[0015] The crushing device for feldspar ore treatment of the present invention has the following advantages: 1. During the crushing treatment of feldspar ore by this crushing device for feldspar ore treatment, a unified driving source is provided by the servo motor. While the four planetary gears are driven to rotate synchronously by the intermediate gear, the four planetary gears also drive the double-sided gear ring to rotate accordingly.

[0016] 2. Secondly, by this crushing device for feldspar ore treatment, the double-sided gear ring drives the two differential gears to rotate. The two differential gears drive the reciprocating lead screws on the two secondary bevel gears to rotate through the two main bevel gears. The two reciprocating lead screws drive the two main extrusion racks to perform reciprocating inward and outward movement through the connecting pieces on the two screw sleeves, and with the cooperation of the extrusion teeth on the two secondary extrusion racks, the two main extrusion racks perform comprehensive extrusion and crushing treatment on the passing feldspar through the extrusion heads, further improving the crushing efficiency of feldspar.

[0017] 3. For the crushing device for feldspar ore treatment, immediately afterwards, the main crushing tooth roller drives the turbine fan to rotate in the air blower frame and generate air pressure. At the same time, the cold and heat integrated machine is pre-controlled to alternately supply cold and heat sources into the air blower frame through the conveying cover. Under the action of the air pressure, the alternately supplied cold and heat sources are forced to pass through the four groups of rotating ends and connecting ends in sequence and be supplied into the hollow cavities of the four secondary crushing tooth rollers, and then conducted to the feldspar crushing area. Under the alternating change of the cold and heat sources, according to the physical principle of thermal expansion and contraction, during the feldspar crushing, due to the sudden heating and cooling of the temperature, the structure becomes unstable and explodes, which is conducive to the rapid and sufficient crushing work of the feldspar. And the heat source generated by the cold and heat integrated machine is sent to the heat collecting cavity through the heat collecting cover by the conveying pipe to heat and dry the feldspar in the wet grinding box in the grinding state.

[0018] 4. For the crushing device for feldspar ore treatment, then, the four groups of planetary gears drive the four groups of dust exhaust fans to rotate in the four groups of buffer frames and generate negative pressure suction. Under the action of the negative pressure suction, the dust generated by the feldspar crushing in the area of the four secondary crushing tooth rollers is forced to be adsorbed into the negative pressure cavity through the dust suction holes, and then the original route passes through the four groups of buffer frames and into the dust exhaust pipes on the four groups of dust collecting covers. Under the action of its air pressure, the dust supplied into the dust exhaust pipes is supplied into the filter on the three-way valve for dust removal treatment, so as to prevent the dust generated by the feldspar crushing from overflowing everywhere and realize the functions of dust collection and dust removal.

[0019] 5. For the crushing device for feldspar ore treatment, finally, the air pressure supplied into the dust exhaust pipe also reaches the five-way valve, and the water source is supplied by the liquid storage pot. Under the action of the air pressure, the water source in the liquid storage pot is forced to be supplied into the two booster pipes while providing the conditions of humid cooling and flushing and cleaning for the grinding of the feldspar fragments. One group of differential gears drives the main grinding roller on the main circular gear to grind the feldspar reaching the wet grinding box, and the main circular gear drives the secondary grinding rollers on the two secondary circular gears to grind the feldspar in cooperation. The water source in the two booster pipes is sprayed from the spray holes to the grinding areas of the main grinding roller and the two secondary circular gears, reducing the grinding temperature of the feldspar, achieving an efficient wet grinding effect on the feldspar, and at the same time playing the roles of spraying dust reduction and flushing and cleaning.

The double-sided gear ring 74 drives the two groups of differential gears 81 to rotate. The outer sides of the differential gears 81 are fixedly connected with main bevel gears 82 through short rods. The inner sides of the main bevel gears 82 are meshed with driven bevel gears 83 fixedly matched with the forward and reverse reciprocating lead screws 84. The two groups of differential gears 81 drive the forward and reverse reciprocating lead screws 84 on the two groups of driven bevel gears 83 to rotate through the two groups of main bevel gears 82; Both sides of the forward and reverse reciprocating lead screw 84 are threadedly connected with lead screw sleeves 85. The inner sides of the lead screw sleeves 85 are fixedly connected with connectors 86 slidably matched with the crushing box 1. The inner sides of the connectors 86 are fixedly connected with main extrusion frames 87 used in cooperation with the secondary crushing tooth rollers 77. The two forward and reverse reciprocating lead screws 84 drive the two groups of main extrusion frames 87 to perform reciprocating inward and outward movements through the connectors 86 on the two groups of lead screw sleeves 85.

Under the alternating change of the cold and heat sources, according to the physical principle of thermal expansion and contraction, during the feldspar crushing, due to the sudden heat and cold, the structure is unstable and explodes, which is beneficial to the rapid and sufficient crushing work of the feldspar. The heat source generated by the cold and heat integrated machine 93 is delivered to the heat collecting cavity 97 through the conveying pipe 95 and the heat collecting cover 96 to heat and dry the feldspar in the wet grinding box 3 in the grinding state; The blast blower frame 5 is connected with a rotating end 18 near one side of the crushing tooth roller 76, and a connecting end 19 that is connected and cooperates with the hollow cavity 94 is connected near the side of the crushing tooth roller 76 close to the blast blower frame 5 and rotates with the rotating end 18.

Injection holes 22 are obliquely formed at one end of the pressurizing pipes 113 close to the main rolling roller 115 and the auxiliary rolling rollers 117. The main rolling roller 115 on the main circular gear 114 driven by one set of differential gears 81 grinds the feldspar that reaches the wet grinding box 3, and the main circular gear 114 drives the auxiliary rolling rollers 117 on the two sets of auxiliary circular gears 116 to perform combined grinding on the feldspar. The water sources in the two pressurizing pipes 113 are sprayed to the grinding areas of the main rolling roller 115 and the two sets of auxiliary circular gears 116 through the injection holes 22, reducing the grinding temperature of the feldspar, achieving an efficient wet grinding effect on the feldspar, and at the same time playing a role in spraying dust reduction and flushing and cleaning.

[0029] As Figures 18 - 19 shown, after the feldspar is crushed, most of the feldspar fragments are manually fed. While the crushed feldspar fragments cannot be guided and discharged, the effect of filtering and returning the feldspar fragments cannot be achieved, resulting in large-volume feldspar fragments blocking the discharge port, which is not conducive to the feeding work. At the same time, due to the existence of large-volume feldspar fragments, the crushing effect of the feldspar is also reduced. Feeding components that are used in combination with the extrusion components are arranged on both sides of the inner cavity of the wet grinding box 3. And the feeding components include drive gears 121 fixed at both ends of one of the forward and reverse reciprocating lead screws 84. The outer sides of the drive gears 121 mesh with bevel gear frames 122, and the outer sides of the bevel gear frames 122 mesh with driven gears 123. One of the forward and reverse reciprocating lead screws 84 drives the two drive gears 121 to rotate, and the two drive gears 121 successively drive the two bevel gear frames 122 and the driven gears 123 to rotate accordingly; A feeding auger 124 that is fixedly connected to the inner cavity of the driven gear 123 and is rotationally matched with the wet grinding box 3 is provided. A filter rack 125 for filtering and sorting feldspar fragments is embedded in the inner cavity of the feeding auger 124. Two groups of driven gears 123 drive two feeding augers 124 to convey large-volume feldspar fragments upward to the crushing box 1 for re-feeding and crushing. Small-volume feldspar fragments fall from the filter rack 125 to the area of the wet grinding box 3 near the discharge pipe 4. A guiding vane 126 that is used in cooperation with the discharge pipe 4 is fixedly connected to the bottom of the feeding auger 124. A filter plate 127 for filtering and intercepting feldspar fragments is embedded on one side of the wet grinding box 3 near the discharge pipe 4. A baffle plate that is opened and closed in cooperation with the filter plate 127 is embedded in the discharge pipe 4. After the baffle plate is opened, the guiding vane 126 that rotates synchronously with the two feeding augers 124 discharges the small-volume feldspar fragments through the filter plate 127 and out of the discharge pipe 4, while the large-volume feldspar fragments are intercepted by the filter plate 127 and then conveyed upward to the crushing box 1 by the two feeding augers 124 for re-feeding and crushing. While achieving the effect of quickly guiding and discharging the feldspar fragments, it also conveys and re-feeds the large-volume feldspar fragments for re-crushing treatment, avoiding the accumulation of large-volume feldspar fragments in the area of the discharge pipe 4 and affecting the discharging work.

[0030] Working principle of a crushing device for feldspar ore treatment: First, pour the feldspar to be crushed into the filtering grille 23 area at the uppermost layer inside the crushing box 1 through the feed hopper 2. While controlling the servo motor 71 to start and drive the transfer gear 72 to rotate, the transfer gear 72 also drives the main crushing tooth roller 75 to rotate accordingly. While the transfer gear 72 drives the four planetary gears 73 to rotate synchronously, the four planetary gears 73 also drive the four secondary crushing tooth rollers 76 to rotate accordingly. With the annular slide rail 13 and the support slide seat 14 providing rotational support and cooperation for the double-sided gear ring 74, the four planetary gears 73 drive the double-sided gear ring 74 to rotate accordingly. The double-sided gear ring 74 drives the differential gears 81 at the upper and lower positions to rotate. The two differential gears 81 drive the reciprocating lead screws 84 on the two secondary bevel gears 83 to rotate through the two main bevel gears 82. The two reciprocating lead screws 84 drive the two screw sleeves 85 to perform reciprocating inward and outward movements. The two screw sleeves 85 drive the extrusion heads 15 on the two main extrusion frames 87 to perform reciprocating inward and outward movements through the two connecting pieces 86. During this period, with the cooperation of the extrusion teeth 17 staggered on the two secondary extrusion frames 16, first, the two main extrusion frames 87 in the upper area pre-extrude and crush the feldspar in the filtering grille 23 area at the uppermost layer through the extrusion heads 15. After the feldspar fragments are pre-extruded and crushed, they pass through the uppermost filtering grille 23 to reach the crushing area of the middle filtering grille 23. With the auxiliary biting and cooperation of the four secondary crushing tooth rollers 77, the main crushing tooth roller 75 also successively drives the four secondary crushing tooth rollers 76 and the secondary crushing tooth rollers 77 to comprehensively crush the feldspar fragments after the extrusion and crushing treatment. After passing through the middle filtering grille 23 and reaching the area of the lowermost filtering grille 23, the two main extrusion frames 87 in the lower area then re-extrude and crush the feldspar in the area of the lowermost filtering grille 23 through the extrusion heads 15. The feldspar fragments after two-stage extrusion and crushing and one-stage biting and crushing pass through the lowermost filtering grille 23 and reach the grinding area of the wet grinding box 3; During this period, the main crushing tooth roller 75 drives the turbine fan 91 to rotate in the air blowing frame 5 to generate air pressure, and the cold and heat integrated machine 93 is controlled to start in advance, and the generated cold source and heat source are alternately supplied into the air blowing frame 5 through the conveying cover 92. Under the action of the air pressure, the alternately supplied cold source and heat source are forced to pass through the four groups of rotating ends 18 and the connecting ends 19 in sequence and reach the hollow cavities 94 in the four secondary crushing tooth rollers 76, and then conduct to the crushing areas of the four secondary crushing tooth rollers 76 for the feldspar. Provide alternating cold and heat changes for the feldspar in the crushing state. Under the conditions of sudden heating and sudden cooling, and according to the physical principle of thermal expansion and contraction, the internal structural stability of the feldspar is damaged, so that the feldspar explodes quickly, reducing the crushing difficulty of the feldspar. At the same time, the four groups of planetary gears 73 also drive the four groups of dust exhaust fans 101 to rotate in the four groups of buffer frames 6 to generate negative pressure. The negative pressure generated in the four groups of buffer frames 6 passes through the four groups of rotary joints 20 and the connecting joints 21 in sequence and reaches the negative pressure cavities 102 in the four secondary crushing tooth rollers 77. Under the action of the negative pressure suction, the dust generated around the four secondary crushing tooth rollers 77 due to the crushing of the feldspar returns to the four groups of buffer frames 6 along the original path through the dust suction holes 103, and then is discharged into the filters 107 on the two three-way valves 106 through the dust exhaust pipes 105 on the four groups of dust collection covers 104, and the dust collected in the four groups of buffer frames 6 is filtered. And because the dust is negatively adsorbed and the exhaust wind force is realized at the end of the conveying of the two dust exhaust pipes 105, and the exhaust air pressure generated at the end of the two dust exhaust pipes 105 is supplied into the five-way valve 111, at the same time, the clean water in the liquid storage pot 112 is controlled to be supplied into the five-way valve 111, and then under the boosting cooperation of the two boosting pipes 113, the clean water is sprayed to the grinding areas of the main rolling roller 115 and the two secondary rolling rollers 117 through the spray holes 22, providing humid cooling conditions and spray dust reduction measures for the grinding of the feldspar fragments, and also flushing and cleaning the feldspar powder attached to the grinding areas of the main rolling roller 115 and the two secondary rolling rollers 117 to prevent the adhesion of the feldspar powder. At the same time, the main rolling roller 115 on the main circular gear 114 is driven to rotate by the differential gear 81 located below, and the main circular gear 114 drives the secondary rolling rollers 117 on the two secondary circular gears 116 to rotate accordingly. Then, the main rolling roller 115 and the two secondary rolling rollers 117 perform full wet rolling treatment on the crushed feldspar fragments; After the feldspar fragments are fully wet-milled, the two drain pipes 26 are used to discharge the waste liquid accumulated in the wet-milling box 3, and the feldspar fragments are still in the wet-milling box 3. At the same time, the hot and cold integrated machine 93 is controlled to generate heat source and is supplied to the heat collecting chamber 97 in the heat collecting cover 96 through the conveying pipe 95, and then the heat source is conducted to the wet-milling box 3. While the wet-milled feldspar fragments are heated and dried, one of the forward and reverse reciprocating screw rods 84 drives the two sets of driving gears 121 to rotate, and the two sets of driving gears 121 drive the feeding augers 124 on the two sets of driven gears 123 to rotate through the two bevel gear racks 122, and the two feeding augers 124 drive the two The group of guide blades 126 rotates and the wet-milled feldspar fragments are filtered by the filter plate 127 in the discharge channel area and discharged through the discharge pipe 4, and the large-volume feldspar fragments are intercepted. The large-volume feldspar fragments are then transported upward by the two feeding augers 124 and supplied to the crushing box 1 through the return channel for full crushing processing. During this period, the two feeding augers 124 transport the large-volume feldspar fragments upward, while the small-volume feldspar fragments entrained will still fall into the discharge channel area after passing through the filter frame 125. Similarly, the two groups of guide blades 126 guide the material for discharge, and so on, until the feldspar is completely crushed and wet-milled.
