Abstract

The present invention discloses a material clearing device for adhered material in a material yard, belonging to the technical field of bulk material processing. The device comprises a rope, a redirecting component, and a driving mechanism. The redirecting component is arranged on the inner wall surface of a single storage compartment partition wall in the material yard. The rope is arranged in a circuitous manner in the middle and lower part of the inner wall surface of the partition wall via the redirecting component, and the driving mechanism drives the rope to perform closed-loop bidirectional reciprocating motion. The present invention installs a rope-type material clearing device on the middle and lower part or bottom end of the partition wall surface inside the material compartment. When the material in the material compartment is taken by a reclaimer to near the bottom layer, the material clearing device of the present invention is activated. Relying on the reciprocating movement of the rope and the contact between the vibrator embedded in the rope and the material, the adhered material is shaken off to a range within the reach of the reclaimer on the bottom surface of the material compartment, thereby reducing material mixing and improving the stacking and reclaiming operation level of the raw material system.

Description

Technical Field

[0001] The present invention belongs to the technical field of bulk material processing, and relates to a production auxiliary device for a storage grid in a large raw material yard. The device can reduce material mixing during the stacking and retrieving operation of the raw material system, thereby improving and enhancing the operation level of the raw material system. Specifically, the device relates to a material yard adhesion cleaning device. Background Art

[0002] Large raw material yards, especially long closed raw material yards for storing iron ore and coking coal in the steel and metallurgical industry, are arranged with horizontal and vertical partition walls. The storage grids between the partition walls store different types of materials. The scraper reclaimer is used to reclaim the materials (see Figure 1 Due to the working characteristics of the scraper reclaimer equipment itself and the operational safety factors of the protective mechanical equipment, it is impossible to scrape all the materials in the material grid cleanly, resulting in a lot of dead materials adhering to the horizontal and vertical partition walls (see Figure 2 ). Once the material type is changed in production, it will cause a certain degree of mixing, affecting the composition and stability of the raw materials.

[0003] In particular, the process characteristics of the storage grids and the features of the reclaiming equipment lead to the presence of material adhering to the partition walls. This is particularly serious for high-moisture iron ore fines and coking coal. The stable composition of these materials is crucial for both the sintering and coking processes. Currently, due to the lack of specialized cleaning tools, most production processes involve manual cleaning of the storage grids, or simply covering the raw materials with new materials without any treatment, which affects the stability of the raw material composition. Summary of the Invention

[0004] In view of this, the object of the present invention is to provide a material yard adhesion material cleaning device with a simple structure, economy and practicality, which is used to solve the situation of manual operation or mixing of different types of materials.

[0005] The present invention is achieved through the following technical solutions:

[0006] The present invention provides a device for clearing adhered materials in a material yard, comprising a rope, a redirecting component and a driving mechanism. The redirecting component is arranged on the inner wall surface of a single material storage grid partition wall in the material yard. The rope is arranged in a circuitous manner in the lower middle part of the inner wall surface of the partition wall through the redirecting component, and the driving mechanism drives the rope to perform closed-loop bidirectional reciprocating motion.

[0007] By adopting the above scheme, the present invention installs a rope-type material cleaning device on the lower middle part or bottom end of the inner wall of the partition wall in the material grid, so as to shake the material to the range where the material reclaimer at the bottom of the material grid can take it, thereby reducing manual cleaning, reducing the mixing of different types of materials, improving the mixing impact of the stacking and reclaiming operation of the raw material system, and creating conditions for the production of fine materials for the main production process.

[0008] Furthermore, in order to improve the working efficiency of the rope, the redirecting component adopts a pulley or a cylindrical pin, which is provided in multiple numbers, so that a rope can be decomposed into several groups of ropes in the height direction and move simultaneously.

[0009] Furthermore, in order to make the rope clearer and more adhered, a plurality of vibrators are embedded on the rope at intervals.

[0010] Furthermore, in order to enable the rope to cut materials on both sides during the bidirectional movement, the vibrator is biconical and has different sizes and properties.

[0011] Furthermore, the driving mechanism includes a mounting frame and a driving unit and a transmission wheel arranged on the mounting frame. The mounting frame is fixed on the partition wall. The driving unit is used to drive the transmission wheel, and the transmission wheel is used for rope winding. The driving unit is driven by a reduction motor.

[0012] Furthermore, in order to increase the traction power of the rope and promote the improvement of the rope's material cleaning capacity, the driving mechanism also includes a surface-increasing redirecting wheel arranged on the mounting frame and located in front of the transmission wheel.

[0013] Furthermore, in order to achieve the tensioning capability of the rope, the position of the surface-increasing redirecting wheel relative to the transmission wheel on the mounting frame is adjustable, and the rope can be wound around it in single or multiple strands.

[0014] Furthermore, in order to ensure that the rope has sufficient tension and does not slip during operation, the cleaning device also includes a tensioning mechanism acting on the rope, and the tensioning mechanism includes a tensioning wheel for winding the rope and a screw for retracting and releasing the tensioning wheel.

[0015] The advantages of the present invention are:

[0016] 1. The present invention installs a rope-type material clearing device at the lower middle part or bottom end of the partition wall in the material grid. When the material in the material grid is taken close to the bottom layer, the material clearing device of the present invention is activated. Relying on the reciprocating movement of the rope and the contact between the vibrator embedded in the rope and the material, the adhering material is shaken off to the range where the reclaimer at the bottom of the material grid can take it, thereby reducing material mixing and improving the stacking and reclaiming operation level of the raw material system.

[0017] 2. This invention combines redirecting components with ropes to form a rope-type reciprocating mechanism. By redirecting a single rope into multiple strands, it can achieve circuitous coverage of the middle and lower portion of the partition wall. This allows for rapid reciprocating movement over short distances, effectively removing adhering materials. Furthermore, the number of redirecting components, their installation direction, and their location can be flexibly adjusted based on the partition wall shape and operational requirements.

The objects and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following describes the embodiments of the present invention by means of specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and the following embodiments and features in the embodiments can be combined with each other without conflict.

[0028] like Figure 3-6As shown, the present invention provides a material yard adhesion material cleaning device, comprising a rope 1, a redirecting component 2, and a driving mechanism 3. The redirecting component 2 is arranged on the inner wall surface of a single storage compartment partition wall in the material yard, and the single storage compartment partition wall in the material yard includes a longitudinal partition wall and two transverse partition walls perpendicular to the longitudinal partition wall. The rope 1 is arranged in a circuitous manner on the middle and lower part of the inner wall surface of the partition wall through the redirecting component 2, that is, the rope is arranged in a circuitous manner on the longitudinal partition wall and the two transverse partition walls in the horizontal and vertical directions through the redirecting component, and the driving mechanism 3 drives the rope 1 to perform closed-loop bidirectional reciprocating motion. With the above scheme, by installing a rope-type material cleaning device on the middle and lower part or bottom end of the inner wall surface of the material compartment inner partition wall, the material is shaken off to a range that can be retrieved by the material reclaimer at the bottom of the material compartment, thereby reducing manual cleaning, reducing the mixing of different types of materials, improving the mixing effect of the stacking and reclaiming operation of the raw material system, and creating conditions for the production of fine materials for the main production process.

[0029] The redirecting component 2 in this embodiment utilizes multiple pulleys to decompose a single rope into several groups of ropes in the vertical direction, each of which operates simultaneously. This combination of the redirecting component and the rope forms a rope-type reciprocating mechanism. By redirecting a single rope into multiple ropes, a circuitous covering of the middle and lower portions of the partition wall can be achieved, enabling the rope to move back and forth quickly over a short distance, effectively cleaning adhered materials. Furthermore, the number of groups, installation direction, and position of the redirecting component can be flexibly set based on the partition wall shape and operational requirements. Of course, in different embodiments, the redirecting component can also utilize other similar components, such as cylindrical pins. As long as they can achieve rope redirection and pulling, they can be considered to be consistent with the present invention.

[0030] In this embodiment, a number of biconical vibrators 4 are intermittently embedded in the rope 1. These biconical structures can be biconical or bipyramidal, and come in a variety of sizes and shapes. These vibrators not only cut material from both sides but also generate a certain vibration in the rope as it rapidly reciprocates. Through the cutting and vibration of the vibrators and the material, adhering material and accumulated dead material are shaken off to the bottom of the grating.

[0031] The drive mechanism 3 in this embodiment includes a mounting frame 31, a drive unit 32, a transmission wheel 33, and a surface-adding and redirecting wheel 34 mounted on the mounting frame 31. The mounting frame 31 is fixed to a partition wall or the ground. The drive unit 32 is used to drive the transmission wheel 33, which is used to wind the rope 1. The drive unit 32 is driven by a reduction motor. The surface-adding and redirecting wheel 34 is mounted on the mounting frame 31 and located in front of the transmission wheel 33. It serves to redirect the rope in advance and increase the traction force on the rope. In addition, the surface-adding and redirecting wheel 34 can be adjusted relative to the transmission wheel 33 on the mounting frame 31. This allows the distance between the surface-adding and redirecting wheel and the transmission wheel to be adjusted, thereby adjusting the drive wrap angle. The rope can be wound around the surface-adding and redirecting wheel in a single strand or in multiple strands.

[0032] The material cleaning device in another embodiment also includes a tensioning mechanism 5 acting on the rope 1. The tensioning mechanism 5 includes a tensioning wheel 51 for winding the rope 1 and a screw rod 52 for retracting and releasing the tensioning wheel 51. In this way, a tensioning mechanism is provided at one end of the rope so that the rope has sufficient tension to ensure that it does not slip during operation.

[0033] In this embodiment, the material yard has numerous retaining wall sections, and the material removal device can be installed in each section. The installation height and position of the rope mechanism can be flexibly adjusted based on the different types of materials stored in different sections. The ropes can be divided into several groups to accommodate both vertical and sloped retaining wall shapes. Furthermore, the number of groups, installation direction, and position of the redirecting components can be flexibly adjusted based on the partition wall shape and operational requirements.

[0034] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It is apparent that various modifications and variations may be made by those skilled in the art without departing from the spirit and scope of the present invention. Thus, the present invention is intended to encompass such modifications and variations as long as they fall within the scope of the claims and their equivalents.
