刮板除渣機(jī)主要用于從液體與固體混合物中將符合一定粒度的固體物質(zhì)分離出來。是一種連續(xù)、高效的機(jī)械式除渣設(shè)備，常用于分選或固液分離的場合。如：鍋爐排渣系統(tǒng)，河流挖取沙系統(tǒng)等等。中國第一臺刮板除渣機(jī)誕生于1987年，用于電力鍋爐排渣。

The scraper slag remover is mainly used for separating solid substances with a certain size from liquid and solid mixtures. It is a continuous and efficient mechanical slag removal equipment, often used in separation or solid-liquid separation occasions. Such as: boiler slag discharge system, river dredging system and so on. China’s first scraper slag removal machine was born in 1987, used for slag removal of power boilers.

Structure

刮板除渣機(jī)機(jī)構(gòu)造簡單、速度較慢，一般不超過是3m/min，但是因?yàn)闋恳湕l和刮板是直接在槽底滑動，所以不僅阻力大，而且磨損也是比較嚴(yán)重；另外，當(dāng)鍋爐燃用含硫較高的煤種時，鏈條和刮板還要受到腐蝕。所以，刮板和鏈條要耐磨，耐腐蝕的材料做成，并要有一定的強(qiáng)度和剛性，以免有大顆粒的渣塊落下卡住時被拉彎或者扯斷。

The mechanism of scraper slag removal machine is simple and slow, generally not more than 3m/min, but because the traction chain and scraper are sliding directly at the bottom of the groove, it not only has great resistance, but also has serious wear and tear. In addition, when the boiler burns coal with high sulfur content, the chain and scraper will be corroded. Therefore, scrapers and chains should be made of wear-resistant, corrosion-resistant materials, and have a certain strength and rigidity, so as to avoid large particles of slag falling and stuck when pulled or broken.
