Abstract
Description
Technical Field
[0001] The utility model discloses a continuous stirring device, which is particularly suitable for continuous stirring and slurrying of high-fluidity grouting materials and specifically relates to the technical field of construction tools. Background Art
[0002] Conventional mixers have a single function. Low-speed mixers are suitable for mixing mortar or concrete with good workability. Low-viscosity and high-fluidity grouting materials usually require high-speed mixing equipment. However, commonly used high-speed mixing equipment has low mixing efficiency and requires a lot of manual assistance. The cylinder wall and bottom cannot be fully mixed, and the material is easy to splash out, or the cover needs to be opened repeatedly during use. In addition, there are many dead corners and residues inside the mixer, making operation and cleaning extremely inconvenient.
[0003] The continuous mixers commonly found on the market have a long stirring distance and the powder particles cannot be fully dispersed. Therefore, it is necessary to propose a continuous stirring device suitable for high-fluidity grouting materials. Summary of the Invention
[0004] In view of the deficiencies in the prior art, the utility model provides a continuous stirring device dedicated to grouting materials, which simplifies the stirring process, reduces manpower consumption, and improves stirring efficiency and quality.
[0005] In order to achieve the above-mentioned purpose, the utility model provides a continuous mixing device for grouting materials, including a motor, a reducer, a transmission stirring shaft, a stirring barrel, a stirring module, and a fixing module. The stirring barrel is provided with a feed port, a water inlet, a discharge port and an inspection port.
[0006] The transmission stirring shaft is provided with convex latches at intervals for fixing the stirring module.
[0007] The stirring module consists of a sleeve and a stirring blade. The stirring blade is welded to the sleeve. A concave slot and a fastening screw are provided inside the sleeve. During installation, the stirring module is put on the convex pin of the stirring shaft one by one through the concave slot and fastened with a fastening screw.
[0008] The fixed module consists of a liner and fixed blades. The liner is a large-diameter thick-walled steel pipe with an outer diameter slightly smaller than the inner diameter of the mixing barrel. The liner is embedded in the inner wall of the mixing barrel and fixed by fixing bolts. The fixed blades are welded to the inner wall of the liner.
[0009] Preferably, the fixing module is arranged in the middle of the mixing barrel and is arranged crosswise with the mixing module.
[0010] Preferably, the mixing barrel is a large-diameter seamless thick-walled steel pipe.
[0011] Preferably, the stirring blade located at the rear end of the transmission stirring shaft has an angle with the center line of the transmission stirring shaft that gradually decreases as it approaches the tail position, and the angle between the stirring blade on the rearmost stirring module and the center line of the transmission stirring shaft is zero.
[0012] Preferably, each stirring module is provided with 3 to 4 stirring blades, and each fixed module is provided with 3 to 4 fixed blades.
[0013] The continuous stirring equipment can be divided into three levels according to the stirring function. The first level is the front end of the stirring barrel, which is mainly used for conveying and supplemented by stirring; the second level is located in the middle of the stirring barrel, which mainly plays the role of rapid stirring; the third level is mainly used to convey the slurry that has been stirred evenly.
[0014] Before construction, the feed port on the mixing barrel is connected to a screw conveyor through a flange to transport powder materials to the mixing barrel. The water inlet is connected to a liquid metering and conveying device with adjustable flow rate, and the discharge port is connected to a slurry storage bin. The storage bin should preferably have a slow stirring function.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] First, through the two-way design of the mixing module and the fixed module, the continuous mixing equipment has the effect of shearing, kneading and mutual squeezing on the cement slurry or cement mortar material, so that the flocculent particles inside the cement slurry are fully dispersed, thereby achieving a good mixing effect. Each mixing module and fixed module are respectively provided with 3 to 4 mixing blades and 3 to 4 fixed blades, which further improves the mixing and dispersing functions. Therefore, it is very suitable for mixing high-flow or relatively high-flow cement slurry or cement mortar; second, the tail mixing blade is set with a gradual angle to improve the efficiency of continuous slurry discharge; third, there are few dead corners and residues inside the continuous mixing equipment, which is easy to clean; fourth, the number of manpower on the construction site is greatly reduced, and the construction quality and efficiency are improved.

The setting angles of the stirring blades II 10 and III 11 on the tail stirring module are different from those of the stirring blade I. When it is closer to the tail position, the angle between the stirring blade plane at the tail of the mixing barrel and the center line of the transmission stirring shaft 5 is smaller. The angle between the stirring blade III 11 on the rearmost stirring module and the center line of the transmission stirring shaft 5 is zero. The fixed module consists of a liner 8 and a fixed blade 9. The liner 8 is a large-diameter thick-walled steel pipe with an outer diameter slightly smaller than the inner diameter of the mixing barrel 4. It is embedded in the inner wall of the mixing barrel 4 and fixed by fixing bolts 12. The fixed blade 9 is welded to the inner wall of the liner 8. The fixed module is arranged in the middle of the mixing barrel 4 and is cross-arranged with the mixing module.

Connect the water inlet 14 to a liquid metering and delivery device with adjustable flow, and connect the discharge port 16 to a slurry storage bin, preferably equipped with a slow-speed mixing function.
[0025] The utility model provides a continuous mixing device for grouting materials. It can not only fully and evenly disperse high-fluidity or relatively high-fluidity cement paste or cement mortar with good mixing quality, but also achieve rapid and continuous slurry discharge, with high mixing and slurry production efficiency. Furthermore, the utility model is easy to operate, requiring only one or two people to complete the entire slurry production process. The device also has few dead corners and residues inside, making it easy to maintain and clean.
