Technical Field

[0001] The utility model relates to the relevant field of vertical cooling kilns, in particular to a material discharge device of a vertical cooling kiln. Background Art

[0002] Under the guidance of the national overall policy of energy conservation and emission reduction, in order to significantly reduce the use of industrial energy, the steel industry attaches great importance to taking relevant measures to optimize the production process and control the energy consumption of the process to reduce the energy consumption of the enterprise. Among them, the recovery and utilization of waste heat in each production link has become one of the most effective ways to save energy and reduce emissions. In order to be able to more effectively recover the waste heat of hot sintered ore, the vertical cooling kiln recovery method is currently generally adopted, which solves the problem of low waste heat recovery efficiency caused by air leakage in the previous sintered ore cooling (ring cooling, belt cooling) equipment, thereby being able to recover the waste heat of hot sintered ore to the greatest extent.

[0003] The Chinese patent with the patent number CN201420038482.5 discloses "A lower hopper of a vertical cooling kiln". Through the arrangement of fin plates and grooves, and the inner lining plate formed by splicing small-area rectangular sub-lining plates, the friction between the base plate and the material is reduced, solving the technical problems of the existing lower hopper having poor wear resistance, short service life and inconvenient maintenance and replacement, thereby ensuring the effect of waste heat recovery and the stable operation of the waste heat recovery system;

[0004] This structure has certain advantages, but still has some shortcomings:

[0005] During the use of this structure, when the material particles are large, the material cannot be accumulated on the fin plate, and thus the friction between the material and the hopper base plate cannot be reduced. At the same time, regardless of whether the material is accumulated on the fin plate, the inner surface of the fin plate is susceptible to friction. When a large area of ​​the fin plate is damaged by friction, the corresponding large area of ​​the sub-liner needs to be disassembled and replaced, which is labor-intensive and increases the difficulty of maintenance. Utility Model Content

[0013] As a further solution of the utility model, the balls and spacers are provided in multiple groups, and the balls and spacers are distributed adjacent to each other, so as to avoid movement obstruction between two adjacent groups of balls under the action of the circular support ring. The spacers are provided to enable the balls to roll smoothly.

[0014] As a further solution of the utility model, both ends of the spacer are arc-shaped, which are adapted to the shape of the ball.

[0015] As a further solution of the utility model, the diameter of the positioning block is larger than the diameter of the ball. The positioning block is in contact with the inner guide plate and the positioning ring, so that the protective element is stably installed inside the inner guide plate and provides space for the ball to roll.

[0016] As a further solution of the utility model, the bottom end of the positioning ring is arc-shaped, providing an adaptable space for the rolling of the ball.

[0017] As a further solution of the utility model, the outer side of the inner guide plate fits with the inner side of the connecting groove. By placing the inner guide plate in the connecting groove, it is convenient to subsequently lock and fix the inner guide plate to the base with bolts, thereby improving stability during installation.

[0018] As a further solution of the utility model, the support ring is made of a heat-resistant alloy, and has the advantages of stable structure and excellent mechanical, material and chemical properties under high-temperature use environment conditions.

[0021] 1. In the utility model, the connection groove is provided to enhance the stability of the inner guide plate and the base bolt during installation, and the installation of the protective member allows the material to be discharged by relying on the rolling of the ball, thereby reducing the friction between the material and the discharge device. Moreover, when the ball is worn over a large area, the corresponding annular protective member can be disassembled to achieve large-scale and rapid disassembly, thereby improving the convenience of maintenance.

[0022] 2. In the utility model, a protective member is arranged inside the inner guide plate, and a positioning block with a larger diameter is used to fix the positioning block, so that the upper and lower ends of the positioning block are fixed by the inner guide plate and the positioning ring, thereby increasing the rolling space for the ball with a smaller diameter, and realizing the rapid installation and removal of the protective member.
