Abstract
Description
Technical Field
[0001] This utility model belongs to the field of slag discharge technology for combustion furnaces, specifically relating to a slag-iron powder separation and slag discharge device for preventing clogging. Background Technology
[0002] By removing the slag remaining in the combustion furnace, the discharged slag iron powder may contain unreacted metals or useful components, which can be recycled and reused after processing, thereby improving resource utilization.
[0003] Currently, the common method for discharging slag is to manually insert a pry bar into the slag discharge pipe to clear it. Because the slag is hot and the impact force when it is discharged is large, operators often need to wear full protective gear. This method poses a significant safety hazard and makes it difficult to clean the slag adhering to it in a timely manner, which can easily cause blockage of the slag discharge pipe and affect subsequent cleaning. Utility Model Content
[0004] The purpose of this invention is to provide a slag-iron powder separation and slag discharge device that prevents clogging. It can be equipped with a swing structure inside the slag discharge pipe to discharge iron powder and slag adhering to the inner wall of the slag discharge pipe at regular intervals, thus preventing the iron powder and slag from clumping.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] A slag-iron powder separation and slag discharge device for preventing blockage includes a slag discharge pipe, an insulation pipe fixedly connected to the inner wall of the slag discharge pipe, a plurality of evenly distributed through grooves opened on the side wall of the insulation pipe, a movable plate movably connected in each through groove, and a plurality of telescopic components provided on the side wall of the slag discharge pipe, the telescopic components corresponding one-to-one with the movable plates.
[0007] Furthermore, the telescopic assembly includes a telescopic rod movably connected to the side wall of the slag discharge pipe. One end of the telescopic rod extends into the inner cavity of the slag discharge pipe and abuts against the movable plate. A baffle is fixedly connected to the side wall of the telescopic rod. A spring is sleeved on the side wall of the telescopic rod between the baffle and the slag discharge pipe. A transmission assembly is provided on the outside of the slag discharge pipe.
[0008] Furthermore, a ball bearing is rolled onto the other end face of the telescopic rod.
[0009] Furthermore, the transmission assembly includes multiple annular plates slidably connected to the side wall of the slag discharge pipe, multiple connecting rods fixedly connected between the multiple annular plates, and several triangular blocks fixedly connected to the top surface of each annular plate. Each triangular block corresponds to a telescopic rod, and the end of the telescopic rod away from the center of the slag discharge pipe abuts against the inclined surface of the triangular block. Two fixing plates are fixedly connected to the side wall of the slag discharge pipe, and two electric push rods are fixedly connected to the bottom surface of the upper fixing plate. The output end of the electric push rod is fixedly connected to the uppermost annular plate.
[0010] Furthermore, a corrugated pipe is fixedly connected between the two fixing plates.
[0011] Furthermore, each of the through grooves has a sealing groove on its bottom surface, and each of the movable plates has a protrusion that matches the sealing groove on its bottom surface.
[0012] Furthermore, a flow guide plate is fixedly connected to the inner wall of the heat insulation pipe on the upper side of the movable plate, and the flow guide plate is annular.
[0013] The technical effects achieved by this utility model are as follows:
[0014] This utility model discloses an anti-clogging slag iron powder separation and slag discharge device. Through the cooperation of slag discharge pipe, heat insulation pipe, movable plate and telescopic component, the device can periodically discharge iron powder and slag adhering to the inner wall of the slag discharge pipe by setting an oscillating structure inside the slag discharge pipe.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figures 1-7 As shown, a slag iron powder separation and slag discharge device for preventing blockage includes a slag discharge pipe 1, an insulation pipe 2 fixedly connected to the inner wall of the slag discharge pipe 1, a number of evenly distributed through grooves 3 opened on the side wall of the insulation pipe 2, and movable plates 4 movably connected in each through groove 3. A number of telescopic components are provided on the side wall of the slag discharge pipe 1, and the telescopic components correspond one-to-one with the movable plates 4.
[0026] like Figure 2 and Figure 7 As shown, the telescopic assembly includes a telescopic rod 7 movably connected to the side wall of the slag discharge pipe 1. One end of the telescopic rod 7 extends into the inner cavity of the slag discharge pipe 1 and abuts against the movable plate 4. A baffle 8 is fixedly connected to the side wall of the telescopic rod 7. A spring 9 is sleeved between the baffle 8 and the slag discharge pipe 1 on the side wall of the telescopic rod 7. A transmission assembly is provided on the outside of the slag discharge pipe 1.
[0027] The telescopic rod 7 is arc-shaped at the end near the movable plate 4, which facilitates its fit with the movable plate 4. The side wall of the movable plate 4 is rotatably connected to the side wall of the through groove 3 via a pin near the top surface. Thus, the movable plate 4 can be rotated along the central axis of the pin. Due to the restriction of the telescopic rod 7, the movable plate 4 can only unfold towards the center of the heat insulation pipe 2. Furthermore, during the extension and retraction process, the other end of the telescopic rod 7 is always in contact with the inclined surface of the triangular block 12 by the force of the spring 9, achieving the purpose of efficient transmission.
[0028] The other end face of the telescopic rod 7 is rolled with a ball bearing 10. The ball bearing 10 can reduce the friction between the telescopic rod 7 and the triangular block 12, avoid wear caused by hard friction and reduce transmission efficiency, thereby extending its service life.
[0029] like Figure 3 and Figure 4 As shown, the transmission assembly includes multiple annular plates 11 slidably connected to the side wall of the slag discharge pipe 1. Multiple connecting rods 13 are fixedly connected between the multiple annular plates 11. Several triangular blocks 12 are fixedly connected to the top surface of each annular plate 11. Each triangular block 12 corresponds to a telescopic rod 7. The end of the telescopic rod 7 away from the center of the slag discharge pipe 1 abuts against the inclined surface of the triangular block 12. Two fixed plates 14 are fixedly connected to the side wall of the slag discharge pipe 1. Two electric push rods 15 are fixedly connected to the bottom surface of the upper fixed plate 14. The output end of the electric push rod 15 is fixedly connected to the uppermost annular plate 11.
[0030] In the transmission assembly, the annular plate 11 can be slidably connected to the outer wall of the slag discharge pipe 1 in the form of a slider groove, or other limiting methods can be used; in addition, the electric push rod 15 is only one implementation method in this solution. In actual use, other components that can achieve reciprocating motion, such as cylinders and cams, can also be used for driving.
[0031] like Figure 1 and Figure 2 As shown, a corrugated pipe 16 is fixedly connected between the two fixed plates 14. The corrugated pipe 16 is preferably an aluminum foil pipe, such as the aluminum foil pipe used in range hood ducts, which has the advantages of high temperature resistance, extensibility, and corrosion resistance, and can provide good protection for the transmission components.
[0032] like Figure 6 As shown, the bottom surface of the through groove 3 is provided with a sealing groove 6, and the bottom surface of the movable plate 4 is provided with a protrusion that matches the sealing groove 6.
[0033] Specifically, the sealing groove 6 can also be set in other forms, for example, it can be opened into a U-shaped structure along the side of the through groove 3. When the movable plate 4 is closed, it can further achieve a sealing effect. In order to further discharge the shaken iron powder and slag to prevent residual blockage, the top of the heat insulation pipe 2 is fixedly connected to the slag discharge pipe 1, and the top of the heat insulation pipe 2 is not connected to the slag discharge pipe 1. If iron powder and slag seep out from the through groove 3, they can fall at the bottom of the heat insulation pipe 2, which is highly practical.
[0034] like Figure 2 and Figure 6 As shown, a guide plate 5 is fixedly connected to the inner wall of the heat insulation pipe 2 on the upper side of the movable plate 4. The guide plate 5 is annular. The guide plate 5 has multiple layers and is inclined downwards to facilitate the guidance of iron powder and slag towards the middle position of the heat insulation pipe 2.
[0035] The working principle of this utility model is as follows: First, the slag discharge pipe 1 is connected to the slag discharge position of the combustion furnace. After the combustion furnace has been used for a certain period of time, the inside of the slag discharge pipe 1 can be cleaned. The electric push rod 15 is started. The telescopic end of the electric push rod 15 drives the annular plate 11 to move upward. The annular plates 11 are connected by the connecting rod 13, so that the annular plates 11 can move upward as a whole. The annular plates 11 drive the triangular block 12 to move upward. The inclined surface of the triangular block 12 abuts against one end of the telescopic rod 7, so that the other end of the telescopic rod 7 pushes the movable plate 4 to unfold towards the center side of the slag discharge pipe 1, which is convenient for cleaning the iron powder and iron slag adhering to the inner wall of the heat insulation pipe 2.
[0036] In addition, by controlling the continuous extension and retraction of the electric push rod 15, the opening and closing speed of the movable plate 4 is accelerated, so that the movable plate 4 forms an amplitude, which makes it easier to shake off the iron powder and slag adhering to the surface of the movable plate 4, and prevent the iron powder and slag from adhering and accumulating, causing blockage and other phenomena.
[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
