The leaf filter is a new type of precision filtering equipment. The equipment has the characteristics of high efficiency, energy saving, and airtight operation. It is widely used in chemical, petroleum, food, pharmaceutical and other industries.
The design and structure of the leaf filter is novel. It adopts horizontal suspension installation, the cylinder can move horizontally back and forth under the action of the hydraulic system, which can expose the mesh plate to the outside, which is convenient for slag removal and mesh cleaning. The use of vibration slag can reduce labor intensity, sealed double-sided filtration, large filtration area without environmental pollution, etc. At the same time, stainless steel mesh is used, without filter paper and filter cloth, which greatly reduces the cost of filtration and meets the requirements of high-output and high-precision filtration need.
How does the leaf filter achieve slag removal?
The filter is used to filter grease materials, and the filter screen is equipped with an automatic vibration slag removal device. The vibrator is mainly composed of a cylinder and a reciprocating piston, when the compressed air passes through the oil mist. The intake product enters the cylinder and pushes the piston to reciprocate to generate vibration. The vibration frequency of the vibrator is adjusted by a pressure regulator installed at the air inlet. The vibration frequency is proportional to the intake pressure. The air pressure range of the vibrator is 0.4-0.6MPA. The amplitude of the vibrator is adjusted by the increase or decrease of the weight behind the cylinder cover of the vibrator. The amplitude is proportional to the weight of the weight. In order to make the vibrating and slag removal more thorough, it is necessary to adjust the vibration amplitude and the vibrator accordingly according to the viscosity properties of the filter residue. frequency.
The filter with vibrator has a special locking mechanism in the middle of the filter plate in the filter cylinder. The outer end of the filter cylinder is equipped with a vibrator. The reciprocating vibration of the vibrator is transmitted to the mesh plate, so that it is attached to the filter plate. The filter residue falls off.
The filter screen of the leaf filter is cleaned in a pure pool. The cleaning solution is 10-15% NAOH solution (or a non-corrosive cleaning solution for the filter screen). The temperature is 50-60°C. The cleaning time is generally not more than 3 Be careful not to use hydrochloric acid or detergents that produce free chloride ions to clean it, because it will seriously corrode the filter.
