Centrifugal type preposed filtering device

Abstract

The invention discloses a centrifugal type preposed filtering device. The filtering device comprises a top plate, and a bottom plate and side plates which are fixedly connected with the top plate. The filtering device also comprises a filtering unit, wherein the filtering unit comprises blade hole plates, blind plates and Z-shaped groove plates; one side edge of each blade hole plate coincides with one edge of the corresponding blind plate, the lower end part of the coinciding edge of the blind plate is connected with one Z-shaped groove plate through a rivet, and the other side edge of the blade hole plate is connected with another blind plate adjacent to the blind plate; the blind plates and the blade hole plates are sequentially connected to form an M-shaped structure. Since the filtering device is made from galvanized plates or stainless steel plates and the distribution of filtering holes conforms to the gas flowing principle, the filtering device has the advantages of being high in purification efficiency, free form replacement of filtering elements, low in operation resistance and convenient to clean and maintain.

Description

Technical field [0001] The invention relates to an oil mist filter device, in particular to a centrifugal pre-filter device in an oil mist purifier. Background technique [0002] Nowadays, with the continuous economic development, more and more industrial machinery are used in large quantities. However, in the metal processing process such as turning, milling, drilling and grinding, due to the use of metal cutting fluid, a large number of oil mist particles will be formed in the air; Working in such an environment, oil mist particles will be adsorbed in the lungs of the human body, causing great harm to human health. Therefore, the oil mist particles in the workshop are filtered out, the working environment of the processing workshop is improved, and the air in the workshop is kept clean. It is a topic worthy of the common attention of factory managers and occupational safety and health management agencies. In the prior art, the pre-filter of oil mist purification equipment still...

Problems solved by technology

[0002] Today, with the continuous development of the economy, more and more industrial machinery is used in large quantities, but in metal processing processes such as turning, milling, drilling and grinding, a large number of oil mist particles will be formed in the air due to the use of metal cutting fluid; long-term Working in such an environment, the oil mist particles will be adsorbed in the lungs of the human body, which will cause great harm to human health. Therefore, filter the oil mist particles in the workshop, improve the working environment of the processing workshop, and keep the air in the workshop clean. It is a topic worthy of common attention by factory managers and occupational safety and health management agencies. In the prior art, the pre-filter of oil mist purification equipment still has the disadvantages of low purification efficiency and poor purification effect. Poor, it will inevitably increase the workload of the follow-up purification equipment, resulting in slow progress of the purification work, and also cause waste of energy to a certain extent
