Description

Technical Field

[0001] The present invention relates to the technical field of chemical recycling and treatment, and in particular to a highly efficient treatment device for chemical waste. Background Art

[0002] In modern chemical laboratories, the use of acid and alkali solutions and organic solvents is extremely common. These chemicals are essential for experimental research and industrial applications, but they are also potential environmental pollutants. Due to their corrosiveness, toxicity or flammability, many acid and alkali solutions or organic solutions cannot be discarded into public sewers or the environment at will, as this may cause serious environmental pollution and ecological damage, and violate relevant environmental regulations.

[0003] At present, in order to protect the environment and comply with laws and regulations, laboratories usually need to carry out professional harmless treatment of these chemical wastes. This process may include neutralization reactions to reduce pH, oxidation-reduction reactions to decompose harmful components, and physical separation methods such as distillation or filtration, aiming to convert harmful substances into safer forms. In addition, recycling and reuse is also an important strategy. Through specific technical means, valuable chemicals can be extracted to reduce resource waste.

[0004] However, in actual operation, there is a significant problem: most of this waste is actually water-based solution, which contains low concentrations of target chemicals. Direct recycling and treatment will result in the storage of a large amount of chemical solution waste, which not only takes up a lot of space, but also increases storage costs and management difficulties, which is not conducive to long-term and effective recycling. In this case, the volume of waste becomes an urgent problem to be solved because it directly affects the cost-effectiveness of transportation, treatment and final disposal. Summary of the invention

The lower end of the heat exchange cover 7 is connected to a circle of annular liquid outlet pipe 74, and the upper end of each circulation inner tube 82 is connected to the annular liquid outlet pipe 74. The annular liquid outlet pipe 74 is connected to the end of the heat exchange cover 7 away from the circulation pump 72 through the liquid outlet connecting pipe 75. Through the circulation pump 72, the coolant flows from top to bottom into the adsorption outer tube 81 through the annular liquid inlet pipe 71, flows from bottom to top into the circulation inner tube 82 at the bottom, and then flows into the heat exchange cover 7 through the annular liquid outlet pipe 74 to circulate and cool again.

[0045] A touch operation panel 91 is provided on the front side of the chassis 1, and an integrated control circuit (not shown) is provided in the touch operation panel 91.

A barcode scanner 92 is provided on the front side of the chassis 1, which is convenient for directly scanning barcodes to identify the types of chemicals for classified recycling.

[0046] Working principle: When in use, the waste chemical reagents are manually inputted using the touch panel, or the barcode on the container is scanned by the barcode scanner 92 to identify the type of chemical. After the identification and classification are completed, the sealing cover 12 on the pouring trough 11 at the corresponding type position is automatically opened, and the waste solution can be poured into the pouring trough 11, and then flow into the separation cylinder 2 along the drainage pipe 21 in the pouring trough 11;

[0047] Then, the horizontal driving motor 32 drives the horizontal sliding sleeve 31 to slide along the horizontal sliding rail 3, so that the ice-making pipe 8 is located above the corresponding separation cylinder 2, and the vertical driving motor 42 drives the vertical sliding sleeve 41 to slide downward along the vertical sliding rail 4, so that the ice-making pipe 8 extends downward into the separation cylinder 2, and the rotating motor 54 drives the mounting plate 51 to rotate, so that the ice-making pipe 8 slowly stirs the waste liquid, and at the same time, the semiconductor refrigeration plate 6 works, and its cold end continuously cools the coolant in the heat exchange cover 7 through the cooling plate 63. Under the action of the circulating pump 72, the coolant continuously circulates between the ice-making pipe 8 and the heat exchange cover 7, so that the ice-making pipe 8 maintains a relatively low temperature. During the stirring process, the water is continuously cooled and frozen on the ice-making pipe 8;

[0048] After the water is fully frozen, the vertical drive motor 42 drives the vertical sliding sleeve 41 to slide upward along the vertical slide rail 4, so that the ice-making pipe 8 drives the ice cubes upward to separate from the separation cylinder 2, the solenoid valve 26 on the negative pressure pipe 23 is opened, and the negative pressure pump 24 is started to suck the concentrated liquid at the bottom of the separation cylinder 2 into the negative pressure tank 22 for temporary storage, and a corresponding container is placed at the corresponding receiving groove 113, and the solenoid valve 26 on the discharge pipe 25 is opened, and the concentrated liquid discharged from the negative pressure tank 22 flows into the container for collection;

[0049] Then the vertical drive motor 42 drives the ice-making tube 8 with ice cubes to extend into the separation cylinder 2 again, and at the same time, a reverse current is passed through the semiconductor refrigeration plate 6 to change the cold end and the hot end of the semiconductor refrigeration plate 6. At this time, the coolant is heated to increase the temperature of the ice-making tube 8, so that the ice cubes fall into the separation cylinder 2, and then the ice-making tube 8 is driven by the rotating motor 54 to rotate and stir the ice cubes to melt the ice cubes and clean the separation cylinder 2. After completion, the water is sucked into the negative pressure tank 22 through the negative pressure pump 24, and finally a corresponding container is placed at the corresponding receiving trough 113, and the solenoid valve 26 on the drain pipe 25 is opened to allow the water in the negative pressure pump 24 to flow into the container through the drain pipe 25, completing a waste liquid concentration and equipment self-cleaning.
