Description

Technical Field

[0001] This utility model relates to the field of liquid purification equipment, specifically a pre-filter device with guide vanes. Background Technology

[0002] In the field of liquid purification equipment, pre-filters are crucial components for ensuring water quality safety, and their performance and structural design directly affect purification efficiency and equipment lifespan. While current pre-filters on the market meet basic filtration needs to a certain extent, they still face several technical challenges. An unreasonable water flow path design increases water flow resistance, affecting water throughput. Uneven water flow distribution directly impacts the filter element, shortening its lifespan. Furthermore, traditional filter materials and structural designs have limitations in filtration effectiveness, making it difficult to efficiently remove tiny impurities and particulate matter from water. Additionally, safe operation and ease of maintenance are key concerns for users. For example, the lack of effective pressure regulation mechanisms and convenient impurity discharge methods may affect equipment stability and user experience. Utility Model Content

[0003] The purpose of this invention is to provide a pre-filter device with guide vanes to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A pre-filter with guide vanes includes a head unit. A bottle-shaped outer shell is fixedly connected to the bottom of the head unit. A drainage assembly is provided at the bottom of the bottle-shaped outer shell. A water inlet is provided on one side of the head unit, and a water outlet is provided on the other side of the head unit. A guide frame is provided below the head unit. Multiple guide vanes are provided on the guide frame. A fixed shaft is provided inside the guide frame. A connecting rod is fixedly provided at the bottom of the fixed shaft. A filter element is fixedly connected to the bottom of the connecting rod. The filter element is located inside the bottle-shaped outer shell.

[0006] In a preferred embodiment, the water outlet is equipped with a pressure balancing valve, the bottle-shaped outer shell is equipped with a regulator, the regulator is connected to the drainage assembly, a first sealing ring is provided between the fixed shaft and the machine head, and a second sealing ring is provided between the flow guide frame and the filter element.

[0007] In a preferred embodiment, the filter element includes a frame and a filter screen, the filter screen is installed inside the frame, the frame has a water inlet hole on its side wall, and the filter screen is made of stainless steel.

[0008] In a preferred embodiment, the cavity inside the bottle-shaped outer shell serves as the raw water channel, and the cavity inside the guide frame serves as the water outlet channel.

[0009] In a preferred embodiment, the inlet and outlet are equipped with built-in rotating flanges.

[0010] In a preferred embodiment, multiple filter screens are fixedly connected to the connecting rod, and both ends of the filter screens are fixedly connected to the flow guide frame.

[0011] In a preferred embodiment, the fixed shaft is fixedly connected inside the machine head, the connecting rod is located inside the flow guide frame, and the filter element is located inside the bottle-shaped outer shell.

[0012] In a preferred embodiment, the guide vanes are obliquely and fixedly connected to the outer wall of the guide frame, and the multiple guide vanes are all airfoil structures, with the guide vanes arranged around the outer wall of the guide frame.

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

[0014] 1. Optimize water flow path: By setting multiple inclined and fixed airfoil-shaped guide vanes on the flow guide frame, the water flow can be effectively guided, the water flow resistance can be reduced, the water flow efficiency can be improved, and the water flow can be evenly distributed. This avoids the water flow directly impacting the filter element and extends the service life of the filter element.

[0015] 2. Enhanced filtration effect: The filter element is composed of 316 stainless steel filter screen. The water inlet holes on the side wall of the frame work in conjunction with the filter screen to effectively remove impurities and particulate matter from the water. In addition, multiple filter screens are fixed on the connecting rod, further enhancing the filtration effect.

[0016] 3. Ensure safe operation of the equipment: The pressure balancing valve at the outlet automatically adjusts when the pressure is too high, protecting the system from damage. The regulator on the outside of the bottle-shaped casing connects to the drain assembly, allowing users to manually remove scale and other impurities. The first sealing ring ensures a tight seal between the pump head and the fixed shaft, while the second sealing ring ensures a tight connection between the guide frame and the filter element, ensuring that untreated water passes through the filter element.

[0017] In summary, this pre-filter optimizes water flow through airfoil-shaped guide vanes on the flow guide frame, reducing resistance and distributing water evenly, thus extending filter cartridge life. The filter cartridge consists of a 316 stainless steel mesh and additional filter discs to enhance filtration efficiency. A pressure balancing valve and external regulator at the outlet ensure equipment safety and facilitate scale removal, while sealing rings ensure tight connections between components, guaranteeing effective water filtration.
