Platform for hanging, turning, slip casting of black porcelain composite ceramic solar panel

Abstract

A platform for hanging, turning, slip casting of a black porcelain composite ceramic solar panel consists of a slip casting platform bracket, a rail, a row of plaster moulds and a plaster mould clamping device, wherein pulleys are arranged at two ends of a plaster mould central shaft and can roll on the rail, the plaster moulds are hung on the rail through the pulleys on the central shaft, and can move along the rail, and the plaster moulds are rotated or turned around the central shaft under the condition of no change of height of gravity of center so as to realize demoulding. For the platform, a trolley and a crane on the original plaster mould slip casting platform of the black porcelain composite ceramic solar panel are omitted, the center of gravity of the plaster moulds are in the same horizontal plane all the time during the working process without vertical moving, the equipment is simplified, the occupied area and space of the equipment can be reduced, the operation procedures are decreased, and the forming efficiency is greatly improved.

Problems solved by technology

[0003] Solar energy is a surface energy source. Both theory and practice have proved that the most efficient solar collector is a through-hole flat box solar collector made of metal materials. In this collector, the sun-absorbing surface is covered with heat to be heated Medium, heat exchange is the most direct and rapid, and the heat conduction distance is the shortest. However, the metal material that can withstand hot water corrosion for a long time is copper. This structure requires a large amount of copper. Copper is very expensive, the weld is very long, and the manufacturing process is complicated. , the manufacturing cost is very high, it is difficult to mass-produce and use

[0004] The main disadvantages of vacuum glass tubes are: the vacuum glass tube is composed of coaxial inner and outer glass tubes, one end is closed, the inner and outer tubes are vacuumed, the outer tube is transparent, and the outer surface of the inner tube is covered with solar absorbing paint

Because the vacuum layer, sealing ring, dustproof ring, and rear stock must be used, the black sunlight absorbing surface only accounts for about 60% of the lighting projection area. When the sun shines directly at noon, part of the sunlight passes through the gap between the black surfaces and is not used. , the heat collection efficiency is reduced at noon when the sun is strongest; the vacuum degree keeps decreasing during use, reducing the heat preservation effect; a closed blind pipe structure is easy to precipitate water alkali and impurities in water, reducing the heat exchange area; solar energy absorbs sunlight from the paint The absorption rate is easy to attenuate, which is a common shortcoming of solar energy absorption coatings for solar water heaters; the glass tube is made of borosilicate glass, and the melting temperature is 1650°C, which requires high energy consumption and high price of boron oxide; these shortcomings lead to the manufacturing cost and consumption of vacuum glass tubes Energy is relatively high, life is relatively short, the general effective life of 8-10 years

[0005] The main disadvantages of the copper tube plate solar collector are: the sunlight absorption rate of the solar absorbing coating is easy to attenuate; the copper material is very expensive and requires electrolytic purification, and the manufacturing cost and energy consumption are high; the heat collecting copper tube has a large horizontal interval and a long heat conduction distance , affect the efficiency; the weld is easy to corrode; the general effective service life is 8-20 years

[0013] The above-mentioned black porcelain composite ceramic solar panel gypsum mold grouting molding platform equipment structure is relatively complicated, and the operation process It is more complicated, there are many operating procedures, each operation procedure takes a long time, the production efficiency is relatively low, and the equipment cost is high. Installing a crane above the platform increases the floor area and space of the equipment
