[0002] Cement is a powdery hydraulic inorganic binder that forms a paste when mixed with water. It can harden in air or water and can firmly bind materials such as sand and stone together. A cement kiln is usually required when firing cement.

[0003] A search revealed that the announcement number is CN211823783U, and the name is a cement kiln, including a cement kiln processing chamber. Through research and analysis, it was found that although it has the advantages of low noise and low failure rate, it also has the following disadvantages to a certain extent.

[0004] For example, the device cannot treat and recycle the generated waste gas during use, which not only pollutes the environment but also wastes the heat in the flue gas, making it difficult to ensure sustainable development and normal use. In order to solve the above technical problems, we have designed a cement kiln that can realize the co-combustion of waste tire powder and low-calorific-value bituminous coal. Utility Model Content

[0005] The purpose of this invention is to provide a cement kiln that can achieve co-combustion of waste tire powder and low-calorific-value bituminous coal, which has the advantage of treating waste gas. This solves the problem that the device cannot treat and recycle the waste gas produced during use, which not only pollutes the environment but also wastes the heat in the flue gas, making it difficult to ensure sustainable development and normal use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cement kiln capable of co-combusting waste tire powder with low-calorific-value bituminous coal, comprising a base, a cement kiln body installed on the left side of the top of the base, a flue pipe connected to the top of the cement kiln body, a flue pipe connected to the top of the flue pipe, a dust removal component installed in the inner cavity of the flue pipe, a mounting base welded to the top of the flue pipe, a sealing plate connected to the bottom of the flue pipe, a filter shell welded to the surface of the sealing plate, a water tank connected to the right side of the top of the base by bolts, an air pump connected to the top of the base by bolts, a spiral tube connected to the bottom of the filter shell, a storage tank connected to the rear side of the water tank by bolts, and a filter plate installed in the inner cavity of the filter shell by bolts.

A rotating rod is provided through the right side of the fixed frame, and a connecting frame is welded to the surface of the rotating rod. A scraper is bolted to the surface of the connecting frame. A motor is bolted to the top of the mounting base. A second pulley is fixedly sleeved on the drive shaft of the motor. A first pulley is fixedly sleeved on the right side of the rotating rod. A drive belt is drivingly connected between the second pulley and the first pulley.

[0008] Preferably, a positioning plate is welded to the top of the inner cavity of the smoke guide pipe, and the left side of the rotating rod is rotatably connected to the positioning plate.

[0009] Preferably, the top of the smoke guide pipe is connected to a protective shell, and the second pulley is located in the inner cavity of the protective shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model base uses waste tire powder and low-calorific-value bituminous coal to burn cement. The waste gas generated during the burning process flows into the flue pipe through the exhaust pipe and is then passed into the filter shell through the flue pipe. Impurities in the waste gas are filtered out by the filter plate. The filtered impurities fall into the storage box for collection under the action of gravity. The filtered gas flows into the spiral tube and the heat in the gas is transferred into the water in the water tank through the spiral tube to collect the heat in the flue gas.

[0015] After prolonged use, the inner wall of the flue will accumulate a lot of dust. The motor's drive shaft drives the rotating rod, the first belt pulley, the second belt pulley, and the drive belt to rotate. The rotating rod drives the connecting frame and the scraper to rotate. The scraper sweeps the dust off the inner wall of the flue, facilitating the normal operation of the device. Attached Figure Description

A rotating rod 6 is provided through the right side of the fixing frame 5. A connecting frame 7 is welded to the surface of the rotating rod 6. By providing the connecting frame 7, it is easy to connect the rotating rod 6 and the scraper 8, so that the rotating rod 6 can drive the scraper 8 to rotate. The scraper 8 is bolted to the surface of the connecting frame 7. A motor 11 is bolted to the top of the mounting base 10. A second pulley 12 is fixedly sleeved on the drive shaft of the motor 11. A first pulley 9 is fixedly sleeved on the right side of the rotating rod 6. A drive belt 13 is connected between the second pulley 12 and the first pulley 9.

[0023] Please see Figure 1 and Figure 2 A positioning plate is welded to the top of the inner cavity of the smoke guide pipe 4. By setting the positioning plate, the rotating rod 6 can be positioned and rotated stably. The left side of the rotating rod 6 is rotatably connected to the positioning plate.

[0024] Please see Figure 1 and Figure 2 The top of the smoke guide pipe 4 is connected to a protective shell 14. By setting the protective shell 14, the second pulley 12 and the drive belt 13 can be protected, and the second pulley 12 and the drive belt 13 can be effectively prevented from being damaged. The second pulley 12 is located in the inner cavity of the protective shell 14.

[0025] Please see Figure 1 and Figure 3 The rear side of the filter housing 16 is connected to the storage box 18 through a pipe. The rear side of the storage box 18 is connected to a drain pipe, and a first pipe cover is fitted on the rear side of the drain pipe. By setting the drain pipe, it is easy to discharge the debris inside the storage box 18. By setting the first pipe cover, it is possible to effectively prevent the debris from leaking out of the storage box 18.

[0026] Please see Figure 1 The rear side of the air pump 21 is connected to the spiral tube 19 through a pipe. The air outlet pipe of the air pump 21 is threaded with a filter cover.

[0028] In use, the device is controlled by an external controller. The base 1 is used to burn cement by mixing waste tire powder and low-calorific-value bituminous coal. The exhaust gas generated during the burning process flows into the flue pipe 4 through the exhaust pipe 3. The exhaust gas is then passed into the filter shell 16 through the flue pipe 4. The filter plate 17 filters out impurities in the exhaust gas. The filtered impurities fall into the storage box 18 for collection under the action of gravity. The filtered gas flows into the spiral tube 19. The spiral tube 19 transfers the heat in the gas into the water in the water tank 20. After long-term use, a lot of dust will be attached to the inner wall of the flue pipe 4. The drive shaft of the motor 11 drives the rotating rod 6, the first belt pulley 9, the second belt pulley 12 and the drive belt 13 to rotate. The rotating rod 6 drives the connecting frame 7 and the scraper 8 to rotate. The scraper 8 sweeps off the dust from the inner wall of the flue pipe 4.

[0029] In summary, this cement kiln, which enables the co-combustion of waste tire powder and low-calorific-value bituminous coal, solves the problems of the previous device's inability to treat and recover the generated waste gas during operation. This was achieved through the use of filter shell 16, filter plate 17, storage box 18, spiral tube 19, water tank 20, air pump 21, and dust removal component 22. These problems not only caused environmental pollution but also wasted heat in the flue gas, hindering sustainable development and normal operation.
