fig. 3 is a schematic view of the internal air duct of the present invention.

In the figure: 1. an upper opening of the slag collecting box; 2. a cover plate; 3. a slag collecting box; 4. air suction narrow slits; 5. a main air duct; 6. a single air duct; 7. an electric air valve; 8. a table body; 9. a base.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the downdraft workbench comprises a workbench body 8, a material slag collecting box 3 is fixedly mounted inside the workbench body 8, an upper opening 1 of the material slag collecting box is formed in the top end of the material slag collecting box 3, an air suction narrow slit 4 is formed in the periphery of an inner cavity of the workbench body 8, a main air duct 5 is formed in the right end of the inner cavity of the workbench body 8, a single air duct 6 is formed in the inner cavity of the workbench body 8, an electric air valve 7 is movably mounted between the main air duct 5 and the single air duct 6, a plurality of single air ducts 6 are independent, a modular structure is formed, mounting and dismounting are facilitated, and supporting force is strong.

Wherein, workstation body 8's shape is the rectangle, and equal fixed mounting has base 9 on the four corners position of workstation body 8 bottom, and base 9 can provide stable support to workstation body 8, avoids empting.

Wherein, workstation body 8 all around fixed mounting have be located the apron 2 of the outside of induced draft slot 4, apron 2 can play dirt-proof effect.

Wherein, the width of the narrow air suction slit 4 is 52mm, and the narrow air suction slit 4 with the width of 52mm can thoroughly absorb the smoke dust with high concentration.

The working principle is as follows: when the downdraft workbench is used, the air suction of each single air channel is realized by the uniform air suction through a narrow gap formed by the upper opening 1 of the material residue collecting box and the surrounding cover plates 2, and the high-speed flue gas flow with large impact force can impact the material residue collecting box 3 and then reversely impact the material residue collecting box at a slow speed. At this time, the 52mm narrow suction slit 4 around the collection box can thoroughly absorb the high concentration of the smoke dust, which proves that the downdraft dust-removing cutting table can achieve the excellent effect of absorbing the smoke dust without depending on the good coverage. Because the main air duct 5 is arranged on the side surface of each single air duct 6 and is a relatively sealed cavity, each single air duct is induced draft by the electric air valve 7, the air volume loss of the traditional sliding air duct can not occur, and the smoke absorption effect is also increased.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
