Description

Drag hook brick for furnace walls on two sides of waste incineration power generation boiler

Technical Field

The utility model relates to a msw incineration power generation boiler part especially relates to the hook brick is used to msw incineration power generation boiler both sides brickwork.

Background

In daily life of people, a large amount of garbage is inevitably generated. If the garbage is not effectively treated, the living environment of people can be greatly influenced, and even the health of people is threatened. At present, incineration is one of the main ways of disposing garbage, but in the process of incinerating garbage, not only secondary environmental pollution is caused, but also waste of resources and energy is caused. Therefore, in the garbage disposal, a mode of generating electricity by burning garbage can be adopted. In recent years, waste incineration power generation has attracted high national attention and attention as the best way of disposing domestic waste in a way of reduction, harmlessness and recycling.

The waste incineration power generation boiler is generally built by refractory bricks, drag hook bricks, refractory castable and the like, and the T-shaped drag hook part is placed at the opening of the existing drag hook brick (refer to figure 1) in the construction and maintenance of the boiler wall, so that the connection of the bricks is weak, the bricks are easy to break, and the boiler wall is not fixed firmly.

Hang the end and be connected with furnace roof hanger, the drag hook changes the brick body and pours in the work lining pouring material, general work lining design lower part is heavy pouring material upper portion and is the light pouring material, produce stress easily at light pouring material and heavy pouring material interface department, this stress produces the interact easily with the drag hook changes the brick body and produces stress concentration in brick body recess, when stress is greater than the stress that the brick body can bear, the drag hook changes the brick body and will break, and the recess on current drag hook commentaries on classics surface all is perpendicular to the axis of the brick body, the drag hook of this kind of structure changes and uses under high temperature environment, also easily breaks under the condition that has thermal stress concentration, thereby lead to the accident, cause the downtime to overhaul, influence normal production order.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome prior art not enough, provide a structural design science, difficult emergence stress concentration, it is strong to stress resistance, difficult cracked waste incineration power generation boiler both sides drag hook brick for brickwork.

For realizing the utility model provides the following technical scheme:

waste incineration power generation boiler both sides drag hook brick for brickwork mainly includes the cuboid brick body, the brick body is including hanging end section and anchor section, anchor section outer wall evenly sets up a plurality of sand grips and recess, be connected for the inclined plane between sand grip and the recess, sand grip and recess slope set up, the recess slope opposite direction on the adjacent both sides face of anchor section, hang end section center and still set up the slope that link up and hang end section top surface and bottom surface and hang the through-hole.

Furthermore, ribs are arranged in the centers of the side surfaces of the anchoring sections.

Furthermore, the height of the ribs is lower than that of the raised strips and higher than that of the grooves.

Furthermore, the inclined direction of the hanging through hole is obliquely and upwards arranged from the bottom surface to the top surface of the hanging end head section, and the inclined angle is 70-80 degrees.

Further, the inclination angle of the inclined plane is 30-50 degrees.

Further, the surface of the inclined surface is a smooth surface or a corrugated surface, preferably corrugated.

The utility model discloses an useful part:

firstly, the method comprises the following steps: the raised lines and the grooves are obliquely arranged, so that the grooves are prevented from being perpendicular to the brick body, the contact area between the brick body and the fixed castable is increased, the shearing resistance of the brick body is enhanced, and the influence of concentrated thermal stress can be resisted;

secondly, the method comprises the following steps: the arrangement of the ribs obviously improves the tensile strength and the bending strength of the brick body due to the reinforcing and drawing effects of the ribs, and the stress generated at the groove is blocked at the ribs and cannot be continuously transmitted, so that the drag hook with the structure is not easy to break;

thirdly, the method comprises the following steps: the inclination directions of the grooves on the two adjacent side surfaces of the anchoring section are opposite, so that the firmness between the brick body and the casting material can be further enhanced, and the transmission of stress is blocked;

fourthly: the existing T-shaped drag hook part is changed into a hanging through hole, so that the drag hook part is prevented from being broken.

Waste incineration power generation boiler both sides drag hook brick for brickwork mainly includes cuboid brick body 2, brick body 2 is including hanging tip section 2.1 and anchor section 2.2, anchor section 2.2 outer wall evenly sets up a plurality of sand grips 3 and recess 4, be connected for inclined plane 5 between sand grip 3 and the recess 4, sand grip 3 sets up with the 4 slope of recess, the recess 4 slope opposite direction on the adjacent both sides face of anchor section 3.3, hang tip section 2.1 center and still set up the slope that link up and hang tip section 2.1 top surface and bottom surface and hang through-hole 6. Set up sand grip 3 and the slope of recess 4, avoid the 4 perpendicular to brick bodies 2 in recess, increase the brick body 2 and the area of contact of fixed castables, strengthened the 2 anti-shear capacity of brick body, can resist the concentrated thermal stress influence, the 4 slope opposite directions of recess on the adjacent both sides face of anchor section 2.2 can further strengthen the firmness between the brick body 2 and the castables, the transmission of separation stress simultaneously.

Furthermore, a rib 7 is arranged at the center of the side surface of the anchoring section 2.2. Set up rib 7, because the reinforcement and the tractive effect of rib 7, the tensile rupture strength of the brick body 2 obviously improves, and the stress that produces in recess 4 department obtains the separation in rib 7 department and can not continue the transmission, so the difficult fracture that takes place of drag hook commentaries on classics of this kind of structure.

Further, the height of the ribs 7 is lower than that of the convex strips 3 and higher than that of the grooves 4.

Furthermore, the hanging through hole 6 is inclined upwards from the bottom surface to the top surface of the hanging end head section 2.1, and the inclination angle is 70-80 degrees. The existing T-shaped drag hook part 1 is changed into a hanging through hole 6 to prevent the drag hook part from being broken (refer to figure 3).

Further, the inclination angle of the inclined plane 5 is 30-50 degrees.

Further, the surface of the inclined surface 5 is a smooth surface or a corrugated surface, and is preferably corrugated, so that the contact area between the brick body 2 and the casting material can be increased.

This drag hook changes when using (refer to fig. 3) cooperation door shape drag hook 8, door shape drag hook 8 includes connecting rod 8.1 and sets up first hook portion 8.2 and the second hook portion 8.3 at connecting rod 8.1 both ends, first hook portion 8.2 is perpendicular with connecting rod 8.1, second hook portion 8.3 slope, inclination is unanimous with the inclination of hanging through-hole 6, insert second hook portion 8.3 in hanging through-hole 6 during the use, be connected first hook portion 8.2 and the stove outer covering can.

The present invention is not limited to the above-mentioned drag hook bricks for the two side walls of the waste incineration power generation boiler, and those skilled in the art can make various changes according to the above-mentioned embodiments, but any changes equivalent or similar to the present invention should be covered by the scope of the claims of the present invention.
