Description

A spray module installed on a roadheader

technical field

The utility model relates to a dust removal device, in particular to a spray module installed on a boring machine.

Background technique

With the improvement of the degree of mechanization of the roadway, the use of high-efficiency and high-power roadheaders, conveyors and local ventilation equipment has increased the number of dust sources and the amount of dust produced in the roadway, and the dust concentration in the air in the roadway has greatly increased. The main sources of dust production in the excavation roadway include the excavation working face, the reloading points of the transportation equipment, and the secondary dust of the surrounding wall dust of the roadway, etc. Among them, the excavation working face produces the largest amount of dust.

In the safety production of the excavation face, the outstanding problems are the large amount of dust and the high degree of dispersion. Dust is one of the five major disasters in coal mines. On the one hand, dust is extremely harmful to human health, especially respirable dust. Coal miners are exposed to high-concentration dust working environment for a long time, so they are very susceptible to pneumoconiosis. On the other hand, the high concentration of dust in coal mines can easily cause explosions. Once a coal dust explosion occurs underground, it often causes heavy casualties, and even seriously destroys the mine, resulting in huge economic losses. In addition, the dust in the workplace will deteriorate the working environment, reduce visibility, affect labor productivity, increase the rate of work-related accidents, cause skin and eye diseases, and accelerate the wear and tear of mechanical equipment.

In order to reduce the dust concentration, during the tunneling work, an atomizing nozzle is generally installed at the front end of the roadheader, and the dust concentration is reduced by spraying water mist. However, the current nozzles are installed separately and arranged irregularly, so it is difficult to form an effective spraying surface and coverage density, and the effect of spraying and dust removal is not ideal.

detailed description

The concentration of dust in excavation flour is high, and it is necessary to continuously spray water mist during excavation to reduce dust. And under the environment conditions of high dust, all kinds of equipment are easy to break down. Therefore, an integrated spray module is proposed in this scheme, which sprays water mist to the front of the roadheader with a fixed structure and a well-designed angle, which not only has a good dust removal effect , and good practicability, not easy to break down.

A spraying module installed on a roadheader includes a fixed block 1 on which a plurality of installation holes 3 for fixing spray heads are distributed, and the orientations of the installation holes 3 are different.

As shown in Figure 1 and Figure 2, in order to integrate different nozzles, a fixed block 1 structure is provided in this solution. A plurality of installation holes 3 are distributed on the fixed block 1 , and the installation holes 3 are threaded holes, and the nozzles are installed in the installation holes 3 . The nozzles integrated on the same spray module have different orientations. In this way, there are multiple nozzles on one fixed block 1, and these nozzles have different orientations. Since the nozzles spray water mist as a conical surface, the front space can be effectively covered during the spraying process, making the spraying process more uniform.

For the convenience of supplying hydraulic power to the nozzle, in this solution, the fixed block 1 is provided with a water channel 4 along the length direction of the fixed block 1, and the water channel 4 is connected with the installation hole 3.

The mounting hole 3 leads directly to the water channel 4, so when the shower head is installed in the mounting hole 3, the shower head is connected with the water channel 4, so that the water flow can be stably supplied to the shower head. The biggest advantage of this is that only one water supply pipe needs to be connected to the water channel 4 of the module, which makes the structure more streamlined, the supply more convenient, and the phenomenon of damage is not easy to occur during use.

In order to effectively protect the installed nozzles, in this solution, a protective hole 2 is provided on the surface of the fixed block 1, the installation hole 3 is located in the protection hole 2, and the axis of the installation hole 3 is in line with the protection hole 2 axes coincide. In this way, after the nozzle is installed, a part of the nozzle is located in the protection hole 2, which can protect the nozzle.

For the actual situation of the driving surface, in this solution, the protective hole 2 is located on the same surface of the fixed block 1, which is a plane.

As shown in FIG. 1 and FIG. 2 , the protective holes 2 are circular in shape, and because of their different orientations, it is equivalent to cutting these protective holes 2 on one surface of the fixing block 1 . Considering that the best direction for spraying water mist is the front of the roadheader, it is better to set all the protective holes 2 on the same surface, which is convenient to control the size of the protective holes 2 and prevents the nozzles inside from being affected by the protective holes 2. influences. In order to ensure that the orientation angle between the nozzles can cover all areas, the surface should be flat, and it is easier to set the nozzles according to the calculated angle.

Since the protection hole 2 and the installation hole 3 are coaxial and correspond one-to-one, the structural features of the installation hole 3 will be further described below by limiting the position of the protection hole 2 .

As for the specific setting of the protective hole 2, as shown in Figure 2, in the protective hole 2 on the fixed block 1, the axis of a protective hole 2 located in the middle is perpendicular to the surface where the protective hole 2 is located. The angles between the axes of the remaining protective holes 2 and the normal line of the surface (the line perpendicular to the surface) are acute angles, as shown in θ ₁ , θ ₂ , θ ₃ and θ ₄ in FIG. 2 .

The total number of protective holes 2 can be an odd number or an even number, depending on the actual situation. It is an odd number in this scheme. A protection hole 2 in the middle is selected as a reference hole, and the axis of the protection hole 2 is perpendicular to the surface on which these protection holes 2 are arranged on the fixing block 1 . That is to say, the spraying direction of the nozzle in the reference hole is straight ahead. Except for the reference hole, the other protective holes 2 have different orientations, so that the spraying direction of the nozzle can cover various areas. If the number of protective holes 2 is an even number, one of the two middlemost protective holes 2 is randomly selected as the reference hole.

Furthermore, among the above-mentioned acute angles, the angles of the acute angles closer to the center of the fixed block 1 are smaller. That is to say, from the two ends of the fixed block 1 to the middle direction of the fixed block 1, the angle between the axis of the protective hole 2 (or the installation hole 3) and the surface normal is closer to the reference hole direction, and the angle between the axis and the surface normal is smaller. When the hole, the included angle is 0.

In this scheme, as shown in Figure 1 and Figure 2, the fixed block 1 is a rectangular block, and the surface on which the protective hole 2 is set is a surface along the length direction of the fixed block 1, called the first surface 101, and the first surface 101 The parallel face is the second surface 102, which is fixed to the boring machine. The fixing block 1 is provided with bolt holes for easy installation and fixing.

Example:

In this embodiment, the total length of the fixing block is 330mm, and the cross-sectional specification perpendicular to the length direction is 60*65mm, wherein the distance between the first surface and the second surface is 60mm. In this embodiment, five mounting holes are provided on the first surface, the distance between the two mounting holes at both ends is 260 mm, the distance between the two mounting holes on both sides of the reference hole is 130 mm, and the diameter of the mounting holes is 41 mm. As shown in Figure 2, θ ₁ and θ ₄ have the same angle of 21°; θ ₂ and θ ₃ have the same angle of 14°. It has been verified in practice that after the spray module is installed with a nozzle, in the actual application process, the water mist spraying surface does not leave a dead angle, the spraying is uniform, the density is basically the same, and the actual application effect is ideal.
