Description

Technical Field

[0001] This utility model relates to the field of sintering dust removal technology, specifically a fully automatic pre-silo feeding and optimized dust removal device. Background Technology

[0002] Currently, the optimal dust collection efficiency in dust collectors used in steel plant sintering processes depends on the required airflow. Among these parameters, dust collection capacity, pressure, and flow rate are crucial. A wider fluctuation range in the collected dust volume indicates a more stable process, even with varying airflow rates. Manually controlling the dust collection hood's valves during production and improving stable dust collection not only ensures adequate dust collection but also saves energy, improves reliable absorption, optimizes dust absorption capacity, reduces energy consumption and costs, and promotes long-term stable equipment operation.

[0003] During operation, strengthening the control and adjustment of each dust collector hood can enhance dust collection efficiency, save electricity and manpower. Dust absorption is also an important parameter affecting the smooth operation of the equipment. Practice shows that controlling and adjusting each dust collector hood helps improve dust absorption efficiency, reduce resource waste, decrease flow rate, increase absorption capacity, and simultaneously reduce electricity consumption and labor.

Detailed Implementation

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Please see Figures 1 to 5 As shown in the figure, this application embodiment provides a fully automatic pre-fed dust removal optimization device, including a frame 1 and several dust removal hoods 2 equidistantly installed at the bottom of the frame 1. Each of the several dust removal hoods 2 is provided with an air volume adjustment mechanism. The air volume adjustment mechanism includes a photoelectric distance measuring switch 3, a connecting pipe 4, a set of rotating shafts 5, a valve plate 6, a connecting rod 7, and an electric push rod 8. The photoelectric distance measuring switch 3 is installed on one side of the bottom of the dust removal hood 2. The connecting pipe 4 is sealed and inserted into the upper end of the dust removal hood 2. A set of rotating shafts 5 is movably inserted into both sides of the upper end of the connecting pipe 4. The valve plate 6 is installed between the set of rotating shafts 5. The connecting rod 7 is installed on the front rotating shaft 5. The bottom of the electric push rod 8 is hinged to the frame 1, and the telescopic end is hinged to the connecting rod 7.

[0022] In this embodiment, the device is applied in the pre-mixing room of sintered iron material in a steel plant. During the mixing process, the photoelectric distance measuring switch 3 detects that the material transport vehicle has arrived at the designated position. The photoelectric distance measuring switch 3 is triggered and controls the extension end of the electric push rod 8 to retract, which drives the valve plate 6 to open, and the dust collector hood 2 collects dust. When the photoelectric distance measuring switch 3 detects that the material transport vehicle has left the designated position, the extension end of the electric push rod 8 extends, which drives the valve plate 6 to close. The dust collector hood 2 is closed in time for silos that are not being fed temporarily. This reduces the amount of air used without affecting the dust removal effect. It can reduce the operating frequency of the dust removal fan, thereby reducing energy consumption. The valve plate 6 of the dust collector hood 2 is opened according to the specific feeding time of each silo, which reduces unnecessary dust removal air volume in time.

[0023] In some embodiments, a lifting mechanism is connected to the upper end of several dust hoods 2 respectively; the lifting mechanism includes a mounting plate 9, a rotary motor 10, a rotary shaft 11, two sets of winding wheels 12, two sets of steel wire connecting ropes 13, a set of rotating shafts 14 and two sets of guide wheels 15. The mounting plate 9 is mounted on the rear end of the frame 1, the rotary motor 10 is horizontally mounted on the mounting plate 9, the rotary shaft 11 is movably mounted on the front end of the mounting plate 9, the two sets of winding wheels 12 are mounted on the rotary shaft 11, the two sets of steel wire connecting ropes 13 are wound on the two sets of winding wheels 12 and their bottoms are respectively connected to the dust hoods 2, the set of rotating shafts 14 is movably mounted on the frame 1, the two sets of guide wheels 15 are alternately mounted on the set of rotating shafts 14, and the two sets of steel wire connecting ropes 13 are fitted on the two sets of guide wheels 15.

[0024] and in conjunction with the appendix Figure 4 and attached Figure 5 As shown, the upper end of the dust hood 2 is movably sealed and inserted into the connecting pipe 4. The rotating motor 10 rotates in both directions, and can drive the two sets of steel wire connecting ropes 13 on the two sets of winding wheels 12 through the rotating shaft 11 to pull the dust hood 2 up and down, so as to facilitate the adjustment of the height of the dust hood 2 and facilitate the use of dust collection. A set of rotating shaft 14 and two sets of guide wheels 15 can guide the two sets of steel wire connecting ropes 13. When the height of the dust hood 2 is adjusted, the preset value of the photoelectric distance measuring switch 3 needs to be adjusted synchronously.

[0025] In some embodiments, the rotating end of the rotary motor 10 is connected to the rotating shaft 11 by a set of transmission gears 16, which facilitates driving the rotating shaft 11 to rotate.

[0026] In some embodiments, the two sets of steel wire connecting ropes 13 are staggered to prevent interference.

[0027] In some embodiments, a sealing ring 17 is mounted on the valve plate 6 to improve the sealing effect.

[0028] In some embodiments, the connecting pipe 4 is connected to an external sintering dust collector to realize the dust collection function of the dust collection hood 2.

[0029] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
