Description

Technical Field

[0001] This utility model belongs to the field of recycling devices, specifically relating to a device for recycling leftover concrete materials used in bridge construction. Background Technology

[0002] The concrete waste recycling device for bridge construction is a specialized piece of equipment for cleaning, screening, separating, and recycling concrete waste generated during bridge construction.

[0003] Existing devices lack dust collection measures during feeding and screening, causing concrete dry powder and cement particles to be easily stirred up, resulting in excessive dust concentration at the construction site. They also fail to cover the complex surfaces of materials, and soil residue leads to excessive mud content in recycled aggregates. Fixed nozzles require continuous high-pressure water spraying, resulting in low water resource utilization. Furthermore, sand, gravel, and cement lumps in the concrete residue are easily stuck in the pores of traditional fixed screens. Utility Model Content

[0004] To overcome the problems of existing devices lacking dust collection measures during feeding and screening, resulting in excessive dust concentration at construction sites due to the easy raising of concrete dry powder and cement particles, failure to cover complex material surfaces, excessive mud content in recycled aggregates due to soil residue, the need for continuous high-pressure water spraying from fixed nozzles leading to low water resource utilization, and the easy clogging of sand, gravel, and cement lumps in concrete residue into the gaps of traditional fixed screens, a concrete residue recycling device for bridge construction is proposed.

[0005] The technical solution of this utility model is as follows: a concrete waste recycling device for bridge construction, including a cleaning mechanism; a dust suction mechanism is provided on one side of the cleaning mechanism, and a screening mechanism is provided inside the cleaning mechanism; the cleaning mechanism includes a stop block, a first trough, a fixing block, a second trough, a motor, a rotating column, a water pipe, and a nozzle; the first trough is opened through one side of the stop block, and two fixing blocks are fixedly connected to one side of the stop block. The two fixing blocks are located on both sides of the first trough, and the second trough is opened at the end of the two fixing blocks that are close to each other. A motor is fixedly connected to the inner wall of one fixing block, and one end of the rotating column is fixedly connected to the output end of the motor. A water pipe is fixedly connected to the side wall of the rotating column, and the side wall of the water pipe is inside the first trough. A nozzle is fixedly connected to the end of the water pipe that is close to the stop block, and a pumping mechanism is fixedly connected to the other end of the water pipe.

[0006] Furthermore, the pumping mechanism includes a water pump, a water tank, and a third tank; the water tank is slidably installed on the side wall of the water pipe, and the third tank is opened through the upper end of the water tank. The side wall of the water pipe is attached to the inner wall of the third tank, and the other end of the water pipe is fixedly connected to the water pump.

[0007] Furthermore, the dust collection mechanism includes a fourth chamber, a fifth chamber, an F-shaped duct, an exhaust box, a sixth chamber, a fan, a seventh chamber, and a first filter. The fourth chamber is located on the other side of the block, and the fifth chamber is located on the other side of the block. The inner walls of the fourth and fifth chambers are jointly fixed to the side wall of the F-shaped duct. The exhaust box is slidably installed on the side wall of the F-shaped duct. The sixth chamber is located through the upper end of the exhaust box. The side wall of the F-shaped duct fits against the inner wall of the sixth chamber. The fan is fixed to the inner wall of the exhaust box. The seventh chamber is located on one side of the exhaust box, and the first filter is fixed to the inner wall of the seventh chamber.

[0008] Furthermore, the screening mechanism includes a feed block, a second filter screen, a discharge port, a collection box, and a water outlet; the upper end of the baffle is fixedly connected to the feed block, the inner wall of the baffle is fixedly connected to the second filter screen, the lower end of the baffle is fixedly connected to the discharge port, the lower part of the baffle is slidably installed with the collection box, and a water outlet is opened on one side of the collection box.

[0009] Furthermore, the second filter is located between the fourth and fifth tanks.

[0010] Furthermore, the fan surface is equipped with a protective mesh.

[0011] Furthermore, the second tank is located at the lower end of the second filter screen.

[0012] The beneficial effects of this utility model are as follows: By utilizing a negative pressure circuit, an airflow barrier is formed at the feed inlet, drawing dust into the exhaust box to prevent dust overflow. The spray nozzle can adjust the rinsing direction according to the material accumulation state. For example, vertically falling materials are rinsed from top to bottom, while flat materials are rinsed from the side. When the material clogs the second filter screen, the spray nozzle is turned to align with the filter screen holes, using high-pressure water flow to impact the blockage and achieve online unblocking. An inclined guide plate is set at the bottom of the collection box to ensure rapid flow of mud and water blocks, avoiding the retention and contamination of aggregates. This solves the problems of existing devices lacking dust collection measures during feeding and screening, making it easy for concrete dry powder and cement particles to be raised, resulting in excessive dust concentration at the construction site, inability to cover the complex surface of materials, and soil residue leading to excessive mud content in recycled aggregates. Fixed spray nozzles require continuous high-pressure water spraying, resulting in low water resource utilization. Sand, gravel, and cement lumps in the concrete residue are easily stuck in the gaps of traditional fixed screens. Attached Figure Description

[0028] Please see Figure 3 and Figure 6 In this embodiment, the second tank 14 is located at the lower end of the second filter screen 32, and the material and the second filter screen 32 can be rinsed by the nozzle 18.

[0029] Working principle: First, water is injected into the water tank 110. Then, the fan 26 is turned on, and the material is poured in from the top of the feed block 31.
