Description

Technical Field

[0001] The utility model relates to the technical field of concrete additive production equipment, and particularly relates to a quantitative feeding device for concrete additives. Background Technique

[0002] Concrete additives are chemical substances used to improve the performance of concrete. They can be added during the concrete preparation process to change certain properties of the concrete, such as increasing strength, improving fluidity, reducing shrinkage cracks, etc. There are many types of concrete additives, including water reducers, retarders, early strength agents, antifreeze agents, etc. These additives can be selected according to actual needs to meet the requirements of different projects for the performance of concrete.

[0003] The existing authorized publication number is CN213133095U, which provides a feeding mechanism for the production of concrete additives, relating to the technical field of additive production, including a feeding hopper. One side of the inner wall of the feeding hopper is fixedly installed with a plate shell. The top of the plate shell is fixedly installed with a support leg. The top of the support leg is fixedly installed with an electric motor. The front surface of the rotating shaft of the electric motor is fixedly installed with a turntable. The front surface of the turntable is rotatably connected with a push rod. The front surface of the push rod is rotatably connected with a moving rod. The front surface of the push rod is rotatably connected with a moving rod. In the utility model, when adding raw materials, the switch is turned on, the electric motor drives the turntable to rotate, the turntable drives the top of the push rod to rotate, the limiting cylinder limits the movement of the limiting rod, so that the rectangular plate limits the moving rod through the connecting frame, the push rod drives the moving rod to move back and forth, and the moving rod drives the rectangular plate to reciprocate inside the plate shell through the connecting frame, constantly changing the diameter of the feeding port to prevent the raw materials from being blocked in the device.

[0004] Adopting the above technical solution, although the problem of raw materials being blocked in the device can be prevented, precise quantitative control is not achieved during the feeding process of the equipment. This results in inaccurate dosing of the concrete additives during the addition and mixing of the concrete additive raw materials, which not only affects the product quality but may also have a negative impact on the stability and efficiency of the production process. Therefore, we provide a quantitative feeding device for concrete additives. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0025] The present utility model provides a technical solution: As Figures 1 - 5As shown in the figure, in this embodiment, a device for quantitatively feeding a concrete additive includes: a quantitative mechanism 1. The quantitative mechanism 1 includes a mixing tank 11. On one side of the mixing tank 11, there is a feed hopper 12. On one side of the bottom of the feed hopper 12 close to the mixing tank 11, there is a material guiding port 13. The inner wall of the clamping groove opened on one side of the mixing tank 11 is fixedly connected to the outside of the material guiding port 13. One end of the material guiding port 13 close to the feed hopper 12 is fixedly connected to one side of the bottom of the feed hopper 12 close to the mixing tank 11. On one side of the inner wall of the feed hopper 12 close to the mixing tank 11, there is a scale line 14. On one side of the feed hopper 12, there is an installation bin 15. On one side of the inside of the feed hopper 12 close to the installation bin 15, there is a reserved groove 111. In the installation bin 15, there is a telescopic cylinder 16. One end of the telescopic cylinder 16 close to the reserved groove 111 is provided with a push plate 17. The outside of the telescopic cylinder 16 is fixedly connected to the inner wall of the installation bin 15. The output end of the telescopic cylinder 16 on the side close to the push plate 17 is fixedly connected to one side of the push plate 17. On the top of the push plate 17, there is a baffle 18. On both sides of the baffle 18, there are sliding blocks 19. The top of the push plate 17 is fixedly connected to one side of the bottom of the baffle 18. The outer surface of the push plate 17 is slidably connected to the inner wall of the reserved groove 111. On both sides of the baffle 18, there are fixedly connected sliding blocks 19. On both sides of the inner wall of the feed hopper 12, there are opened sliding grooves 110. On the top side of the feed hopper 12 close to the reserved groove 111, there is a slope plate 112. The outside of the sliding block 19 is slidably connected to the inner wall of the sliding groove 110. Both sides of the slope plate 112 are fixedly connected to both sides of the inner wall of the feed hopper 12. In the clamping groove opened on one side of the top of the mixing tank 11, there is docked a feed port 31. The top of the mixing tank 11 is fixedly connected to the bottom surface of a motor 32. The output end at the bottom of the motor 32 is fixedly connected to a stirring paddle 33. On the top of the slope plate 112, there is an auxiliary mechanism 2.

[0026] In this embodiment, when the staff needs to use this device to quantitatively feed the concrete additive, the concrete can be added into the mixing tank 11 through the feed port 31. Then, the staff can adjust the concrete additive into the feed hopper 12. In order to ensure that the dosage standard of the additive does not exceed the standard, it can be added according to the scale line 14. The additive can be blocked by the baffle 18 to prevent the additive from mixing with the concrete material without controlling the dosage. When the dosage of the additive is adjusted, the telescopic cylinder 16 can be started to drive the push plate 17 to move towards the reserved groove 111. Therefore, the baffle 18 will move towards the reserved groove 111 along with the movement of the push plate 17. During the movement of the baffle 18, the sliding block 19 will slide in the sliding groove 110, making the sliding of the baffle 18 smoother. Therefore, as the baffle 18 moves, the additive in the feed hopper 12 will lose the blocking effect and then fall into the material guiding port 13. The additive is guided into the mixing tank 11 through the material guiding port 13. By starting the motor 32 to drive the stirring paddle 33, the concrete additive and the concrete are mixed and stirred to ensure the quality of the processed concrete material.

[0027] As Figures 2 - 4 shown, the auxiliary mechanism 2 includes a sieve 21. A lifting plate 22 is fixedly connected to the top of the sieve 21. Docking grooves 23 are respectively formed on both sides of the inner wall of the feed hopper 12, and both sides of the sieve 21 are respectively slidably connected to the inner walls of the two docking grooves 23.

[0028] In this embodiment, when the state of the concrete additive is solid granular, the solid granular additive can be filtered and fed through the sieve 21, which can effectively prevent the solid granular additive from blocking the feed hopper 12, separate larger particles from smaller particles, and the sieve 21 can be taken out of the feed hopper 12 for cleaning by lifting the lifting plate 22.

[0029] The utility model provides a device for quantitatively feeding a concrete additive, and the specific working principle is as follows:

[0030] When a worker needs to use the device to quantitatively feed the concrete additive, the concrete can be added into the mixing tank 11 through the feed port 31. Subsequently, the worker can adjust the concrete additive into the feed hopper 12 to ensure that the dosage standard of the additive does not exceed the standard. To achieve this goal, the addition can be made according to the scale line 14. During the addition process, the baffle 18 can play a role in blocking the additive to prevent the additive from mixing with the concrete material without controlling the dosage. Once the dosage of the additive is adjusted, the worker can start the telescopic cylinder 16 to drive the push plate 17 to move towards the reserved groove 111. In this way, the baffle 18 will move towards the direction of the reserved groove 111 along with the movement of the push plate 17. During the movement of the baffle 18, the slider 19 will slide in the chute 110. Along with the movement of the baffle 18, the additive in the feed hopper 12 will lose the blocking effect and then fall into the material guiding port 13. Through the material guiding port 13, the additive will be guided into the mixing tank 11. Finally, the worker can start the motor 32 to drive the stirring paddle 33 to mix and stir the concrete additive and the concrete.
