Abstract
The invention discloses hot wind ventilating and drying techniques for a granulation feed cabin. The hot wind ventilating and drying techniques for the granulation feed cabin comprise the following steps of opening a hot-blast furnace, setting the bot-blast furnace temperature to be T1 and preheating a drying roller; opening an air inlet of the granulation machine feed cabin, enabling temperature of hot wind from the drying roller to be T2, enabling the hot wind to be blew into the feed cabin, starting granulation and enabling the temperature of the exhaust which is discharged from an air outlet of the feed cabin to be T3; recording the T2 and the T3 all the time during the granulation process and accumulating data to gather experience for controlling volatile matters; sampling from the feed cabin, measuring the volatile matters, enabling the record to be n1, opening a feeder valve and enabling pug to enter into the drying roller when the granulation is ended; setting the drying roller rotational frequency f, performing second-step drying and enabling primary volatile matters to be n1 and dried volatile matters to be n2; simultaneously closing the feeder valve when the second-step drying is performed, performing granulation and first-step drying on next batch of pug in the granulation machine feed cabin. According to the hot wind ventilating and drying techniques for the granulation feed cabin, strict and accurate control of pug volatile matter properties is achieved through the second-step drying, secondary utilization of thermal is utilized, and energy consumption is reduced.
Description
Technical field
The present invention relates to the granulation of a kind of refractory material pug and dry methods and applications.
Background technology
The character of fire resistive material product largely depends on the character of pug, realizes quickly and efficiently that therefore the accurate control to pug character is important measures that improve the fire resistive material product performance.Usually present clay drying technique all is to carry out in drying drum in a step, fluctuation is larger, the pug fugitive constituent that easily causes drying to go out is excessive or too small, not in requiring index, have to return again drying drum and carry out redrying, perhaps mix with the next group pug, increased operation, also just prolonged the time of delivery.The time of delivery of refractory material three-major-items goods is longer at present, if can realize the accurate control of pug fugitive constituent, avoid redrying or mixing, reduce or remit unnecessary technique, can help to the shortening band of time of delivery, equally also can provide safeguard to the stable of properties of product.The refractories industry immediate profit is very thin, reduces cost, saves loss and be each producer in the problem of considering, therefore effective utilization has just become the task of top priority to the secondary of the energy.
Summary of the invention
Problem to be solved by this invention provides the logical hot-air drying technology method of a kind of granulation feed bin, by dry strict, the accurately control that realizes this character of pug fugitive constituent of two steps, to the secondary utilization of available energy, reduces energy loss.
A kind of granulation feed bin leads to the hot-air drying technology method, includes following steps:
(1) opens hot-blast stove, hot-blast furnace temperature T is set
1, the preheating and drying cylinder;
(2) opening comminutor feed bin air inlet, is T from drying drum hot blast temperature out
2, be blown into feed bin, the beginning granulation, the exhaust temperature of discharging from the feed bin air outlet is T
3
(3) in granulation process, record T always
2And T
3, accumulation data is that the control of fugitive constituent is accumulated experience;
(4) after granulation finishes, from the feed bin sampling, and measure fugitive constituent, be recorded as n
1, open the batcher valve, pug enters drying drum;
(5) the rotational frequency f of drying drum is set, carries out the second step drying, initial fugitive constituent is n
1, fugitive constituent was n after drying was finished
2
(6) when carrying out the second step drying, close the batcher valve, granulation and the first step of carrying out the next group pug in the comminutor feed bin are dry.
The present invention plants thus the technique granulation and the dry pug fugitive constituent that obtains can be precisely controlled by the control of two steps, avoid follow-up technique to carry out redrying, greatly improved production efficiency, reduction of erection time, and secondary effectively utilizes heat, reduced energy loss and cost.

(1) opens hot-blast stove 1, hot-blast furnace temperature T is set
1, preheating and drying cylinder 2;
(2) opening comminutor 3 feed bin air inlets, is T from drying drum 2 hot blast temperature out
2, be blown into feed bin, the beginning granulation, the exhaust temperature of discharging from the feed bin air outlet is T
3
(3) in granulation process, record T always
2And T
3, accumulation data is that the control of fugitive constituent is accumulated experience;
(4) after granulation finishes, from the feed bin sampling, and measure fugitive constituent, be recorded as n
1, open batcher valve 4, pug enters drying drum 2;
(5) the rotational frequency f of drying drum 2 is set, carries out the second step drying, initial fugitive constituent is n
1, fugitive constituent was n after drying was finished
2
(6) when carrying out the second step drying, close batcher valve 4, granulation and the first step of carrying out the next group pug in comminutor 3 feed bins are dry.
Record T
1, T
