Description

Technical Field

[0001] This utility model relates to the technical field of flocculant dosing, and in particular to a flocculant dosing device. Background Technology

[0002] Industrial development requires a large amount of industrial water, which in turn generates a large amount of wastewater. Both types of water require a series of treatments before they can be used or discharged. Flocculants are a class of agents widely used in water treatment and other fields. They can cause solutes, colloids, or suspended particles in water to aggregate into larger flocs or flocculent precipitates, thereby achieving solid-liquid separation and water purification.

[0003] The existing flocculant treatment process requires preparation of the flocculant, which involves mixing water and the flocculant together before pouring it into the wastewater for reaction. However, the manual preparation process is highly unstable, with inconsistent dosage and addition rate. If the flocculant is added too quickly or unevenly, it may lead to incomplete dissolution of the flocculant, resulting in flocculant clumping and waste. Utility Model Content

[0019] Please see Figures 1 to 5 The flocculant dosing device of this utility model includes a dissolving tank 1, a main water inlet pipe 2, a feeding assembly 3, a stirring assembly 4, and a quantitative dosing assembly 5; The dissolving tank 1 is provided with a conical channel 11, which divides the dissolving tank 1 into an upper chamber and a lower chamber. A valve 12 is provided on the conical channel 11. The main water inlet pipe 2 is fixedly installed on the side wall of the dissolving tank 1 and located in the upper chamber of the dissolving tank 1. The feeding assembly 3 is installed on the main water inlet pipe 2 and connected to the dissolving tank 1. The feeding assembly 3 is used to add flocculant dry powder into the dissolving tank 1. The stirring assembly 4 is installed in the dissolving tank 1 and is used to stir the water and flocculant mixture. The quantitative dosing assembly 5 is installed on the dissolving tank 1 and located in the lower chamber of the dissolving tank 1. The quantitative dosing assembly 5 is used to add flocculant solution to the wastewater at a fixed ratio. In this process, the feeding component 3 adds flocculant dry powder into the main water inlet pipe 2. The mixture of flocculant and water enters the upper chamber of the dissolving tank 1 along the main water inlet pipe 2. The stirring component 4 stirs the mixture of water and flocculant to make it evenly mixed. The valve is opened, and the flocculant solution enters the lower chamber of the dissolving tank 1 for maturation. The quantitative dosing component 5 mixes the solution in the lower chamber of the dissolving tank 1 with water according to a certain dosing ratio and adds it to the sewage, thereby achieving the purification treatment of sewage.

[0020] In this embodiment, the feeding assembly 3 includes a reagent tank 31, an ejector 32, and a siphon tube 33. The reagent tank 31 is fixedly installed at the top of the dissolving tank 1. The ejector 32 is installed on the main water inlet pipe 2. One end of the siphon tube 33 is connected to the bottom end of the reagent tank 31, and the other end is connected to the ejector 32. When water flows through the main inlet pipe 2, the water flow creates a negative pressure inside the ejector 32. The siphon pipe 33 draws the flocculant dry powder from the reagent tank 31 into the main inlet pipe 2 through the siphon effect. The flocculant dry powder and water then enter the dissolving tank 1 along the main inlet pipe 2.

[0021] In this embodiment, a one-way check ball 34 is provided inside the siphon tube 33. The one-way check ball 34 is located at one end of the siphon tube 33 near the medicine tank 31 and is slidably connected to the siphon tube 33. The one-way check ball 34 is installed at one end of the siphon pipe 33 that connects to the chemical tank 31 to prevent water from flowing back into the chemical tank 31.

[0022] In this embodiment, the stirring assembly 4 includes a drive shaft 41, a turbine blade 42, a first bevel gear 43, a stirring rod 44, and a second bevel gear 45. The drive shaft 41 is rotatably disposed inside the dissolving tank 1 and located directly below the main water inlet pipe 2. The turbine blade 42 is coaxially fixedly disposed on the drive shaft 41 and located at one end of the drive shaft 41 near the main water inlet pipe 2. The first bevel gear 43 is coaxially fixedly disposed on the drive shaft 41 and located at one end of the drive shaft 41 away from the turbine blade 42. The stirring rod 44 is vertically disposed and rotatably connected to the top of the dissolving tank 1. The second bevel gear 45 is coaxially fixedly disposed on the stirring rod 44 and meshes with the first bevel gear 43. Water enters from the inlet of the upper chamber of the dissolving tank 1. The water flow impacts the turbine blades 42 in the upper chamber, causing the turbine blades 42 to rotate. The turbine blades 42 drive the transmission shaft 41 to rotate, and the first bevel gear 43 rotates with the transmission shaft 41. The first bevel gear 43 meshes with the second bevel gear 45, and the first bevel gear 43 drives the second bevel gear 45 to rotate. The second bevel gear 45 is fixedly mounted on the stirring rod 44, and the stirring rod 44 rotates with the second bevel gear 45. This process stirs and mixes the water and flocculant entering the upper chamber of the dissolving tank 1, improving the mixing quality of the flocculant and water.

[0023] In this embodiment, a spiral guide plate 46 is provided inside the dissolving tank 1. Multiple spiral guide plates 46 are provided and are evenly arranged in a circumferential shape. The spiral guide plates 46 are fixedly connected to the dissolving tank 1 and are located in the upper cavity of the dissolving tank 1. The spiral guide plate 46 and the stirring rod 44 work together. When the stirring rod 44 rotates, the water flow forms a strong spiral rotating flow field under the guidance of the spiral guide plate 46, which increases the degree of water flow disturbance and makes the flocculant entering the upper cavity of the dissolving tank 1 fully mixed with the water. This effectively avoids the problem of local aggregation or uneven mixing of flocculant and further improves the mixing quality of flocculant and water.

[0024] In this embodiment, the quantitative dosing component 5 includes a regulating tank 50, an inlet pipe 51, an outlet pipe 52, a branch water pipe 53, a rotating shaft 54, a second turbine blade 55, a cam 56, a push rod 57, a push plate 58, and a return spring 59. The regulating tank 50 is located on one side of the dissolving tank 1. A metal diaphragm 501 is installed inside the regulating tank 50. The interior of the regulating tank 50 is divided into a power chamber and a reagent chamber. One end of the inlet pipe 51 is connected to the lower chamber of the dissolving tank 1, and the other end is connected to the reagent chamber of the regulating tank 50. The outlet pipe 52 is connected to the reagent chamber of the regulating tank 50 and is located at the end of the reagent tank 50 away from the inlet pipe 51. Both the inlet pipe 51 and the outlet pipe 52 are equipped with one-way valves. The branch water pipe 53 is located outside the dissolving tank 1 and is connected to the... The main water inlet pipe 2 is connected. The rotating shaft 54 ​​is rotatably mounted on the branch water pipe 53. The second turbine blade 55 is mounted inside the branch water pipe 53 and is coaxially fixedly connected to the rotating shaft 54. The cam 56 is mounted outside the branch water pipe 53 and is coaxially fixedly connected to the rotating shaft 54. One end of the push rod 57 passes through the regulating box 50 and is slidably connected to the regulating box 50. The push plate 58 is mounted inside the power cavity of the regulating box 50 and is fixedly connected to the push rod 57. The side wall of the push plate 58 away from the push rod 57 abuts against the metal diaphragm 501. The return spring 59 is mounted inside the power cavity of the regulating box 50 and is sleeved on the push rod 57. One end of the return spring 59 is fixedly connected to the regulating box 50 and the other end is fixedly connected to the push rod 57. In this process, the water flow in the branch pipe 53 impacts the second turbine blade 55, causing it to rotate. The second turbine blade 55 drives the rotating shaft 54 ​​to rotate, and the cam 56 rotates with the rotating shaft 54. The cam 56 periodically pushes the push rod 57 to move closer to the regulating box 50, compressing the return spring 59. At the same time, the push plate 59 squeezes the metal diaphragm 501, reducing the volume of the agent chamber in the regulating box 50 and forcing the agent out from the one-way valve of the outlet pipe 52. After the cam 56 disengages from the push rod 57, the return spring 59 returns the push rod 57 to its original position, increasing the volume of the agent chamber in the regulating box 50 and generating negative pressure. This draws the agent from the lower chamber of the dissolving tank 1 into the one-way valve of the inlet pipe 51, thereby achieving a dynamic balance between the flocculant dosage and the water flow rate, and thus realizing precise quantitative dosing of the agent.

[0025] In this embodiment, a filter screen is provided on the drug inlet pipe 51. The filter screen is located at one end of the drug inlet pipe 51 that connects to the dissolving tank 1, and is detachably connected to the drug inlet pipe 51. A filter screen is installed at the inlet of the inlet pipe 51 to prevent impurities in the lower cavity of the dissolving tank 1 from entering the inlet pipe 51, thereby preventing blockage of the one-way valve.

[0026] In this embodiment, a slag discharge port 13 is provided at the bottom of the dissolving tank 1, and the inclined slag collection trough 6 is provided inside the dissolving tank 1. The inclined slag collection trough 6 is located at the bottom of the dissolving tank 1. When the flocculant solution enters the lower chamber of the dissolving tank 1 for maturation, the impurities in the flocculant solution gradually sink down, and then enter the inclined slag collection tank 6 along the slope, and are discharged from the slag discharge port 13.

[0027] This flocculant dosing device includes a dissolving tank 1, a main inlet pipe 2, a feeding assembly 3, a stirring assembly 4, and a quantitative dosing assembly 5. The dissolving tank 1 is equipped with a conical channel 11, which divides the dissolving tank 1 into an upper chamber and a lower chamber. A valve 12 is installed on the conical channel 11. The feeding assembly 3 is used to add flocculant dry powder into the dissolving tank 1. The stirring assembly 4 is used to stir the mixture of water and flocculant. The quantitative dosing assembly 5 is used to add flocculant solution to the wastewater at a fixed ratio. The flocculant dosing device of this invention, through the design of each structure, makes it less likely that the flocculant will not dissolve completely due to excessively fast or uneven addition, thus avoiding drug clumping and waste. At the same time, the quantitative dosing assembly 5 achieves precise quantitative addition of the drug, ensuring the stability of the addition ratio.
