Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1, 2, and 5, the welding fume purifier body 1 includes a fan chamber 2 and a filter device 3. The filtering device 3 comprises a filter screen layer 5, an activated carbon layer 6, a HEPA filter layer 7 and a card way support 4. The filter screen layer 5 comprises a filter screen frame 5-1, and a first filter screen 5-2, a second filter screen 5-3 and a third filter screen 5-4 which are overlapped from top to bottom in the filter screen frame 5-1, wherein the first filter screen 5-2, the second filter screen 5-3 and the third filter screen 5-4 are all in a zigzag shape and have 90 degrees of staggered undulation directions. Through the action of the three staggered filter screens, high-temperature large-particle impurities such as mars can be effectively blocked. Closely install first baffle 8 between filter screen layer 5 and the activated carbon layer 6, airflow outlet 11 set up in the left side of first baffle 8, closely install second baffle 9 between activated carbon layer 6 and the HEPA filter layer 7, airflow outlet 11 set up in the right side of second baffle 9, third baffle 10 is closely installed to 7 bottom end faces of HEPA filter layer, airflow outlet 11 set up in the left side of third baffle 10. Because the left and right positions of the airflow outlets of any two adjacent partition plates in the three partition plates are different, the welding fume can be promoted to transversely flow in the two adjacent partition plates, namely the welding fume is forced to fully flow in the filter screen layer 5, the activated carbon layer 6 and the HEPA filter layer 7, and the purification efficiency is greatly improved.

The filter screen frame 5-1 is rectangular and two sides thereof are respectively provided with a clamping groove 12. The baffle plate 8 is integrally rectangular and made of stainless steel, and the airflow outlet 11 is also rectangular and arranged on one side of the baffle plate.

As shown in fig. 3, the activated carbon layer 6 is integrally zigzag and is installed in a rectangular activated carbon layer frame 6-1, and two side surfaces of the activated carbon layer frame are respectively provided with a clamping groove 12. As shown in fig. 4, the HEPA filter layer 7 is installed in the rectangular HEPA filter layer frame 7-1, and two side surfaces of the HEPA filter layer frame are respectively provided with a slot 12. In the installation process of the filter layers, the clamping grooves 12 are installed in a matched mode with the clamping channel support 4, and when the filter layers are maintained or replaced, the filter layers are only required to be pulled out of the clamping channel support 4, so that the filter layer installation method is convenient and fast.

When the welding fume purifier adopting the filtering device 3 works, the welding fume is sucked into the filtering device 3 under the action of the fan in the welding fume fan chamber 2. After the welding fume passes through the three layers of filter screens in the filter screen layer 5, large particle impurities and sparks can be blocked and filtered, and then the welding fume enters the next activated carbon layer 6 through the left airflow outlet 11 on the first partition plate 8. The welding smoke flows to the right side in the active carbon layer 6, harmful fine impurities are adsorbed and purified under the action of the active carbon, and then the welding smoke flows enter the HEPA filter layer 7 through the right airflow outlet 11 on the second partition plate 9. The HEPA filter layer is a high efficiency particle air filter layer that more effectively filters welding fume. The welding fume in the HEPA filter layer 7 flows from right to left and is purified again under the action of the HEPA filter layer, and the purified welding fume reaches the standard and can be safely discharged into the atmosphere.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
