Description

Technical Field

[0001] The present invention relates to the field of crushing devices, and particularly to a raw material crushing device for the production of silicon carbide ceramics. Background Art

[0002] With the development of industrial technology, modern crushing device technology has become increasingly perfect. The raw materials for the production of silicon carbide ceramics are materials such as quartz sand, petroleum coke, and wood chips. These materials need to react in an environment of two thousand degrees Celsius. These materials also need to be pretreated before use, especially the pretreatment of quartz sand. The hardness of quartz sand is relatively large, so the crushing and grinding operations of quartz sand are relatively difficult.

[0003] For example, a raw material crushing device for the production of silicon carbide ceramics disclosed in Patent No. 201610897523.X. The technical problem to be solved by the present invention is to provide a raw material crushing device for the production of silicon carbide ceramics with good crushing effect, high working efficiency, and simple structure. To solve the above technical problems, the present invention provides such a raw material crushing device for the production of silicon carbide ceramics, including a bottom plate, a left frame, a right frame, a top plate, a crushing frame, a first slide rail, a first slider, a moving frame, a first support rod, a guide sleeve, a guide rod, a first sliding shaft, etc.; the left end of the top of the bottom plate is welded with a left frame, the right end of the top of the bottom plate is welded with a right frame, and the top ends of the left frame and the right frame are welded with a top plate. The present invention achieves the effects of good crushing effect, high working efficiency, and simple structure.

[0004] This device still has defects when in use. First, the hardness of quartz sand is relatively large, and the crushing device is a metal product with a relatively hard texture. Long-term crushing operations will cause wear to the stirring blades. And if large pieces of quartz sand fall into the crushing device, it will cause a large load on the mechanical gap and lead to rigid collisions, which is likely to burn out the equipment circuit and break the stirring blades. Second, after the quartz sand and other raw materials are ground, they are powdery materials, which are more troublesome to store, and dust will be generated during the handling of the powder. Summary of the Invention

[0005] The purpose of the present invention is to provide a raw material crushing device for the production of silicon carbide ceramics in view of the deficiencies of the prior art. When the device is in use, the quartz sand material to be processed is put into the grinding box. At this time, the grinding motor drives the reduction belt and the driven pulley to rotate through the driving pulley at its output end. Then, the cover plate and the inner liner will rotate synchronously with the driven pulley. The crushing plate and the arc plate on its side wall will fit against the inner side wall of the grinding box for crushing operations. At this time, the counterweight and the pressure plunger apply pressure to the oil pressure chamber by their own gravity. The hydraulic oil applies pressure to the oil pressure cylinder through the oil pressure pipe. Then, the ejector rod will apply a torsional pressure to the rotating wheel and the extrusion wheel. When the extrusion wheel abuts against the slope plate, the pressure between the arc plate and the inner side wall of the grinding box is applied by means of oil pressure. If a large piece of quartz sand is stuffed into the gap between the arc plate and the grinding box, the oil pressure will recoil and lift the counterweight, avoiding the rigid collision between the quartz sand and the equipment.

[0006] To solve the above problems, the present invention provides the following technical solutions: A raw material crushing device for the production of silicon carbide ceramics, including a grinding box.

[0007] Further, the power torsion assembly includes a column at the top end of the cover plate. A driven pulley is arranged at the top end of the column. A driving pulley is arranged on one side of the driven pulley. The driving pulley and the driven pulley are connected by a reduction belt. A driving flange is arranged on the side wall of the grinding box. A grinding motor is arranged at the bottom end of the driving flange. The driving pulley is connected to the output end of the grinding motor.

[0008] Further, the diameter ratio of the driven pulley to the driving pulley is three to two.

[0009] Furthermore, the torque control assembly includes an oil pressure cylinder at the top end of the diverging arm. A push rod is slidably installed inside the oil pressure cylinder. The tail end of the oil pressure cylinder is hinged to the top surface of the diverging arm, and the end of the push rod is hinged to the top surface of the runner. A pressure chamber matching the push rod is arranged inside the oil pressure cylinder, and the pressure chamber is connected to an oil pressure mechanism.

[0010] Furthermore, the oil pressure mechanism includes a hydraulic block at the top end of the load-bearing vertical rod. Three groups of oil pressure chambers are arranged on the hydraulic block, and each group of oil pressure chambers consists of two. An oil pressure pipe is led out from the bottom end of the oil pressure chamber, and the oil pressure pipe is connected to the pressure chamber inside the oil pressure cylinder. A plunger assembly is arranged above the hydraulic block.

[0011] Furthermore, the plunger assembly includes a counterweight block above the hydraulic block. Three groups of pressure plungers are arranged at the bottom end of the counterweight block, and the pressure plungers are matched with the positions of the oil pressure chambers. A counterweight mechanism is arranged on the counterweight block.

[0012] Furthermore, the counterweight mechanism includes a filling groove at the top end of the counterweight block. The filling grooves are arranged in a circular and uniform manner, and columnar lead blocks are filled inside the filling grooves.

[0013] Furthermore, the material ramming assembly includes a cross plate at the top end of the ramming box. A stepping motor is arranged at the top end of the cross plate. A conical tile is arranged on the output rod of the stepping motor. Five spiral strips arranged in a circular array are arranged on the conical tile. An inlet hopper is arranged at the top end of the conical tile. The inlet hopper is butted against the bottom end port of the blanking pipe. Five blanking wire grooves are arranged on the inlet hopper, and the blanking wire grooves are butted against the gaps between the spiral strips. A spray assembly is also arranged above the conical tile, and a ramming and forming assembly is arranged below the conical tile.

[0014] Furthermore, the spray assembly includes a carrying flange at the top end of the ramming box. A water pump is arranged at the top end of the carrying flange. A water inlet pipe is arranged at the input end of the water pump, and the water inlet pipe is connected to a water source. A surrounding steel pipe is arranged at the output end of the water pump, and five atomizing nozzles are connected to the surrounding steel pipe.

[0015] Furthermore, the ramming and forming assembly includes a hydraulic press at the bottom end of the ramming box. A ramming hammer is arranged at the end of the output rod of the hydraulic press. An extrusion pipe is arranged on one side of the ramming box opposite to the hydraulic press, and the ramming hammer is aligned with the axis of the extrusion pipe.

[0016] The beneficial effects of the present invention:

[0017] First, when the device is in use, the quartz sand material to be processed is put into the grinding box. At this time, the grinding motor drives the reduction belt and the driven pulley to rotate through the driving pulley at its output end. Then, the cover plate and the inner tank will rotate synchronously with the driven pulley. The crushing plate and the arc plate on its side wall will fit against the inner side wall of the grinding box for crushing operations. At this time, the counterweight and the pressure plunger apply pressure to the oil pressure chamber due to their own gravity. The hydraulic oil applies pressure to the oil pressure cylinder through the oil pressure pipe. Then, the ejector rod applies a torsional pressure to the runner and the extrusion wheel. When the extrusion wheel abuts against the ramp plate, the pressure between the arc plate and the inner side wall of the grinding box is applied by means of oil pressure. If a large piece of quartz sand gets into the gap between the arc plate and the grinding box, the oil pressure will recoil and lift the counterweight, avoiding the rigid collision between the quartz sand and the equipment.

[0018] Second, according to the working conditions of processing quartz sand, start loading columnar lead blocks into the loading groove at the top of the counterweight. The more lead blocks are loaded, the greater the oil pressure generated by gravity will be. When loading the lead blocks, they are preferentially symmetrically loaded according to the quantity, and the pressure between the arc plate and the inner side wall of the grinding box can be automatically adjusted.

[0019] Third, remove the blocking block in the blanking pipe. The crushed powder falls from the blanking pipe into the feeding hopper. When the stepping motor drives the conical tile to rotate, the conical tile will vibrate, and the powder will evenly fall into the gap of the spiral strip from the blanking wire groove. At this time, the atomizing nozzle starts to spray out water liquid for humidification. The humidified material falls below the conical tile, and the hydraulic press drives the ramming hammer to rush out of the extrusion pipe to ram the material into columnar material, which is convenient for packaging into boxes.

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0032] Refer to Figures 1 to 8A raw material crushing device for silicon carbide ceramic production shown in the figure includes a grinding box 1. Inside the grinding box 1, an inner tank 6 is rotatably arranged. At the top of the inner tank 6, a cover plate 2 is detachably installed. The cover plate 2 is connected to a power torsion assembly. Inside the inner tank 6, a load-bearing vertical rod 7 is fixedly arranged. At the bottom end of the load-bearing vertical rod 7, there are three diverging arms 704. At the end of the diverging arm 704, there is a clamping groove, and a rotating wheel 705 is rotatably arranged in the clamping groove. On the side wall of the rotating wheel 705, there is an expanding arm, and at the end of the expanding arm, there is an extrusion wheel 706. On the side wall of the inner tank 6, there are three insertion slots. Inside the insertion slots, a crushing plate 601 is slidably installed. At the inner end of the crushing plate 601, there is a slope plate 603. The extrusion wheel 706 is attached to the side wall of the slope plate 603. Outside the inner tank 6, there is also an arc plate. The diameter of the arc plate is smaller than that of the inner tank 6. At the corner of the arc plate and the crushing plate 601, there is also a reinforcing rib 602. At the top end of the load-bearing vertical rod 7, it is connected to the extrusion wheel 706 and a torque control assembly. At the bottom end of the grinding box 1, there is a blanking pipe 102. Below the blanking pipe 102, there is a ramming box 4. On the ramming box 4, there is a material ramming assembly. The rotating wheel 705 and the extrusion wheel 706 on its side wall exert pressure on the slope plate 603. Then, the crushing plate 601 and the arc plate will exert pressure on the inner side wall of the grinding box 1. During the rotation of the inner tank 6, the gap between the arc plate and the inner side wall of the grinding box 1 will break the quartz sand. When adjusting the pressure of the extrusion wheel 706 on the slope plate 603, the gap between the arc plate and the grinding box 1 will break harder quartz sand.

[0033] As Figure 1 , 3 shown, the power torsion assembly includes a column at the top of the cover plate 2. At the top of the column, there is a driven wheel disc 301. On one side of the driven wheel disc 301, there is a driving wheel disc 302. The driving wheel disc 302 and the driven wheel disc 301 are connected by a reduction belt 303. On the side wall of the grinding box 1, there is a driving flange 101. At the bottom end of the driving flange 101, there is a grinding motor 3. The driving wheel disc 302 is connected to the output end of the grinding motor 3. The grinding motor 6 drives the reduction belt 303 and the driven wheel disc 301 to rotate through the driving wheel disc 302 at its output end. Then, the cover plate 2 and the inner tank 6 will rotate synchronously with the driven wheel disc 301. The grinding motor applies the power for crushing to the inner tank 6.

[0034] As Figure 1 , 3 shown, the diameter ratio of the driven wheel disc 301 to the driving wheel disc 302 is three to two. According to the actual situation of processing, if the resistance of the material to be ground is relatively large, then the driven wheel disc 301 is replaced with a different model. When the diameter ratio of the driven wheel disc 301 to the driving wheel disc 302 is adjusted to be larger, the driven wheel disc 301 will obtain a greater torque to crush the material.

[0035] As Figure 1 、 5 、 as shown in FIG. 6, the torque control assembly includes an oil pressure cylinder 708 at the top end of the diverging arm 704. A push rod is slidably installed inside the oil pressure cylinder 708. The tail end of the oil pressure cylinder 708 is hinged to the top surface of the diverging arm 704, and the end of the push rod is hinged to the top surface of the runner 705. A pressure chamber matching the push rod is arranged inside the oil pressure cylinder 708, and the pressure chamber is connected to an oil pressure mechanism. The pressure chamber inside the oil pressure cylinder 708 will be pressed by the push rod. The push rod pushes the runner 705 to rotate and makes the extrusion wheel on the side wall of the runner 705 apply pressure to the ramp plate 603. The way the oil pressure cylinder 708 applies pressure is oil pressure. If there are large pieces of quartz sand in the gap between the arc plate 603 and the inner wall of the grinding box 1, the oil pressure will backflush to increase the gap between the arc plate 603 and the grinding box 1, avoiding rigid collision between the quartz sand and the equipment and extending the service life of the equipment.

[0036] As Figure 1 、 6 as shown in FIG., the oil pressure mechanism includes a hydraulic block 701 at the top of the load-bearing vertical rod 7. Three groups of oil pressure chambers 709 are arranged on the hydraulic block 701, and each group of the oil pressure chambers 709 consists of two. An oil pressure pipe 707 is led out from the bottom end of the oil pressure chamber 709, and the oil pressure pipe 707 is connected to the pressure chamber inside the oil pressure cylinder 708. A plunger assembly is arranged above the hydraulic block 701. When the plunger assembly penetrates into the oil pressure chamber 709, the oil pressure chamber 709 will continuously apply pressure to the oil pressure cylinder 708.

[0037] As Figure 1 、 5 、 as shown in FIG. 6, the plunger assembly includes a counterweight block 702 above the hydraulic block 701. Three groups of pressure plungers 710 are arranged at the bottom end of the counterweight block 702, and the pressure plungers 710 are matched with the positions of the oil pressure chambers 709. A counterweight mechanism is arranged on the counterweight block 702. The way the pressure plungers 710 and the counterweight block 702 apply pressure downward is by their own gravity. If it is desired to double the pressure of the oil pressure cylinder 708, one of the two pressure plungers 710 in each group is removed, and then the pressure of the other pressure plunger 710 will increase by two times.

[0038] As Figure 1 、 6As shown, the counterweight mechanism includes a loading groove 703 at the top of the counterweight block 702. The loading grooves 703 are arranged evenly in a ring shape, and columnar lead blocks are loaded inside the loading grooves 703. According to the working condition of processing quartz sand, columnar lead blocks are loaded into the loading grooves 703 at the top of the counterweight block 702. The more lead blocks are loaded, the greater the oil pressure generated by gravity. When loading the lead blocks, they are preferentially symmetrically loaded according to the quantity, and the pressure between the arc-shaped plate and the inner wall of the grinding box can be automatically adjusted.

[0039] As Figure 1 , 7 , 8 shown, the material ramming assembly includes a cross plate 402 at the top of the ramming box 4. A stepping motor 403 is arranged at the top of the cross plate 402. A conical tile 9 is arranged on the output rod of the stepping motor 403. Five spiral strips 901 arranged in a circular array are arranged on the conical tile 9. A feed hopper 902 is arranged at the top of the conical tile 9. The feed hopper 902 is docked at the bottom port of the blanking pipe 102. Five blanking wire grooves 903 are arranged on the feed hopper 902. The blanking wire grooves 903 are docked with the gaps between the spiral strips 901. A spray assembly is also arranged above the conical tile 9, and a ramming and forming assembly is arranged below the conical tile 9. The plug block in the blanking pipe 102 is taken off, and the crushed powder falls from the blanking pipe 102 into the feed hopper 902. At this time, when the stepping motor 403 drives the conical tile 9 to rotate, the conical tile 9 will vibrate, and the powder will evenly fall into the gaps between the spiral strips 901 from the blanking wire grooves 903, and the powder will be evenly distributed on the top surface of the conical tile 9.

[0040] As Figure 1 , 8 shown, the spray assembly includes a carrying flange 401 at the top of the ramming box 4. A water pump 8 is arranged at the top of the carrying flange 401. A water inlet pipe 801 is arranged at the input end of the water pump 8. The water inlet pipe 801 is connected to a water source. A surrounding steel pipe 802 is arranged at the output end of the water pump 8. Five atomizing nozzles 803 are connected to the surrounding steel pipe 802. The water pump 8 pumps the liquid and pushes it into the atomizing nozzles 803. The atomizing nozzles 803 start to spray the liquid for humidification. The humidified material falls below the conical tile 9, and the material will come into full contact with the powder.

[0041] As Figure 1 , 7 shown, the ramming and forming assembly includes a hydraulic press 5 at the bottom of the ramming box 4. A ramming hammer is arranged at the end of the output rod of the hydraulic press 5. An extrusion pipe 501 is arranged on one side of the ramming box 4 opposite to the hydraulic press 5. The ramming hammer is aligned with the axis of the extrusion pipe 501. The hydraulic press 5 drives the ramming hammer to rush out from the extrusion pipe 501 to ram the material into columnar materials, which is convenient for packaging into boxes.

[0042] Working principle: The runner 705 and the extrusion wheel 706 on its side wall exert pressure on the ramp plate 603. Subsequently, the crushing plate 601 and the arc plate apply pressure to the inner wall of the grinding box 1. During the rotation of the inner tank 6, the gap between the arc plate and the inner wall of the grinding box 1 will break the quartz sand. When adjusting the pressure of the extrusion wheel 706 on the ramp plate 603, the gap between the arc plate and the grinding box 1 will break harder quartz sand. The grinding motor 6 drives the reduction belt 303 and the driven pulley 301 to rotate through the driving pulley 302 at its output end. Then, the cover plate 2 and the inner tank 6 will rotate synchronously with the driven pulley 301. The grinding motor applies the power of crushing to the inner tank 6. If the resistance of the material to be ground is relatively large, then replace the driven pulley 301 with different models. When the diameter ratio of the driven pulley 301 to the driving pulley 302 is adjusted larger, the driven pulley 301 will obtain a greater torque to crush the material. The pressure chamber inside the oil cylinder 708 will be pressured by the ejector rod. The ejector rod pushes the runner 705 to rotate and makes the extrusion wheel on the side wall of the runner 705 exert pressure on the ramp plate 603. The way of pressurizing the oil cylinder 708 is hydraulic pressure. If there are large pieces of quartz sand in the gap between the arc plate 603 and the inner wall of the grinding box 1, the hydraulic pressure will recoil to make the gap between the arc plate 603 and the grinding box 1 larger, avoiding rigid collision between the quartz sand and the equipment and prolonging the service life of the equipment. When the plunger assembly penetrates into the oil pressure chamber 709, the oil pressure chamber 709 will continuously exert pressure on the oil cylinder 708. The pressure plunger 710 and the counterweight 702 exert pressure downward by their own gravity. If you want to double the pressure of the oil cylinder 708, remove one of the two pressure plungers 710 in each group. Then, the pressure of the other pressure plunger 710 will increase by two times. According to the working conditions of processing quartz sand, start loading columnar lead blocks into the loading groove 703 at the top of the counterweight 702. The more lead blocks are loaded, the greater the oil pressure generated by gravity will be. When loading the lead blocks, they are preferentially symmetrically loaded according to the quantity. The pressure between the arc plate and the inner wall of the grinding box can be automatically adjusted. Remove the block in the blanking pipe 102. The crushed powder falls from the blanking pipe 102 into the feeding hopper 902. At this time, when the stepping motor 403 drives the conical tile 9 to rotate, the conical tile 9 will vibrate, and the powder will evenly fall into the gap of the spiral strip 901 from the blanking wire groove 903. The powder will be evenly distributed on the top surface of the conical tile 9. The water pump 8 pumps the water liquid and pushes it into the atomizing nozzle 803. The atomizing nozzle 803 starts to spray the water liquid for humidification. The humidified material falls below the conical tile 9. The material will come into full contact with the powder. The hydraulic press 5 drives the ramming hammer to rush out from the extrusion pipe 501 to ram the material into columnar material for easy packaging into the box.

[0043] As described above, it is only the preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
