Technical Field
[0001] This utility model relates to the field of geopolymer mortar processing technology, specifically a geopolymer mortar production and preparation device. Background Technology
[0002] The carbon emissions generated during the preparation of 1 kg of geopolymer cement are only 0.18 kg, which is only 24% of that of ordinary Portland cement. Furthermore, the energy consumption required for its production is significantly lower, only 30% of that required for cement production. If the activity of solid waste is further improved, its energy consumption can be reduced to 10% of that required for cement production. The concept of geopolymers was proposed by French scholar Davidovits in 1978. Geopolymers are inorganic polymers with a three-dimensional network structure composed of [AlO3] and [SiO4] tetrahedral structural units, with the chemical formula Mn{(SiO2)2AlO2}·wH2O. They are non-metallic materials ranging from amorphous to semi-crystalline. Geopolymers possess excellent mechanical properties, fire resistance, high-temperature resistance, corrosion resistance, and good impermeability, making them highly favored by researchers and considered a potential substitute for cement or a supplement to cement materials in certain fields.
[0003] Geopolymers are novel cementitious materials with a zeolite-like structure, formed by the curing of silica-alumina-based additives and activators through a "dissolution-unit rearrangement-condensation" reaction process at room temperature or under specific curing conditions. Numerous studies have shown that the performance of geopolymers is affected by various factors, including the stirring mechanism. The preparation of geopolymer mortar requires a preparation device to mix various additives and alkaline activators. However, existing preparation devices, when mixing the additives, rely solely on a stirring rod, which fails to adequately mix the additives evenly, resulting in poor mixing and consequently affecting the mortar's performance. To address these issues, the inventors propose a geopolymer mortar production and preparation device. Utility Model Content
[0004] To address the problem that mixing multiple auxiliary materials in geopolymer mortar using only a stirring rod cannot achieve sufficient and uniform mixing, resulting in poor mixing effect, the purpose of this invention is to provide a geopolymer mortar production and preparation device.
[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a geopolymer mortar production and preparation device, including a support frame, a slider slidably disposed within the support frame, connecting rods fixedly disposed on opposite sides of the slider, a mixing tank fixedly connected between the connecting rods, a first inclined block fixedly disposed on the bottom surface of the slider, a U-shaped frame slidably disposed within the support frame, a second inclined block fixedly disposed on the top surface of the U-shaped frame, a fixed plate fixedly disposed within the U-shaped frame, a toothed plate fixedly disposed within the fixed plate, a first motor mounted on one side of the support frame, a half-face gear fixedly disposed at the output end of the first motor, the half-face gear meshing with the toothed plate, a groove opened within the fixed plate, and two sets of toothed plates arranged opposite each other within the groove. First, auxiliary materials are fed into the mixing tank from the feed hopper on the mixing tank, and then... The second motor is started, causing the shaft to rotate, which in turn causes the stirring blades to mix the various auxiliary materials of the geopolymer slurry. Then the first motor is started, causing the half-face gear to rotate. When the half-face gear meshes with one set of toothed plates, it causes the fixed plate to slide the U-shaped frame within the support frame, and causes the second inclined block to move closer to the first inclined block. The inclined surfaces of the second and first inclined blocks then engage with each other, causing the slider to move the connecting rod upward and simultaneously raising the mixing tank. Then, when the half-face gear meshes with another set of toothed plates, it causes the U-shaped frame to move the second inclined block away from the first inclined block, and separates the inclined surfaces of the second and first inclined blocks. This causes the slider to move the connecting rod downward, lowering the mixing tank. This allows the mixing tank to move up and down repeatedly, agitating the various auxiliary materials within the mixing tank and ensuring thorough and uniform mixing.
[0006] After mixing, the solenoid valve is opened, allowing the mixed auxiliary materials to be discharged from the discharge pipe. Then, the third motor is turned on, causing the rotating rod to rotate. The rotating rod drives the worm gear to rotate, and the worm gear meshes with the worm wheel, which in turn drives the threaded rod to rotate within the fixed frame. This causes the threaded plate to drive the positioning rod to insert into the mixing barrel, which in turn causes the limiting ring and scraper to slide within the mixing barrel. During the discharge process, the scraper can scrape off the auxiliary materials adhering to the inner wall of the mixing barrel, avoiding waste of auxiliary materials.
[0007] Preferably, a positioning rod is slidably inserted into the mixing tank, a limiting ring is fixedly provided at the bottom end of the positioning rod, a scraper is fixedly provided on the outer surface of the limiting ring, the scraper is attached to the inner wall of the mixing tank, a fixing frame is fixedly provided on the top surface of the mixing tank, a threaded plate is slidably provided in the fixing frame, the positioning rod is fixedly provided on the bottom surface of the threaded plate, a threaded rod is rotatably provided in the fixing frame, the threaded plate is threadedly sleeved on the outer surface of the threaded rod, a positioning plate is fixedly provided on the top surface of the fixing frame, a third motor is installed on one side of the positioning plate, a rotating rod is fixedly provided at the output end of the third motor, a worm is fixedly sleeved on the outer surface of the rotating rod, a worm wheel is fixedly sleeved on the outer surface of the threaded rod, and the worm and the worm wheel mesh with each other.
[0008] Preferably, a second motor is installed on the top surface of the mixing tank, a rotating shaft is fixedly provided at the output end of the second motor, a stirring blade is fixedly provided on the outer surface of the rotating shaft, a discharge pipe is fixedly provided on the bottom surface of the mixing tank, and a solenoid valve is installed on the outer surface of the discharge pipe.

[0010] 1. In this utility model, by moving the mixing bucket up and down repeatedly, the various auxiliary materials inside the mixing bucket can be turned over, so that the auxiliary materials can be fully and evenly mixed during the mixing process, resulting in a good mixing effect and improving the performance of the mortar.
[0011] 2. In this utility model, the positioning rod is inserted into the mixing barrel, thereby driving the limiting ring and scraper to slide inside the mixing barrel. During the discharge process, the scraper can scrape off the auxiliary materials adhering to the inner wall of the mixing barrel, thus avoiding waste of auxiliary materials.

[0021] 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.
[0022] Example: Figure 1-7As shown, this utility model provides a geopolymer mortar production and preparation device, including a support frame 1, a slider 11 slidably disposed within the support frame 1, connecting rods 12 fixedly disposed on opposite sides of the slider 11, a mixing tank 2 fixedly connected between the connecting rods 12, a first inclined block 13 fixedly disposed on the bottom surface of the slider 11, a U-shaped frame 14 slidably disposed within the support frame 1, a second inclined block 15 fixedly disposed on the top surface of the U-shaped frame 14, a fixing plate 16 fixedly disposed within the U-shaped frame 14, a toothed plate 17 fixedly disposed within the fixing plate 16, a first motor 18 mounted on one side of the support frame 1, a half-face gear 19 fixedly disposed at the output end of the first motor 18, the half-face gear 19 meshing with the toothed plate 17, a groove 161 formed within the fixing plate 16, and two sets of toothed plates 17 arranged opposite each other within the groove 161. During mixing, by turning on the first motor 18, the half-face gear 19 is mixed with the toothed plate 17. When the face gear 19 rotates, and the half-face gear 19 meshes with one of the sets of toothed plates 17, it causes the fixed plate 16 to drive the U-shaped frame 14 to slide within the support frame 1, and causes the second inclined block 15 to move closer to the first inclined block 13, so that the inclined surface of the second inclined block 15 and the inclined surface of the first inclined block 13 cooperate with each other, causing the slider 11 to drive the connecting rod 12 to move upward, and at the same time, causing the mixing barrel 2 to rise. Then, when the half-face gear 19 meshes with another set of toothed plates 17, it causes the U-shaped frame 14 to drive the second inclined block 15 away from the first inclined block 13, and causes the inclined surface of the second inclined block 15 to separate from the inclined surface of the first inclined block 13, so that the slider 11 drives the connecting rod 12 to move downward, and the mixing barrel 2 descends, so that the mixing barrel 2 can move up and down repeatedly, so that the various auxiliary materials in the mixing barrel 2 can be turned over, and thus the auxiliary materials can be thoroughly and evenly mixed, resulting in a good mixing effect and improved mortar performance.
[0023] A positioning rod 38 is slidably inserted inside the mixing tank 2. A limiting ring 39 is fixedly installed at the bottom end of the positioning rod 38. A scraper 391 is fixedly installed on the outer surface of the limiting ring 39. The scraper 391 is attached to the inner wall of the mixing tank 2. A fixing frame 3 is fixedly installed on the top surface of the mixing tank 2. A threaded plate 37 is slidably installed inside the fixing frame 3. The positioning rod 38 is fixedly installed on the bottom surface of the threaded plate 37. A threaded rod 35 is rotatably installed inside the fixing frame 3. The threaded plate 37 is threadedly sleeved on the outer surface of the threaded rod 35. A positioning plate 31 is fixedly installed on the top surface of the fixing frame 3. A third motor 32 is installed on one side of the positioning plate 31. A rotating rod 33 is fixedly installed at the output end of the third motor 32. A worm gear 34 is fixedly sleeved on the outer surface of the rotating rod 33. A worm wheel 36 is fixedly sleeved on the outer surface of the threaded rod 35. The worm gear 34 and the worm wheel 36 mesh with each other.
[0024] By adopting the above technical solution, the third motor 32 is turned on, causing the rotating rod 33 to rotate. The rotating rod 33 drives the worm 34 to rotate, and the worm 34 meshes with the worm wheel 36, thereby driving the threaded rod 35 to rotate within the fixed frame 3. This causes the threaded plate 37 to drive the positioning rod 38 to insert into the mixing tank 2, thereby causing the limiting ring 39 and the scraper 391 to slide within the mixing tank 2. During the discharge process, the scraper 391 can scrape off the auxiliary materials adhering to the inner wall of the mixing tank 2, avoiding waste of auxiliary materials.
[0025] A second motor 21 is installed on the top surface of the mixing tank 2. A rotating shaft 22 is fixedly installed at the output end of the second motor 21. A stirring blade 23 is fixedly installed on the outer surface of the rotating shaft 22. A discharge pipe 24 is fixedly installed on the bottom surface of the mixing tank 2. A solenoid valve 25 is installed on the outer surface of the discharge pipe 24. A mortar preparation device 4 is installed below the support frame 1. A mortar mixer 41 is installed on one side of the mortar preparation device 4.
[0026] By adopting the above technical solution, the second motor 21 is turned on, causing the rotating shaft 22 to rotate, thereby causing the stirring blades 23 to mix various auxiliary materials of the geopolymer slurry. The support frame 1 and the mortar preparation device 4 are fixedly connected by bolts. After the various auxiliary materials are mixed, the solenoid valve 25 is turned on, so that the mixed auxiliary materials are discharged from the discharge pipe 24 into the mortar preparation device 4. Then, raw materials are added into the mortar preparation device 4, and then the mortar agitator 41 is turned on to stir, so that the raw materials and auxiliary materials can be mixed, thereby preparing the geopolymer mortar.
[0027] Working principle: First, the auxiliary materials are fed into the mixing tank 2 from the feed hopper. The second motor 21 is turned on, causing the rotating shaft 22 to rotate, which in turn causes the stirring blades 23 to mix the various auxiliary materials of the geopolymer slurry. Then, the first motor 18 is turned on, causing the half-face gear 19 to rotate. When the half-face gear 19 meshes with one set of toothed plates 17, it causes the fixed plate 16 to slide the U-shaped frame 14 within the support frame 1, and also causes the second inclined block 15 to approach the first inclined block 13, so that the inclined surface of the second inclined block 15 is aligned with the first inclined block 13. The inclined surfaces work together to cause the slider 11 to move the connecting rod 12 upward, which in turn causes the mixing barrel 2 to rise. Then, when the half-face gear 19 meshes with another set of toothed plates 17, the U-shaped frame 14 causes the second inclined block 15 to move away from the first inclined block 13, and the inclined surface of the second inclined block 15 to separate from the inclined surface of the first inclined block 13. This causes the slider 11 to move the connecting rod 12 downward, which in turn causes the mixing barrel 2 to descend. This allows the mixing barrel 2 to move up and down repeatedly, which allows the various auxiliary materials in the mixing barrel 2 to be turned over, and thus the auxiliary materials to be thoroughly and evenly mixed.
[0028] After mixing, the solenoid valve 25 is opened, allowing the mixed auxiliary materials to be discharged from the discharge pipe 24 into the mortar preparation device 4. Then, raw materials are added into the mortar preparation device 4, and the mortar mixer 41 is turned on to mix the raw materials and auxiliary materials, thereby preparing geopolymer mortar. Then, the third motor 32 is turned on, causing the rotating rod 33 to rotate. The rotating rod 33 drives the worm 34 to rotate, and the worm 34 meshes with the worm wheel 36, thereby driving the threaded rod 35 to rotate in the fixed frame 3. This causes the threaded plate 37 to drive the positioning rod 38 to be inserted into the mixing tank 2, thereby causing the limiting ring 39 and the scraper 391 to slide in the mixing tank 2. During the discharge process, the scraper 391 can scrape off the auxiliary materials adhering to the inner wall of the mixing tank 2, avoiding waste of auxiliary materials.
[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
