Description

Technical Field

[0001] This invention relates to the field of gypsum preparation, and more particularly to the preparation of α-type high-strength gypsum crystallization reactor. Background Technology

[0002] Alpha-type high-strength gypsum is a hemihydrate gypsum formed by dehydration and crystallization of dihydrate gypsum under saturated vapor pressure. It has a regular crystal structure, high density, and superior strength, wear resistance, and water resistance, making it widely used in precision casting, ceramic molds, medical applications, and high-end building materials. Alpha-type high-strength gypsum is formed by hydrothermal treatment of dihydrate gypsum in a closed saturated vapor pressure environment, causing it to slowly dehydrate, dissolve, and recrystallize in liquid water or a high-humidity atmosphere. This process promotes the formation of large, dense, and complete short columnar or prismatic crystals. Due to its complete crystal development, few defects, and dense structure, alpha-type hemihydrate gypsum exhibits a series of outstanding characteristics, including low standard consistency water requirement, low porosity of hydration products, and a dense structure.

[0003] The preparation of α-type high-strength gypsum requires a crystallization process, which is generally carried out in a crystallization reactor to guide the directional conversion of dihydrate gypsum into α-type hemihydrate gypsum. However, existing crystallization reactors suffer from poor uniformity of the crystallization environment and crude reaction solution addition methods, resulting in large local concentration and temperature gradients within the reactor. This easily leads to the formation of β-type impurities or excessively wide crystal particle size distribution, affecting product purity and strength stability. Furthermore, existing stirring methods cannot avoid eddies and dead zones, causing crystal sedimentation and agglomeration. Some crystals grow too quickly while others grow insufficiently, affecting the preparation of α-type high-strength gypsum. Summary of the Invention

[0041] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0042] Figures 1 to 13 The diagram shown is a structural schematic of an embodiment of the α-type high-strength gypsum crystallization reactor of the present invention.

[0043] A reactor for preparing α-type high-strength gypsum crystallization includes a reactor body support frame 1, which is equipped with various material inlet / outlet interfaces, measurement and monitoring interfaces, and other auxiliary interfaces. The liquid addition unit includes a liquid addition component 2 and a lifting component 3. The liquid addition component 2 is used to add liquid into the vessel support frame 1. The liquid addition component 2 is connected to the output end of the lifting component 3. The lifting component 3 is used to adjust the height of the output component of the liquid addition component 2. The output component of the liquid addition assembly 2 is slidably disposed in the inner cavity of the vessel support frame 1. The liquid supply component of the liquid addition assembly 2 is installed on the outside of the vessel support frame 1. The lifting assembly 3 is installed in the inner cavity of the mounting frame 4. The mounting frame 4 is connected to the outside of the vessel support frame 1. The lifting assembly 3 is connected to the liquid processing mechanism. The liquid processing mechanism is disposed in the liquid supply component of the liquid addition assembly 2 and is used to mix the liquid in the liquid addition assembly 2. A mixing unit is provided in the inner cavity of the vessel support frame 1. The upper end of the mixing unit is connected to the output end of the stirring drive device 5. The stirring drive device 5 is installed on the top of the vessel support frame 1. The stirring drive device 5 drives the mixing unit to rotate and stir the material in the vessel support frame 1.

[0044] In this technical solution, the reaction liquid is uniformly added into the support frame 1 of the reactor body through the liquid addition component 2. At the same time, the height of the output component of the liquid addition component 2 is adjusted by the lifting component 3, so that the reaction liquid is uniformly added to different heights in the crystallization reactor, making the liquid addition of the entire crystallization reactor more uniform, so as to facilitate the formation of α-type high-strength gypsum crystals. Furthermore, the lifting component 3 can drive the liquid handling mechanism to operate during operation. By converting the up-and-down movement of the lifting component 3 into a rotational movement, the rotation is used to stir and mix the reaction liquid in the liquid supply component of the liquid addition component 2, and to pre-treat the reaction liquid, thereby improving the rate of uniform mixing. Furthermore, the output component of the liquid addition assembly 2 is attached to the inner wall of the vessel support frame 1. When the lifting assembly 3 moves the liquid addition assembly 2 up and down, it can clean the inner wall of the vessel support frame 1 at the same time, preventing crystals from adhering to the inner wall of the vessel support frame 1, and making the discharge smoother. Furthermore, the stirring unit is driven by the stirring drive device 5. This stirring unit can rotate in multiple directions to avoid the formation of eddies that cause stirring dead zones, effectively improving stirring efficiency and ensuring uniform temperature inside the crystallizer. At the same time, stirring the material allows the crystal particles to be uniformly suspended in the liquid phase, avoiding sedimentation and accumulation, ensuring that each crystal can come into contact with sufficient solute for growth. Stirring can also break up small agglomerates, improving crystal uniformity and purity.

[0045] The output components of the liquid addition assembly 2 include an annular liquid addition pipe 21 and a fixed connection pipe 22. The annular liquid addition pipe 21 is located in the inner cavity of the vessel support frame 1. Multiple liquid outlet end groups arranged in an annular array are installed on the inner side of the annular liquid addition pipe 21. The top of the annular liquid addition pipe 21 is connected to the bottom of the fixed connection pipe 22. The surface of the fixed connection pipe 22 is slidably connected to the top surface of the vessel support frame 1. It should be noted that a dynamic sealing structure is provided at the connection between the fixed connecting pipe 22 and the vessel support frame 1 to ensure the sealing performance of the vessel support frame 1; The liquid supply component of the liquid supply assembly 2 includes a liquid storage tank 23. A liquid supply pump 24 is installed above the liquid storage tank 23. The inlet end of the liquid supply pump 24 is connected to the side of the liquid storage tank 23. A telescopic hose 25 is detachably connected to the outlet end of the liquid supply pump 24. The end of the telescopic hose 25 away from the liquid supply pump 24 is detachably connected to the fixed connecting pipe 22.

[0046] Specifically, there are various detachable connection methods, such as threaded connection and snap-fit ​​connection, which are designed to replace the telescopic hose 25.

[0047] The inlet of the liquid pump 24 is connected to the lower part of the side of the liquid storage tank 23.

[0048] The liquid storage tank 23 has a U-shaped cross-section and is located on the outside of the mounting frame 4. The side of the liquid storage tank 23 closest to the vessel support frame 1 is connected to the outside of the vessel support frame 1 through multiple mounting brackets.

[0049] Furthermore, a one-way solenoid valve is installed at the outlet of the liquid adding pump 24 to control the opening and closing of the liquid adding component 2, so as to achieve automatic sealing after the liquid adding is completed.

[0050] The liquid storage tank 23, the liquid pump 24, the telescopic hose 25, the fixed connecting pipe 22, and the annular liquid filling pipe 21 are interconnected.

[0051] In this technical solution, the reaction liquid is uniformly added into the reactor support frame 1 through the liquid addition component 2.

[0052] In use, the liquid pump 24 pumps the reaction liquid in the storage tank 23 into the telescopic hose 25, then into the annular liquid addition pipe 21 through the fixed connecting pipe 22, and finally into the vessel support frame 1 through the liquid outlet end of the annular liquid addition pipe 21 to achieve uniform liquid addition.

[0053] Multiple cleaning scrapers 26 are connected to the outside of the annular liquid adding pipe 21. The side of the cleaning scraper 26 away from the annular liquid adding pipe 21 is in contact with the inner wall of the vessel support frame 1.

[0054] In this technical solution, the inner wall of the vessel support frame 1 is cleaned by the cleaning scraper 26 to prevent crystals from adhering to the inner wall of the vessel support frame 1.

[0055] During use, the cleaning scraper 26 moves in the same direction as the annular liquid addition pipe 21, thereby moving up and down along the axial direction of the reactor support frame 1. In this process, the inner wall of the reactor support frame 1 is cleaned to prevent crystal adhesion and facilitate smooth discharge from the crystal transfer reactor.

[0056] The upper end of the fixed connecting pipe 22 is connected to the output end of the lifting assembly 3. The lifting assembly 3 includes a lifting threaded shaft 31, which is rotatably disposed inside the mounting frame 4. One end of the lifting threaded shaft 31 is connected to the output end of the lifting power source 32, which is connected to the top of the mounting frame 4. Specifically, the top end of the lifting threaded shaft 31 is rotatably connected to the top surface of the mounting frame 4, and the top end of the lifting threaded shaft 31 is connected to the output end of the lifting power source 32.

[0057] The surface of the lifting threaded shaft 31 is threadedly connected to an active lifting plate 33. The active lifting plate 33 is slidably disposed in the inner cavity of the mounting frame 4. The top of the active lifting plate 33 is connected to a lifting connecting column 34. The top of the lifting connecting column 34 is connected to the bottom of the driven lifting plate 35. The driven lifting plate 35 is connected to the upper end of the fixed connecting pipe 22.

[0058] Specifically, the top of the active lifting plate 33 is connected to two symmetrically distributed lifting connecting columns 34, and the surface of the lifting connecting columns 34 is slidably connected to the top surface of the mounting frame 4.

[0059] The surface of the fixed connecting pipe 22 is fixedly connected to the driven lifting plate 35 through a through connection.

[0060] Furthermore, the inner wall of the mounting frame 4 is connected to multiple guide rails 36, and the surface of the guide rails 36 is slidably connected to the active lifting plate 33.

[0061] In this technical solution, the height of the liquid addition component 2 is adjusted by the lifting component 3, so that the reaction liquid can be added into the vessel support frame 1 from different heights, making the liquid addition more uniform.

[0062] In use, the lifting power source 32 drives the lifting threaded shaft 31 to rotate. When the lifting threaded shaft 31 rotates, it drives the active lifting plate 33 to move up or down along the guide rail 36, which in turn drives the lifting connecting column 34 and the driven lifting plate 35 to move in the same direction. This drives the fixed connecting pipe 22 to move in the same direction. When the fixed connecting pipe 22 moves, it drives the annular liquid filling pipe 21 to move in the same direction, thus adjusting the height of the annular liquid filling pipe 21.

[0063] The lifting threaded shaft 31, the active lifting plate 33, and the driven lifting plate 35 are respectively connected to the liquid processing mechanism for transmission. The liquid processing mechanism includes a first agitator 6. The bottom end of the lifting threaded shaft 31 is connected to the first stirrer 6 via a transmission, and the first stirrer 6 is driven to rotate by the rotation of the lifting threaded shaft 31.

[0064] Specifically, a rotating hole is provided on the side of the liquid storage tank 23 and the mounting frame 4 that are close to each other. The bottom end of the lifting threaded shaft 31 is rotatably connected to the side of the mounting frame 4 and the lifting assembly 3 that are close to each other through the rotating hole. A dynamic sealing structure is provided between the lifting threaded shaft 31 and the rotating hole opened in the liquid storage tank 23.

[0065] In this technical solution, the operation of the lifting component 3 drives the first stirrer 6 to rotate, thereby premixing the reaction liquid in the storage tank 23.

[0066] The liquid handling mechanism also includes a drive component, which includes a transmission assembly 7 and a second stirrer 8. The active lifting plate 33 and the driven lifting plate 35 are both connected to the transmission assembly 7. The transmission assembly 7 is connected to the second stirrer 8. The transmission assembly 7 is used to convert and transmit the force of the linear movement of the lifting threaded shaft 31 and the active lifting plate 33 to the second stirrer 8, thereby driving the second stirrer 8 to rotate.

[0067] The upper end of the second stirrer 8 is rotatably connected to the top surface of the liquid storage tank 23.

[0068] Specifically, both the first mixer 6 and the second mixer 8 consist of a central shaft and multiple mixing blades connected to the center.

[0069] More specifically, since the lifting assembly 3 has a U-shaped cross-section, the first stirrer 6 is located at the horizontal line of the U-shaped structure, and the second stirrer 8 is located at each of the two vertical lines of the U-shaped structure. The two second stirrers 8 are respectively connected to the lifting assembly 3 through the corresponding transmission assembly 7.

[0070] In this technical solution, the operation of the lifting component 3 drives the second stirrer 8 to rotate, thereby premixing the reaction liquid in the storage tank 23.

[0071] The transmission assembly 7 includes a movable rack 71, and two connecting bars 72 are connected to one side of the movable rack 71. The two connecting bars 72 are respectively connected to one side of the active lifting plate 33 and the driven lifting plate 35. A rotating rack 73 is meshed with one side of the movable rack 71, a first transmission part 74 is connected to one side of the rotating rack 73, a second transmission part 75 is connected to one side of the first transmission part 74, and the second transmission part 75 is connected to the upper end of the second stirrer 8.

[0072] Furthermore, a drive shaft is connected between the first drive unit 74 and the second drive unit 75, and the surface of the drive shaft is rotatably connected to the support side plate 76, which is connected to the top of the liquid storage tank 23.

[0073] Specifically, the first transmission part 74 and the second transmission part 75 are both composed of two meshing bevel gears. The two bevel gears at the first transmission part 74 are respectively connected to the rotating rack 73 and the transmission shaft, and the two bevel gears at the second transmission part 75 are respectively connected to the transmission shaft and the second stirrer 8.

[0074] The mounting frame 4 has a sliding opening on the side near the transmission component 7, and the connecting strip 72 is slidably connected to the side of the mounting frame 4 through the sliding opening.

[0075] It should be noted that, in order to protect the rotating rack 73, the first transmission part 74 and the second transmission part 75, a protective shell 77 is provided on their outer side. The protective shell 77 is connected to the outer side of the vessel support frame 1, the top of the liquid storage tank 23 and the outer side of the mounting frame 4 respectively. More specifically, the liquid pump 24 is mounted on top of the protective housing 77.

[0076] In addition, the liquid pump 24 can also be installed on the outside of the vessel support frame 1 or the liquid storage tank 23 via other connecting brackets.

[0077] The rotating rack 73 and a bevel gear of the first transmission part 74 are mounted on the same rotating shaft, the end face of which is rotatably connected to the outer side of the vessel support frame 1 or the inner wall of the protective shell 77.

[0078] In this technical solution, the force of the linear movement of the lifting threaded shaft 31 and the active lifting plate 33 is converted and transmitted to the second stirrer 8 through the lifting component 3, thereby driving the second stirrer 8 to rotate.

[0079] In use, the lifting power source 32 rotates to drive the first stirrer 6 to rotate, stirring and mixing the reaction liquid in the storage tank 23; When the active lifting plate 33 and the driven lifting plate 35 move, they drive the corresponding connecting column 72 to move in the same direction, thereby driving the moving rack 71 to move in the same direction. When the moving rack 71 moves, it drives the rotating rack 73 to rotate, which in turn drives the first transmission part 74 to rotate, thereby driving the second transmission part 75 to rotate. When the second transmission part 75 rotates, it drives the second stirrer 8 to rotate. The rotation of the second stirrer 8 stirs the reaction liquid in the liquid storage tank 23. In conjunction with the first stirrer 6, it can improve the mixing efficiency and reduce or even avoid the stirring dead zone.

[0080] It should be noted that the crystallization vessel can be equipped with multiple liquid addition units (except for the annular liquid addition pipe 21), and the multiple liquid addition units are respectively connected to the same annular liquid addition pipe 21.

[0081] Multiple liquid adding units can also be set directly, each liquid adding unit includes an annular liquid adding pipe 21, and the total stroke of multiple annular liquid adding pipes 21 is the longitudinal height of the inner cavity of the vessel support frame 1, or other linkage structures can be set to ensure that the strokes of multiple annular liquid adding pipes 21 do not interfere with each other when they are running.

[0082] The mixing unit includes an agitation component 9 and a transmission component 10. The agitation component 9 is connected to the output end of the stirring drive device 5 via the transmission component 10. The transmission component 10 is used to transmit the rotational force of the stirring drive device 5 to the agitation component 9, so that the rotation directions of each component of the agitation component 9 are different.

[0083] Furthermore, the distribution assembly 10 is disposed in the inner cavity of the partition frame 11, and the partition frame 11 is connected to the inner wall of the top surface of the vessel support frame 1, thereby protecting the distribution assembly 10.

[0084] In this technical solution, the transmission component 10 transmits the driving force of the stirring drive component 5 to the stirring component 9, which drives the stirring component 9 to run. The stirring component 9 stirs the material in the vessel support frame 1 so as to generate crystals.

[0085] The distribution assembly 10 includes a mounting shaft 101 and an outer sleeve 102. The outer sleeve 102 is rotatably sleeved on the surface of the mounting shaft 101. The surface of the mounting shaft 101 is rotatably connected to the top surface of the vessel support frame 1, and the surface of the outer sleeve 102 is rotatably connected to the bottom surface of the partition frame 11. The surface of the mounting shaft 101 is connected to an upper linkage component, and the surface of the outer sleeve 102 is connected to a lower linkage component. One end of both the upper and lower linkage components is connected to the linkage shaft 106. The two ends of the linkage shaft 106 are rotatably connected to the inner wall of the top surface of the lifting assembly 3 and the inner wall of the bottom surface of the partition frame 11, respectively.

[0086] Furthermore, the upper linkage component includes an upper gear 103, a transmission gear 104, and a linkage gear 105. The upper gear 103, transmission gear 104, and linkage gear 105 are sequentially meshed and connected. The upper gear 103 is connected to the surface of the mounting shaft 101, the linkage gear 105 is connected to the surface of the linkage shaft 106, and the transmission gear 104 is rotatably connected to the inner wall of the top surface of the lifting assembly 3. The lower linkage component includes a large gear 107 and a lower gear 108, which are meshed with each other. The large gear 107 is connected to the surface of the linkage shaft 106, and the lower gear 108 is connected to the surface of the outer sleeve 102.

[0087] In this technical solution, the rotational force of the stirring drive device 5 is transmitted to different parts of the stirring component 9 through the distribution component 10.

[0088] The stirring assembly 9 includes a central rotating shaft 91, the top end of which is connected to the bottom end of the mounting shaft 101, and a plurality of inner stirring frames 93 arranged in a ring array are connected to the lower surface of the central rotating shaft 91. Multiple outer stirring frames 94 arranged in a ring array are provided on the outer ring of the inner stirring frame 93, and the multiple outer stirring frames 94 are respectively connected to the surface of the outer sleeve 102.

[0089] Furthermore, a spiral stirring blade 92 is connected to the surface of the central rotating shaft 91.

[0090] The spiral stirring blade 92 rotates with the central rotating shaft 91 to perform spiral stirring on the material inside the central rotating shaft 91. The stirring method and stirring position of the spiral stirring blade 92 are different from those of the inner stirring frame 93 and the outer stirring frame 94, which can further improve the mixing efficiency of the material inside the vessel support frame 1.

[0091] In this technical solution, the material inside the vessel support frame 1 is fully stirred and mixed by the operation of the stirring component 9, so as to facilitate the preparation of α-type high-strength gypsum.

[0092] In use, the stirring drive device 5 drives the mounting shaft 101 to rotate, and the rotation of the mounting shaft 101 drives the upper gear 103 and the middle rotating shaft 91 to rotate respectively. When the central rotating shaft 91 rotates, it drives the spiral stirring blades 92 and multiple inner stirring frames 93 to rotate. When the upper gear 103 rotates, it drives the transmission gear 104 to rotate, which in turn drives the linkage gear 105 to rotate, which in turn drives the linkage shaft 106 to rotate. When the linkage shaft 106 rotates, it drives the large gear 107 to rotate, which in turn drives the lower gear 108 to rotate. When the lower gear 108 rotates, it drives the outer sleeve 102 to rotate, which in turn drives multiple outer stirring frames 94 to rotate.

[0093] In addition, the different diameters of the upper gear 103 and the lower gear 108 result in different rotational speeds of the mounting shaft 101 and the outer sleeve 102, which in turn causes a difference in the stirring speed of the inner stirring frame 93 and the outer stirring frame 94. This makes it easier to mix the materials in the vessel support frame 1 and facilitates the formation of crystals.

[0094] It should be noted that the upper gear 103 and the lower gear 108, etc., drive the installation shaft 101 and the outer sleeve 102 to rotate in opposite directions, thereby making the inner stirring frame 93 and the outer stirring frame 94 rotate in opposite directions.

[0095] The stirring drive device 5 and the lifting power source 32 are motor units or other devices that can output rotational kinetic energy.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
