Description

Technical Field

[0001] This utility model relates to the chemical industry, and in particular to a mixing device for high-viscosity materials. Background Technology

[0002] For fluid materials, mixing is usually achieved by stirring. However, for high-viscosity fluid materials, traditional stirring methods are often insufficient to achieve uniform mixing. When small amounts of liquid, such as pH adjusters, need to be added, thorough mixing becomes even more difficult, requiring longer mixing times and increased energy consumption, such as electricity and heat.

[0003] Therefore, designing a device that can efficiently mix high-viscosity materials is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a mixing device for high-viscosity materials. This device has a simple structure, is easy to use, and facilitates the mixing of additives with high-viscosity materials.

[0005] The technical solution of this utility model is: a mixing device for high-viscosity materials, including a mixing vessel, an elevated tank, and a circulation pipeline. The elevated tank is located above the mixing vessel. The upstream end of the circulation pipeline is connected to the bottom of the mixing vessel, and the downstream end of the circulation pipeline is connected to the top of the mixing vessel. A circulation pump is installed on the circulation pipeline. A spiral guide strip is installed in the circulation pipeline. The outer diameter of the spiral guide strip is adapted to the inner diameter of the circulation pipeline. The elevated tank is connected to the circulation pipeline through a feed pipe. The downstream end of the feed pipe extends from the upstream end of the spiral guide strip into the internal space of the spiral guide strip.

[0006] The circulation pipeline includes a horizontal extension section, and both ends of the horizontal extension section are detachably connected to the connecting pipeline via flanges.

[0007] A limiting ring platform is provided at the downstream end of the horizontal extension section, and the spiral guide bar cooperates with the limiting ring platform to form a limit.

[0008] The feed pipe is composed of an L-shaped pipe section and a vertical pipe section. The horizontal section of the L-shaped pipe section is located in the horizontal extension section of the circulation pipe and extends into the internal space of the spiral guide bar. The vertical section passes through the horizontal extension section of the circulation pipe and is connected to the high-level tank through the vertical pipe section.

[0009] Valves are installed on the vertical pipe section.

[0010] The circulating pump is located upstream of the horizontal extension.

[0011] The above technical solution has the following beneficial effects:

[0012] 1. A mixing device for high-viscosity materials includes a stirred tank, an elevated tank, and a circulation pipeline. The stirred tank is used to stir and mix the high-viscosity material and a small amount of added liquid additives, such as pH adjusters like liquid alkali or ammonia. The elevated tank is used to hold the liquid additives. The circulation pipeline is used to circulate the high-viscosity material in the stirred tank to the external environment. The elevated tank is located above the stirred tank, meaning that the liquid additives loaded in the elevated tank can enter the stirred tank under gravity. The upstream end of the circulation pipeline is connected to the bottom of the stirred tank, and the downstream end is connected to the top of the stirred tank. A circulation pump is installed on the circulation pipeline. Under the action of the circulation pump, the high-viscosity material in the stirred tank returns from the bottom to the top of the stirred tank through the circulation pipeline. A spiral guide bar is installed in the circulation pipeline. The outer diameter of the spiral guide bar is adapted to the inner diameter of the circulation pipeline. When the circulating high-viscosity material flows through the spiral guide bar in the circulation pipeline, the high-viscosity material is rotated circumferentially by the spiral guide bar, forming a vortex-like fluid. The high-level tank is connected to the circulation pipeline through a feed pipe. The downstream end of the feed pipe extends from the upstream end of the spiral guide bar into the internal space of the spiral guide bar. The small amount of liquid additive added mixes with the vortex fluid, which can effectively ensure the mixing effect and mixing efficiency of the mixed liquid additive and the high-viscosity material, shorten the mixing time of the high-viscosity material and the liquid additive, and thus reduce the consumption of electrical energy and heat energy.

[0013] 2. The circulation pipeline includes a horizontal extension section. Both ends of the horizontal extension section are detachably connected to the connecting pipeline via flanges, facilitating the installation and disassembly of the horizontal extension section and the installation and maintenance of the spiral guide strip. A limiting ring is provided at the downstream end of the horizontal extension section. The spiral guide strip cooperates with the limiting ring to form a limiting position, ensuring the stability of the spiral guide strip within the horizontal extension section.

[0014] 3. A valve is installed on the vertical section of the feed pipe. By controlling the valve opening, the addition rate of the liquid additive is controlled, so that the liquid additive is mixed with an appropriate amount of high-viscosity material in a vortex-like fluid, ensuring the overall mixing effect.

[0015] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

Detailed Implementation

[0020] See Figures 1 to 3 This is a specific embodiment of a mixing device for high-viscosity materials. The mixing device includes a stirred tank 1, an elevated tank 2, and a circulation pipeline 3. The stirred tank is a conventional stirring device in the chemical industry, and the elevated tank is used to hold liquid additives, such as liquid alkali, ammonia, and pH adjusters. The elevated tank 2 is located above the stirred tank 1. The upstream end of the circulation pipeline 3 is connected to the bottom of the stirred tank 1, and obviously, the upstream end of the circulation pipeline is offset from the discharge port of the stirred tank. The downstream end of the circulation pipeline 3 is connected to the top of the stirred tank 1. Typically, the downstream end of the circulation pipeline is connected to the inlet of the stirred tank. In this embodiment, the circulation pipeline 3 includes a horizontal extension section 31. Both ends of the horizontal extension section 31 are detachably connected to the connecting pipeline via flanges, and a limiting ring platform 32 is provided at the downstream end of the horizontal extension section 31. A circulation pump 4 is installed on the circulation pipeline 3, and obviously, the circulation pump 4 is located upstream of the horizontal extension section. The circulation pipeline 3 is equipped with a spiral guide bar 5. The outer diameter of the spiral guide bar 5 is adapted to the inner diameter of the circulation pipeline 3. Specifically, the spiral guide bar is set in the horizontal extension section and is axially limited by a limiting ring platform. The length of the spiral guide bar is determined according to actual needs, and obviously, the length of the spiral guide bar does not exceed the length of the horizontal extension section. The high-level tank 2 is connected to the circulation pipeline 3 through a feed pipe 6. The downstream end of the feed pipe 6 extends from the upstream end of the spiral guide bar 5 into the internal space of the spiral guide bar. In this embodiment, the feed pipe 6 is composed of an L-shaped pipe section 61 and a vertical pipe section 62. The horizontal section of the L-shaped pipe section 61 is set in the horizontal extension section 31 of the circulation pipeline and extends into the internal space of the spiral guide bar 5. The vertical section exits the horizontal extension section 31 of the circulation pipeline and is connected to the high-level tank 2 through the vertical pipe section 62. A valve 7 is set on the vertical pipe section 62. The valve is a regulating valve used to control the flow rate of the liquid additive in the high-level tank.

[0021] The working principle of the present utility model is as follows: High-viscosity materials are added into the stirring kettle, and the stirring device equipped with the stirring kettle rotates to stir and mix the high-viscosity materials. Then the circulation pump is turned on, and the high-viscosity materials at the bottom of the stirring kettle flow back to the top of the stirring kettle through the circulation pipeline, forming a circulation to improve the mixing effect of the high-viscosity materials in the stirring kettle. When the high-viscosity materials flow through the horizontal extension section of the circulation pipeline, the high-viscosity materials are affected by the spiral guiding strips and rotate circumferentially to form a swirling fluid, mixing the high-viscosity materials flowing through. By controlling the opening degree of the valve, the liquid additive flows into the internal space of the spiral guiding strips and is fully mixed with the swirling fluid to ensure the mixing effect.
