Laite kuitususpension pumppaamiseksi - Anordning för pumpning av en fibersuspensionApparatus for pumping the fiber suspension - Anordning för pumpning av en fibersuspension

Esillä olevan keksinnön kohteena on laite, joka on erikoi-5 sesti tarkoitettu sovellettavaksi suursakeuksisia selluloosamassoja varten.The present invention relates to a device specially designed for application to high density cellulosic pulps.

Esillä olevan keksinnön tarkoituksena on aikaansaada massasälliöiden tyhjentämiseen soveltuva laite.The object of the present invention is to provide a device suitable for emptying pulp containers.

1010

Tunnetuissa menetelmissä massan poistaminen säiliöstä tapahtuu mekaanisten laitteiden kuten ruuvien tai pyörivien pöhjakaapimien avulla. Suursakeuksisen massan poistaminen säiliöstä vaatii paljon tehoa ja siihen tarvitaan vahvara-15 kenteisia laitteita. Massan poistamiseksi on ehdotettu käytettäväksi tärylaitteita, mm. ultraäänen käyttöön perustuvia, mutta nämä eivät ole käytännössä osoittautuneet tehokkaiksi. Isoja säiliöitä tyhjennettäessä on massa yleensä laimennettu säiliössä tyhjennysaukon läheisyydessä.In known methods, the pulp is removed from the tank by means of mechanical devices such as screws or rotary scrapers. Removing high-density pulp from a tank requires a lot of power and requires strong 15-device equipment. To remove the pulp, it has been proposed to use vibrating devices, e.g. based on the use of ultrasound, but these have not been shown to be effective in practice. When emptying large tanks, the pulp is usually diluted in the tank in the vicinity of the discharge opening.

2020

Keksinnön tarkoituksena on aikaansaada käyttövarma ja :·* yksinkertainen laite, jolla säiliöstä voidaan poistaa sen alapäässä olevan aukon kautta massaa, jonka sakeus on 5-25 %. Tämä saavutetaan siten, että saatetaan poistoaukossa 25 oleva massa pyörivän elimen avulla kuituverkostoa koossapi-. . täviä voimia suurempien leikkausvoimien vaikutuksen alaisek si niin, että massa fluidisoituu ja painovoiman vaikutuksesta valuu säiliöstä sen alla olevaan pumppuun.The object of the invention is to provide a reliable and: · * simple device with which a mass having a consistency of 5-25% can be removed from the container through an opening at its lower end. This is achieved by bringing the pulp in the outlet 25 into the fiber network together by means of a rotating member. . under the influence of higher shear forces so that the mass fluidizes and flows from the tank to the pump below it by gravity.

30 Keksintöä selostetaan seuraavassa tarkemmin viittaamalla oheiseen piirustukseen, jossa kuvio 1 esittää pystyleikkaus-ta eräästä edullisesta suoritusmuodosta ja kuvio 2 esittää • : kuviosta 1 viivaa A-A pitkin otettua leikkausta.The invention will now be described in more detail with reference to the accompanying drawing, in which Figure 1 shows a vertical section of a preferred embodiment and Figure 2 shows a section taken along line A-A in Figure 1.

35 Kuvioissa viitenumero 1 tarkoittaa massasälllötä, jonka . . alaosassa on poistojohto 2, joka on varustettu kiinnityslai- palla 3. Laippaan on kiinnitetty keskipakopumppu, jossa on sinänsä tunnetulla tavalla pyörivästi laakeroitu juoksupyörä 2 82728 5 akselilla 6. Pumpun akseliin on yhdistetty massasäiliön poistoaukkoon 7 samankeskisesti sovitettu juoksupyörän tuloaukon 8 edessä oleva roottori 9, joka ulottuu säiliön sisään. Roottorissa on ulkonemia 10 ja säiliön poistojohdos-5 sa 2 sekä pumpun imujohdossa 11 on pääasiallisesti johtojen pituussuunnassa kulkevia ulkonemia 12 ja 13. Roottorin pyöriessä säiliön poistoaukon kohdalla oleva massa joutuu alttiiksi kuitusidoksia purkaville leikkausvoimille, jolloin se fluidisoituu ja valuu painovoiman vaikutuksesta poistoau-10 kon kautta sen alla olevaan pumpun juoksupyörän tuloaukkoon.35 In the figures, reference numeral 1 denotes a mass content which. . at the bottom there is an outlet line 2 provided with a fastening flange 3. A centrifugal pump with a rotatably mounted impeller 2 82728 5 with a shaft 6 is fastened to the flange in a manner known per se. extends inside the tank. The rotor has protrusions 10 and the tank outlet line 5 sa 2 and the pump suction line 11 have protrusions 12 and 13 extending mainly in the longitudinal direction of the lines. to the pump impeller inlet below it.

Keksintö ei ole rajoitettu esitettyyn suoritusmuotoon, vaan siitä voidaan muodostaa lukuisia modifikaatioita poikkeamatta keksinnön suojapiiristä. Tarvittaessa voidaan 15 säiliö varustaa useilla poistoaukoilla, jolloin kussakin aukossa on pyörivä fluidisointielin.The invention is not limited to the embodiment shown, but numerous modifications may be made therein without departing from the scope of the invention. If necessary, the tank 15 can be provided with several outlet openings, each opening having a rotating fluidizing member.
