Description
Technical Field
[0001] The utility model relates to the technical field of building material recycling, in particular to a device for recycling waste from concrete production. Background Art
[0002] With the growing demand for commercial concrete in the construction market, commercial concrete production has become the main building materials industry in cities. Generally, there will be concrete waste at construction sites. In order to improve resource utilization, concrete waste will be collected and recycled through a process to be turned into recycled concrete and then put into use.
[0003] Prior art publication number CN220634521U discloses a concrete waste recycling device comprising a collection chamber and a crushing chamber, wherein the crushing chamber is mounted on the top of the collection chamber. The concrete waste recycling device utilizes a screening plate, a vibration motor, an electric push rod, and a push plate in conjunction with each other, so that waste crushed by a crushing roller in the concrete waste recycling device falls onto the screening plate. The vibration motor at the bottom of the screening plate operates and drives the screening plate to vibrate, thereby screening the crushed waste. Waste that meets recycling requirements falls into the inner side of the collection chamber, while larger waste that cannot be screened is discharged through the end of the screening plate. The screened waste accumulates in the collection chamber. After the waste is completely recovered, the electric push rod operates and pushes the push plate to slide in the collection chamber, discharging the accumulated waste through a second output port. This allows the concrete waste recycling device to distinguish the crushed waste and ensure the quality of waste recovery.
[0004] However, during actual use, some debris may get stuck on the surface of the screen plate, causing the screen holes to be blocked, affecting the screening effect of the screen plate. The above-mentioned concrete waste recovery device does not have the function of cleaning the screen plate during use, which is inconvenient to use and reduces the screening efficiency. Therefore, a concrete production waste recycling and utilization device is proposed to solve the above-mentioned problems. Utility Model Content
