Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a dust cleaning device for a bag dust collector and the bag dust collector. Background Art

[0002] The bag dust collector is a dry dust filtering device, which is suitable for collecting fine, dry, non-fibrous dust. The bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-laden gas. When the dust-laden gas enters the bag dust collector, the large particles and high specific gravity dust settle due to gravity and fall into the ash hopper. The gas containing finer dust is retained when passing through the bag, so that the gas is purified.

[0003] After long-term use, bag filters need to be cleaned. Common bag cleaning methods include gas cleaning or mechanical cleaning. Gas cleaning involves using a blower to blow air in the opposite direction of the bag, blowing away dust with wind in the opposite direction of the gas filtration. However, dust that has been attached for a long time has a strong adhesion to the bag, making gas cleaning less effective. Mechanical cleaning involves shaking off dust from the bag through vibration. Currently, mechanical cleaning typically involves installing a vibrator on each bag, which drives the corresponding bag to vibrate. When there are a large number of bags, more vibrators are required, increasing equipment costs. In addition, the vibrator can easily cause wear on the bag when driving the bag to vibrate, reducing the bag's service life. Utility Model Content

If the specific posture changes, the directional indication will also change accordingly.

[0027] After long-term use, bag filters need to be cleaned. Common bag cleaning methods include gas cleaning or mechanical cleaning. Gas cleaning involves using a blower to blow air in the opposite direction of the bag, blowing away dust with wind in the opposite direction of the gas filtration. However, dust that has been attached for a long time has a strong adhesion to the bag, making gas cleaning less effective. Mechanical cleaning involves shaking off dust from the bag through vibration. Currently, mechanical cleaning typically involves installing a vibrator on each bag, which drives the corresponding bag to vibrate. When there are a large number of bags, more vibrators are required, increasing equipment costs. In addition, the vibrator can easily cause wear on the bag when driving the bag to vibrate, reducing the bag's service life.

[0028] The present invention proposes a dust cleaning device for a bag dust collector, which is arranged in a dust removal chamber of the bag dust collector, and the dust cleaning device includes a hanging plate 10 and a vibrating motor 20. The hanging plate 10 is horizontally arranged, and the hanging plate 10 is movably connected to the inner wall of the dust removal chamber along the transverse edge. A plurality of cloth bags 11, all of which are cylindrical, are hung on the lower surface of the hanging plate 10. The plurality of cloth bags 11 are arranged in an array in the transverse and longitudinal directions, and each cloth bag 11 extends vertically, and an air inlet 111 is formed at the lower end of each cloth bag 11; the mounting end 22 of the vibrating motor 20 is installed on the inner wall of the dust removal chamber, and the output end 21 of the vibrating motor 20 is transversely connected to the hanging plate 10, and the vibrating motor 20 is used to drive the hanging plate 10 to vibrate in the transverse direction to drive each cloth bag 11 to swing.

[0029] See also Figure 1 , Figure 1 The left and right directions in the text are horizontal. Figure 1 The front-to-back direction is the longitudinal direction. Figure 1 The up and down directions in the figure are vertical. Each bag 11 is suspended on the lower surface of the suspension plate 10, and each bag 11 extends vertically, so that the gas to be filtered enters the bag 11 from the air inlet 111 at the lower end of the bag 11, flows upward out of the dust removal chamber after being filtered by the bag 11, and the dust in the gas is retained in the bag 11. The suspension plate 10 is movably connected to the inner wall of the dust removal chamber along the left and right edges, and the output end 21 of the vibrating motor 20 is connected to the left and right edges of the suspension plate 10. The vibrating motor 20 can drive the suspension plate 10 to vibrate horizontally in the dust removal chamber. The suspension plate 10 transmits the vibration to the bags 11 suspended on its lower surface, so as to cause the bags 11 to swing, thereby shaking off the dust in the bags 11.

[0030] The dust cleaning device of the bag dust collector proposed by the present invention is a device that movably connects a hanging plate 10 to a dust removal chamber, suspends a plurality of cloth bags 11 on the lower surface of the hanging plate 10, and drives the hanging plate 10 to vibrate by a vibrating motor 20. The hanging plate 10 transmits the vibration to the plurality of cloth bags 11, causing each cloth bag 11 to swing, thereby shaking off the dust in the cloth bags 11 and achieving the purpose of dust cleaning. The lower surface of the hanging plate 10 provides a hanging surface for the cloth bags 11, which is convenient for the large-scale installation of a plurality of cloth bags 11. A single or several vibrating motors 20 can drive the plurality of cloth bags 11 to vibrate simultaneously, which can effectively reduce the cost of equipment. In addition, the vibration of the vibrating motor 20 is directly transmitted to the hanging plate 10, and each cloth bag 11 can be flexibly connected to the bottom of the hanging plate 10. The hanging plate 10 acts as a buffer for the vibration force, thereby significantly reducing the wear of the cloth bags 11 by the vibration when driving the cloth bags 11 to swing, effectively extending the service life of the cloth bags 11.

[0031] In one embodiment, there are two vibrating motors 20, and the two output ends 21 of the two vibrating motors 20 are respectively connected to the two sides of the suspension plate 10 along the horizontal direction, and the two mounting ends 22 are respectively installed on the two inner walls of the dust removal chamber along the horizontal direction; the two output ends 21 move synchronously in opposite directions to cooperate with each other to drive the suspension plate 10 to vibrate horizontally.

[0032] It can be understood that the two vibrating motors 20 are arranged opposite to each other, and the two output ends 21 are respectively connected to the left and right sides of the suspension plate 10. The vibration frequency and amplitude of the two vibrating motors 20 are the same, but the vibration directions are opposite. Through the cooperation of the two vibrating motors 20, the suspension plate 10 is jointly driven to vibrate back and forth in the horizontal direction, making the vibration of the suspension plate 10 more uniform and effective, thereby improving the cleaning efficiency.

[0033] In one embodiment, both side edges of the suspension plate 10 in the transverse direction are connected to two inner walls of the dust removal chamber in the transverse direction through a plurality of elastic members 30 .

[0034] See also Figure 2 The two side edges of the suspension plate 10 along the horizontal direction are connected to the two inner walls of the dust removal chamber along the horizontal direction through multiple elastic members 30. Each elastic member 30 provides a certain elastic connection between the suspension plate 10 and the inner wall of the dust removal chamber, allowing the suspension plate 10 to vibrate laterally under the drive of the vibration motor 20, while absorbing part of the impact force generated during the vibration process, thereby protecting the suspension plate 10 and the cloth bag 11 from damage and extending the service life of the cloth bag 11.

[0035] In one embodiment, the elastic member 30 is a spring, and a plurality of springs located on the same side of the suspension plate 10 are spaced apart in the longitudinal direction.

[0036] Furthermore, a plurality of springs are connected to each lateral edge of the suspension plate 10, each spring extends laterally, and the multiple springs located on the same side are arranged at intervals along the longitudinal direction. The multiple springs provide lateral support to the suspension plate 10, so that the suspension plate 10 can hang multiple cloth bags 11 and allow the suspension plate 10 to vibrate laterally.

[0037] In one embodiment, the suspension plate 10 , each elastic member 30 , and the output end 21 of the rapping motor 20 are all located on the same horizontal plane.

[0038] It can be understood that the suspension plate 10, the elastic member 30 and the output end 21 of the vibrating motor 20 are in the same horizontal plane, ensuring that the vibration force of the vibrating motor 20 is evenly transmitted to the suspension plate 10, so that each bag 11 can obtain uniform and sufficient vibration, thereby ensuring the cleaning effect, and helping to maintain the stability of the entire cleaning device, reducing structural displacement or deformation caused by vibration.

[0039] In one embodiment, the upper end of each cloth bag 11 is hung on the lower surface of the hanging plate 10 via a hanging chain 40 .

[0040] It is worth noting that the hanging chain 40 flexibly connects each cloth bag 11 to the lower surface of the suspension plate 10. While driving the cloth bag 11 to swing with the suspension plate 10, the hanging chain 40 can also partially buffer the vibration force caused by the vibration of the suspension plate 10, reducing the wear on the cloth bag 11 caused by vibration, thereby extending the service life of the cloth bag 11. For example, the hanging chain 40 can be an iron chain or the like as used in the prior art.

[0041] In one embodiment, the suspension plate 10 includes a support area 12 and an installation area 13, the support area 12 surrounds the installation area 13, and each bag 11 is suspended in the installation area 13. The cleaning device also includes a plurality of support columns 50, and the plurality of support columns 50 are supported at intervals in the support area 12.

[0042] It should be explained that the support area 12 is located at the edge of the suspension plate 10, and the installation area 13 is located in the middle of the suspension plate 10. The support area 12 provides a support position for the support column 50, and the installation area 13 provides a suspension position for the cloth bags 11. The support area 12 and the installation area 13 are spaced apart so that the support columns 50 and the cloth bags 11 do not interfere with each other. Multiple support columns 50 are spaced apart along the extension direction of the support area 12. The lower end of each support column 50 is supported by the bottom of the dust removal chamber, and the top end of each support column 50 is movably supported by the support area 12. The multiple support columns 50 jointly provide support for the suspension plate 10, making the suspension plate 10 more stable when suspending multiple cloth bags 11.

[0043] In one embodiment, each cloth bag 11 is provided with a plurality of inner support rings 60 spaced apart vertically.

[0044] See also Figure 3 The inner support ring 60 is used to maintain the cylindrical shape of the bag 11, facilitating the entry of the filtered gas into the bag 11 through the air inlet 111, ensuring the consistency of the filtering and cleaning effects of the bag 11. At the same time, multiple inner support rings 60 can prevent adjacent bags 11 from interfering with each other during swinging, thus preventing multiple bags 11 from becoming entangled.

[0045] In one embodiment, the suspension plate 10 is a steel grating. As will be appreciated, the steel grating has high strength and low weight, enabling it to withstand a large load of bags 11 without adding excessive weight. Furthermore, the grid structure of the steel grating facilitates the flow of filtered air out of the dust removal chamber, facilitating air circulation within the dust removal chamber.

[0046] The present invention also proposes a bag dust collector, which is applied with the above-mentioned cleaning device. The specific structure of the cleaning device refers to the above-mentioned embodiment. Since the bag dust collector adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. Among them, the cleaning device is arranged in the dust removal chamber of the bag dust collector, and the cleaning device drives the suspension plate 10 to vibrate through the vibration motor 20. The suspension plate 10 transmits the vibration to multiple bags 11, causing each bag 11 to swing, thereby achieving the purpose of cleaning the bags 11. Since only a single or several vibration motors 20 are provided, multiple bags 11 can be cleaned in large quantities, which can effectively reduce the equipment cost. In addition, the vibration effect of the vibration motor 20 is directly transmitted to the suspension plate 10, and each bag 11 can be flexibly connected to the bottom of the suspension plate 10. The suspension plate 10 has a buffering effect on the vibration force, thereby greatly reducing the wear of the bags 11 caused by the vibration when driving the bags 11 to swing, effectively extending the service life of the bags 11.

[0047] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
