INTRODUCTION

The filter body is usually made of sturdy metal materials such as carbon steel or stainless steel, possessing good pressure resistance and corrosion resistance, which can provide stable support and protection for internal components. The filter screen, as the core filtering element, is generally woven from stainless steel wire, and the size of its mesh can be customized according to different filtration requirements. It can effectively intercept suspended solids, particulate impurities, and other substances in water. The hand-operated brush cleaning device is a major feature of this equipment. By turning the hand crank to drive the brush to rotate, the surface of the filter screen can be cleaned regularly to avoid the accumulation of impurities affecting the filtration effect.

The design of the water inlet and outlet ports is reasonable, ensuring smooth water flow in and out of the filter. The sewage outlet is used to discharge the impurities intercepted during the filtration process and the dirt generated when cleaning the filter screen. This equipment comes in a variety of specifications and can be flexibly selected according to factors such as the water treatment volume and installation space. It is suitable for small-scale household water filtration, pretreatment of water in commercial places, and can also play a role in some industrial scenarios where the filtration accuracy requirements are not particularly high. It is easy to install and can operate stably by relying on manual operation without the need for complex power devices, making it a practical and economical filtering option.

WORKING PRINCIPLE

The working principle of hand-operated brush filters focuses on the filtration of the filter screen and the cleaning function of the hand-operated brush. When water containing impurities enters the filter through the inlet port, under the action of water flow pressure, the water will pass through the filter screen.

Due to the specific mesh size of the filter screen, impurities in the water with particle sizes larger than the mesh, such as sediment, rust, and large suspended solids, will be intercepted on one side of the filter screen, while water and substances with particle sizes smaller than the mesh can smoothly pass through the filter screen and flow out from the outlet port, achieving preliminary filtration and making the water relatively clear. As the filtration continues, more and more impurities will adhere to the surface of the filter screen. At this time, by turning the hand crank to drive the brush to rotate along the surface of the filter screen, the brush can brush off the adhered impurities. These impurities will fall into the sewage outlet under the action of gravity and then be discharged out of the filter, enabling the filter screen to restore a good filtration state. By repeating this operation, the filtration effect can be continuously ensured.

MAIN PERFORMANCE AND CHARACTERISTICS

l Convenience of Manual Cleaning: Its biggest highlight is the hand-operated brush cleaning device. There is no need for additional complex power sources such as electricity. Only manual hand-cranking operation is required to easily clean the filter screen, remove the adhered impurities at any time, and ensure that the filter screen always maintains good filtration performance. It is especially suitable for use in places where the power supply is inconvenient or the degree of automation is not highly required.

l Stable Filtration Effect: Thanks to the high-quality filter screen, it has a reliable interception ability for common impurities in water. Although its filtration accuracy may not be as high as that of some high-precision automated filters, it performs excellently in meeting general water purification needs. It can effectively reduce the content of suspended solids and particulate impurities in water, ensuring that the filtered water reaches a certain level of clarity and purity, and is suitable for a variety of conventional water use scenarios.

l Simple and Durable Structure: The overall structural design is relatively simple, and each component is reasonably constructed. It is not prone to complex failure problems. Moreover, the use of metal materials makes the equipment have good durability. It can be used for a long time without being easily damaged, reducing the cost of frequent equipment replacement. It is also relatively easy to maintain. Only regular inspection of the wear of components and necessary maintenance such as lubrication is required.

l High Application Flexibility: Different specifications of the filter screen and equipment sizes can be flexibly selected according to different water source qualities, treatment water volumes, and specific application scenarios. It can be used for simple filtration of domestic water such as municipal water supply and groundwater, and can also play a role in the filtration of cooling water in some small industrial productions. It has good versatility and can adapt to a variety of different water treatment needs.

l Cost-Effective: Compared with some large filtering equipment equipped with complex automated control systems and high-precision filtering elements, hand-operated brush filters have a lower cost. Both the purchase price of the equipment and the subsequent operation and maintenance costs are relatively affordable. For users with limited budgets but a need for water quality filtration, it is a highly cost-effective choice.

APPLICATION FIELDS AND INDUSTRIES

l Household Water Field: In households, it can be installed at the faucet or on the whole-house water inlet pipe to conduct simple filtration of domestic water, remove impurities such as sediment and rust in the water, improve the appearance and taste of the water quality, make daily water use cleaner and more hygienic, extend the service life of water-related equipment such as faucets and water heaters, and ensure the health of family members' water use.

l Small Commercial Premises: In small commercial places such as small coffee shops, teahouses, and barbershops, there are certain requirements for the purity of water. Hand-operated brush filters can pretreat the incoming water and intercept impurities that may affect product quality or service experience in the water. For example, it can prevent impurities in the water from affecting the taste of coffee and tea or avoid impurities in the water adhering to the hair when washing hair, thereby improving the overall service quality.

l Agricultural Irrigation Field: For some small farmland irrigation systems, if the irrigation water contains a lot of impurities, it is easy to clog the irrigation nozzles. Hand-operated brush filters can filter irrigation water sources such as surface water and groundwater, remove large-particle impurities in them, ensure the smooth flow of irrigation water, enable the irrigation system to supply water to crops evenly, help to improve the yield and quality of crops, and at the same time reduce the maintenance cost of nozzle replacement.

l Some Industrial Scenarios: In some small industrial productions with relatively low filtration accuracy requirements, such as some simple machining workshops, the cooling circulating water only needs to remove larger particle impurities. Hand-operated brush filters can meet this requirement, filter the cooling water, prevent impurities from entering the equipment cooling system to cause clogging or wear, ensure the normal operation of the equipment, and reduce the equipment maintenance cost.

SUMMARY

Hand-operated brush filters, with their unique hand-operated cleaning method, stable filtration performance, and many practical characteristics, have shown good application value in multiple fields such as households, small commercial places, agricultural irrigation, and some industrial sectors. They are like the conveniently manually cleaned guardians of water quality, quietly contributing to ensuring the cleanliness and efficient utilization of water resources, helping to ensure the normal operation of various fields and improve people's living quality. With the continuous progress of science and technology, it is believed that hand-operated brush filters will continue to make breakthroughs in aspects such as material optimization, improvement of filtration accuracy, and expansion of applications, further meeting the increasingly diverse water treatment needs of society and becoming one of the practical equipment for creating a high-quality water environment and serving different industries.
