Embodiment 1

[0041] Example 1 for the concrete matrix is ​​as follows:

[0042] 20 parts of coarse aggregate, 20 parts of light aggregate, 10 parts of fly ash, 0.1 part of polypropylene fiber, 0.15 part of water reducing agent, 0.2 part of calcium formate, and the rest is fast hardening cement.

Embodiment 2

[0044] 30 parts of fast hardening cement, 20 parts of coarse aggregate, 20 parts of light aggregate, 0.1 part of polypropylene fiber, 0.13 part of water reducing agent, 0.2 part of calcium formate, and the rest is fly ash.

Embodiment 3

[0046] 50 parts of fast hardening cement, 10 parts of coarse aggregate, 10 parts of light aggregate, 0.1 part of polypropylene fiber, 0.13 part of water reducing agent, 0.2 part of calcium formate, and the rest is fly ash.

[0047] The raw materials of the concrete matrix (1) are transported to the microcomputer batching system by the reamer and bucket lifter, are weighed by the batching system and then fed to the rapid mixer, mixed with the measured water and other additives to form a semi-dry ash, and poured into One-time molding is performed in a cavity with a vacuum insulation board. After 15-30 seconds of vibration and extrusion, the mold is released. The mold is divided into upper and lower molds. After the upper mold is lifted, the formed block is ejected from the lower mold to obtain a size of 390×240×190 mm or 390×190×190 mm vacuum insulation board composite insulation block.

[0048] As a preferred embodiment, the polypropylene fiber can be replaced with the following fib...

Abstract

The invention discloses a solar water heater, which comprises a water tank for storing heated hot water, wherein the water tank is of a cubic structure, and a heat-preservation layer is arranged on the outside of the cubic structure; the heat-preservation layer is a heat-preservation building block; the heat-preservation building block is formed by seamlessly and closely combining a concrete substrate (1) and a vacuum insulation panel (2); the vacuum insulation panel (2) divides the concrete substrate (1) into two parts, and the two parts are closely adhered to form a sandwich structure; a mortise (3) and a glossal groove (4) are arranged on the left and right sides of the heat-preservation building block. The solar water heater is provided with the heat-preservation building block, so that the loss of heat is effectively prevented, and energy resources are saved.

Description

Technical field [0001] The invention belongs to the field of solar energy, and in particular relates to a solar water heater with a thermal insulation structure, belonging to the field of F24J. Background technique [0002] Solar energy is an inexhaustible clean energy, and the resources are huge. Countries all over the world have regarded the use of solar energy as an important item in the development of new energy. The Chinese government has also clearly stated in the "Government Work Report" Actively develop new energy. [0003] The vacuum insulation panel (Chinese patent CN102720922B) is based on the principle of vacuum insulation, which reduces convection and radiation heat exchange by maximizing the vacuum degree in the panel and filling it with core insulation material. The thermal conductivity can reach 0.003W / (m·K)~0.008W / (m·K), the performance is far better than ordinary insulation materials, and the thickness of the insulation layer can be greatly reduced, thereby great...
