Description

Technical Field

[0002] Patent announcement number CN21599591 discloses a waste slurry water recycling system for a concrete mixing station, which relates to the field of waste slurry water collection, including a fixed box, the inner wall of the fixed box is provided with a guide plate, one side of the guide plate is movably provided with a movable plate, one side of the fixed box is provided with a first filter plate, one side of the fixed box is provided with a conveying channel, and one side of the conveying channel is provided with a sedimentation tank. The utility model passes the waste slurry water into a fixed box, and the waste slurry water moves downward along the guide plate, and the stones are blocked by the first filter plate, while the fine sand and waste water can enter the conveying channel and enter the sedimentation tank. As the water level in the sedimentation tank rises, under the action of the second filter plate, the filtered water rises to the top of the second filter plate, and the water pump is started to extract it for subsequent reuse, while the fine sand is located between the positioning plate and the second filter plate. The positioning plate and the second filter plate are lifted by using a lifting mechanism, and the fine sand on the positioning plate can be collected. After separation in this way, the surface solid matter is collected by the inclined setting of the filter plate itself. This method of collection is not thorough enough, and manual material discharge is required for collection, and the degree of automation is low. At the same time, there are gaps on the discharge port, and the waste slurry water is easy to flow out, which affects the equipment. For this reason, we propose a recycling device for waste slurry water from a concrete mixing station. Utility Model Content

The extrusion plate 2 19 is located on the moving track of the arc plate 15. When the arc plate 15 moves with the limiting plate 13, the extrusion plate 2 19 will extrude the arc surface of the arc plate 15, so that the arc plate 15 drives the limiting rod 14 to move, so that the limiting rod 14 is separated from the limiting groove 17. A connecting plate 20 is provided on one side of the extrusion plate 29. The connecting plate 20 is fixed on the outer wall of the recycling platform 1.
