Technical Field
[0001] The utility model relates to a feed hopper bracket structure of a pellet ring cooler in a steel plant, and more specifically discloses a bracket structure of a ring cooler. Background Technique
[0002] The 248㎡ blast ring pellet cooler (hereinafter referred to as the ring cooler) is one of the main equipment in the engineering design of metallurgical pellet plants. It is used to cool the pellet ore discharged from the rotary kiln at about 1250℃. The design specifications of the pellet ring cooler in the iron-making plant of Zhanjiang Iron and Steel are as follows: the effective cooling area is 248㎡, the maximum material handling capacity is 700t / h, the normal capacity is 630t / h, the effective cooling time is 30 - 120min, and the time required for one revolution is 35.7 - 142.8mmin. It adopts two sets of motor - reducer - open gear - pin gear drive forms. This ring cooler was officially put into production in September 2009.
[0003] There are no rib plate retaining edges on the upper side and bottom of the refractory bracket of the ring cooler feed hopper (see Figure 4 ). Since the material level in the ring cooler feed hopper is relatively high, the material from the rotary kiln drops into the ring cooler feed hopper, with a drop height of about 10 meters. The material directly flushes onto the upper part of the bracket. The original bracket has no rib plate retaining edge, resulting in the extremely easy detachment of the refractory cast on the bracket. The bracket body is directly exposed to the high-temperature pellets. Under harsh working conditions, the bracket is extremely easy to oxidize and burn, and high-temperature deformation and bracket detachment occur. Content of the Utility Model

One side of each circular hole is welded and fixed with a sleeve ring. The outside of the sleeve ring has an external thread, and the inside of the sleeve ring has an internal thread. The center of the sleeve ring coincides with the center of the circular hole. A threaded rod is arranged inside the circular hole and the sleeve ring. One end of the threaded rod is welded and fixed with a cap, and the inside of the cap has a thread.
[0006] Furthermore, the left side of the lower surface of the cross plate is welded and fixed with a side plate in the front - rear direction, and the right side of the side plate contacts the vertical plate, and the left side of the side plate contacts the right side of the concave plate.
[0007] Further, a connecting plate is fixedly connected above the right side of the support plate close to the cross plate.
[0008] Further, a trapezoidal plate is fixedly connected between the support plate and the rib plate retaining edge. There are two trapezoidal plates in total, and the lower surfaces of the two trapezoidal plates are fixed to the upper part of the cross plate.
[0009] Further, the cap is located outside the collar, and the cap is threadedly connected to the collar.
[0010] Further, the threaded rod is matched with the internal thread; the external thread is matched with the thread wire.
