Description

Technical Field

[0001] This utility model relates to the field of industrial ventilation technology, and more specifically, to a ventilation duct for industrial ventilation. Background Technology

[0002] Industrial exhaust ventilation is a technical measure that uses ventilation equipment to remove polluted air from industrial sites and introduce fresh air in order to improve the working environment. Its core principle is to achieve gas exchange by utilizing air convection and negative pressure effects. The main equipment includes exhaust fans, negative pressure fans, etc., and it is widely used in factories, workshops, warehouses and other scenarios.

[0003] However, existing technologies have some problems: existing industrial exhaust ventilation ducts usually use multiple sets of pipes welded into a whole. Although this ensures the sealing of the pipes, dust, smoke, oil mist and other pollutants are easy to accumulate inside the pipes during actual use, which leads to poor ventilation. Existing pipes are difficult to clean. At the same time, the integral welding makes it inconvenient to install the pipes, and it is difficult to replace and repair damaged parts of the pipes. Therefore, we propose an industrial exhaust ventilation duct. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for ventilation ducts used in industrial exhaust systems.

[0005] According to a first aspect of the present invention, an industrial exhaust ventilation duct is provided, comprising multiple sets of pipes, wherein the multiple sets of pipes are detachably connected, an inner connecting ring is movably connected between every two sets of pipes, a rubber pad is fixedly connected to the outer wall of the inner connecting ring, a cleaning component is provided on the pipe, an air inlet pipe is detachably connected to one end of one set of pipes, an air outlet component is provided at one end of another set of pipes, and a fixing component is provided on the pipe, the fixing component being used to connect the air inlet pipe, the pipe and the air outlet component.

[0006] Optionally, the cleaning component has an observation window, and an observation hole is provided on the upper side of the pipe. The observation window is rotatably connected to the observation hole, and a sealing ring is fixedly connected to one side of the observation window.

[0007] Optionally, the pipe has a groove, a fixing pin is slidably connected in the groove, the observation window has a slot, the fixing pin is engaged in the slot, a spring is fixedly connected to the fixing pin, the spring is fixedly connected to the inner wall of the groove, and a knob is rotatably connected to one end of the fixing pin.

[0008] Optionally, the cleaning assembly further includes a barrier ring, which is fixedly connected to the inner wall of the pipe. A through hole is provided on the other side of the pipe, and a collection box is fixedly connected to the inner wall of the through hole. A door is detachably connected to the collection box.

[0009] Optionally, an air inlet is provided on one side of the air inlet pipe. The air inlet is square, and multiple sets of railings are fixedly connected to the inner wall of the air inlet. The multiple sets of railings are evenly distributed on the inner wall of the air inlet.

[0010] Optionally, the air outlet assembly includes a connecting pipe, which is detachably connected to a pipeline via a fixing component. A flexible hose is fixedly connected to the connecting pipe, and an air outlet pipe is fixedly connected to the flexible hose.

[0011] Optionally, the fixing component includes a first fixing ring and a second fixing ring, the first fixing ring and the second fixing ring being rotatably connected, and both the first fixing ring and the second fixing ring having a slot, the slot being chamfered.

[0012] Optionally, each end of the multiple sets of pipes is fixedly connected with a retaining ring, and the rubber pad is disposed between two sets of the retaining rings, with the retaining ring and the rubber pad engaging in a groove.

[0013] Optionally, the first fixing ring has a connecting groove, a fixing screw is rotatably connected in the connecting groove, a fixing seat is threaded onto the fixing screw, and a knob is fixedly connected to the fixing seat.

[0014] Optionally, a fixing frame is fixedly connected to the outer wall of the pipe, and a hanging ring is fixedly connected to the fixing frame.

[0015] According to one embodiment of this disclosure, when debris is observed to be accumulating inside the pipe through the observation window, the ventilation system is turned off. By turning the knob, the fixing pin is no longer pushed. At this time, the fixing pin will retract into the groove due to the spring's rebound force, causing the fixing pin to disengage from the observation window's slot. Thus, the fixing pin no longer fixes the observation window, and the observation window can be rotated to open it. Then, the pipe can be cleaned, and the debris inside can be removed. At the same time, the box door can be disassembled to allow the debris to be discharged from the collection box, making cleaning more convenient. After cleaning, the box door and observation window can be fixed back together to form a seal.

[0016] This invention involves fastening the first and second fixing rings onto a fixing ring, then rotating the fixing screw to move the fixing seat into the fixing groove of the second fixing ring, and then rotating the knob to rotate the fixing seat. This allows the fixing seat to lock the second fixing ring in the threaded engagement with the fixing screw. The fixing assembly enables quick splicing and disassembly of the pipe, making the installation of the ventilation pipe quick and easy. It also allows for rapid replacement of damaged individual pipes, reducing downtime and improving emission efficiency.

[0029] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, 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 present invention.

[0030] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0032] In all the 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.

[0033] like Figure 1-9 As shown, an industrial exhaust ventilation duct includes multiple sets of pipes 1. The pipes 1 are made of galvanized steel, and the main function of the pipes 1 is to form a ventilation channel to exhaust gas.

[0034] Furthermore, multiple sets of pipes 1 are detachably connected, and an inner ring 2 is movably connected between every two sets of pipes 1. A rubber gasket 3 is fixedly connected to the outer wall of the inner ring 2 to ensure the connection is sealed.

[0035] Furthermore, a cleaning component 4 is provided on the pipe 1, with an observation window 41 on the cleaning component 4. An observation hole is provided on the upper side of the pipe 1, and the observation window 41 is rotatably connected to the observation hole. A sealing ring 42 is fixedly connected to one side of the observation window 41.

[0036] Furthermore, a groove is provided on the pipe 1, and a fixing pin 43 is slidably connected in the groove. A slot is provided on the observation window 41, and the fixing pin 43 is engaged in the slot. A spring 44 is fixedly connected to the fixing pin 43, and the spring 44 is fixedly connected to the inner wall of the groove. A knob 45 is rotatably connected to one end of the fixing pin 43.

[0037] Specifically, the observation window 41 is equipped with transparent glass, which allows observation through the observation hole to check whether there is any leakage or accumulation of pollutants such as dust, smoke, or oil mist inside the pipe 1, so as to take timely measures to prevent the spread of pollution or damage to the equipment.

[0038] Furthermore, the cleaning component 4 also includes a barrier ring 46, which is fixedly connected to the inner wall of the pipe 1. A through hole is provided on the other side of the pipe 1, and a collection box 47 is fixedly connected to the inner wall of the through hole. A box door 48 is detachably connected to the collection box 47, and the box door 48 is detachably connected to the collection box 47 by fixing bolts.

[0039] Specifically, the barrier ring 46 can block some debris to prevent it from flowing into subsequent equipment and affecting its operation. At the same time, the blocked debris can fall into the collection box 47 for collection, and then be discharged by disassembling the box door 48.

[0040] Furthermore, when it is observed through the observation window 41 that there is debris accumulation inside the pipe 1, the ventilation system is turned off, and the knob 45 is turned so that it no longer pushes the fixing pin 43. At this time, the fixing pin 43 will retract into the groove due to the rebound force of the spring 44, so that the fixing pin 43 disengages from the slot of the observation window 41, and thus the fixing pin 43 no longer fixes the observation window 41. At this time, the observation window 41 can be turned to open it, and then the pipe 1 can be cleaned to remove the debris inside. At the same time, the box door 48 can be disassembled to allow the debris to be discharged from the collection box 47, making cleaning more convenient. After cleaning, the box door 48 and the observation window 41 can be fixed again to form a seal.

[0041] Furthermore, one end of a set of pipes 1 is detachably connected to an air inlet pipe 5, and an air inlet is opened on one side of the air inlet pipe 5. The air inlet is square, and multiple sets of railings 8 are fixedly connected to the inner wall of the air inlet. The multiple sets of railings 8 are evenly distributed on the inner wall of the air inlet.

[0042] Specifically, the air inlet is set in a square shape to increase the air intake area, and gradually reduced to a circle to improve the air circulation speed and speed up the gas exhaust device. Multiple sets of railings 8 are set at the air inlet to block large debris and prevent it from entering the pipe 1 and causing blockage, thus affecting the ventilation effect.

[0043] Furthermore, another set of pipes 1 is provided with an air outlet assembly 6 at one end. The air outlet assembly 6 includes a connecting pipe 61. The connecting pipe 61 is detachably connected to the pipe 1 through a fixing assembly 7. A flexible hose 62 is fixedly connected to the connecting pipe 61, and an air outlet pipe 63 is fixedly connected to the flexible hose 62.

[0044] Specifically, the flexible hose 62 is made of aluminum foil with embedded spiral steel wire to achieve high-strength support. The flexible hose 62 makes it easy to adjust the direction of the air outlet duct 63, which facilitates installation and ensures accurate exhaust direction. At the same time, the flexible hose 62 is telescopic, which ensures that the installation length meets the installation environment in the final stage of the ventilation duct installation, avoiding the need to cut the duct 1 and facilitating installation.

[0045] Furthermore, a fixing component 7 is provided on the pipe 1, which is used to connect the air inlet pipe 5, the pipe 1 and the air outlet component 6.

[0046] Specifically, the fixing component 7 includes a first fixing ring 71 and a second fixing ring 72. The first fixing ring 71 and the second fixing ring 72 are rotatably connected. Both the first fixing ring 71 and the second fixing ring 72 are provided with slots. The slots are chamfered. The chamfer allows the first fixing ring 71 and the second fixing ring 72 to be quickly aligned during installation. At the same time, during the clamping process, the chamfer can bring the two fixing rings 73 together towards the middle, clamping the rubber gasket 3 to improve the sealing performance.

[0047] Furthermore, each end of the multiple sets of pipes 1 is fixedly connected with a fixing ring 73, and a rubber pad 3 is placed between two sets of fixing rings 73, with the fixing ring 73 and the rubber pad 3 snapped into the groove.

[0048] Specifically, the inner ring 2 connects the two pipes 1 on both sides, so that no calibration is required when splicing the pipes 1. The inner ring 2 can set the two sets of pipes 1 concentrically. At the same time, the rubber gasket 3 is placed between the two sets of pipes 1 to make the connection of the two sets of pipes 1 more airtight and prevent leakage during exhaust.

[0049] Furthermore, the first fixing ring 71 has a connecting groove, and a fixing screw 74 is rotatably connected in the connecting groove. A fixing seat 75 is threaded onto the fixing screw 74, and a knob 76 is fixedly connected to the fixing seat 75. The second fixing ring 72 has a fixing groove, and the fixing seat 75 is snapped into the fixing groove.

[0050] Specifically, by snapping the first fixing ring 71 and the second fixing ring 72 onto the fixing ring 73, and then rotating the fixing screw 74 to move the fixing seat 75 into the fixing groove of the second fixing ring 72, and then rotating the knob 76 to rotate the fixing seat 75, the fixing seat 75 locks the second fixing ring 72 in the threaded engagement with the fixing screw 74. The fixing component 7 allows for quick splicing and disassembly of the pipe 1, making the installation of the ventilation pipe quick and simple. When a single pipe 1 is damaged, it can also be quickly replaced, reducing downtime and improving emission efficiency.

[0051] Furthermore, a fixing frame 9 is fixedly connected to the outer wall of the pipe 1, and a hanging ring 10 is fixedly connected to the fixing frame 9. The hanging ring 10 is used to suspend the ventilation pipe on the device.

[0052] When it is observed through the observation window 41 that there is debris accumulation inside the pipe 1 in the above-mentioned industrial exhaust ventilation pipe, the ventilation system is turned off. By turning the knob 45, the fixing pin 43 is no longer pushed. At this time, the fixing pin 43 will retract into the groove due to the rebound force of the spring 44, so that the fixing pin 43 is disengaged from the slot of the observation window 41. Thus, the fixing pin 43 no longer fixes the observation window 41. At this time, the observation window 41 can be turned to open it, and then the pipe 1 can be cleaned to remove the debris. At the same time, the box door 48 can be disassembled to allow the debris to be discharged from the collection box 47, making cleaning more convenient. After cleaning, the box door 48 and the observation window 41 can be fixed again to form a seal.

[0053] This utility model involves fastening the first fixing ring 71 and the second fixing ring 72 onto the fixing ring 73, then rotating the fixing screw 74 to move the fixing seat 75 into the fixing groove of the second fixing ring 72, and then rotating the knob 76 to rotate the fixing seat 75. This allows the fixing seat 75 to lock the second fixing ring 72 in the threaded engagement with the fixing screw 74. The fixing component 7 allows for quick splicing and disassembly of the pipe 1, making the installation of the ventilation pipe quick and simple. It also allows for quick replacement of a damaged single pipe 1, reducing downtime and improving emission efficiency.
