[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-3 This utility model provides a technical solution: an integrated waste drying and crushing equipment, the main feature of which is that the drying and crushing processes of waste are integrated into one device to improve processing efficiency and reduce energy consumption. The device includes a drying drum 1, which is a horizontally set sealed cylinder to ensure that heat is not lost during the drying process and to prevent the entry of external impurities. On the inner wall of the drying drum 1, spiral conveying blades 2 are specially designed. These blades can effectively push the waste to move in the cylinder to ensure that the waste can be dried evenly.

[0028] A feed inlet 3 is provided at one end of the drying drum 1 to feed the waste material to be processed into the drum. At the other end, a discharge outlet 4 is provided to discharge the dried and crushed material. The design of the feed inlet 3 and the discharge outlet 4 makes the entire drying and crushing process smoother, and also facilitates the operator's monitoring and maintenance of the equipment.

[0029] The crushing mechanism 5 is another important component of this integrated equipment. It includes a main shaft 5-1 and multiple sets of crushing blades 5-2 mounted on the main shaft 5-1. The main shaft 5-1 runs through the entire drying drum 1 and is driven by a motor 6. The power and speed of the motor 6 can be adjusted as needed to accommodate different types and quantities of waste materials. The arrangement of the crushing blades 5-2 allows the waste material to be crushed during drying, further improving processing efficiency.

[0030] The hot air supply system is one of the key technologies of this equipment. It includes a hot air inlet 7, a hot air outlet 8, and a circulating fan 9. The hot air inlet 7 is located at the discharge end of the drying drum 1, while the hot air outlet 8 is located at the feed end, forming a counter-current hot air circulation system. This design ensures that the waste material is in contact with hot air throughout the drying process, thereby improving drying efficiency. The circulating fan 9 drives the hot air to circulate within the system, ensuring the continuity and uniformity of the hot air supply.

[0031] To further control the particle size of the crushed material, this equipment is specially designed with a first screen 10, which is located at the end of the drying drum 1. The aperture of the first screen 10 can be adjusted as needed to accommodate materials with different particle size requirements. Through screening by the screen 10, it can be ensured that the crushed material meets the predetermined particle size standard, satisfying the needs of subsequent processing or use.

[0032] Specifically, the spiral conveyor blade 2 and the crushing blade 5-2 are coaxially arranged and alternately on the main shaft 5-1. This allows for the synchronous operation of material conveying and crushing processes, thereby improving work efficiency.

[0033] Specifically, the crushing blade 5-2 adopts a detachable design. The crushing blade 5-2 is inserted into the main shaft 5-1, and a fixing rod 11 is provided in the axial position inside the main shaft 5-1. This fixing rod 11 passes through the crushing blade 5-2, ensuring the stability and safety of the crushing blade.

[0034] Specifically, the hot air supply system also includes a waste heat recovery unit 12, which is installed at the outlet end of the hot air outlet 8. Its presence can effectively recover and utilize the waste heat in the hot air, thereby improving energy efficiency.

[0035] Specifically, a second screen 13 is specially designed inside the hot air outlet 8. The main function of this second screen 13 is to block waste materials and ensure the cleanliness of the hot air, thereby improving the overall performance of the hot air supply system.

[0036] Specifically, the first screen 10 is designed to be detachable, which facilitates daily cleaning and maintenance. In addition, a vibrator 14 is provided on the outside of the drying drum 1. The function of the vibrator 14 is to transmit vibration to the first screen 10, which can effectively remove residual materials on the screen and ensure the efficient operation of the drying drum 1.

[0037] Working principle: Waste material enters through the feed inlet 3 and enters the drying drum 1.

[0038] During the drying process, inside the drying drum 1, the spiral conveyor blades 2 push the waste material along the drum's axial direction, while the hot air supply system blows hot air into the drum through the hot air inlet 7. The hot air and waste material flow in opposite directions, forming a counter-current hot air circulation, thereby improving heat exchange efficiency and accelerating the drying process of the waste material.

[0039] During the crushing process, as the waste material moves within the drying drum 1, it passes through the crushing mechanism 5, which consists of a main shaft 5-1 and multiple sets of crushing blades 5-2 mounted on the main shaft. The spiral conveyor blades 2 are coaxially arranged with the crushing blades 5-2 and alternately arranged on the main shaft 5-1, achieving synchronous material conveying and crushing. The crushed material undergoes particle size control through the first screen 10.

[0040] The crushing blade design features a detachable design for easy replacement and maintenance. The crushing blade is inserted into the main shaft 5-1 and secured by an internal fixing rod 11.

[0041] Hot air circulation and waste heat recovery: The hot air outlet 8 is equipped with a second screen 13 to block waste materials, while the waste heat recovery unit 12 recovers the waste heat from the hot air outlet 8, thereby improving energy utilization efficiency.

[0042] The screen vibrates. The first screen 10 is a detachable screen. A vibrator 14 is provided outside the drying drum 1. The vibrator transmits vibration to the first screen, which helps the material pass through the screen and prevents the screen from clogging.

[0043] In summary, this equipment achieves the drying and crushing of waste materials through the synchronous operation of the spiral conveyor blades and crushing mechanism within the drying drum. A hot air circulation system and waste heat recovery unit improve thermal efficiency, while a vibrating screen ensures that the particle size of the crushed material meets the requirements.
