Cleaning equipment Two-way air outlet noise reduction uniform flow balance device and its cleaning equipment

Abstract

The invention discloses a bidirectional air outlet noise-reduction flow-uniformizing balancing device for cleaning equipment and the cleaning equipment. The bidirectional air outlet noise-reduction flow-uniformizing balancing device is characterized in that the balancing device comprises a plurality of balancing modules arranged in parallel and an adjusting mechanism connected with the balancing modules; the balancing modules are arranged close to an air outlet of a fan of the cleaning equipment; each balancing module is provided with an upper cambered air guide plate corresponding to an air discharging port of the cleaning equipment and a lower cambered air guide plate corresponding to an air feeding port of the cleaning equipment; the cambered air guide plates on one side are connected with the adjusting mechanism; the adjusting mechanism moves to adjust the proportion of the opening degree of the balancing modules relative to the air discharging port and the air feeding port. According to the bidirectional air outlet noise-reduction flow-uniformizing balancing device for the cleaning equipment and the cleaning equipment, distribution of the air volume in the equipment is achieved through the angle adjustment of the balancing modules, so that the requirements for the air feeding volume and the air discharging volume are met; meanwhile, noise of the equipment is lowered, the uniformity of air flow in the equipment is improved, and the improvement of the operation performance of the equipment is facilitated.

Description

technical field [0001] The invention relates to the field of biological safety, in particular to a two-way air outlet, noise reduction and uniform flow balance device for cleaning equipment, which is used to adjust the ratio of air supply and exhaust in the equipment. Background technique [0002] Biosafety generally refers to the potential threats to the ecological environment and human health caused by the development and application of modern biotechnology, and a series of effective prevention and control measures taken against them. With the entry of biotechnology and genetic engineering products into our daily life, such as genetically modified food, amino acids, vitamins, drugs, genetically modified cotton to wear, various genetically engineered enzyme preparations, thickeners, organic acids, Emulsifiers, etc. are all infiltrated with the role of genetic engineering, which actually involves biological safety issues. [0003] Biosafety is divided into levels 1 to 4 in ...

AI Technical Summary

Problems solved by technology

In biosafety laboratories, the equipment used is usually clean equipment. This type of equipment has specific requirements for the control of space air volume. For example, the matching of air supply volume and exhaust air volume of biological safety cabinets requires 720m 3 / h (send) 400m 3 / h(row)~1150m 3 / h (send) 635m 3 / h (row), but due to various reasons such as internal air duct structure and individual differences in filters, it is difficult to match the actual air supply volume and exhaust air volume, and it is difficult to achieve the ideal ratio

[0004] To solve the above problems, we usually think of using pipes or devices to adjust the air volume to control the air volume. However, due to the limitation of the internal space of the safety cabinet, it is not easy to install an air volume control device. Therefore, the current structure cannot fully meet the requirements and needs further improvement.
