Quick Open Multi Bag Filter Housing

The quick open multi bag filter housing is designed for industrial applications that require frequent replacement of filter bags and have strict requirements on filtration efficiency. It integrates innovative quick-opening structure and multi-bag parallel filtration technology, which is widely used in liquid filtration treatment in petroleum, chemical, pharmaceutical, food, environmental protection and other fields.

 

Structure composition

The quick open multi bag filter housing is mainly composed of the following parts:

1. Housing. Usually made of high-quality stainless steel (e.g. 304 or 316L) to ensure corrosion resistance and long-term performance. The housing is designed to be robust and able to withstand certain working pressures, and the interior space is optimized to accommodate multiple filter bags.

2. Quick opening mechanism. This is the core design of this type of filter. Generally, the upper cover can be quickly opened and closed by shaking the quick closing transmission shaft or using other quick opening and closing devices (such as buckles and hangers), without the use of tools. This greatly simplifies the replacement process of the filter bag.

3. Filter bag support frame. Located in the housing, it is used to fix and support multiple filter bags to ensure that the filter bags are evenly stressed during the filtration process and do not deform, while facilitating the loading and unloading of the filter bags.

4. Filter bags are filter media. According to the nature of the liquid to be handled and the requirements of filtration accuracy, filter bags of different materials and pore sizes are selected, such as polypropylene, nylon, PVDF, etc. Each equipment can be installed with several to dozens of filter bags to increase the filtration area and processing capacity.

5. Inlet and output pipelines. Connect external process pipelines to achieve liquid input and output, usually designed with flange connections for easy installation and sealing.

6. Exhaust valve. Located at the top, it is used to discharge the gas pressure that may be generated when the upper cover is opened to ensure safe operation.

 

Working principle

The workflow of the quick open multi bag filter housing is roughly as follows:

1. Pre-filtration stage. The liquid to be treated enters the inlet of the filter through a pump or other transportation method.

2. Main body filtration. When the liquid passes through the filter bag, solid particles or impurities are trapped on the surface or inside the filter bag, and the clean liquid continues to flow to the outlet through the filter bag.

3. Filter bag replacement. When the filter bag is blocked to a certain extent, affecting the filtration efficiency or reaching a predetermined replacement cycle, quickly open the upper cover through the quick-opening mechanism and remove the blocked filter bag for cleaning or replacement.

4. Re-assembly. After replacing the filter bag, close the upper cover, the whole process does not require complex tools, and the operation is simple and fast.

3. High flexibility. Filter bags of different materials and precision can be selected according to actual needs to adapt to a variety of filtration requirements.

4. Easy to operate. No professional skills are required, and general operators can easily replace the filter bag, reducing labor costs.

5. Durability. The stainless steel shell and internal components are corrosion-resistant and have a long service life.

6. Safe and reliable. The design of the spring balance mechanism and exhaust valve ensures the safety of the operation process.

 

Application

1. Petrochemical industry. Filtration of impurities in the refining process of processing crude oil, lubricants, fuels, etc.

2. Chemical industry. Filtration of chemicals, solvents, coatings, etc. to remove impurities in the production process.

3. Food and Beverage. Clarification and filtration of beer, beverages, edible oils, etc. to ensure product quality.

4. Pharmaceutical industry. Sterilization and filtration of pharmaceutical liquids and preparations, in line with GMP standards.

5. Environmental protection water treatment. Purification of industrial wastewater and circulating cooling water to remove suspended solids and particulate matter.

 

Operation and maintenance

1. Regular inspection. Regularly check whether the shell is leaking, whether the filter bag is damaged, and replace the damaged parts in time.

2. Filter bag management. Develop a reasonable filter bag replacement plan according to the production situation, and record the filter bag life cycle and effect.

3. Cleaning and maintenance. Filter bag cleaning should follow specific cleaning procedures to avoid the use of cleaning agents that damage the material of the filter bag.

4. Safe operation. Ensure that the system has been fully depressurized before operation and follow all safe operating procedures.

 

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.
