Embodiment Construction
[0023] The present invention will be further described below in conjunction with accompanying drawing:
[0024] Such as figure 1 , 2 As shown, a method of recovering forming agent from dewaxing gas is to open a circuitous air passage on the condensation recovery container for recovering forming agent in dewaxing gas, so as to increase the cooling and condensation stroke to improve the recovery of forming agent in dewaxing gas efficiency. The existing dewaxing treatment method is to pass the dewaxing gas into the tank body from one end of a recumbent tank body, and briefly condense the forming agent in the dewaxing gas in the tank body from the other side of the tank body. The tail gas pipe 12 provided at one end is discharged. Due to the limited length of the tank body, the recovery rate of the forming agent in the dewaxing gas is less than 50%. However, with this method, the recovery efficiency of the forming agent in the dewaxing gas is significantly improved, reaching mo...

The invention discloses a method for recovering a forming agent from dewaxing gas and a recovery device implementing the method. According to the method, a circuitous air passage is arranged in a condensation recovery container tank for recovering the forming agent from the dewaxing gas, so that the recovery efficiency of the forming agent in the dewaxing gas is increased by increasing the coolingcoagulation stroke. The device comprises a transverse tank, wherein an air inlet pipe and an exhaust pipe are respectively arranged at the front section and the rear section of the transverse tank; aforward vertical pipe and a return vertical pipe which communicate with the transverse tank are respectively arranged at the front section and the rear section of the transverse tank; a communicatingpipe is arranged at the top end of the forward vertical pipe and the top end of the return vertical pipe and is used for communicating the forward vertical pipe and the return vertical pipe into a circuitous pipe; ports, which are arranged in the transverse tank, in the lower end of the forward vertical pipe and the lower end of the return vertical pipe are an air inlet and an air return port ofthe circuitous pipe respectively; and a transverse partition board is arranged in the middle of the transverse tank. The method and the device have the advantages that the recovery rate of the formingagent in the dewaxing gas is increased from less than 50% of the prior art to above 98%-80%, the dewaxing effect of sintered products can be accurately judged, and the later environmental protectiontreatment is facilitated.
Description
technical field [0001] The invention relates to dewaxing equipment for removing impurities such as forming agents after cemented carbide sintering, in particular to a device for recovering forming agents from dewaxing gas in the dewaxing equipment, belonging to the technical field of cemented carbide sintering equipment. Background technique [0002] In the field of cemented carbide sintering equipment, due to the diversified needs of the dewaxing sintering process, to ensure the quality stability of sintered products, it is necessary to remove the forming agent from the sintered cemented carbide through dewaxing equipment. Also commonly referred to in the industry as dewaxing. How to judge whether the forming agent is completely removed, the most direct and accurate method is to judge how much forming agent can be captured and recovered by the water-soluble forming agent recovery device in the dewaxing equipment. However, affected by the device for capturing and recovering...
