Abstract
The utility model discloses a jetting coal pipe casting mould which is constructed through a segmented circular steel mould through flange connection; the circular steel mould is composed of two semi-circular steel moulds which are connected together through a hinge arranged on one side of the semi-circular steel moulds, and the other side of the semi-circular steel moulds is provided with a bolt used for fastening the semi-circular steel moulds; vibrators are fixedly arranged on the outer wall of the circular steel mould, and the vibrators are in staggered arrangement on both sides of the casting mould, a circular ring is fixedly arranged on the bottom of the segment of the lowest end of the circular steel mould and under the casting mould, and the inner diameter of the circular ring is equal to the diameter of the metal core body of jetting coal pipe. The jetting coal pipe casting mould not only has simple fabrication and convenient construction, but also improves the compactness of refractory casting material and prolongs the service cycle of jetting coal pipe.
Description
Technical field
The utility model relates to a kind of coal powder injection pipe casting mold.
Background technology
At present, the coal powder injection pipe mainly is made up of metallic core, castable refractory and anchor studs three parts, castable refractory is bonded on the metallic core by anchor studs, the quality of castable refractory construction directly influences the life cycle of coal powder injection pipe, but, because coal injection pipe structure is comparatively complicated, be cylindrical structural, and the space between casting mold and the coal powder injection pipe is very little, be unfavorable for cast and vibration, so general casting mold is difficult to guarantee the compactness of castable refractory, damage easily when causing the coal powder injection pipe to use, reduced the life cycle of coal powder injection pipe.
The utility model content
The technical problems to be solved in the utility model is: the utility model has overcome the deficiencies in the prior art, a kind of coal powder injection pipe casting mold is provided, and this casting mold is not only made simply, easy construction, and can improve the compactness of castable refractory, prolong the life cycle of coal powder injection pipe.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of coal powder injection pipe casting mold, circular punching block by segmentation combines by the flange connection, circular punching block is formed by connecting by being arranged on semicircle punching block hinge on one side by the circular punching block of two halves, and the another side of semicircle punching block is provided with the latch that is used for the semicircle punching block of fastening.
For guaranteeing vibrating effect, on the outer wall of circular punching block, be set with vibrator, vibrator is interspersed in the both sides of casting mold, for preventing spillage, be set with an annulus in the bottom that is positioned at casting mold one section circular punching block bottom, the internal diameter of this annulus is identical with the diameter of coal powder injection pipe metallic core.
The beneficial effects of the utility model are that the utility model has changed the shortcoming of the difficult vibration of coal powder injection pipe castable refractory, has improved the compactness of castable refractory, the life cycle that has prolonged the coal powder injection pipe.

The specific embodiment
A kind of coal powder injection pipe casting mold shown in Figure 2 as Fig. 1, circular punching block 1 by segmentation combines by flange 3 connections, flange 3 is welded on the two ends of circular punching block 1, circular punching block 1 is formed by connecting by being arranged on semicircle punching block two hinges 6 on one side by the circular punching block of two halves, be convenient to the unlatching of circular punching block 1 and the demoulding after the cast, the another side of semicircle punching block is provided with latch 2, be used for the semicircle punching block of fastening, be welded with an annulus 5 in the bottom that is positioned at casting mold one section circular punching block 1 bottom, these annulus 5 internal diameters are identical with the diameter of coal powder injection pipe metallic core, be connected with metallic core spot welding during use, after adding the encapsulant sealing, guaranteeing does not have the space between mold bottom and coal powder injection pipe metallic core, can prevent the spillage phenomenon, be welded with a vibrator 4 on the centre position of each circular punching block 1 outer wall, vibrator 4 is interspersed in the both sides of casting mold, the vibration of castable refractory when being used to pour into a mould.During cast, carry out the segmentation formwork, vertically integrated poured, pour into a mould the head of coal powder injection pipe at last, owing to be pouring in vertically clamped moulds, castable refractory is easy to flow in casting mold, under the effect of vibrator 4, just can reach the purpose that improves castable refractory compactness, thus the life cycle that has prolonged the coal powder injection pipe.
