Description

Technical Field

[0001] This utility model relates to the field of feeding structures, and more specifically, to a feeding structure for RDF alternative fuel in cement kilns. Background Technology

[0002] In cement production, the choice of fuel and the efficiency of the feeding system have a significant impact on the stability and cost-effectiveness of the overall production process. Traditionally, cement kilns have mainly relied on coal as fuel. RDF (rejection-derived fuel), as a fuel converted from waste, has gradually become one of the preferred alternative fuels in the cement industry due to its renewable, low-carbon, and environmentally friendly characteristics.

[0003] However, due to the complex composition, uneven particle size, and high moisture content of RDF fuel, traditional feeding structures often cause fuel to adhere to the conveyor belt during transportation, leading to frequent blockages at the discharge port, which not only affects the continuity and stability of feeding.

[0004] Therefore, we have made improvements and proposed an RDF alternative fuel feeding structure for cement kilns. Utility Model Content

[0005] The purpose of this invention is to address the problem that fuel tends to adhere to the conveyor belt during the conveying process in existing feeding structures, leading to frequent blockages at the discharge port.

[0006] To achieve the above-mentioned objectives and improve the above-mentioned problems, this utility model provides a cement kiln RDF alternative fuel feeding structure, including a conveyor. The front end of the conveyor is provided with an installation component, the outside of the installation component is provided with a cleaning component, the bottom end of the installation component is provided with a connecting component, the inside of the connecting component is provided with a receiving component, both sides of the receiving component are provided with moving components, and the outside of the connecting component is provided with a transmission component.

[0007] As a preferred technical solution of this application, the conveyor includes a frame, and a conveyor belt is provided inside the frame.

[0008] As a preferred technical solution of this application, the installation assembly includes two connecting plates fixed to the front end of the frame, and an installation roller is rotatably provided between the two connecting plates. When the installation roller rotates, it works in conjunction with the cleaning component to clean the fuel on the conveyor belt.

[0009] As a preferred technical solution of this application, the cleaning component includes a cleaning brush, which is fixed to the outside of the mounting roller.

[0010] As a preferred technical solution of this application, the connecting member includes an installation bucket, which is fixed to the front of the bottom end of the conveyor and is inclined. The receiving and conveying member includes a connecting bucket that is slidably connected to the inside of the installation bucket.

[0011] As a preferred technical solution of this application, the moving component includes connecting blocks located on both sides of the connecting bucket. Openings are provided on both sides of the mounting bucket. The two connecting blocks are located inside the two openings and are fixedly connected to the connecting bucket. A sliding groove is provided on the side of the connecting block away from the connecting bucket. A transmission column is slidably provided inside the sliding groove. A No. 3 synchronous wheel is fixedly provided on the side of the transmission column away from the connecting bucket.

[0012] As a preferred technical solution of this application, the transmission assembly includes a motor fixed to the rear end of the mounting bucket. The output end of the motor is fixedly provided with a first synchronous pulley. The first synchronous pulley is located at the rear end of one of the third synchronous pulleys. The two ends of the mounting roller extend through two connecting plates to the top of both sides of the connecting bucket. The two ends of the mounting roller are fixedly provided with second synchronous pulleys. The first synchronous pulley is connected to the second and third synchronous pulleys on the same side by a belt. The second and third synchronous pulleys on the other side are also connected by belt drive.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the scheme of this application:

[0016] By setting up cleaning and receiving components, the moving components are driven by the transmission components to clean the fuel adhering to the conveyor belt. At the same time, the receiving components move back and forth to catch the cleaned fuel and send it to the bottom. This improves the stability and efficiency of feeding and solves the problem in the existing feeding structure where fuel easily adheres to the conveyor belt during the conveying process, causing frequent blockages at the discharge port.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1

[0028] Please refer to Figure 1 and Figure 4 A cement kiln RDF alternative fuel feeding structure includes a conveyor 1, with an installation component 2 at the front end of the conveyor 1. The installation component 2 can be a belt conveyor or a rubber belt conveyor. A cleaning component is provided on the outside of the installation component 2, and a connecting component is provided at the bottom end of the installation component 2. A receiving component is provided inside the connecting component. The receiving component is used to catch the fuel conveyed and cleaned down, and the fuel slides down to the bottom by tilting at an angle. Moving components 4 are provided on both sides of the receiving component. A transmission component 5 is provided on the outside of the connecting component. The transmission component 5 drives the receiving component to move back and forth through the moving components 4, shaking the fuel inside it evenly and avoiding blockage.

[0029] Furthermore, such as Figure 1As shown, the conveyor 1 includes a frame 11, and a conveyor belt 12 is provided inside the frame 11. Starting the frame 11 drives the conveyor belt 12 to transport fuel.

[0030] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the mounting assembly 2 includes two connecting plates 23 fixed to the front end of the frame 11. An mounting roller 21 is rotatably mounted between the two connecting plates 23. The mounting roller 21 contacts the front end of the conveyor belt 12. When the mounting roller 21 rotates, it works in conjunction with the cleaning component to clean the fuel on the conveyor belt 12, thereby removing the fuel adhering to the conveyor belt 12.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, the cleaning component includes a cleaning brush 22, which is fixed to the outside of the mounting roller 21. When the mounting roller 21 rotates, it drives the cleaning brush 22 to roll and brush the conveyor belt 12, thereby brushing off the fuel adhering to the conveyor belt 12.

[0032] Example 2

[0033] The cement kiln RDF alternative fuel feeding structure provided in Example 1 is further optimized, specifically, as follows: Figure 1 , Figure 2 and Figure 3 As shown, the connecting component includes a mounting bucket 31, which is used to connect with a connecting bucket 43. The mounting bucket 31 is fixed to the front of the bottom end of the conveyor 1. The mounting bucket 31 is inclined. The receiving component includes a connecting bucket 43 that is slidably connected inside the mounting bucket 31. The connecting bucket 43 is used to catch the fuel cleaned by the cleaning brush 22. At the same time, the fuel slides down when the mounting bucket 31 is inclined, so that it can fall accurately into the decomposition furnace.

[0034] The decomposition furnace is a key piece of equipment in a cement kiln system used to preheat raw materials and burn fuel. Here, RDF fuel can be mixed with preheated raw materials and rapidly decomposed and burned at high temperatures, releasing heat and the energy required for the chemical reaction.

[0035] Furthermore, such as Figure 2 , Figure 3 and Figure 4As shown, the moving component 4 includes connecting blocks 42 located on both sides of the connecting bucket 43. Openings 32 are provided on both sides of the mounting bucket 31. The two connecting blocks 42 are located inside the two openings 32 and are fixedly connected to the connecting bucket 43. The side of the connecting blocks 42 away from the connecting bucket 43 is provided with a sliding groove. The connecting blocks 42 cooperate with the transmission component 5 to make the connecting bucket 43 slide back and forth inside the mounting bucket 31. Under the reciprocating action of the connecting bucket 43, the fuel in the connecting bucket 43 is shaken and evenly distributed on the sliding path, reducing excessive accumulation of local fuel, and at the same time helping to clean the residue inside the connecting bucket 43.

[0036] A transmission column 54 is slidably installed inside the chute. A third synchronous wheel 53 is fixedly installed on the side of the transmission column 54 away from the connecting bucket 43. The transmission column 54 is installed at a position off-center from the third synchronous wheel 53, so that when the third synchronous wheel 53 rotates, it drives the connecting bucket 43 to slide back and forth on the mounting bucket 31 through the chute on the side of the connecting block 42. A fixing plate 33 is rotatably installed on the side of the third synchronous wheel 53 away from the connecting bucket 43 and is fixedly connected to the mounting bucket 31. The fixing plate 33 is used to support and install the third synchronous wheel 53.

[0037] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the transmission assembly 5 includes a motor 41 fixed to the rear end of the mounting bucket 31. A first synchronous pulley 51 is fixedly mounted at the output end of the motor 41. The first synchronous pulley 51 is located at the rear end of one of the third synchronous pulleys 53. The two ends of the mounting roller 21 extend through two connecting plates 23 to the upper sides of the connecting bucket 43. Second synchronous pulleys 52 are fixedly mounted at both ends of the mounting roller 21. When the second synchronous pulley 52 rotates, it drives the mounting roller 21 to rotate. The first synchronous pulley 51 is connected to the second synchronous pulley 52 and the third synchronous pulley 53 on the same side via a belt. The motor 41 is then started. 1. Its output end and the first synchronous pulley 51 rotate, thereby driving the second synchronous pulley 52 and the third synchronous pulley 53 to rotate via belt. This causes the transmission column 54 on the side of the third synchronous pulley 53 to slide inside the groove, pushing the connecting block 42 and the connecting bucket 43 to move. The second synchronous pulley 52 and the third synchronous pulley 53 on the other side are also connected by belt drive. When the third synchronous pulley 53 on the other side rotates, it drives the transmission column 54 to move inside the groove, driving the other side of the connecting bucket 43, so that the two sides of the connecting bucket 43 are more evenly stressed. The two belts are specifically synchronous belts.

[0038] Example 3

[0039] The cement kiln RDF alternative fuel feeding structure provided in Examples 1 and 2 has been further optimized, such as... Figure 1 and Figure 2As shown, the cleaning brush 22 and the mounting roller 21 are located below the front end of the conveyor belt 12, and the height of the cleaning brush 22 does not exceed the height of the conveyor belt 12. This allows the fuel conveyed on the conveyor belt 12 to fall naturally onto the cleaning brush 22, and the rolling of the mounting roller 21 will roll the fuel into the motor 41 to be caught. This prevents the fuel from falling between the conveyor belt 12 and the cleaning brush 22, which would affect the operating load of the mounting roller 21 and the conveyor belt 12.

[0040] The usage process of the cement kiln RDF alternative fuel feeding structure provided by this utility model is as follows:

[0041] When it is necessary to transport fuel on the conveyor belt 12, the frame 11 is started to make the conveyor belt 12 run and transport the fuel on the conveyor belt 12. At the same time, the motor 41 is started, which drives the first synchronous pulley 51 to rotate. The first synchronous pulley 51 drives the second synchronous pulley 52 and the third synchronous pulley 53 to rotate through the belt, which makes the mounting roller 21 and the cleaning brush 22 rotate. When the mounting roller 21 rotates, the second synchronous pulley 52 on the other side also rotates. Through the belt, the third synchronous pulley 53 on the other side also rotates. The third synchronous pulleys 53 on both sides drive the transmission column 54 to slide in the groove on the side of the motor 41, which in turn drives the connecting bucket 43 to slide back and forth on the mounting bucket 31.

[0042] At this time, the fuel conveyed from the conveyor belt 12 falls onto the cleaning brush 22. The rolling cleaning brush 22 carries the fuel into the connecting bucket 43. The inclined angle causes the fuel to slide down. At the same time, the cleaning brush 22 continuously brushes the front end of the conveyor belt 12, cleaning off the fuel adhering to the conveyor belt 12. The back-and-forth movement of the connecting bucket 43 makes the fuel inside more evenly distributed, catches the fuel cleaned off by the cleaning brush 22, and prevents fuel accumulation.
