Air shower filtering device and air shower

Abstract

The invention discloses an air shower filtering device and an air shower. The air shower filtering device comprises an air outlet, a filter and a cavity; the upper edge of the air outlet is provided with a conical section which is connected with a sealing ring; the filter is of a hollow cylinder structure with the upper end being sealed and the lower end being open; the lower end of the filter isprovided with a conical hole of the same conical corner as the conical section; the conical hole is used for being connected with the conical section; the filter is arranged in the cavity; the cavityis hinged to a side door; fixing frames for being connected with the side portion of the filter are arranged inside the cavity and the side door; and the cavity is provided with a first lug plate, theside door is provided with a second lug plate, and the first lug plate is connected with the second lug plate when the side door covers the cavity. The conical section, the sealing ring and the conical hole can prevent airflow from being leaked between the air outlet and the filter, an air outlet lug plate is connected with a screw rod, airtightness between the air outlet lug plate and the screwrod can be further improved, and the fixing frames inside the side door and the cavity can fix the filter to prevent the filter from tilting.

Description

technical field [0001] The invention relates to an air shower filter device and the air shower, belonging to the technical field of sterilization and dust removal. Background technique [0002] The air shower room is usually set at the entrance and exit of the clean room. Its function is to blow off the dust and debris on the entrants and prevent the entrants from bringing dust into the interior of the clean room. For some workshops with a large flow of people, the frequency of use of the air shower is relatively high. The built-in air filter device in the air shower ensures that the outflowing air should be as fresh as possible. Therefore, for a 24-hour production workshop, the air shower requires other It is in working condition all the year round, and the air filter device inside the air shower room needs to be replaced regularly. The existing air filter device has two defects. On the other hand, the existing air filter device also has the problem of slow replacement spe...

For some workshops with a large flow of people, the frequency of use of the air shower is high. The built-in air filter device in the air shower ensures that the air flowing out should be as fresh as possible. Therefore, for a 24-hour production workshop, the air shower requires other Being in working condition all the year round, the air filter inside the air shower room needs to be replaced regularly. The existing air filter has two defects. On the other hand, the existing air filter device also has the problem of slow replacement due to its complex structure and many connecting parts.
