Sand making online fineness modulus measurement device

Abstract

The invention discloses a sand making online fineness modulus measurement device. The sand making online fineness modulus measurement device comprises a box, a combined screening mechanism, a receiving disc and a control system, wherein the box is connected with the bottom of the combined screening mechanism through hinge joint, the box is provided with a rotary motor, a discharge chute and a feeding port; the receiving disc is provided with a weighing mechanism; the combined screening mechanism comprises screening discs, a vibration device, a wheel disc, a synchronous motor and a rotating shaft, several screen discs are fixed end to end to form a screening disc group, and when the screening disc group projects vertically, discharging ports of several screening discs are evenly distributedin a circumferential direction; the vibration device is arranged on the screening disc group; the synchronous motor is arranged on the wheel disc, and the synchronous motor is in transmission connection with the screening disc group through the rotating shaft; the weighing mechanism is in signal connection with the control system, the control system controls and connects the rotary motor, the vibration device and the synchronous motor. The sand making online fineness modulus measurement device provided by the invention has the advantages of automatic detection, high efficiency and saving labor.

Description

technical field [0001] The invention relates to a machine-made sand equipment for building materials, in particular to an online sand-making fineness modulus measuring device. Background technique [0002] With the development of society, concrete buildings are becoming more and more popular. Concrete is usually obtained by using cement as the cementitious material, sand and stone as the aggregate, and mixed with water (may contain admixtures and admixtures) in a certain proportion. The main materials The demand for sand is increasing year by year, and with the requirements of some special buildings, the production trend of sand is gradually developing towards refined production. In the process of refining sand, there is a key index fineness modulus. The fineness modulus is an index that characterizes the thickness and type of sand particle size used in construction. The larger the fineness modulus, the coarser the sand. The fineness modulus of sand is tested to evaluate it...

AI Technical Summary

Problems solved by technology

Existing detection methods are to sieve the sand by manpower in the laboratory, and then weigh the sand within each diameter range, and finally calculate the modulus, which takes a long time and is slow in efficiency. points, the detection is laborious, and cannot be applied to the production site
