Description

Energy-saving safety protection table and cabinet structure

technical field

The utility model relates to an exhaust cabinet, in particular to a work desk cabinet used to protect workers from working with substances harmful to the human body or the environment, such as the exhaust cabinet used in a chemical laboratory.

Background technique

Generally, the existing exhaust cabinet structure (as shown in Figure 7 ) that uses chemical substances to prevent the leakage of harmful gases mainly has a wind collecting hood 72 above a desktop 71, and between the desktop 71 and the wind collecting hood 72 Be set as three-sided sealing, one side (the front) is the opening 73 that can be opened to be open, and described an existing exhaust cabinet is provided with a baffle plate 75 in front of its inner wallboard 74 and extends upwards to below the wind collecting hood 72, Make the baffle plate 75 and the inside wallboard 74 and the wind collecting hood 72 have suitable gaps as the passage leading to the exhaust port 76 above the wind collecting hood 72, and then utilize the blower fan 77 located in the exhaust port 76 to draw air. gas, and be connected to the outdoors with a ventilation pipe (omitted in the figure) connected to the exhaust port 76, so that the harmful substances and air produced by the objects working in the exhaust cabinet can be pumped out for safety emission.

As in the above-mentioned existing structure, when the front door panel is opened and is an open space to allow practitioners to operate, it only relies on the suction of the exhaust fan 77 in the exhaust port 76 to draw the air from the outside (indoor outside the exhaust cabinet) It is inhaled through the opening 73, making it in a negative pressure state to prevent harmful air from leaking out; however, in general such an exhaust condition, it will inhale a lot of air outside the exhaust cabinet, that is, the cooling or heating consumption in the laboratory In addition to excessive energy waste, it will form a large-scale backflow structure in the space of the exhaust cabinet, so that a turbulent flow will be formed near the front opening 73, which will further cause harmful substances in the exhaust cabinet. There is a concern about leakage, especially in the hands and chests of practitioners, the turbulent flow and leakage will be more serious; again, the state of air retention will also occur below the horizontal baffle plate 75 at the upper end of the exhaust cabinet, causing it to be exhausted. The exhaust effect is not obvious; secondly, when the objects in the exhaust cabinet have liquid substances or sewage flowing out to pollute the desktop, or when the desktop needs to be replaced due to work needs or damage, the above-mentioned Existing constructions are costly and difficult to clean, wash, and replace with proper tabletop material. Therefore, it is considered that there is a need to study and improve the above-mentioned existing exhaust cabinet structure due to its lack of use.

The designer of the utility model of this case is in view of the fact that the above-mentioned existing exhaust cabinet structure will produce a bad gas flow field during its use, causing harmful substances to leak out, wasting indoor air conditioning (cold/heating) energy, and for cleaning in use Due to the lack of difficulty in maintaining or changing the desktop due to adjustments to the work content, after careful research and years of personal experience in the design and manufacture of the above-mentioned products, a brand-new "energy-saving and safe protection table and cabinet structure" was finally developed and designed. ".

Contents of the invention

The main purpose of the utility model is to provide a kind of energy-saving safety protection table and cabinet structure, and it is to be provided with a removable tabletop at the opening of the upper end of a tray, utilizes the gap (or the hole on the tabletop) between the tabletop and the tray, makes delivery The air entering the tray generates an upward airflow to prevent the harmful gas inside from leaking out. At the same time, the liquid substance or sewage overflowing the table can be collected and discharged by the tray to achieve the effect of safety protection and pollution prevention.

The second purpose of this utility model is to provide an energy-saving and safe protection table and cabinet structure, wherein the gas sent into the tray is extracted to the outside through the air supply pipe or the air supply equipment, or the polluted air is discharged from the exhaust port and recycled through the processing equipment. The source of air supply can reduce the consumption of cooling/heating in the laboratory and achieve the effect of saving energy.

Another object of the present utility model is to provide an energy-saving and safe protection desk and cabinet structure, in which the desktop is designed to be removable, so that it is convenient to replace the desktop and clean the desktop and trays, so as to improve the convenience of use and maintain the cleanliness of the equipment .
