Technical Field
The utility model relates to a boiler, especially hanging screen bottom pouring material abrasionproof elbow that hanging screen conduit saddle was used in boiler furnace.
Background
The boiler is the equipment of common use in the industrial production, hang screen bottom pouring material elbow department often drops in the boiler furnace, the pouring material is mended and is fallen again, very easily take place the wearing and tearing and leak, cause hang screen pipe elbow because of wearing and tearing leak and blowing out the stove accident, make the reduction of the rate of utilization of boiler, the production efficiency and the result of use and the life of boiler have been influenced greatly, consequently, how to solve the pouring material and drop, prevent the blowing out accident, guarantee boiler availability and life, become the technological problem that needs to solve in the present boiler uses urgently.
SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming prior art's defect, the utility model aims at providing a hanging screen bottom pouring material abrasionproof elbow in boiler furnace can effectively solve and prevent droing of pouring material, improves boiler availability factor and life's problem.
The technical scheme of the utility model provides a, a hanging screen bottom pouring material abrasionproof elbow in boiler furnace, including the abrasionproof elbow body, the concrete stopping is equipped with in the abrasionproof elbow body, is equipped with the reinforcing bar in the stopping, and the abrasionproof elbow body dress is in furnace hanging screen below, and the corner is equipped with the arc recess under the abrasionproof elbow body, and the welding has the wear-resisting metal cambered plate unanimous with the arc recess in the arc recess, the outer cambered surface and the abrasionproof elbow body outer wall parallel and level of wear-resisting metal cambered plate.
The utility model discloses simple structure, novel unique, installation convenient to use, it is effectual, can effectively prevent droing of hanging screen bottom pouring material in the boiler furnace, prevent the blowing out accident, guarantee the availability factor and the life of boiler, economy and social are showing.

Fig. 2 is an enlarged structure view of the wear-resistant metal arc panel of the present invention.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
By figure 1, 2 shown, the utility model relates to a hanging shield bottom pouring material abrasionproof elbow in boiler furnace, including abrasionproof elbow body 1, concrete stopping 2 is equipped with in the abrasionproof elbow body 1, is equipped with reinforcing bar 3 in the stopping 2, and the abrasionproof elbow body 1 dress is in 5 below of furnace hanging shield, and 1 lower corner of abrasionproof elbow body is equipped with arc recess 6, and the welding has the wear-resisting metal cambered plate 4 unanimous with the arc recess in the arc recess 6, and wear-resisting metal cambered plate 4's outer cambered surface and 1 outer wall parallel and level of abrasionproof elbow body.
In order to ensure the use effect and the use convenience, welding position inclined planes 4-1 are arranged at the two end parts of the wear-resistant metal arc panel 4;
the wear-resistant metal arc panel 4 is made of Cr25Ni20The curved cambered surface body is made of alloy steel, the upper body of the curved cambered surface body is a straight body, the lower body of the curved cambered surface body is an integral structure formed by connecting the cambered surface bodies, the length of the straight body part 4-2 of the upper body is 100mm, the length is convenient for being assembled with a hanging screen, the diameter of the curved cambered surface part 4-3 is 42-60mm, and an angle of 90 degrees is formed between one end of the straight body part, which is connected with the elbow, and the other end of the elbow.
The utility model discloses when using, replace former anti-abrasion elbow with abrasionproof elbow body 1, weld wear-resisting metal cambered plate 4 in arc recess 6 with CHS402 Atlantic welding rod, and wear into the parallel and level with the extrados of wear-resisting metal cambered plate 4 and the outer wall of abrasionproof elbow body 1, very convenient and fast, and through installing on the spot and using, the effect is very good, through 2018-2019 in Xinjiang and Shanxi respectively to 2 160 ton boilers, 2 320 ton boilers, 2 260 ton boilers reform transform, the check of blowing out after boiler operation 100 days, the castable does not drop, whole hanging screen pipe does not have any wearing and tearing sign, blowing out has not appeared yet, the experiment has obtained very big success, compared with the prior art, following outstanding useful technological effect has:
1. the service cycle of the boiler can be controlled and controlled according to production requirements. The passive situation that the boiler runs for less than a month before the anti-abrasion modification is completely twisted.
2. The maintenance cost is saved. Taking a 260-ton boiler as an example, the direct cost of blowing out and overhauling of each abrasion pipe explosion comprises the following steps: the cost for building and dismantling the hearth frame is 5 ten thousand yuan, the construction cost for replacing the pipe is 6 ten thousand yuan, and the cost for recovering and starting the boiler is 10 ten thousand yuan. The direct loss of 21 ten thousand yuan per blow-out is calculated for 6 times per one year according to pipe explosion, the direct loss of each furnace exceeds 120 ten thousand yuan, and after the anti-abrasion elbow is used in a modified mode, large abrasion is not generated within 3 years, blow-out is not generated, and maintenance cost and production cost are greatly saved.
3. The long-period operation of the boiler is ensured, and the coal and electricity are saved. The boiler can run under the condition of full capacity, and the coal consumption and the power consumption are close to the design level.
4. The heat source guarantee is provided for the post-system production of a heat supply unit, so that the post-system production is stable and reliable, the innovation on boiler equipment is realized, and the economic and social benefits are remarkable.
