Description

Technical Field

[0001] The utility model relates to the field of ventilation equipment, in particular to an air duct structure for supplying air to a laboratory. Background Art

[0002] The cleanliness of the laboratory environment is crucial to the accuracy and reliability of experimental results. To ensure the air quality in the laboratory, the laboratory generally uses a simple fan for ventilation, and at the same time filters and disinfects the air;

[0003] Existing laboratory air treatment systems usually rely on relatively complex air duct structures and filter chamber designs to achieve effective filtration and disinfection of the air. In these systems, the filter element in the filter chamber is a key component, but its replacement process is often not convenient enough. Specifically, the design of many systems makes the filter element replacement process complicated and time-consuming, requiring professional personnel to operate, which not only increases the difficulty of maintenance, but may also lead to extended system downtime, thereby affecting the normal operation of the laboratory. In addition, traditionally designed filter chambers usually lack sufficient space or mechanisms to simplify the filter element replacement process, which forces users to disassemble a large number of components when replacing, resulting in additional labor and time costs. At the same time, traditionally designed filter chambers only perform filtering and cannot perform disinfection. Utility Model Content

[0004] The purpose of the utility model is to provide a laboratory air supply duct structure with a simple structure and convenient installation, which can disinfect and filter the air sent into the laboratory through a filter chamber, and at the same time greatly increase the air intake volume by setting a conical air guide cover.

[0005] The utility model is achieved through the following measures:

[0006] A laboratory air supply duct structure includes a fan and an air inlet duct arranged at the air inlet end of the fan, wherein a filter chamber is provided on one side of the fan, and the filter chamber is connected to the air outlet port of the fan through a duct;

[0007] The filter chamber comprises a rectangular hollow chamber that passes through the upper and lower ends of the rectangular hollow chamber, an upper conical chamber body and a lower conical chamber body are respectively provided at the upper and lower ends of the rectangular hollow chamber, the top end of the upper conical chamber body is connected to the air outlet port of the fan through a pipe, and the bottom end of the lower conical chamber body is provided with an air supply pipe;

[0008] A plurality of ultraviolet disinfection lamps are arranged inside the upper conical warehouse body and the lower conical warehouse body;

[0009] Several layers of filter elements are arranged in the rectangular hollow chamber.

[0010] The specific features of the utility model also include:

[0011] A rectangular opening is provided on one side wall of the rectangular hollow chamber, and a sealing cover is provided on the outer side of the rectangular opening and on the rectangular hollow chamber;

[0012] Several groups of corresponding L-shaped support plates are arranged on both sides of the rectangular opening and on the inner wall of the rectangular hollow chamber, and filter elements are arranged on the L-shaped support plates at the same horizontal position.

[0013] The filter element adopts a filter element commonly found on the market with a rectangular frame on the outside.

[0014] A conical air guide cover is provided inside the air inlet duct, and the narrow air outlet end of the conical air guide cover is provided close to one side of the fan;

[0015] A pair of side air inlet pipes are symmetrically arranged on one side of the narrow air outlet end of the conical air guide cover and on both sides of the outer wall of the air inlet duct;

[0016] By setting up the conical air guide cover, when the air flow passes through the conical air guide cover, low pressure is formed near the conical air guide cover. Through the principle of low-pressure adsorption, the air in the external environment is sucked in through the side air inlet pipe and finally enters the room, thereby increasing the final delivery capacity of the fan and achieving energy-saving effects.

[0017] The side air inlet pipe and the end of the air inlet duct are both provided with protective covers.

[0018] An annular baffle is provided on the inner side of the bottom edge of the upper conical bin body, and an elastic cushion layer is provided on the bottom of the annular baffle.

[0019] The side walls of the rectangular hollow bin are provided with a plurality of supporting legs.

[0020] During ventilation, the fan works, and the external air enters the ventilation duct of the laboratory after preliminary disinfection and filtration through the filter bin. When the filter element of the filter bin is replaced, the fan corresponding to the filter bin of the filter element to be replaced stops working, the sealing cover is opened, the old filter element is taken out, and a new filter element is replaced. During replacement, the outer shell of the top filter element is tightly against the elastic cushion layer at the bottom of the annular baffle, thereby ensuring that the air entering the filter bin is completely filtered, and preventing the air from entering the ventilation duct through the gap at the edge of the filter element without being filtered.

[0021] The beneficial effects of the utility model are: simple structure, convenient installation, disinfection and filtration of the air sent into the laboratory through the filter chamber, and greatly increased air intake by setting the conical air guide cover. BRIEF DESCRIPTION OF THE DRAWINGS
