Description

Technical Field

[0001] The utility model belongs to the technical field of spirulina powder processing, in particular to an air filtering device for a spirulina powder processing workshop. Background Art

[0002] Spirulina powder is made from fresh spirulina through spray drying, sieving and sterilization. It can be divided into feed grade, food grade and special purpose according to different uses. Feed grade spirulina powder is generally used in aquaculture and livestock farming, while food grade spirulina powder is used in health food and added to other foods for human consumption. During the production and processing of spirulina powder, the air in the processing workshop will be mixed with spirulina powder. In order to avoid the waste of spirulina powder and the pollution of the atmospheric environment, air filtration devices are usually installed in the processing workshop.

[0003] The existing document with publication number CN209092941U discloses an air filter device for a microalgae powder processing workshop, comprising a body, an air inlet pipe is fixedly connected to the right side of the body, an air outlet pipe is fixedly connected to the left side of the body, an air pump is fixedly connected to the inner wall at the bottom of the air inlet pipe, an air inlet end on the right side of the air pump is fixedly connected to the air inlet pipe, an air outlet end on the left side of the air pump is fixedly connected to the input pipe, and two symmetrical filter screens are fixedly connected to the inner walls of the top and bottom of the body through limit springs;

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the above-mentioned air filter device, two symmetrical filter screens are fixedly connected to the inner walls of the top and bottom of the body through limit springs, and a cleaning tooth plate is also provided on one side of the filter screen. However, since the filter screen is installed through the limit spring, the filter screen is displaced under the action of the airflow, and the filter screen is separated from the cleaning tooth plate. At this time, the cleaning tooth plate cannot complete the cleaning work of the filter screen;

[0006] 2.
