Description

Technical Field

[0001] This utility model relates to the field of block production technology, specifically to an aerated block raw material mixing and batching device. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a type of porous building material that is lightweight, high-strength, heat-insulating, heat-resistant, flame-retardant, low-carbon, environmentally friendly, sound-absorbing, sound-insulating, impermeable, and earthquake-resistant. With its excellent properties, it is widely used in the construction industry. The main raw materials for AAC blocks are lime and cement, but river sand, fly ash, mineral sand, industrial waste, slag, and construction waste can also be used, enabling waste recycling. The product has the advantages of energy conservation and environmental protection. In the production of AAC blocks, various powdered raw materials are added to a mixing tank in proportion, and then water is added to the mixing tank for mixing and stirring. After mixing, the blocks undergo blanking, cutting, and autoclaving processes to finally obtain the finished AAC blocks.

Since an excessively large agitator cannot be used, which would occupy too much space inside the mixing tank, the actual area that the spiral blade can mix and roll the raw materials is limited. On the other hand, simply increasing the number of spiral blades would result in gaps between the spiral blades, affecting the fullness of the mixing.

[0005] A mixing and batching device for aerated concrete block raw materials is proposed to solve the problems mentioned above. Utility Model Content

[0010] Preferably, the output shaft of the first motor passes through the middle of the hollow cylinder and is fixedly connected to the middle of the sun gear. The driven gear is distributed around the circumference of the sun gear and meshes with the sun gear. The driven gear is also meshed with the ring gear.

[0015] Preferably, a water guide pipe is fixedly installed on one side of the top of the tank lid, a flow meter is fixedly installed on the outside of the water guide pipe, and a hanging lug is symmetrically and fixedly connected to the top surface of the mixing tank.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This aerated concrete block raw material mixing and batching device integrates efficient three-dimensional stirring and intelligent wall-cleaning functions with obstruction retraction, completely solving the industry problems of uneven mixing and easy jamming and shutdown in traditional batching tanks. Its specific contents are as follows:

[0017] 1. First, this device achieves compound motion with high mixing efficiency. It cleverly utilizes a planetary gear mechanism, where the central sun gear drives multiple driven gears, allowing the torsion bar to simultaneously revolve around the center of the tank and rotate rapidly on its own axis. The revolution ensures overall macroscopic circulation, preventing localized solidification, while the rotation generates strong localized shearing and eddies, breaking up clumps. This compound motion of revolution and rotation, combined with the vertical lifting effect of its curved shape on the material, achieves a perfect combination of diffusion, shearing, and convection mixing mechanisms, greatly improving mixing uniformity and speed. Second, the entire transmission system is integrated within a hollow hood and isolated from the mixing area by a partition plate, effectively preventing dust intrusion and ensuring transmission stability and lifespan. Furthermore, the system integrates planetary mixing with the bottom scraper function. Driven by the revolution, the triangular scraper at the bottom rotates synchronously, continuously cleaning and conveying heavy materials that easily deposit at the bottom of the tank. This complements the function of the upper torsion bar, ensuring comprehensive, dead-angle-free mixing from the tank wall to the bottom.

[0018] 2. Firstly, the wall-cleaning component achieves dynamic adaptive wall cleaning. Under the constant initial pressure provided by the pneumatic rod, the inclined scraper can always rotate in close contact with the tank wall, effectively scraping away the deposits and keeping the tank wall clean. Secondly, this device has an effective overload avoidance function, preventing jamming and damage. When the inclined scraper encounters an exceptionally hard deposit, the radial resistance it experiences increases sharply. At this time, this resistance overcomes the damping force and output force of the pneumatic rod, pushing the entire actuator, composed of the mounting shaft and slider, to retract radially towards the center along the groove inside the scraper plate, thus achieving "temporary avoidance." This process avoids the risk of jamming, shutdown, or even motor burnout or component damage caused by forced scraping, greatly improving the reliability and automation of the equipment. Finally, its structural design considers protection under harsh working conditions. The isolation bellows cover completely encloses the core drive air rod, effectively isolating it from dust and moisture generated during the mixing process. This ensures the sensitivity and service life of the pneumatic components, enabling the assembly to work stably in environments with high dust levels and a tendency to clump together, such as aerated concrete raw materials.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figures 1-6 The present invention provides a technical solution: an aerated concrete block raw material mixing and batching device, including a batching tank 1, a tank cover 101 is snapped on the top of the batching tank 1, and a feeding channel 102 is fixedly installed on one side of the top surface of the tank cover 101; the material is fed through the feeding channel 102; and a discharge valve pipe is installed on one side of the bottom of the batching tank 1.

[0028] A stirring assembly 2 is provided in the middle of the tank cover 101. The stirring assembly 2 includes a hollow cover 201. A first motor 202 is fixedly connected to the top surface of the hollow cover 201. An isolation plate 203 is rotatably connected to the middle of the middle of the middle of the bottom surface of the isolation plate 203. A drive rod 204 is fixedly connected to the middle of the inner top surface of the first motor 202. A hollow cylinder 205 is rotatably connected to the outer side of the hollow cylinder 205. A driven gear 208 is rotatably connected to the bottom surface of one end of the suspension arm 206. A rotating shaft 211 is fixedly connected to the bottom surface of the driven gear 208. A sun gear 209 is rotatably connected to the bottom end of the hollow cylinder 205. A shovel plate 213 is fixedly connected to the bottom of the drive rod 204. A torsion rod 212 is fixedly connected to the bottom surface of the rotating shaft 211. A gear ring 210 is fixedly connected to the inner side of the hollow cover 201. After feeding, the stirring assembly starts. The first motor 202 is activated, causing the sun gear 209 to rotate. Through meshing transmission, the driven gear 208, in conjunction with the gear ring 210, rotates on its own axis while revolving around the sun gear 209. As the driven gear 208 revolves, the suspension arm 206 and the hollow cylinder 205 rotate together. This causes the rotating shaft 211 to drive the torsion bar 212 to rotate, and the plurality of rotating shafts 211 and torsion bars 212 move around the drive rod 204, thoroughly mixing the raw materials in the mixing tank 1. Furthermore, due to the curved shape of the torsion bar 212, the raw materials are guided upwards, causing them to tumble vertically. The hollow cover 201 is fixed to the top surface of the mixing tank 1. The suspension component, consisting of the hollow cylinder 205 and the suspension arm 206, suspends the driven gear 208. As the drive rod 204 revolves with the driven gear 208, the isolation plate 203 rotates accordingly.

[0029] The output shaft of the first motor 202 passes through the middle of the hollow cylinder 205 and is fixedly connected to the middle of the sun gear 209. The driven gear 208 is distributed around the circumference of the sun gear 209 and meshes with the sun gear 209. The driven gear 208 also meshes with the gear ring 210. As the drive rod 204 rotates.

[0030] The top of the rotating shaft 211 passes through the isolation plate 203 and is connected to the isolation plate 203 through a bearing; the isolation plate 203 can isolate the stirring space inside the mixing tank 1 and the gear components inside the hollow cover 201, so as to prevent flying dust from interfering with the gear transmission.

[0031] The spatula 213 is a right-angled triangular prism, and the bottom surface of the spatula 213 is in contact with the inner bottom surface of the mixing tank 1. The spatula 213 will scoop up the raw materials inside the mixing tank 1, and the raw materials will be guided upward by the inclined surface of the spatula 213, which will promote stirring.

[0032] A wall-cleaning assembly 3 is provided on the outer side of the isolation plate 203. The wall-cleaning assembly 3 includes an extension rod 301. A clearance groove 302 is formed in the middle of the extension rod 301. An air rod 303 is fixedly installed inside the clearance groove 302. An isolation bellows cover 308 is symmetrically covered on the outside of the clearance groove 302. A sliding groove 304 is formed inside the shovel plate 213. A slider 305 is slidably connected inside the sliding groove 304. A mounting shaft 306 is fixedly connected in the middle of the slider 305. The top end of the mounting shaft 306 is connected through the isolation bellows cover 308. The extension and retraction force of the air rod 303 will cause... The inclined scraper 307 fits against the inner wall of the mixing tank 1. When the inclined scraper 307 rotates and contacts the raw material block that is attached to the inner wall of the mixing tank 1, the inclined surface of the inclined scraper 307 will cause the mounting shaft 306 to slide in the relief groove 302 due to compression, so as to achieve temporary relief and avoid rotation jamming. The isolation bellows cover 308 can prevent dust from interfering with the extension and retraction of the air rod 303. The clearance fit between the slider 305 and the slide groove 304 makes the mounting shaft 306 slide only along the radial direction of the shovel plate 213 without unnecessary shaking or twisting. The air rod 303 is a miniature damping cylinder.

[0033] One side of the air rod 303 is fixedly connected to the inner wall of the clearance groove 302, and the output end of the air rod 303 is fixedly connected to the top of the mounting shaft 306. An inclined scraper 307 is fixedly connected to the outer side of the mounting shaft 306, and the inclined scraper 307 is in contact with the inner wall of the mixing tank 1. The air rod 303 provides the initial wall-adhering pressure. When the scraper encounters excessive resistance, the external force will overcome the damping force and thrust of the air rod 303, and push the entire mounting shaft 306 and slider 305 assembly to retract towards the center to achieve clearance.

[0034] A water guide pipe 5 is fixedly installed on one side of the top of the tank lid 101. A flow meter 501 is fixedly installed on the outside of the water guide pipe 5. A hanging ear 4 is symmetrically fixedly connected to the top surface of the mixing tank 1. The water guide pipe 5 is connected to an external water pump. When water is injected, the flow meter 501 can accurately measure the injection volume. The hanging ear 4 makes it convenient to use an external lifting tool to lift the mixing tank 1 and manually clean the stirring assembly 2 and the inner wall of the mixing tank 1.

[0035] Working principle: Before using this type of aerated concrete block raw material mixing and batching device, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 6 As shown, after the raw materials are fed into the batching tank 1 through the feeding channel 102, the first motor 202 is started;

[0036] The first motor 202 drives the sun gear 209 to rotate, and transmits power to the hollow cylinder 205 through a planetary gear system consisting of the sun gear 209, the driven gear 208, and the fixed gear ring 210. This transmission process causes the driven gear 208 to rotate on its own axis while also revolving around the sun gear 209. The revolution causes the hollow cylinder 205 and the fixed suspension arm 206, drive rod 204, and shovel plate 213 to rotate together; while the rotation is driven by the rotating shaft 211 to drive the torsion bar 212 at its bottom to rotate at high speed. Thus, the multiple torsion bars 212 rotate at high speed while revolving around the center of the tank, generating strong shearing, diffusion, and convection effects on the material. Their unique curved shape can effectively guide the material to tumble in the vertical direction.

[0037] At the same time, the triangular shovel 213, which rotates synchronously with the drive rod 204, continuously scoops up and pushes the material at the bottom of the tank upward to prevent sedimentation.

[0038] Furthermore, under the continuous pressure of the air rod 303, the wall cleaning component 3 causes the inclined scraper 307 to rotate tightly against the tank wall, removing the adhering raw materials. When encountering particularly large clumps, its unique damping and sliding avoidance mechanism effectively prevents the equipment from jamming. Process water can be accurately injected and metered through the water pipe 5 and the flow meter 501. Ultimately, the synergistic effect of the above-mentioned multiple stirring and cleaning actions achieves all-round, high-efficiency, and dead-angle-free mixing of materials in both horizontal and vertical directions.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
