Abstract

An improved steel slag tank belongs to the technical field of steel making equipment and has high strength, fine safety, easy manufacturing and low manufacturing cost. The improved steel slag tank comprises a tank body, trunnions and a tipping device, wherein the tank body is a polygon cone formed by welding a plurality of trapezoidal steel plates, the large end of the cone is an opening of the tank body while the small end is the bottom end of the tank body, the bottom of the tank is mounted on the inner side of the bottom end, outer walls of two sides of the opening of the tank body are fixedly connected with a trunnion base which is connected with a main vertical rib plate via a pivot, two sides of the trunnion base are provided with reinforcing vertical rib plates connected with the trunnion base and the outer walls of the tank body, the outer walls of the tank body are provided with horizontal reinforcing ribs surrounding the tank body, and the horizontal reinforcing ribs are closely fixedly connected with the outer walls of the tank body. The trunnion base and a main structural steel plate of the tank body are integrally stably fixed, thereby being capable of guaranteeing using safety and preventing loosening of the trunnions when stressed. The tank body is processed by utilizing the welding technique, is convenient in construction, reduces manufacturing difficulty without manufacturing molds, greatly shortens manufacturing period and greatly reduces manufacturing cost.

Description

A kind of improved steel slag tank

Technical field

The utility model relates to a kind of steel slag tank of making steel usefulness, belongs to the steelmaking equipment technical field.

Background technology

Now the steel industry steelworks slag ladle that is used for holding slag is commonly cast structure, and gudgeon is cast as one with tank body for processing back earlier, after casting is finished the part is processed, and tipple is installed again.

Existing slag ladle exists that subject matter has the manufacture difficulty height, the cycle is long, cost is high, work-ing life is short, poor stability, reparation difficulty etc., and is as follows in detail:

1. because deadweight is bigger, be that example weighs 55 tons with 33 cubes, the filling wall is thinner with respect to this part, has only 95 millimeters, so the casting difficulty, the scrap rate height have only for the less unit of number can make, and cost is higher, and fabrication cycle is long.

2. after manufacturing was finished, the part needed machining, because the tank body size is bigger, and processing difficulties, and have only the bigger lathe of specification just to have the ability to process, processing charges is higher.

3. security is relatively poor, because fixedly the metal structure of gudgeon is a cast structure, its intensity is difficult for assurance, and security incident such as easily rupture, slag leaks.

4. because tank body is a foundry goods, organize eakiness, when bearing higher temperature variation, ftracture easily, work-ing life is shorter, repairs difficulty.

Summary of the invention

The utility model wants the technical solution problem to provide a kind of defective that overcomes prior art, has intensity height, security is good, easy to manufacture, manufacturing cost is low improved steel slag tank.

The technical scheme that solves the problems of the technologies described above is:

A kind of improved steel slag tank, it is made up of tank body, gudgeon, tipple, its improvement is, the polygonal pyramid body of tank body for being welded to form by the trapezoidal steel plate of polylith, the big end of centrum is the tank body opening, small end is the bottom of tank body, the jar end, be installed in the inboard, bottom, on the outer wall of tank body opening both sides, be fixedly connected with trunnion seat, trunnion seat is connected by bearing pin with main vertical rib plate, there is the reinforcement vertical rib plate of engaging lug axle bed and tank wall the both sides of described trunnion seat, and the horizontal stiffener around tank body is arranged on tank wall, and they are closely fixedlyed connected with tank wall.

Above-mentioned improved steel slag tank, described horizontal stiffener are more than 3 roads.

Adopt the steel slag tank of this structure, tank body is spliced by the trapezoidal steel plate of polylith, and structural strength height, security are good; Trunnion seat and tank body main structure steel plate are welded as a firm integral body, can guarantee the safety used to prevent gudgeon slippage when stressed; Weldprocedure is adopted in tank body processing, easy construction, and the difficulty that reduces to make has the general unit of Weldability just can make, and need not make mould, and fabrication cycle shortens greatly, and manufacturing cost significantly reduces.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the side-view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1.

Mark is as follows among the figure: gudgeon 1, bearing pin 2, trunnion seat 3, reinforcement vertical rib plate 4, tank body 5, tipple 6,

horizontal stiffener

7,8,9,10,11.

Embodiment

Show among the figure, it is polygonal pyramid body structure (as eight pyramids, hecaprismo body, ten pyramids) that tank body changes traditional circular configuration, tank body 5 adopts organizes the higher rolled sheet material of closely knit intensity, tank body 5 is spliced by the trapezoidal steel plate of polylith, it during splicing easy construction, at first be inverted, weld the interface section, and then upset, be shaped as up big and down small positive multi-pyramid after the upset, thus the difficulty that reduces to make, there is the general unit of Weldability just can make, need not make mould, fabrication cycle shortens greatly, and manufacturing cost significantly reduces.

Gudgeon 1 of the present utility model and trunnion seat 3 are before welding with tank body 5, gudgeon 1 is pre-loaded into trunnion seat 3, and then welds with tank body 5 general assemblies.In the position perforate of tank body 5 correspondences, trunnion seat 3 is embedded among the main tank body 5.This kind structure can prevent gudgeon 1 slippage when stressed, and the reinforcement vertical rib plate 4 that two blocks of above-below directions are arranged in the both sides of trunnion seat 3, increase the bearing pin 2 of a shrink-fit again, thereby make trunnion seat 3 and reinforcement vertical rib plate 4, the tank body 5 main structure steel plates of both sides be combined into a firm integral body, the length that increases stressed weld seam can guarantee the safety used.Gudgeon 1 and trunnion seat 3 are forging, do flaw detection before the installation.

The of the present utility model jar of end, keep corresponding distance for putting into apart from bottommost from top to bottom, and the generation of the phenomenon that breaks off the base in can preventing to use guarantees the safety of using.

In order to guarantee the globality of tank body 5, prevent cracking, present embodiment has five road

horizontal stiffeners

7,8,9,10,11 altogether in the horizontal direction.The per pass horizontal stiffener is welded to connect by four steel plate bars by bending forms the corner angle of the corresponding tank body in bending place.For proof strength, horizontal stiffener does not have weld seam in the corner angle position of tank body.

Jar end, is the part of connecting rod base for processing in advance of tipple 6 fixedly, at the bottom of being welded on jar, irritates and need not reprocess after integral manufacturing finishes, and reduces by a procedure, can reduce cost of manufacture.

The utility model can be obtained following effect after implementing:

1, can reduce cost of manufacture, cost of equipment reduces;

2, the manufacturing cycle can be shortened;

3, increase the service life and reach more than the twice, can reduce use cost;

4, the security of can raising equipment using;

5, because tank body is the plane steel plate formation, it is convenient to repair

6, after tank body was scrapped, forging gudgeon that cost is higher and trunnion seat were disassembled after simple processing is reusable, reduce the expense of making once more.
