Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a noise reduction device for a dust collector used in cement production. Background Art

[0002] During the cement production process, dust collectors are needed to absorb dust. The noise detected by the dust collector of a high-power motor during working hours exceeds 80 decibels. Due to the excessive noise, on-site construction workers are often reluctant to turn on the dust collector, resulting in dust all over the site. Under the existing technology, in order to reduce dust and noise, people will add a muffler to the pipe outlet of the dust collector. The muffler can reduce the noise, but in actual application, we found that along with the reduction of noise, a lot of flying dust will enter the muffler, causing the muffler to become blocked. The staff needs to frequently remove the muffler for maintenance. Since the muffler and the dust collector are fixedly connected, the installation, disassembly and maintenance of the muffler are very inconvenient, which brings great trouble to the staff.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In this embodiment, refer to Figure 1-3 A dust collector noise reduction device for cement production includes a dust collector body 1, a conveying pipe 2 is arranged at the discharge port of the dust collector body 1, a muffler body 3 is arranged on the top of the conveying pipe 2, and a rainproof shed is installed on the top of the muffler body 3.

[0022] A connection mechanism 4 is provided between the delivery pipeline 2 and the muffler body 3, and a soft connection is formed between the delivery pipeline 2 and the muffler body 3 above through the connection mechanism 4. Specific description:

[0023] The external frame structure of the muffler body 3 is placed on the connecting mechanism 4, and the muffler body 3 is placed on the connecting mechanism 4 at the bottom, forming a stable matching relationship, which can ensure that noise enters the muffler body 3, and no assembly is formed between the two, which is conducive to directly removing the muffler body 3 from the connecting mechanism 4 at a later time.

[0024] As attached Figure 2 As shown, the connection mechanism 4 includes an outer ring fixing seat 5 and an inner ring mounting seat 6, and a dust outlet 16 for the conveying pipe 2 to discharge outward is reserved at the center of the inner ring mounting seat 6.

[0025] An inner gear ring 7 is provided on the inner surface of the outer ring fixing seat 5, and a number of circumferentially distributed gears 8 are provided inside the inner ring mounting seat 6, and each gear 8 is meshed with the outer inner gear ring 7. Tooth plates 9 meshing with each corresponding gear 8 are also provided inside the inner ring mounting seat 6, and the positions of the inner gear ring 7 and the tooth plates 9 are relatively staggered and do not affect each other.

[0026] The outer ring fixing seat 5 and the inner ring mounting seat 6 are provided with a communicating slide groove 15 for the linear sliding of the tooth plate 9. The inner end of the tooth plate 9 extends into the outer ring fixing seat 5, and the upper surface of the outer ring fixing seat 5 is provided with an annular receiving groove 12. The lower end of the filter cloth net 13 provided at the bottom entrance of the muffler body 3 is embedded in the annular receiving groove 12. The inner end of the tooth plate 9 is provided with a clamping block 14 respectively; the filter cloth net 13 provided at the entrance of the muffler body 3 is embedded in the annular receiving groove 12 reserved on the connecting mechanism 4. Each clamping block 14 extends into the inner part of the outer ring fixing seat 5 respectively, and the clamping block 14 pushes the filter cloth net 13 against the groove wall of the annular receiving groove 12.

[0027] Finally, it should be supplemented that a dust cover 10 is provided on the top of the inner ring mounting seat 6, a motor 11 is provided inside the dust cover 10, and a drive shaft provided at the output end of the motor 11 is at the center of one of the gears 8 in the inner ring mounting seat 6.

[0028] When the motor 11 is started, one of the gears 8 is controlled to rotate, so that the inner gear ring 7 can rotate synchronously, and then drive all the gears 8 to rotate. Because the gears 8 are meshed with the tooth plates 9, all the tooth plates 9 will slide forward and backward. When installing the muffler body 3, it is necessary to ensure that the lower end of the filter cloth net 13 at the bottom of the muffler body 3 is completely built into the annular receiving groove 12, and then control each tooth plate 9 to extend outward, and use the clamping block 14 to push the filter cloth net 13 against the annular receiving groove 12, so that the position of the filter cloth net 13 is fixed. Under such a design, on the one hand, the filter cloth net 13 can further filter the dust, and on the other hand, it can also prevent the filter cloth net 13 from being separated due to the huge air pressure discharged in the dust collector body 1. Since a nearly closed discharge channel is formed between the conveying pipe 2 of the dust collector body 1 and the muffler body 3, the muffler body 3 can be used for noise reduction, and when the muffler body 3 is subsequently maintained, the muffler can be quickly disassembled, which provides convenience for subsequent manual operation.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
