A dust removal unit of a bag-type dust collector and a bag-type dust collector

Abstract

This utility model belongs to the field of environmental protection equipment technology, and provides a bag filter dust collector unit and a bag filter dust collector. The bag filter dust collector unit includes a tube sheet, filter bags, multiple impact plates, a rapping assembly, and a drive assembly. When dust removal is required, the drive assembly drives the rapping shaft to rotate, which in turn drives the rapping plates and rapping hammers to rotate. The rapping hammers first abut against one of the impact plates. As the rapping shaft continues to rotate, the rapping plates are subjected to force and bend, accumulating elastic potential energy. This continues until the plates detach from the impact plates and move to the next impact plate. The rapping hammers strike the impact plate, and the vibration received by the impact plate is transmitted to the bag body through the frame, causing the bag body to vibrate, thereby achieving the dust removal effect. Throughout the process, the rapping hammers do not contact the bag body, therefore, the bag body will not be damaged. The bag filter dust collector provided by this utility model includes the above-mentioned bag filter dust collector unit.

Description

Technical Field

[0001] This utility model belongs to the field of environmental protection equipment technology, specifically relating to a dust removal unit and a bag filter dust collector. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle down due to gravity and fall into the ash hopper. The gas containing finer dust particles is purified as it passes through the filter media, with the dust being trapped.

[0003] Generally, the dust removal efficiency of new filter bags is not high enough. After a period of use, due to effects such as sieving, collision, retention, diffusion, and electrostatics, a layer of dust accumulates on the surface of the filter bag. This layer of dust is called the primary layer. In subsequent operation, the primary layer becomes the main filtration layer of the filter bag. Relying on the primary layer, even filter bags with larger mesh sizes can achieve high filtration efficiency. As dust accumulates on the surface of the filter bag, the efficiency and resistance of the dust collector increase accordingly. When the pressure difference across the filter bag is large, some fine dust particles already attached to the filter bag will be squeezed through, causing the dust collector efficiency to decrease. In addition, excessively high resistance of the dust collector will significantly reduce the airflow of the dust collection system. Therefore, once the resistance of the dust collector reaches a certain value, it is necessary to clean the dust in a timely manner.

[0004] Existing baghouse dust collectors typically use pulse jet cleaning for dust removal. However, as the equipment becomes larger and the bags become longer, the effective length of the pulse jet is limited, resulting in poor dust removal in the lower half of the bag and affecting the length arrangement of the bags.

[0005] To address the aforementioned issues, some baghouse dust collectors employ a vibrating method for cleaning the filter bags. This involves using multiple vibrators spaced along the length of the filter bag to vibrate it, transmitting the vibration to the entire bag and effectively resolving the problem of poor cleaning in the lower half of the filter bag. However, to ensure cleaning efficiency, the vibrators typically directly strike the filter bag body, which can easily damage the bag body after prolonged operation. Utility Model Content

[0027] Please refer to the following: Figure 1 to Figure 6 The dust removal unit of the bag filter provided by this utility model will now be described. The dust removal unit of the bag filter includes a tube sheet 10, filter bags, multiple impact plates 30, a rapping assembly, and a drive assembly. The tube sheet 10 has mounting holes. The filter bags include a bag body 21 and a frame 22. The bag body 21 passes through the mounting holes and connects to the tube sheet 10. The frame 22 is inserted inside the bag body 21 and is fixedly connected to or abuts against the side wall of the bag body 21. Multiple impact plates 30 are spaced apart inside the frame 22 and fixedly connected to it. The rapping assembly includes a rapping shaft 41 and rapping elements. The rapping shaft 41 is located inside the bag body 21 and is coaxially arranged with it. The rapping elements include a rapping plate 42 and a rapping hammer 43. The rapping plate 42 is a flexible plate, with one end fixedly connected to the rapping shaft 41 and the other end fixedly connected to the rapping hammer 43. The rapping hammer 43 is used to strike the impact plates 30. The drive assembly's power output end is connected to the rapping shaft 41 to drive the rapping shaft 41 to rotate.

[0028] It should be noted that the vibration plate 42 is made of steel, high-density polyethylene, polypropylene, or other plates with good toughness. The width of the vibration plate 42 is parallel to the axis of the vibration shaft 41. This provides good support to prevent the vibration hammer 43 from sagging, and also better accumulates elastic potential energy to ensure vibration force. The vibration hammer 43 is made of metal, high-temperature resistant plastic, rubber, or other hammers with good impact resistance.

[0029] The beneficial effects of the bag filter dust removal unit provided in this embodiment of the present invention are as follows: Compared with the prior art, the bag filter dust removal unit provided in this embodiment of the present invention has a filter bag fixedly connected to the tube sheet 10, a frame 22 provided inside the bag body 21, and the frame 22 is fixedly connected to or abutted against the side wall of the bag body 21 to better transmit the vibration of the frame 22 to the bag body 21. Multiple impact plates 30 are fixedly arranged on the frame 22. When dust removal is required, the vibrating shaft 41 is driven to rotate by the driving component, which in turn drives the vibrating plate 42 and the vibrating hammer 43 to rotate. The vibrating hammer 43 first abuts against one of the impact plates 30, and the vibrating shaft 41 rotates. 1. As the vibration plate 42 continues to rotate, it is subjected to force and bends, accumulating elastic potential energy. During this process, the vibration hammer 43 gradually moves along the surface of the impact plate 30 towards the edge as the vibration plate 42 bends, until it detaches from the impact plate 30 and moves to the next impact plate 30. During this process, the vibration plate 42 releases elastic potential energy, which is converted into the kinetic energy of the vibration hammer 43, ensuring the force of the vibration hammer 43 striking the impact plate 30. The vibration received by the impact plate 30 is transmitted to the bag body 21 through the frame 22, causing the bag body 21 to vibrate, thereby achieving the dust removal effect. Throughout the process, the vibration hammer 43 does not contact the bag body 21, so it will not damage the bag body 21.

[0030] like Figure 5 As shown, in a specific embodiment of the dust removal unit of the bag filter provided in this utility model, the frame 22 includes an upper ring 221, a lower ring 222 and a plurality of support rods 223. The upper ring 221 is located at the top of the bag body 21; the lower ring 222 is located at the bottom of the bag body 21 and is coaxially arranged with the upper ring 221; the plurality of support rods 223 are arranged at intervals between the upper ring 221 and the lower ring 222 along the circumference of the upper ring 221. One end of the support rod 223 is connected to the upper ring 221 and the other end is connected to the lower ring 222; wherein the support rods 223 are fixedly connected to or abut against the bag body 21, and the impact plate 30 is fixedly connected to the support rods 223.

[0031] It should be noted that the support rod 223 can be fixedly connected to the bag body 21 by means of sewing, gluing, or wrapping around the side wall of the bag body 21. It can also be used to support the bag body 21 tightly, thereby better transmitting vibration.

[0032] like Figure 5 As shown, in a specific embodiment of the dust removal unit of the bag filter provided in this utility model, the upper ring 221 is fixedly connected to the tube sheet 10, and the support rod 223 is in the shape of an outwardly protruding arc, which abuts against the bag body 21.

[0033] Specifically, the support rod 223 is a thin rod with good toughness, such as steel strip, high-density polyethylene strip, or polypropylene strip, which can bend outward to a certain extent.

[0034] Before installation, the total length of the frame 22 is greater than the length of the bag body 21. During installation, first fix the bag body 21 to the flower plate 10, then insert the frame 22 into the bag body 21 so that the lower ring 222 is pressed against the bottom of the bag body 21. At this time, the upper ring 221 protrudes from the top of the bag body 21. Then, press down on the upper ring 221 to make the support rod 223 bend outward and press against the bag body 21. Then, fix the upper ring 221 to the flower plate 10 so that the support rod 223 is kept pressed against the bag body 21.

[0035] Multiple screws are fixed on the upper side of the tube sheet 10. The screws pass through the upper ring 221 and are screwed to the nut, thus fixing the upper ring 221 to the tube sheet 10.

[0036] Furthermore, such as Figure 5 As shown, in a specific embodiment of the dust removal unit of the bag filter provided in this utility model, each support rod 223 is provided with multiple impact plates 30 at intervals from top to bottom, and the vibrating element vibrates all the impact plates 30 in sequence or simultaneously to better vibrate the entire bag body 21 and ensure the dust removal effect.

[0037] like Figure 5 and Figure 6 As shown, in a specific embodiment of the dust removal unit of the bag filter provided in this utility model, the rapping assembly includes multiple rapping elements, and each rapping element corresponds to a strike plate 30.

[0038] It should be noted that multiple rapping components correspond one-to-one with all the impact plates 30, so that as the rapping shaft 41 rotates, all the impact plates 30 are rapped simultaneously to ensure rapping force and thus effectively ensure the dust removal effect.

[0039] like Figure 1 and Figure 5 As shown, in a specific embodiment of the dust removal unit of the bag filter provided in this utility model, the upper end of the vibrating shaft 41 is connected to the power output end of the drive component, and the lower end is rotatably connected to the lower ring 222. The lower ring 222 radially limits the vibrating shaft 41 so as to better transmit the vibration to the frame 22 and then to the bag body 21.

[0040] like Figure 1 and Figure 2 As shown, in a specific embodiment of the dust removal unit of the bag filter provided in this utility model, it also includes a mounting frame 50. The mounting frame 50 is disposed on the upper side of the tube sheet 10 and connected to the tube sheet 10. The vibrating shaft 41 is rotatably connected to the mounting frame 50 and has the freedom to rotate around its own axis, so as to better fix the vibrating shaft 41 and thus better transmit the vibration to the frame 22.

[0041] like Figure 2 and Figure 6As shown, in a specific embodiment of the dust removal unit of the bag filter provided in this utility model, the rapping assembly further includes a drive shaft 44, a spring 45, and a connecting frame 46. The drive shaft 44 is coaxially arranged with the rapping shaft 41 and spaced apart on the upper side of the rapping shaft 41, and is rotatably connected to the mounting frame 50. The inner ring of the spring 45 is fixedly connected to the rapping shaft 41. One end of the connecting frame 46 is fixedly connected to the drive shaft 44, and the other end is fixedly connected to the outer ring of the spring 45.

[0042] It should be noted that during operation, the spring 45 and the vibrating plate 42 work together to accumulate and release elastic potential energy, which can effectively increase the amount of accumulated elastic potential energy. In turn, during vibration, the kinetic energy of the vibrating hammer 43 is effectively increased, thereby increasing the vibration force and improving the dust removal effect.

[0043] like Figure 1 and Figure 2 As shown, in a specific embodiment of the dust removal unit of the bag filter provided in this utility model, the tube sheet 10 is provided with multiple mounting holes, and there are multiple filter bags and vibrating components, which correspond one-to-one with the mounting holes. A transmission wheel 47 is fixedly connected to each drive shaft 44.

[0044] The drive assembly includes a drive element 61 and multiple transmission belts 63. The drive element 61 is fixedly connected to the mounting bracket 50 or the tube sheet 10, and the power output end is fixedly connected to the drive wheel 62. The multiple transmission belts 63 are sequentially connected to the drive wheel 62 and the transmission wheel 47, connecting the drive wheel 62 and all the transmission wheels 47 in series.

[0045] Specifically, the transmission belt 63 is a synchronous belt, and the drive wheel 62 and the transmission wheel 47 are synchronous pulleys; in addition, the transmission belt 63 can also be replaced by a transmission chain, in which case the drive wheel 62 and the transmission wheel 47 are both sprockets.

[0046] The drive element 61 is an existing motor or an assembly of a motor and a reducer.

[0047] By connecting the drive wheel 62 and all the drive wheels 47 in series with multiple drive belts 63, all the rapping components can be driven to work simultaneously by a single drive element 61, reducing the number of drive elements 61 used and controlling production costs.

[0048] Based on the same inventive concept, this utility model embodiment provides a bag filter dust collector, including the aforementioned bag filter dust collection unit.

[0049] The beneficial effects of the bag filter provided in this embodiment of the present invention are as follows: Compared with the prior art, the bag filter provided in this embodiment of the present invention uses the above-mentioned bag filter dust removal unit, so the bag body 21 is not easily damaged during the dust removal process.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
