Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of waste concrete recycled aggregate separation, specifically to a waste concrete recycled aggregate separation device. BACKGROUND

[0002] Recycled aggregate is a particle produced by crushing waste concrete in construction waste, and using recycled aggregate as aggregate in preparing ready-mixed mortar can effectively reduce the pollution caused by traditional construction waste landfill to the environment, but the existing waste concrete recycled aggregate separation device still has certain defects in use.

[0003] In the use process, because the composition of recycled aggregate is complex, screening is needed, but conventional small screening equipment cannot bear the screening of large weight and large volume of recycled aggregate mixture, and large screening devices have low screening efficiency, and it is difficult for workers to master the screening situation inside the screening bin, which is not convenient for repeated feeding and screening.

[0004] In order to overcome the above defects, the prior art 1 (Chinese patent with application number 202320151793.1 and application date 2023-02-08) is a building waste recycled aggregate separation device, which comprises a rack, a separation bin, a sliding seat, a sliding frame, an extension discharge cylinder, a material storage bin and a driving cylinder. By setting the sliding frame, the sliding seat and the separation bin set on the rack are guided to slide, so that the separation bin drives the inside to be screened aggregate to slide on the rack, and the driving cylinder can drive the separation bin to slide on the rack, so as to play a vibrating role on the aggregate to be screened. When the driving cylinder is not connected with the separation bin, the sliding seat is supported by the elastic element set on the sliding frame, and the extension and retraction of the elastic element can reflect the amount of aggregate inside the separation bin, so that the worker can know whether the small particle size renewable aggregate inside the separation bin has completely entered the material storage bin through the extension discharge cylinder. If the sliding seat stops sliding, no small particle size aggregate can be separated out, and the feeding can continue.

[0005] Although the prior art can master the screening situation inside the screening bin, in the working process, the separation bin drives the aggregate to be screened to shake and screen on the filter plate, the whole filtered material is not convenient to take out, and the sliding frame and the sliding seat need to be frequently slid, which may cause sliding to be not smooth after long time use, thereby affecting the normal operation of the equipment. The whole equipment structure is relatively complex, which increases the installation and maintenance cost, and the structure can only perform screening operation, so that the metal impurities contained in the waste concrete need to be treated twice, which reduces the overall operation efficiency.

[0006] In view of the above problems, it is urgent to make innovative design on the basis of the original waste concrete recycled aggregate separation device, therefore we put forward the waste concrete recycled aggregate separation device can well solve the above problems. Utility model content
