Water spray dedusting system for plasma cutting machines

Abstract

The invention discloses a water spray dedusting system for plasma cutting machines. The water spray dedusting system comprises a water spray dedusting pipeline, wherein the water spray dedusting pipeline is arranged on the lower surface of a cutting platform below the machine head of a plasma cutting machine through a mounting frame; one end of the water spray dedusting pipeline is sealed and theother end of the water spray dedusting pipeline communicates with wastewater processing equipment through a pipeline; a cutting groove is formed in the cutting platform; the lower surface of the cutting groove communicates with the pipe wall of the upper end of the water spray dedusting pipeline; a plurality of water spray dedusting nozzles are arranged at the upper part of the water spray dedusting pipeline; and the center of the cutting groove corresponds to the center of the plasma cutting machine in an up-down direction. The water spray dedusting system is simple in structure and can be obtained through carrying out simple improvement on the basis of the existing plasma cutting machines, so that clean and tidy operation environment can be kept, impurities such as dust scabs and muds are not generated, dust generated in the cutting process can be timely and sufficiently wetted and then fused in water without diffusion, centralized pollution discharge is carried out so as to achievethe dedusting effect, the operation environment quality is improved and atmospheric pollution is avoided.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a water mist dust removal system for a plasma cutting machine. Background technique [0002] At present, the plasma cutting machine is a common equipment for cutting steel plates. The steel plate is placed under the head of the cutting machine, and the steel plate is cut by plasma rays. When the plasma cutting machine cuts steel plates, it will produce a large amount of iron oxide powder and smoke, which seriously pollutes the air quality of the working environment. [0003] In order to solve this major defect, the traditional dust removal methods include suction dust removal and water spray dust removal. Suction dust removal uses dust suction equipment to suck away a large amount of dust generated during the cutting process to avoid it from being scattered in the air and causing environmental pollution. However, due to the relatively large volume of steel plates cut by plasma, the measu...

Problems solved by technology

Suction dust removal uses dust suction equipment to suck away a large amount of dust generated during the cutting process to avoid it from being scattered in the air and causing environmental pollution. However, due to the relatively large volume of steel plates cut by plasma, the measure of dust absorption during the cutting process In actual operation, the effect is extremely unsatisfactory, and dust is prone to occur

Water spray dust removal is to spray water on the cutting point during the process of cutting the steel plate by the head of the plasma cutting machine, so that the dust will fall after wetting, which can effectively avoid the occurrence of dust, but the dust after contact with water is easy to adhere to the equipment , After long-term use, dust scabs are prone to appear, which affects the normal operation of the equipment and is not easy to clean
