[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] like Figures 1 to 3 As shown, this embodiment discloses a dry powder-liquid mixing device, including a dry powder feeding device 1, a liquid feeding device 2, and a Venturi mixer 3. The Venturi mixer 3 includes a main flow pipe 31 and an inlet pipe 32 disposed on the main flow pipe 31. The liquid feeding device 2 is connected to the main flow pipe 31, and the dry powder feeding device 1 is connected to the inlet pipe 32. The liquid feeding device 2 is used to provide liquid with a flow rate to the Venturi mixer 3, and the dry powder feeding device 1 is used to provide dry powder to the Venturi mixer 3. The Venturi mixer 3 uses the change in the flow rate of the liquid to generate negative pressure to draw the dry powder into the Venturi mixer 3, thereby achieving uniform mixing of dry powder and liquid.

[0023] The dry powder mixing equipment in this embodiment uses a Venturi mixer 3 to mix dry powder and liquid. The Venturi mixer 3 has vacuum ejection capability and can use the fluid kinetic energy of the liquid to achieve ultra-fast mixing of dry powder and liquid, thereby breaking through the limit of mechanical stirring speed, having high mixing efficiency and structural reliability, and enabling the dry powder and liquid to be fully and evenly mixed, greatly improving economic benefits.

[0024] In this embodiment, the main flow pipe 31 of the Venturi mixer 3 includes a first straight section 311, a first tapered section 312, a second straight section 313, a second tapered section 314, and a third straight section 315 connected in sequence. The diameter of the second straight section 313 is smaller than the diameter of the first straight section 311, and the diameter of the third straight section 315 is equal to the diameter of the first straight section 311. The inlet pipe 32 is disposed on the first straight section 311, and the liquid feeding device 2 is connected to the first straight section 311. The Venturi mixer 3 has the maintenance-free characteristic due to the absence of moving parts, its structure is reliable, and it has a strong vacuum ejection capability and high mixing efficiency, with low overall energy consumption.

[0025] The dry powder feeding device 1 in this embodiment includes a dry powder tank 11, a dust collector 12, and a Roots blower 13. The outlet of the dust collector 12 is connected to the inlet of the Roots blower 13 via a pipe, and the discharge port of the dust collector 12 is connected to the outlet of the dry powder tank 11. The inlet of the dry powder tank 11 is connected to a suction pipe 14, and the discharge port of the dry powder tank 11 is connected to a discharge valve 15. A conveying box 16 is connected to the outlet of the discharge valve 15, and the conveying box 16 is connected to an inlet pipe 32 via a pipe. The Roots blower 13 is used to compress and transport gas to draw dry powder into the dry powder tank 11. During this process, the dry powder tank 11 is used to store dry powder, and the dust collector 12 is used to filter the dry powder within the dry powder tank 11 to avoid waste of dry powder and air pollution.

[0026] In this embodiment, a first pulse jet cleaning device 110 is installed inside the dry powder tank 11, and a second pulse jet cleaning device 120 is installed inside the dust collector 12. Both the first pulse jet cleaning device 110 and the second pulse jet cleaning device 120 are connected to an air compressor. Pulse jet cleaning is a prior art technology that utilizes compressed air to spray at high speed into the target object through a jet pipe for an extremely short time (typically 0.1 to 0.2 seconds), forming a strong airflow that causes the target object to undergo pulse expansion and vibration. In this embodiment, the first pulse jet cleaning device 110 is used to clean the dry powder tank 11, ensuring smooth discharge of the dry powder; the second pulse jet cleaning device 120 is used to clean the filter bags inside the dust collector 12, ensuring that the dry powder layer adhering to the surface of the filter bags detaches from the filter bags due to inertia and falls into the dry powder tank 11. This arrangement not only improves work efficiency but also eliminates the waste of dry powder and protects the working environment.

[0027] The air compression device in this embodiment includes an air compressor 17, a refrigerated dryer 18, and an air storage tank 19. The air compressor 17 is connected to the refrigerated dryer 18 through a pipe, and the refrigerated dryer 18 is connected to the air storage tank 19 through a pipe. The first pulse jet device 110 and the second pulse jet device 120 are respectively connected to the air storage tank 19.

[0028] In this embodiment, the dry powder tank 11 has two feed inlets, each connected to a suction pipe 14. To improve the ease of operation, valves are provided on each of the two suction pipes 14. Thus, the two feed inlets can be used simultaneously or individually. For example, one suction pipe 14 can be directly connected to the dry powder tanker truck, and the other suction pipe 14 can be connected to the dry powder ton bag. This arrangement not only meets different feeding methods but also greatly improves feeding efficiency.

[0029] The liquid feeding device 2 in this embodiment includes a water pump 21 and a liquid pipeline. One end of the liquid pipeline is connected to the main flow pipe 31, and the other end is connected to a liquid storage device (not shown in the figure). The water pump 21 is installed on the liquid pipeline. A liquid filter 24 is also installed on the liquid pipeline in this embodiment, located between the water pump 21 and the liquid storage device. By installing the liquid filter 24, the cleanliness and absence of impurities in the liquid are ensured.

[0030] Specifically, the liquid pipeline includes a main pipe 22 and two branch pipes 23 connected to the main pipe 22. The main pipe 22 is connected to a liquid storage device, and the two branch pipes 23 are used to connect to the first straight section 311 of the main pipe 31. A liquid filter 24 is installed on the main pipe 22, and a water pump 21 is installed on each of the two branch pipes 23. This arrangement facilitates the switching of the two branch pipes 23. On the other hand, the two branch pipes 23 can be connected to two Venturi mixers 3 respectively, and the feed box 16 below the dry powder tank 11 can also be connected to the two Venturi mixers 3 through pipelines, forming two sets of dry powder mixing devices, thereby improving the production efficiency of dry powder mixing.

[0031] In this embodiment, a connecting pipe 25 is provided between the two branch pipes 23, and a valve 26 is provided on the connecting pipe 25. Two water pumps 21 are located between the connecting pipe 25 and the main pipe 22. This arrangement facilitates switching to the other water pump 21 when one of the water pumps 21 fails, improving ease of use.

[0032] In use, the Roots blower 13 compresses and delivers gas to draw the dry powder into the dry powder tank 11. During this process, the dry powder tank 11 is used to store the dry powder, and the dust collector 12 is used to filter the dry powder in the dry powder tank 11 to avoid waste of the dry powder and air pollution. The dry powder in the dry powder tank 11 is discharged through the discharge valve 15 and enters the feed box 16. At the same time, the Venturi mixer 3 uses the fluid kinetic energy of the liquid to draw the dry powder into the Venturi mixer 3, thereby achieving ultra-fast mixing of the dry powder and the liquid, so that the dry powder and the liquid are fully and evenly mixed.

[0033] The above describes in detail a preferred embodiment of the dry powder mixing equipment of this utility model. Many other embodiments are also described but will not be elaborated upon here. In summary, the dry powder mixing equipment of this utility model can overcome the limits of mechanical stirring speed, has high mixing efficiency and structural reliability, and can fully and uniformly mix dry powder and liquid, greatly improving economic benefits.

[0034] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
