Description

[0001] This application hereby claims the Italian patent application filed on July 25, 2023, number [number missing].

[0002] Priority of patent number 102023000015567 is hereby incorporated in its entirety as part of this application. Technical Field

[0003] This invention relates to a mounting system, and more particularly to a mounting system and valve system for cleaning industrial filter valves. Background Technology

[0004] In the industrial sector, it is well known that specialized dust removal systems can be used to purify the air. In practice, these systems are used to filter dirty air drawn in from factories and remove dust through appropriate filter elements. In most cases, these filter elements consist of what are known as "sleeves" or "filter cartridges." These filtration stations are also equipped with special systems for cleaning the filter elements, enabling periodic intervention to remove residual dust from the filter elements.

[0005] One particular type of this cleaning device involves injecting pulses of compressed air into the filter element via electrically or pneumatically operated valves mounted side-by-side on a compressed air tank. The injected compressed air flows in the opposite direction to the normal intake airflow to be purified, causing the filter element to shake or vibrate, resulting in the shedding of dust accumulated on the outer surface of the filter element itself. The fallen dust can then be collected for recycling or disposal.

[0006] Different types of pulse valves exist depending on their operation, size, and installation type relative to the compressed air tank. For example, known valves are equipped with threaded or flanged connections that can be connected to complementary threaded joints or corresponding flanges, which protrude from the outer surface of the compressed air tank and correspond to the air outlet port.

[0007] However, these valves are not without their drawbacks, as their use inevitably involves a special connection on the storage tank corresponding to the compressed air outlet. This connection must be properly shaped and form a tight bond with the tank, for example, by welding. Therefore, using these valves necessitates additional treatment of the storage tank, leading to increased manufacturing time and overall costs.

[0008] In addition, there are known so-called "integrated" valves, which are not connected to the tank via flanges or threaded joints, but rather extend laterally through the tank itself to become practically part of it. Integrated valves specifically include a valve body that houses a valve element, such as a diaphragm solenoid valve, which is connected to the tank at a first orifice. The valve body is specifically provided with one or more inlets for compressed air from the tank to enter and outlets for compressed air to exit. The valve element is capable of controlling the flow of air from the inlet to the outlet.

[0009] The integrated valve also includes a compressed air outlet conduit, commonly referred to as a "jet conduit," which, upon installation, will pass laterally through the storage tank. The jet conduit has a first compressed air inlet and a second compressed air outlet. The first compressed air inlet can be connected, for example, by screwing into, the outlet of a valve body corresponding to a first hole on the storage tank. The second compressed air outlet passes through a second hole on the tank opposite each other in the diametrical direction and can be connected to the filter element of a dust collection system.

[0010] Therefore, the valve element is electrically controlled so that compressed air passes through the tank, through the inlet opening on the valve body, the first end of the injection duct, and is injected into the filter element after reaching the second end.

[0011] However, the use of these integrated valves has some drawbacks. In fact, compressed air storage tanks are typically elongated tubular structures with a circular cross-section, and to install each valve, two opposing holes in the diametrical direction need to be formed to connect the injection conduit into which the valve is inserted. The valve is then secured to the tank by a connecting element (called a "saddle") that is inserted into the second end of the injection conduit and contacts the outer surface of the tank. An annular nut, which can then be screwed onto the threaded section at the second end of the injection conduit, clamps the connecting element and valve body onto the tank surface where the opening is located. Appropriate seals can also be provided between the valve body and the tank, and between the connecting element and the tank.

[0012] Therefore, the use of such valves inevitably involves forming two holes in the storage tank and a complex assembly process, resulting in a total manufacturing time and cost that cannot be ignored.

[0013] Furthermore, once air is pressurized inside the tank, the opening created during valve operation causes the balance between the pressure applied to the inner surface and the opposing resistance from the tank's own walls to become unbalanced.

[0014] This imbalance will cause the tank's cross-section to become elliptical, thus being compressed along the longitudinal axis of the valve where the opening is located, and widening in a direction perpendicular to that axis. Furthermore, this ellipticity will become more pronounced as the tank thickness decreases.

[0015] Therefore, under the same pressure, it must withstand greater structural stress. In fact, the presence of two holes means removing more material, thus reducing its resistance to mechanical stress. To overcome this problem, a known solution is to insert a rod of metal or other material with a variable cross-section into the tank, with its end near the holes and positioned along the extrusion direction of the tank to prevent the tank itself from becoming elliptical. However, the space available for operation is typically very small, and it is difficult to access the area inside the tank near the rod, which further complicates the valve installation process. Summary of the Invention

[0017] Another object of the present invention is to design a valve mounting system for cleaning industrial filters that significantly reduces the work required to install valves onto storage tanks and the overall materials used, thereby significantly saving energy and raw materials, and eliminating the need for non-destructive inspection of the weld joints required by directives / regulations for pressure tanks.

Detailed Implementation

[0050] Please refer to this application in particular. Figure 1 Of Figure 6 Figure 1 indicates a valve fixing system used for cleaning industrial filters.

[0051] like Figure 1 As shown, specifically, the fixing system 1 can be used to connect the valve device V, to which the filter element to be cleaned can be connected (not shown in detail in the figure). The valve device V is a type of valve device known to those skilled in the art, used to regulate the flow rate of compressed gas to the filter element and to control the injection of compressed air pulses.

[0052] The fixed system 1 of this application includes at least one storage tank 2 for storing compressed gas. Specifically, the compressed gas may be compressed air. The storage tank 2 includes an inner surface 3 and an outer surface 4.

[0053] The storage tank 2 is provided with at least one outlet opening 5 for compressed gas. Specifically, for each valve device V, the storage tank 2 is provided with only one outlet opening 5.

[0054] The outlet opening 5 has an elongated shape extending along at least one first axis A1. Specifically, it should be noted that "elongated shape along at least one axis" refers to a non-circular, non-curved, or even non-polygonal shape, requiring that there are at least some points on the surrounding edges with different distances from the center point. Therefore, in this sense, the outlet opening 5 can have shapes such as elliptical, rectangular, or even square.

[0055] The storage tank 2 has a tubular structure extending along the relevant longitudinal axis L, and according to a preferred embodiment, the first axis A1 is substantially parallel to the longitudinal axis L. However, in some embodiments, it is not excluded that the first axis A1 is transverse to the longitudinal axis L of the storage tank 2.

[0056] Advantageously, the outlet opening 5 has a substantially symmetrical structure with respect to the plane orthogonal to the first axis A1. (Refer again...) Figure 2 In the embodiment shown, the outlet opening 5 has a substantially elliptical shape, wherein the major axis of the ellipse coincides with the first axis A1.

[0057] The fixing system 1 also includes at least one connector 6 extending along the extending axis S. The connector 6 can be partially inserted into the tank 2 through the outlet opening 5 and can be connected to a valve device V for cleaning industrial filters.

[0058] Therefore, connector 6 should have:

[0059] - Insertion portion 7, which can be inserted through outlet opening 5 and is provided with inlet port 8 for compressed gas; and

[0060] - Threaded portion 10, which is provided with an outlet 11 for compressed gas and is capable of receiving valve device V.

[0061] Input port 8 and output port 11 are aligned with each other along the extension axis S.

[0062] The insertion portion 7 has an elongated structure extending along at least one second axis A2, which is substantially perpendicular to the extension axis S.

[0063] Similar to the description of the outlet opening 5, the insertion portion 7 also has a non-circular, non-curved, or even non-polygonal shape, wherein at least some points on the surrounding edges are arranged at different distances from its center. The insertion portion 7 may also have, for example, an elliptical, rectangular, or even square shape.

[0064] like Figure 3 As shown, preferably, the insertion portion 7 has a substantially elliptical structure, the major axis of which coincides with the second axis A2.

[0065] According to the preferred embodiment shown in the accompanying drawings, the insertion portion 7 has a configuration substantially complementary to the outlet opening 5.

[0066] On the other hand, the central portion 9 and the threaded portion 10 have circular cross-sections. Furthermore, refer to the appendix... Figure 3 , 4 In the embodiment shown, at least the diameter of the central portion 9 is substantially equal to the diameter of the minor axis of the ellipse defined by the insertion portion 7.

[0067] The connecting body 6 is symmetrical with respect to at least one intermediate plane that is orthogonal to the second axis A2 and passes through the extended axis S.

[0068] The connector 6 can be positioned relative to the storage tank 2 in a free position and a constrained position.

[0069] like Figure 2 As shown, in the free position, the second axis A2 is substantially parallel to the first axis A1, and the connector 6 can move freely along a sliding direction D that is substantially parallel to the extending axis S and pass through the outlet opening 5. In practical use, the connector 6 can be inserted into / removed from the tank 2 through the outlet opening 5 when in the free position.

[0070] like Figure 4 As shown, in the constrained position, the insertion portion 7 is located inside the storage tank 2, the connecting body 6 rotates about the extension axis S by a predetermined rotation angle α, and the second axis A2 is transverse to the first axis A1. Specifically, in the constrained position, the connecting body 6 rotates about the extension axis S by a rotation angle α that is substantially equal to 90°, therefore, the second axis A2 is substantially orthogonal to the first axis A1.

[0071] Furthermore, in this position, the insertion portion 7 mates with the storage tank 2 to prevent the connector 6 from being pulled out of the storage tank 2. Therefore, in the constrained position, the connector 6 is fixed to the storage tank 2.

[0072] Advantageously, the insertion portion 7 includes at least one stop surface 12 that is capable of contacting the inner surface 3 of the tank 2 in the constrained position. The stop surface 12 prevents the connector 6 from sliding out of the tank 2 in the constrained position.

[0073] Advantageously, the stop surface 12 has a configuration substantially complementary to the inner surface 3 and is configured in the constrained position to conform to the inner surface 3. In one particular embodiment, the stop surface 12 has a convex configuration. The stop surface 12 allows for a suitable fit between the insertion portion 7 and the tank 2, and enables better dispersion of forces between them during use.

[0074] Specifically, the insertion portion 7 includes a pair of stop surfaces 12, which are arranged on opposite sides of the central portion 9.

[0075] According to a preferred embodiment of the present invention, the connector 6 further includes a central portion 9 located between the insertion portion 7 and the threaded portion 10.

[0076] Advantageously, the central portion 9 is provided with a retaining device 13 for holding the connector 6 onto the tank 2. In the constrained position, the insertion portion 7 and the retaining device 13 are configured to engage with the tank 2 to prevent the connector 6 from moving back and forth along the sliding direction D.

[0077] In other words, the insertion part 7 prevents the connector 6 from being pulled out of the storage tank 2, and the retaining device 13 prevents the connector 6 from falling into the storage tank 2.

[0078] The retaining device 13 includes at least one pair of retaining elements protruding from the central portion 9, wherein, in the constrained position, the retaining elements are capable of contacting the outer surface 4. The retaining elements are used to prevent the connecting body 6 from sliding into the interior of the tank 2 in the constrained position.

[0079] Advantageously, the elements are positioned on opposite sides of the central portion 9 and aligned with each other in a direction substantially parallel to the second axis A2.

[0080] In addition, the fixing system 1 includes at least one flange body 14 mounted around the connector 6 to place the latter in a constrained position, and also includes a locking device 16 to prevent the connector 6 from rotating about the extension axis S.

[0081] Therefore, the flange body 14 prevents the connector 6 from rotating and moving to a free position, thereby preventing it from accidentally detaching from the tank 2 during assembly and use. Furthermore, the locking device 16 also prevents the connector 6 from translating along a direction parallel to the first axis A1.

[0082] like Figure 4 As shown, in fact, in the constrained position, the special arrangement of the insertion part 7 relative to the tank 2 results in at least one pair of gaps 15 between the outlet opening 5 and the connecting body 6. Figure 5 As shown, the locking device 16 includes at least a pair of locking elements 16, each locking element 16 being matched to the size of a corresponding gap 15. However, it cannot be ruled out that the number of gaps 15 may vary depending on the shape of the insertion portion 7 and the outlet opening 5, as well as the position of the connector 6 relative to the latter, and correspondingly the number of locking elements 16 may also vary.

[0083] Advantageously, the flange body 14 includes a contact surface 17 having a shape substantially complementary to the outer surface 4 and being configured to adhere to the outer surface 4 itself.

[0084] Specifically, the contact surface 17 is concave, and the locking element 16 is connected to the contact surface 17. In particular, the locking element 16 protrudes relative to the contact surface 17.

[0085] The fixing system 1 also includes at least one sealing device 18 installed between the flange body 14 and the storage tank 2. Specifically, the sealing device 18 includes at least one O-ring.

[0086] like Figure 1As shown, the fixing system 1 may further include a fastener 19, which can be screwed onto a portion of the threaded portion 10 for securing the flange body 14 to the storage tank 2. The fastener 19 has the function of securing the flange body 14 to the storage tank 2, thereby preventing the flange body 14 from accidentally falling off the gap 15.

[0087] The function of the fixing body 19 is to firmly fix the entire fixing system 1 before connecting it to the valve device V.

[0088] Alternatively, the fixing system 1 may not be equipped with a fastener 19. In this case, the valve device V may be further configured to fix the flange body 14 to the storage tank 2.

[0089] Advantageously, the fixing system 1 also includes a sealing device 18 located between the fastener 19 and the flange body 14.

[0090] On the other hand, the present invention also relates to a valve system 20 for cleaning industrial filters.

[0091] like Figure 6 As shown, the valve system 20 of the present invention includes at least one fixing system 1 provided in one or more of the above embodiments and a valve device V for cleaning industrial filters, the valve device V being screwed onto the threaded portion 10.

[0092] Practice has proven that the present invention can achieve the intended purpose. It should be particularly emphasized that the fixing system for cleaning industrial filter valves provided by the present invention can simplify the assembly process with compressed air storage tanks, thereby significantly reducing the overall manufacturing time and cost.

[0093] In addition, this fixing system can significantly reduce the processing steps of the storage tank and the overall materials used when installing valves, thereby significantly saving energy and raw materials, and eliminating the need for non-destructive testing of the connection welds required by pressure tank directives / regulations.

[0094] In fact, after the processing of the outlet opening is completed, the fixing system only involves the assembly of the relevant components, without requiring further complex processing of the storage tank itself.

[0095] Finally, this mounting system minimizes ellipticity to avoid affecting normal operation, while eliminating the need for internal reinforcement. In fact, the mounting system provides a minimum-sized outlet opening for each valve assembly.

[0096] It should be understood that the present invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
