Description

Technical Field

[0001] This utility model relates to the field of filters, and more particularly to an integrated coalescing filter. Background Technology

[0002] A coalescing filter is a highly efficient and compact filtration device that integrates coalescing and filtration functions into a single structure. This uniquely designed filter effectively removes suspended particles, oil droplets, and other impurities during fluid handling, ensuring the cleanliness and purity of the fluid. Its core component uses a high-performance coalescing material that rapidly aggregates tiny oil droplets into larger droplets, facilitating subsequent filtration and separation.

[0003] A coalescing filter, as described in Chinese patent document CN202022455519.2, includes a tank, a pressure plate, a water distribution tank, and multiple vertical coalescing filter elements. The pressure plate and water distribution tank are fixedly installed inside the tank and are vertically aligned. The multiple coalescing filter elements are detachably connected between the pressure plate and the water distribution tank, and each coalescing filter element is in communication with the water distribution tank. A water pipe connected to the water distribution tank is fixedly installed on the tank. Each coalescing filter element includes two vertically aligned mounting plates and four vertical filter cylinders. The four filter cylinders are concentrically arranged, and their upper and lower ends are detachably connected to the two mounting plates, respectively. This utility model is easy to assemble and disassemble and is mainly used for oil removal from wastewater.

[0004] However, the above-mentioned patent has certain drawbacks in use. The operation steps for filter cartridge replacement and sewage discharge are cumbersome and time-consuming. Furthermore, during the sewage discharge process, the impurities and moisture remaining in the filter may affect the replacement environment of the filter element, increasing the difficulty of replacement and the risk of contamination.

[0005] To address these issues, an integrated coalescing filter is proposed. Utility Model Content

[0006] To overcome the cumbersome procedures involved in discharging wastewater from existing filter cartridges, this invention provides an integrated coalescing filter.

[0007] This utility model is achieved using the following technical solution:

[0009] The top of the turntable is provided with a filter cylinder, the bottom of the filter cylinder is provided with a mounting platform that matches the opening, and the peripheral wall of the mounting platform is provided with a mounting block that matches the L-shaped sliding groove;

[0010] The inner wall of the cavity is symmetrically provided with connecting frames, and the connecting plate is provided with a limiting groove. A movable rod is embedded in the limiting groove, and an oil scraper is installed on the movable rod that fits tightly against the outer wall of the filter cartridge.

[0011] As a preferred embodiment of this utility model, the top cover is symmetrically provided with handles, the bottom of the top cover is provided with a connecting shaft, the end of the connecting shaft is provided with a bushing, the bottom of the bushing is provided with a connecting plate, the connecting plate is provided with a plurality of first bolts, and the connecting plate is connected to the top of the filter cartridge through the first bolts.

[0012] As a preferred embodiment of this utility model, an inlet valve pipe is provided on one side of the tank body, and an outlet valve pipe is provided on the side of the tank body away from the inlet valve pipe.

[0013] As a preferred embodiment of this utility model, the top cover and the top of the tank are provided with multiple connection holes, and each of the multiple connection holes is provided with a second bolt for detachably connecting the top cover and the tank.

[0014] As a preferred embodiment of this utility model, adjusting nuts for adjusting the moving position of the moving rod are symmetrically arranged at both ends of the moving rod.

[0015] As a preferred embodiment of this utility model, the outer peripheral wall of the filter cartridge is provided with multiple filter holes.

[0016] As a preferred embodiment of this utility model, multiple oil-absorbing rubber layers are provided at the point where the surface of the oil scraper is in close contact with the outer wall of the filter cartridge.

[0017] As a preferred embodiment of this utility model, the bottom of the tank is provided with multiple support legs.

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] 1. By having a turntable on the rotating shaft, the filter cartridge can be quickly loaded and unloaded by mounting blocks on the bottom mounting platform and L-shaped sliding grooves. When the equipment needs cleaning, the filter holes block the small oil particles on the outer wall of the filter cartridge. The drive motor drives the rotating shaft to rotate the turntable slightly, and the oil scraper sticks to the outer wall of the filter cartridge to scrape the oil off the surface of the filter cartridge. This makes cleaning and separation a single process, eliminating the need to frequently remove the filter cartridge for cleaning.

[0020] 2. When installing the filter cartridge, first fix the filter cartridge to the connecting plate, then align the mounting platform with the opening, align the mounting block with the L-shaped groove opening, and then gently push the filter cartridge until the mounting block is fully embedded in the L-shaped groove for easy disassembly and installation.

[0021] 3. Adjusting nuts are symmetrically installed at both ends of the movable rod. The position of the movable rod in the limiting groove can be adjusted by adjusting the nuts to ensure that the oil scraper is in close contact with the outer wall of the filter cartridge. It can also adapt to filter cartridges of different sizes and improve the oil scraping effect. Attached Figure Description
