Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology, and in particular to a self-cleaning boiler noise reduction device. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The hot water or steam produced in the boiler can directly provide the heat energy required for industrial production and people's lives. It can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. It is now widely used.

[0003] Chinese patent document CN213453588U discloses a boiler equipment silencer, including a silencer cylinder fitted onto the exhaust pipe port; a connecting component is installed at the top of the silencer cylinder; a cross-shaped symmetrically distributed fixing plate is installed on the outer periphery of the exhaust pipe port; the silencer cylinder is fastened to the fixing plate via the connecting component; a first sound-absorbing cotton is installed on the inner wall of the silencer cylinder; a sound-absorbing plate is installed in the middle of the first sound-absorbing cotton; and a second sound-absorbing cotton is installed on the sound-absorbing plate. This utility model has a simple overall structure, is easy to disassemble and assemble, and facilitates the overall replacement and maintenance of the silencer, bringing convenience to practical operation. By installing the first sound-absorbing cotton, the sound-absorbing plate, and the second sound-absorbing cotton inside the silencer cylinder, the contact surface between the emitted noise and the sound-absorbing cotton can be increased, and the sound energy is converted into heat energy and dissipated through friction in the pores, thereby improving the noise reduction effect on the boiler equipment and showing broad market prospects.

[0004] The existing technology has the following problems:

[0005] The muffler has the muffler components installed directly inside the muffler cylinder. However, in actual use, although most of the sound energy is converted into heat energy, a small portion is converted into mechanical energy. This mechanical energy causes the muffler components to vibrate, affecting the connection between the components. Utility Model Content

[0006] This invention provides a self-cleaning boiler silencing device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A self-cleaning boiler silencing device includes a mechanism cylinder, a fixing mechanism movably installed on the upper side of the mechanism cylinder, an exhaust pipe movably installed on the inner side of the fixing mechanism, a silencing mechanism movably sleeved on the inner side of the mechanism cylinder, an installation mechanism fixedly connected to the outer side of the exhaust pipe, and a plurality of ring-shaped hooks fixedly connected to the middle of the outer side of the mechanism cylinder.

[0009] The silencing mechanism includes a silencing component. Several annularly distributed springs are fixedly connected to the outer side of the silencing component near the upper and lower sides. A support platform is fixedly connected to the side of the springs away from the silencing component, and two support platforms are symmetrically distributed at the top and bottom. The outer sides of the silencing component, springs, and support platforms are movably sleeved on the inner side of the mechanism cylinder. A limit ring is fixedly connected to the inner side of the mechanism cylinder near the upper side, and the lower side of the limit ring overlaps the upper side of the upper support platform. A fixing component overlaps the lower side of the lower support platform.

[0010] Preferably, the fixing component includes a top seat, with a plurality of annularly distributed screws threaded to the outer side of the top seat near the upper side. A fixing seat is movably sleeved on the inner side wall of the top seat, and a plurality of annularly distributed insertion holes are provided on the outer side of the fixing seat. The upper side of the fixing seat is fixedly connected to the outer side of the mechanism cylinder near the bottom by a flange structure.

[0011] Preferably, several of the sockets are vertically distributed.

[0012] Preferably, a plurality of ring-shaped retaining strips are fixedly connected to the inner side of the mechanism cylinder, and the outer vertical groove of the support platform is movably sleeved on the outer side of the retaining strips.

[0013] Preferably, rubber pads are fixedly connected to the sides of the two support platforms that are far apart from each other.

[0014] Preferably, the mounting mechanism includes a movable ring, the inner side of which is movably sleeved on the outer side of the exhaust pipe. A plurality of annularly distributed suspension brackets are fixedly connected to the lower side of the movable ring.

[0015] Preferably, a torsion spring is provided between the lower side of each of the hanging rings and the outer side of the mechanism cylinder.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] 1. This utility model provides a self-cleaning boiler silencing device, which adopts the cooperation of a mechanism cylinder, silencing mechanism, silencing component, spring, support platform, limit ring, fixing component, top seat, screw, fixing seat, insertion hole and locking strip. The springs are arranged in a ring, and the side close to the silencing component moves inward, so that the vibration generated by the silencing component during silencing is greatly canceled. At the same time, the silencing component is fixed by the fixing component, so that the silencing component can be quickly disassembled and the silencing component can be easily maintained.

[0018] 2. This utility model provides a self-cleaning boiler silencing device, which uses a combination of a mechanism cylinder, a fixing mechanism, an exhaust pipe, an installation mechanism, a movable ring, a suspension frame, a hydraulic rod, and a hanging ring. The hydraulic rod drives the mechanism cylinder to move up and down, making the mechanism cylinder more stable during installation. This eliminates the instability caused by using suspension equipment to lift the mechanism cylinder. At the same time, when removing the mechanism cylinder, the hydraulic rod stabilizes the mechanism cylinder, preventing the mechanism cylinder from suddenly falling when the fixing mechanism separates from the exhaust pipe, making installation and disassembly safer.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5 As shown, a self-cleaning boiler silencing device includes a mechanism cylinder 1, a fixing mechanism 2 movably installed on the upper side of the mechanism cylinder 1, an exhaust pipe 3 movably installed on the inner side of the fixing mechanism 2, a silencing mechanism 4 movably sleeved on the inner side of the mechanism cylinder 1, an installation mechanism 5 fixedly connected to the outer side of the exhaust pipe 3, and several ring-shaped hooks 6 fixedly connected to the middle of the outer side of the mechanism cylinder 1.

[0027] The silencing mechanism 4 includes a silencing component 41. Several annularly distributed springs 42 are fixedly connected to the outer side of the silencing component 41 near the upper and lower sides. A support platform 43 is fixedly connected to the side of the springs 42 away from the silencing component 41. Two support platforms 43 are symmetrically distributed vertically. The outer sides of the silencing component 41, springs 42 and support platforms 43 are movably sleeved on the inner side of the mechanism cylinder 1. A limit ring 44 is fixedly connected to the inner side of the mechanism cylinder 1 near the upper side. The lower side of the limit ring 44 overlaps the upper side of the upper support platform 43. A fixing component 45 overlaps the lower side of the lower support platform 43.

[0028] It should be noted that the spring 42 is a shock-absorbing spring with internal damping components. Each layer of spring 42 forms a ring, and the side of the spring 42 closest to the muffler 41 moves inward. The structure of the muffler 41 is consistent with the structure of the component with the passage function in the reference case. The limiting ring 44 is used to limit the uppermost position of the support platform 43. The structure of the fixing mechanism 2 is consistent with the structure of the component with the passage function in the reference case.

[0029] like Figure 4 As shown, the fixing assembly 45 includes a top seat 451. Several annularly distributed screws 452 are threaded to the outer side of the top seat 451 near the upper side. A fixing seat 453 is movably sleeved on the inner side wall of the top seat 451. Several annularly distributed insertion holes 454 are opened on the outer side of the fixing seat 453. The upper side of the fixing seat 453 is fixedly connected to the outer side of the mechanism cylinder 1 near the bottom through a flange structure.

[0030] It should be noted that the lower side of the lower support platform 43 overlaps the inner bottom upper surface of the top seat 451, which is used to push the lower support platform 43 upward to prevent the muffler 41 and the support platform 43 from falling from the inside of the mechanism cylinder 1. The outer sides of the screws 452 are movably sleeved on the inner side of the insertion hole 454 at a position close to each other, which is used to fix the top seat 451 and the fixed seat 453.

[0031] like Figure 4 As shown, there are several vertically distributed sockets 454.

[0032] It should be noted that by inserting screws 452 into the sockets 454 of each layer, the height between the top seat 451 and the fixed seat 453 is controlled on one side, and the initial compression of the spring 42 is controlled on the other side. The number of sockets 454 in each layer is N times the number of screws 452, where N is greater than or equal to 2 and N is an integer. The height of the sockets 454 between two adjacent screws 452 is different, and the position of the highest socket 454 is slightly lower than the position of the lowest socket 454 of the adjacent upper layer, so as to improve the adjustment accuracy.

[0033] like Figure 3As shown, several ring-shaped locking strips 46 are fixedly connected to the inner side of the mechanism cylinder 1, and the outer vertical groove of the support platform 43 is movably sleeved on the outer side of the locking strips 46.

[0034] It should be noted that the locking strip 46 is used to limit the support platform 43, so that the support platform 43 and the mechanism cylinder 1 cannot rotate relative to each other.

[0035] like Figure 2 As shown, rubber pads are fixedly connected to the two support platforms 43 on the sides that are far apart from each other.

[0036] It should be noted that the rubber pad is used to prevent direct contact between the support platform 43 and the limiting ring 44, as well as between the support platform 43 and the top seat 451, so as to avoid friction caused by the wobbling of the support platform 43 due to the gap between the components.

[0037] like Figure 5 As shown, the mounting mechanism 5 includes a movable ring 51, the inner side of which is movably sleeved on the outer side of the exhaust pipe 3. Several annularly distributed suspension brackets 52 are fixedly connected to the lower side of the movable ring 51. Hanging rings 54 are movably sleeved on the inner bottom of each of the several suspension brackets 52. The lower side of the hanging rings 54 is rotatably connected to the outer side of the mechanism cylinder 1 near the upper side. Several annularly distributed hydraulic rods 53 are fixedly connected to the lower side of the movable ring 51. The lower side of the hydraulic rods 53 is fixedly connected to the outer side of the exhaust pipe 3 near the bottom.

[0038] It should be noted that the hydraulic rod 53 drives the movable ring 51 to move up and down. When the movable ring 51 moves up and down, it drives the suspension frame 52 to move up and down. When the suspension frame 52 moves up and down, it drives the hanging ring 54 to move up and down. When the hanging ring 54 moves up and down, it drives the mechanism cylinder 1 to move up and down.

[0039] like Figure 5 As shown, torsion springs are provided between the lower side of several hanging rings 54 and the outer side of the mechanism cylinder 1.

[0040] It should be noted that the torsion spring is used to drive the hanging ring 54. When the position of the mechanism cylinder 1 cannot be moved, the movable ring 51 drives the suspension frame 52 to move down, so that the hanging ring 54 disengages from the inside of the suspension frame 52, and the hanging ring 54 automatically pops out from the inside of the suspension frame 52 without manual operation.

[0041] The working principle of this utility model is as follows: First, the spring 42 is a shock-absorbing spring with a damping component inside. Each layer of springs 42 forms a ring, and the side of the springs closest to the muffler 41 moves inward. The structure of the muffler 41 is consistent with the structure of the functional component in the reference case. The limiting ring 44 is used to limit the uppermost position of the support platform 43. The lower side of the lower support platform 43 overlaps the inner bottom upper surface of the top seat 451 to push the lower support platform 43 upward, preventing the muffler 41 and the support platform 43 from falling from the inside of the mechanism cylinder 1. The outer sides of the screws 452 are movably sleeved on the inner side of the insertion hole 454 to fix the top seat 451 and the fixed seat 453. The springs 42 are arranged in a ring, and the side of the springs closest to the muffler 41 moves inward, so that the vibration generated by the muffler 41 during muffler operation is greatly canceled out. At the same time, the muffler 41 is fixed by the fixing component 45, so that the muffler 41... 41 can be quickly disassembled, facilitating maintenance of the muffler 41. Finally, the hydraulic rod 53 drives the movable ring 51 to move up and down. When the movable ring 51 moves up and down, it drives the suspension frame 52 to move up and down. When the suspension frame 52 moves up and down, it drives the hanging ring 54 to move up and down. When the hanging ring 54 moves up and down, it drives the mechanism cylinder 1 to move up and down. The torsion spring is used to drive the hanging ring 54. When the position of the mechanism cylinder 1 cannot be moved, the movable ring 51 drives the suspension frame 52 to move down, causing the hanging ring 54 to disengage from the inside of the suspension frame 52. This allows the hanging ring 54 to automatically pop out from the inside of the suspension frame 52 without manual operation. The hydraulic rod 53 drives the mechanism cylinder 1 to move up and down, making the mechanism cylinder 1 more stable during installation. This eliminates the problem of instability during installation caused by using suspension equipment to lift the mechanism cylinder 1. At the same time, when removing the mechanism cylinder 1, the hydraulic rod 53 stabilizes the mechanism cylinder 1, preventing the mechanism cylinder 1 from suddenly falling when the fixing mechanism 2 separates from the exhaust pipe 3. This makes installation and disassembly safer.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
