Energy-saving syphon type degreasing device

Abstract

The invention discloses an energy-saving syphon type degreasing device which belongs to the field of degreasing devices for powder metallurgy injection forming parts. The device comprises a furnace pipe platform, a furnace pipe, a furnace body, a catcher, a vacuum pumping mechanism and a protective gas leading pipe, wherein the center of one side of the furnace pipe platform is provided with a base; longitudinal through holes are arranged in the base; the side surface of the base is provided with horizontal through holes; a group of locking buttons are arranged at the edge part of the furnacepipe platform in the circumference direction; the furnace pipe is arranged on the furnace pipe platform; the furnace body is sheathed outside the furnace pipe; the surface of a heat preservation fire-proof layer of the furnace body is provided with a group of electric heating rods in a laying way; a furnace cover is equipped on the top of the furnace body; the catcher is fixed in the center of one side of the furnace pipe platform; the vacuum pumping mechanism is arranged at one side of the furnace body; one end of the protective gas leading pipe extends into the interior of the furnace pipe;the other end of the protective gas leading pipe is connected with a protective gas resource device; and the electric heating rods and the vacuum pumping mechanism are connected with an electrical control device in an electrical control way. The device has the advantages of increasing the degreasing speed, being beneficial to material feeding and discharging, saving energy, and being capable of enabling the furnace pipe and the furnace body to be combined or separated conveniently.

Description

Technical field [0001] The present invention belongs to the technology field of powder metallurgy injection molding components, which involves a energy -saving siphon -type abandoned device. Background technique [0002] Metal Injection Molding (MIM) is a multidisciplinary technology that integrates plastic molding technology, polymer chemistry, powder metallurgy technology and metal materials.Complex -shaped products can make high -density, high -precision and three -dimensional complex shapes through sintering.The technology was the first to be invented by Parmatech in the United States in the last century (1973), and was widely used in Europe and the United States and Japan in the early 1980s.This technique has the strengths of less process steps, no need to cut or a small amount of cutting and high economic benefits, and can overcome the traditional powder metallurgical process products with low density, uneven material, poor mechanical and physical properties, difficulty for...

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 inconvenient to clean, because during use, especially in the process of loading the blank into the furnace, there will inevitably be damage to the blank, and if it cannot be cleaned in time, it will affect subsequent use; Fourth, The furnace body has no heat preservation measures, which easily leads to energy waste; fifth, when the furnace body and the furnace are of a split structure, although it is convenient to maintain the furnace body, such as replacing the heating elements on the furnace body, if there is a lack of If it is a reasonable measure to lock or unlock the furnace body and the furnace body reliably and conveniently, it will be counterproductive. Perhaps for this reason, the integrated structure of the furnace body recommended by CN2595500Y
