[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0019] Please see Figure 1-3 A vibratory conveying system for ash and slag from a power plant boiler is disclosed. The system comprises a high-temperature vibratory conveyor 1, a boiler body 2, a slag cooling device 3, a bucket elevator 4, a screw conveyor 5, and a slag bin 6. The slag cooling device 3 includes a slag cooler and a slag storage box. The slag cooler has a slag inlet and a slag outlet, which are connected to the slag discharge outlet of the boiler body 2. The slag outlet is connected to the slag inlet of the slag storage box. A valve is installed at the slag outlet of the slag storage box, and the slag outlet of the slag storage box is connected to the inlet of the high-temperature vibratory conveyor 1. The high-temperature vibratory conveyor 1 is controlled by a controller and has a closed structure. The outlet of the high-temperature vibratory conveyor 1 is connected to the bucket elevator 4, and the outlet of the bucket elevator 4 is connected to the screw conveyor 5. The outlet of the screw conveyor 5 is connected to the slag bin 6, ultimately conveying the ash and slag into the slag bin 6.

[0020] The high-temperature resistant vibrating conveyor 1 is composed of a conveying trough 1.1, a trough frame 1.2, a pressure plate 1.3, a base frame 1.4, a main vibration spring 1.5, a guide leaf spring 1.6, a damping spring 1.7, a base 1.8, a vibrating motor 1.9, a motor base frame 1.10, and a connecting leaf spring 1.11.

[0021] The conveying trough 1.1 is fixed to the trough frame 1.2 by the pressure plate 1.3. The trough frame 1.2 is connected to the base frame 1.4 by the interlaced main vibration spring 1.5 and guide leaf spring 1.6. The vibration motor 1.9 is connected to the base frame 1.4 by the motor base frame 1.10 and the connecting leaf spring 1.11.

[0022] Among them, the bucket elevator 4 and the screw conveyor 5 are controlled by a controller, and the valve is controlled by the controller.

[0023] The damping spring 1.7 is located at the bottom of the high-temperature vibrating conveyor 1.

[0024] The motor base frame 1.10 is located on the right side of the vibratory motor 1.9.

[0025] The damping spring 1.7 is connected to the base 1.8.

[0026] The working principle and usage process of this utility model are as follows: During operation, two vibrating motors 1.9 serve as the excitation source. Using the self-synchronization principle, the two vibrating motors 1.9 rotate in opposite directions, causing the base frame 1.4 of the conveyor to reciprocate. Through the action of the main vibration spring 1.5 and the guide leaf spring 1.6, the upper conveying trough 1.1 is driven to vibrate, thereby achieving the purpose of conveying materials.

[0027] With vibration damping springs 1.7 and base 1.8, the inertial force transmitted from the base frame 1.4 to the foundation is very small, resulting in good vibration isolation, minimal requirements on the foundation, and very little noise.

[0028] Meanwhile, the entire system is a fully enclosed structure. Flexible connections are used between the high-temperature vibrating conveyors 1 and 4, between the bucket elevator 4 and the screw conveyor 5, and between the screw conveyor 5 and the slag bin 6 to ensure no ash leakage. Furthermore, the conveying trough 1.1 of the high-temperature vibrating conveyor 1 is made of NM450 wear-resistant plate to improve its wear resistance. The weight ratio of the base frame 1.4 of the high-temperature vibrating conveyor 1 to the weight of the conveying trough 1.1 and the trough frame is between 2 and 4, minimizing the inertial force transmitted from the base frame 1.4 to the foundation. Small size, good vibration isolation, minimal foundation requirements, and low noise; the vibratory motor 1.9 is mounted on the motor base frame 1.10. The ash and slag coming out of the ash cooler reach over 100 degrees Celsius. The motor base frame 1.10 is connected to the base frame 1.10 via a connecting leaf spring 1.11. The frame and the conveying trough 1.1 are separated by a guide leaf spring 1.6 and a main vibration spring 1.5. The temperature of the ash and slag has no effect on the vibratory motor. At the same time, the high-temperature resistant vibratory conveyor 1 can be arbitrarily spliced ​​to meet the requirements of vertical and horizontal arrangement, multi-point feeding, and long-distance conveying.
