Embodiment 1

[0030] Such as figure 1 , figure 2 The base of a cylindrical thermal insulation riser shown is in the shape of a tapered sleeve with an inner conical surface 33 as a whole, the upper opening 32 of the inner conical surface 33 matches the bottom of the cylindrical thermal insulation riser, and the lower opening 32 of the inner conical surface 33 The radius of the opening 31 is less than the radius of the upper opening 32; the cone angle of the inner conical surface 33 is 90°, and the radius of the upper opening 32 of the inner conical surface 33 is twice the radius of the lower opening 31; it is an equal wall thickness structure.

[0031] The base is made as follows:

[0032] 30 kg of paper slag from waste paper, 40 kg of slag cotton, 40 kg of cornstarch, and coarse quartz powder or quartz stone with a fineness of 600-900 mesh are produced by water method and screened through a 600-mesh screen. 600-700 kg of quartz waste powder, according to the above proportions. Add appro...

Abstract

The invention discloses a cylindrical insulating riser base, wherein, the integral body is a taper sleeve shape with inner taper cone surface, the upper shed of the inner taper cone surface is matched with the bottom of the cylindrical insulating riser, and the radius of the lower shed of the inner taper cone surface is smaller than the radius of the upper shed. The cylindrical insulating riser base includes components as follows: 84%-87% of quartz powder, 3.5%-4.5% of paper slag, 4.5%-6% of slag wool, and 4.5%-6% of starch. The technical program has heat insulation effect, and can greatly improve the process production rate.
