Description

Technical Field

[0001] This utility model relates to the field of slag discharge machine technology, and in particular to a ram-type direct-drive slag discharge machine. Background Technology

[0002] A slag remover is a boiler slag removal device. The slag produced after coal combustion in the boiler is dragged out of the furnace using the slag remover to clear slag buildup.

[0003] The slag falls into the slag trough of the slag discharger and is pushed out through the discharge port by the pusher slide. The pusher slide is connected to an inner swing arm, an outer swing arm, and a hydraulic cylinder. The hydraulic cylinder pushes the inner swing arm, which in turn drives the outer swing arm, pushing the pusher slide. While transmitting the thrust from the hydraulic cylinder, the inner and outer swing arms also limit the swing path of the pusher swing arms, ensuring that the pusher slide pushes the slag out of the slag trough. This design results in a large number of swing arms, a complex structure, and significant losses during force transmission, increasing the cost and weight of the slag discharger. Furthermore, the swing arm structure includes several vulnerable parts, leading to high maintenance costs.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a ram-type direct-drive slag discharge machine to simplify the structure of the slag discharge machine.

[0006] The technical solution of this utility model is as follows:

[0007] A ram-type direct-connection slag discharge machine, comprising a frame, a slag trough, a pushing ram, a telescopic assembly, and a swing arm;

[0008] The frame supports the slag tank;

[0009] The pusher slide is installed inside the slag trough;

[0010] The telescopic assembly is rotatably disposed within the slag trough; the telescopic end of the telescopic assembly is connected to the pusher slide.

[0011] One end of the swing arm is rotatably connected to the slag trough; the other end of the swing arm is rotatably connected to the pusher slide.

[0012] The slag trough is provided with an inlet and an outlet; the telescopic component extends and retracts, driving the pusher slide to push the slag at the inlet to the outlet.

[0013] A further technical solution is that bearing seats are arranged opposite each other on both sides of the slag trough; a first rotating shaft is arranged between the two bearing seats; the first rotating shaft is arranged laterally; and the swing arm is rotatably connected to the slag trough through the first rotating shaft.

[0014] A further technical solution is that a second rotating shaft is rotatably connected to one end of the pusher slide near the telescopic component; the telescopic component is connected to the pusher slide through the second rotating shaft.

[0015] A further technical solution is that the swing arm is connected to the pusher slide via the second rotating shaft.

[0016] A further technical solution is that the telescopic assembly is provided in two sets, and both sets of the telescopic assembly are simultaneously connected to the pusher slide.

[0017] A further technical solution is that the swing arm is provided with two arms, one of which is connected to the pusher slide alone.

[0018] A further technical solution is that the telescopic end of the telescopic component is tilted downwards.

[0019] A further technical solution is that the fixed end of the telescopic component is hinged to the slag tank.

[0020] A further technical solution is that a push plate is provided at the end of the pusher slide away from the telescopic component, and the lower plate of the push plate contacts the bottom of the slag trough.

[0021] A further technical solution is that the telescopic component is a hydraulic cylinder.

[0022] The beneficial technical effects of this utility model are as follows:

[0023] This utility model discloses a direct-connection slag discharge machine with a telescopic assembly directly connected to the pushing slide. The telescopic assembly extends and retracts, driving the pushing slide to slide and push material within the slag trough. The slide is then connected to a swing arm, which restricts its movement path. This design, with the hydraulic cylinder directly connected to the pushing slide, eliminates intermediate connecting components such as the swing arm, enhancing system stability and reducing energy consumption. The simplified mechanical structure also facilitates disassembly and maintenance, reducing potential points of failure. Simultaneously, the direct connection of the hydraulic cylinder to the pushing slide reduces transmission extension, allowing the cylinder's action to be transmitted to the slide more quickly, improving work efficiency.

[0024] Furthermore, two sets of telescopic components are provided, and both sets are simultaneously connected to the material pusher slide. The two sets of telescopic components drive the material slide to move simultaneously, improving the pushing force and stability of the material slide during the movement process.

[0025] Furthermore, the telescopic end of the telescopic component is tilted downwards. This allows gravity to assist in the extension of the telescopic end, improving its working efficiency. Simultaneously, the tilted design reduces the horizontal space occupied by the telescopic component, making the slag discharger more compact. Attached Figure Description

[0032] Figure 1 This diagram shows the main structural view of the slide block direct-connection slag discharge machine of this utility model. Please refer to it. Figure 1The direct-drive slag discharge machine includes a frame 1, a slag trough 2, a pushing ram 7, a telescopic assembly 8, and a swing arm 5. The frame 1 supports the slag trough 2. The pushing ram 7 is housed within the slag trough 2. The telescopic assembly 8 is rotatably mounted within the slag trough 2. The telescopic end of the telescopic assembly 8 is connected to the pushing ram 7. One end of the swing arm 5 is rotatably connected to the slag trough 2. The other end of the swing arm 5 is rotatably connected to the pushing ram 7. The slag trough 2 has an inlet 21 and an outlet 22. The telescopic assembly 8 extends and retracts, driving the pushing ram 7 to push the slag material at the inlet 21 to the outlet 22. This design, with the hydraulic cylinder directly connected to the pushing ram 7, eliminates intermediate connecting components such as the swing arm 5, enhancing system stability and reducing equipment energy consumption. The simplified mechanical structure also facilitates disassembly and maintenance, reducing potential failure points. Simultaneously, the direct connection of the hydraulic cylinder to the pushing ram 7 reduces transmission extension, allowing the hydraulic cylinder's action to be transmitted to the ram more quickly, improving working efficiency.

[0033] Please refer to Figure 1 Bearing seats 3 are arranged opposite each other on both sides of the slag trough 2. A first rotating shaft 4 is arranged between the two bearing seats 3. The first rotating shaft 4 is arranged laterally. The swing arm 5 is rotatably connected to the slag trough 2 through the first rotating shaft 4. A second rotating shaft 6 is rotatably connected to one end of the pusher slide 7 near the telescopic component 8. The telescopic component 8 is connected to the pusher slide 7 through the second rotating shaft 6.

[0034] Preferably, the swing arm 5 is connected to the pusher slide 7 via the second pivot 6. The swing arm 5 and the telescopic assembly 8 share the second pivot 6, making the structure of the equipment more compact.

[0035] Figure 1 The diagram shows the main structural view of the slide block direct-connection slag discharge machine of this utility model. Figure 2 This diagram shows a top view of the ram-type direct-drive slag discharge machine of this invention. Please refer to it. Figure 1 and Figure 2 Two sets of telescopic components 8 are provided, and both sets of telescopic components 8 are simultaneously connected to the material pushing slide 7. The two sets of telescopic components 8 drive the material slide 7 to move simultaneously, improving the pushing force and stability of the material slide 7 during the movement process.

[0036] Preferably, two swing arms 5 are provided, and both swing arms 5 are connected to the pusher slide 7 to limit the movement path of the pusher slide 7.

[0037] More preferably, the telescopic end of the telescopic component 8 is inclined downwards. This allows gravity to assist in the extension of the telescopic end of the telescopic component 8, which helps improve the working efficiency of the telescopic component 8. At the same time, the inclined arrangement of the telescopic component 8 reduces the space occupied by the telescopic component 8 in the horizontal direction, making the structure of the slag discharger more compact.

[0038] Please refer to Figure 1The fixed end of the telescopic component 8 is hinged to the slag trough 2. This allows the angle of the telescopic component 8 to be adjusted to correspond to the position of the pusher slide 7 when the telescopic component 8 drives the pusher slide 7.

[0039] Preferably, a pusher plate 71 is provided at the end of the pusher slide 7 away from the telescopic component 8, and the lower plate of the pusher plate 71 contacts the bottom of the slag trough 2. The pusher plate 71 increases the area of ​​the slide plate end, thereby improving the efficiency of the slide plate in pushing the slag.

[0040] More preferably, the telescopic component 8 is a hydraulic cylinder. The hydraulic system can output a large force with a small size and weight, which facilitates driving the pusher slide 7 to push materials.

[0041] The specific workflow of this utility model is as follows:

[0042] When the slag discharger pushes material, slag is fed into the slag trough 2 through the feed inlet 21. The telescopic assembly 8 is then activated. The telescopic end of the telescopic assembly 8 extends, pushing the pusher slide 7. The pusher slide 7 slides within the slag trough 2, pushing the material until it flows out of the slag trough 2 through the discharge outlet 22. Then, the telescopic end of the telescopic assembly 8 retracts, pulling the pusher slide 7 back to its original position along the slag trough 2. During the sliding of the pusher slide 7, the swing arm 5 is driven by the pusher slide 7 to rotate around the bearing seat 3, and simultaneously pulls the telescopic slide, limiting its sliding path. During the operation of the telescopic assembly 8, slag is continuously fed into the feed inlet 21, replenishing the slag in the slag trough 2.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
