Description

Technical Field

[0001] This utility model belongs to the technical field of converter equipment and relates to a horizontal converter cold material crushing and screening device. Background Technology

[0002] Cold charge is one of the important reaction raw materials in horizontal nickel converters. It not only allows for the recovery of nickel from the cold charge but also helps control the reaction temperature within the furnace, thereby extending the converter's lifespan. Larger cold charge lumps (e.g., 50mm) that do not melt for extended periods after entering the converter can severely impact the converter's blowing process. Intermittent entry of cold charge into the system can disrupt the stable operation of the converter. Therefore, cold charge must be crushed before being added to the converter to prevent larger particles from entering. Currently, the existing method involves placing all the cold charge into the crusher for crushing, but particles smaller than 50mm do not require crushing. This results in an excessive amount of cold charge being added to the crusher at once, reducing crushing efficiency. Therefore, it is necessary to screen the cold charge before crushing to separate particles smaller than 50mm, eliminating the need for further crushing. Utility Model Content

[0004] Therefore, the present invention adopts the following technical solution: A horizontal converter cold material crushing and screening device includes a support frame. A chain plate conveyor is provided in the middle of the support frame along the length of the support frame. One end of the chain plate conveyor forms a discharge end and the other end forms a feed end. A conveyor belt is provided on the support frame along the length of the support frame. The conveyor belt is located below the chain plate conveyor. A hopper is provided on the support frame. The hopper is located near the feed end of the chain plate conveyor. A material passage is provided on the side wall of the hopper near the discharge end.

[0005] Furthermore, the chain plate screening conveyor includes a drive shaft located at one end of the support along its length, and a driven shaft located at the end of the support away from the drive shaft. The drive shaft is provided with a plurality of first sprockets, and the driven shaft is provided with a plurality of second sprockets corresponding one-to-one with the first sprockets. The second sprockets and the second sprockets are connected by a chain, and a plurality of conveying plates are provided along the length of the chain connection, with gaps formed between the conveying plates.

[0006] Furthermore, one end of the drive shaft is connected to a motor for driving the drive shaft to rotate.

Detailed Implementation

[0012] The present invention will now be described in detail with reference to the accompanying drawings: like Figure 1 and 2As shown, a horizontal converter cold material crushing and screening device includes a support 1. A chain plate screening conveyor 2 is provided along the length of the support 1 in the middle. One end of the chain plate screening conveyor 2 forms a discharge end 3, and the other end forms a feed end 4. Cold materials can be placed on the chain plate screening conveyor 2. The cold materials with smaller particle sizes can directly pass through the chain plate screening conveyor 2 and fall below it. The cold materials with larger particle sizes can be transported to the discharge end 3 and fall. Specifically, the chain plate screening conveyor 2 includes a drive shaft 201 set at one end of the support 1 along its length. The support 1 is away from the drive shaft 201. One end of the drive shaft 201 is provided with a driven shaft 202. The drive shaft 201 has multiple first sprockets 203. In this embodiment, two first sprockets 203 are provided, located at opposite ends of the drive shaft 201. The driven shaft 202 has multiple second sprockets 204 corresponding to the first sprockets 203. The first sprockets 203 and second sprockets 204 are connected by a chain 205. Multiple transmission plates 206 are provided along the length of the chain 205, with gaps 207 formed between them. The width of the gaps 207 is no greater than 50mm. 6 can rotate with chain 205 and is used to transport cold materials with larger particle sizes. Cold materials with smaller particle sizes can fall through the gap to the bottom of the chain plate screening conveyor 2. One end of the drive shaft 201 is connected to a motor 8 for driving the drive shaft 201 to rotate. The chain plate screening conveyor 2 is a modified version of an existing conventional chain plate conveyor. Compared with the existing conventional conveyor, its structure completes the screening of cold materials by setting gap 207. Its internal structure is the same as that of the existing conventional chain plate conveyor and is also equipped with a support device for supporting the upper conveyor plate 206. The support 1 is equipped with a hopper 5 with a vertical through structure. Located near the feed end 4 of the chain plate screening conveyor 2, the hopper 5 has a feed port 6 on its side wall near the discharge end 3. Cold material can be added to the chain plate screening conveyor 2 through the hopper 5. A horizontally arranged conveyor belt 7 is provided on the support 1 along the length of the support 1. The conveyor belt 7 is located on the lower side of the chain plate screening conveyor 2. Small cold material particles falling from the chain plate screening conveyor 2 can fall onto the conveyor belt 7 and be transported to the corresponding storage location for addition to the converter. In addition, the width of the conveyor belt 7 is greater than the length of the gap 207 to prevent particles falling from the gap from falling to the ground.

[0013] The method of using this utility model is as follows: When crushing cold materials, the crusher can be set below the discharge end 3 of the chain plate screening conveyor 2. First, the cold material is fed through the hopper 5 to the feed end 4 of the chain plate screening conveyor 2. The cold material moves towards the discharge end 3 through the feed port 6 on the conveyor plate 206 of the chain plate screening conveyor 2. During this process, cold materials with a particle size of less than 50mm fall down through the gap 207 between the conveyor plates 206 onto the conveyor belt 7 below the chain plate screening conveyor 2 (the conveyor belt 7 is in the opposite direction to the conveyor belt 2). The cold material is transported to the corresponding position for collection by the conveyor belt 7 and does not enter the crusher for crushing. Cold materials with a particle size greater than 50mm move with the conveyor plate 206 of the chain plate screening conveyor 2 to the discharge end 3 and fall into the crusher for crushing. This device can screen cold materials and effectively improve the crushing efficiency of the crusher.
