Technical Field

[0001] This utility model belongs to the technical field of boiler auxiliary equipment, specifically a boiler silencer that is easy to disassemble and clean. Background Technology

[0002] Boilers generate a significant amount of noise during operation, which not only pollutes the surrounding environment but also affects the health of workers. To reduce boiler noise, silencers are typically installed on the boiler's exhaust pipes.

[0003] Currently, most existing boiler silencers are integral structures with a non-removable, one-piece molded outer shell. The internal silencing components are also fixedly connected to the outer shell. After long-term use, a large amount of dust, dirt, and other impurities will accumulate inside the silencer, which will affect the silencing effect. Furthermore, disassembling the silencer from the boiler body is quite complicated, which is not only time-consuming and laborious but also affects the normal operation of the boiler. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an easy-to-disassemble and clean boiler silencer, which effectively solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easily disassembled and cleanable boiler silencer, comprising a furnace body, a connecting pipe fixedly connected to one side of the furnace body, a silencer outer cylinder provided on one side of the connecting pipe, a silencer inner cylinder provided inside the silencer outer cylinder, a clamping mechanism provided on one side of the silencer outer cylinder, and a limiting mechanism provided on the inner wall of the silencer outer cylinder. The clamping mechanism includes an annular hollow seat fixedly installed on one side of the silencing outer cylinder. Inside the annular hollow seat, four sets of vertical rods arranged in an annular array are fixedly installed. A movable block is sleeved on the outside of the vertical rod. A first spring is fixedly connected to one side of the movable block. One side of the first spring is fixedly connected to the annular hollow seat. The first spring is sleeved on the outside of the limiting rod. A support rod is fixedly connected to one end of the movable block. A limiting rod is fixedly connected to one side of the movable block.

[0006] Preferably, a first annular plate is rotatably connected to one side of the annular hollow seat, a push rod is fixedly installed on one side of the first annular plate, one side of the push rod passes through the annular hollow seat, and four sets of arc-shaped holes are opened through one side of the first annular plate, with the support rod located in the arc-shaped holes.

[0007] Preferably, the limiting mechanism includes a second annular plate fixedly installed on the inner wall of the sound-absorbing outer cylinder, a telescopic rod symmetrically rotatably connected to one side of the second annular plate, a connecting rod fixedly connected to one side of the telescopic rod, and a positioning rod fixedly connected to one side of the connecting rod.

[0008] Preferably, a second spring is movably sleeved on the outside of the telescopic rod, one side of the second spring is fixedly connected to one side of the second annular plate, and the side of the second spring away from the second annular plate is fixedly connected to one side of the connecting rod.

[0009] Preferably, a third annular plate is fixedly connected to one side of the silencing inner cylinder, one side of the positioning rod extends into the interior of the third annular plate, a slot is opened on the outer side of the connecting pipe, and the limiting rod is inserted into the slot.

[0010] Preferably, support legs are fixedly installed at the four corners of the bottom of the furnace body, and foot pads are fixedly installed at the bottom of the support legs.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model allows the silencing device to be quickly removed from the furnace body by pushing the push rod to one side. The push rod drives the first annular plate to rotate. The annular plate, through the cooperation of the arc-shaped hole and the support rod, will drive the moving blocks to move away from each other. At the same time, the first spring is compressed, and the moving blocks drive the limiting rod to move away from each other, so that the limiting rod moves away from the slot. Then the annular hollow seat is moved to one side. The operation is simple and convenient, without the need for a complicated disassembly process. 2. This new type of device moves the connecting rod to one side by pulling it, which in turn moves the positioning rod. At the same time, it stretches the telescopic rod and the second spring, causing the positioning rod to move away from the third annular plate. Then, the connecting rod is rotated, and the third annular plate is moved. The third annular plate causes the inner and outer silencer cylinders to separate. The silencer can be disassembled manually, which greatly improves the convenience of disassembly and saves time and labor costs. Attached Figure Description

The clamping mechanism 5 includes an annular hollow seat 501 fixedly installed on one side of the silencing outer cylinder 3. Four sets of vertical rods 502 arranged in annular array are fixedly installed inside the annular hollow seat 501. A movable block 503 is sleeved on the outside of the vertical rods 502. A first spring 504 is fixedly connected to one side of the movable block 503. One side of the first spring 504 is fixedly connected to the annular hollow seat 501. The first spring 504 is sleeved on the outside of the vertical rods 502. A support rod 506 is fixedly connected to one end of the movable block 503. A limit rod 505 is fixedly connected to one side of the movable block 503.

[0016] A first annular plate 509 is rotatably connected to one side of the annular hollow seat 501. A push rod 508 is fixedly installed on one side of the first annular plate 509. One side of the push rod 508 passes through the annular hollow seat 501. Four sets of arc-shaped holes 507 are opened through one side of the first annular plate 509. A support rod 506 is located in the arc-shaped holes 507. The limiting mechanism 8 includes a second annular plate 801 fixedly installed on the inner wall of the silencing outer cylinder 3. A telescopic rod 802 is symmetrically rotatably connected to one side of the second annular plate 801. A connecting rod 803 is fixedly connected to one side of the telescopic rod 802. A positioning rod 805 is fixedly connected to one side of the connecting rod 803.

[0017] A push rod 508 is fixedly installed on one side of the first annular plate 509. One side of the push rod 508 passes through the annular hollow seat 501 and extends to the outside. This structure allows the operator to drive the first annular plate 509 to rotate by pushing the push rod 508 outside the annular hollow seat 501.

[0018] The telescopic rod 802 is externally fitted with a second spring 804. One side of the second spring 804 is fixedly connected to one side of the second annular plate 801. The side of the second spring 804 away from the second annular plate 801 is fixedly connected to one side of the connecting rod 803. One side of the silencing inner cylinder 4 is fixedly connected to a third annular plate 806. One side of the positioning rod 805 extends into the interior of the third annular plate 806.

[0019] Support legs 6 are fixedly installed at the four corners of the bottom of the furnace body 1. The support legs 6 provide a stable support base for the furnace body 1, so that the furnace body 1 can be placed stably. Foot pads 7 are fixedly installed at the bottom of the support legs 6. The foot pads 7 can increase the friction between the support legs 6 and the placement surface, further improving the stability of the furnace body 1. In addition, the foot pads 7 can also play a certain role in cushioning and reducing the noise generated by the furnace body 1 when it is working.

[0020] Working principle: In use, by pushing the push rod 508 to one side, the push rod 508 drives the first annular plate 509 to rotate. The first annular plate 509, through the cooperation of the arc hole 507 and the support rod 506, will drive the moving block 503 to move away from each other. At the same time, the first spring 504 is compressed. The moving block 503 drives the limiting rod 505 to move away from each other, so that the limiting rod 505 is away from the slot 9. Then, the annular hollow seat 501 is moved to one side, which can quickly remove the silencer from the furnace body 1. By pulling the connecting rod 803 to one side, the connecting rod 803 drives the positioning rod 805 to move. At the same time, the telescopic rod 802 and the second spring 804 are stretched, so that the positioning rod 805 is away from the third annular plate 806. Then, the connecting rod 803 is rotated, and the third annular plate 806 is moved again. The third annular plate 806 drives the silencer inner cylinder 3 to separate from the silencer outer cylinder 4. The silencer can be disassembled by manual operation.
