[0027] like Figure 1 and Figure 2 As shown, the insert-plate filter mechanism includes a rectangular frame and a filter support plate, such as... Figure 6 As shown, an outer frame is installed inside the rectangular frame. In this embodiment, the outer frame consists of several stainless steel strips, with both ends of the stainless steel strips welded to the rectangular frame. Alternatively, the outer frame can have a rectangular border, with the stainless steel strips welded to the border, and then the border welded to the rectangular frame. In this embodiment, the front edge of the filter support plate has a skirt, which is connected to the back of the rectangular frame. Figure 2 and Figure 4As shown, a filter screen is laid flat on the filter support plate. The filter screen has a corrugated cross-section. An inlet hole is provided on the filter support plate. Preferably, the inlet hole on the filter support plate matches the rectangular frame of the rectangular frame. That is, on the front projection surface, the rectangular frame and the inlet hole completely overlap. In this embodiment, for the corrugated filter screen, a stainless steel plate is first laser-drilled to form a flat filter screen, and then folded to form a corrugated filter screen. Therefore, compared to a flat filter screen, the corrugated filter screen has a larger filtration area, is more impact-resistant, has lower flow resistance, and can effectively block harmful particles in the return oil, ensuring they do not enter the oil tank. Furthermore, the corrugated filter screen is less prone to wire breakage, thus ensuring the reliability of subsequent oil use. In this embodiment, after the filter support plate is installed, a limiting groove is formed between the filter support plate and the rectangular frame. Figure 3 As shown, the edge of the filter screen is located within the limiting groove, and the front crest of the filter screen is connected to the outer frame. During installation, the corrugated filter screen is first laid on the filter screen support plate, and the edge of the filter screen is welded to the edge of the filter screen support plate. Preferably, after the filter screen is installed, the front crest of the filter screen is flush with the skirt edge on the filter screen support plate, and then the skirt edge is welded to the back of the rectangular frame, thereby ensuring the stability of the filter screen installation. Furthermore, the front crest of the filter screen corresponds to a stainless steel strip of the outer frame, and then the filter screen is strip welded or spot welded to the corresponding stainless steel strip, further ensuring the stability of the filter screen installation.
[0028] In this embodiment, as Figure 5 As shown, a collection box is also installed at the bottom of the back of the rectangular frame. The collection box has an upward-opening collection groove. Impurities after oil filtration are blocked behind the filter screen and fall into the collection box. Furthermore, as... Figure 7 As shown, the bottom of the collection box has several waist-shaped holes, and a filter plate is fixedly installed in the waist-shaped holes. The oil in the collection box can pass through the mesh on the filter plate, while impurities cannot pass through the filter plate. Therefore, when the filter mechanism is pulled out, the oil in the collection box will not be carried out, while the impurities in the collection box will be carried out, which makes it easier to clean.
[0029] In this embodiment, as Figure 1 and Figure 5As shown, two spaced stainless steel pipes are installed in the collection tank, extending upwards. The top of each stainless steel pipe protrudes from the top of the rectangular frame in the front projection direction. Magnetic rods are inserted inside the stainless steel pipes. When oil passes through the filtration mechanism, the magnetic rods generate magnetic force, attracting magnetic impurities to the surface of the stainless steel pipes. After the mechanism is removed, the magnetic rods are taken out, and the deposits on the surface of the stainless steel pipes lose their magnetism and can be easily cleaned. During cleaning, the dirt on the filtration mechanism can be blown away with compressed air or a water gun, wiped clean with a silk cloth, and then packaged.
[0030] In this embodiment, as Figure 1 As shown, the two stainless steel pipes are connected by several connecting pipes, which are spaced apart in the vertical direction. Furthermore, the tops of the two stainless steel pipes are connected by connecting rods, thus ensuring the reliability of the installation of the two stainless steel pipes. The stainless steel pipes are connected to the collection tank by welding.
[0031] In this embodiment, as Figure 1 As shown, a handle is installed on the top of the rectangular frame, allowing the operator to easily pull the filter mechanism out of the oil tank.
[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
