[0002] Clinker production line refers to the collection of equipment used to produce cement, which includes processes such as raw material crushing, burning and grinding. Among them, it is an important step to send the mixture of raw materials into heat treatment equipment such as rotary kilns or vertical kilns to make chemical changes through high temperature treatment. In the kiln, the raw materials are heated to about 1450 degrees Celsius to form clinker. However, the traditional clinker production process has the following defects:

[0003] Traditional clinker firing mainly relies on fossil fuels, such as coal and natural gas, to provide the required high-temperature heat energy, which will lead to increasing energy shortages in the long run, increase carbon emissions, and increase the burden on the environment.

[0004] If the waste heat is not recovered and utilized in time, waste heat will be generated during the heat treatment of clinker. If the waste heat is not recovered and utilized in time, it will cause waste of energy and increase the energy consumption cost of the factory.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] To solve the technical problems of how to load and unload the kiln, please refer to Figure 1-Figure 5 , this embodiment provides the following technical solutions:

[0027] A multi-energy coordinated utilization device for a clinker production line comprises a vertical kiln 1 and a photoelectric conversion mechanism 2. Feeding cylinders 11 are symmetrically installed on the left and right sides of the upper end of the vertical kiln 1. The bottom end of the vertical kiln 1 is sealedly connected to a discharge cylinder 12 through a discharge pipe 13, and a valve body 131 is installed outside the discharge pipe 13.

[0028] A feeding port 111 is provided at the upper end of the feed cylinder 11, and a discharge port 121 is provided at the lower end of the discharge cylinder 12. A rotating shaft 17 is movably installed in both the feed cylinder 11 and the discharge cylinder 12, and a spiral blade 171 is fixedly provided outside the rotating shaft 17. One end of the rotating shaft 17 is connected to a motor 172.

[0029] Specifically, when loading is required, the raw materials are put into the feeding barrel 11 through the feeding port 111. At this time, the motor 172 drives the rotating shaft 17 and the spiral blade 171 to rotate, so that the raw materials are slowly and orderly transported to the vertical kiln 1. When the raw materials are burned into clinker, the valve body 131 is opened, and the clinker falls from the vertical kiln 1 into the discharge barrel 12. At this time, the motor 172 drives the rotating shaft 17 and the spiral blade 171 to rotate, so that the clinker is slowly and orderly transported to the discharge port 121, and then discharged from the discharge port 121.

[0030] In order to solve the technical problem of how to recover waste heat from kilns, please refer to Figure 1-Figure 5 , this embodiment provides the following technical solutions:

[0031] The back ends of the two feeding barrels 11 are sealed and connected with a heat pipe 112. The back end of the vertical kiln 1 is provided with a smoke exhaust port 14, a filter screen 141 is installed in the smoke exhaust port 14, and a smoke exhaust chimney 142 is sealed and installed outside the smoke exhaust port 14. The smoke exhaust chimney 142 is sealed and connected with the heat pipe 112 through a smoke exhaust pipe 143.

[0032] A heat conduction cavity 122 is provided in the furnace wall of the discharge barrel 12, and heat dissipation fins 123 are equidistantly installed in the heat conduction cavity 122. A heat dissipation port is provided at the back end of the heat conduction cavity 122, and a heat dissipation pipe 124 is sealed and installed outside the heat dissipation port. The heat dissipation pipe 124 is sealed and connected to the heat conduction pipe 112 through an exhaust pipe 125. Exhaust fans 15 are installed in the exhaust chimney 142 and the heat dissipation pipe 124.

[0033] Specifically, when the raw materials are heat treated in the vertical kiln 1, high-temperature exhaust gas will be generated. At this time, the high-temperature exhaust gas is discharged from the smoke outlet 14 through the exhaust fan 15, filtered by the filter 141, and then passed through the smoke chimney 142 and the smoke exhaust pipe 143 in turn, and finally introduced into the feeding barrel 11 by the heat pipe 112 to remove the waste heat of the raw materials. When the fired clinker is discharged from the discharge pipe 13, it needs to be cooled down quickly because of its high temperature. At this time, the heat dissipation fins 123 absorb the temperature of the clinker surface and transfer it to the air in the heat conduction cavity 122. The exhaust fan 15 then guides the hot air in the heat conduction cavity 122 out and introduces it into the heat conduction pipe 112, and finally enters the feeding barrel 11 to preheat the raw materials. The clinker can be quickly cooled while the raw materials can be preheated to achieve the recovery of waste heat.

[0034] In order to solve the technical problem of how to use multiple energy sources in a coordinated manner, please refer to Figure 4-Figure 5 , this embodiment provides the following technical solutions:

[0035] An installation groove 16 is provided in the furnace wall of the vertical kiln 1, and a heating coil 161 is installed in the installation groove 16. The photoelectric conversion mechanism 2 includes a photovoltaic panel 21 and a battery 22. The photovoltaic panel 21 and the battery 22 are both installed on the top of the vertical kiln 1. The photovoltaic panel 21 is electrically connected to the battery 22 through a wire, and the battery 22 is electrically connected to the heating coil 161 through a wire.

[0036] Specifically, the photovoltaic panel 21 can absorb light energy and convert it into electrical energy, which is stored in the battery 22. The battery 22 then powers the heating coil 161 to heat the raw materials. This technology realizes the supply of thermal energy through photoelectric conversion, advocates the coordinated use of multiple energy sources, improves energy utilization efficiency, and can also solve the current shortage of fossil fuels.

[0037] Working principle: When the multi-energy synergistic utilization equipment of the clinker production line is in use, the raw materials are put into the feeding barrel 11 through the feeding port 111, and the raw materials are slowly and orderly fed into the vertical kiln 1 through the feeding barrel 11. At this time, the photovoltaic panel 21 absorbs light energy and converts it into electrical energy and stores it in the battery 22. The heating coil 161 is powered by the battery 22 to achieve the firing of the raw materials. At the same time, the generated high-temperature exhaust gas is discharged from the smoke exhaust port 14 and introduced into the feeding barrel 11, which can preheat the raw materials. When the fired clinker is transported from the discharge barrel 12, the heat dissipation fins 123 will absorb the heat energy on the surface of the clinker and transfer it to the air in the heat conduction cavity 122 to form hot air. The hot air is then discharged from the heat dissipation pipe 124 and introduced into the feeding barrel 11, which can quickly cool the clinker and preheat the raw materials to achieve the effect of waste heat recovery.
