Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of experimental protection, specifically to a protective device for chemical experiments. Background Technology
[0002] Experimentation is one of the fundamental methods of scientific research. Based on the purpose of scientific research, it involves minimizing external influences, highlighting key factors, and utilizing specialized instruments and equipment to artificially alter, control, or simulate the research object, causing certain things (or processes) to occur or be reproduced, thereby understanding natural phenomena, natural properties, and natural laws. Chemical experiments are also an important part of teaching, and to avoid potential dangers during experiments, protective equipment is required.
[0003] Existing experimental protective equipment is mostly wearable personal protective equipment. Traditional chemical operation benches, in order to ensure operational safety, are mostly covered by protective covers around the perimeter. However, in actual operation, they cannot be well adjusted for different experimental operations, resulting in limited experimental space, which is not conducive to experimental personnel to carry out experiments. At the same time, it is difficult to effectively treat harmful gases generated during the experiment. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a protective device for chemical experiments that can solve the following problems:
[0005] Traditional chemical workbenches cannot be easily adjusted for different experimental operations, resulting in limited experimental space, which is not conducive to experimental operations. At the same time, it is difficult to effectively deal with harmful gases generated during the experiment.
[0006] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:
[0007] A protective device for chemical experiments includes a fixedly connected operating table and a support plate. A fan mechanism is fixedly connected to the top of the support plate. A protective component and an adsorption component are fixedly connected to the surface of the operating table. The protective component includes a matching protective plate and a vertical part. An inner protective layer is flipped and connected to the inner side of the protective plate. A limit groove is provided on the surface of the operating table. The adsorption component includes a fixedly connected baffle and an adsorption hood. A flow guide grid is embedded in the surface of the adsorption hood. A matching inner adsorption layer and an inner filling layer are embedded in the interior of the adsorption hood.
[0008] Furthermore, the limiting groove is opened along the surface of the operating table, which includes multiple sets of interconnected rectangular grooves, and its surface is provided with anti-slip particles. The anti-slip particles are made of corrosion-resistant silicone rubber particles with a height of 1-3mm and a base thickness of 2-5mm. They are adhered to the surface of the limiting groove with adhesive backing.
[0009] Furthermore, the limiting groove is opened on the rear surface near the surface of the operating table.
[0010] Furthermore, both the protective plate and the inner protective layer are made of PMMA high-transparency board. The arc radius of the protective plate is set to ≥300mm, and the thickness is selected to be 4-8mm. Its edges are covered with soft rubber strips, and the outer sides of the inner protective layer and the outer sides of the protective plate are connected by a shaft flipping.
[0011] Furthermore, the inner surface of the protective panel is coated with a permanent anti-fog coating, located in the center of the front of the control panel, with the bottom of the vertical part movably embedded into the edge surface of the front of the control panel.
[0012] Furthermore, two sets of baffles are arranged in an "L" shape along the rear corner of the operating table, and the adsorption hood is located between the two sets of baffles. The overall structure is arranged in an arc shape laterally, and semi-enclosed baffles are provided at both ends of the adsorption hood.
[0013] Furthermore, the adsorption hood is hollow and has an arc-shaped inner cavity. The arc-shaped inner cavity and the fan mechanism are connected by a pipe. A silicone sealing strip is installed between the bottom edge of the adsorption hood and the operating table. Adsorption holes with a diameter of 5-10mm are evenly opened on its inner surface. An adjustable air valve is also installed in the adsorption hole.
[0014] Furthermore, the inner adsorption layer and the inner filling layer are integrally set, with the surface of the inner adsorption layer set as an activated carbon adsorption layer, and the inner filling layer set as an activated carbon particle filling layer, both located in the arc-shaped inner cavity of the adsorption hood.
[0015] Furthermore, the flow guide grille is set in an arc shape along the inner surface of the adsorption hood, and it is made of PP grille. It and the surface of the adsorption hood are set with quick-release buckles for installation.
[0016] Furthermore, the flow guide grille has a aperture of 6-9mm and a thickness of 4mm, and its grille blades are set at an inclination of 15-30°.
[0017] As can be seen from the above technical solution, the beneficial effects of this utility model are:
[0018] 1. This utility model, through the limiting groove and its surface anti-slip particles, achieves the effect of limiting the placement of external test tubes or reagent glass bottles, and at the same time can prevent the reagents from being spilled onto the operating table.
[0019] 2. This utility model achieves the effect of protecting and covering the experimental operation process from the front and inside through the protective plate and the inner protective layer that can be flipped and adjusted. At the same time, it facilitates the experimenter to perform visual operation of the experimental process. Its arc radius can effectively avoid excessive bending that could cause optical distortion, and the edges can effectively prevent cuts. The vertical part that is inserted into the operating table facilitates the quick assembly and disassembly of the entire protective component and emergency handling.
