Description

Technical Field

[0001] The present application relates to the field of crystallized salt cleaning equipment, and in particular to a vibration impact device. Background Art

[0002] In most blast furnace ironmaking operations, sintered ore accounts for over 75% of the production. Sintered ore is typically produced in a sintering furnace. Over time, solidified salt crystallizes between the sintering grate bars, causing them to clog. According to surveys, grate clogs in sintering furnaces are a common and difficult-to-solve problem in sintering furnaces. This problem negatively impacts sintering efficiency, quality, output, equipment life, and increases production costs.

[0003] Currently, the main method for cleaning clogged sintering grate bars is chemical cleaning, which uses the reaction between chemical substances and solidified crystallized salts on the grate bars to dissolve them and drop them off. However, the reaction time is long and the cleaning efficiency is low. Utility Model Content

[0004] In order to facilitate the rapid cleaning of solidified crystallized salt between sintering grate bars, the present application provides a vibration impact device.

[0005] The present application provides a vibration impact device, which adopts the following technical solution:

[0006] A vibration impact device comprises a mounting seat, an impact tool and an excitation generator. The excitation generator and the impact tool are both mounted on the mounting seat. The excitation generator is used to act on the impact tool to make the impact tool vibrate.

[0007] By adopting the above technical solution, when in use, the mounting base can be installed on the robotic arm, and then the robotic arm is used to move the device to a suitable position, and then the excitation generator is turned on, so that the impact tool can generate a small amplitude high-frequency vibration and heat. After the end of the impact tool contacts the crystal, the vibration causes the material medium particles to produce mechanical and thermal effects, which can open the internal molecular structure of the material, making the separation of the material easier, and has a good separation effect on the crystallized salt; using this device to clean the solidified crystallized salt between the sintering grate bars is simple and fast, and the cleaning effect is good.

[0008] Optionally, an air outlet is provided on the impact tool, and under the action of an external air pump, the impact tool sprays high-pressure gas through the air outlet.

[0009] By adopting the above technical solution, after the solidified crystallized salt between the sintering grate bars is shattered, the impact tool is made to spray high-pressure gas through an external air pump, so that the shattered solidified crystallized salt can be blown away, effectively removing the solidified crystallized salt in the tiny gaps.

[0010] Optionally, a variable amplitude rod is installed between the vibration generator and the impact tool, and the variable amplitude rod is used to adjust the vibration amplitude of the impact tool.

[0011] By adopting the above technical solution, the vibration amplitude of the impact tool can be increased.

[0012] Optionally, an adjusting rod is installed on the mounting seat, and the adjusting rod includes a fixed rod and an extension rod. The fixed rod is used to be fixed on the mounting seat, one end of the extension rod is inserted into the fixed rod, and the other end of the extension rod is used to connect the impact tool. The fixed rod is provided with a positioning piece for locating the position of the extension rod.

[0013] By adopting the above technical solution, the distance between the impact tool and the mounting seat can be adjusted, thereby improving the use range of the impact tool.

[0014] Optionally, the positioning member includes a pin, which is threadedly connected to the fixing rod, and one end of the pin extends through the fixing rod into the fixing rod, and a plurality of through holes for inserting the pin are opened on the outer wall of the extension rod along its own length direction.

[0015] By adopting the above technical solution, when adjusting the position of the impact tool, the extension rod is first moved to a suitable position, and then the latch is inserted into a suitable through-hole; the positioning member has a simple structure and is easy to operate.

[0016] Optionally, a fixing sleeve is fixedly connected to the impact tool, and one end of the extension rod away from the fixing rod is used to be inserted into the fixing sleeve. The extension rod is provided with a limiting component for limiting the extension rod from being separated from the fixing sleeve.

[0017] By adopting the above technical solution, it is easy to replace the impact tool.

[0018] Optionally, the limiting assembly includes a spring and a block, a limiting groove is provided on the outer wall of the fixing rod, the spring is fixedly connected to the limiting groove, the block is fixedly connected to the spring, and the block can move in the limiting groove, and an opening for the block to be inserted into is provided on the inner wall of the fixing sleeve. When the spring is not deformed, the block is partially located in the limiting groove, and the block can be partially inserted into the opening.

[0019] By adopting the above technical solution, when replacing the impact tool, press the card block to disengage the card block from the opening, and then disengage the extension rod from the fixed sleeve; when installing the impact tool, press the card block to make the card block completely enter the makeshift groove, and then insert the extension rod into the fixed sleeve. When the card block moves to the opening position, the card block partially extends out of the limit groove under the action of the spring and is stuck in the opening, thereby keeping the impact tool stable.

[0020] Optionally, a surface of the clamping block away from the fixing rod is an arc-shaped convex surface.

[0021] By adopting the above technical solution, the arc-shaped convex surface of the clamping block is set, and when installing the impact tool, there is no need to press the clamping block, which reduces the operation steps.

[0022] In summary, this application has the following beneficial technical effects:

[0023] 1. This application uses an impact cutter in conjunction with a vibration generator to quickly clean the solidified crystallized salt between the sintering grate bars;

[0024] 2. This application utilizes an external air pump to allow the impact tool to spray high-pressure gas, thereby blowing away the shattered solidified crystallized salt and effectively removing the solidified crystallized salt in the tiny gaps. BRIEF DESCRIPTION OF THE DRAWINGS
