Embodiment 1

[0136] A service node for monitoring a crushing chamber comprising:

[0137] The calculation device is used to calculate the change characteristics of the feedback signal of each detection node at different positions in the crushing cavity, and has the characteristics according to the relationship between the change characteristics of the feedback signal and the preset monitoring conditions and the characteristics of the feedback signal and the distance between adjacent detection nodes. The function of judging whether the crushing cavity is worn by the formed local characteristics of the cavity shape, selectively outputting a driving signal to each detection node, and receiving a feedback signal having the cavity shape characteristic of the crushing cavity of each detection node.

[0138] A detection node for monitoring a crushing cavity, comprising: a transmitter that receives a ranging signal transmitted by a service node, generates a ranging pulse from the ranging signal, an...

Abstract

The embodimentof the invention provides an abrasion monitoring method for a crushing cavity, and belongs to the technical field of monitoring of the operating state of crushing equipment. The abrasionmonitoring method for the crushing cavity comprises the steps that feedback signals having cavity characteristics of the crushing cavity and acquired on all detection nodes located at different positions of the crushing cavity are acquired, and the next step is conducted when the feedback signal meets a first preset monitoring condition; the current detection node is selected, local cavity characteristics of the crushing cavity are determined according to intra-node characteristics between the current detection node and the adjacent detection node, the feedback signal of the current detectionnode and the feedback signal of the adjacent detection node; and when the local cavity characteristics meet a second preset monitoring condition, the second step is conducted again, so that a cyclicmonitoring process is formed. According to the abrasion monitoring method for the crushing cavity, the abrasion condition of a lining plate and the structural shape changes of the crushing cavity aremonitored according to the characteristics at detection points and the local characteristics of the current detection position, the working life of the lining plate can be predicted, and conditions are created for reasonable planning of operation and maintenance of a crushing machine.

Description

technical field [0001] The invention relates to the technical field of crushing equipment operation status monitoring, in particular to a crushing cavity wear monitoring method and a monitoring structure thereof. Background technique [0002] The working mechanism of the crusher is composed of a fixed liner and a movable liner, and the area between the working surfaces is the crushing chamber. During the crushing process, the movable liner swings according to a certain rule relative to the fixed liner to crush the material in the crushing cavity, making the particle size of the material continuously smaller until it is discharged out of the crushing cavity. [0003] During the crushing process, the materials in the crushing cavity will wear the fixed liner and the movable liner, and this wear will change the shape of the crushing cavity, resulting in the deterioration of the crushed product quality. There are two main methods for evaluating the amount of liner wear and its ...
