Description

Technical Field

[0001] The utility model relates to the field of workshop dust removal, and in particular provides a pipeline between a bag dust collector and an external induced draft fan. Background Art

[0002] In the existing powder workshop, the bag dust collector is connected to an external induced draft fan. The induced draft fan is set outside the workshop and is introduced into the workshop through a metal pipe passing through the outer wall of the workshop and connected to the bag dust collector. Since the metal pipe passes through the outer wall, the pipe and the wall resonate during operation, so the noise in the workshop is very loud, which causes trouble to the company's staff. Therefore, the pipe between the bag dust collector and the external induced draft fan is improved. Summary of the Invention

[0003] The utility model aims to provide a pipeline between a bag dust collector and an external induced draft fan which can reduce noise pollution.

[0004] The technical solution of the utility model is:

[0005] A pipe between a bag dust collector and an external induced draft fan, comprising several sections of rigid pipe and at least one flexible pipe for connecting the rigid pipes in series and sealing them. Specifically, two rigid pipes are inserted into the flexible pipe at either end, preventing gas from flowing into the atmosphere from the connection between the rigid pipes and the flexible pipe. After the series connection, the rigid pipes at the head and tail ends are connected to the air outlet of the bag dust collector and the air inlet of the induced draft fan, respectively. The flexible pipe is disposed between a wall and the induced draft fan at a distance of 50 cm or less from the wall, thereby reducing noise caused by resonance between the rigid pipe and the wall.

[0006] Preferably, the distance between the wall and the hose is 30 cm;

[0007] Furthermore, the hose is detachably connected to the hard tubes at both ends thereof, and the detachable connection method includes that the two ends of the hose are sleeved on the outer walls of the hard tubes at both sides and connected by releasable clamps or snap clamps or releasable cable ties, or the two ends of the hose are sleeved on the outer walls of the hard tubes at both sides and connected by cable ties or clamps;

[0008] Wherein, the clamp and the hoop are made of metal, and the cable tie is made of plastic;

[0009] The hard pipe is a metal pipe or a hard plastic pipe, that is, a pipe that does not deform under normal circumstances when lifted or bent, and can be a steel pipe or a plastic pipe;

[0010] The hose is a tube that does not make sharp or small sounds after impact, including a silicone hose, a rubber hose, or a plastic hose, preferably a silicone hose;

[0011] The structure of the hose includes a straight hose, a telescopic hose or a bellows, preferably a telescopic hose;

[0012] Furthermore, the distance between the two rigid tubes in the hose is between 2 cm and 50 cm, ensuring that the two rigid tubes do not collide with each other during operation to increase noise pollution;

[0013] The hard pipe between the wall and the bag dust collector is coated with a sound insulation layer at the contact point with other hard parts or is also cut and connected by a hose. The hard parts include steel plates, equipment, steel pipes, etc. The sound insulation layer includes a sponge layer and / or a nylon layer and / or a cloth layer and / or other layers;

[0014] The advantages and positive effects of the utility model are:

[0015] This application connects hard pipes with hard pipes through a hose. The hose has good elasticity and flexibility, can absorb impact and vibration in the pipeline system, and reduce the resonance of the pipeline. It not only helps to protect the hard pipe, but also reduces noise and mechanical wear caused by vibration. The hose can expand and contract and deform within a certain range to adapt to the movement and deformation of the hard pipe, reduce stress concentration in the pipeline system, thereby further reducing resonance and reducing noise in the workshop.

[0016] The hose is detachably connected to the hard pipes at both ends, so it is easy to replace the hose, clamp, clamp or tie when it is damaged; when using a telescopic hose or corrugated tube in conjunction with a clamp or clamp, the hose has a long service life due to its elasticity, and the clamp has an even longer service life due to its metal material. After the two ends of the hose are sleeved on the outer walls of the hard pipes on both sides, the clamp is used to further seal the connection, so the sealing is better.

[0017] The hard pipes between the wall and the bag dust collector are covered with sound insulation layers or are cut and connected by hoses at the contact points with other hard parts, thus further reducing the noise pollution problem in the workshop. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example 1:

[0024] A pipeline structure between a bag dust collector and an external induced draft fan includes two sections of hard pipes 3 and a hose 4 for connecting the hard pipes 3 and the hard pipes 3 in series and sealing them in sequence, that is, the two hard pipes 3 are respectively inserted into the hose 4 from both ends of the hose 4 and the gas cannot flow into the atmosphere from the connection between the hard pipes 3 and the hose 4. After the series connection, the hard pipes 3 at the head and tail ends are respectively connected to the air outlet of the bag dust collector 1 and the air outlet of the induced draft fan 2, and the hose 4 is arranged between the wall 6 and the induced draft fan 2 and the distance from the wall 6 is 30 cm.

[0025] like Figure 1 and Figure 2 The figure shows a bag-type dust collector 1, one of the hard tubes 3 connected to the bag-type dust collector 1, a hose 4 connected to the hard tube 3 after passing through the wall, another hard tube 3 connected to the hose 4, and an induced draft fan 2 connected to the hard tube 3. The two ends of the elastic telescopic hose 4 made of silicone material are respectively sleeved on the outer walls of the hard tube 3 on both sides and are sealed and connected through a releasable clamp 5. The hose 4 has good elasticity and flexibility, can absorb impact and vibration in the pipeline system, and reduce the resonance of the pipeline, which not only helps to protect the hard tube, but also reduces noise and mechanical wear caused by vibration, and the hose 4 can expand and contract and deform within a certain range to adapt to the movement and deformation of the hard tube 3, reduce stress concentration in the pipeline system, and further reduce resonance. At present, the noise level in our company's workshop is low, thus reducing the problem of noise pollution.

[0026] Example 2:

[0027] A pipe structure between a bag dust collector and an external induced draft fan, such as Figure 1 and Figure 2 The figure shows a bag dust collector 1, one of the hard pipes 3 connected to the bag dust collector 1, a hose 4 connected to the hard pipe 3 after passing through the wall, another hard pipe 3 connected to the hose 4, and an induced draft fan 2 connected to the hard pipe 3. The two ends of the straight hose 4 made of silicone material are respectively sleeved on the outer walls of the hard pipe 3 on both sides and then sealed and fixed by a clamp 5, thereby reducing the noise pollution problem.

[0028] Example 3:

[0029] A pipe structure between a bag dust collector and an external induced draft fan, such as Figure 1 and Figure 2The figure shows a bag dust collector 1, one of the hard pipes 3 connected to the bag dust collector 1, a hose 4 connected to the hard pipe 3 after passing through the wall, another hard pipe 3 connected to the hose 4, and an induced draft fan 2 connected to the hard pipe 3. The two ends of the hose 4 are elastically telescopic through plastic material and are respectively sleeved on the outer walls of the hard pipe 3 on both sides and then sealed and connected through releasable clamps 5. The elastic telescopic hose 4 made of plastic material is similar to a water pressurizer on a bucket. Through this structure, the noise pollution problem is reduced.

[0030] Example 4:

[0031] A pipe structure between a bag dust collector and an external induced draft fan, such as Figure 1 and Figure 2 The figure shows a bag dust collector 1, one of the hard pipes 3 connected to the bag dust collector 1, a hose 4 connected to the hard pipe 3 after passing through the wall, another hard pipe 3 connected to the hose 4, and an induced draft fan 2 connected to the hard pipe 3. The two ends of the elastic telescopic hose 4 made of silicone material are respectively sleeved on the outer walls of the hard pipe 3 on both sides and are sealed by releasable clamps 5. The contact between the hard pipe 3 and the equipment and steel pipe between the wall 6 and the bag dust collector is covered with a sound insulation layer, which is a sponge layer. Since the hose 4 has good elasticity and flexibility, it can absorb impact and vibration in the pipeline system and reduce the resonance of the pipeline, which not only helps to protect the hard pipe 3, but also reduces noise and mechanical wear caused by vibration. The hose 4 can expand and contract and deform within a certain range to adapt to the movement and deformation of the hard pipe 3, reduce stress concentration in the pipeline system, and further reduce resonance. At present, the noise in our company's workshop is low, thus reducing noise pollution problems.

[0032] Through this application, the noise pollution problem in the workshop is significantly improved.
