Description

A kind of dewaxing furnace is with the dewaxing retracting device

Technical field

The utility model relates to a kind of dewaxing retracting device, and the dewaxing furnace that particularly relates to a kind of metal or metal injection molding product is with the dewaxing retracting device.

Background technology

At present, general industry is made up of body of heater, flue insulation, heater element, material platform, vacuum system, dewaxing system, air-channel system, electric control system, pressure and temperature measuring equipment, water system etc. with dewaxing furnace.Wherein dewaxing system is the core part of dewaxing furnace, the capture that whether rationally directly has influence on the wax that at high temperature volatilizes in the product of this system authority, reclaims and slough what of wax in the product, and then has influence on the quality of product.The way that the dewaxing system of at present general dewaxing furnace adopts growth dewaxing pipeline and employing to intercept reclaims and captures wax steam; The material that adopts is a metal pipe material, this dewaxing pipeline mainly exist catch wax incomplete, catch the wax that the ceratuba road blocked and cleared up capture easily and be difficult to problems such as cleaning.Gently then influence the stove function, cause product rejection when serious.

The utility model content

It is effective that the utility model technical problem to be solved provides a kind of wax of catching, and pipeline cleaning simply reaches dewaxing furnace simple in structure with the dewaxing retracting device.

In order to solve the problems of the technologies described above; The dewaxing furnace that the utility model provides is with the dewaxing retracting device, and horizontal collection fat jar is provided with import and outlet, and described horizontal collection fat jar is provided with chuck; The outlet of described horizontal collection fat jar is to being connected to condenser; Described condenser is to being connected to perpendicular trap, and the outer wall of described perpendicular trap is provided with the water-cooled interlayer, and described perpendicular trap inside is equipped with the Pall ring that condensing trapping is used.

Described condenser is a coiled tube condenser.

The dewaxing furnace that adopts technique scheme is with the dewaxing retracting device; Horizontal collection fat jar adopts the cylinder double layer jacket structure; In chuck, be connected with the cooling medium such as the liquid such as water, liquid nitrogen of circulation usefulness, make vapours when contacting, take away wax steam to the wax steam heat and become liquid or solid and capture with horizontal collection fat jar barrel; Condenser adopts the coiled tube condenser of coil arrangement; Also be connected with the cooling medium of circulation in the coil pipe of coiled tube condenser; Coiled tube condenser has increased the contact area of wax steam and coiled tube condenser; A large amount of temperature that capture wax steam and reduced the wax steam that does not capture provide condition for perpendicular trap fully captures wax steam; Perpendicular trap inside is placed with Pall ring and the employing water-cooled sandwich that condensing trapping is used; The water-cooled interlayer is connected with circulating cooling medium to be reduced the temperature of Pall ring and wax steam and then captures wax; Pall ring is a loose structure; At wax steam during through the Pall ring of loose structure, the capture that is cooled of wax steam.

The beneficial effect of the utility model is, and is reasonable in design, easy to process, simple in structure, captures effectively, and cleaning is convenient.

In sum, the utility model be a kind of be that to catch wax effective, pipeline cleaning simply reaches dewaxing furnace simple in structure with the dewaxing retracting device.
