Equipment and method used for solid particle or solid-liquid mixture washing and purification

Abstract

The invention discloses equipment and a method used for solid particle or solid-liquid mixture washing and purification. The equipment comprises a tank body, a spray device, an overturning device and a limit switch; the spray device is arranged above the tank body; a filter layer is arranged in the tank body, a filtrate chamber is arranged below the filter layer, and a liquid drain hole is formed in the bottom of the filtrate chamber; a rotating shaft is arranged at the bottom of the tank body, and the bottom of the tank body is connected with the overturning device; the limit switch is arranged on the tank body or overturning device. The method includes that (1) filtering, to be specific, placing solid-liquid mixture on the filter layer, wherein the liquid enters the filtrate chamber through the filter layer and is drained through the liquid drain hole; (2) spray washing, to be specific, carrying out spray washing on solid granular material or the filter cake of the step (1); (3) water controlling and draining, to be specific, carrying out water controlling and draining on the washed solid granular material or filter cake; (4) overturning to discharge material, to be specific, starting the overturning device to discharge the solid granular material or filter cake from the tank. The equipment cost is low; the method is short in flow, high in automatic degree and high in washed product purity.

Description

technical field [0001] The invention relates to a purification equipment and method, in particular to a purification equipment and method for solid particles or solid-liquid mixture. Background technique [0002] In actual production, there are many products that need to improve their purity, such as most inorganic salts and a small amount of organic products. The traditional equipment for washing solid-liquid mixture generally adopts the pump plus centrifuge system, but the amount of washing liquid (or washing water) in the centrifuge is small, the washing and purification effect is limited, and it is difficult to meet the high purity requirements of the product. Traditional equipment for solid washing generally uses a washing tank plus a pump and a centrifuge. However, if the amount of washing liquid added to the washing tank is too large, the concentration of the material will be too low, which will affect the normal operation of the centrifuge. On the contrary, if the am...

The traditional equipment for solid-liquid mixture washing generally adopts the pump plus centrifuge system, but the amount of washing liquid (or washing water) in the centrifuge is small, the washing and purification effect is limited, and it is difficult to meet the high purity requirements of the product

Traditional equipment for solid washing generally uses a washing tank plus a pump and a centrifuge. However, if the amount of washing liquid added to the washing tank is too large, the concentration of the material will be too low, which will affect the normal operation of the centrifuge. On the contrary, if the amount of washing liquid added is small, the washing effect will be poor.

The above-mentioned solid and solid-liquid mixture washing and purification equipment has a long process, high cost and limited washing effect
