Description

Material mixing equipment and gypsum board production system

[0001] This application claims priority to the Chinese patent application filed on February 29, 2024, with application number 202410231926.5 and invention name “Material Mixing Equipment and Gypsum Board Production System”, the content of which should be understood as incorporated into this application by reference. Technical Field

[0002] This article relates to but is not limited to the field of gypsum technology, and in particular to a material mixing device and a gypsum board production system. Background Art

[0003] Gypsum board is environmentally friendly, soundproof, heat-insulating, fireproof, non-toxic, moisture-resistant, and waterproof. Furthermore, it offers excellent comfort, making it a widely used and essential material in modern interior decoration. Currently, integrating phase change materials with gypsum board to impart energy storage and heat release capabilities is a key research direction and aligns with national policies promoting carbon neutrality and peak carbon emissions.

[0004] While gypsum board offers many advantages, its production is complex. The main production process involves calcining raw gypsum to produce gypsum plaster, grinding the gypsum to produce the required gypsum powder. This powder is then fed into a mixer, where starch, glass fiber, water, foaming agent, setting regulator, waterproofing agent, water reducer, and other additives are added to create a gypsum slurry. The slurry is then spread between two layers of paper, which are then folded and sealed to adhere. The slurry sets initially and finally on a forming machine belt, and is then cut into slabs of a desired length. The slabs are then dried in a kiln to remove excess moisture, sealed, and packaged to produce the finished gypsum board.

[0005] In the production process of phase change gypsum board, the mixing of loaded phase change material particles and slurry is very important. However, the loaded phase change material particles currently have the problem of not being fully mixed with the gypsum slurry, thus affecting the performance of the gypsum board product.

[0030] In addition, when describing representative embodiments, the specification may have presented the method and / or process as a specific sequence of steps. However, to the extent that the method or process does not rely on the specific order of the steps described herein, the method or process should not be limited to the steps in the specific order described.

[0031] There are many types of phase change materials for producing phase change gypsum boards. Among them, a phase change material (such as paraffin) is adsorbed in the cavities of mineral particles through mineral loading, and then the mineral particles are coated to obtain a phase change material. Due to the internal pores of the mineral particles, the density of the mineral particles is less than the density of water. In addition, the density of paraffin is also less than the density of water. Finally, the density of the loaded phase change material particles is also less than the density of water. Experiments have shown that the loaded phase change material particles basically float on the water surface. If the loaded phase change material particles are directly added to the mixer for stirring, although the stirring is relatively uniform, the structural strength of the loaded phase change material particles is very poor. After the high-speed stirring impact of the mixer, the loaded phase change material particles will be broken, resulting in the leakage of the phase change material (paraffin), affecting the energy storage effect of the product. If the loaded phase change material particles are directly sprinkled on the surface of the slurry and then stirred, the loaded phase change material particles will be difficult to integrate into the interior of the slurry due to the low density of the loaded phase change material particles, and finally the loaded phase change material particles in the slurry will be unevenly distributed, with more on the upper part of the slurry and less on the lower part. After spraying on the gypsum board paper, during the period until the final setting, the loaded phase change material particles will migrate upward due to the buoyancy of the loaded phase change material particles due to the low density and lightness, resulting in more on the front side of the gypsum board (i.e. the upper part of the slurry) and less on the bottom side of the gypsum board (i.e. the lower part of the slurry), which will eventually affect the overall performance of the gypsum board product.

[0032] In order to solve the problem of mixing particulate material and slurry, an embodiment of the present application provides a material mixing device, as shown in Figures 1 and 2, the material mixing device includes a mixing tank 4 and a mixing device located in the mixing tank 4. The first material and the second material enter the mixing tank 4 and are mixed by the mixing device;

[0033] The mixing device includes a first dispersing component 51 and a second dispersing component 52 located below the first dispersing component 51; wherein, the first material entering the mixing tank 4 is configured to fall from above the first dispersing component 51 along the first dispersing component 51 for dispersion, and the second material entering the mixing tank 4 is configured to fall from below the first dispersing component 51 along the second dispersing component 52 for dispersion, so that the dispersed first material and the second material are mixed during the falling process.

[0034] The first material is usually slurry, and the second material can be granular material, powder or other types of material.

[0035] The technical solution provided by the embodiments of the present application disperses the first and second materials during their falling process, with the first material covering the second material below from above during the falling process to achieve mixing between the two. Furthermore, during the falling process, the first material, dispersed by the first dispersing component 51, splashes onto the inner wall of the mixing tank 4 and flows downward along the inner wall. The second material, falling onto the second dispersing component 52, also splashes onto the inner wall of the mixing tank 4. Consequently, the first and second materials mix on the inner wall of the mixing tank 4. Simultaneously, the first material, reflected by the inner wall of the mixing tank 4, mixes again with the falling second material. Thus, within the mixing tank 4, the first and second materials mix multiple times due to the interaction of the inner wall of the mixing tank 4. This mixing method avoids uneven distribution caused by the low density of the second material and does not disrupt the structure of the materials (for example, in the case of granular second materials). Therefore, this material mixing device is suitable for mixing gypsum slurry with phase change material particles to produce phase change gypsum board (although it can also be applied in other fields). In specific applications, the slurry (first material) stirred by the slurry mixer enters the mixing tank 4 of the material mixing equipment, and is dispersed by the first dispersing component 51 when the slurry falls. At the same time, the phase change material particles (second material) enter the mixing tank 4 and are dispersed by the second dispersing component 52 under the dispersed slurry. In this way, under the action of gravity, the dispersed particles below are covered by the dispersed slurry above and mixed. This way of mixing materials can effectively mix the slurry and the phase change material particles without destroying the structure of the phase change material particles, ensuring that the phase change material (such as paraffin) will not flow out of the particles, thereby reducing the impact on the performance of the phase change gypsum board.

[0036] In one embodiment, the first dispersing component 51 is a conical structure with a gradually expanding diameter from top to bottom, and the first material can be dispersed 360 degrees when it falls on the first dispersing component 51; the second dispersing component 52 is a conical structure with a gradually expanding diameter from top to bottom, and the second material can be dispersed 360 degrees when it falls on the second dispersing component 52.

[0037] In the example shown in FIG1 , the maximum diameter of the first dispersing component 51 is smaller than the maximum diameter of the second dispersing component 52. Thus, the second material can be dispersed over a larger range by the second dispersing component 52. The first material covers the second material during its falling process and is further dispersed by the second dispersing component 52, thereby more effectively mixing the first material and the second material.

[0038] In one embodiment, as shown in Figures 1 and 2, the material mixing equipment also includes a slurry mixer 2, and the slurry output pipe 25 of the slurry mixer 2 is configured to input the slurry as the first material from above the first dispersing component 51, so that the slurry can fall on the first dispersing component 51 and be dispersed.

[0039] In one example, the slurry mixer 2 may include a housing, a fixed frame 21 fixed relative to the housing, and a rotating frame 23 rotating relative to the fixed frame 21, wherein a plurality of fixed rods 22 are fixed to the fixed frame 21, and a plurality of moving rods 24 are fixed to the rotating frame 23, wherein the plurality of moving rods 24 and the plurality of fixed rods 22 are inserted into the space between each other. The rotating frame 23 is connected to a drive shaft 26, and a slurry mixing motor 27 drives the drive shaft 26 to rotate via a transmission belt 28, thereby driving the plurality of moving rods 24 on the rotating frame 23 to rotate. After the material (e.g., gypsum powder, water, starch, glass fiber, foaming agent, water reducing agent, setting agent, etc.) is fed into the housing of the slurry mixer 2, the rotating frame 23 rotates with the plurality of moving rods 24, and the plurality of moving rods 24 cooperate with the plurality of fixed rods 22 to achieve mixing of the slurry, and the mixed slurry is output from the slurry output pipe 25 to the mixing tank 4. Of course, it is understood that the structure of the slurry mixer 2 is not limited to that shown above, and may also be other devices capable of inputting the first material.

[0040] In one embodiment, the material mixing apparatus further includes a screw conveyor 3, which conveys the second material between the first dispersing component 51 and the second dispersing component 52, so that the second material falls from below the first dispersing component 51 along the second dispersing component 52. As shown in FIG1 , the screw conveyor 3 extends into the mixing tank 4 through an opening provided in the side wall of the mixing tank 4. The housing of the screw conveyor 3 can be fixed to the side wall of the mixing tank 4 via a fixing bracket, and a seal is provided to seal the gap between the screw conveyor 3 and the mixing tank 4.

[0041] 1 , 2 and 4 , the first dispersing component 51 and the second dispersing component 52 are respectively conical structures, and the discharge port of the screw conveyor 3 is aligned with the center position of the second dispersing component 52. The first dispersing component 51 can be installed on the top of the screw conveyor 3, and the center position corresponds to the center position of the second dispersing component 52 up and down.

[0042] It is understood that the second material is not limited to being conveyed by the screw conveyor 3, and a conveying pipeline extending between the first dispersing component 51 and the second dispersing component 52 may also be provided. In another embodiment, to prevent the screw conveyor 3 or the conveying pipeline from obstructing the fall of the first material, the second material may be discharged upward from a middle position below the second dispersing component 52 and then fall along the second dispersing component 52. In other words, the second material may be first conveyed to the bottom of the second dispersing component 52 and then conveyed upward to the top of the second dispersing component 52.

[0043] In one embodiment, the second dispersing component 52 is rotatable, and during the rotation, the second material is dispersed by centrifugal force and drives the first material to disperse, thereby making the mixing more complete.

[0044] As shown in the examples of FIG. 1 and FIG. 2 , the material mixing device further includes a rotating shaft 53 and a driving mechanism 6 for driving the rotating shaft 53 to rotate, wherein the second dispersing component 52 is mounted on the rotating shaft 53 to be driven to rotate by the rotating shaft 53 .

[0045] The material mixing equipment further comprises a frame 1 , and a mixing tank 4 is mounted on the frame 1 ; wherein the frame 1 comprises a support frame 11 extending into the mixing tank 4 , and a rotating shaft 53 is rotatably provided through a bearing 537 provided on the support frame 11 .

[0046] As shown in the example of FIG1 , a horizontally arranged support frame 11 is provided at a certain height position of the frame 1, and the support frame 11 extends into the mixing tank 4 for mounting the rotating shaft 53. Referring to the examples shown in FIG3 and FIG5 , the support frame 11 may include a cross 111 formed by a cross of square steel pipes, a mounting sleeve 534 is fixed at the center of the cross 111, a bearing sleeve 533 is provided in the mounting sleeve 534, and a bearing 537 is mounted in the bearing sleeve 533. In order to protect the bearing 537 and position the bearing from the end, a first bearing cap 535 is installed at one end of the mounting sleeve 534, and a second bearing cap 536 is installed at the other end, and the first bearing cap 535 is fixed at the center of the cross 111. Seals can be respectively arranged between the rotating shaft 53 and between the second bearing cover 536 and the rotating shaft 53. In addition, a slurry-proof sleeve 531 is provided between the bearing 537 and the second dispersing component 52 and is sleeved on the rotating shaft 53. A protective plate 532 is provided at the lower end of the slurry-proof sleeve 531 and is attached to the first bearing cover 535. The protective plate 532 can be fixed on the mounting sleeve 534 or on the first bearing cover 535, so that the slurry falling from above will not enter the bearing 537.

[0047] In this example, the mixing tank 4 includes a dispersion tube 41 and a connecting tube 42 located below the dispersion tube 41. Four grooves can be set on the top of the connecting tube 42, and the four square steel pipes of the cross 111 of the support frame 11 are respectively inserted into the corresponding grooves. The dispersion tube 41 and the connecting tube 42 are both fixed to the support frame 11. Specifically, a threaded hole can be set on the support frame 11, and a step extending outward and having a connecting hole can be set at the bottom of the dispersion tube 41. The step at the bottom of the dispersion tube 41 can be fixed to the support frame 11 using bolts. In order to ensure the anti-seepage sealing effect, a rubber plate or sealant is installed on the contact surface between the dispersion tube 41 and the support frame 11. A convex step that cooperates with the support frame 11 can be set at the four grooves of the connecting tube 42, and the step is fixed to the support frame 11 by bolts, and the top of the connecting tube 42 is arranged to fit the bottom of the dispersion tube 41. In order to ensure the anti-seepage sealing effect, a rubber plate or sealant can be installed on the contact surface between the support frame 11 and the connecting tube 42. In addition, a rubber plate or sealant can be installed on the contact surface between the top of the connecting tube 42 and the bottom of the dispersion tube 41.

[0048] In one example, as shown in Figure 1, the driving mechanism 6 includes a motor 61 located outside the mixing tank 4, a driving pulley 62 driven by the motor 61, and a driven pulley 63 installed on the rotating shaft 53, and also includes a transmission belt 64 installed on the driving pulley 62 and the driven pulley 63; wherein the transmission belt 64 passes through an opening provided on the mixing tank 4 and enters the mixing tank 4, and a protective cover 65 is provided in the mixing tank 4 to cover the driven pulley 63 and the transmission belt 64.

[0049] 3 , the protective cover 65 may include a protective cover body 651 and a protective cover 652 that cooperates with the protective cover body 651. The protective cover body 651 and the protective cover 652 internally form a receiving space for the driven pulley 63 and the transmission belt 64. Both the protective cover body 651 and the protective cover 652 are provided with a center hole for the rotation shaft 53 to pass through. During installation, the center hole of the protective cover body 651 is first passed through from below the rotation shaft 53. The protective cover body 651 can be fixed to the second bearing cap 536 or a structure fixed relative to the support frame 11 by bolts. The driven pulley 63 is then passed through from below the rotation shaft 53 and into the protective cover body 651. The driven pulley 63 can be installed by cooperating with, for example, a flat key provided on the rotation shaft 53. The transmission belt 64 is then installed on the driving pulley 62 and the driven pulley 63. A shield cover 652 is installed under the driven pulley 63. The shield cover 652 can be fixed to the shield body 651 by bolts. In addition, the shield 65 can also be fixed to the side wall of the mixing tank 4 by a fixing bracket 66. In order to prevent the slurry from entering the transmission belt or pulley and affecting the work, it is necessary to set the shield 65 and the opening of the mixing tank 4 to be sealed. The specific sealing structure can be implemented by those skilled in the art and will not be elaborated here.

[0050] In one embodiment, the mixing tank 4 includes a dispersion cylinder 41 and a stirring cylinder 43 located below the dispersion cylinder 41, a first dispersion component 51 and a second dispersion component 52 are located in the dispersion cylinder 41, and the mixing device also includes a stirring component 54 located in the stirring cylinder 43, and the stirring component 54 is installed on the rotating shaft 53, so that the rotating shaft 53 drives the second dispersion component 52 to rotate while also driving the stirring component 54 to rotate, thereby stirring and mixing the material in the stirring cylinder 43.

[0051] A connecting cylinder 42 can be provided between the dispersion cylinder 41 and the mixing cylinder 43. The dispersion cylinder 41 is connected to the upper end of the connecting cylinder 42, and the mixing cylinder 43 is connected to the lower end of the connecting cylinder 42. The transmission belt 64 of the drive mechanism 6 passes through the connecting cylinder 42 and enters the mixing cylinder 4. The separate arrangement of the mixing tank 4 not only facilitates manufacturing but also facilitates the installation of various components.

[0052] As shown in Figures 1 to 3, the stirring component 54 includes a plurality of stirring rods mounted on the rotating shaft 53. The plurality of stirring rods may include long stirring rods and short stirring rods shorter than the long stirring rods. Referring to Figure 7, the long stirring rods and the short stirring rods may be arranged alternately.

[0053] As shown in Figure 3, a spacer 538 can be provided on the rotating shaft 53, and the spacer 538 extends to the lower part of the driven pulley 63, and can extend into the inside of the protective cover 65 or extend to the outside of the protective cover 65. Multiple stirring rods of the stirring component 54 are installed on the spacer 538, or an independent stirring component 54 is installed on the outside of the lower part of the spacer 538.

[0054] In one embodiment, a flow channel control mechanism 7 is provided below the mixing drum 43 , and the flow channel control mechanism 7 controls the size of the flow channel of the mixing drum 43 for material outflow.

[0055] The material dispersed from the first dispersing component 51 and the second dispersing component 52 falls into the mixing drum 43 under the action of gravity. At the beginning of the mixing, the bottom of the mixing drum 43 needs to be closed. When the material in the mixing drum 43 reaches a predetermined depth, it is opened again. After that, the amount of material falling into the mixing drum 43 and the amount of material flowing out of the mixing drum 43 can be matched, thereby ensuring that the material depth in the mixing drum 43 remains unchanged, and further ensuring that the mixing component 54 can stir the material in the mixing drum 43. The embodiment of the present application provides a flow channel control mechanism 7 below the mixing drum 43 to control the outflow of material from the mixing drum 43.

[0056] In the example shown in Figure 9, the flow channel control mechanism 7 includes a core shaft 72 rotatably mounted on the mixing tank 4 and a switch blade 71 driven to rotate by the core shaft 72, and also includes a control component for controlling the rotation of the core shaft 72. The rotation of the core shaft 72 is controlled by the control component to control the opening of the switch blade 71, thereby controlling the outflow of materials from the mixing drum 43.

[0057] In one example, referring to Figures 8-11 , the material mixing device further includes an angle positioning plate 78 fixed relative to the mixing tank 4. The angle positioning plate 78 is provided with a plurality of positioning holes. The control component includes a crank handle 73 for driving the core shaft 72 to rotate and a positioning component mounted on the crank handle 73. The positioning component includes a positioning pin 74, a spring 75, and a handle 76, and the handle 76 is connected to the positioning pin 74. Specifically, the crank handle 73 is provided with a mounting hole. The positioning pin 74 is located in the mounting hole. The spring 75 is sleeved on the positioning pin 74. A spring stopper 77 is also fixed in the mounting hole. The end of the spring 75 is located away from the angle positioning plate 78 and is used to stop the spring 75. One end of the handle 76 passes through the spring stopper 77 and is connected to the positioning pin 74. The other end of the handle 76 is located outside the mounting hole and is provided with a pull ring for manual pulling. The end of the positioning pin 74 facing the angle positioning plate 78 can extend from the mounting hole of the crank handle 73 and be inserted into the positioning hole of the angle positioning plate 78. When crank handle 73 is rotated to a predetermined position, spring 75 causes positioning pin 74 to be positioned in a corresponding positioning hole on angle positioning plate 78. Pulling handle 76 releases positioning pin 74 from the positioning hole, allowing crank handle 73 to be rotated for adjustment. Thus, according to the desired opening of switch plate 71, crank handle 73 is rotated to rotate switch plate 71 to a predetermined angular position. Then, handle 76 is released, and positioning pin 74 is positioned in the positioning hole to control the flow path.

[0058] In the example shown in FIG1 , the mixing tank 4 further includes a mixing drum 45 located below the stirring drum 43. A discharge port is provided at the bottom of the mixing drum 45, through which the materials mixed in the mixing tank 4 flow out. The flow channel control mechanism 7 is provided between the stirring drum 43 and the mixing drum 45.

[0059] Among them, a throttle pipe 44 can be set between the stirring drum 43 and the mixing drum 45, and a flow channel between the stirring drum 43 and the mixing drum 45 is formed in the throttle pipe 44. The flow channel control mechanism is installed on the throttle pipe 44. Among them, as shown in Figures 8 and 9, the cross-section of the throttle pipe 44 can be square, so that the switch blade 71 can be set to a square to facilitate the control of the opening of the throttle pipe 44.

[0060] In one example, a plurality of mixing plates 55 are disposed in a staggered manner from top to bottom within the mixing barrel 45, wherein each mixing plate 55 is tilted downward. The mixing barrel 45 may have a circular cross-section, and thus the mixing plates 55 are configured as semicircular plates, with the circular portions welded to the inner wall of the mixing barrel 45.

[0061] After the material stirred in the mixing drum 43 enters the mixing drum 45, it is first blocked by the first mixing plate 55. Under the action of the gravity of the material and the impact inertia, the material is dispersed and mixed. The mixed slurry passes through the gap between the first mixing plate 55 and the inner wall of the mixing drum 43, and flows along the pipeline of the mixing drum 43 to the other mixing plate 55. The slurry is dispersed and mixed again. In this way, the slurry is dispersed and mixed multiple times after passing through multiple mixing plates 55 above and below.

[0062] In some embodiments, the mixing tank 4 is mounted on a frame 1 , and a support panel 12 is further provided on the frame 1 below the discharge port of the mixing tank 4 , and the support panel 12 is configured to support the gypsum board paper.

[0063] When the material mixing equipment is used to manufacture gypsum board, gypsum board paper (the gypsum board lower paper located below the gypsum board to be manufactured) is laid on the support panel 12, and then the mixed material is spread on the gypsum board paper, and the gypsum board upper paper is laid above the logistics, and then the gypsum board product is obtained through processes such as condensation and drying.

[0064] The following describes a process of mixing a first material and a second material using a material mixing device in one embodiment, wherein in this embodiment, the first material is a slurry obtained by mixing gypsum powder and water by a slurry mixer 2, and the second material is phase change material particles conveyed by a screw conveyor 3.

[0065] The slurry stirred by the slurry mixer 2 enters the mixing tank 4 of the material mixing equipment, and is dispersed 360 degrees by the first dispersing component 51 during the falling process. At the same time, the phase change material particles are also input into the mixing tank 4 through the screw conveyor 3, and are dispersed 360 degrees by the second dispersing component 52 below the dispersed slurry. Under the action of gravity, the dispersed particles below are initially covered by the dispersed slurry above, achieving preliminary mixing. The preliminarily mixed slurry flows into the mixing drum 43 under the action of gravity to form a storage pool, and begins In this stage, the flow channel control mechanism 7 below the mixing drum 43 controls the flow channel below to close. When the total amount of slurry in the storage tank reaches the designed depth, the flow channel control mechanism 7 opens the flow channel. Thereafter, the flow channel remains in an open state, so that the slurry stirred in the mixing drum 43 flows into the mixing drum 45. At this time, the slurry and phase change particles entering the mixing tank 4 match the flow rate of the slurry flowing out of the mixing drum 43, thereby ensuring that the depth of the storage tank in the mixing drum 43 remains unchanged, and further ensuring that the stirring component 54 in the mixing drum 43 stirs the slurry at a low speed. The slurry, stirred in the mixing drum 43, flows out to the mixing drum 45. Due to the mixing plate 55 designed inside the mixing drum 45, the slurry flows through the mixing drum 45 under the action of gravity. After being mixed by the mixing plate 55, the phase change material particles and the slurry are fully mixed. At this time, the mixed slurry flows out of the mixing outlet of the mixing drum 45 and is spread on the gypsum paper supported by the supporting panel 12 below. It then undergoes processes such as initial and final setting, cutting, and drying to obtain a phase change gypsum board product. Because this process uses multiple low-speed mixing, the structure of the phase change material particles is not destroyed, thereby ensuring that the phase change material (paraffin) does not flow out of the particles, thereby ensuring the energy storage and heat release properties of the phase change gypsum board product.

[0066] An embodiment of the present application further provides a gypsum board production system, which includes the material mixing device 100 as described above.

[0067] FIG12 shows a gypsum board production system in an embodiment, including a material mixing device 100, a first paper reel 201, a first pulling device 202, a second paper reel 205 and a second pulling device 206. A support panel 12 is provided below the mixing outlet of the material mixing device 100. The gypsum board lower paper A pulled out from the first paper reel 201 by the first pulling device 202 is laid on the support panel 12, and the edge of the gypsum board lower paper A is indented and folded by the indentation device 203. After 100 has spread the mixed slurry on the lower paper A of the gypsum board, the second pulling device 206 pulls out the upper paper B of the gypsum board from the second paper roll 205 and places it on top of the slurry on the lower paper A of the gypsum board, so that the slurry is sandwiched between the two layers of paper. The upper and lower papers are folded and sealed to make the upper and lower papers stick together. Then the slurry completes initial and final setting on the conveyor belt 204 and is cut into gypsum slabs of a certain length. The gypsum slabs are then sent to a drying furnace for drying to remove excess moisture in the gypsum board. Finally, they are edge-sealed and packaged to obtain the gypsum board product.
