Description

Technical Field

[0001] The invention relates to the technical field of cleaning of mining flotation machines, in particular to an anti-scaling tail silt removal mechanism of a mining flotation machine. Background Art

[0002] Mining flotation machines play a vital role in the mining and processing of mineral resources. Their operating principle is based on the differences in the physical and chemical properties of mineral surfaces. By adding specific reagents, the target mineral selectively attaches to bubbles and floats upward, thereby separating it from the gangue minerals. Flotation machines are widely used in the separation of non-ferrous metals such as copper, lead, zinc, and gold, as well as some ferrous metals and non-metallic ores.

[0003] During the operation of a mining flotation machine, scaling often occurs at the tail of the flotation machine due to the precipitation and adhesion of minerals in the slurry. This scaling not only affects the normal operation of the flotation machine and reduces flotation efficiency, but may also cause equipment failure and increase maintenance costs. Although existing equipment can clean the tail of the flotation machine through a spray head, the spray head can remove dirt, but it is not convenient to clean the dirt attached to the side wall of the tail of the flotation machine. In addition, the existing spray head is not convenient for adjusting the cleaning diameter of the spray head according to the amount of deposited dirt.

[0004] In response to the above problems, it is urgent to carry out innovative design based on the original foundation. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention, through the provision of a movable frame, a movable platform, a scraper and a spraying platform, can enable the spray head to reciprocate and flush the pre-scraped area when cleaning the inner wall of the tail mechanism of the flotation machine, and then completely clean it through the scraper. The reciprocating flushing spraying method can cover every corner of the inner wall of the tail mechanism of the flotation machine, and preliminarily flush off the impurities, residual minerals, etc. attached to the inner wall. The reciprocating flushing can impact these areas multiple times, expose and flush away the hidden dirt, and the scraper then performs a complete cleaning, which can further scrape off the stubborn stains or tightly adhered impurities that still remain after the spraying, and can completely flush away the remaining fine particles and stains, thereby greatly improving the thoroughness of the cleaning.

[0018] The present invention, through the provided pressure regulating assembly and the spraying station, when the dirt adhering to the inner wall of the tail mechanism of the flotation machine has a strong adsorption force, the dirt exerts pressure on the scraper, and the pressure regulating assembly reduces the reciprocating distance of the spray head, thereby concentrating on flushing the area where the dirt is attached. If all areas are fully flushed with high intensity, it will not only waste water resources, but may also cause unnecessary wear to the inner wall of the tail mechanism of the flotation machine. By only performing high-intensity treatment on the area where the dirt is attached, excessive flushing of other areas is avoided, thereby reducing the impact and wear of the water flow on the inner wall and extending the service life of the equipment.

[0019] The present invention, through the provided caliber adjustment component, can reduce the output caliber of the sprinkler head when the sprinkler head concentrates on flushing the area where dirt is attached. At this time, the water flow will be more concentrated, forming a water column with higher energy. This concentrated water flow can be sprayed more accurately to the area where dirt is attached, avoiding dispersion and waste of water flow. For stubborn dirt attached to the inner wall of the tail mechanism of the flotation machine, such as tightly adhered mineral particles, dirt layers formed by a mixture of oil and minerals, etc., the high-impact water flow can more effectively penetrate the dirt layer, destroy the adhesion between the dirt and the inner wall, and peel off the dirt from the inner wall, thereby significantly improving the cleaning effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figures 1-13 The present invention provides a technical solution: a tail silt removal mechanism for a mining flotation machine with anti-scaling, comprising a mounting platform 1, an electric push rod 2 mounted on the top of the mounting platform 1, a moving frame 3 mounted on the protruding end of the electric push rod 2, a moving frame 4 slidingly limited inside the moving frame 3, an adjusting platform 5 disposed at the bottom of the moving frame 4, a turntable 6 rotatably connected to the top of the moving frame 4, a turntable 7 slidingly limited inside the turntable 6, a gear ring 8 mounted on the surface of the turntable 7, a rack 9 mounted at the bottom of the moving frame 3, a pressure regulating assembly mounted at the bottom of the moving frame 4, a scraper 11 mounted inside the regulating platform 5, a spraying platform 12 slidingly limited inside the groove inside the moving platform 4, a closing block 13 slidingly limited vertically on the spraying platform 12, and a caliber regulating assembly mounted inside the spraying platform 12;

[0036] The pressure regulating assembly includes a gear column 101 installed at the top of the movable platform 4, a slide 102 is provided at the top of the movable platform 4, and the side end of the slide 102 is connected to the spraying platform 12, and also includes a movable rod 103 that slides in the internal slide groove of the turntable 6, and the end of the movable rod 103 is installed with a pressure block 104 through the slide rod. A limiting plate 105 is installed at the bottom end of the round rod at the bottom of the rotating plate 7, and an extrusion platform 106 is installed at the bottom of the limiting plate 105. A groove platform 108 is installed at the bottom end of the movable platform 4. The pressure regulating assembly can reduce the reciprocating distance of the sprinkler head, thereby concentrating on flushing the area with attached dirt, avoiding excessive flushing of other areas, thereby reducing the impact and wear of water on the inner wall, and extending the service life of the equipment.

[0037] As an embodiment of the present invention, the interior of the mobile frame 3 is connected to a screw rod through the rotation of the motor, and the interior of the mobile platform 4 is threadedly connected to the screw rod inside the mobile frame 3. When the motor drives the screw rod to rotate, the mobile platform 4 can slide within the mobile frame 3 within a limited position, thereby driving the scraper 11 to clean the inner wall;

[0038] As an embodiment of the present invention, a motor is installed on the side end of the adjustment platform 5, and the output end of the motor passes through the adjustment platform 5 and is connected to the side end of the scraper 11. The area below the surface of the scraper 11 is provided with an inclined surface, and a plurality of convex strips are installed on the inclined surface. The opening of the inclined surface of the scraper 11 allows the dirt to be retained on the surface of the scraper 11 after cleaning the inner wall, which facilitates the cleaning work of the staff. The establishment of the plurality of convex strips can reduce the loss of dirt.

[0039] As an embodiment of the present invention, a protrusion is installed on the top of the moving table 4, and a slide 102 is limited and slid in the protrusion. A slider is installed in the middle area of ​​the slide 102, and the bottom of the moving rod 103 is limited and slid in the groove inside the slider. A spring is sleeved on the surface of the slide rod at the end of the moving rod 103, and an inclined surface is provided at the end of the pressure block 104. A rounded corner is provided at the bottom of the extrusion table 106. The round rod at the bottom of the rotating plate 7 is located in the inner area of ​​the turntable 6 and is sleeved with a spring. When the turntable 6 rotates, the internal moving rod 103 is limited and slid in the groove inside the slider, thereby driving the slide 102 to limit and slide in the protrusion. By changing the position of the moving rod 103 in the turntable 6, the sliding distance of the slide 102 can be adjusted;

[0040] As an embodiment of the present invention, the adjusting platform 5 is limited and slides inside the groove platform 108. A spring is installed on the side end of the inner wall of the groove platform 108, and the other end of the spring is connected to the adjusting platform 5. The front and rear ends of the adjusting platform 5 are installed with a resistance block 109 through a connecting rod. The vertical limited sliding of the movable platform 4 is provided with a resistance rod 107. The top of the resistance rod 107 is rotatably connected to the bottom of the rotating plate 7. The top of the resistance block 109 is provided with an inclined surface. The bottom of the resistance rod 107 is in conflict with the inclined surface of the resistance block 109. When the scraper 11 is squeezed, the resistance block 109 squeezes the resistance rod 107 to drive the rotating plate 7 to rise.

[0041] As an embodiment of the present invention, the caliber adjustment component includes a first oil tank 141 installed at the top of the turntable 6, a first piston rod 142 is limited and slidably provided inside the first oil tank 141, and the top of the first piston rod 142 is connected to the bottom end of the turn plate 7, and also includes a second oil tank 143 installed in the cavity at the top of the spray station 12, a second piston rod 144 is vertically limited and slidably provided inside the second oil tank 143, a third piston rod 145 is horizontally limited and slidably provided inside the second oil tank 143, an adjustment rod 146 is vertically limited and slidably provided in the cavity of the spray station 12, and an extrusion block 147 is installed at the end of the third piston rod 145. The caliber adjustment component can reduce the output caliber of the spray head when the spray head concentrates on flushing the area where dirt is attached. At this time, the water flow will be more concentrated to form a water column with higher energy. This concentrated water flow can be more accurately sprayed to the area where dirt is attached;

[0042] Although the spray head can clean the dirt, it is not convenient to clean the dirt attached to the side wall of the tail of the flotation machine. In addition, the existing spray head is not convenient to adjust the cleaning diameter of the spray head according to the amount of deposited dirt. The specific implementation method is as follows: first, the controller drives the electric push rod 2 to drive the mobile frame 3 to descend until the scraper 11 contacts the inner wall of the tail of the flotation machine, and then the motor drives the internal screw of the mobile frame 3 to rotate. At this time, the screw rotation drives the mobile platform 4 to move inside the mobile frame 3. At the same time, the external water pipe is connected to the spray platform 12, so that the spray platform 12 is sprayed to the rear of the flotation machine. The scraper 11 is ready to scrape and rinse the area. When the mobile platform 4 moves inside the mobile frame 3, the rack 9 at the bottom of the mobile frame 3 drives the gear column 101 to rotate. The rotation of the gear column 101 drives the rotating plate 7 to rotate through the gear ring 8. When the rotating plate 7 rotates, it drives the turntable 6 to rotate together through the limit plate 105. When the turntable 6 rotates, the internal moving rod 103 slides within the middle slider of the slide 102, thereby driving the slide 102 to slide within the limit at the top of the mobile platform 4. The slide 102 slides horizontally and drives the spray station 12 to move back and forth horizontally inside the mobile platform 4, flushing the scraping area back and forth.

[0043] As one embodiment of the present invention, a spring is sleeved on the surface of the extrusion block 147. The top of the extrusion block 147 has a rounded corner. The bottom of the extrusion block 147 passes through the cavity at the top of the spray station 12 and connects to the top of the closing block 13. The end of the extrusion block 147 has an inclined surface, and the top of the adjustment rod 146 abuts against the inclined surface of the extrusion block 147. The extrusion block 147 abuts against the adjustment rod 146, causing it to move downward, which in turn causes the closing block 13 to move downward, thereby adjusting the diameter of the spray head.

[0044] As an embodiment of the present invention, the second oil tank 143 has a "T" structure, and the third piston rod 145 slides within the oil cavity at the side end of the second oil tank 143. A hose is connected between the first oil tank 141 and the second oil tank 143. The second oil tank 143 with a T" structure can push the third piston rods 145 on both sides to extend when the second piston rod 144 rises.

[0045] Working principle: During cleaning, the controller first drives the electric push rod 2 to drive the moving frame 3 to descend until the scraper 11 contacts the inner wall of the tail of the flotation machine, and then the motor drives the internal screw of the moving frame 3 to rotate. At this time, the rotation of the screw drives the moving platform 4 to move inside the moving frame 3. At the same time, the external water pipe is connected to the spraying platform 12, so that the spraying platform 12 rinses the area to be scraped by the scraper 11. When the moving platform 4 moves inside the moving frame 3, the rack 9 at the bottom of the moving frame 3 drives the gear column 101 to rotate, and the rotation of the gear column 101 drives the turn plate 7 to rotate through the gear ring 8. When the turn plate 7 rotates, it drives the turntable 6 to rotate together through the limit plate 105. When the turntable 6 rotates, the internal moving rod 103 slides within the middle slider of the slide 102, thereby driving the slide 102 to slide within the limit at the top of the moving platform 4. The slide 102 slides horizontally, driving the spraying platform 12 to move back and forth horizontally inside the moving platform 4, and the scraping area is rinsed back and forth.

[0046] When the scraper 11 moves, the dirt attached to the inner wall of the tail mechanism of the flotation machine exerts pressure on the scraper 11, causing the adjusting platform 5 to slide within the limit position inside the groove platform 108. At this time, the adjusting platform 5 drives the resistance block 109 to move. When the resistance block 109 moves, it interferes with the resistance rod 107 to make it rise inside the moving platform 4. The rising resistance rod 107 drives the rotating plate 7 to move upward. When the rotating plate 7 moves upward, it drives the extrusion platform 106 to move upward together through the limit plate 105. The pressure exerted by the extrusion platform 106 on the pressure block 104 becomes smaller, and the spring drives the pressure block 104 to retract into the turntable 6. At this time, the position of the moving rod 103 in the internal slide groove of the turntable 6 changes. The turntable 6 rotates the internal moving rod 103 to slide in the middle slider of the slide 102, and the distance that the slide 102 slides within the limit position at the top of the moving platform 4 becomes smaller. At this time, the slide 102 slides horizontally, driving the spray platform 12 to move back and forth horizontally inside the movable platform 4, and the distance is also reduced synchronously. The resistance rod 107 rises and drives the rotating plate 7 to move upward. At the same time, the rotating plate 7 pulls the first piston rod 142 to rise inside the first oil tank 141. At this time, the oil inside the first oil tank 141 is injected into the second oil tank 143. The oil inside the second oil tank 143 pushes the second oil tank 143 to rise. The oil in the upper layer of the second oil tank 143 is squeezed and gradually injected into the oil cavities on both sides, pushing the third piston rod 145 to extend. The extension of the third piston rod 145 drives the squeezing block 147 to extend together. The squeezing block 147 extends and contacts the adjusting rod 146, causing it to drive the closing block 13 to descend, thereby reducing the output diameter of the spray platform 12 and increasing the spraying force.

[0047] When the scraper 11 gradually moves to the end point, the controller drives the side motor of the adjustment platform 5 and the electric push rod 2 to work synchronously, so that the scraper 11 rotates to a vertical state, and the bottom of the scraper 11 always fits with the inner wall of the tail mechanism of the flotation machine, leaving the cleaned dirt on the surface of the closing block 13.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
