Abstract

The utility model relates to a spiral coil type cylinder slag cooler. The spiral coil type cylinder slag cooler comprises a base, a cylinder body fixed on the base and a power system which drives the cylinder body, wherein the cylinder body is arranged horizontally on a roller device on the base; a guide wheel is arranged on the outer wall of the cylinder body; a slag transfer pipe formed by square steel pipes or circular spiral coils through winding is arranged in the cylinder body; the front end of the cylinder body is connected with a slag inlet; a slag outlet with a downward opening is connected to the rear end of the cylinder body; one end of the slag outlet of the cylinder is provided with a water inlet pipe and a water outlet pipe which are communicated with a water inlet and a water outlet of the slag transfer pipe, respectively. The spiral coil type cylinder slag cooler is simple in structure, reasonable in design, long in service life, is easy and convenient to repair and maintain, and has a preferable water cooling effect; because a spiral sheet is replaced by the spiral coil, the heat exchange area is increased by more than three times, the cooling effect is preferable, due to the adoption of the spiral coil type cylinder slag cooler, the temperature of slag of a small discharge capacity furnace can be effectively reduced, and the temperature of the slag of a high discharge capacity furnace can be guaranteed to be reduced to be lower than 150 DEG C, and therefore the service life of the cylinder body is prolonged by more than two times.

Description

Coil barrel slag cooler

Technical field:

The utility model relates to a kind of cold slag machine, relates in particular to a kind of coil barrel slag cooler.

Background technology:

Circulating fluid-bed and boiler have been widely used in metallurgy and power industry.Coal dust fully burns and has obtained fabulous economic interests.Along with and the problem come is, the above how continuous eliminating of residue up to 850 ℃ forming after burning.Product on market adopts this structure of cylinder flight substantially, this structure due to chuck and flight heat exchange area limited, heat transfer effect is bad, when the quantity of slag is large, temperature can not be fallen, thereby high temperature furnace slag causes very big damage to follow-up equipment, once and equipment fault occurs, maintenance is inconvenient.

Utility model content:

It is a kind of simple in structure, durable, reasonable in design that the purpose of this utility model is to provide, good water-cooling effect, the coil barrel slag cooler that heat exchange efficiency is large.

For solving the problems of the technologies described above, the utility model adopts following technical scheme to be:

Coil barrel slag cooler, comprise base, be fixed on barrel on base and the dynamical system of head roll body, described barrel is horizontally set on the roller devices on base, described roller devices comprises front carrying roller and rear carrying roller, front carrying roller is groove location carrying roller, rear carrying roller is flat carrier roller, the outer wall of described barrel is provided with directive wheel, in barrel, be provided with by the slag-transporting pipe of square steel tube or the coiling of circular tube spiral coil pipe, the front end of barrel is connected with slag inlet, on slag inlet, there is slag input valve, barrel rear end is connected with the slag notch that Open Side Down, slag notch one end of barrel arranges water inlet pipe and outlet pipe, be communicated with water inlet and the delivery port of slag-transporting pipe respectively, dynamical system is arranged on a side of barrel, in the outside of barrel, is set with sprocket ring, on the output shaft of dynamical system, is arranged with sprocket wheel, by chain-driving sprocket ring, rotates, and sprocket ring drives barrel rotation.

Described slag-transporting pipe is multiple spiral coil pipe composition.

The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, high life, and easily repair and maintenance, good water-cooling effect, by spiral coil, replaced flight, heat exchange area has increased more than 3 times, can when cold slag machine rotation, slag be carried from front to back like this, carry out multi-faceted heat exchange simultaneously, and the slag contacting with helix tube can heat exchange, therefore heat exchange area is than much larger times of flight, good cooling effect, not only small displacement slag temperature can effectively reduce, and large discharge capacity slag also can guarantee that temperature drops to below 150 ℃, the barrel life-span has been increased more than 2 times.

Accompanying drawing explanation:

Fig. 1 is the utility model structural representation;

Fig. 2 is that schematic diagram is looked on a left side of Fig. 1.

In figure: carrying roller after carrying roller, 12-base, 13-dynamical system, 6-before 1-slag inlet, 2-slag input valve, 3-barrel bore, 4-slag-transporting pipe, 5-barrel, 7-slag notch, 8-water inlet pipe, 9-outlet pipe, 10-directive wheel, 11-.

The specific embodiment:

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:

With reference to Fig. 1, shown in Fig. 2, coil barrel slag cooler of the present utility model comprises base 12, be fixed on barrel 5 on base 12 and the dynamical system 13 of head roll body 5, barrel 5 is horizontally set on the roller devices on base 12, described roller devices comprises front carrying roller 11 and rear carrying roller 14, front carrying roller 11 is groove location carrying roller, rear carrying roller 14 is flat carrier roller, the outer wall of described barrel 5 is provided with directive wheel 10, in barrel 5, be provided with the slag-transporting pipe 4 forming by square steel tube or the coiling of circular tube spiral coil pipe, the front end of barrel 5 is connected with slag inlet 1, on slag inlet 1, there is slag input valve 2, barrel 5 rear ends are connected with the slag notch 7 that Open Side Down, slag notch 7 one end of barrel 5 arrange water inlet pipe 8 and outlet pipe 9, be communicated with water inlet and the delivery port of slag-transporting pipe 4 respectively, slag-transporting pipe 4 is multiple spiral coil pipe, every has independent Inlet and outlet water, greatly improved cooling effect, dynamical system 13 is arranged on a side of barrel 5, outside at barrel 5 is set with sprocket ring, on the output shaft of dynamical system 13, is arranged with sprocket wheel, by chain-driving sprocket ring, rotates, sprocket ring drives barrel 5 to rotate, thereby reach slag, carries and cooling object.

The operation principle of the utility model coil barrel slag cooler: switch on power and make dynamical system 13 drive barrel 5 to rotate, open into, outlet valve, make cooling water be full of the slag-transporting pipe 4 in barrel 5, high temperature slag charge is entered fast and is rolled simplified 5 by slag inlet 1, along with the rotation of barrel 5, slag-transporting pipe 4 drives slag charge continuous rolling to be fed forward, cooling water enters in slag-transporting pipe 4 from water inlet pipe 8, from outlet pipe 9 out, form circulation, reach the object of cooling down high-temperature slag, until discharge from the slag notch 7 of barrel 5 rear ends, make the bed of material even, loose, heat exchanger effectiveness is high.
