Linkage interlock safety protection system for centrifuges and protective doors

Abstract

The invention relates to a linkage interlock safety protection system for centrifuges and protective doors. The linkage interlock safety protection system includes an acousto-optic alarm device, a mounting frame, a fixing bolt, a base, a guide line hole, a mounting plate, an adjusting screw, a limit plate, an adjusting handle, a door touch switch, a control box, a power distribution cabinet, an frequency converter and a centrifuge motor, the mounting frame is arranged on the upper side of a protective door, the base is vertically arranged at the top of the mounting frame, the acousto-optic alarm device is mounted on the base, the mounting plate is arranged on the upper side of the acousto-optic alarm device, the mounting plate is provided with an adjustment hole with internal threads on aninner wall, the adjusting screw is arranged in the adjusting hole, a door frame of protective door is provided with the door touch switch, the door contact switch is electrically connected with the acousto-optic alarm device through cables and the control box, the control box and the power distribution cabinet are electrically connected through cables, and the power distribution cabinet is electrically connected with the centrifuge motor through cables and the frequency converter. The linkage interlock safety protection system has the advantages that linkage interlock of the power distribution cabinet of a centrifuge and the protective door is realized through a circuit, and safety of personnel who mistakenly enters when the centrifuge works is ensured.

Description

technical field [0001] The invention relates to a protection system, in particular to a linkage interlock safety protection system for a centrifuge and a protection door. Background technique [0002] A centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. It can also be used to determine the electronic components, small equipment and other electrical and electronic products that are subjected to steady-state acceleration (constant acceleration) environment. Under the action of generated forces (except gravity), such as running vehicles, aerial vehicles, rotating machinery and projectiles, whether the adaptability and performance of the structure are good, and evaluate the structural integrity of some components. [0003] During its working process, the rotating arm with the test product rotates at high speed, and safety issues are extremely important, so reasonable and reliable safety prot...

Problems solved by technology

[0004] Although many precautionary measures have been taken in terms of safety protection, there are still potential safety hazards in the actual test process, for example: 1. Because the test operator forgot to close the protective door at the entrance of the protective wall and opened the test, other personnel mistakenly thought that the equipment was not in the test 2. The test operator closed the protective door of the protective wall entrance and opened the test according to the requirements, and other potential safety hazards caused by the entry of harmful personnel (customers) who are not familiar with the operation of the centrifuge
