Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to a quantitative mixing device for water treatment agents. Background Technology

[0002] Water treatment agents are chemical substances added during the water treatment process to remove most of the harmful substances in water, such as corrosive substances, metal ions, dirt, and microorganisms, in order to obtain domestic or industrial water that meets the requirements.

[0003] Before treating water with a water treatment agent, the solid water treatment agent needs to be dissolved and diluted. Dissolve the solid water treatment agent in water according to the ratio and add an appropriate amount of dilution water to the required concentration.

[0004] In the prior art, patent CN221789112U discloses a water treatment agent stirring and dilution device, including a tank. A heating structure is installed inside the inner wall of the tank, and a connecting rod is located at the bottom end of the inner wall. A base is fixed to the bottom end of the tank, and a motor is installed in the middle of the bottom end of the tank. This invention, by incorporating a scraping structure, uses a motor to drive the connecting rod to rotate, which in turn drives a first connecting block to rotate. This first connecting block then drives a first scraper to rotate on the inner wall of the tank, scraping the inner wall. Furthermore, the connecting rod can drive a second connecting block to rotate, which in turn drives a second scraper to rotate at the bottom end of the tank, scraping the bottom. This achieves a more uniform dilution of the water treatment agent during use, preventing water treatment agent from adhering to the inner wall and settling at the bottom.

[0005] The technical solution proposed in the above-mentioned patent technology can achieve sufficient stirring in the actual dilution process of water treatment agent, but it cannot accurately control the amount of water treatment agent solid during the addition of water treatment agent solid and water. In view of this, this application proposes a water treatment agent quantitative mixing device. Utility Model Content

[0010] A weighing assembly for accurately weighing solid water treatment agents includes a fixed cylinder on the upper surface of a mixing cylinder and a weighing cylinder on the inner wall of the fixed cylinder. Two symmetrical weighing sensors are fixedly mounted on the inner bottom wall of the fixed cylinder.

[0013] By setting up a first motor and a spiral conveyor blade, the rotation of the first motor can drive the spiral conveyor blade to rotate, thereby allowing the solid water treatment agent in the storage cylinder to be fed out at a uniform and slow speed.

[0014] In a preferred embodiment, the water pump has a flexible hose at its inlet end that connects to an external water source, and an inlet pipe at its outlet end that extends into the mixing drum. A flow sensor is installed on the surface of the inlet pipe.

[0018] In a preferred embodiment, the stirring assembly includes a circular cavity formed inside the mixing cylinder, and four stirring rods arranged in a circumferential array rotating on the bottom wall of the circular cavity, with the top ends of the four stirring rods extending into the interior of the mixing cylinder, and stirring blades provided on the surface of the stirring rods.

[0019] By setting up stirring rods and stirring blades, the solid water treatment agent and water inside the mixing drum can be fully stirred and mixed by the stirring blades on the four stirring rods.

[0020] In a preferred embodiment, the lower surface of the mixing cylinder is provided with a second motor for driving the four stirring rods to rotate simultaneously, and the output end of the second motor extends into the interior of the circular cavity and is fixedly provided with an active toothed disc, and the outer surfaces of the four stirring rods are all fixedly provided with driven toothed discs that mesh with the active toothed discs.

[0021] By setting up an active gear disc and a driven gear disc, the rotation of the second motor can drive the four stirring rods to rotate simultaneously.

[0022] In a preferred embodiment, a plurality of springs are fixedly arranged in a circumferential array on the lower surface of the fixed cylinder and the upper surface of the mixing cylinder, and the top end of one of the stirring rods extends to the upper surface of the mixing cylinder and is fixedly provided with an eccentric disk for pushing the fixed cylinder.

[0023] By incorporating a spring and an eccentric disc, the rotation of the stirring rod can drive the eccentric disc to continuously push the fixed cylinder and weighing cylinder, facilitating material discharge.

[0026] Secondly, this utility model, by setting up a stirring component, can start a second motor to drive the stirring blades to quickly and fully stir the solid water treatment agent and water during the addition of the solid water treatment agent, thereby achieving rapid mixing. At the same time, it can drive the fixed cylinder and the weighing cylinder to vibrate back and forth, which facilitates the solid water treatment agent in the weighing cylinder to quickly enter the mixing cylinder, making it highly practical.

[0053] Example 2

[0054] Based on Example 1, and differing from Example 1 in that,

[0055] A water treatment agent metering mixing device further includes:

[0056] A stirring assembly 700 is used to mix water treatment agent solids added to the mixing drum 100 with water.

[0057] Reference Figure 2 In a preferred embodiment, the stirring assembly 700 includes a circular cavity opened inside the mixing cylinder 100, and four stirring rods 701 arranged in a circumferential array rotating on the bottom wall of the circular cavity, with the top ends of the four stirring rods 701 extending into the interior of the mixing cylinder 100, and stirring blades 702 provided on the surface of the stirring rods 701.

[0058] By setting up stirring rods 701 and stirring blades 702, the solid water treatment agent and water inside the mixing cylinder 100 can be fully stirred and mixed by the stirring blades 702 on the four stirring rods 701.

[0059] Reference Figure 2 and Figure 4 In a preferred embodiment, the lower surface of the mixing cylinder 100 is provided with a second motor 703 for driving four stirring rods 701 to rotate simultaneously, and the output end of the second motor 703 extends into the interior of the circular cavity and is fixedly provided with an active toothed disc 704. The outer surfaces of the four stirring rods 701 are all fixedly provided with driven toothed discs 705 that mesh with the active toothed discs 704.

[0060] By setting an active gear disc 704 and a driven gear disc 705, the rotation of the second motor 703 can drive the four stirring rods 701 to rotate simultaneously.

[0061] Reference Figure 2 In a preferred embodiment, a plurality of springs 706 are fixedly arranged in a circumferential array on the lower surface of the fixed cylinder 601 and the upper surface of the mixing cylinder 100, and the top end of a stirring rod 701 extends to the upper surface of the mixing cylinder 100 and is fixedly provided with an eccentric disk 707 for pushing the fixed cylinder 601.

[0062] By setting spring 706 and eccentric disk 707, the rotation of stirring rod 701 can drive eccentric disk 707 to continuously push fixed cylinder 601 and weighing cylinder 602, which facilitates material discharge.

[0063] In this embodiment, by setting up a stirring assembly 700, during the process of adding solid water treatment agent, the second motor 703 can be started to drive the stirring blade 702 to quickly and fully stir the solid water treatment agent and water, thereby achieving rapid mixing. At the same time, it can drive the fixed cylinder 601 and the weighing cylinder 602 to vibrate back and forth, which facilitates the solid water treatment agent in the weighing cylinder 602 to quickly enter the mixing cylinder 100, making it highly practical.

[0064] Working principle: When diluting solid water treatment agents, this device can pre-set the values ​​of flow sensor 502 and weighing sensor 603 via PLC controller 606. Then, water pump 500 is started to deliver water from an external water source to mixing drum 100 through inlet pipe 501. When the value of flow sensor 502 reaches the pre-set value via PLC controller 606, flow sensor 502 transmits a signal to PLC controller 606, which automatically shuts off water pump 500, thereby controlling the dilution of water volume. To achieve precise control, the first motor 202 is started and the first electromagnetic control valve 400 is opened. The rotation of the first motor 202 drives the rotating rod 201 to rotate, which in turn drives the screw conveyor 203 to rotate, slowly conveying the solid water treatment agent inside the storage cylinder 200 to the weighing cylinder 602. When the weighing sensor 603 displays that the weight of the solid water treatment agent in the weighing cylinder 602 has reached the value preset by the PLC controller 606, the weighing sensor 603 transmits a signal to the PLC controller 606. The automatic control system closes the first motor 202 and the first electromagnetic control valve 400, and automatically opens the second electromagnetic control valve 605, allowing the solid water treatment agent in the weighing cylinder 602 to enter the mixing cylinder 100. This achieves precise control over the amount of solid water treatment agent, enabling the device to precisely control both the amount of solid water treatment agent and the amount of water during dilution, ensuring accurate proportions of the diluted water treatment agent. Furthermore, during the addition of the solid water treatment agent, the second motor 703 is activated to drive the active gear disc 704 to rotate. The rotation of the stirring rod 701 drives the four driven toothed discs 705 and the stirring rod 701 to rotate. The rotation of the stirring rod 701 drives the stirring blade 702 to quickly and thoroughly stir the solid water treatment agent and water, achieving rapid mixing. At the same time, the rotation of one stirring rod 701 drives the eccentric disc 707 to rotate. The rotation of the eccentric disc 707, under the action of the spring 706, realizes the continuous reciprocating pushing of the fixed cylinder 601, thereby causing the fixed cylinder 601 and the weighing cylinder 602 to vibrate back and forth. This facilitates the rapid entry of the solid water treatment agent in the weighing cylinder 602 into the mixing cylinder 100, making it highly practical.

[0065] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
