Dual-motor high-speed circulation stirring intelligent pulping and pressing system

Abstract

An intelligent dual-motor high-speed circulating stirring mortar preparing and pressing system is provided with a circulating pump, and the inlet end and the outlet end of the circulating pump are communicated with a high-speed stirring mortar preparing barrel to form a circulating loop of the circulating pump and a circulating loop of the circulating pump and the high-speed stirring mortar preparing barrel. In a discharging pipeline of a mortar pressing machine, a low-speed stirring circulating pipeline communicated with a low-speed stirring mortar storing barrel is arranged, and a circulating loop of the mortar pressing machine and the low-speed stirring mortar stirring barrel is formed. A conveying pipeline at the mortar outlet of a prestress hole channel communicated with the low-speed stirring mortar storing barrel is provided with an automatic mortar water-binder ratio judging device. The intelligent dual-motor high-speed circulating stirring mortar preparing and pressing system has the advantages that the functions of automatic weighting, automatic feeding, automatic mortar preparing, automatic mortar pressing, automatic mortar pressing data storing and automatic pressure and time curve generating of an existing intelligent mortar preparing and pressing system can be achieved, the mortar preparing efficiency is higher, and the mortar preparing effect is better; damage caused by idling of the mortar pressing machine can be prevented; pipeline fractures and the mortar leaking phenomenon caused by too large pressure can be effectively avoided; whether the mortar water-binder ratio is qualified or not can be automatically judged; unqualified mortar can be automatically discharged; pipeline mortar accumulation is avoided, and washing is facilitated.

Description

technical field [0001] The invention relates to the technical field of prestressed engineering construction, in particular to a dual-motor high-speed circulation stirring intelligent grouting and grouting system. Background technique [0002] Grouting in the tunnel is one of the most important processes in the post-tensioned prestressed concrete structure. Whether the grouting is full and dense has a decisive impact on the corrosion of prestressed tendons, the loss of prestress, and the stiffness of prestressed components, and directly affects the quality of prestressed concrete. Structural security and durability. The traditional grouting method for prestressed pipelines is controlled by manual operation, which has many disadvantages: (1) manual weighing of ingredients, inaccurate control of water-binder ratio, resulting in serious bleeding; (2) uncontrollable pressure resulting in insufficient grouting; (3) Manually record data, human factors are uncontrollable and easy t...

Problems solved by technology

The inventor owns Chinese patent 201320831177.2, which discloses an intelligent pulping and grouting system, which can realize the functions of automatic automatic weighing, automatic feeding, automatic pulping, automatic grouting, automatic recording of grouting data and automatic generation of pressure time curves ; But it has the following disadvantages: 1. High-speed stirring is driven by a single motor, which requires a large motor power and large vibration during work, and sometimes the stirred slurry is not fine enough; 2. Due to the high pressure at the end of grouting, it is easy to appear Slurry leakage; 3. The grouting machine is easy to be damaged due to idling; 4. It is impossible to determine whether the slurry-water-binder ratio of the slurry outlet meets the requirements

[0004] Chinese patent 201210194412.4 discloses a prestressed grouting trolley and a circulating grouting method. The water-binder ratio tester can be used to measure the water-binder ratio, but it has the following defects: due to the water in the prestressed pipeline during the circulating grouting, the dilution The slurry is destroyed and its water-binder ratio is destroyed. These unqualified slurry cannot be eliminated, and are returned to the storage tank through a closed circuit, resulting in damage to the water-binder ratio of the entire bucket of slurry.
