Abstract

The utility model discloses a spherical insulation dead head, which comprises a dead head body, a dead head inlet and a dead head cavity body, wherein the dead head inlet is a circular inlet; and the dead head cavity body is a spherical cavity body. According to the utility model, the dead head cavity body is the spherical cavity body; simultaneously, the dead head inlet is the circular inlet; therefore, the spherical insulation dead head is capable of effectively preserving the heat of the feed liquid entering the dead head cavity body; as a certain amount of heat can be released when a heating insulation material is contacted with the feed liquid, the temperature decreasing gradient can be retarded; the spherical insulation dead head is beneficial to preventing brick materials from being shrunk or non-compacted; and the use rate of the feed liquid is increased.

Description

A kind of spherical heatproof riser

Technical field

The utility model relates to a kind of rising head, relates in particular to a kind of spherical heatproof riser.

Background technology

At present; The rising head that uses in Corhart Zac-block manufacturing enterprise all is square rising head, and as depicted in figs. 1 and 2, described square rising head comprises rising head body 1; The rising head import 3 that rising head body 1 top is provided with is square, and rising head body 1 inner rising head cavity 2 cross sections are square.During use square rising head is placed brick material foundry goods top, can be brick material foundry goods feeding liquid material is provided.Because square rising head import 3 is bigger, the heat insulation effect of rising head cavity 2 is relatively poor, and the cooling gradient in the rising head cavity 2 is bigger, can cause shrinkage cavity of brick material and liquid material utilization rate low, influences the quality of brick material foundry goods.

The utility model content

The purpose of the utility model provides a kind of spherical heatproof riser, can strengthen the heat insulation effect of rising head cavity, avoids brick material shrinkage cavity or not fine and close, improves liquid material utilization rate.

The utility model adopts following technical proposals:

A kind of spherical heatproof riser comprises rising head body, rising head import and rising head cavity, and described rising head import is circular import, and the rising head cavity is a spherical cavity.

The diameter of said rising head import is less than the circular cross-section diameter of rising head cavity.

Said rising head inside cavity is provided with heat-insulation layer.

The utility model is set to spherical cavity through the rising head cavity; Circular import is adopted in rising head import simultaneously; Can play insulation effect to the feed liquid that gets into the rising head cavity effectively, can discharge certain heat when contacting with feed liquid, can slow down the cooling gradient owing to the heat preservation material; Help avoiding brick material shrinkage cavity or not fine and close, improve liquid material utilization rate.

The specific embodiment

Like Fig. 3 and shown in Figure 4, the utility model comprises rising head body 1, and the rising head import 3 that rising head body 1 top is provided with is circular import, and rising head body 1 inner rising head cavity 2 is a spherical cavity, and the diameter of rising head import 3 is less than the circular cross-section diameter of rising head cavity 2.Said rising head cavity 2 set inside have heat-insulation layer, and heat-insulation layer can adopt thermal insulation coatings.In the utility model; Because circular rising head import 3 is less, and the volume of rising head cavity 2 is bigger, the insulation effect that can play the feed liquid that gets into rising head cavity 2 effectively; Because rising head cavity 2 inside also are provided with heat-insulation layer; Can further improve the insulation effect of rising head cavity 2, can slow down the cooling gradient effectively, help avoiding brick material shrinkage cavity or not fine and close.Simultaneously,, bigger static pressure is provided, provides feed liquid to carry out feeding for brick material foundry goods effectively thereby can hold more feed liquid because the volume of rising head cavity 2 is bigger.
