Pulp mixing system for pulp press

Abstract

The invention discloses a slurry manufacturing stirring system of a slurry press machine. The slurry manufacturing stirring system is applied to slurry press construction of civil engineering, is used for manufacturing different types of slurries and comprises a slurry manufacturing barrel, a slurry pump and a three-way reversing valve. The slurry pump is arranged at the bottom of the slurry manufacturing barrel and is connected with a slurry outlet of the slurry manufacturing barrel by a pipeline; the three-way reversing valve is arranged on the upper portion of the slurry manufacturing barrel and is connected with a slurry inlet of the slurry manufacturing barrel by a pipeline, and the pipeline is tangential to the wall of the slurry manufacturing barrel. The slurry manufacturing stirring system is characterized by further comprising a stirring motor and a stirrer; the stirrer is a double-sided impeller, slurry inlets are formed in the peripheries of rotary shafts at the upper end and the lower end of the double-sided impeller, and slurry outlets are formed in the periphery of the outer side edge of the middle of the double-sided impeller; the stirring motor is arranged on the central axis above the slurry manufacturing barrel and is connected with the double-sided impeller, and the double-sided impeller is arranged in the center of the slurry manufacturing barrel; the stirring motor drives the double-sided impeller to carry out internal-circle stirring after being powered on, and the slurry pump carries out external-circle stirring on slurry in the slurry manufacturing barrel.

Description

technical field [0001] The invention relates to a pulping device of a grouting machine for cement mixing, in particular discloses a pulping and mixing system of a grouting machine, which is a grouting construction operation equipment in the field of civil engineering construction. Background technique [0002] There are many processes in the field of civil engineering that require grouting operations, such as grouting for prestressed tunnels, grouting for anchor rods, and grouting for foundation treatment. The function of the pulping device of the grouting machine is to mix the water and the grouting material evenly according to the designed ratio to make the grout required for grouting. [0003] The pulping device in the prior art realizes the mixing operation of the slurry in the pulping process by a blade agitator, and has three disadvantages: one is that the stirring efficiency is not high due to the unidirectional rotation of the stirred slurry, and it takes a long time...

Problems solved by technology

[0003] The pulping device in the prior art realizes the mixing operation of the slurry in the pulping process by a blade agitator, and has three disadvantages: one is that the stirring efficiency is not high due to the unidirectional rotation of the stirred slurry, and it takes a long time to mix the slurry. The slurry is mixed well; the second is that the blade resistance is relatively large, which requires more energy consumption; the third is that the local viscosity of the slurry before mixing will cause the agitator to stall, or even burn the motor

The patent No. ZL201320008091.4 "a grouting machine" proposes a slurry mixing method using the external circulation of the slurry pump, which has the advantage of high safety, but the slurry mixing efficiency is not high enough to meet the needs of users. Require
