[0001] This utility model relates to the field of grouting repair material technology, specifically a blast furnace grouting repair material mixing device. Background Technology

[0002] The blast furnace grouting repair material mixing device is a special equipment used for mixing blast furnace grouting repair materials;

[0003] The blast furnace grouting repair material has a certain degree of adhesion. Therefore, when the material is discharged, some of it will adhere to the inner wall of the mixing drum and the transition discharge shell, resulting in material waste and poor working quality of the mixing device.

[0004] Meanwhile, after the material is scraped off the inner wall, because the amount of this material is relatively small, and the fluidity of the blast furnace grouting repair material is poor, this material cannot flow to the discharge pipe in time for discharge, resulting in low working efficiency of the mixing device. Utility Model Content

[0005] To address the above problems, this utility model provides a blast furnace grouting repair material mixing device, which solves the aforementioned issues.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a blast furnace grouting repair material mixing device, including a fixed frame and a control cabinet connected to the fixed frame, a transition discharge shell connected to the top of the fixed frame, a mixing cylinder connected to the top of the transition discharge shell, an installation frame connected to the top of the mixing cylinder, and a motor connected to the top of the installation frame.

[0007] The output end of the motor is connected to a rotating shaft, and two mounting rings are connected to the outside of the rotating shaft. An agitator is connected to the outside of the mounting rings, and a scraper is connected to one end of the agitator. One side of the scraper overlaps with the inner wall of the mixing drum.

[0008] The rotating shaft passes through the inner bottom surface of the stirring drum. A connecting shaft is connected to the bottom of the rotating shaft. Two rotating rings are connected to the outside of the connecting shaft. Several connecting rods are connected to one side of one of the rotating rings. A straight scraper is connected to one end of each connecting rod.

[0009] A stirring rod is connected to one side of the straight scraper, a guide plate is connected to one side of the straight scraper, and a scraping strip is connected to one side of the guide plate.

[0010] Preferably, one side of the guide ramp is connected to several turbulence-inducing inclined rods, and the angle between the scraper strip and the guide ramp is an obtuse angle.

[0012] Preferably, the first helical blade is disposed inside the mixing drum, and the second helical blade is disposed inside the transition discharge shell.

[0013] Preferably, the bottom of the mixing drum is connected to two feed pipes.

[0014] Preferably, the bottom of the transition discharge shell is connected to a discharge pipe, and one end of the discharge pipe is connected to a discharge pipe.

[0015] Preferably, the discharge pipe is externally connected to several fixing blocks, and one side of each fixing block is connected to the top of the fixing frame.

[0016] Preferably, one side of one of the fixed blocks is connected to a grouting pump, the output end of the grouting pump is connected to a discharge pipe, and a flow meter is connected to one side of the discharge pipe.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This application uses a first spiral blade in combination with a scraper and a second spiral blade in combination with a straight scraper to prevent the grouting repair material from adhering to the inner wall of the mixing drum and the transition discharge shell during mixing and discharge. This avoids material waste and solves the problem that the grouting repair material has a certain degree of adhesion, and some material will adhere to the inner wall of the mixing drum and the transition discharge shell during the mixing and discharge process, resulting in material waste. This is beneficial to improving the working quality of the mixing device.

[0019] 2. This application uses a guide plate in conjunction with a scraper to guide the material scraped off the inner wall, and the obtuse angle between the scraper and the guide plate carries the material to the discharge pipe, which facilitates the discharge of the material. This solves the problem that the material scraped off the inner wall by the mixing device is not easy to discharge, and helps to improve the working efficiency of the mixing device.

[0020] 3. By using scrapers and straight scrapers in combination, this application also facilitates the washing and cleaning of the mixing device after the grouting and repair material mixing and discharge work is completed.

Detailed Implementation

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] Please see Figures 1 to 6 A blast furnace grouting repair material mixing device includes a fixed frame 1 and a control cabinet 2 connected to the fixed frame 1. The control cabinet 2 is used to control the operation of the mixing device and the operation of the discharge pipe 23. The control cabinet 2 is a known technology, and those skilled in the art can and should understand its specific functions and structure, so it will not be described in detail here. The top of the fixed frame 1 is connected to a transition discharge shell 3, the top of the transition discharge shell 3 is connected to a mixing drum 4, the top of the mixing drum 4 is connected to a mounting frame 6, and the top of the mounting frame 6 is connected to a motor 7. The transition discharge shell 3 is used to receive and temporarily store the material mixed by the mixing drum 4. The semi-open structure makes it convenient to observe the remaining material inside and to check and intervene in the discharge situation. The mixing drum 4 is used to fully mix the repair material to ensure the uniformity of the material, and after the material is mixed, it discharges the material to the transition discharge shell 3 below for temporary storage.

[0030] It should be further explained that after the materials in the mixing drum 4 are mixed, they are discharged into the transition discharge shell 3 through the discharge pipe 5. At this time, the materials will be temporarily stored in the transition discharge shell 3. Then, the personnel can continue to put the materials into the mixing drum 4 to continue the mixing work.

[0031] This allows for simultaneous mixing and discharging. Specifically, the material is mixed in the mixing drum 4, and the material can be discharged from the transition discharge shell 3. It is not necessary to discharge all the mixed material before continuing the mixing process.

[0032] The output end of the motor 7 is connected to a rotating shaft 8. Two mounting rings 9 are connected to the outside of the rotating shaft 8. An agitator 11 is connected to the outside of the mounting rings 9. A scraper 12 is connected to one end of the agitator 11. One side of the scraper 12 overlaps with the inner wall of the mixing drum 4.

[0033] The rotating shaft 8 passes through the inner bottom surface of the stirring drum 4. The bottom of the rotating shaft 8 is connected to a connecting shaft 13. The outside of the connecting shaft 13 is connected to two rotating rings 14. One side of one of the rotating rings 14 is connected to several connecting rods 16. One end of the connecting rod 16 is connected to a straight scraper 17.

[0034] When the stirring device is working, it is divided into two areas: the inside of the stirring drum 4 and the inside of the transition discharge shell 3. The output end of the motor 7 drives the rotating shaft 8 to rotate. At this time, the rotating shaft 8 will drive the mounting ring 9 and the first spiral blade 10 to rotate, and at the same time drive the stirring frame 11 and the scraper 12 to rotate.

[0035] It should be further explained that when the first spiral blade 10 rotates, it works with the stirring frame 11 to stir and mix the material inside the mixing drum 4. Moreover, this stirring can push the material to move along the axial and radial directions, forming a complex spatial motion trajectory, so that different components of the material can be fully intermingled and mixed, improving uniformity, and allowing coarse and fine aggregates, powders, additives, etc. to be evenly distributed.

[0036] When the material in the mixing drum 4 is stirred and mixed and discharged to the transition discharge shell 3, the material will adhere to the inner wall of the mixing drum 4 due to its adhesiveness, resulting in incomplete discharge and material waste. Therefore, during discharge, the rotating shaft 8 continues to rotate, which will drive the stirring frame 11 and scraper 12 to rotate.

[0037] At this time, the bottom of the stirring frame 11 is in contact with the inner bottom surface of the mixing drum 4, which can help the material to be discharged into the discharge pipe 5. Moreover, when the scraper 12 rotates, it can scrape the inner wall of the mixing drum 4, so that the material on the inner wall of the mixing drum 4 falls to the inner bottom surface of the mixing drum 4. This, together with the stirring frame 11, helps to discharge the material, thus avoiding the waste of material caused by some material adhering to the inner wall of the mixing drum 4 when the grouting repair material is discharged.

[0038] A stirring rod 18 is connected to one side of the straight scraper 17, a guide plate 19 is connected to one side of the straight scraper 17, and a scraper strip 20 is connected to one side of the guide plate 19.

[0039] Of course, when the rotating shaft 8 rotates, it penetrates the inner bottom surface of the mixing drum 4, so that the rotating shaft 8 will also drive the connecting shaft 13 to rotate. The connecting shaft 13 will drive the rotating ring 14 and the second spiral blade 15 to rotate, and at the same time drive the connecting rod 16 and the straight scraper 17 to rotate.

[0040] Specifically, during rotation, the straight scraper 17 will also drive the stirring rod 18, the guide plate 19, and the turbulence rod 21 to rotate. Therefore, when the well-mixed material falls into the transition discharge shell 3 for temporary storage and discharge, it is also necessary to keep stirring. The second spiral blade 15, in conjunction with the stirring rod 18, stirs the material in the transition discharge shell 3.

[0041] To prevent segregation during stirring, the flow-disrupting inclined rod 21 can disrupt the material flow trajectory, creating a more complex flow field in the transition discharge shell 3. This allows the coarse and fine aggregates and binders to fully contact and mix, improving uniformity and preventing segregation. The coarse aggregate in the blast furnace grouting repair material has a high density and tends to sink during stirring. The disturbance generated by the flow-disrupting inclined rod 21 can hinder the sinking of the coarse aggregate, keeping it suspended and dispersed in the slurry, thus making the slurry mix more uniformly.

[0042] It is important to note that because the material storage time in the transition discharge shell 3 is inconsistent, and sometimes the storage time is relatively long, some turbulence measures need to be taken to prevent segregation. However, the stirring time of the material in the mixing drum 4 is fixed, and the stirring and mixing work is completed before segregation occurs. Therefore, the material in the mixing drum 4 does not require turbulence measures.

[0043] When the material is discharged from the transition discharge shell 3, the straight scraper 17, in conjunction with the guide inclined plate 19, can scrape off the material adhering to the inner wall of the transition discharge shell 3. It should be noted that when the material on the inner wall is scraped off, it will be guided by the guide inclined plate 19 to the inner bottom surface of the transition discharge shell 3. At this time, the scraper 20 and the guide inclined plate 19 cooperate, and the included angle between them will drive the scraped material to move. Since the discharge pipe 22 is set on the rotation path of the included angle, the scraper 20 and the guide inclined plate 19 can cooperate to discharge the scraped material into the discharge pipe 22, thereby improving the working efficiency of the stirring device.

[0044] It should be further added that after using the mixing device, personnel need to rinse and clean it. When personnel rinse the mixing device, the inner walls of the mixing drum 4 and the transition discharge shell 3 can be cleaned by the stirring frame 11, scraper 12, straight scraper 17, guide inclined plate 19, and scraper strip 20. This solves the problem that it is inconvenient for personnel to clean the mixing device after use, and helps to improve the practical performance of the mixing device.

[0045] Several turbulence-inducing inclined rods 21 are connected to one side of the guide inclined plate 19. Turbulence-inducing columns are provided on the outside of the turbulence-inducing inclined rods 21. The turbulence-inducing columns rotate outside the turbulence-inducing inclined rods 21. The turbulence-inducing inclined rods 21 and the turbulence-inducing columns work together to turbulent the material when it is being stirred. The angle between the scraper strip 20 and the guide inclined plate 19 is an obtuse angle.

[0046] A first helical blade 10 is connected between the two mounting rings 9, and a second helical blade 15 is connected between the two rotating rings 14.

[0047] The first helical blade 10 is disposed inside the mixing drum 4, and the second helical blade 15 is disposed inside the transition discharge shell 3.

[0048] Two feed pipes 5 are connected to the bottom of the mixing drum 4.

[0049] The bottom of the transition discharge shell 3 is connected to the discharge pipe 22, and one end of the discharge pipe 22 is connected to the discharge pipe 23. Valves are provided in the discharge pipe 5, the discharge pipe 22 and the discharge pipe 23. The valves are used to control the opening and closing of the discharge pipe 5, the discharge pipe 22 and the discharge pipe 23. The valves are known technology and are very mature at present. Those skilled in the art can and should understand their specific functions and structures, so they will not be described in detail here.

[0050] The external connection of the discharge pipe 23 has several fixing blocks 24, and one side of the fixing blocks 24 is connected to the top of the fixing frame 1.

[0051] One of the fixed blocks 24 is connected to a grouting pump 25. The output end of the grouting pump 25 is connected to the discharge pipe 23. A flow meter 26 is connected to one side of the discharge pipe 23. When the material is discharged, the material in the transition discharge shell 3 is discharged into the discharge pipe 23 through the discharge pipe 22. At this time, the grouting pump 25 also works to transport the material in the discharge pipe 23 to other equipment. The grouting pump 25 is a piston-type grouting pump. The piston moves back and forth in the cylinder to achieve suction and discharge. When the piston moves outward, the volume of the cylinder cavity increases and the pressure decreases. At this time, the suction valve opens and the discharge valve closes. Under the action of pressure difference, the slurry enters the cavity from the hopper through the suction valve. When the piston moves inward, the volume of the cavity decreases, the slurry is squeezed, and the pressure rises sharply. The suction valve closes and the discharge valve opens. The slurry is pushed to the slurry discharge pipeline through the discharge valve. This cycle continues to transport the slurry. The specific function and structure of the grouting pump 25 are clear to those skilled in the art, so they will not be described in detail here.

[0052] When using this utility model:

[0053] First, the control cabinet 2 is used to control the operation of the stirring device and the operation of the discharge pipe 23. When the stirring device is working, it is divided into two areas: the inside of the stirring drum 4 and the inside of the transition discharge shell 3. The output end of the motor 7 drives the rotating shaft 8 to rotate. At this time, the rotating shaft 8 will drive the mounting ring 9 and the first spiral blade 10 to rotate, and at the same time drive the stirring frame 11 and the scraper 12 to rotate. When the first spiral blade 10 rotates, it works with the stirring frame 11 to stir and mix the material inside the stirring drum 4.

[0054] Secondly, when the material in the mixing drum 4 is stirred and mixed and discharged to the transition discharge shell 3, the material's adhesiveness causes it to adhere to the inner wall of the mixing drum 4, resulting in incomplete material discharge and material waste. Therefore, during discharge, the rotating shaft 8 continues to rotate, which will drive the stirring frame 11 and scraper 12 to rotate. At this time, the bottom of the stirring frame 11 contacts the inner bottom surface of the mixing drum 4, which can assist the material to be discharged into the discharge pipe 5. Moreover, when the scraper 12 rotates, it can scrape the inner wall of the mixing drum 4, causing the material on the inner wall of the mixing drum 4 to fall to the inner bottom surface of the mixing drum 4, which, together with the stirring frame 11, discharges the material.

[0055] Then, of course, the rotating shaft 8 passes through the inner bottom surface of the mixing drum 4 when it rotates, so that the rotating shaft 8 will also drive the connecting shaft 13 to rotate. The connecting shaft 13 will drive the rotating ring 14 and the second spiral blade 15 to rotate, and at the same time drive the connecting rod 16 and the straight scraper 17 to rotate. Specifically, when rotating, the straight scraper 17 will also drive the stirring rod 18, the guide inclined plate 19 and the turbulence inclined rod 21 to rotate. Therefore, when the well-mixed material falls into the transition discharge shell 3 for temporary storage and discharge, it is also necessary to keep stirring. The second spiral blade 15 works in conjunction with the stirring rod 18 to stir the material in the transition discharge shell 3.

[0056] Next, when the material is discharged from the transition discharge shell 3, the straight scraper 17, in conjunction with the guide inclined plate 19, can scrape off the material adhering to the inner wall of the transition discharge shell 3. It should be noted that when the material on the inner wall is scraped off, it will be guided by the guide inclined plate 19 to the inner bottom surface of the transition discharge shell 3. At this time, the scraper 20 and the guide inclined plate 19 cooperate, and the included angle between them will drive the scraped material to move. Since the discharge pipe 22 is set on the rotation path of the included angle, the scraper 20 and the guide inclined plate 19 can discharge the scraped material into the discharge pipe 22, thereby improving the working efficiency of the stirring device.

[0057] Finally, when the material is discharged, the material in the transition discharge shell 3 is discharged into the discharge pipe 23 through the discharge pipe 22. At this time, the grouting pump 25 also works to transport the material in the discharge pipe 23 to other equipment.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
