Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a method for making a special prestressed extrusion screw for solid waste granulation is characterized by:

[0022] Step 1: Select 40Cr or 38 CrMoAl or 42CrMo forgings to make mandrel Ⅰ2 and mandrel Ⅱ5, connect mandrel Ⅰ2 and mandrel Ⅱ5 after rough turning and tempering, and finish car mandrel Ⅰ2 based on the bearing position of mandrel Ⅱ5 to ensure two The concentricity of the

[0023] Step 2: Precision investment casting of the spiral reamer half ring 7, the material is preferably ZG270-500, the casting is quenched and tempered after annealing, the hardness is HRC25-32, and the two spiral reamer half rings 7 are locked by high-strength bolt assembly 6 after drilling .

[0024] Step 3, the spiral reamer ring assembly 4 is threaded into the mandrel I2 in sequen...

Abstract

The invention relates to the technical field of solid waste treatment, in particular to a manufacturing method of a special prestressed extrusion screw for solid waste granulation. The manufacturing method is characterized by comprising manufacturing methods of a tip cone nut, a tip cone nut sleeve seat, a mandrel I, a mandrel II, a spiral reamer ring assembly and a key. Prestress is applied to the spiral reamer ring assembly by the tip cone nut, and during working, the mandrels are not stressed or bear lower stress due to two-phase equilibrium when stress is transmitted to the mandrels through the tip cone nut, so that the service life of each mandrel can be long.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a method for manufacturing a special prestressed extrusion screw for granulation of solid waste. Background technique [0002] The solid waste part of industrial discharge has available residual calorific value and can be made into renewable fuel. At the same time, the purpose of reducing pollutant emissions is achieved through pyrolysis. However, the source of solid waste is scattered and its physical characteristics are extremely uncertain. , such as softness, hardness, elasticity, fluidity, etc., if it is to be prepared as a renewable fuel, in addition to a certain fuel heat load, the weight and size of the recycled fuel particles must be uniform, and its bulk density must reach a certain index. Therefore, the method of extrusion granulation should be a better technical solution, but the extrusion screw is easily damaged by solid waste and scrapped in its entiret...
