4, end cover, skeleton are galvanized treatment, not easy to rust.
5, special closed hole elastic neoprene rubber.
6. Use below 135 degrees.
Material description of the outer square and inner circle dust removal filter cylinder:
1. Ordinary domestic filter paper
2. Imported filter paper
3, flame retardant filter paper
4, ordinary polyester cloth filter paper
5, PTFE coated filter paper
6. Anti-static filter paper
Outer square inner circle dust removal filter cylinder common size:
Height: 660mm, 750mm, 800mm, 850mm, 900mm, 1000mm
External square and internal round dust removal filter cylinder cleaning mode:
High pressure gas pulse back blowing and mechanical vibration are commonly used in automatic dedusting filter cylinder. Pulse back blowing is to use the preset parameters of the controller to give a signal to the solenoid valve, instantly open and close the solenoid valve diaphragm, so that the high pressure gas into the spray pipe, using the rapid expansion force of the gas shake off the dust on the surface of the filter cylinder, the general gas pressure we set at about 6 kg force. Mechanical vibration cleaning is often used in small single filter cylinder dust collector. It uses the shaking force generated by the eccentric device on the flower plate of the dust collector to clean the dust. This action needs to be operated after shutdown.
The design wind speed of the filter drum is a key parameter, which is related to the operation effect of the whole dust filter. In general, we recommend that the design wind speed of the filter paper containing wood pulp fiber should not exceed 0.6 m/min, and the recommended design wind speed of the polyester non-woven fabric is 1 m/min. Of course, we also need to consider it in detail according to the characteristics of the filtered dust.
How to select dust filter cylinder:
1: filter cylinder selection background
The key component of the filter barrel is the filter barrel, which determines the dust removal efficiency of the filter barrel. Filtration accuracy; Filtration area; Filter wind speed and other performance. In order to meet the different needs of customers in various industries, Liffert has launched a number of filter cylinders (composite wood pulp fiber, polyester fiber filter cylinder; PTFE coated polyester fiber filter material filter cylinder) the three kinds of filter cylinder basically can meet the industrial dust removal of all processes in different industries, to achieve the desired effect of customers. Therefore, customers should choose to meet their own dust removal requirements according to the actual production situation of their own company when buying the filter.
2: filter cylinder filter material selection
Ordinary polyester non-woven fabric: made of polyester fiber materials, filtration accuracy is generally more than 5μm, applicable scope: powder spraying, sand blasting, paint, wood, cement and other industries of filtration.
Coated polyester non-woven fabric: imported PTFE coated polyester filter material, the material is made of filter cylinder long service life, high filtration accuracy, easier to reverse blow ash, up to 1-2 years under general working conditions. Scope of application: welding dust removal, shot peening, pharmaceutical, cement, tobacco, textile industry and other industries of filtration.
Anti-static polyester non-woven fabric: anti-static, that is, anti-static film treatment, is covered on the surface of the filter material with an extremely thin conductive breathable metal aluminum coating, to avoid electrostatic fire jumping, suitable for metal dust filtration, explosion-proof conditions of dust removal.
Oil-proof waterproof polyester non-woven fabric: oil-proof, waterproof and dustproof treatment is to cover a layer of fluorine resin on the filter fiber, so that the filter material has anti-oil and anti-fouling function, dust is not easy to adhere to, reverse blowing ash easier, suitable for wet or oily, dust concentration environment.
3: Installation mode
Single pass, double pass, oval, cone, triangle, etc., the user can choose the appropriate replacement filter cylinder accessories according to the original installation form of the dust filter cylinder.
Application scope of external and internal round dust removal filter cylinder:
Welding, pigments, plastics, electronics, tires, steel plate pretreatment, fly ash, ceramics, refining, rubber, cement, titanium dioxide, warehouse top materials and other dust occasions.
