[0012] Compared with the prior art, the present invention provides a refractory mud laying device for the furnace of an industrial vertical waste heat steam boiler, and has the following beneficial effects:

[0013] For the refractory mud laying device of the industrial vertical waste heat steam boiler furnace, fireproof mud is injected into the rotating box through the mud adding box. The fireproof mud will enter the two long boxes through the rotating box. After the injection of the fireproof mud is completed, the mud adding box can be closed, and then the moving bar is moved in the direction of approaching each other, so that the two blocking bars can be driven by the moving rod to move in the direction of approaching each other. In this way, the two blocking bars are separated from the two mud discharging grooves respectively, and then the furnace that needs to be laid with fireproof mud can be sleeved on the two long boxes. Then, the rotation drive is started to drive the rotating rod to rotate, so that the two long boxes can rotate, and the mud in the long boxes can be laid in the furnace. At the same time, the fireproof mud is scraped by the two inclined plates and the two soft plates to make the fireproof mud evenly laid on the furnace body.

[0014] For the refractory mud laying device of the industrial vertical waste heat steam boiler furnace, after moving the limit post to the right, the connecting bar can be moved in the square tube, so that the two moving bars can move back and forth, and then the two blocking bars can be moved. After moving the limit post to different notches on the square tube, the blocking bars can be fixed at different positions, which is convenient for users to use.

[0015] For the refractory mud laying device of the industrial vertical waste heat steam boiler furnace, the stability between the two long boxes and the rotating rod can be improved through the four reinforcing rods, and the fixing effect of the long boxes can be improved. The small plate is convenient for users to move the connecting bar. With the hemispherical block, users only need to press the limit post into the chute, and there is no need to insert the finger into the notch. When moving the connecting bar by using the arc surface of the hemispherical block, the limit post can be completely pushed into the chute by extrusion.

[0016] For the refractory mud laying device of the industrial vertical waste heat steam boiler furnace, after removing it by rotating the moving nut b, the corresponding inclined plate can be rotated back and forth, which is convenient for users to adjust the angle of the inclined plate. In this way, the angle of the corresponding soft plate can be adjusted, so that users can adjust the angle of the inclined plate according to the thickness to be laid. The thickness of the laid fireproof mud will also be adjusted accordingly, so that users can conveniently lay the fireproof mud into different thicknesses according to their needs.

[0017] For the refractory mud laying device of the industrial vertical waste heat steam boiler furnace, after removing the nut c, the long strip can be removed, and then the soft plate can be removed, which is convenient for users to replace different soft plates. By replacing soft plates with different toughnesses and different styles, the effect of scraping the fireproof mud during laying can be different, and different styles can be presented on the surface of the fireproof mud during laying.

[0018] The refractory mud laying device for the furnace of the industrial vertical waste heat steam boiler can continuously apply pressure to the pressure bars in the direction away from each other through the extrusion of the pressure spring b. In this way, the refractory mud is injected between the pressure bars and the corresponding mud outlet grooves. When the moving bar drives the blocking bar to move away from the mud outlet groove, the pressure applied by the pressure spring b can drive the pressure bars to slowly move away from each other, so as to cooperate with the centrifugal force to promote the refractory mud to be laid on the furnace body through the mud outlet grooves.

[0019] 7. The refractory mud laying device for the furnace of the industrial vertical waste heat steam boiler can prevent the pressure bars from fitting against the inner walls of the two long boxes that move away from each other through the limit frame. In this way, it can be avoided that there is no gap between the pressure bars and the mud outlet grooves. Therefore, after the connection between the rotating box and the two long boxes is set between the limit frame and the corresponding mud outlet grooves, when injecting the refractory mud, the refractory mud will enter between the pressure bars and the mud outlet grooves. Then, after blocking the mud outlet grooves with the blocking bars, the injected refractory mud will squeeze the pressure bars to move, so that the pressure spring b can contract and store energy, and the refractory mud can be extruded after opening the mud outlet grooves.

Detailed implementation manner

[0029] Please refer to Figures 1-8, the present invention provides a technical solution: an industrial vertical waste heat steam boiler furnace refractory mud laying device, including a rotary drive 1. The right end of the output shaft of the rotary drive 1 is fixedly installed with a rotary rod 3. The right end of the rotary rod 3 is fixedly installed with a rotary box 5. A mud adding box 6 is fixedly connected to the rotary box 5. A long box 8 is fixedly installed on the rotary box 5. The two long boxes 8 are both communicated with the rotary box 5. The mutually remote side walls of the two long boxes 8 are both provided with mud discharge grooves 26. A blocking strip 16 is movably connected in each of the two mud discharge grooves 26. A plurality of moving rods 17 are fixedly installed on the mutually close sides of the two blocking strips 16. Each moving rod 17 respectively movably penetrates the mutually close side walls of the two long boxes 8. Moving strips 14 are attached to the mutually close side walls of the two long boxes 8. The two moving strips 14 are respectively fixedly connected to each moving rod 17. An inclined plate 9 is provided on each of the side walls of the two long boxes 8. A soft plate 7 is provided on each inclined plate 9. Fireproof mud is injected into the rotary box 5 through the mud adding box 6. The fireproof mud will enter the two long boxes 8 through the rotary box 5. After the fireproof mud injection is completed, the mud adding box 6 can be closed. Then, move the moving strip 14 in the mutually close direction, so that the two blocking strips 16 can be driven by the moving rods 17 to move in the mutually close direction. In this way, the two blocking strips 16 will be separated from the two mud discharge grooves 26 respectively. Thus, the furnace that needs to lay fireproof mud can be sleeved on the two long boxes 8. Then start the rotary drive to drive the rotary rod 3 to rotate, so that the two long boxes 8 can rotate. In this way, the mud in the long boxes 8 can be laid in the furnace. At the same time, the fireproof mud is scraped by the two inclined plates 9 and the two soft plates 7 to make the fireproof mud evenly laid on the furnace body. Connecting strips 11 are fixedly installed on the mutually close sides of the two moving strips 14. Square tubes 2 are movably sleeved on the two connecting strips 11. The two square tubes 2 are both fixedly connected to the rotary rod 3. Two notches 30 are provided on each of the two square tubes 2. Chute grooves 32 are provided on the left sides of the two connecting strips 11. Pressure springs a31 are fixedly installed on the right inner walls of the two chute grooves 32. The left ends of the two pressure springs a31 are both fixedly installed with limit posts 29. The two limit posts 29 are respectively movably connected to the two chute grooves 32. After moving the limit post 29 to the right, the connecting strip 11 can be moved in the square tube 2, so that the two moving strips 14 can move back and forth. In this way, the two blocking strips 16 can be moved. After moving the limit post 39 to different notches 30 on the square tube 2, the blocking strip 16 can be fixed at different positions, so as to facilitate the user to use. Small plates 12 are fixedly installed on the left sides of the two connecting strips 11. Hemispherical blocks 28 are fixedly installed on the left ends of the two limit posts 29. Four reinforcing rods 4 are fixedly installed on the rotary rod 3. The four reinforcing rods 4 are respectively fixedly connected to the mutually close sides of the two long boxes 8. The two moving strips 14 are respectively movably sleeved on the four reinforcing rods 4. The stability between the two long boxes 8 and the rotary rod 3 can be improved through the four reinforcing rods 4, and the fixing effect of the long box 8 can be improved. The small plate 12 can facilitate the user to move the connecting strip 11.Through the hemispherical block 28, the user only needs to press the limit post 29 into the sliding groove 32. After that, the finger does not need to be inserted into the notch. When moving the connecting bar 11 by using the arc surface of the hemispherical block 28, the limit post 29 can be completely pushed into the sliding groove 32 by extrusion. There are two square plates 33 on each of the two long boxes 8. The right-side square plates 33 on the two long boxes 8 are respectively fixedly connected to the corresponding long boxes 8. The left-side square plates 33 on the long boxes 8 are respectively attached to the corresponding long boxes 8. Small rods 22 are movably sleeved on the two right-side square plates 33. Fixed blocks 21 are fixedly installed on the two small rods 22. The four fixed blocks 21 are respectively fixedly connected to the two long boxes 8. Nuts a23 are threadedly sleeved on the two small rods 22. Movable rods 19 are fixedly installed on the two inclined plates 9. The two movable rods 19 respectively pass through the four square plates 33 movably. Nuts b20 are movably threadedly sleeved on the two movable rods 19. After rotating and removing the nut b20, the corresponding inclined plate 9 can be rotated back and forth, so that the user can conveniently adjust the angle of the inclined plate 9. In this way, the angle of the corresponding flexible plate 7 can be adjusted. Thus, the user can adjust the angle of the inclined plate 9 according to the thickness to be laid. In this way, the thickness of the fireproof putty laid will also be adjusted accordingly. Thus, it is convenient for the user to lay the fireproof putty into different thicknesses according to the needs. A number of connecting rods 35 are fixedly installed on the two inclined plates 9. Nuts c34 are threadedly sleeved on each of the connecting rods 35. Long strips 10 are arranged on the two inclined plates 9. A number of connecting grooves 13 are opened on the two long strips 10. Each connecting rod 35 is respectively movably connected to each connecting groove 13. After removing the nut c34, the long strip 10 can be removed, so that the flexible plate 7 can be removed. Thus, it is convenient for the user to replace different flexible plates 7. Thus, by replacing flexible plates 7 with different toughnesses and different styles, the effect of scraping the fireproof putty when laying the fireproof putty can be different by the flexible plates 7 with different toughnesses and different styles, and different styles can be presented on the surface of the fireproof putty during laying. Pressure strips 24 are movably connected in the two long boxes 8. The two pressure strips 24 are respectively movably sleeved on each moving rod 17. Pressure springs b18 are movably sleeved on each moving rod 17. Each pressure spring b18 is fixedly connected to one side of the two pressure strips 24 close to each other. Each pressure spring b18 is fixedly connected to the inner side wall of each long box 8 close to each other. By the extrusion of the pressure spring b18, pressure can be continuously applied to the direction in which the pressure strips 24 are away from each other. In this way, the fireproof putty is injected between the pressure strip 24 and the corresponding mud outlet groove 26. In this way, when the moving strip 14 is used to drive the blocking strip 16 to move and separate from the mud outlet groove 26, the pressure applied by the pressure spring b18 can drive the pressure strip 24 to slowly move in the direction away from each other, so as to cooperate with the centrifugal force to promote the fireproof putty to be laid on the furnace body through the mud outlet groove 26. Limit frames 25 are respectively attached to one side of the two pressure strips 24 away from each other. The two limit frames 25 are respectively fixedly connected to the inner side walls of the two long boxes 8. Sealing frames 27 are movably sleeved on the two blocking strips 16.The sealing frame 27 is fixedly connected to the inner side walls of the two mud discharge grooves 26. Through the limiting frame 25, it is possible to prevent the pressure strip 24 from fitting against the inner side walls of the two long boxes 8 that are moving away from each other. In this way, it can be avoided that there is no gap between the pressure strip 24 and the mud discharge groove 26. Therefore, after setting the connection between the rotating box 5 and the two long boxes 8 between the limiting frame 25 and the corresponding mud discharge groove 26, when injecting fireproof mud, the fireproof mud will enter the space between the pressure strip 24 and the mud discharge groove 26. Thus, after blocking the mud discharge groove 26 with the blocking strip 16, the injected fireproof mud will squeeze the pressure strip 24 to move, so that the pressure spring b18 can contract and store energy.

[0030] During use, the first step: Inject fireproof mud into the rotating box 5 through the mud adding box 6. The fireproof mud will enter the two long boxes 8 through the rotating box 5. After the injection of the fireproof mud is completed, the mud adding box 6 can be closed, and then move the moving strip 14 in the direction of approaching each other. Thus, the two blocking strips 16 can be driven by the moving rod 17 to move in the direction of approaching each other. In this way, the two blocking strips 16 will be separated from the two mud discharge grooves 26 respectively. Then, the furnace chamber that needs to be laid with fireproof mud can be sleeved on the two long boxes 8, and then start the rotation drive to drive the rotating rod 3 to rotate. Thus, the two long boxes 8 can rotate, and the mud in the long boxes 8 can be laid in the furnace chamber. At the same time, the fireproof mud is scraped by the two inclined plates 9 and the two soft plates 7 to make the fireproof mud evenly laid on the furnace body.

[0031] The second step: After moving the limiting column 29 to the right, the connecting strip 11 can be moved inside the square tube 2. Thus, the two moving strips 14 can move back and forth, and the two blocking strips 16 can be moved. After moving the limiting column 39 to different notch openings 30 on the square tube 2, the blocking strip 16 can be fixed at different positions, which is convenient for users to use.

[0032] The third step: The stability between the two long boxes 8 and the rotating rod 3 can be improved through the four reinforcing rods 4, and the fixing effect of the long box 8 can be enhanced. The small plate 12 is convenient for users to move the connecting strip 11. With the hemispherical block 28, users only need to press the limiting column 29 into the sliding groove 32. The fingers do not need to be inserted into the notch opening. When moving the connecting strip 11 by using the arc surface of the hemispherical block 28, the limiting column 29 can be completely pushed into the sliding groove 32 by extrusion.

[0033] The fourth step: After removing the rotating moving nut b20 by rotating it, the corresponding inclined plate 9 can be rotated back and forth. Thus, it is convenient for users to adjust the angle of the inclined plate 9, and then the angle of the corresponding soft plate 7 can be adjusted. Thus, users can adjust the angle of the inclined plate 9 according to the thickness to be laid. The thickness of the laid fireproof mud will also be adjusted accordingly. Thus, it is convenient for users to lay the fireproof mud with different thicknesses according to the requirements.

[0034] Step 5: After removing the nut c34, the long strip 10 can be taken off, and thus the flexible board 7 can be taken off. This enables the user to conveniently replace different flexible boards 7. By replacing flexible boards 7 with different toughness and different styles, the effect of scraping the fireproof putty during the laying process can be different, and different styles can be presented on the surface of the fireproof putty during laying.

[0035] Step 6: Through the extrusion of the compression spring b18, pressure can be continuously applied in the direction in which the pressure strips 24 move away from each other. Then, the fireproof putty is injected between the pressure strips 24 and the corresponding mud outlet grooves 26. After the blocking strip 16 is driven by the moving strip 14 to move away from the mud outlet groove 26, the pressure applied by the compression spring b18 can drive the pressure strips 24 to slowly move away from each other, thereby promoting the fireproof putty to be laid on the furnace body through the mud outlet groove 26 in cooperation with the centrifugal force.

[0036] Step 7: The limit frame 25 can prevent the pressure strips 24 from fitting against the inner walls of the two long boxes 8 that move away from each other, thus avoiding no gap between the pressure strips 24 and the mud outlet grooves 26. After the connection between the rotating box 5 and the two long boxes 8 is arranged between the limit frame 25 and the corresponding mud outlet grooves 26, when injecting the fireproof putty, the fireproof putty will enter between the pressure strips 24 and the mud outlet grooves 26. After the blocking strip 16 blocks the mud outlet groove 26, the injected fireproof putty will squeeze the pressure strips 24 to move, so that the compression spring b18 can contract and store energy.
