Abstract

The utility model relates to a novel tunnel type folding rail continuous sintering kiln. The novel tunnel type folding rail continuous sintering kiln comprises a kiln body of which one end is open and the other end is closed, wherein folded upper and lower layers of conveyors (3) and (2) which move in opposite directions are arranged in an inner cavity of the kiln; a slag falling prevention baffle (6) and a transportation mechanism (10) which reciprocates up and down are arranged between the two layers of conveyors (3) and (2); and a heating device (9), a gas curtain isolating nozzle (8) and a convection-preventing thermal insulation plate (7) are arranged in a main heating area of the lower inner cavity of the kiln. By using an ultra fast single-side heating and sintering mechanism and a pair of opposite conveyors which are extremely high in heat exchange and waste heat utilization rate, the novel continuous sintering kiln can sinter at an ultra high speed and is extremely high in heat efficiency and ultrashort in length.

Description

The continuous burning kiln of a kind of novel tunnel formula folding track
Technical field
The utility model relates to the Industrial Stoves that are used for the firing ceramics product, the continuous burning kiln of particularly a kind of novel tunnel formula folding track.
Background technology
At present, firing ceramics often adopts the roll shaft kiln in the industry, in addition; Also has burning kiln continuously such as tunnel cave and shuttle kiln; It is in order to improve the burnt product utilization rate of waste heat in when cooling, usually with simply the arrange in pairs or groups compound mode of drying room of burning kiln, through the backheat extractor fan; The waste heat pumpback of cooling end is treated the sintering briquette body to preheating part carry out drying, practicing thrift can heat.But existing continuous burning kiln is because the homogeneous conveying firing mode that adopts single direction; Kiln length is longer, adopts this mode dry base substrate need waste a large amount of electric energy, and a large amount of hot-fluids rejects heat in the atmosphere with extractor fan simultaneously; Heat exchange effect is undesirable, and the heat energy utilization rate is low.Labor strength is big, shortcoming big, that utilization rate of waste heat is low, firing time is long, energy consumption consumption is big takes up room so present ceramic sintering kiln exists.
Summary of the invention
The utility model technical problem to be solved provides the continuous burning kiln of novel tunnel formula folding track that a kind of reasonable in design, energy consumption are low, firing time is short.
The technical scheme of the utility model is: the continuous burning kiln of a kind of novel tunnel formula folding track, comprise kiln body, and said kiln one end opening, end sealing, said kiln inner chamber is provided with the folding transport of two-layer move toward one another up and down; The centre is provided with the baffle plate of anti-fall slag; Said kiln inner chamber blind end is provided with the carrying mechanism that matches and pump with transport; The said kiln lower floor inner chamber master thermal treatment zone is provided with heater and convection preventing thermal insulation thermal insulation board; Said kiln upper strata inner chamber is provided with fast dewatering high gradient Temperature Field Control cover and the reducing atmosphere control device chimney of holding concurrently.
Tiling has the penetrating refractory slab of lattice-shaped on the said transport, puts by burned product on the said penetrating refractory slab.
Said kiln levels inner chamber is disposed with dewatering period, redox section, the section of burning till, cooling section.
Said heater is arranged on the section of burning till bottom.
Said heater is resistance heater or fuel burner nozzle.
The two ends of the said section of burning till are provided with the combustion gas air curtain and isolate nozzle.
Said fast dewatering high gradient Temperature Field Control cover is arranged on the dewatering period top.
The said reducing atmosphere control device chimney of holding concurrently is arranged on redox section top.
Said kiln outsourcing encloses and is equipped with the insulation wall.
The each side shortcoming that the utility model exists to above-mentioned various kilns and a kind of simple, little, high heat exchange of floor space of a tightly knit structure is provided, utilization rate of waste heat is high, firing time is short burns energy-conservation kiln soon continuously; The doubling that is divided into two the delivery track of traditional kiln is cleverly arranged; The one-tenth porcelain spare of need cooling is arranged in the base substrate below that need heat; Let it absorb heat fully efficiently through heat radiation; And with brand-new base substrate single face heating fast dewatering mechanism, thereby combine the firing process effect that reaches efficient, quick, desirable.
Description of drawings
Fig. 1 is the mechanism map of the utility model kiln.
Wherein: 1 insulation wall; 2 lower layer track duct devices; 3 upper strata rail sets; 4 porcelain spares; 5 upper strata refractory slabs; 6 anti-fall slag baffle plates; 7 convection preventing thermal-insulation baffle plates; 8 combustion gas air curtains are isolated nozzle; 9 heaters; 10 carrying mechanisms that pump; 11 fast dewatering high gradient Temperature Field Control covers; The 12 reducing atmosphere control device chimney of holding concurrently; 13 lower floor's refractory slabs; 14 base substrates;
The specific embodiment
Below in conjunction with the accompanying drawing 1 and the specific embodiment the utility model is done further detailed explanation:
Shown in accompanying drawing 1; The operation principle of the utility model kiln is; The kiln body is an end and opens an end closed; Burner hearth cavity is provided with the folding two-layer up and down roll-type track conveying device 3,2 of transmission in opposite directions, and during work, the roll-type track conveying device 3 on upper strata is transported to the C end with penetrating refractory slab 5 of the lattice-shaped that is placed on it and base substrate 14 to be heated from the A end.When arriving the C end; This base substrate 14 is had the transport 10 of carrying function up and down together with its refractory slab 5 and is transported to the reverse track inlet C ' of lower floor and locates; Oppositely be delivered to C '-D section by it, in this interval, isolate 9 heating of nozzle 8 heaters through the combustion gas air curtain and burn to becoming porcelain.This becomes porcelain spare 4 to continue to be delivered to this kiln body lower open end E place by the reverse roll-type track conveying device 2 of lower floor together with the refractory slab after the heat 13 then, has promptly accomplished and has burnt till cyclic process.
In order to improve the base substrate dewatering speed; Fast dewatering high gradient Temperature Field Control cover 11 is installed at dewatering period A-B top; In order to regulate in the kiln firing atmosphere reducing atmosphere control device chimney 12 of holding concurrently is installed at redox section B-C top; The last baffle plate of the kiln section of burning till C '-D is a convection preventing thermal-insulation baffle plate 7, the peripheral whole insulation wall 1 that adopts of kiln.
This becomes porcelain spare 4 to be fed back in the kiln port of export E process together with the D place of refractory slab 13 after being heated into porcelain through heat simultaneously; The heat of high temperature that itself is contained; With the beeline path, optimal upwards convection current and radiation mode heat exchange is transferred to upper strata refractory slab 5 and base substrate 14; The levels temperature difference reaches most economical pottery and burns till state continuously keeping about 150-200 ℃ on the same fragment position.
The utility model is because of having utilized the bilevel reverse transport of folding track; Created supper-fast single face thermal dehydration specific in pottery or the pottery firing process; And firing process with high heat exchange and utilization rate of waste heat; Making it the utility model becomes and has supper-fast burning till, the continuous burning kiln that high hot utilization rate, short length and super high-yielding are imitated.
