Detailed Description

Example (b): referring to fig. 1-9, a negative pressure smoke collecting and cutting waste diversion system is arranged below a laser cutting equipment rack and comprises a negative pressure pipe longitudinally arranged and a plurality of bucket bodies tightened downwards; the upper part of each bucket body is communicated with the processing top surface of laser cutting equipment; all the bucket bodies are adjacently arranged along the length direction of the laser cutting equipment rack; the negative pressure pipe transversely penetrates into the plurality of bucket bodies continuously, one end of the negative pressure pipe is closed, and collecting holes are formed in the two sides of the negative pressure pipe, which are positioned in the bucket bodies; the hopper body is used for collecting smoke dust and cutting waste; after smoke dust and cutting waste materials are generated on the machining top surface of the laser cutting equipment, the smoke dust enters the hopper body by means of high-speed airflow accompanying laser cutting, and the cutting waste materials fall into the hopper body by self weight; meanwhile, the hopper bodies which are adjacently arranged along the length direction of the laser cutting equipment rack can cover most of the area of the laser cutting equipment rack with the collection range of the smoke dust and cutting waste materials without dead angles; the negative pressure pipe provides negative pressure suction force at the moment, and the smoke dust is collected into the negative pressure pipe through the collecting hole; each bucket body can enable smoke dust and cutting waste materials flowing downwards to have a tightening state by means of the bucket body structure; therefore, the smoke dust can enter the negative pressure pipe through the collecting hole under negative pressure more easily; the cutting waste can be concentrated in the central area below the bucket body, so that the cutting waste is convenient to clean; in this embodiment, there are 3 buckets, and there are 6 collection holes; the smoke dust is driven downwards by the high-speed airflow cut by the laser; the hopper body guides the smoke dust so that the smoke dust is collected to the collecting hole; the collecting hole collects the smoke dust by means of the negative pressure suction force of the negative pressure pipe; the cutting waste naturally slides to the center below the bucket body due to the self gravity and the guide of the bucket body, and is finally collected together; the three buckets can cover most of the area of the laser cutting equipment rack; the area that is not covered by the bucket body in this embodiment is laser cutting equipment unloading area, can not carry out laser cutting, also need not collect the smoke and dust, all cuts the waste material and carries out the water conservancy diversion.

The negative pressure smoke dust collecting and waste cutting diversion system also comprises a filter chamber with an industrial fan and a negative pressure pipeline; the filter chamber is communicated with a negative pressure pipe through a negative pressure pipeline; the filter chamber provides a negative pressure source for the negative pressure pipe; the smoke collected into the negative pressure pipe enters the filter chamber along the negative pressure pipeline for filtering, and the harm of harmful smoke is eliminated; the total amount of collected soot can be larger than what is possible with a filter chamber and a negative pressure line, which can collect soot continuously.

A filter screen is covered on the collecting hole; the filter screen is used for filtering the cutting waste from the mixture of smoke dust and the cutting waste and remaining outside the negative pressure pipe; thus, the cutting waste can be prevented from entering the negative pressure pipe; if the cutting waste enters the negative pressure pipe, the cutting waste collides with a mechanical structure of the negative pressure pipe or blocks a negative pressure air path in the negative pressure pipe; all of which can prevent the negative pressure tube from generating negative pressure suction.

The position of the collecting hole corresponds to the bottom end of the bucket body; the closer to the bottom end of the hopper body, the denser the smoke dust is tightened up by the hopper body, and the collection efficiency of the collection holes is higher; and the collecting hole at the bottom end of the bucket body has the highest collecting efficiency.

The bucket body comprises four transverse inclined plates and two longitudinal inclined plates which are inclined downwards; the four transverse inclined plates and the two longitudinal inclined plates are symmetrically arranged on two sides of the negative pressure pipe; the longitudinal inclined plate and the transverse inclined plate are adjacently arranged in a clinging manner; smoke dust and cutting waste materials transversely approach to the middle by virtue of the inclination of the transverse inclined plate in the process of flowing downwards along the transverse inclined plate; the smoke dust and the cutting waste materials are close to the middle longitudinally in the process of flowing downwards along the longitudinal inclined plate; and finally, the smoke dust and the cutting waste are collected to the center below the hopper body, so that the smoke dust is favorably sucked away by the negative pressure pipe, and the cutting waste is cleaned.

The negative pressure pipe is arranged in the middle of the laser cutting equipment rack; the collecting hole is equivalent to the negative pressure suction force at the two sides of the negative pressure pipe; the negative pressure pipe can carry out equal negative pressure suction to negative pressure pipe both sides like this, avoids making the smoke and dust effectively collected because the negative pressure suction of certain one side of negative pressure pipe is not enough.

The transverse inclined plate is tightly attached to the negative pressure pipe, so that smoke dust is prevented from overflowing and leaking between the transverse inclined plate and the negative pressure pipe; because of the blocking of the transverse inclined plate, the negative pressure pipe and the collecting hole can not ensure that the smoke dust entering the back of the transverse inclined plate can be collected.

The working process of the embodiment:

laser cutting generates smoke and cutting waste; smoke dust flows downwards by means of high-speed airflow cut by laser and then is concentrated towards the middle along a transverse inclined plate and a longitudinal inclined plate; the cutting waste material falls freely and then is concentrated towards the middle along the transverse inclined plate and the longitudinal inclined plate; the concentrated smoke dust enters the negative pressure pipe through the collecting hole; the negative pressure pipe enters the filter chamber along the negative pressure pipeline; the smoke dust is filtered by the filter chamber to eliminate the harm of harmful smoke dust; the cutting waste materials are blocked outside the negative pressure pipe by the filter screen, can only continuously slide downwards along the transverse inclined plate and the longitudinal inclined plate, and are finally concentrated in the central area below the bucket body; in this way the fumes are collected sufficiently and the cutting waste is also directed to the central area below the body.
