Description

Technical Field

[0001] The utility model relates to the field of resource recycling devices, in particular to a concrete crushing material reinforcement device and a recycling system. Background Art

[0002] In recent years, the amount of construction waste generated during construction projects has continued to increase, and the construction of new buildings, roads, bridges and other infrastructure has increased rapidly. While the demand for road fillers has increased, the emission of construction waste will continue to grow at a high level.

[0003] On the other hand, traditional gravel replacement solutions such as tailings and coal gangue are highly regional, limited by local industrial layout, and generally require long transportation distances. If we can combine the local construction waste disposal needs and replace part of the base gravel through improved recycling, we will achieve good economic benefits.

[0004] At present, the treatment of concrete waste is to crush it and then add cement, mineral powder and other admixtures to achieve recycling. The surface of the crushed concrete is usually covered with mortar. Due to the low strength and large gaps of the mortar itself, the strength of the recycled concrete does not meet the use requirements. In order to solve this defect, the existing scheme usually uses a cone crusher to strip the mortar from the crushed concrete, but this process has the defects of high energy consumption, low yield rate, and large dust during the treatment process.

[0005] Based on this, this case is brought forward. Utility Model Content

[0006] One of the purposes of the utility model is to provide a concrete crushing material reinforcement device to solve the above-mentioned defects by improving the strength of the mortar wrapping layer.

[0013] Furthermore, the reinforcing liquid storage tank stores one or more of cement slurry, water glass, and epoxy resin.

[0014] The second purpose of the utility model is to provide a concrete crushing material recycling system, comprising:

[0015] Crusher, used to crush concrete waste;

[0016] A dryer, used for drying crushed concrete, wherein the inlet of the dryer is connected to the outlet of the crusher through a conveyor belt;

[0019] A metering device is used to measure the proportion of admixture and reinforced concrete crushed material, the inlet of the metering device is connected to the outlet of the admixture storage tank and the box discharge port of the concrete crushed material reinforcement device through a conveyor belt;

[0020] The stirring device is used for stirring and mixing admixtures and reinforced concrete crushed materials to form an applicable mixture. The outlet of the metering device is connected to the inlet of the stirring device through a conveyor belt.

[0021] Furthermore, it comprises a strength detection device for detecting the strength of the mixed material output from the stirring device.

[0027] The present invention is further described in detail below in conjunction with the embodiments. It should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" herein are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0028] This embodiment provides a concrete crushing material recycling system. Figure 2 As shown, it includes a crusher, a dryer, a concrete crushed material reinforcement device, a mixed material storage tank, a metering device, a stirring device and a strength testing device.

[0029] like Figure 1 As the core component of this embodiment, the concrete crushing material reinforcement device includes a box body 1, a stirring shaft 2, a vacuum pump 3, an infusion pump 4 and a reinforcement liquid storage tank. Among them, the top surface of the box body 1 is provided with a feed port, a feed valve 5 for opening and closing the feed port, a discharge port and a discharge valve 6 for opening and closing the discharge port. The stirring shaft 2 is installed in the box body 1. The air intake of the vacuum pump 3 is connected to the inside of the box body 1 through a pipeline, the inlet of the infusion pump 4 is connected to the outlet of the reinforcement liquid storage tank through a pipeline, and the outlet of the infusion pump 4 is connected to the inside of the box body 1 through a pipeline. The reinforcement liquid needs to have a certain fluidity and can solidify in the air for a certain period of time. In this embodiment, the reinforcement liquid storage tank stores one or more of cement slurry, water glass, and epoxy resin. Preferably, a liquid spray pipe arranged along the length direction of the box body can be set inside 1 of the box body, the inlet of the liquid spray pipe is connected to the outlet of the infusion pump 4, and a plurality of nozzles are arranged at the bottom of the liquid spray pipe along its length direction, so that the reinforcing liquid can be more fully mixed into the crushed stone.

[0030] The concrete waste collected from the site is crushed in a crusher, and the resulting concrete crushed materials are transported to the dryer via a conveyor belt. The dryer is used to dry the concrete crushed materials. This step is crucial. When the moisture content of the concrete crushed materials is high, the gaps in the mortar wrapping layer on the surface of the crushed materials will be filled with water, which will cause the reinforcing liquid to be unable to be pushed into the mortar gaps by atmospheric pressure, affecting the strength of the reinforced concrete crushed materials.

[0031] The concrete crushed materials after drying are poured into the box 1 of the concrete crushed materials reinforcement device through the conveyor belt. The feed port and the discharge port of the box 1 are closed, and the vacuum pump 3 is started to form a vacuum environment in the box 1. At the same time, the infusion pump 4 is started to spray the reinforcing liquid in the reinforcing liquid storage tank into the box 1. At this time, the stirring shaft 2 is also running to mix the reinforcing liquid with the concrete crushed materials. During the mixing process, the reinforcing liquid is wrapped on the surface of the concrete crushed materials (under the vacuum environment, although part of the air in the mortar gap is extracted, there is still some residual, so that the reinforcing liquid at this time cannot completely enter the gap). When the discharge port of the box 1 is opened and the concrete crushed materials are output to the outside of the box 1, the external atmospheric pressure pushes the reinforcing liquid into the mortar gap on the surface of the concrete crushed materials, so that the mortar strength on the surface of the concrete crushed materials is improved to meet the strength requirements for recycled use.

[0032] The inlet of the metering device (two metering devices can be set here to measure the admixture and the concrete crushed material respectively) is connected to the outlet of the admixture storage tank and the box outlet of the concrete crushed material reinforcement device through a conveyor belt. The metering device is used to measure the proportion of the admixture and the reinforced concrete crushed material. The admixture can be a curing agent such as cement and mineral powder, so that the recycled mixture has the best proportion. The outlet of the metering device is connected to the inlet of the stirring device through a conveyor belt. The stirring device stirs and mixes the admixture and the reinforced concrete crushed material to form an applicable mixture.

[0033] Preferably, the system of this embodiment is further provided with a strength detection device for detecting the strength of the mixture output from the stirring device.

[0034] The mixture produced by this system can be used as filler for the pavement base of highway projects, and can also be used where required in other types of projects.

[0035] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection of the rights of the present invention. Any non-substantial changes to the present invention using this concept shall fall within the protection scope of the present invention.
