Abstract
Description
Technical Field
[0001] This utility model relates to the field of flocculant technology, and more specifically, to an automatic flocculant addition device in the brine purification process. Background Technology
[0002] Flocculants are key chemical agents widely used in water treatment, wastewater treatment, and chemical production. Their core function is to achieve the aggregation and separation of suspended particles through physicochemical mechanisms. The following is a detailed analysis of their specific functions.
[0003] In existing technologies, flocculants are typically mixed with water to form a flocculant solution, which is then filled into the storage tank of the addition device. The flocculant solution is then discharged into a reaction tank as needed to react with the brine, thus collecting impurities in the brine. However, this setup requires a large-capacity storage tank to store the flocculant solution, avoiding the need for workers to repeatedly remix and refill the tank. This results in an excessively large footprint for the addition device, placing certain requirements on the site layout. Furthermore, the sedimentation that occurs during the use of the flocculant solution after a large amount is discharged into the storage tank at once is also a problem. Therefore, designing an automatic flocculant addition device for the brine purification process is a problem we currently need to solve. Utility Model Content
[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide an automatic flocculant addition device for brine purification. By setting control components, the device can achieve automatic flocculant addition. Furthermore, since the flocculant is mixed in real time, the need for a large storage tank can be avoided, making the overall structure of the addition device compact and space-saving. It can be directly installed on the top of the reaction tank, avoiding the problem of excessive space occupied by the addition device affecting the layout of the site, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic flocculant addition device for brine purification, comprising a reaction tank, a mounting frame fixedly installed on the top of the reaction tank, a motor fixedly installed on the top of the mounting frame, an agitator fixedly connected to the output end of the motor, the agitator penetrating the mounting frame and entering the interior of the reaction tank; and a control component for controlling the mixing and discharge of the flocculant solution, the control component being connected to the reaction tank.
[0006] In a preferred embodiment, the control assembly includes a tank body fixedly connected to the top of the reaction vessel, a cover plate being provided on the top of the tank body, and an annular baffle and a funnel-shaped baffle being fixedly connected inside the tank body, the annular baffle being disposed at the bottom of the funnel-shaped baffle.
[0007] In a preferred embodiment, a discharge component is fixedly connected to the bottom of the funnel-shaped partition, and a first sealing plate and a second sealing plate are slidably connected inside the discharge component, with the first sealing plate disposed on top of the second sealing plate.
[0008] In a preferred embodiment, a pusher is provided on one side of the discharge component, and a groove is formed on the outer wall of the pusher. The first sealing plate and the second sealing plate are slidably connected inside the groove.
[0009] In a preferred embodiment, the top of the annular partition is provided with a drain hole, the pusher is inserted into the drain hole, the bottom of the pusher is fixedly connected to a connecting rod, the outer wall of the connecting rod is sleeved with a sealing block, the outer wall of the connecting rod is fixedly installed with a top block, and the end of the connecting rod away from the cover plate is fixedly connected to a counterweight float.
[0010] In a preferred embodiment, a counterweight floating ring is slidably connected inside the tank, and a connecting rod is slidably connected inside the counterweight floating ring, with a connector hinged to one end of the connecting rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] like Figure 1 and Figure 2 As shown in the figure, an automatic flocculant addition device in the brine purification process of this utility model includes a reaction tank 1, a mounting frame 2 fixedly installed on the top of the reaction tank 1, a motor 3 fixedly installed on the top of the mounting frame 2, a stirring paddle 4 fixedly connected to the output end of the motor 3, and the stirring paddle 4 penetrating the mounting frame 2 and entering the interior of the reaction tank 1; and a control component, which is used to control the mixing and discharge of the flocculant solution and is connected to the reaction tank 1.
[0024] In this embodiment, as Figures 2 to 6As shown, the control assembly includes a tank body 5 fixedly connected to the top of the reaction vessel 1. A cover plate 6 is provided on the top of the tank body 5. An annular baffle 7 and a funnel-shaped baffle 8 are fixedly connected inside the tank body 5, dividing the interior of the tank body 5 into three chambers: a drainage chamber at the bottom of the annular baffle 7, a mixing chamber between the annular baffle 7 and the funnel-shaped baffle 8, and a material chamber at the top of the funnel-shaped baffle 8. The annular baffle 7 is located at the bottom of the funnel-shaped baffle 8, and a discharge component 9 is fixedly connected to the bottom of the funnel-shaped baffle 8. A first sealing plate 10 and a second sealing plate 11 are slidably connected inside the discharge component 9. 10 is set on the top of the second sealing plate 11. A pusher 12 is set on one side of the discharge component 9. A groove 13 is opened on the outer wall of the pusher 12. The first sealing plate 10 and the second sealing plate 11 are slidably connected inside the groove 13. A drain hole 14 is opened on the top of the annular partition 7. The pusher 12 is inserted into the drain hole 14. A connecting rod 15 is fixedly connected to the bottom of the pusher 12. The drain hole 14 matches the size of the connecting rod 15. A sealing block 16 is sleeved on the outer wall of the connecting rod 15. A top block 17 is fixedly installed on the outer wall of the connecting rod 15. A counterweight float 18 is fixedly connected to the end of the connecting rod 15 away from the cover plate 6.
[0025] In this embodiment, as Figures 3 to 6 As shown, a counterweight floating ring 19 is slidably connected inside the tank body 5. A connecting rod 20 is slidably connected inside the counterweight floating ring 19. One end of the connecting rod 20 is hinged to a connector 21. The connecting rod 20 consists of two hinged connecting rods. Two locking blocks are fixedly connected to the outer wall of one of the connecting rods inserted inside the counterweight floating ring 19. When the counterweight floating ring 19 descends to a certain position, the locking blocks on the connecting rod 20 pull the connecting rod 20 down, causing the connecting rod 20 to pull the connector 21 to rotate and open the seal on the water pipe 22, allowing water to flow into the mixing chamber through the water pipe 22. After the heavy floating ring 19 is driven to float and rise to reset by the water discharged into the mixing chamber, it will push the connecting rod 20 to reset through another locking block on the connecting rod 20. This will allow the connecting rod 20 to push the connecting piece 21 to reset and reseal the water pipe 22, stopping the water discharge. The water pipe 22 is fixedly connected inside the tank 5. The connecting piece 21 is fixedly connected to the end of the valve shaft inside the water pipe 22. The outer wall of the stirring paddle 4 is tensioned and connected to the V belt 23. The top of the annular partition 7 is rotatably connected to the stirring frame 24. The stirring frame 24 is tensioned and connected inside the V belt 23. The stirring frame 24 is sleeved on the outer wall of the pusher 12.
[0026] The working principle of the technical solution provided by this utility model is as follows:
[0027] Workers can pour brine into the reaction tank 1. As the brine level inside the reaction tank 1 gradually rises, it will cause the counterweight float 18 to rise as well. This causes the counterweight float 18 to slide and rise along the connecting rod 15 inside the tank body 5, sealing the drain hole 14 and closing the upper and lower cavities of the annular partition 7. The connecting rod 15 then causes the pusher 12 to rise. The rise of the pusher 12 will move the connected first sealing plate 10 and second sealing plate 11 through the slide groove 13. Due to the shape of the pusher 12, when the inclined section at the top of the pusher 12 pushes the first sealing plate 10 into the discharge part 9 through the slide groove 13 to seal the discharge part 9, the second sealing plate 11 will slide along the slide groove 13 on the vertical section of the pusher 12. The position inside the discharge component 9 will not change. When the position of the top of the vertical section of the pusher 12 connected to the inclined section moves relative to the position of the first sealing plate 10, the first sealing plate 10 completely enters the interior of the discharge component 9, and the sealing of the discharge component 9 is completed. At this time, the connection channel between the discharge component 9 and the funnel-shaped partition 8 is closed. As the pusher 12 continues to rise, the bottom inclined section of the pusher 12 will push the second sealing plate 11 to slide away along the interior of the discharge component 9, so that the second sealing plate 11 stops sealing the discharge component 9, and the flocculant between the first sealing plate 10 and the second sealing plate 11 inside the discharge component 9 falls into the mixing chamber. At this time, the second sealing plate 11 will slide along the groove 13 of the vertical section of the pusher 12, without changing its position inside the discharge component 9.
[0028] It should be noted that when the pusher 12 drives the second sealing plate 11 to stop sealing the discharge part 9 through the slide groove 13, the connecting rod 15 drives the top block 17 to rise the sealing block 16, so that the sealing block 16 rises to stop sealing the bottom outlet of the tank body 5, allowing the flocculant solution that has been mixed in the discharge chamber to be discharged into the interior of the reaction tank 1 for mixing. At this time, the brine level inside the reaction tank 1 reaches the predetermined height, and the filling of brine can be stopped and the motor 3 can be started, so that the motor 3 drives the stirring paddle 4 to mix the brine and flocculant solution inside the reaction tank 1.
[0029] It should be noted that when the stirring paddle 4 rotates, the stirring paddle 4 will drive the stirring frame 24 to rotate through the V belt 23, so that the stirring frame 24 can stir and mix the water and flocculant inside the mixing chamber to form a flocculant solution.
[0030] After the brine and flocculant solution have mixed and reacted, the brine can be drained to proceed to the next step. The draining of the brine causes the counterweight float 18 to lose buoyancy, and its own weight pulls the connecting rod 15 downwards to reset. The friction between the connecting rod 15 and the sealing block 16 causes the sealing block 16 to reset first (during the ascent of the connecting rod 15, the sealing block 16 is under pressure from the flocculant solution and will not rise with the connecting rod 15). This causes the connecting rod 15 to pull the pusher 12 to reset. The reset of the pusher 12, through the slide groove 13, causes the first sealing plate 10 and the second sealing plate 11 to reset. The second sealing plate 11 resets first to seal the discharge part 9, while the first sealing plate 10 resets later to open the seal on the discharge part 9. At this time, the flocculant at the top of the funnel-shaped baffle 8 falls and fills the interior of the discharge part 9. When the connecting rod 15 is fully reset, it stops sealing the drain hole 14, allowing the mixed flocculant solution inside the mixing chamber to pass through the drain hole 14. The flocculant solution is discharged into the drainage chamber and awaits subsequent use. After the flocculant solution is discharged from the mixing chamber, the counterweight floating ring 19 and the connecting rod 20 automatically control the connector 21 to open the seal of the water pipe 22, allowing the water pipe 22 to drain water into the mixing chamber (at this time, the drainage chamber is filled with flocculant solution, and water cannot be discharged into the drainage chamber through the drainage hole 14). When the water in the mixing chamber reaches the preset water level, the counterweight floating ring 19 floats up and drives the connecting rod 20 to automatically push the seal of the water pipe 22, stopping the drainage of the water pipe 22. At this time, the addition device completes one cycle, achieving the effect of automatically adding flocculant. Since the flocculant is mixed in real time, the setting of a large storage tank can be avoided, making the overall structure of the addition device compact and occupying a small area. It can be directly installed on the top of the reaction tank 1, avoiding the addition device occupying too much space and affecting the layout of the site. Moreover, since the flocculant is mixed in real time, it can effectively prevent the flocculant solution from settling, preventing the flocculant solution from settling and affecting the mixing reaction effect with the brine.
