Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a porous coupling plate for uniform airflow and direction adjustment in air jets, such as for a parallel blowing and suction type air curtain dust separation system. Background Technology
[0002] The hoisting passageway in a metal mine crushing workshop is primarily used for hoisting large equipment and heavy objects into and out of the workshop. It is typically located next to the unloading point and is usually open at ground level, leading directly into the underground workshop. Due to the practical needs of equipment movement and workshop ventilation, the hoisting passageway needs to be frequently opened, making it impossible to achieve a fixed seal. This results in a large amount of dust, such as dust generated during ore unloading operations and road dust, entering the crushing workshop through the hoisting passageway. This leads to high dust concentrations, poor air quality, and serious health hazards for the workers operating within the workshop.
[0003] Existing dust control technologies for hoisting passages are relatively lacking. Generally, movable baffles are used to physically block the hoisting passage. When in use, the baffles are moved to open the hoisting passage, and when unloading ore, the baffles are covered to block the dust. However, this method only blocks dust at the millimeter level. It is difficult to block fine dust in the ambient air. A large amount of fine dust can still penetrate into the workshop environment through various poorly sealed parts of the hoisting passage, making it difficult to completely capture fine dust. Summary of the Invention

To this end, the present invention proposes a porous coupling plate for air jet uniformity and direction adjustment.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0022] Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0023] 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.
[0024] The following is a reference appendix. Figures 1-3 The description is based on a porous coupling plate 100 used for air jet equalization and direction adjustment.
[0025] The porous coupling air distribution plate 100 is applied to the parallel blowing device 210 of the parallel blowing and suction type air curtain dust removal system to adjust the airflow and temperature of the gas jet in the parallel blowing device 210.
[0026] like Figure 3 The porous coupling wind equalization plate 100 includes a main body, which includes an arc segment 10 and a straight plate segment 20 that is smoothly connected to the arc segment 10. Both the arc segment 10 and the straight plate segment 20 are provided with multiple sets of wind holes 30 that run through the thickness direction of the main body. The arc segment 10 has wind hole 30 segments with unequal spacing and the straight plate segment 20 has wind hole 30 segments with equal spacing.
[0027] According to an embodiment of the present invention, a porous coupling plate 100 for uniform airflow and direction adjustment of air jets is designed as an arc segment 10 and a straight segment 20. The arc segment 10 has unequally spaced air holes 30, while the straight segment 20 has equally spaced air holes 30. This effectively uniformly adjusts and directs the air jet in the parallel blowing device 210 of the parallel blowing and suction air curtain dust removal system, ensuring stable airflow and forming a uniform blowing and suction air curtain. In some embodiments of the present invention, such as... Figure 3 The density of the unequal-spacing air holes 30 segments is less than that of the equal-spacing air holes 30 segments. This reduces the intensity of the airflow when it directly enters the arc segment 10 of the air inlet 230 of the parallel blowing device 210 near the parallel blowing and suction air curtain dust removal system. Furthermore, through the design of the density of the unequal-spacing air holes 30 segments and the equal-spacing air holes 30 segments, the intensity of the airflow passing through the air holes 30 segments when it gradually diffuses to the equal-spacing air holes 30 segments is basically equal to the intensity of the unequal-spacing air holes 30 segments.
[0028] In some embodiments of this utility model, such as Figure 3The arc segment 10 includes a starting segment and a ending segment connected to the straight plate segment 20. The density of the air holes 30 gradually increases from the starting segment to the ending segment. In other words, the air holes 30 are distributed in a gradually coupled manner along the streamlined porous coupling air distribution plate 100, becoming denser closer to the ending segment. After the air enters from the blowing duct, it passes through this device to achieve uniform airflow adjustment, and then exits through the air outlet 240 of the blowing device in the parallel blowing and suction air curtain dust removal system, thereby forming a stable blowing and suction air curtain. In some embodiments of this utility model, such as Figure 3 The porosity of the 30 segments of unequally spaced air holes is ≤15%, and the porosity of the 30 segments of equally spaced air holes is ≥30%, meaning that the 30 segments of unequally spaced air holes become more densely packed as they are further away from the air inlet 230 of the blowing device. In some embodiments of this utility model, such as... Figure 3 Each group of air vents 30 consists of multiple vertically arranged air vents 30 evenly spaced along the width direction of the main body, thereby allowing the gas to be evenly ejected along the width direction of the porous coupled air distribution plate 100. In some embodiments of this utility model, such as Figure 3 The air vents 30 in each group of the straight plate section 20 are distributed at equal intervals d, where d is 5mm-30mm. In some embodiments of this utility model, such as Figure 3 The arc segment 10 extends gradually from the inside to the outside along the length direction to the straight plate segment 20, so that the multi-hole coupled air distribution plate 100 is streamlined, which is conducive to the gradual coupling of the air holes 30 and ensures the air adjustment and air distribution effect of the air holes 30.
[0029] Optionally, the spacing between each group of air holes 30 in arc segment 10 is distributed in an arithmetic or geometrical manner.
[0030] Taking an arithmetic distribution as an example: if the initial spacing is 16cm, then the spacing of each group of air holes extending into the straight section is 14cm, 12cm, 10cm...5cm (uniform spacing in the straight section).
[0031] Furthermore, each group of air holes 30 is distributed at equal intervals d' in the width direction of the main body, where d' is 2-10 mm. Preferably, the spacing between each group of air holes 30 in the initial segment of the arc segment 10 is greater than the spacing between each group of air holes 30 in the final segment of the arc segment 10.
[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
