Description

Technical Field

[0001] The invention relates to the technical field of inorganic nano material processing, in particular to a pulverizing device and a pulverizing method for inorganic nano material processing. Background Art

[0002] Inorganic nanomaterials are nanoscale materials composed of inorganic substances, whose structural units are smaller than 100 nanometers in at least one dimension. They need to be crushed when processed.

[0003] For example, a pulverizing device for processing nanomaterials with the announcement number CN219596731U is provided in a housing to extrude the raw material first, and the raw material is pulverized by entering the pulverizing component provided below the pulverizing component in the second process. The raw material is pulverized and screened out by the grinding unit in the third process, thereby achieving the pulverization of the nano raw material, making the particle size of the processed nano raw material uniform and uniform, and improving the production quality of the product. However, in actual use, the material is crushed and pulverized by the grinding roller, and the grinding roller can only move in one direction. When the material falls on the screen plate and slightly accumulates, the grinding roller cannot fully crush the accumulated material in one movement. The accumulated material will be pushed to the top and sides of the screen plate as the grinding roller moves, and the material will be pushed to the moving dead corner of the grinding roller, which will cause waste of material. If a pushing structure is added at the dead corner, although the material can be pushed out, the material will still accumulate on the top and sides of the screen plate after being pushed out. When the accumulated material is crushed again, only a small part of the material can be crushed, which will increase the crushing time and reduce the efficiency of the full crushing of the material. There are certain use defects.

[0004] Therefore, we propose a pulverizing device and a pulverizing method for inorganic nanomaterial processing in order to solve the above-mentioned problems. Summary of the invention

These accumulated materials will be pushed to the top sides of the screen plate as the grinding roller moves, and the materials will be pushed to the dead corner of the grinding roller, which will cause material waste. If a pushing structure is added at the dead corner, although the material can be pushed out, the material will still accumulate on the top sides of the screen plate after being pushed out. When the accumulated material is crushed again, only a small part of the material can be crushed, which will increase the crushing time and reduce the efficiency of sufficient material crushing.

[0020] By adopting the above technical solution, the belt can be tensioned to avoid the belt from loosening after movement, thereby avoiding affecting the transmission of the first pulley to the second pulley.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the pulverizing device and pulverizing method for processing inorganic nanomaterials are provided with pulverizing components inside and outside the pulverizing box, so that when the inorganic nanomaterials are pulverized, it can be avoided that when the materials are piled up on the screen plate, the rolling wheel can only move in one direction, and it is avoided that the rolling wheel cannot cross the piled materials after moving, and then the piled materials will be pushed to the top two sides of the screen plate, and the materials will be pushed to the rolling dead angle of the rolling wheel, so as to avoid affecting the pulverization quality and pulverization efficiency of the materials; 1. When crushing inorganic nanomaterials, the materials are put into the crushing box through the feed port, and the driving motor is started to drive the rotating shaft on one side to rotate. Then, the two rotating shafts rotate synchronously through the mutual engagement of the two rotating gears, and the materials are preliminarily crushed by the two crushing rollers. Then, the materials can fall on the top of the screen plate through the guide plate, and the rear rotating shaft can drive the two-way spiral blades to rotate through the cooperation of the third pulley and the fourth pulley during the rotation process. The materials after the preliminary crushing can fall on the two guide plates, and the materials can be pushed to both sides by the two-way spiral blades, so that the falling range of the materials can be expanded, so that the materials fall evenly on the top of the screen plate. While the front rotating shaft rotates, the reciprocating screw can be driven to rotate through the cooperation of the first pulley and the second pulley. After the reciprocating screw rotates, it can drive the movable sleeve to move back and forth, so that the rolling wheel moves back and forth. The rolling wheel moves during the movement process. The middle driving positioning sleeve slides outside the guide rod, so that the rolling wheel can fully crush the material, and when the rolling wheel rolls over the material, if the material is piled up, the rolling wheel can move slightly upward during the left and right reciprocating movement, so that the movable rod is driven to slide on the fixed block, and the telescopic spring is always in a compressed state, which can ensure that the rolling wheel and the material on the screen plate are closely fitted, and the rolling wheel drives the eccentric wheel to rotate during the rotation process. The centrifugal force brought by the rotation of the eccentric wheel can increase the downward pressure of the rolling wheel, improve the material crushing efficiency, so that the crushed material can fall through the screen plate and then be discharged through the discharge port, so as to avoid the rolling wheel only being able to move in one direction when encountering material accumulation, so as to avoid the rolling wheel being unable to cross the accumulated material after moving, and then pushing the accumulated material to the top two sides of the screen plate, and pushing the material to the rolling dead corner of the rolling wheel, so as to avoid affecting the material crushing quality and crushing efficiency; 2. The rolling wheel may push a small amount of material to both sides of the top of the screen plate during its left and right reciprocating movement. The rolling wheel will drive the positioning rod to move upward during its upward movement. After the positioning rod moves upward, it pulls the rubber rope to move. After the rubber rope moves, it can pull the rotating rod through the fixed rod to rotate. After the rotating rod rotates, it drives the push rod to rotate. After the push rod rotates, it can push the push plate to move through the roller. After the push plate moves, it can push the materials on both sides of the top of the screen plate. If the rolling wheel happens to move to one side of the push plate after the push plate moves, the push plate conflicts with the rolling wheel. The upward movement of the positioning rod can stretch the rubber rope, so that the positioning rod can still move upward after the push plate conflicts with the rolling wheel, and the material in the dead corner of the rolling can be pushed out to avoid material waste. 3. When the crushing wheel is crushing and the reciprocating screw rod and the guide rod are moving upward, the belt at the connection between the first pulley and the second pulley will be loosened to a certain extent. When the loosening occurs, the compression spring is in a compressed state, so that the movable rod can be driven to slide on the fixed frame, so that the tensioning wheel on the movable frame is tightly fitted with the belt at the connection between the first pulley and the second pulley. The belt can be tensioned by the tensioning wheel to avoid the belt from loosening after the movement, so as to avoid affecting the transmission of the first pulley to the second pulley.

[0026] Embodiment 1: Figure 1-Figure 5As shown, when the inorganic nanomaterial is crushed, the material is put into the crushing box 1 through the feed port 102, and the driving motor 203 is started to drive the rotating shaft 201 on one side to rotate. Then, the two rotating shafts 201 are rotated synchronously through the mutual engagement of the two rotating gears 204, and the material is preliminarily crushed by the two crushing rollers 205. Then, the material can fall on the top of the screen plate 104 through the guide plate 206, and the rear rotating shaft 201 can drive the bidirectional screw during the rotation process through the cooperation of the third pulley 222 and the fourth pulley 223.

The bidirectional spiral blade 221 can push the material to both sides, so that the falling range of the material can be expanded, so that the material falls evenly on the top of the screen plate 104. When the front rotating shaft 201 rotates, the reciprocating screw rod 213 can be driven to rotate through the cooperation of the first pulley 208 and the second pulley 2131. After the reciprocating screw rod 213 rotates, it can drive the movable sleeve 214 to reciprocate, so that the rolling wheel 217 can reciprocate, and the rolling wheel 21 During the movement, the positioning sleeve 216 is driven to slide outside the guide rod 215, so that the rolling wheel 217 can fully crush the material. When the rolling wheel 217 rolls over the material, if the material is piled up, the rolling wheel 217 can move slightly upward during the left and right reciprocating movement, so as to drive the movable rod 210 to slide on the fixed block 209, and the telescopic spring 212 is always in a compressed state, which can ensure that the rolling wheel 217 is closely fitted with the material on the screen plate 104, and the rolling wheel 217 drives the eccentric wheel 220 to rotate during the rotation process.

[0027] Two sets of sliding rods 224 are respectively slidably connected to the crushing box 1 below one side of the two sets of support blocks 211, and a return spring 225 is sleeved on one side of the outer side of the sliding rod 224, and the two ends of the return spring 225 are respectively fixedly connected to the crushing box 1 and the sliding rod 224, and a push plate 226 is fixedly installed at one end of each set of two sliding rods 224; Positioning rods 227 are fixedly installed between the left and right groups of support blocks 211, and rotating rods 228 are symmetrically rotatably connected to the top of the screen plate 104, and a fixing rod 229 is fixedly installed on the outer upper part of the rotating rod 228, and a rubber rope 230 is fixedly installed on the top of the fixing rod 229, and the elastic potential energy of the rubber rope 230 is greater than the elastic potential energy of the two return springs 225, and the end of the rubber rope 230 away from the fixing rod 229 is fixedly connected to the positioning rod 227; A push rod 231 is fixedly installed at the lower part of the outer portion of the rotating rod 228 , and one end of the push rod 231 is rotatably connected to a roller 232 , and the roller 232 is rotatably connected to the push plate 226 .

[0028] Embodiment 2: Figure 2-Figure 4 and Figure 6-Figure 7 As shown, the rolling wheel 217 may push a small amount of material to both sides of the top of the screen plate 104 during the reciprocating movement. The rolling wheel 217 will drive the positioning rod 227 to move upward during the upward movement. After the positioning rod 227 moves upward, it pulls the rubber rope 230 to move. After the rubber rope 230 moves, it can pull the rotating rod 228 to rotate through the fixed rod 229. After the rotating rod 228 rotates, it drives the push rod 231 to rotate. After the push rod 231 rotates, it can push the push plate through the roller 232 226 moves, and the push plate 226 can push the materials on both sides of the top of the screen plate 104 after it moves. If the rolling wheel 217 happens to move to one side of the push plate 226 after the push plate 226 moves, the push plate 226 will conflict with the rolling wheel 217, and the upward movement of the positioning rod 227 can stretch the rubber rope 230, so that the positioning rod 227 can still move upward after the push plate 226 conflicts with the rolling wheel 217, and the material in the dead corner of the crushing can be pushed out to avoid waste of material.

[0029] A tensioning assembly 3 is arranged on one side of the outside of the crushing box 1; The tensioning assembly 3 includes a fixed frame 301 fixedly installed above one side of the crushing box 1, and a moving rod 302 is symmetrically slidably connected to the inner side of the fixed frame 301, and a movable frame 303 is fixedly installed at one end of the two moving rods 302, and a compression spring 304 is sleeved on the outer side of the two moving rods 302, and the two ends of the compression spring 304 are respectively fixedly connected to the fixed frame 301 and the movable frame 303, and a tensioning wheel 305 is rotatably connected to the inner side of the movable frame 303, and the tensioning wheel 305 is rotatably connected to the belt at the connection between the first pulley 208 and the second pulley 2131.

[0030] Embodiment 3: Figure 1 and Figure 8-Figure 9As shown, when the crushing wheel 217 is crushing and the reciprocating screw rod 213 and the guide rod 215 are moving upward, the belt at the connection between the first pulley 208 and the second pulley 2131 will be loosened to a certain extent. When the loosening occurs, the compression spring 304 is in a compressed state, so that the movable rod 302 can be driven to slide on the fixed frame 301, so that the tensioning wheel 305 on the movable frame 303 is tightly fitted with the belt at the connection between the first pulley 208 and the second pulley 2131. The tensioning wheel 305 can be used to tension the belt to avoid loosening of the belt after movement, so as to avoid affecting the transmission of the first pulley 208 to the second pulley 2131.

[0031] Working principle: When using the pulverizing device for inorganic nanomaterial processing, first, according to Figure 1-Figure 9 As shown, when the inorganic nanomaterial is crushed, the material is put into the crushing box 1 through the feed port 102, and the driving motor 203 is started to drive the rotating shaft 201 on one side to rotate. Then, the two rotating shafts 201 are synchronously rotated through the mutual engagement of the two rotating gears 204, and the material is preliminarily crushed by the two crushing rollers 205. Then, the material can fall on the top of the screen plate 104 through the guide plate 206, and the rear rotating shaft 201 can drive the bidirectional spiral blade 221 to rotate through the cooperation of the third pulley 222 and the fourth pulley 223 during the rotation process. The material after the preliminary crushing can fall on the two guide plates 206, and the bidirectional spiral blade 221 can push the material to both sides, so that the falling range of the material can be expanded, so that the material falls evenly on the top of the screen plate 104, and the front rotating shaft 201 can be driven to rotate through the cooperation of the first pulley 208 and the second pulley 2131 while the front rotating shaft 201 rotates. The multiple-thread rod 213 rotates, and after the reciprocating thread rod 213 rotates, it can drive the movable sleeve 214 to reciprocate, so that the rolling wheel 217 reciprocates. During the movement, the rolling wheel 217 drives the positioning sleeve 216 to slide outside the guide rod 215, so that the rolling wheel 217 can fully crush the material. When the rolling wheel 217 rolls over the material, if the material is piled up, the rolling wheel 217 can move slightly upward during the left and right reciprocating movement, so as to drive the movable rod 210 to slide on the fixed block 209, and the telescopic spring 212 is always in a compressed state, which can ensure that the rolling wheel 217 is closely fitted with the material on the screen plate 104, and the rolling wheel 217 drives the eccentric wheel 220 to rotate during the rotation. The centrifugal force brought by the rotation of the eccentric wheel 220 can increase the downward pressure of the rolling wheel 217, improve the material crushing efficiency, so that the crushed material can fall through the screen plate 104 and then be discharged through the discharge port 103; The rolling wheel 217 may push a small amount of material to both sides of the top of the screen plate 104 during its left and right reciprocating movement. The rolling wheel 217 will drive the positioning rod 227 to move upward during its upward movement. After the positioning rod 227 moves upward, it will pull the rubber rope 230 to move. After the rubber rope 230 moves, it can pull the rotating rod 228 through the fixed rod 229 to rotate. After the rotating rod 228 rotates, it drives the push rod 231 to rotate. After the push rod 231 rotates, it can push the push plate 226 to move through the roller 232. After the push plate 226 moves, it can push the materials on both sides of the top of the screen plate 104. If the rolling wheel 217 happens to move to one side of the push plate 226 after the push plate 226 moves, the push plate 226 will conflict with the rolling wheel 217, and the upward movement of the positioning rod 227 can stretch the rubber rope 230, thereby The positioning rod 227 can still move upward after the push plate 226 conflicts with the grinding wheel 217, and then the material in the grinding dead corner can be pushed out to avoid material waste. When the grinding wheel 217 is grinding and crushing, the reciprocating screw rod 213 and the guide rod 215 move upward, and the belt at the connection between the first pulley 208 and the second pulley 2131 will be loosened to a certain extent. When the loosening occurs, the compression spring 304 is in a compressed state, so that the moving rod 302 can be driven to slide on the fixed frame 301, so that the tensioning wheel 305 on the movable frame 303 is tightly fitted with the belt at the connection between the first pulley 208 and the second pulley 2131. The belt can be tensioned by the tensioning wheel 305 to avoid the belt from loosening after the movement, so as to avoid affecting the transmission of the first pulley 208 to the second pulley 2131.

9. A pulverizing method of a pulverizing device for inorganic nanomaterial processing, using a pulverizing device for inorganic nanomaterial processing as claimed in any one of claims 1 to 8, the pulverizing method is as follows: Step 1: When the inorganic nanomaterial is crushed, the material is put into the crushing box (1) through the feed port (102), the driving motor (203) is started to drive the rotating shaft (201) on one side to rotate, and then the two rotating shafts (201) are rotated synchronously by the mutual meshing of the two rotating gears (204), and the material is initially crushed by the two crushing rollers (205), and then the material falls on the top of the screen plate (104) through the guide plate (206), and the rear rotating shaft (201) drives the two rotating shafts (201) to rotate through the cooperation of the third belt pulley (222) and the fourth belt pulley (223). The spiral blade (221) rotates, and the material after preliminary crushing falls on the two guide plates (206). The bidirectional spiral blade (221) pushes the material to both sides, thereby expanding the falling range of the material, so that the material falls evenly on the top of the screen plate (104). While the front rotating shaft (201) rotates, the reciprocating screw rod (213) is driven to rotate through the cooperation of the first pulley (208) and the second pulley (2131). After the reciprocating screw rod (213) rotates, it drives the movable sleeve (214) to reciprocate, so that the rolling wheel (217) reciprocates. 17) during the movement, the positioning sleeve (216) is driven to slide outside the guide rod (215), so that the rolling wheel (217) can fully crush the material. When the rolling wheel (217) rolls over the material, if the material is piled up, the rolling wheel (217) moves slightly upward during the left-right reciprocating movement, so that the movable rod (210) is driven to slide on the fixed block (209), and the telescopic spring (212) is always in a compressed state, so as to ensure that the rolling wheel (217) and the material on the screen plate (104) are closely fitted. The rolling wheel (217) drives the eccentric wheel (217) during the rotation process. The eccentric wheel (220) rotates, and the centrifugal force brought by the rotation of the eccentric wheel (220) increases the downward pressure of the rolling wheel (217), thereby improving the material crushing efficiency, so that the crushed material falls through the screen plate (104) and is then discharged through the discharge port (103), thereby preventing the rolling wheel (217) from being able to move in only one direction when encountering material accumulation, thereby preventing the rolling wheel (217) from being unable to cross the accumulated material after moving, and then pushing the material to the top sides of the screen plate (104), pushing the material to the rolling dead corner of the rolling wheel (217), thereby preventing the crushing quality and crushing efficiency of the material from being affected; Step 2: The rolling wheel (217) pushes a small amount of material to both sides of the top of the screen plate (104) during the reciprocating movement. The rolling wheel (217) drives the positioning rod (227) to move upward during the upward movement. After the positioning rod (227) moves upward, it pulls the rubber rope (230) to move. After the rubber rope (230) moves, it pulls the rotating rod (228) through the fixed rod (229) to rotate. After the rotating rod (228) rotates, it drives the push rod (231) to rotate. After the push rod (231) rotates, it pushes the push plate through the roller (232). (226) moves, and after the push plate (226) moves, it pushes the materials on both sides of the top of the screen plate (104). If the rolling wheel (217) just moves to one side of the push plate (226) after the push plate (226) moves, the push plate (226) and the rolling wheel (217) collide with each other, and the upward movement of the positioning rod (227) stretches the rubber rope (230), so that after the push plate (226) and the rolling wheel (217) collide with each other, the positioning rod (227) still moves upward, and the materials in the rolling dead corner are pushed out, thereby avoiding waste of materials; Step 3: When the crushing wheel (217) is crushing and pulverizing, the reciprocating screw rod (213) and the guide rod (215) are moved upward, and the belt at the connection between the first pulley (208) and the second pulley (2131) will become loose. When the belt becomes loose, the compression spring (304) is in a compressed state, so that the movable rod (302) is driven to slide on the fixed frame (301), so that the tensioning wheel (305) on the movable frame (303) and the belt at the connection between the first pulley (208) and the second pulley (2131) are closely fitted, and the belt is tensioned by the tensioning wheel (305) to prevent the belt from becoming loose after the movement, thereby preventing the transmission of the first pulley (208) to the second pulley (2131) from being affected.
