Description

An improved accelerator addition device Technical Field

[0001] This utility model relates to the field of accelerator addition technology, specifically an improved accelerator addition device. Background Technology

[0002] During mine tunnel excavation, to ensure construction quality and service life, after blasting and rockfall, anchor bolts are used for support followed by shotcrete covering. In addition to concrete, a quick-setting agent is added to the shotcrete slurry to accelerate the solidification of the slurry sprayed onto the tunnel walls. This leads to the development of an improved quick-setting agent additive device.

[0003] For example, a quick-setting agent addition device with announcement number "CN209649140U" uses a stirring device and a double-screw conveyor to ensure uniform mixing of quick-setting agent and aggregate. The entire device operates in a closed space, reducing dust generation and meeting environmental protection requirements. However, the device uses levers and paddles to directly rub against hard aggregates, which is prone to wear and deformation (especially when processing materials such as quartz sand and steel fibers). This results in severe mechanical wear and high maintenance costs. In addition, the bearings and levers of the stirring rod bear a large torque, leading to high energy consumption during long-term operation. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of easy wear and deformation when using levers and blades to directly rub against hard aggregates (especially when processing materials such as quartz sand and steel fibers), resulting in severe mechanical wear and high maintenance costs. At the same time, the bearings and levers of the stirring rod bear a large torque, leading to high energy consumption during long-term operation. Therefore, an improved accelerator addition device is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An improved quick-setting agent addition device is designed, comprising a base plate, a vertical plate, and a roller. The upper right side of the outer wall of the base plate is fixedly connected to the vertical plate. The left side of the outer wall of the roller is provided with a quick-setting agent addition and mixing structure. The left end of the roller is provided with a sealing structure. Multiple lining plates are fixedly connected to the inner wall of the roller.

[0007] Preferably, the quick-setting agent addition mixing structure includes a shell, the lower end of the outer wall of the shell is fixedly connected to the base plate, the lower right end of the shell is fixedly connected to a motor via a bracket, the end of the output shaft of the motor is fixedly connected to a first gear, the rotating shaft of the first gear is rotatably connected to the shell via a bearing, the outer wall of the first gear is meshed with a second gear, and the inner wall of the second gear is fixedly connected to a roller.

[0008] Preferably, the outer wall of the roller is rotatably connected to the outer shell via a bearing, and a cover plate is installed in the middle of the front side of the outer shell.

[0009] Preferably, the sealing structure includes a first sleeve, the right end of the inner wall of the first sleeve is rotatably connected to the roller through a sealing bearing, the left side of the inside of the first sleeve is threadedly connected to the sealing cap, a turntable is fixedly connected to the middle of the left side of the sealing cap, the right end of the roller is rotatably connected to the second sleeve through a sealing bearing, and the right side of the outer wall of the second sleeve is fixedly connected to the vertical plate.

[0010] Preferably, the lower end of the second sleeve is fixedly connected to the pipeline, and the upper end of the first sleeve is fixedly connected to the feed hopper.

[0011] Preferably, a top cover is fastened to the upper end of the outer wall of the feed hopper.

[0012] The improved quick-setting agent addition device proposed in this utility model has the following advantages: Through the quick-setting agent addition and mixing structure, the motor starts and drives the first gear to rotate in the outer shell through the bearing. The rotation of the first gear drives the second gear to rotate, which in turn drives the drum to rotate in the outer shell through the bearing. At the same time, both ends of the drum can rotate in the first and second sleeves through sealed bearings. The liner rotates with the roller. The motor ultimately drives the drum and the liner to rotate, which agitates and disperses the flocculant and aggregate entering the drum. There are no high-speed rotating levers or paddles, which effectively reduces wear points, thereby increasing service life and reducing maintenance costs. At the same time, compared with the prior art, the drum only needs to rotate at a low speed (usually 20-30 RPM), and the motor power requirement is much lower than that of the high-speed stirring rod, resulting in lower energy consumption.

[0013] By using the sealing structure, the turntable is rotated outward, which drives the cover to rotate and detach it from the first sleeve, making the left end of the first sleeve open. If necessary, the cover can be removed, which facilitates the cleaning of aggregates and accelerators inside the device by workers, thus improving its practicality. Attached Figure Description

[0024] Referring to Figures 1-3 and 5: The quick-setting agent addition mixing structure 2 includes a shell 204. The lower end of the outer wall of the shell 204 is fixedly connected to the base plate 4. A motor 201 is fixedly connected to the lower right side of the shell 204 via a bracket. The motor 201 is a servo motor. A first gear 202 is fixedly connected to the end of the output shaft of the motor 201. The rotating shaft of the first gear 202 is rotatably connected to the shell 204 via a bearing. The motor 201 can drive the first gear 202 to rotate within the shell 204 via the bearing. The outer wall of the first gear 202 is meshed with a second gear 203. The rotation of the first gear 202 can drive the rotation of the second gear 203. The inner wall of the second gear 203 is fixedly connected to the roller 8.

[0025] Referring to Figures 1-2 and 4-5: The sealing structure 1 includes a first sleeve 103. The right end of the inner wall of the first sleeve 103 is rotatably connected to the roller 8 through a sealing bearing. The left side of the inside of the first sleeve 103 is threadedly connected to the cover 101. A sealing ring is fixed on the outer ring of the right side of the cover 101 to ensure relative sealing with the roller 8.

[0026] A turntable 102 is fixedly connected to the middle of the left side of the cover 101. The cover 101 can be driven to rotate by the turntable 102. The right end of the roller 8 is rotatably connected to the second sleeve 104 through a sealed bearing. Both ends of the roller 8 can rotate in the first sleeve 103 and the second sleeve 104 respectively through sealed bearings. The right side of the outer wall of the second sleeve 104 is fixedly connected to the vertical plate 5.

[0027] Working principle:

[0028] Accelerator addition and mixing process:

[0029] When it is necessary to add and mix the accelerator, firstly, the aggregate is weighed using an external weighing system, and the appropriate proportion of accelerator is prepared. Then, the pipe 7 is connected to the feed port of the external shotcrete machine. Then, the upper cover of the feed hopper 6 is opened, and the external power supply of the motor 201 is connected. The motor 201 starts and drives the first gear 202 to rotate in the outer shell 204 through the bearing. The rotation of the first gear 202 drives the second gear 203 to rotate, and then drives the roller 8 to rotate in the outer shell 204 through the bearing via the second gear 203. At the same time, both ends of the roller 8 can rotate in the first sleeve 103 and the second sleeve 104 through the sealed bearing. The liner 4 rotates with the roller 8.

[0030] Then, the weighed aggregate and the corresponding proportion of quick-setting agent are poured into the feed hopper 6. The aggregate and quick-setting agent flow into the first sleeve 103, and through the lower slope of the cover 101, they flow into the drum 8. The aggregate and quick-setting agent are agitated and stirred by the liner 3 inside the drum 8. The inside of the drum 8 is a cone shape with the left side higher than the right side, which causes the aggregate and quick-setting agent to flow towards the second sleeve 104. The stirred materials (aggregate and quick-setting agent) flow into the second sleeve 104 and through the pipe 7 to the outside shotcrete machine for use. This movement can be used to add and mix flocculants.

[0031] Roller cleaning process:

[0032] When it is necessary to clean the residue inside the drum 8, the material inside the device is emptied in the manner described above. Then, the connection between the pipe 7 and the feed port of the external shotcrete machine is disconnected. Further, the turntable 102 is rotated outward, and the turntable 102 drives the cover 101 to rotate, causing it to disengage from the first sleeve 103, so that the left end of the first sleeve 103 is in an open state. Then, the staff can use an external high-pressure water gun to rinse the residue inside the device. The rinsing wastewater and residual material are discharged through the pipe 7, and the discharged material can be collected by an external material box. After rinsing the inside of the device, the turntable 102 is rotated back to the cover 101 to seal the first sleeve 103. The outer ring of the right side of the cover 101 is fixed with a sealing ring, which can ensure the relative sealing with the first sleeve 103. In addition, the rotation direction of the cover 101 is consistent with the rotation and placement of the drum 8 to prevent the cover 101 from loosening.

[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
