Description
Technical Field
[0001] The utility model relates to the technical field of oil mist blocking filters, in particular to a primary and secondary efficiency two-in-one oil mist blocking filter. Background Art
[0002] Oil mist filter is an industrial environmental protection equipment, installed on machine tools, cleaning machines and other mechanical processing equipment, to absorb the oil mist in the processing chamber to purify the air, protect the health of workers and extend the service life of equipment. In developed countries such as Europe and the United States, the installation of oil mist filters has been listed as an industry regulation. Therefore, the installation of oil mist filters has become a historical trend.
[0003] For example, the utility model with application number CN202320417542.3 discloses an oil mist filter. The oil mist of the utility model device is introduced into the shell, and the oil mist is filtered by the primary filter plate and the medium filter plate, and the particles in the oil mist are blocked by the filter cover on the medium filter plate and remain in the filter cover, and the oil mist is also adsorbed on the filter cover to form oil droplets and finally fall into the oil discharge port of the shell, which solves the problem that the surface of the air vent window at the suction fan is easily attached by particles, and even particles are sucked into the fan and attached to the fan blades, resulting in a small fan air volume and insufficient suction, and finally resulting in a reduced oil mist filtering effect. However, in the actual use of the device, since the primary filter plate and the medium filter plate are in the shape of a plate, the filtering area inside the shell is consistent with the cross-section inside the shell, resulting in a relatively general overall dirt holding capacity, and therefore the need for multiple maintenance and replacement.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a primary and secondary efficiency two-in-one oil mist filter is provided. Utility Model Content
[0005] The utility model aims to provide a primary and secondary efficiency two-in-one oil mist blocking filter to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a two-in-one primary and secondary efficiency oil mist filter, comprising a base plate and a limiting component 1, a protective net 1 is arranged on the top of the base plate, and a top frame is fixed on the top of the protective net 1, an inner frame is slidably connected to the inside of the top frame, and a protective net 2 is connected to the bottom of the inner frame, and the bottom of the protective net 2 is connected to the inner plate, a glass fiber filter is arranged on the outside of the protective net 1, the limiting component 1 is arranged on the outside of the glass fiber filter, the limiting component 1 includes a fixing column and a limiting column, a fixing column is arranged on one side of the glass fiber filter, and a limiting column is arranged on the other side of the glass fiber filter, a limiting component 2 is arranged on the outside of the protective net 2, and the structure of the limiting component 2 is substantially consistent with the structure of the limiting component 1, and a non-woven filter is arranged inside the limiting component 2.
[0007] Furthermore, the length and width of the top frame are both 30 cm, and the distance between the top of the top frame and the bottom of the bottom plate is also 30 cm.
[0008] Furthermore, the fixing columns are equidistantly distributed with respect to the top of the bottom plate, and the limiting columns and the fixing columns are staggeredly distributed.
[0009] Furthermore, a replacement component 1 is provided at the upper and lower ends of the glass fiber filter, and the replacement component 1 includes a fixing plate and a connecting plate. The upper and lower ends of the fixing column are both provided with fixing plates, and a connecting plate is provided between the fixing plates.
[0010] Furthermore, the fixing plate is wavy in shape, and the fixing plates located at the upper and lower ends of the fixing column are fixedly connected to the top frame and the bottom plate respectively.
[0011] Furthermore, the replacement component 1 also includes a baffle and a magnet. Baffles are fixed to both upper and lower ends of the limiting column, and magnets are fixed to the ends of the baffle.
[0012] Furthermore, the baffle is wavy and matches the fixing plate.
[0013] Furthermore, replacement component 2 is provided at the upper and lower ends of the limiting component 2, and the structure of replacement component 2 is consistent with that of replacement component 1.
[0014] The utility model provides a primary and secondary efficiency two-in-one oil mist filter, which has the following beneficial effects:
[0015] 1. The glass fiber filter and the non-woven filter of the utility model are respectively surrounded on the outside of the protective net 1 and the protective net 2. Therefore, when the exhaust gas to be filtered enters from the inside of the top frame, there will be multiple surfaces for filtering, thereby expanding the filtering area, and the glass fiber filter will be wavy under the limit of the limit column and the fixed column, further expanding the filtering area. Similarly, the limit component 2 can also expand the filtering area of the non-woven filter, which is conducive to increasing the amount of dirt received during filtration and reducing the occurrence of blockage, thereby reducing the number of times the oil-blocking filter is maintained and replaced. In addition, the primary non-woven filter and the medium-efficiency glass fiber filter of the filter are located in the same filter, with a simple structure, which is also very convenient for disassembly and maintenance;
[0016] 2. The utility model adopts the setting of replacement component one. When the glass fiber filter needs to be replaced, it is only necessary to pull the baffle bar hard to separate the magnets between adjacent baffle bars, so that the limit column will not block the outside of the glass fiber filter, thereby facilitating the replacement of the glass fiber filter. Similarly, after the new glass fiber filter is wrapped around the outside of the fixed column, it is only necessary to reset the baffle bar, and the limit column will squeeze the glass fiber filter on the outside of the fixed column into a wavy shape. At the same time, the magnets can quickly fix the baffle bar by adsorption, and the baffle bar, the fixed plate and the connecting plate will press the edge of the glass fiber filter to reduce airflow. Similarly, the replacement component two can also be used to improve the convenience of replacing the non-woven filter. BRIEF DESCRIPTION OF THE DRAWINGS

The fixing columns 801 are equidistantly distributed about the top of the bottom plate 1, and the limiting columns 802 and the fixing columns 801 are staggered. The glass fiber filter 7 will be wavy under the limitation of the limiting columns 802 and the fixing columns 801, thereby expanding the filtering area. A limiting component 29 is provided on the outer side of the protective net 25, and the structure of the limiting component 29 is substantially consistent with the structure of the limiting component 18, and a non-woven filter 10 is provided inside the limiting component 29. The limiting component 29 can expand the filtering area of the non-woven filter 10, which is beneficial to increase the amount of dirt received during filtration and reduce the occurrence of blockage, thereby reducing the number of times the oil-blocking filter is maintained and replaced.
[0023] like Figure 3As shown, the upper and lower ends of the glass fiber filter 7 are provided with a replacement component 11, and the replacement component 11 includes a fixing plate 1101 and a connecting plate 1102. The upper and lower ends of the fixing column 801 are provided with fixing plates 1101, and a connecting plate 1102 is provided between the fixing plates 1101. The replacement component 11 also includes a baffle 1103 and a magnet 1104.

By pulling the baffles 1103 with force, the magnets 1104 between adjacent baffles 1103 can be separated, so that the limiting column 802 will not block the outer side of the glass fiber filter 7, thereby facilitating the replacement of the glass fiber filter 7.

Then, since the glass fiber filter 7 and the non-woven filter 10 are respectively surrounded by the outside of the protective net 2 and the protective net 2 5, when the exhaust gas to be filtered enters from the inside of the top frame 3, there will be multiple surfaces for filtration, thereby expanding the filtration area, and the glass fiber filter 7 will be wavy under the limitation of the limiting column 802 and the fixed column 801, further expanding the filtration area. Similarly, the limiting component 2 9 can also expand the filtration area of the non-woven filter 10, which is beneficial to increase the amount of pollution during filtration. Finally, in the maintenance When protecting, the oil mist filter is removed from the equipment. You only need to pull the baffle 1103 hard to separate the magnets 1104 between the adjacent baffles 1103, so that the limiting column 802 will not block the outside of the glass fiber filter 7, thereby facilitating the replacement of the glass fiber filter 7. After the new glass fiber filter 7 is wrapped around the outside of the fixed column 801, you only need to reset the baffle 1103, the limiting column 802 will squeeze the glass fiber filter 7 on the outside of the fixed column 801 into a wavy shape, and the magnets 1104 can quickly fix the baffle 1103 by adsorption, and the baffle 1103, the fixing plate 1101 and the connecting plate 1102 will press the edge of the glass fiber filter 7.
