Description

Technical Field

[0001] This utility model relates to the field of gypsum production technology, and more specifically, to a continuous hydrophobic phosphogypsum production device. Background Technology

[0002] Gypsum blocks are made from natural gypsum, phosphogypsum, and other inorganic materials as the main raw materials. They are lightweight and high-strength, fireproof and heat-insulating, sound-insulating and heat-preserving, can be sawed and planed, have a low breakage rate, are easy to install, have a fast construction speed, are not limited by wall height, reduce labor intensity, and reduce wet work. In construction, gypsum blocks can reduce the building's weight, save steel and cement, increase usable area, reduce project costs, and improve the building's seismic resistance when used as interior partition walls. The production of gypsum blocks involves mixing raw materials and then pouring the mixture into molds to form the blocks.

[0003] Phosphogypsum slurry contains fibers and hydrophobic agents. Traditional mixers can easily cause fiber agglomeration or uneven distribution of the organic phase, affecting the strength and hydrophobicity of the product. During the curing of phosphogypsum casting, air bubbles are easily left in the finished gypsum product and solidify, making the product prone to cracking and affecting its quality. In continuous production, gypsum powder residues accumulate and solidify in the tank, affecting the smooth flow of materials. The accumulated residues can also interfere with the proportioning of subsequent raw materials, affecting the consistency of the finished product. Furthermore, the solidified residues require shutdown and high-pressure water cleaning, which can disrupt the continuous production schedule. Utility Model Content

[0011] The driving unit is driven to rotate horizontally or move vertically, and when the mixing unit contacts the cleaning unit, the cleaning unit is driven to rotate synchronously.

[0012] The positioning part is used to guide and adjust the mold that is moving at a constant speed on the plate conveyor, and the two vibration parts are used to reciprocate to strike both sides of the mold when the mold passes the positioning part.

[0024] This continuous hydrophobic phosphogypsum production device features a drive unit that controls the mixing unit to rotate while simultaneously moving vertically. During the vertical movement of the frame-type mixing frame, the interference flow plate effectively shears the slurry, ensuring uniform distribution of fiber raw materials in the gypsum slurry and guaranteeing the strength and hydrophobicity of the product. Furthermore, when the finished gypsum slurry is injected into the mold, the drive unit controls the rotating rod and frame-type mixing frame to move down to their limit positions and engage with the cleaning unit. This allows the rotation of the rotating rod and frame-type mixing frame to drive the cleaning unit to rotate synchronously, effectively scraping and cleaning the inner wall of the mixing tube. This prevents residues from affecting the subsequent raw material ratio, ensuring the quality and consistency of the finished product. Moreover, it eliminates the need for machine shutdown for cleaning, ensuring continuous production.

[0025] This continuous hydrophobic phosphogypsum production device, through its positioning unit, allows for fine-tuning of the mold during conveying by the plate conveyor, ensuring the mold is centered on the conveyor. Furthermore, when gypsum slurry is injected into the mold, several rubber hammers from two vibrating units synchronously and periodically strike both sides of the mold, causing air bubbles in the slurry to rise and escape. This effectively improves the density of the finished gypsum product, enhances the hydration reaction efficiency of the phosphogypsum within the mold, forms high-strength hydrophobic products, and guarantees the quality of the finished product.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0036] like Figure 1-6 As shown, a continuous hydrophobic phosphogypsum production device includes: a plate conveyor 1, with supports 2 symmetrically arranged on both sides of the plate conveyor 1, and a mixing tank 3 fixedly installed on the top of several supports 2, with a closed cover 4 installed on the top of the mixing tank 3.

[0037] Positioning part 5, the positioning part 5 is fixed on the plurality of plate conveyors 1 and the plurality of supports 2;

[0038] Vibration part 6, two vibration parts 6 are symmetrically arranged on the positioning part 5;

[0039] Mixing unit 7, which is mounted on the mixing tank 3;

[0040] Cleaning section 8 is disposed inside the mixing tank 3 and partially intersects the mixing section 7;

[0041] A drive unit 9 is mounted on the upper end of the sealing cover 4, and the output end of the drive unit 9 is fixedly connected to the mixing unit 7, wherein:

[0042] The driving unit 9 is driven to rotate the mixing unit 7 horizontally or move vertically, and when the mixing unit 7 contacts the cleaning unit 8, the cleaning unit 8 is driven to rotate synchronously.

[0043] The positioning part 5 is used to guide and adjust the mold that is moving at a constant speed on the plate conveyor 1, and the two vibration parts 6 are used to reciprocate to strike both sides of the mold when the mold passes through the positioning part 5.

[0044] In use, through multiple feed pipes 37 on the closed cover 4, raw materials such as α-type hemihydrate phosphogypsum, water, polyester fiber, polyorganosiloxane, fly ash, and silicate cement are fed into the mixing tank 3 in proportion. The feed pipes 37 are designed to be packaged separately to avoid premixing clumping.

[0045] Next, the drive unit 9 starts, and the drive motor 16 drives the rotating rod 10 and the frame-type stirring frame 11 to rotate. The baffle plate 12 enhances the turbulence of the slurry to mix the raw materials. At the same time, the drive unit 9 can control the rotating rod 10 and the frame-type stirring frame 11 to move vertically while rotating, so that the baffle plate 12 can effectively shear the gypsum slurry in the mixture, thereby ensuring that the fiber raw materials are evenly distributed in the gypsum slurry, ensuring the strength and hydrophobicity of the product, and ensuring stable hydrophobic performance.

[0046] After the gypsum raw materials are mixed, the mixed thick slurry is discharged through the bottom discharge pipe 38. The solenoid valve controls the discharge flow rate of the discharge pipe 38 to match the speed of the plate conveyor 1. When the plate conveyor 1 connects and transports multiple molds, the slurry is injected into the molds that are moving at a uniform speed. When the mold passes the positioning part 5, two guide chute 26 and several positioning rollers 28 work together to correct the mold position. At the same time, the vibration parts 6 on both sides of the positioning part 5 work simultaneously to drive several rubber hammers 36 to strike both sides of the mold, remove air bubbles in the slurry during injection, eliminate density gradients, effectively improve the density of the gypsum product, and ensure the quality of the finished product without cracking defects.

[0047] While the material is being injected, the mixing section 7 moves down to its limit position under the control of the drive section 9 and engages with the cleaning section 8. This causes the rotation of the rotating rod 10 and the frame-type mixing frame 11 to drive the cleaning section 8 to rotate synchronously, effectively scraping and cleaning the inner wall of the mixing tube. This prevents residues from affecting the subsequent raw material ratio, ensuring the quality and consistency of the finished product. Furthermore, due to the automatic operation of the cleaning section 8, there is no need to stop the machine for cleaning, ensuring equipment utilization and production continuity. At the same time, the cleaning section 8 uses hybrid power drive, requiring no additional energy consumption and reducing costs.

[0048] Optionally, the mixing unit 7 includes a rotating rod 10 fixed to the lower end of the driving unit 9 and movably connected to the closed cover 4; a frame-type stirring frame 11 fixed to the lower end of the rotating rod 10 and disposed inside the mixing tank 3; and a small disturbance flow plate 12 symmetrically fixed on the frame-type stirring frame 11. In use, the driving unit 9 drives the rotating rod 10 to rotate, so as to transmit the rotational force to the frame-type stirring frame 11. When the powder raw material is added into the mixing tank 3, the frame-type stirring frame 11 rotates and disperses the powder raw material. After the liquid raw material is added into the mixing tank 3, under the control of the driving unit 9, the frame-type stirring frame 11 can be controlled to rotate and move vertically at the same time. With the small disturbance flow plate 12, the high viscosity slurry can be effectively sheared, so that the polyester fiber is effectively dispersed in the vortex formed by the disturbance plate 12, avoiding agglomeration, thereby effectively mixing the raw materials and ensuring the quality of the gypsum product.

[0049] Optionally, the drive unit 9 includes a control frame 13 fixed to the upper surface of the closed cover 4; two synchronous hydraulic rods 14 symmetrically fixed to the outer wall of the control frame 13; an assembly frame 15 fixed to the telescopic ends of the two synchronous hydraulic rods 14 and movably installed in the control frame 13; a drive motor 16 installed on the upper surface of the assembly frame 15; a plurality of guide grooves 17 arranged in a ring array on the assembly frame 15; and a plurality of guide rods 18 arranged in a ring array fixed in the control frame 13 and respectively fitted and slidably inserted into the plurality of guide grooves 17.

[0050] The upper end of the rotating rod 10 is fixedly connected to the output end of the drive motor 16;

[0051] When in use, the two synchronous hydraulic rods 14 work simultaneously, which can drive the assembly frame 15 to move vertically along the guide rod 18, thereby adjusting the mixing depth of the mixing part 7 and facilitating the control of the mixing part 7 contacting the cleaning part 8. The cooperation of several guide grooves 17 and several guide rods 18 can ensure the stability of the vertical movement of the assembly frame 15 and prevent the assembly frame 15 from shifting.

[0052] When the raw materials in the mixing tank 3 need to be mixed, the drive motor 16 drives the mixing part 7 to rotate, and stirs and mixes the raw materials. The rotation speed can be controlled by the motor frequency converter to adapt to slurries of different viscosities. During the rotation of the mixing part 7, it can also move vertically to change the mixing position and adjust the stirring depth, so that the raw materials can be mixed evenly and effectively.

[0053] When cleaning is required inside the mixing tank 3, the two synchronous hydraulic rods 14 press down on the mounting frame 15 to control the mixing part 7 to move downward, thereby making the mixing part 7 contact the cleaning part 8. When the mixing part 7 rotates and mixes the raw materials in the mixing tank 3, it drives the cleaning rod 19 to scrape and clean the inner wall of the mixing tank 3. The cleaning action is only triggered when the mixing part 7 moves to the limit position, avoiding unnecessary friction and energy consumption, cleaning as needed, and reducing manual intervention.

[0054] Optionally, the cleaning unit 8 includes a plurality of cleaning rods 19 adapted to the inner wall of the mixing tank 3; a connecting frame 20 movably sleeved on the outside of the rotating rod 10 and used to connect the upper ends of the plurality of cleaning rods 19; a connecting ring 21 fixedly connected to the lower ends of the plurality of cleaning rods 19; a control disk 22 fixedly sleeved on the outside of the rotating rod 10 and disposed above the connecting frame 20; a plurality of push rods 23 fixed in a circular array on the control disk 22; and a plurality of push blocks 24 fixed in a circular array on the upper surface of the connecting ring 21.

[0055] A rubber scraper is fixedly connected to one side of each of the cleaning rods 19 near the inner wall of the mixing tank 3;

[0056] When the mixing unit 7 is normally mixing the raw materials in the mixing tank 3, the connecting frame 20, driven by its own weight and the weight of the connecting ring 21 and several cleaning rods 19, remains at the lower position of the rotating rod 10. At this time, there is a gap between the upper end of the connecting frame 20 and several push rods 23 on the control panel 22, ensuring that the two do not contact each other. Thus, when the rotating rod 10 rotates, the control panel 22 idles and does not contact or drive the connecting frame 20, keeping the cleaning unit 8 stationary. However, after a single gypsum mixing and injection, when cleaning of the inside of the mixing tank 3 is required, the drive unit 9 controls the mixing unit 7 to move vertically downward, causing the rotating rod 10 and the control panel 22 fixed on it to move downward until the control panel 22 is in contact with the connecting frame 20, and several push rods 23 are inserted into the connecting frame 20, and the mixture... The bottom of the frame-type mixing rack 11 in the mixing section 7 contacts the mixing section 7. When the driving section 9 controls the rotation of the mixing section 7, several push rods 23 contact the connecting frame 20, and several push blocks 24 contact the frame-type mixing rack 11. This allows the rotational motion of the mixing section 7 to be transmitted to the cleaning section 8, which drives several cleaning rods 19 to scrape and clean the inner wall of the mixing tank 3, removing the adhering slurry. The cleaning frequency is synchronized with the mixing speed, achieving real-time cleaning, avoiding residue accumulation, preventing batch-to-batch contamination caused by incomplete cleaning, and ensuring the performance stability of the hydrophobic phosphogypsum. The rubber scraper prevents the cleaning rods 19 from making hard contact with the wall of the mixing tank 3, preventing wear on the coating of the inner wall of the mixing tank 3. Furthermore, the cleaning section is directly driven by the power of the mixing section 7, eliminating the need for a separate motor or pneumatic system, resulting in significant energy savings.

[0057] Meanwhile, since the drive unit 9 drives the mixing unit 7 to move down and trigger the cleaning unit 8 to work only when cleaning is needed, when the cleaning unit 8 is stationary, several rubber scrapers do not rub against the wall of the mixing tank 3, avoiding unnecessary friction damage to the cleaning unit 8 during production, effectively improving its service life, and can also reduce the load energy consumption of the drive unit 9. The connecting frame 20 can adopt a snap-on design to connect with several cleaning rods 19, making it easy to replace the rubber scrapers.

[0058] Optionally, the positioning part 5 includes two positioning boxes 25 symmetrically fixed above the plate conveyor 1; a guide chute 26 disposed on one side of the two positioning boxes 25 close to each other; two reinforcing frames 27 fixedly sleeved on the outside of several brackets 2 and respectively fixedly connected to the two positioning boxes 25; and several positioning rollers 28 rotatably mounted on one side of the two positioning boxes 25 close to each other and abutting against the mold.

[0059] A rubber sleeve is fixedly fitted onto the outer wall of each of the positioning rollers 28;

[0060] When the mold is conveyed by the plate conveyor 1 and moves to the positioning part 5, it is first coarsely positioned by the two guide spurs 26 on the two positioning boxes 25 to correct the initial offset. During continuous conveying, it comes into contact with several positioning rollers 28. The positioning rollers 28 roll on both sides of the mold and use the friction of the rubber sleeve to finely adjust the position of the mold to ensure that it is strictly centered and to ensure the accuracy of the subsequent vibration part 6 striking the mold. In addition, the rubber sleeve can prevent the metal rollers from directly contacting the mold and causing wear, effectively extending the mold life.

[0061] Optionally, the vibration unit 6 includes a control plate 29 disposed within one of the positioning boxes 25; a plurality of striking rods 30 fixed in a rectangular array on the control plate 29 and passing through the positioning box 25; a plurality of return springs 31 movably sleeved on the outside of the plurality of striking rods 30 and fixedly connected at both ends to the control plate 29 and the inner wall of the positioning box 25 respectively; a control rod 32 rotatably mounted in the positioning box 25 via a bearing seat; two cams 33 symmetrically fixed on the control rod 32 and abutting against the control plate 29; a control motor 34 mounted in the positioning box 25; and two transmission gears 35 fixed at the output end of the control motor 34 and the lower end of the control rod 32 and meshing with each other.

[0062] A rubber hammer head 36 is fixedly connected to the other end of each of the aforementioned striking rods 30;

[0063] The mold is positioned by the positioning part 5 and conveyed by the plate conveyor 1 to the bottom of the mixing tank 3. When the center area of ​​the mold side wall is aligned with the vibrating part 6, the control motor 34 starts and drives the control rod 32 to rotate through the meshing transmission gear 35. This causes the two cams 33 fixed on the control rod 32 to rotate, and their eccentric structure periodically pushes the control plate 29 to move towards the mold. The movement of the control plate 29 causes several striking rods 30 to move forward synchronously, so that several rubber hammers 36 at the ends of the striking rods strike the mold synchronously. With sidewalls, it generates high-frequency vibration, which causes air bubbles in the gypsum slurry to rise and escape quickly, effectively increasing the density of the finished product and ensuring its compressive strength. The rubber hammer head 36 can buffer the impact force and prevent slurry from splashing while protecting the mold. Under the elastic push of several return springs 31, the control plate 29 is immediately pulled back to its original position after being struck, ready for the next strike. With the cooperation of the two vibrating parts 6, synchronous striking of both sides of the mold is achieved, ensuring that the mold is subjected to uniform force and avoiding slurry stratification or uneven density caused by unilateral force.

[0064] Optionally, the sealing cover 4 is connected to a plurality of feed pipes 37, the bottom of the mixing tank 3 is connected to a discharge pipe 38, and a solenoid valve is installed on the discharge pipe 38.

[0065] The multi-feed pipe 37 separates powder and liquid raw materials, which facilitates the separate feeding of different materials such as powdered α-type hemihydrate phosphogypsum, water, polyester fiber, polyorganosiloxane, fly ash, and silicate cement, avoiding premixing and clumping that could affect subsequent mixing. When the finished gypsum slurry is discharged into the mold through the discharge pipe 38, the solenoid valve can control the slurry flow rate and link the conveyor speed to ensure consistent mold filling.

[0066] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
