Abstract
Description
Technical Field
[0001] ]The utility model relates to the technical field of fire arresting devices, specifically a metal spark arresting device. Background Art
[0002] Arc cutting, grinding wheel cutting, and grinding operations generate a lot of smoke and dust, requiring exhaust and dust removal measures at the work site. This process also generates a large amount of hot metal chips and oxides, causing sparks to fly. If these sparks enter the smoke and dust removal system through the exhaust vents at the work site, they can easily burn the system and even cause a fire. Utility Model Content
[0003] The purpose of the utility model is to provide a metal spark arrester which is simple and convenient to use and is installed at the exhaust vent of an arc cutting, grinding wheel cutting or grinding operation site to prevent the hot sparks generated during the operation from entering the exhaust duct and avoiding fire.
[0004] To achieve the above objectives, the present invention provides the following technical solution: The metal spark arrester is composed of four rows of C-shaped materials. The four rows of C-shaped materials include two rows arranged in a forward direction and two rows arranged in a reverse direction, alternating in forward and reverse directions. The metal spark arrester can be installed outside the exhaust vent of a site such as arc cutting, grinding wheel cutting, or grinding operations, covering the exhaust vent. Air can enter the exhaust vent through the gaps between the four rows of C-shaped materials, and metal dust carrying sparks is trapped outside the exhaust vent by the four rows of C-shaped materials.
[0005] The beneficial effects of the utility model are as follows:
[0006] The utility model has the advantages of simple structure, easy use, and can prevent hot sparks generated by processes such as arc cutting, grinding wheel cutting, and grinding wheel grinding from entering the exhaust pipe, thereby avoiding causing fire. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION
[0008] As attached Figure 1As shown, the metal spark arrester is composed of four rows of C-shaped materials. The four rows of C-shaped materials include two rows placed in the forward direction and two rows placed in the reverse direction, which are placed in a combination of forward and reverse directions alternately. When arc cutting, grinding wheel cutting, or grinding wheel polishing are carried out at the workplace, the smoke and dust generated first pass through the metal spark arrester before entering the exhaust vent. The flying sparks hit the C-shaped materials of the metal spark arrester and are bounced back to the workplace or directly fall to the ground, unable to enter the exhaust vent. Tests have shown that the metal spark arrester can effectively prevent the hot sparks generated by arc cutting, grinding wheel cutting, and grinding wheel polishing from entering the exhaust duct and burning the smoke exhaust and dust removal system, thereby avoiding fire.
Claims
