[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0033] See also Figure 1-8 A pure oxygen reformer lining casting mold includes a furnace body 1, the inner cavity of the furnace body 1 is provided with a plurality of coaxial mounting rings, and the mounting rings are spliced ​​by a plurality of parts. The mounting ring can be spliced ​​by two spliced ​​half rings 2, or by a plurality of annular parts, and the diameter of the mounting ring can be adapted according to the diameter of the furnace body 1. The two spliced ​​half rings 2 are plugged together by the plug rod and the slot at the end, and the bolts are inserted into the slot and threadedly connected with the plug rod. Each mounting ring is fixedly connected with a plurality of connecting seats 10, and two adjacent coaxial connecting seats 10 are commonly plugged with a vertical connecting rod 9, and the number of connecting seats 10 fixedly connected by a single mounting ring is at least three. When there are less than three connecting rods 9 between two mounting rings, the support is unstable. The connecting rod 9 can be of fixed length or telescopic adjustment type, and the length of the connecting rod 9 is determined by the interlayer spacing of the template. Each mounting ring is equipped with several bite components 3, each bite component 3 is fixedly connected to two adjustment plates 4, and the two adjustment plates 4 are connected by two crossed telescopic components 5, the end of the telescopic component 5 is rotatably connected to the end of the adjustment plate 4, each adjustment plate 4 away from the mounting ring is fixedly connected to a socket 6, each socket 6 is plugged with a template, and several templates are spliced ​​together to form a casting cavity between the furnace body 1 and the spliced ​​templates. The middle protrusion of the side of the template is inserted into the socket 6, and the fixing bolt is passed through the socket 6 and threadedly connected to the middle protrusion of the side of the template. The inner side wall of the furnace body 1 is fixedly connected with several evenly distributed Y-shaped bite reinforcement ribs 11. A mesh structure cross-linked with the Y-shaped bite reinforcement ribs 11 can be added between the Y-shaped bite reinforcement ribs 11 to improve the strength of the casting layer. The mesh structure can be composed of ceramic fibers. The position and posture of the socket 6 can be adjusted by adjusting the length of the telescopic component 5 between the two adjustment plates 4. When the two telescopic components 5 are of the same length, the template remains vertical. When the two telescopic components 5 are extended or shortened by the same distance at the same time, the two adjustment plates 4 connected thereto are moved closer or apart to adjust the position of the socket 6 and the template. When the lengths of the two telescopic components 5 are inconsistent, the template posture is corrected by using the overall splicing of the template.

[0034] Each connection seat 10 is provided with two coaxial locking rings, and each locking ring is an open ring, a locking bolt is provided at the opening of the locking ring, and a fixing plate is provided between the two locking rings of the same connection seat 10. After the connecting rod 9 is inserted into the locking ring, it abuts against the fixing plate, and then the nut of the locking bolt is tightened, so that the locking ring is slightly deformed to clamp the connecting rod 9.

[0035] Each snap assembly 3 includes: a U-shaped seat 301 that fits with the mounting ring, a clamping plate 302 that is rotatably connected to the top of one side of the U-shaped seat 301, a fixing bolt that penetrates the clamping plate 302, and the fixing bolt is threadedly connected to the top of the other side of the U-shaped seat 301. A single snap assembly 3 can be provided with multiple fixing bolts. Unscrew the fixing bolts, lift up the clamping plate 302, and then remove the snap assembly 3 from the mounting ring.

[0036] Each telescopic assembly 5 includes: a first mounting plate 501 and a second mounting plate 502, both of which are rotatably connected to the end of the adjustment plate 4, and a sliding rod 504 is slidably inserted into the first mounting plate 501, and the sliding rod 504 is fixedly connected to the second mounting plate 502.

[0037] The template set at the bottom layer of the splicing template is the bottom template 7. The bottom of each bottom template 7 extends toward the furnace body 1, and the bottom of the bottom template 7 is pressed against the inner wall of the furnace body 1. The template set in the middle and upper part of the splicing template is the middle and upper template 8. A plug-in slot is set at the top of the bottom template 7, a plug connector adapted to the plug-in slot is set at the bottom of the middle and upper template 8, and a plug-in slot is set at the top of the middle and upper template 8. Each bottom template 7 and middle and upper template 8 has a T-shaped protrusion extending on one side and a T-shaped slot adapted to the T-shaped protrusion on the other side, except for the middle and upper template 8 set at the top layer of the splicing template. The middle and upper template 8 at the top layer lacks space for longitudinally plugging the T-shaped protrusion, and the pressure of the mixed casting material on the splicing template is relatively small, so there is no need to set a T-shaped slot and T-shaped protrusion. The top of the splicing template does not contact the top wall of the inner cavity of the furnace body 1, and a distance is reserved for pouring the pouring cavity. Both the bottom template 7 and the middle upper template 8 can enter the inner cavity of the furnace body 1 from the opening of the furnace body 1. The top and bottom of the inner cavity of the furnace body 1 need to be subjected to additional refractory treatment.

[0038] Working principle:

[0039] During construction, a layer of bottom template 7 is first assembled at the bottom of the furnace body 1, and then an installation ring is assembled. Then, the engaging components 3, the adjusting plate 4, the telescopic components 5 and the plug-in seat 6 corresponding to the number and position of the bottom template 7 are installed on the installation ring. By adjusting the length of the telescopic component 5, the middle protrusion of the side of the bottom template 7 is inserted into the plug-in seat 6, and the fixing bolt is passed through the plug-in seat 6 and threadedly connected with the middle protrusion of the side of the bottom template 7. Then, the connecting seat 10 on the installation ring is upwardly inserted and fixed with the connecting rod 9, and another installation is installed on the top of the installed connecting rod 9. Install the ring, and at the same time, splice a layer of middle and upper template 8 on the top of the bottom bottom template 7, and use the bite assembly 3, adjustment plate 4, telescopic assembly 5 and socket 6 corresponding to the number and position of the middle and upper template 8 to connect the installation ring with the middle and upper template 8, so as to extend the splicing template upward until a casting distance is reserved with the top wall of the inner cavity of the furnace body 1, and no T-shaped slots and T-shaped protrusions are set between the top middle and upper templates 8, and finally pour the stirred furnace lining casting material into the casting cavity between the furnace body 1 and the splicing template. After the furnace lining solidifies, the casting mold is removed in the same way as the installation;

[0040] When the furnace body 1 is relatively high, a mold of a certain height may be built first for pouring, and after the poured furnace lining solidifies, a mold may be built upwards for pouring, and so on until it approaches the top wall of the inner cavity of the furnace body 1 .

[0041] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
