Description

Technical Field

[0001] The invention relates to the technical field of dry slag machine conveyors, in particular to a conveying device capable of improving the slag discharge output of a dry slag machine. Background Art

[0002] At present, most boilers use air-cooled mechanical slag removal technology. The dry slag machine is arranged at the zero-meter position of the boiler room. The coke slag produced after the boiler combustion falls through the transition slag bucket to the stainless steel conveyor belt of the dry slag machine. The high-temperature slag is transported upward through the rotating stainless steel conveyor belt through the horizontal section and the climbing section (slope 22.5°) to the position of the machine head about 9 meters above the ground. The ash falls into the slag bin for storage, and the dry slag stored in the slag bin is loaded by the lower direct slag discharge system.

[0003] For energy saving, economic and environmental protection reasons, most thermal power generating units are involved in peak load regulation. Affected by the blending of coal, the boiler load changes frequently. During high load periods, the amount of slag generated surges, and the slag discharge capacity of the dry slag machine often reaches its upper limit, and the equipment runs at full load for a long time. In the long run, due to the limited slag discharge capacity of the dry slag machine and long-term overload operation, the equipment loss increases, the defects increase, the health level drops sharply, and the service life is seriously shortened; at the same time, it also affects the safe and stable operation of the unit at all times.

[0004] To this end, the present invention proposes a conveying device that can improve the slag discharge output of a dry slag machine. The slag discharge capacity of the dry slag machine is improved by modifying and optimizing the steel conveyor belt, thereby improving the health level of the equipment and extending the service life of the dry slag machine.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1, reference Figures 1 to 4, is the first embodiment of the present invention, which provides a conveying device that can improve the slag discharge output of a dry slag machine, including a conveying mechanism 100, and a supporting mechanism 200 arranged on the conveying mechanism 100, and a pushing piece 300 is arranged on the supporting mechanism 200; in this embodiment, a plurality of supporting mechanisms 200 are arranged on the conveying mechanism 100, and the operation of the conveying mechanism 100 can drive the supporting mechanism 200 to move, and then drive the pushing piece 300 on the supporting mechanism 200 to move. The pushing piece 300 hinders the slag, thereby improving the slag discharge efficiency and avoiding side slipping caused by tilting when the slag is conveyed upward.

[0036] The pusher 300 includes a pusher plate 301 disposed on the supporting mechanism 200. In the present embodiment, the pusher plate 301 and the surface of the supporting mechanism 200 are vertically arranged. The pusher plate 301 can block the slag during transportation, thereby pushing the slag upward.

[0037] Specifically, the side of the push plate 301 is provided with a restraining side 302. In this embodiment, the restraining side 302 is provided on both sides of the push plate 301, which can increase the amount of slag supported by the push plate 301, prevent the slag from sliding from the side, and thus improve the load capacity.

[0038] Furthermore, a bevel cut 303 is provided on the restraining side 302. In the present embodiment, the bevel cut 303 can facilitate the over-stacked slag to fall through the gaps between the pushing members 300 during inclined transportation, thereby avoiding excessive load on a certain part.

[0039] Example 2, reference Figure 1 to Figure 4 , which is the second embodiment of the present invention. Different from the previous embodiment, the supporting mechanism 200 includes a supporting plate 201, and the supporting plate 201 is a C-shaped structure with an opening facing upward. In this embodiment, the C-shaped supporting plate 201 can better receive the fallen material residues, prevent the material residues from sliding from both sides of the supporting mechanism 200, and improve the effect of material receiving and material retention.

[0040] Specifically, an outer groove 202 and an inner groove 203 are provided on the support plate 201. In the present embodiment, the outer groove 202 and the inner groove 203 are respectively provided on both sides of the support plate 201. Due to the provision of the outer groove 202 and the inner groove 203, adjacent support plates 201 can be staggered and overlapped with each other, thereby improving the effect of receiving fallen slag, thereby preventing the slag from falling from the gap between the support plates 201, and facilitating the overlap of the support plates 201 at the curved parts.

[0041] Furthermore, an inclined surface 204 is provided in the inner groove 203; the depth of the inner groove 203 and the outer groove 202 are both greater than half of the thickness of the support plate 201. In the present embodiment, since the outer groove 202 and the inner groove 203 are overlapped in sequence, it is inevitable that slag will fall into the gap between the support plates 201. The setting of the inclined surface 204 can facilitate the falling of slag, avoid the deformation of the overlapping parts between the support plates 201 due to the extrusion of slag, and increase the service life of the equipment. The depth of the inner groove 203 and the outer groove 202 are both greater than half of the thickness of the support plate 201, which means that there is always a gap between the two adjacent support plates 201 to provide slag for the falling of slag, and further avoid the serious wear and deformation of the stripping plate 201 caused by the extrusion of the support plate 201 by the slag, thereby improving the service life of the equipment.

[0042] The rest of the structure is the same as that of Example 1.

[0043] Example 3, reference Figure 1 to Figure 4 , which is the third embodiment of the present invention. Different from the previous embodiment, a plurality of pushers 300 are provided above each supporting plate 201, and the plurality of pushers 300 are evenly distributed on the supporting plate 201. In this embodiment, the provision of the plurality of pushers 300 can enhance the supporting effect of each supporting mechanism 200 during inclined conveying, and the evenly distributed provision can maintain a gap between each pusher 300, so that excess material residue can be discharged to the lower supporting mechanism 200, which can make each supporting mechanism 200 receive materials more evenly and each part bears the load evenly, making the equipment more stable when working.

[0044] Specifically, the evenly distributed support plates 201 are staggered along the length direction of the support plates 201. In the present embodiment, after the support plates 201 are staggered, it is possible to ensure the supporting effect of the supporting mechanism 200 while providing a larger gap space for excess material to fall from the gap between the pushing members 300 to the top of the lower supporting mechanism 200, thereby avoiding accumulation when there is too much material.

[0045] Furthermore, the conveying mechanism 100 includes a driving wheel 101 and a chain 102 disposed outside the driving wheel 101. In this embodiment, the driving wheel 101 is connected to a driving device, and the driving wheel 101 can rotate to drive the chain 102 to move.

[0046] A fixed plate 103 is provided on the chain 102, a fixed shaft 104 is provided on the fixed plate 103, and the support plate 201 is connected to the fixed plate 103 via the fixed shaft 104; in this embodiment, a fixed plate 103 is provided on each section of the chain 102, and each fixed plate 103 is fixedly connected to the support plate 201 via multiple fixed shafts 104.

[0047] The support plate 201 is arranged away from the fixed plate 103. Since the support plates 201 are arranged away from each other, each support plate 201 can have a larger volume, reducing the number of support plates 201, thereby reducing the gap between the support plates 201 and reducing the falling of material residues. At the same time, since the number of stripping plates 201 located at the driving wheel 101 is reduced, when moving to the driving wheel 101, the gap between two adjacent support plates 201 will increase, which is convenient for the material stuck in the gap between the support plates 201 to fall.

[0048] The rest of the structure is the same as that of Example 2.

[0049] It should be noted that the pusher 300 and the supporting mechanism 200 are made of the same material, which is wear-resistant stainless steel. When the supporting plate 201 moves forward at a uniform speed, the ash produced by the combustion in the furnace is evenly distributed on the supporting plate 201. In the climbing section of the steel conveyor belt, the coke blocks between adjacent pusher plates 301 can also be evenly distributed. The pusher plate 301 can successfully intercept the coke blocks that are easy to slide down and roll due to insufficient friction, and successfully send them into the slag bin. At the same time, during the deep peak regulation of the boiler and the peak high load period, the coke slag produced can also be carried to the slag bin at one time, greatly improving the slag carrying capacity of the conveyor belt. Improve the stability and safety of the slag removal system.

[0050] It has a good effect in actual application at the production site. It can effectively transport the generated ash to the slag bin at one time, save energy and reduce consumption, be environmentally friendly and economical, reduce equipment wear, increase equipment service life, and continuously improve the health level of equipment, laying a good equipment foundation for the long-term safe and stable operation of the slag removal system and boiler.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
