Detailed Description
The invention will be further described with reference to specific examples:
referring to fig. 1 to 4, the present embodiment provides a manufacturing process of an environment-friendly heat insulation kiln, including the following steps:
s1, building, namely building the ring-shaped brick tube 10 which is vertically arranged on a horizontal table top by using refractory bricks, wherein the refractory bricks are refractory bricks used in a conventional kiln, the horizontal table top is preferably a table top which is not easy to bond slurry, of course, if necessary, a wood board can be placed on the horizontal table top as a template, and the ring-shaped brick tube 10 is built on the wood board to avoid the subsequent slurry which is poured from bonding on the horizontal table top.
Preferably, in the present embodiment, the ring-shaped brick tube 10 is a ring-shaped tube.
S2, sleeving a pipe, and manufacturing a steel pipe 20 with the cross section shape being the same as that of the annular brick pipe 10, wherein the length of the steel pipe 20 is the same as that of the annular brick pipe 10 or slightly larger than that of the annular brick pipe 10, and the inner diameter of the steel pipe 20 is larger than the outer diameter of the annular brick pipe 10. The steel sleeve 20 is sleeved outside the annular brick tube 10, so that the steel sleeve and the annular brick tube are coaxially arranged, and an annular cavity is formed between the inner side wall of the sleeved steel tube 20 and the outer side wall of the annular brick tube 10.
Preferably, the two ends of the steel pipe 20 are respectively welded with a connecting plate 21, the connecting plate 21 is provided with a through hole 26, the connecting plate 21 is preferably an annular plate, the through hole 26 on each connecting plate 21 is provided with a plurality of through holes, and the through holes 26 are uniformly distributed by taking the axis of the connecting plate 21 as the center. In addition, in the present embodiment, of the two connecting plates 21 connected to the same steel pipe 20, one connecting plate 21 is provided with a positioning protrusion 22, the other connecting plate 21 is provided with a positioning groove 23 matched with the positioning protrusion 22, the positioning protrusion 22 and the positioning groove 23 are both arranged coaxially with the corresponding through hole 26, and there are a plurality of positioning protrusions 22 and positioning grooves 23 respectively.
And S3, pouring refractory and heat-insulating slurry into the annular chamber, wherein the refractory and heat-insulating slurry is slurry widely used in conventional refractory kilns and is not described in detail herein. And forming a pouring layer 30 filling the annular cavity after the refractory heat-insulating slurry is solidified, wherein the annular brick tube 10, the steel tube 20 and the pouring layer 30 together form a kiln body, and certainly, the kiln body needs to be cured after the pouring is finished, the specific curing mode is the same as that of a conventional kiln, and is not described in detail here, and in addition, if a wood board is placed in the step S1, the wood board needs to be detached after the curing.
It should be noted that the three steps S1-S3 can be prefabricated in a factory, or even mass-produced, and then the following steps S4 are performed when the product is transported to an installation site.
