Siphon degreasing plant

Abstract

A siphon degreasing plant belongs to the field of powder metallurgy injection molding component degreasing plants and comprises a furnace pipe platform with a group of elevated legs, a furnace pipe, a furnace, a catcher, a vacuumizing mechanism and a shielding gas inlet pipe. A base is arranged at the center of one upward side of the furnace pipe platform in use, a longitudinal through hole is arranged on the base, and a group of transverse through holes is arranged on the lateral face of the base along the circumferential direction of the base. The furnace pipe is arranged on the furnace pipe platform. The furnace is sleeved outside the furnace pipe, and a group of electric heating rods are spread on the inner wall of the furnace. The catcher is fixed to the center of one side of the furnace pipe platform facing the elevated legs. The vacuumizing mechanism is arranged on one side of the furnace body. One end of the shielding gas inlet pipe extends into a furnace pipe cavity after passing through the furnace pipe platform, the other end of the shielding gas inlet pipe is connected with a shielding gas source device, a jacket is formed on the furnace, a cooling medium inlet joint is arranged on the lower portion of the jacket, and a cooling medium outlet joint is arranged on the upper portion of the jacket. The siphon degreasing plant has the advantages that degreasing speed can be increased, charging and discharging are benefited, and the furnace pipe platform can be conveniently cleaned.

Description

technical field [0001] The invention belongs to the technical field of degreasing devices for powder metallurgy injection molding parts, and in particular relates to a siphon type degreasing device. Background technique [0002] Metal injection molding technology (Metal Injection Molding, referred to as MIM) is a technology that integrates plastic molding technology, polymer chemistry, powder metallurgy technology, and metal materials. Products with complex shapes can be sintered to manufacture structural parts with high density, high precision and three-dimensional complex shapes. This technology was first invented in the last century (1973) by Parmatech Corporation of California, USA, and was widely used in Europe, America and Japan in the early 1980s. This technology has the advantages of fewer process steps, no cutting or a small amount of cutting and high economic benefits, and can overcome the traditional powder metallurgy process of low density, uneven material, poor...

Problems solved by technology

[0006]A typical example is the "vacuum degreasing and sintering integrated furnace" disclosed by the utility model patent authorization announcement number CN2595500Y. The technical effects mentioned in the 7th to 9th lines on page 2, but there are the following deficiencies: First, the degreasing speed is slow, because only the exhaust pipe protruding into the furnace body from the bottom of the furnace body (the patent is called the furnace body exhaust channel) It is difficult to lead the adhesive gas volatilized from the blank in the furnace out of the furnace under negative pressure; second, it is inconvenient to load the blank into the furnace and take out the finished product, and the patent does not provide technical inspiration for loading the blank into the furnace; Third, the structure of the furnace body is unreasonable and it is not easy to clean, because during use, especially during the process of loading the blank into the furnace, there will inevitably be damage to the blank. If it cannot be cleaned in time, it will affect subsequent use
