Description

Technical Field

[0001] This utility model belongs to the field of dry quenching coke oven technology, and in particular relates to a reinforcement mechanism for the brackets of a dry quenching coke oven. Background Technology

[0002] The coking industry is an important energy conversion industry for coal resource processing and utilization. As a key support structure that bears the weight of coke, the dry quenching coke oven support is subjected to high temperature (600-800℃) and cyclic impact load for a long time. The dry quenching oven support is under harsh conditions such as long-term high temperature load, frequent and drastic temperature changes, chemical erosion, and scouring and wear of coke dust. Among these, thermal stress and compressive stress are the main causes of its damage.

[0003] Traditional reinforcement methods mainly employ welding reinforcing ribs or external clamps, welding radially distributed ribs to the surface of the bracket body to improve bending strength, or installing steel ring clamps at the base of the bracket and locking them with bolts. This structure requires construction after the coke oven has been shut down and cooled, first cleaning the oxide layer on the surface of the bracket, and then positioning and welding or assembling the clamps. Its main body still relies on rigid constraints. Therefore, we provide a dry quenching coke oven bracket reinforcement mechanism to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model is a reinforcement mechanism for the support bracket of a dry quenching coke oven, including a support bracket body 1. The support bracket body 1 is installed on an external support frame. Two arc-shaped support plates 2 are installed on the side of the support bracket body 1. The two arc-shaped support plates 2 are flush with the bottom of the support bracket body 1 and are located on the external support frame. During the installation process, the two arc-shaped support plates 2 are first spliced ​​on the side of the support bracket body 1. The two arc-shaped support plates 2 are combined to form a support ring and set on the side of the support bracket body 1. A steel frame support group 3 is detachably installed on the side of the support bracket body 1.

[0026] Specifically, the steel frame support group 3 includes two arc-shaped limiting plates 301. The two arc-shaped limiting plates 301 are combined to form a limiting ring and installed on the side of the corbel body 1. Several oblique reinforcing rods 302 are installed at the bottom of the arc-shaped limiting plates 301. The oblique reinforcing rods 302 are connected to the arc-shaped limiting plates 301 by bolts 303. The two limiting plates 301 are located above the arc-shaped support plate 2, and the bottom of the oblique reinforcing rods 302 is located at the top of the arc-shaped support plate 2.

[0027] Furthermore, a connecting rod 4 is rotatably provided on the top of the arc-shaped support plate 2, and a positioning threaded rod 5 that slides with the corresponding arc-shaped limiting plate 301 is fixedly provided on the top of the connecting rod 4;

[0028] The top of the positioning threaded rod 5 is fixedly provided with a plug rod 6, and the top of the arc-shaped support plate 2 is fixedly provided with a guide rod 7 that slides with the arc-shaped limiting plate 301. Before assembly, the arc-shaped support plate 2 is plugged into the guide rod 7 until the bottom of the arc-shaped limiting plate 301 is in contact with the top of the connecting rod 4.

[0029] Furthermore, two arc-shaped positioning plates 9 are detachably installed on the side of the bracket body 1. The two arc-shaped positioning plates 9 combine to form a positioning ring and are set on the side of the bracket body 1. The arc-shaped positioning plates 9 are located above the arc-shaped limiting plate 301. The arc-shaped limiting plate 301 is inserted into the insertion rod 6 and the guide rod 7. Then, the insertion rod 6 is rotated to drive the positioning threaded rod 5 to rotate, and the arc-shaped positioning plate 9 moves downward. The position of the arc-shaped positioning plate 9 is adjusted according to the actual height of the bracket body 1 to limit the position of the arc-shaped positioning plate 9, thereby strengthening the fixation of the bracket body 1. The inner walls of the arc-shaped support plate 2, the arc-shaped limiting plate 301, and the arc-shaped positioning plate 9 are all fixedly provided with Several elastic buffers 8, the elastic buffers 8 on the inner walls of the arc-shaped support plate 2, the arc-shaped limiting plate 301 and the arc-shaped positioning plate 9 absorb thermal stress vibration. The bracket body 1 generates radial thermal expansion (about 1.5 to 3 mm) under the high temperature conditions of the dry quenching coke oven (usually >600℃). The elastic buffers 8 use high temperature resistant graphite composite gaskets (compression rate ≥15%), which absorb the expansion displacement through their own compression, and avoid deformation and cracking of the arc-shaped support plate 2 and the arc-shaped limiting plate 301 due to rigid constraints. The instantaneous impact generated by the falling coke in the coke oven, the porous honeycomb structure of the elastic buffers 8, converts the vibration wave into micro-deformation heat energy, thereby improving the vibration attenuation rate.

[0032] The working principle of this utility model is as follows: two arc-shaped support plates 2 are combined into a support ring and fitted onto the bottom periphery of the bracket body 1 so that it is flush with the external support frame. Then, two arc-shaped limiting plates 301 are combined into a limiting ring and fitted onto the middle periphery of the bracket body 1 so that the inclined reinforcing rod 302 at the bottom of the arc-shaped limiting plate 301 falls onto the top of the arc-shaped support plate 2. The connection between the inclined reinforcing rod 302 and the arc-shaped limiting plate 301 is fixed by bolts 303, and the position of the connecting plate 304 is fixed by fasteners.
