AI Technical Summary

Technical Problem

When pulverizing lightweight materials under negative pressure, the materials tend to float, resulting in insufficient pulverization, low efficiency, low equipment output, and high energy consumption, making it difficult to meet the precision and efficiency requirements of industrial production.

Method used

A high-efficiency worm gear crusher was designed. By setting a cavity and a guide wheel on the outer circumference of the crushing wheel, the air pressure pulsation generated by the high-speed rotation causes light materials to float and sink. Multiple crushing is achieved by the high-speed impact of the crushing hammer. Combined with the guide plate and the ring mounting plate to form a honeycomb structure, the material is ensured to have sufficient impact time and pressure differential oscillation in the crushing zone, thereby improving the crushing efficiency.

Benefits of technology

It achieves efficient crushing of lightweight materials, improves crushing efficiency and finished product output, reduces energy consumption, and meets the needs of industrial production for precision and efficiency.

Abstract

This invention discloses a high-efficiency worm gear crusher, including a frame, a housing mounted on the frame, a crushing chamber inside the housing, a crushing wheel rotatably mounted inside the crushing chamber, and a guide wheel rotatably mounted inside the crushing chamber. The guide wheel includes a wheel body, a guide hole communicating with a connecting hole on the wheel body, and a discharge hole communicating with the guide hole on the outer circumferential surface of the wheel body. Multiple crushing hammers are fixedly mounted on the outer circumferential surface of the crushing wheel, and multiple cavities are provided on the outer circumferential surface of the crushing wheel. The housing also has a feed inlet communicating with a feed chamber and a discharge outlet communicating with a discharge chamber. Due to the cavities on the outer circumferential surface of the crushing wheel, when the crushing wheel rotates at high speed, it generates pulsating oscillations in the air pressure inside the crushing chamber, causing the material that is sucked up by the negative pressure to rise and fall. Under the high-speed impact of the crushing hammers, the material hits the inner wall of the crushing chamber. The fine particles formed by the impact are sucked away by the negative pressure in the system, while the coarse particles are bounced back into the cavity under the action of force after being hit by the inner wall of the crushing chamber, and are crushed again by the crushing hammers.
