Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically a heating water filter. Background Technology

[0002] In heating water systems, the presence of scale, metal particles, metal powder, and impurities can lead to pipe blockage, equipment wear, and damage to main heat exchange equipment, circulating water pumps, and sensing devices. This results in decreased heating equipment thermal efficiency, increased failure rate, and seriously affects system stability and lifespan. Traditional filters mostly use physical filter screens and magnetic components to adsorb and intercept impurities. However, an unreasonable design of the magnetic component placement can lead to limited filtration of metal particles and low adsorption efficiency. In particular, ferromagnetic impurities are prone to remain in the system and are difficult to completely remove. In addition, existing filtration devices often have problems such as complex structure and inconvenient maintenance. To address these issues, existing equipment needs to be improved.

[0022] 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.

[0023] Please see Figures 1-9This utility model provides a technical solution: a heating water filter, including a filter housing 1 and inlet / outlet connectors 5 connected to the filter housing 1. The inlet / outlet connectors 5 can be made of brass or plastic. The inlet / outlet connectors 5 are installed on one side of the filter housing 1 via a side pressure cap 4. The inlet / outlet connectors 5 are screwed onto the interface 101 via the side pressure cap 4. A filter assembly 3 is installed inside the filter housing 1, and a clean water chamber is formed between the filter assembly 3 and the interior of the filter housing 1. The internal cavity of the filter assembly 3 is a water filtration chamber, and the upper part of the filter housing 1 is provided with... The removable top cover 2 is connected to the filter housing 1 by internal threads. At the same time, the filter housing 1 is connected to the lower part of the drain valve 11, which makes the fit more secure. The filter housing 1 and the drain valve 11 are fixed by a spiral engagement structure. The lower end of the drain valve 11 is connected to the drain valve plug 12 by threads. The lower part of the top cover 2 extends into the filter assembly 3 to form an extension 201, and a water-proof magnetic rod adsorption component 15 is installed in the extension 201. At the same time, the top cover 2 is also equipped with a drain valve 14, which is connected to the top cover 2 by a threaded engagement.

[0024] The filter assembly 3 in this example includes a filter screen 301 and a filter housing 302. The filter screen 301 is fixedly connected to the bottom of the filter housing 302. The filter housing 302 and the filter screen 301 are integrated into one unit, making the filter screen 301 more stable and the filtration more comprehensive. The area inside the filter screen 301 below the filter housing 302 has an inverted conical structure. The unique inverted conical structure and the dirt-blocking inclined plate are conducive to the sedimentation and collection of impurities. The axial distribution of magnets improves the adsorption efficiency of ferromagnetic particles. At the same time, the filter housing 302 has a slot 3021. The top of the filter housing 302 has a D-shaped inner cavity design, which allows the filter chamber to have a larger flow space, resulting in better filtration flow and quality.

[0025] In this example, the filter housing 1 has an interface 101 on one side, which is connected to the inlet / outlet water connector 5. The filter housing 1 also has a locking strip 103 inside the other side, which engages with the slot 3021. This allows the filter assembly 3 to be positioned by the locking strip 103 when it is inserted into the housing. The precise positioning of the cylinder allows for seamless isolation between the filter chamber and the clean water chamber, improving the heating filtration effect.

[0026] In this example, the inlet / outlet water connector 5 is connected to the interface 101 on the left side of the filter housing 1 via the side pressure cover 4. A clamping spring 9 is provided on the right side of the inlet / outlet water connector 5, and a side cover rubber gasket 7 is installed between the inlet / outlet water connector 5 and the interface 101. The side cover rubber gasket 7 is placed at the interface 101, and the clamping spring 9 provides radial fastening force.

[0027] In this example, a cover gasket 8 is installed between the filter housing 1 and the top cover 2, and a sealing gasket 10 is provided between the filter housing 1 and the drain valve 11. The cover gasket 8 is used to fill the tiny gap between the filter housing 1 and the top cover 2 to prevent water from leaking from the joint. The drain valve 11 is a key channel for the discharge of impurities. The sealing gasket 10 can prevent leakage at the connection between the filter housing 1 and the drain valve 11, and at the same time reduce the risk of loosening caused by vibration.

[0028] The waterproof magnetic rod adsorption component 15 in this example includes a magnetic rod screw 1505, a magnetic rod magnet 1504 fitted at the bottom of the magnetic rod screw 1505, a magnetic rod pad 1503 disposed on the magnetic rod magnet 1504, and a magnetic rod magnet 1504 disposed on the magnetic rod pad 1503. A magnetic rod handle 1502 is disposed on the magnetic rod handle 1502, and a magnetic rod magnet is disposed at the top of the magnetic rod handle 1502. The magnetic rod nut 1501 and the magnetic rod screw 1505 are threadedly connected. The water-proof magnetic rod adsorption component 15 is installed in the extension 201 of the upper cover 2. The magnetic rod screw 1505 is connected in series with the magnetic rod magnet 1504, the magnetic rod washer 1503, the magnetic rod handle 1502 and the magnetic rod nut 1501. It can be axially disassembled to clean the adsorbed metal particles. The repulsive magnetic attraction design will bring a strong magnetic force on the side of the magnetic rod, making the magnetic adsorption ability better.

[0029] In this example, a hook 102 is provided on the other side of the filter housing 1, and a wrench 13 is installed on the hook 102. At the same time, a decorative ring 6 is connected to the bottom of the filter housing 1 by a buckle. The design of the hook 102 and the wrench 13 allows the user to disassemble the filter cavity at any time to clean the filter screen 301, which is convenient for installation and operation.

[0030] Working principle: When assembling this heating water filter, first, put the clamp spring 9 into the groove on the right side of the inlet / outlet connector 5, place the side cover rubber gasket 7 at the interface 101, and then fix it to the interface 101 on the left side of the filter housing 1 by the side pressure cover 4. The clamp spring 9 provides radial tightening force. Insert the filter assembly 3 into the filter housing 1, and at the same time, align the slot 3021 with the locking strip 103 to prevent the filter assembly 3 from running off-center. Install the top cover rubber gasket 8 on the upper part of the filter housing 1, and then screw on the top cover 2. Install the water-proof magnetic rod adsorption part 15 in the extension 201 of the top cover 2, and then install the drain valve 14 on the top cover 2. Install the sealing gasket 10 inside the drain valve 11, and then screw it all to the bottom of the filter housing 1. Screw the drain valve plug 12 onto the end of the drain valve 11, and then fix the decorative ring 6 to the bottom of the filter housing 1 by the buckle. Finally, install the wrench 13 on the hook 102 on the right side of the filter housing 1.

[0031] When using this heating water filter, water flows into the filter chamber through the inlet below the inlet / outlet connector 5. The water-blocking magnetic rod adsorption component 15 adsorbs some magnetic impurities in the water onto the surface of the extension 201. Large particles of impurities are then intercepted by the filter screen 301 and flow into the clean water chamber. The water in the clean water chamber is discharged through the outlet above the inlet / outlet connector 5. When air needs to be released, unscrew the vent valve 14 to release the air. After the air is released, tighten the vent valve 14 onto the top cover 2. When draining, unscrew the magnetic rod nut 1501 and remove the water-blocking magnetic rod adsorption component 15 as a whole. Open the drain valve 11, and impurities are discharged with the water flow from the drain valve plug 12. After the impurities are discharged, close the drain valve 11, clean it, and reinstall it. This completes the entire operation. Any content not described in detail in this manual is prior art known to those skilled in the art.
