Description

Technical Field

[0001] This utility model relates to the technical field of laboratory equipment, specifically to a laboratory odor elimination device. Background Technology

[0002] A laboratory is a place where experiments are conducted. During the experiments, some odors are generated, most of which are pungent and unpleasant, causing discomfort to the experimenters. Therefore, odor elimination devices are often used to remove the odors.

[0003] Existing odor elimination devices generally consist of a collection system and a filtration system. The collection system comprises ventilation ducts and an exhaust fan, while the filtration system consists of a filter screen and activated carbon structure. The filter screen and activated carbon structure, designed within the ventilation duct, filter and adsorb suspended solids and odors in the inhaled air, then return the deodorized air to the laboratory to achieve the purpose of odor removal. However, this system has the following shortcomings:

[0004] 1. After long-term use, large particles of suspended matter will adhere to the surface of the filter, affecting ventilation efficiency, i.e., the efficiency of odor removal.

[0005] 2. The adsorption capacity of activated carbon structures is limited, requiring frequent replacement. Furthermore, activated carbon structures are installed inside ventilation ducts, making replacement inconvenient. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] As attached Figure 1-4 As shown, a laboratory odor elimination device includes a ventilation duct 1. One end of the ventilation duct 1 is equipped with an exhaust fan 2, and the other end is fitted with a removable filter screen 3. An activated carbon block 4 is inserted into the end of the ventilation duct 1 where the filter screen 3 is located. By filtering and adsorbing suspended matter and odors in the inhaled air through the filter screen 3 and activated carbon block 4 designed at one end of the ventilation duct 1, the deodorized air is then sent back to the laboratory through the exhaust fan 2 to achieve the purpose of removing odors.

[0028] The ventilation duct 1 is a U-shaped structure and is made of corrosion-resistant metal. The U-shaped structure allows the gas with a strong odor to be directly discharged back into the laboratory from the other end.

[0029] The exhaust fan 2 includes a rectangular frame connected to the ventilation duct 1. The front side of the rectangular frame is provided with multiple railings. The front side of the railings is provided with a motor. The motor passes through the railings and is connected to a rotating rod. The side wall of the rotating rod is evenly provided with multiple fan blades along the circumferential direction. The exhaust fan 2 is fixed to the exhaust end of the ventilation duct 1 and is used to drive airflow and increase the circulation of gas in the laboratory.

[0030] The filter screen 3 is sleeved on one end of the ventilation duct 1. The filter screen 3 is attached to the ring body of the ventilation duct 1 and the filter plate at the front end of the ring body. The filter plate is used to filter large suspended particles. The inner wall of the ring body is provided with corresponding grooves 6. The side wall of the ventilation duct 1 is provided with connecting blocks 7 that cooperate with the grooves 6. The connecting blocks 7 are made of rubber, so that the filter screen 3 is sleeved on the ventilation duct 1. The connecting blocks 7 on the ventilation duct 1 are inserted into the grooves 6 to fix their position, making it convenient to install and disassemble the filter screen 3.

[0031] The ventilation duct 1 is equipped with a limiting ring 5 that cooperates with the activated carbon block 4. The limiting ring 5 is welded inside the ventilation duct 1 to limit the insertion depth of the activated carbon block 4. The front end of the activated carbon block 4 is connected to a traction rope 8 that extends out of the filter screen 3. When replacing, the activated carbon block 4 can be pulled out of the duct by pulling the traction rope 8, which is convenient for disassembly.

[0032] In practical use, the exhaust fan 2 is turned on, and the motor drives the fan blades to rotate, drawing odor-laden air from the laboratory into the ventilation duct 1. When the air passes through the filter screen 3, large particulate matter is intercepted on the surface of the filter screen. The airflow passes through the activated carbon block 4, where odor molecules are adsorbed. The purified air returns to the laboratory through the U-shaped pipe. The filter screen 3 and activated carbon block 4 are easy to disassemble, avoiding long-term accumulation of dirt that affects ventilation efficiency and the failure of activated carbon block 4. This allows the device to maintain efficient odor removal operations and quickly eliminate odors in the laboratory.
