Solution Overview

Problem

Existing grouting equipment cannot stir cement slurry according to its specific conditions, leading to residue accumulation and slurry waste due to inefficient stirring methods that waste energy.

Innovation Solution

An efficient and energy-saving building slurry stirring device is designed with a grouting assembly and a stirring assembly that includes a rotating post, stirring sleeve, scraping plate, and motor, along with a triggering element, transmission element, and switching element, allowing for controlled stirring and cleaning of the slurry tank to prevent solidification and waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If continuous stirring is performed to prevent slurry solidification, then the slurry remains fluid and free of solidification, but energy is wasted continuously

Engineering Contradiction:

Improveslurry fluidityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The stirring device operates periodically rather than continuously. The control system activates the stirring motor only when slurry solidification is detected or at predetermined intervals, and stops it when fluidity is maintained. This periodic operation prevents solidification while significantly reducing energy consumption compared to continuous stirring.

Inventive Principle:

Principle #19Periodic action

2Use of energy by moving object

If stirring is performed only when slurry slightly solidifies or fluidity becomes poor, then energy is conserved, but the slurry may solidify and require manual intervention

Engineering Contradiction:

Improveenergy consumptionVSAvoidoperational convenience

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The control system incorporates feedback mechanisms including sensors that detect slurry fluidity and operating parameters. Based on this feedback, the system automatically adjusts stirring operation timing and duration, enabling energy-saving operation while maintaining slurry fluidity without manual intervention.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The stirring device is designed to monitor and regulate its own operation based on slurry conditions. The control system automatically determines when stirring is needed and executes the stirring cycle without requiring external control, making the system self-regulating and energy-efficient.

Inventive Principle:

Principle #25Self-service

3Device complexity

If grouting equipment cannot stir slurry according to specific conditions, then the equipment structure remains simple, but residue accumulates and slurry is wasted

Engineering Contradiction:

Improveequipment structureVSAvoidslurry waste

Core Design Contradiction:

Device complexityVSLoss of substance

Solution Approach 1:

The stirring device performs preliminary stirring actions before grouting operations and cleaning actions after grouting operations. This ensures slurry remains fluid during grouting and prevents residue accumulation in the tank, reducing slurry waste without requiring complex additional equipment.

Inventive Principle:

Principle #10Preliminary action

AI summary

Provided is an efficient and energy-saving building slurry stirring device. The device includes a grouting assembly, which includes a base, a storage tank, a discharge pipe, a grouting pump and a control box. The storage tank is arranged at the top of the base, the discharge pipe is located at one side of the storage tank, the grouting pump is arranged on the discharge pipe, and the control box is fixed to the top of the base. When the fluidity of a grouting material in the storage tank is reduced due to solidification, the stirring assembly can stir the grouting material in the storage tank. Then, the stirring assembly stops stirring the grouting material to save energy. After the grouting is completed, an inner wall of the storage tank can be cleaned by the stirring assembly.
