at both the top and bottom, with the distance between the two grinding wheels equal to the height of the inner frame of the directional assembly. The grinding wheels can grind away the concrete adhering to the bricks.

[0007] Furthermore, the support rod is a height-adjustable telescopic rod, which facilitates the selection of bricks of different sizes.

[0008] Furthermore, a cleaning mechanism is installed at the opening. This mechanism includes a base plate, a laser sensor, and an electrically controlled telescopic rod. The base plate is slidably connected to the inner wall of the opening. The laser sensor and the electrically controlled telescopic rod are both installed on the inward-facing side of the base plate, and the extension and retraction of the electrically controlled telescopic rod are controlled by the laser sensor. This cleaning mechanism can remove bricks stuck in the opening, ensuring continuous operation of the equipment.

[0009] Furthermore, electrically controlled telescopic rods are installed at both ends of the base plate. Pushing the waste bricks from both ends facilitates their falling off.

[0010] Furthermore, the outlet of the screening mechanism is equipped with a container for collecting bricks, facilitating the collection of intact bricks.

[0011] Furthermore, a crusher for shredding waste bricks is installed at the bottom of the opening. Waste bricks fall directly into the crusher through the opening, where they are directly shredded.

[0012] Furthermore, the first conveying mechanism is a vibrating transmission belt. The vibrating design facilitates the pre-leveling of bricks on the conveyor belt, avoiding manual brick leveling and increasing the degree of automation.

[0013] Furthermore, a soft layer is provided on the circumference of the roller to increase the friction between the roller and the brick.

[0014] Furthermore, an ultrasonic measuring instrument for measuring the thickness of bricks is provided on the inner side of the support rod. The ultrasonic measuring instrument includes a transmitter and a receiver, which are symmetrically arranged on the inner wall of the support rod.

[0015] The beneficial effects of the present invention are as follows: the first conveying mechanism conveys the bricks to the second conveying mechanism, the second conveying mechanism stands the bricks upright, the orientation component unifies the side orientation of all the bricks, and the bricks are then conveyed to the screening mechanism. When the bricks pass through the opening, the complete bricks pass directly horizontally through the opening under the pressure of the rotating shaft, while the incomplete bricks fall directly from the opening because they are not subjected to the pressure of the rotating shaft, thereby screening out the complete bricks.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1 to 5 As shown

[0024] A construction waste brick screening and recycling device with detection function includes a first conveying mechanism 1, a second conveying mechanism 2, a directional component 3, and a screening mechanism 4. The first conveying mechanism 1 is a horizontal conveying mechanism, which can be a plate conveyor or a roller conveyor. The first conveying mechanism 1 is equipped with a drive motor for the operation of the whole machine. The second conveying mechanism 2 is installed at the outlet of the first conveying mechanism 1. The second conveying mechanism 2 is a roller conveyor. The inlet of the second conveying mechanism 2 is flush with the outlet of the first conveying mechanism 1 and is set horizontally. The inlet of the second conveying mechanism 2 is higher than the outlet and is set at an angle. The outlet end of the second conveying mechanism 2 is set vertically on both sides. The two sides of the second conveying mechanism 2 can be a straight structure or an arc structure. When the brick enters the inlet of the second conveying mechanism 2, the brick is in a flat state. Under the conveying action of the second conveying mechanism 2, the brick moves forward along the conveying plane. As the second conveying mechanism 2 changes from a horizontal state at the inlet end to a vertical state at the outlet end, the brick also becomes vertical under the drive of the second conveying mechanism 2.

[0025] The second conveying mechanism 2 has grooves on both sides of its upper surface. The grooves are always aligned with the upper surface of the second conveying mechanism 2. Rollers are installed inside the grooves and can rotate. The width of the grooves is equal to the height of the brick when it is laid flat, with an error not exceeding 3mm. The brick slides into the grooves under its own weight and moves forward under the drive of the rollers, transmitting the brick to the directional component. The directional component 3 is installed at the outlet of the second conveying mechanism 2. The directional component 3 has a frame structure, and the height of its inner frame is equal to the width of the brick when it is laid flat. When the brick is laid flat, its length is greater than its width, and its width is greater than its height. Under the action of the second conveying mechanism 2, the brick is vertically... When the brick is erected, there are two states where the brick stands upright: one is with the side formed by the length and height of the brick when it is laid flat as the bottom surface, and the other is with the side formed by the width and height of the brick when it is laid flat as the bottom surface. The brick continues to pass through the directional component 3 along the chute under the transmission of the second conveying mechanism 2. Since the height of the inner frame of the directional component 3 is equal to the width of the brick when it is laid flat, only the brick that stands upright with the side formed by the length and height of the brick when it is laid flat as the bottom surface can pass through the directional component 3. The brick in the other state will be pushed down by the directional component 3 and become the first state, thus passing through the directional component 3 and being conveyed to the screening mechanism 4.

[0026] The screening mechanism 4 is installed at the outlet of the directional component 3. The screening mechanism 4 is a roller conveyor with an opening 5. The front and rear of the opening 5 are connected by telescopic rods, and the length of the opening 5 can be adjusted according to the size of the brick, making it more applicable. The conveying plane of the screening mechanism 4 is flush with the inner bottom surface of the directional component 3. It also includes support rods 6 set on both sides of the front and rear ends of the opening 5. There can be multiple support rods 6. The support rods 6 are evenly distributed and fixedly connected to the side wall of the screening mechanism 4. The top of the support rods 6 at the same end are connected by a rotating shaft 7. The rotating shafts 7 at both ends are symmetrically arranged. The rotating shafts 7 are rotatably connected to the support rods 6. The rotating shafts 7 can rotate along the axis. The vertical height of the rotating shaft 7 away from the opening 5 is equal to the width of the brick when it is laid flat, which can accommodate the whole brick to pass through. When the brick passes through the rotating shaft 7, the brick will be pressed onto the screening mechanism 4 by the rotating shaft 7. The rotating shaft 7 pressing down on either end of the brick can make the brick suspend in the air.

[0027] The bricks are conveyed to the opening 5 on the screening mechanism 4. The bricks are first pressed onto the conveyor belt by the rotating shaft 7 at the front end of the opening 5. Driven by the conveyor belt, the bricks continue to move forward. When the middle part of the brick passes the rotating shaft 7, due to gravity, the front end of the brick tilts downward and the rear end of the brick rises. When it encounters a brick with a broken rear end, the brick will fall out of the opening 5. However, when it encounters a complete brick, the rear end of the brick will be pressed onto the conveyor belt by the rotating shaft 7. Driven by the conveyor belt, the brick continues to move forward to the other end of the opening 5. The brick is placed horizontally on the opening 5. The conveyor belt continues to move the brick forward. The front end of the brick is pressed down by the rotating shaft 7 at the rear end of the opening 5. When the rear end of the brick leaves the rotating shaft 7 at the front end of the opening 5, if the front end of the brick is broken, the brick will fall out of the opening 5. However, if the brick is complete, it will be pressed down by the rotating shaft 7, and the rear end of the brick will be suspended in the air. Driven by the conveyor belt, the brick continues to move, thus screening out the complete bricks and realizing the automatic screening function.

[0028] Specifically, the directional component 3 is equipped with grinding wheels 8 at both the top and bottom, and the distance between the two grinding wheels 8 is equal to the height of the inner frame of the directional component 3. The outer contours of the two grinding wheels 8 are flush with the inner contours of the directional component 3, and the grinding wheels 8 are connected by a belt. The grinding wheel 8 at the bottom of the directional component 3 is connected to a motor, and the grinding wheel 8 rotates under the drive of the motor, thereby grinding the concrete adhering to the brick.

[0029] Specifically, support rod 6 is a height-adjustable telescopic rod, which facilitates the selection of bricks of different sizes.

[0030] Specifically, a cleaning mechanism 9 is provided at the opening 5. The cleaning mechanism 9 includes a base plate 10, a laser sensor 11, and an electrically controlled telescopic rod 12. The base plate 10 is slidably connected to the inner wall of the opening 5. The laser sensor 11 and the electrically controlled telescopic rod 12 are both installed on the inward-facing side of the base plate 10. The extension and retraction of the electrically controlled telescopic rod 12 is controlled by the laser sensor 11. The laser sensor 11 is used to detect whether there are bricks stuck at the opening 5. When the laser sensor 11 detects that there are bricks at the opening 5 and the bricks remain there for a long time, the laser sensor 11 controls the electrically controlled telescopic rod 12 to extend and retract once. The retention time is set to the time required for two bricks to completely pass through the opening 5, thereby clearing the waste bricks stuck in the opening 5 and ensuring the continuous operation of the equipment.

[0031] Specifically, the electrically controlled telescopic rod 12 is installed at both ends of the base plate 10. The position of the electrically controlled telescopic rod 12 pushing the bricks at both ends facilitates the bricks falling. If the middle position of the bricks is pushed, the bricks may only move forward and not fall, thus improving the reliability of cleaning up waste bricks.

[0032] Specifically, the outlet of the screening mechanism 4 is equipped with a container 13 for collecting bricks, which facilitates the collection of intact bricks.

[0033] Specifically, a crusher 14 for crushing waste bricks is provided at the bottom of the opening 5. Waste bricks fall directly into the crusher 14 from the opening 5 and are crushed directly.

[0034] Specifically, the first conveying mechanism 1 is a vibrating transmission belt. The vibrating design facilitates the pre-leveling of bricks on the conveyor belt, avoiding manual leveling operations and improving the automation level of the equipment.

[0035] Specifically, a soft layer is provided on the circumference of the roller. The soft layer is used to increase the friction between the roller and the brick, prevent slippage between the roller and the brick, and ensure that the roller can move the brick forward.

[0036] Specifically, an ultrasonic measuring instrument for measuring the thickness of bricks is provided on the inner side of the support rod 6. The ultrasonic measuring instrument includes a transmitter and a receiver, which are symmetrically arranged on the inner sidewalls of the two support rods 6. When a brick passes between the transmitter and the receiver, the transmitter emits ultrasonic waves that pass through the brick, and the receiver receives the sound waves emitted by the transmitter. The receiver displays the thickness of the brick by measuring the intensity of the received sound waves.

[0037] The method of using this invention is as follows: Place the bricks on the first conveying mechanism 1. The first conveying mechanism 1 automatically conveys the bricks to the second conveying mechanism 2. The second conveying mechanism 2 stands the bricks upright. The orientation component 3 unifies the vertical direction of the bricks. The bricks are then conveyed to the screening mechanism 4. When the bricks pass through the opening 5, the complete bricks are directly suspended in the air under the pressure of the rotating shaft 7. The bricks pass horizontally through the opening 5. The incomplete bricks fall directly from the opening 5 because they are not subjected to the pressure of the rotating shaft 7. Thus, the function of screening complete bricks can be realized.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
