Problems solved by technology

[0003] The purpose of the present invention is to propose a primary safety valve for gyratory crushers, which can effectively solve the problem that the overload causes the hydraulic system to exceed the safety set pressure, the safety valve is opened to spray oil, and the oil is directly sprayed around the crusher and on the equipment.

Embodiment Construction

[0008] Below in conjunction with accompanying drawing, the present invention will be further described: figure 1 As shown, since the primary safety valve is the self-protection device of the crusher, the modification must be carried out without changing the function of the safety valve. By installing a pipeline at the outlet of the primary safety valve 2 and connecting a drain oil tank 3, overload occurs , the oil that suddenly spills out of the pipeline enters the oil drain tank 3, and the operator can grasp the change of the oil volume in the oil drain tank 2 through the observation window 4, and judge whether the safety valve is opened to inject oil, and at the same time, the oil drain in the oil tank 2 The collected oil can be recycled and reused.

[0009] The last and most important thing is that the specific implementation is a further description of the present invention rather than a limitation. For those of ordinary skill in the art, further transformations can be ma...

Abstract

The invention discloses a primary safety valve of a gyratory crusher. A pipeline is arranged at an outlet of the primary safety valve (2) and is externally connected with a leakage oil tank (3); an observation window (4) is formed in the wall of the oil tank; by the external leakage oil tank, the problem that oil is sprayed when the conventional safety valve is switched on is effectively solved; the change of oil amount in the oil tank can be mastered through the observation window so as to judge whether the safety valve is switched on for spraying oil when being switched on; meanwhile, the oil collected in the oil tank can be recycled and reused.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a primary safety valve for a gyratory crusher. Background technique [0002] The hydraulic system of the MK-II54-75 gyratory crusher is equipped with a balance cylinder. When there is a large amount of ore in the crushing cavity, sometimes it will push the main shaft to move upward quickly, as if "jumping". The balance cylinder ensures that the piston rises together with the main shaft when the main shaft jumps up, so that the main shaft can easily return to the initial position. The system has two 750PSI primary safety valves installed in the MPS oil supply pipeline connected with the balance cylinder. When the pressure in the hydraulic system is too high, two safety valves can quickly vent to release the pressure. In the case of severe iron overload, the safety valve can quickly lower the main shaft. In actual use, when the crusher liner is used in the later stage, there are ...
