Description

Technical Field

[0001] This application relates to the technical field of slag dischargers, and particularly to an automatic slag discharging and anti-blocking device and a slag discharger. Background Art

[0002] A slag discharger is a boiler slag discharging device. The slag produced after coal burns in the boiler is pushed by the grate to the slag storage pit and is dragged out of the furnace by the slag discharger to dredge the slag accumulation.

[0003] After the slag enters the slag barrel of the slag discharger, it is pushed by the slipper in the slag discharger and discharged from the discharge port. To ensure that the slipper cleans the slag in the slag barrel, the end of the slipper needs to fit the inner wall of the slag barrel. After the slag discharger works for a long time, slag will adhere to the inner wall of the slag barrel. At this time, the slipper reciprocates along the inner wall of the slag barrel, and it is inevitable that the slipper will scrape some slag to the side far from the discharge port. These slag that are far from the discharge port accumulate and harden, making the resistance of the slipper to retreat large, and even affecting the normal operation of the slipper after a long time. To clean these slag, the slag discharger needs to be disassembled, resulting in long-term shutdown of the slag discharger and affecting work efficiency.

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

[0031] The technical solution of this application will be further described below with reference to the drawings and through specific embodiments.

[0032] In some embodiments, as Figure 1 shown, this application provides a schematic vertical sectional structure diagram of an automatic slag discharging and anti-blocking device.

[0033] Figure 2 It shows a schematic front view structure of a slag hopper in the automatic slag discharging and anti-blocking device of the slag discharging machine of this application.

[0034] Please refer to Figure 1 and Figure 2 , an automatic slag discharging and anti-blocking device provided by this application is used for automatically discharging slag from the slag discharging machine. The automatic slag discharging and anti-blocking device of the slag discharging machine includes a slag cylinder 2, a telescopic mechanism 3, and a slag hopper 7. A feeding port 21 and a discharging port 22 are provided on the slag cylinder 2. The telescopic mechanism 3 is arranged inside the slag cylinder 2, and a sliding pillow 4 is connected to the telescopic end of the telescopic mechanism 3. The slag hopper 7 is arranged at the lower part of the slag cylinder 2. Among them, a discharging port 23 is also provided on the slag cylinder 2, and the discharging port 23 communicates the slag cylinder 2 and the slag hopper 7. One end of the sliding pillow 4 connected to the telescopic mechanism 3 is the first end, and the end of the sliding pillow 4 far from the telescopic mechanism 3 is the second end. The telescopic mechanism 3 drives the sliding pillow 4 to slide inside the slag cylinder 2, and the second end of the sliding pillow 4 slides past the discharging port 23. During the sliding process of the sliding pillow 4, the slag driven and lifted away from the discharging port 22 side can fall into the slag hopper 7 along the discharging port 23, avoiding the accumulation of slag on the sliding path of the sliding pillow 4, and avoiding the increased sliding resistance of the sliding pillow 4 caused by the accumulated slag and even affecting the normal operation of the sliding pillow 4. Through the setting of the slag hopper 7, the slag brought back by the sliding pillow 4 can be discharged from the slag cylinder 2 without the participation of personnel, saving manpower, eliminating the step of disassembling the slag discharging machine to clean the slag, greatly reducing the downtime of the slag discharging machine, and improving the working efficiency of the slag discharging machine.

[0035] In some embodiments, it further includes a bracket 1 and a limiting rod 6. The bracket 1 supports the slag cylinder 2. The upper part of the limiting rod 6 is rotatably connected to the bracket 1, and the lower part of the limiting rod 6 is rotatably connected to the first end of the sliding pillow 4.

[0036] In some embodiments, please refer to Figure 1 The bottom of the slag bucket 7 is an inclined bottom plate 71, which gradually decreases in the direction away from the slag barrel 2, that is, the side away from the slag barrel 2 is lower, so that the slag falling into the slag bucket 7 automatically moves to the side away from the slag barrel 2 under the action of gravity, making it convenient for maintenance personnel to clean the slag bucket 7.

[0037] In some embodiments, a movable door panel 8 is further provided on the side of the slag bucket 7, and the movable door panel 8 is slidably connected to the main body of the slag bucket 7. The slag bucket 7 can be conveniently opened and closed by the movable door panel 8 to quickly discharge the slag in the slag bucket 7.

[0038] In some embodiments, along the sliding direction of the movable door panel 8, a connecting rod 9 is connected to the upper part of the movable door panel 8. The connecting rod 9 can be connected to the telescopic oil cylinder to realize the electric switch of the movable door panel 8, further simplifying the cleaning of the slag bucket 7.

[0039] In some embodiments, Figure 3 A schematic diagram of the structure of the automatic slag discharge and anti-blocking device of the slag discharger of the present application is shown in a top view.

[0040] Please refer to Figure 1 and Figure 3 The second end of the ram 4 is provided with a push plate 5, and the lower part of the push plate 5 contacts the inner wall of the slag barrel 2. The push plate 5 increases the area of ​​the end of the slide plate and improves the efficiency of the slide plate in pushing the slag.

[0041] In some embodiments, two telescopic mechanisms 3 are provided, and each telescopic mechanism 3 corresponds to a ram 4. The two rams 4 push the push plate 5 at the same time, so that the thrust of the push plate 5 is greater, ensuring that the slag is pushed to the discharge port 22.

[0042] In some embodiments, the telescopic mechanism 3 is an oil cylinder, which has a large thrust and can achieve efficient energy conversion in a small space, and is suitable for heavy-load operations such as pushing slag.

[0043] The specific workflow of this application is as follows:

[0044] The slag enters the slag barrel 2 from the feed port 21, and then the telescopic mechanism 3 is started. The driving ram 4 of the telescopic mechanism 3 moves back and forth in the slag barrel 2. During the movement of the ram 4, the limit rod 6 limits the movement range of the ram 4. When the ram 4 moves back and forth to push the slag, part of the slag is squeezed and attached to the inner wall of the slag barrel 2, and then is planed by the ram 4 to the side away from the discharge port 22. As the telescopic assembly contracts, the slag planed by the ram 4 falls into the slag bucket 7 along the discharge port 23. The slag that falls into the slag bucket 7 slides along the inclined bottom plate 71 and slides to the position of the movable door plate 8. After a sufficient amount of slag is accumulated in the slag bucket 7, the cleaning and maintenance personnel lift the movable door plate 8 through the connecting rod 9 and open the slag bucket 7 for cleaning.

[0045] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope recorded in this specification.

[0046] The above-described embodiments merely represent several implementation manners of the present application, and are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application 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 do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application. For those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
