鑄工車間的廢砂运出,新砂运入,以及新砂的長期貯存,都会导致鑄件成本增高,在离砂产地远的工厂,就显得更为突出。另一方面,自从大躍进以来,各厂的产量都在成倍地增加,造型原材料——型砂的需要量也相应地增加。因此,型砂的供应就比較紧張。有些工厂常常因为型砂供应不上,使得車間不能保持正常的生产。再一方面,从目前情况来看,在型砂再生方面各厂都想出一些办法,例如青島四方机車厂鑄鋼車間和上海机修总厂等都已安裝了水洗型砂的裝置,然而都存在着一定的缺点。所以,目前急需一些結構簡單而实用的型砂再生設备。为了解决这个問題,我們第一設計院設計了一套型砂干法再生設备。这套設备的結構很簡單,經过試驗,証明效果很好, Casting workshop waste sand shipped out, the new sand into the new sand and long-term storage, will lead to higher casting costs, far away from the sand in the factory, it becomes even more prominent. On the other hand, the output of each factory has doubled since the Great Leap Forward, and the demand for molding raw material, sand, has also correspondingly increased. Therefore, the supply of sand is more nervous. Some factories often do not provide sand because the sand, making the workshop can not maintain normal production. On the other hand, judging from the current situation, various plants have come up with some measures for the recycling of molding sand. For example, the equipment for washing sand has been installed in the steel plant of Qingdao Sifang Locomotive Works and Shanghai Machinery Repair Plant, etc. However, Certain shortcomings. Therefore, the urgent need for some simple and practical structural sand recycling equipment. In order to solve this problem, our first design institute designed a set of sand dry regeneration equipment. The structure of this device is very simple, after testing, proved effective,
