Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. Embodiment

[0021] Please refer to Figures 1-4 , in the embodiment of the present invention, a downward ash water-cooled spiral conveying structure for a boiler superheater includes: a conveying box 1, with a feed inlet and a discharge outlet respectively opened at the top and bottom of the conveying box 1;

[0022] An auger screw 2, which is rotatably installed between the two sides of the inner wall of the conveying box 1;

[0023] A crushing box 3, which is fixedly installed on the top of the conveying box 1. Therefore, a feed inlet is provided at the top of the crushing box 3. The crushing box 3 is in communication with the top of the conveying box 1, and a crushing assembly 4 for crushing ash slag is installed in the crushing box 3;

[0024] A driving motor 5, which is fixedly installed on one side of the conveying box 1, and the output end of the driving motor 5 is fixedly connected to one end of the auger screw 2. The lengths of the auger screw 2 and the conveying box 1 are set according to the actual required length.

[0025] Specifically, the ash and slag generated by the boiler enter the crushing box 3 through the feed inlet at the top of the crushing box 3. The crushing box 3 is fixedly installed on the top of the conveying box 1 and is interconnected with the top of the conveying box 1, ensuring that the ash and slag can smoothly enter the crushing box 3. Inside the crushing box 3, a crushing component 4 is installed, which is designed to crush larger ash and slag into smaller particles. Smaller particles are easier to handle in the subsequent conveying process and are also convenient for subsequent ash and slag treatment and utilization. Crushing the ash and slag avoids wear on the auger screw 2 and the conveying box 1 caused by its large volume, and facilitates the conveying of the ash and slag, preventing blockage and affecting the working efficiency of the conveying. The auger screw 2 is rotatably installed between the two sides of the inner wall of the conveying box 1. The driving motor 5 is fixedly installed on one side of the conveying box 1, and its output end is fixedly connected to one end of the auger screw 2. When the driving motor 5 is started, it provides power for the auger screw 2 to rotate, thereby driving the entire conveying process. After being conveyed by the auger screw 2, the crushed ash and slag finally reach the discharge port at the bottom of the conveying box 1 and are discharged from here, completing the entire conveying process.

[0026] As Figures 2-3 shown, in this embodiment, the crushing component 4 includes two crushing wheels 41 that are symmetrically distributed and rotatably installed between the two sides of the inner wall of the crushing box 3. One end of each of the two crushing wheels 41 penetrates through the crushing box 3 and extends to the outside. A gear 42 is fixedly installed at one end of each of the two crushing wheels 41, and the two gears 42 are meshed with each other. A linkage component 43 is installed between one end of one of the crushing wheels 41 and the auger screw 2.

[0027] In this embodiment, the crushing component 4 consists of two crushing wheels 41, which are symmetrically installed between the two sides of the inner wall of the crushing box 3. This symmetrical layout helps to provide uniform crushing force, ensuring effective and consistent crushing treatment of the ash and slag inside the crushing box. One end of each crushing wheel 41 is designed to penetrate through the crushing box 3 and extend to the outside, and the external extension part can be used to fix the gear 42. The meshing of the gears 42 ensures the synchronous rotation between the two crushing wheels 41. A linkage component 43 is installed between one end of one of the crushing wheels 41 and the auger screw 2. The function of the linkage component 43 is that when the driving motor 5 is started, it transmits the rotational motion of the auger screw 2 to one of the crushing wheels 41 to make it rotate, and then through the meshing of the two gears 42, the two crushing wheels 41 rotate synchronously to crush the ash and slag, thereby realizing the linkage operation of crushing and conveying. Through the design of the crushing component 4, the entire ash and slag water-cooled spiral conveying structure under the boiler superheater realizes the efficient coordination of crushing and conveying, improves the efficiency of ash and slag treatment, reduces equipment wear, and is also convenient for subsequent treatment and utilization of the ash and slag.

[0028] As Figures 2-3As shown, in this embodiment, the linkage assembly 43 includes a first pulley 431 fixedly installed at one end of one of the crushing wheels 41. One end of the auger screw 2 is fixedly sleeved with a second pulley 432, and a belt is drivingly installed between the first pulley 431 and the second pulley 432.

[0029] In this embodiment, when the auger screw 2 rotates, it can drive the second pulley 432 to rotate, and through belt drive, it can drive the first pulley 431 to rotate, thus realizing the rotation of the crushing wheel 41.

[0030] As Figure 1 shown, in this embodiment, two support plates 6 are fixedly installed on both sides of the conveying box 1, and shock pads 7 are fixedly installed at the bottoms of the support plates 6.

[0031] Specifically, the arrangement of the support plates 6 and the shock pads 7 is used to reduce the vibration and noise of this equipment, facilitating the normal operation of the equipment. Embodiment

[0032] On the basis of Embodiment 1, in order to facilitate the centralized collection of the dust generated during conveying, avoid its random dispersion, polluting the surrounding environment and being inhaled by the staff, which is harmful to their physical health.

[0033] As Figure 1 shown, in this embodiment, a collection box 8 is fixedly installed on the top of the conveying box 1. A suction pump 9 is fixedly inserted on one side of the collection box 8. A suction hood 10 is fixedly inserted on the top of the conveying box 1. A pipeline is communicated between the suction hood 10 and the collection box 8. A box door is provided on the collection box 8, and a filter cloth 101 is provided at the suction port of the suction pump 10 to prevent dust from entering the suction pump 10 and causing damage.

[0034] Specifically, when the suction pump 9 is started, the suction force generated by it passes through the collection box 8, the pipeline and the suction hood 10 to absorb the dust raised during conveying in the conveying box and enter the collection box 8 for centralized collection, avoiding its random dispersion to the external environment through the inlet and outlet, polluting the surrounding environment and being inhaled by the staff, which is harmful to their physical health.

[0035] As Figure 2 shown, in this embodiment, a closing plate 11 is slidably installed at the feeding port on the top of the crushing box 3. An electric push rod 12 is fixedly installed on the crushing box 3, and the telescopic end of the electric push rod 12 is fixedly connected to the closing plate 11.

[0036] When the electric push rod 12 is started, the telescopic movement of its telescopic end can realize the movement of the closing plate 11 to open and close the feeding port on the top of the crushing box 3, avoiding the random dispersion of the dust generated during crushing.
