Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of construction waste treatment equipment, specifically a construction waste recycling device with a filtration function. This device is mainly used in scenarios where construction waste is generated, such as construction sites and demolition sites. It can collect and transport construction waste, and simultaneously filter and separate liquids such as sewage and rainwater contained in the construction waste, preventing the indiscriminate discharge of liquids with the construction waste and causing environmental pollution. It also improves the convenience and efficiency of construction waste recycling and treatment, laying the foundation for subsequent classification, recycling, and reuse of construction waste. Background Technology
[0002] With the acceleration of urbanization, the number of construction projects and urban renewal projects has increased significantly, and the total amount of construction waste generated has also continued to rise. Construction waste not only includes solid waste such as concrete blocks, bricks, and sand, but also a large amount of sewage and rainwater during construction or after rain. These liquids are often mixed with pollutants such as mud, dust, and chemical residues.
[0003] Currently, construction waste is typically collected and transported using ordinary handcarts or open hoppers at construction sites. However, these traditional devices have significant drawbacks: First, they lack filtration capabilities, allowing liquids from the construction waste to leak through equipment gaps during transport, polluting the construction site, surrounding roads, and soil. This pollution is particularly pronounced during the rainy season or in construction scenarios involving wet operations, increasing cleaning and maintenance costs and potentially posing environmental compliance risks due to indiscriminate wastewater discharge. Second, traditional equipment requires separate collection of construction waste and liquid treatment, necessitating separate wastewater cleanup. This cumbersome process consumes considerable manpower and time, reducing construction efficiency. Third, while some construction waste recycling equipment attempts to incorporate filtration structures, the filter components are often fixed connections, making disassembly, cleaning, or replacement difficult. Prolonged use can lead to filter clogging, reducing filtration effectiveness. Furthermore, the equipment lacks overall flexibility, making it difficult to move within confined construction areas and meet the diverse needs of various construction scenarios.
[0004] In view of the shortcomings of the existing technology, there is an urgent need for a construction waste recycling device with efficient liquid filtration function, convenient operation, flexible mobility and easy maintenance of filter components, so as to solve the problem of simultaneous collection and transportation of construction waste and liquid separation, reduce the risk of environmental pollution and improve the operation efficiency of construction sites. Utility Model Content
[0005] The purpose of this invention is to provide a construction waste recycling device with a filtration function, thereby solving the problems mentioned in the background art, such as the lack of filtration function in traditional construction waste recycling equipment leading to liquid leakage and pollution, cumbersome and inefficient operation procedures, inconvenient maintenance of filter components, and poor equipment mobility. By optimizing the equipment structure design, the device achieves integrated operation of construction waste collection and liquid filtration separation, improving the practicality, convenience, and environmental friendliness of the equipment.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a construction waste recycling device with a filtration function, comprising a movable support, wherein a recycling hopper is provided on the movable support via a pair of bearing seats, a push handle is fixed to the side wall of the recycling hopper, the recycling hopper is configured with a bottom-opening structure, and a filtration assembly is provided at the bottom of the recycling hopper;
[0007] The filtrate assembly includes a U-shaped frame fixed at the bottom opening of the recovery hopper, a pair of T-shaped guide grooves are provided on the U-shaped frame, T-shaped guide blocks are slidably connected inside the two T-shaped guide grooves, a collection hopper is fixed between the two T-shaped guide blocks, a handle is fixed to the side wall of the collection hopper, and a filter screen is provided inside the collection hopper.
[0008] The T-shaped guide groove and the T-shaped guide block are connected by a limiting mechanism. The limiting mechanism includes a limiting hole opened on the T-shaped guide block and a sliding cavity opened on the U-shaped frame. A slider adapted to it is provided inside the sliding cavity. A limiting head is fixed at one end of the slider and a pull rod is fixed at the other end. A spring is sleeved on the pull rod inside the sliding cavity.
[0009] The filter screen is detachably connected to the inner wall of the collection hopper by bolts, and the mesh diameter of the filter screen is set to 2-5mm. The filter screen is made of stainless steel.
[0010] The end of the pull rod away from the slider extends to the outside of the U-shaped frame and is fixed with a pull ring. The outer peripheral wall of the pull ring is wrapped with a rubber anti-slip sleeve with a thickness of 3-5mm, and the outer surface of the rubber anti-slip sleeve is provided with a diamond-shaped anti-slip texture.
[0011] The bottom of the collection hopper is designed as a sloping structure tilted to one side at an angle of 10-15°. A drain port with an inner diameter of 15-20 mm is provided at the lowest point of the bottom of the collection hopper. The inner wall of the drain port is provided with internal threads. A sealing cap is connected to the drain port through the internal threads. A rubber sealing gasket is fixed to the top of the sealing cap.
[0012] The bottom four corners of the movable support are rotatably connected to casters via pivots. The rims of the casters are made of high-strength nylon, and each caster has a brake pad hinged to its side. The inner wall of the brake pad is provided with a wear-resistant rubber layer.
[0013] The push handle is configured as a U-shaped structure, and both ends of the push handle are fixed to the side wall of the recycling hopper by full welding. The outer peripheral wall of the push handle is wrapped with a sponge cushioning sleeve with a thickness of 8-10mm.
[0014] The connection between the U-shaped frame and the bottom opening of the recycling hopper is uniformly fixed with reinforcing ribs along the length of the U-shaped frame.
[0015] Working principle:
[0016] Equipment movement and positioning
[0017] In use, the operator can hold the push handle and push the entire device to the construction waste dumping location by moving the casters at the bottom of the support. The casters are made of high-strength nylon, which has good load-bearing capacity and wear resistance, and can adapt to the rough ground of the construction site. After the device is moved to the target position, press down on the brake pad on the side of each caster. The wear-resistant rubber layer on the inside of the brake pad makes close contact with the caster, and the device is fixed by friction, preventing the equipment from shifting during the loading of construction waste.
[0018] Construction waste collection and preliminary filtrate
[0019] Construction waste is directly loaded into the recycling hopper. Under gravity, the wastewater, rainwater, and other liquids contained within the waste flow through the bottom opening of the hopper into the filtration assembly below. First, the liquid enters the filter screen inside the collection hopper. The filter screen is made of 304 stainless steel, which is corrosion-resistant and high-strength. Its 2-5mm mesh diameter effectively intercepts solid particles such as small stones and debris from the construction waste, allowing only liquid to pass through the filter screen to the bottom of the collection hopper, achieving initial solid-liquid separation.
[0020] Storage and discharge of liquid in collection hopper
[0021] Liquid flowing through the filter screen into the bottom of the collection hopper is inclined at 10-15°, allowing it to automatically collect at the lowest point of the drain under gravity, facilitating centralized storage and discharge. During collection, the sealing cap at the drain is tightly connected via internal threads, and the rubber gasket on top effectively prevents leakage. When the liquid in the collection hopper reaches a certain level, the operator can unscrew the sealing cap and direct the liquid through the drain into a designated wastewater collection container, preventing indiscriminate discharge and pollution.
[0022] Maintenance and cleaning of filter components
[0023] After prolonged use, a large amount of solid impurities may accumulate on the surface of the filter screen, leading to a decrease in filtration efficiency. In this case, the filter screen needs to be cleaned or replaced.
[0024] First, the operator pulls the pull ring of the limiting mechanism outward. The pull ring drives the pull rod to move to the outside of the slide cavity. The pull rod pulls the slider to compress the spring. At the same time, the limiting head disengages from the limiting hole of the T-shaped guide block, releasing the limiting fixation between the T-shaped guide groove and the T-shaped guide block.
[0025] Next, hold the handle on the side wall of the collection hopper and pull the collection hopper outward along the T-shaped guide groove until the T-shaped guide block is completely separated from the T-shaped guide groove, thus separating the collection hopper from the U-shaped frame;
[0026] Finally, unscrew the bolts connecting the filter screen and the collection hopper to remove the filter screen for cleaning. If the filter screen is damaged, you can replace it with a new one. After maintenance, simply reverse the steps to put the collection hopper back in place.
[0027] Dumping and Transfer of Construction Waste
[0028] Once the recycling hopper is full of construction waste, the operator releases the brake pads on the casters and pushes the device to the designated construction waste disposal location. Since the recycling hopper is connected to the movable support through a bearing seat, it can rotate around the axis of the bearing seat. The operator can tilt the recycling hopper by pushing the handle to dump the construction waste inside to the designated location, making the operation convenient and labor-saving.
[0029] Compared with the prior art, the beneficial effects of this utility model are:
[0030] Integrated filtrate design with strong environmental protection: By setting a filtrate component at the bottom of the recycling hopper, the collection of construction waste and the separation of liquid filtration can be carried out simultaneously, effectively avoiding liquid leakage and pollution, meeting environmental protection requirements, and reducing environmental compliance risks at construction sites.
[0031] The filter assembly is detachable and easy to maintain: Utilizing the sliding cooperation of the T-shaped guide groove and T-shaped guide block, combined with the quick limiting and unlocking of the limiting mechanism, the collection hopper can be easily disassembled and installed, facilitating the cleaning and replacement of the filter screen and ensuring the filtrate efficiency during long-term use.

[0042] A construction waste recycling device with a filtration function.
[0043] This implementation plan addresses the technical problems existing in the prior art, as disclosed in the background section above: "Currently, construction sites typically use ordinary handcarts or open hoppers for collecting and transporting construction waste. However, these traditional devices have significant drawbacks: First, they lack filtration capabilities, allowing liquids from the construction waste to easily leak from equipment gaps during transport, polluting the construction site ground, surrounding roads, and soil. This pollution problem is particularly pronounced during the rainy season or in construction scenarios involving wet operations, not only increasing the cleaning and maintenance costs of the construction site but also potentially leading to environmental compliance risks due to the indiscriminate discharge of wastewater; Second, traditional equipment requires separate processing for the collection of construction waste and the treatment of liquids." The process involves first collecting construction waste, then separately cleaning the wastewater on site. This is cumbersome, consumes a lot of manpower and time, and reduces construction efficiency. Thirdly, while some construction waste recycling equipment attempts to add filtration structures, the filter components are mostly fixed connections, making them difficult to disassemble, clean, or replace. Long-term use easily leads to filter clogging, resulting in decreased filtration efficiency. Furthermore, the overall flexibility of the equipment is poor, making it inconvenient to move within narrow construction sites and unable to meet the diverse needs of different construction scenarios. In practical terms, this problem is clearly real and difficult to solve. Therefore, to address this technical issue, a construction waste recycling device with filtration function is provided.
