Description

Vertical circular kiln siphon type discharge port channel masonry structure

Technical Field

The utility model belongs to the technical field of stove structure masonry, concretely relates to vertical circular stove hydrocone type discharge port passageway masonry structure.

Background

The vertical circular kiln is used for an Osmant furnace, a shaft furnace and the like for smelting heavy metals such as copper, nickel and the like, and the siphon-type discharge port of the vertical circular kiln is mainly used for a discharge port for discharging metal melt or slag in the heavy metal smelting process. The melt discharge port is a key part, and due to high use frequency and large internal and external temperature difference, the discharge port is a key control object for safe operation of the metallurgical furnace. Because the circular masonry structure of vertical circumference kiln, the hydrocone type discharge port builds the degree of difficulty greatly, combines not well with the circumference, and the trompil size is too big easily to cause the bulk strength to reduce on the circumference brickwork, produces the gap, takes place the risk of fuse-element seepage, consequently vertical circumference kiln discharge port all adopts the inline type. The vertical circumferential kiln direct-discharge outlet has the defects of easy leakage, easy fluctuation of melt surface, high valuable metal content in slag and the like. The rectangle passageway of placing vertical circumference brickwork in has the lower part brick body inflation to arch up under high temperature, and the upper portion brick body sinks, and the inside inflation of both sides brick body makes the brick body produce the risk that the gap leads to the high temperature fuse-element seepage.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a vertical circular kiln hydrocone type discharge port passageway masonry structure to place the rectangle passageway of vertical circumference brickwork in the solution and have the lower part brick body inflation to arch up under high temperature, the upper portion brick body sinks, the inside inflation of both sides brick body makes the brick body produce the problem that the gap leads to the high temperature fuse-element seepage.

In order to meet the purpose, the utility model discloses the technical scheme who takes does:

the utility model provides a vertical circular kiln hydrocone type discharge port passageway masonry structure, includes vertical circular kiln hydrocone type discharge port, the bottom upper surface of discharge port department is built by laying bricks or stones has the flat arch of passageway lower part, the flat arch of passageway lower part upper portion both sides are built by laying bricks or stones has the passageway side wall, two passageway side wall intermediate position is the passageway, the flat arch of passageway upper portion is built by laying bricks or stones on passageway side wall upper portion, the flat arch of upper portion is hugged closely with the upper portion brick body of discharge port department.

Preferably, the side wall of the channel is built by long standard bricks, and the side wall of the channel and the furnace body bricks are constructed by staggered joint biting.

Preferably, the first layer of bricks of the channel side wall is embedded into the flat arch at the lower part of the channel.

The utility model has the advantages that:

(1) The channel has the advantages of tight contact with the vertical circumferential furnace body and the water cooling piece, furnace bottom floating prevention, loosening prevention of the circumferential masonry at the discharge port, difficulty in leakage in the production process and guarantee of the discharge safety of the melt of the metallurgical furnace.

(2) The utility model discloses a lower part adopts the flat arch structure, can compress tightly the lower part circumference barrel brick body, can prevent to encircle on the brick body of passageway lower part, the passageway both sides are built by laying bricks or stones with long standard brick staggered joint stinging stubble, and stagger with furnace body water jacket seam, prevent that the fuse-element seepage from scaling down the water jacket, and the flat arch of side wall first layer brick embedding lower part, prevent that the side wall from inside inflation deformation production gap leads to the fuse-element seepage under circumference brickwork inflation extrusion effect, passageway upper portion adopts the flat arch to build the structure, can prevent that the upper portion brick body from sinking.

Drawings

FIG. 1 is a schematic view of the present invention;

in the figure: 1. a flat arch at the lower part of the channel; 2. a channel side wall; 3. the upper part of the channel is arched flatly.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and working principles:

the channel masonry structure of the siphon type discharge port of the vertical circular furnace shown in the figure 1 comprises the siphon type discharge port of the vertical circular furnace, a channel lower flat arch 1 is masonry-arranged on the upper surface of the bottom of the discharge port, channel side walls 2 are masonry-arranged on two sides of the upper portion of the channel lower flat arch 1, the middle positions of the two channel side walls 2 are channels, a channel upper flat arch 3 is masonry-arranged on the upper portion of the channel side walls 2, and the upper flat arch 3 is tightly attached to an upper brick body at the discharge port. The channel side wall 2 is built by long standard bricks, and the channel side wall 2 and the furnace body bricks are constructed by staggered joint and stubble biting. The first layer of bricks of the channel side wall 2 is embedded in the channel lower flat arch 1.

When the building is carried out, firstly, a channel lower flat arch 1 is built on the upper surface of the bottom of a siphon type discharge port of a vertical circular furnace, a lower circumferential barrel brick body can be pressed, channel side walls 2 with channels left in the middle are built on two sides of the upper part of the lower flat arch 1, the channel side walls 2 are built by long standard bricks, the channel side walls 2 and furnace body bricks are staggered and embedded in stubbles, the strength is ensured, the channel side walls are staggered with furnace body water jacket joints, a water jacket is prevented from being damaged by melt leakage and burning, a first layer of bricks of the channel side walls are embedded into the lower flat arch, the side walls are prevented from expanding and deforming inwards under the expansion and extrusion action of the circumferential brickworks to generate gaps to cause melt leakage, and the channel upper flat arch and the circumferential brickworks on two sides are built; the upper flat arch 3 of the channel is built on the upper part of the channel side wall 2, and the upper flat arch 3 is tightly attached to the upper brick body at the discharge outlet, so that the upper brick body can be prevented from sinking.

When the utility model discloses a discharge port passageway of building by laying bricks or stones uses, have with vertical circumference furnace body and water-cooling spare contact tight, prevent that the stove bottom from arching purpose such as showy, prevent simultaneously that it is not hard up to put exit circumference brickwork, advantages such as the passageway long service life of building by laying bricks or stones, also difficult seepage in the production process guarantees the advantage that metallurgical stove fuse-element discharged safety. The channel has the advantages that the expansion and upwarp of the lower brick body and the sinking of the upper brick body do not exist at high temperature, meanwhile, the brick bodies on the two sides are not suitable to be expanded inwards under the action of the channel side wall 2, and the problem that the brick bodies generate gaps to cause leakage of high-temperature melt is solved.
