Technical Field

[0001] This utility model belongs to the field of material mixing and dispersing equipment, and specifically relates to a material mixing and dispersing device. Background Technology

[0002] In fields such as petrochemicals, metallurgy, new energy, pharmaceuticals, and construction, uniform dispersion and mixing of materials are extremely important for material processing and use. Currently, commonly used material dispersion devices include mechanical stirring and ultrasonic dispersion. However, commonly used mechanical stirring and ultrasonic dispersion are difficult to effectively disperse highly viscous materials, and the dispersion time is relatively long, resulting in poor timeliness. Summary of the Invention

[0003] To address the problem of uniformly dispersing highly viscous materials in a short time, this invention provides a material mixing and dispersing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A material mixing and dispersing device includes a raw material tank, a screw conveyor, a dispersion liquid tank, a mixing tank, and a stirring device. The screw conveyor is disposed in the raw material tank. The outlet of the raw material tank and the outlet of the dispersion liquid tank are both connected to the inlet of a high-speed mixing pump located below the raw material tank. The outlet of the high-speed mixing pump is connected to the mixing tank located below it. The stirring device is disposed in the mixing tank.

[0005] Furthermore, the screw conveyor includes a first motor and a screw rod, one end of which is fixedly connected to the output shaft of the first motor, and the other end is vertically inserted into the raw material tank.

[0006] Furthermore, a dispersion delivery pump is installed on the connecting pipe I between the dispersion tank and the high-speed mixing pump.

[0007] Furthermore, a turbulence inlet is provided at the connection between the high-speed mixing pump and the mixing tank. The turbulence inlet includes an outer baffle and an inner baffle. The inner baffle is an annular outward-turning baffle, and the outer baffle is an annular inward-turning baffle. Both the outer and inner baffles are fixedly sleeved on the inlet pipe of the mixing tank, with the outer baffle sleeved outside the inner baffle.

[0008] Furthermore, a mixture delivery pump is installed on the connecting pipe II between the high-speed mixing pump and the mixing tank.

[0009] Furthermore, the stirring device includes a second motor and a stirring paddle, the stirring paddle being rotatably installed inside the stirring tank, and the central rod of the stirring paddle being fixedly connected to the output shaft of the second motor.

[0010] Furthermore, a liquid level detection device and an exhaust pipe are installed on the top of the mixing tank; an ultrasonic generator is installed on the bottom of the mixing tank.

[0011] Furthermore, the bottom of the mixing tank is connected to subsequent equipment via a material conveying pump.

[0012] Furthermore, a drain pipe is provided at the bottom of the mixing tank.

[0013] Furthermore, the mixing tank is fixedly mounted on the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention successfully solves the problem of uniformly dispersing highly viscous materials in a short time. The high-speed mixing pump effectively mixes viscous materials with the dispersion and reduces the viscosity of the mixture, which is beneficial for subsequent transport by the mixing pump. The mixing pump not only increases the transport speed of the mixture but also enhances the mixing effect of the subsequent turbulent inlet. The turbulent inlet can quickly change the flow direction of the material, further increasing the mixing effect and preventing the material from directly impacting the mixing tank.
