Pneumatic conveying

Pneumatic conveying

Pneumatic conveying, tseem hu ua airflow conveying, yog lub tshuab thauj khoom siv lub zog ntawm huab cua los nqa tawm tas li ntawm cov khoom siv hmoov thiab granular. Hauv hluav taws xob fais fab, tshuaj lom neeg kev lag luam, khoom noj khoom haus, hlau, metallurgy, machinery manufacturing, tshuaj thiab lwm yam lag luam muaj ntau yam kev siv. Raws li qhov loj ntawm cov hmoov nqa nyob rau hauv lub roj nqa ib chav tsev ntim, nws yuav muab faib mus rau hauv dilute theem pneumatic conveying thiab concentrated theem pneumatic conveying, thaum concentrated theem pneumatic conveying muab faib mus rau hauv concentrated theem dynamic pneumatic conveying thiab concentrated theem static siab bolt. -Flow pneumatic conveying. Raws li hom kis tau tus mob tuaj yeem muab faib ua: hom suction, hom siab thiab hom sib xyaw. Pneumatic conveying system ntawm hmoov cov ntaub ntawv yuav muab faib ua hom suction, siab hom los yog ob ua ke peb.

1- tus neeg nyob ntsiag to; {{0}} ntxuam ntxuam; 3 - ib; 4- plua plav collector; 5- tawm rooj vag valve; 6- kauj valve; 7- pub rau hauv; 8- pub valve; 9- railway hopper tsheb; 10 mus rau lub cabin Lub kaw lus yooj yim, tsis muaj plua plav ya saum ntuj, thiab tuaj yeem nqa cov ntaub ntawv los ntawm ntau lub ntsiab lus tib lub sijhawm. Kev ua haujlwm siab yog qis (tsawg dua 0.1mpa), tab sis qhov kev ncua deb yog luv, thiab cov khoom siv roj sib cais muaj cov kev cai nruj nruj. Kev ua haujlwm siab yog loj (0.1 ~ 0.7mpa), qhov kev ncua deb yog ntev, qhov yuav tsum tau rau lub separator lub ntom ntim yog me ntsis qis, tab sis nws yog ib qho yooj yim rau tov nrog roj, dej. thiab lwm yam sundries, thiab lub system yog complex. Kev pub noj siab yog muab faib ua ob hom: tsis tshua muaj siab conveying thiab siab siab conveying. Kev ua haujlwm siab ntawm qhov qub feem ntau tsawg dua 0.1mpa. Cov khoom siv pub mis muaj xws li cua conveying chute, pneumatic nqa twj tso kua mis thiab lub twj tso kua mis siab siab. Kev ua haujlwm siab ntawm qhov tom kawg yog 0.1 ~ 0.7mpa, thiab cov khoom siv pub mis muaj xws li cov twj tso kua mis, cov twj tso kua mis thiab lub twj tso kua mis.

1- plua plav collector; 2- gas-khoom cais; 3- feeder; 4- blower; 5 - feed hopper Kev xa ncaj qha ntawm cov ntaub ntawv ntau, tsis ntim khoom, ua haujlwm siab. Cov cuab yeej siv yooj yim, qhov chaw me me hauv pem teb, cov nqi kho mob tsawg. Muaj peev xwm ua tiav cov chaw taws teeb tswj tsis siv neeg, cov nqi tswj qis. Flexible pipeline layout, kom lub Hoobkas khoom configuration rationalization. Nyob rau hauv cov txheej txheem conveying, cov ntaub ntawv tsis tuaj yeem yooj yim cuam tshuam los ntawm kev ntub dej, av thiab tov nrog sundries, tab sis kuj tuaj yeem txo cov plua plav, txhim kho ib puag ncig kev nyiam huv. Cov txheej txheem ntawm kev sib xyaw, muab qhab nia, ziab, cua sov, txias thiab sib cais ntawm cov ntaub ntawv tuaj yeem ua tiav ib txhij hauv cov txheej txheem conveying. Nws yog ib qho yooj yim kom paub cov concentrated, dispersed, loj qhov siab (txog 90m), kev ncua deb (txog 2000m), thiab hmoov kev thauj mus los haum rau ntau yam struts.

Kev siv hluav taws xob loj yog qhov loj, tshwj xeeb tshaj yog rau kev sib kis luv luv. Yuav tsum tau compressed cua system. Nws tsis tsim nyog rau kev xa cov ntaub ntawv uas muaj zog adhesion thiab particle loj dua 30mm. Cua thauj chute yog cov khoom siv thauj khoom hnyav theem fluidized. Nws yog tsim los ntawm ob lub plhaub plhaub ua los ntawm nyias steel phaj, nrog ib txheej breathable sandwiched ntawm ob lub plhaub. Lub chute tag nrho yog teem rau ntawm ib lub kaum sab xis. Cov khoom siv ntxiv rau hauv lub plhaub sab saud los ntawm cov khoom siv them nyiaj, thiab cov huab cua yog cua tshuab rau hauv lub plhaub qis los ntawm lub tshuab cua los ntawm huab cua permeability txheej kom fluidize cov khoom. Cov khoom siv inflatable ntws mus rau pem hauv ntej raws txoj kab nqes kom ua tiav lub hom phiaj ntawm kev thauj mus los. Cov khoom siv nws tus kheej tsis muaj qhov txav txav, yog li qhov tshwm sim ntawm kev hnav yog txo qis, ruaj khov, cov cuab yeej siv yooj yim, yooj yim txij nkawm thiab kho dua tshiab; Kev nqis peev tsawg, tsis muaj suab nrov hauv kev ua haujlwm, kev siv hluav taws xob tsawg, kev nyab xeeb thiab txhim khu kev qha; Yooj yim hloov cov kev taw qhia ntawm conveying, haum rau multi-point pub thiab multi-point unloading. Nws yog tsim rau cov khoom me me los yog cov khoom tsis sib xws. Yog hais tias muaj ntau coarse hais nyob rau hauv cov ntaub ntawv, lawv yuav accumulate nyob rau hauv lub tank thaum lub sij hawm conveying txheej txheem. Thaum lawv khaws cia rau qee qhov nyiaj, lawv tuaj yeem ua haujlwm tsuas yog tom qab phau ntawv slag tawm. Nws yog ib qho tsim nyog los xyuas kom meej tias muaj qhov tseeb downward inclination kev npaj, yog li qhov poob loj dua thaum qhov kev ncua deb ntev dua, uas ua rau muaj kev nyuaj ntawm kev tsim kho pej xeem.
