Pulping and stirring system of grouting machine in civil engineering

Abstract

The invention discloses a pulping and stirring system of a grouting machine in civil engineering. The system comprises a pulping barrel, a first stirrer, a first stirring motor and a primary stirring system; a pulp caching cavity is formed in the pulping barrel; the first stirrer includes a stirring shaft for penetrating through the pulp caching cavity; the lower end of the stirring shaft is connected with a double-suction impeller; the stirring shaft is provided with multiple stirring blades with hollow structures; pulp outlet holes are formed in the stirring blades; a pulp channel for communicating with the hollow structures in the stirring blades is formed in the stirring shaft; a pulp inlet hole is formed in one part, positioned in the pulp caching cavity, of the stirring shaft; a pulp outlet for communicating with a first pulp pump is formed in the bottom of the pulping barrel; the first pulp pump communicates with an inlet end of a three-way reversing valve; one outlet end of the three-way reversing valve communicates with the pulp caching cavity; and the other outlet end communicates to a pulp storage barrel. The system fully stirs pulp by using multistage stirring and multiple stirring modes, so that prepared pulp can satisfy the application of engineering with higher quality requirements.

Description

Technical field [0001] The invention relates to a slurry making device of a slurry press for cement mixing, in particular to a slurry mixing system of a slurry press in civil engineering. Background technique [0002] There are many processes in the field of civil engineering that require grouting, such as grouting for prestressed channels, grouting for anchor rods, and grouting for foundation treatment. The function of the squeezing device of the squeezing machine is to evenly mix the water and the squeezing material according to the designed ratio to make the slurry required for squeezing. [0003] The prior art pulping device uses a blade-type agitator to realize the mixing operation of the slurry in the pulping process. Its disadvantage is: because the slurry to be stirred is a single stirring method with unidirectional rotation, the stirring efficiency is not high and it is difficult to fully mix the slurry. In particular, in engineering applications that require high-quality...

[0003] The pulping device in the prior art realizes the stirring operation of the slurry in the pulping process by a blade agitator, and its disadvantage is that the stirring efficiency is not high because the stirred slurry is a single stirring method with one-way rotation, and it is difficult to fully mix the slurry. Even, especially in engineering applications that require high-quality slurries, the existing stirring methods are difficult to meet the requirements of high-precision stirring
