Description
Technical field
The present invention relates to a kind of processing of the through-hole of chemical filler field more particularly to ceramic washing chain of rings structured packing to fill
It sets.
Background technology
A kind of novel height that light porcelain packing is developed on the basis of former wood grid packing, random packing, bubble light porcelain packing
Imitate filler.It is perishable to overcome wood grid packing, random packing installation trouble, bubble lightweight filler (is burnt using raw materials low temperature such as quartz sands
Tie) the defects of water absorption rate reaches, and weight is excessively high after water suction, and compression strength is poor.The product is current coal gas, chemical industry, chemical fertilizer etc.
Industry washes naphthalene, washes ammonia, washes benzene, making packing material during desulfurization, decarburization and hot water are run and tower and direct cooling tower.
The ceramic washing chain of rings is a kind of bulk, porous, specific surface is big, light specific gravity, the regular complete light porcelain material being arranged in tower
Material.In installation tower between upper and lower layer, is separated by the support leg of itself, make airflow uniform distribution, overcome the hair caused by random packing
Disease greatly reduces resistance, and in mass transport process, filler surface remains certain liquid film, forms good gas-liquid contact etc.
Feature.Full porcelain composite filling is to add combustible material as primary raw material using siliceous clay, is made by the way that various processes are quiet, it has
Following advantages：Acidproof, alkaline-resisting, organic solvent-resistant, high temperature resistant, thermal stability are good, and pressure resistance, resistance to bending are high, regular arrangement, operation
Resistance is small, inexpensive, easy for installation.This makes the ceramic washing chain of rings be widely used in producer gas scrubbing tower；Coking coal air purge benzene,
Wash naphthalene, Ammonic washing tower；Chemical fertilizer hot water saturator, decarburization, desulfurizing tower；CO in limestone kiln2Clean tower and oil refining, chemical engineering, pottery
Porcelain washing is a chain of especially suitable for extraction and fractional distillation process.
Existing ceramic washing chain of rings structured packing includes filler body, and filler body includes a center ring and multigroup side ring,
Every group of side ring circumferential direction positioned opposite in center ring, each side ring are connected with the outer wall of center ring, are opened up on same group of side ring
There is the through-hole through center ring.The mode of production of ceramic washing chain of rings structured packing is to be mixed by a certain percentage using pug and water
It closes, the mold of specific shape is loaded onto on ceramics extrusion machine, with ceramics extrusion machine extrusion molding filler body, and then utilization
Manually filler body is positioned over into punch die, is opened up in the through hole of ceramic washing chain of rings structured packing at punch die is upper
There are through hole, worker to pass through using steel wire and realized to the through-hole in ceramic washing chain of rings structured packing at the through hole on punch die
It is processed molding, since through-hole cannot be directly by ceramics extrusion machine extrusion molding, through-hole in ceramic washing chain of rings structured packing
Machine-shaping process it is relatively complicated, there are the less efficient problems of machine-shaping of ceramic washing chain of rings structured packing.

Cutting somebody's hair, an air pump is set on 42, the high pressure gas that air pump generates is blown by each gas hole to waste material through centre bore,
The phenomenon that being adhered so as to avoid waste material occurs.
To sum up, extruder squeezes out the not filler body with through-hole, filler body and is transported at fixed platform 2, worker
At fixed platform 2, worker will not be inserted at the filler body of hole machined in each molding sleeve 3, and driving motor passes through transmission
Axis 71 drives 72 uniform rotation of drive disk, drive disk 72 to rotate one week and realize to first strip-shaped hole of one of telophragma 6 61
Stir primary so that turntable 5 is followed by telophragma 6 and turns over an angle, in this way, realizing the rotation one every time of drive disk 72
Week, turntable 5 just turn over an angle, meanwhile, in 5 rotation process of turntable, on the one hand, stir the insertion pair of column 52 on turntable 5
One of answer on a rotary disk 8 second strip-shaped hole 821 so that corresponding rotary disk 8 turns over an angle simultaneously, revolution
Molding sleeve 3 on axis 81 is followed by revolution ontology 82 and rotates synchronously, and on the other hand, turntable 5 drives column 60 to rotate simultaneously, this
Sample also follows turntable 5 to rotate synchronously on column 60 at aperture member 4 so that multiple molding sleeves 3 in fixed platform 2 successively around
Central axis rotates an angle, and column 60 accordingly turns over identical angle at aperture member 4, ensure that each pore-forming
Component 4 can be directed at the molding sleeve 3 rotated around central axis, in this way, in molding sleeve 3 after own axis, stand
41 synchronization action of pore-forming cylinder on column 60 is realized pair at the insertion hole 32 of the corresponding molding sleeve of 42 insertions of cutting somebody's hair of aperture member 43
Filler body in it carries out one-step pore-creating processing, in this way, the continuously and smoothly with driving motor rotates, when in fixed platform 2
Each molding sleeve 3 occur once to rotate successively, the filler body in each molding sleeve 3 completes one-step pore-creating processing, realizes one
The secondary pore-forming period, by cyclic process several times, you can complete to carry out at hole machined, separately whole through-holes 13 in filler body
Outside, when after processing is completed, in addition the filler body in several molding sleeves 3 also will successively for filler body in one of molding sleeve 3
Complete processing, cut somebody's hair 42 turn to one of molding sleeve 3 again before, worker is by the filler in one of molding sleeve 3
Ontology takes out, and then the filler body for not carrying out into hole machined is put into molding sleeve 3, you can realize cut somebody's hair 42 it is continuous
Processing, improve the pore-forming efficiency of filler body, therefore, by using the present invention through-hole processing unit (plant), worker need to only be responsible for by
The filler body for not carrying out into hole machined is put into molding sleeve 3, and by filler body after processing is completed, taking-up is out of molding sleeve 3
Can, the filler body that through-hole machines integrally is re-fed into oven case and is toasted, simultaneously as each molding sleeve 3 is spaced
Rotation provides the sufficient time to picking and placeing for filler body, realizes the semi-automatic mistake of ceramic washing chain of rings structured packing 1
Journey improves the manufacture efficiency of 1 through-hole 13 of ceramic washing chain of rings structured packing processing.
