Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of forming equipment, and particularly relates to a forming device for high-strength light-weight thermal insulation brick production. BACKGROUND

[0002] As a key material widely used in building wall thermal insulation and heat insulation, the quality and performance of thermal insulation bricks directly affect the energy consumption of buildings and the comfort of living. High-strength light-weight thermal insulation bricks are increasingly favored in the market due to their excellent thermal insulation performance, lighter weight, and higher strength. However, there are still many problems to be solved in the current production process of high-strength light-weight thermal insulation bricks.

[0003] In traditional thermal insulation brick production, there are obvious defects in the raw material mixing link. Common mixing equipment cannot achieve sufficient and uniform mixing of various raw materials such as lightweight aggregate, cementitious material, and additives. This leads to differences in the performance of thermal insulation bricks in the subsequent forming and use process, and cannot guarantee that every product meets the standards of high strength and light weight. In addition, existing devices often cannot accurately control the pouring amount and pouring speed. When the pouring amount is too much, it will cause material waste, and the size of the formed thermal insulation brick does not meet the standard; when the pouring amount is too little, it will cause voids and other defects in the thermal insulation brick, seriously affecting its thermal insulation and strength performance. Unstable pouring speed may lead to uneven internal structure of the thermal insulation brick, further reducing product quality.

[0004] In addition, the forming process after pouring is usually completed by natural drying or simple heating in traditional processes, which not only takes a long time, but also cannot achieve integrated forming. Natural drying is greatly affected by environmental factors and has very low production efficiency, which cannot meet the demand of large-scale production. Simple heating methods cannot guarantee the consistency of the internal structure of the thermal insulation brick, and it is difficult to make the thermal insulation brick maintain light weight characteristics while achieving high strength.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Embodiment: as shown in Figure 1 — Figure 11 A forming device for producing high-strength lightweight thermal insulation bricks, the forming device comprising: a base 1 and a mixing mechanism, a pouring mechanism and a heating forming mechanism, the mixing mechanism is installed on the base 1, the mixing mechanism comprises an outer cylinder 2 fixedly installed on the base 1, an inner cylinder 3 rotatably installed in the inner circle of the outer cylinder 2, and each raw material is mixed by the inner cylinder 3.

[0035] The mixing mechanism further comprises a gear ring 5 fixedly installed with the inner cylinder 3, the gear ring 5 is engaged with a cylindrical gear 6, the cylindrical gear 6 is rotatably installed on the base 1, and the cylindrical gear 6 is connected with a power mechanism through a conical gear set one 7. A plurality of protrusions 4 are arranged in the inner cylinder 3, and when the inner cylinder 3 and the raw materials in the inner cylinder 3 rotate in the outer cylinder 2, the protrusions 4 are used to mix the raw materials uniformly, and the stirred raw materials enter the shunt cover 14 through the discharge pipe 13.

[0036] As shown in Figure 1 — Figure 4As shown, in the process of producing high-strength light-weight thermal insulation bricks, first, various raw materials are poured into the inner cylinder 3, including expanded perlite, floating beads, diatomite, etc. as aggregate, aluminate cement, phosphate, etc. as binder, ceramic fiber, nano silicon dioxide, etc. as reinforcing agent, and aluminum powder as foaming agent. After being put into the inner cylinder 3 according to a certain proportion, the cylindrical gear 6 rotatingly installed on the base 1 is driven to rotate by the power mechanism. Since the cylindrical gear 6 is engaged with the gear ring 5, the gear ring 5 will drive the inner cylinder 3 to rotate, thereby making the raw materials falling into the inner cylinder 3 rotate and making the raw materials mix more uniformly. The inner cylinder 3 is provided with a plurality of protrusions 4. On the one hand, the protrusions 4 can improve the uniformity of the raw materials, and on the other hand, the protrusions 4 can also play a role in rubbing and crushing the raw materials. The protrusions 4 can be set to irregular shapes, or can be set to trapezoidal, cylindrical, etc. The raw materials entering the inner cylinder 3 will gradually enter the flow distribution cover 14 through the discharge pipe 13.

[0037] The pouring mechanism is installed on the base 1, and the pouring mechanism includes the flow distribution cover 14, which is communicated with the inner cylinder 3 through the discharge pipe 13. The raw materials mixed in the inner cylinder 3 are poured into the outer frame 35 through the flow distribution cover 14.

[0038] The pouring mechanism further includes two groups of stirring shafts 23 rotatingly installed on the flow distribution cover 14. Each group of stirring shafts 23 includes two stirring shafts 23, and the stirring shafts 23 are provided with blades 24. The two groups of stirring shafts 23 are connected through a belt assembly four. One group of stirring shafts 23 is connected with the connecting shaft 25 through a belt assembly two 22, the connecting shaft 25 is rotatingly installed on the base 1, and the connecting shaft 25 is connected with the power mechanism through a belt assembly three 26.

[0039] The pouring mechanism further includes a baffle 17, which is provided with a plurality of second discharge ports 18. The baffle 17 is slidingly matched with the long groove one 15 arranged below the flow distribution cover 14, and the baffle 17 and the base 1 are provided with a reset spring one 19. The baffle 17 is fixedly installed with an arc block 20. The flow distribution cover 14 is provided with a plurality of first discharge ports 16 below.

[0040] As shown in Figure 5 , Figure 6 , Figure 7 , Figure 9 The flow distribution cover 14 is rotatingly installed with two groups of symmetrical stirring shafts 23. In the pouring process, the raw materials enter the flow distribution cover 14 through the discharge pipe 13. In order to prevent solidification in the flow distribution cover 14 and improve the fluidity of the raw materials, the blades 24 on the stirring shafts 23 are needed to continuously stir the raw materials in the flow distribution cover 14. The purpose of setting the blades 24 is to increase the stirring area. In order to make the view more intuitive and understand the scheme, Figure 7 The baffle 17 originally located inside the long groove one 15 is moved to the lower side of the flow distribution cover 14 for display.

[0041] In the initial state, the second discharging port 18 on the baffle 17 is not aligned with the first discharging port 16 below the flow divider 14, which is to ensure that the raw material in the flow divider 14 does not flow out of the first and second discharging ports 16 and 18 before the outer frame 35 reaches below the flow divider 14. During the movement of the outer frame 35 towards the flow divider 14 driven by the conveying belt 12, the outer frame 35 will contact the arc-shaped block 20 on the baffle 17. Since the arc-shaped block 20 is in the shape of a circular arc, the arc-shaped block 20 will drive the baffle 17 to slide along the first long slot 15 on the flow divider 14 under the extrusion of the surface of the outer frame 35, so that the first discharging port 16 below the flow divider 14 is aligned with the second discharging port 18 on the baffle 17. At this time, the outer frame 35 moves below the flow divider 14, and the raw material in the flow divider 14 will fall into the material cavity 36 provided on the outer frame 35 through the first and second discharging ports 16 and 18. With the continuous movement of the outer frame 35, the arc-shaped block 20 will not drive the baffle 17 to reset, and the first return spring 19 is always in a stretched state. After the outer frame 35 leaves the arc-shaped block 20, the baffle 17 is reset under the elastic force of the first return spring 19, and the second discharging port 18 and the first discharging port 16 are in the staggered state again, so that the raw material in the flow divider 14 will not fall. The movement of the outer frame 35 away from the arc-shaped block 20 means that the pouring of the raw material in all the material cavities 36 is completed.

[0042] The pouring mechanism further comprises a cross plate 27 which is in sliding fit with the second long slot 21 on the flow divider 14. One end of two driving arms 28 is rotatably connected to the cross plate 27, and the other end of the driving arms 28 is rotatably connected to the heating plate 29.

[0043] As shown in Figure 4 , Figure 8 , Figure 9 The flow divider 14 is provided with the second long slot 21, and the cross plate 27 is in sliding fit with the second long slot 21. During the pouring process, the cross plate 27 only contacts the edge of the second long slot 21 and does not extend into the interior of the flow divider 14. During the movement of the outer frame 35, the outer frame 35 will gradually approach the cover 34. When the pouring of the material cavities 36 on the outer frame 35 is completed, the outer frame 35 will move into the interior of the cover 34, and the rollers 38 on the carrier plate 37 will contact and press the pressing block 32, so that the pressing block 32 drives the heating plate 29 to move downwards along the cover 34. At this time, the heating plate 29 drives the driving arms 28 to move, so that the end of the driving arms 28 connected to the cross plate 27 moves towards the flow divider 14, so that the cross plate 27 extends into the interior of the flow divider 14. In this way, the raw material entering the flow divider 14 through the discharging pipe 13 can be blocked, and the waste of residual raw material can be reduced.

[0044] The heating and forming mechanism comprises a cover 34, a heating plate 29 is slidably installed in the interior of the cover 34, and a plurality of heating heads 30 are provided on the heating plate 29.

[0045] The heating forming mechanism further comprises a sliding frame 31 which is in sliding fit with the cover 34, and four press blocks 32 are fixedly installed on the sliding frame 31 and in sliding fit with the cover 34, and a reset spring 33 is arranged between the sliding frame 31 and the cover 34, and the sliding frame 31 is connected with the heating plate 29.

[0046] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 10 , Figure 11 During the movement of the object plate 37 and the outer frame 35 along with the conveying belt 12, the rollers 38 on the object plate 37 will be in contact with the press blocks 32 on the sliding frame 31 respectively, and since the press blocks 32 are in arc shape above and the sliding frame 31 can slide on the cover 34, the press blocks 32 will not restrict the movement of the rollers 38 along the press blocks 32, and when the four rollers 38 are in contact with the four press blocks 32 respectively, the press blocks 32 will move downward along the cover 34, thereby driving the heating plate 29 to move downward, on one hand, the driving arm 28 on the driving arm 28 drives the horizontal plate 27 to move into the inner part of the flow divider cover 14, and on the other hand, the heating plate 29 will move downward to the upper part of the outer frame 35 and be in contact with the outer frame 35, and then the heating head 30 heats each material cavity 36 to make the raw material in the material cavity 36 be formed. During the forming process, the conveying belt 12 will not rotate, i.e. the power mechanism will not work. The reset spring 33 assists the sliding frame 31 to reset after the forming is completed.

[0047] The power mechanism comprises a long shaft 8 which is rotatably installed on the base 1, one end of the long shaft 8 is connected with the cylindrical gear 6 through the conical gear set 1 7, the other end is connected with the horizontal shaft 10 through the conical gear set 2 9, the horizontal shaft 10 is rotatably installed on the base 1, the long shaft 8 is connected with the belt assembly 3 26, and the horizontal shaft 10 is connected with the power source.

[0048] Specifically, the power source is a motor 39, and the output shaft of the motor 39 is connected with the horizontal shaft 10.

[0049] As shown in Figure 1 , Figure 4 During the mixing, pouring and movement of the outer frame 35, power is provided by the motor 39, and the output shaft of the motor 39 can be directly connected with the horizontal shaft 10 which is rotatably installed on the base 1, or can be connected with the horizontal shaft 10 through a synchronous belt, which can be known and adopted by those skilled in the art.

[0050] By starting motor 39, the horizontal shaft 10 rotates on base 1. The horizontal shaft 10, through bevel gear set 2 9, drives the long shaft 8 to rotate on base 1. At this time, the long shaft 8, through bevel gear set 1 7, drives the cylindrical gear 6 to rotate, causing the cylindrical gear 6 to drive the gear ring 5 and inner cylinder 3 to rotate on outer cylinder 2. The belt assembly 3 26 connected to the long shaft 8 also drives the stirring shaft 23 to rotate, thereby stirring the raw materials falling into the diversion hood 14. Simultaneously, the belt assembly 11 connected to the horizontal shaft 10 drives the conveyor belt 12 to rotate on base 1.

[0051] It should be noted that in this embodiment, both the first bevel gear set 7 and the second bevel gear set 9 include two meshing driving bevel gears and driven bevel gears. By mounting the two gears on two different structures and maintaining their meshing, transmission can be achieved, which is existing technology. For example, if the driving bevel gear in the first bevel gear set 7 is fixedly mounted on the long shaft 8, and the driven bevel gear is fixedly connected to the cylindrical gear 6, the power on the long shaft 8 can be transmitted to the cylindrical gear 6. The same principle applies to the long shaft 8 driving the horizontal shaft 10 to rotate via the second bevel gear set 9.

[0052] Furthermore, belt assemblies 11, 22, 36, 12, and 4 each include two pulleys and a belt. The two pulleys are connected by the belt. By mounting the pulleys on the two structures that need to rotate, power transmission can be achieved. For example, if one pulley in belt assembly 11 is fixedly connected to the horizontal shaft 10, and the other pulley is connected to the shaft of the pulley on the conveyor belt 12, the power of the horizontal shaft 10 can be transmitted to the conveyor belt 12 through belt assembly 11, causing the conveyor belt 12 to rotate on the base 1. The arrangement of the pulleys is prior art, and those skilled in the art can understand and use it.

[0053] The forming device also includes a conveyor belt 12 rotatably mounted on the base 1. One end of the conveyor belt 12 is connected to one end of the belt assembly 11, and the other end of the belt assembly 11 is connected to the horizontal shaft 10. The conveyor belt 12 is connected to the carrying plate 37. An outer frame 35 is installed above the carrying plate 37, and four oppositely arranged rollers 38 are provided below the carrying plate 37.

[0054] Specifically, multiple material cavities 36 can be arranged inside the outer frame 35. During the casting process, each material cavity 36 can be filled with raw materials.

[0055] like Figure 11 As shown, the outer frame 35 is detachably mounted on the upper part of the carrying plate 37. The carrying plate 37 is connected to the conveyor belt 12. When the conveyor belt 12 rotates, it will drive the carrying plate 37 and the outer frame 35 on the carrying plate 37 to move.

[0056] The above examples are only used to illustrate the technical solutions of the present application, but not to limit the present application; the technical features in the above examples or different examples can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as above, which are not provided in details for simplicity; although the present application is described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
