DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0042] See also Figure 1-Figure 12The embodiment of the present invention provides a technical solution: a production device for a microporous lightweight calcium silicate insulation board, comprising a hydraulic device 4, an upper die seat 5 installed at the telescopic end of the hydraulic device 4, and an upper mold plate 6 fixed to the lower surface of the upper die seat 5, and also comprising a lower die seat 3, the upper surface of the lower die seat 3 is provided with a groove 14, a center plate 13 is installed in the middle of the groove 14, and triangular plates 11 are slidably installed at the four corners of the groove 14, preferably the triangular plate 11 is a right-angled isosceles triangle structure, and the bottom of the triangular plate 11 protrudes downward and is installed A scraper is abutted against the lower surface of the groove 14 to scrape off the waste liquid at the bottom of the groove 14. An L-shaped side plate 12 is fixed at the outer edge of the triangular plate 11. The triangular plate 11 slides toward the center plate 13 to form a molding cavity between the triangular plate 11, the center plate 13, and the L-shaped side plate 12 to realize the molding of the insulation board body 10. The molding of the side of the insulation board body 10 is realized by the abutment of the four L-shaped side plates 12. The molding of the bottom of the insulation board body 10 is realized by the cooperation of the four triangular plates 11 and the center plate 13.

[0043] In addition, to facilitate the unloading of the insulation board body 10 after molding, the production device of the microporous lightweight calcium silicate insulation board provided in this embodiment also includes a lifting column 18, which is installed in the middle part of the lower mold base 3, and the upper end of the lifting column 18 is fixedly connected to the lower surface of the center plate 13. The center plate 13 is driven upward by the lifting column 18, thereby realizing the lifting of the insulation board body 10 after molding, and the center plate 13 is driven downward by the lifting column 18, so that the center plate 13 and the triangular plate 11 are in the same horizontal plane, thereby enclosing a molding cavity.

[0044] In order to realize the lifting and lowering of the lifting column 18, the present solution further includes a linkage component, which is arranged at the lower end of the lower mold base 3 to drive the lifting column 18 to move up and down.

[0045] In addition, in order to make the lifting column 18 rise and fall to drive the triangular plate 11 away from the center plate 13 or close to the center plate 13, the production device of the microporous lightweight calcium silicate insulation board provided in this embodiment also includes a pushing component, which is arranged at the middle position of the groove 14 to drive the triangular plate 11 to slide inside the groove 14. It should be noted that in this scheme, the triangular plate 11 slides along the diagonal of the groove 14 to ensure that the triangular plate 11 can be aligned with the edge of the center plate 13, thereby forming a stable molding cavity, and the lifting column 18 is raised through the linkage component so that the pushing component pushes the triangular plate 11 away from the center plate 13, and further makes the four triangular plates 11 unfold, which is conducive to the separation of the side edge of the insulation board body 10 after molding and the L-shaped side plate 12, and further facilitates the lifting of the insulation board body 10, and the lifting column 18 is lowered through the linkage component so that the pushing component pushes the triangular plate 11 close to the center plate 13, and the center plate 13 cooperates to form a stable molding cavity between the triangular plate 11, the center plate 13, and the L-shaped side plate 12.

[0046] like Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the pushing assembly provided in this embodiment includes a transmission chamber 24, which is arranged at the middle position of the groove 14, and a shaft sleeve 21 is rotatably installed inside the transmission chamber 24. In addition, a push block 26 is also provided inside the transmission chamber 24, and the push block 26 is a four-pointed star structure, and the push block 26 is fixedly sleeved on the outside of the shaft sleeve 21, and a connecting track 31 is provided on the outer edge of the push block 26, and the connecting track 31 is preferably a continuous arc structure.

[0047] In addition, the push assembly provided in this embodiment also includes a push rod 25, which is fixed to the side of the triangular plate 11 facing the center plate 13, and one end of the push rod 25 extends into the transmission cavity 24 and is provided with a ball 32 adapted to the connecting track 31. The outer side of the push rod 25 is located between the triangular plate 11 and the outer wall of the transmission cavity 24 and is provided with a return spring 27. In this solution, the push block 26 is driven to rotate by the shaft sleeve 21. When the corner end of the push block 26 abuts against the ball 32, the connection track 31 on the push block 26 and the ball 32 are connected. 32 cooperates with the push rod 25 to move, so that the push rod 25 pushes the triangular plate 11 to slide inside the groove 14. At this time, the reset spring 27 stretches and stores elastic potential energy, and the sleeve 21 continues to drive the push block 26 to rotate. When the recessed part on the push block 26 faces the ball 32, at this time, the reset spring 27 contracts and the elastic potential energy is released, thereby pulling the triangular plate 11 to move toward the center plate 13, and making the ball 32 and the connecting track 31 always resist each other, thereby ensuring the stability of the triangular plate 11 when it moves.

[0048] like Fig.10 As shown, further, in order to ensure that the push block 26 rotates 45° each time, so that the push block 26 can stably drive the triangular plate 11 to move, a slider 33 is evenly installed on the inner side of the sleeve 21 near the lower end, and a second slide rail 28 compatible with the slider 33 is evenly provided on the outer side of the lifting column 18 near the lower end. It should be noted that the second slide rail 28 in this scheme is a spiral structure, and the projection directly above the second slide rail 28 is a 45° arc structure, so that when the lifting column 18 rises, the slider 33 slides from the uppermost end of the second slide rail 28 to the lowermost end of the second slide rail 28, and then the sleeve 21 rotates 45°. In this scheme, the vertical distance between the two ends of the second slide rail 28 is the lifting height of the lifting column 18.

[0049] like Figure 4 , Figure 5 , Figure 8 and Fig. 9As shown, in order to facilitate the resetting of the sleeve 21 after rotation, an equipment box 19 rotatably connected to the sleeve 21 is fixed at the top of the lower mold base 3, and a clockwork spring 20 is installed inside the equipment box 19. One end of the clockwork spring 20 is fixedly connected to the equipment box 19, and the other end of the clockwork spring 20 is fixedly connected to the outer side of the sleeve 21. When the lifting column 18 moves downward to drive the sleeve 21 to rotate, the clockwork spring 20 contracts. At this time, elastic potential energy is stored in the clockwork spring 20. When the elastic potential energy in the clockwork spring 20 is released, the clockwork spring 20 relaxes, so that the sleeve 21 rotates in the opposite direction, thereby driving the lifting column 18 upward.

[0050] like Figure 1 , Figure 4 , Figure 5 , Figure 8 and Fig.11 As shown, the linkage assembly provided in this embodiment includes a movable frame 9, which is slidably installed on the outer side of the lower mold base 3, and a horizontal plate 22 is fixed at the middle end of the movable frame 9 and fixedly connected to the lower end of the lifting column 18. The horizontal plate 22 is driven upward by the movable frame 9, so that the horizontal plate 22 pushes the lifting column 18 upward.

[0051] In order to improve the stability of the horizontal plate 22 during movement, the linkage assembly provided in this embodiment also includes square holes 17. The square holes 17 are symmetrically arranged on both sides of the lower mold base 3, and the square holes 17 are slidably connected to the horizontal plate 22, thereby ensuring the stability of the horizontal plate 22 and the movable frame 9 during lifting and lowering.

[0052] To facilitate driving the movable frame 9 downward, the linkage assembly provided in this embodiment also includes a side frame 7, which is fixed on both sides of the upper mold base 5, and a pressure plate 8 is fixed to the lower end of the outer side of the side frame 7. When the hydraulic device 4 drives the upper mold base 5 downward, the pressure plate 8 moves downward with the upper mold base 5, thereby pushing the movable frame 9 downward, and further driving the cross plate 22 downward. When the upper mold plate 6 enters the molding cavity and squeezes the insulation board body 10, the cross plate 22 moves downward to the lowest end. At this time, the lifting column 18 moves downward and makes the center plate 13 and the triangle plate 11 in the same horizontal plane, thereby forming a stable molding cavity between the triangle plate 11, the center plate 13, and the L-shaped side plate 12.

[0053] like Figure 1 , Figure 2 , Figure 3 and Fig.11 As shown, a baffle 16 is fixed to the outside of the L-shaped side plate 12 provided in this embodiment. The baffle 16 is an "L"-shaped structure, and the width of the baffle 16 is greater than the sliding distance of the triangular plate 11 to close the gap between the inner wall of the groove 14 and the outer wall of the L-shaped side plate 12.

[0054] like Figure 5 and Figure 6As shown, in order to ensure the stability of the triangle plate 11 when it moves, the present invention symmetrically opens a slide groove 30 at the lower end of the interior of the triangle plate 11, and opens an engaging groove 29 on one side of the triangle plate 11 facing the center plate 13, and a first slide rail 23 is provided at the lower end of the interior of the groove 14, and the first slide rail 23 is slidably connected to the slide groove 30 to improve the stability of the triangle plate 11 when it moves, and a cover plate 15 is fixed to the upper end of the transmission cavity 24, and the side of the cover plate 15 extends to the outside of the transmission cavity 24 and engages with the engaging groove 29. The engagement of the cover plate 15 with the engaging groove 29 improves the stability of the triangle plate 11 when it is connected to the center plate 13.

[0055] like Figure 1 and Fig.12 As shown, in order to facilitate the loading and unloading of the insulation board body 10, the production device of the microporous lightweight calcium silicate insulation board provided in this embodiment also includes a workbench 1 arranged at the lower end of the lower mold base 3, and a transfer assembly is provided on the workbench 1. The transfer assembly includes a slide 2, and a slide 38 is symmetrically opened on the lower surface of the slide 2. There are two lower mold bases 3, and the two lower mold bases 3 are symmetrically fixed on the upper surface of the slide 2. A third slide rail 37 is symmetrically installed on the upper surface of the workbench 1, and the third slide rail 37 is slidably connected to the slide 38.

[0056] The transfer assembly provided in this embodiment also includes a connecting plate 35, which is fixed to the lower surface of the slide 2. A through groove 36 adapted to the connecting plate 35 is opened on the workbench 1, and an electric telescopic cylinder 34 is fixed to the lower surface of the workbench 1 for driving the connecting plate 35 to slide inside the through groove 36.

[0057] In this scheme, the middle end of the upper surface of the workbench 1 is preferably a molding area, and its two sides are loading and unloading areas, wherein the molding area corresponds to the upper mold base 5, and the connecting plate 35 is driven by the electric telescopic cylinder 34 to slide inside the through groove 36, so that the slide 2 slides on the workbench 1. During the sliding process of the slide 2, there is always a lower mold base 3 located inside the molding area, which is beneficial to the continuous molding of the insulation board main body 10 and improves the production and processing efficiency of the insulation board main body 10.

[0058] like Figure 2 and Figure 3 As shown, in order to facilitate the discharge of internal moisture when the insulation board body 10 is formed, a first semicircular hole is evenly provided on the outer side of the center plate 13, and a second semicircular hole is provided on the side of the triangular plate 11 facing the center plate 13. The first semicircular hole and the second semicircular hole are adapted to be used for the discharge of waste liquid when the insulation board body 10 is pressurized and formed. By separating and combining the first semicircular hole and the second semicircular hole, the first semicircular hole and the second semicircular hole can be avoided from being blocked, thereby improving the water filtering effect. In addition, a drainage hole can also be provided at the lower end of the groove 14 for the discharge of waste liquid.

[0059] When in use (working), the blank is placed on the center plate 13, and the hydraulic device 4 is started so that the upper die seat 5 drives the upper die plate 6 downward, and further the pressing plate 8 moves downward along with the upper die seat 5, thereby pushing the movable frame 9 downward, thereby driving the cross plate 22 downward, and then the cross plate 22 drives the lifting column 18 downward. At this time, the slider 33 slides from the lower end of the second slide rail 28 to the upper end of the second slide rail 28, and then the shaft sleeve 21 rotates 45° and the spring spring 20 stores elastic potential energy. In this process, the shaft sleeve 21 drives the push block 26 to rotate. When the recessed part on the push block 26 faces the ball 32, at this time, the reset spring 27 contracts and its elastic potential energy is released. This pulls the triangular plate 11 toward the center plate 13, and makes the ball 32 and the connecting track 31 always counteract each other, thereby ensuring the stability of the triangular plate 11 when it moves. When the upper template 6 enters the molding cavity and squeezes the insulation board body 10, the cross plate 22 moves down to the lowest end. At this time, the lifting column 18 moves down and makes the center plate 13 and the triangular plate 11 in the same horizontal plane, thereby forming a stable molding cavity between the triangular plate 11, the center plate 13, and the L-shaped side plate 12, thereby forming the insulation board body 10. When the insulation board body 10 is formed, the excess water inside the blank enters the groove 14 from between the first semicircular hole and the second semicircular hole, thereby realizing the discharge of waste liquid.

[0060] After forming, the hydraulic device 4 drives the upper die seat 5 upward. At this time, the upper die seat 5 drives the pressure plate 8 upward, thereby releasing the restriction of the pressure plate 8 on the movable frame 9 and the cross plate 22, so that the elastic potential energy stored in the spring 20 is released, and the shaft sleeve 21 is further rotated in the opposite direction. In this process, the shaft sleeve 21 drives the push block 26 to rotate in the opposite direction, and the corner end of the push block 26 is against the ball 32, so that the push rod 25 is movable, so that the push rod 25 pushes the triangular plate 11 to slide in the groove 14. At this time, the reset spring 27 is extended. And store elastic potential energy, so that the triangular plate 11 is separated from the center plate 13, and the first semicircular hole and the second semicircular hole are separated and combined, which can avoid the blockage of the first semicircular hole and the second semicircular hole and improve the water filtering effect. In the process of rotation of the sleeve 21, through the sliding connection between the slider 33 and the second slide rail 28, the slider 33 slides from the uppermost end of the second slide rail 28 to the lowermost end of the second slide rail 28, and then the lifting column 18 moves upward to push the center plate 13 upward, so that the insulation board body 10 on the center plate 13 is separated from the lower mold base 3.

[0061] After the insulation board body 10 is lifted, the electric telescopic cylinder 34 is started to make the connecting plate 35 slide inside the through groove 36, so that the slide 2 slides on the workbench 1. During the sliding process of the slide 2, there is always a lower mold base 3 located inside the molding area, which is beneficial to the continuous molding of the insulation board body 10 and improves the production and processing efficiency of the insulation board body 10.

[0062] In addition, the present invention also provides a production process of a microporous light calcium silicate insulation board, using the production device of the microporous light calcium silicate insulation board of the right, comprising the following steps:

[0063] S1. Mixing and stirring: adding water and raw materials in a certain liquid-to-solid mass ratio into a mixer, stirring and mixing to obtain a mixed slurry. Preferably, the raw materials include 40-60% silica ash, 5-25% fly ash, 10-30% carbide slag, 5-15% cement and 5-15% glass fiber by dry weight. When mixing, the water-cement ratio is 2:3.

[0064] S2. Heating and gelling: putting the mixed slurry into a steam oven for steaming to obtain a gel. Preferably, the steaming temperature inside the steam oven is 80° C.-95° C. and the steaming time is 4-6 hours to ensure the gelling of the mixed slurry to the greatest extent.
