Water-mist dedusting system

Abstract

The invention discloses a water-mist dedusting system. The water-mist dedusting system comprises an electric system, a hydraulic system and a mist spraying system, wherein the electric system, the hydraulic system and the mist spraying system are connected in sequence. The hydraulic system is controlled by the electric system to change the outputted flow value according to a controlling instruction, and the water flow rate sprayed by the mist spraying system is changed according to the outputted flow value of the hydraulic system, wherein the hydraulic system comprises a first valve, the electric system is connected with the first valve, the opening degree of the first valve is changed according to the supplied current value of the electric system, so that the output flow value of the hydraulic system is changed. According to the water-mist dedusting system, the water flow rate can be adjusted according to the crushed stone quantity and the dust amount in a hole, dedusting operation is conducted accurately and conveniently, and the good dedusting effect is achieved.

Description

technical field [0001] The invention relates to the technical field of drilling machinery, in particular to a water mist dust removal system applied to a drilling machine. Background technique [0002] At present, in the process of down-the-hole rock drilling, most drilling rigs will encounter two problems when they are working: the rock ash is large when opening the hole and the hole is difficult to form, especially when the down-the-hole rock drilling is performed on the soft surface of the rock formation. , these two problems are more obvious. [0003] In order to solve the problem of large rock ash when drilling holes, the general drilling rig in the prior art will be equipped with a vacuum cleaner, but when drilling holes, in order to observe the effect of drilling holes and the working conditions of the rock drilling head, the dust collection cover of the vacuum cleaner is not used. It will be close to the surface of the rock formation, and when there is a strong airf...

AI Technical Summary

Problems solved by technology

However, when the rock formation is particularly soft, this artificial wall-fixing hole will be repeated several times, and at the work site of the mine, it is generally far away from the water source. The water is sometimes difficult for the operators, which affects the working efficiency of the drilling rig and the waste of labor

[0005] In order to solve the above problems, Chinese patent CN202417361U discloses a high-pressure water mist dust removal system for drilling rigs. The flow of water sprayed into the air by the high-pressure water mist dust removal system cannot be adjusted, resulting in inconvenient use and waste of resources

[0006] Aiming at the problem that the existing water mist dedusting system cannot achieve a good dust removal effect accurately and conveniently, it is necessary to provide a water mist dedusting system applied to drilling rigs
