Problems solved by technology

[0021] The outer wall thickness of the vacuum-extruded flat ceramic solar panels and trough ceramic solar panels manufactured before is determined by the mold. The test shows that the outer wall thickness of the ceramic solar panel is especially the thickness of the sunlight absorbing surface (sun-facing surface) of the ceramic solar panel. The thinner the wall thickness, the higher the efficiency of the ceramic solar panel collector. The ceramic solar panel made of ordinary ceramic mud by vacuum extrusion mo

Embodiment

[0054] 1. The mud material is made of ordinary ceramic raw materials through conventional ceramic raw material processing methods, and is extruded into a flat ceramic solar panel green body by using a flat porous mold with a vacuum extruder extrusion method, such as figure 1 As shown, the dimensions after drying: length 1300 mm, width 670 mm, total thickness 28 mm, upper and lower wall thicknesses 3.2 mm, surface unevenness 3 mm, after being processed by the ceramic solar panel wall thickness reduction device, the ceramic solar panel Thin the wall thickness of the upper surface of the biscuit (the sunny side) to 1.6 mm to extract 55% of the vanadium tailings and 45% of the ordinary ceramic raw material, and jointly ball mill it into a slurry sprayed on the surface of the biscuit of the ceramic plate solar panel, after drying, firing Become flat type black porcelain composite ceramic solar panel, the wall thickness of ceramic solar panel upper surface (sunny side) is 1.4 millime...

Abstract

The thickness of the outer wall of the prior ceramic solar panel formed by vacuum extrusion is determined by a mold, the thinner the ceramic solar panel the more difficult forming and the lower forming rate of the ceramic solar panel, even the ceramic solar panel can not be formed, the test proves that the thinner the sun suction surface (going-to-the-sun surface) of the ceramic solar panel, the higher efficiency of the ceramic solar panel heat collector. The invention grinds or mills the going-to-the-sun surface of the ceramic solar panel biscuit by hands and a portable grinder and special equipment, and decreases the thickness of the going-to-the-sun surface, thereby leading the ceramic solar panel to have higher production yield and have higher solar energy absorption rate.

Description

(1) Technical field [0001] The invention relates to the technical field of ceramic manufacturing and application of ceramic products, in particular to ceramic solar heat collectors-ceramic solar panels, and more specifically to methods and equipment for reducing the wall thickness of the ceramic solar panel's sunny side. (2) Background technology [0002] Solar energy is the fundamental source of conventional fossil energy such as coal, oil, and natural gas, as well as wind energy, water energy, ocean energy, and biomass energy. The solar energy radiated to the earth's land surface is tens of thousands of times the total energy consumed by humans in the same period in the world, and is the total amount of wind energy in the world. 10,000 times the volume, 100,000 times the energy of water. [0003] The advantages of solar energy are universal, huge, and harmless, and the disadvantages are scattered, random, and intermittent. The research on solar energy utilization is mainly...
