Description

Technical Field

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

[0002] In the field of demolition of concrete buildings such as buildings, after removing recyclable components such as glass and steel bars, a large amount of construction waste (such as concrete and crushed stones) will be generated. This part of the construction waste is extremely difficult to recycle, and the cost of recycling is relatively high. Generally, this part of the construction waste is directly discarded. In order to avoid environmental pollution caused by construction waste, the commonly adopted means is to transport the construction waste to a landfill and bury it deep underground to prevent the construction waste from being exposed on the ground surface and generating a large amount of dust. However, due to the infiltration of precipitation and / or the flow of groundwater, the construction waste comes into contact with water bodies, thus polluting the water bodies. Then, in order to treat construction waste in a long-term manner, landfilling construction waste becomes a rather useless means. The existing method is to crush the construction waste and use it as aggregate for paving roads or for making concrete again and other applications in the construction field. However, when choosing construction waste as aggregate, its own strength is insufficient, and its bonding performance with other mixtures such as cement is greatly reduced, thereby affecting the structural strength and stability of roads or buildings. In a harsh environment (with large temperature differences), cracks are extremely likely to occur. Currently, using construction waste as the raw material for permeable bricks is a preferred solution. However, in the entire production process of permeable bricks, the production process is relatively cumbersome and cannot achieve the purpose of continuous production. Generally, each process is independent, such as the stirring and mixing of aggregates, the addition of materials in the mold, and the forming of permeable bricks, all of which are completed independently, thereby greatly reducing the production efficiency. Therefore, there is an urgent need for a means of recycling construction waste to produce permeable bricks, making the processing process of permeable bricks smoother, improving the production efficiency of permeable bricks, and effectively avoiding the waste of resources caused by the abandonment of construction waste.

Detailed implementation mode

[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0037] The present invention discloses a construction waste recycling treatment device, as Figures 1-12As shown in the figure, it includes a dual-material feeding mechanism 100, a horizontal working table 200, a multi-layer material leveling die 300, a transverse and longitudinal driving mechanism 400, and a die pressing and forming mechanism 500. Among them, the dual-material feeding mechanism 100 is arranged above the horizontal working table 200, the multi-layer material leveling die 300 is slidably installed on the horizontal working table 200, the transverse and longitudinal driving mechanism 400 and the die pressing and forming mechanism 500 are respectively arranged on both sides of the dual-material feeding mechanism 100, the transverse and longitudinal driving mechanism 400 is connected to the multi-layer material leveling die 300, and one side of the horizontal working table 200 passes through the die pressing and forming mechanism 500. The working principle and advantages of the present invention are as follows: The dual-material feeding mechanism 100 of the present invention has two mixing chambers, 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 at the same time, additives (binders) are respectively injected into the two mixing chambers. After the basic crushed material and the base surface crushed material are respectively mixed with the additives, humidifying water is respectively added to the two mixing chambers to humidify the basic crushed material and the base surface crushed material respectively. Compared with the existing method of separately adding additives and humidifying the two materials, the efficiency is greatly improved. Then, the basic crushed material and the base surface crushed material are sequentially added to the multi-layer material leveling die 300. When the basic crushed material is added, the transverse and longitudinal driving mechanism 400 is controlled to act, so that the basic crushed material is evenly laid in the multi-layer material leveling die 300; when the base surface crushed material is added, the transverse and longitudinal driving mechanism 400 is controlled to act, so that the base surface crushed material is evenly laid on the upper part of the multi-layer material leveling die 300. Finally, the die pressing and forming mechanism 500 is used to press and form it into a permeable brick. During shutdown, the injection channels of the additives need to be cleaned with cleaning agents, clean water, etc. to prevent the additives from staying in the injection channels and coagulating and blocking. For the processing of the existing permeable bricks, whether it is the separate treatment of the two materials in the early stage or the subsequent layered addition, quantification, leveling, etc. of the materials, corresponding equipment is required to complete, which makes the entire production process too complicated, greatly delaying the production efficiency, and the more equipment there is, the greater the investment cost, and the subsequent maintenance cost will also increase accordingly. In summary, the present invention can effectively improve the smoothness of the permeable brick processing process, improve the production efficiency of the permeable brick, and avoid the occurrence of resource waste caused by the abandonment of construction waste.

[0038] As a preferred embodiment of the present invention, as Figure 1 、 2As shown, the dual-feed mechanism 100 includes an additive pipeline system, a humidification pipeline system, and two shredded material feed units. Among them, the two shredded material feed units are arranged side by side, and the above-mentioned two mixing chambers are respectively formed within the two shredded material feed units. One end of these two shredded material feed units is connected to the additive pipeline system, and the other end of the two shredded material feed units is connected to the humidification pipeline system. The basic shredded material and the base surface shredded material are respectively disturbed and conveyed within the two shredded material feed units. The additive is supplied into the two shredded material feed units through the additive pipeline system, so that the additive is fully mixed with the basic shredded material and the base surface shredded material respectively. The humidifying water is supplied into the two shredded material feed units through the humidification pipeline system, so that the humidifying water is fully mixed with the basic shredded material and the base surface shredded material respectively.

[0039] As a preferred embodiment of the present invention, as Figures 2-4As shown in the figure, the shredded material feeding unit includes a horizontal mixing kettle 101, a spiral material disturbing blade 108, a first assembly pipe 111, and a second assembly pipe 114. Among them, 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. At the inlet and outlet ends of the horizontal mixing kettle 101 (the small-diameter end and the large-diameter end of the feeding cylinder 102), a feeding cylinder 102 and a discharging cylinder 103 are respectively constructed. The axes of the horizontal mixing kettle 101, the feeding cylinder 102, and the discharging cylinder 103 coincide. A feeding pipe 104 is connected to the upper end of the feeding cylinder 102, and a discharging pipe 105 is connected to the lower end of the discharging cylinder 103. At the lower end of the discharging pipe 105, a discharging nozzle 106 with a gradually expanding diameter is constructed, and a discharging control valve 107 is installed on the discharging pipe 105. The spiral material disturbing blade 108 of this embodiment is arranged inside the horizontal mixing kettle 101. The spiral material disturbing blade 108 extends spirally along the axis of the horizontal mixing kettle 101. The axes of the horizontal mixing kettle 101 and the spiral material disturbing blade 108 coincide. The outer wall of the spiral material disturbing blade 108 contacts the inner peripheral wall of the horizontal mixing kettle 101, that is, the radial length of the spiral material disturbing blade 108 increases along the conveying direction of the material. And during the process of driving the spiral material disturbing blade 108 to rotate, the spiral material disturbing blade 108 scrapes the inner peripheral wall of the horizontal mixing kettle 101, realizing the stirring and conveying of the material, and avoiding the adhesion of the material on the inner peripheral wall of the horizontal mixing kettle 101. The first assembly pipe 111 and the second assembly pipe 114 of this embodiment are respectively fixed at both ends of the spiral material disturbing blade 108. The first assembly pipe 111 and the second assembly pipe 114 are respectively rotatably connected to the ends of the feeding cylinder 102 and the discharging cylinder 103 that are far away from each other. Moreover, the axes of the first assembly pipe 111, the second assembly pipe 114, and the horizontal mixing kettle 101 coincide. The first assembly pipe 111 and the second assembly pipe 114 are respectively rotatably connected to the additive pipe system and the humidifying pipe system. A transmission wheel 113 is coaxially assembled on the first assembly pipe 111. The working principle and advantages of this embodiment are as follows: In this embodiment, by driving the transmission wheel 113 to rotate, it drives the first assembly pipe 111, the second assembly pipe 114, and the spiral material disturbing blade 108 to rotate synchronously. The basic shredded material or the base shredded material enters the horizontal mixing kettle 101 through the feeding pipe 104 and the feeding cylinder 102. Under the stirring and conveying of the spiral material disturbing blade 108, the basic shredded material or the base shredded material gradually moves towards the discharging cylinder 103. At the same time, through the additive pipe system and the humidifying pipe system, the additive and the humidifying water are respectively injected into the horizontal mixing kettle 101, so that the basic shredded material or the base shredded material is gradually and fully mixed with the additive and the humidifying water during the stirring and conveying process, making the structural strength of the subsequent pressed permeable brick reach the expected standard. Under normal circumstances, it is necessary to add the additive first, and after full mixing, then carry out the humidifying operation. If the two processes are reversed, the structural strength of the obtained permeable brick is relatively weak.

[0040] As a preferred embodiment of the present invention, asFigure 2 , 4 As shown, a first liquid cavity and a second liquid cavity are independently formed in the spiral material disturbing blade 108. The first liquid cavity extends from the end of the spiral material disturbing blade 108 connected to the first assembly pipe 111 to the middle of the spiral material disturbing blade 108 along the spiral shape of the spiral material disturbing blade 108. The second liquid cavity extends from the end of the spiral material disturbing blade 108 connected to the second assembly pipe 114 to the middle of the spiral material disturbing blade 108 along the spiral shape of the spiral material disturbing blade 108. The first liquid cavity and the second liquid cavity are respectively communicated with the first assembly pipe 111 and the second assembly pipe 114. A plurality of first liquid outlet holes 109 are distributed on the spiral material disturbing blade 108 at the position of the first liquid cavity, and these first liquid outlet holes 109 are all communicated with the first liquid cavity; a plurality of second liquid outlet holes 110 are distributed on the spiral material disturbing blade 108 at the position of the second liquid cavity, and these second liquid outlet holes 110 are all communicated with the second liquid cavity. The additive pipe system of this embodiment includes a first liquid inlet main pipe 116 and two first liquid inlet branch pipes 117. These two first liquid inlet branch pipes 117 are both communicated with the outlet end of the first liquid inlet main pipe 116. A first adapter sleeve 112 is formed at the end of the first assembly pipe 111. The two first liquid inlet branch pipes 117 are respectively rotatably connected to the two first adapter sleeves 112, and a first control valve 118 is installed on each first liquid inlet branch pipe 117. The humidifying pipe system of this embodiment includes a second liquid inlet main pipe 119 and two second liquid inlet branch pipes 120. These two second liquid inlet branch pipes 120 are both communicated with the outlet end of the second liquid inlet main pipe 119. A second adapter sleeve 115 is formed at the end of the second assembly pipe 114. The two second liquid inlet branch pipes 120 are respectively rotatably connected to the two second adapter sleeves 115, and a second control valve 121 is installed on each second liquid inlet branch pipe 120. The working principle and advantages of this embodiment are as follows: In this embodiment, the additive is pressurized and injected into the first liquid inlet main pipe 116, and the different opening degrees of the two first control valves 118 are controlled, so that the additive enters the two first assembly pipes 111 through the two first liquid inlet branch pipes 117 respectively; when the additive enters the first liquid cavity of the spiral material disturbing blade 108 through the first assembly pipe 111, with the rotation of the spiral material disturbing blade 108, during the process of stirring and conveying the material, the additive can be fully combined with the material, improving the mixing efficiency. After the additive is mixed, the material is conveyed to the area affected by the humidifying water. The humidifying water is pressurized and injected into the second liquid inlet main pipe 119, and the different opening degrees of the two second control valves 121 are controlled, so that the humidifying water enters the two second assembly pipes 114 through the two second liquid inlet branch pipes 120 respectively; when the humidifying water enters the second liquid cavity of the spiral material disturbing blade 108 through the second assembly pipe 114, with the rotation of the spiral material disturbing blade 108, during the process of stirring and conveying the material, the humidifying water can be fully combined with the material, improving the humidifying efficiency of the material.

[0041] As a preferred embodiment of the present invention, as Figures 7-9As shown, the multi-layer material distribution mold 300 includes a basic mold body 301, a secondary mold body 306 and a top material distribution frame 310, and the basic mold body 301, the secondary mold body 306 and the top material distribution frame 310 are arranged in sequence from bottom to top. Among them, transverse guide grooves 304 are respectively constructed at both ends of the longitudinal direction of the basic mold body 301, and two transverse guide bars 202 are constructed side by side on the horizontal workbench 200. 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. Second limiting edges 308 are respectively constructed on both sides of the upper end of the secondary mold body 306, and the top material equalizing frame 310 is assembled between the two second limiting edges 308, so as to realize the purpose of longitudinal sliding connection of the top material equalizing frame 310 to the secondary mold body 306. 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. When the two ends of the basic mold body 301 and the two ends of the secondary mold body 306 are aligned, the basic cavities 302 and the secondary cavities 307 are aligned one by one. In this embodiment, third electromagnets 305 are respectively installed at both ends of the upper end of the basic mold body 301, and magnetic blocks 309 are respectively fixed at both ends of the lower end of the secondary mold body 306. In this embodiment, when the basic crushed material is loaded at the basic crushed material loading station, the basic crushed material is filled in each basic cavity 302, and the secondary mold body 306 is driven to reciprocate along the longitudinal direction of the basic mold body 301 by the horizontal and vertical driving mechanism 400, so that the basic crushed material evenly fills each basic cavity 302, and the excess basic crushed material is discharged from the longitudinal ends of the basic mold body 301; then, the multi-layer material equalization mold 300 is driven by the horizontal and vertical driving mechanism 400 to move to the base surface crushed material loading station, and the base surface crushed material is filled in the secondary cavity 307 above each basic cavity 302. 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 layer material spreading frame 310 is driven by the horizontal and vertical driving mechanism 400 to reciprocate longitudinally along the secondary layer die body 306, so that each secondary layer cavity 307 is filled and leveled, and the excess base surface debris is discharged from the longitudinal ends of the secondary layer die body 306; then, the horizontal and vertical driving mechanism 400 is controlled to drive the multi-layer material spreading die 300 to displace horizontally to the die pressing station, so as to facilitate the die pressing operation of the die pressing forming mechanism 500.
