Abstract
Description
Technical Field
[0001] This utility model relates to the field of particulate material separation technology, and to a particulate material sorting device, particularly to a particulate material sorting device with good screening effect, high screening efficiency and no screen clogging problem. Background Technology
[0002] Lightweight aggregates refer to aggregates with a bulk density of no more than 1200 kg / m³, including lightweight coarse aggregates and lightweight fine aggregates. Lightweight coarse aggregates have a particle size of no less than 5 mm and a bulk density of no more than 1000 kg / m³; lightweight fine aggregates have a particle size of less than 5 mm and a bulk density of no more than 1200 kg / m³. These aggregates are often mixed with ordinary fine aggregates, cement, water, admixtures, and additives to produce lightweight aggregate concrete and other building materials, which play a role in reducing structural weight and improving thermal insulation performance in construction projects. However, in concrete applications, lightweight aggregates need to be finely graded to ensure their effectiveness and performance stability in concrete. Particle size classification is the most common type of grading for lightweight aggregates. Traditionally, vibrating screening is used for fine grading of lightweight aggregates, but this process suffers from problems such as easy screen clogging, incomplete screening, and low screening efficiency.
[0003] Therefore, it is of great practical significance to develop a particulate material sorting device that has good screening effect, high screening efficiency and does not cause screen clogging. Utility Model Content
[0004] Due to the aforementioned defects in the existing technology, this utility model provides a particulate material sorting device with good screening effect, high screening efficiency and no screen clogging problem.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A particulate material sorting device includes a material bin, a multi-stage cyclone separator kit, a bag filter, and a dust collection fan;
[0007] Each stage of the cyclone separator kit includes a fan and a cyclone separator. The gas inlet of the fan and the cyclone separator are connected through a feed pipe, and the gas outlet of the cyclone separator is connected to the inlet of the bag filter through a discharge pipe.
[0008] The multi-stage cyclone separator kits are arranged sequentially from low to high. The material outlet of the material silo is connected to the feed pipe of the first-stage cyclone separator kit, and the ash hopper outlet of the cyclone separator of the previous stage is connected to the feed pipe of the next stage cyclone separator kit.
[0009] The bag filter and the dust collector fan are connected by an exhaust pipe.
[0010] The material processing procedure in the particulate material sorting device is as follows:
[0011] Material flows from the material silo into the feed pipe of the primary cyclone separator kit. Under the action of the fan in the primary cyclone separator kit, the airflow transports the material to the primary cyclone separator. The primary cyclone separator separates the material. The lighter material 1 flows with the gas from the gas outlet through the primary discharge pipe into the bag filter dust collector, while the heavier material 2 is separated and flows out from the ash hopper outlet of the primary cyclone separator into the feed pipe of the secondary cyclone separator kit. Under the action of the fan in the secondary cyclone separator kit, the airflow transports the material to the secondary cyclone separator. The secondary cyclone separator separates the material. The lighter material 2 flows with the gas from the gas outlet through the secondary discharge pipe into the bag filter dust collector, while the heavier material 2 is separated and flows out from the ash hopper outlet of the secondary cyclone separator.
[0012] Assuming that the materials are divided into smallest, medium, and largest particles according to their particle size from smallest to largest, the heaviest material is medium plus the largest, the lightest material is smallest, the lightest material is medium, and the heaviest material is largest, this achieves fine sorting of particulate materials.
[0013] The above process does not cause material to clog the screen. The screening range of the material can be controlled by controlling the frequency of the blower. It has good adjustability and applicability, good screening effect and high screening efficiency, and good application prospects.
[0014] As a preferred technical solution:
[0015] As described above, the particulate material sorting device has a two-stage cyclone separation kit.
[0016] As described above, a particulate material sorting device includes a primary cyclone separator kit comprising a primary fan and a primary cyclone separator. The gas inlet of the primary fan and the primary cyclone separator are connected through a primary feed pipe, and the gas outlet of the primary cyclone separator is connected to the inlet of a bag filter through a primary discharge pipe.
[0017] The two-stage cyclone separator kit includes a two-stage fan and a two-stage cyclone separator. The gas inlet of the two-stage fan and the two-stage cyclone separator are connected through a two-stage feed pipe, and the gas outlet of the two-stage cyclone separator is connected to the inlet of the bag filter through a two-stage discharge pipe.
[0018] In the particulate material sorting device described above, the material outlet of the material bin is connected to the primary feed pipe, and the ash hopper outlet of the primary cyclone separator is connected to the secondary feed pipe.
[0019] The above technical solution is only one feasible technical solution of this utility model. The protection scope of this utility model is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.
[0020] Compared with the prior art, the above-mentioned utility model has the following advantages or beneficial effects:
