Abstract

The utility model relates to a cold slag remover, particularly a cold slag removing device for boilers, which comprises a machine frame, a cold slag rotary drum and a driving device, wherein the cold slag rotary drum is composed of regular polygonal isolated pipes which are tightly interphase and each corner of the isolated pipes is welded with a cooling circular pipe. Compared with the background art, the utility model adopts cooling circular pipes through which cooling water can pass, therefore the entire device has high water pressure resistance. Meanwhile, the straight ribs or spiral plates added on the utility model can increase the cooling area of high-temperature material in the process of cooling, increase heat exchange efficiency and increase cooling speed. Under the condition of the same material flow capacity, the required rotation speed of the utility model can greatly descend, so the utility model has the advantages of smaller abrasion and longer service life, and meanwhile, the power consumption can also be reduced.

Description

Cold-slag slagging equipment

(1) technical field

The utility model relates to a kind of solid material cooling device, particularly a kind of cold-slag slagging device that is used for boiler.

(2) background technology

The applicant's SEPARATE APPLICATION formerly patents such as 95111150.7,95240292.0,96232004.8,99114028.1, its device that provides has solved cold-slag slagging problem of the prior art preferably.Above-mentioned cold-slag slagging equipment, comprise frame, cold slag rotating cylinder, drive unit, be provided with pipe in the cold slag rotating cylinder, particularly when pipe adopted the polygon pipe, there are the following problems: cinder rolled in the polygon pipe, and cooling water is in the periphery of pipe, because pipe is polygon, resistance to pressure is poor, when hydraulic pressure is higher, pipe easily deforms and breaks, and causes device to damage and work to stop.

(3) summary of the invention

Technical problem to be solved in the utility model provides the cold-slag slagging equipment of a kind of water pressure resistance height and reliable operation, good cooling results.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of cold-slag slagging equipment comprises frame, cold slag rotating cylinder, drive unit, and said cold slag rotating cylinder is made up of the pipe of closely alternate regular polygon, and each edge of said pipe is welded with round cooling.

Closely alternate orthohexagonal pipe is set in the said cold slag rotating cylinder, and the adjacent edge of adjacent pipe correspondence is a common steel plate, and corresponding edge is welded with common round cooling.

Said round cooling peripheral solder has and is the radially straight rib of radiation-like.

The thickness of said straight rib is 1/2 to 2/3 of steel plate thickness, and the straight rib of each round cooling peripheral solder is 4 to 12.

Said round cooling peripheral solder has the flight of same rotation direction.

The difference of the width of half of said steel plate width and said flight is no more than 1 millimeter, and the spacing of flight is more than or equal to its width, and pitch is between 0.5 to 2 times of its external diameter.

The diameter of said round cooling is between 20 millimeters to 200 millimeters, and the width of said steel plate is between 20 millimeters to 200 millimeters.

The number of said pipe is between 7 to 127.

Compare with background technology, cold-slag slagging equipment provided by the utility model has following advantage: 1, the utility model adopts and passes through cooling water in the round cooling, and therefore, the water pressure resistance ability of whole device is higher; 2, the straight rib or the flight of the utility model increase, increased the film-cooled heat of high-temperature material in cooling procedure, improved the heat exchange effect, cooldown rate is improved, therefore, under the situation of identical mass flow, installing needed rotating speed can descend significantly, make the device wearing and tearing littler, the life-span is longer, can also reduce the consumption of power simultaneously; If the flight structure, along with the rotation of cold slag rotating cylinder, material stirs between flight forward, like this, but said cold slag rotating cylinder also level be installed on the frame and use.

(5) specific embodiment

The utility model cold-slag slagging equipment comprises frame, cold slag rotating cylinder, drive unit, and cold slag rotating cylinder 1 is made up of the pipe 2 of closely alternate some regular polygons, and each edge of pipe is welded with a round cooling 3.Cold slag rotating cylinder is made up of tight alternate orthohexagonal pipe, and the adjacent edge of adjacent pipe correspondence is a common steel plate 4, and corresponding edge is welded with common round cooling.The round cooling peripheral solder has and is the radially straight rib 6 of radiation-like, and the thickness of straight rib is 1/2 to 2/3 of steel plate 4 thickness, and the straight rib of each round cooling peripheral solder is 4 to 12.Another embodiment is the form that adopts flight, that is, the round cooling peripheral solder has the flight 5 of same rotation direction, and the difference of the width of half of steel plate width and said flight is no more than 1 millimeter, the spacing of flight is more than or equal to its width, and pitch is between 0.5 to 2 times of its external diameter.The diameter of round cooling is between 20 millimeters to 200 millimeters, and the width of said steel plate is between 20 millimeters to 200 millimeters.The number of said pipe is between 7 to 127.

The manufacturing process of said structure is as follows: steel plate is divided into two of same widths, each round cooling is pressed Fig. 2 or three blocks of half such steel plates of equal angles shown in Figure 4 welding, then, corresponding straight rib is welded in the periphery that is shown in each round cooling by Fig. 2, and the straight rib in the welding is uniform radiation-like; Or press Fig. 3 and shown in Figure 4, in the scope of each 120 degree, flight is cut sheet and be welded on composition flight conveyor screw on the round cooling respectively; Then, by illustrated in figures 1 and 2, each adjacent half shape steel plate alignment to tight or weld, has so just been made cold slag rotating cylinder.

The course of work and the principle of this cold-slag slagging equipment are as follows: in the process of rolling, the cooling water in the round cooling cools down cinder by straight rib or flight, steel plate with contacting of cinder.For the structure of flight, then because each round cooling peripheral solder has the flight of same rotation direction, therefore, no matter cold slag rotating cylinder is the level installation or tilts to be installed on the frame that the cinder in the cold slag rotating cylinder all can roll to the other end from an end of pipe.For straight rib structure, cold slag rotating cylinder need tilt to be installed on the frame.

What need proposition is, the cold-slag slagging equipment that the utility model provides is not only applicable to the cinder cooling of boiler, and can be used in other field widely, the cooling of solid material all can be used this device, as, in process of production, be used for the cooling of chemical granule raw material titanium dioxide etc., cooling of cement granules or the like.
