Description

Technical Field

[0001] This utility model relates to the field of construction waste recycling technology, specifically a sorting device for the secondary utilization of construction waste. Background Technology

[0002] Construction waste is a general term for engineering spoil, engineering mud, engineering waste, demolition waste, and decoration waste. It includes the excavated soil, materials, and other waste generated during the construction, expansion, renovation, and demolition of various buildings, structures, pipelines, etc., as well as during the decoration and renovation of houses by residents. It does not include construction waste that has been inspected and identified as hazardous waste. With the acceleration of industrialization and urbanization, the construction industry has also developed rapidly, and the amount of construction waste generated is increasing day by day.

[0003] For example, patent document CN 220004327 U discloses a sorting device for the secondary utilization of construction waste. This device includes a box with a conveyor belt inside and sorting components inside. Two motors are fixedly connected to the outside of the box, and crushing rollers are fixedly connected to the output ends of the motors. The crushing rollers have crushing teeth on their outer sides. A feeding component is located on the top of the box, and a crushing component is located above the crushing rollers. This invention solves the problems of existing devices that use conveyor belts and permanent magnet adsorption devices to sort metals in waste. However, these devices are inconvenient to discharge after the permanent magnet adsorption device adsorbs the metal waste, and the water mist sprayed from the dust suppression spray pipe can corrode the metal. Furthermore, the mud and sludge formed by the water mist mixing with the slag can pollute the working environment, making them inconvenient to use.

[0004] However, in actual use, this structure often only uses simple magnetic attraction to sort magnetically attracted metal construction waste. However, the magnetically attracted metal construction waste cannot make sufficient contact with the magnetic components, which easily leads to incomplete sorting. At the same time, the equipment cannot remove dust during the sorting process of construction waste, and cannot meet the needs of daily use. Therefore, it is urgent to design a sorting device for the secondary utilization of construction waste to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a sorting device for the secondary utilization of construction waste, in order to solve the problem mentioned in the background art that the existing structure can only use simple magnetic attraction of construction waste in actual use to sort magnetically attracted metal construction waste. However, the magnetically attracted metal construction waste cannot make sufficient contact with the magnetic attraction component, which easily leads to incomplete sorting. At the same time, the device cannot remove dust during the sorting and processing of construction waste, and cannot meet the needs of daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sorting device for the secondary utilization of construction waste, including a separation frame, a feeding trough at one end of the surface of the separation frame, a top frame on the surface of the separation frame, a first conveyor belt on the inner bottom wall of the separation frame, and an installation plate fixedly connected to the bottom end of the separation frame;

[0007] A first dust collector and a second dust collector are fixedly connected to one end of the separation frame, and a second dust collector is fixedly connected to the other end of the separation frame. Dust collector side covers are fixedly connected to both sides of the first dust collector and the second dust collector.

[0008] Preferably, a movable cover is fixedly connected to one end of the first and second vacuum cleaners that are far apart from each other, and a plug-in socket is movably connected to one end of the movable cover.

[0009] Preferably, the movable cover has an insertion slot inside, and the edge of the movable cover is provided with a magnetic ring.

[0010] Preferably, a first recycling bin is fixedly connected to one end of the mounting plate, and a second recycling bin is fixedly connected to the other end of the mounting plate.

[0011] Preferably, a second conveyor belt is provided at the bottom of the top frame, and a magnetic strip is provided on the surface of the second conveyor belt.

[0012] Preferably, a limit cover is fixedly connected to one end of the top frame, and a scraper strip is provided at the bottom of the limit cover.

[0013] Preferably, the inner walls of the separation frame are provided with dust-collecting grid grooves on both sides.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This construction waste recycling sorting device, through its separation frame, feeding chute, top frame, first conveyor belt, mounting plate, first recycling bin, second recycling bin, second conveyor belt, magnetic belt, limiting cover, and scraper, enables the equipment to continuously and stably separate magnetically adsorbable metals during the sorting of construction waste for recycling. In actual use, the operator first introduces the construction waste into the feeding chute at one end of the separation frame, and then simultaneously starts the first conveyor belt on the bottom wall of the separation frame and the second conveyor belt inside the top frame. The first conveyor belt transports the surface construction waste. When the construction waste enters the bottom of the second conveyor belt, the magnetically adsorbable metals inside are evenly attracted by the magnetic belt at the bottom of the second conveyor belt, thus performing the sorting operation of the construction waste on the surface of the first conveyor belt for recycling. Then, the first conveyor belt sends the other construction waste into the second recycling bin. The magnetically adsorbable metals are transported along the second conveyor belt and finally scraped off by the scraper at the limiting cover, entering the first recycling bin for separation and recycling, demonstrating the practicality of the equipment design.

[0016] This construction waste recycling sorting device, through its separation frame, first and second dust-collecting fans, dust-collecting side covers, movable covers, connectors, connector slots, magnetic rings, and dust-collecting grid slots, further improves the overall efficiency of the equipment. During daily use, operators can activate the first and second dust-collecting fans at both ends of the separation frame to perform internal suction. This allows the dust-collecting side covers to continuously collect dust from the dust-collecting grid slots on both sides of the inner wall of the separation frame. Simultaneously, the collected dust flows through the movable covers into the connectors. The movable covers and connectors are quickly assembled and disassembled via connector slots and magnetic rings, facilitating dust disposal and demonstrating the comprehensive design of the equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A sorting device for the secondary utilization of construction waste includes a separating frame 1, a feeding trough 2 at one end of the surface of the separating frame 1, a top frame 3 on the surface of the separating frame 1, a first conveyor belt 4 on the inner bottom wall of the separating frame 1, a mounting plate 5 fixedly connected to the bottom end of the separating frame 1, a first recycling bin 13 fixedly connected to one end of the mounting plate 5, a second recycling bin 14 fixedly connected to the other end of the mounting plate 5, a second conveyor belt 15 at the bottom of the top frame 3, a magnetic belt 16 on the surface of the second conveyor belt 15, and a magnetic belt 16 fixedly connected to one end of the top frame 3. The limiting cover 17 has a scraper strip 18 at its bottom. The inner walls of the separating frame 1 have dust collection grid grooves 19 on both sides. The first conveyor belt 4 on the bottom wall of the separating frame 1 and the second conveyor belt 15 inside the top frame 3 are started simultaneously. The first conveyor belt 4 transports the construction waste on the surface. When the construction waste enters the bottom of the second conveyor belt 15, the magnetic metal inside can be evenly connected and magnetically attracted by the magnetic strip 16 at the bottom of the second conveyor belt 15, so as to carry out the secondary utilization and classification operation of the construction waste on the surface of the first conveyor belt 4.

[0026] A first vacuum cleaner 6 and a second vacuum cleaner 7 are fixedly connected to one end of the separating frame 1, and the second vacuum cleaner 7 is fixedly connected to the other end of the separating frame 1. Dust-collecting side covers 8 are fixedly connected to both sides of the first vacuum cleaner 6 and the second vacuum cleaner 7. A movable cover 9 is fixedly connected to the ends of the first vacuum cleaner 6 and the second vacuum cleaner 7 that are far apart from each other. A plug-in seat 10 is movably connected to one end of the movable cover 9. A plug-in slot 11 is opened inside the movable cover 9. A magnetic suction ring 12 is provided on the edge of the movable cover 9. When the first vacuum cleaner 6 and the second vacuum cleaner 7 at both ends of the separating frame 1 are started, they perform a suction operation inside, so that the dust-collecting side covers 8 on both sides can perform a continuous suction operation at the dust-collecting grid slots 19 on both sides of the inner wall of the separating frame 1.

[0027] Working Principle: During operation, the user first feeds the construction waste into the inlet chute 2 at one end of the separating frame 1. Then, the first conveyor belt 4 on the bottom wall of the separating frame 1 and the second conveyor belt 15 inside the top frame 3 are started simultaneously. The first conveyor belt 4 transports the surface construction waste. When the construction waste enters the bottom of the second conveyor belt 15, the magnetically attractable metal inside is evenly attracted by the magnetic strip 16 at the bottom of the second conveyor belt 15, performing a sorting operation for the secondary utilization of the construction waste on the surface of the first conveyor belt 4. Then, the first conveyor belt 4 sends the remaining construction waste into the second recycling bin 14, and the magnetically attractable metal is transported along the second conveyor belt 15. Finally... The material is scraped off at the scraper strip 18 of the limiting cover 17 and enters the first recycling bin 13 for separation and recycling. During daily use, the staff can start the first vacuum fan 6 and the second vacuum fan 7 at both ends of the separating frame 1 to perform suction operation. This allows the side vacuum covers 8 on both sides to continuously perform vacuuming operation at the vacuum grid grooves 19 on both sides of the inner wall of the separating frame 1. At the same time, the sucked-out dust can eventually enter the interior of the plug-in seat 10 along their respective movable covers 9. The movable covers 9 and the plug-in seat 10 can be quickly disassembled and assembled through the plug-in groove 11 and the magnetic ring 12, which facilitates the handling of dust. The above is the complete working principle of this utility model.
