[0011] Furthermore, the number of the first delivery pipe, the first magnetic levitation pump, and the flow meter is three.

[0012] According to the online mixing and homogenization system of this utility model embodiment, the magnetic levitation pump, due to its high speed adjustment ratio, can achieve a fairly wide flow adjustment range; by combining the first magnetic levitation pump with a flow meter, a stable flow output can be achieved without worrying about the influence between adjacent pipelines, thereby achieving high-precision online flow ratio, eliminating the need for a buffer tank, and reducing the overall size of the equipment; multiple liquid products (such as chemicals) are accurately proportioned through independent delivery pipelines and then enter the pump chamber of the second magnetic levitation pump. The ultra-high speed impeller can instantly and thoroughly mix the liquid and form a certain pressure to deliver it to the final point of use, reducing the use of a stirring tank; chemical mixtures of any proportion can be achieved with the same hardware configuration, and even if the types of chemicals are increased or decreased, it is only necessary to control the opening or closing of the valves of the corresponding independent branches.

[0013] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0015] Figure 2 This is a schematic diagram according to an embodiment of the present utility model. Detailed Implementation

[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0017] First, combine Figures 1-2 The online mixing and homogenizing system according to embodiments of the present invention is used for mixing and homogenizing liquids and has a wide range of applications.

[0018] like Figures 1-2 As shown, the online mixing and homogenizing system of this utility model embodiment includes:

[0019] Several first conveying pipes 1, the first conveying pipes 1 being used to convey liquid products;

[0020] Several first magnetic levitation pumps 2 are connected to the first delivery pipe 1 in a one-to-one correspondence;

[0021] Several flow meters 3 are respectively installed on the first delivery pipe 1;

[0022] The second conveying pipe 4 is connected to several first conveying pipes 1;

[0023] The second magnetic levitation pump 5 is connected to the second delivery pipe 4.

[0024] Furthermore, such as Figures 1-2 As shown, in this embodiment, a check valve 6 is also provided on the first delivery pipe 1. The check valve 6 is located at the rear end of the first magnetic levitation pump 2 to prevent liquid backflow.

[0025] Furthermore, in this embodiment, a control device (existing technology) is also included. The control device is communicatively connected to the first magnetic levitation pump 2, the second magnetic levitation pump 5, and the flow meter 3. The control device can control the on / off state of the first magnetic levitation pump 2 and the second magnetic levitation pump 5 and display the flow rate of the flow meter 3.

[0026] Furthermore, such as Figures 1-2 As shown, in this embodiment, there are three components: the first delivery pipe 1, the first magnetic levitation pump 2, and the flow meter 3. The number of these three components can be selected according to requirements.

[0027] Working principle: The chemical liquids enter the corresponding first magnetic levitation pump 2 through the corresponding first delivery pipe 1, and then enter the second magnetic levitation pump 5 to be mixed and sent to the final use point.

[0028] Above, refer to Figures 1-2 This invention describes an online mixing and homogenization system according to an embodiment of the present invention. The magnetic levitation pump, due to its high speed adjustment ratio, can achieve a fairly wide flow rate adjustment range. The combination of the first magnetic levitation pump 2 and the flow meter 3 enables stable flow output without concern for interference between adjacent pipelines, thus achieving high-precision online flow rate proportioning, eliminating the need for a buffer tank and reducing the overall equipment size. Multiple liquid products (such as chemicals) are accurately proportioned through independent delivery pipelines before entering the pump chamber of the second magnetic levitation pump 5. The ultra-high speed impeller can instantly and thoroughly mix the liquids and create pressure to deliver them to the final point of use, reducing the need for a mixing tank. Chemical mixtures of any proportion can be achieved with the same hardware configuration; even if the types of chemicals are increased or decreased, only the opening or closing of the corresponding independent branch valves needs to be controlled.
