Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to a device for configuring concrete with a large amount of solid waste. Background Art

[0002] Concrete is a composite material formed by bonding fine aggregate and coarse aggregate with cement and hardening over a period of time. Currently, high-durability concrete with a large amount of recycled coarse aggregate is generally prepared by recycling construction solid waste. During the preparation process, the amount of recycled coarse aggregate and the type of cementitious material are optimized to enhance the chloride ion penetration resistance and frost resistance of the concrete with a large amount of recycled coarse aggregate, so that the concrete has stronger performance.

[0003] The Chinese utility model announcement number CN216465334U discloses a multi-stage mixing system for high-durability, high-volume recycled coarse aggregate concrete. The system uses a first baffle, a second baffle, a first butterfly valve, a second butterfly valve, and a third butterfly valve to allow concrete to be mixed in multiple stages in a mixing barrel. The multi-stage positions of the mixing barrel can mix different batches of concrete, allowing the mixing barrel to mix three batches of concrete simultaneously, ensuring that the mixing system can work continuously and reducing the time spent in mixing each batch of concrete.

[0004] There are at least the following problems in this technology. Although the multi-stage mixing system for high-durability and high-volume recycled coarse aggregate concrete can achieve a multi-stage mixing effect on the materials during the configuration and mixing of the high-durability and high-volume recycled coarse aggregate concrete, the building materials may agglomerate or be mixed with foreign matter during the mixing process of the concrete. These problems have a negative impact on the production of concrete and may affect the quality of the concrete. Therefore, a device for configuring high-volume solid waste concrete is now proposed. Utility Model Content

[0006] The utility model provides a device for preparing concrete with a large amount of solid waste, which adopts the following technical solution: a device for preparing concrete with a large amount of solid waste, comprising a mixing tank, a discharge mounting pipe fixedly mounted on the bottom end of the mixing tank, and a discharge assembly arranged on one side of the discharge mounting pipe, a driving motor being fixedly mounted on the top of the mixing tank, a transmission shaft being fixedly mounted on the output end of the driving motor, a first gear being fixedly mounted on the end of the transmission shaft away from the driving motor, two second gears being meshedly connected on the outer side of the first gear, and a first transmission rod being fixedly mounted below the first gear and the second gear, a first crushing tooth being arranged on the outer side of the first transmission rod, a second transmission rod being fixedly connected below the first transmission rod, and a second crushing tooth being arranged on the outer side of the second transmission rod.

[0007] By adopting the above technical solution, the transmission rod is driven by the driving motor, and the first gear and the second gear are driven to rotate by the transmission rod, so that the first transmission rod and the second transmission rod below are driven by the rotation of the first gear and the second gear to use the first crushing teeth and the second crushing teeth on the outside to crush the construction waste. This can avoid the formation of agglomerates of construction materials and concrete, and when there are agglomerated impurities in the construction materials, the first crushing teeth and the second crushing teeth on the outside of the multiple first transmission rods and the second transmission rods can also crush these agglomerated impurities, so that they are better mixed with the concrete, thereby increasing the production quality of the concrete.

[0008] Optionally, the diameter of the first transmission rod is larger than the diameter of the second transmission rod, and a protection box is provided on the outside of the first gear and the second gear, and the protection box is fixedly mounted on the top surface inside the mixing tank.

[0009] By adopting the above technical solution, the two first transmission rods and the second transmission rods with different diameters can achieve two stirring and crushing effects, and the protection box can protect the first gear and the second gear.

[0010] Optionally, the mixing tank is provided with a filter screen plate at the connection between the first transmission rod and the second transmission rod, and the end of the first transmission rod and the top of the second transmission rod are both rotatably mounted on the filter screen plate.

[0011] By adopting the above technical solution, the filter screen can achieve the bearing and fixing effect on the first transmission rod and the second transmission rod.

[0012] Optionally, a connecting rod is fixedly installed below one group of the second transmission rods, and multiple groups of stirring blocks are fixedly installed on the outer side of the connecting rod.

[0013] By adopting the above technical solution, the connecting rod and the stirring block outside the connecting rod can achieve a stirring effect when discharging material from the discharging installation pipe.

[0014] Optionally, the end of the connecting rod extends to the discharge mounting pipe, and the stirring block is arranged inside the discharge mounting pipe.

[0015] By adopting the above technical solution, the stirring block located at the discharge installation pipe can speed up the discharge of the solid waste concrete after mixing, thereby preventing the solid waste concrete from accumulating at the discharge assembly.

[0016] Optionally, the discharge assembly includes a first mounting seat, which is fixedly mounted on the discharge mounting pipe via a flange, and a second mounting seat is threadedly mounted on the front end of the first mounting seat.

[0017] By adopting the above technical solution, the first mounting seat and the second mounting seat are connected by threads, so that the second mounting seat can be replaced.

[0018] Optionally, the first mounting seat forms a fixed structure with the second mounting seat through a flange.

[0019] By adopting the above technical solution, a fixed connection between the first mounting seat and the second mounting seat is achieved through the flange, which is also convenient for subsequent replacement.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. The utility model drives the transmission shaft through a driving motor, and drives the first gear and the second gear to rotate through the transmission shaft, so that the first gear and the second gear drive the first transmission rod and the second transmission rod below to use the first crushing teeth and the second crushing teeth on the outside to crush the construction waste. This can avoid the formation of agglomerates of construction materials and concrete. When agglomerated impurities exist in the construction materials, the first crushing teeth and the second crushing teeth on the outside of the multiple first transmission rods and the second transmission rods can also crush these agglomerated impurities, so that they are better mixed with the concrete, thereby improving the production quality of the concrete.

The outer side of the first gear 6 is meshed with two second gears 7, and a first transmission rod 8 is fixedly mounted below the first gear 6 and the second gear 7. A first crushing tooth 9 is arranged on the outer side of the first transmission rod 8, and a second transmission rod 10 is fixedly connected to the lower side of the first transmission rod 8, and a second crushing tooth 11 is arranged on the outer side of the second transmission rod 10. The transmission shaft 5 is driven by the driving motor 4, and the rotation of the first gear 6 and the second gear 7 is driven by the transmission shaft 5, so as to realize the rotation of the first gear 6 and the second gear 7 and the second gear below. A transmission rod 8 and a second transmission rod 10 use the first crushing teeth 9 and the second crushing teeth 11 on the outer side to crush the construction waste, which can avoid the formation of agglomerates of construction materials and concrete. When there are agglomerated impurities in the construction materials, the first crushing teeth 9 and the second crushing teeth 11 on the outer sides of the multiple first transmission rods 8 and the second transmission rods 10 can also crush these agglomerated impurities, so that they are better mixed with the concrete, thereby increasing the production quality of the concrete. The diameter of the first transmission rod 8 is larger than the diameter of the second transmission rod 10, and a protection box 12 is provided on the outer side of the first gear 6 and the second gear 7. The protection box 12 is fixedly installed on the top surface inside the mixing tank 1. The mixing tank 1 is provided with a filter plate 13 at the connection between the first transmission rod 8 and the second transmission rod 10. The end of the first transmission rod 8 and the top of the second transmission rod 10 are both rotatably mounted on the filter plate 13. The filter plate 13 can achieve a load-bearing and fixing effect on the first transmission rod 8 and the second transmission rod 10.

The stirring block 15 located at the discharge mounting pipe 2 can speed up the discharge of solid waste concrete after mixing, which can also prevent solid waste concrete from accumulating at the discharge assembly 3. The discharge assembly 3 includes a first mounting seat 301, which is fixedly mounted on the discharge mounting pipe 2 through a flange, and the front end of the first mounting seat 301 is threadedly mounted with a second mounting seat 302.

[0033] The implementation principle of the present invention is as follows: when in use, building materials or other materials are poured into the interior of the mixing tank 1 through the filling pipe, and then the driving motor 4 is turned on, and the transmission shaft 5 is driven by the driving motor 4, and the first gear 6 and the second gear 7 are driven to rotate by the transmission shaft 5, so that the first transmission rod 8 and the second transmission rod 10 below are driven by the rotation of the first gear 6 and the second gear 7 to use the first crushing teeth 9 and the second crushing teeth 11 on the outside to crush the construction waste, so that the generation of building materials and concrete lumps can be avoided, and when there are agglomerated impurities in the building materials, the first crushing teeth 9 and the second crushing teeth 11 on the outside of the multiple first transmission rods 8 and the second transmission rods 10 can also crush these agglomerated impurities, so that they are better mixed with the concrete, thereby increasing the production quality of the concrete, and because the diameters of the first transmission rod 8 and the second transmission rod 10 are different, the effects produced when they are stirred and crushed are also different, so The double mixing configuration effect of mixing materials and concrete can be achieved. After the materials are mixed by the second transmission rod 10 and the second crushing teeth 11, one group of the second transmission rods 10 can drive the connecting rod 14 and the stirring block 15 outside the connecting rod 14 to stir the materials located at the discharge mounting pipe 2, and the discharge speed at the discharge mounting pipe 2 is achieved by stirring the connecting rod 14 and the stirring block 15 outside the connecting rod 14, and the thrust of the configured concrete is exerted by the connecting rod 14 and the stirring block 15 outside the connecting rod 14, thereby reducing the accumulation of concrete at the discharge mounting pipe 2 and the discharge assembly 3 after the configuration is completed. Finally, the configured concrete is discharged through the first mounting seat 301 and the second mounting seat 302. When the first mounting seat 301 and the second mounting seat 302 are in use, they can be selectively replaced according to the subsequent wear degree of the first mounting seat 301 and the second mounting seat 302, which is also convenient for the long-term use of the mixing tank 1.
