Problems solved by technology

[0003] The traditional method is to use box-type drying in China. Most of the gas will flow into the air with this drying method. The recovery effect is not ideal and the recovery rate is low.
There are also similar recycling methods in foreign countries, but the related recycling equipment is more expensive, and it is difficult to promote in China
But still do not have a kind of both reasonable cost and efficient ball milling agent recovery method so far

Embodiment Construction

[0016] see figure 1 The ball grinding agent recovery system in the cemented carbide mixed slurry shown includes a vacuum double-cone dryer 1, a filter 2, a tube condenser 3, and a storage tank 4 connected in series. The evacuation tube 11 of the vacuum double-cone dryer 1 communicates with the air inlet of the filter 2, and the air extraction port of the filter 2 communicates with the heat medium channel inlet 31 of the tube condenser 3; the heat medium channel outlet of the tube condenser 3 32 connects the top of storage tank 4. The refrigerant of the tube condenser 3 is chilled water, and the chilled water enters the tube condenser from the inlet 33 of the refrigerant channel and flows out from the outlet 34 of the refrigerant channel.

[0017] The upper part of the storage tank 4 communicates with the suction port 51 of the water ring vacuum pump 5 . The water outlet of the water ring vacuum pump 5 is connected to the upper part of the liquid tank 6, the bottom of the liq...

Abstract

The invention aims to provide a low-cost and high-efficiency method for recycling a ball milled agent in hard alloy mixed slurry. The method comprises the following steps of: heating and drying the hard alloy mixed slurry in a vacuum double-cone drier, and controlling the heating temperature to be about 90 to 110 DEG C so that the ball milled agent in the hard alloy mixed slurry volatilizes into a gas and is vacuumized away by using a vacuumizing tube of the vacuum double-cone drier, wherein the vacuum degree in the vacuum double-cone drier is between -0.04 and 0.06 MPa; and filtering the gas vacuumized by the vacuumizing tube by using a filter and then allowing the gas to enter a condenser and condensing the gas into liquid.

Description

technical field [0001] The invention relates to a method for recovering a ball grinding agent in cemented carbide mixed slurry. Background technique [0002] In modern industry, a large amount of ball milling agent will be added when cemented carbide powder is ball milled in a ball mill, and the cemented carbide powder will become cemented carbide mixed slurry after ball milling. The cemented carbide mixed slurry is mainly composed of cemented carbide powder and ball grinding agent. Since the ball milling agent contains various organic solvents, such as acetone, ethanol and ethane, etc., if these solvents are not recycled in a reasonable way, they will be directly discharged into the atmosphere, which will cause serious environmental pollution, and if they are used in indoor environments Exposure of these flammable gases creates a risk of fire or explosion. Most of these ball milling agents will be recovered in various ways from the perspective of cost and environmental pr...
