Description

Technical Field

[0001] This invention relates to the technical field of construction solid waste sorting, and more specifically, to equipment for sorting bricks and concrete blocks. Background Technology

[0002] Construction solid waste generally refers to solid waste generated during the construction, renovation, expansion, or demolition of buildings.

[0003] In recent years, with the rapid development of urban renewal and the construction industry in my country, a large amount of construction waste (solid waste) has been generated during the demolition and construction of buildings. Recycling is an effective way to treat construction solid waste, thus promoting the application of crushing systems in the field of construction solid waste recycling. Concrete blocks, bricks, mortar, and slag in construction solid waste can be recycled into usable aggregates through crushing systems. Classifying, and even finely classifying, construction solid waste for reuse is a feasible approach, but without intelligent sorting technology, it will incur significant costs. This presents a challenge to the large-scale promotion of the classification and reuse of construction solid waste. Further classification of construction solid waste reveals that it is relatively easy to extract steel bars / concrete blocks, bricks / concrete blocks, etc., manually.

[0004] However, sorting bricks and concrete blocks manually is inefficient and labor-intensive. Summary of the Invention

[0005] The purpose of this invention is to provide a brick and concrete block sorting device, which aims to solve the problem of low sorting efficiency of bricks and concrete blocks in construction solid waste in the prior art.

[0006] The present invention is implemented as follows: a brick and concrete block sorting device includes a primary conveyor belt for transporting blocky solid waste and a secondary conveyor belt for transporting concrete blocks. The blocky solid waste includes bricks and concrete blocks. The secondary conveyor belt is arranged in a staggered manner with the primary conveyor belt, and the secondary conveyor belt is located below the primary conveyor belt. The front end of the primary conveyor belt and the rear end of the secondary conveyor belt are stacked vertically in a staggered manner. There is a material dropping area between the front end of the primary conveyor belt and the rear end of the secondary conveyor belt for the blocky solid waste to fall from top to bottom.

[0007] A blower is provided in front of the material dropping area to blow out pulsed airflow toward the material dropping area. The blower extends laterally along the material dropping area and is connected to the air gun. The bottom of the blower has a guide plate that swings up and down elastically. The guide plate guides the airflow toward the material dropping area and blows it out at an upward angle. The airflow impacts the brick blocks of solid waste in the material dropping area, causing the brick blocks to deviate from the secondary conveyor belt and fall onto the secondary conveyor belt.

[0008] Furthermore, a plurality of blowing ports are provided in front of the material dropping area, and the plurality of blowing ports are arranged sequentially at intervals along the height direction of the material dropping area.

[0009] Furthermore, the front end of the guide plate is hinged, the rear end of the guide plate extends rearward, the bottom of the guide plate is provided with an elastic layer, the bottom of the elastic layer is fixedly arranged, and the top of the elastic layer is fixedly connected to the bottom of the guide plate.

[0010] When no airflow is blown out of the blowing port, the guide plate is tilted upwards. When airflow is blown out of the blowing port, the elastic layer changes its elastic compression according to the size of the airflow, thereby changing the tilt angle of the guide plate.

[0011] Furthermore, the rear end of the guide plate extends to a horizontal plate, and the top of the horizontal plate is provided with a plurality of horizontally arranged guide grooves. The front end of the guide groove is connected to the blowing port, and the rear end of the guide groove is connected to the dropping area.

[0012] Furthermore, a material discharge channel arranged from top to bottom is provided behind the secondary conveyor belt. The upper end of the material discharge channel has a feeding port for bricks in the material discharge area to enter, and the rear end of the material discharge channel has a discharging port for bricks in the material discharge channel to exit. The feeding port is arranged from back to front towards the rear of the material discharge area.

[0013] Furthermore, the material discharge channel is arranged in a curved shape, and the discharge port is arranged downwards.

[0014] Furthermore, the bottom of the material discharge channel has a bottom wall, which is arranged inclined downwards along the top-to-bottom direction of the material discharge channel, and the middle part of the bottom wall is arranged to bend upwards.

[0015] Furthermore, the material discharge channel is provided with multiple air intakes in the middle, and the air intakes are connected to the air intake device; the air intakes are arranged from bottom to top toward the material feed port, and the multiple air intakes are arranged circumferentially around the material discharge channel.

[0016] Furthermore, the inner wall of the material discharge channel is provided with a protective ring plate, which is arranged around the circumference of the material discharge channel and is located above the air intake. The outer end of the protective ring plate is connected to the inner wall of the material discharge channel, and the inner end of the protective ring plate extends toward the middle of the material discharge channel. Along the direction from the outside to the inside of the protective ring plate, the protective ring plate is arranged at a downward angle.

[0017] Furthermore, the lower part of the material discharge channel is provided with a plurality of fan-shaped elastic sheets, which are located below the protective ring sheet; the outer end of the elastic sheet is abutted on the protective ring sheet, and the inner end of the elastic sheet extends toward the center of the material discharge channel; the plurality of elastic sheets are arranged around the circumference of the material discharge channel.

[0018] When the multiple elastic sheets are in their natural state, the sides of the multiple elastic sheets abut against each other in sequence, and the multiple elastic sheets separate the upper and lower parts of the material drop channel; when the brick impacts the elastic sheets downward along the material drop channel, the elastic sheets bend and deform downward, the material drop channel is opened, and the brick falls from the discharge port.

[0019] Compared with the prior art, the brick and concrete block sorting equipment provided by the present invention allows the material discharge area formed between the primary and secondary conveyor belts to separate the bricks from the block solid waste by blowing out pulsed airflow from the blowing port. The guide plate that swings up and down elastically increases the range of the blowing airflow to the material discharge area, thus solving the problem of low sorting efficiency of bricks and concrete blocks in construction solid waste.

[0029] Reference Figure 1-5 The image shows a preferred embodiment of the present invention.

[0030] A brick and concrete block sorting device includes a primary conveyor belt 100 for conveying lumpy solid waste and a secondary conveyor belt 200 for conveying concrete blocks. The lumpy solid waste includes bricks and concrete blocks. The secondary conveyor belt 200 is arranged in a staggered manner with the primary conveyor belt 100. The secondary conveyor belt 200 is located below the primary conveyor belt 100. The front end of the primary conveyor belt 100 and the rear end of the secondary conveyor belt 200 are staggered and overlapped. There is a material dropping area between the front end of the primary conveyor belt 100 and the rear end of the secondary conveyor belt 200 for the lumpy solid waste to fall from top to bottom.

[0031] A blower 300 is provided in front of the material dropping area, which blows a pulsed airflow toward the material dropping area. The blower 300 is arranged along the lateral extension of the material dropping area and is connected to the air gun. The bottom of the blower 300 has a guide plate 301 that swings up and down elastically. The guide plate 301 guides the airflow toward the material dropping area and blows it out at an upward angle. The airflow impacts the bricks of block solid waste in the material dropping area, causing the bricks to deviate from the secondary conveyor belt 200 and fall. The concrete blocks fall onto the secondary conveyor belt 200.

[0032] The brick and concrete block sorting equipment provided above uses the material drop area formed between the primary conveyor belt 100 and the secondary conveyor belt 200 to allow the blowing port 300 to separate the bricks from the blocky solid waste by blowing out pulsed airflow. The guide plate 301, which swings up and down elastically, increases the range of the blowing airflow to the material drop area, thus solving the problem of low sorting efficiency of bricks and concrete blocks in construction solid waste.

[0033] Multiple blowing ports 300 are provided in front of the material discharge area. The multiple blowing ports 300 are arranged in sequence at intervals along the height direction of the material discharge area. Since the weight of bricks in block solid waste is lighter than that of concrete blocks in block solid waste, setting up multiple blowing ports 300 can more accurately and automatically separate bricks from block solid waste, thereby improving sorting efficiency.

[0034] In this embodiment, the front end of the guide plate 301 is hinged, the rear end of the guide plate 301 extends rearward, the bottom of the guide plate 301 is provided with an elastic layer 302, the bottom of the elastic layer 302 is fixedly arranged, and the top of the elastic layer 302 is fixedly connected to the bottom of the guide plate 301.

[0035] When no material flow is blown out of the blowing port 300, the guide plate 301 is tilted upwards. When material flow is blown out of the blowing port 300, the elastic layer 302 changes its elastic compression according to the size of the material flow, thereby changing the tilt angle of the guide plate 301.

[0036] The air guide plate concentrates the pulsed airflow to the material dropping area, avoiding the airflow from doing ineffective work. The elastic layer 302 changes the tilt angle of the guide plate 301 so that the airflow blown out of the air outlet 300 can flow up and down, increasing the airflow range of the material dropping area and thus improving work efficiency.

[0037] The rear end of the guide plate 301 extends to a horizontal plate 303. The top of the horizontal plate 303 is provided with a plurality of horizontally arranged guide grooves 304. The front end of the guide grooves 304 is connected to the blowing port 300, and the rear end of the guide grooves 304 is connected to the dropping area. In this way, the blowing airflow can be concentrated to flow in one direction through the horizontal plate 303 and the guide grooves 304, so as to increase the airflow intensity of the blowing airflow.

[0038] In this embodiment, a material discharge channel 400 arranged from top to bottom is provided behind the secondary conveyor belt 200. The upper end of the material discharge channel 400 has a feeding port 401 for bricks in the material discharge area to enter, and the rear end of the material discharge channel 400 has a discharging port 402 for bricks in the material discharge channel 400 to be discharged. The feeding port 401 is arranged from back to front towards the rear of the material discharge area.

[0039] The material drop channel 400 can increase the guiding and conveying of bricks when they fall, prevent bricks from being stuck randomly, and also buffer the falling bricks.

[0040] The material discharge channel 400 is arranged in a curved shape, and the discharge port 402 is arranged downwards; in this way, the bricks can be stably slid down into the set position within the material discharge channel 400.

[0041] The bottom of the material discharge channel 400 has a bottom wall 403. Along the top-to-bottom direction of the material discharge channel 400, the bottom wall 403 is arranged at an angle downwards, and the middle part of the bottom wall 403 is arranged to bend upwards; so that the bricks have a buffer contact surface, allowing the bricks to slide smoothly out of the material discharge channel 400 along the bottom wall 403.

[0042] The material discharge channel 400 is provided with multiple air intakes 404 in the middle, and the air intakes 404 are connected to the air intake device. The air intakes 404 are arranged from bottom to top toward the feed inlet 401, and the multiple air intakes 404 are arranged circumferentially around the material discharge channel 400. In this way, the air intakes 404 generate suction through the air intake device, which in turn makes the feed inlet 401 of the material discharge channel 400 have suction, so that the bricks are more easily sucked into the material discharge channel 400.

[0043] In this embodiment, a protective ring plate 405 is provided on the inner sidewall of the material discharge channel 400. The protective ring plate 405 is arranged around the circumference of the material discharge channel 400 and is located above the air intake 404. The outer end of the protective ring plate 405 is connected to the inner sidewall of the material discharge channel 400, and the inner end of the protective ring plate 405 extends toward the middle of the material discharge channel 400. Along the direction from the outside to the inside of the protective ring plate 405, the protective ring plate 405 is arranged inclined downwards.

[0044] The material discharge channel 400 can protect the air intake 404 through the protective ring plate 405, preventing bricks from blocking or damaging the air intake 404 after falling into the material discharge channel 400, and also playing a buffering role when bricks fall.

[0045] In this embodiment, the lower part of the material discharge channel 400 is provided with a plurality of fan-shaped elastic sheets 406, which are located below the protective ring sheet 405. The outer end of the elastic sheet 406 is connected to the protective ring sheet 405, and the inner end of the elastic sheet 406 extends toward the center of the material discharge channel 400. The plurality of elastic sheets 406 are arranged around the circumference of the material discharge channel 400.

[0046] When the multiple elastic plates 406 are in their natural state, the sides of the multiple elastic plates 406 abut against each other in sequence, and the multiple elastic plates 406 separate the upper and lower parts of the material drop channel 400; when the brick impacts the elastic plate 406 downward along the material drop channel 400, the elastic plate 406 bends and deforms downward, the material drop channel 400 is opened, and the brick falls from the discharge port 402.

[0047] When multiple elastic plates 406 divide the material drop channel 400 vertically, the air pressure in the material drop channel 400 decreases under the suction action of the air intake 404, which makes it easier for bricks in the material drop area to deviate from the secondary conveyor belt 200 and enter the material drop channel 400, and also plays a buffering role when bricks fall.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
