Feeding structure of quartz sand sorting device

Technical Field

The utility model relates to a quartz sand processing technology field, concretely relates to quartz sand sorting unit's feed structure.

Background

At present, the domestic production process of the quartz sand mainly comprises the following steps: the method comprises the following steps of mining, crushing, cleaning, drying, sorting and the like, wherein the sorting is generally carried out by adopting a vibration screening machine, a plurality of layers of screening plates are arranged in the vibration screening machine, namely, each layer of screening plate is screened according to the set granularity to obtain quartz sand with different granularities (meshes), but the screening mode has many problems, namely, the granularity of the firstly sorted quartz sand is not uniform, and some fine particles are easy to mix in larger sand grains, so that the granularity distribution of finished sand products cannot reach the standard due to different meshes of the screened standard sand; secondly, during the working process of the vibrating screen machine, a large amount of dust is generated due to the impact between sand grains or between the sand grains and the screen plate, the main component silicon dioxide of the dust has great health threat to human bodies, if the vibrating screen is not tightly sealed, the dust can fly around in a production area, the separated sand grains need to be further cleaned, and finally, due to the fact that the sand grains continuously impact the screen plate of the vibrating screen during the separation process, the durability of the screen plate is reduced, and the screen plate needs to be replaced after being used for a period of time. Therefore, the method of adopting the vibration screening is only suitable for the production of small batches.

The conventional process flow of the quartz sand is long at present, and the conventional process flow is not suitable for enterprises with large quartz sand yield, and in the quartz sand sorting device, a feeding structure of the quartz sand sorting device is usually transmitted by a conveyor belt, and the conveyor belt can give horizontal component force to the quartz sand, so that the subsequent sorting is not facilitated.

Further, a rubber layer is bonded on the upper surface of the buffer plate.

Has the advantages that: protect the buffer board, prevent that the buffer board surface from damaging to reduce the time of shutting down and changing the buffer board, thereby reach the effect of practicing thrift the cost, raising the efficiency.

Further, the one end slope that the buffer board kept away from the feeding incasement wall sets up downwards.

Has the advantages that: the effect of leading is carried out quartz sand, also can avoid quartz sand to pile up on the buffer board simultaneously for ejection of compact transportation effect variation.

Furthermore, the overflow device is a rectangular box with an opening at the top, the sand discharge port is positioned on the rectangular box, and the height of the side wall of the rectangular box with the sand discharge port is lower than that of the side wall of the rectangular box without the sand discharge port.

Has the advantages that: the lateral wall through not being equipped with the sand discharge opening blocks the quartz sand in the overflow arrangement for quartz sand can only be followed sand discharge opening and discharged, compares in the unanimous condition of rectangle case lateral wall height, and this scheme has avoided quartz sand to rise and the unrestrained situation of quartz sand that leads to of water level liquid level to appear.

Further, the water inlet is communicated with a water spraying disc, and the water spraying disc is arranged in the overflow device.

Has the advantages that: the water inlet is prevented from being blocked by quartz sand settlement through the water spraying disc.

Furthermore, a support rod is arranged between the buffer plate and the side wall of the feeding box.
