Description

Technical Field

[0001] The utility model relates to the technical field of fume purification, and more particularly to a novel welding fume purifier with a suction arm. Background Art

[0002] Welding fume purifiers with suction arms use an internal high-pressure blower to create a negative pressure zone at the arm's hood opening. This negative pressure draws welding fume through the arm and into the main unit. A flame arrester at the air inlet traps welding sparks, while the fume enters the cleanroom. A high-efficiency filter traps tiny smoke and dust particles within the cleanroom. Clean air then enters the cleanroom after being filtered and purified by the filter element. It is then further adsorbed and purified by an activated carbon filter before being discharged through the air outlet.

[0003] Existing fume purifiers filter smoke through an internal filter element during use. This process can leave clogged particles on the filter element's outer surface. Excessive particles can clog the filter element, reducing airflow and filtration efficiency, impacting both efficiency and quality during continuous operation. To address this, we propose a new welding fume purifier with an extraction arm. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology, meet the actual needs, and provide a new welding fume purifier with an air suction arm to solve the technical problem that the current filter element outer surface is blocked, resulting in reduced air flow and affecting the filtration efficiency.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a new welding fume purifier with an air suction arm, comprising an assembly tube and a base, a shell being fixed in the middle of the upper end surface of the base, a negative pressure device being provided in the middle of the interior of the base, docking tubes being installed through both ends of the upper end surface of the base, and the lower ends of the docking tubes being connected to the negative pressure device, assembly grooves being provided on both sides of the shell, docking windows being provided on the inner sides of the assembly grooves, an air suction arm pipe being provided in the middle of the upper end surface of the shell, the assembly tube being installed in the assembly groove, a filter element and a cleaning mechanism being provided in the assembly tube, a top cover being fixed on the upper end of the filter element, and the top cover being fitted with the upper end opening of the assembly tube.

[0006] When the utility model is used, the external power supply is powered, and the operator starts the device through the external control device, adjusts the outer end of the suction arm pipe to correspond to the welding position, starts the fan in the negative pressure device, and guides the welding smoke into the docking port of the assembly cylinder through the suction arm pipe and the docking window. After being filtered by the filter element, the gas is guided to the negative pressure device through the docking pipe and discharged from the exhaust window outside the negative pressure device. The top cover is manually rotated, and the top cover drives the filter element to rotate, and the particulate impurities on the surface of the filter element are scraped off by the scraper, so that the particles and impurities fall into the bottom of the assembly cylinder for storage. By scraping off the particulate impurities on the surface of the filter element, blockage is avoided to affect the air flow rate, and the filtration efficiency is ensured. During the assembly process, the filter element is inserted into the inner side of the cleaning mechanism, and then the outer ring of the outside is rotated. The rotation of the outer ring causes the inner meshing mouth to mesh with the meshing end of the upper end rotating shaft of the driving scraper, driving the scraper to deflect, so that the outer side of the scraper is in contact with the outer wall of the filter element. Through the above operation, the scraping part of the scraper is more closely fitted with the outer wall of the filter element, ensuring the scraping quality during the cleaning process.

[0007] Preferably, a docking port is provided on the inner side of the assembly tube, and the docking port is connected to the docking window; a bottom hole is provided on the bottom of the assembly tube, and the bottom hole is docked with the docking tube.

[0008] Preferably, limiting strips are fixed on both sides of the inner bottom end of the assembly cylinder, and the bottom of the cleaning mechanism is in contact with the upper side of the limiting strips.

[0009] Preferably, the cleaning mechanism consists of an upper ring and a lower ring, and a scraper is rotatably installed between the upper ring and the lower ring via a rotating shaft.

[0010] Preferably, the filter core is inserted between the upper ring and the lower ring, and the inner end of the scraper is in contact with the outer wall of the filter core.

[0011] Preferably, an outer ring is rotatably sleeved on the outer side of the upper ring, and an annular array on the inner side of the outer ring is provided with engaging openings.

[0012] Preferably, an engaging end is provided on the upper end rotation shaft of the scraper, and the engaging end is connected to the engaging opening of the outer ring.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model designs a cleaning mechanism and starts the fan in the negative pressure device, so that the welding smoke is introduced into the docking port of the assembly cylinder through the suction arm pipe and the docking window. After being filtered by the filter element, the gas is guided to the negative pressure device through the docking pipe and discharged from the exhaust window outside the negative pressure device. The top cover is manually rotated, and the top cover drives the filter element to rotate. The scraper scrapes off the particulate impurities on the surface of the filter element and makes them fall into the bottom of the assembly cylinder for storage. By scraping off the particulate impurities on the surface of the filter element, blockage affecting the air flow is avoided, thereby ensuring the filtration efficiency.

[0015] 2. The utility model also designs an outer ring. During the assembly process, the filter element is inserted into the inner side of the cleaning mechanism, and then the outer ring is rotated. The rotation of the outer ring causes the inner meshing mouth to engage with the meshing end of the upper end of the scraper shaft, driving the scraper to deflect, so that the outer side of the scraper fits the outer wall of the filter element. Through the above operation, the scraping part of the scraper improves the fit with the outer wall of the filter element, ensuring the scraping quality during the cleaning process.
