Description

Technical Field

[0001] The utility model relates to a suspension blower accessory, in particular to a venting box matched with the suspension blower which is beneficial to reducing noise. Background Art

[0002] During the startup process of the air suspension blower, it is necessary to perform venting and exhaust operations to facilitate the normal startup of the equipment. During the venting process, it generates huge noise. In order to solve the problem during the venting process, the air suspension blower has a built-in venting box inside to reduce noise. However, the existing venting box is a single cube structure with weak noise reduction effect. Moreover, during long-term operation, a large amount of pollutants will accumulate on the inner wall of the existing venting box. To remove the pollutants, the existing solution is to disassemble the venting box for regular maintenance to ensure the normal operation of the venting box function and to ensure its service life, which greatly increases the maintenance difficulty of maintenance personnel and also increases the operating costs of the enterprise.

[0003] Therefore, there is an urgent need for a new type of venting box for air suspension blowers, which can effectively reduce the operating noise during the equipment startup and venting operation, and can quickly perform light self-cleaning, extend the maintenance cycle of the equipment, reduce the maintenance frequency of maintenance personnel, and reduce the operating costs of the enterprise. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the utility model provides a venting box that is conducive to reducing noise, which can effectively reduce the operating noise during the equipment startup venting operation, and can quickly perform light self-cleaning, thereby extending the maintenance cycle of the equipment, reducing the maintenance frequency of maintenance personnel, and reducing the operating costs of the enterprise.

[0005] The utility model adopts the following technical solutions:

[0006] A venting box that is beneficial to reducing noise, includes a bellows main body in a box structure, the bellows main body includes a main frame in a hollow rectangular structure and a partition plate arranged in a vertical direction inside the main frame, the interior of the bellows main body is divided into an air inlet space, an air exhaust space and a path air duct connecting the air inlet space and the air exhaust space and separated by the partition plate; an air inlet pipe connected to the air inlet space is provided at the bottom of the bellows main body, and an exhaust pipe connected to the exhaust space is provided at the top of the bellows main body; sound-absorbing panels are provided on the sides of the air inlet space, the exhaust space and the path air duct, and the sound-absorbing panels, the main frame and the partition plate form a sound-absorbing cavity.

[0007] In order to reduce the maintenance difficulty of maintenance personnel and remove pollutants attached to the silencer plate in a timely and effective manner, the device is connected to the outside of the bellows body with a recoil mechanism; the air inlet pipe and the exhaust pipe are both three-way pipes, and the recoil mechanism includes a three-way reversing valve fixed on the air inlet pipe and the exhaust pipe, and a recoil pipe network connected to the air inlet pipe and connected to the silencer cavity. The air inlet pipe and the exhaust pipe are both one-in and two-out structures, the A output end of the air inlet pipe is connected to the air inlet space, and the B output end of the air inlet pipe is connected to the recoil pipe network; the input end of the exhaust pipe is connected to the exhaust space, the A output end of the exhaust pipe is connected to the external air-using equipment, and the B output end of the exhaust pipe is connected to the dust bag. By connecting to the external dust bag, the fallen pollutants are concentrated in the dust bag, which is convenient for maintenance personnel to carry out unified and centralized treatment and reduce environmental pollution.

[0008] In order to effectively reduce the noise generated during the emptying operation of the suspension blower, the wind body enters the exhaust space along the air inlet space and the path air duct, extending the contact between the wind body and the sound insulation board. The path air duct in the device has a U-shaped structure.

[0009] Preferably, in order to further reduce the contrast produced by the venting operation, the length of the main frame and the partition plate in the width direction is 1:0.95 to 1:0.85.

[0010] At the same time, in order to improve the removal effect of pollutants attached to the silencer plate and make the silencer plates in various parts evenly obtain the effect of wind backwashing, the recoil pipe network layout is designed. The recoil pipe network includes a main guide pipe connected to the air inlet pipe, a secondary guide pipe connected to the main guide pipe and in a square structure sleeved on the outside of the bellows body, and a connecting pipe used to connect the secondary guide pipe with the silencer cavity.

[0011] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages: 1. When the suspended blower is performing the venting operation, the wind body enters the air inlet space through the air inlet pipe, hits the silencer plate in the air inlet space to reduce the noise, and enters the exhaust space along the path duct. In the process of flowing through, the sound generated is constantly reflected between the silencer plates, which is further reduced, thereby achieving the effect of effectively reducing the noise; 2. During the long-term operation, a large amount of pollutants are attached to the silencer plate. By regularly starting the recoil mechanism, the pollutants attached to the silencer plate can fall off under the action of the wind body, and are discharged into the dust collecting bag along with the wind body for unified collection, which is convenient for maintenance personnel to handle. The operation is simple and fast, which reduces the maintenance difficulty of maintenance personnel and reduces the maintenance and operation costs of the enterprise.

[0023] In order to reduce the maintenance difficulty of the maintenance personnel and timely and effectively remove the pollutants attached to the muffler plate 7, the device is connected to the outside of the bellows body 1 with a recoil mechanism 9; the air inlet pipe 5 and the exhaust pipe 6 are both three-way pipes, and the recoil mechanism 9 includes a three-way reversing valve 91 fixed on the air inlet pipe 5 and the exhaust pipe 6, and a recoil pipe network 92 connected to the air inlet pipe 5 and connected to the muffler cavity 8.
