令和6年の地震や豪雨災害の早い復興を願います。 私の趣味はDIYを楽しむ事 小さな物から大きな物まで修理や作成しています。 (写真:梅津正道隊員撮影) I wish for a swift recovery from the earthquake and heavy rain disasters of 2024. My hobby is enjoying DIY, repairing and creating things from small to large. (Photo: Taken by Masamichi Umezu)
The back side is tape, so it was easy to tape it to the back of the board wall. That being said, it’s a job that requires only your fingertips to stick it in a small space.
The purpose of making it was to conduct an experiment to see if it could effectively collect the diatomaceous earth dust that is often found at part-time jobs.
これが、珪藻土粉です。This is diatomaceous earth powder.
吸うには吸いますが、吸ったとたんにタンク内が粉だらけになり何も見えなくなります。
As soon as you smoke, the inside of the tank becomes full of powder and you can’t see anything.
Powder accumulates in the tank, but it reaches the air pump filter. Debris other than powder remains in the tank, but powder in smoke form seems to be sucked out of the tank.
右に突き出た小さいペットボトルがフィルターです。The small plastic bottle that sticks out to the right is the filter.
Once, when we conducted a powder suction experiment, the powder accumulated in the folds of the bellows of the white hose and did not reach the dust collector. Rebuild by changing the hose to one without bellows. to be continued
The basic configuration is the same, but the tank is shaped like two containers of seasoned seaweed connected together, and the inner diameter of the hoses has been increased from 14 mm to 32 mm. It turns out that there are no hoses without bellows. It seems that a lightweight hose must have a bellows structure or coil to ensure strength, so we decided to increase the hose diameter. I would like to experiment with this. to be continued

フィルターを廃材プラ容器を利用して高さを低く変更してみました。
I tried lowering the height of the filter by using a waste plastic container.

左がフィルター、右が集塵タンク。The filter is on the left, and the dust collection tank is on the right.
ホースとフィルターはペットボトルをバーナーで加熱して収縮させたもの。
The hose and filter are made by heating a plastic bottle with a burner and shrinking it.
さー実験で珪藻土の粉を吸ってみました。
As an experiment, I tried smoking diatomaceous earth powder.
集塵タンク入り口は粉がへばり付いています。The entrance to the dust collection tank is caked with powder.
タンク内部は壁面がかなり汚れています。The walls inside the tank are quite dirty.
衝撃を与えると落ちてきました。It fell when I gave it a shock.
タンク下部 薄茶色の物が粉。糸くずみたいな物は以前吸ったペットボトルの削りカス。
At the bottom of the tank, the light brown substance is powder. The lint-like thing is shavings from a plastic bottle I used to smoke.
空気ポンプからフィルターを外しました。I removed the filter from the air pump.
更にフィルターを抜き取ると、こんな感じです。
真っ白だったフィルターは粉まみれです。タンクでキャッチ出来なかったものが、ここまで来ています。
The filter, which was pure white, is now covered in powder. What we couldn’t catch in the tank is now here.
衝撃を与えても、この程度しか落ちません。フィルターは水洗いが必要です。
Even if you give it a shock, it will only fall by this amount. The filter needs to be washed with water.
ポンプ入り口にも薄っすらと粉が着いています。
There is also a thin layer of powder at the pump entrance.
There is also powder stuck to the inner wall of the suction hose. The conclusion was that general dirt can be captured in the dust collection section, but about 30% of powder passes through the cyclone section. It seems to be okay for anything other than powdery materials such as wood shavings.
