Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stacker-reclaimer cleaning, in particular to a high-pressure water sprinkling coal cleaning device for a stacker-reclaimer. Background Art
[0002] In the daily operation of a stacker-reclaimer, the belt is a crucial component responsible for transporting materials such as coal from one place to another. However, due to various reasons, such as belt speed, material humidity, material particle size, and the condition of the belt itself, coal may spill from the belt during transportation. These spilled coal powders gradually accumulate under the belt, forming so-called "coal accumulation". The existence of coal accumulation not only affects the operation efficiency of the stacker-reclaimer but also may lead to a series of safety hazards. Coal accumulation occupies the originally limited space, making the maintenance and repair of the equipment more difficult. Secondly, coal accumulation may trigger safety accidents such as fires. Especially in high-temperature or dry environments, coal powders are more likely to spontaneously combust. In addition, coal accumulation may cause additional wear to the belt, shortening its service life. To remove this coal accumulation, a large amount of manpower and material resources usually need to be invested. Cleaning personnel need to frequently enter the equipment area and use various tools such as brooms and shovels to manually remove the coal accumulation. This not only increases the work intensity but also may pose a threat to the health of the cleaning personnel because long-term exposure to coal dust may cause health problems such as respiratory diseases. In view of the above problems, how to efficiently and safely remove the generated coal accumulation has become a key issue that needs to be focused on and solved during the operation of the stacker-reclaimer. Therefore, a special study is conducted on the high-pressure water sprinkling coal cleaning device for the stacker-reclaimer to improve the cleaning efficiency and reduce the input of manpower and material resources.

[0016] The present utility model will be further described below in combination with the attached drawings and embodiments:
[0017] As Figures 1 to 3 shown, a high-pressure sprinkling coal cleaning device for a stacker-reclaimer includes: a sprinkling mechanism 1 and a landing gear 2. The sprinkling mechanism 1 includes a water tank 10, a valve 11, a booster pump 12, and a sprinkler pipeline 13. The water tank 10 is arranged above the tail car steel structure 3 of the stacker-reclaimer. The sprinkler pipeline 13 is led out from the water tank 10. The booster pump 12 is installed beside the water tank 10. The valve 11 is provided at the water outlet of the water tank 10. The water outlet of the valve 11 is connected to the water inlet of the booster pump 12. The sprinkler pipeline 13 is laid downward from the water outlet of the booster pump 12 to the lower part of the tail car steel structure 3 and then extends forward along the tail car steel structure 3 to the head of the tail car. A downward redirecting roller 4 is provided at the head of the tail car steel structure 3. The sprinkler pipeline 13 extends downward along the downward redirecting roller 4 to the lower part outside the cable tray and then is fixedly connected to the landing gear 2. The tail end of the sprinkler pipeline 13 is provided with a solenoid valve 14 and a high-pressure nozzle 15. The landing gear 2 is fixedly installed on the tail car leg steel structure 5.
[0018] The sprinkler pipeline 13 extends to the lower part of the belt through the landing gear 2. The booster pump 12 is turned on to transport the water in the water tank 10 to the lower part of the belt through the sprinkler pipeline 13 and eject it through the high-pressure nozzle 15. The water flow of the nozzle is controlled by adjusting the action size of the solenoid valve 14, achieving precise control. While ensuring the cleaning effect, it also reduces the waste of water resources.
[0019] The landing gear 2 includes: a fixed frame 20, an electric push rod 21, a first landing rod 22, a second landing rod 23, a movable arm 24, a first resistance rod 25, and a second resistance rod 26. The electric push rod 21 is hinged to the top of the fixed frame 20, the top of the first landing rod 22 is hinged to the right side of the fixed frame 20, the telescopic end of the electric push rod 21 is hinged to the side of the first landing rod 22 near the bottom, the bottom of the first landing rod 22 is hinged to the top of the second landing rod 23, the movable arm 24 is rotatably connected to the triangular support of the fixed frame 20, the top of the first resistance rod 25 is hinged to the top of the fixed frame 20, the bottom of the first resistance rod 25 is hinged to the top of the second resistance rod 26, the bottom of the second resistance rod 26 is hinged to the top of the movable arm 24, and the bottom of the second landing rod 23 is hinged to the side of the movable arm 24 near the bottom. When the electric push rod 21 contracts, it drives the movable arm 24 to rise, and when the electric push rod 21 extends, it drives the movable arm 24 to fall.
