Buffer tank

Abstract

The invention provides a buffer tank and belongs to turnover equipment for processing neodymium iron boron wastes. The buffer tank can be used for solving the defect that the sealing element of the buffer tank is burnt because a centrifugal pump idles when the feed liquid is drained in the prior art. The buffer tank mainly comprises a tank body, wherein the tank body is provided with a water feeding pipe and a water outlet, and the water feeding pipe is provided with a water inlet and a control valve. The buffer tank is mainly used for turning over the neodymium iron boron wastes in chemical plants.

Description

technical field [0001] The invention belongs to a turnover equipment for NdFeB waste treatment, in particular to a buffer tank used for NdFeB waste treatment. Background technique [0002] NdFeB is a permanent magnet material with superior performance, which is widely used in various high-tech fields. Due to the production process and use factors, about 20% of waste will be generated during production and use. NdFeB materials contain about 30% of rare earth elements (of which neodymium accounts for about 90%, and the rest are terbium, dysprosium, etc.), and some NdFeB materials also contain about 3% of cobalt elements. The recycling of NdFeB waste not only makes reasonable use of resources, but also reduces environmental pollution. [0003] In the existing processing technology, it is often necessary to turn over the NdFeB material solution in the workshop. Generally, a centrifugal pump is directly used to extract the feed liquid. When the feed liquid is drained, the centr...
