Description

Technical Field

[0001] This utility model relates to the field of sedimentation equipment technology, specifically a multi-stage sedimentation washing tank with deep impurity removal function. Background Technology

[0002] Sedimentation washing tanks are commonly used material handling equipment in industrial production, widely applied in mineral processing, chemical purification, and environmental water treatment. Combining gravity sedimentation with the action of washing liquid, they achieve the separation of materials from impurities and the purification of materials, providing clean materials or qualified liquids for subsequent production stages. They are one of the important pieces of equipment supporting continuous and refined industrial production.

[0003] Utility model patent CN219804260U discloses a settling tank, which includes a settling tank with a collection trough at the bottom. A collection box is fitted inside the collection trough, and the bottom of a lifting plate is fixedly connected to one side of the collection box. A groove is formed at the center of one side of the lifting plate, and several toothed blocks are installed in the groove. The toothed blocks are connected to a lifting assembly, which is installed in an installation groove. Sliding grooves are formed on both sides of the top of the settling tank, and through grooves are formed on opposite sides of the sliding grooves. Moving components are installed in the sliding grooves, and the moving components are connected to movable seats. A connecting plate is fixedly installed at the bottom of the movable seats, and a sliding plate is fixedly connected to the bottom of the connecting plate. The sliding plate is slidably installed inside the settling tank. This invention solves the problem that traditional settling tanks require regular cleaning of the sludge inside the settling tank, which is difficult and requires manual cleaning at the bottom of the settling tank, making it inconvenient to operate.

[0004] The current settling tank is a single-tank structure, which relies on a single settling process and cannot separate impurities of different particle sizes. Fine particles are easily suspended, resulting in limited impurity separation effect. In addition, the single-tank settling tank requires shutdown for each sludge cleaning operation and lacks a continuous impurity conveying structure, making it impossible to achieve continuous operation of "feeding-settling-impurity removal-discharge", resulting in low processing efficiency. In view of this, we propose a multi-stage settling and washing tank with deep impurity removal function. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage settling and washing tank with deep impurity removal function to solve the problems mentioned in the background art.

The protruding shaft is rotatably connected to the end of the swing arm, and the protruding rod is rotatably connected to the beginning of the swing arm. When the rotating wheel rotates, it pushes the movable frame to reciprocate at the top of the settling trough through the swing arm.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0017] Please see Figures 1-6A multi-stage settling and washing tank with deep impurity removal function includes a pair of seat plates 100, with several settling devices 200 fixed between the two seat plates 100. The settling devices 200 are arranged at equal intervals along the length of the seat plates 100. This arrangement, in conjunction with the subsequent conveying structure, lays the foundation for multi-stage continuous processing. The settling device 200 includes a settling tank 210, a vibrating screening mechanism 220 installed inside the settling tank 210 at an upper position, an impeller 230 located below the vibrating screening mechanism 220, and a baffle plate 240 located below the impeller 230. The settling tank 210 is used for settling operations, providing a closed space for material separation and mixing. The vibrating screening mechanism 220 is used for preliminary vibrating screening of materials, allowing materials that pass through the vibrating screening mechanism 220 to enter the settling tank 210. This can intercept some coarse particle impurities in advance, reducing subsequent settling pressure. The impeller 230 mixes the materials and liquid in the settling tank 210 during rotation, ensuring full contact between the drug and the materials, enhancing the drug's effect on impurities, and aiding in subsequent impurity separation. The baffle 240 divides the interior of the settling tank 210, with sediment settling below the baffle 240. This reduces the impact of the eddies generated by the impeller 230 during rotation on the sediment, preventing the re-suspension of settled impurities and ensuring settling stability.

[0018] like Figures 1-4 As shown, in this utility model, several connecting plates 110 are fixed between the two seat plates 100. The connecting plates 110 can enhance the connection strength between the two seat plates 100 and improve the stability of the overall structure. The bottom end of the settling tank 210 overlaps between the two seat plates 100 and is fixedly connected by bolts. The bolt connection method facilitates the disassembly, assembly, and maintenance of the settling tank 210. The bottom end of the settling tank 210 is funnel-shaped and is provided with a bottom sleeve 211. The funnel-shaped design can guide the sediment to gather towards the bottom sleeve 211, which is convenient for subsequent transportation. A conveying pipe 212 is connected to the outside of the bottom sleeve 211. The top end of the conveying pipe 212 is closed and a conveying motor 2121 is installed. A rotating shaft with helical blades is coaxially provided inside the conveying pipe 212. The top end of the rotating shaft is coaxially fixedly connected to the end of the output shaft of the conveying motor 2121. The conveying motor 2121 can drive the rotating shaft and the helical blades to rotate, providing power for sediment transportation. A discharge pipe is provided on the bottom surface of the top end of the conveying pipe 212, and a flexible hose 2122 is sleeved on the discharge pipe. The flexibility of the hose 2122 allows for flexible adjustment of the discharge direction to adapt to the feeding requirements of different settling devices 200. The end of the hose 2122 extends into another vibrating screening mechanism 220. When the conveying motor 2121 is working, the conveying pipe 212 transports the sediment in the current settling tank 210 to the next settling device 200, realizing continuous transfer of sediment without stopping the machine and supporting continuous operation.

[0019] like Figure 5As shown, specifically, the vibration screening mechanism 220 includes a movable frame 221 located at the top of the settling tank 210 and capable of moving along the length of the top of the settling tank 210, a swing motor 222 installed on the outside of the settling tank 210, and a sleeve frame 223 overlapping the movable frame 221. Several rollers 2211 are installed on the front and rear end faces of the movable frame 221. The outer circumferential surface of the rollers 2211 is provided with annular grooves. The top edge of the settling tank 210 extends into the grooves. The rollers 2211 move along the top edge of the settling tank 210 under the restriction of the grooves. The cooperation between the grooves and the edge of the settling tank 210 can guide the movement of the movable frame 221 and reduce the friction between the movable frame 221 and the settling tank 210, making the movement of the movable frame 221 smoother.

[0020] like Figure 2 , Figure 3 and Figure 5 As shown, furthermore, a protruding rod 2212 is fixed at the right end of the movable frame 221, providing a connection fulcrum for the swing arm 2222 to facilitate power transmission; a mounting base 214 is fixed at the right end face of the settling tank 210, and the swing motor 222 is mounted at the bottom end of the mounting base 214, which provides stable mounting support for the swing motor 222 to ensure the stability of the motor during operation; a rotating wheel 2221 is coaxially fixed at the end of the output shaft of the swing motor 222, and the outer periphery of the top surface of the rotating wheel 2221... A swing arm 2222 is hinged between the position and the movable frame 221. A convex shaft is provided on the outer periphery of the top surface of the rotating wheel 2221. The convex shaft is rotatably connected to the end of the swing arm 2222. A convex rod 2212 is rotatably connected to the head end of the swing arm 2222. When the rotating wheel 2221 rotates, it pushes the movable frame 221 to reciprocate at the top of the settling tank 210 through the swing arm 2222. The rotational motion of the swing motor 222 is converted into the reciprocating motion of the movable frame 221 through the mechanical transmission structure, which provides power for the vibratory screening and improves the screening effect.

[0021] like Figure 5 As shown, the frame 223 has a rectangular frame structure. Mesh plates 2231 are fixed to the four sides and bottom surface of the frame 223. The mesh plates 2231 can intercept particulate impurities in the material, achieving preliminary screening. Along the material conveying direction between the several settling devices 200, the aperture of the mesh plates 2231 in each settling device 200 gradually decreases. The front-stage mesh plate intercepts coarse particles, and the rear-stage mesh plate intercepts fine particles, achieving graded separation of impurities of different particle sizes. Several U-shaped hanging plates 2232 are fixed to the top edges of the front and rear sides of the movable frame 221. The hanging plates 2232 are hooked onto the movable frame 221. The U-shaped hooking structure facilitates the quick assembly and disassembly of the frame 223. When the mesh plates 2231 are clogged or need cleaning, the frame 223 can be directly removed for operation, reducing downtime.

[0022] like Figure 2and Figure 3 As shown, it is worth noting that the impeller 230 is rotatably connected to the settling tank 210, and the impeller 230 is coaxially connected to a rotating motor 231, which provides power for the rotation of the impeller 230. The rotating motor 231 is installed on the outside of the settling tank 210, and a sealed bearing is installed between the output shaft of the rotating motor 231 and the outer shell of the settling tank 210. The sealed bearing can prevent the liquid in the settling tank 210 from leaking through the gap between the shaft and the outer shell, while ensuring the smooth rotation of the output shaft.

[0023] like Figure 2 , Figure 3 and Figure 6 As shown, it is worth noting that the baffle 240 is inserted horizontally into the bottom of the settling tank 210. A trough 241 is provided on the baffle 240. The trough 241 is shaped like a frustum and has openings at both the top and bottom. The opening size at the top of the trough 241 is larger than the opening size at the bottom. The wall of the trough 241 is inclined. The frustum shape and inclined wall design can guide the material to fall smoothly and prevent the material from accumulating and blocking in the trough 241. The sediment falls into the settling tank 210 below the baffle 240 through the trough 241, realizing the initial separation of the sediment from the upper liquid. The baffle 240 can also prevent the vortex generated by the impeller 230 from affecting the sediment below.

[0024] like Figure 6 As shown, it should be added that the front and rear edges of the partition 240 are provided with protruding edges 242, and the inner walls of the front and rear sides of the lower part of the settling tank 210 are provided with slots. The cooperation between the protruding edges 242 and the slots can realize the precise positioning and stable installation of the partition 240, and prevent the partition 240 from shifting during use. A through-hole 213 is provided on the right end face of the lower part of the settling tank 210. The partition 240 inserts the protruding edges 242 on both sides into the two slots through the through-hole 213. The through-hole 213 provides operating space for the disassembly and assembly of the partition 240, which is convenient for subsequent cleaning or replacement of the partition 240. A sealing door 2131 is hinged to the outside of the through-hole 213. The sealing door 2131 can close the through-hole 213 to prevent liquid leakage in the settling tank 210, and at the same time protect the internal structure from external contamination.

[0025] It is worth noting that the conveyor motor 2121, the swing motor 222, and the rotary motor 231 involved in this utility model are all existing conventional technologies, and will not be described in detail in this utility model.

[0026] In this embodiment, the multi-stage settling washing tank with deep impurity removal function is used as follows: First, the material to be treated is put into the vibrating screening mechanism 220 of the first settling device 200. The swing motor 222 is started, and the rotating wheel 2221 drives the movable frame 221 to reciprocate through the swing arm 2222. The screen plate 2231 on the sleeve frame 223 performs preliminary screening of the material. Material and liquid that meet the aperture size fall into the settling tank 210. Then, the rotating motor 231 is started, and the impeller 230 rotates to stir the material and liquid. After mixing is completed, the impurities in the material gradually settle. The sediment falls through the trough 241 on the partition 240 into the bottom of the settling tank 210 below the partition 240. Then, the conveying motor 2121 is started, and the spiral blades in the conveying pipe 212 transport the sediment through the hose 2122 to the next settling device 200. The above screening, stirring and settling process is repeated. As the mesh size of the screen 2231 of the subsequent settling device 200 gradually decreases, fine particulate impurities are further separated. Finally, after all the settling devices 200 have completed their processing, the final sediment is discharged through the conveying pipe 212, completing the entire processing flow.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
