Description
Technical Field
[0001] The utility model belongs to the technical field of starch slurry preparation, and particularly relates to a homogenizing spiral mixer for starch slurry preparation. Background Art
[0002] A screw conveyor mixer is a machine that uses a motor to drive the screw to rotate, and the rotating spiral blades push the material along the fixed casing to achieve material transportation. The screw conveyor can transport materials horizontally, inclined or vertically. It has the advantages of simple structure, small cross-sectional area, good sealing, easy operation and easy maintenance. It is widely used in building materials, chemical, food and other industries, and is suitable for conveying various bulk, powdery and granular materials.
[0003] The existing homogenizing spiral mixer for preparing starch slurry stirs the starch inside a homogenizing mixing box. The starch inside the homogenizing mixing box easily adheres to the inner wall of the homogenizing mixing box during stirring, and the starch has poor fluidity. The starch cannot fully contact with water molecules and easily forms agglomerates when it comes into contact with water. The inside of the agglomerates is a dry core, which makes it impossible for water molecules to fully penetrate into the starch particles to prevent the formation of dry cores, and the starch slurry cannot be further homogenized. Therefore, a homogenizing spiral mixer for preparing starch slurry is needed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a homogenizing spiral mixer for preparing starch slurry, so as to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a homogenizing spiral mixer for preparing starch slurry, comprising a workbench and a homogenizing mixing box, wherein a cleaning device is provided inside the homogenizing mixing box, wherein the cleaning device comprises a wall scraping cylinder, wherein a piston rod is slidably connected to the interior of the wall scraping cylinder, one end of the piston rod is fixedly connected to a moving rod, a top scraper is fixedly connected to the surface of the moving rod, side scrapers are fixedly connected to both sides of the top scraper, and an arc-shaped scraper ring is fixedly connected to the inner wall of the homogenizing mixing box.
[0006] By setting the above structure, by setting the reduction motor, mixing screw, scraping cylinder, piston rod, moving rod, top scraper, side scraper and arc scraper, when the starch slurry needs to be further homogenized, the reduction motor will drive the mixing screw to rotate, and the spiral ribbon of the mixing screw will stir the starch slurry so that the starch can be evenly dispersed, and the stirring of the spiral ribbon can generate a strong shear force to improve the homogenization of the starch slurry, which is conducive to the uniform dispersion of starch, and the water molecules can be fully immersed in the interior of the starch particles, and it can avoid the starch from easily agglomerating when it meets water as much as possible. The situation of dry core occurs. When starch adheres to the inner wall of the homogenizing spiral mixer prepared by starch slurry, the top scraper and the side scraper can scrape off the starch adhered to the inner wall of the homogenizing mixing box, thereby reducing the occurrence of starch sticking to the wall and compacting on the inner wall of the homogenizing mixing box as much as possible. At the same time, the arc scraper ring fixedly connected to the inner wall of the homogenizing mixing box will scrape off the starch adhered to the surface of the moving rod during the movement of the moving rod, so that the surface of the moving rod can avoid starch adhesion as much as possible, and the surface of the moving rod can be kept as clean and tidy as possible, which is convenient for the sliding of the moving rod.
[0007] As a preferred solution, a support plate is provided at the bottom of the workbench, and the bottoms of the plurality of homogenizing mixing boxes are fixedly connected to the top of the workbench.
[0008] As a preferred solution, a plurality of the homogeneous mixing boxes are provided with mixing screws inside, and a plurality of the homogeneous mixing boxes are provided with delivery ports inside.
[0009] As a preferred solution, a reduction motor is provided on one side of the mixing screw, and the bottom of the reduction motor is fixedly connected to the top of the workbench.
[0010] As a preferred solution, a cleaning and drainage valve plate is provided inside the homogenizing mixing box.

[0012] As a preferred solution, a slurry feed port is provided at the top of the homogeneous mixing box, a slurry discharge port is provided at the bottom of the homogeneous mixing box, two liquid level gauges are provided at the top of the homogeneous mixing box, and a liquid level gauge is provided at the bottom of the homogeneous mixing box.
[0013] By setting a slurry feed port, a slurry discharge port and a liquid level meter, when the liquid level meter detects that the starch slurry capacity inside the homogenizing spiral mixer for preparing starch slurry reaches the upper limit liquid level, the slurry feed port will no longer receive the supply of starch slurry from the upstream equipment, while the homogenizing spiral mixer for preparing starch slurry will continue to run, and the starch slurry inside it will circulate inside the equipment, which can avoid the precipitation or wall scraping and drying of starch inside the equipment, and allow the homogenized starch slurry to flow out from the slurry discharge port.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] The utility model is provided with a reduction motor, a mixing screw, a wall scraping cylinder, a piston rod, a moving rod, a top scraper, a side scraper and an arc scraper. When the starch slurry needs to be further homogenized, the reduction motor will drive the mixing screw to rotate, and the spiral ribbon of the mixing screw will stir the starch slurry so that the starch can be evenly dispersed. The stirring of the spiral ribbon can generate a strong shearing force to improve the homogenization of the starch slurry, which is beneficial to the uniform dispersion of starch, and the water molecules can be fully immersed in the interior of the starch particles, and it can avoid the starch from easily agglomerating when it meets water as much as possible. The dry core situation occurs. When starch adheres to the inner wall of the homogenizing spiral mixer prepared by starch slurry, the top scraper and the side scraper can scrape off the starch adhered to the inner wall of the homogenizing mixing box, thereby reducing the occurrence of starch sticking to the wall and compacting on the inner wall of the homogenizing mixing box as much as possible. At the same time, the arc-shaped scraper ring fixedly connected to the inner wall of the homogenizing mixing box will scrape off the starch adhered to the surface of the moving rod during the movement of the moving rod, so that the surface of the moving rod can avoid starch adhesion as much as possible, and the surface of the moving rod can be kept as clean and tidy as possible, which is convenient for the sliding of the moving rod.
[0016] The utility model provides a slurry feed port, a slurry discharge port and a liquid level meter. When the liquid level meter detects that the starch slurry capacity inside the homogenizing spiral mixer for preparing starch slurry reaches the upper limit liquid level, the slurry feed port no longer receives the supply of starch slurry from the upstream equipment, while the homogenizing spiral mixer for preparing starch slurry continues to operate, and the starch slurry inside it circulates inside the equipment, which can avoid the precipitation or wall scraping and drying of starch inside the equipment, and allows the homogenized starch slurry to flow out from the slurry discharge port.
