Description
Technical field
The present invention relates to a kind of for firing the kiln car kiln furnitures of electroceramics.
Background technique
Electroceramics is also referred to as bar-shaped porcelain insulator, is the extra-high voltage components of UHV Transmission Engineering, for set up high-tension bus-bar,
And make have enough distances and insulation between high-tension bus-bar and supporter, therefore the performance of electroceramics is to the exhausted of system for ultra-high voltage transmission
Edge effect and safety play very important effect.
Currently, the specification and shape due to electroceramics are not quite similar, in sintering procedure, the electroceramics of small dimension is usually used
Hold in the palm the firing process burnt；And the electroceramics of big specification is since weight weight, size are big, if it is simple using the firing mode for hanging burning if green body
It can not form；If the simple firing mode burnt using support makes electrotechnical porcelain product be also easy to produce bending deformation, so as to cause big stick electricity
Porcelain products it is off quality, be unable to satisfy the requirement of extra-high voltage project.Chinese patent discloses a kind of firing of big rod type electroceramics
Method, the method that burning is hung after using first seat to burn, this is a kind of process for calcining of ideal type, but this method is in terms of kiln car kiln furnitures
Lack and embodies, such as: the green body obtained after shaping and drying is uprightly placed on kiln car firstly, seat burns system, it is well known that kiln
The temperature of vehicle is lower, if green body is uprightly placed on kiln car, the bottom of green body is because thermal convection is poor, to increase it
Energy consumption；Secondly, fixing the green body with kiln furnitures, the green body is equipped with the suspending head for hanging sintering briquette body, wherein " kiln furnitures "
Too upperseat concept speculates that " kiln furnitures " should be the lantern ring with support construction, just according to the context of specification
It can be used to fix the green body, in addition, suspending head is possessed on green body, or be arranged to hang sintering briquette body, this
So that those skilled in the art are difficult to carry out the present invention.
Summary of the invention
The purpose of the present invention is to provide a kind of for firing the kiln car kiln furnitures of electroceramics, it is intended to meet existing larger specification
The firing of electrotechnical porcelain product, making it, not only product shape is regular, straightness is good, but also qualification rate is high, is able to satisfy extra-high voltage project and wants
It asks.
The present invention, including kiln car, at least provided with 4 root posts on kiln car, on column, equipped with being parallel to kiln car advance side
To layer hole, girder is respectively arranged on the bottom layer hole and top layer layer hole between adjacent two root posts, on bottom layer hole
Two sides girder between joist is set, place backing plate on every two joists, every piece of backing plate is for loading an electroceramics green body, electricity
Porcelain billet body vertically loads, and bottom is placed on backing plate, the quantity and place the density of backing plate to ensure electroceramics base that joist is set up
The distance between body is advisable not less than 10mm, and hanging beam is arranged between the two sides girder in upper hole layer by layer, in every row electroceramics green body
A pair of of hanging beam is arranged in two sides, hangs the radial through-hole that depth of beam is lower than electroceramics green body upper end, the radial direction on every electroceramics green body
Through-hole is equipped with a root cutting stick, and the length of plunger should be equal to greatly the distance between the two sides hanging beam outer side edges of electroceramics green body.
The present invention is equipped with the guard beam hole of layer 2-3, between adjacent two root posts between bottom layer hole and top layer layer hole
Guard beam is arranged on hole in guard beam.
The present invention, bottom layer hole and top layer layer hole are layer lofty tone knothole, and the height of layer lofty tone knothole is greater than girder
Highly, layer top adjustment cushion block can be set on bottom layer hole or/and top layer layer hole, cushion block is located at the lower section of girder.
The present invention is equipped with a material reducing plane, in the sintering procedure of electroceramics green body, because of electroceramics in the downside of the plunger
Green body gradually tapers up, when shrinking to a certain extent, the material reducing plane and hanging beam upper surface parallel contact.
The present invention has a characteristic that
1, first electroceramics green body is loaded on joist, carries out support burning, in the sintering procedure of electroceramics green body, gradually because of electroceramics green body
It shrinks, when shrinking to a certain extent, electroceramics green body is erected on a pair of of hanging beam by plunger, and it carries out hanging burning, is burnt from support and hang burning,
Whole process electroceramics green body is supported by kiln furnitures, is not contacted with kiln car, and electroceramics green body is heated evenly, it is ensured that the matter of electrotechnical porcelain product
Amount.
2, bottom layer hole and top layer layer hole are designed as layer lofty tone knothole, are convenient on bottom layer hole or/and top layer layer hole,
Layer top adjustment cushion block is set, meets after different electroceramics green bodies first hold in the palms burning and hangs the requirement for height of burning.
3, due between bottom layer hole and top layer layer hole be equipped with layer 2-3 guard beam hole, between adjacent two root posts
Guard beam is arranged on hole in guard beam, and the effect that guard beam is arranged was because of the phenomenon that effectivelying prevent electroceramics green body to topple over to two sides when vibration.
If electroceramics green body is toppled over to two sides, dead kiln will be caused, i.e. kiln car cannot be preceding and then be blocked, it is necessary to which flame-out cleaning is stopped working and cleared up
It will cause serious loss.
4, the radial through-hole above electroceramics green body is technical characteristic possessed by electrotechnical porcelain product, is not due to this firing process
It is arranged, therefore, the present invention can obtain the effect got twice the result with half the effort using the radial through-hole on electrotechnical porcelain product to design the present invention,
Using the column and girder on existing kiln car, only increase joist and plunger, electroceramics green body can be lifted and be fired, saves a large amount of
Kiln furnitures, kiln furnitures accounting is small, not only saves kiln furnitures cost, while also energy-saving.
5, plunger of the invention, be on the basis of a hollow pole by the way of material reducing on the downside of it, setting
One material reducing plane notices that the material reducing plane is downward, in the firing of electroceramics green body when plunger is injected the radial through-hole of electroceramics green body
In the process, because electroceramics green body gradually tapers up, when shrinking to a certain extent, the material reducing plane and hanging beam upper surface parallel contact,
Increase the frictional force between plunger and hanging beam, so that the rolling of kiln car plunger during traveling is prevented, if kiln car is expert at
Plunger rolls during, then will generate the phenomenon that electroceramics green body is toppled over.
6, of the invention, the hollow pole equipped with a material reducing plane has carrying high mechanical strength, is easy to compared with square bar
The advantages that processing.
The present invention has structure novel, and the electroceramics green body quantity of loading is more, and product and kiln furnitures ratio are high, energy-saving, energy
Meet the firing of the electrotechnical porcelain product of existing larger specification, not only product shape is regular, straightness is good, but also qualification rate is high, can be full
The requirement of sufficient extra-high voltage project.
