[0032] The present invention also provides: a method for a grinding device for machining tantalum carbide, comprising the following steps:

[0033] Step 1: Tantalum carbide transfer and loading, horizontal and vertical cutting;

[0034] Tantalum carbide is discharged into the feed box through the upper hopper and falls onto several conveyor belts;

[0035] After starting the servo motor 1, the servo motor 1 drives the single transmission roller to rotate, so that the single transmission roller drives a plurality of conveyor belts to move, so that the conveyor belts move along the two transmission rollers, and the tantalum carbide can be quantitatively conveyed and moved through the distance between the plurality of limiting rods;

[0036] When the tantalum carbide moved by the conveyor belt passes through several cutting wheels, the tantalum carbide applied by the limiting rod is cut by the cutting wheel, and the tantalum carbide can be cut horizontally into several strips of tantalum carbide;

[0037] The cutting wheel needs to start the cutting motor, and after the cutting motor starts, it drives the transmission rod to rotate, and the transmission rod can drive several cutting wheels to rotate;

[0038] After being horizontally cut by the tantalum carbide feeding structure 1, the tantalum carbide falls into the inner side of the tantalum carbide feeding structure 2 through the lower hopper, and is vertically cut by the tantalum carbide feeding structure 2 to cut the tantalum carbide into several small pieces, which are then transported into the tantalum carbide washing structure for subsequent processing;

[0039] Step 2: Washing and processing of tantalum carbide;

[0040] The tantalum carbide falling into the water washing cylinder needs to be started by the servo motor 2, which starts to drive the active rod to rotate, and the transmission auger 1 on the active rod slowly rotates inside the water washing cylinder, and the tantalum carbide inside the water washing cylinder is gradually moved to the unloading frame through the transmission auger 1;

[0041] When the servo motor 2 is started, a high-pressure water source is provided to the water supply pipe, and the high-pressure water source is sprayed into the water washing cylinder through the high-pressure atomizing spray plate through the water supply pipe, so as to flush the tantalum carbide moving slowly inside the water washing cylinder. The flushing water source is collected in the water receiving bucket through the filter water net 1, so that the water source inside the water receiving bucket is discharged into the drainage main pipe through the drainage branch pipe, and the drainage main pipe discharges the waste water into the external waste water tank for collection;

[0042] The washed tantalum carbide falls into the drying drum through the unloading frame, and the continuously transmitted active rod drives the pulley 1, so that the connecting belt of the pulley 1 moves, and the moving connecting belt drives the pulley 2, which drives the single driven rod through the rotating pulley 2, so that the single spur gear meshes with another spur gear, so that the two driven rods rotate at the same time, and the tantalum carbide inside the drying drum gradually moves to the tantalum carbide grinding structure through the transmission auger 2;

[0043] The dryer starts while the tantalum carbide moves inside the drying cylinder, compressing and heating the outside air and blowing it into the drying cylinder along the top air duct to dry the tantalum carbide inside the drying cylinder.

[0044] The excess water stains of the tantalum carbide during drying fall into the drainage bucket along the second filter screen, and the waste water can be discharged into the waste water tank through the drainage pipe, completing the washing and drying of the tantalum carbide.

[0045] Step 3: crushing and grinding of tantalum carbide;

[0046] The tantalum carbide discharged into the grinding cylinder through the drying cylinder will fall directly into the grinding cone cylinder due to gravity;

[0047] The stamping and crushing process requires the start of the stamping cylinder. When the stamping cylinder starts to rise, the grinding cone block rises away from the grinding cone tube, and after the stamping cylinder starts to descend, the grinding cone block is directly pressed down to quickly approach the tantalum carbide inside the grinding cone tube, and the tantalum carbide is stamped and crushed through the grinding cone block;

[0048] After a single punching operation, the punching cylinder is in a state of slowly applying force downwards to crush the tantalum carbide, so that the tantalum carbide deposited inside the grinding cone is continuously pressurized.

[0049] The grinding time for tantalum carbide after a single punching is 10 min;

[0050] The grinding process requires starting the servo motor 4. After the servo motor 4 is started, it drives the worm to rotate. The rotation of the worm engages with the worm wheel. The rotating worm wheel can drive the grinding cone block at the bottom of the inner shaft to rotate. The grinding cone block is continuously pressed down by the punching cylinder and directly approaches the grinding cone cylinder. The tantalum carbide inside is continuously ground by a single punching. The cycle working time is 2 hours for tantalum carbide crushing and grinding.

[0051] Step 4: Screening and cutting of tantalum carbide;

[0052] After the tantalum carbide is cyclically crushed and ground, the blower is started to compress the air outside the grinding cylinder and blow it into the grinding cylinder, so that the crushed and ground tantalum carbide inside the grinding cone is blown up, and some powdered tantalum carbide can float directly inside the grinding cylinder;

[0053] Start the exhaust fan, and after the exhaust fan is started, the tantalum carbide floating inside the grinding cylinder is sucked into the suction channel, so that the tantalum carbide passes through the obstruction of the inner filter and falls into the screening box from the suction channel;

[0054] The tantalum carbide inside the screening box is separated by the screening net. The tantalum carbide that passes through the screening net meets the use standards and is discharged and collected through the discharge hopper;

[0055] The tantalum carbide that has not passed through the screening net falls into the circulation bucket, and then falls to the bottom of the circulation cylinder through the circulation bucket. The servo motor three is started, and the servo motor three drives the circulation auger to rotate, so that the tantalum carbide can be directly circulated through the circulation cylinder and transferred to the grinding cylinder for circulation crushing and grinding of the tantalum carbide.

[0056] Technical effects and advantages of the present invention:

[0057] The present invention realizes efficient and stable material transmission by arranging tantalum carbide into a feed box and using a conveyor belt and a servo motor for quantitative transportation, starts a cutting motor and a transmission rod to drive a cutting wheel to cut the tantalum carbide horizontally, realizes precise cutting of the tantalum carbide, and improves the dimensional accuracy of the product. The tantalum carbide is cut horizontally and vertically by a tantalum carbide feeding structure 1 and a tantalum carbide feeding structure 2, and the processing flexibility of the product is further improved.

[0058] The present invention starts servo motor two and a water supply pipe, uses a transmission auger one and a high-pressure atomizing spray plate to wash tantalum carbide with water, effectively removes impurities on the surface of tantalum carbide, and uses a dryer to wind dry the tantalum carbide inside a drying cylinder to ensure the dryness of the product, and uses a stamping cylinder and a grinding cone block to stamp, crush and grind the tantalum carbide, thereby realizing fine processing of the tantalum carbide.

[0059] The present invention uses a blower and an exhaust fan to screen the ground tantalum carbide, and the tantalum carbide that meets the standards is separated and collected through a screening net, and the tantalum carbide that has not been screened enters a circulation system for re-crushing and grinding. The circulation bucket and the circulation cylinder realize the recycling of the unscreened tantalum carbide, thereby improving the utilization efficiency of the material, the degree of automation of tantalum carbide processing, the production efficiency and the product quality, and reducing the production cost and environmental impact.

[0119] Embodiment 5: According to the above embodiment, a method for a grinding device for machining tantalum carbide is provided in this embodiment, comprising the following steps:

[0120] Step 1: Tantalum carbide transfer and loading, horizontal and vertical cutting;

[0121] Tantalum carbide is discharged into the feed box 201 through the upper hopper 7 and falls onto a plurality of conveyor belts 204;

[0122] After starting the servo motor 206, the servo motor 206 drives the single transmission roller 203 to rotate, so that the single transmission roller 203 drives a plurality of conveyor belts 204 to move, so that the conveyor belts 204 move along the two transmission rollers 203, and the tantalum carbide can be quantitatively conveyed and moved through the distance between the plurality of limiting rods 205;

[0123] When the tantalum carbide moved by the conveyor belt 204 passes through a plurality of cutting wheels 207, the tantalum carbide applied by the limiting rod 205 is cut by the cutting wheel 207, and the tantalum carbide can be cut horizontally into a plurality of strips of tantalum carbide;

[0124] The cutting wheel 207 needs to start the cutting motor 209. After the cutting motor 209 is started, it drives the transmission rod 208 to rotate, and the transmission rod 208 can drive the plurality of cutting wheels 207 to rotate;

[0125] After being horizontally cut by the tantalum carbide feeding structure 1 2, the tantalum carbide falls into the inner side of the tantalum carbide feeding structure 2 5 through the lower hopper 202, and is vertically cut by the tantalum carbide feeding structure 2 5 to cut the tantalum carbide into several small pieces, which are then transported into the tantalum carbide washing structure 3 for subsequent processing;

[0126] Step 2: Washing and processing of tantalum carbide;

[0127] The tantalum carbide falling into the water washing cylinder 301 needs to be started by the servo motor 2 313, which drives the active rod 310 to rotate, and the transmission auger 1 311 on the active rod 310 rotates slowly inside the water washing cylinder 301, and the tantalum carbide inside the water washing cylinder 301 is gradually moved to the unloading frame 305 through the transmission auger 1 311;

[0128] When the servo motor 2 313 is started, a high-pressure water source is provided to the water supply pipe 304, and the high-pressure water source is sprayed into the washing cylinder 301 through the high-pressure atomizing spray plate 303 through the water supply pipe 304, and the tantalum carbide moving slowly inside the washing cylinder 301 is washed with water source, and the washing water source is collected in the water receiving bucket 308 through the filtering water net 1 307, so that the water source inside the water receiving bucket 308 is discharged into the drainage main pipe 323 through the drainage branch pipe 309, and the drainage main pipe 323 discharges the waste water into the external waste water tank for collection;

[0129] The washed tantalum carbide passes through the unloading frame 305 and falls into the drying cylinder 306. The continuously transmitting active rod 310 drives the pulley 1 312, so that the pulley 1 312 moves the connecting belt 314. The moving connecting belt 314 drives the pulley 2 317. The rotating pulley 2 317 drives the single driven rod 318, so that the single spur gear 319 meshes with another spur gear 319, so that the two driven rods 318 rotate at the same time, and the tantalum carbide inside the drying cylinder 306 is gradually moved to the tantalum carbide grinding structure 4 through the transmission auger 2 320.

[0130] While the tantalum carbide is moving inside the drying cylinder 306, the dryer 316 is started, and the outside air is compressed and heated and blown into the drying cylinder 306 along the top air duct 315, so as to dry the tantalum carbide inside the drying cylinder 306 by wind.

[0131] The excess water stains of the tantalum carbide during drying fall into the drainage bucket 322 along the water filter 321, and the waste water can be discharged into the waste water tank through the drainage pipe 323, thus completing the washing and drying of the tantalum carbide.

[0132] Step 3: crushing and grinding of tantalum carbide;

[0133] The tantalum carbide discharged into the grinding cylinder 401 through the drying cylinder 306 will fall directly into the grinding cone cylinder 402 due to gravity;

[0134] The stamping and crushing process requires starting the stamping cylinder 403. When the stamping cylinder 403 starts to rise, the grinding cone block 405 rises away from the grinding cone cylinder 402. After the stamping cylinder 403 starts to descend, the grinding cone block 405 is directly pressed down to quickly approach the tantalum carbide inside the grinding cone cylinder 402, and the tantalum carbide is stamped and crushed through the grinding cone block 405.

[0135] After a single punching operation, the punching cylinder 403 is in a state of slowly applying force downward, so that the tantalum carbide deposited inside the grinding cone 402 is continuously pressed;

[0136] The grinding time for tantalum carbide after a single punching is 10 min;

[0137] The grinding process requires starting the servo motor 421. After the servo motor 421 is started, it drives the worm 420 to rotate. The worm 420 rotates and engages with the worm wheel 419. The rotating worm wheel 419 can drive the grinding cone block 405 at the bottom of the inner shaft 418 to rotate. The grinding cone block 405, which is continuously pressed down by the punching cylinder 403, directly approaches the grinding cone cylinder 402, and performs a single punching and continuous grinding on the internal tantalum carbide. The cycle working time is 2 hours for tantalum carbide crushing and grinding.

[0138] Step 4: Screening and cutting of tantalum carbide;

[0139] After the tantalum carbide is cyclically crushed and ground, the blower 406 is started to compress the air outside the grinding cylinder 401 and blow it into the grinding cylinder 401, so that the crushed and ground tantalum carbide inside the grinding cone 402 is blown up, and some powdered tantalum carbide can float directly inside the grinding cylinder 401;

[0140] The exhaust fan 408 is started. After the exhaust fan 408 is started, the tantalum carbide floating in the grinding cylinder 401 is sucked into the suction channel 407, so that the tantalum carbide passes through the obstruction of the inner filter 409 and falls into the screening box 410 from the suction channel 407;

[0141] The tantalum carbide inside the screening box 410 is separated by the screening net 411. The tantalum carbide passing through the screening net 411 meets the use standard and is discharged and collected through the discharge hopper 414.

[0142] The tantalum carbide that has not passed through the screening net 411 falls into the circulation bucket 413, and then falls to the bottom of the circulation cylinder 415 through the circulation bucket 413. The servo motor 417 is started, and the servo motor 417 drives the circulation auger 416 to rotate, so that the tantalum carbide can be directly circulated through the circulation cylinder 415 and transferred to the grinding cylinder 401, so as to perform cyclic crushing and grinding processing on the tantalum carbide.

[0143] According to the above embodiments, the working principle of the present invention is:

[0144] Tantalum carbide enters the feed box 201 through the upper hopper 7 and is deposited on several conveyor belts 204; after the servo motor 1 206 is started, the motor drives the single transmission roller 203 to rotate, thereby driving the multiple transmission belts 204 to move, so that the tantalum carbide is quantitatively transported along the path of the transmission roller 203; when the tantalum carbide moves on the transmission belt 204, it passes through the cutting wheel 207 and is cut into several strips by the pressure applied by the limiting rod 205; the rotation of the cutting wheel 207 is driven by the cutting motor 209, and after the motor is started, the transmission rod 208 rotates accordingly, driving the cutting wheel 207 to rotate; the tantalum carbide that has been cut horizontally falls into the inner side of the tantalum carbide feeding structure 2 5 through the lower hopper 202, and then is cut longitudinally to cut the tantalum carbide into multiple small pieces, which are then transported to the tantalum carbide washing structure 3 for subsequent processing;

[0145] After the tantalum carbide falls into the water washing cylinder 301, the servo motor 2 313 is started, and the motor drives the active rod 310 to rotate, thereby causing the transmission auger 1 311 to slowly rotate in the water washing cylinder 301, and gradually moving the tantalum carbide to the unloading frame 305; at the same time, when the servo motor 2 313 is started, the water supply pipe 304 provides a high-pressure water source, and the water is atomized by the high-pressure atomizing spray plate 303 and sprayed into the water washing cylinder 301 to wash the slowly moving tantalum carbide. The washed water is collected in the water receiving bucket 308 through the water filter net 1 307. Then the wastewater is discharged into the main drainage pipe 323 through the drainage branch pipe 309, and finally the wastewater is discharged into the external wastewater tank; the washed tantalum carbide falls into the drying cylinder 306, and the continuous transmission of the active rod 310 drives the pulley 1 312, and then drives the connecting belt 314 and the pulley 2 317, so that the two driven rods 318 rotate at the same time, and the tantalum carbide is gradually moved to the tantalum carbide grinding structure 4 through the transmission auger 2 320; inside the drying cylinder 306, the dryer 316 is started, and the heated air is blown into the cylinder to dry the tantalum carbide by wind;

[0146] During the drying process, excess water flows into the drainage bucket 322 through the water filter 321, and the waste water is discharged into the waste water tank through the drainage pipe 323, completing the washing and drying of tantalum carbide; the tantalum carbide in the drying cylinder 306 falls into the grinding cylinder 401, and directly falls into the grinding cone cylinder 402 under the action of gravity; during the stamping and crushing process, the stamping cylinder 403 is started, the cylinder rises to make the grinding cone block 405 away from the grinding cone cylinder 402, and the cylinder descends to make the grinding cone block 405 quickly approach the tantalum carbide for stamping and crushing; after a single stamping, the tantalum carbide is continuously pressed in the grinding cone cylinder 402 for 10 minutes; The grinding process requires starting the servo motor 421, which drives the worm 420 to rotate after the motor is started. The rotation of the worm 420 makes the worm wheel 419 mesh, and then drives the grinding cone block 405 to rotate, so as to achieve continuous grinding of tantalum carbide. The cycle working time is 2 hours; the ground tantalum carbide is blown up by starting the blower 406, and the blower 406 compresses air and blows it into the grinding cylinder 401, so as to blow up the crushed tantalum carbide; the exhaust fan 408 is started, and the exhaust fan 408 sucks the tantalum carbide inside the grinding cylinder 401 into the suction channel 407, and after being blocked by the inner filter 409, the tantalum carbide falls into the screening box 410;

[0147] The tantalum carbide in the screening box 410 is separated by the screening net 411, and the tantalum carbide that meets the standards is discharged and collected through the discharge hopper 414; the tantalum carbide that does not pass through the screening net 411 falls into the circulation bucket 413, and the circulation bucket 413 sends the tantalum carbide to the bottom of the circulation cylinder 415, and the servo motor 417 is started, and the motor drives the circulation auger 416 to rotate, thereby realizing the circulation crushing and grinding processing of the tantalum carbide.
