Description

Technical Field

[0001] This utility model relates to the field of construction waste recycling and treatment technology, and in particular to a combined construction waste treatment production line. Background Technology

[0002] Currently, the traditional methods of disposal are mainly landfill and pile-up. In economically developed areas, there are construction waste production lines, but the production line technology is simple, the air separation effect is relatively poor, the impurity content of recycled aggregate is high, and the produced aggregate is continued to be used in landfill.

[0003] Construction waste has a complex composition, mainly consisting of bricks, tiles, concrete blocks, gypsum board, wood, plastics, rubber, glass products, and other impurities. Current processing technologies include crushing before screening, screening before crushing, and separation without crushing. Conventional integrated equipment has the characteristics of large footprint, long installation, commissioning, and production cycles, and high civil engineering costs for customers. Utility Model Content

[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a modular construction waste processing production line. By setting up a classification production line, different impurity removal modules are set up according to the different mixed types of construction waste. The set-up slag tension screen classifies the construction waste raw materials into three levels and performs corresponding sorting and air separation on the three levels of aggregates. After classification, the aggregates are tested for metals according to their corresponding diameters to adsorb metal impurities mixed in with the construction waste. The production line equipment used in this invention is assembled from independent finished equipment, which reduces the basic design and manufacturing cycle, effectively controls equipment costs and the total project cost, and saves land area.

[0006] This utility model provides a combined construction waste treatment production line, including a feeding module configured as an inclined chain plate feeder, a grading and screening module located at the end of the feeding module, a transfer roller group located at the end of the grading and screening module, a magnetic separation module located at the front end of the transfer roller group, and an air separation and impurity removal module located on the side of the transfer roller group; the grading and screening module is a slag and soil tension screen, which is provided with at least two layers of screen mesh, which divides the slag and soil tension screen from top to bottom into a large aggregate layer, a medium aggregate layer, and a small aggregate slag and soil layer; the transfer roller group includes a second roller, the end of the medium aggregate layer is connected to the second roller, and the magnetic separation module is located at the front end of the second roller.

[0007] An inclined chain plate feeder is used to transport construction waste to the grading and screening module, achieving uniform and stable feeding. The feeding frequency can be adjusted in real time according to the production line. The tension screen consists of a dual vibration system composed of the linear vibration of the main screen body and the additional vibration of the floating screen frame, generating relative motion to realize the screening process. It separates low-purity construction waste into at least three groups according to different diameters, thus facilitating subsequent impurity removal steps based on different material diameters. The second roller belt is set up to transport and remove medium aggregates. The magnetic separation module is used to adsorb metal impurities in construction waste. The air separation module removes light impurities from the roller belt using air power. For specific details, the structure of the tension screen can be found in existing technology.

[0008] In some embodiments, the air separation and impurity removal module consists of several frequency converter blowers spaced at intervals, located on the side of the second roller belt. The frequency converter blowers are used to screen out lighter impurities on the roller belt, ensuring the cleanliness of the aggregate. Since the production line is relatively long, at least one frequency converter blower can be installed along the route to adapt to the structure of the production line for impurity removal.

[0009] In some embodiments, the transfer roller assembly further includes a first roller connected to the end of the large aggregate layer, and the air separation module is also provided on the side of the first roller. The first roller is used to transport aggregates with larger diameters, and the air separation module on the side is used to remove light impurities from the aggregates. The variable frequency blower can be installed on the side of the first and second rollers, or it can be independently mounted or fixed to a wall. The specific installation method can be adapted to the changes in the actual equipment structure, which will not be elaborated here. After air separation, the lighter impurities fall into the storage bin. The frequency and blowing angle of the blower are adjustable.

[0010] In some embodiments, manual picking platforms are spaced apart along the sides of the first conveyor belt. Each manual picking platform has a detachable sorting hopper. The air-separation module is located in front of the manual picking platform, and a magnetic separation module is also located at the end of the first conveyor belt, behind the manual picking platform. Large aggregates, due to their larger diameter, are easily identifiable by the naked eye; therefore, manual picking platforms are provided. During the conveying process, picking platforms are positioned along the sides, allowing workers to select impurities from the conveyor belt, thus improving the purity of the aggregates. Detachable sorting hoppers are provided to collect the impurities selected by the workers.

[0011] In some embodiments, the magnetic separation module includes a permanent magnet self-unloading separator and a turbine current box. The magnetic separation module is mounted above the first and second rollers and connected to both sides of the first and second rollers, respectively. The permanent magnet self-unloading separator, while keeping the main parameter IN that determines the separator's performance constant, increases the number of coil turns N and reduces the current density, thereby significantly reducing the heat generated by the coil. The main body adopts a fully sealed structure, suitable for use in outdoor and harsh environments. It employs a cycloidal pin reducer for belt drives, thus ensuring reliable operation, convenient adjustment, and simple maintenance. The specific structures of the permanent magnet self-unloading separator and the turbine current box can be found in existing technologies.

[0012] In some embodiments, the end of the small aggregate and slag layer is connected to a small aggregate single vibrating screen. The upper layer of the small aggregate single vibrating screen is the small aggregate layer, and the lower layer is the slag layer. The end of the small aggregate layer is connected to a ventilation separator to remove impurities. The small aggregate single vibrating screen is used to separate small aggregates and slag. Since the building materials have already undergone initial screening, the material entering the small aggregate and slag layer has a high purity. Therefore, it is screened by the single vibrating screen. The screened small aggregate is introduced into the air separator for air separation and impurity removal, while the screened slag is uniformly introduced into a storage bin for waste collection.

[0013] In some embodiments, a storage compartment is further included, which is disposed below the transfer roller assembly. An air pipe extends upward from the storage compartment and is located on the side of the first and second rollers and opposite the air separation and impurity removal module. The storage compartment, positioned below the rolling belt, can collect lightweight impurities while providing support for the rollers. The air pipe's inlet extends from the lower storage compartment to above the rollers, directly opposite the position of the variable frequency blower. When the variable frequency blower blows air to agitate impurities, the impurities fall into the lower storage compartment along the air pipe.

[0014] In some embodiments, a raw material processing area is also included, located at the front end of the feeding module. Construction waste raw materials must undergo pretreatment to remove large interfering items before entering the feeding module. Preferably, the processing method in the raw material processing area involves using an excavator to pick out large pieces of material from the construction waste, with the remaining suitable material entering the production line, thus avoiding damage to the grading and screening module from excessively large materials.

[0015] In some embodiments, the system further includes an aggregate bin, to which the first roller, the second roller, and the end of the air classifier are all connected. The aggregate bin is used to uniformly store the three sets of aggregates obtained after impurity removal, facilitating subsequent further refining and crushing steps.

[0016] In some embodiments, the screen mesh disposed on the top layer of the slag loosening screen is composed of spaced-apart grates, and the screen mesh disposed on the bottom layer of the slag loosening screen is a polyurethane loosening screen. The bottom screen mesh adopts a polyurethane loosening screen structure, which can screen viscous materials, while the upper layer adopts a grating structure, which can meet the aggregate impact requirements. Preferably, the slag loosening screen separates the material into slag with small aggregate of 0-10mm, medium aggregate of 10-50mm, and large aggregate greater than 50mm.

[0017] By adopting the above technical solution, the beneficial effects of this utility model are:

[0018] This invention utilizes a classification production line that incorporates different impurity removal modules based on the varying mixture types of construction waste. A slag and soil tension screen categorizes the construction waste into three grades, and the aggregates are then sorted and air-separated accordingly. After classification, the aggregates are tested for metals based on their diameter, adsorbing metallic impurities mixed in with the construction waste. The production line equipment used in this invention is assembled from independent finished products, reducing the design and manufacturing cycle, effectively controlling equipment and overall project costs, and saving floor space.
