A high-efficiency hydrocyclone with combined structure used in potash fertilizer production

Abstract

The invention relates to a combined structure type efficient hydrocyclone used for potassium fertilizer production. The hydrocyclone comprises an overflow pipe, a cylindrical section, a combined structure outside the overflow pipe and at the lower end of the overflow pipe, a conical section, a feeding pipe and an underflow pipe, wherein the feeding pipe is connected with the cylindrical section in a welding manner; the cylindrical section is in threaded connection with the conical section; the conical section is in the threaded connection with the underflow pipe; a compression sleeve is fixed on the underflow pipe through a thread on the compression sleeve; the combined structure is connected with the overflow pipe in the welding manner; and the interior of the combined structure is fixed with the exterior of the overflow pipe through a welding rod. According to the hydrocyclone, the effects of improving the separation efficiency and reducing the energy consumption in the reverse flotation-cold crystallization production process of a potassium fertilizer can be achieved through simple structural modification. The hydrocyclone is compact in structure, convenient to implement, economic and reliable.

Description

【Technical field】 [0001] The invention relates to the technical field of cyclone equipment, in particular to a high-efficiency hydrocyclone with combined structure used in potash fertilizer production. 【Background technique】 [0002] So far, the application of hydrocyclones has a history of more than 100 years, and the first hydrocyclone patent was applied by Bretney in the US patent. In 1914, the hydrocyclone was officially applied to the industrial production of phosphate fertilizer. But it did not appear in commercial form for water treatment in the pulp industry until the late 1930s. In 1943, Tepef and Woods of the US Atomic Energy Commission used hydrocyclones for the separation of ether-water systems. After the hydrocyclone was used to remove water from the oil, a large number of literature on the hydrocyclone began to appear, and the hydrocyclone has become a standard solid-liquid separation equipment at this time. [0003] The reason why hydrocyclones are so widel...
