Description

Technical Field

[0001] This utility model relates to the field of laboratory technology, and in particular to an emergency adsorption and neutralization device for strong acid and strong alkali leaks in laboratories. Background Technology

[0002] In routine laboratory operations, leaks of strong acids and bases occur frequently. Existing handling methods have several shortcomings. On the one hand, there is a lack of effective adsorption devices, making it difficult to quickly control the spread of the liquid and easily causing damage to the surrounding environment and equipment. On the other hand, neutralization treatment is not sufficient or precise enough to ensure that the leaked liquid meets safety standards. Therefore, we propose an emergency adsorption and neutralization device for strong acid and base leaks in laboratories to solve the aforementioned problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an emergency adsorption and neutralization device for strong acid and alkali leaks in laboratories.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An emergency adsorption and neutralization device for strong acid and strong alkali leaks in a laboratory includes a treatment box, a sealed door on the treatment box, a controller on the sealed door, a fixed box fixedly connected to one side of the treatment box, a placement box slidably connected inside the fixed box for placing absorbent cotton cloth, a placement frame fixedly connected inside the treatment box, multiple through holes at the bottom of the placement frame, and a drain pipe on the rear side of the treatment box.

[0006] The extrusion mechanism, installed on the processing box, is used to extrude the absorbent cotton cloth inside the placement frame.

[0007] The neutralization mechanism, located inside the treatment tank, is used to neutralize the leaked liquid.

[0008] In one possible design, the extrusion mechanism includes an electric push rod and an extrusion plate, the electric push rod being fixedly connected to the top of the processing chamber, and the output end of the electric push rod extending into the processing chamber and being fixedly connected to the top of the extrusion plate.

[0009] In one possible design, the neutralization mechanism includes a drive motor, a stirring shaft, and a pH meter. The drive motor is fixedly connected to one side of the treatment tank via a motor mount. The output shaft of the drive motor is fixedly connected to one end of the stirring shaft via a coupling. The other end of the stirring shaft is rotatably connected to the inner wall of one side of the treatment tank via a bearing. A stirring rod is fixedly connected to the stirring shaft. The pH meter is fixedly connected to one side of the treatment tank, and the detection head of the pH meter extends into the treatment tank. A connecting pipe is fixedly connected to the treatment tank, and a sealing cap is provided at the top of the connecting pipe.

[0010] In one possible design, two telescopic rods are fixedly connected to the top of the processing box, and the bottom ends of the telescopic rods are fixedly connected to the top of the extrusion plate.

[0011] In one possible design, sliders are fixedly connected to both sides of the placement box, and grooves adapted to the sliders are provided on the inner walls of both sides of the fixing box, with the sliders slidably connected in the grooves.

[0012] In one possible design, a fixing plate is fixedly connected to the front side of the placement box, and locking pins are fixedly connected to the four corners of the fixing plate. The fixing box has slots that are compatible with the locking pins.

[0013] In practical use, when a liquid leak occurs in the laboratory, the operator puts on protective clothing beforehand and then pulls the fixing plate. Because the placement box slides within a groove via a slider, it can be easily pulled out of the fixing box. The absorbent cotton cloth inside the placement box is then removed. This absorbent cotton cloth is made of highly efficient liquid-absorbing material and has the ability to quickly absorb strong acid and alkali liquids, thus absorbing the leaked liquid. After absorption is complete, the absorbent cotton is placed in the placement frame, and then the sealing door is closed.

[0014] The controller activates the electric push rod, whose output pushes the extrusion plate downwards. The telescopic rod extends and retracts with the extrusion plate, guiding and stabilizing it to ensure a smooth descent. This extrusion plate squeezes the absorbent cotton cloth, forcing out the absorbed liquid. The liquid flows out through the through-holes in the placement frame and into the treatment tank. A certain amount of water is pre-stored in the treatment tank, serving as a medium for the neutralization reaction.

[0015] Depending on whether the leaked liquid is acidic or alkaline, the operator opens the sealing cap of the connecting pipe and adds the appropriate acidic or alkaline reagent into the treatment tank through the connecting pipe. After addition, the controller starts the drive motor, which drives the stirring shaft and stirring rod to rotate, stirring the liquid in the treatment tank to ensure that the added reagent is fully mixed with the leaked liquid and a neutralization reaction occurs. The pH meter monitors the pH value of the liquid in real time and displays the data on the controller's display screen. When the detected pH value of the liquid meets the standard (usually neutral, with a pH value between 6 and 8), the controller stops the drive motor. At this time, the valve on the drain pipe is opened to drain the neutralized liquid through the drain pipe. Then, the absorbent cloth is further processed, such as centralized collection and disposal in accordance with hazardous waste treatment regulations.

[0016] In this invention, operators do not need to directly touch the leaked strong acid or alkali liquids with their hands to handle the leak. During the adsorption stage, simply pull the fixing plate to pull out the placement box, take out the absorbent cotton cloth to absorb the liquid, and the squeezing and neutralization processes are all carried out in a closed environment inside the treatment box. This greatly reduces the operator's chance of direct contact with hazardous liquids, effectively reducing the safety risks such as skin burns and eye damage caused by contact with strong acids and alkalis, and ensuring the personal safety of the operator.

[0017] In this invention, the neutralization mechanism uses a drive motor to rotate the stirring shaft and stirring rod, thoroughly stirring the liquid in the treatment tank. This ensures that the added acidic or alkaline reagents are evenly mixed with the leaked liquid, guaranteeing a complete neutralization reaction. A pH meter monitors the liquid's pH value in real time, allowing operators to accurately add reagents based on the results until the liquid reaches neutrality. This effectively avoids incomplete or excessive neutralization, improving the quality of leaked liquid treatment.

[0018] This invention not only ensures the safety of operators and reduces the risks of direct contact and untimely protection, but also efficiently adsorbs and precisely neutralizes leaked liquids, improving treatment results. Furthermore, it is easy to operate, made of durable materials, and easy to maintain. It also prevents liquid diffusion, standardizes waste disposal, and achieves environmental protection goals.

The placement frame 2 is made of stainless steel with an anti-corrosion treatment, capable of withstanding the pressure of the extrusion mechanism without reacting chemically with leaked liquids. The drain pipe 3 is made of polyvinyl chloride (PVC), which has good acid and alkali resistance and flexibility, facilitating the drainage of liquids.

[0028] The processing box 1 is rectangular in shape with a sealed door on top. A controller is installed on the sealed door, and the controller has operation buttons and a display screen for controlling various functions of the device and displaying relevant information. One side of the processing box 1 is fixedly connected to the fixing box 4 by welding to ensure a secure connection.

[0029] The fixed box 4 has a hollow internal structure with elongated, smooth grooves 15 on its inner walls on both sides. Sliding blocks 14, rectangular in shape, are fixedly connected to both sides of the placement box 13, fitting into the grooves 15.

The other end of the stirring shaft 8 is rotatably connected to the inner wall of one side of the treatment tank 1 via bearings made of corrosion-resistant material to ensure normal operation in strong acid and alkali environments. Multiple stirring rods are welded to the stirring shaft 8, arranged radially, to stir the liquid in the treatment tank 1, ensuring a more complete neutralization reaction. The pH meter 11 is bolted to one side of the treatment tank 1, with its detection head extending into the tank 1 to monitor the liquid's pH value in real time. A connecting pipe 9 is fixed to the treatment tank 1 via a heat fusion connection. The top of the connecting pipe 9 has a sealing cap, which is threaded to the connecting pipe 9 to ensure a tight seal.
