Description

Technical Field

[0001] The invention relates to the technical field of accelerator production equipment, in particular to a stirring device for producing an early high-strength alkali-free accelerator. Background Art

[0002] Early high-strength alkali-free accelerator is a chemical additive widely used in construction projects. It is mainly used to accelerate the setting and hardening process of concrete and improve the early strength of concrete. Compared with traditional accelerators, early high-strength alkali-free accelerator does not contain alkaline components, so it will not have negative effects such as alkali-aggregate reaction on concrete during use, which helps to ensure the long-term stability and durability of concrete structures.

[0003] Aluminum sulfate and diethanolamine are generally used in the production of quick-setting agents. During the production process, they are heated and stirred to prevent the reaction solution in the reactor from being incompletely dissolved. In the process of mass production, such as the one-time production of 5 tons or 10 tons, aluminum sulfate and diethanolamine need to be added in batches for multiple times to make the solution more viscous. Aluminum sulfate and diethanolamine are less likely to be completely dissolved, which makes the inner wall of the reactor very easy to stick. During continuous production, the materials adhering to the inner wall will not be cleaned up, and will only be cleaned up after the production is completed, causing the sticky materials to harden and solidify. The method of using clean water and a stirring shaft cannot clean up the solidified and hardened materials. At this time, people usually enter the reactor manually for processing. This method is not only troublesome, but also has certain safety hazards. Summary of the invention

The stirring mechanism is assembled in the reactor 100, and is used to stir and heat the reaction solution in the reactor 100. The cleaning mechanism 300 is assembled on the reactor 100, and is used to clean the inner wall of the reactor 100, and can shrink and deform when cleaning is not required. By setting the cleaning mechanism 300, the cleaning mechanism 300 can be retracted in the reactor 100 when not in use, reducing the occupation and impact on the stirring space; when in use, the inner wall of the reactor 100 can be quickly cleaned, and the solidified and hardened adhesions can also be cleaned. It can be applicable to reactors 100 of different structures, and the cleaning efficiency is high, and the safety hazards caused by manual cleaning can be avoided.

[0029] In this embodiment, the reactor 100 includes a reactor body 1 and a reactor cover 11. The reactor cover 11 is fixedly installed in the reactor body 1 by bolts. The stirring mechanism is partially in the reactor body 1 and partially on the reactor cover 11, which is used to stir and heat the reaction solution added to the reactor 100. The cleaning mechanism 300 is partially in the reactor body 1 and partially on the reactor cover 11, so that the part located in the reactor body 1 can clean the inner wall of the reactor 100 of different structures when working. The reactor cover 11 has a feed port 12 for adding materials. The bottom of the reactor body 1 has a discharge pipe 13 for discharging the accelerating agent after the reaction is completed.

[0030] In this embodiment, if Figure 2 As shown, the kettle cover 11 includes a fixed part and a rotating part 14, the fixed part is fixedly installed on the kettle body 1 by bolts, and the rotating part 14 is rotatably assembled on the fixed part through the step of the fixed part, and the stirring mechanism and the cleaning mechanism 300 are both installed on the rotating part 14. On the one hand, it provides a mounting basis, and on the other hand, when the cleaning mechanism 300 is working, it can drive the stirring mechanism and the rotating part 14 to rotate together; when the cleaning mechanism 300 is not working, the stirring mechanism can work normally to stir the reaction materials.

[0031] In some embodiments, Figure 2 As shown, the stirring mechanism includes at least one stirring structure 200. In this embodiment, two stirring structures 200 are provided, and the two stirring structures 200 are respectively provided on both sides of the cleaning mechanism 300, so as to stir and heat the materials in the reactor 100 more evenly.

[0032] In this embodiment, the two stirring structures 200 are the same, and one of them is used as an example for description below. The stirring structure 200 includes a first power source 210, a stirring member, and a heating member 240. The stirring member is rotatably assembled in the reactor 100, and the heating member 240 is fixedly arranged on the stirring member. The first power source 210 is fixedly assembled on the rotating part 14 and is transmission-connected with the stirring member. By arranging the heating member 240 on the stirring member, heating can be performed during the stirring process, so that the reaction solution in the reactor 100 is heated more fully.

[0033] In this embodiment, the first power source 210 can be set as a servo motor, a reduction motor, and a suitable motor can be selected according to actual conditions. The stirring member includes a stirring shaft 220 and a stirring blade 230. The stirring shaft 220 is rotatably mounted on the kettle cover 11 and is connected to the output shaft of the first power source 210 through a coupling. The stirring blade 230 is staggered on the stirring shaft 220, and the heating element 240 is fixedly mounted on the surface of each stirring blade 230, so that the temperature of the reaction solution is more easily controlled between 40-45°C.

[0034] In this embodiment, the heating element 240 is an electric heating plate, an electric heating sheet, etc., and a suitable heating device can be selected according to actual conditions.

[0035] In some embodiments, Figure 2-11 As shown, the cleaning mechanism 300 includes a rotating unit 30, a transmission unit 40 and a cleaning unit 50. The rotating unit 30 is assembled in the reactor 100, and is used to drive the transmission unit 40 and the cleaning unit 50 to rotate. The transmission unit 40 is assembled on the rotating unit 30. When in use, it can control the cleaning unit 50 to deform, which can not only clean the inner wall of the reactor 100, but also adapt to different reactors 100; when not in use, it can shrink to reduce the occupied space in the reactor 100 to avoid affecting the addition of materials. The cleaning unit 50 is assembled on the transmission unit 40, and is used to clean the inner wall of the reactor 100.

[0036] In some embodiments, Figure 2-6 As shown, the rotating unit 30 includes a rotating shaft 31, a mounting sleeve 32, a second power source 33 and a reciprocating structure. The rotating shaft 31 is rotatably mounted in the reactor 100, the mounting sleeve 32 is slidably mounted on the rotating shaft 31, the transmission unit 40 is mounted on the mounting sleeve 32, and the cleaning unit 50 is mounted on the transmission unit 40. The second power source 33 is transmission-connected with the rotating shaft 31 to drive the rotating shaft 31 to rotate. When the rotating shaft 31 rotates, the mounting sleeve 32 can be driven to rotate. The reciprocating structure is assembled on the second power source 33 and fixedly connected with the mounting sleeve 32, so that when the reciprocating structure is working, it can drive the mounting sleeve 32 to rise and fall on the rotating shaft 31, and can drive the transmission unit 40 and the cleaning unit 50 to rise and fall, and cooperate with the rotation of the mounting sleeve 32 to drive the transmission unit 40 and the cleaning unit 50 to rotate, so as to achieve effective cleaning of the inner wall of the reactor 100.

[0037] In this embodiment, the reciprocating structure, the rotating shaft 31 and the mounting sleeve 32 can rotate synchronously, so that the rotation of the rotating shaft 31 will not affect the operation of the reciprocating structure.

[0038] In this embodiment, at least two slide grooves 311 are evenly spaced apart on the outer surface of the rotating shaft 31, preferably four, and a slider 322 is correspondingly provided on the inner wall of the mounting sleeve 32. The slider 322 is located in the slide groove 311. On the one hand, the mounting sleeve 32 can slide on the rotating shaft 31, and on the other hand, the rotating shaft 31 can drive the mounting sleeve 32 to rotate.

[0039] In order to remove the materials adhering to the rotating shaft 31 and the slide groove 311, the end face of each slider 322 is set as an inclined surface, and an arc-shaped scraper 321 is set at the bottom of the mounting sleeve 32, so that when the mounting sleeve 32 moves on the rotating shaft 31, the materials adhering to the rotating shaft 31 and the slide groove 311 can be removed.

[0040] In this embodiment, if Figure 2-3 As shown, the second power source 33 includes a ring gear 331, a gear 332 and a motor 333. The ring gear 331 is fixedly mounted on the rotating shaft 31 through a spline, the gear 332 is meshed with the ring gear 331, and the output shaft of the motor 333 is fixedly connected with the gear 332 through a spline, so that when the motor 333 is working, it can drive the gear 332 to rotate, the rotation of the gear 332 drives the ring gear 331 to rotate, and the rotation of the ring gear 331 drives the rotating shaft 31 to rotate. In actual situations, the output shaft of the motor 333 can also be directly connected to the rotating shaft 31 through a coupling.

[0041] In this embodiment, the rotating unit 30 also includes a transmission frame 38, the middle part of which is rotatably connected to the rotating shaft 31, and is used to provide a more stable support for the rotating shaft 31. A cover 37 is also installed on the rotating part 14, which is used to cover the position of the ring gear 331, the gear 332 and the rotating shaft 31 to prevent the entry of foreign matter. Both ends of the transmission frame 38 are fixedly connected to the fixed part by bolts, the cover 37 is fixedly connected to the transmission frame 38 by two connecting rods 371, and the motor 333 is fixedly installed on the cover 37 by a flange. When the motor 333 is working, the rotating shaft 31 is rotated, so that the transmission unit 40 and the cleaning unit 50 can be driven to rotate together in the reactor 100, so as to clean the inner wall of the reactor 100.

[0042] In this embodiment, if Figure 3-5 As shown, the second power source 33 further includes a rotating disk 334, a connecting flange 335 and a clamping block 336. The clamping block 336 is symmetrically arranged on the rotating disk 334. The clamping block 336 is engaged with two of the chute 311 on the rotating shaft 31, so that the rotating disk 334 can rotate together with the rotating shaft 31. The upper end of the connecting flange 335 is fixedly arranged on the rotating disk 334, and the lower end of the connecting flange 335 is fixedly connected to the rotating part 14 by bolts, so that when the rotating shaft 31 rotates, the rotating disk 334 can rotate, and when the rotating disk 334 rotates, it can drive the rotating part 14 to rotate on the fixed part, and then drive the two stirring structures 200 to rotate together, so that when the transmission unit 40 and the cleaning unit 50 rotate and clean in the reactor 100, the stirring structure 200 will not block the rotation of the transmission unit 40 and the cleaning unit 50.

[0043] In this embodiment, if Figure 3-4 As shown, the reciprocating structure is assembled on the rotating disk 334 so that the reciprocating structure can rotate synchronously with the rotating shaft 31. The reciprocating structure is arranged in two groups, and the two groups of reciprocating structures are symmetrically arranged and correspond to the slide grooves 311 respectively. The two groups of reciprocating structures are the same, and one group is taken as an example for description as follows: The reciprocating structure includes a driving source 342 and an actuator. The driving source 342 is fixedly assembled on the rotating disk 334, one end of the actuator is fixedly connected to the mounting sleeve 32, and the other end is transmission-connected to the driving source 342. Through the cooperation between the driving source 342 and the actuator, the mounting sleeve 32, the transmission unit 40 and the cleaning unit 50 can be driven to rise and fall on the rotating shaft 31, thereby effectively cleaning the inner wall of the reactor 100.

[0044] In one embodiment, the driving source 342 can be set as a motor, and the actuator includes a bracket 34, a winch 341 and a wire rope 343. The bracket 34 is fixedly mounted on the rotating disk 334 by bolts, and the winch 341 is rotatably mounted on the bracket 34. One end of the wire rope 343 is wound on the winch 341, and the other end is fixedly connected to the slider 322, so that when the motor is working, it can drive the wire rope 343 to wind or loosen on the winch 341, thereby driving the installation sleeve 32 to rise and fall along the rotating shaft 31. In this working mode, in order to make the wire rope 343 always located in the slide groove 311, a clamp can be set on the rotating shaft 31, and the wire rope 343 passes over the clamp and winds around the winch 341. In this working mode, in order to make the installation sleeve 32 have enough weight to drop, a counterweight block can be set at the bottom of the installation sleeve 32. A spring 36 may also be sleeved on the rotating shaft 31, one end of the spring 36 abuts against the top of the mounting sleeve 32, and the other end abuts against the bottom of the rotating disk 334. When the mounting sleeve 32 does not descend, the transmission unit 40 and the cleaning unit 50 are not working, and the spring 36 is in a compressed state. By controlling the length of the steel wire rope 343, the descending height of the mounting sleeve 32 is controlled. At this time, the power for the mounting sleeve 32 to descend depends on the force of the spring 36 to restore the deformation, and the power for the mounting sleeve 32 to rise depends on the pulling of the steel wire rope 343, and finally the spring 36 is compressed. A suitable control method may also be selected according to actual conditions.

[0045] In another embodiment, the driving source 342 is also configured as a motor, and the actuator is configured as a gear 332 and a rack. The rack is located in the slide slot 311, and one end of the rack is fixedly connected to the slider 322 by bolts. The output shaft of the motor 333 is fixedly connected to the gear 332, and the gear 332 is meshed with the rack, so that when the motor is working, it can drive the gear 332 to rotate, and the rotation of the gear 332 drives the rack to move, and the movement of the rack drives the installation sleeve 32 to move along the rotating shaft 31, thereby driving the transmission unit 40 and the cleaning unit 50 to rise and fall. In actual situations, the rise and fall of the installation sleeve 32 can also be controlled by setting an electric telescopic rod, and other devices that can achieve movement can also be selected according to actual conditions.

[0046] In some embodiments, Figure 2-3 , Figure 6 , Figure 8-9As shown, the transmission unit 40 includes at least one transmission assembly, which is assembled on the rotating unit 30 and is used to drive the cleaning unit 50 to shrink and deform. In this embodiment, the transmission assembly is arranged in two groups, and the two groups of transmission assemblies are symmetrically arranged and have the same structure to improve the cleaning effect.

[0047] In this embodiment, one of the groups is taken as an example for description, and the transmission assembly includes a first transmission structure 41 and a second transmission structure 42. The first transmission structure 41 and the second transmission structure 42 are both fixedly assembled on the rotating unit 30, and are used to synchronously or / and asynchronously drive the cleaning unit 50 to move, so that the cleaning unit 50 can adapt to the cleaning of the inner wall of the reactor 100 with different structures.

[0048] In this embodiment, if Figure 4-8 As shown, the first transmission structure 41 and the second transmission structure 42 have the same structure. The first transmission structure 41 is taken as an example for description below. The first transmission structure 41 includes a housing 411, a third power source, a sliding rod 413 and an end cover 412. The housing 411 is fixedly assembled on the mounting sleeve 32, the end cover 412 is assembled on the free end of the housing 411, and the sliding rod 413 is slidably arranged in the housing 411 and passes through the end cover 412. The third power source is connected to the sliding rod 413 for transmission, and is used to control the movement of the sliding rod 413. The cleaning unit 50 is movably assembled at the free end of the sliding rod 413 of the first transmission structure 41 and the second transmission structure 42. Through the movement of the sliding rod 413, the cleaning unit 50 can be driven to move away from, approach or tilt relative to the housing 411, so that the cleaning unit 50 can adjust the posture of the cleaning unit 50 according to different inner walls of the reactor 100 when in use; when not in use, it can be folded near the housing 411 to reduce the occupied space in the reactor 100.

[0049] In this embodiment, sealing rings are installed between the end cover 412 and the housing 411 and between the end cover 412 and the sliding rod 413 to prevent impurities from entering and improve the sealing performance.

[0050] In one embodiment, the third power source can be set as an electric telescopic rod, which is fixedly installed at the contact position between the housing 411 and the mounting sleeve 32 by bolts, so that the output end of the electric telescopic rod is fixedly connected to one end of the sliding rod 413, so that when the electric telescopic rod is working, it can drive the sliding rod 413 to move, and the movement of the sliding rod 413 drives the cleaning unit 50 to move. In actual situations, other devices with telescopic functions can also be selected, such as cylinders, etc.

[0051] In another embodiment, the third power source can be set as a high-pressure gas source. In this way, an air duct 354 is arranged between the shell 411 in the first transmission structure 41 and the second transmission structure 42 and the mounting sleeve 32, and the mounting sleeve 32 is provided with a first joint 35 at the top of the air duct 354, and a second joint 351 is arranged on the rotating disk 334. The first joint 35 and the second joint 351 are connected by a bellows 353 or two sleeves that can be relatively slidably sealed. The second joint 351 is connected to an external high-pressure gas source or an air compressor, and a reset spring is arranged between the sliding rod 413 and the end cover 412. At this time, under the action of the high-pressure gas, the sliding rod 413 can be driven to move in the shell 411, thereby driving the cleaning unit 50 to move, and can be reset under the action of the reset spring.

[0052] In this embodiment, when a high-pressure gas source is used, the second joints 351 on the two sets of transmission components are connected through the pipeline 352, so that a high-pressure gas source can be used as power. At this time, the high-pressure gas source generation device can be installed on the rotating disk 334, or it can be connected to the high-pressure gas source installed in the outside through a gas pipe wound around the rotating shaft 31 for multiple turns. Through multiple turns of winding, the gas pipe can be prevented from affecting the rotation of the rotating shaft 31. When the transmission unit 40 and the cleaning unit 50 rotate, they can rotate 180° forward and then reverse 180° to reduce the impact on the reciprocating structure and the third power source.

[0053] In some embodiments, Figure 6 , Figure 8-9 , Figure 11-12 As shown, the cleaning unit 50 includes a connecting structure, an adjusting structure, a first cleaning brush 55 and a scraping structure 56. The connecting structure is hinged at the free end of the sliding rod 413, and is used to passively adjust the position of the cleaning unit 50 according to the movement of the transmission unit 40. The first cleaning brush 55 and the second scraping structure 56 are respectively assembled on both sides of the adjusting structure, and the adjusting structure is assembled on the connecting structure, and is used to adjust the positions of the first cleaning brush 55 and the scraping structure 56 according to the condition of the inner wall of the reactor 100, so as to achieve cleaning of the inner wall of the reactor 100 in different conditions with high efficiency.

[0054] In this embodiment, the connecting structure includes a first connecting structure 51 and a second connecting structure 52. The first connecting structure 51 is hinged on the sliding rod 413 of the first transmission structure 41, and the second connecting structure 52 is hinged on the sliding rod 413 of the second transmission structure 42. The adjusting structure is rotatably installed between the first connecting structure 51 and the second connecting structure 52.

[0055] In this embodiment, if Fig.11As shown, the first connection structure 51 and the second connection structure 52 are the same. The first connection structure 51 is taken as an example for explanation below: the first connection structure 51 includes a hinge block 510 and a mounting seat 511. One end of the hinge block 510 is hinged to the free end of the sliding rod 413, and the other end is fixedly connected to the mounting seat 511. The adjustment structure is assembled between the two mounting seats 511. The first connection structure 51 is hinged to the sliding rod 413 of the first transmission structure 41, and the second connection structure 52 is hinged to the sliding rod 413 of the second transmission structure 42, thereby driving the posture of the adjustment structure, the first cleaning brush 55 and the scraping structure 56 to change. For example, it can be vertical, or it can be tilted outward, etc. (such as Figure 8-9 As shown) the inner wall of the side of the reactor 100 can adapt to the barrel-shaped structure and the conical structure.

[0056] In this embodiment, if Figure 9-12 As shown, the adjustment structure includes an adjustment column 53, a first connecting shaft 532, a second connecting shaft 531 and a driving structure 54. The first connecting shaft 532 is fixedly connected to the top of the adjustment column 53 and rotates to penetrate into the mounting seat 511 of the first connecting structure 51. The second connecting shaft 531 is fixed to the mounting seat 511 of the second connecting structure 52 and rotates to penetrate into the adjustment column 53, so that the adjustment column 53 can rotate. The first cleaning brush 55 is fixedly installed on one side of the adjustment column 53 by bolts, and the scraping structure 56 is fixedly installed on the other side of the adjustment column 53 by bolts. The driving structure 54 is in transmission connection with the first connecting shaft 532, so that when the driving structure 54 is working, the positions of the first cleaning brush 55 and the scraping structure 56 can be fixed or converted.

[0057] In this embodiment, the scraping structure 56 is provided with a scraper, and the scraper is fixedly mounted on one side of the adjustment column 53 through a scraper seat.

[0058] In this embodiment, the driving structure 54 includes a connecting frame, a waterproof motor 543, a turbine 533 and a worm 545. One end of the connecting frame is sleeved on the free end of the sliding rod 413 and positioned by two limit clamps 544. The waterproof motor 543 is fixedly mounted on the other end of the connecting frame by bolts. A receiving groove and a notch are provided on the mounting seat 511 of the first connecting structure 51. The receiving groove and the notch are connected. The first connecting shaft 532 is located in the receiving groove. The turbine 533 is fixedly mounted on the first connecting shaft 532 by splines. One end of the worm 545 is located in the notch and meshes with the turbine 533. The other end is connected to the output shaft of the waterproof motor 543 by a coupling. When the waterproof motor 543 is working, it can drive the turbine 533 and the worm 545 to rotate, thereby driving the first connecting shaft 532 to rotate, and then driving the adjusting column 53 to rotate, so as to achieve the position change of the first cleaning brush 55 and the scraping structure 56. Here, the transmission method of the turbine 533 and the worm 545 can achieve self-locking, thereby preventing the first cleaning brush 55 and the scraping structure 56 from rotating on their own during the cleaning process, thereby preventing the cleaning effect from being affected.

[0059] In this embodiment, if Fig.12 As shown, the connecting frame includes a main body 540 and a rotating frame 541. The upper end of the main body 540 is sleeved on the free end of the sliding rod 413 and is positioned by two limit clamps 544. The rotating frame 541 is sleeved on the main body 540, and the rotating frame 541 and the main body 540 are rotatably connected by a rotating pin 542, so that the rotating frame 541 and the main body 540 can rotate relative to each other, so that when the adjusting column 53 and the sliding rod 413 of the first connecting structure 51 and the sliding rod 413 of the second connecting structure 52 are in an inclined state, the waterproof motor 543 can adaptively adjust the angle.

[0060] In this embodiment, in order to realize the installation of the turbine 533 and the worm 545, the mounting seat 511 of the first connecting structure 51 is made into a two-section type, the receiving groove and the notch are located in the upper section, and the mounting seat lower section 512 is made into two halves. When realizing the installation of the worm 545, a corresponding limit block is provided at the notch. In order to prevent debris from entering the notch, an arc sheet is also provided outside the notch.

[0061] In another embodiment, Figure 9-10 As shown, the cleaning unit 50 also includes a second cleaning brush 60 , which is movably mounted on the housing 411 of the second transmission structure 42 , namely, located at the lower part of the mounting sleeve 32 , for cleaning the bottom inner wall of the barrel-shaped reactor 100 .

[0062] In this embodiment, one end of the second cleaning brush 60 is located at the bottom of the mounting sleeve 32 and is redundant, and the other end is connected to the sliding rod 413 of the second transmission structure 42 through the fixing frame 61. When the fixing frame 61 is connected to the sliding rod 413, they are also positioned by the limiting clamp 544. The middle part of the second cleaning brush 60 has a sliding groove, and a plurality of limiting nails 62 are fixed on the housing 411 of the second transmission structure 42. The limiting nails 62 pass through the sliding groove and slide with the second cleaning brush 60, so that when the sliding rod 413 of the second transmission structure 42 moves, it can drive the second cleaning brush 60 to move, so as to clean the bottom inner wall of the barrel-shaped reactor 100.

[0063] In this embodiment, the brush bottom of the second cleaning brush 60 is made of a flexible material, which is beneficial to the movement of the second cleaning brush 60 and prolongs the service life of the second cleaning brush 60 .

[0064] In this embodiment, when the cleaning unit 50 is not in use, it can be located above the liquid surface of the reactor 100. When in use, the accelerator in the reactor 100 has been completely discharged, thereby reducing the damage of the accelerator to the first cleaning brush 55 and the second cleaning brush 60. Of course, the material of the cleaning brush can also be replaced with an acid-resistant, alkali-resistant, and high-temperature resistant material so that the first cleaning brush 55 and the second cleaning brush 60 can be used when the accelerator is located in the reactor 100.

[0065] When the first cleaning brush 55 and the second cleaning brush 60 are lowered from the liquid surface to clean the inner wall of the reactor 100, the two stirring structures 200 need to rotate at the same time to avoid the two stirring structures 200 blocking the cleaning brushes. During the descent process, the angles of the stirring blades 230 in the two stirring structures 200 can be adjusted to avoid blocking the descent of the cleaning mechanism 300. This adjustment method can be adjusted by conventional parameters or by visual inspection. When visually inspecting, it is necessary to start the observation window at the position corresponding to the reactor cover 11, etc.
