Opening and closing control structure for main pipeline of hydrogen decrepitation furnace

Abstract

The invention discloses an opening and closing control structure for a main pipeline of a hydrogen decrepitation furnace. The structure comprises a heating cylinder, the heating cylinder is provided with a main pipeline connector communicated with an inner cavity of the heating cylinder, the main pipeline connector is used for being connected with a vacuum system of the hydrogen decrepitation furnace, the vacuum system comprises a rack and a main pipeline movably arranged on the rack, and a locking flange assembly is arranged at the end of the main pipeline. The main pipeline connector is provided with a connecting flange, and the connecting flange is matched with the locking flange assembly in an inserted mode. An insertion driving mechanism in transmission connection with the main pipeline is arranged on the rack, and the insertion driving mechanism is used for controlling the locking flange assembly to be connected with or separated from the connecting flange. The rack is further provided with a rotation driving mechanism used for driving the locking flange assembly to rotate. The main pipeline connector is further provided with an opening and closing valve. Independent control over a gas connector is achieved, the structure is simple and reasonable, operation is convenient, the automation degree is higher, external air can be effectively prevented from entering the cylinder during discharging, and the product quality can be improved.

Description

technical field [0001] The invention relates to the technical field of NdFeB processing equipment, in particular to an opening and closing control structure of a main pipeline of a hydrogen crushing furnace. Background technique [0002] Hydrogen crushing furnace, also known as hydrogen crushing furnace, is a processing equipment for NdFeB alloy materials. Its principle is to use the characteristics of grain boundary fracture and transgrain boundary fracture produced by the rare earth permanent magnet alloy in the process of hydrogen absorption and dehydrogenation. Cause alloy pulverization, so as to obtain alloy powder with a certain particle size. After the NdFeB ingot is processed by the hydrogen crushing furnace, it directly enters the next process-jet mill crushing, which can effectively reduce the oxidation probability of the material. [0003] The heating cylinder is one of the core components of the hydrogen crushing furnace, and the hydrogen crushing process of the...

Problems solved by technology

This manual operation method is very inconvenient, and it takes a certain amount of time to cover the end cap. During this process, some air will still enter the cylinder, resulting in an increase in the oxygen content in the cylinder and affecting product quality.
