Abstract
This utility model relates to a laboratory automatic power-off device for water failure, which can automatically cut off power supply of a condensation backflow device or a sorbitic extraction device, etc. Solvent will not be volatilized to the air, thereby reducing waste and environment pollution, preventing fires, and improving work efficiency. This device has advantages of convenient installation and use, and high reliability. This utility model comprises a casing, which is provided with a lever on the bottom. One end of the lever is provided with a water tank and the other end is disposed with an object, with which a plug is connected and of which the weight is bigger than self weight of the tank and smaller than the weight of the tank filled with water. A Dia 5mm hole is disposed at the bottom of the water storage tank.
Description
One, technical field:
The utility model relates to a kind of laboratory and controls breaker device automatically with cutting off the water, and it can be used on the similar devices such as laboratory condensing reflux or Soxhlet extraction.
Two, background technology:
At present, during work such as extracting in the laboratory, concentrate, organic compound is synthetic, generally need to use similar devices such as condensing reflux or Soxhlet extraction.Because a variety of causes, the laboratory usually can cut off the water suddenly, and causing does not have condensed water in the condensing unit, but heater makes solvent evaporates cause waste and environmental pollution or cause fire in atmosphere also continuing heating simultaneously.
Three, utility model content:
The utility model is in order to solve the weak point in the above-mentioned background technology, provide a kind of laboratory to control breaker device automatically with cutting off the water, it can make devices such as condensing reflux or Soxhlet extraction cut off the power supply automatically under the situation of cutting off the water supply, solvent can not evaporate in the atmosphere, thereby cut the waste, increase work efficiency, and easy to install, the reliability height.
For achieving the above object, the technical solution adopted in the utility model is:
Breaker device is controlled automatically with cutting off the water in a kind of laboratory, its special character is: comprise casing, bottom half is provided with a lever, one end of lever is provided with aqua storage tank, the other end of lever is provided with weight, be connected with plug on the weight, weight of heavy is greater than the deadweight of aqua storage tank, the weight during less than the aqua storage tank filled with water.
Above-mentioned aqua storage tank bottom has aperture.
The hole diameter of above-mentioned aqua storage tank bottom is 5 millimeters.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1, the utility model can make the outage automatically of device such as condensing reflux or Soxhlet extraction under the situation of cutting off the water supply, and solvent can not evaporate in the atmosphere, thereby cuts the waste and environmental pollution and prevent that fire from taking place, and increases work efficiency.This device is easy to install, the reliability height.
2, the utility model is specially adapted to that the laboratory works long hours and night is unattended, can obviously increase work efficiency, and be a kind of little, effective, simple and practical laboratory installation of investing.
Four, description of drawings:
Fig. 1 is cut off the water structural representation under the state of the utility model;
Fig. 2 has structural representation under the water state for the utility model.
Five, embodiment:
Referring to Fig. 1, Fig. 2, the utility model utilizes lever principle, be provided with a lever 6 in casing 7 bottoms, one end of lever 6 fulcrums is installed aqua storage tank 1, it is 5 millimeters aperture 2 that the bottom of aqua storage tank 1 has a diameter, can make the speed of the speed of water into like this, so fill water in the aqua storage tank 1 all the time greater than water outlet.The other end of lever 6 fulcrums is installed a weight 3, is connected with the plug 4 of experimental provision on the weight 3, and the weight of weight 3 is greater than the weight of the aqua storage tank 1 of sky, the weight during less than aqua storage tank 1 filled with water.
During real work, aqua storage tank 1 is placed under condenser pipe 8 delivery ports, when condensation flow stops, water in the aqua storage tank 1 can flow out from bottom aperture 2, the lever 6 one end gravity that aqua storage tank 1 is set are reduced, lever 6 other ends that weight 3 is set are forcing the plug 4 that is installed on the weight 3 to separate with socket 5 under the effect of gravity, realize automatic circuit break function.When resuming water supply, the aqua storage tank end of lever 6 descends, and attaching plug 4 inserts socket 5 automatically, restores electricity.A whole set of experimental provision carries out work automatically, realizes long-time unattended process.
