[0002] With the development of science and technology, the demand for high-purity quartz sand is increasing, especially in the semiconductor, photovoltaic, optical fiber and high-precision glass industries. Traditional quartz sand processing methods can only remove large impurities and some fine particles, and cannot meet the requirements of high purity and low impurity content. Therefore, it is an urgent need for the industry to develop an efficient multi-stage processing device that can significantly improve the purity of quartz sand.

[0003] A Chinese patent with authorization announcement number CN213726760U discloses a multi-stage crushing device for quartz sand processing. The quartz stone entering through the feed port is initially crushed by the primary crushing component and then further crushed by the secondary crushing component, which can ensure the crushing particle size of the quartz stone and improve the processing efficiency of quartz sand; the filter net can filter and screen the crushed products to obtain qualified products, and the vacuum cleaner can absorb the dust generated during the crushing process to prevent the dust from entering the surroundings and affecting the working environment.

[0004] However, this technical solution still has at least the following defects: the device cannot screen the magnetic material contained in the quartz sand, and the crushing level is low. After secondary crushing, the unqualified quartz sand may remain on the filter screen and cause blockage, which is not conducive to subsequent screening.

[0066] Embodiment 3:

[0067] like Figures 7 to 14 As shown, a multi-stage quartz sand processing device includes a processor, and the processor is configured with a control system for the multi-stage quartz sand processing device, and the control system includes an input module, a weighing module, a crushing module and a screening module;

[0068] The input module is used to input crushing instructions and feeding instructions. The crushing instructions are used for the initial crushing operation, and the feeding instructions are used for the initial feeding operation of the robot arm 403.

[0069] The weighing module is used to obtain the mass of each part of the quartz sand before and after processing;

[0070] The crushing module is used to crush quartz sand. The crushing module is equipped with a crushing program, which includes controlling the power device 106 to work and perform the crushing operation after receiving the crushing instruction;

[0071] The screening module is used to screen the crushed quartz sand. The screening module is configured with a rotation program for controlling the rotation of the electromagnet 204 and a magnetic control program for switching the electromagnet 204 .

[0072] The weighing module includes a discrimination strategy, which includes obtaining the mass M1 of quartz sand on the discharge box 402 before each processing, the mass ΔM increased in the finished material collection box 401 after each processing, and the mass M2 of impurities adsorbed on the electromagnet 204 after each processing. When M1=ΔM+M2, all the quartz sand in the discharge box 402 falls into the finished material collection box 401 and is adsorbed on the electromagnet 204, which indicates that the crushing module is completed and a temporary adjustment instruction is generated. When M1>ΔM+M2, not all the quartz sand in the discharge box 402 falls into the finished material collection box 401 and is adsorbed on the electromagnet 204, which indicates that the crushing module is not completed and a work instruction is generated.

[0073] The crushing module includes a power control strategy, which includes obtaining instructions generated by the discrimination strategy. When a temporary adjustment instruction is obtained, the power control strategy controls the power device 106 to suspend operation through the crushing program. When a working instruction is obtained, the power control strategy controls the power device 106 to continue to work through the crushing program.

[0074] The crushing module is provided with a feeding program, which is used for the robot arm to execute the operation of placing the quartz sand in the discharge box 402 into the discharge barrel 100 and the reset operation. The crushing module also includes a feeding control strategy, which includes that when receiving a temporary adjustment instruction or a loading instruction, the robot arm 403 executes the feeding program to allow the quartz sand to enter the discharge barrel 100, and when M1=0, the quartz sand in the discharge box 402 is dumped, and the robot arm 403 executes the feeding program to reset;

[0075] The crushing module includes a fineness adjustment program, which is used to control the lifting of the oil cylinder when receiving a temporary adjustment instruction, and adjust the distance between the crushing base 101 and the crushing piece 104 to represent the adjustment of the crushing fineness;

[0076] The crushing module also includes a gradient crushing strategy, which includes dividing the crushing fineness into five levels: I. II. III. IV. V. When receiving a temporary adjustment instruction, the crushing module increases the crushing fineness by one level through a fineness adjustment program, and when receiving a work instruction, the crushing module maintains the crushing fineness at the current level through a fineness adjustment program;

[0077] The pulverizing module also includes a feedback stop strategy, which includes obtaining the pulverizing fineness level being executed by the pulverizing module. When the executed pulverizing fineness level is V, the module stops working after receiving a temporary adjustment instruction, otherwise it continues working.

[0078] The screening module is configured with an initial angle α and a determination angle γ. The screening module also includes a magnetic control strategy, which includes obtaining a real-time monitoring angle β of the angle sensor 206. When β=α, the electromagnet 204 is in an inclined state to indicate that the end of the electromagnet 204 is located at the top of the finished material collection box 401, and a power-on instruction is generated at the same time. When β-α<γ, the electromagnet 204 is in a rotating state to indicate that the electromagnet 204 is in a moving process, and a power-on instruction is generated at the same time. When β-α=γ, the electromagnet 204 is in a vertical state to indicate that the end of the electromagnet 204 is located at the top of the waste material collection box 400, and a power-off instruction is generated at the same time.

[0079] The electromagnet 204 executes the magneto control program to keep the working state when receiving the power-on instruction to maintain the magnetic force, and executes the magneto control program to disconnect the power supply when receiving the power-off instruction to make the magnetic force disappear;

[0080] The screening module also includes a rotation control strategy. The rotation control strategy includes that when M1=ΔM+M2, the crushing module completes the crushing, and the rotation control strategy controls the contraction of the hydraulic rod 205 through a rotation program to represent the rotation of the electromagnet 204.

The rotation control strategy also includes that when β-α=γ, the rotation control strategy controls the extension of the hydraulic rod 205 through a rotation program to represent the resetting of the electromagnet 204.

[0081] The implementation principle of a multi-stage quartz sand processing device of this embodiment is as follows: when working, the quartz sand to be processed is placed in the discharge box 402, and the mechanical arm 403 is started. The mechanical arm 403 pours the quartz sand in the discharge box 402 into the discharge barrel 100, and the discharge box 402 is moved to the bottom of the discharge port 202 by the mechanical arm 403. At this time, the power device 106 drives the crushing member 103 and the pulverizing member 104 to rotate through the rotating column 105, and the crushing member 103 performs preliminary crushing on the quartz sand in the discharge barrel 100. The crushed quartz sand enters the pulverizing base 101 downward under the action of the external thread of the crushing member 103. Under the action of the pulverizing base 101 and the pulverizing member 104, the quartz sand is preliminarily crushed, and the crushed quartz sand falls;

[0082] The fan 201 is started, and the fan 201 blows out wind, so that the fine quartz sand and impurities can move to one side under the action of the wind when the quartz sand falls, and at the same time, the magnetic impurities contained in the quartz sand are blown toward the electromagnet 204 under the action of the wind, and the electromagnet 204 keeps the magnetic attraction state, while the fine quartz sand is not affected by the magnetic force, and slides along the surface of the electromagnet 204 to the finished material collection box 401;

[0083] Unqualified quartz sand falls on the baffle 203. When the rotating column 105 rotates, the guide rod 308 is driven to move up and down through the guide groove 309. The guide rod 308 moves up and down while driving the connecting plate 304 to move up and down, so that the rack 303 moves up and down. The rack 303 drives the gear 302 to rotate through meshing, so that the transmission shaft 300 and the cam 301 rotate, and the cam 301 drives the baffle 203 to vibrate up and down, so that the unqualified quartz sand can fall into the discharge box 402.

[0084] After completing the crushing of the quartz sand, the electromagnet 204 rotates to a vertical state as a whole, and the power is turned off to eliminate the magnetic force, and the magnetic impurities fall into the waste collection box 400, and then the electromagnet 204 rotates to reset and is powered on again. During this process, the robotic arm 403 pours the unqualified quartz sand in the discharge box 402 into the discharge barrel 100 for further processing. At the same time, the cylinder 102 contracts to reduce the distance between the crushing base 101 and the crushing element 104, so that the crushing degree is finer. This cycle is repeated to realize the cyclic multi-stage processing of the quartz sand.

[0085] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
