Abstract
The invention relates to a filter candle which has a simple and novel structure and particularly performs solid-liquid separation aiming at severe environments such as a strong corrosion environment and the like and a filter method. A candle connecting head, a communicating head and a candle are welded by hot melting; the communicating head, a tail welding block and an outer bushing are welded by hot melting; the tail welding block is connected with a positioning rod connecting block by using a bolt; and the candle and a filtering cloth sleeve are connected and sealed through a seal ring and a hoop. The invention has the advantages that: 1, the filter candle has a novel, unique and simple structure; 2, the filter candle has light weight and high strength, is low in cost and can perform the solid-liquid separation under the severe environments such as the strong corrosion environment and the like due to the adoption of a corrosion-resistant plastic material; 3, the filter candle has a firm integral structure and long service life; and 4, a filter cake is convenient to disassemble.
Description
Technical field
The present invention relates to a kind of simple in structurely, novel, carry out the filter candle and the filter method of Separation of Solid and Liquid especially to adverse circumstances such as deep-etching, belong to airtight pressing filter and make the field.
Background technology
Filter is of a great variety, comprises types such as centrifugal, vacuum, membrane filtration.Though the filter of these types has characteristics separately, because of candle filter simple in structure, long service life, good filtration effect and being widely used in industries such as wine brewing, beverage, medicine, chemical industry, environmental protection day by day.Used filter element was the filter candle rod in the candle filter, and the candle filter of producing both at home and abroad at present mostly adopts the spiral candle post of flat spring of adjustable clearance, in use; Need often to clean adjustment, tend to occur spiral candle intercolumniation crack and differ in size, influence the flow and the turbidity of filtrate; Simultaneously; Because it is heavy that this type machine filters end socket, during cleaning, the lifting difficulty.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of simple in structure, long service life, easy to maintenance and can carry out the filter candle and the filter method of Separation of Solid and Liquid to adverse circumstances such as deep-etchings.
Design: to achieve these goals.1, the candle pipe is made up of the six roots of sensation screen pipe around a center filtrate pipe, and the purpose of doing like this is: see that from the cross section of candle pipe this layout is similar with plum blossom, so can be described as seven apertures in the human head plum blossom candle pipe again.The peripheral every screen pipe outside is furnished with convex tendon, and the alternate place of convex tendon has aperture.This unusual design can make the filter cake can be well attached to above the filter medium (cloth).In the pressure filtration process, the recess of filter element can make filter cake be close to the surface of filter cloth, thereby guarantees that filter cake can arbitrarily not move displacement in whole filter cycle.Protruding rib one side can strengthen the bulk strength of candle pipe, thereby can avoid filter cloth upward to block the little hole path of fluid on it because of receiving external compression to be attached to the candle pipe on the other hand again, causes fluid not smooth, influences fluid speed.2, for adapting to corrosion adverse circumstances such as acid, alkali; The extrusion molding of this pipe material by adopting glass enhanced polypropylene; The purpose of doing like this is: it can carry Korrosionsmediums such as acid, alkali and salt within 120 ° of C of temperature, and can carry out the sweat soldering processing and forming with polypropylene board.3, candle tube head thermofussion welding is connected to and is similar to metal insert joint in the PP-R hot and cold water pipeline system, thus easily realize and collector tube between installation and removal.4. be the UNICOM that realizes between outer ring candle pipe and the central tube, manage UNICOM's head that the other end is welded with a groove at candle, through this cavity conducting peripheral tube and central tube.The buoyancy that the candle pipe produces when 5, filtering for payment is to himself stability with to the active force of upper support fixed coupling unit, specially is welded with a hollow pipe in UNICOM head bottom, and inside is packaged with a plumbous heavy rod.6, in order to improve the intensity of the candle pipe of being installed on the same exhausting liquid collecting pipe, the ad hoc candle pipe backstay of putting is strengthened.Through the adjustable perfect square in bottom to candle pipe backstay coupling block make it to be concatenated into one, thereby improved the ability of whole anti-current body impulsive force.7, for realizing filtering purpose; Candle pipe is outside to be with the filter felt of a ultrasonic wave melting welding of exempting to make; The sealed attachment at two ends is realized through two steel wire clips and sealed loop-pad in two ends, effectively prevents to filter, race liquid, short circuit and gas leak phenomenon when cake is unloaded in washing and blowback.8, filter type of this candle pipe: in the pressure filtration process, liquid passes filter cloth from the outside of filter element, and the solid particle in the liquid is collected in the surface of filter cloth, forms to be divided into the filtration of building bridge of uniform one deck filter cake.Because the profile of filter element has and recessedly has protrudingly, has certain pressure reduction inside and outside the pipe, so filter cake is always attached to the surface of filter candle.Leach clear liquid and flow downward, compile the entering central tube then in the bottom, sail against the current, arrive the collecting pipe at top at last, discharge airtight pressurizing vessel through extension tube attached through the concentric screen pipe of the six roots of sensation.When unloading cake, utilize the impact of back draught, just can split away off attached to the lip-deep filter cake of candle pipe filter cloth.When filter cloth is got up by the air-flow inflation, the crack of vertical direction will appear on the filter cake, no longer become big reach its maximum distortion at medium after, filter cake just drops one after another.
Technical scheme 1: filter candle, adopt sweat soldering between the coupling head of candle pipe, UNICOM's head and the candle pipe; Adopt sweat soldering between UNICOM's head, tail welding block and the outer tube; Adopt Bolt Connection to form between tail welding block and the backstay coupling block, connect sealing through sealing ring and clip realization between candle pipe and the filter cloth cover.
Technical scheme 2: a kind of filter method of filter candle, in the pressure filtration process, liquid passes filter cloth from the outside of filter element; Solid particle in the liquid is collected in the surface of filter cloth, form to be divided into filtrations of building bridge of uniform one deck filter cake, owing to the profile of filter element have recessed have protruding; Have certain pressure reduction inside and outside the pipe, thus filter cake always attached to the surface of filter candle, it leaches clear liquid and flows downward through the concentric screen pipe of the six roots of sensation; Compile the entering central tube then in the bottom; Sail against the current, arrive the collecting pipe at top at last, discharge airtight pressurizing vessel through extension tube attached; When unloading cake, utilize the impact of back draught, just can split away off attached to the lip-deep filter cake of candle pipe filter cloth; When filter cloth is got up by the air-flow inflation, the crack of vertical direction will appear on the filter cake, no longer become big reach its maximum distortion at medium after, filter cake just drops one after another.
The present invention compares with background technology, and the one, novel structure, uniqueness, simple; Two are to use corrosion resistant plastic material, in light weight, and intensity is high, and cost is low, can in adverse circumstances such as deep-etching, carry out Separation of Solid and Liquid; The 3rd, overall structure is firm, long service life; The 4th, it is convenient to unload cake.
