Problems solved by technology

[0006] The purpose of the present invention is to provide a real-time detection and analysis system for the sieving force of a sieving machine, which has the advantages of adding a sieving force detection device to detect the sieving force in real time, and can adjust the sieving force in time according to the conditions of the materials to be sieved. There is no corresponding detection device for the sieving force of the screen on the sieving machine. For the sieved materials, if the sieving force cannot be detected in real time, it cannot be adjusted in time according to the condition of the material.

Abstract

The invention discloses a screening machine screening strength real-time detection and analysis system, which comprises a vibration measurement sensor, a measurement circuit, a vibration analyzer anda display recorder; and the vibration measurement sensor is fixed on a fixed bracket of a screening machine, and a feeler lever on the vibration measurement sensor is consistent with the vibration direction of a tested screen; and the feeler lever is in contact with the surface of the tested screen by means of the elastic force of the spring, and when the tested screen vibrates, the feeler lever moves along with the tested screen. A connecting wire of the vibration measurement sensor is connected into the measuring circuit, is connected to the vibration analyzer through a measuring circuit leading-out wire and then is connected to the display recorder through a vibration analyzer leading-out wire. The system has the advantages that the screening strength detection device is additionally arranged, the screening strength is detected in real time, and the screening strength can be adjusted in time according to the screened material condition.

Description

technical field [0001] The invention relates to the technical field of screening force detection of a sieving machine, in particular to a real-time detection and analysis system for the screening force of a sieving machine. Background technique [0002] The process in which the broken material is divided into different particle sizes through one or several layers of sieve surface is called sieving. The screening machine is a vibrating screening mechanical equipment that uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide sand, gravel, crushed stone and other materials into different grades according to the particle size. The screening process of the sieving machine is generally continuous. After the sieving raw materials are fed to the screening machine, the materials smaller than the sieve size pass through the sieve holes, which are called under-sieve products; the materials larger tha...
