Description

[Technical Field]

[0001] This invention relates to a ventilation device for spraying barrier products. [Background technology]

[0002] Mineral wool is an excellent heat and sound insulator because it contains intertwined mineral fibers that give it a porous and elastic structure. Such a structure allows it to trap air and absorb or reduce noise. Furthermore, mineral wool is mainly manufactured from mineral materials, particularly natural materials or recycled materials (recycled glass), and is therefore attractive from the standpoint of environmental balance. And because mineral wool is based on materials that are inherently non-combustible, it does not ignite fire or spread flames. Preferably, mineral wool is selected from glass wool or rock wool.

[0003] There are bulk-packed products that take the form of small bundles of intertwined fibers forming centimeter-scale particles, without any binders to secure the fibers in the bundles.

[0004] The manufacture of bulk mineral wool involves at least the following steps: - The process of melting raw materials such as glass in a melting furnace. - The process of fiberization, - The process of forming a mat of mineral wool, - A process of forming small nodules (nodulation) using grinding.

[0005] The production of bulk mineral wool may further include the following steps: - A step of coating with an antistatic agent and / or a binding agent before, simultaneously with, or after the formation of small clumps, and / or - The packaging process.

[0006] At the end of the clumping process, the mineral wool is in the form of clumps or flakes. Therefore, the mineral wool can be used as a bulk barrier product or bulk barrier material by spreading it, spraying it, or using it to fill cavities. Bulk barrier materials correspond to various materials in the construction field that are provided in the form of small particles, with textures ranging from granular to flaky.

[0007] Mineral wool is advantageously used in the form of small lumps or flakes, as a main component of bulk insulation products, for hard-to-reach spaces such as attic floors where development has not been done or access is difficult.

[0008] These bulk-packed sealing products are typically applied by mechanical spraying using a sprayer that can spray the sealing product onto the surface from the outlet pipe or inject it into the cavity.

[0009] Therefore, bulk-packed insulation products are primarily installed by spraying them directly into the space to be insulated, such as attic spaces, or by injecting them into wall cavities.

[0010] Bulk-packed barrier products are also known as spray-on barrier products.

[0011] The sprayed insulation material needs to be as homogeneous as possible to avoid thermal bridging and thereby improve thermal performance. However, when the insulation material is sprayed, the mineral wool, in the form of small lumps or flakes, is not perfectly homogeneous, regardless of the diameter of the outlet pipe. The thermal conductivity of the resulting insulation material is not optimized.

[0012] In this regard, as shown in Figure 1, there is a chamber 1 having an inlet opening 2 and an outlet opening 3, and its structure allows the flakes 4 to be aerated under the effect of a turbulent gas flow that enables the flakes to move randomly within the chamber for a predetermined time before leaving the chamber.

[0013] However, these chambers for aerating wool cannot solve all the problems operators may encounter in the field. This is because, while the chambers allow flakes to aerate to improve their thermal properties, they are bulky and difficult to handle, thus hindering a good spray.

[0014] This bulkiness is even more problematic when the operator has to move around with the ventilation chamber to spray wool across the entire surface of the space that needs to be sealed. [Overview of the Initiative]

[0028] According to one example, the chamber includes an inlet surface for an inlet opening, an outlet surface for an outlet opening, two side surfaces, an upper surface, and a lower surface, and the at least one shutter is disposed on the outlet surface.

[0029] According to one example, the chamber includes an inlet surface for an inlet opening, two side surfaces, an upper surface, and a lower surface, the upper and lower surfaces being designed to converge towards each other while leaving a space that functions as an outlet opening, and the at least one shutter is disposed on the upper or lower surface.

[Modes for carrying out the invention]

[0036] Detailed description of the invention Figures 2 and 3 show an apparatus 10 for preparing a wool-based barrier product according to the present invention. The apparatus 10 comprises a chamber including an inlet opening 101 and an outlet opening 103. A gas flow f is introduced into the chamber 100 through the inlet opening, and this gas flow f is produced by means P for generating the gas flow. The inlet opening 101 also allows for the introduction of material L. This material L is wool in the form of flakes or lumps, such as rock wool, glass wool, or cellulose wool. The length of these mineral wool lumps or flakes is 0.05 to 5 cm, in particular 0.1 to 1 cm. These flakes or lumps are formed from intertwined fibers in the form of small bundles, small rovings, or "pillings." This material L is introduced into the chamber via means for introducing wool into the chamber in the form of flakes or lumps. Thus, the material L and the gas flow are introduced into the chamber 100 via a pipe t, which is itself connected to means P for generating the gas flow, thereby forming a barrier spray system. Material L can be introduced into the gas flow beforehand. The chamber 100 further includes means for creating entrainment of wool in one direction A and entrainment of wool in the opposite direction B, which is opposite to direction A, so that there is at least one plane in the chamber that is perpendicular to direction A, where the wool entrained in direction A intersects with the wool entrained in the opposite direction B. The means for creating entrainment of wool in one direction A and entrainment of wool in the opposite direction B, which is opposite to direction A, in the chamber depends, for example, on the shape and size of the chamber. The outflow is sprayed through the outlet opening 103.

[0037] In the case of chamber 100, the latter is designed such that the inlet opening 101 and the outlet opening 103 are located opposite each other on the chamber. Thus, the inlet opening is located on the inlet surface 100a, while the outlet opening is located on the outlet surface 100b. Preferably, the inlet opening 101 and the outlet opening 103 face each other. The chamber is such that at least the area of ​​the inlet opening is different from the area of ​​the inlet surface, meaning that the area of ​​the inlet opening is smaller than the area of ​​the inlet surface. Preferably, the area of ​​the inlet opening is equal to half the area of ​​the inlet surface, preferably equal to one-third, one-quarter, or one-fifth of the area of ​​the inlet surface. Preferably, the area of ​​the outlet opening is also different from the area of ​​the outlet surface. This chamber structure allows for turbulence of the gas flow circulating within it. In the case of a chamber where the inlet opening has the same area as the inlet surface and the outlet opening has the same area as the outlet surface, the incoming gas flow is not subjected to turbulence for aerating the wool flakes, and the flow enters and then exits without residence time in the chamber.

[0038] In the first configuration, as can be seen in Figure 4a, the chamber 100 further includes at least two sides 100c, a top surface 100d, and a bottom surface 100e. Thus, in this first configuration, when viewed from the side, the chamber may have a square, rectangular, or trapezoidal longitudinal section.

[0039] In the second configuration, which can be seen in Figure 4b, the chamber 100 includes at least two sides 100c and a top surface 100d and a bottom surface 100e. An outlet surface has been omitted, taking into account the top and bottom surfaces. This is understood to mean that the top surface 100d and the bottom surface 100e are positioned such that an outlet surface is unnecessary. For this purpose, the top and bottom surfaces are positioned such that the chamber has a triangular longitudinal section when viewed from the side. For this purpose, the top and bottom surfaces converge toward each other. Such a triangular longitudinal section allows for the placement of an outlet opening at the intersection between the top and bottom surfaces.

[0040] In the third configuration, which can be seen in Figure 4c, the chamber 100 includes at least two sides 100c, a top surface 100d, and a bottom surface 100e. The exit surface 100b is divided into two parts 101b' that converge to create a triangular longitudinal section locally / partially. Such a triangular longitudinal section allows for the positioning of the exit opening 103 at the intersection between the two parts forming the exit surface.

[0041] The chamber is preferably 5 to 90 dm 3 It has dimensions that allow it to have a volume of [a certain value].

[0042] The outlet opening 103 may have any shape, such as a circular shape 103a. Preferably, the outlet opening is in the form of a slot 103b. This slot extends horizontally to the floor surface of the chamber on the side opposite to the inlet surface. This slot extends over a portion of the width of the chamber or over the entire width of the chamber. The height of this slot is 0.1 to 3 cm, preferably 0.5 to 2 cm.

[0043] The advantage of slot 103b is that it allows the flakes to be released over a wider area, thereby enabling coverage of a large area.

[0044] Cleverly, the chamber 100 is equipped with a system 200 for adjusting the outlet opening, which allows control over the area of ​​the outlet opening 103. Specifically, by controlling the area of ​​the outlet opening 103, the outlet velocity of the flow can be changed. This is because the chamber is governed by the principle that a mass flow of air is conserved, and as a result, the outlet flow is constant, and it is the velocity of this flow that changes. Increasing this velocity allows the exiting flakes to be sprayed over a greater distance. This allows the operator to spray flakes of the barrier product over a larger radius without moving. According to the present invention, if the flow enters the chamber at a velocity of 8-30 m / s, the chamber equipped with the system 200 for adjusting the outlet opening allows the outlet flow velocity to be 5-60 m / s. Specifically, increasing the velocity allows spraying of flakes over a larger area, while lower velocities allow avoiding difficult movement. Thus, it will be understood that the system 200 for adjusting the outlet opening is such that it allows the outlet opening to be adjusted from 0-100%. Therefore, the exit opening can be 100% open, closed (i.e., 0% open), or can take any position between 0 and 100%.

[0045] Therefore, with this in mind, the outlet opening 103 has a larger area than the inlet opening 101. Thus, the system 200 for adjusting the outlet opening allows the area of ​​the outlet opening 103 to be larger than the area of ​​the inlet opening, the same as the area of ​​the inlet opening, or smaller than the area of ​​the inlet opening. This means that it is possible for the outlet opening to have a larger area than the inlet opening.

[0046] In this way, material L is aerated in the chamber. At the outlet, the barrier product obtained after the aeration process has a low density, particularly for glass wool-based products, which is about 5-15 kg / m³. 3 For rock wool-based products, the density is approximately 15-50 kg / m3 It has a low density.

[0047] To enable this change in the area of ​​the exit opening 103, the system 200 for adjusting the exit opening includes at least one shutter 201, as can be seen in Figure 5. This shutter is mounted to occupy multiple different positions.

[0048] In the first embodiment, the movable shutter 201 is operated manually.

[0049] In the first embodiment, as can be seen in Figures 6a, 6b, and 7, adjustment is achieved by an interlocking device. Specifically, the system 200 for adjusting the exit opening includes means 203 for positioning the shutter 201 using an interlocking system 210. In this first embodiment, the chamber 100 has a plurality of holes 211, preferably blind holes, on one of its faces. These holes 211 extend along at least one line, preferably two parallel lines perpendicular to the width of the chamber. These blind holes are spaced at regular intervals. The two parallel lines are spaced at least equal to half the width of the chamber between them.

[0050] The movable shutter 201 includes at least one set of studs 213. This set of studs 213 is used when the shutter 201 includes a plurality of holes 211 arranged in the form of a single line. When the shutter 201 includes holes 213 arranged to form two lines, the shutter 201 includes at least one set, or at least two sets of studs 213. Each stud extends perpendicular to the surface of the shutter.

[0051] When the holes 211 are arranged in a single line, the set of studs 213 is arranged such that the spacing between two studs allows the latter to fit into two holes that are not necessarily adjacent.

[0052] When the holes 211 are arranged in the form of two lines, the studs 213 are arranged such that the spacing between two sets of studs 213 is the same as the spacing between two parallel lines of holes 211. Furthermore, the two sets are positioned relative to each other so that each stud 213 can fit into a hole 211. Thus, by arranging the studs in different holes along parallel lines, it becomes possible to change the position of the shutter 201. In this way, the holes and studs form a means 203 for positioning the shutter. Thus, the position of the shutter 201 relative to the holes 211 can be adjusted. The holes 211 in one line are preferably arranged at regular intervals to allow linear adjustment of the exit opening. The user can also move the shutter 201 from one end position to another end position without passing through an intermediate position.

[0053] In a second embodiment, as can be seen in Figures 8 and 9, the means 203 for positioning the shutter utilizes a rail system 220. Such a system is designed such that the chamber 100 has two parallel rails on at least one of its surfaces for guiding the shutter 201, and thus the shutter can move in translational motion.

[0054] In one example, each rail 221 has a C-shaped longitudinal section. The rails are arranged so that the C-shaped longitudinal sections face each other. The spacing is such that it fits the rails 221 so that the shutter 201 slides. Through holes with screws (not shown) can be used to fix the shutter in place, and by tightening the screws, it can be tightened, thereby fixing the shutter in place. Thus, the user can position the shutter 201 as desired and then fix it in place.

[0055] In another example, the rail system 220 includes receiving rails 223. Each rail 223 has a U-shaped longitudinal section. The rails 223 are arranged so that their U-shaped longitudinal sections are spaced apart from each other and function as receiving rails. The shutter 201 further includes two longitudinal rails known as sliding rails 224. The arrangement of the sliding rails 224 of the shutter 201 is such that the sliding rails 224 of the shutter fit into the U-shaped rails 223 so that they slide. In an example not shown, there are through holes with screws for fixing in place, which can be tightened by screwing the screws, thereby fixing the position of the shutter.

[0056] In the modification shown in Figure 10, the indexing means 205 is used to fix the position of the shutter. For this purpose, two sets of teeth 205a and 205b are arranged, one set 205a on the shutter, which engages with a set of teeth 205b on the receiving rails 221 and 223. The teeth are designed to engage with each other and allow the shutter to move along the rails in two directions of movement. Thus, this movement of the shutter allows it to more or less block the exit opening, and the teeth allow for controlled linear movement of the shutter.

[0057] In a second embodiment, the movable shutter 201 is electrically driven. This means that the shutter is driven by a drive means 230. These drive means 230 include at least one motor 231, at least one sawtooth engaging element 232, and at least one gear element 233 for creating a mechanical connection between the motor and the sawtooth engaging element.

[0058] In the first embodiment, the chamber comprises two parallel rails for guiding the shutter.

[0059] In one example, as can be seen in Figures 11 and 12, each rail 223 has a U-shaped longitudinal section. The rails 223 are arranged such that the U-shaped longitudinal sections are spaced apart from each other. The shutter includes two longitudinal rails 224. The arrangement of the rails 224 of the shutter is such that the rails 224 of the shutter fit into the U-shaped rails 223 so that they slide. The shutter 201 is dimensional such that a portion 201' protrudes or projects outward from the chamber, more specifically, protrudes or projects outward from the chamber on the side. Advantageously, this arrangement allows for the presence of a sawtooth-shaped engaging element 232 that extends linearly in the protruding portion of the shutter. This sawtooth-shaped engaging element 232 cooperates with a gear element 233 located on the side of the chamber, the gear element being directly or indirectly connected to the shaft of a motor 231. When this motor shaft rotates, the gear element rotates, and its teeth engage with the sawtooth-shaped engaging element of the shutter to move the latter.

[0060] In another example, as can be seen in Figure 13, each rail 221 has a C-shaped longitudinal section. The rails 221 are arranged such that the C-shaped longitudinal sections are spaced apart from each other. The shutter 201 is designed to slide in accordance with the C-shaped rails. The shutter 201 includes a linearly extending sawtooth engagement element 232 on its surface facing the chamber. Facing this tooth of the shutter, the chamber 100 includes a slot 100' through which at least one portion of a gear element 233 passes, and this gear element 233 cooperates with the sawtooth engagement element 232 of the shutter 201. Because the gear element is connected directly or indirectly to the motor shaft, when this motor shaft is rotated, the gear element rotates and its teeth engage with the sawtooth engagement element of the shutter to move the latter.

[0061] The serrated engagement element 232 may be in the form of teeth, or a plurality of through notches or blind notches into which the teeth of the pinion fit.

[0062] In the first configuration, placing one movable shutter 201 on the exit surface reduces the size of the slot, thereby increasing the spray range of the blocking flakes.

[0063] In the second and third configurations, the area of ​​the outlet opening 103 when viewed from the front of the latter can be reduced by placing one movable shutter 201 on the upper or lower surface, or on one of the parts of the outlet surface. Nevertheless, with one shutter, a portion of the sprayed flake flow will be directed upward or downward depending on the position of the shutter. Therefore, a shutter 201 placed on the upper part of the chamber 100 will direct the flow downward, and vice versa.

[0064] In a modified embodiment, as can be seen in Figure 14, the chamber 100 is equipped with two shutters 201, which are movable.

[0065] Therefore, in the first embodiment, as can be seen in Figure 15, the two shutters 201 can be moved manually and independently.

[0066] In the second embodiment, as can be seen in Figure 16, each shutter can be controlled by its own motor 231 so that the movement of each shutter is independent.

[0067] This independence of movement is advantageous in the second and third configurations of the chamber, because in these configurations, the flow is redirected by the presence of a single shutter. When two shutters that can move independently are present, this redirection of air can be controlled to redirect it upwards or downwards by changing the movement of each shutter. Additionally, it is advantageous that the two shutters can be moved simultaneously so that their movements are identical.

[0068] According to the alternative shown in Figure 17, the two shutters 201 are controlled by a single motor 231. For this purpose, the teeth of each shutter engage with a pinion. These pinions are part of a gearing ring mechanically connected to the single motor 231. Thus, when the motor rotates, the pinions of the gearing ring rotate, and more specifically, the pinions engage with the teeth of the shutters. This alternative allows the two shutters 201 to move simultaneously at the same speed if the pinions driving the two shutters 201 are identical.

[0069] In this alternative, the operator cannot direct the outlet flow downward or upward, but the risk of the flow being directed upward or downward is avoided because uniformly adjusted slots can be used.

[0070] Of course, the present invention is not limited to the illustrated examples, but can be modified and altered in various ways that will be obvious to those skilled in the art.

[0071] Specifically, it is also possible to manually operate the gear train that controls the movement of one or more shutters. For this purpose, one of the gears is equipped with a grip element that allows the operator to act on the gear train to control the movement of one or more shutters.

[0072] Naturally, the present invention is not limited to an exit opening in the form of a slot. The exit opening may have a circular or parallelepiped shape. Therefore, the system for adjusting the exit opening is adapted according to the shape of the exit opening. For example, for a circular opening, as can be seen in Figure 19, the system for adjusting the exit opening includes a shutter or diaphragm 203.

[0073] Similarly, one or more shutters may move in different directions. Specifically, in the example above, the shutters move in a direction substantially parallel to the direction of the chamber's length. However, as can be seen in Figures 18a and 18b, the direction in which one or more shutters move is considered to be perpendicular to the chamber's length.
