Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically a dust suppressant rapid dissolution device. Background Technology

[0002] Dust suppressants are composed of novel multifunctional high-molecular polymers. The cross-linked molecules in the polymer form a network structure, and there are various ionic groups between the molecules. Due to the high charge density, they generate a strong affinity with ions and can quickly capture and firmly adsorb particulate dust through coagulation and adhesion. After drying, they can solidify into a film on the dust surface, thus having a strong dust suppression and prevention effect. They can be widely used in coal and various metal and non-metal mining areas, mineral slag stockpiles, coal and mineral powder transportation, mineral earthwork storage and unloading sites, building demolition, roads under construction, thermal power plants, cement plants, steel plants, metallurgical plants, dust workshops, artificial beaches and desertified areas, etc.

[0003] Dust suppressants include both solid and liquid dust suppressants. Solid dust suppressants are in powder form and need to be mixed with water in a specific ratio before use. In practice, a suitable amount of water is usually added to the mixing tank first, followed by the addition of the powdered dust suppressant and stirring. During this process, the powdered dust suppressant is prone to clumping when it comes into contact with the water surface, which requires more time to fully dissolve. Therefore, to avoid clumping, a rapid dust suppressant dissolution device is provided. Utility Model Content

[0017] The dispersing toothed discs are distributed below the bottom of the feed hopper and are fixedly connected to the bottom of the conveying shaft. The initially mixed solution falls and comes into contact with the rotating dispersing toothed discs, where it is further dispersed and mixed.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-4 In this embodiment of the present invention, a dust suppressant rapid dissolution device includes a dissolution assembly 1 consisting of a mixing tank 101, a feeding hopper 102, and a discharge valve 103. The feeding hopper 102 is fixed to one side of the top of the mixing tank 101 and extends to the inside of the mixing tank 101. The discharge valve 103 is fixed to the middle of the bottom of the mixing tank 101 and communicates with the inside of the mixing tank 101.

The stirring assembly 2 is used to stir and mix the solution inside the mixing tank 101.

[0034] An anti-caking feeding component 3 is provided inside the feed hopper 102. The anti-caking feeding component 3 includes a conveying unit, a premixing unit, and a linkage unit.

[0035] The conveying unit is used to convey the dust suppressant powder inside the feed hopper 102 downwards, and the premixing unit is used to achieve the initial premixing of water and dust suppressant powder;

[0036] The linkage unit is used to transmit the operating power of the stirring assembly 2 to the conveying unit, providing driving force for the operation of the conveying unit;

[0037] The stirring assembly 2 includes a first support 201, a drive motor 202, a central rotating shaft 203, and an L-shaped stirring rod 204;

[0038] The drive motor 202 is fixedly installed on the top of the mixing tank 101 via the first bracket 201. The central rotating shaft 203 is fixed to the bottom of the output end of the drive motor 202, passes through the first bracket 201, and extends into the interior of the mixing tank 101. The L-shaped stirring rod 204 is distributed on the inner side of the mixing tank 101 and fixed on the outer side of the central rotating shaft 203.

[0039] The drive motor 202 drives the central rotating shaft 203 and the L-shaped stirring rod 204 to rotate, thereby agitating and mixing the solution inside the mixing tank 101.

[0040] The conveying unit includes a second support 301, a conveying shaft 302, and a spiral blade 303;

[0041] The second support 301 is fixed to the top of the mixing tank 101 and distributed on the outside of the feed hopper 102, and extends to the top of the feed hopper 102. The conveying shaft 302 is rotatably connected to the second support 301 and passes through the upper and lower ends of the second support 301. The bottom of the conveying shaft 302 extends through to the bottom of the feed hopper 102.

[0042] Spiral blades 303 are distributed inside the feed hopper 102 and fixed to the outer wall of the conveying shaft 302. When the conveying shaft 302 rotates and drives the spiral blades 303 to rotate, it is used to convey the powder inside the feed hopper 102 downward.

[0043] The premixing unit includes a dispersing toothed disc 304, a water inlet 305, and a water outlet 306;

[0044] The water inlet 305 is opened at the top of the conveying shaft 302 and extends close to the bottom of the conveying shaft 302. The water outlet 306 is circumferentially opened on the outside of the conveying shaft 302 and communicates with the bottom of the water inlet 305. The water outlet 306 is distributed below the spiral blade 303. Water is injected through the channel formed by the water inlet 305 and the water outlet 306. The water flows out through the water outlet 306 and initially contacts and mixes with the powder conveyed downward.

[0045] The dispersing toothed disc 304 is distributed below the bottom of the feed hopper 102 and is fixedly connected to the bottom of the conveying shaft 302. The initially mixed solution falls and comes into contact with the rotating dispersing toothed disc 304 and is then dispersed and mixed a second time.

[0046] The linkage unit includes a driven pulley 307, a driving pulley 308, and a transmission toothed belt 309;

[0047] Driven pulleys 307 are distributed above the second bracket 301 and are fixedly connected to the outside of the conveying shaft 302. Driven pulleys 308 are fixed to the outside of the drive motor 202 and are at the same horizontal height as driven pulleys 307.

[0048] The transmission toothed belt 309 is sleeved on the outside of the driven pulley 307 and the driving pulley 308, and is used to transmit the rotational power of the drive motor 202 to the conveying shaft 302 to realize the rotation of the conveying shaft 302;

[0049] The horizontal height of the outlet 306 is higher than the horizontal height of the bottom of the feed hopper 102, and the outer diameter of the outer teeth of the dispersing toothed disc 304 matches the inner diameter of the bottom of the feed hopper 102.

[0050] In this embodiment, it should be noted that the top of the conveying shaft 302 is connected to an external water pipe via a rotating connector, thereby enabling the water inlet 305 to connect with the external water pipe.

[0051] The steps for dissolving the dust suppressant are as follows:

[0052] Dust suppressant powder is poured into the feed hopper 102. At the same time, the external water pump and drive motor 202 are started synchronously. The drive motor 202 drives the central rotating shaft 203 and L-shaped stirring rod 204 to rotate. The central rotating shaft 203 drives the conveying shaft 302 to rotate synchronously through the driving pulley 308, the transmission toothed belt 309, and the driven pulley 307. The conveying shaft 302 drives the spiral blade 303 and the dispersing toothed disc 304 to rotate synchronously. The rotating spiral blade 303 can convey the dust suppressant powder inside the feed hopper 102 downwards.

[0053] At the same time, the external water pump delivers water through the external water pipe and rotary connector to the inside of the water inlet 305 and discharges it through the outlet 306. Under the action of centrifugal force of the rotating conveyor shaft 302, the water flow discharged from the outlet 306 diffuses outward and contacts the dust suppressant powder conveyed by the spiral blade 303 and impacts the bottom inner wall of the feed hopper 102 to achieve initial mixing.

[0054] The initial mixture intercepted by the inner wall of the bottom of the feed hopper 102 flows down along the inner wall of the feed hopper 102 and falls into contact with the dispersing toothed disc 304. The rotating dispersing toothed disc 304 will disperse the initial mixture a second time, causing it to fall into the mixing tank 101. The above operation can effectively prevent the dust suppressant powder from clumping.

[0055] The mixture entering the mixing tank 101 is thoroughly mixed by the agitation of the rotating L-shaped stirring rod 204, and can finally be discharged through the discharge valve 103.

[0056] Please refer to this carefully. Figures 2-4 Multiple L-shaped stirring rods 204 are evenly arranged along the circumference of the central rotating shaft 203. The length of the horizontal arm of the multiple L-shaped stirring rods 204 increases sequentially, and the running trajectory of the multiple L-shaped stirring rods 204 does not contact the dispersing toothed disc 304.

[0057] The vertical part of the L-shaped stirring rod 204, which has the longest horizontal arm, is in contact with the inner wall side of the mixing tank 101;

[0058] The inner wall of the mixing tank 101 is fixed with a scraper 104 that fits against the outer wall of the central rotating shaft 203. The scraper 104 and the feed hopper 102 are respectively distributed on both sides of the central rotating shaft 203, and the bottom horizontal height of the scraper 104 is higher than the horizontal height of the L-shaped stirring rod 204 with the shortest horizontal arm length.

[0059] In this embodiment: the mixture can be fully stirred and mixed by multiple L-shaped stirring rods 204, and the rotation of the L-shaped stirring rods 204 will not interfere with the scraper 104 or the dispersing toothed disc 304;

[0060] When the initial mixture is agitated a second time by the agitator 304, the splashed initial mixture will adhere to the inner wall of the mixing tank 101 and the outer wall of the central shaft 203. At this time, the vertical part of the L-shaped stirring rod 204 with the longest horizontal arm can be rotated to scrape the inner wall of the mixing tank 101, while the fixed scraper 104 can scrape the outer wall of the rotating central shaft 203. In this way, the initial mixture adhering to the inner wall of the mixing tank 101 and the outer wall of the central shaft 203 can be scraped off.

[0061] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
