Description

Technical Field

[0001] This application relates to the technical field of slag discharge machines, and in particular to an automatic slag discharge and anti-blocking device and a 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 pushed by the grate to the slag pit, and then pulled out of the furnace by the slag remover to clear the slag buildup.

[0003] After the slag enters the slag discharger's slag cylinder, it is pushed out of the discharge port by the ram within the machine. To ensure the ram cleans the slag inside the slag cylinder thoroughly, its end needs to be flush against the inner wall of the cylinder. After prolonged operation, slag will adhere to the inner wall of the slag cylinder. As the ram slides back and forth along this wall, it inevitably pushes some slag away from the discharge port. This slag, accumulating and hardening, increases the ram's resistance to retraction, and over time, may even affect its normal operation. Cleaning this slag requires disassembling the slag discharger, causing prolonged downtime and impacting efficiency.

[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 application is to provide an automatic slag discharge and anti-clogging device for a slag discharge machine, so as to quickly clean up the slag accumulated in the slag discharge machine on the side away from the discharge port.

[0006] An automatic slag discharge and anti-clogging device is used for automatic slag discharge from a slag discharge machine, comprising a slag cylinder, a telescopic mechanism, and a slag hopper; the slag cylinder has an inlet and an outlet; the telescopic mechanism is disposed inside the slag cylinder, and the telescopic end of the telescopic mechanism is connected to a sliding ram; the slag hopper is disposed at the lower part of the slag cylinder.

[0007] The slag cylinder is provided with a discharge port, which connects the slag cylinder and the slag hopper; the end of the slide block connected to the telescopic mechanism is the first end, and the end of the slide block away from the telescopic mechanism is the second end; the telescopic mechanism drives the slide block to slide inside the slag cylinder, and the second end of the slide block slides past the discharge port.

[0008] Furthermore, the bottom of the slag hopper is an inclined bottom plate, which gradually decreases in the direction away from the slag cylinder.

[0009] Furthermore, the side of the slag hopper is also provided with a movable door panel, which is slidably connected to the main body of the slag hopper.

[0010] Furthermore, a connecting rod is connected above the movable door panel along the sliding direction of the movable door panel.

[0011] Furthermore, a pusher plate is provided at the second end of the slide block, and the lower part of the pusher plate contacts the inner wall of the slag cylinder.

[0012] Furthermore, it also includes a support frame that supports the slag cylinder.

[0013] Furthermore, it includes a limiting rod, the upper part of which is rotatably connected to the bracket, and the lower part of which is rotatably connected to the first end of the slide block.

[0014] Furthermore, there are two telescopic mechanisms, each corresponding to one slide block.

[0015] Furthermore, the telescopic mechanism is a hydraulic cylinder.

[0016] In addition, this application also provides a slag discharge machine, including the automatic slag discharge and anti-clogging device described above.

[0017] Compared with the prior art, this application has the following beneficial effects:

[0018] (1) The automatic slag discharge and anti-clogging device of the slag discharge machine in this application is equipped with a slag hopper and a discharge port on the slag cylinder, which connects the slag cylinder and the slag hopper. During the sliding process of the slide ram, the slag that is lifted and driven away from the discharge port can fall into the slag hopper along the discharge port, avoiding the accumulation of slag on the sliding path of the slide ram and preventing the accumulated slag from increasing the sliding resistance of the slide ram or even affecting the normal operation of the slide ram. With the setting of the slag hopper, the slag brought back by the slide ram can be discharged from the slag cylinder without the need for personnel intervention, saving manpower and eliminating the step of disassembling the slag discharge machine to clean the slag, greatly reducing the downtime of the slag discharge machine and improving the working efficiency of the slag discharge machine.

[0019] (2) Furthermore, the bottom plate of the slag hopper is an inclined bottom plate, which makes the slag falling into the slag hopper automatically move away from the slag cylinder under the action of gravity, making it easier for maintenance personnel to clean the slag hopper.

[0020] (3) Furthermore, the side of the slag hopper is provided with a movable door panel, which can be used to easily open and close the slag hopper to quickly discharge the slag in the slag hopper. Attached Figure Description

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

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

[0032] In some embodiments, such as Figure 1 As shown in the figure, this application provides a vertical cross-sectional structural diagram of an automatic slag discharge and anti-clogging device.

[0033] Figure 2 The diagram shows the main view of the slag hopper in the automatic slag discharge and anti-clogging device of the slag discharge machine of this application.

[0034] Please refer to Figure 1 and Figure 2 This application provides an automatic slag discharge and anti-clogging device for automatically discharging slag from a slag discharger. The automatic slag discharge and anti-clogging device for the slag discharger includes a slag cylinder 2, a telescopic mechanism 3, and a slag hopper 7. The slag cylinder 2 has an inlet 21 and an outlet 22. The telescopic mechanism 3 is located inside the slag cylinder 2, and its telescopic end is connected to a sliding ram 4. The slag hopper 7 is located at the lower part of the slag cylinder 2. The slag cylinder 2 also has a discharge port 23, which connects the slag cylinder 2 and the slag hopper 7. The end of the sliding ram 4 connected to the telescopic mechanism 3 is the first end, and the end of the sliding ram 4 away from the telescopic mechanism 3 is the second end. The telescopic mechanism 3 drives the sliding ram 4 to slide inside the slag cylinder 2, and the second end of the sliding ram 4 slides past the discharge port 23. During the sliding process of the slide block 4, the scrap material carried away from the discharge port 22 can fall into the slag hopper 7 along the discharge port 23, preventing the scrap material from accumulating on the sliding path of the slide block 4. This avoids the accumulated scrap material increasing the sliding resistance of the slide block 4 and even affecting its normal operation. With the slag hopper 7, the scrap material brought back by the slide block 4 can be discharged from the slag cylinder 2 without human intervention, saving manpower and eliminating the need to disassemble the slag discharge machine to clean the scrap material. This greatly reduces the downtime of the slag discharge machine and improves its working efficiency.

[0035] In some embodiments, the device further includes a bracket 1 and a limiting rod 6, with the bracket 1 supporting 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 slide block 4.

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

[0037] In some embodiments, a movable door plate 8 is also provided on the side of the slag hopper 7, and the movable door plate 8 is slidably connected to the main body of the slag hopper 7. The slag hopper 7 can be easily opened and closed through the movable door plate 8 to quickly discharge the slag in the slag hopper 7.

[0038] In some embodiments, a connecting rod 9 is connected above the movable door plate 8 along the sliding direction of the movable door plate 8. The connecting rod 9 can be connected to a telescopic hydraulic cylinder to realize the electric opening and closing of the movable door plate 8, further simplifying the cleaning of the slag hopper 7.

[0039] In some embodiments, Figure 3 A top view schematic diagram of the automatic slag discharge and anti-clogging device of the slag discharge machine of this application is shown.

[0040] Please refer to Figure 1 and Figure 3 A pusher plate 5 is provided at the second end of the slide block 4, and the lower part of the pusher plate 5 contacts the inner wall of the slag cylinder 2. The pusher plate 5 increases the area of ​​the end of the slide block and improves the efficiency of the slide block in pushing the slag.

[0041] In some embodiments, two telescopic mechanisms 3 are provided, each corresponding to one slide block 4. The two slide blocks 4 simultaneously push the push plate 5, increasing the pushing force of the push plate 5 and ensuring that the slag is pushed to the discharge port 22.

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

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

[0044] The slag enters the slag cylinder 2 through the inlet 21. Then, the telescopic mechanism 3 is activated, and the drive slide 4 of the telescopic mechanism 3 moves back and forth inside the slag cylinder 2. During the movement of the slide 4, the limiting rod 6 restricts the range of movement of the slide 4. When the slide 4 moves back and forth, pushing the slag, some of the slag is squeezed and adhered to the inner wall of the slag cylinder 2, and then scooped away from the outlet 22 by the slide 4. As the telescopic assembly retracts, the slag scooped up by the slide 4 falls into the slag hopper 7 along the discharge port 23. The slag falling into the slag hopper 7 slides along the inclined bottom plate 71 to the position of the movable door plate 8. After a sufficient amount of slag has accumulated in the slag hopper 7, the cleaning and maintenance personnel lift the movable door plate 8 through the connecting rod 9 to open the slag hopper 7 for cleaning.

[0045] 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.

[0046] The above-described embodiments are merely illustrative of several implementation methods of this application and are only used to illustrate the technical solutions of this application, not to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application. For those skilled in the art, several variations and improvements can be made without departing from the concept of this application, and these all fall within the protection scope of this application.
