Problems solved by technology

[0004] The above-mentioned existing equipment requires people to continuously turn the handle by hand, and then drive the piston to move up and down continuously to control the flow of liquid in the liquid storage tank, but this control method cannot be automatically adjusted according to the degree of reaction in the reaction tank. Adjust the rotation of the piston and the flow of the liquid in the liquid storage tank. The acid-base neutralization reaction between the waste liquid and the neutralization reagent will generate a lot of heat, so that the chemical substances in the waste liquid will not react at low temperature and will be released at high temperature. Reactions occur, and the safe disposal of waste liquid cannot be guaranteed

Embodiment 1

[0037] see Figure 1-Figure 4 , a kind of waste liquid treatment equipment used in the laboratory, comprising a housing 1, a liquid injection cylinder 2 is fixedly installed on the inner top wall of the housing 1, and a liquid injection tank 3 is opened in the upper half of the liquid injection cylinder 2, and the injection The lower half of the inside of the liquid cylinder 2 is provided with a limited flow groove 4;

[0038]The inner bottom wall of the housing 1 is rotatably provided with an inner cylinder 9, and a flow-limiting plug 5 coupled with the shape of the inner wall of the flow-limiting groove 4 is movably arranged above the inner cylinder 9. The plug 5 is a conical body coupled with the shape of the inner wall of the flow-limiting groove 4. The flow-limiting plug 5 of the conical truncated body can completely block the flow-limiting groove 4. The control device arranged inside the inner cylinder 9 drives the flow-limiting plug 5 to Move up and down in the flow li...

Embodiment 2

[0044] see Figure 1-Figure 3 , on the basis of Embodiment 1, the outer wall of the current limiting plug 5 is provided with a copper coil 6, the inner wall of the current limiting tank 4 is provided with a voltage plate 7 matching the copper coil 6, and the two sides of the housing 1 are also provided with heat dissipation 8, the output end of the voltage sheet 7 is electrically connected to the input end of the radiator 8. When the current limiting plug 5 moves upward and completely extends into the current limiting groove 4, it proves that the temperature in the housing 1 is relatively high at this time, and the current limiting plug 5. The copper coil 6 on the current-limiting plug 5 fully inserted into the current-limiting groove 4 is in contact with the voltage plate 7 on the inner wall of the current-limiting groove 4, and conducts the circuit of the radiator 8, which can make the radiator 8 work and dissipate heat, effectively The excess heat in the casing 1 is dissipa...

Embodiment 3

[0046] see Figure 2-Figure 5 , on the basis of Embodiment 1 and Embodiment 2, the outer walls of the two connecting rods 13 are also provided with teeth 14, the outer walls of the teeth 14 are meshed with a driving wheel 15, and the center of the driving wheel 15 is fixedly installed with a transverse shaft 16 , the two ends of the transverse shaft 16 extend to the outside of the inner tube 9 and are fixedly connected with driving wheels 17, the outer walls of the two driving wheels 17 are movably provided with transmission chains 18, and the inner walls of the two transmission chains 18 are movably provided with The driving wheel 19 and the centers of the two driven wheels 19 are fixedly equipped with stirring shafts 20, and the two stirring shafts 20 are respectively rotated and arranged on the left and right sides of the inner cylinder 9, and the outer walls of the two stirring shafts 20 are fixedly equipped with stirring blades 21 , the ends of the two stirring shafts 20 ...

Abstract

The invention relates to the technical field of laboratory waste liquid treatment, and discloses laboratory waste liquid treatment equipment which comprises a shell, a liquid injection cylinder is fixedly mounted on the inner top wall of the shell, a liquid injection groove is formed in the upper half portion of the interior of the liquid injection cylinder, and a flow limiting groove is formed in the lower half portion of the interior of the liquid injection cylinder; and a flow limiting plug moves up and down in the flow limiting groove to adjust the size of a liquid injection channel of the flow limiting groove. The waste liquid and a waste liquid treatment reagent are subjected to a neutralization reaction in the shell to release heat, so that the temperature of the mixed liquid is increased, the heat is transferred into mercury through the heat conducting rod, the mercury is heated and rapidly evaporated, the air pressure above the mercury is increased, and the air pressure above the mercury is increased to push a sealing sliding plug to move upwards; and the sealing sliding plug moves upwards to drive the flow limiting plug to move upwards through the connecting rod, the flow limiting plug moves upwards to stretch into the flow limiting groove, the size of a liquid injection channel of the flow limiting groove is adjusted, and then the inflow amount of the waste liquid treatment reagent is reduced.

Description

technical field [0001] The invention relates to the technical field of laboratory waste liquid treatment, in particular to waste liquid treatment equipment for laboratories. Background technique [0002] At present, various chemical experiments are frequently done in schools, research institutes and other units, and chemical experiments will produce a large amount of waste liquids. Most of the liquids generated after chemical reactions have seriously exceeded the standard of acid and alkali, and direct discharge will cause great harm to the environment. , and there is no special treatment equipment for chemical waste liquid treatment. Different waste liquids are often poured into a container, which may cause chemical reactions and affect the health of students. At the same time, the acid-base neutralization reaction will generate a lot of heat. If If the heat is not discharged in time, it is easy to cause the chemical substances in the waste liquid to react in a high tempera...
