Description

Technical Field

[0001] This invention relates to the field of dust control technology, and more specifically, to an atomizing dust removal device. Background Technology

[0002] Dust, as one of the five major hazards in coal mines, poses a serious threat to the safe production of coal mining enterprises during the mining process. The fine dust particles generated during coal mining can remain suspended in the air for extended periods. Inhaling large amounts can easily lead to pneumoconiosis, severely harming workers' physical and mental health. Accumulated coal dust can also cause coal dust explosions, resulting in numerous casualties and property damage, making it a significant safety hazard in coal mining production. Currently, to improve the working environment in coal mines, dust suppression methods such as spraying, ventilation, coal seam water injection, dust collectors, and physicochemical dust suppression are widely used in dust control.

[0003] In spray dust suppression technologies, multiple rotating blades typically generate centrifugal force to atomize water molecules, which are then sprayed into the air to combine with airborne dust, thus achieving dust removal. However, since each blade has the same diameter, the atomized water molecules produced after the blades rotate are all of the same size. This leads to the problem of unsatisfactory spray dust suppression effects. Summary of the Invention

[0004] The main objective of this invention is to provide an atomizing dust removal device to solve the problem of unsatisfactory dust suppression effect of spray in related technologies.

[0005] To achieve the above objectives, the present invention provides an atomizing dust removal device, comprising: a container for containing liquid; a filter assembly disposed within the container; an inlet and an outlet, both disposed on the container, the inlet being below the filter assembly and the outlet being above the filter assembly; an outlet pipe, the first end of which is connected to the outlet; a pump body disposed on the outlet pipe; a fan blade atomizing assembly rotatably disposed on the outlet pipe, the fan blade atomizing assembly comprising multiple fan blades, at least some of which have different maximum radii, each fan blade having an internal receiving cavity, the second end of the outlet pipe being connected to the multiple receiving cavities; and multiple atomizing nozzles, each fan blade having at least one atomizing nozzle; wherein the fan blade atomizing assembly rotates counterclockwise.

[0006] Furthermore, the maximum radii of the multiple fan blades are all different.

[0007] Furthermore, the droplet size d produced by each fan blade satisfies the following formula: Where k is a proportionality constant, 3≤k≤4; ρ is the density of the liquid; ω is the rotational speed of the fan blade atomizing assembly; and D is the maximum diameter of the fan blade. is the surface tension of the liquid.

[0008] Furthermore, each fan blade includes a long side, a short side, and an arc-shaped segment connecting the ends of the long side and the short side, and the included angle between the long side and the short side of each fan blade is equal.

[0009] Furthermore, the maximum radius r of each fan blade satisfies the following formula: or, Where L1 is the length of the long side of the fan blade; θ1 is the angle between the line containing the maximum radius r of the fan blade and the long side; L2 is the length of the short side of the fan blade; and θ2 is the angle between the line containing the maximum radius r of the fan blade and the short side.

[0010] Furthermore, the cross-sectional area S of each fan blade is derived from the following formula: Where L1 is the length of the long side of the fan blade; θ1 is the angle between the line containing the maximum radius r of the fan blade and the long side; L2 is the length of the short side of the fan blade; and θ2 is the angle between the line containing the maximum radius r of the fan blade and the short side.

[0011] Furthermore, the fan blade atomizing assembly also includes a rotating shaft, with multiple fan blades spaced apart around the circumference of the rotating shaft. The rotating shaft has a hollow structure inside and is connected to each receiving cavity, and the water outlet pipe is connected to the hollow structure.

[0012] Furthermore, an opening is provided on the side of the rotating shaft away from the water outlet pipe, and a filter screen is installed in the opening.

[0013] Furthermore, a water-separating plate is provided inside the rotating shaft, which is spaced apart from the filter screen. The water-separating plate is located on the side of the rotating shaft near the water outlet pipe, and the area of ​​the water-separating plate is larger than the area of ​​the opening.

[0014] Furthermore, a fixing component is also provided inside the rotating shaft, which is connected between the rotating shaft and the water-blocking plate.

[0015] Furthermore, the pump body includes a pressure pump, and / or the atomizing dust removal device also includes a speed controller, which is connected to the fan blade atomizing assembly for control, and / or the atomizing dust removal device also includes a dust concentration sensor, which is disposed on the fan blade atomizing assembly.

[0016] According to the technical solution of this invention, liquid is contained in a container. A filter assembly is also provided inside the container. An inlet is located below the filter assembly, and an outlet is located above it. The first end of an outlet pipe is connected to the outlet. A pump body is installed on the outlet pipe. A rotatable fan-blade atomizing assembly is also installed on the outlet pipe. The fan-blade atomizing assembly consists of multiple fan blades, at least some of which have different maximum radii. Each fan blade has a receiving cavity inside, and the second end of the outlet pipe is connected to the receiving cavity. Each fan blade has at least one atomizing nozzle. The fan-blade atomizing assembly rotates counterclockwise. With the above arrangement, liquid can enter the container through the inlet located below the filter assembly, and then be filtered by the filter assembly to remove impurities from the liquid, preventing impurities in the liquid from clogging the fan-blade atomizing assembly and thus affecting the use of the atomizing dust removal device. The liquid filtered by the filter assembly flows out of the container through the outlet located above the filter assembly, and then flows into the pump body through the outlet pipe. The pump body can pressurize the liquid, allowing it to enter the fan blade atomizing assembly at a higher speed. After colliding with the fan blade atomizing assembly, the liquid can be dispersed into more droplets, thereby removing more dust. The fan blade atomizing assembly enables the pressurized liquid entering the assembly through the outlet pipe to be atomized into more droplets under the action of centrifugal force, effectively reducing dust. At least some of the fan blades have different maximum radii, so that when multiple fan blades rotate, they can produce droplets of different particle sizes. The atomizing nozzle can spray out the droplets, which then combine with dust in the air to achieve the purpose of dust removal. The counterclockwise rotation of the fan blade atomizing assembly creates a negative pressure zone in front of it, which can draw air to the fan blades and the rear of the fan blades. This allows the droplets to combine with more dust during airflow, thereby effectively improving the dust removal effect. Therefore, the technical solution of this application effectively solves the problem of unsatisfactory spray dust suppression effect in related technologies. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0025] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0026] like Figure 1As shown, in this embodiment, the atomizing dust removal device includes: a container 10, a filter assembly 20, a water inlet 30, a water outlet 40, a water outlet pipe 50, a pump body 60, and a fan blade atomizing assembly 70. Container 10 is used to contain liquid; filter assembly 20 is disposed inside container 10; inlet 30 and outlet 40 are both disposed on container 10, with inlet 30 located below filter assembly 20 and outlet 40 located above filter assembly 20; first end of outlet pipe 50 is connected to outlet 40; pump body 60 is disposed on outlet pipe 50; fan blade atomizing assembly 70 is rotatably disposed on outlet pipe 50, fan blade atomizing assembly 70 includes multiple fan blades 71, at least some of the multiple fan blades 71 have different maximum radii, each fan blade 71 has a receiving cavity 711 inside, second end of outlet pipe 50 is connected to multiple receiving cavities 711; multiple atomizing nozzles, each fan blade 71 has at least one atomizing nozzle; wherein, fan blade atomizing assembly 70 rotates counterclockwise.

[0027] Using the technical solution of this invention, liquid is contained in container 10. A filter assembly 20 is also provided inside container 10. An inlet 30 is located below the filter assembly 20 inside container 10, and an outlet 40 is located above the filter assembly 20. The first end of an outlet pipe 50 is connected to the outlet 40. A pump body 60 is provided on the outlet pipe 50. A rotatable fan blade atomizing assembly 70 is also provided on the outlet pipe 50. The fan blade atomizing assembly 70 consists of multiple fan blades 71, at least some of which have different maximum radii. Each fan blade 71 has a receiving cavity 711 inside, and the second end of the outlet pipe 50 is connected to the receiving cavity 711. Each fan blade 71 has at least one atomizing nozzle 80. The fan blade atomizing assembly 70 rotates counterclockwise. With the above configuration, liquid enters container 10 through inlet 30 located below filter assembly 20, and is then filtered by filter assembly 20 to remove impurities, preventing them from clogging the fan blade atomizing assembly 70 and affecting the operation of the atomizing dust removal device. The filtered liquid flows out of container 10 through outlet 40 located above filter assembly 20, and flows into pump body 60 through outlet pipe 50. Pump body 60 pressurizes the liquid, increasing its velocity as it enters fan blade atomizing assembly 70. Upon collision with fan blade atomizing assembly 70, the liquid disperses into more droplets, thus removing more dust. Fan blade atomizing assembly 70 allows the pressurized liquid from pump body 60 to atomize into more droplets under centrifugal force, effectively reducing dust. The different maximum radii of at least some fan blades 71 ensure that multiple fan blades 71 can generate droplets of different sizes when rotating. The atomizing nozzle 80 sprays out mist droplets, which then combine with dust particles in the air to achieve dust removal. The fan blade atomizing assembly 70 rotates counterclockwise, creating a negative pressure zone in front of it. This draws air towards the fan blade 71 and its rear side, allowing the mist droplets to combine with more dust particles during airflow, thus effectively improving dust removal efficiency. Therefore, the technical solution of this application effectively solves the problem of unsatisfactory dust suppression effects in related technologies.

[0028] It should be noted that the arrangement of the number of fan blades 71 and the number of atomizing nozzles 80 is not limited. For example, the center of the fan blade atomizing component 70 can also be a hollow ring, and the rotating shaft 72 can be connected to the hollow ring with a round tube. As long as the water flow can be atomized into water mist under the action of centrifugal force, it is acceptable. At the same time, the number of atomizing nozzles 80 can be increased or decreased according to the actual situation. Charged and ultrasonic processes can also be added before the water flow is atomized to improve the overall atomization effect of the device.

[0029] Preferably, the filter assembly 20 includes a microporous membrane and an ultrafiltration semi-permeable membrane. The microporous membrane is positioned above the water inlet, and the ultrafiltration semi-permeable membrane is positioned below the water outlet, with the microporous membrane positioned below the ultrafiltration semi-permeable membrane. This allows the liquid entering the container 10 to undergo two filtrations, effectively removing impurities and preventing them from affecting the dust removal function of the fan blade atomizing assembly 70.

[0030] In embodiments not shown in the figure, microporous membranes and ultrafiltration semi-permeable membranes can be replaced with water treatment ceramsite filter media. Water treatment ceramsite filter media refers to granular products made primarily from materials such as clay, fly ash, and shale, which are crushed, formulated, shaped, and then fired at high temperatures. Ceramsite has a hard surface, is spherical in shape, and possesses well-developed micropores, a large specific surface area, and high porosity, resulting in strong interception capacity and high filtration rate. Simply laying two layers of ceramsite filter media in the filter box is sufficient to filter out most impurities in the water, preventing these impurities from accumulating and clogging the nozzles, and fully meeting the requirements for spray water in underground coal mines.

[0031] like Figure 1 and Figure 3 As shown, in this embodiment, the maximum radii of the multiple fan blades 71 are all different. This arrangement allows the liquid entering the fan blade atomizing assembly 70 to generate droplets of different sizes due to the rotation of the assembly, enabling these droplets to enter the fan blades of different radii. This allows the droplets of different sizes to combine with dust particles of different sizes, achieving dust removal. Furthermore, when the fan blades 71 rotate, the different volumes of each receiving cavity 711 result in a certain difference in the particle size of the droplets ejected through the atomizing nozzle 80, further enhancing the dust removal effect by allowing them to combine with dust particles of different sizes.

[0032] like Figure 1 and Figure 3 As shown, in this embodiment, the droplet size d generated by each fan blade 71 satisfies the following formula: Where k is a proportionality constant, 3≤k≤4; ρ is the density of the liquid; ω is the rotational speed of the fan blade atomizing component 70; and D is the maximum diameter of the fan blade 71. Let be the surface tension of the liquid. Using the above formula, the maximum diameter of different fan blades 71 can be obtained according to the required droplet size, thereby enabling fan blades 71 of different sizes on the fan blade atomizing assembly 70 to effectively remove dust particles of different sizes.

[0033] It should be noted that the unit of d is meters, the unit of ρ is kilograms per cubic meter, the unit of ω is meters per second, and the unit of D is meters. The unit is Newtons per meter (N / m).

[0034] like Figure 1 and Figure 3As shown, in this embodiment, each fan blade 71 includes a long side 712, a short side 713, and an arc-shaped segment 714 connecting the ends of the long side 712 and the short side 713. The included angle between the long side 712 and the short side 713 of each fan blade 71 is equal. This arrangement allows each fan blade 71 to have a larger area, which in turn allows the receiving cavity 711 to have a larger area. That is, the receiving cavity 711 can hold more mist droplets and dust, and more mist droplets and dust can combine within the receiving cavity 711, thus improving dust removal efficiency.

[0035] Preferably, the arc segment 714 includes a first arc and a second arc. The first arc is tangent to the long side of the fan blade 71 and the second arc, and the second arc is tangent to the short side of the fan blade 71 and the first arc. Both the first arc and the second arc are located on the side of the fan blade 71 away from the center of the fan blade atomizing assembly 70.

[0036] like Figure 1 and Figure 3 As shown, in this embodiment, the maximum radius r of each fan blade 71 satisfies the following formula: or, Where L1 is the length of the long side 712 of the fan blade 71; θ1 is the angle between the line containing the maximum radius r of the fan blade 71 and the long side 712; L2 is the length of the short side 713 of the fan blade 71; and θ2 is the angle between the line containing the maximum radius r of the fan blade 71 and the short side 713. Based on the above formulas, the length L1 of the long side 712 and the length L2 of the short side 713 of the fan blade 71 can be obtained. This makes the dimensions of each fan blade 71 more accurate, allowing for a more precise determination of whether it can be placed within the required dust removal space. Furthermore, the radius r of the fan blade 71 can be derived from the maximum size of the space requiring dust removal, preventing the atomizing dust removal device from being unable to be placed within the required space and affecting its operation.

[0037] It should be noted that the maximum diameter D of the fan blade 71 is twice the maximum radius r of the fan blade. L1 and L2 are in meters. θ1 and θ2 are in degrees.

[0038] Preferably, the multiple fan blades 71 are evenly distributed on the water outlet pipe 50, and the included angle between two fan blades 71, that is, the included angle between the lines containing the maximum radii of the two fan blades 71, is... θ1+θ2=θ, where θ is the angle between the long side 712 and the short side 713 of each fan blade 71. n represents the number of fan blades 71. This allows droplets of different sizes to enter the different receiving cavities 711 more effectively. The value can be 1, Of course, it can also be other values.

[0039] like Figure 1 and Figure 3 As shown, in this embodiment, the cross-sectional area S of each fan blade 71 is obtained according to the following formula: Where L1 is the length of the long side 712 of the fan blade 71; θ1 is the angle between the line containing the maximum radius r of the fan blade 71 and the long side 712; L2 is the length of the short side 713 of the fan blade 71; and θ2 is the angle between the line containing the maximum radius r of the fan blade 71 and the short side 713. Using the above formulas, the cross-sectional area S of each fan blade can be obtained, facilitating the calculation of the dust removal efficiency of the atomizing dust removal device.

[0040] It should be noted that the unit of S is square meters.

[0041] Specifically, when the droplet diameter d is 20 micrometers or 30 micrometers, Pick When k is 3.5, the values ​​of r, L1, L2, and S are shown in the table below:

[0042] 20 0.314 0.24 0.13 0.045 30 0.1395 0.107 0.058 0.009

[0043] like Figure 2 As shown, in this embodiment, the fan blade atomizing assembly 70 also includes a rotating shaft 72. Multiple fan blades 71 are spaced apart and arranged circumferentially on the rotating shaft 72. The rotating shaft 72 has a hollow structure 721 inside and communicates with each receiving cavity 711. The water outlet pipe 50 communicates with the hollow structure 721. The rotating shaft 72 provides an installation position for the fan blades 71, allowing them to be fixedly mounted on the rotating shaft 72, preventing the fan blades 71 from changing position during the use of the atomizing dust removal device and affecting its operation. The hollow structure 721 communicates with the receiving cavity 711, and the water outlet pipe 50 communicates with the hollow structure 721, allowing the liquid in the water outlet pipe 50 to enter different receiving cavities 711 through the hollow structure 721. This allows droplets of different particle sizes to combine with dust in different receiving cavities 711, achieving the purpose of dust removal.

[0044] like Figure 2 As shown, in this embodiment, an opening 722 is provided on the side of the rotating shaft 72 away from the water outlet pipe 50, and a filter screen 7221 is provided in the opening 722. The fan blades 71 rotate counterclockwise, creating a negative pressure zone on the side of the opening 722 away from the water outlet pipe 50. This allows dust and air in the air to enter the rotating shaft 72 through the filter screen 7221. Under the centrifugal force of the rotating fan blades 71, dust particles of different sizes can enter the fan blades 71 with different maximum radii r. Simultaneously, the dust and air entering the receiving cavity 711 can shear the liquid, improving the atomization effect of the droplets. The filter screen 7221 can block large dust particles from entering the receiving cavity 711 and preventing them from clogging the atomizing nozzle 80.

[0045] Specifically, dust particles of different sizes are thrown into different receiving cavities 711 under the action of centrifugal force. The smaller the dust particle size, the smaller the gravity, and the more obvious the effect of centrifugal force, and the greater the throwing distance. Small dust particles are more likely to be thrown into the fan blade 71 with the largest maximum radius r and combine with the mist droplets, while large dust particles are more likely to be thrown into the fan blade 71 with the smallest maximum radius r and combine with the mist droplets, thereby improving the dust capture efficiency of the fan blade 71.

[0046] like Figure 2 As shown, in this embodiment, a water-separating plate 723 is provided inside the rotating shaft 72. The water-separating plate 723 is spaced apart from the filter screen 7221. The water-separating plate 723 is located on the side of the rotating shaft 72 near the water outlet pipe 50, and the area of ​​the water-separating plate 723 is larger than the area of ​​the opening 722. Through the above arrangement, the water-separating plate 723 can block the liquid flowing out of the water outlet pipe 50 along the axial direction of the rotating shaft 72, so that the liquid flowing out of the water outlet pipe 50 can avoid flowing out of the fan blade atomizing assembly 70 through the opening 722. This allows the liquid to be atomized into droplets of different particle sizes in the fan blade 71 under the action of centrifugal force, thereby removing dust of different particle sizes. It also prevents the dust that has entered the rotating shaft 72 from being washed out when the liquid flows out of the fan blade atomizing assembly.

[0047] like Figure 2 As shown, in this embodiment, a fixing member 724 is also provided inside the rotating shaft 72, which is connected between the rotating shaft 72 and the water-separating plate 723. The fixing member 724 enables the water-separating plate 723 to be fixed on the rotating shaft 72, preventing the water-separating plate 723 from changing position during the rotation of the rotating shaft 72, thus affecting the use of the fan blade atomizing assembly 70.

[0048] like Figure 1 As shown, in this embodiment, the pump body 60 includes a pressurizing pump 61, and the atomizing dust removal device also includes a speed controller 90, which is connected to the fan blade atomizing assembly 70. The atomizing dust removal device also includes a dust concentration sensor 100, which is mounted on the fan blade atomizing assembly 70. The pressurizing pump 61 pressurizes the liquid in the water outlet pipe 50, allowing the liquid to impact the water separator 723 and disperse into droplets of different sizes. These droplets then enter the receiving cavity 711 and combine with dust particles of different sizes to achieve dust removal. The speed controller 90 controls the rotation speed of the fan blade atomizing assembly 70, thereby atomizing the liquid entering the fan blade 71 into droplets of different sizes, which then combine with dust particles of different sizes, avoiding water waste and improving dust removal efficiency. The dust concentration sensor 100 can detect the dust concentration in the air and transmit the detection result to the speed controller 90, so that the speed controller 90 can control the rotation speed of the fan blade atomizing component 70 according to the dust concentration to generate droplets of different sizes and achieve better dust removal effect.

[0049] Preferably, the speed controller 90 and the dust concentration sensor 100 are wirelessly connected. The speed controller 90 is pre-set with different concentration ranges, and automatically adjusts the rotation speed ω of the fan blade atomizing assembly 70 according to the detected dust concentration value. A magnetizing assembly, including an N-pole magnet and a S-pole magnet, is also provided inside the receiving cavity 711. The magnetizing assembly can magnetize the droplets into smaller droplets, thereby binding more dust and further improving the dust removal effect. A dust filter is also provided inside the receiving cavity 711 to prevent the dust-droplet mixture from flowing out of the fan blade 71 and affecting the dust removal effect of the atomizing dust removal device, and also to prevent the dust-droplet mixture from clogging the atomizing nozzle 80. An exhaust port is also provided on the fan blade 71 so that the dust-droplet mixture in the receiving cavity 711 can be discharged when the fan blade 71 stops rotating.

[0050] Of course, N-pole and S-pole magnets can also be used on both sides of the fan blades to make them magnetic fan blades, which eliminates the need to add magnetization components.

[0051] Specifically, based on the size of the space requiring dust removal by the atomizing dust removal device, the radius r of the fan blade can be initially determined. This leads to the determination of the length L1 of the long side 712 of the fan blade 71, the length L2 of the short side 713 of the fan blade 71, the angle θ1 between the line containing the maximum radius r of the fan blade 71 and the long side 712, and the angle θ2 between the line containing the maximum radius r of the fan blade 71 and the short side 713. θ ranges from 30 to 60 degrees, and the number of fan blades n ranges from approximately 5 to 10.

[0052] It should be noted that in this embodiment, the liquid is water. Of course, in other embodiments, the liquid can be other solutions.

[0053] like Figures 1 to 3 As shown, in this embodiment, the atomizing dust removal device is used as follows:

[0054] 1. Liquid enters container 10 through inlet 30. Since inlet 30 is located below microporous membrane, ultrafiltration semipermeable membrane and outlet pipe 50, some large particles of impurities in the liquid will settle at the bottom of the container due to gravity. Subsequently, microporous membrane further intercepts larger solid particles in the liquid, such as rust, suspended matter, silt, microorganisms and other impurities. Then, ultrafiltration semipermeable membrane thoroughly filters out bacteria, viruses, colloids, rust and other impurities in the liquid. Finally, the filtered liquid flows from outlet pipe 50 to pressure pump 61.

[0055] 2. The liquid is pressurized by the pressure pump 61 and enters the containment chamber 711 with a certain initial velocity. The liquid is atomized into droplets by the centrifugal force generated by the high-speed rotation of the fan blade 71. The droplets combine with the dust that enters the containment chamber 711 through the filter screen 7221. The uncombined droplets are sprayed out from the atomizing nozzle 80 and combine with the dust in the air to achieve dust suppression again.

[0056] 3. The dust concentration sensor 100 monitors the dust concentration of the surrounding environment in real time and feeds the data back to the speed controller 90. The speed controller 90 compares the pre-set dust concentration range with the measured dust concentration data of the environment, and determines the appropriate rotational angular velocity ω of the fan blade 71 based on the dust concentration range. By adjusting the rotational angular velocity ω of the fan blade 71, the dust removal effect of the atomizing dust removal device is always kept at the best state, thereby achieving the purpose of dust control.

[0057] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0058] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
