Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a water circulation structure for a flotation washing tank. Background Technology

[0002] During the processing of natural rubber, the rubber bales become contaminated with mud and impurities during collection, transportation, and initial crushing. Before entering the kneading and granulation processes, the rubber compound needs to be cleaned. Therefore, a flotation tank is added to the natural rubber processing line to clean the rubber compound. In existing technology, the water in a single flotation tank is typically used for an extended period. After the mud and impurities separate from the rubber compound, they settle to the bottom of the tank. The tank is then drained and cleaned after the water change cycle. This process can easily lead to the water flow re-mixing the sediment and impurities deposited at the bottom into the natural rubber compound, causing secondary pollution. Furthermore, the water utilization efficiency of the flotation tank is low. In response to this situation, Chinese Patent Publication No. CN206066759U discloses a natural rubber stirring, washing, and filtering device, which includes a washing tank and a material retrieval machine installed on the washing tank. A truncated cone with the top of the tank wall flush with the center of the washing tank is set, and a bracket is set on the top of the truncated cone. The two ends of the bracket are fixed to the top of the tank wall. The washing tank is provided with a feed inlet and a water supply pipe. A sewage discharge trough is set at the bottom of the washing tank, and a foreign matter separation trough is set on the side wall of the washing tank.

[0003] The aforementioned disclosed technologies do not utilize the wastewater after discharge, thus failing to improve the water utilization efficiency in the flotation tank and easily leading to increased water costs. Utility Model Content

[0004] The purpose of this invention is to solve the problem that water in the existing flotation tank is difficult to recycle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water circulation structure for a flotation tank includes a flotation tank, a base on the flotation tank, a first motor on the base, a paddle shaft on the output shaft of the first motor, a plurality of paddles on the paddle shaft, a water pump on the flotation tank, an input end of the water pump connected to the flotation tank, and a flocculation device on the output end of the water pump. The flocculation device includes a flocculation tank with an outlet connected to the flotation tank, a stirring device inside the flocculation tank, a water injection device inside the stirring device connected to the water pump, a chemical dosing port on the flocculation tank, a plurality of baffles on the inner wall of the flocculation tank, and a waste discharge assembly at the waste discharge end of the flocculation tank.

[0007] Preferably, the stirring device includes a stirring rod with spiral blades, the stirring rod is connected to the flocculation tank, the flocculation tank is equipped with a second motor, and a transmission assembly is connected between the output end of the second motor and the stirring rod. The water injection device includes a sewage pipe, the stirring rod is a hollow tube, the sewage pipe is connected to the stirring rod, the inlet end of the sewage pipe is connected to the outlet end of the water pump, the outlet end of the sewage pipe is equipped with an adapter, the adapter has a bearing inside, the bearing is sleeved on one end of the stirring rod, the adapter is stationary relative to the stirring rod, and the stirring rod rotates within the flocculation tank around its own axis.

[0008] Preferably, the transmission assembly includes a first transmission wheel and a second transmission wheel, the first transmission wheel is connected to the stirring rod, the second transmission wheel is connected to the output shaft of the second motor, and a first transmission belt is provided between the first transmission wheel and the second transmission wheel.

[0009] Preferably, the stirring rod is provided with a plurality of stirring blades, which are evenly distributed among the spiral blades.

[0010] Preferably, the cross-section of the baffle is inverted V-shaped.

[0011] Preferably, the flocculation tank is equipped with a filter plate.

[0012] Preferably, the waste discharge assembly includes a waste discharge tank, a spiral feeding rod inside the waste discharge tank connected to the top of the waste discharge tank, a third motor on the waste discharge tank, a third drive wheel on the output end of the third motor, a fourth drive wheel on the spiral feeding rod, a second drive belt between the fourth drive wheel and the third drive wheel, a feed inlet on the waste discharge tank connected to the waste discharge end of the flocculation tank, and a discharge outlet on the waste discharge tank located on the top wall of the waste discharge tank.

[0013] The beneficial effects proposed by this utility model are as follows:

[0014] When the natural rubber raw material falls into the flotation tank, the first motor starts and the output shaft of the first motor rotates, driving the paddle shaft to rotate, so that the paddle stirs the water surface of the flotation tank. During the stirring process, the natural rubber raw material is washed by the tank water, and its mud and sand impurities are separated from the rubber material and mixed with water to form a mud-water mixture, which gradually settles into the flotation tank. Subsequently, the pump's suction end is located at the bottom of the flotation tank. After the pump starts, the mud-water mixture is drawn into the flocculation device. During this process, since the water injection device is connected to the pump's outlet, the mud-water mixture is injected into the flocculation tank. Simultaneously, flocculant is added to the flocculation tank through the dosing port to mix and react with the mud-water mixture. Then, the stirring device starts to stir the mud-water mixture, allowing it to fully react with the flocculant and accelerating the flocculation process. At the same time, several baffles are provided on the inner wall of the flocculation tank. These baffles can partially obstruct the movement trajectory of the mud-water mixture during the stirring process, change the water flow direction, increase multiple turbulent water flow areas, improve the stirring efficiency of the stirring device, and increase the reaction efficiency between the flocculant and the mud-water mixture. After the flocculant reacts with the mud-water mixture, it forms flocs that settle at the bottom of the flocculation tank and are discharged by the waste discharge component. The separated clear water remains on the upper layer of the flocculation tank and flows out through the outlet, returning to the flotation tank. This process achieves water recycling in the flotation tank, improving water utilization and reducing water costs. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1 to 5A water circulation structure for a flotation tank 1 includes a flotation tank 1, a base 2 on the flotation tank 1, a first motor 3 on the base 2, a paddle shaft 4 on the output shaft of the first motor 3, a plurality of paddle blades 5 on the paddle shaft 4, a water pump 6 on the flotation tank 1, the input end of the water pump 6 being connected to the flotation tank 1, and a flocculation device 7 on the output end of the water pump 6; the flocculation device 7 includes a flocculation tank 9, an outlet 10 connected to the flotation tank 1, a stirring device inside the flocculation tank 9, a water injection device inside the stirring device, the water injection device being connected to the water pump 6, a chemical dosing port 11 on the flocculation tank 9, a plurality of baffles 12 on the inner wall of the flocculation tank 9, and a waste discharge assembly 8 at the waste discharge end of the flocculation tank 9. Specifically, when the natural rubber raw material falls into the flotation tank 1, the first motor 3 starts and rotates through the output shaft of the first motor 3, which drives the shaft 4 of the paddle 5 to rotate, so that the paddle 5 stirs the water surface of the flotation tank 1. During the stirring process, the natural rubber raw material is washed by the tank water, and its mud and sand impurities are separated from the rubber material and mixed with water to form a mud-water mixture, which gradually settles into the flotation tank 1. Subsequently, the pump 6 is positioned at the bottom of the flotation tank 1. After the pump 6 is started, the mud-water mixture is drawn into the flocculation device 7. During this process, since the water injection device is connected to the outlet of the pump 6, the mud-water mixture is injected into the flocculation tank 9. At the same time, the flocculant is added into the flocculation tank 9 through the dosing port 11 to mix and react with the mud-water mixture. Then, the stirring device is started to stir the mud-water mixture, allowing it to react fully with the flocculant and accelerating the flocculation process. Meanwhile, several baffles 12 are provided on the inner wall of the flocculation tank 9. The baffles 12 can partially obstruct the movement trajectory of the mud-water mixture during the stirring process, change the direction of water flow, increase multiple turbulent water flow areas, improve the stirring efficiency of the stirring device, and increase the reaction efficiency between the flocculant and the mud-water mixture. After the flocculant reacts with the mud-water mixture, it forms flocs that settle at the bottom of the flocculation tank 9 and are discharged by the waste discharge component 8. The separated clear water remains on the upper layer of the flocculation tank 9 and finally flows out through the outlet 10, returning to the flotation tank 1. This process achieves water recycling in the flotation tank 1, improving water utilization and reducing water costs.

[0023] Specifically, the stirring device includes a stirring rod 13 with spiral blades 14. The stirring rod 13 is connected to the flocculation tank 9, and the flocculation tank 9 is equipped with a second motor 15. A transmission assembly is connected between the output end of the second motor 15 and the stirring rod 13. The water injection device includes a sewage pipe 16. The stirring rod 13 is a hollow pipe, and the sewage pipe 16 is connected to the stirring rod 13. The inlet end of the sewage pipe 16 is connected to the outlet end of the water pump 6. The outlet end of the sewage pipe 16 is equipped with an adapter 17, and a bearing 18 is provided inside the adapter 17. The bearing 18 is sleeved on one end of the stirring rod 13. The adapter 17 is stationary relative to the stirring rod 13, and the stirring rod 13 rotates within the flocculation tank 9 around its own axis. After the second motor 15 starts, its output shaft rotates, driving the stirring rod 13 to rotate via the transmission assembly. The stirring rod 13 is equipped with spiral blades 14, which transport the formed flocs to the waste discharge assembly 8 during the stirring of the mud-water mixture. During the operation of the stirring device, since the stirring rod 13 is a hollow rod with an opening at one end, when the mud-water mixture is injected through the sewage pipe 16, the stirring rod 13 injects the mud-water mixture into the flocculation tank 9. This ensures that the reaction zone between the mud-water mixture and the flocculant is located at the bottom of the flocculation tank 9, without affecting the upper clear water zone. Since the stirring rod 13 is always rotating under the action of the second motor 15, and the sewage pipe 16 connects the stirring rod 13 to the water pump 6, in order to avoid pipe twisting, which could cause pipe blockage or damage, an adapter 17 is provided between the sewage pipe 16 and the stirring rod 13. The adapter 17 is fixedly connected to the sewage pipe 16, and the adapter 17 is connected to the stirring rod 13 through a bearing 18. When the stirring rod 13 is rotating, due to the action of the bearing 18, the adapter 17 and the sewage pipe 16 remain stationary relative to the stirring rod 13. This ensures that the operation of the stirring rod 13 is not affected during water injection and also reduces the risk of pipe twisting.

[0024] Specifically, the transmission assembly includes a first transmission wheel 19 and a second transmission wheel 21. The first transmission wheel 19 is connected to the stirring rod 13, and the second transmission wheel 21 is connected to the output shaft of the second motor 15. A first transmission belt 20 is provided between the first transmission wheel 19 and the second transmission wheel 21. When the output shaft of the second motor 15 rotates, it drives the second transmission wheel 21 to rotate. Through the connection of the first transmission belt 20, the first transmission wheel 19 rotates, thereby driving the stirring rod 13 to start. The space optimization of the flocculation tank 9 through the transmission assembly is beneficial to the connection and operation of the sewage pipe 16 and the stirring rod 13.

[0025] Specifically, the stirring rod 13 is provided with a plurality of stirring blades 22, which are evenly distributed among the spiral blades 14. Adding the stirring blades 22 to the existing spiral blades 14 can improve the stirring efficiency of the stirring rod 13.

[0026] Specifically, the cross-section of the baffle 12 is an inverted V-shape. This improves the stirring efficiency of the stirring device and increases the reaction efficiency between the flocculant and the mud-water mixture. When the baffle 12 is set to an inverted V-shape, in the water flow direction, it can improve the feeding efficiency of the spiral blades 14, allowing the flocculant to flow to the reaction zone at the bottom of the flocculation tank 9. In the reverse water flow direction, it can block the backflow of the mud-water mixture and prevent flocculent clumps from flowing back into the clear water area.

[0027] Specifically, the flocculation tank 9 is equipped with a filter plate 31. The filter plate 31 is used to separate the clear water area and the flocculation area of ​​the flocculation tank 9, reducing the risk of clear water mixing with flocculated impurities and reducing the risk of blockage of the outlet 10.

[0028] Specifically, the waste discharge assembly 8 includes a waste discharge tank 23, inside which is a spiral feeding rod 25 connected to the top of the waste discharge tank 23. A third motor 24 is mounted on the waste discharge tank 23, and a third transmission wheel 28 is mounted on the output end of the third motor 24. A fourth transmission wheel 30 is mounted on the spiral feeding rod 25, and a second transmission belt 29 is provided between the fourth transmission wheel 30 and the third transmission wheel 28. A feed inlet 26 is mounted on the waste discharge end of the flocculation tank 9, and a discharge outlet 27 is mounted on the top wall of the waste discharge tank 23. When the output shaft of the third motor 24 rotates, it drives the third transmission wheel 28 to rotate. Through the connection of the second transmission belt 29, the fourth transmission wheel 30 rotates. At this time, the spiral feed rod 25 rotates, lifting the flocculent clumps placed at the bottom of the waste discharge tank 23 to the discharge port 27 for discharge. The feed port 26 is used to input the flocculent clumps discharged from the flocculation tank 9. The waste discharge assembly 8 can separate the flocculent clumps from the water, improving the efficiency of clean water generation.

[0029] 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.
