Description

Technical Field

[0001] The utility model relates to the technical field of concrete recycling, in particular to a slurry water recycling device for a concrete mixing station. Background Art

[0002] The concrete mixing station is mainly composed of five systems, namely the main machine, material weighing system, material conveying system, material storage system and control system, as well as other ancillary facilities. After transporting concrete, the concrete mixer truck and transport truck need to be flushed inside the mixing station. The slurry obtained by flushing is highly alkaline, which will pollute the environment if discharged at will; in addition, the flushing slurry contains concrete aggregates, which can be recycled.

[0003] The patent with announcement number discloses "a slurry water recovery device for a concrete mixing station, which relates to the field of concrete mixing stations and includes a recovery box, and both sides of the upper end of the recovery box are fixedly connected with mounting plates. The utility model is provided with a driving motor and a baffle on two mounting plates respectively. The cam on the driving motor and the reset spring on the baffle cooperate to drive the recovery plate to swing back and forth, thereby achieving a vibration effect, and being able to fully and quickly separate the aggregates in the slurry water, and at the same time being able to quickly shake off the fine aggregates into the collection box, thereby improving the working efficiency of the device."

[0004] Regarding the above-mentioned related technologies, the inventors believe that in actual use, aggregates are prone to block the holes of the filter plate. With long-term use, aggregates may block a large area of ​​the filter plate, thereby reducing the filtering and separation effect of the filter plate on the slurry water, and therefore needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a slurry water recovery device for a concrete mixing station. The specific technical scheme is as follows:

[0006] A slurry water recovery device for a concrete mixing station comprises a recovery box and an aggregate collection box fixedly arranged on one side of the recovery box, wherein a filter plate is rotatably arranged on the top of one end of the recovery box close to the aggregate collection box;

[0007] The inner wall of the recovery box is rotatably provided with a multi-stage electric push rod, the top of the output end of the multi-stage electric push rod is fixed with a reset spring, the top of the reset spring is fixed with a rotating seat, and the rotating seat is rotatably provided in the middle of the bottom surface of the filter plate;

[0008] A top pressing mechanism for colliding with the rotating rear filter plate is provided on one side of the top of the aggregate collecting box.

[0009] By adopting the above technical solution, the multi-stage electric push rod will rotate the filter plate after extension and retraction, and the pressing mechanism can collide with the rotated filter plate. The aggregates blocking the filter plate can be shaken off through repeated collisions, thereby clearing a large area of ​​the filter plate.

[0010] Optionally, the bottom of the filter plate is in cooperation and abutment with the top of the recovery box, the filter plate is inclined, and a U-shaped baffle is fixedly provided at the edge of one end of the filter plate away from the aggregate collection box, and the pressing mechanism includes a top rod fixedly provided at the top of one end of the aggregate collection box away from the recovery box and inclined, and a rubber pad fixedly provided at the top of the top rod.

[0011] By adopting the above technical solution, the U-shaped baffle can cover the top three sides of the filter plate, and with the inclination of the filter plate, the slurry after flushing in the concrete mixing station poured on the top of the filter plate can stay at the end of the filter plate away from the aggregate collection box.

[0012] Optionally, a water pump is fixedly provided at the bottom of the inner wall of the recycling box, a drainage pipe is fixedly provided at the output end of the water pump, and one end of the drainage pipe penetrates and extends to the outside of the recycling box. A box door is movably provided at one side of the inner wall of the aggregate collection box, and a handle is fixedly provided on the outer wall of the box door.

[0013] By adopting the above technical solution, people can open the box door by the handle to take out the aggregates centrally stored in the aggregate collection box.

[0014] Optionally, a reinforcing plate is fixed between the bottom of the recovery box and the aggregate collection box, a vibration motor is fixed at the bottom of the reinforcing plate, a plurality of damping spring shock absorbers are fixed at the bottom edges of the recovery box and the aggregate collection box, and a bottom plate is fixed at the bottom of the damping spring shock absorber.

[0015] By adopting the above technical solution, the separation rate of the filter plate for slurry and water can be improved through the vibration of the vibration motor, and the damping spring shock absorber can reduce the impact of the vibration of the recovery box and other components on the ground.

[0016] In summary, the present invention has at least one of the following beneficial effects:

[0017] 1. The water and aggregate in the slurry can be separated by the filter plate. The separated water and aggregate can be recycled and reused. The recycled aggregate can be used as the raw material of recycled concrete. The multi-stage electric push rod will rotate the filter plate after extension and retraction, so that the filter plate can pour the top aggregate into the aggregate collection box for centralized storage after rotation, and the top pressure mechanism can collide with the rotating filter plate. Through repeated collisions, the aggregate blocked in the filter plate can be shaken off, thereby dredging a large area in the filter plate and improving the filtering and separation effect of the filter plate on the slurry.

[0018] 2. The vibration of the vibration motor can increase the separation rate of the filter plate from the slurry and water. The buffering of the reset spring can reduce the impact of the filter plate colliding with the top pressure mechanism on the multi-stage electric push rod. The soft protection of the rubber pad makes it difficult for the outer surface of the filter plate to be scratched by the top pressure mechanism during collision. The damping spring shock absorber can reduce the impact of the vibration of the recovery box and other components on the ground. BRIEF DESCRIPTION OF THE DRAWINGS

The U-shaped baffle 31 can cover the three sides of the top of the filter plate 3. With the inclination of the filter plate 3, the slurry water after flushing in the concrete mixing station poured on the top of the filter plate 3 can stay at the end of the filter plate 3 away from the aggregate collection box 2, so that the slurry water on the filter plate 3 is not easy to flow into the aggregate collection box 2.

At this time, the filter plate 3 is repeatedly extended and retracted to make the filter plate 3 repeatedly collide with the top pressing mechanism, and the aggregate blocked in the filter plate 3 is shaken off and shaken off, thereby clearing a large area of ​​the filter plate 3.
