Automatic screening and proportional measurement device and method of fine particles for architecture

Abstract

The invention provides an automatic screening and proportional measurement device and method of fine particles for architecture, and relates to the technical field of automatic control screening. Thedevice comprises a vibration base, a driving portion and a transmission device, a vibration frame, a screening portion, and an automatic weighing device. The vibration base comprises a bottom end horizontal frame, a spring, a vertical support rod. The driving portion and the transmission device comprise a stepping motor, a coupling, a transmission rod, a baffle, a hollow turbine, a hollow worm, and a transmission connecting part. The vibration frame and the screening portion comprise a screening net, an ultrasonic vibrator and an electric chuck. The automatic weighing device comprises a weighing disc and an electronic balance. The ultrasonic vibrator, vibration frame, the vibration and driving portion and a spring assembly are adopted, automatic screening operation of the fine particles isperformed so that fine particles with different diameters can be screened out quickly and the part of work replaces manual operation, and quick weigh and data summary are conducted, program complexity is reduced greatly and quality of screening is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of automatic control and screening, in particular to an automatic screening and ratio measurement device and method for fine particles used in construction. Background technique [0002] At present, vibrating screening devices are generally swing arm vibrating screens, suspension vibrating screens, ultrasonic vibrating screens, etc. The swinging arm vibrating screen drives the sieve to swing left and right through the swing arm to achieve vibratory screening. However, when this method is used , the overall vibration of the equipment is relatively severe, there is a large potential safety hazard, and it needs frequent maintenance and maintenance, which wastes manpower and material resources; while the cantilever sieve adopts a three-dimensional superposition structure, such a structure cannot withstand large weight screening, and the screening process is unstable In the end, it is also inconvenient to recycle...

Problems solved by technology

[0002] At present, vibrating screening devices are generally swing arm vibrating screens, suspension vibrating screens, ultrasonic vibrating screens, etc. The swinging arm vibrating screen drives the sieve to swing left and right through the swing arm to achieve vibratory screening. However, when this method is used , the overall vibration of the equipment is relatively severe, there is a large potential safety hazard, and it needs frequent maintenance and maintenance, which wastes manpower and material resources; while the cantilever sieve adopts a three-dimensional superposition structure, such a structure cannot withstand large weight screening, and the screening process is unstable In the end, it is not convenient to recycle the stratified matter; although the ultrasonic vibrating sieve can avoid the above shortcomings to a large extent, its cost is too expensive, which discourages many manufacturers.
