Method for material feeding and liquid discharging of combined diaphragm filter plate

Abstract

The invention relates to a method for material feeding and liquid discharging of a combined diaphragm filter plate. According to the invention, a core plate is formed at the middle of a main board, diaphragms are formed at both sides of the main board, and the diaphragms and the core plate are integrally joined by heat fusion to form the integral diaphragm filter plate; and a lateral side of the main board is provided with a press hole, a material feeding passage is arranged at an outer ear part of the left upper corner of the main board, a single-chamber material feeding hole is connected with the material feeding passage, a flow-splitting hole is connected with the single-chamber feeding hole, the flow-splitting hole is connected to filter chambers on both sides of the main board, the main board and a matching board are combined to form a set of filtering unit, and the structure of the matching board is a box type filter plate. When filtering, a material enters the single-chamber feeding hole through a left-corner feeding channel of the main board, and enters a filtering chamber through the flow-splitting hole, a filtrate enters a left liquid outlet hole from a left lower cornerof one main board filter chamber, the left liquid outlet hole is connected to a left dark flow hole for discharging of the filtrate, and the filtrate in the filter cake is further reduced by pressingof a main board diaphragm, so that energy is saved, production cost is reduced, market filtration demands are met, and economy benefit is improved.

Description

Technical field [0001] The invention relates to a combined diaphragm filter plate, and more specifically, to a method for feeding and discharging a combined diaphragm filter plate. Background technique [0002] The diaphragm filter plate is the main filter element of the filter press. It is suitable for the filtration of various materials and is widely used in the solid-liquid separation industry. In order to reduce the moisture content of the filter cake, the filter cake is subjected to diaphragm pressing after the filtration is completed. After pressing, the residual water in the filter cake is discharged, and the filtrate is discharged from the four corners of the filter plate to achieve the purpose of solid-liquid separation. [0003] Due to economic development, the types of materials filtered in the solid-liquid separation industry have gradually increased. In order to improve economic efficiency and reduce costs, the currently used membrane filter plates cannot meet the need...

Problems solved by technology

[0003] Due to the development of the economy, the types of materials filtered in the solid-liquid separation industry are gradually increasing. In order to improve economic benefits and reduce costs, the currently used diaphragm filter plates cannot meet the needs of the market, the feeding time is long, the thickness of the filter cake is uneven, and the filtration speed is slow. Production costs High, so that economic benefits are affected
