The Chinese invention patent with publication number CN103821247A discloses a glass magnesium fireproof board and a production method. Magnesium chloride is first made into an aqueous solution, and the amount of water added to the aqueous solution is based on the ability to wet all mixed raw materials and fully stir them. The magnesium chloride aqueous solution is then mixed and stirred with magnesium oxide, filler, modifying additive and retarder to form a paste-like mixture, and then the mixture is placed in a mold of a plate making machine, and glass solder cloth is placed on the upper and lower parts of the mold respectively, so that the mixture is placed between the upper and lower glass solder cloths to form. It has the characteristics of less material composition, simple production process, and can improve the product cost performance under the premise of meeting the fireproof quality requirements.

However, there are certain defects in the mixing process of the glass magnesium flat panel raw materials. For example, when mixing the raw materials, the existing mixing process of the glass magnesium flat panel raw materials generally adopts the method of placing all the materials together for stirring and mixing. Due to the large number of raw materials, during the mixing process, not only is the mixing difficulty greater, which increases the operating load of the mixing equipment, but also affects the full contact between the raw materials, thereby reducing the quality of the glass magnesium flat panel slurry and the subsequent solidified glass magnesium flat panel.

[0044] S3, remixing of raw materials: adding the remaining wollastonite powder and lightweight filler to the mixing equipment for mixing, and simultaneously injecting the remaining water into the mixing equipment at 3-8 L / min, adding the foaming agent into the mixing equipment on the way, mixing the raw materials in a surging manner until all the water is replenished and the mixing is stopped to form a foaming slurry;

[0045] S4, slurry leading out and molding: select a template with no surface defects, apply a release agent on the template, then lay glass fiber cloth, pour the foaming slurry prepared in S3 onto the glass fiber cloth by mixing and stirring and surging, and flatten the liquid surface of the slurry, then let it stand until the above mixture solidifies, and then demold;

[0046] The reinforcing agent composed of illite clay, lightweight filler and wollastonite powder can increase the strength of the glass magnesium middle board, thereby making the composite glass magnesium floor have higher strength, expanding the application range of the glass magnesium middle board and effectively reducing the warping of the board;

[0047] By adding the raw materials one by one to mix them, not only the difficulty of the mixing process and the operating intensity of the mixing equipment are reduced, but also the full contact between the raw materials is improved, further improving the water resistance and long-term use performance of the glass magnesium intermediate board and the product cost performance.

[0048] S1 includes the following components by weight: 65 parts of magnesium oxide, 30 parts of anhydrous magnesium chloride; 10 parts of illite clay, 10 parts of wollastonite powder, 43 parts of lightweight filler, 3 parts of foaming agent, and 80 parts of water.

[0049] The lightweight filler in S1 includes one or more of sawdust, vitrified microspheres, polystyrene particles, straw, vermiculite and ceramsite.

[0050] See attached Figures 2 to 8 The mixing device comprises a tank body 1 with a conical bottom, a feed pipe 2 is arranged on the top of the outer surface of the tank body 1, and a water injection pipe is connected to the feed pipe 2, and a discharge pipe 3 is connected to the bottom of the tank body 1;

[0051] The feed pipe 2 is used to discharge the raw materials required for the plate into the tank body 1, the water injection pipe is used to inject the water source required for mixing into the tank body 1, and the discharge pipe 3 is used to discharge the mixed slurry;

[0052] A mixing assembly 4 is provided inside the tank body 1, and the mixing assembly 4 includes a mixing element 41 for mixing and stirring the raw materials, a processing element 42 for stirring the raw materials accumulated at the bottom of the tank body 1, and a scraper element 43 for cleaning the inner surface of the tank body 1;

[0053] The mixing element 41 in the mixing assembly 4 is used to mix and stir the raw materials inside the tank body 1. The processing element 42 is used to drive the raw materials at the bottom of the tank body 1 to improve the mixing effect of the raw materials. The scraper element 43 is used to clear the slurry on the inner surface of the tank body 1, which can not only avoid the problem of raw material adhesion, but also further improve the uniformity of the raw material mixing.

[0054] The back of the tank body 1 is provided with a surge assembly 5 for surging the slurry inside the tank body 1. The surge assembly 5 includes a pumping member 51 for discharging the slurry above or below the tank body 1 to the bottom or above the tank body 1 and a driving member 52 for driving the pumping member 51. The pumping member 51 is connected to the mixing member 41 through the driving member 52.

[0055] By setting the driving member 52 in the surging component 5, the rotational driving force of the mixing member 41 is transmitted to the pumping member 51, and the slurry inside the tank body 1 is sucked and discharged through the pumping member 51, so that the slurry inside the tank body 1 surges, thereby improving the slurry mixing effect and reducing the problem of mixing blind spots.

[0056] See attached Figure 5 The mixing element 41 includes a mixing frame 411 rotatably connected to the top of the inner wall of the tank body 1 and a motor 412 fixed to the top of the tank body 1 through a bracket. The top of the mixing frame 411 extends to the top of the tank body 1, and the output shaft of the motor 412 is fixedly connected to the top of the mixing frame 411;

[0057] The motor 412 is connected to an external power source and a control switch, and is a forward and reverse motor, and is configured using the connection method and encoding method of the prior art, and is used to drive the mixing frame 411 to rotate. By rotating the mixing frame 411, the raw materials inside the tank body 1 can be mixed and stirred.

[0058] See attached Figure 5 The processing member 42 includes a connecting frame 421 fixed to the bottom of the mixing frame 411, and two scraping plates 422 are fixedly connected to the bottom of the connecting frame 421, and the bottoms of the two scraping plates 422 are in contact with the bottom of the tank body 1;

[0059] By rotating the mixing frame 411, the two scraping plates 422 can also be driven to rotate through the connecting frame 421, so that the two scraping plates 422 can clean the inner bottom of the tank body 1 to prevent the raw materials from settling at the bottom of the tank body 1 and affecting the subsequent uniform mixing effect.

[0060] Embodiment 2: Based on embodiment 1, the difference is that;

[0061] See attached Figures 5 to 7 The scraper member 43 includes a fixed plate 431 fixed to the outer surface of the top of the mixing frame 411, and a curved scraper 432 is fixedly connected to one side of the bottom of the fixed plate 431, and one side of the curved scraper 432 contacts the inner surface of the tank body 1;

[0062] By rotating the mixing frame 411, the fixed plate 431 can drive the arc scraper 432 to rotate, and then the arc scraper 432 can scrape the raw materials on the inner surface of the tank body 1 to prevent the raw materials from adhering before mixing, which not only easily causes pollution inside the tank body 1 and affects the subsequent mixing work, but also easily causes waste of slurry;

[0063] The arc scraper 432 is rotatably connected to a rotating shaft 433, and the outer surface of the rotating shaft 433 is fixedly connected to at least one shifting piece 434. The top of the rotating shaft 433 is fixedly connected to a gear 435. The top of the inner wall of the tank body 1 is fixedly connected to a toothed sleeve 436, and the inner surface of the toothed sleeve 436 meshes with the outer surface of the gear 435. A plurality of strip-shaped penetration holes 437 are opened on one side of the inner side of the arc scraper 432.

[0064] The gear 435 is meshed with the inner surface of the toothed sleeve 436, so that the gear 435 can roll on the inner surface of the toothed sleeve 436 during the circular motion, and then the toggle plate 434 can be driven to rotate through the rotating shaft 433;

[0065] By rotating the toggle piece 434, the inner surface of the arc scraper 432 can be scraped to prevent the material from adhering to the inner surface of the arc scraper 432 when the arc scraper 432 is scraping the inner surface of the tank body 1;

[0066] Combined with the circular motion of the arc scraper 432, the loose slurry inside the arc scraper 432 can be flushed by the slurry inside the tank body 1, and the blocky raw materials can be broken and separated through a plurality of strip-shaped penetration holes 437, further avoiding the problem of raw material lumps affecting the raw material mixing effect.

[0067] Embodiment 3: Based on embodiment 1, the difference is that;

[0068] See attached Figure 8 The pumping member 51 includes a negative pressure cylinder 511 fixed to the outer surface of the tank body 1, the bottom of the negative pressure cylinder 511 is fixedly connected to two pumping pipes 512, and both pumping pipes 512 are installed with a one-way valve, the inside of the negative pressure cylinder 511 is slidably connected to a piston plate 513 that can be driven up and down, and the top of the piston plate 513 is fixedly connected to a driving rod 514;

[0069] By driving the piston plate 513 up and down through the driving rod 514, the slurry inside the tank body 1 can be sucked through one of the pumping and draining pipes 512, and then discharged into the tank body 1 again through the other pumping and draining pipe 512, which not only forms the slurry surge in the tank body 1, improves its mixing effect, and reduces its mixing blind area, but also can circulate and replace the slurry above and below the tank body 1, thereby avoiding the precipitation and stratification of the slurry and reducing the quality of the subsequent board;

[0070] The two one-way valves are installed in an opposite one-way blocking manner, which not only makes it easy for the slurry in the upper layer to flush the slurry in the lower layer to avoid the sedimentation and accumulation of the slurry, but also makes it easy to discharge the slurry in the lower layer to the upper layer, forming a slurry surge, thereby improving the slurry mixing effect.

[0071] The driving member 52 includes a reciprocating screw 521 rotatably connected between the tank body 1 and the top of the negative pressure cylinder 511 through a bracket, the outer surface of the reciprocating screw 521 is transmission-connected with a reciprocating block 522, and the reciprocating block 522 is fixedly connected to the top of the driving rod 514, and the top of the reciprocating screw 521 is transmission-connected to the mixing frame 411 through a belt group 523;

[0072] By rotating the mixing frame 411 in the mixing element 41, not only can the slurry inside the tank body 1 be mixed and stirred, but also the reciprocating screw 521 can be driven to rotate by the belt group 523, and the rotation of the reciprocating screw 521 can drive the reciprocating block 522 to reciprocate up and down, and then the piston plate 513 can be driven to reciprocate up and down by the driving rod 514, so as to form the pumping and surging work of the slurry, which fully utilizes the driving force of the slurry mixing and stirring, and does not need to add an additional electric driving source for driving, thereby improving the energy saving and environmental protection of the slurry mixing equipment;

[0073] The belt group 523 is composed of a belt and two pulleys, and the two pulleys are connected by belt transmission. The pulley fixedly connected to the reciprocating screw 521 is connected by a one-way bearing. The inner ring of the one-way bearing is fixedly connected to the reciprocating screw 521, and the outer ring is fixedly connected to the pulley, so that when the mixing frame 411 rotates clockwise, the reciprocating screw 521 can be driven to rotate by the belt group 523 to form a slurry surging operation; on the contrary, when the mixing frame 411 rotates counterclockwise, the reciprocating screw 521 cannot be driven to rotate by the belt group 523, thereby facilitating the mixing component 4 to perform the slurry mixing operation alone.

[0074] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article, or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.
