1、 Product Introduction:

HDVX-The series mechanism sand powder remover isWuxi Hushan Energy saving Technology Co., Ltd. is in a static stateVAn upgraded product developed by introducing dynamic powder selection technology on the basis of the shape selection machine, using a dynamic classifier and a static classifierVThe combination of a shape selection machine and a fine powder collector is characterized by being composed of a fan, a coarse, medium, and fine sand dynamic and static sorting device, and a fine powder collector; The sorting principle of this product is advanced and breaks through the traditional process principle of washing sand and gravel sorting. Multiple grading systems are used, and the air fluid dynamics analysis method is adopted to optimize the material flow field according to the characteristics of the sand and gravel industry. This significantly reduces the operating resistance of the equipment, improves sorting efficiency, is easy to operate, has a sturdy design, low maintenance and usage costs, and is very energy-saving and cost-effective. It is a new method and new way for mechanism sand enterprises to improve product quality in the new situation. After being introduced to the market, this powder sorting machine has received unanimous praise from many enterprises.

2、 Working principle:

The cyclone separator is located around the dynamic rotor sorting chamber, and its inlet is connected to the outlet shell of the dynamic sorting chamber through a pipeline. The outlet of the cyclone separator is connected to the inlet of the fan through a pipeline, and the outlet for collecting fine powder is located at its lower end; staticVThe shape selection machine consists of a feeding deviceVThe device consists of a dispersing and separating device, a medium fine sand discharge port, and a coarse sand discharge port,VThe upper part of the shape selection machine is equipped with a feed inlet and a uniform fabric sealing device, with one end as the air inlet and the other end as the air outlet. The dispersing device is set from top to bottom in sequenceVInside the shaped tube and located on one side of the air inlet, the grading device is sequentially arranged from top to bottom inside the loose packing tube and located on one side of the air outlet. A feeding channel is formed between the dispersing device and the grading device,VAt the bottom of the channel of the shaped tube, there is a coarse sand discharge portVThe lower separation device of the shaped tube is equipped with a medium fine sand discharge port on one side to collect and grade the medium fine sand (this port can be omitted according to user needs);VThe inlet of the shaped tube is connected to the outlet of the circulating fan through a connecting tube,VThe outlet of the shaped tube is connected to the inlet duct of the dynamic classifier through a transition pipe. The dynamic classifier consists of an inlet duct with a guiding inner cone, a classification chamber with a cage shaped rotor, and an outlet housing.

Material passes through static stateVThe upper feeding port of the shape classifier is fed in, and the mixture is evenly dispersed and dropped through the buffering of the material blocking and uniform distribution device. It enters the middle and disperses the classification shellVThe material particles in the classification area of the shape classifier are subjected to secondary classification under the dual action of wind force and gravity of the material particles. After being dispersed by the dispersing grid inside the intermediate dispersing and grading shell and graded by the grading device, the sorted coarse sand isVThe coarse sand discharge port at the bottom of the channel of the shaped tube is discharged. By dispersing the coarse and fine sand and powder into the dynamic rotor classification chamber and sorting the airflow, the dust particles will undergo secondary classification of coarse and fine powder under the action of gravity, wind force, and rotational centrifugal force as the rotor cage rotates and cuts the particle size,Fine powder, due to its low centrifugal force, cannot overcome the resistance of gas and is carried by the airflow through the grading surface before being discharged,Carried by the airflow, it enters the cyclone through the grading ring and the outlet shell, and completes gas-solid separation in the low resistance cyclone. The fine powder is discharged from the lower outlet of the cyclone. Under the action of centrifugal force, the coarse particles (medium fine sand) after secondary classification adhere to the wall and settle in the powder selection chamber, falling intoVThe medium fine sand discharge outlet at the lower part of the tube separation device is discharged.
