AI Technical Summary
In existing flue manufacturing equipment, the reinforcing material layer is prone to warping and displacement, making it impossible to ensure the thickness of the protective layer. The finished product may have problems with cavities and inner wall smoothness, and the poor fluidity of cement mortar makes forming difficult, resulting in a low pass rate.
The process employs a spraying technique combined with an inner mold and a sliding pressure strip device. The inner mold is fixed by a base plate and positioning screws to ensure that the reinforcing material layer is centered. A mortar layer is sprayed around the inner mold to avoid the use of an outer mold and achieve flue formation.
Ensure that the finished flue has a sufficient protective layer thickness to avoid problems with cavity and inner wall smoothness, improve the finished product qualification rate, simplify the mold structure, adapt to flue forming of different heights and widths, and reduce costs.

TECHNICAL FIELD
[0001] The present application relates to the flue manufacturing technical field, especially to a flue manufacturing device and a manufacturing method thereof. BACKGROUND
[0002] The flue manufacturing device in the prior art mainly comprises an inner mold and an outer mold, the shapes of the inner mold and the outer mold are the same, and both are formed into a cuboid shell structure, the size of the outer mold is larger than that of the inner mold, and finally, grouting is performed between the inner mold and the outer mold to realize the production of the flue, and then, the mold is removed.
[0003] The disadvantages of the prior art are: 1. A reinforcing material layer is placed between the inner mold and the outer mold, and in an ideal condition, the reinforcing material layer is in a set position (generally, the center) through a support and a cushion stone to ensure that the flue has a sufficient protective layer thickness after forming, but in actual production process, because the layout area of the flue is large, the reinforcing material layer is not a rigid product, the reinforcing material layer often warps at positions without a support and a cushion stone, and may be displaced when a vibrating device vibrates the mortar, and finally, it is impossible to ensure that the flue has a sufficient protective layer thickness, and thus, the net may be exposed.
[0004] 2. In the prior art, grouting is performed between the outer mold and the inner mold, and thus, it is impossible to visually check, and thus, it is impossible to completely avoid the occurrence of product cavities, and the smoothness of the inner wall of the flue may also be problematic, and thus, the qualified rate of the finished product cannot be maximized.
[0005] 3. In addition, the flue is usually a thin-walled component with a thickness of about 15 mm, and after the traditional inner and outer mold structures are fixed, the 15-mm gap is grouted, and the fluidity of the cement mortar is very poor, which leads to forming difficulty, and in order to solve the fluidity, a large amount of water must be added for dilution, which leads to a serious imbalance of the water-cement ratio, and the product quality is greatly reduced.
[0006] Therefore, it is necessary to develop a flue manufacturing device and a manufacturing method thereof to solve the above problems. SUMMARY
[0007] The purpose of the present application is to design a flue manufacturing device and a manufacturing method thereof to solve the above problems.
[0008] The present application achieves the above-mentioned purpose through the following technical solutions: A flue manufacturing device comprises: a bottom plate; two flue dies, which are installed above both ends of the bottom plate and are parallel to each other; an inner mold, which is installed in the two flue dies, and a gap is arranged between the bottom of the inner mold and the bottom plate.
[0009] Specifically, the chimney die head comprises: a die head outer frame; a first positioning block, which is arranged below the top of the die head outer frame and has a first screw hole arranged vertically thereon; a screw rod, which is threadedly connected with the first screw hole; a sliding pressing strip, the lower end of the screw rod penetrating through the die head outer frame and the first positioning block and abutting against the upper portion of the sliding pressing strip, and the inner die being arranged in the die head outer frame and the lower end of the sliding pressing strip abutting against the upper end of the inner die.
[0010] Preferably, the die head outer frame is formed in a rectangular shape.
[0011] Further, the die head outer frame comprises an upper support, a lower support, a first side support and a second side support, and the upper support, the first side support, the lower support and the second side support are sequentially connected end to end.
[0012] Further, the die head further comprises a second positioning block, which is formed in a cuboid shape and has a second screw hole arranged vertically thereon, and the upper support is provided with a limiting slot penetrating through the upper support, and the second positioning block is rotationally arranged in the limiting slot in a limiting manner, and the circumferential dimension of the first positioning block is greater than that of the second positioning block, and the screw rod is threadedly connected with the second screw hole.
[0013] Preferably, the top center of the sliding pressing strip is provided with a positioning hole, and the positioning hole is a blind hole, and the lower end of the screw rod is arranged in the blind hole.
[0014] Specifically, the two ends of the sliding pressing strip are respectively connected with a first sliding block and a second sliding block, a first sliding groove is vertically arranged on the first side support, and a second sliding groove is vertically arranged on the second side support, and the first sliding block is arranged in the first sliding groove in a limiting and sliding manner, and the second sliding block is arranged in the second sliding groove in a limiting and sliding manner.
[0015] Specifically, the top of the screw rod is connected with the middle of a handle.
[0016] A manufacturing method of a manufacturing device of a chimney, comprising the following steps: S1, spraying an outer mortar layer with a thickness of half of the chimney on the top of a base plate; S2, laying a reinforcing material layer on the top of the outer mortar layer, the width of the reinforcing material layer being greater than the circumference of the chimney, and the length of the reinforcing material layer being equal to the length of the chimney; S3, spraying an inner mortar layer with a thickness of half of the chimney on the top of the reinforcing material layer on the top of the base plate; S4, arranging an inner die above the inner mortar layer on the top of the base plate; S5, spraying an inner mortar layer with a thickness of half of the chimney on three surfaces of the inner die except the bottom; S6. Bend the reinforcing material layer to the surface of the inner mortar layer from the previous step, and then fix the reinforcing material layer together. S7. Spray an outer mortar layer half the thickness of the flue onto the surface of the bottom reinforcing material layer; S8. After demolding, the flue is obtained.
[0017] Further, step S4 specifically includes: first, rotating the screw upwards by rotating the screw in the first direction with the handle, then moving the sliding pressure strip upwards, placing both ends of the inner mold inside the outer frame of the two flue mold heads respectively, placing the inner mold below the sliding pressure strip, and then rotating the screw downwards by rotating the screw in the second direction with the handle until it presses down against the sliding pressure strip and tightens the inner mold.
[0018] The beneficial effects of this invention are as follows: The flue manufacturing apparatus in this application is designed to complement the manufacturing method, enabling the formation of the flue around the inner mold through a spraying process. The base plate serves as the foundation for the bottom support of the flue, prioritizing the formation of the flue bottom and the positioning and installation of the reinforcing material layer. Finally, the inner mold is installed, sequentially completing the installation and forming of the remaining inner mortar layer, reinforcing material layer, and outer mortar layer of the flue. In this application, by first spraying an inner mortar layer half the thickness of the flue, followed by the laying of the reinforcing material layer and the outer mortar layer, the reinforcing material layer is ensured to be centrally positioned, guaranteeing sufficient protective layer thickness for the flue and preventing exposed mesh. Furthermore, the reinforcing material layer is installed as a single piece and then bent into shape, resulting in high work efficiency.
[0019] In addition, because the flue is formed using a spraying process, no outer mold is used. Therefore, the problem of poor cement mortar fluidity and forming difficulties caused by the small gap between the inner and outer molds in traditional technology is avoided. The flue produced by this application will basically not have cavities or poor smoothness of the inner wall of the flue, thus maximizing the qualification rate of the finished product.
[0020] By adjusting the height of the sliding pressure bar by rotating the screw, this application can be adapted to the forming of flues of different heights; in addition, by rotating the flue manufacturing device of this application by 90 degrees, it can be adapted to the forming of flues of different widths, making the application more widely applicable and saving costs.

They are only used to facilitate the description of this invention and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0027] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0028] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, terms such as "set" and "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0029] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0030] like Figures 1-3 As shown, an apparatus for manufacturing a flue includes: Base plate 1; Two flue mold heads 3; the two flue mold heads 3 are respectively installed above the two ends of the base plate 1, and the two flue mold heads 3 are parallel to each other; Inner mold 4; the two ends of the inner mold 4 are respectively installed in the two flue mold heads 3, and a gap is provided between the bottom of the inner mold 4 and the base plate 1.
[0031] The flue mold head 3 in this application only needs to be used to fix the inner mold 4. Compared with the complex structure of the prior art that requires fixing both the inner mold 4 and the outer mold, the flue mold head 3 in this application has a simple structure and can achieve rapid positioning and installation of the inner mold 4. In addition, this application does not have an outer mold, making the overall structure easier to assemble and use.
[0032] In some embodiments, such as Figure 5 As shown, the flue head 3 includes: outer frame of the mold head; First positioning block 16; The first positioning block 16 is located below the top of the outer frame of the mold head, and a first screw hole 18 is vertically provided on the first positioning block 16; Screw 15; Screw 15 is threaded into the first screw hole 18; The lower end of the sliding pressure bar 12 passes downward through the outer frame of the mold head and the first positioning block 16 and then presses against the upper part of the sliding pressure bar 12. The inner mold 4 is placed inside the outer frame of the mold head, and the lower end of the sliding pressure bar 12 presses against the upper end of the inner mold 4.
[0033] In some embodiments, such as Figure 5 As shown, the outer frame of the mold head is formed into a rectangle.
[0034] In some embodiments, such as Figure 5 As shown, the outer frame of the mold head includes an upper support 5, a lower support 6, a first side support 7, and a second side support 8, which are connected end to end in sequence.
[0035] In some embodiments, such as Figure 4 and 5 As shown in Figure 7, the flue head 3 also includes a second positioning block 17, which is rectangular in shape. A second screw hole is vertically provided on the second positioning block 17. A vertically extending limiting groove 9 is provided inside the upper bracket 5. The second positioning block 17 is circumferentially rotated and limited within the limiting groove 9. The circumferential dimension of the first positioning block 16 is larger than that of the second positioning block 17. The screw 15 is threaded into the second screw hole. The circumferential rotation limiting cooperation between the second positioning block 17 and the limiting groove 9 serves both to limit the upward movement of the second positioning block 17 and to prevent the upper surface of the second positioning block 17 from rotating only through frictional resistance with the bottom of the upper bracket 5. The second positioning block 17 cannot be locked into the limiting groove 9.
[0036] In some embodiments, such as Figure 5 and 6As shown, a positioning hole 20 is provided at the top center of the sliding pressure strip 12. The positioning hole 20 is a blind hole, and the lower end of the screw 15 is placed inside the blind hole. The lower end of the screw 15 extends into the positioning hole 20 to tighten and engage with the sliding pressure strip 12, thereby limiting the circumferential swing of the sliding pressure strip 12 and making the clamping of the inner mold 4 more stable.
[0037] In some embodiments, such as Figures 4-6 As shown, the two ends of the sliding pressure strip 12 are respectively connected to a first slider 13 and a second slider 14. A first groove 10 is vertically formed on the first side bracket 7, and a second groove 11 is vertically formed on the second side bracket 8. The first slider 13 is slidably positioned within the first groove 10, and the second slider 14 is slidably positioned within the second groove 11. The guiding sliding cooperation between the sliders and the grooves serves to stabilize the movement of the sliding pressure strip 12, so as to achieve stable pressing of the sliding pressure strip 12 against the inner mold 4.
[0038] In some embodiments, such as Figure 5 As shown, the top of the screw 15 is connected to the middle of a handle 19. The handle 19 allows for convenient rotation of the screw 15.
[0039] In some embodiments, such as Figure 1 As shown, support legs are provided at the four corners below the base plate 1. The support legs provide support for the base plate 1.
[0040] In some embodiments, such as Figure 8 As shown, if the flue 24 manufacturing device of this application is rotated 90 degrees, the handle 19, screw 15 and sliding pressure strip 12 can be used to adjust and adapt to the forming of flues 24 of different widths, making the application scope of this application wider and saving costs.
[0041] This application also provides a method for manufacturing a flue gas duct manufacturing apparatus, comprising the following steps: S1, such as Figure 9 As shown, first spray an outer mortar layer 21 with a thickness of half that of the flue 24 onto the top of the base plate 1; S2, such as Figure 10 As shown, a reinforcing material layer 22 is then laid on top of the outer mortar layer 21. The width of the reinforcing material layer 22 is greater than the perimeter of the flue 24, and the length of the reinforcing material layer 22 is equal to the length of the flue 24. S3, such as Figure 11 As shown, an inner mortar layer 23, half the thickness of the flue 24, is sprayed on top of the reinforcing material layer 22 on the top of the base plate 1. S4, such as Figure 12As shown, the inner mold 4 is installed above the inner mortar layer 23 at the top of the base plate 1; specifically, the process includes first rotating the screw 15 in the first direction by the handle 19 to rotate the screw 15 upward, then moving the sliding pressure strip 12 upward, placing both ends of the inner mold 4 inside the outer frame of the two flue mold heads 3 respectively, with the inner mold 4 placed below the sliding pressure strip 12, and then rotating the screw 15 in the second direction by the handle 19 to rotate the screw 15 downward until it presses down against the sliding pressure strip 12 and presses the inner mold 4. S5, such as Figure 13 As shown, an inner mortar layer 23, half the thickness of the flue 24, is sprayed on the three surfaces of the inner mold 4, excluding the bottom. S6, such as Figure 14 As shown, bend the reinforcing material layer 22 to adhere to the surface of the inner mortar layer 23 from the previous step, and then fix the reinforcing material layer 22 by butt joint (according to the specifications); S7, such as Figure 15 As shown, an outer mortar layer 21, half the thickness of the flue 24, is sprayed onto the surface of the bottom reinforcing material layer 22. S8, such as Figure 16 As shown, after demolding, flue 24 is obtained.
[0042] In some embodiments, there are also some steps not shown in the prior art, such as the need to fix the structure of the inner mold 4 by internal support, which can be done by internal airbag inflation support or by support by a fixed bracket.
[0043] In some embodiments, the reinforcing material layer 22 may be selected as a mesh fabric or a wire mesh.
[0044] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
