Abstract

The utility model discloses a simple and effective drying oven for the plain blank of glazed bricks for the production of ceramic glazed bricks, which comprises a drying chamber (1), a heater (2), a chain (3), ratchet wheels (5), a chain supporting board (6) and a blank frame (4). Kiln end waste gas and other thermal media can serve as the heat source; the utility model can work without a heater. The hot kiln wall can do the drying work when a chain type conveyer is installed nearby. The special design of the blank frame can separate the blanks piece by piece. The utility model has the advantages of high efficiency, high quality, energy saving, less investment and high blank output.

Description

Simple high-efficiency drying oven for plain blank of glazed tile

The utility model relates to a kind of simple and efficient glazed tile biscuit baker of glaze for glazed tile production usefulness.

The drying mode that present domestic glazed tile factory is adopted has three kinds, one is for to dry with tunnel cave, need tunnel cave, oven dry car and in order to keep the saggar or the can of the clean needs of biscuit, its shortcoming is that investment is big, again the factor base stack together conduct heat slow, oven dry cycle long (reach 36 hours, the shortest be no less than 8 hours) and because non-homogeneous expansion is even, very easy to crack, waste product is a lot.It two is up-to-the-minute microwave drying and infrared baking device, because of such drying equipment investment is big, and the power consumption height, the microwave tube life-span is short, and the cost of unit product is high and be not applied aspect the oven dry of glazed tile biscuit.It three is the basket-hanging drying mode, and its shortcoming is that volume is big, takes up an area of extensively, yields poorly, and it is also very slow to conduct heat, and uses very inconvenient.

The shortcoming that the existing investment of above drying mode is high, energy resource consumption is big, cost is high, yield poorly, incompatible glaze brick field at present is to energy-conservation, volume increase, the an urgent demand that reduces cost, for this reason, the utility model has designed a kind of simple and easy, energy-conservation, novel glazed tile biscuit baker efficiently.

The utility model is a kind of chain-type baker that has special base substrate frame; Mainly constitute by drying chamber (1), heater (2), chain (3), ratchet (5), chain supporting plate (6), base substrate frame (4).

Below drying chamber, heater is housed, can adopts kiln tail gas or other thermal mediums as thermal source across metallic plate; Also can be, and chain transfer is contained in (between two a kilns or kiln side) near the kiln wall without heater, penetrate heat and advection heat thermal source with kiln wall auxilliary as baker.

Base substrate frame (Fig. 2) is made with on-deformable material, continuous flute profile or waveform or " V " v notch v are processed in the inboard of its two blocks of side plates, the end face and the top board of biside plate are connected as a single entity, about base plate is divided into two, the base substrate frame (Fig. 2) that is connected with top board and forms a frame structure at its end face; The also available flat board of the biside plate of base substrate frame is inserted in (to penetrate or do not penetrate) on the biside plate with strip material (as iron bar) two ends every a segment distance and is divided into little lattice, and the design size of base substrate frame and base substrate size adapt.

Drive ratchet, ratchet drive chain by the chain drive motor, under the chain supporting plate is arranged, hold chain in order to avoid chain is sagging, the base substrate frame is put on the chain, move in drying chamber with chain, its speed of service is controlled by reduction box, with the control time of staying of biscuit in baker, glazed tile base substrate slices separately are embedded on the base substrate frame, billet surface fully is exposed in the oven dry medium, guarantee that rate of drying is fast and even, according to the structure difference of base substrate frame, base substrate can stand up or tiltedly be put on the base substrate frame.

Compare with the glazed tile biscuit baker of existing building ceramics factory, the utility model equipment is simple, takes up an area of few, the oven dry cycle short (only 1～2 hour), save the energy, use this equipment can regain equipment investment after 1 year, be specially adapted to the oven dry of middle-size and small-size glaze brick field biscuit.

Because the characteristics of newly-designed base substrate frame, can make the surface of base substrate 97% be in heat exchange and wet swap status, drying efficiency is improved greatly, oven dry in 0.5～2 hour, remaining moisture content is 1～2%, can accomplish wet base continuous feed, the continuous discharging of dry body, drying rate is fast, the output height, and the yield rate of oven dry base substrate is more than 98%; Power consumption be 6～9,000 watts hours/ten thousand bases (108 * 108m/m), utilize used heat need not increase the new energy, do not need saggar and can, operation is very easy.After evidence glazed tile biscuit adopts the oven dry of this baker, advance the pushed bat kiln roasting again, product percent of pass improves more than 10%, and output increases by 30～40%.

Adopt this technology, investment only is 1.5～30,000 yuan (every oven dry biscuit 4-8 ten thousand time).

Embodiment:

The former infrared baking device, 65,000 watts of power consumptions in the middle of two pushed bat kilns, set up of certain glaze brick field.Biscuit yield rate after the oven dry is low, have no alternative but stop using, the utility model is adopted in the back, utilize the place in the middle of its two kilns, with the kiln wall auxilliary penetrate hot and advection heat as thermal source, load onto chain conveyor, the oven dry base substrate can be for two required biscuits of pushed bat kiln calcining, oven dry back biscuit contains residual moisture 1%, 2 hours arid cycles, per ten thousand biscuit power consumptions, 6 degree; Make pushed bat kiln output increase by 15～25%, yield rate improves 8～10%, and qualified biscuit output increases by 30～40%, and effect is remarkable.
