Rocker Arm Multi-Bag Bag Filter Housing

The rocker arm multi-bag bag filter housing is designed for high-capacity or high-flow filtration needs. It offers a conventional 2-12 bag design, and up to 24 bags can be used in a single machine if required. The filter features a quick-open design with a cover to assist in lifting the boom for easy operation and maintenance.

 

Structural design

The core of the rocker arm multi-bag bag filter housing lies in its unique design, which is reflected not only in the layout of the filter unit, but also in the ease of operation. The equipment is usually composed of the following key components:

1. Shell

Made of stainless steel or other corrosion-resistant materials, it provides a solid external environment for the filter unit. The shell is designed with liquid inlet, liquid outlet and slag discharge port to ensure smooth flow of liquid and easy cleaning.

2. Rocker arm mechanism

This innovative design is a hallmark feature of this type of filter. The rocker arm is connected to the opening device at the top of the filter through a mechanical linkage, allowing the entire filter bag group to be easily lifted for quick replacement or cleaning of the filter bag, greatly simplifying routine maintenance.

3. Multi-bag filter unit

Multiple filter bags are installed inside. These filter bags are made of high-strength, chemical-resistant materials, and different pore sizes are selected according to the filtration needs. The filter bags are fixed through metal mesh baskets or support frames to ensure that the filter bags remain stable during the filtration process and will not be deformed by pressure.

4. Quick-opening design

The rocker arm multi-bag filter housings are equipped with a quick-opening cover design, which can be quickly opened by simple operation to expose the filter bag for inspection or replacement, reducing downtime.

Working principle

In practice, the liquid to be filtered enters from the liquid inlet of the equipment, and then flows through multiple filter bags under the pressure. As a filter medium, the filter bag can effectively block impurities such as solid particles and suspended solids in the liquid, allowing only the clean liquid to pass through the tiny pores between the fibers of the filter bag, and finally discharged from the liquid outlet. As the filtration process continues, impurities gradually accumulate on the surface of the filter bag, forming a filter cake layer, which actually enhances the filtration effect. When the filter bag is blocked to a certain extent, affecting the filtration efficiency or reaching a predetermined replacement cycle, the filter bag group can be easily lifted through the rocker arm mechanism to clean or replace the filter bag.

 

Technical features

1. High efficiency

Due to the large surface area of the filter bag and the ability to use multiple filter bags simultaneously, the flow rate per unit time is large, the filtration efficiency is high, and it is suitable for large flow or high pollution level liquid treatment.

2. Flexibility

According to actual needs, filter bags of different materials and pore sizes can be selected to achieve a wide range of applicability from coarse filtration to precision filtration.

3. Low cost

Although the initial investment may be slightly higher than some traditional filtration equipment, it is due to its high filtration efficiency, low filter bag replacement cost, and low long-term operating costs.

4. Easy to maintain

The rocker arm design makes the replacement of the filter bag quick and easy, without the need for professional tools, reducing the difficulty and time cost of maintenance.

5. Strong adaptability

Suitable for a variety of working conditions, including extreme conditions such as high temperature, high pressure, and strong corrosion, and can adjust the number of filter bags as needed to meet the needs of different flow rates and filtration accuracy.

 

Application field

The rocker arm multi-bag bag filter housing is widely used in chemical, pharmaceutical, food and beverage, environmental protection, water treatment, petroleum, electronics, power and other industries. Specific application examples include:

1. Chemical industry. Raw material purification, solvent recovery, paint filtration, etc.

2. Pharmaceutical industry. Liquid purification, injection filtration, API filtration, etc.

3. Food and Beverage. Clear filtration of syrups, juices, beers, and dairy products.

4. Environmental protection water treatment. Wastewater pretreatment, wastewater reuse system filtration link.

5. Electronics industry. Pre-filtration of ultrapure water, chemical liquid filtration in semiconductor manufacturing.

 

Maintenance

1. Regular inspection. Regularly check the sealing performance of the filter to ensure that there is no leakage.

2. Filter bag management. Record the replacement cycle of the filter bag, and replace the filter bag in a timely manner according to the nature of the filter medium and the amount of filtration, so as to avoid affecting the filtration effect due to the blockage of the filter bag.

3. Cleaning and maintenance. After each replacement of the filter bag, the inside of the shell should be thoroughly cleaned to prevent residual impurities from affecting the next filtration effect.

4. Accessories inspection. Regularly check the wear of moving parts such as rocker arm mechanism and quick opening cover, and replace the worn parts in time.

 

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.
