Problems solved by technology

The flow time of cement slurry in the V funnel is generally within 4S, and the timing error of this traditional V-shaped funnel is generally 0.5S-1S, and often requires two people to cooperate with the operation, and the opening time of the leak-proof support and the recording start time often occur. Out-of-synchronization phenomena that cause experiments to be repeated
The time recorded by the traditional V-shaped funnel cannot truly reflect the flow characteristics of the cleaned pulp, and it takes a lot of manpower

Abstract

The invention relates to a highly precise V-shaped funnel measurement apparatus of a cement paste. The apparatus comprise an electromagnetic system, a probe control system, a data transmission system, a data receiving system and a data analysis system. An electromagnetic field converter 5 controls the closure and the opening of a funnel leakage preventing support plate, an ultrasonic emitter 6 and an ultrasonic receiver 10 are respectively fixed in measuring points at two sides of the outlet of a V-shaped funnel by annular buckles 9, ultrasonic test data is transmitted to the control system 1 through an ultrasonic data line 3, the control system 1 immediately analyzes and records the data, and the flowing duration of the paste in the funnel is displayed on a display panel. The apparatus adopting the electromagnetic system and the ultrasonic system realizes fully-automatic, highly-precise and highly-efficient recording of the flow duration of the cement paste in the V-shaped funnel, and solves the problem of low timing precision of the V-shaped funnel.

Description

technical field [0001] The invention relates to a high-precision V-shaped funnel measuring device for cement paste, which is mainly used for the experimental research of testing the working characteristics of cement paste. Background technique [0002] Cement slurry is a slurry prepared from materials such as cement, pulverized coal, water and water reducing agent according to a specific ratio. Its working performance mainly includes fluidity and stability. V-shaped funnel is an important tool to measure its fluidity, and its flow time in V-shaped funnel is a key parameter to characterize fluidity. How to accurately and conveniently record cement net The flow time of the slurry in the V-shaped funnel is very necessary. The traditional method is to block the outlet of the V-shaped funnel with a simple leak-proof plate. When the cement paste is full of the V-shaped funnel, the leak-proof plate is manually opened, and the stopwatch button is pressed at the same time to judge t...
