經過濃縮的高溫熔融堿依靠重力經管道流入片堿機弧形鍋，到達一定液面后，粘在片堿機轉鼓上，轉鼓內有循環冷卻水噴頭，熱堿在轉鼓上立即受冷后結晶，通過片堿機另一側的刮刀刮成厚度為0，8~1，2mm的片堿。在開車投料之前，調整刮刀與轉彭的間隙，要求為0，2mm左右;檢查循環冷卻水的流通情況，視生產負荷和片堿成片情況，調整循環水的流量。

The concentrated high-temperature molten alkali flows into the arc-shaped pan of the flake soda machine through the pipeline by gravity. When it reaches a certain liquid level, it sticks to the drum of the flake soda machine. There is a circulating cooling water nozzle in the drum. The hot alkali crystallizes immediately after cooling on the drum and scrapes into flake soda with a thickness of 0, 8~1, 2mm through the scraper on the other side of the flake soda machine. Before start-up and feeding, adjust the clearance between the scraper and the rotary table, which is required to be about 0, 2mm; Check the circulation of circulating cooling water, and adjust the flow of circulating water according to the production load and flake alkali production.

循環水流量過小，轉鼓不能及時降溫，會在轉鼓上形成熔融堿，此時，應立即開大循環水量或者搖下弧形鍋，待轉鼓冷卻，轉鼓上的熔融堿結晶后，用刮刀刮下，再慢慢調小水量或搖上弧形鍋，以防因熔融堿刮下后，再結晶堵塞片堿輸送及包裝系統。

If the circulating water flow is too small, the drum can not be cooled in time, and molten alkali will form on the drum. At this time, immediately increase the circulating water volume or shake down the arc-shaped pot. After the drum is cooled and the molten alkali on the drum crystallizes, scrape it off with a scraper, and then slowly reduce the water volume or shake up the arc-shaped pot, so as to prevent the transportation and packaging system of flake alkali from being blocked by recrystallization after the molten alkali is scraped off.

循環水流量過大，會使熔融堿在剛接觸轉鼓時就立即被冷卻結晶，在轉鼓，上形成大片堿塊，此時，應逐漸關小循環水量，以防大片堿塊進入片堿輸送及包裝系統形成“架橋”現象，堵塞片堿輸送和包裝通道。另外，應及時注意片堿機刮刀的使用情況如果刮刀磨損嚴重，將影響片堿成片和生產能力，應及時更換。

If the circulating water flow is too large, the molten alkali will be cooled and crystallized immediately when it contacts the drum, and large alkali blocks will be formed on the drum. At this time, the circulating water volume should be gradually reduced to prevent large alkali blocks from entering the flake alkali conveying and packaging system to form a "bridge" phenomenon, blocking the flake alkali conveying and packaging channels. In addition, pay attention to the use of the scraper of the flake alkali machine. If the scraper is seriously worn, it will affect the flake alkali production and production capacity, and it should be replaced in time.

此外由于設計上的不足，刮刀的使用壽命很短；片狀KOH的苛性難免使整個生產系統出現設備、管道及水、電、氣等方面的故障，停車的頻率較高。接盛于桶中的堿不但已凝固成堿塊，而且因高溫時接觸空氣，排放管道和接盛容器受到氧化，使接盛的固堿呈黑色，且雜質含量大，只能是廢堿。

In addition, due to the lack of design, the service life of the scraper is very short; The causticity of flake KOH inevitably causes equipment, pipeline, water, electricity, gas and other failures in the whole production system, and the shutdown frequency is high. The alkali contained in the barrel has not only solidified into alkali blocks, but also the discharge pipe and container are oxidized due to contact with air at high temperature, so that the solid alkali contained in the barrel is black and has a large amount of impurities, so it can only be waste alkali.

另外，氫氧化鉀熔融堿冷卻成片過程停車后系統進入了空氣，每次再開車必然先產出大量的黑堿。以前為減少停車次數，曾經帶料處理故障，即在不停止投料的情況下，處理熔鹽爐、包裝秤故障等，尤其是不停車更換刮刀，需幾個小時才能換好。

In addition, after the potassium hydroxide molten alkali cooling process stops, the system enters the air, and a large amount of black alkali will be produced first after each start-up. In the past, in order to reduce the number of stops, we used to deal with the faults with materials, that is, to deal with the faults of molten salt furnace and packaging scale without stopping feeding, especially to replace the scraper without stopping. It takes several hours to replace it.

這期間因無刮刀不能制片，長時間大量排放的熔融堿無法再用桶接盛，只能排人地溝，造成很大的浪費，同時因排放時產生的堿蒸氣溫度高、腐蝕性強，經常損壞主要設備和儀表，并傷害操作人員的皮膚和呼吸道；形成的堿性廢水污染環境，須大量的酸去中和。

During this period, the film cannot be produced without a scraper, and the large amount of molten alkali discharged for a long time cannot be collected in barrels, and can only be discharged into the trench, resulting in great waste. At the same time, the alkali steam generated during discharge has high temperature and strong corrosivity, which often damages the main equipment and instruments, and damages the skin and respiratory tract of operators; The formed alkaline wastewater pollutes the environment and needs to be neutralized with a large amount of acid.
