Description

Technical Field

[0001] This utility model is applied in the field of sintering technology, and in particular relates to a bulk material unloading device for a sintering machine. Background Technology

[0002] During the transportation of sintering machine trolleys along the sintering track, material spillage usually occurs. In production, the scattered sintering materials are collected and transported to the designated disposal area via conveyor belts for recycling.

[0003] The height difference between the conveyor belt and the sintering trolley is significant, typically around 18 meters. To facilitate the transport of scattered sintered material onto the conveyor belt, a vertically installed discharge pipe is used. A control valve at the bottom of the discharge pipe controls its opening and closing. Due to the large height difference, the sintered material easily impacts the valve plate of the control valve as it falls from the discharge pipe onto the conveyor belt, causing deformation and damage. Furthermore, when the control valve is open, the sintered material falls directly vertically onto the conveyor belt, resulting in a large impact force that can also damage the conveyor belt, affecting normal operation.

[0004] Therefore, the purpose of this utility model is to provide a material unloading device that can extend its service life. Utility Model Content

[0005] The purpose of this utility model is to provide a bulk material unloading device for sintering machines, which solves the problems of existing unloading components being easily damaged by impact, worn, and having a short service life.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a bulk material unloading device for a sintering machine, including a unloading pipe. A buffer assembly is detachably installed at the bottom of the unloading pipe. The buffer assembly includes a buffer box, a valve plate disposed in the buffer box, and a lifting component that drives the valve plate to move vertically. The valve plate divides the interior of the buffer box into a buffer space and a discharge space. The top of the valve plate extends upward out of the buffer box and connects to the lifting component. The upper end face of the buffer space is provided with an inlet communicating with the unloading pipe, and the lower end face of the discharge space is provided with a discharge port for discharging sintered materials.

[0007] Furthermore, both sides of the buffer box in the width direction are provided with guide plates for guiding the valve plate.

[0008] Furthermore, the inner bottom wall of the buffer space is inclined downwards towards the material drop space.

[0009] Furthermore, an observation window is provided between the upper surface of the material dropping space and the side away from the buffer space, and a sealing plate is provided on the top cover of the observation window.

[0010] Furthermore, the lifting component is one of a lifting cylinder, a hydraulic push rod, or a worm gear lift, and the longitudinal extension end of the lifting component is connected to the top of the valve plate.

[0011] Furthermore, a buffer pipe is detachably provided between the feed inlet of the buffer space and the bottom end of the discharge flow pipe. Multiple buffer plates are arranged sequentially from top to bottom along the axial direction inside the buffer pipe. The multiple buffer plates are staggered on the opposite inner walls of the buffer pipe, and the end of the buffer plate away from the side wall of the buffer pipe is inclined downward.

[0012] Furthermore, a reinforcing rib is provided between the lower end face of the buffer plate and the inner wall of the buffer pipe.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides a bulk material unloading device for a sintering machine. By setting this buffer component at the bottom of the unloading pipe, the scattered sintering material falls into the buffer space through the unloading pipe. At this time, a certain amount of sintering material accumulates at the bottom of the buffer space. When the sintering material continues to fall, "material throttling" is performed to play a buffering role and prevent the material from directly impacting the bottom wall of the buffer space. The valve plate in the buffer assembly is located between the buffer space and the material discharge space. When the sintered material is discharged from the discharge pipe into the buffer box, it will not directly hit the valve plate. Therefore, the valve plate in the structure will not experience wear and deformation, thus extending its service life. The buffer components are designed to buffer the sintered material discharged from the discharge pipe onto the conveyor belt, preventing the sintered material from being directly discharged onto the conveyor belt and causing impact damage. This protects the conveyor belt and extends its service life. Attached Figure Description

[0016] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Example 1 refer to Figure 1 , Figure 2 and Figure 3The sintering machine bulk material unloading device provided in this example includes a material unloading pipe 1. A buffer assembly 2 is detachably installed at the bottom of the material unloading pipe 1. The buffer assembly 2 includes a buffer box 21, a valve plate 22 installed in the buffer box 21, and a lifting component 23 that drives the valve plate 22 to move vertically. The valve plate 22 divides the interior of the buffer box 21 into a buffer space 211 and a material dropping space 212. The top of the valve plate 22 extends upward out of the buffer box 21 and is connected to the lifting component 23. The upper end face of the buffer space 211 is provided with a feed inlet 3 that communicates with the material unloading pipe 1, and the lower end face of the material dropping space 212 is provided with a discharge port 4 for discharging sintered materials. By setting this buffer component 2 at the bottom of the discharge pipe 1, the scattered sintered material falls into the buffer space 211 through the discharge pipe 1. At this time, a certain amount of sintered material accumulates at the bottom of the buffer space 211. When the sintered material continues to fall, "material feeding" is performed to buffer the material and prevent it from directly impacting the bottom wall of the buffer space 211. When the valve plate 22 is opened, the sintered material in the buffer space 211 enters the discharge space 212 and falls onto the conveyor belt 5 through the discharge port 4 at the bottom of the discharge space 212. The conveyor belt 5 then transports the sintered material to the place to be placed.

[0020] refer to Figure 1 , Figure 2 and Figure 3 In the buffer assembly 2, the valve plate 22 is located between the buffer space 211 and the material discharge space 212. When the sintering material is discharged from the discharge pipe 1 into the buffer box 21, it will not directly impact the valve plate 22. Therefore, the valve plate 22 in the structure will not experience wear and deformation, thus extending its service life.

[0021] The buffer component 2 provides a certain buffering effect on the sintered material discharged from the discharge pipe 1 onto the conveyor belt 5, preventing the sintered material from being directly discharged onto the conveyor belt 5 and causing impact damage, thus protecting the conveyor belt 5 and extending its service life.

[0022] refer to Figure 1 , Figure 2 and Figure 3 The lifting component 23 is one of a lifting cylinder, a hydraulic push rod, or a worm gear jack. The longitudinal extension end of the lifting component 23 is connected to the top of the valve plate. In this example, a worm gear jack is used. The worm gear jack is installed on the outer wall of the discharge pipe 1. The bottom of the lifting end of the worm gear jack is fixed to the upper end of the valve plate 22. The position of the lifting component on the discharge pipe is only for illustration and can be adjusted according to the actual working conditions. By manually operating the worm gear jack, the valve plate 22 is driven to move longitudinally up and down, thereby adjusting the discharge flow rate of the sintered material from the buffer space to the discharge space.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The buffer box 21 has guide plates 6 on both sides of its width direction for guiding the valve plate 22. One side of the valve plate 22 is attached to one side of the guide plate 6. When the valve plate 22 moves longitudinally, the guide plate 6 plays a guiding role to ensure the stability of the longitudinal movement of the valve plate 22. The guide plate 6 is located on the left side of the valve plate 22 in the horizontal direction, so it is not easy for material to accumulate.

[0024] refer to Figure 1 , Figure 2 and Figure 3 The bottom wall of the buffer space 211 is inclined downwards towards the material discharge space, which facilitates unloading. An observation window is provided between the upper end of the material discharge space 212 and the side away from the buffer space 211. The observation window is covered by a sealing plate 7, which allows for easy viewing of the inside of the buffer box 21. When there is accumulated material in the buffer space 211 that is difficult to discharge, the sealing plate 7 can be opened and the material can be cleaned through the observation window. The operation is simple and convenient.

[0025] Example 2 The content and structure of this example are basically the same as those of Example 1, except that: refer to Figure 4 A buffer pipe 8 is detachably installed between the feed inlet of the buffer space 211 and the bottom end of the discharge pipe 1. Multiple buffer plates 9 are arranged sequentially from top to bottom along the axial direction inside the buffer pipe 8, staggered on opposite inner walls of the buffer pipe 8. The end of each buffer plate 9 away from the side wall of the buffer pipe 8 is inclined downwards. A reinforcing rib 10 is provided between the lower end face of the buffer plate 9 and the inner wall of the buffer pipe 8. The buffer pipe 8 pre-buffers the sintering material entering the buffer assembly 2, reducing the speed at which the sintering material falls into the buffer space 211, thus protecting the buffer box 21. Of course, this structure can be selectively installed when the buffer assembly 2 can effectively buffer the falling sintering material.

[0026] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
