[0002] Autoclaved aerated concrete (AAC) blocks, also known as autoclaved aerated concrete blocks, are porous, lightweight concrete products made primarily from siliceous and calcareous materials, with the addition of a foaming agent. They are produced through a process of batching, mixing, pouring, static curing, cutting, and autoclaving. Containing numerous uniform and fine pores, they possess excellent properties such as lightweight, high strength, thermal insulation, sound insulation, and fire resistance. Widely used in building walls and roof insulation, they are an important building material for achieving energy conservation and green construction.
[0003] In the production process of aerated concrete blocks, the mixing of raw materials directly affects the pore structure, strength, and stability of the blocks.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-4 An embodiment of this utility model provides a raw material mixing device for aerated concrete block production, including a double-layer frame 1, a mixing tank 2 fixedly connected to the top of the double-layer frame 1, a mixing mechanism 3 provided inside the mixing tank 2, the mixing mechanism 3 being used to mix the raw materials, a discharge mechanism 4 provided at the bottom inner side of the double-layer frame 1, the discharge mechanism 4 being used to improve the convenience of discharge, an electromagnetic connection valve 7 connected to the bottom end of the mixing tank 2, the mixing tank 2 and the discharge mechanism 4 being connected through the electromagnetic connection valve 7, a three-way feed pipe 5 connected to the top right side of the mixing tank 2, and connecting flanges 6 fixedly connected to the front and rear ends of the right side of the three-way feed pipe 5;
[0034] The stirring mechanism 3 includes a cover plate 31, which is set on the top of the stirring tank 2. A stirring motor 32 is fixedly connected to the top of the cover plate 31. A stirring shaft 33 is fixedly connected to the output end of the stirring motor 32. Cross stirring impellers 34 are fixedly connected to the upper and lower outer sides of the stirring shaft 33. Impeller grooves 35 are opened on the upper and lower inner sides of the stirring tank 2. The outer sides of the two cross stirring impellers 34 are slidably connected inside the two impeller grooves 35 respectively. The stirring mechanism 3 also includes a support frame 36, which is fixedly connected to the bottom inner side of the stirring tank 2. The bottom end of the stirring shaft 33 is rotatably connected to the top of the support frame 36. The stirring mechanism 3 also includes multiple fixing bolts 37, which are equidistantly inserted around the top of the cover plate 31. The ends of the multiple fixing bolts 37 are threaded to the outer top of the stirring tank 2 respectively.
[0035] Specifically, the stirring mechanism 3 stirs and mixes the raw materials. The cover plate 31, made of Q235 steel plate with a thickness of 8mm, covers the top of the mixing tank 2. It is threadedly connected to the outer side of the top of the mixing tank 2 by multiple evenly distributed fixing bolts 37, forming a detachable sealed structure. The stirring motor 32 is fixed to the top of the cover plate 31, and its output end is connected to the stirring shaft 33. The stirring shaft 33 vertically penetrates the interior of the mixing tank 2. A set of cross-shaped stirring impellers 34 are fixed to the upper and lower parts of its outer side. The cross-shaped stirring impellers 34 are... Made of wear-resistant alloy steel, the blade edges are hardened to improve wear resistance. Impeller grooves 35 are correspondingly formed in the upper and lower middle parts of the inner side of the mixing tank 2. The groove width of the impeller groove 35 is clearance-fitted with the outer diameter of the cross-shaped stirring impeller 34, allowing the outer side of the cross-shaped stirring impeller 34 to slide within the impeller groove 35. This restricts the radial displacement of the impeller while allowing it to rotate around the stirring shaft 33. The support frame 36 fixed at the bottom of the inner side of the mixing tank 2 is made of cast steel and provides a rotation fulcrum for the bottom end of the stirring shaft 33. When the stirring motor 32 is started... The driving shaft 33 rotates, causing the cross-shaped stirring impeller 34 to rotate within the impeller groove 35. The upper cross-shaped stirring impeller 34 agitates the upper raw materials, while the lower cross-shaped stirring impeller 34 mixes the bottom raw materials. The limiting function of the impeller groove 35 ensures stable impeller operation during the stirring process, preventing collisions with the barrel wall. Simultaneously, the two sets of cross-shaped stirring impellers 34 form upper and lower layered stirring. Since the pressure generated by the rotation of the two sets of cross-shaped stirring impellers 34 is in opposite directions, it enables the raw materials to form three-dimensional convection within the mixing barrel 2, achieving uniform mixing. The three-way feed pipe 5 on the top right side of the mixing barrel 2 is connected to the external raw material conveying pipeline through the connecting flange 6, enabling simultaneous feeding of multiple raw materials. The electromagnetic connection valve 7 at the bottom of the mixing barrel 2 controls the connection and disconnection between the mixing barrel 2 and the discharge mechanism 4. The discharge mechanism 4 at the bottom inner side of the double-layer frame 1 is responsible for conveniently outputting the stirred raw materials. Through the layered stirring design and stable limiting structure of the stirring mechanism 3, combined with the coordinated operation of the feeding and discharging components, the effect of efficient and uniform mixing of raw materials is achieved during the production of aerated concrete blocks.
[0036] Reference Figure 1 , Figure 2 and Figure 5The discharge mechanism 4 includes a collection box 41, which is fixedly connected to the top of the inner side of the double-layer frame 1. A guide plate 42 is fixedly connected to the right side of the inside of the collection box 41. Two hydraulic rods 43 are provided on the right side of the collection box 41. A push plate 44 is fixedly connected to the left end of each of the two hydraulic rods 43. A discharge pipe 45 is connected to the bottom left side of the collection box 41. A telescopic pipe 46 is connected to the left end of the discharge pipe 45. An electromagnetic butterfly valve 47 is installed in the middle of the discharge pipe 45. The discharge mechanism 4 also includes multiple fixing blocks 48, which are fixedly connected to the front and rear ends of the bottom inner side of the double-layer frame 1. Two hydraulic rods 43 are fixedly connected to the inside of the two front fixing blocks 48 and the two rear fixing blocks 48, respectively. An observation component 49 is provided on the front side of the collection box 41. The observation component 49 includes an observation window 491, which is nested in the front side of the collection box 41. A scale line 492 is fixedly connected to the left end of the front side of the observation window 491.
[0037] Specifically, the collection box 41 is welded from Q235 steel plate with a wall thickness of 6mm. It is fixed to the top of the inner side of the double-layer frame 1. The guide plate 42 on the right side inside is made of 304 stainless steel with a smooth surface and is inclined at a 10° angle to the horizontal plane. It is used to guide the mixed raw materials to flow to the left. The two hydraulic rods 43 on the right side of the collection box 41 are connected to the double-layer frame 1 through the front and rear fixing blocks 48. The fixing blocks 48 are cast steel parts with mounting holes inside. The cylinders of the hydraulic rods 43 are embedded in them and fastened with bolts. The piston rod of the pressure rod 43 has a push plate 44 fixed to its left end. The push plate 44 is a composite structure of hard rubber plate and steel plate, with its edge in clearance fit with the inner wall of the collection box 41. It can slide left and right along the inner wall of the collection box 41 under the drive of the hydraulic rod 43. The discharge pipe 45 at the bottom left side of the collection box 41 is connected to the inside of the collection box 41. The electromagnetic butterfly valve 47 installed in the middle controls the discharge on and off. The telescopic pipe 46 at the left end of the discharge pipe 45 is made of stainless steel corrugated pipe, which can be axially extended and retracted to adapt to receiving equipment in different positions. The observation window of the observation component 49 is also included. Material 491 is made of tempered glass and is nested in front of the collection box 41. The scale line 492 on the left side of its front is made by etching and is used to indicate the height of the raw material in the collection box 41. When the electromagnetic connection valve 7 is opened, the stirred raw material falls from the mixing tank 2 into the collection box 41 and is guided to the left by the guide plate 42. After the electromagnetic butterfly valve 47 is opened, the raw material is discharged through the discharge pipe 45 and the telescopic pipe 46. If the raw material has insufficient flowability or accumulates, the hydraulic rod 43 drives the push plate 44 to move to the left, pushing the raw material toward the discharge. Pipe 45 ensures smooth material discharge. Through observation window 491 and scale line 492, the amount of raw material in collection box 41 can be monitored in real time. The adjustability of telescopic pipe 46 allows the discharge port position to be adjusted according to needs, adapting to different specifications of receiving equipment. The composite structure of push plate 44 ensures sealing performance with box wall and avoids wear on box wall. The smooth surface of guide plate 42 reduces raw material adhesion and improves discharge efficiency, achieving efficient and controllable output of mixed raw materials in the production process of aerated bricks.
[0038] Reference Figure 1 and Figure 2 Multiple triangular bracing plates 8 are fixedly connected at equal intervals on the outer side of the mixing tank 2. The bottom ends of the multiple triangular bracing plates 8 are fixedly connected to the top outer side of the double-layer frame 1. Multiple diagonal bracing rods 9 are fixedly connected to the inner side of the double-layer frame 1. The top ends of the multiple diagonal bracing rods 9 are fixedly connected at equal intervals around the bottom of the mixing tank 2.
[0039] Specifically, the triangular bracing plates 8, which are equidistantly fixed on the outside of the mixing tank 2, are made of Q235 steel plate with a thickness of 5mm. Their tops are welded to the outside of the mixing tank 2, and their bottoms are fixed to the top outside of the double-layer frame 1. The triangular bracing plates 8 are right-angled triangles. Utilizing the stability of the triangle, part of the load on the mixing tank 2 is transferred to the double-layer frame 1, reducing stress concentration at the connection between the mixing tank 2 and the double-layer frame 1. The diagonal bracing rods 9 on the inside of the double-layer frame 1 are Q235 steel pipes with an outer diameter of 30mm and a wall thickness of 3mm. Their bottoms are welded to the inside of the double-layer frame 1, and their tops are equidistantly fixed around the bottom of the mixing tank 2. The diagonal bracing rods 9 and the bottom of the mixing tank 2 form a... Multi-angle support further disperses the vibration and torque generated during the mixing process, enhancing the installation stability of the mixing tank 2. The triangular brace plate 8 and the diagonal brace rod 9 together form a spatial support structure: the triangular brace plate 8 mainly bears the horizontal force, limiting the radial sway of the mixing tank 2; the diagonal brace rod 9 bears the vertical force, preventing the vertical displacement of the mixing tank 2. The two work together to ensure that the mixing tank 2 remains stable when the mixing motor 32 is running, avoiding loose connections or component damage caused by vibration. This achieves the effect of improving the installation stability of the mixing tank 2 and ensuring the reliable operation of the mixing device during the mixing of aerated brick raw materials.
[0040] Working Principle: The device uses a double-layer frame 1 as its basic supporting structure. The top of the frame is fixedly connected to the mixing tank 2, and the bottom inner side is equipped with a discharge mechanism 4, forming a spatial layout of upper mixing and lower discharge. The mixing tank 2, as the core processing component, is connected to an external raw material conveying pipeline via a three-way feed pipe 5 on the top right side, enabling simultaneous feeding of multiple raw materials. The bottom end is connected to the discharge mechanism 4 via an electromagnetic valve 7, controlling the flow direction and timing of the raw materials. The double-layer frame 1 not only provides installation support for the mixing tank 2 and the discharge mechanism 4, but also features triangular bracing plates 8 and bracing rods 9 between its inner side and the mixing tank 2, enhancing the overall structural stability and ensuring the device remains stable during operation. The mixing mechanism 3 is installed inside the mixing tank 2, and its cover plate 31 is made of 8mm thick Q235 steel plate, using multiple... Equally spaced fixing bolts 37 are threaded to the top outer side of the mixing tank 2, forming a detachable sealing structure for easy equipment maintenance and repair. The stirring motor 32 fixed to the top of the cover plate 31 serves as the power source, with its output end connected to the stirring shaft 33, driving the stirring shaft 33 to rotate vertically inside the mixing tank 2. A set of cross-shaped stirring impellers 34 are fixed to the upper and lower outer sides of the stirring shaft 33. These impellers are made of wear-resistant alloy steel, with hardened blade edges to improve wear resistance and stirring efficiency. Impeller grooves 35 are correspondingly provided on the inner side of the mixing tank 2, with the groove width and outer diameter of the cross-shaped stirring impellers 34 in a clearance fit, allowing the outer side of the impeller to slide within the groove. This restricts radial displacement of the impeller while allowing it to rotate around the shaft, preventing collisions between the impeller and the tank wall during stirring. The cast steel support frame 36 fixed at the bottom provides a pivot point for the bottom of the stirring shaft 33, ensuring the stability of the stirring shaft 33 during rotation. When the stirring motor 32 starts, the stirring shaft 33 drives the upper and lower sets of cross-shaped stirring impellers 34 to rotate synchronously. The upper impeller stirs the upper raw materials, and the lower impeller mixes the bottom raw materials. The pressure generated by the rotation of the two sets of impellers is in opposite directions, which promotes the formation of three-dimensional convection in the mixing tank 2. Under the mechanical stirring and convection of the impellers, the raw materials achieve the process from local mixing to overall uniform mixing, ensuring the proportioning accuracy and mixing quality of the raw materials for aerated concrete block production. The material collection box 41 of the discharge mechanism 4 is welded from a 6mm thick Q235 steel plate and fixed to the top of the inner side of the double-layer frame 1. The guide plate 42 on the right side inside is made of 304 stainless steel. The material is inclined at a 10° angle to the horizontal plane, using gravity to guide the stirred raw materials to flow to the left in preparation for discharge. Two hydraulic rods 43 on the right side of the collection box 41 are connected to the double-layer frame 1 via front and rear cast steel fixing blocks 48. The cylinders of the hydraulic rods 43 are embedded in the mounting holes of the fixing blocks 48 and secured with bolts. The push plate 44 fixed to the left end of the piston rod is a composite structure of hard rubber plate and steel plate, with its edge fitting against the inner wall of the collection box 41. It can slide left and right along the box wall under the drive of the hydraulic rods 43. The discharge pipe 45 at the bottom left side of the collection box 41 communicates with the inside of the box. An electromagnetic butterfly valve 47 installed in the middle controls the discharge flow. The telescopic pipe 46 connected to the left end of the discharge pipe 45 is a stainless steel corrugated pipe, which can extend and retract axially to adapt to receiving equipment in different positions, increasing the applicability of the device.The observation window 491 on the front is made of tempered glass and is nested in the collection box 41. The scale line 492 on its left side is etched to monitor the raw material inventory in the box in real time. When the electromagnetic connection valve 7 is opened, the stirred raw material falls from the mixing tank 2 into the collection box 41 and is guided to the left by the guide plate 42. After the electromagnetic butterfly valve 47 is opened, the raw material is discharged through the discharge pipe 45 and the telescopic pipe 46 under the action of gravity. If the raw material has insufficient flowability or accumulates, the hydraulic rod 43 drives the push plate 44 to move to the left, pushing the raw material to the discharge pipe 45 to ensure smooth discharge. The triangular bracing plate 8 on the outside of the mixing tank 2 is made of 5mm thick Q235 steel plate and is in the shape of a right triangle. The top is welded to the outside of the mixing tank 2 and the bottom is fixed to the top outside of the double-layer frame 1. The stability of the triangle is used to distribute part of the load of the mixing tank 2. The stress is transferred to the double-layer frame 1, reducing stress concentration at the connection between the tank and the frame, and effectively limiting the radial sway of the mixing tank 2. The diagonal bracing rods 9 on the inner side of the double-layer frame 1 are Q235 steel pipes with an outer diameter of 30mm and a wall thickness of 3mm. The bottom end is welded to the inner side of the double-layer frame 1, and the top end is fixed equidistantly around the bottom of the mixing tank 2. The diagonal bracing rods 9 and the bottom of the mixing tank 2 form multi-angle support, bearing the vertical force and preventing the mixing tank 2 from shifting up and down. This further disperses the vibration and torque generated during the mixing process. The triangular diagonal bracing plate 8 and the diagonal bracing rods 9 together form a spatial support system. The former mainly deals with the horizontal force, while the latter focuses on the vertical force. The two work together to ensure that the mixing tank 2 remains stable when the mixing motor 32 is running at high speed, avoiding loose connections or component damage caused by vibration, and ensuring the long-term reliable operation of the device.
