Y-Type Hand-Cranked Brush Filter

The Y-type hand-cranked brush filter has a "Y" shape in its main structure. This design is not only easy to install in the piping system, but also conducive to the even distribution and filtration of water flow. Its core components include the filter screen, the brush mechanism and the hand-cranked device, which can effectively remove impurities from the surface of the filter screen through manual rotation. This design eliminates the complex automatic control system and ensures the continuous cleaning of water quality in the most direct way. It is especially suitable for the primary filtration needs of small industrial water or domestic water.

Working principle

The core function of the Y-type hand-cranked brush filter lies in its unique design structure and high-efficiency filtration mechanism. Its working principle can be summarized as follows:

1. Inflow and preliminary separation. When a fluid containing solid particles enters the inlet of a Y-type filter, the fluid will flow along the surface of the filter due to the natural guidance of the Y-type structure. This process generates a slight eddy current effect that helps larger particles settle due to gravity or adhere to the filter due to slowing flow.

2. Fine filtration. The filter screen is a key component of filtration, and its pore size can range from tens of microns to hundreds of microns depending on the application requirements. When flowing through the filter screen, particles smaller than the pore size are trapped, and the clean fluid continues to flow downstream of the system through the filter screen.

3. Hand brushing. As the filtration progresses, the filter screen gradually accumulates impurities, resulting in an increase in pressure difference. At this time, the operator does not need to interrupt the process, just rotate the handle located outside the filter. The handle is connected to the internal brush mechanism. By rotating, the brush moves along the surface of the filter screen, effectively removing adhered solid particles and restoring the filtration efficiency of the filter screen.

Construction details

The construction of the Y-type hand-cranked brush filter reflects its design concept of high efficiency and convenience.

- Shell. Generally, high-quality cast iron or stainless steel materials are used to ensure good corrosion resistance and mechanical strength, and to adapt to different working conditions.

- Filter. Replaceable design, multiple stainless steel materials, precise aperture, not only to ensure the filtration effect, but also easy to clean and replace.

- Brushing mechanism. The built-in brush is made of wear-resistant material and is connected to the external handle through a precision-designed gear or chain drive system to ensure the effective execution of the brushing action.

- Seals. High-temperature and corrosion-resistant sealing materials are used to ensure that the filter does not leak in high-pressure environments.

- Discharge port. With a manual discharge valve, it is convenient to discharge the collected impurities during the cleaning process.

Operation process

1. Installation. Make sure the filter is properly installed in the piping system, pay attention to the flow marking, and ensure that the fluid flows from the outside of the filter to the inside.

2. Daily monitoring. Regularly monitor the pressure difference between the inlet and outlet. When the pressure difference exceeds the set value, it indicates that the filter needs to be cleaned.

3. Cleaning. Close the upstream valve of the filter, open the discharge valve to empty the internal fluid, and then shake the handle to clean the filter screen through the brush.

4. Reset and check. After cleaning, close the discharge valve, open the upstream valve, check whether it is running normally, and confirm that there is no leakage.

Scope of application

Due to its high-efficiency filtration and convenient maintenance, Y-type hand-cranked brush filters are widely used in the following fields:

- Chemical industry. Protect pumps, valves and other equipment to prevent wear and blockage caused by particulate matter.

- Oil and gas. Handle oil products, water treatment and other links to ensure the smooth flow of the pipeline system.

- Food and Beverage. Ensure that the water and raw materials used in production are pure and meet food safety standards.

- Pharmaceutical industry. In the pharmaceutical manufacturing process, high standards of cleanliness of fluids are guaranteed.

- Water treatment. Remove suspended solids in circulating water systems and cooling water systems to protect subsequent equipment.

Maintenance

- Regular inspection. Regularly check the condition of the filter screen to detect and replace damaged filters in a timely manner.

- Cleaning cycle. According to the actual use situation, develop a reasonable cleaning plan to avoid excessive pressure difference caused by not cleaning for a long time.

- Lubrication. For moving parts, such as handles and transmissions, lubricating oil should be applied regularly to maintain flexible operation.

- Record and Analysis. Record data such as time and pressure difference changes for each cleaning, analyze filtration efficiency, and optimize maintenance plans.

FAQ

1. Q: What is the function of a filter?

A: The main function of a filter is to remove solid particles, impurities, and harmful substances from liquids or gases, in order to achieve purification, clarification, and protection of equipment.

2. Q: How to choose a suitable filter?

A: When choosing a filter, factors such as the properties of the material being filtered (e.g., viscosity, temperature, corrosion), required filtration accuracy, processing capacity, operating pressure and medium, as well as the type, material, size, and installation method of the filter should be considered.

3. Q: What is the working principle of a filter?

A: The working principle of a filter mainly relies on physical screening, deep interception, absorption, or chemical reactions to remove impurities or harmful components from the material being filtered.

4. Q: How to maintain and care for a filter?

A: Maintenance of filters includes regular cleaning or replacement of filter elements, inspection of seals and fasteners, maintaining stable operating pressure, and avoiding overloading. Specific methods should be referenced from the filter's instruction manual and maintenance guides.

5. Q: What is the service life of a filter?

A: The service life of a filter depends on its working environment, processing volume, and filtration accuracy. Generally, when the filter's pressure drop reaches a certain value or the filtration effect decreases significantly, it needs to be replaced or cleaned.

6. Q: What should be paid attention to during filter installation?

A: During filter installation, attention should be paid to the directionality, ensuring that the fluid enters and exits from the correct ports. Also, the piping system should be cleaned before installation, and the filter should be securely fastened and sealed as required by the instructions.

7. Q: What is the replacement cycle for filters?

A: The replacement cycle for filters depends on their working conditions and filtration requirements, and is usually indicated by pressure difference indicators or timers. When the filter's pressure drop reaches the set value or the filtration effect decreases, it should be replaced in a timely manner.
