Abstract
The invention provides a centrifuger safety protection device for a laboratory. After a swiveling head cover is screwed, a person is required to touch between a swiveling head and the swiveling head cover to see whether a seam exists, and if a seam exists, the swiveling head and the swiveling head cover need to be unscrewed and then are screwed again until no seam is ensured, and then a centrifuger can be started. But at present, certain operators still do not implement the safety operation regulations, resulting in invocatable safety accidents. The centrifuger safety protection device for the laboratory comprises an infrared detection device (3) mounted between the swiveling head cover (1) and the swiveling head (2) of the centrifuger, the infrared detection device is connected with an integrated chip (4), and the integrated chip is connected with an alarm (5). The invention serves as a centrifuger safety protection device used in a laboratory.
Description
Technical field
The present invention relates to a kind of chemical engineering experiment apparatus, be specifically related to a kind of laboratory centrifuge safety device.
Background technology
Centrifuge is to utilize centrifugal force, the machinery of each component in the mixture of separating liquid and solid particle or liquid and liquid.Centrifuge is mainly used in the solid particle in the suspension and liquid are separated; Or with two kinds of density differences in the emulsion, immiscible liquid separates (for example isolating cream from milk) again; It also can be used for getting rid of the liquid in the wet solid, for example dries wet clothes with washing machine; Special hypervelocity channel separator is the admixture of gas of separable different densities also; Utilize the different characteristics of solid particle sinking speed in liquid of different densities or granularity, some sedimentation centrifuges also can carry out classification by density or granularity to solid particle.Centrifuge is widely used in the departments such as chemical industry, oil, food, pharmacy, ore dressing, coal, water treatment and boats and ships.
At present, what the laboratory was commonly used is electric centrifuge, the electric centrifuge velocity of rotation is fast, if use procedure is not noted having very large potential safety hazard, usually, for clear in the safe handling of the centrifuge regulation centrifuge when pre-cold state, centrifuge cup must be closed, take out rotary head after the centrifugal end and will be inverted on the experimental bench, dry remaining water in the chamber, centrifuge cup is in open mode.Rotary head rotary head lid when precooling can be placed on the platform of centrifuge, or is placed on the experimental bench, and ten million must tighten floating being placed in the rotary head, in case because error starting, the rotary head lid will fly out, and causes the accident.Rotary head is covered must be seamless with having between finger touch rotary head and the hub cap after tightening, and will turn on again if any the slit and tighten, until confirm seamlessly can start centrifuge.But certain operations person is still arranged not according to the safety operation regulation enforcement, cause irremediable security incident.
Summary of the invention
The objective of the invention is provides a kind of laboratory centrifuge safety device for the problem of above-mentioned existence, can avoid preferably the situation that centrifugal lid is not fastened or the rotary head lid is not fastened, and avoids the generation of security incident.
Above-mentioned purpose is achieved through the following technical solutions:
The laboratory centrifuge safety device comprises the infrared detecting device that is installed between centrifugal basket skull and the rotary head, and described infrared detecting device connects integrated chip, and described integrated chip connects alarm.
Described laboratory centrifuge safety device, described integrated chip comprises signal acquisition circuit, described signal acquisition circuit connects amplifying circuit, described amplifying circuit connects filter circuit, described filter circuit connects logic judging circuit, and described logic judging circuit connects alarm.
Beneficial effect:
1. the present invention adopts infrared detecting device to detect at any time the state that covers tightly of electric centrifuge rotary head lid, does not cover tightly if infrared detecting device detects the electric centrifuge rotary head, then can send warning, and the reminding user safety operation is avoided causing danger.
2. the present invention adopts infrared detecting device, and working stability is reliable.
