Description

Technical Field

[0001] The invention relates to the technical field of quartz sand processing, in particular to a quartz sand washing crusher. Background Art

[0002] Existing quartz sand processing usually needs to go through core links such as secondary crushing, screening, and cleaning. In the conventional process, crushing and cleaning are mostly independent processes. The quartz sand after secondary crushing needs to be transported to the cleaning equipment through additional conveying equipment, and there is an obvious process connection fault problem; the quartz sand particles after secondary crushing vary greatly in size, and need to be classified through the screening link, and then the large-particle quartz sand is sent back to the crushing equipment to be crushed to the appropriate particle size, which increases the workload; in the cleaning link, spiral sand washing machines, drum sand washing machines and trough-type scrubbing machines are mostly used. Such equipment adopts a single immersion, flushing or spraying method. During the water and cleaning process, it is usually washed once, that is, the quartz sand is always immersed in muddy sewage during the cleaning process. When it is output, a small amount of sewage will still adhere to the surface of the quartz sand. Although most of the surface water will be removed by the vibrating screen, a small amount of sludge will remain on the sand surface, causing secondary pollution of the quartz sand, which ultimately leads to low overall processing efficiency, high cost and difficulty in ensuring product purity.

[0029] The present invention will be described in further detail below with reference to the accompanying drawings.

[0030] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 6As shown, a quartz sand water-washing crusher includes a frame 1, a lower cleaning box 7 is provided on the frame 1, a screw conveyor 8 is provided inside the lower cleaning box 7, a top plate 11 is provided on the top of the frame 1, a pre-cleaning box 2 is provided at the bottom of the top plate 11, a feeding mechanism 6 is provided between the lower cleaning box 7 and the pre-cleaning box 2, a guide mechanism 3 and a crushing mechanism 4 are provided at the pre-cleaning box 2, the guide mechanism 3 includes a driver 1 31 and a guide turntable 32, the guide turntable 32 is rotatably suspended at the bottom of the top plate 11, the driver 1 31 drives the guide turntable 32 to rotate inside the pre-cleaning box 2, the crushing mechanism 4 includes a driver 2 41 and a crushing cone 42, the driver 2 41 drives the crushing cone 42 to rotate in the pre-cleaning box 2, a feeding table 12 is provided on the top plate 11, the feeding mechanism 6 transports the material inside the pre-cleaning box 2 to the lower cleaning box 7, and the screw conveyor 8 transports the material out of the lower cleaning box 7.

[0031] In the quartz sand processing process, we often face the problem of uneven particle size after secondary crushing and poor connection between cleaning and crushing, which leads to low processing efficiency. The quartz sand washing and crushing machine effectively solves the above problems through the integrated design of pre-cleaning, crushing and deep cleaning structure, and realizes efficient purification of quartz sand and regular particle size.

[0032] When the equipment is working, the quartz sand raw material after secondary crushing is first put into the pre-cleaning box 2 through the feeding platform 12 on the top plate 11. At this time, the diversion mechanism 3 and the crushing mechanism 4 are started synchronously, and the driver 31 in the diversion mechanism drives the diversion turntable 32 to rotate inside the pre-cleaning box 2. The rotation of the diversion turntable 32 can divert the water inside the pre-cleaning box 2, so that the water inside the pre-cleaning box 2 rotates regularly, which has a dispersing effect on the input quartz sand raw material, avoiding local accumulation of the raw material in the pre-cleaning box 2. Through the rotation of the water body, large particles of quartz sand sink and small particles of quartz sand are dispersed to the outside with the water flow. At the same time, it can cooperate with the water in the pre-cleaning box 2 to preliminarily flush the dust and light impurities attached to the surface of the quartz sand.

[0033] The driver 2 41 in the crushing mechanism 4 drives the crushing cone 42 to rotate in the pre-cleaning box 2, and a gradual crushing gap is formed between the crushing cone 42 and the inner wall of the pre-cleaning box 2. As the crushing cone 42 rotates, the large-particle quartz sand after dispersion is squeezed, ground and crushed, and the large-particle quartz sand is processed to a uniform particle size that meets the subsequent processing requirements. In this process, pre-cleaning and crushing are carried out simultaneously, which not only reduces the wear on the crushing components during separate crushing, but also allows the water environment to cool down the heat generated during crushing in time, and also improves the particle size uniformity of the quartz sand.

[0034] After pre-cleaning and crushing, the quartz sand material is transported to the lower cleaning box 7 through the feeding mechanism 6 arranged between the lower cleaning box 7 and the pre-cleaning box 2. The material entering the lower cleaning box 7 will undergo further deep cleaning to remove residual fine impurities; at the same time, the screw conveyor 8 provided on the inner side of the lower cleaning box 7 is started. During the process of conveying the material, the screw conveyor 8 can fully contact the material with water through the stirring action of the spiral blades 821, further enhancing the cleaning effect. Finally, the quartz sand material that has been deeply cleaned and meets the purity requirements will be sent out of the lower cleaning box 7 under the continuous conveyance of the screw conveyor 8, completing the entire quartz sand washing and crushing process.

[0035] Combined with attachment Figure 4 , Attachment Figure 5 and attached Figure 8 As shown, the driver 31 includes a bevel gear 311 driven by a motor and a reduction gear, a gear ring 321 meshing with the bevel gear 311 is provided on the top of the guide turntable 32, a diverter plate 322 is provided in the middle section of the guide turntable 32, and an outflow window 323 and an inflow window 325 are respectively provided on the guide turntable 32 on both sides of the diverter plate 322, and a guide plate 1 324 and a guide plate 2 326 in opposite directions are respectively provided on the outflow window 323 and the inflow window 325, and a liquid pusher plate 328 is provided on the inner side of the bottom of the guide turntable 32.

[0036] During the simultaneous pre-cleaning and crushing of quartz sand, if the raw materials only rely on natural falling to enter the pre-cleaning box 2, local accumulation is likely to occur, resulting in uneven force on the crushing mechanism 4 and reduced crushing efficiency. Quartz sand of different particle sizes cannot be distinguished, resulting in reduced efficiency of the crushing link. At the same time, the cleaning medium flows slowly and is difficult to fully contact with the quartz sand, and surface impurities cannot be efficiently removed. The guide turntable 32 can effectively solve the problems of material accumulation and insufficient contact of the cleaning medium through a specific transmission structure and guide design, thereby ensuring the coordinated and efficient implementation of the pre-cleaning and crushing links.

[0037] When the driver 1 31 is started, the power output by its motor is transmitted to the bevel gear 1 311 after the speed is adjusted by the reduction gear box. Since the gear ring 1 321 on the top of the guide turntable 32 is engaged with the bevel gear 1 311, the rotation of the bevel gear 1 311 will drive the gear ring 1 321 and the entire guide turntable 32 to rotate stably inside the pre-cleaning tank 2; as the guide turntable 32 continues to rotate, the liquid pushing plate 328 provided on the inner side of the bottom of the guide turntable 32 will push the water in the pre-cleaning tank 2 to form a circulation flow when the guide turntable 32 rotates. At the same time, the guide plate 1 324 and the guide plate 2 326 on the outflow window 323 and the inflow window 325 will further circulate the water during the rotation process. Radial diversion, the second guide plate 326 on the inner flow window 325 will make the water flow from the outside of the guide turntable 32 through the inner flow window 325 to the inside, and the guide plate 1 324 and the guide plate 2 326 are set in opposite directions, so that the guide plate 1 324 on the outer flow window 323 drives the water to flow from the inside of the guide turntable 32 through the outer flow window 323 to the outside. During this circulation process, the diverter plate 322 is used to prevent the radial water flows in opposite directions from affecting each other. After diversion, small particles of quartz sand will flow with the water, and the flowing water can more fully contact the evenly distributed quartz sand, thereby achieving even distribution of the quartz sand in the pre-cleaning box 2, and enhancing the flushing effect of dust and light impurities on the surface of the quartz sand.

[0038] Combined with attachment Figure 5 , Attachment Figure 7 and attached Figure 11 As shown, a conical table 21 is provided on the inner side of the bottom of the pre-cleaning box 2, and a crushing cone 42 is rotatably provided on the bottom of the conical table 21. The second driver 41 includes a second bevel gear 411 driven by a motor and a reduction gear box. A second gear ring 425 meshing with the second bevel gear 411 is provided at the bottom of the crushing cone 42. A grinding ring 24 is provided on the outer side of the bottom of the conical table 21. A conveying trough 421 is provided on the outer side of the inclined surface of the crushing cone 42. A crushing trough 422 connected to the conveying trough 421 is provided on the outer side of the bottom of the crushing cone 42. An arc-shaped grinding table 423 cooperating with the grinding ring 24 is provided on the crushing trough 422.

[0039] In the crushing process after the quartz sand is pre-cleaned, if only relying on the conventional crushing structure, it is easy for large pieces of quartz sand to be incompletely crushed and the particle size of the crushed material to be uneven. In addition, when crushed in a water environment, the quartz sand is easy to adhere to the cavity wall, and the material is easy to accumulate below the crushing area, resulting in obstruction of transportation and affecting the crushing process. The crushing cone 42 can effectively solve the problems of incomplete crushing and poor material transportation through the coordinated design with the conical table 21 and its own special trough structure, thereby ensuring the high efficiency and high quality of the quartz sand crushing process.

[0040] When the driver 2 41 is started, the power output by its motor is adjusted to the appropriate crushing speed by the reduction gear box and then transmitted to the bevel gear 2 411. Since the gear ring 2 425 at the bottom of the crushing cone 42 is engaged with the bevel gear 2 411, the rotation of the bevel gear 2 411 will drive the gear ring 2 425 and the entire crushing cone 42 to rotate stably at the bottom of the conical table 21; the large-particle quartz sand that has previously fallen freely through the feeding table 12 falls to the inclined surface area of ​​the crushing cone 42. The conveying trough 421 is provided on the outer side of the inclined surface of the crushing cone 42. During the rotation of the crushing cone 42, the falling quartz sand can be gradually conveyed to the bottom of the crushing cone 42 through the guiding effect of the trough body, thereby avoiding the accumulation of materials on the inclined surface and ensuring that the crushing process is carried out continuously and stably.

[0041] The quartz sand is then crushed into smaller particles by the grinding ring 24 on the outer side of the bottom of the crushing cone 42. The grinding ring 24 on the outer side of the bottom of the crushing cone 42 cooperates with the arc-shaped grinding table 423 on the crushing groove 422 to form a targeted extrusion and shear force on the quartz sand, crushing the large pieces of quartz sand into smaller particles. When the crushing cone 42 rotates, the grinding gap formed between the outer ring of the bottom of the crushing cone 42 and the grinding ring 24 can further grind and refine the quartz sand after the initial crushing, not only making the material particle size more uniform, but also removing the hard impurities attached to the surface of the quartz sand through the grinding action, thereby improving the purity of the quartz sand. In the whole process, the conveying function of the conveying trough 421, the crushing function of the arc-shaped grinding table 423 and the grinding ring 24, and the grinding function of the outer ring of the crushing cone 42 and the grinding ring 24 work together, which not only solves the connection problem between material conveying and crushing, but also realizes the integrated processing of crushing and grinding, providing a material basis with uniform particle size and low impurity content for the subsequent deep cleaning of the lower cleaning box 7.

[0042] Combined with attachment Figure 9 , Attachment Figure 10 and attached Figure 12 As shown, a liquid delivery mechanism 5 is provided at the bottom of the pre-cleaning tank 2, and the liquid delivery mechanism 5 includes a water pump 51 and a liquid separation platform 54. The input end and the output end of the water pump 51 are respectively provided with a liquid inlet pipe 52 and a liquid outlet pipe 53. The liquid inlet pipe 52 extends into the lower cleaning tank 7, and the end of the liquid outlet pipe 53 extends into the liquid separation platform 54 and is rotatably connected to the liquid separation platform 54. A plurality of liquid separation pipes 55 are provided on the liquid separation platform 54, and a high-pressure nozzle 56 is provided at the end of the liquid separation pipe 55. A mounting groove 424 for placing the high-pressure nozzle 56 is provided on the crushing tank 422, and a waste liquid outlet is provided on the pre-cleaning tank 2.

[0043] Combined with attachment Figure 5 and attached Figure 10 As shown, a mesh cage 13 connected to the top of the conical platform 21 is provided at the bottom of the feeding platform 12, and a spiral platform 43 extending into the mesh cage 13 is provided at the top of the crushing cone 42.

[0044] In the pre-cleaning and crushing process of quartz sand, if water is only injected naturally, the crushed material may easily accumulate at the bottom of the crushing cone 42. At the same time, the raw materials may carry large foreign matter into the crushing system during feeding, affecting the life of the crushing components. In addition, the waste liquid containing impurities after cleaning cannot be discharged in time, causing secondary pollution. The liquid feeding mechanism 5 uses a water circulation design and a precise injection structure, in conjunction with the mesh cage 13 at the bottom of the feeding table 12 and the spiral table 43 at the top of the crushing cone 42, to effectively solve the problems of water waste, inaccurate cleaning, interference from raw material impurities and waste liquid accumulation, thereby ensuring the efficiency and environmental protection of the pre-cleaning process.

[0045] When the liquid feeding mechanism 5 is started, the water pump 51 starts working first, and its input end extends into the lower cleaning box 7 through the liquid inlet pipe 52, and extracts the water in the lower cleaning box 7 that has participated in the preliminary cleaning and still has a certain cleaning ability, so as to realize the recycling of water and avoid the waste of water resources; the output end of the water pump 51 pressurizes the extracted liquid through the liquid outlet pipe 53 and delivers it to the liquid separation table 54. Since the end of the liquid outlet pipe 53 is rotatably connected to the liquid separation table 54, during the rotation of the crushing cone 42, the liquid separation table 54 can be synchronously adapted to rotate with the crushing cone 42 to ensure that the subsequent injection direction always corresponds to the crushing area; a plurality of liquid separation pipes 55 are provided on the liquid separation table 54. After pressurization, The liquid is diverted to each diverter pipe 55 through the diverter table 54, and then forms a high-pressure jet stream through the high-pressure nozzle 56 at the end of the diverter pipe 55. The high-pressure nozzle 56 is placed in the mounting groove 424 of the crushing groove 422, so that the high-pressure jet stream directly acts on the quartz sand in the crushing groove 422. On the one hand, the dust generated by the quartz sand during the crushing process and the impurities attached to the surface are quickly removed through high-pressure flushing. On the other hand, the quartz sand can be pushed to the arc-shaped grinding table 423 and the grinding ring 24 for crushing, thereby avoiding the accumulation of quartz sand in the crushing groove 422. Moreover, it can help reduce the temperature of the crushing components caused by friction, thereby extending the service life of the crushing cone 42.

[0046] The mesh cage 13 at the bottom of the feeding platform 12 is connected to the top of the cone-shaped platform 21. When the quartz sand is put into the feeding platform 12, it will first pass through the mesh cage 13. The top of the crushing cone 42 extends into the spiral platform 43 of the mesh cage 13. When the crushing cone 42 rotates, it will rotate synchronously. The spiral structure allows the water added by the liquid feeding mechanism 5 to be transported from the bottom of the crushing cone 42 to the mesh cage 13, and the water in the mesh cage 13 is in a rotating state. At the same time, this water flow will slow down the falling speed of the falling quartz sand and drive the quartz sand to rotate with the water flow. During the rotation, the centrifugal force is used to move the quartz sand. force, the large particles of quartz sand in the raw materials are screened through the mesh cage 13, so that the small particles of quartz sand will enter the pre-cleaning box 2 outside the mesh cage 13, and the large particles of quartz sand will gradually fall into the crushing system below; because the water delivered by the liquid delivery mechanism 5 can flow to the mesh cage 13, an upward water flow is generated, which can drive the crushed quartz sand to rise from the crushing trough 422 position to the mesh cage 13 position with the water flow, and the outward-flowing rotating water flow at the mesh cage 13 will send the small particles of quartz sand to the outside of the mesh cage 13, thereby realizing the transportation of small particles of quartz sand.

[0047] The external water source is directly replenished into the lower cleaning tank 7, and the water in the lower cleaning tank 7 that still has a certain cleaning ability is replenished into the pre-cleaning tank 2 through the liquid delivery mechanism 5. As the pre-cleaning process progresses, the cleaning ability of the water in the pre-cleaning tank 2 decreases (the content of mud, dust and impurities increases), and part of the waste water is regularly discharged through the waste liquid outlet on the pre-cleaning tank 2. The water level in the pre-cleaning tank 2 has a certain floating space to ensure the continuous cleaning and regular reduction of the impurity content in the pre-cleaning tank 2. In the whole process, through the secondary use of water, precise injection, raw material filtration and transportation and the synergistic effect of waste liquid discharge, the pre-cleaning effect and resource utilization are improved, and the stable operation of the crushing link is guaranteed.

[0048] Combined with attachment Figure 5 , Attachment Figure 7 , Attachment Figure 8 , Attachment Figure 13 and attached Figure 14 As shown, a plurality of pushing platforms 327 are evenly provided at the bottom of the guide turntable 32, and the pushing platforms 327 rotate at the bottom of the pre-cleaning box 2. A plurality of discharge ports 22 are provided at the bottom of the pre-cleaning box 2, and a discharge guard plate 23 is provided below the discharge port 22. The lower cleaning box 7 is provided with a feed trough platform 71 at the corresponding position of the discharge port 22, and the feeding mechanism 6 includes a cylinder 61 and a lifting frame 62. A plurality of material protection trough platforms 63 are provided on the lifting frame 62. The material protection trough platform 63 is slidably matched with the discharge guard plate 23 and the feed trough platform 71, and a blocking plate 64 is provided on the inner side of the material protection trough platform 63 for plugging with the discharge port 22.

[0049] Combined with attachment Figure 14As shown, an annular groove 72 is provided on the inner side of the top of the lower cleaning box 7, and an annular pipe 73 is provided in the annular groove 72. The annular pipe 73 is connected to the external water source conveying equipment, and a plurality of nozzles 74 are provided on the annular pipe 73.

[0050] After the quartz sand is pre-cleaned and crushed, it needs to be transported from the pre-cleaning box 2 to the lower cleaning box 7 for deep cleaning. During this process, it is easy for materials to accumulate at the bottom of the pre-cleaning box 2 and be difficult to discharge, materials to spill during transportation, causing waste and pollution, and poor feed connection between the pre-cleaning box 2 and the lower cleaning box 7, resulting in low conveying efficiency. When the lower cleaning box 7 receives the material, it is unable to perform preliminary flushing in time, affecting the deep cleaning effect. The feeding mechanism 6, through the lifting material protection and blocking structure, cooperates with the pushing effect of the guide turntable 32 and the annular pipe spray design of the lower cleaning box 7, can effectively solve the problems of material accumulation, leakage, poor connection and untimely feeding and cleaning, thereby ensuring efficient and clean material transportation and the smooth implementation of subsequent deep cleaning.

[0051] When the quartz sand in the pre-cleaning box 2 is pre-cleaned and crushed, the multiple pushing platforms 327 evenly arranged at the bottom of the guide turntable 32 will rotate synchronously with the guide turntable 32 at the bottom of the pre-cleaning box 2. During the rotation of the pushing platforms 327, the materials accumulated at the bottom of the pre-cleaning box 2 can be pushed, and the materials are gradually pushed to the multiple discharge ports 22 provided at the bottom of the pre-cleaning box 2 to avoid long-term accumulation of materials and blocking the discharge channel; at this time, the feeding mechanism 6 is started, and the cylinder 61 starts to work as a power source, driving the lifting frame 62 to drive the multiple material guarding trough platforms 63 provided thereon to perform lifting and adjustment. Since the material guarding trough platform 63 slides with the discharge guard plate 23 and the feed trough platform 71, the lifting and lowering When the frame 62 descends, the material guarding trough platform 63 will be precisely docked under the discharge guard plate 23 and above the feed trough platform 71 to form a closed material conveying channel. At the same time, the blocking plate 64 provided on the inner side of the material guarding trough platform 63 will be disengaged from the discharge port 22, so that the discharge port 22 is opened. The material in the pre-cleaning box 2 falls into the material guarding trough platform 63 through the discharge port 22 under the continuous push of the pushing platform 327, and then is smoothly conveyed to the lower cleaning box 7 through the feed trough platform 71 along the guiding action of the material guarding trough platform 63. During the entire conveying process, the sliding cooperation between the material guarding trough platform 63, the discharge guard plate 23 and the feed trough platform 71 effectively prevents the material from spilling, thereby solving the problem of material leakage during the conveying process.

[0052] When the material is transported to the lower cleaning box 7, the ring pipe 73 provided in the inner ring groove 72 at the top of the lower cleaning box 7 starts to work, and the ring pipe 73 is connected to the external water source conveying equipment. After the external water source is diverted through the ring pipe 73, clean water is sprayed to the material falling into the lower cleaning box 7 through the multiple nozzles 74 provided on the ring pipe 73, and the material is preliminarily rinsed to prevent the material from adhering to the inner wall of the lower cleaning box 7 and replenishing water for the lower cleaning box 7; when the material transportation is completed, the cylinder 61 drives the lifting frame 62 to rise, driving the material protection trough platform 63 to reset, and the blocking plate 64 is re-engaged with the discharge port 22 to close the discharge port 22 to prevent subsequent material in the pre-cleaning box 2 from leaking in advance; the feeding mechanism 6 realizes efficient and clean transportation of materials between the pre-cleaning box 2 and the lower cleaning box 7 through such a work process, and at the same time cooperates with the ring pipe spraying structure of the lower cleaning box 7 to further improve the cleaning effect of quartz sand.

[0053] Combined with attachment Figure 3 and attached Figure 15 As shown, the screw conveyor 8 includes a motor 81 and two drive shafts 82. The output end of the motor 81 is provided with a pulley 1 811, and one end of the drive shaft 82 is provided with a pulley 2 822. The two pulleys 2 822 are connected by belt transmission, and one of the pulleys 2 822 is connected to the pulley 1 811 by belt transmission. The two drive shafts 82 rotate in the lower cleaning box 7. The drive shafts 82 are each provided with a spiral blade 821. The lower cleaning box 7 is provided with an inclined platform 75. The two drive shafts 82 are tilted on the inclined platform 75, and a vibrating discharge plate 76 is hinged at the end of the inclined platform 75.

[0054] After the quartz sand has been deeply cleaned in the lower cleaning box 7, the clean material needs to be transported out of the equipment. The screw conveyor 8 uses a dual drive shaft linkage transmission, an inclined installation and a spiral blade design, combined with a vibrating discharge plate at the end of the inclined platform to ensure efficient and thorough transportation of the cleaned quartz sand.

[0055] When the screw conveyor 8 is started, the motor 81 starts working as a power source, and the pulley 1 811 provided at its output end rotates accordingly. Since the pulley 2 822 at the end of one of the drive shafts 82 is connected to the pulley 1 811 via a belt transmission, the rotation of the pulley 1 811 drives the pulley 2 822 and the corresponding drive shaft 82 to rotate. At the same time, the pulleys 822 at the ends of the two drive shafts 82 are connected via a belt transmission, so that the other drive shaft 82 also rotates synchronously, realizing the linked operation of the dual drive shafts 82. When the dual drive shafts 82 rotate in the lower cleaning box 7, the spiral blades 821 provided on the shafts rotate synchronously. At the same time, the rotation of the spiral blades 821 can fully stir the material at the bottom of the lower cleaning box 7, achieving a secondary cleaning effect.

[0056] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above and, without departing from the purpose of the present invention, designs structures and embodiments similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
