Description

Technical Field

[0001] This utility model belongs to the field of geopolymer processing, and specifically relates to a geopolymer mixer. Background Technology

[0002] Geopolymers are environmentally friendly, high-performance, and multifunctional organic compounds. They are environmentally friendly cementitious materials formed by activating silica-alumina-rich solid raw materials with an alkaline solution (i.e., an activating solution), making them one of the ideal alternatives to traditional cement. Their main components are rich in active SiO2 and Al2O3. Common raw materials include industrial byproducts such as fly ash (low or high calcium), slag (high calcium, containing CaO), and silica fume, as well as natural materials such as metakaolin (calcined kaolin) and volcanic ash. Depending on the needs, pre-treated materials such as steel slag and rice husk ash may also be added to the raw materials to enhance their activity. Commonly used alkaline activating solutions are strong alkaline solutions such as NaOH and KOH, or water glass (Na2SiO3). In practice, water glass is often used in combination with NaOH. The geopolymer is obtained by mixing and stirring the raw materials and activating solution evenly.

[0003] Since the alkaline activating solutions used are all strong alkaline solutions with high corrosiveness, the activating solution mixed with the raw materials is prone to splashing out of the mixing chamber during the stirring and mixing process, which poses a certain danger. In addition, the amount of activating solution used is relatively small compared with the amount of raw materials used. Directly adding the activating solution to the raw materials and then stirring and mixing can easily lead to small-scale agglomeration, which is not conducive to the full mixing of the various components. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a geopolymer mixer to solve the problems of using alkaline activating liquids, which are all strong alkaline solutions with high corrosiveness. During the mixing process of the above materials, the activating liquid mixed with the raw materials is prone to splashing out of the mixing chamber, which poses a certain danger. In addition, the amount of activating liquid used is relatively small compared with the amount of raw materials used. Directly adding the activating liquid to the raw materials and then mixing them can easily lead to small-scale agglomeration, which is not conducive to the full mixing of the various components.

[0005] According to the embodiments of this utility model, the following technical solution is adopted:

[0006] Geopolymer mixer includes a mixing chamber, a mixing assembly for mixing within the mixing chamber, a batching assembly for adding an activating liquid into the mixing chamber, and a protective assembly for protecting the upper part of the mixing chamber. The protective assembly includes a protective plate movably connected to the top or side wall of the mixing chamber. Multiple protective plates are provided and distributed circumferentially around the mixing chamber. The protective plates have a protective state where they block the upper part of the mixing chamber and an idle state where they are offset from the upper part of the mixing chamber. The batching assembly includes a storage chamber and multiple conveying pipes connected between the storage chamber and each protective plate. The storage chamber is used to store the activating liquid. The protective plates have through holes communicating with the conveying pipes. Connecting pipes are detachably connected to the through holes. Several spray holes are provided on the connecting pipes. Spray heads are detachably connected to the spray holes.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1. Solid raw materials are placed in the mixing chamber, while the activating liquid is stored in the storage chamber. During the mixing process, the activating liquid is introduced through the delivery pipe, connecting pipe, and nozzle. The nozzle is installed on the protective plate and located above the mixing chamber. It is sprayed in during the mixing process of the raw materials, and the mixing is completed along with the mixing components during the spraying process, which reduces agglomeration to a certain extent and improves the uniformity of mixing.

[0009] 2. The protective plate is movably connected to the mixing chamber. When materials are fed into the mixing chamber, the protective plate is in an idle state, which will not affect the staff's feeding. During the mixing process, the protective plate is in a protective state, reducing the danger caused by material splashing.

[0010] Furthermore, the stirring assembly includes a mounting frame that slides vertically, a stirring shaft that is rotatably mounted on the mounting frame, and stirring blades mounted on the stirring shaft.

[0011] Furthermore, a planetary gear system is installed on the mounting frame. The planetary gear system includes a sun gear rotatably connected to the mounting frame, a planet carrier rotatably connected to the mounting frame, planet gears rotatably connected to the planet carrier, and an internal gear ring fixedly connected to the mounting frame. The sun gear, planet gears, and internal gear ring mesh in sequence. The stirring shaft is coaxially fixed on the planet gears.

[0012] Furthermore, the protective plate is detachably connected to the side wall of the mixing chamber.

[0013] Furthermore, the protective plate is hinged to the top side wall of the mixing chamber.

[0014] Furthermore, the protective plate is vertically slidably connected to the side wall of the mixing chamber.

[0015] Furthermore, temperature sensors are installed in both the storage and mixing chambers.

[0016] Furthermore, the mixing chamber is equipped with isolation measures around its perimeter to prevent personnel from approaching.

[0017] Furthermore, the isolation components include virtual barriers set along the circumference of the mixing chamber.

[0018] Furthermore, the isolation components include baffles with openings that can close the entrances and exits. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments will be given.

[0026] like Figure 1 As shown, the geopolymer mixer includes a mixing chamber 1, a mixing assembly for mixing within the mixing chamber 1, a batching assembly for adding an activating liquid into the mixing chamber 1, and a protective assembly for protecting the upper part of the mixing chamber 1.

[0027] The mixing assembly includes a vertically sliding mounting frame 7, a rotatable mixing shaft 6 mounted on the mounting frame 7, and mixing blades 5 mounted on the mixing shaft 6. In this embodiment, the vertical sliding of the mounting frame 7 allows it to drive the mixing blades 5 into or out of the mixing chamber 1, and adjusts the depth of the mixing blades 5 within the mixing chamber 1. In practical design, the mounting frame 7 can be installed using a frame, such as... Figure 1 As shown, the frame is provided with a slide groove 8 for the mounting bracket 7 to slide, and the mounting bracket 7 can be driven to slide by conventional driving methods of the prior art (such as cylinders).

[0028] In this embodiment, the stirring shaft 6 is directly rotatably connected to the mounting frame 7, and the stirring blades 5 are fixed to the stirring shaft 6. The shape and number of the stirring blades 5 can be designed according to actual needs. A motor for driving the stirring shaft 6 to rotate is installed on the mounting frame 7. In actual design, the stirring shaft 6, stirring blades 5, and inner wall of the stirring chamber 1 can all be designed with existing anti-corrosion coatings according to actual usage to improve service life. After the stirring blades 5 leave the stirring chamber 1 with the mounting frame 7, they are also easy to clean or maintain.

[0029] The protective assembly includes a protective plate 4 movably connected to the top or side wall of the mixing chamber 1. Multiple protective plates 4 are provided and distributed around the circumference of the mixing chamber 1. The protective plates 4 have a protective state that blocks the upper part of the mixing chamber 1 and an idle state that is away from the upper part of the mixing chamber 1. When materials are put into the mixing chamber 1, the protective plates 4 are in the idle state to avoid the protective plates 4 affecting the staff's feeding of materials. During the mixing process, the protective plates 4 are in the protective state, blocking the mixing chamber 1 to a certain extent and reducing the danger caused by material splashing.

[0030] The following are three specific design methods for the protective plate 4. In the actual design process, you can choose according to your needs, as follows:

[0031] A. The protective plate 4 is detachably connected to the top of the mixing chamber 1, such as Figure 1 As shown, two protective plates 4 are provided, which are snapped onto the top of the mixing chamber 1. A gap is left between the two protective plates 4 to allow the mixing shaft 6 to pass through, so as not to affect the rotation and mixing of the mixing shaft 6. In actual design, the gap between the two protective plates 4 is slightly larger than the width of the mounting bracket 7, combined with... Figure 5 As shown, the free end of the mounting frame 7 can also be placed on the top of the mixing chamber 1. Then, after the mixing shaft 6 enters the mixing chamber 1, the protective plate 4 can be installed, so that the mounting frame 7 can also serve as a protective part of the top of the mixing chamber 1, further sealing the top of the mixing chamber 1.

[0032] B. The protective plate 4 is hinged to the side wall of the mixing chamber 1. The difference from design method A is that the protective plate 4 is connected to the mixing chamber 1 by a hinge. Therefore, when the protective plate 4 is opened, the protective plate 4 is still connected to the mixing chamber 1, and there is no need to find a place to put it.

[0033] C. For example Figure 3 As shown, the protective plate 4 is vertically slidably connected to the side wall of the mixing chamber 1. By sliding the protective plate 4 upwards, the height of the mixing chamber 1 is increased, thus creating a vertical enclosure. Splashed materials will also splash onto the inner wall of the protective plate 4. The protective plate 4 is also equipped with two ( Figure 3Only the protective plate 4 on the rear side of the diagram is shown. A gap is left between the two protective plates 4 for the stirring shaft 6 and the mounting bracket 7 to pass through. In this embodiment, the protective plate 4 is driven to slide vertically by a cylinder in the prior art. In actual design, other methods can also be used to drive the protective plate 4 to slide.

[0034] like Figure 2 , Figure 3 As shown, the mixing assembly includes a storage chamber 2 and multiple delivery pipes 3 connected between the storage chamber 2 and each protective plate 4. The storage chamber 2 stores the activating liquid. The protective plate 4 has a through hole communicating with the delivery pipes 3. A connecting pipe 9 is detachably connected to the through hole. Specifically, during assembly, a threaded pipe is connected to the middle of the connecting pipe 9, and the threaded pipe is threaded into the through hole. The axis of the connecting pipe 9 is perpendicular to the axis of the threaded pipe. Several spray holes are formed along the axial direction of the connecting pipe 9. A nozzle 10 is detachably connected to each spray hole. Specifically, the nozzle 10 is also connected to a threaded pipe, which is threaded into the spray hole. Through the design of the connecting pipe 9, multiple nozzles 10 can be connected simultaneously, increasing the spray range. Figure 2 As shown, in either design A or design B of the above-mentioned protective plate 4, the connecting pipe 9 can be installed in the middle of the protective plate 4, so that the sprayed activating liquid can also be sprayed into the middle of the mixing chamber 1, thereby improving the uniformity of mixing.

[0035] In another embodiment of this utility model, a different design for the stirring assembly is provided, as follows: Figure 4 As shown, a planetary gear train is mounted on the mounting frame 7. The planetary gear train includes a sun gear 11 rotatably connected to the mounting frame 7, a planet carrier 14 rotatably connected to the mounting frame 7, planet gears 12 rotatably connected to the planet carrier 14, and an internal gear ring 13 fixedly connected to the mounting frame 7. The sun gear 11, planet gears 12, and internal gear ring 13 mesh sequentially from the inside to the outside. In this embodiment, the planetary gear train uses the sun gear 11 as the driving member, the internal gear ring 13 as the fixed member, and the planet carrier 14 as the driven member. The sun gear 11 is driven to rotate by a conventional driving method in the prior art (such as a motor), which in turn drives the planet carrier 14 to revolve. The planet gears 12 also rotate on their own axis as the planet carrier 14 revolves.

[0036] The stirring shaft 6 is coaxially fixed on the planetary gear 12, and the stirring blade 5 is fixed on the stirring shaft 6. This design allows the stirring blade 5 to rotate on its own axis while revolving around the sun, thereby increasing the shearing force and achieving a better stirring effect.

[0037] In another embodiment of this utility model, temperature sensors are installed in both the storage chamber 2 and the stirring chamber 1. The temperature of the activating liquid and the temperature during the stirring process are usually 20-40°C. The temperature sensors monitor the temperature in the storage chamber 2 and the stirring chamber 1. When the temperature is too low or too high, the staff can intervene.

[0038] In another embodiment of this utility model, in order to further improve operational safety, the mixing chamber 1 is equipped with isolation components around its perimeter to prevent personnel from approaching. This embodiment provides two design methods for the isolation components, which can be selected according to actual needs, as follows:

[0039] a. The isolation components include a virtual enclosure set around the circumference of the mixing chamber 1. Specifically, a ring-shaped light strip is installed on the mounting frame 7. After being powered on, it can illuminate the ring-shaped area on the ground around the mixing chamber 1 to remind staff not to approach.

[0040] b. The isolation component includes a baffle 15 with an entrance and exit that can be closed. Specifically, the baffle 15 is placed around the mixing chamber 1 to physically prevent personnel from accidentally approaching. The position of the baffle 15 can be moved to leave or close the entrance and exit for personnel to enter and exit. Alternatively, a door frame can be opened on the baffle 15 and a door can be installed to allow personnel to enter and exit.
