Description

Technical Field

[0001] The utility model relates to the technical field of iron removal filters, in particular to a filter element for a coarse separation filter for removing iron-containing impurities. Background Art

[0002] In industries such as metallurgy, petrochemical, and machinery, circulating oil supply devices are commonly used to provide lubrication for gearboxes, bearings, and slipper devices. When the lubricating oil circulates inside mechanical equipment, it will carry iron-containing impurities generated by the manufacturing process or component wear and tear of various components of the mechanical equipment. When the lubricating oil circulates back to the oil supply device, the iron-containing impurities in the lubricating oil may clog or damage the circulating oil supply device, thereby causing mechanical equipment to malfunction. Currently, a permanent magnet iron removal filter is usually installed in the common circulating oil supply device. When a liquid containing magnetic impurities flows through the filter, the magnetic substances will be adsorbed on the sleeve of the magnetic rod under the magnetic action of the strong magnetic rod, thereby effectively removing the magnetic substances to ensure the integrity of the equipment and product safety. At the same time, for large-flow liquid filtration occasions, it can operate without the need for worker maintenance and achieve unattended operation. For example, Chinese Patent CN205851103U discloses a coarse separation magnetic filter element for removing iron-containing impurities, which includes a filter element cylinder body. The upper part of the filter element cylinder body is an inlet for iron-containing impurity materials. A hanging platform is fixedly installed at the upper end of the filter element cylinder body. A bottom cylinder is installed at the bottom of the filter element cylinder body. A fixed shaft suspended in the inner cavity of the filter element cylinder body is installed on the hanging platform. Multiple groups of magnetic conduction sheet groups are fixedly installed outside the fixed shaft. The filter element cylinder body includes a cylinder body framework, and a filter net is compounded on the inner wall of the cylinder body framework. The bottom cylinder includes a bottom cylinder framework, and a filter net is compounded on the upper surface of the bottom cylinder framework. A plurality of through holes are opened on both the cylinder body framework and the bottom cylinder framework. The above patent has a simple structure. When the iron-containing impurity materials enter the filter element cylinder body, the iron-containing impurities will be adsorbed on the magnetic conduction sheets to achieve the coarse separation of the iron-containing impurities. The materials pass through the filter net to further separate other impurities, and then flow out through the through holes, improving the separation efficiency of the iron-containing impurities in the materials. However, the iron-containing impurity materials will not completely pass through the magnetic conduction sheets. Due to structural limitations, there are relatively large gaps between the magnetic conduction sheets and the filter element cylinder body. Moreover, the lubricating oil is not only relatively viscous but also has a large flow rate. The iron-containing impurities in the lubricating oil far from the magnetic conduction sheets cannot be adsorbed, resulting in insufficient filtration and affecting the filtration effect.

[0003] Therefore, it is necessary for those skilled in the art to provide a filter element for a coarse separation filter for removing iron-containing impurities, which provides a larger contact and adsorption area for relatively viscous lubricating oil and improves the adequacy and stability of adsorption. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a filter element for a coarse separation filter for removing iron-containing impurities, so as to solve the technical problem that in the prior art, the lubricating oil is relatively viscous, and the iron-containing impurities wrapped inside cannot be adsorbed, resulting in insufficient filtration and affecting the filtration effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will now be described in detail with reference to the drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present utility model in a schematic manner, so it only shows the components related to the present utility model.

[0021] Please refer to Figure 1 and Figure 2 , the present utility model provides a filter element for a rough separation filter for removing iron-containing impurities, including a housing 10. The housing 10 has a cylindrical structure with openings at both ends. Mounting brackets 11 are respectively provided at the openings at both ends of the housing 10. An installation post 13 is provided inside the housing 10. Both ends of the installation post 13 respectively penetrate through the two mounting brackets 11 and extend to the outside of the housing 10. Locking members 12 are respectively threadedly connected to both ends of the installation post 13, and the locking members 12 abut against the mounting brackets 11. The installation post 13 is coaxially arranged inside the housing 10. Preferably, the locking member 12 is a nut.

[0022] In this embodiment, the mounting bracket 11 is cross-shaped and made of a metal material. The mounting bracket 11 is detachably connected to the housing 10 by fasteners such as bolts or screws. The mounting post 13 is disposed in the middle of the mounting bracket 11 to ensure the stability of the connection.

[0023] In another embodiment, the mounting bracket 11 is linear. The mounting bracket 11 is connected to the housing 10 by snap-fitting to ensure convenient installation.

[0024] Further, please refer to Figure 3 , Figure 4 , a plurality of first magnetic conductive sheets 14 and second magnetic conductive sheets 15 are uniformly arranged in the housing 10. The first magnetic conductive sheets 14 and the second magnetic conductive sheets 15 are arranged in an alternating manner. An isolation sleeve 16 is provided between the first magnetic conductive sheets 14 and the second magnetic conductive sheets 15. The isolation sleeve 16 is used to form a flow channel 19 between two adjacent first magnetic conductive sheets 14 and second magnetic conductive sheets 15.

[0025] The first magnetic conductive sheets 14 and the second magnetic conductive sheets 15 are disk-shaped. The first magnetic conductive sheets 14 and the second magnetic conductive sheets 15 are sleeved on the mounting post 13 and coaxially arranged with the mounting post 13. The circumferential side surfaces of the first magnetic conductive sheets 14 and the second magnetic conductive sheets 15 abut against the inner wall of the housing 10.

[0026] The isolation sleeve 16 is sleeved on the mounting post 13 and its two ends respectively abut against adjacent first magnetic conductive sheets 14 and second magnetic conductive sheets 15. A first through port 17 is provided on the first magnetic conductive sheet 14 near the mounting post 13. The first through port 17 axially penetrates the wall body of the first magnetic conductive sheet 14; a second through port 18 is provided on the second magnetic conductive sheet 15 far from the mounting post 13. The second through port 18 axially penetrates the wall body of the first magnetic conductive sheet 14; the second through port 18 is farther from the mounting post 13 than the first through port 17, so that the first through port 17 and the second through port 18 are arranged in an alternating manner, and the first through port 17 and the second through port 18 are respectively communicated with the flow channel 19.

[0027] In this embodiment, an O-ring (not shown in the figure) is further sleeved on the circumferential side walls of the first magnetic conductive sheets 14 and the second magnetic conductive sheets 15. The O-ring is made of a rubber material, so as to improve the sealing effect between the first magnetic conductive sheets 14 and the second magnetic conductive sheets 15, ensure the use stability, make the flow channel 19 communicate with the first through port 17 and the second through port 18 and form a separate channel in the housing 10, ensure that the lubricating oil can only flow in the separate channel, that is, the flow channel 19, and further ensure the filtering effect and the adsorption effect.

[0028] In this embodiment, a strong magnet (not shown in the figure) is provided inside the walls of the first magnetic guide sheet 14 and the second magnetic guide sheet 15. The first magnetic guide sheet 14 and the second magnetic guide sheet 15 are made of a metal material, such as stainless steel. Under the action of the strong magnet, the first magnetic guide sheet 14 and the second magnetic guide sheet 15 also carry magnetism, and the iron-containing impurities in the lubricating oil will be adsorbed on the first magnetic guide sheet 14 and the second magnetic guide sheet 15, realizing the separation and filtration of the iron-containing impurities.

[0029] In another embodiment, the first magnetic guide sheet 14 and the second magnetic guide sheet 15 are made of a metal material, such as iron. The iron is a ferromagnetic metal material with a spontaneous magnetization phenomenon. While adsorbing the iron-containing impurities in the lubricating oil, it can further magnetize the iron-containing impurities, increasing the quantity of adsorption.

[0030] During use, the lubricating oil flows into the flow channel 19 from the first through port 17 on the first magnetic guide sheet 14, and then flows out from the second through port 18 of the second magnetic guide sheet 15 and enters another flow channel 19. By arranging multiple flow channels 19 between multiple first magnetic guide sheets 14 and second magnetic guide sheets 15, the contact area between the lubricating oil and the first magnetic guide sheet 14 and the second magnetic guide sheet 15 and the flow time of the lubricating oil in the housing 10 are increased, thereby improving the filtering and separating effect of the iron-containing impurities. At the same time, the first through port 17 and the second through port 18 formed on two adjacent first magnetic guide sheets 14 and second magnetic guide sheets 15 are also arranged in a staggered manner, further increasing the flow time of the lubricating oil in the housing 10 and ensuring the filtering and separating effect of the iron-containing impurities.

[0031] In this embodiment, the first through port 17 has an arc-shaped structure. There are multiple first through ports 17 which are evenly distributed around the axis of the first magnetic guide sheet 14 to ensure the uniformity and stability of the falling of the lubricating oil. At the same time, the second through port 18 also has an arc-shaped structure. There are multiple second through ports 18 which are evenly distributed around the axis of the second magnetic guide sheet 15, further ensuring the uniformity and stability of the falling of the lubricating oil.

[0032] In this embodiment, the thickness of the first magnetic guide sheet 14 or the second magnetic guide sheet 15 is the same as the height of the isolation sleeve 16, so that the thickness of the flow channel 19 formed between two adjacent first magnetic guide sheets 14 and second magnetic guide sheets 15 is the same as the thickness of the first magnetic guide sheet 14 or the second magnetic guide sheet 15. Furthermore, the flow channel 19 of the present utility model can maintain a proper gap. During use, the relatively viscous lubricating oil will flow in the flow channel 19 in a thinner state, so that the iron-containing impurities inside the lubricating oil can be more accurately and stably adsorbed on the first magnetic guide sheet 14 or the second magnetic guide sheet 15, thereby ensuring the sufficiency of removal and improving the filtering effect of the present utility model.

[0033] The specific operation mode of the utility model is as follows: Lubricating oil is injected from one end of the housing 10, and the lubricating oil flows into the flow channel 19 through the first through hole 17 on the first magnetic conductive sheet 14, and then flows out through the second through hole 18 of the second magnetic conductive sheet 15 and enters another flow channel 19. During the flowing process of the lubricating oil, iron-containing impurities are adsorbed by the first magnetic conductive sheet 14 and the second magnetic conductive sheet 15 to complete filtration and separation.

[0034] By arranging a plurality of flow channels 19 between a plurality of first magnetic conductive sheets 14 and second magnetic conductive sheets 15, the utility model increases the contact area between the lubricating oil and the first magnetic conductive sheet 14 and the second magnetic conductive sheet 15, as well as the flowing time of the lubricating oil in the housing 10, thereby improving the filtration and separation effect of iron-containing impurities. At the same time, the first through holes 17 and the second through holes 18 formed on two adjacent first magnetic conductive sheets 14 and second magnetic conductive sheets 15 are also arranged in a staggered manner, further increasing the flowing time of the lubricating oil in the housing 10 and ensuring the filtration and separation effect of iron-containing impurities.

Those skilled in the art know that without departing from the spirit and scope of the utility model, various changes or equivalent substitutions can be made to these features and embodiments. In addition, under the teaching of the utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the utility model.
