[0002] &Nbsp; Construction waste is the slag, abandoned soil, abandoned materials, residual mud and other wastes generated during the construction, laying or demolition, repair and renovation of various buildings, structures, pipelines, etc. by construction units or individuals. With the acceleration of urbanization, the amount of construction waste generated is increasing day by day. How to efficiently treat and utilize these construction waste has become an urgent problem to be solved. The traditional way of treating construction waste is mostly to transport it to the suburbs or villages for open-air stacking or landfill. This method not only consumes a lot of land acquisition fees and garbage removal fees, but also causes serious environmental pollution due to the spillage and dust, ash and sand flying during the transportation and stacking process. Therefore, it is particularly important to develop a device that can convert construction waste into valuable products. Among them, construction waste recycling brick making technology is one of the important ways;

[0003] However, in the process of recycling construction waste into bricks, drying the bricks is a key step. Traditional drying methods often have problems such as uneven drying and low efficiency, resulting in unstable quality of the bricks and even cracking and deformation. These problems not only affect the performance of the bricks, but also increase production costs and waste rates. Therefore, how to solve the above problems needs to be considered.

The two second pulleys are respectively mounted on the output shaft of the drive motor 4 and the rotating shaft 11;

[0030] As an embodiment of the present invention, it also includes a limiting mechanism, which is used to limit the rotating disk 12 and the placement rack 13. The limiting mechanism includes a circular frame 19 fixedly connected to the lower end of the placement rack 13. A rectangular groove 28 is opened at the upper end of the rotating disk 12. An electromagnet 29 is installed at the inner bottom of the rectangular groove 28. A rectangular plug 31 that can slide up and down is provided in the rectangular groove 28. The rectangular plug 31 is elastically connected to the electromagnet 29 by a second spring 30. The rectangular plug 31 has magnetism. When the electromagnet 29 is energized, the adjacent surfaces of the rectangular plug 31 repel each other with the same polarity. Furthermore, the electromagnet 29, the heating wire 17 and the drive motor 4 are opened and closed synchronously. When the electromagnet 29 is energized, the rectangular plug 31 will be inserted into the circular frame 19.

[0031] As an embodiment of the present invention, it also includes a gas circulation drying mechanism, which is used to perform low-pressure drying treatment on the bricks on the placement rack 13 to improve the efficiency and uniformity of drying. The gas circulation drying mechanism includes a cavity 23 opened on the top inner wall of the shell 1, and a plurality of air inlets are opened at the bottom of the cavity 23. A silica gel drying ball is provided in the cavity 23. The upper end of the shell 1 is fixedly connected to the piston cylinder 6, and the right side space of the piston cylinder 6 is connected to the interior of the cavity 23 through the second one-way tube 22. The right side space of the piston cylinder 6 is connected to the inner top space of the columnar cylinder 32 through the first one-way tube 21. A hollow plate 14 is installed on the right inner wall of the shell 1, and a plurality of exhaust holes 15 are opened on the left side wall of the hollow plate 14. A plurality of heating wires 17 are fixedly connected between the front and rear inner walls of the hollow plate 14. The middle space of the columnar cylinder 32 is connected to the interior of the hollow plate 14 through a connecting pipe. The first one-way tube 21 and the second one-way tube One-way valves are installed inside 22. The one-way valve inside the first one-way tube 21 flows in a one-way direction from the cavity 23 to the right side space of the piston cylinder 6. The one-way valve inside the second one-way tube 22 flows in a one-way direction from the piston cylinder 6 to the top space inside the cylindrical cylinder 32. A transmission 7 is installed on the upper end of the shell 1. The transmission 7 is an accelerator that can amplify the rotation speed of the input end. The input end of the transmission 7 is connected to the output shaft of the drive motor 4 through a first transmission member 5. The input shaft of the transmission 7 extends into the cavity 23 and is equipped with a plurality of stirring blades 24. A piston block 27 that can slide left and right is provided in the piston cylinder 6. The output shaft of the transmission 7 is fixedly connected to the crankshaft 25. The crankshaft 25 and the piston block 27 are rotatably connected by a connecting rod 26. Through the rotation of the crankshaft 25, the connecting rod 26 can make the piston block 27 reciprocate left and right, thereby generating a one-way airflow in the cavity 23, the right side space of the piston cylinder 6 and the top space of the cylindrical cylinder 32.

[0032] As an embodiment of the present invention, a piston column 16 that can slide up and down is provided in the cylindrical tube 32. The lower end of the piston column 16 is elastically connected to the inner bottom of the cylindrical tube 32 through a first spring 18. A connecting port 20 is provided at the inner bottom of the cylindrical tube 32. A connecting hole is provided on the rear side of the top space of the cylindrical tube 32. A manual valve is installed at the connecting hole. The connecting pipe is sealed by the piston column 16 in the initial state. In this way, when a circulating airflow is generated, the interior of the shell 1 can be in a low pressure state, thereby reducing the temperature required for evaporation and improving the drying efficiency.

[0033] In the present invention, first, the brick body is placed in the placement rack 13, and the placement rack 13 is pushed into the upper end of the rotating disk 12 inside the housing 1. Then, the sealing door 3 is closed and the drive motor 4 is started. At this time, the electromagnet 29 and the heating wire 17 are started synchronously. The repulsive effect of the electromagnet 29 and the rectangular plug 31 ensures that the placement rack 13 is stably limited during the rotation process.

[0034] After the driving motor 4 rotates, its output shaft drives the input shaft and the rotating shaft 11 of the transmission 7 to rotate respectively through the first transmission member 5 and the second transmission member 10. The output shaft of the transmission 7 drives the piston block 27 to reciprocate left and right in the piston cylinder 6 through the crankshaft 25 and the connecting rod 26, which will generate a one-way gas flow inside the shell 1, the cavity 23, the piston cylinder 6 and the top space of the cylindrical cylinder 32. This one-way gas flow will reduce the air pressure inside the shell 1 and increase the air pressure at the top of the cylindrical cylinder 32. After that, it pushes the piston column 16 downward. When the piston column 16 moves downward to the point where its upper end surface is lower than the connecting pipe, the gas in the columnar tube 32 enters the hollow plate 14 and is finally discharged from the exhaust hole 15 to maintain balance, forming a circulating airflow. The circulating airflow is heated at the electric heating wire 17 to form a circulating heated airflow to achieve brick drying. The water vapor generated by drying is absorbed by the silica gel drying ball in the cavity 23. In addition, the circulating airflow can keep the interior of the shell 1 at a low pressure, the evaporation temperature is lower, and the drying efficiency is improved.

[0035] In addition, the input shaft of the transmission 7 drives the stirring blades 24 to stir in the cavity 23, promoting the movement of the silica gel drying balls, allowing them to come into more comprehensive contact with the circulating gas and achieve better moisture absorption effect;

[0036] At the same time, the rotating shaft 11 drives the rotating disk 12 to rotate, so that the placement rack 13 and the bricks to be dried thereon are evenly heated, thereby improving the drying uniformity. After the drying is completed, the sealing door 3 is opened and the placement rack 13 can be taken out.
