Description

Technical Field

[0001] The utility model belongs to the technical field of alloy plates, and particularly relates to an adjustable anti - detachment anti - abrasion alloy plate for a CFB boiler. Background Art

[0002] The water - cooled wall is the main heat - receiving part of the boiler. It consists of several rows of steel pipes distributed around the boiler furnace. The inside of it is filled with flowing water or steam, and it receives the heat of the flame in the boiler furnace from the outside, mainly absorbing the radiant heat of the high - temperature combustion products in the furnace. The working medium moves upward in it, is heated and evaporated. However, due to the relatively harsh working conditions in the CFB boiler furnace, and the high flow velocity and large concentration of flue gas and ash slag flow, during the use of traditional CFB boilers, the phenomenon of anti - abrasion alloy plate detachment often occurs. After a large number of anti - abrasion alloy plates fall off, local eddy currents will be generated, resulting in rapid wear areas, which are extremely likely to cause water - cooled wall wear, leakage, and even pipe explosion accidents, threatening the safe operation of the boiler. Content of the Utility Model

[0003] Aiming at the problems raised in the above - mentioned background art, the purpose of the present utility model is to provide an adjustable anti - detachment anti - abrasion alloy plate for a CFB boiler.

[0004] To achieve the above - mentioned technical purpose, the technical scheme adopted by the present utility model is as follows:

[0005] An adjustable anti - detachment anti - abrasion alloy plate for a CFB boiler, including an anti - abrasion alloy plate body. An anti - detachment device is installed on the left side of the anti - abrasion alloy plate body. An anti - detachment slot is provided on the right side of the anti - abrasion alloy plate body. Welding point slots are provided at both ends of the upper side of the anti - abrasion alloy plate body. Flow - guiding slots are provided at both ends of the lower side of the anti - abrasion alloy plate body.

[0006] Further defined, the anti - detachment device includes an anti - detachment column. The anti - detachment column and the anti - abrasion alloy plate body are integrally formed. The external dimension of the anti - detachment column is smaller than the internal dimension of the anti - detachment slot. Such a structural design facilitates the installation of the anti - detachment column on one anti - abrasion alloy plate body into the anti - detachment slot on another anti - abrasion alloy plate body during subsequent lapping, forming a wave - like overlapping structure like fish scales.

[0007] Further defined, the anti - detachment slot is arranged in a U - shaped structure. Such a structural design facilitates subsequent lapping and installation.

[0008] Further defined, a semi - circular slot is provided between the two welding point slots on the anti - abrasion alloy plate body. An arc - shaped slot is provided outside the welding point slot on the anti - abrasion alloy plate body. Such a structural design enables the combination of two arc - shaped slots to form a semi - circular slot after lapping and installation, facilitating subsequent installation.

[0009] Further defined, a chamfered arc is provided on the outer side of the wear-resistant alloy plate body in the diversion groove. Such a structural design can prevent the phenomenon of local wear.

[0010] The beneficial effects of the present utility model are as follows: The present utility model forms a wave-shaped fish-scale lap joint through the wear-resistant alloy plate body and fixes it by welding, improving the connection and fixing effect and preventing detachment. At the same time, after being installed in the CFB boiler, welding is carried out through the welding point groove, thereby playing a role in fixing and connecting the wear-resistant alloy plate body. Furthermore, through the installed wear-resistant alloy plate body, the wear of the water-cooled wall of the boiler can be effectively prevented, the detachment of the welding points and the wear-resistant alloy plate body can be prevented, and the use effect is improved.

[0016] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below with reference to the drawings and embodiments.

[0017] Embodiment 1, as Figure 1 and Figure 2 shown, an adjustable anti-detachment CFB boiler wear-resistant alloy plate, an anti-detachment device 2 is installed on the left side of the wear-resistant alloy plate body 1, an anti-detachment card slot 3 is provided on the right side of the wear-resistant alloy plate body 1, welding point grooves 4 are provided at both ends of the upper side of the wear-resistant alloy plate body 1, and diversion grooves 5 are provided at both ends of the lower side of the wear-resistant alloy plate body 1.

[0018] In this embodiment, during installation, only the anti-wear alloy plate body 1 needs to be installed. Since the anti-disengagement devices 2 and anti-disengagement slots 3 are respectively arranged on both sides of the anti-wear alloy plate body 1, during the installation process, only the anti-disengagement device 2 on one anti-wear alloy plate body 1 needs to be spliced into the anti-disengagement slot 3 on another anti-wear alloy plate body 1, and then it is fixed by welding. During the welding process, the anti-disengagement device 2 and the anti-disengagement slot 3 can play a limiting role, thereby ensuring the installation of the anti-wear alloy plate body 1. After installing multiple alloy anti-wear plates 1, they only need to be installed into the CFB boiler. When the anti-wear plate needs to be installed, it is welded through the solder joint groove 4 to connect and fix the anti-wear alloy plate body 1.

[0019] During the use process, the ash accumulation in the CFB boiler is diverted through the diversion groove 5, and the anti-wear alloy plate body 1 with the wave-like fish-scale lap joint can effectively prevent the water-cooled wall from being worn.

[0020] Embodiment 2, as Figure 1 shown, this embodiment adds the following structure on the basis of Embodiment 1. The anti-disengagement device 2 includes an anti-disengagement column 6. The anti-disengagement column 6 and the anti-wear alloy plate body 1 are integrally formed. The external dimension of the anti-disengagement column 6 is smaller than the internal dimension of the anti-disengagement slot 3. Such a structural design facilitates the installation of the anti-disengagement column 6 on one anti-wear alloy plate body 1 into the anti-disengagement slot 3 on another anti-wear alloy plate body 1 during subsequent lapping to form a wave-like fish-scale lap joint.

[0021] In this embodiment, during use, the anti-disengagement column 6 on one anti-wear alloy plate body 1 is installed into the anti-disengagement slot 3 on another anti-wear alloy plate body 1 to form a wave-like fish-scale lap joint, and it is fixed by welding to improve the connection and fixing effect and prevent detachment.

[0022] Embodiment 3, as Figure 1 shown, this embodiment adds the following structure on the basis of Embodiment 1. The anti-disengagement slot 3 is arranged in a U-shaped structure.

[0023] In this embodiment, during use, due to the anti-disengagement slot 3 arranged in a U-shaped structure, it is convenient for the quick installation and lapping use of the anti-disengagement device 2, improving the installation efficiency.

[0024] Embodiment 4, as Figure 1 shown, this embodiment adds the following structure on the basis of Embodiment 1. The anti-wear alloy plate body 1 is provided with a semi-circular groove 7 between the solder joint grooves 4 at both ends, and an arc groove 8 is arranged outside the solder joint groove 4.

[0025] In this embodiment, during installation, through the semi-circular groove 7 and the semi-circular groove 7 formed by combining two arc grooves 8 after lapping installation, it is convenient to install and place pipes for use.

[0026] Example 5, as Figure 2 shown, this example adds the following structure on the basis of Example 1. The anti-wear alloy plate body 1 is provided with a chamfered arc 9 on the outside of the diversion groove 5. Such a structural design can prevent the phenomenon of local wear from occurring.

[0027] In this example, through the smooth transition of the chamfered arc 9, the phenomenon of local wear can be prevented from occurring.
