Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter element technology, and in particular to a filter element for an emulsion filter. Background Technology
[0002] Emulsions are widely used in machining, metal processing, cooling and lubrication, and other fields. Their main functions are cooling, lubrication and cleaning of the processed surface. However, emulsions are easily contaminated by impurities during use, such as metal shavings, oil, and dust. These impurities can affect the performance of the emulsion, reduce processing quality, and even damage equipment. Therefore, the filtration of emulsions is crucial. Traditional emulsion filters usually use a filter element structure to filter the emulsion and remove impurities.
[0003] However, existing emulsion filters are usually fixed with bolts and other fasteners during installation, which makes the installation and disassembly process cumbersome, especially in situations where filter elements need to be replaced frequently. This results in low operating efficiency and increased maintenance costs.
[0004] To address the aforementioned issues, there is an urgent need for a new type of filter element for emulsion filters that can simplify the installation and disassembly process while ensuring filtration effectiveness and enhancing the stability of the filter element. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a filter element for emulsion filters.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A filter element for an emulsion filter includes a filter element assembly installed inside a filter cylinder. A rubber ring is embedded in the top of the filter cylinder. The filter element assembly includes a filter element body and two clamping plates, with the clamping plates integrally formed on the outer walls of both sides of the filter element body. A positioning component for positioning the filter element assembly is installed on the top of the filter cylinder. The positioning component includes a slide rod and a vertical plate. The vertical plate is welded to the outer wall of the top of the filter cylinder, and the slide rod is movably connected to the inner wall of a through hole on the surface of the vertical plate. A mounting shell is fixed to one end of the slide rod, and a spring is engaged between the outer wall of one side of the mounting shell and the outer wall of one side of the vertical plate. A limiting seat that cooperates with the clamping plates is welded to the other end of the slide rod.
[0008] As a further embodiment of this utility model: a threaded ring is welded to the outer wall of the top of the filter cylinder, and a cover plate is threadedly connected to the inner wall of the threaded ring, with an inlet assembly connected to the top of the cover plate.
[0009] As a further embodiment of this utility model: the inner wall of the top of the cover plate is integrally formed with a locking tube, the outer wall of the locking tube is welded with an annular plate, and the outer wall of the locking tube is fitted with a rubber ring.
[0010] As a further embodiment of this utility model: the liquid inlet assembly includes a first flange, a rotary joint, a second flange, and a telescopic bellows. The rotary joint is installed on the top outer wall of the cover plate, and the second flange is fixed to the top of the rotary joint. The telescopic bellows is fixed to the top of the second flange, and the first flange is fixed to the end of the telescopic bellows away from the second flange.
[0011] As a further embodiment of this utility model: a bracket is fixed at the bottom of the filter cylinder, and a T-shaped rod is movably connected to the through hole on the surface of the bracket. A spring is fixed between the inner wall of the bottom of the T-shaped rod and the outer wall of the bottom of the bracket. A lifting plate is fixed at the top of the T-shaped rod, and a rubber ring is glued to the bottom of the lifting plate. A retaining ring adapted to the filter element body is welded to the top of the lifting plate.

[0013] As a further improvement of this utility model: the side wall of the filter cylinder is fixed with a drain pipe by welding, and the drain pipe is connected to the internal cavity of the filter cylinder.
[0014] As a further improvement of this utility model, the outer wall of the filter cylinder is welded with support legs.
[0015] Compared with the prior art, the present invention provides a filter element for an emulsion filter, which has the following beneficial effects:
[0016] 1. By setting up a positioning component and spring one, the installation and disassembly of the filter element body becomes more convenient. During installation, simply insert the filter element body into the top insertion hole of the filter cartridge, and the clamping plate and the limiting seat will automatically engage to ensure the stability of the filter element assembly. During disassembly, simply pull the mounting shell, the limiting seat will disengage from the clamping plate, and the rebound force of spring one will lift the filter element body for easy removal.
[0017] 2. By setting rubber ring one and rubber ring three, the sealing performance between the filter element body and the filter cartridge is significantly improved. Rubber ring one forms an effective seal between the top of the filter element body and the filter cartridge to prevent emulsion leakage, while rubber ring three provides an additional seal between the annular plate and the filter element body to ensure that the emulsion does not leak from the top during the filtration process.
[0018] 3. By setting a rotary joint and a ball bearing, the telescopic bellows is effectively protected when the cover plate rotates. The rotary joint ensures that the telescopic bellows will not twist when the cover plate rotates along the threaded ring, thus avoiding damage. The ball bearing fits against the inner wall of the cover plate, reducing friction and preventing the spring from causing lateral displacement of the limit seat and slide rod due to vibration, thus ensuring the stability of the filtration process.
[0019] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Example 1
[0030] A filter element for an emulsion filter, such as Figures 1 to 7As shown, the filter cartridge assembly includes a filter element assembly installed inside the filter cartridge 1. A rubber ring 13 is embedded in the top of the filter cartridge 1, and a support leg 6 is welded to the outer wall of the filter cartridge 1. The filter element assembly includes a filter element body 10 and a clamping plate 11. The two clamping plates 11 are integrally formed on the outer walls of both sides of the filter element body 10. A positioning component for positioning the filter element assembly is installed on the top of the filter cartridge 1. The positioning component includes a slide rod 15 and a vertical plate 21. The vertical plate 21 is welded to the top outer wall of the filter cartridge 1. The slide rod 15 is slidably connected to the inner wall of the through hole opened on the surface of the vertical plate 21. A mounting shell 14 is fixed to one end of the slide rod 15. A spring 17 is engaged between the outer wall of one side of the mounting shell 14 and the outer wall of one side of the vertical plate 21. A limiting seat 12 that cooperates with the clamping plate 11 is welded to the other end of the slide rod 15.
[0031] When it is necessary to install the filter element assembly and the filter cartridge 1, first insert the filter element body 10 into the insertion hole at the top of the filter cartridge 1. When the inner wall of the top of the filter element body 10 and the rubber ring 13 are in contact with each other, the rubber ring 13 can improve the sealing effect between the filter element body 10 and the filter cartridge 1. The longitudinal section of the clamping plate 11 is a right trapezoid. When the inclined surface on the clamping plate 11 presses against the top of the limiting seat 12, the inclined surface on the clamping plate 11 is used to squeeze the limiting seat 12, so that the limiting seat 12 and the slide rod 15 slide along the vertical plate 21. When the clamping plate 11 is completely inserted into the limiting seat 12, the spring force of the spring 17 is used to make the limiting seat 12 and the clamping plate 11 complete the engagement. The limiting seat 12 positions the clamping plate 11 to ensure the stability of the filter element assembly installation.
[0032] The filter cartridge 1 has a threaded ring 5 welded to the top outer wall, and a cover plate 4 is threaded to the inner circumference of the threaded ring 5. The top of the cover plate 4 is connected to the liquid inlet assembly, and a locking tube 27 is integrally formed on the top inner wall of the cover plate 4. The outer diameter of the locking tube 27 and the inner diameter of the filter element body 10 are mutually adapted. An annular plate 25 is welded to the outer circumference of the locking tube 27, and a rubber ring 26 is sleeved on the outer circumference of the locking tube 27.
[0033] After the filter element assembly is positioned, the cover plate 4 and the threaded ring 5 are threaded together. As the cover plate 4 is rotated, the rubber ring 26 gradually moves to fit against the top outer wall of the filter element body 10. The rubber ring 26 can improve the sealing between the annular plate 25 and the filter element body 10. The emulsion to be filtered can be introduced into the positioning tube 27 using the liquid inlet assembly. After the emulsion enters the filter element body 10 through the positioning tube 27, the filter element body 10 can filter the emulsion. The filtered impurities are trapped inside the filter element body 10, and the filtered emulsion passes through the filter element body 10 and enters the chamber between the filter cartridge 1 and the filter element body 10.
[0034] The liquid inlet assembly includes flange 1 3, rotary joint 7, flange 2 8 and telescopic bellows 9. Rotary joint 7 is installed on the top outer wall of cover plate 4, flange 2 8 is fixed to the top of rotary joint 7 by bolts, telescopic bellows 9 is fixed to the top of flange 2 8, and flange 1 3 is fixed to the end of telescopic bellows 9 away from flange 2 8.
[0035] When filtering the emulsion, flange 3 is connected to the emulsion delivery pipeline (not shown). After the emulsion enters the telescopic bellows 9 through the delivery pipeline, when it is necessary to remove the cover plate 4 from the threaded ring 5, the rotary joint 7 is used to prevent the telescopic bellows 9 from twisting as the cover plate 4 rotates along the threaded ring 5, thus protecting the telescopic bellows 9.
[0036] A ball bearing 22 is movably connected inside the mounting housing 14;
[0037] When the cover plate 4 rotates along the support leg 6, the ball 22 and the inner circumference of the cover plate 4 remain in contact, thereby using the cover plate 4 to limit the limit seat 12 in the lateral direction, preventing the spring 17 from being deformed by vibration during the filtration process, which would cause the limit seat 12 and the slide rod 15 to be displaced in the lateral direction. The ball 22 and the mounting shell 14 are movably connected, reducing the friction between the ball 22 and the inner circumference of the cover plate 4.
[0038] The side wall of the filter cylinder 1 is fixed with a drain pipe 2 by welding, and the drain pipe 2 is connected to the internal cavity of the filter cylinder 1.
[0039] The filtered emulsion can be discharged by installing a drain pipe 2.
[0040] Working principle: First, insert the filter element body 10 of the filter element assembly into the insertion hole at the top of the filter cylinder 1. The inner wall of the top of the filter element body 10 fits against the rubber ring 13, which improves the sealing effect between the filter element body 10 and the filter cylinder 1. During insertion, the inclined surfaces of the retaining plates 11 on both sides of the filter element body 10 press against the top of the limiting seat 12. The inclined surface design of the retaining plates 11 causes the limiting seat 12 to be compressed and slide along the vertical plate 21 with the slide rod 15. When the retaining plates 11 are fully inserted into the limiting seat 12, the rebound force of the spring 17 makes the limiting seat 12 and the retaining plates 11 engage. The limiting seat 12 positions the retaining plates 11 in the longitudinal direction, thereby ensuring the stability of the filter element assembly installation. After the filter element assembly is positioned, the cover plate 4 is... The threaded ring 5 at the top of the filter cartridge 1 is threaded together. As the cover plate 4 rotates, the rubber ring 26 gradually fits against the outer wall of the top of the filter element body 10, improving the sealing between the annular plate 25 and the filter element body 10. The emulsion enters the telescopic bellows 9 through the conveying pipe and then flows into the locking tube 27. The emulsion enters the filter element body 10 through the locking tube 27 and is filtered by the filter element body 10. The filtered impurities are trapped inside the filter element body 10, while the filtered emulsion passes through the filter element body 10 and enters the chamber between the filter cartridge 1 and the filter element body 10. The filtered emulsion is discharged through the drain pipe 2 on the side wall of the filter cartridge 1. The drain pipe 2 is connected to the internal chamber of the filter cartridge 1, ensuring that the filtered emulsion can be discharged smoothly.
[0041] Example 2
[0042] A filter element for an emulsion filter, wherein the filter element body 10 is designed for easy removal and placement, such as... Figures 1 to 7 As shown, this embodiment makes the following additions based on embodiment 1: The bottom of the filter cylinder 1 is fixed with a bracket 18 by bolts, and a T-shaped rod 20 is slidably connected to the through hole on the surface of the bracket 18. A spring 19 is fixed between the inner wall of the bottom of the T-shaped rod 20 and the outer wall of the bottom of the bracket 18. A lifting plate 23 is fixed to the top of the T-shaped rod 20, and a rubber ring 24 is glued to the bottom of the lifting plate 23. A retaining ring 16 that matches the filter element body 10 is welded to the top of the lifting plate 23.
[0043] In the initial stage, when the spring 19 is in a normal state, the retaining ring 16 and the lifting plate 23 are located near the top insertion hole of the filter cartridge 1. When the filter body 10 is inserted into the insertion hole, the bottom of the filter body 10 moves to the top of the lifting plate 23 and remains engaged with the retaining ring 16. As the filter body 10 is pressed down, the lifting plate 23 moves down synchronously, causing the spring 19 to undergo elastic deformation and be stretched.
[0044] When it is necessary to remove the filter element assembly from the filter cartridge 1, both sets of mounting shells 14 are pulled simultaneously. After the limiting seat 12 is released from the surface of the clamping plate 11, the spring force of the spring 19 causes the lifting plate 23 to lift the filter element body 10 upward, making it easy to remove the filter element body 10 from the lifting plate 23.
[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
