Description

Technical Field

[0001] The utility model relates to the technical field of sand and gravel aggregate production, in particular to a sand and gravel aggregate vibration air separation device. Background Art

[0002] Recycled sand and gravel aggregates for construction are sand and gravel aggregates that are crushed and processed from discarded concrete blocks generated during building demolition, road renovation, concrete production, engineering construction and other situations. These sand and gravel aggregates can be recycled after being vibrated and screened and then separated by wind separation.

[0003] A vibration air separation device for recycled aggregate of construction waste with publication number CN 106717205 A. The main housing is mounted on the supporting device through a vibration reduction device, and the vibration device is mounted on the main housing. The lower part of the main housing is a bellows, and the upper part of the bellows is in the shape of a step from the feeding end to the discharging end of the main housing, and the inclination angle α of the bellows step surface is 3° to 7°. A wear-resistant plate is installed on the step above the bellows, and an adjustment plate is connected to the edge of the wear-resistant plate, and the width of the adjustment plate exceeds the edge of the step. A row of air outlets is installed on the bellows wall below the adjustment plate; the air outlet on the last step is a separation air outlet. A separation material collection device consisting of a heavy material collection bin, a sorting roller and a light material collection bin is arranged at the discharging end of the main housing. It has the characteristics of reasonable structure, superior performance, fine classification and high operating efficiency, and is particularly suitable for the sorting and resource utilization of construction waste.

[0004] However, when the above device is used, it can realize the sorting of recycled sand and gravel aggregates in construction waste. However, after the recycling sand and gravel aggregates are sorted by the above device, there will be a phenomenon that the larger volume of lightweight aggregates are mixed in the heavy collection bin, and the smaller volume of recycled sand and gravel aggregates in the heavy aggregates are mixed in the light collection bin, resulting in low accuracy of recovery and air separation. In addition, when the construction waste of the above device is poured into the raw material placement mechanism, a certain amount of dust will be generated, which will affect the workshop environment and cause a certain waste of resources for the construction waste raw materials. The processed recycled sand and gravel aggregates will fall directly to the ground, affecting the quality of the sand and gravel aggregates in the later use, and the storage is inconvenient, which brings certain adverse effects to people's use process. Therefore, we propose a new vibration air separation equipment for sand and gravel aggregates. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting springs, screen plates, vibration components, air separation components, etc., when the sand and gravel aggregates are started to be air-separated, the sand and gravel aggregates are first put into the air separation box through the feed trough, and the sand and gravel aggregates fall onto the first screen plate. At this time, the motor is started, and the motor drives the half gear to rotate, thereby driving the meshing gear to rotate, and at the same time, the connecting rod on the gear rotates accordingly. At this time, the rotating arm is driven to rotate by the connecting rod, so that the hammer block is lifted and hits the screen plate. At this time, the screen plate moves upward with the hitting, driving the connecting plate to move upward, stretching the spring. When the gear rotates to the half that is not meshed with the half gear, the hammer block drives the rotating arm to fall freely, and the spring can rebound, thereby causing the screen plate to vibrate, so that the sand and gravel aggregates on the screen plate are screened layer by layer through vibration, and the larger sand and gravel aggregates remain on the first screen plate, the smaller sand and gravel aggregates remain on the second screen plate, the smallest sand and gravel aggregates remain on the last screen plate, and the smaller sand and gravel aggregates fall into the aggregate drawer one.

Since the sand and gravel aggregates are screened by volume before air separation, the weight of the sand and gravel aggregates on the same layer is only affected by the density of each piece of sand and gravel aggregate itself. Therefore, the heavy aggregate and light aggregate on each layer can be separated by air separation, avoiding the problem of mixing of light aggregate and heavy aggregate in the sand and gravel aggregate after vibration screening. The control is convenient and the air separation efficiency is high.

No dust is raised during the whole process, avoiding the dust generated during the air selection process to pollute the environment and harm human health, and the equipment is more environmentally friendly. When the vibration screening and air selection are completed, open the sealed door, collect the aggregate on the screen plate, and pull out the aggregate drawer 1 and the aggregate drawer 2.
