Description

Technical Field

[0001] This utility model relates to the field of filter cartridge technology, specifically to an insertable pleated filter cartridge rapid filtration system. Background Technology

[0002] Filter cartridge filtration technology is a physical purification method that uses filter media of specific materials to separate and retain impurities, particles, microorganisms, etc. in fluids (liquids or gases). It is widely used in water treatment, air purification, food and beverage, pharmaceutical and chemical industries. Its core principle is to use the pore size, adsorption capacity, or charge characteristics of the filter media to block the target pollutants in the fluid to one side of the filter cartridge, thereby achieving the purpose of purification or separation. There are various types of filter cartridges, and common materials include polypropylene (PP), activated carbon, nylon, glass fiber, ceramics, etc. Different materials are suitable for different scenarios, but existing filtration systems have certain drawbacks.

[0003] A quick-replacement filter cartridge, as described in application number CN202321855971.5, includes a bottom shell and a top cover mounted on the bottom shell. Its distinguishing feature is the inclusion of a connecting structure for mounting the bottom shell and the top cover. This connecting structure comprises several arc-shaped locking strips movably mounted on the top cover, corresponding locking holes on the top cover and bottom shell, and locking heads on the arc-shaped locking strips that mate with the locking holes. Each locking head includes a support strip on the arc-shaped locking strip and a locking block on the support strip. This utility model, through its connecting structure, facilitates the disassembly and assembly of the top cover and bottom shell, thereby simplifying the replacement of the filter cartridge within the bottom shell. The disassembly and assembly are simple, convenient, and quick. The guide slope on the top of the locking block and the rounded corners at the bottom of the locking holes on the bottom shell guide the locking block into the holes, facilitating assembly. However, this filter cartridge filtration device struggles to effectively intercept fine particles, resulting in residual impurities after filtration, affecting the filtration effect. Furthermore, the rinsing method makes it difficult for the water flow to evenly cover all parts of the filter cartridge, creating blind spots in the cleaning process.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed an insertable pleated filter cartridge rapid filtration system. Utility Model Content

[0005] The purpose of this invention is to provide an insertable pleated filter cartridge rapid filtration system to solve the problems mentioned in the background art, such as the filter cartridge filtration device being unable to effectively intercept fine particles, resulting in residual impurities after filtration, affecting the filtration effect, and the rinsing method having difficulty in evenly covering all parts of the filter cartridge with water flow, resulting in cleaning blind spots.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an insertable pleated filter cartridge rapid filtration system, comprising a housing and a filtration enhancement mechanism, wherein the filtration enhancement mechanism is provided inside the housing, and the filtration enhancement mechanism includes a fixed frame disposed inside the housing, wherein a coarse filter metal mesh is disposed inside the fixed frame, and a medium filter fiber layer is fixedly connected to the bottom of the coarse filter metal mesh, and a fine filter nanomembrane is fixedly connected to the bottom of the medium filter fiber layer.

[0007] Preferably, the top of the housing is provided with a cover plate, and a water inlet is fixedly connected to the top of the cover plate.

[0008] Preferably, a control valve is provided on one side of the water inlet, and a cleaning mechanism is fixedly connected to the inner wall of the housing.

[0009] Preferably, the cleaning mechanism includes a threaded tube fixedly connected to the inner wall of the housing, with a nozzle fixedly connected to one side of the threaded tube, an infusion port fixedly connected to one end of the threaded tube, and a water storage tank fixedly connected to one side of the infusion port.

[0010] Preferably, the bottom end of the fixed frame is fixedly connected to an expandable skeleton, and one side of the expandable skeleton is fixedly connected to an elastic support strip.

[0011] Preferably, a pull rod is fixedly connected to one side of the elastic support bar, and a water flow opening valve is provided on one side of the infusion port.

[0012] Preferably, a water outlet is fixedly connected to the center of the bottom of the shell, and support columns are fixedly connected to the four sides of the bottom of the shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of the filtration efficiency enhancement mechanism, not only achieves the step-by-step interception of impurities, but also extends the filter cartridge life through the pressure dispersion mechanism. Large particles are intercepted in the coarse filter layer, avoiding direct impact on the fine filter membrane and reducing the risk of membrane pore blockage; medium particles are processed by the middle filter layer, balancing the filtration pressure of each layer. Each layer works together to prevent the premature failure of a single filter cartridge due to overload, which greatly extends the maintenance cycle of the entire filtration system, effectively reducing the cost of use and resource consumption, and plays an important role in industrial production, drinking water purification and other scenarios.

[0015] 2. This utility model, through the setting of the cleaning mechanism, can not only efficiently remove the blockage on the surface of the filter element, but also penetrate deep into the fiber gaps and membrane pores, avoiding the cleaning blind spots of traditional single-point rinsing. The annularly wound threaded tube can be flexibly adapted to the shape of the filter element. Whether it is a cylindrical or square filter element, it can achieve 360-degree cleaning without any omissions, which greatly improves the cleaning efficiency. By activating the cleaning mechanism regularly, the filter element clogging speed can be effectively slowed down, the replacement frequency can be reduced, and the maintenance cost can be reduced. At the same time, it ensures that the filtration device continues to maintain high purification efficiency and extends the overall service life. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3As shown, an insertable pleated filter cartridge rapid filtration system includes a housing 1 and a filtration enhancement mechanism 2. The filtration enhancement mechanism 2 is located inside the housing 1 and includes a fixed frame 201 positioned inside the housing 1. A coarse filter metal mesh 202 is disposed inside the fixed frame 201, and a medium filter fiber layer 203 is fixedly connected to the bottom of the coarse filter metal mesh 202. A fine filter nanomembrane 204 is fixedly connected to the bottom of the medium filter fiber layer 203. The filter material first passes through the coarse filter metal mesh 202 to intercept large particles, then through the medium filter fiber layer 203 to filter medium-sized particles, and finally through the fine filter nanomembrane 204 to intercept tiny particles, achieving multi-layer filtration with a filtration accuracy of 0.1 micrometers, significantly improving the filtration effect. Simultaneously, the multi-layer structure disperses the impurity interception pressure, extending the overall service life of the filter cartridge.

[0023] like Figure 1 As shown, a cover plate 3 is provided at the top of the housing 1, and an inlet 4 is fixedly connected to the top of the cover plate 3. A control valve 5 is provided on one side of the inlet 4, and a cleaning mechanism 6 is fixedly connected to the inner wall of the housing 1. A sealing ring is provided at the contact position between the cover plate 3 and the housing 1 to ensure the sealing of the housing 1. The control valve 5 can control the flow rate to avoid excessive flow rate, which would affect the filtration effect, and at the same time, avoid excessive flow rate, which would affect the filtration efficiency.

[0024] Furthermore, the cleaning mechanism 6 includes a threaded tube 601 fixedly connected to the inner wall of the housing 1, and a nozzle 602 fixedly connected to one side of the threaded tube 601. An inlet 603 is fixedly connected to one end of the threaded tube 601, and a water tank 604 is fixedly connected to one side of the inlet 603. The threaded tube 601 is wrapped in a ring around the outside of the fixed frame 201, and multiple sets of nozzles 602 are evenly distributed between the fixed frame 201 and the threaded tube 601. When the water flow opening valve 10 is opened, the multiple sets of nozzles 602 perform all-round rinsing of the filter enhancement mechanism 2, effectively improving the cleaning efficiency.

[0025] Furthermore, an expandable skeleton 7 is fixedly connected to the bottom of the fixed frame 201, and an elastic support bar 8 is fixedly connected to one side of the expandable skeleton 7. A pull rod 9 is fixedly connected to one side of the elastic support bar 8, and a water flow opening valve 10 is provided on one side of the infusion port 603. The expandable skeleton 7 is an internal support structure and is folded. The elastic support bars 8 are evenly distributed on one side of the expandable skeleton 7. The pull rod 9 passes through the shell 1 and is connected to the expandable skeleton 7. When filtering raw materials with high viscosity or large particle content, the expandable skeleton 7 is expanded to avoid clogging of the filtration efficiency enhancement mechanism 2.

[0026] Furthermore, a water outlet 11 is fixedly connected to the center of the bottom of the shell 1, and support columns 12 are fixedly connected to the four sides of the bottom of the shell 1. A water flow opening valve 10 is also provided on one side of the water outlet 11 to control the drainage speed and facilitate the collection of the filtered raw materials.

[0027] Working Principle: When using this insert-type pleated filter cartridge rapid filtration system, after the components of the device are installed, the raw material to be filtered is input through the inlet 4 at the top of the cover plate 3. The control valve 5 is adjusted to control the flow rate of the raw material. After the raw material passes through the filtration enhancement mechanism 2, which consists of the coarse filter metal mesh 202, the medium filter fiber layer 203, and the fine filter nano membrane 204 inside the fixed frame 201, it is discharged through the outlet 11. Then, during the filtration process, when filtering raw materials with high viscosity or large particle content, the pull rod 9 on the outside of the housing 1 is pulled to drive the expandable skeleton 7 on one side of the elastic support bar 8, increasing the aperture to avoid clogging. Finally, when the inside of the housing 1 needs to be cleaned, the water flow opening valve 10 is opened, and the cleaning material inside the water tank 604 of the cleaning mechanism 6 enters the threaded pipe 601 through the inlet 603. The components inside the fixed frame 201 are then thoroughly cleaned through multiple sets of nozzles 602. The wastewater after cleaning is also discharged through the outlet 11, keeping the device clean and facilitating the next filtration operation. This is the working principle of the insert-type pleated filter cartridge rapid filtration system.
