Embodiment Construction

[0016] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] Such as figure 1 As shown, the cavity of the cone crusher is a cavity formed between the dust ring 1, the dust cover 2, the main shaft 3, the cone 4, the pressure seat 5 and other components, the dust ring 1 and the dust cover 2 There is a very small gap between them to ensure the formation of airflow channels inside and outside, so that it forms a structure in which the internal air is greater than the external air.

[0018] The wind pressure intelligent control system of the positive pressure dust prevention system of the cone crusher provided by the present invention is as follows: figure 2 As shown, it includes a T-joint 6 connected to the positive pressure dust-proof air inlet of the dust cover 2. The T-joint 6 is connected to the d...

Abstract

The invention discloses an intelligent wind pressure control method for a positive pressure dustproof system of a cone crusher. The method involves an air blower provided with a speed adjusting motor, a frequency converter, a PLC, a differential pressure type pressure sensor, a pipeline for connecting the air blower with equipment, and an equipment airflow channel, wherein the PLC is connected with the differential pressure type pressure sensor and the frequency converter. According to the method, in the equipment operation process, the differential pressure type pressure sensor is used for monitoring the wind pressure in the pipeline in real time and on line, and continuously inputting analog signals into the PLC, the PLC is used for control, once the monitored analog signals do not accord with the preset wind pressure value of the PLC, the PLC sends an instruction to adjust the frequency converter, and the frequency converter controls and adjusts the rotating speed of the speed adjusting motor according to the instruction, so that the output wind pressure of the air blower is changed until the preset value is reached, dust is effectively prevented from entering an equipment cavity, lubricating oil is prevented from being polluted, and normal operation of the equipment and the service life of key parts are ensured.

Description

technical field [0001] The invention belongs to the technical field of hydraulic cone crushers, and relates to an intelligent wind pressure control method for a positive pressure dust-proof system of a hydraulic cone crusher. Background technique [0002] Crusher is a kind of crushing machinery used for raw materials in metallurgical mines, construction, building materials, water conservancy and other infrastructure industries. According to different crushing principles and output, it is divided into various models of single-cylinder and multi-cylinder hydraulic cone crushers. Widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industries. The cone crusher has a large crushing ratio, high efficiency, and low energy consumption. The particle size of the crushed product is uniform and stable. It is suitable for medium and fine crushing of various ores and rocks. [0003] When the cone crusher crushes ore or rock, the product w...
