Hydraulic start and stop system of double rotor hammer crusher

Abstract

The invention relates to a hydraulic start and stop system of a double rotor hammer crusher. The system is characterized by being provided with a base, wherein a lower box body is arranged on the base; a blanking box is fixedly arranged on the upper part of the middle position of the lower box body; rotors are symmetrically arranged on the lower box body from middle to outside, separately, by taking the blanking box as axis of symmetry; an overhaul door covers the rotors; the overhaul door is hinged to the lower box body; the hydraulic start and stop system is arranged between the overhaul door and the lower box body; motors are separately arranged on two sides of the base to drive the rotors to work; safety pin holes are separately formed in the overhaul door and the lower box body; whenthe overhaul door is fully opened, the opening position of the overhaul door is fixed through a safety pin roll, and the hydraulic start and stop system can open or close the overhaul door needed to be opened conveniently and rapidly, and meanwhile, the safety pin hole fixes the overhaul door effectively when the overhaul door is fully opened to prevent safety accidents.

Description

technical field [0001] The invention relates to mechanical brick making, in particular to a hydraulic opening and closing system of a double-rotor hammer crusher. Background technique [0002] The technical level of brick and tile equipment and sintering process has been developed rapidly in recent years, and is basically in line with the international level. In the production process of brick and tile enterprises, the crushing of raw materials is the first link. At present, most of them at home and abroad use hammer crushers. The rotor hammer crusher has been widely used in recent years. During the working process, the double-rotor turntables are equipped with wear-resistant hammer heads, which rotate relatively at high speed, and impact and crush large-grained materials under a huge moment of inertia. Material leaks from the gap of the sieve plate, which causes the wearing parts of this kind of equipment to be consumed quickly and needs to be replaced frequently. However, ...

In the production process of brick and tile enterprises, the crushing of raw materials is the first link. At present, most of them at home and abroad use hammer crushers. The rotor hammer crusher has been widely used in recent years. During the working process, the double-rotor turntables are equipped with wear-resistant hammer heads, which rotate relatively at high speed, and impact and crush large-grained materials under a huge moment of inertia. The material leaks from the gap of the sieve plate, which causes the wearing parts of this kind of equipment to be consumed quickly and needs to be replaced frequently. However, the inspection door of the crusher is generally very heavy, which brings great difficulties to the maintenance work.
