Problems solved by technology

However, this kind of dewaxing kettle has some shortcomings. The heating method of the heating tube is slow, the efficiency is low, and the power consumption is large. Management is cumbersome
After dewaxing in the common dewaxing kettle, the mixture of wax liquid and water is released from the dewaxing kettle. To recycle the wax, it needs to go through a separate water removal process, and the wax in the dewaxing kettle can only rely on gravity after opening the valve. flow out

Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing.

[0010] refer to figure 1 , High-frequency induction dewaxing and wax-water separation dewaxing kettle includes 1-kettle door, 4-dewaxing chamber, 6-dewaxing chamber intake control valve, 9-steam generating tank induction coil, 10-wax pump, 11-heating and dewatering induction coil, 14-steam generating tank.

[0011] The steam generating tank is welded by a cylinder made of carbon steel and a head, and a water inlet and a water outlet are left under the steam generating tank. 7-steam generating tank temperature sensor, 8-steam generating tank safety valve are installed above the steam generating tank. The outer layer of the steam generation tank is wrapped with thermal insulation material to reduce heat loss, and the outer thermal insulation material is evenly wound with 9-steam generation tank induction coils.

[0012] The 4-dewaxing chamber is welded together with the 14...

Abstract

The invention discloses a high-frequency induction type dewaxing kettle with a wax-water separation function. According to the technical scheme, the high-frequency induction type dewaxing kettle comprises a steam generating tank, a dewaxing cavity, a steam inlet control valve, aluminum silicate heat preservation materials and a high-frequency induction heating device. The steam generating tank communicates with the dewaxing cavity through the steam inlet control valve, and steam is controlled by the steam inlet control valve to enter the dewaxing cavity. The corresponding aluminum silicate heat preservation material is arranged on the outer layer of the steam generating tank. A high-frequency electromagnetic induction coil is evenly wound on the heat preservation material. The dewaxing cavity is also covered with the corresponding aluminum silicate heat preservation material. A high-frequency electromagnetic induction coil is arranged below the dewaxing cavity and used for heating the dewaxing cavity so as to separate water. An exhaust valve is arranged on the dewaxing cavity and used for exhausting water steam when the pressure is reached. A wax pumping device is connected with a wax outlet of the dewaxing cavity. The dewaxing kettle is heated through the electromagnetic induction principle, the heating speed is high, the heating efficiency is high, the dewaxing kettle has the rapid water removing function, so that further treatment of wax liquid is omitted, and after being pumped into a standing barrel through the wax pumping device and then is subjected to standing, the dewatered wax liquid can be directly used.

Description

technical field [0001] The invention relates to the field of investment casting, in particular to a high-frequency induction dewaxing and wax-water separation dewaxing kettle. Background technique [0002] In the process of investment casting (also known as investment casting), melting and losing the casting (dewaxing) is one of the main processes. There are many ways of dewaxing, including hot water dewaxing, high pressure steam dewaxing, organic solvent, flash dewaxing, microwave dewaxing, hot sand dewaxing, etc. The most widely used method is high pressure dewaxing. Steam dewaxing kettle. However, in the current common high-pressure steam dewaxing kettles, the steam is mostly generated by using heating pipes to heat water to generate steam. After the steam valve is opened, it enters the sealed dewaxing box and the pressure of the steam continuously entering the box also increases. The wax material in the wax melts and flows out in the high-pressure steam to achieve the ...
