Problems solved by technology

[0003] The original granulation process has the following disadvantages in use: 1. The binders used for granulation are acetone and cellulose acetate. Acetone is poisonous and flammable, which is harmful to the human body and has potential safety hazards; 2. The granulation process It is artificial rubbing, the production volume is limited, the efficiency is low, and the labor intensity of the workers is high; 3. The original granulated powder has poor fluidity, poor consistency of the material, and short shelf life

Embodiment 1

[0008] Example 1: First, mix 5 parts of polyethylene glycol with 68 parts of pure water at 100°C to dissolve the polyethylene glycol to make a binder solution; take 100 parts of glass powder with an average particle size of 5.5 μm , Pour the prepared binder solution into a high-speed stirring device at 1300 rpm, add weighed glass powder while stirring, and continue stirring until the binder and glass powder are evenly mixed; Add a colloid mill between the high-speed mixing equipment and the low-speed mixing equipment to grind the material so that the average particle size of the material is 3.5 μm; send the uniformly mixed binder and glass powder slurry into the 80 rpm low-speed mixing equipment After the slurry after low-speed stirring is filtered through a 50-mesh sieve, it is fed into the pipeline by a slurry pump with a pressure of 2Mpa and the slurry is pressed into the nozzle. The spraying speed is used to spray the material. When the spraying starts, the inlet temperatu...

Embodiment 2

[0009] Example 2: First, mix 5.3 parts of polyethylene glycol with 65 parts of pure water at 70°C to dissolve the polyethylene glycol to make a binder solution; take 100 parts of glass powder with an average particle size of 4.5 μm 1. Pour the prepared binder solution into a high-speed stirring device at 1200 rpm, and add weighed glass powder while stirring. After the addition is completed, continue stirring until the binder and glass powder are evenly mixed; Send the uniformly mixed binder and glass powder slurry into a low-speed stirring device at 100 rpm; the slurry after low-speed stirring is filtered through a 30-mesh screen, and then input by a slurry pump with a pressure of 2.6Mpa Pipeline and press the slurry into the nozzle, and spray the material at a spray speed of 80 kg / h in the drying tower with a negative pressure of 200pa. When starting to spray, control the inlet temperature of the drying tower to 430°C and the outlet temperature to 200 °C; after the start of s...

Embodiment 3

[0010] Example 3: First, mix 5.5 parts of polyethylene glycol with 70 parts of pure water at 80°C to dissolve the polyethylene glycol to make a binder solution; take 100 parts of glass powder with an average particle size of 5.0 μm Pour the prepared binder solution into a high-speed stirring device at 1500 rpm, and add weighed glass powder while stirring. After the addition is completed, continue stirring until the binder and glass powder are evenly mixed; Send the uniformly mixed binder and glass powder slurry into a low-speed stirring device at 120 rpm; the slurry after low-speed stirring is filtered through a 40-mesh screen, and then input by a slurry pump with a pressure of 2.2Mpa Pipeline and press the slurry into the nozzle, and spray the material at a spraying speed of 70 kg / h in the drying tower with a negative pressure of 120pa. When starting to spray, control the inlet temperature of the drying tower to 410°C and the outlet temperature to 195 °C; after spraying, the ...

Abstract

This is a craft of producing grain, first mix the ether and the pure water, make the knotting dose; put the knotting dose solution into the equipment of high speed mixing, adding the glaze powder while mixing, adding over, go on mixing to even; put the even knotting dose and the glaze powder liquid into the mixing equipment of low speed; after filtered, draw them in the dry tower of 50pa--300pa, then put them in the vibration sieve of 50Hz, up hole 60mu, down hole 150mu, gather the qualified grain powder between the two layer. The invention decreases the cost and the labor; increase the quality and the producing efficiency.

Description

technical field [0001] The invention relates to a support glass rod granulation process. Background technique [0002] Granulation is a process in the production process of bracket glass rods. It is the process of adding binders to glass raw powder to make the glass powder into a granular powder that is easy to shape. The original granulation process is as follows: the binder used for granulation is acetone and cellulose acetate; the granulation equipment mainly includes a crushing machine and a vibrating screen; the specific process of granulation is as follows: (1) Weigh 3kg of cellulose acetate Take 18 liters of acetone, pour cellulose acetate into the acetone and stir until cellulose acetate dissolves completely and become the prepared binder; (2) weigh 8kg glass powder and 1.5kg binder, Pour the glass powder into the crushing machine, start the crushing machine, and add the weighed binder during the operation of the equipment. The crushing machine runs for 5 minutes a...
