Abstract
Zariadenie rieši problémy spočívajúce s posunom filtračného nekonečného pásu, prechádzajúcéhoTittračnou komorou·s chladenou vstupnou a výstupnou štrbinou tak, že filtračný pás je umiestnený vo filtračných doškách. Tieto sú za sebou tlačené pohonom cez štrbiny a filtračnú komoru. 0- vládanie pohonu je výhodné odvodené narastom tlaku vo filtračnej komoře.The device solves the problems of moving the filter endless belt passing through the titration chamber with a cooled inlet and outlet slot so that the filter belt is placed in the filter mats. These are pushed one behind the other by the drive through the slits and the filter chamber. 0- the control of the drive is advantageous derived from the increase in pressure in the filter chamber.
Description
Vynález rieši zariadenie na nepřetržitá filtráciu tavenin, najmá vláknotvorných polymérov, pozostávajúce z telesa filtra a filtračnou komorou, opatřenou vstupnou a výstupnou chladiacou zónou pre filtračný člen, ktoré umožňujú velmi ekonomická prevádzku pri vysokej účinnosti filtrácie.SUMMARY OF THE INVENTION The present invention provides a continuous melt filtration device, in particular fiber-forming polymers, consisting of a filter body and a filter chamber provided with an inlet and outlet cooling zone for a filter element that allows very economical operation with high filtration efficiency.
Pre kontinuálnu filtráciu sa používajú doteraz kontinuálně filtre, u ktorých posuv nekonečného filtračného pásu filtračnou komorou sa robí buď ťahom, napr. CS AO 196 876, připadne tlačením nekonečného filtračného pásu zovretého medzi perforované platničky ako uvádza CS AO 233 205. Použitie nekonečného pásu je velmi náročné ako z ekonomického hladiska, tak aj z dovodov manipulácie, připadne regenerácie týchto pásov.For continuous filtration, filters have been used so far, in which the infinite filtration belt is moved through the filter chamber either by pulling, e.g. CS AO 196 876, or by pushing an endless filter belt clamped between the perforated plates as described in CS AO 233 205. The use of the endless belt is very demanding both from the economic point of view and from the handling, the regeneration of these belts.
Uvedené nedostatky odstraňuje zariadenie podlá tohto vynálezu. Zariadenie na nepřetržitá filtráciu taveniny polymérov pozostáva z telesa filtra s filtračnou komorou, vstupného vodiaceho telesa so vstupnou štrbinou a chladičom ako aj výstupného telesa s výstupnou štrbinou a chladičom. Podstata riešenia spočívá v tom, že dížka vstupného vodiaceho telesa je váčšia ako je dížka jednej zo sady filtračných dosiek vedených za sebou vstupnou štrbinou medzi perforovanými doskami umiestnenými vo filtračnej komoře a výstupnou štrbinou. K vstupnému vodiacemu telesu je priradený mechanický pohon posunu sady filtračných dosiek spriahnutý s tlakomerom napojeným na filtračnú komoru.The above mentioned drawbacks are eliminated by the device according to the invention. The continuous melt filtration device of the polymer comprises a filter body with a filter chamber, an inlet guide body with an inlet slot and a condenser as well as an outlet body with an outlet slot and a condenser. The essence of the solution is that the length of the input guide body is greater than the length of one of the sets of filter plates guided in succession by the inlet slot between the perforated plates located in the filter chamber and the outlet slot. A mechanical drive for moving the set of filter plates coupled to a pressure gauge connected to the filter chamber is associated with the input guide body.
Na pripojenom výkrese je v pozdížnom řeze schematicky znázorněné zariadenie pre nepřetržitá filtráciu tavenin polymérov podlá tohto vynáledu pozostávajúle z telesa filtra 100 s ohrevom 110 opatřeného filtračnou komorou 120, vstupného vodiaceho telesa 500 s chladičom 210 a vstupnou štrbinou 200 ako aj výstupného telesa 600 s chladičom 220 a výstupnou štrbinou 230, z filtračných dosiek 300a, 300b, 300c, s filtračnou vložkou 310, mechanického pohonu 400 spriahnutého s tlakomerom 410 napojeným na filtračnú komoru 120. Filtračná komora 120 je horizontálně predelená perforovanými doskami 130a, 130b, medzi ktorými je medzera pre přechod filtračných dosiek s filtračnými vložkami 310.In the accompanying drawing, there is schematically shown in a schematic view of a continuous melt filtration apparatus according to the invention, comprising a filter housing 100 having a filter chamber 120, an inlet guide body 500 with a condenser 210 and an inlet slot 200 as well as an outlet body 600 with a condenser 220 and an outlet slot 230, of filter plates 300a, 300b, 300c, with filter cartridge 310, mechanical drive 400 coupled to pressure gauge 410 connected to filter chamber 120. Filter chamber 120 is horizontally divided by perforated plates 130a, 130b, between which there is a transition gap filter plates with filter inserts 310.
Filtrované médium sa privádza do dolnej časti filtračnej komory 120, prechádza následné cez perforovaná platničku 130b, filtračnú došku 300b s filtračnou vložkou 310 a perforovaná platničku 130a do hornej časti filtračnej komory 120. Filtračně došky 300a, 300b, 300c móžu byť vyrobené zo spekaných materiálov ako monolitně došky, zo sitovitého alebo iného materiálu.The filtered medium is fed to the lower part of the filter chamber 120, passed through the perforated plate 130b, the filter plate 300b with the filter element 310 and the perforated plate 130a to the upper part of the filter chamber 120. The filter plates 300a, 300b, 300c can be made of sintered materials such as monolithic thatch, of sieve or other material.
Funkcia filtračného zariadenia pre nepřetržitá filtráciu tavenin je nasledovná:The filter device function for continuous melt filtration is as follows:
Prechodom filtrovaného média cez filtračnú komoru 120 dochádza k zanášaniu filtračnej došky 300b. Po stúpnuti tlaku nad nastavená hodnotu dostane mechanický pohon 400 signál z tlakomera 410, na posun filtračných dosiek 300a, 300b, 300c, a tým aj k obnově filtračnej plochy. Po poklese tlaku vo filtračnej komoře 120 pod nastavenu hodnotu sa mechanický pohon 400 automaticky vypne. Vždy po zatlačení filtračnej došky 300a do oblasti vstupného chladiča 210 vstupného vodiaceho telesa 500 sa vysunie tlačný člen mechanického pohonu 400 a nasunie nová filtračná doska. Znečistěná filtračná doska 300c po vysunutí z výstupnej štrbiny sa odníme, bez rozoberania vyčistí a znovu je schopná opatovného nasadenia. Iíahký posuv, tvarová stabilitu filtračných dosiek ako aj utesnenie chladiacej vstupnej a výstupnej štrbiny zaručuje minimálna vól'a filtračných dosiek vo vstupnej a výstupnej štrbine filtračného zariadenia.By passing the filtered medium through the filter chamber 120, the filtering pad 300b is clogged. After the pressure has risen above the set value, the mechanical drive 400 receives a signal from the pressure gauge 410, to move the filter plates 300a, 300b, 300c and thereby restore the filtering surface. After the pressure in the filter chamber 120 drops below the set value, the mechanical drive 400 is automatically switched off. Each time the filter mat 300a is pressed into the inlet cooler 210 of the inlet guide body 500, a mechanical actuator member 400 is extended and a new filter plate is inserted. The dirty filter plate 300c is removed from the exit slot and is removed, disassembled, and re-fitted. The light feed, the shape stability of the filter plates as well as the sealing of the cooling inlet and outlet slots ensure a minimum clearance of the filter plates in the inlet and outlet slots of the filtering device.
