AI Technical Summary
Traditional thickener material feeding devices suffer from problems such as low mixing efficiency, uneven settling, and high maintenance costs. In particular, when flocculants are mixed with slurry, local undispersed flocculant clumps are prone to occur. Furthermore, the concentrated fall of slurry in the central area of the thickener leads to an unstable settling layer, and high-viscosity mixtures are prone to adhere to the inner wall of the feeding tank.
It adopts a linkage structure of movable disc, scraper and rotating column, combined with conical diversion disc and differentiated flow guiding structure, and realizes uniform mixing and automatic cleaning of flocculant and slurry by rotating motor drive. After mixing, the residue is removed by scraper, avoiding manual intervention.
This achieves uniform dispersion of flocculants, avoids the accumulation of flocculants in the thickener sedimentation tank, reduces maintenance frequency and costs, and improves production continuity.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of material feeding device technology, and in particular to a material feeding device for a thickener. Background Technology
[0002] Thickeners, as core equipment for solid-liquid separation, are widely used in mining, metallurgy, and environmental protection fields. They accelerate particle sedimentation by mixing flocculants with slurry. Traditional material feeding devices generally suffer from process bottlenecks: First, the mixing of flocculants and materials relies on static pipes or simple stirring, resulting in low mixing efficiency and the formation of localized undispersed flocculant clumps, leading to uneven sedimentation. Second, material feeding often employs a fixed flow guide structure, causing the slurry to concentrate and accumulate in the central area of the thickener, affecting the stable distribution of the sedimentation layer. In addition, high-viscosity mixtures easily adhere to the inner wall of the feeding tank, requiring frequent shutdowns for manual scraping, resulting in high maintenance costs and disruption to continuous production. Therefore, we propose a material feeding device for thickeners. Utility Model Content
[0003] The present invention aims to solve the technical problems existing in the prior art and provide a material feeding device for a thickener.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a material feeding device for a thickener, comprising a feeding tank and a thickener. The feeding tank is a circular barrel with a circular opening at the lower end and is fixedly installed at the center of the thickener. A rotating column is provided at the center of the feeding tank, with one end of the rotating column extending to the bottom of the feeding tank. A connecting cylinder is fixedly installed at the lower end of the feeding tank corresponding to the circular opening at the lower end of the feeding tank. A diverter plate is fixedly installed at the lower end of the rotating column. The diverter plate is conical, and a fixing ring is fixedly installed on the outer side of the diverter plate. A diverter cavity is provided on the side of the diverter plate. A movable disc is movably arranged inside the feeding tank and rotates synchronously with the rotating column. Several connecting blocks are provided on the upper side of the movable disc. A limit block is fixedly installed at the end of the connecting block away from the movable disc. The limit block is a "U"-shaped block, and a scraper is slidably installed inside the limit block. A feed pipe communicating with the interior of the feeding tank is fixedly installed at the upper end of the feeding tank.
[0005] Preferably, a rotary motor is fixedly installed at the upper end of the feeding tank, and the output end of the rotary motor is fixedly connected to the upper end of the rotating column. Two sliding grooves are symmetrically opened on the side of the movable plate, and a slider is fixedly installed on the side of the rotating column corresponding to the position of the sliding groove. The slider is slidably installed inside the sliding groove.
[0006] Preferably, a second rotating cavity is provided on the side of the circular opening at the lower end of the feeding tank, a second rotating ring is rotatably installed inside the second rotating cavity, and connecting rods are fixedly installed at equal intervals on the inner side of the second rotating ring.
[0007] Preferably, the upper end of the movable disc is provided with a first rotating cavity, which is an annular cavity. A first rotating ring is rotatably installed inside the first rotating cavity. A connecting ring is fixedly installed at the upper end of the first rotating ring. A fixing block is fixedly installed on the upper side of the feeding tank. A telescopic device is fixedly installed on the bottom side of the fixing block.

[0011] Beneficial effects
[0012] This utility model provides a material feeding device for a thickener. It has the following beneficial effects:
[0013] (1) The material feeding device for this thickener achieves intelligent switching between mixing and cleaning functions through the linkage structure of the movable disc, scraper, and rotating column. When the rotating motor drives the rotating column to rotate, the movable disc drives the connecting block and scraper to rotate synchronously to form stirring blades, forcibly dispersing the mixed flow of flocculant and slurry; after mixing is completed, the expansion joint pushes the connecting ring upward, and the movable disc drives the limiting block to rise along the slide, forcing the scraper to expand laterally and closely adhere to the inner wall of the feeding tank, automatically scraping away residues during rotation. This design achieves the switching between mixing and cleaning modes through a single drive source, which not only improves the uniformity of flocculant dispersion but also avoids the efficiency loss caused by traditional manual sludge removal.
[0014] (2) The material feeding device for this thickener adopts a conical diverter plate combined with a differentiated flow guiding structure of the first and second water outlets, which significantly improves the uniformity of slurry distribution. When the diverter plate rotates at high speed with the rotating column, the mixed liquid forms a dense vertical downward liquid curtain under the action of centrifugal force through the first water outlet, while the second water outlet guides part of the slurry to be thrown tangentially, expanding the coverage radius. At the same time, the second rotating ring drives the diverter plate to rotate stably through the connecting rod, avoiding the center accumulation caused by the traditional fixed flow guiding structure.

[0024] like Figures 1-4 As shown, a material feeding device for a thickener includes a feeding tank 1 and a thickener. The feeding tank 1 is a circular barrel with a circular opening at the bottom and is fixedly installed at the center of the thickener. A rotating column 2 is arranged at the center of the feeding tank 1, with one end of the rotating column 2 extending to the bottom of the feeding tank 1. A connecting cylinder 3 is fixedly installed at the bottom of the feeding tank 1 corresponding to the circular opening at the bottom of the feeding tank 1. A diverter plate 4 is fixedly installed at the bottom of the rotating column 2. The diverter plate 4 is conical, and a fixing ring 5 is fixedly installed on the outer side of the diverter plate 4. A diverter cavity is opened on the side of the diverter plate 4, and the diverter cavity includes a first water outlet groove 23 equidistantly circumferentially opened on the side of the diverter plate 4. The first outlet trough 23 is a rectangular trough. Two second outlet troughs 24 are symmetrically opened on the side of the diversion plate 4. The second outlet troughs 24 are arc-shaped troughs. The material is evenly sprayed into the sedimentation tank of the thickener through the first outlet trough 23 and the second outlet trough 24. Inside the feeding tank 1, a movable disc 6 is movably installed, rotating synchronously with the rotating column 2. Several connecting blocks 9 are arranged on the upper side of the movable disc 6. A limit block 8 is fixedly installed at the end of the connecting block 9 away from the movable disc 6. The limit block 8 is a "U"-shaped block, and a scraper 7 is slidably installed inside the limit block 8. A feed pipe 25, communicating with the interior of the feeding tank 1, is fixedly installed at the upper end of the feeding tank 1. During use, the material is fed through the feed pipe... 25. Liquid and flocculant are injected into the feed tank 1. The rotating column 2 is rotated, which drives the movable disc 6 to rotate. The movable disc 6 drives the connecting block 9, the limiting block 8, and the scraper 7 to rotate. The rotating connecting block 9 and the scraper 7 act as stirring paddles, ensuring that the flocculant is fully mixed inside the feed tank 1. The movable disc 6 is then driven to move upward, and the material falls onto the distribution disc 4 through the circular opening at the lower end of the feed tank 1. The rotating column 2 drives the distribution disc 4 to rotate, and the mixed flocculant is fully thrown downward through the distribution chamber, allowing the flocculant to fall evenly into the sedimentation tank of the thickener, preventing the flocculant from accumulating in the sedimentation tank of the thickener. The movable disc 6 is then driven to move upward. The movable disc 6 moves upward, driving the connecting block 9 and the limiting block 8 to move upward as well. The limiting block 8, while moving upward, drives the scraper 7 to move laterally, causing the scraper 7 to contact the inner side of the feeding tank 1. The scraper 7 then scrapes and cleans the inner wall of the feeding tank 1 by rotating against it. A groove 13 is provided on the bottom side of the inside of the feeding tank 1, and a sealing ring is fixedly installed on the bottom side of the groove 13. A guide ring 14 is fixedly installed on the bottom side of the movable disc 6 corresponding to the position of the groove 13. When the movable disc 6 and the bottom side of the feeding tank 1 are pressed together, the guide ring 14 extends into the groove 13 to achieve a seal.
[0025] A rotary motor 10 is fixedly installed at the upper end of the feeding tank 1. The output end of the rotary motor 10 is fixedly connected to the upper end of the rotating column 2. Two sliding grooves 11 are symmetrically opened on the side of the movable disk 6. A slider 12 is fixedly installed on the side of the rotating column 2 corresponding to the position of the sliding groove 11. The slider 12 is slidably installed inside the sliding groove 11. The rotary motor 10 drives the rotating column 2 to rotate, and the rotating column 2 drives the movable disk 6 to rotate. A second rotating cavity 20 is opened on the side of the circular opening at the lower end of the feeding tank 1. A second rotating ring 21 is rotatably installed inside the second rotating cavity 20. Connecting rods 22 are fixedly installed at equal intervals on the inner side of the second rotating ring 21. The rotating column 2 carries... The movable connecting rod 22 rotates, and drives the second rotating ring 21 to rotate inside the second rotating cavity 20. The upper end of the movable disk 6 is provided with a first rotating cavity 15, which is an annular cavity. The first rotating ring 16 is rotatably installed inside the first rotating cavity 15. The upper end of the first rotating ring 16 is fixedly installed with a connecting ring 17. The upper side of the feeding tank 1 is fixedly installed with a fixing block 18. The bottom side of the fixing block 18 is fixedly installed with a telescopic device 19. The output end of the telescopic device 19 passes through the feeding tank 1 and is fixedly installed on the upper side of the connecting ring 17. The telescopic device 19 drives the connecting ring 17 to move upward, and the connecting ring 17 drives the movable disk 6 to move upward.
[0026] The working principle of this utility model:
[0027] During use, liquid and flocculant are injected into the feeding tank 1 through the feed pipe 25. Rotating the rotating column 2 causes the movable disc 6 to rotate, which in turn causes the connecting block 9, limiting block 8, and scraper 7 to rotate. The rotating connecting block 9 and scraper 7 act as agitators, ensuring the flocculant is thoroughly mixed inside the feeding tank 1. Then, the movable disc 6 is driven upwards, and the material falls through the circular opening at the bottom of the feeding tank 1 onto the distribution plate 4. The rotating column 2 drives the distribution plate 4 to rotate, and the mixed flocculant is thoroughly thrown downwards through the distribution chamber, allowing it to fall evenly into the thickener's sedimentation tank, preventing accumulation. The movable disc 6 is then driven upwards again, causing the connecting block 9 and limiting block 8 to move upwards. As the limiting block 8 moves upwards, it causes the scraper 7 to move laterally, allowing the scraper 7 to interact with the inner side of the feeding tank 1. The material is first contacted, and then scraped by the scraper 7 against the inner wall of the feeding tank 1 to clean it. The rotary motor 10 drives the rotating column 2 to rotate, which in turn drives the movable disc 6 to rotate. The rotating column 2 drives the connecting rod 22 to rotate, and also drives the second rotating ring 21 to rotate inside the second rotating cavity 20. The telescopic device 19 drives the connecting ring 17 to move upward, and the connecting ring 17 drives the movable disc 6 to move upward. When the movable disc 6 is pressed against the inner bottom side of the feeding tank 1, the guide ring 14 extends into the groove 13 to achieve a seal. The material is evenly sprayed into the sedimentation tank of the thickener through the first water outlet 23 and the second water outlet 24. When the movable disc 6 descends to the initial position, the guide ring 14 is embedded in the groove 13 to form a seal and prevent the leakage of unmixed material. The scraper 7 retracts with the limit block 8 to prepare for the next mixing cycle. The entire process is fully automated through the timing control of the rotary motor 10 and the telescopic device 19.
