Therefore, a dust removal and conveying system is generally used to process and convey these slag and dust. Among them, a dust conveying device is used to convey the slag. At present, a scraper conveyor and a bucket elevator are commonly used in combination.

[0003] For example, in Chinese Patent Application CN107892134B, a scraper conveyor is provided with a housing, which is divided into a head, a tail and an intermediate section connecting the head and the tail. The upper part of the intermediate section is provided with a feed inlet. A head sprocket and a tail sprocket are respectively arranged at the head and the tail. A scraper chain is sleeved on the head sprocket and the tail sprocket. The front and rear ends of the scraper chain are respectively provided with a front material outlet and a rear material outlet.

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] The "left", "right", "front", "rear", "upper" and "lower" mentioned in the following description are oriented in the perspective direction of the front view.

[0035] Example 1: In some embodiments, referring to the Figures 1 - 8 drawings of the specification, a dust conveying device with self-lubricating function includes a conveying device 1 and a lifting device 2;

[0036] The conveying device 1 includes a conveying component 11 for material conveying, a tensioning component 12 for adjusting the chain tightness of the conveying component 11, and an automatic lubricating component 13 for automatically lubricating the chain of the conveying component 11. The tensioning component 12 and the automatic lubricating component 13 are installed on the conveying component 11, and the conveying component 11 is connected to the lifting device 2;

[0037] The automatic lubricating component 13 includes a heat-conducting oil outlet component and a lubricating auxiliary component. The heat-conducting oil outlet component is connected to the conveying component 11, and the lubricating auxiliary component is connected to the heat-conducting oil outlet component.

[0038] When the dust conveying device with self-lubricating function is in normal use, the conveying component 11 conveys the material to the lifting device 2. At the same time, the tensioning component 12 tensions the chain of the conveying component 11. When the chain of the conveying component 11 runs, it generates heat by friction with the heat-conducting oil outlet component, melting the grease in the heat-conducting oil outlet component and triggering its flow. Along with the movement of the chain, the lubricating auxiliary component presses the flowing grease to the part between two chain links, completing automatic lubrication. Through the setting of the heat-conducting oil outlet component, the flow of the grease is triggered by frictional heat, realizing automatic lubrication. At the same time, the leakage of grease during the shutdown state is reduced. With the setting of the lubricating auxiliary component, the grease can be accurately applied to the appropriate position, improving the lubrication effect.

[0039] Example 2: In some embodiments, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , as a preferred embodiment of the present invention, the conveying component 11 includes a scraper conveyor 111 and a discharge box 112. The discharge port of the scraper conveyor 111 is fixedly connected to the discharge box 112. The inner side of the discharge box 112 is inclined. The discharge box 112 is connected to the lifting device 2. The scraper conveyor 111 is connected to the tensioning component 12 and the heat-conducting oil outlet component.

[0041] The heat-conducting oil outlet component includes a lubrication bin 1301, a limit groove box 1302, two slide bars a 1303, two springs a 1304, and a heat-conducting plate 1305. The lubrication bin 1301 and the limit groove box 1302 are fixedly installed at the upper end of the housing of the scraper conveyor 111. The lower discharge port of the lubrication bin 1301 passes through the limit groove box 1302 and extends to the inside of the limit groove box 1302. The lubrication bin 1301 is fixedly connected to the limit groove box 1302. The two slide bars a 1303 are arranged front and back and fixedly installed at the upper end of the heat-conducting plate 1305. The slide bars a 1303 are slidably connected to the limit groove box 1302. The two springs a 1304 are sleeved outside the two slide bars a 1303 and fixedly connected to the limit groove box 1302 and the heat-conducting plate 1305. The heat-conducting plate 1305 is located inside the limit groove box 1302. The lower end of the heat-conducting plate 1305 is in contact connection with the chain of the scraper conveyor 111. The lubrication auxiliary component is installed inside the limit groove box 1302. A U-shaped groove is opened at the lower end of the limit groove box 1302 for limiting the chain of the scraper conveyor 111. The lower end of the limit groove box 1302 is in fitting and sliding connection with the chain of the scraper conveyor 111.

[0042] The lubrication auxiliary component includes a slide bar b 1306, a spring b 1307, a lower pressing plate 1308, a limit block 1309, and two rollers 1310. The lower end of the slide bar b 1306 is fixedly connected to the lower pressing plate 1308. The slide bar b 1306 is in limit sliding connection with the limit groove box 1302. The slide bar b 1306 is hexagonal. The spring b 1307 is sleeved outside the slide bar b 1306 and fixedly connected to the limit groove box 1302 and the lower pressing plate 1308. The limit block 1309 is fixedly installed inside the limit groove box 1302 and is in contact connection with the lower pressing plate 1308. The two rollers 1310 are arranged front and back and rotatably installed at the lower left end of the lower pressing plate 1308. A convex block is fixedly arranged at the lower right end of the lower pressing plate 1308. The chain of the scraper conveyor 111 is composed of multiple chain links. One end of the chain link of the scraper conveyor 111 facing the moving direction is the wide end, and the other end is the narrow end. The wide end is arranged in an arc shape for cooperation with the rollers 1310.

[0043] The blanking auxiliary component 14 includes an air inlet pipe 141 and multiple air nozzles 142. The air inlet pipe 141 is fixedly installed inside the housing of the scraper conveyor 111. The air inlet pipe 141 is located above the discharge port of the scraper conveyor 111. The multiple air nozzles 142 are connected and fixedly installed at the lower end of the air inlet pipe 141. The air nozzles 142 are arranged facing the discharge port direction of the scraper conveyor 111. One end of the air inlet pipe 141 is communicated with a gas supply device.

[0044] When the ash conveying equipment with self-lubricating function is in normal use, materials are conveyed to the discharge box 112 through the scraper conveyor 111. The spring tensioner 121 continuously applies a downward force to the chain of the scraper conveyor 111, keeping the chain of the scraper conveyor 111 in a tensioned state. The lubricating grease is stored in the lubricating bin 1301. Under the action of gravity, the lubricating grease slowly drops onto the heat conducting plate 1305. The spring a 1304 pushes the heat conducting plate 1305 to make it closely fit with the chain of the scraper conveyor 111. The operation of the chain of the scraper conveyor 111 generates heat by rubbing against the heat conducting plate 1305. The lubricating grease on the heat conducting plate 1305 is melted by the heat and flows along the heat conducting plate 1305 onto the chain of the scraper conveyor 111. The roller 1310 rolls along the wide end of the link of the scraper conveyor 111. When the narrow end of the link moves below the roller 1310, the spring b 1307 pushes the lower pressing plate 1308 downward. The lower pressing plate 1308 pushes the lubricating grease to the connection of the two links to complete lubrication. The limit block 1309 blocks the lower pressing plate 1308 to prevent the lower pressing plate 1308 from fitting the chain of the scraper conveyor 111. At the same time, the lower U-shaped groove of the limit groove box 1302 limits the running track of the chain. Start the air supply equipment. The air supply equipment sprays the gas from the air jet nozzle 142 through the air inlet pipe 141. The gas accurately sends the materials into the discharge box 112 and cleans the scraper of the scraper conveyor 111 at the same time. Through the limitation of the chain by the limit groove box 1302, it is avoided that the chain shakes and derails during operation, restricting the lateral deviation of the chain. Through the setting of the air inlet pipe 141, the materials are accurately sent into the discharge box 112, avoiding the accumulation of materials at the right end of the scraper conveyor 111 and being difficult to clean. At the same time, the scraper of the scraper conveyor 111 can be cleaned to reduce material residue.

[0045] Embodiment 3: In some embodiments, as Figures 1 - 8 shown, as a preferred embodiment of the present invention, the lifting device 2 includes a lifting component 21 and a tensioning and stabilizing component 22. The lifting component 21 is connected to the discharge box 112, and the tensioning and stabilizing component 22 is connected to the lifting component 21.

[0046] The lifting component 21 includes a bucket elevator 211 and an arc-shaped bottom plate 212. The outer shell of the bucket elevator 211 is fixedly connected to the discharge box 112. The feed inlet of the bucket elevator 211 is communicated with the discharge outlet of the discharge box 112. The arc-shaped bottom plate 212 is fixedly installed inside the outer shell of the bucket elevator 211. The upper end of the arc-shaped bottom plate 212 fits the hopper of the bucket elevator 211.

[0047] The tensioning and stabilizing assembly 22 includes a sliding frame 221, a tensioning roller 222, a tensioning box 223, a threaded rod 224, a tension spring 225 and a limiting and stabilizing component. The sliding frame 221 is installed in a limited and sliding manner inside the outer shell of the bucket elevator 211. The tensioning roller 222 is rotatably installed inside the sliding frame 221. The tensioning roller 222 is in contact connection with the chain of the bucket elevator 211. The tensioning box 223 is fixedly installed outside the outer shell of the bucket elevator 211. One end of the threaded rod 224 is fixedly connected to the end of the sliding frame 221 away from the hopper of the bucket elevator 211. The other end of the threaded rod 224 passes through the tensioning box 223. Two nuts are threadedly connected to the outer side of the threaded rod 224. The two nuts are respectively located on one side of the sliding frame 221 and the tensioning box 223 away from the hopper of the bucket elevator 211. The tension spring 225 is sleeved on the outer side of the threaded rod 224. The tension spring 225 is fixedly connected to one nut and the tensioning box 223. The sliding frame 221 is connected to the limiting and stabilizing component. The upper end of the tensioning box 223 is fixedly installed with an end cover by bolts in a sealed manner.

[0048] The limiting and stabilizing component includes a sliding rod c226, two spring c227, two sliding plates 228 and two limiting wheels 229. The sliding rod c226 is fixedly installed inside the sliding frame 221. The two sliding plates 228 are symmetrically arranged front and back and are slidably installed on the sliding rod c226. Two limiting wheels 229 are rotatably installed inside the two sliding plates 228. The limiting wheels 229 are in contact connection with the chain of the bucket elevator 211. The two tension springs 225 are symmetrically arranged front and back and are sleeved on the outer side of the sliding rod c226. The tension springs 225 are respectively fixedly connected to the sliding frame 221 and the sliding plate 228.

[0049] When the ash conveying equipment with self-lubricating function is in normal use, materials enter the bucket elevator 211 along the discharge box 112. The hoppers of the bucket elevator 211 convey the materials upward. Some materials that do not directly enter the hopper fall onto the arc-shaped bottom plate 212 and are shoveled up by the subsequent hoppers for conveying. During the operation of the bucket elevator 211, the tension spring 225 pulls the sliding frame 221. The sliding frame 221 drives the tensioning roller 222 to pull the chain of the bucket elevator 211 to keep it taut. At the same time, the spring c227 pushes the sliding plate 228 to move towards the middle along the sliding rod c226. The sliding plate 228 drives the limiting wheel 229 to fit against the chain of the bucket elevator 211 for clamping. During the operation of the chain, it drives the limiting wheel 229 to roll, and through the tension spring 225, it drives the sliding frame 221 and the tensioning roller 222 to pull the chain towards the side, so that the chain always remains taut, so that the lower hopper of the bucket elevator 211 can always be kept in contact with the arc-shaped bottom plate 212, avoiding the problem of material accumulation caused by the need to adjust the position of the sprocket of the bucket elevator 211, resulting in a large space below the bucket elevator 211.

[0050] 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
