Description

A device for secondary crushing system

Technical Field

The utility model relates to the technical field of construction waste treatment, in particular to an equipment device of a secondary crushing system.

Background Art

The waste concrete in construction waste is used as recycled aggregate after crushing, screening, sorting, cleaning and other processes to replace part of natural sand and gravel aggregate to make recycled aggregate concrete. This recycled aggregate concrete is a green concrete with the advantages of saving resources, reducing costs and improving performance. Since construction waste is mixed with all kinds of waste, it needs to be sorted before crushing. There are coarse crushing, medium crushing and fine crushing processes. The output and finished product particle size are adjusted according to demand. The recycling of construction waste needs to be processed by a multi-stage crushing system.

The current secondary crushing system is to crush large volumes of waste materials with a jaw crusher and then use an impact crusher, sand making machine and other operations according to the characteristics of the material. Since there may be large differences in factors such as the particle size, hardness and impurity content of the material during the secondary crushing process, the size of the particles produced is uneven, which is not convenient for later use. Compared with primary crushing, secondary crushing requires more time and manpower for discharge and screening of materials, and the efficiency is lower.

Utility Model Content

In order to solve the above problems, the utility model provides an equipment device of a secondary crushing system, which screens the secondary crushed aggregates and improves the uniformity of the slag after the secondary crushing. The crushed slag is directly discharged through a conveying mechanism, which is easy to operate.

In order to solve the above technical problems, the technical solution provided by the utility model is: an equipment device of a secondary crushing system, comprising a base and a crushing box, support rods are provided at the four corners below the crushing box, a box cover is provided on the crushing box, and connecting plates are provided on the side edges opposite to the box cover and the crushing box, and the connecting plates are fixedly connected by bolts and nuts, a feed hopper is provided on the box cover, a crushing mechanism for crushing construction waste is provided in the crushing box, a discharge hopper is provided below the crushing box, and receiving plates are symmetrically provided on the base, and a conveying mechanism for conveniently conveying crushed materials is provided between the receiving plates.

As an improvement, a screen plate is obliquely provided in the discharge hopper, the screen plate is hinged to the crushing box and is rotatably connected to the discharge hopper, and the screen plate extends to the outside of the crushing box.

As an improvement, the crushing mechanism includes two rotating shafts rotatably connected to the crushing box, and a plurality of crushing teeth are staggered on the two rotating shafts. One end of the rotating shaft extends out of the crushing box and is provided with a gear, and the two gears are meshed with each other.

As an improvement, a motor is provided on the outside of the crushing box, and the motor is fixedly connected to the crushing box through an externally extending bracket. The motor output shaft is provided with a driving pulley, and one of the rotating shafts extends to the outside of the crushing box and is provided with a driven pulley, and a transmission belt is provided between the driving pulley and the driven pulley.

As an improvement, the support rod is located outside the material receiving plate, a damping shock absorber is provided between the support rod and the base, and the discharge hopper extends between the material receiving plates.

As an improvement, the conveying mechanism includes a conveyor belt, a plurality of rollers are rotatably provided between the receiving plates, the rollers are slidably connected to the conveyor belt, and a driving device is further provided in the receiving plate for driving one end to rotate, and one end of the conveyor belt extends to the outside of the base.

The advantages of the utility model are that after the construction waste is sorted and crushed by the crushing mechanism, it needs to be filtered through the screen, and the finely crushed materials fall into the conveying mechanism for discharge, while the residual materials falling from one side of the screen need to be crushed again, and the slag after screening falls on the transmission belt. At this time, the slag particles are relatively uniform, which improves the quality of secondary crushing. At the same time, the crushed slag is automatically discharged after falling directly, and the large-diameter setting of the discharge hopper can prevent blockage, which greatly improves the processing efficiency in the secondary crushing system process.
