Description

Technical Field

[0001] This utility model relates to the technical field of antimony mining equipment, specifically a high-pressure water jet-assisted antimony ore scrubbing device. Background Technology

[0002] Antimony ore is an ore with antimony as its main component, possessing significant industrial value. Its core mineral is stibnite, with an antimony content reaching up to 71.4%. As a silvery-white metal, antimony ore is brittle and corrosion-resistant, widely used in flame retardants, battery alloys, semiconductors, and military product manufacturing, especially in flame retardants where its application accounts for up to 60%. During antimony mining, large chunks of ore are first crushed into smaller pieces by a jaw crusher, then washed to remove surface impurities, and finally ground into powder. After preliminary enrichment through gravity separation or flotation, metallic antimony is extracted through pyrometallurgical or hydrometallurgical processes. The washing of small ore chunks is particularly important in this process, requiring antimony ore washing equipment. Existing antimony ore washing equipment typically consists of a shell, a spiral shaft, spiral blades, agitator blades, and a nozzle. The spiral shaft rotates symmetrically inside the shell, the spiral blades are located on the rear side of the spiral shaft's outer surface, the agitator blades are located on the front side of the spiral shaft's outer surface, and the nozzle is located at the top of the shell. Two spiral shafts rotate relative to each other, driving the spiral blades and stirring blades to rotate. Antimony ore and water are simultaneously fed into the front of the shell. The stirring blades continuously agitate the antimony ore, separating it from impurities attached to its surface. Impurities with a lower specific gravity overflow the shell with the water flow, while impurities with a higher specific gravity sink into the sludge collection tank inside the shell. The cleaned antimony ore is then carried upward by the rotating spiral blades until it is carried out of the shell. During the upward movement of the antimony ore, the nozzles at the top of the shell continuously spray high-pressure water jets, creating a secondary rinsing effect on the surface of the antimony ore. In traditional antimony ore scrubbing devices, the nozzles are located at the top of the shell, which can only rinsing the surface layer of antimony ore inside the shell. Furthermore, the nozzles are fixed and the rinsing range is limited, resulting in poor cleaning of the antimony ore surface. Therefore, we propose a high-pressure water jet-assisted antimony ore scrubbing device. Utility Model Content

The input end of the motor is electrically connected to the output end of the microcontroller, and the front end of the output shaft of the motor is fixedly connected to the rear end of the rotating shaft to provide stable drive for the left and right swing of the nozzle.

[0009] Furthermore, the lower spray mechanism includes a mounting block, a mounting groove, a movable head, baffles, and springs. The mounting block is located in the middle of the lower end of the inner side of the scrubbing shell. The upper end of the mounting block has evenly distributed mounting grooves. The movable heads are all slidably connected to the inside of the mounting grooves. The upper ends of the movable heads and the upper ends of the mounting blocks are located on the same horizontal plane. The baffles are all located at the lower end of the movable heads. Springs are provided between the upper ends of the baffles and the top wall of the mounting groove. The springs are all sleeved on the middle of the outer surface of the movable heads, providing a basis for the washing of the antimony ore below.

[0010] Furthermore, the lower spray mechanism also includes a guide groove and a filter screen. A connection hole is provided in the middle of the interior of the movable head. The guide grooves are evenly opened on the upper part of the outer surface of the movable head. All four guide grooves are connected to the vertically adjacent connection holes. The top wall of the guide groove is chamfered. The filter screens are all set on the outer end of the guide groove to avoid impurities clogging the spray port.

[0011] Furthermore, the lower spray mechanism also includes a sealing ring and a sealing ring. The sealing ring is fixedly sleeved on the upper end of the outer surface of the movable head, and the outer edge of the sealing ring is slidably connected to the upper end of the inner wall of the vertically adjacent mounting groove. The sealing ring is set at the outer edge of the baffle, and the outer edge of the sealing ring is slidably connected to the lower end of the inner wall of the vertically adjacent mounting groove, further preventing impurities from clogging the spray nozzle.

[0012] Furthermore, it also includes a spiral shaft, spiral blades, stirring paddles, a gearbox, and a second motor. The spiral shaft is rotatably connected to the left and right sides inside the scrubbing shell. The spiral blades are all located on the rear side of the outer surface of the spiral shaft, with the left and right spiral blades fitted together. The stirring paddles are evenly arranged on the front side of the outer surface of the spiral shaft. The gearboxes are located on the left and right sides of the rear end of the scrubbing shell. The second motor is located on the rear side of the gearbox. The input end of the second motor is electrically connected to the output end of the microcontroller. The front side of the output shaft of the second motor is fixedly connected to the rear side of the reduction shaft of the longitudinally adjacent gearbox. The front end of the output shaft of the gearbox is fixedly connected to the rear end of the longitudinally adjacent spiral shaft, providing a foundation for the scrubbing and conveying of antimony ore.

[0013] Furthermore, it also includes a sludge collection box, which is located at the lower front of the scrubbing shell.

[0014] Furthermore, it also includes a microcontroller, which is located in the middle of the right side of the support frame. The input terminal of the microcontroller is electrically connected to an external power supply to provide control for the cleaning of antimony ore.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-pressure water jet-assisted antimony ore scrubbing device has the following advantages:

[0016] 1. The nozzle swings left and right through the meshing of gear one, gear two, and rack plates. When gear one rotates clockwise, the rack plates on both sides move to the right simultaneously, and the nozzle rotates to the left around the axis of gear two. When gear one rotates counterclockwise, the rack plates on both sides move to the left simultaneously, and the nozzle rotates to the right around the axis of gear two, thus achieving the left and right swing of the nozzle and enabling a wider range of washing effect on the antimony ore.

[0017] 2. The movable head moves up and down by impacting the baffle plate with high-pressure water and the elastic deformation of the spring, thereby extending and retracting the spray nozzle. When the movable head moves up and the spray nozzle extends, the high-pressure water is sprayed out at a 45-degree angle, which washes the antimony ore at the lower end, that is, the antimony ore located at the lower end inside the scrubbing shell. After the high-pressure water supply stops, the baffle plate is no longer under force, and the spring rebounds and retracts the movable head. The upper end of the movable head and the upper end of the mounting block form a plane. With the blocking of the filter screen, sealing ring and sealing ring, impurities will not enter the interior of the mounting block and will not clog the spray nozzle. It can simultaneously achieve a high-pressure washing effect on the antimony ore above and below, thereby improving the cleaning efficiency and cleaning effect of the antimony ore.

The mounting block 41 is located in the lower center of the scrubbing housing 2. The mounting block 41 is connected to an external booster pump via a water pipe. All nozzles 35 are connected to the external booster pump via flexible hoses. The upper center of the mounting block 41 has evenly distributed mounting grooves 42.

The upper ends of the movable heads 43 and the upper ends of the mounting blocks 41 are on the same horizontal plane. The baffles 44 are located at the lower end of the movable heads 43. Springs 45 are provided between the upper end of plate 44 and the top wall of mounting groove 42. Springs 45 are all sleeved on the middle of the outer surface of movable head 43, providing a foundation for washing the antimony ore below. The lower spray mechanism 4 also includes guide grooves 46 and filter screens 47. A connecting hole is provided in the middle of the interior of movable head 43. Guide grooves 46 are evenly distributed on the upper part of the outer surface of movable head 43, and all four guide grooves 46 are connected to vertically adjacent connecting holes. The top wall of the guide grooves 46 is chamfered, allowing high-pressure water to spray out at a 45-degree angle. Filter screens 47 are all located at the outer ends of the guide grooves 46, preventing impurities from entering the interior of the guide grooves 46. The guide grooves 46 on the same movable head 43 are all arranged in a cross shape. The connecting holes are connected to the lower end of the guide grooves 46. The protrusions on the same movable head 43 and the guide grooves 46 are all arranged in a ring-shaped staggered distribution to avoid impurities clogging the injection port. The lower injection mechanism 4 also includes a sealing ring 48 and a sealing ring 49. The sealing ring 48 is fixedly sleeved on the upper end of the outer surface of the movable head 43. The outer edge of the sealing ring 48 is slidably connected to the upper end of the inner wall of the vertically adjacent mounting groove 42. When the movable head 43 moves upward, the sealing ring 48 will push the impurities between the movable head 43 and the mounting groove 42 out of the mounting block 41. The sealing rings 49 are all set at the baffle. At the outer edge of the plate 44, the outer edge of the sealing ring 49 is slidably connected to the lower end of the inner wall of the vertically adjacent mounting groove 42. Both the sealing ring 48 and the sealing ring 49 are made of rubber. The sealing ring 48 and the sealing ring 49 can further reduce the gap between the movable head 43 and the mounting groove 42, and further prevent impurities from clogging the spray nozzle. A spraying mechanism is provided, which is divided into upper and lower parts. It can simultaneously form a high-pressure washing effect on the antimony ore above and below. The upper part can swing left and right, which increases the washing range of antimony ore. The lower part can avoid impurities from clogging the spray nozzle by moving the movable head 43, thereby improving the cleaning efficiency and cleaning effect of antimony ore.

[0030] The working principle of the high-pressure water jet-assisted antimony ore scrubbing device provided by this utility model is as follows: When scrubbing antimony ore, the antimony ore is transported to the front of the scrubbing shell 2 via an external conveyor belt. At the same time, water is pumped into the scrubbing shell 2. The microcontroller 11 controls the operation of the motor 9. The motor 9 drives the spiral shaft 5 to rotate through the reduction gearbox 8. The left spiral shaft 5 rotates clockwise, and the right spiral shaft 5 rotates counterclockwise. The spiral blades 6 and the stirring blades 7 also rotate synchronously. The stirring blades 7 continuously agitate the water and antimony ore. Under the action of the water in the stirring blades 7, the impurities attached to the surface of the antimony ore fall off. The heavier impurities pass through the filter screen and enter the sludge collection box 10 by their own gravity, while the lighter impurities are carried by the water flow out from the overflow port at the upper front of the scrubbing shell 2. As the water flows out, the antimony ore is carried by two rotating spiral blades 6 towards the rear end of the scrubbing shell 2. At this time, the external booster pump works, pressurizing the water and pumping it into the nozzle 35 and the mounting block 41 respectively (the outlet of the external booster pump is connected to the nozzle 35 through a hose). Simultaneously, the microcontroller 11 controls the motor 36 to operate. The output shaft of the motor 36 drives the rotating shaft to rotate. When the rotating shaft rotates forward, the gear 32 also rotates synchronously. Since both gear 32 and gear 33 are meshed with the vertically adjacent rack plate 34, the rack plates 34 on both sides move to the right at the same time, driving the gear 33 to rotate. The nozzle 35 rotates to the left around the axis of gear 33. When the rotating shaft rotates in reverse, gear 32 also rotates synchronously, and the rack plates 34 on both sides move to the right at the same time. When the nozzle moves to the left, it drives gear 33 to rotate, and nozzle 35 rotates to the right around the axis of gear 33. This cycle repeats, allowing nozzle 35 to swing left and right, thus achieving a wider washing effect on the antimony ore. Simultaneously, when high-pressure water enters the mounting block 41, the internal pressure increases. The high-pressure water impacts the lower end of baffle 44, causing baffle 44 to move upwards. The movable head 43 also moves upwards accordingly. At this time, sealing ring 48 and sealing ring 49 move upwards synchronously. Sealing ring 48 initially prevents impurities from entering the equipment and pushes impurities between movable head 43 and mounting groove 42 out of mounting block 41. Sealing ring 49 further prevents impurities from entering the equipment. As movable head 43 moves upwards, spring 45 is compressed until the spring... When the pressure reaches its compression limit, the upper end of the movable head 43 extends beyond the mounting block 41, and the guide channel 46 also extends beyond the mounting block 41, forming a spray nozzle. The filter screen 47 prevents impurities from entering the guide channel 46. High-pressure water passes through the connecting hole in the middle of the movable head 43, through the guide channel 46, and then sprays out at a 45-degree angle along the chamfer at the top wall of the guide channel 46, creating a rinsing effect on the antimony ore at the lower end, i.e., the antimony ore located at the lower end inside the scrubbing shell 2. When the rinsing operation stops, the high-pressure water stops pumping in, the pressure inside the mounting block 41 decreases, the lower end of the baffle 44 is no longer under force, the spring 45 rebounds, driving the movable head 43 back to its original position. The movable head 43 retracts into the mounting block 41, and the guide channel 46 also enters the interior of the mounting block 41 at the same time.The upper end of the movable head 43 and the upper end of the mounting block 41 form a plane. Combined with the blocking effect of the filter screen 47, sealing ring 48, and sealing ring 49, impurities will not enter the interior of the mounting block 41, thus preventing blockage of the spray nozzle.

[0031] It is worth noting that the microcontroller 11 disclosed in the above embodiments is an ATMEGA128A-AUR microcontroller, motor 36 is a Z2D15-24A-13S motor, and motor 9 is a YE3-180M-2 motor. The microcontroller 11 controls the operation of motor 36 and motor 9 using methods commonly used in the prior art.
