Description

Technical Field

[0001] The utility model relates to the technical field of gas devices, in particular to a ventilation system optimization device in gas management. Background Art

[0002] Ventilation systems play a vital role in gas management, with their design and optimization directly impacting the safety and efficiency of mine operations. While traditional gas ventilation systems can reduce gas concentrations within mines to a certain extent, they still present some challenges in practical application.

[0003] First, traditional gas ventilation systems often lack effective filtration mechanisms. As a result, impurities such as dust and coal dust from within the mine are introduced into the ventilation system along with the wind. Long-term accumulation can clog the ventilation ducts, affecting ventilation efficiency and even posing safety risks. Furthermore, these impurities can cause wear and tear on the ventilation equipment, shortening its service life.

[0004] Secondly, traditional gas ventilation systems present difficulties in cleaning the filter assembly. Since the filter assembly is typically fixed within the ventilation duct, cleaning requires disassembling the entire duct, which is not only cumbersome, but also time-consuming and labor-intensive, increasing maintenance costs. Furthermore, if the filter assembly remains uncleaned for extended periods, its filtration effectiveness will be significantly reduced, impacting the performance of the entire ventilation system. Utility Model Content

[0005] The utility model aims to provide a ventilation system optimization device for gas management, so as to solve the problem that the existing gas ventilation device cannot collect filtered residues and cannot clean the filter components in time.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a ventilation system optimization device in gas control, including a ventilation duct, multiple filter screens are connected in the ventilation duct, the spacing between the multiple filter screens is the same, the side walls of the filter screens pass through the ventilation duct and are connected to a transmission assembly, the transmission assembly is used to drive the filter screen to reciprocate in the ventilation duct, the bottom end of the ventilation duct is connected to a collection tank, the collection tank is connected to the ventilation duct, and the collection tank is located at one end of the ventilation duct close to the transmission assembly.

[0007] The working principle of the utility model is as follows: after the gas ventilation operation is completed, the transmission assembly is started, and the transmission assembly drives multiple filter screens to move outside the ventilation duct. During the movement of the filter screens, the residue adhering to the filter screens will be screened on the inner wall of the ventilation duct. The residue will fall along the inner wall of the ventilation duct into the collection tank and be collected. After the filter screens are pulled out of the ventilation duct, the filter screens can be further cleaned using tools such as water guns.

[0008] The beneficial effects of the present invention are as follows: 1. The present invention adopts a push-pull filter screen, so that the filter screen can be pulled out in time after the gas ventilation operation is completed. This design makes it easy to collect the residue attached to the filter screen, and the pulled-out filter screen can be further cleaned, thereby ensuring that the filter screen can work stably for a long time. 2. The filter screen moves back and forth under the drive of the transmission assembly, screening the residue on the inner wall of the ventilation duct, and the residue then falls along the inner wall of the ventilation duct into the collection trough to be collected. This process has a high degree of automation, reduces manual intervention, and improves work efficiency. 3. Since the filter screen can be easily pulled out for cleaning, compared with the traditional method of disassembling the entire ventilation duct for cleaning, the present invention greatly simplifies the cleaning process and reduces maintenance costs. 4. By timely cleaning the filter screen and collecting residue, the wear of impurities on ventilation equipment and pipelines is reduced, thereby extending the service life of the equipment.

[0009] Furthermore, the transmission assembly includes a motor, a rotating rod, a transmission block, and multiple fixed rods. The multiple fixed rods are connected to one side of the filter screen. The multiple fixed rods between the multiple filter screens are connected by multiple connecting rods. The multiple fixed rods connected to one filter screen are connected to the transmission block. The middle of the transmission block is hollowed out, and a slider is connected to the hollowed-out portion of the transmission block. The slider is connected to the rotating rod, and the rotating rod is connected to the output shaft of the motor. The motor is fixedly installed at the work site. During operation, the motor is started, and the output shaft of the motor drives the rotating rod to rotate, causing the slider to move within the transmission block, synchronously driving the transmission block to move horizontally. At this time, the connecting rod drives the remaining fixed rods to move horizontally, and the filter screen follows the movement of the transmission block to move out of the ventilation duct.

[0010] Furthermore, the transmission block is tilted so that the transmission block can be better driven to move when the rotating block rotates.

[0011] Furthermore, multiple filter blocks are connected to one side of the ventilation duct, each with a through slot in the middle. The multiple filter blocks correspond one-to-one with the multiple filter screens. The filter blocks are located at the top of the collection tank, and one side of the filter screens passes through the through slot in the filter blocks. The filter blocks allow residue on the filter screens to pass through the filter blocks and into the collection tank, preventing the residue from being adsorbed on the inner wall of the ventilation duct.

[0012] Furthermore, the filter block is sloped, which allows the residue to enter the collection tank more quickly.

[0013] Furthermore, a concave block is provided at the center of the filter block, the concave block and the filter block have the same inclination angle, and the through groove is located at the center of the concave block. By setting the concave block, the residue can be limited in the filter block and move downward. BRIEF DESCRIPTION OF THE DRAWINGS
