Problems solved by technology

Due to different usage methods and uses, sand and gravel still need to be further sorted after being crushed. At present, the methods commonly used in the industry, such as gravity sedimentation classification, overflow classification, and centrifugal classification, all have low classification efficiency and wide product particle size distribution. problems, can no longer meet the needs of the market

Embodiment 1

[0029] A kind of sand making and sorting equipment, such as figure 1 As shown, the sorting equipment includes: feed port 1, feed pipe 2, piston rod 3, parallel excitation table 4, grading suction cup 5, solenoid valve 6, air pump 7, gas pipeline 8, collection chamber 9 , Discharge pipe 10, recovery chamber 11, PLC13, position sensor 12. The feed inlet is connected to the feed pipe, located in the middle of the feed pipe, and is used for feeding sand and gravel raw materials; the tail end of the feed pipe is provided with a piston rod, and the piston rod is used to pass the sand and gravel raw materials through the feeding pipe. The feed pipe is pushed onto the parallel vibration table, and the front end of the feed pipe is flexibly connected to the parallel vibration table; a graded suction cup is arranged above the parallel vibration table, and the graded suction cup completely covers the parallel vibration table, but There is no direct contact between the two, and there is ...

Embodiment 2

[0033] A kind of sand making and sorting equipment, its overall structure is as follows Figure 4 As shown, the PLC is electrically connected to the upper computer, the piston rod, the solenoid valve, the air pump, the position sensor, the driver 1, the driver 2 and the driver 3 respectively. The PLC is connected to the upper computer to set the feeding times of the piston rod, the type of sand and gravel particles, the particle size range to be sorted, the suction time and other parameters; the PLC is connected to the piston rod to control the movement of the piston rod. switch, thereby controlling the feeding times of the piston rod; the PLC is connected with the solenoid valve, and the solenoid valve is connected with the air pump, and is used to control the switch of the air circuit, and set the pumping rate of the air pump, thereby controlling the opening time of the air circuit; Said PLC is connected with driver 1, driver 2, and driver 3, and said driver 1, driver 2, and...

Embodiment 3

[0035]A kind of sand making and sorting equipment, adopting PC+PLC servo control system, its overall structure is as follows Figure 4 As shown, the piston rod, the three driving motors of the parallel excitation table, the solenoid valve, the air pump, and the position sensor are all controlled by the PLC controller, and the PLC communicates with the PC host computer through the R232 serial port. The workflow of the device is as follows Figure 5 Shown:

[0036] 1) After the equipment is powered on, the control system is initialized, and the position sensor and solenoid valve are set;

[0037] 2) Add sand and gravel raw materials through the feed port, then enter the feed pipe, start the piston rod, push the sand and gravel raw materials into the parallel excitation table, and check whether the feeding is completed, if not, the piston rod continues to work until Push all gravel materials into the parallel excitation table;

[0038] 3) On the PC host computer, select the t...

Abstract

The invention provides a kind of sand making and sorting equipment, which adopts the dynamic analysis method to separate the sand grains, breaking through the sand and gravel sorting theory of conventional open-air washing. Grade, its internal structure is reasonable, the sorting effect is good, the energy saving effect is remarkable, the dust emission is reduced, and the environmental protection meets the standard; it can form a closed-circuit or open-circuit system with various grinding equipment such as ball mills, Raymond mills, impact mills, and jet mills.

Description

technical field [0001] The invention relates to the field of sand and gravel separation, in particular to sand making and separation equipment. Background technique [0002] At present, the demand for all kinds of fine powder materials in food, building materials, chemical industry, metallurgy, refractory and other industries is increasing day by day, and there are many types of equipment for processing fine powder materials, such as ball mill, jet mill, Raymond mill, super Crusher, roller mill, claw mill and various hammer mills, etc. The particle size distribution of the pulverized sand and gravel is wide, and the large and small particles stick together to form hard agglomerates, and the shape of the particles is semi-self-determined and amorphous. Due to different usage methods and uses, sand and gravel still need to be further sorted after being crushed. At present, the methods commonly used in the industry such as gravity sedimentation classification, overflow classif...
