Abstract
Description
Technical Field
[0001] This utility model relates to a static material feeder drop column, belonging to the technical field of static material feeders in the metallurgical industry. Background Technology
[0002] The static charge feeder is an essential piece of equipment for a blast furnace. Each static charge feeder head has a drop column installed above the discharge port. These drop columns are vulnerable parts, serving three main functions: first, to protect the static charge feeder head from wear; severe wear would lead to difficult repairs or even complete replacement; second, to act as a buffer, reducing the impact of the material falling from the conveyor belt on the static charge feeder head, thus effectively protecting the head and liner; and third, to prevent the material from clogging the central discharge port due to concentrated material drop points, which can be evenly distributed to the four discharge ports by the drop columns.
[0003] The existing static distributor drop column is made of cast steel alloy wear-resistant material, which has a complex structure, short service life and high purchase price. It cannot be replaced periodically, causing wear on the static distributor head body and liner. In order to solve these problems, it is necessary to provide a new type of static distributor drop column device. Utility Model Content
[0004] The purpose of this invention is to provide a static material feeder drop column with a simple structure, low manufacturing cost, long service life, reduced maintenance personnel's work frequency, and to solve the problems existing in the background technology.
[0005] The technical solution of this utility model is:
[0006] A static material feeder discharge column includes a channel steel, angle iron, connecting round steel, ceramic blocks, and mounting holes. The length of the channel steel matches the discharge hopper of the static material feeder. Both ends of the channel steel are fixed to an angle iron. Each angle iron has a mounting hole. Several ceramic blocks are arranged along the length of the channel steel. The ceramic blocks are connected together by connecting round steel.
[0007] The channel steel contains several rectangular ceramic blocks along its length, which are attached to the channel steel using AB glue.
[0008] The channel steel has a central hole in the middle of several ceramic blocks along its length that matches the connecting round steel.
[0009] A fixed round steel bar is provided on each side of the channel steel, and the two ends of each fixed round steel bar are fixed to the angle irons at both ends of the channel steel.
[0010] The mounting holes on each angle iron are elongated holes.
[0011] In this invention, the material drop columns are installed on the receiving end of a static distributor. The number of drop columns is determined by the discharge port of the static distributor, and a certain distance is provided between adjacent drop columns. When raw material falls from the conveyor belt, it first falls onto the drop columns, and then from the drop columns into the discharge port. The drop columns absorb the impact of the material, mitigating the impact on the discharge port body and liner, thereby reducing the wear on the body and liner and effectively protecting them. The ceramic blocks have good wear resistance and a long service life.
[0012] The advantages of this utility model are: simple structure, low manufacturing cost, long service life, and reduced operation frequency of maintenance personnel. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and examples.
[0018] See attached document Figure 1-3 A static material feeder discharge column includes a channel steel 1, an angle iron 2, a connecting round steel 4, ceramic blocks 5, and mounting holes 7. The length of the channel steel 1 matches the discharge hopper 10 of the static material feeder. Both ends of the channel steel 1 are fixed to an angle iron 2. Each angle iron 2 has a mounting hole 7. Several ceramic blocks 5 are arranged inside the channel steel 1 along its length direction. The ceramic blocks 5 are connected together by the connecting round steel 4.
[0019] The rectangular ceramic blocks 5 inside the channel steel 1 along its length are respectively glued to the inside of the channel steel 1 with AB glue.
[0020] The channel steel 1 has several ceramic blocks 5 along its length, each with a central hole 6 that matches the connecting round steel 4.
[0021] A fixed round steel bar 3 is provided on each side of the channel steel 1, and the two ends of each fixed round steel bar 3 are fixed to the angle irons 2 at both ends of the channel steel 1.
[0022] The mounting holes 7 on each angle iron 2 are all elongated holes.
[0023] In this embodiment, refer to the appendix Figure 1 , 2 The material drop column is a rectangular structure consisting of a channel steel 1, two angle irons 2, two fixed round steels 3, a connecting round steel 4, and several ceramic blocks 5. Before manufacturing, the channel steel 1, angle irons 2, fixed round steels 3, and connecting round steels 4 are cut according to the installation dimensions. After cutting, ceramic AB glue is applied to the bottom, two sides, and back of the ceramic blocks 5 and pasted into the channel steel 1 until the channel steel 1 is full. Then, the connecting round steel 4 is passed through the central hole 6, and the mounting holes 7 of the two angle irons 2 are pre-processed. The two angle irons 2 are then fixedly welded to both ends of the channel steel 1, and the fixed round steel 3 is welded to both sides of the channel steel 1.
[0024] See attached document Figure 3 There are three material drop columns, which are fixed to the studs 8 of the receiving hopper 10 of the static distributor via mounting holes 7 and nuts 9. When raw material falls from the conveyor belt, it first falls onto the material drop columns, and then from the drop columns into the discharge ports, ensuring that the material falls evenly into the four discharge ports of the static distributor. The material drop columns bear the impact of the material, mitigating the impact on the discharge port body and liner, reducing the wear on the body and liner, and effectively protecting the discharge port body and liner. The ceramic block 5 has better wear resistance than cast steel alloy wear-resistant materials, thus extending the service life of the material drop columns.
