[0002] Flocculant dilution is generally carried out using a three-chamber continuous preparation equipment. The mass concentration of the flocculant solution is controlled by controlling the water flow rate and the amount of flocculant fed. However, the control accuracy of the mass concentration of the flocculant solution is poor. The equipment has three chambers arranged in parallel and feeds through overflow. On the one hand, due to the stirring effect in each chamber, there are technical problems such as unmixed solution entering adjacent chambers or solution that has not been fully matured being fed out. The quality of the flocculant solution cannot be guaranteed. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a flocculant dilution and dosing machine that accurately measures the dosage of flocculant and water, ensuring the concentration and quality of the flocculant solution.

[0004] The technical solution of this utility model is as follows:

[0012] In a further technical solution, the feeding storage box is vertically provided with alternating partitions on both sides along the direction from the front to the rear, and the partitions divide the inside of the feeding storage box into a serpentine channel.

[0013] In a further technical solution, observation ports are provided on the top of the feeding storage tank and the top of the maturation storage tank, respectively.

[0014] In a further technical solution, a vibrator is provided on the outside of the storage hopper.

[0021] The beneficial effects of this utility model are:

[0022] 1. The weighing sensor monitors the dosage of the flocculant in the storage hopper. The water inlet pipe measures and introduces water into the mixing tank via a water flow meter. Level gauges three and four determine the high and low liquid levels in the mixing tank, respectively, to determine the water volume and facilitate the preparation of flocculant solutions of specified concentrations. After stirring by the agitator, the flocculant is homogenized and diluted to meet quality requirements. Level gauge two monitors the low liquid level in the maturation storage tank. When the solution in the maturation storage tank falls below the low liquid level, discharge pipe two is opened to discharge the solution from the mixing tank into the maturation storage tank. Level gauge one monitors the low liquid level in the feeding storage tank. Discharge pipe two is closed, and the flocculant is diluted again to prepare the flocculant solution for the next cycle. This equipment adopts a static cycle precise metering and preparation process for the flocculant. Water is metered by high and low liquid levels, and mass is calculated from volume. The total feed amount is monitored by adding the flocculant, ensuring accurate metering, precise material ratio, and better control of the concentration of diluted flocculant.

[0023] 2. The flocculant dilution preparation adopts a top-to-bottom fully gravity-flow discharge method, which will not damage the macromolecular chain structure of the flocculant and is conducive to energy saving;

[0024] 3. The storage tanks are layered, consisting of a maturation storage tank and a feeding storage tank, which are connected vertically and allow for gravity discharge. The maturation storage tank has a through-type structure, while the feeding storage tank has a serpentine channel formed by partitions, allowing the solution to be fed in sequence for deep maturation and ensuring solution performance.

[0025] 4. The observation port allows for easy observation of the solution conditions inside the feeding storage tank and the maturation storage tank;

[0026] 5. The vibrator increases the fluidity of the flocculant in the storage hopper. Attached Figure Description

Detailed Implementation

[0032] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0033] Example:

[0034] like Figures 1-2As shown, a flocculant dilution and dosing machine includes a water inlet structure, a support 10, a storage hopper 20, a mixing tank 30, a maturation storage tank 40, a feeding storage tank 50, and a discharge structure. The feeding storage tank 50 is located on top of the support 10. A level gauge 51 is provided on one side of the bottom of the feeding storage tank 50. A drain port 52 with a drain valve is also provided on the feeding storage tank 50 below the level gauge 51, for discharging residual solution after discharge, or for... After cleaning, sewage is discharged; the feeding storage tank 50 is vertically equipped with alternating partitions 53 on both sides from front to back, which divide the interior of the feeding storage tank 50 into a serpentine channel; the maturation storage tank 40 is located on top of the feeding storage tank 50, and the bottom of the maturation storage tank 40 is equipped with a discharge pipe connecting to the feeding storage tank 50, and a level gauge 41 is located on one side of the bottom of the maturation storage tank 40; the mixing tank 30 is located on top of the maturation storage tank 40. The mixing tank 30 has a mixing mechanism in the middle, which includes a mixing motor 31 and a stirrer 32. The mixing motor 31 is located at the top center of the mixing tank 30, and the stirrer 32 is driven by the mixing motor 31 and located inside the mixing tank 30. The top and bottom of the mixing tank 30 are respectively equipped with a level gauge 33 and a level gauge 44. The bottom of the mixing tank 30 is equipped with a discharge pipe 2 that connects to the maturation storage tank 40. The discharge pipe 1 and discharge pipe 2 are respectively equipped with discharge valves. The storage hopper 20 is located on one side of the top of the mixing tank 30 and can be supported by a bracket. The storage hopper 20 is connected to the mixing tank 30 through a feeding mechanism. The bottom of the storage hopper 20 is equipped with a weighing sensor 22, which can be electrically connected to an audible and visual alarm. The volume of the feeding storage tank 50 is greater than or equal to the volume of the maturation storage tank 40, and the volume of the maturation storage tank 40 is greater than or equal to the volume of the mixing tank 30.

[0035] The water inlet structure includes an inlet pipe 60, a water flow meter 61, a solenoid valve 62, and a basket filter 63. The basket filter 63, the water flow meter 61, and the solenoid valve 62 are arranged sequentially along the conveying direction of the inlet pipe 60. The two ends of the inlet pipe 60 are connected to the mixing tank 30 and the water source, respectively. The discharge structure includes a discharge pipe 70 located at the bottom of the feeding storage tank 50. A pump body and a chemical flow meter 72 are respectively installed on the discharge pipe 70.

[0036] The working principle of the above technical solution is as follows:

[0037] In this dosing machine, the flocculant dry powder is stored in the storage hopper 20. The weighing sensor 22 monitors the remaining dosage in the storage hopper 20. When the remaining dosage is less than the amount needed for one cycle of solution preparation, the equipment issues an audible and visual alarm signal to prompt the addition of material to the storage hopper 20. When the amount of flocculant stored is greater than the amount needed for one cycle of preparation, the flocculant dilution concentration N% is set. During preparation, the stirring motor 31 is first turned off, and the solenoid valve 62 is opened. The dilution water is measured by the water flow meter 61 and enters the inlet pipe 60. After being filtered by the basket filter 63, the water enters the stirring tank 30. When the level gauge 33 detects that the water level has reached the stirring tank, the flocculant is added to the tank. When the liquid level in tank 30 is high, water intake is stopped, and the volume is converted to mass. The mass of water in tank 30 at this time is recorded as M1. The stirring motor 31 is turned on, and the weight of the drug in hopper 20, M2, is obtained through the weighing sensor 22. Based on the diluted mass concentration, the amount of drug added in this cycle, M1 × N%, is calculated and recorded as M3. Then, the feeding mechanism is turned on to start feeding the drug. During the drug feeding process, the weighing sensor 22 continuously monitors the remaining drug mass in hopper 20. When the drug mass given by the feeding mechanism is equal to M3, feeding is stopped, and the drug feeding for this cycle is completed. The stirrer 32 continues to stir until the drug is homogenized and diluted to meet the quality requirements.

[0038] When the homogenization and dilution of the reagent in the mixing tank 30 reaches the required quality level, it can enter the unloading waiting state. At this time, the unloading pipe 2 is closed. When the level gauge 2 41 detects that the liquid level in the maturation storage tank 40 is higher than the low level, the mixing tank 30 remains in the unloading waiting state. When the level gauge 2 41 detects that the liquid level in the maturation storage tank 40 is lower than the low level, the unloading pipe 2 is opened to empty the reagent solution in the mixing tank 30. When the liquid level is detected to be lower than the level gauge 4 34 of the mixing tank 30, the unloading pipe 2 is closed, and the next cycle of reagent dilution preparation begins. The solution entering the maturation storage tank 40 enters the feeding storage tank 50 by gravity flow and is discharged sequentially by the pump body on the discharge pipe 70.

[0039] In another embodiment, the top of the mixing tank 30, the top of the feeding storage tank 50, and the top of the maturation storage tank 40 are respectively provided with observation ports, and the observation ports are hinged with covers, which are normally closed before and after observation.

[0040] The observation port allows for easy observation of the solution conditions inside the mixing tank 30, the feeding storage tank 50, and the maturation storage tank 40.

[0041] In another embodiment, such as Figure 1 As shown, a vibrator 23 is provided on the outside of the storage hopper 20; the feeding mechanism includes a screw feeder 21 located at the bottom of the inner side of the storage hopper 20. The driving device of the screw feeder 21 can be a variable frequency motor, and the output end of the screw feeder 21 can be equipped with a humidifier that connects to the inside of the mixing tank 30.

[0042] The vibrator 23 can increase the fluidity of the flocculant in the storage hopper 20; the feeding speed of the agent can be controlled by adjusting the frequency of the variable frequency motor of the screw feeder 21, and the agent can be added quantitatively within a set time.

[0043] In another embodiment, such as Figure 1-2 As shown, the discharge pipe 70 includes a connecting section 73, a branch section 74 and an outlet section 75 in sequence along the conveying direction. The branch section 74 includes two parallel sections. The two ends of the parallel branch section 74 are connected in series with the connecting section 73 and the outlet section 75, respectively. A switching valve 76 is provided on the branch section 74. The pump body is a screw pump 71, which is provided on the branch section 74. The drug flow meter 72 is provided on the outlet section 75.

[0044] The switching valve 76 can be selected to open the branch section 74 for discharging. The drug flow meter 72 on the discharge pipe 70 measures the feed flow rate. The solution feed flow rate is controlled by adjusting the working frequency of the screw pump 71 drive motor.

[0045] In another embodiment, such as Figure 1 As shown, a sampling port 77 is also provided on the branch section 74, and a sampling valve is provided at the sampling port 77.

[0046] It facilitates sampling of the diluted drug solution.

[0047] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
