technical field

The utility model relates to the technical field of superfine pulverizers, in particular to a hammer head of a superfine pulverizer.

Background technique

The crushing chamber of the vertical ultrafine pulverizer is equipped with a ring gear, a crushing disc and other components, and several hammerheads are installed on the circumference of the crushing disc close to the ring gear. The hammer head crushes the material at high speed, and the high-speed rotation of the hammer head throws the material to the ring gear, and the high-speed airflow impacts the material, causing strong collision and friction between the materials, so as to achieve the purpose of fine crushing. The traditional hammer head only performs high-speed crushing on the material through the striking surface. The high-speed airflow formed in the pulverizer is relatively gentle, and the material cannot be effectively crushed, so the crushing efficiency is low, and the crushing fineness cannot meet the requirements.

Utility model content

For solving the above technical problems, the technical solution of the utility model is:

A hammer head of a superfine pulverizer, comprising a hammer head blank, characterized in that one side of the hammer head blank is a striking surface, and at least two installation holes are arranged on the hammer head blank, and the hammer head blank The striking surface of the hammerhead body is located in the diameter direction of the crushing disk through the installation hole device, and the ring gear is on the outside of the crushing disk, and the side of the hammerhead body facing the ring gear is provided with a toothed structure. The hammer head of the ultrafine pulverizer described in the utility model processes a tooth-shaped structure on the side of the hammer body facing the ring gear, and when the hammer head rotates at high speed, the tooth-shaped structure on the hammer head is used to disturb the high-speed flow in the pulverizer. Airflow, increase the impact of high-speed airflow on materials, increase the impact and friction between materials, so as to achieve the purpose of improving the crushing effect and efficiency, shorten the crushing processing time, and make the crushing fineness meet the production requirements.

Further, the tooth-like structure is helical teeth inclined to the normal direction of the crushing disc, and the inclination direction of the tooth-like structure is opposite to that of the helical teeth on the ring gear, which can more effectively disturb the high-speed airflow and increase the interaction between materials. Impact and friction can effectively improve the crushing efficiency.

Further, the toothed structure is provided with two tooth grooves, and the inclination angles of the two tooth grooves are different, which reduces the wear of the material on the blank of the hammer head, thereby prolonging the service life of the hammer head.

Further, cemented carbide is installed on the striking surface and the toothed structure. The cemented carbide has good impact resistance and wear resistance, effectively protects the hammer body from being damaged, and can be conveniently used after the cemented carbide wears out. Replacement, improve the service life of the hammer body.

Further, the cemented carbide is connected to the striking surface and the toothed structure by oxygen welding, the connection method is simple, the structure strength is high, and it meets the requirement of high-strength operation of the pulverizer.

Further, the cemented carbide of the device on the striking surface has a wedge-shaped structure at the end away from the ring gear, and the thickness of the wedge-shaped structure gradually decreases toward the direction of the ring gear. At the same time, the material can be pushed to the gear ring, so that the material can be effectively crushed in the area between the hammer head and the gear ring, and the crushing effect can be improved.

Further, the connecting line of the center of the installation hole is perpendicular to the striking surface, which improves the installation stability of the hammer head and avoids the skewing of the hammer head during high-speed rotation, which causes the direction of the striking surface to deviate, which seriously affects the crushing effect and aggravates the impact of the hammer head. Hammer wear.

Further, the width of the side opposite to the striking surface on the hammerhead body is smaller than the striking surface, which reduces the consumables of the hammerhead, reduces the wind resistance received by the hammerhead during operation, reduces power consumption, improves the crushing effect, and improves the crushing effect. Machine output.

Compared with the prior art, the utility model has the advantages of:

The hammer head of the ultrafine pulverizer described in the utility model utilizes the toothed structure facing the ring gear to increase the impact of the high-speed airflow in the pulverizer on the materials, and increase the impact and friction of the materials, thereby effectively improving the pulverization efficiency and effect, and improving The output of the pulverizer, the amount of consumables for the production of the hammer head is small, and the hard alloy improves the wear resistance of the hammer head, thereby increasing the service life of the hammer head, reducing the production and maintenance cost of the hammer head, and is convenient for replacement and maintenance.
