Description

Technical Field

[0001] This invention relates to the field of sintering production technology, and in particular to a sintering ore bin with a filtration function. Background Technology

[0002] In the sintering process, in the storage, transportation and supply of raw materials, a certain number of silos are required for material transfer, transportation and storage.

[0003] The existing patent publication number "CN215324620U" discloses a sintered ore bin cleaning mechanism with a filtering function. It includes a base plate fixed to the end face of the head beam of a shuttle-type fabric conveyor belt, with multiple parallel extending slots on the base plate; multiple steel wire ropes, each correspondingly positioned within one of the slots; a constraint plate covering the surface of the steel wire ropes, clamping the steel wire ropes between the constraint plate and the base plate; and a fastening unit including bolts and nuts, which clamp the constraint plate and the base plate. When the shuttle-type fabric conveyor belt is feeding material, the steel wire ropes sweep across the grid at the bin opening, preventing material accumulation on the grid.

[0004] The above description has the following problems: During the storage of sintered materials in the sintering bin, although a cleaning device cleans the grid to remove large particles accumulated on the grid to the edge, it cannot promptly notify on-site personnel to remove the large particles accumulated on the grid. This results in a large amount of large particles covering the entire grid, affecting the normal operation of the sintering bin and posing a safety hazard. In addition, it cannot promptly notify on-site personnel whether the sintering bin is full of sintered materials, which can easily cause the sintered materials to overflow. Utility Model Content

[0005] The purpose of this invention is to provide a sintering ore trough with a filtration function, which solves the problem that existing sintering ore troughs cannot detect in a timely manner whether the grid is blocked or whether the sintering ore trough is full.

Each detection assembly includes a weighing sensor and a fixing member for fixing the weighing sensor to the hopper body. The lower end face of the grid is pressed against the detection part of the weighing sensor. A cleaning component is used to clean the material filtered out by the grid, and the cleaning component is disposed at the top of one side wall of the silo body; Alarm light; The control component includes the signal output terminal of the weighing sensor, the signal receiving terminal of the cleaning component, and the signal receiving terminal of the alarm light, all of which are connected to the signal terminal of the control component.

[0007] Furthermore, the support includes a base plate and a fixing plate vertically disposed on the upper edge of the base plate. The main body of the weighing sensor is fixed on the base plate, and the fixing plate is fixed to the inner wall of the silo body by bolts.

[0008] Furthermore, the cleaning assembly includes a cleaning shovel and a drive unit that drives the cleaning shovel to work. The drive unit is fixed to the hopper body by a support member.

[0009] Furthermore, the grid is evenly provided with a plurality of tension rings along its circumference, and the other end of each tension ring is disposed on the outer side wall of the hopper body.

[0010] Furthermore, a support plate is provided at the top of the detection part of the weighing sensor, and a limiting post inserted into the grid mesh is vertically provided on the upper end surface of the support plate.

[0011] Furthermore, the central region of the grille bulges upward, and the edges of the grille are lower than the central region of the grille.

[0012] 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 sintering ore bin with a filtration function, including a bin body and a grid installed at the top of the bin body. It also includes a weight detection component, a cleaning component, an alarm light, and a control component.

[0017] 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.

[0018] refer to Figure 1 , Figure 2 and Figure 3 The sintering ore bin provided in this embodiment includes a silo body 1 and a grid 2 disposed at the top of the silo body 1. When the sintering material is transported into this sintering ore bin, the sintering material falls into the central area of ​​the grid, and at this time, the grid 2 filters out the large particles of the sintering material.

[0019] refer to Figure 1 , Figure 2 and Figure 3It also includes a weight detection component 3, a cleaning component 4, a control component, and an alarm light mounted on the control component (the control component and alarm light are located far from this sintering ore bin in the monitoring room, so they are not shown in the diagram). Multiple weight detection components 3 are evenly distributed along the circumference of the silo body 1 inside the silo body 1. Each weight detection component 3 includes a load cell 31 and a fixing member 32 for fixing the load cell 31 to the silo body 1. The lower end face of the grid 2 presses against the detection part of the load cell 31. The load cell 31 is a GZL-YB-HT (dust) high-temperature resistant explosion-proof sensor. The fixing member 32 includes a base plate 321 and a fixing plate 322 vertically mounted on the upper edge of the base plate 321. The main body of the load cell 31 is fixed to the base plate 321, and the fixing plate 322 is fixed to the inner wall of the silo body 1 by bolts.

[0020] refer to Figure 1 , Figure 2 and Figure 3 The cleaning assembly 4 is used to clean the material filtered out by the grid 2. The cleaning assembly 4 is located at the top of one side wall of the hopper body 1. The cleaning assembly 4 includes a cleaning shovel 41 and a drive component 42 that drives the cleaning shovel 41. The drive component 42 is fixed to the hopper body 1 by a fixing component 32. The drive component 42 can be a drive motor that drives a ball screw or a drive cylinder. In this example, the drive component 42 is a drive cylinder.

[0021] refer to Figure 1 , Figure 2 and Figure 3 During operation, when a large number of large particles accumulate in the central area of ​​the grid 2, the drive component 42 activates the cleaning shovel 41, pushing the large particles in the central area of ​​the grid 2 to the edge of the grid 4. The central area of ​​the grid 2 bulges upwards, while the edge of the grid 2 is lower than the central area. This structural design allows the grid 2 to have a cleaning assistance function, enabling large particles filtered out to roll off to the edge of the grid during filtration, without affecting the filtration in the central area.

[0022] refer to Figure 1 , Figure 2 and Figure 3 The signal output terminal of the weighing sensor 31, the signal receiving terminal of the cleaning component 4, and the signal receiving terminal of the alarm light are all connected to the signal terminal of the control component. The control component includes a delay control unit and a data comparison unit.

[0023] refer to Figure 1 , Figure 2 and Figure 3The specific working principle is as follows: when the silo body 1 is working, the sintering material usually falls into the central area of ​​the grid 2. At this time, the grid 2 filters out large particles in the sintering material and collects them on the upper surface of the grid 2. The start and stop valve of the drive cylinder is controlled by the control component to open at regular intervals, thereby driving the cleaning shovel 41 to work through the drive cylinder, thus pushing the large particles on the grid 2 to the edge of the grid 2, ensuring that the middle area of ​​the grid 2 can work normally and not be blocked. During operation, when the silo body 1 is full of sintered material, some of the sintered material will accumulate on the grid 2. When the weighing detector detects that the weight of the grid 2 is greater than the set value, it will transmit a signal to the control component. At this time, the control component will control the alarm light to sound. After hearing the alarm light, the on-site personnel can check whether the silo body 1 is full of sintered material or the grid 2 is full of large particles. If the silo body 1 is full of sintered material, the sintered material conveying system will stop conveying sintered material into the silo body 1. If it is found that there are more large particles of material accumulated on the grid 2, the on-site personnel can use other tools (such as hooks) to clean out the large pieces of material from the edge of the grid 2.

[0024] refer to Figure 1 , Figure 2 and Figure 3 The grid 2 has multiple tension rings 8 evenly arranged along its circumference. The other end of each tension ring 8 is set on the outer wall of the hopper body 1. The tension rings 8 can eliminate the stress of material entering the grid 2 and avoid large displacement on both sides. The top of the detection part of the load cell 31 is provided with a support plate 9. The upper end surface of the support plate 9 is vertically provided with limiting posts 10 inserted into the grid of the grid 2. The support plate 9 and the limiting posts 10 provide support and limit, increasing the stability of the grid 2 pressed on the load cell 31.

[0025] In summary, the weight detection device can be used to detect whether the sintering material in the silo body 1 is full or whether there are too many large particles on the grid 2 that need to be cleaned in time. This provides production monitoring and operational capability, ensuring the continuous and normal operation of the sintering ore bin, and has a high degree of automation.
