Description

Technical Field

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

[0002] Quartz sand is quartz particles obtained by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand is also an important industrial mineral raw material and a non-hazardous chemical. It is widely used in industries such as glass, casting, ceramics, fireproofing, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasives, and filter media.

[0003] Chinese patent application number CN209772916U discloses a rotary cleaning device for quartz sand. Water is poured into a tank, and then quartz sand is fed into a rotating drum through a feed pipe. The drum is then rotated by a motor via a rotating rod, causing the quartz sand to tumble and rub against each other in the drum, which can quickly and efficiently remove impurities on the surface of the quartz sand and expel them out of the drum.

[0004] However, the above-mentioned rotary cleaning equipment for quartz sand still has the following shortcomings when cleaning:

[0047] The material guiding mechanism 6 is arranged outside the sand washing box 2 and is used to receive and guide the quartz sand after being scooped;

[0048] A partition 7 is installed inside the base 1, which divides the inner cavity of the base 1 into a sewage compartment 8 and a drive compartment 9. The sewage return mechanism 4 and the drive part of the sand washing box 2 are both arranged in the drive compartment 9, and the outer wall of the base 1 has a hatch connected to the drive compartment 9;

[0049] The sewage return mechanism 4 includes a pump body 41 and a one-way valve 42. The pump body 41 is installed in the drive cabin 9. The water suction pipe of the pump body 41 is connected to the interior of the sewage tank 8. The drainage pipe of the pump body 41 extends upward to the top of the base 1 and is connected to the bottom of the inner cavity of the sand washing box 2. The one-way valve 42 is installed in the middle of the drainage pipe of the pump body 41 and is located between the base 1 and the sand washing box 2.

[0050] In this embodiment, the sand washing box 2 includes an outer box 21, a sand washing filter liner 22, a rotating column 23 and a driving unit. The outer box 21 is installed on the top of the base 1 through a bracket. The sand washing filter liner 22 is rotatably arranged in the outer box 21. The top of the rotating column 23 is installed in the middle of the bottom end of the sand washing filter liner 22. The bottom end of the rotating column 23 extends to the bottom of the outer box 21 and is rotatably connected to the base 1. The driving unit drives the rotating column 23 to drive the sand washing filter liner 22 to rotate in the outer box 21 to wash sand;

[0051] Specifically, the bracket includes a plurality of support rods. The outer box 21 is cylindrical. The plurality of support rods are symmetrically distributed in a ring shape on the outer edge of the bottom end of the outer box 21. The other ends of the support rods are fixedly connected to the upper surface of the base 1, thereby installing the outer box 21 above the base 1.

[0052] Specifically, the sand washing filter liner 22 is a cylindrical inner liner, and the tops of the outer box 21 and the sand washing filter liner 22 are both open to facilitate the injection of quartz sand and water. In addition, the liner wall of the sand washing filter liner 22 is provided with evenly distributed filter holes for filtering small particles of impurities during centrifugation.

[0053] Specifically, the middle part of the bottom end of the outer box 21 is rotatably connected to the rotating column 23 through a bearing seat, and the connection is sealed and waterproof, which does not affect the rotation of the sand washing filter 22 at the bottom end of the rotating column 23 and can also prevent sewage from dripping;

[0054] Furthermore, a material guide platform 12 is installed at the bottom of the inner cavity of the outer box 21. The upper surface of the material guide platform 12 is an inclined surface, and the bottom end of the inclined surface is a drainage port to facilitate the discharge of sewage and impurities.

[0055] Specifically, a cleaning brush 24 is installed on the inner wall of the outer box 21, and the bristles of the cleaning brush 24 are in contact with the filter holes on the wall of the sand washing filter 22. The driving part drives the rotating column 23 to rotate, so that the sand washing filter 22 rotates in the outer box 21, so that the bristles of the cleaning brush 24 continuously scrub the wall of the sand washing filter 22, which can avoid the filter holes of the sand washing filter 22 from being blocked, thereby improving the sand washing effect and efficiency.

[0056] Furthermore, the driving part includes a motor 10 and a gear set 11. The motor 10 is mounted on the base 1. The gear set 11 includes a main gear and a sub-gear. The main gear is fixedly sleeved on the output shaft of the motor 10, and the sub-gear is fixedly sleeved on the bottom end of the rotating column 23. The main gear and the sub-gear are meshed with each other.

[0057] The motor 10 is installed in the drive cabin 9. The motor 10 drives the main gear to rotate, so that the sub-gear drives the rotating column 23 to rotate synchronously, thereby driving the sand washing filter 22 to rotate, so as to rotate and clean the quartz sand in the sand washing filter 22;

[0058] In this embodiment, the transmission mechanism includes a bevel gear transmission assembly 15, a first belt transmission assembly 16, and a second belt transmission assembly 17. The bevel gear transmission assembly 15 has two mutually perpendicular gear shafts, one of which is transmission-connected to the rotating column 23 through the first belt transmission assembly 16, and the other gear shaft is transmission-connected to the movable end of the sand bailing mechanism 5 through the second belt transmission assembly 17.

[0059] Specifically, the sand bailing mechanism 5 includes a fixed plate 51, one end of which is mounted on the bottom of one side of the base 1, and the other end of the fixed plate 51 extends to the upper side of the outer box 21 and is rotatably connected to a rotating shaft 52. One end of the rotating shaft 52 extends horizontally to the upper side of the sand washing filter 22 and is installed with a plurality of connecting rods 53. The connecting rods 53 are vertically arranged, and a sand bailing bucket 54 is installed at the end of the connecting rod 53 away from the rotating shaft 52. The rotating shaft 52 is connected to the rotating column 23 through a transmission mechanism, and the rotating column 23 drives the rotating shaft 52 and the connecting rod 53 to rotate, so that the rotating shaft 52 drives the sand bailing bucket 54 to rotate and enter the sand washing filter 22 to bailed sand;

[0060] Specifically, the bevel gear transmission assembly 15 includes two mutually perpendicular bevel gears, and a gear shaft is installed in the middle of each bevel gear, one of which is vertically distributed and parallel to the rotating column 23, and the other is horizontally distributed and perpendicular to the rotating column 23;

[0061] Furthermore, the first belt transmission assembly 16 includes two pulleys and a first belt. The two pulleys are respectively mounted on the rotating column 23 and the vertical gear shaft, and the first belt is sleeved on the two pulleys.

[0062] Furthermore, the second belt transmission assembly 17 includes two pulleys and a second belt, wherein the axle of one pulley is located at the bottom and is fixedly connected to one end of the horizontal gear shaft extending to the outside of the base 1, and the axle of the other pulley is rotatably mounted on the upper part of the fixed plate 51. The two pulleys are connected by a second belt transmission, and the end of the rotating shaft 52 away from the outer box 21 is connected to the pulley shaft located at the top through a gear transmission member.

[0063] Furthermore, the gear transmission member includes a first gear 18 and a second gear 19. The first gear 18 is mounted on the end of the rotating shaft 52 away from the outer box 21, and the second gear 19 is mounted on the pulley shaft of the second belt transmission assembly 17 located above. The first gear 18 and the second gear 19 are meshed with each other. Through such transmission, while achieving rotary sand washing, it can also drive the connecting rod 53 and the sand bailing bucket 54 to rotate and enter the sand washing filter 22 to bailed sand, thereby improving work efficiency.

[0064] Furthermore, the second gear 19 is an incomplete gear, and the ratio of the teeth on the outer periphery of the second gear 19 to the total circumference is 1:n, where n is an integer greater than 1. This design allows the second gear 19 to drive the first gear 18 to rotate intermittently, thereby achieving intermittent sand bailing, allowing the sand bailing hopper 54 to remain in the sand washing filter 22 for a period of time to collect the rotating quartz sand. At the same time, since the connecting rod 53 and the sand bailing hopper 54 are in the sand washing filter 22, the stirring and mixing amplitude of the quartz sand can be increased, thereby improving the quartz sand cleaning effect.

[0065] Furthermore, the total length of the connecting rod 53 and the sand bailing hopper 54 is less than the distance between the lower surface of the rotating shaft 52 and the bottom of the inner cavity of the sand washing filter 22, which will not affect the normal sand bailing operation. In addition, the surface of the sand bailing hopper 54 has evenly distributed water filtering holes, and the pore size of the water filtering holes is smaller than the particle size of the quartz sand, so that the quartz sand can be bailed out at the same time as the water is drained.

[0066] In this embodiment, the material guide mechanism 6 includes a material guide plate 64 rotatably arranged on the outer side of the sand washing box 2, and a driving mechanism for driving the material guide plate 64 to flip, and the axis of the rotating shaft of the material guide plate 64 is parallel to the axis of the rotating shaft 52;

[0067] The gear 62 is rotated between the two fixed blocks 61 by a rotating shaft, and one end of the rack 63 is mounted on the upward movable end of the second driving member 65. The other end of the rack 63 extends between the two fixed blocks 61. The flat side of the rack 63 is slidably connected to the adjacent fixed blocks 61. The tooth surface of the rack 63 and the gear 62 are meshed with each other. A support plate is installed on the side of the guide plate 64 close to the fixed block 61. The support plate is fixedly connected to the rotating shaft. The rack 63 is driven to rise and fall by the second driving member 65, thereby driving the gear 62 and the rotating shaft to rotate, and then driving the guide plate 64 to flip, so as to adjust the inclination angle of the guide plate 64, which is convenient for receiving and guiding the quartz sand dumped by the sand scoop 54.

[0068] The second driving member 65 can be a pneumatic cylinder, an oil cylinder or an electric cylinder in the prior art;

[0069] It should be noted that when the top end of the material guiding mechanism 6 is turned over and extended to the top of the sand washing filter 22, it will be between the two connecting rods 53. After the material guiding is completed, the material guiding mechanism 6 is reset. At this time, the rotating shaft 52 drives the connecting rod 53 and the sand scoop 54 to continue rotating. That is, the action of the material guiding mechanism 6 is in the idle period of the rotation of the rotating shaft 52, which will not affect the normal sand scooping and material guiding.

[0070] In this embodiment, the filtering mechanism 3 includes a filter screen 31, a first driving member 32 and a scraper 33. The filter screen 31 is mounted on the cavity opening of the base 1 and is located directly below the drain outlet of the sand washing box 2. The first driving member 32 is mounted on the side of the bottom of the sand washing box 2 away from the drain outlet. The scraper 33 is mounted on the movable end of the first driving member 32 and is slidably connected to the upper surface of the filter screen 31 to push out impurities filtered on the filter screen 31. The first driving member 32 can be a pneumatic cylinder, an oil cylinder or an electric cylinder in the prior art.

[0071] Furthermore, the upper surface of the filter screen 31 is an inclined surface, and the axis of the first driving member 32 is parallel to the inclined surface. The filter screen 31 is used to filter particulate impurities in the sewage above, so that the particulate impurities are retained on the upper surface of the filter screen 31. The first driving member 32 drives the scraper 33 to slide on the upper surface of the filter screen 31, thereby pushing the impurities on the upper surface of the filter screen 31 outward. A waste box 14 can also be provided on the side of the base 1. The top of the waste box 14 is open and located below the inclined surface of the filter mechanism 3 to collect particulate impurities.

[0072] In summary, the quartz sand cleaning device proposed in the present invention drives the rotating column 23 and the sand washing filter 22 to rotate by the motor 10, so that the quartz sand, impurities and water in the sand washing filter 22 are mixed and rotated centrifugally, thereby allowing small particles of impurities to pass through the filter holes of the sand washing filter 22 and be thrown out into the outer box 21, thereby achieving the impurity removal and cleaning of the quartz sand. At the same time, the rotating shaft 52 is driven to rotate by the first belt transmission assembly 16, the bevel gear transmission assembly 15 and the second belt transmission assembly 17, so that the rotating shaft 52 drives the connecting rod 53 and the sand bailing bucket 54 to enter the sand washing filter 22, and the sand bailing bucket 54 is in the sand washing filter 22. The outer edge of the bottom end of the inner cavity can reversely salvage the quartz sand in the rotating centrifugal state. While salvaging the quartz sand, it can also increase the mixing and stirring amplitude, thereby improving the quartz sand cleaning effect; the cleaning sewage in the outer box 21 is discharged downward through the drain port at the bottom, and then the small particles of impurities in the sewage are filtered through the filtering mechanism 3, so that the sewage enters the base 1 after filtration, and then the filtered water is extracted by the pump body 41 and transported upward to the outer box 21, so as to circulate and clean the quartz sand, thereby improving the cleaning effect, and realizing the recycling of sewage, reducing water consumption, and being beneficial to energy saving and environmental protection.

[0073] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
