Description

Technical Field

[0001] This utility model relates to the technical field of water pump filtration equipment, specifically a water pump filtration assembly that is easy to disassemble. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy, and is mainly used for transporting liquids. When a water pump transports liquid, it filters out impurities mixed in the water source being pumped through a filtration device. The treated water then passes through the pump before being output. However, current traditional filtration components use a single welded structure, which cannot be maintained layer by layer or replaced locally. The filter screen is mostly fixed with threads, requiring special tools and time for disassembly. Single-layer filter screen designs are prone to clogging, frequent replacements increase maintenance costs, and the lack of self-cleaning design allows impurities to accumulate on the filter screen surface, affecting filtration efficiency. Therefore, we propose a water pump filtration component that is easy to disassemble. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water pump filter assembly that is easy to disassemble, comprising a water pump body and a filter chamber connected to a pipeline, the top of the filter chamber being connected to a cover via a connecting mechanism, the cover having multiple mounting slots evenly spaced, and a filter mechanism being inserted into each mounting slot, the filter mechanism including a fixing block, an inclined mounting frame connected below the fixing block, a connecting frame being detachably connected to the bottom of the mounting frame via a quick-release assembly, and a filter screen installed inside the mounting frame, the three sets of filter screens being arranged in a front, middle, and rear configuration with their mesh diameters gradually decreasing.

[0005] In the above scheme, the connecting mechanism includes a locking block disposed at the bottom of the cover, the locking block being engaged in the connecting groove opened at the top of the filter chamber and fixed by the first connecting bolt.

[0006] In the above solution, the quick-release assembly includes a connecting block disposed at the bottom of the mounting bracket. The connecting block is inserted into a slot on the mounting bracket and fixed by a second connecting bolt.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: a water pump filter assembly that is easy to disassemble, including a water pump body 11 and a filter chamber 12 connected to a pipe 1. The top of the filter chamber 12 is connected to a cover 13 through a connecting mechanism. Multiple mounting slots 16 are equally spaced on the cover 13. Filtering mechanisms are inserted into the mounting slots 16. The filtering mechanism includes a fixing block 17. An inclined mounting frame 18 is connected below the fixing block 17. A connecting frame 19 is detachably connected to the bottom of the mounting frame 18 through a quick-release assembly. Filter screens 23 are installed in the mounting frame 18. Three sets of filter screens 23 are arranged in a front, middle, and rear manner, and their mesh diameter gradually decreases.

[0018] Pump body 11: As a power source, it drives the water flow and is connected to filter chamber 12 through pipe 1 to form a complete water circulation system.

[0019] Filter chamber 12: The core filter chamber, which adopts a split design. The top is detachably connected to the cover 13 through a connecting mechanism for easy maintenance.

[0020] Cover 13: Serves as the mounting base for the filter mechanism, with mounting groove 16 on it inserted into the filter mechanism to form a modular filter layout.

[0021] Three-stage filter design: The mesh diameter of the pre-filter, middle filter and the post-filter 23 gradually decreases (e.g., pre-filter coarse filter, middle filter medium efficiency filter, post-filter fine filter), so as to intercept impurities step by step, avoid overload and blockage of a single filter, and extend service life.

[0022] In the above solution, the connecting mechanism includes a locking block 14 located at the bottom of the cover 13. The locking block 14 engages with a connecting groove on the top of the filter chamber 12 and is fixed by a first connecting bolt 15. The locking block 14 and the connecting groove use a mortise and tenon joint to ensure quick alignment of the cover 13 and the filter chamber 12, preventing installation misalignment. Only a few bolts are needed to complete the sealing and fixing, simplifying the assembly and disassembly process. The locking structure, combined with a sealing ring (not shown, standard industry design), prevents water leakage.

[0023] In the above solution, the quick-release assembly includes a connecting block 2 located at the bottom of the mounting bracket 18. The connecting block 2 is inserted into a slot 21 on the connecting bracket 19 and fixed by a second connecting bolt 22. Each filter screen 23 forms an independent unit with the mounting bracket 18 and the connecting bracket 19. After the connecting block 2 is inserted into the slot 21, disassembly and assembly can be completed simply by tightening / loosening the second connecting bolt 22. The inclined design of the mounting bracket 18 increases the filtration area and guides the water flow to form a vortex, improving the impurity interception efficiency.

[0024] In the above scheme, the pipe 1 and the filter chamber 12 are detachably connected by a pipe fitting. The pipe fitting adopts a flange or clamp connection (common in the industry), which allows the pipe and filter chamber to be separated without tools, facilitating overall replacement or cleaning.

[0025] In the above scheme, a limiting seat 25 is provided inside the filter chamber 12, and a slot 26 is provided on the limiting seat 25, and the connecting frame 19 is correspondingly engaged in the slot 26. The slot 26 restricts the lateral displacement of the connecting frame 19 to prevent the filter screen from shifting due to water flow impact.

[0026] In the above scheme, a magnetic strip 24 is installed on the connecting frame 19, and the magnetic strip 24 is magnetically attracted to the limiting seat 25. The magnetic strip 24 further secures the connecting frame 19 through magnetic attraction, preventing loosening caused by vibration. The limiting seat 25 is made of stainless steel, and the magnetic strip 24 is a rubber-coated permanent magnet, possessing both corrosion resistance and attraction force.

[0027] In the above solution, elastic scrapers 27 are provided on both sides of the bottom of the cover 13 near the filter screen 23. When the cover 13 is removed, the elastic scrapers 27 (such as silicone material) contact the sides of the filter screen 23 to scrape off the attached impurities. The elastic design adapts to the deformation of the filter screen and avoids damage to the filter screen by hard scraping.

[0028] Working principle:

[0029] In this easily disassembled water pump filter assembly, during the normal filtration process: the water pump body 11 drives water to flow through pipe 1 into filter chamber 12, where it passes through three stages of filters 23 (pre-filter, middle filter, and post-filter) for tiered filtration.

[0030] Pre-filter: intercepts large particles (such as sand and gravel); Intermediate filter: filters medium particles (such as algae); Post-filter: intercepts tiny suspended solids (such as silt). After being intercepted by filter 23, the impurities are deposited at the bottom of filter chamber 12 and can be cleaned periodically by opening the cover 13.

[0031] Disassembly and maintenance process: Separate the pipe: Loosen the pipe joint, separate the filter chamber 12 from the water pump body 11, open the cover: Loosen the first connecting bolt 15, pull the cover 13 upward, and the locking block 14 disengages from the connecting groove;

[0032] Filter maintenance: Overall disassembly: Directly pull out the filter mechanism inserted into the mounting slot 16; Layered replacement: For the clogged layer, loosen the second connecting bolt 22, separate the mounting bracket 18 and the connecting bracket 19, and replace the filter 23 separately.

[0033] Self-cleaning trigger: During disassembly, the elastic scraper 27 automatically scrapes the surface of the filter screen 23 to remove residual impurities.

[0034] Stability Guarantee: The slot 26 of the limiting seat 25 and the magnetic strip 24 together constrain the position of the filter screen, preventing displacement caused by water flow impact. The inclined mounting bracket 18 guides the water flow to form laminar flow, reducing the direct impact of turbulence on the filter screen.

[0035] Modular plug-in connection and quick-release bolts enable "layered maintenance and partial replacement", avoiding the high maintenance cost of traditional integral structure; three-stage filter gradient filtration significantly reduces the load on a single layer; magnetic attraction and slot double fixation improve stability; elastic scraper cleans simultaneously during disassembly, reducing manual cleaning steps.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
