Description

Technical Field

[0001] The utility model relates to the technical field of concrete accelerating setting agent discharging, in particular to a concrete accelerating setting agent discharging device. Background Art

[0002] Concrete accelerator is a gray powdery product made from a variety of modified components. It mainly contains alumina clinker, soda ash, thickener and other ingredients. This product has the effect of rapid setting and hardening of cement and enhanced water reduction, which can significantly improve the early strength of concrete and maintain other properties of cement. It is an ideal material in concrete and mortar engineering. The concrete accelerator feeding device is an important equipment in the concrete processing and production process. It is mainly used to evenly and efficiently deliver the concrete accelerator into the concrete mixing equipment.

[0003] The design of some accelerator feeding devices fails to fully consider the fluidity of the material, which leads to easy blockage during the feeding process. This may be caused by uneven material particles or unreasonable design of the feeding port. The blockage of feeding will seriously affect the production efficiency and increase the workload of cleaning and maintenance. At the same time, due to the poor feeding, the accelerator may also accumulate inside the equipment, further aggravating the dust pollution problem. Therefore, a concrete accelerator feeding device is proposed to address the above problems. Utility Model Content

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0018] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0019] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

[0022] See also Figure 1-2 , the utility model provides a technical solution:

[0023] A concrete quick-setting agent discharging device includes a discharging hopper 1, a mounting ring 2 and a bracket 3. The top of the mounting ring 2 is fixedly connected to a symmetrically arranged mounting frame 4, the top of the mounting frame 4 is fixedly connected to a motor buffer seat 5, the top of the motor buffer seat 5 is installed with a motor 6, the end of the output shaft of the motor 6 is fixedly connected to a connecting shaft 7, the outer side of the connecting shaft 7 is fixedly connected to evenly arranged scattering rollers 10, and the outer side of the connecting shaft 7 is fixedly connected to a filter screen 11.

[0024] The filter screen 11 is arranged between two groups of scattering rollers 10 of equal length, and the filter screen 11 is arranged on the inner side of the lower hopper 1. This arrangement allows the concrete accelerator to pass through the scattering rollers 10 and filter the concrete accelerator particles that meet the standards through the filter screen 11; the outer side of the connecting shaft 7 is fixedly connected with spring telescopic rods 8 that are evenly arranged and of different lengths, and the end of the spring telescopic rod 8 away from the connecting shaft 7 is fixedly connected with a scraper 9, and the scraper 9 fits the inner wall of the lower hopper 1. This arrangement allows the connecting shaft 7 to drive the spring telescopic rod 8 to rotate when it rotates, and the spring telescopic rod 8 drives the scraper 9 to rotate, and the scraper 9 can scrape off the particles attached to the Concrete accelerator particles on the inner wall of the lower hopper 1; the bottom of the lower hopper 1 is fixedly connected with a symmetrically arranged elastic gasket 12, and the side of the elastic gasket 12 away from the lower hopper 1 is fixedly connected with a baffle 13. This arrangement enables the baffle 13 installed through the elastic gasket 12 to effectively block the concrete accelerator and reduce the occurrence of the concrete accelerator flying out from the bottom of the lower hopper 1; the mounting ring 2 is fixed to the top of the lower hopper 1, and the bracket 3 is symmetrically arranged on both sides of the lower hopper 1 and fixedly connected to the lower end face of the mounting ring 2. This arrangement enables the lower hopper 1 to be installed through the mounting ring 2 and the bracket 3.

[0025] Working process: All electrical appliances in the present invention are provided with an external power supply or a built-in battery. The concrete accelerator is put into the lower hopper 1 from the mounting ring 2. The mounting ring 2 is supported by the bracket 3. Then the motor 6 on the motor buffer seat 5 is started. The motor buffer seat 5 is installed on the top of the lower hopper 1 through the mounting bracket 4. The output shaft of the motor 6 drives the connecting shaft 7 to rotate. The connecting shaft 7 drives the scattering roller 10 and the filter screen 11 to rotate. The scattering roller 10 scatters the concrete accelerator to make the particle size of the concrete accelerator as uniform as possible. Then the concrete accelerator will first be filtered through the filter screen 11 relative to the top, and then after being stirred and scattered by the scattering roller 10 times, it will fall on the filter screen 11 relative to the bottom inside the lower hopper 1. The concrete accelerator particles obtained after filtering through the filter screen 11 at the bottom are basically uniform in size. When the connecting shaft 7 rotates, it drives the spring telescopic rod 8 to rotate, and the spring telescopic rod 8 drives the scraper 9 to rotate. The scraper 9 can scrape off the concrete accelerator particles attached to the inner wall of the lower hopper 1. At the same time, because the output shaft of the motor 6 drives the connecting shaft 7 to rotate at a high speed, the concrete accelerator will not adhere to the breaking roller 10 and the filter screen 11, so that the concrete accelerator can be fully and stably discharged from the bottom of the lower hopper 1 and then proceed to the next step of processing. The baffle 13 installed by the elastic gasket 12 can effectively block the concrete accelerator and reduce the occurrence of the concrete accelerator flying out from the bottom of the lower hopper 1.

[0026] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
