Description

Technical Field

[0001] The present invention belongs to the technical field of construction waste regeneration, and in particular, relates to a construction waste regeneration treatment device and method. Background Art

[0002] In the field of demolition of concrete buildings such as buildings, after removing recyclable parts such as glass and steel bars, a large amount of construction waste (concrete, gravel, etc.) will be generated. This part of construction waste is extremely difficult to recycle, and the cost of recycling is high. Generally, this part of construction waste is directly discarded. In order to avoid construction waste from polluting the environment, the means usually taken are to transport construction waste to landfills and bury them deep underground to avoid construction waste being exposed on the surface and generating a large amount of dust. However, in the infiltration of precipitation and / or the flow of groundwater, construction waste comes into contact with water bodies, thereby polluting water bodies. Then, in order to deal with construction waste in a long-term manner, landfilling construction waste becomes a relatively useless means. The existing method is to crush construction waste, use it as aggregate for paving or re-use it as aggregate for concrete, etc. in the construction field. However, when construction waste is used as aggregate, its own strength is insufficient, and its bonding performance with other mixtures such as cement is greatly reduced, which in turn affects the structural strength and stability of roads or buildings. In harsh environments (large temperature differences), cracks are easily generated. At present, using construction waste as raw material for permeable bricks is the preferred solution. However, in the entire permeable brick production process, the production process is relatively cumbersome and cannot achieve the purpose of continuous production. Generally, each process is independent of each other, such as the mixing of aggregates, the addition of materials in the mold and the molding of permeable bricks, which are all completed independently, thereby greatly reducing the production efficiency. Therefore, there is an urgent need for a means of regenerating permeable bricks from construction waste, so that the processing flow of permeable bricks is smoother, the production efficiency of permeable bricks is improved, and the waste of resources caused by abandonment of construction waste is effectively avoided.

The double-material feeding mechanism 100 is arranged above the horizontal workbench 200, the multi-layer material distribution mold 300 is slidably installed on the horizontal workbench 200, the horizontal and vertical driving mechanism 400 and the die forming mechanism 500 are respectively arranged on both sides of the double-material feeding mechanism 100, the horizontal and vertical driving mechanism 400 is connected with the multi-layer material distribution mold 300, and one side of the horizontal workbench 200 passes through the die forming mechanism 500. The working principle and advantages of the present invention are as follows: the present invention has two mixing chambers through the dual-material feeding mechanism 100, the basic crushed material and the base surface crushed material are respectively supplied to the two mixing chambers, the dual-material feeding mechanism 100 is controlled to disturb and convey the materials in the two mixing chambers, and the additives (binders) are respectively injected into the two mixing chambers, and after the basic crushed material and the base surface crushed material are respectively mixed with the additives, humidifying water is respectively added into the two mixing chambers to humidify the basic crushed material and the base surface crushed material. Compared with the existing method of adding additives and humidifying the two materials separately, its efficiency is greatly improved. Afterwards, the basic crushed material and the base surface crushed material are sequentially added into the multi-layer uniform material mold 300. When the basic crushed material is added, the horizontal and vertical driving mechanism 400 is controlled to operate so that the basic crushed material is evenly laid in the multi-layer uniform material mold 300; when the base surface crushed material is added, the horizontal and vertical driving mechanism 400 is controlled to operate so that the base surface crushed material is evenly laid on the upper part of the multi-layer uniform material mold 300. Finally, the compression molding mechanism 500 is used to compression mold it into a permeable brick. When the production is stopped, the injection channel of the additive needs to be cleaned with detergent, clean water, etc. to prevent the additive from staying in the injection channel and condensing and clogging. In the processing of existing permeable bricks, whether the materials are the separate processing of the two materials in the early stage, or the subsequent layered addition, quantitative, and leveling of the materials, all require corresponding equipment to complete, making the entire production process too complicated, greatly delaying the efficiency of production, and the more equipment, the greater the investment cost, and the later maintenance cost will also increase accordingly. In summary, the present invention can effectively improve the fluency of the permeable brick processing process, improve the production efficiency of the permeable bricks, and avoid the waste of resources caused by abandonment of construction waste.

[0038] As a preferred embodiment of the present invention, Figure 1 , 2As shown, the dual material feeding mechanism 100 includes an additive pipe system, a humidifying pipe system and two crushed material feeding units. The two crushed material feeding units are arranged side by side, and the two mixing chambers are formed in the two crushed material feeding units respectively. One end of the two crushed material feeding units is connected to the additive pipe system, and the other end of the two crushed material feeding units is connected to the humidifying pipe system. The base crushed material and the base surface crushed material are disturbed and transported in the two crushed material feeding units respectively, and the additive is supplied to the two crushed material feeding units through the additive pipe system, so that the additive is fully mixed with the base crushed material and the base surface crushed material respectively, and the humidifying water is supplied to the two crushed material feeding units through the humidifying pipe system, so that the humidifying water is fully mixed with the base crushed material and the base surface crushed material respectively.

[0039] As a preferred embodiment of the present invention, Figure 2-4As shown, the crushed material feeding unit includes a horizontal mixing kettle 101, a spiral disturbing blade 108, a first assembly pipe 111 and a second assembly pipe 114. The axis of the horizontal mixing kettle 101 extends in the horizontal direction, and the radial length of the horizontal mixing kettle 101 increases along the conveying direction of the material. The inlet and outlet ends of the horizontal mixing kettle 101 (the small diameter end and the large diameter end of the feed barrel 102) are respectively configured with a feed barrel 102 and a discharge barrel 103. The axes of the horizontal mixing kettle 101, the feed barrel 102 and the discharge barrel 103 coincide. The upper end of the feed barrel 102 is connected with a feed pipe 104, and the lower end of the discharge barrel 103 is connected with a discharge pipe 105. The lower end of the discharge pipe 105 is configured with a discharge nozzle 106 with a gradually expanding diameter, and a discharge control valve 107 is installed on the discharge pipe 105. The spiral disturbing blade 108 of this embodiment is arranged in the horizontal mixing kettle 101, and the spiral disturbing blade 108 extends spirally along the axis of the horizontal mixing kettle 101. The axis of the horizontal mixing kettle 101 coincides with the axis of the spiral disturbing blade 108. The outer wall of the spiral disturbing blade 108 contacts the inner circumferential wall of the horizontal mixing kettle 101, that is, the radial length of the spiral disturbing blade 108 increases along the conveying direction of the material, and when the spiral disturbing blade 108 is driven to rotate, the spiral disturbing blade 108 scrapes the inner circumferential wall of the horizontal mixing kettle 101 to achieve stirring and conveying of the material and avoid the material sticking to the inner circumferential wall of the horizontal mixing kettle 101. The first assembly tube 111 and the second assembly tube 114 of the present embodiment are respectively fixed at the two ends of the spiral disturbing blade 108, and the first assembly tube 111 and the second assembly tube 114 are respectively rotatably connected to the ends of the feed barrel 102 and the discharge barrel 103 that are away from each other, and the axes of the first assembly tube 111, the second assembly tube 114 and the horizontal mixing kettle 101 coincide, and the first assembly tube 111 and the second assembly tube 114 are respectively rotatably connected to the additive piping system and the humidification piping system, and a transmission wheel 113 is coaxially mounted on the first assembly tube 111. The working principle and advantages of this embodiment are: this embodiment drives the transmission wheel 113 to rotate, so that it drives the first assembly pipe 111, the second assembly pipe 114 and the spiral disturbing blade 108 to rotate synchronously, and the basic crushed material or the base surface crushed material enters the horizontal mixing kettle 101 through the feeding pipe 104 and the feeding barrel 102. Under the stirring and conveying of the spiral disturbing blade 108, the basic crushed material or the base surface crushed material gradually moves toward the discharge barrel 103. At the same time, the additive and the humidifying water are respectively injected into the horizontal mixing kettle 101 through the additive pipe system and the humidifying pipe system, so that the basic crushed material or the base surface crushed material is gradually mixed with the additive and the humidifying water during the stirring and conveying process, so that the structural strength of the subsequent pressed permeable bricks reaches the expected standard. Under normal circumstances, it is necessary to add the additive first, mix it sufficiently, and then perform the humidification operation. If the two processes are reversed, the structural strength of the permeable bricks obtained will be relatively weak.

[0040] As a preferred embodiment of the present invention, Figure 2 , 4 As shown, a first liquid chamber and a second liquid chamber that are independent of each other are constructed in the spiral disturbing blade 108. The first liquid chamber is formed by one end of the spiral disturbing blade 108 connected to the first assembly tube 111, and extends to the middle of the spiral disturbing blade 108 along the spiral shape of the spiral disturbing blade 108. The second liquid chamber is formed by one end of the spiral disturbing blade 108 connected to the second assembly tube 114, and extends to the middle of the spiral disturbing blade 108 along the spiral shape of the spiral disturbing blade 108.

The two transverse guide bars 202 are respectively slidably assembled with the two transverse guide grooves 304, thereby achieving the purpose of transverse sliding connection between the basic mold body 301 and the horizontal workbench 200. First limiting edges 303 are respectively constructed on both sides of the upper end of the basic mold body 301, and the secondary mold body 306 is assembled between the two first limiting edges 303, so as to achieve the purpose of longitudinal sliding connection between the secondary mold body 306 and the basic mold body 301.

Moreover, the secondary mold body 306 and the top material equalizing frame 310 are connected to the transverse and longitudinal driving mechanism 400, so that the transverse and longitudinal driving mechanism 400 can drive the secondary mold body 306 and the top material equalizing frame 310 to move transversely or longitudinally. In this embodiment, a plurality of basic cavities 302 are provided on the basic mold body 301, and these basic cavities 302 are arranged at intervals along the longitudinal direction of the basic mold body 301, and a plurality of secondary cavities 307 are provided on the secondary mold body 306, and these secondary cavities 307 are arranged at intervals along the longitudinal direction of the secondary mold body 306.

At this time, the third electromagnet 305 is energized to make it firmly attract the magnetic block 309, thereby achieving the fixed position of the basic mold body 301 and the secondary mold body 306.The top material distribution frame 310 is driven by the transverse and longitudinal drive mechanism 400 to reciprocate along the longitudinal direction of the secondary mold body 306, so that each secondary cavity 307 is filled and scraped flat, and the excess base surface scraps are discharged from the longitudinal ends of the secondary mold body 306; then, the transverse and longitudinal drive mechanism 400 is controlled to drive the multi-layer material distribution mold 300 to move laterally to the die pressing station to facilitate the die pressing operation of the die forming mechanism 500. It can be seen that this embodiment can accurately layer the base scraps and the base surface scraps, and add them into the multi-layer material distribution mold 300 according to a predetermined ratio, thereby improving the consistency of the obtained permeable brick structure and the yield of the permeable brick.
