Flexible tube press for sludge cake discharge by extrusion method with multi-layer permeable panels

Abstract

The invention discloses a flexible tube presser for discharging a mud cake by using a multi-layer water permeable plate through an extrusion method. A filter element of the flexible tube presser comprises an upper flange, a filter tube unit, a filter chamber forward and backward limiting structure, a filter chamber leftward and rightward limiting mechanism, a horizontal filtrate collection tray and a mechanical slag removal assembly, wherein the upper flange comprises a filter chamber upper sealing structure and a traveling mechanism; guide wheels of the traveling mechanism are arranged on the left side and the right side of the upper flange and are engaged with a stand guide rail respectively; in the machinery, the mud cake is discharged by using the extrusion method; at least one water permeable plate and a collection tube are arranged in a filter chamber; each water permeable plate comprises at least three layers of plate-shaped filter mediums, a plate locking strip, a suspension assembly, a filter cloth tightening mechanism, an edge covering corner strip, a water discharge conduit port and a fluid inlet orifice; and a treatment process is automatically finished by the water permeable plate due to the small size, simple structure, high pressure resistance, light weight, reliable sealing, large water absorption area, long life, high filtering speed, high efficiency, large treatment scale and low running cost of the water permeable plate.

Description

Technical field [0001] The invention relates to a flexible tube press for discharging sludge cake by the extrusion method of multi-layer permeable plates for solid-liquid treatment of viscous and fine-grained materials, and is particularly suitable for papermaking wastewater treatment, sludge treatment, river dredging mud treatment, Hydrometallurgical wastewater treatment, coal washing wastewater treatment, and livestock and poultry breeding industry pollutants treatment. Background technique [0002] Among the existing flexible tube squeezing solid-liquid separation devices, for example, "Flexible tube filter" patent number 200410077975.0, "flexible tube squeezing solid-liquid separation device" patent application number 2009201586128, "fast flexible tube squeezing solid-liquid separation device" "Patent application number 20091017966.0, "Fast and ultra-large-scale flexible tube squeezing solid-liquid separation device" patent application number 2009101329956, there are many kno...

Problems solved by technology

[0011] In Patent Application No. 2009201586128 of "Flexible Tube Pressing Solid-Liquid Separation Device", the technical scheme of permeable partition layer for multi-layer filter chamber is proposed, and the end of one side of the partition layer is connected to the inner side of the vertical wall of the steel wire braided conveyor belt in the outermost layer of the filter tube unit. Contact, the gap in the filter press permeable layer is connected to the annular filtrate collection chamber, the manufacturing cost is high, and it is difficult to maintain and replace the filter cloth; it is proposed in the technical solution of the patent application number 2009101329956 of "Flexible Tube Press Solid-Liquid Separation Device for Rapid Ultra-Large Processing Scale" The technical solution for the expansion and vibration of the filter chamber of the plumb rapping mechanism is relatively complicated and the manufacturing cost is relatively high
