Description

Technical Field

[0001] This utility model relates to the field of urban direct drinking water purification technology, specifically to a multi-layer filtration purification device for urban direct drinking water. Background Technology

[0002] Urban direct drinking water multi-filtration equipment is a terminal water purification device designed to solve problems such as secondary pollution and water quality fluctuations in urban tap water. Through multi-layer physical filtration and deep purification structure, it treats tap water that meets municipal standards into safe drinking water that can be drunk directly. It is widely used in public places such as communities, schools, commercial complexes and homes. The equipment does not rely on complex intelligent systems and achieves purification through pure physical filtration, providing urban residents with a safe drinking water solution that can be drunk immediately, and helping to improve the level of public drinking water hygiene. However, existing purification equipment has certain defects.

[0003] For example, a filtration device for direct drinking water in buildings, as described in application number CN202320692247.9, includes a base, a support frame, and a building wall. The base is installed on the building wall, and the support frame is fixedly installed on the upper end of the base. It also includes a filter element replacement auxiliary component for facilitating filter element replacement. This component is installed on the support frame and includes a support rod and a mounting clip. The support rod is installed on the side of the mounting clip and rotatably mounted inside the support frame. The advantage of this invention is that when replacing the filter element, by adjusting the cylindrical direct drinking water filter in the building from a longitudinal to a transverse state, the filter element can be directly pulled out, which is more convenient and labor-saving than lifting the filter element upwards. However, this purification device suffers from problems such as easy filter residue adhesion, dead angles in filtration, short filter media lifespan, inconvenient disassembly and maintenance, high energy consumption, and is prone to water waste and high operation and maintenance costs.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a multi-layer filtration purification device for urban direct drinking water. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer filtration purification device for urban direct drinking water, comprising a frame and a quick-release filtration mechanism. The quick-release filtration mechanism is fixedly connected to the top of the frame, and the quick-release filtration mechanism includes a housing fixedly connected to the top of the frame. The housing has a slot inside, and a locking block is engaged inside the slot. Three filter elements are fixedly connected to one side of the locking block, and an extension handle is provided on the top of the three filter elements.

[0007] Preferably, a water inlet is fixedly connected to the outer surface of the housing, and a wastewater recycling mechanism is fixedly connected to the inner surface of the frame.

[0008] Preferably, the wastewater recycling mechanism includes a recycling pipe fixedly connected to the inner surface of the frame, and a valve is provided on the outer surface of the recycling pipe. A water collection tank is fixedly connected to the bottom end of the recycling pipe, and a water delivery pipe is fixedly connected to the outer surface of the water collection tank. A micro pump is fixedly connected to the outer surface of the water delivery pipe.

[0009] Preferably, a booster pump is provided on one side of the housing, and a delivery pipe is provided on one side of the booster pump.

[0010] Preferably, a filter bottle is fixedly connected to one side of the conveying pipe, and a wire clamp is fixedly connected to the outer surface of the filter bottle.

[0011] Preferably, a pressure gauge is fixedly connected to the top of the filter bottle, and a control box is fixedly connected to the top of the frame.

[0012] Preferably, a sludge collection box is fixedly connected to the bottom of the filter bottle, and an outlet is provided on one side of the filter bottle.

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

[0014] 1. This utility model, through the setting of a quick-release filter mechanism, forms the core filtration and maintenance adaptation unit of the purification equipment. In addition to the basic functions of preventing filter residue adhesion, stable locking, and convenient disassembly and assembly, it further realizes multiple values ​​such as improved working condition compatibility, guaranteed equipment operation stability, and optimized maintenance efficiency through material characteristics and structural design. It provides key support for the long-term efficient operation of the purification equipment.

A water collection tank 403 is fixedly connected to the bottom end of the recovery pipe 401, and a water delivery pipe 404 is fixedly connected to the outer surface of the water collection tank 403. A micro pump 405 is fixedly connected to the outer surface of the water delivery pipe 404. A guide slope is provided on the inner wall of the inlet 3, and the inlet 3 and the outer casing 201 are sealed by argon arc welding to prevent water leakage. The valve 402 is a food-grade ball valve with a ceramic valve core. The water delivery pipe 404 is a silicone tube. The micro pump 405 is a DC diaphragm pump, which can transport the wastewater in the water collection tank 403 to the pretreatment stage for secondary filtration, thereby improving water resource utilization.

[0024] Furthermore, a booster pump 5 is provided on one side of the outer casing 201, and a delivery pipe 6 is provided on one side of the booster pump 5.

[0026] Working Principle: When using this multi-layer filtration purification equipment for direct drinking water in the city, first check the stability of the frame 1, confirm that the outer shell 201 of the quick-release filter mechanism 2 is undamaged, the slot 202 and the block 203 are tightly engaged, the three-layer filter element 204 is installed in place, the extension handle 205 is not loose, check that the inlet 3 is unobstructed, the recovery pipe 401 of the wastewater recovery mechanism 4 is not blocked, the valve 402 is closed, the water collection tank 403 is clean, the water supply pipe 404 is securely connected, the micro pump 405 is normal, check the sealing of the booster pump 5, the delivery pipe 6, and the filter bottle 7, the cable clamp 8 is tight, the pressure gauge 9 is zeroed, and the control box 10 is powered on. Then, start the equipment for purification: turn on the booster pump 5 through the control box 10 and open the inlet 3. Raw water enters the outer shell 201 of the quick-release filter mechanism 2 through inlet 3, is filtered by the three-layer filter element 204, and is then sent to the filter bottle 7 through the delivery pipe 6. The wire clamp 8 fixes the wire to prevent it from falling off, and the pressure gauge 9 monitors the pressure of the filter bottle 7 in real time.
