Abstract

The utility model discloses a square burner block, which comprises a burner block body. The center of the burner block body is provided with a flaming device and the peripheral outline thereof is square. The outlet of the flaming device is in a trumpet shape. The burner block body is modified from the original round shape to the square shape, thus keeping the shape of the burner block body in line with the shape of a square insulation cotton around the burner block body, which increases the impermeability between the burner block and the insulation cotton, prevents the burner block from flaming to the steel plate on the insulation cotton, avoids the steel plate from being heated and deformed, prolongs the useful life of the steel plate and ensures the production security. In addition, a flaming port in the burner block is modified from the original cylinder shape to the trumpet shape, thus spreading the flaming area, shortening the flaming distance, preventing the flames from spraying onto the heated copper ingot, avoiding the copper ingot locally from being heated at high temperature, preventing the copper from falling due to oxidation, and ensuring the quality of the copper ingot.

Description

A kind of square burner block

Technical field

The utility model belongs to burner block, belongs to a kind of square burner block especially.

Technical background

The push-down heating furnace is when heating to copper strips, guarantee that the copper strips that is heated satisfies processing request, should ensure that the copper strips that is heated is heated evenly, general mode of heating is the flame heat method at present, employed raw material is generally oil or natural gas, thereby by nozzle burning after crude oil or the natural gas ejection is produced the purpose that heat reaches heating.

Existing push rod furnace burner block is circular burner block, as shown in Figure 1, 2, in the production application of reality, there is following drawback in this circle burner block 4: on the one hand, the structure because the heat-preservation cotton of burner block 1 periphery all is square, and burner block 1 is rounded, caused burner block 1 and heat-preservation cotton edge well to fit, always there is certain clearance, the flame that causes burner block 1 to spray burns the steel plate on the heat-preservation cotton along this gap, easily make the steel plate temperature distortion, cause steel plate to cave in the course of time most probably, cause security incident; On the other hand, circular burner block 1 has columnar bocca 2, causes the flame distance very long, and flare directly is sprayed onto on the copper ingot easily, causes copper ingot local heating too high, produces local copper oxidation and comes off, and influences copper ingot lustrous surface etc.In addition, the fastness of circular burner block 1 material is relatively poor, and production is caused great influence.

The utility model content

Technical problem to be solved in the utility model provides a kind of can fitting tightly with heat-preservation cotton and square burner block that flame distance is moderate.

The technical scheme of the utility model technical solution problem is: a kind of square burner block, a kind of square burner block, comprise the burner block body, the center position of burner block body is provided with flame device, the peripheral profile of described burner block body is square, and the exit of described flame device is horn-like.

Described flame device is the passage that is opened in burner block body center position, and the porch of passage is cylindrical, and the exit of passage is horn-like.

In the described burner block body a plurality of reinforcements are set, the upper end of reinforcement is welded on the lower face of header board, the header board of annular embeds the upper surface of burner block body, the plate face of header board and the upper surface of burner block body are on the horizontal plane, the circular hole that can supply passage to pass through is offered at the center of header board, the aperture of circular hole is greater than the size at feeder connection place, and header board is the fixing a plurality of screw rods that burner block body and furnace top insulation cotton are fitted tightly of being used for of welding upwards.

The shape of described reinforcement is herringbone, and the number of described reinforcement is 4, and the number of described screw rod is 4.

The utility model compared with prior art, described burner block body changes square structure into by original circle, make the profile of burner block body consistent with the shape of the square heat-preservation cotton of periphery, strengthened the seal between burner block and the heat-preservation cotton, can avoid the flame of burner block prolong and the steel plate on the heat-preservation cotton on, avoid the steel plate temperature distortion, not only prolonged the service life of steel plate, and guaranteed the security of producing.In addition, the inner bocca of burner block is made into tubaeform by original cylindrical shape, spread the flame area like this, shorten the flame distance, avoided flare directly to be sprayed onto on the copper ingot of heating, avoided copper ingot local heating too high, prevented that the copper oxidation from coming off, and guaranteed the quality of copper ingot.

Description of drawings

Fig. 1 is the prior art constructions schematic diagram;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is a structural representation of the present utility model;

Fig. 4 is the vertical view of Fig. 3.

In Fig. 3,4,3 is that burner block body, 4 is that header board, 5 reinforcements, 6 are that screw rod, 7 is that passage, 8 is that porch, 9 is the exit.

The specific embodiment

Below in conjunction with embodiment the utility model is done detailed explanation.

Shown in Fig. 3,4:

A kind of square burner block comprises burner block body 3, and the center position of burner block body 3 is provided with flame device, and the peripheral profile of described burner block body 3 is square, and the exit of described flame device is horn-like.Described flame device is the passage 7 that is opened in burner block body 3 center positions, and the porch 8 of passage 7 is cylindrical, and the exit 9 of passage 7 is horn-like.

A plurality of reinforcements 5 are set in the described burner block body 3, and the shape of reinforcement 5 is herringbone, and the number of reinforcement 5 is 4 in the utility model, and the upper end of reinforcement 5 is welded on the lower face of

header board

4, and 4 heat-blocking actions of header board prevent that the furnace top insulation cotton is overheated.The header board 4 of annular embeds the upper surface of burner block body 3, the plate face of header board 4 and the upper surface of burner block body 3 are on the horizontal plane, the circular hole 10 that can supply passage 7 to pass through is offered at the center of header board 4, the aperture of circular hole 10 is greater than the size of the porch 8 of passage 7, header board 4 is the fixing a plurality of screw rods 6 that burner block body 3 and furnace top insulation cotton are fitted tightly of being used for of welding upwards, and the number of screw rod 6 is 4.6 fixations of screw rod, the position of fixing whole burner block combines closely burner block and furnace top insulation cotton by screw rod 6.

As seen, described burner block body 3 changes square structure into by original circle, make the profile of burner block body 3 consistent with the shape of the square heat-preservation cotton of periphery, strengthened the seal between burner block and the heat-preservation cotton, can avoid the flame of burner block prolong and the steel plate on the heat-preservation cotton on, avoid the steel plate temperature distortion, not only prolonged the service life of steel plate, and guaranteed the security of producing.In addition, the inner bocca of burner block is made into tubaeform by original cylindrical shape, spread the flame area like this, shorten the flame distance, avoided flare directly to be sprayed onto on the copper ingot of heating, avoided copper ingot local heating too high, prevented that the copper oxidation from coming off, and guaranteed the quality of copper ingot.
