Description

Technical Field

[0001] This utility model relates to the field of slag cleaning technology, and in particular to a slag cleaner for a slag removal system with a fire-resistant slag cleaning mechanism. Background Technology

[0002] Maintaining the cleanliness of the ore chain (connectors) and effectively reducing slag adhesion is crucial for the stable operation of the slag removal system. It ensures smooth and stable conveying, reduces equipment wear and mechanical failure rates, extends the service life of core components, and prevents unplanned downtime due to serious malfunctions such as sprocket jamming. Furthermore, keeping the ore chain clean reduces the frequency of manual slag removal, lowers maintenance costs and safety risks, and enhances continuous operation capabilities.

[0003] In existing technologies, when slag is discharged to the slag removal system, it tends to fall onto the links or connecting parts of the ore chain (connector) and be carried to the tail end of the machine as the ore chain moves. This causes the slag to accumulate continuously between the sprocket and the track, which can easily lead to sprocket jamming, transmission system overload, and in severe cases, equipment shutdown. Manual slag removal is required, which is not only inefficient but also poses a significant safety risk, seriously affecting production continuity and operational safety. Utility Model Content

[0004] The purpose of this utility model is to provide a slag cleaner for a slag removal system of a fire-resistant slag removal mechanism, so as to solve the problem mentioned in the background art that slag easily falls on the chain links or connecting parts of the ore chain (connector) and causes the sprocket to jam.

[0010] Based on the preferred embodiment of this technical solution, the mounting frame includes two plates welded to the slag discharge pipe. An L-shaped plate is provided on the side of the plate away from the slag discharge pipe. A flame-retardant belt is attached to the L-shaped plate, and a dovetail wire is threaded through the side of the flame-retardant belt away from the L-shaped plate and connected to the L-shaped plate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides an embodiment of a slag removal system for a fire-resistant slag sweeping mechanism. The slag sweeper includes a bearing component installed within a channel 10 in a cement floor 1. The bearing component includes a bearing plate 2 and connectors linking adjacent bearing plates 2. A slag discharge pipe 4 spans the channel 10 on the cement floor 1, through which slag can fall. A cleaning component 3 is installed on one side of the slag discharge pipe 4. The cleaning component 3 includes a mounting frame and a flame-retardant belt 31 mounted on the mounting frame. The flame-retardant belt 31 is used for cleaning the connectors. By installing the bearing component within the channel 10 and cooperating with the cleaning component 3, a compact and efficient slag removal system is formed. The flame-retardant belt 31 acts on the connector area, removing slag accumulated at the connection points and preventing jamming of the connection structure due to slag, significantly improving the system's operational reliability and safety. Simultaneously, the flame-retardant material ensures the belt's long-term stable operation in high-temperature environments, extending its service life in the face of friction-generated heat.

[0019] Please see Figure 1-5 A further solution based on this embodiment is as follows: several load-bearing components are connected end to end. Each load-bearing component also includes a connecting plate 21 at one end of the load-bearing plate 2 and two clamping plates 22 at the other end of the load-bearing plate 2. The two clamping plates 22 of one load-bearing plate 2 can clamp the connecting plate 21 of another load-bearing plate 2. The overlapping connection structure of "clamping plate 22 + connecting plate 21" allows multiple load-bearing plates 2 to be continuously spliced ​​and installed, and also provides a basic condition for subsequent fixation using the insertion rod 23, thereby enhancing the structural stability and maintainability of the overall load-bearing component.

[0020] Please see Figure 1-4 A further embodiment of this solution involves a rod 23 passing through both the clamping plate 22 and the connecting plate 21. One end of the rod 23 has an integrally formed fixing head, and a retaining ring can be installed on the rod 23. Through the cooperation of the rod 23 and the retaining ring, quick locking and releasing between the bearing plates 2 can be achieved without bolt tightening, making operation simple and the connection secure. The integrally formed fixing head and the retaining ring form end-to-end limiting, preventing the rod 23 from falling off under vibration and ensuring connection reliability. This design facilitates quick disassembly of a single bearing plate 2 during routine maintenance, improving maintenance efficiency.

[0021] Please see Figure 1-4A further embodiment of this solution involves an integrally formed reinforcing plate 221 on the clamping plate 22, which is welded to the bearing plate 2. The reinforcing plate 221 significantly improves the structural strength and deformation resistance of the clamping plate 22, especially under large lateral forces, effectively preventing cracking or loosening. The integral forming combined with welding ensures the rigidity and durability of the connection points, extends the overall service life of the bearing components, and adapts to harsh working conditions such as high temperatures and heavy loads.

[0022] Please see Figure 1-4 A further solution based on this embodiment is as follows: A bearing cavity 20 is provided on the bearing plate 2, allowing the slag from the slag discharge pipe 4 to fall into the bearing cavity 20. The slag discharge pipe 4 is provided with connecting feet 41, which are connected to the cement floor 1 via expansion bolts. The bearing cavity 20 is designed to centrally receive the slag falling from the slag discharge pipe 4, relatively reducing its scattering into other areas of the channel 10. The slag discharge pipe 4 is firmly fixed to the cement floor 1 via the connecting feet 41 and expansion bolts, ensuring stable installation and maximizing the amount of slag that falls into the bearing cavity 20.

[0023] Please see Figure 2-5 A further embodiment of this solution is as follows: The mounting frame includes two plates 32 welded to the slag discharge pipe 4. An L-shaped plate 33 is provided on the side of the plate 32 away from the slag discharge pipe 4. A flame-retardant belt 31 is attached to the L-shaped plate 33, and a dovetail wire 311 is threaded through the side of the flame-retardant belt 31 away from the L-shaped plate 33 to connect it to the L-shaped plate 33. The mounting frame is directly welded to the slag discharge pipe 4 via the plates 32, resulting in a compact structure and secure installation without the need for an additional support foundation. The L-shaped plate 33 provides a stable support surface for the flame-retardant belt 31, and the dovetail wire 311 reliably fixes the belt edge, preventing it from falling off during operation.

[0024] Please see Figure 2-5 A further solution based on this embodiment is as follows: a connecting pipe 34 is welded between the two L-shaped plates 33, and the connecting pipe 34 is used to reinforce the mounting frame. Welding the connecting pipe 34 between the two L-shaped plates 33 can effectively enhance the overall structural rigidity of the mounting frame and prevent the L-shaped plates 33 from deforming due to uneven stress. This design improves the stability of the cleaning component 3, ensures that the flame-retardant belt 31 remains flat and taut during operation, avoids belt deviation or wear due to frame twisting, and thus ensures continuous and effective cleaning of the connecting area.

[0025] Please see Figure 2-5A further embodiment of this solution is as follows: a fixing seat 35 is installed in the channel 10 using expansion screws. A return spring 36 is provided on the side of the fixing seat 35 facing the flame-retardant belt 31. The end of the return spring 36 away from the fixing seat 35 hooks onto the flame-retardant belt 31. Through the cooperation of the fixing seat 35 and the return spring 36, the flame-retardant belt 31 is prevented from bending and warping due to long-term use. The return spring 36 can pull the flame-retardant belt 31 back to the correct position, ensuring efficient cleaning of the connectors.

[0026] Working Principle: After being discharged from the slag discharge pipe 4, the slag falls into the bearing cavity 20 of the bearing plate 2, and may accumulate in the connecting area between adjacent bearing plates 2. The bearing assembly moves as a whole along the channel 10 under external power, such as a traction chain or other existing technology. During this process, the flame-retardant belt 31 of the cleaning assembly 3 hangs down naturally under its own weight, with its bottom surface in contact or close to the upper surface of the connecting piece. As the bearing assembly moves horizontally, the connecting piece and the flame-retardant belt 31 slide relative to each other, causing the belt to scrape off the slag adhering to the connecting piece like a "scraper," thus achieving automatic cleaning. The return spring 36 applies tension to the flame-retardant belt 31, ensuring that it can quickly return to its original position when subjected to slag resistance, adhering to the connecting area, preventing the belt from being lifted and unable to return to its original position, and also preventing the flame-retardant belt 31 from curling up due to long-term use, ensuring continuous and effective cleaning. Since the movement of the bearing component within the channel 10 adopts existing technology, this utility model focuses on the cooperation structure between the cleaning component 3 and the bearing component, realizing a passive automatic slag cleaning function that is simple in structure, easy to maintain, and resistant to high temperature, effectively avoiding the problem of slag jamming at the connection point.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
