Technical Field
[0001] This utility model relates to the field of chemical waste liquid collection and treatment technology, and in particular to a multifunctional chemical laboratory waste liquid collection and treatment device. Background Technology
[0002] A multi-functional chemical laboratory bench is a workbench device specifically designed for chemical experiments. These experiments generate various waste liquids containing toxic, harmful, corrosive, flammable, and explosive substances. Direct discharge into the environment can cause serious pollution to soil, water, and air. For example, waste liquids containing heavy metal ions can lead to heavy metal pollution in the soil, affecting crop growth and ecological balance; waste liquids containing organic solvents can pollute the air after volatilization, posing a threat to human health. Waste liquid collection and treatment devices can effectively collect and treat these waste liquids.
[0003] Waste liquid collection and treatment device is a special equipment used to collect and treat waste liquid generated by chemical laboratory benches. It purifies the collected waste liquid and then treats it to meet the discharge standards before discharging it.
[0004] Traditional methods for treating waste liquid in chemical laboratories often have several problems. On the one hand, the lack of effective filtration and preliminary treatment methods makes it easy for impurities in the waste liquid to clog pipes, affecting the efficiency of waste liquid collection and subsequent treatment. On the other hand, during the waste liquid treatment process, the mixing effect between the reagent and the waste liquid is poor, and the residue after treatment is difficult to clean, requiring frequent disassembly of the filter device for cleaning, which increases the complexity and cost of operation. To address these issues, a multifunctional waste liquid collection and treatment device for chemical laboratories is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a multifunctional chemical laboratory waste liquid collection and treatment device, which aims to improve the problems of lack of effective filtration and preliminary treatment methods and poor fusion effect of reagents and waste liquid during treatment in the existing technology.

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, waste liquid is poured in through the inlet pipe and flows into the funnel, impacting the blades of the impeller. This causes the impeller to rotate and strike the spring plate, which in turn causes the filter disc to vibrate up and down. This vibration of the filter disc effectively performs preliminary filtration of the waste liquid, increases the flow rate of the waste liquid, and prevents the waste liquid from overflowing.

This pushes the filtered residue to the drain outlet for discharge, thereby accelerating the fusion treatment of the reagent and waste liquid. At the same time, the U-shaped filter screen can be cleaned without disassembling it for cleaning. Attached Figure Description

When the waste liquid impacts the impeller 10, the spring plate 8 is struck, causing the filter disc 6 to vibrate up and down.
[0035] refer to Figure 2 , Figure 3A coupling 9 is rotatably connected to the top of the inlet pipe 3, providing support and a rotating shaft for the impeller 10. The impeller 10 is rotatably connected to the outside of the coupling 9, and its outer surface contacts the bottom of the spring plate 8. When the waste liquid flows into the funnel 4, the impeller 10 is impacted and rotates, striking the spring plate 8 and causing the filter disc 6 to vibrate.

[0036] refer to Figure 4 , Figure 5 A cleaning component for removing filtered material is fixedly connected to the top of the stirring frame 14. The cleaning component includes a sealing box 15, which is located at the bottom of the stirring frame 14 and has a box-shaped structure that wraps around the outside of the stirring frame 14. A driving bevel gear 16 is fixedly connected to the top of the stirring frame 14. The driving bevel gear 16 meshes with a driven bevel gear 18, transmitting power from the motor 13 to drive the auger roller 17 to rotate.
[0037] A screw conveyor roller 17 is rotatably connected to the center of the sealed box 15. The screw conveyor roller 17 is cylindrical in shape, with a driven bevel gear 18 fixed in the center of its exterior and inclined blades on its exterior. The driven bevel gear 18 is fixedly connected to the center of the exterior of the screw conveyor roller 17, and the driven bevel gear 18 meshes with the driving bevel gear 16, receiving power from the motor 13 to drive the screw conveyor roller 17 to rotate. The external teeth of the driving bevel gear 16 are meshed with the external teeth of the driven bevel gear 18.
[0038] A drain outlet 19 is fixedly connected to the bottom end of the storage tank 1 on the side away from the collection chamber 11. The drain outlet 19 is fixed to the bottom end of the storage tank 1 on the side away from the collection chamber 11 and is flush with the U-shaped filter screen 20. It is used to discharge the treated residue.
[0039] A U-shaped filter screen 20 is fixedly connected to the middle of the processing chamber 12. The U-shaped filter screen 20 is fixed in the middle of the processing chamber 12 to filter and purify the waste liquid. The external rotatable connection of the screw roller 17 is connected to the top of the U-shaped filter screen 20. A discharge port 21 is fixedly connected to the bottom end of the storage tank 1 on the side away from the collection chamber 11. The discharge port 21 is fixed at the bottom end of the storage tank 1 on the side away from the collection chamber 11, and the treated waste liquid is discharged from here.
[0040] A water pump 22 is fixedly connected to the top center of the storage tank 1, at the location of the treatment chamber 12. A connecting pipe 23 is fixedly connected to the input end of the water pump 22, connecting the collection chamber 11 and the treatment chamber 12. A pH measuring instrument 24 is installed at the top center of the connecting pipe 23 to measure the pH value of the waste liquid, allowing researchers to accurately add the appropriate amount of reagent. The connecting pipe 23 is fixedly connected to the top center of the storage tank 1. A feeding port 25 is fixedly connected to the top end of the storage tank 1, away from the inlet pipe 3, for adding the reagent used to treat the waste liquid. A display bar 26 is installed on the front side of the storage tank 1, away from the treatment chamber 12, to display the amount of waste liquid collected.
[0041] Working principle: When in use, place the device in the bottom cabinet of the experimental platform, then pass the liquid inlet pipe 3 and the funnel 4 through the mounting hole on the table of the multi-functional experimental platform, and then connect and fix the liquid inlet pipe 3 to the float pump 2.
[0042] After the device is fixed in place, the experimenter can open the sealing cap at the top of the funnel 4 and pour the experimental waste liquid into the funnel 4 through the inlet pipe. The waste liquid flows into the inlet pipe 3 along the funnel 4, impacting the blades of the impeller 10. The impeller 10 rotates, striking the spring plate 8 and causing the filter plate 6 to vibrate up and down. This filters the waste liquid and causes the filtered residue to float, thereby accelerating the flow rate of the waste liquid and preventing it from overflowing. When all the waste liquid has been poured into the collection chamber 11 of the storage tank 1 and is full, the waste liquid in the collection chamber 11 will cause the float of the float pump 2 to rise and fall, thereby triggering the float pump 2 to close the waste liquid inlet and triggering the alarm 5, which will inform the experimenter that the waste liquid has been collected.
[0043] Upon receiving the signal, the experimenters can start the water pump 22 to collect the waste liquid in the collection chamber 11 through the connecting pipe 23 and transfer it to the treatment chamber 12. During the transfer of waste liquid in the water pump 22, the pH value detection instrument 24 will detect the pH value in the waste liquid, allowing the user to accurately pour the dosage of the reagent through the feeding port 25. Furthermore, when the waste liquid enters the storage tank 1, the motor 1 and the liquid inlet pipe 3 will start in time, driving the stirring rack 14 to stir and accelerate the fusion, allowing the U-shaped filter screen 20 to filter and purify the liquid, and finally discharge it from the discharge port 21.
[0044] After all the treated waste liquid has been discharged, the experimenter can open the drain outlet 19 and start the motor 13. The motor 13 will mesh with the driven bevel gear 18 fixed to the auger roller 17 through the driving bevel gear 16 at the bottom, driving the driven bevel gear 18 to rotate. The driven bevel gear 18 will drive the auger roller 17 to rotate. After the auger roller 17 rotates, the externally inclined blades will push the residue from the U-shaped filter screen 20 process to gradually move towards the drain outlet 19, and finally discharge it from the drain outlet 19.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
