Description
技术领域technical field
本发明涉及一种环保设备，特别涉及一种布袋除尘器。The invention relates to environmental protection equipment, in particular to a bag filter.
背景技术Background technique
布袋除尘器，其工作原理是利用布袋微孔过滤粉尘的，绝大部分粉尘直径是微米数量级，因为质量小，粉尘受静电或分子引力作用会黏在布袋上，使过滤孔越来越小，甚至堵死，所以要不断的清理，这一过程称为清灰。现用的清灰方法有人工清扫法和自动清灰法两种。人工清灰需要将滤袋拆除进行清扫，操作复杂，费时费力，自动清灰法主要有机械振动法、脉冲反吹法。机械振动法是驱动锤子敲击滤袋上方的安装部位，使滤袋发生振动，完成清灰，采用该方法清灰振动响声大，而且振动由于频率较高，也极易引发机器共振，导致损坏设备；脉冲反吹法则是利用高压气体高速射进滤袋内，使滤袋瞬间发生膨胀，从而抖落灰尘，但该方法由于气流压力大，气流高速射进滤袋内容易造成滤袋损伤，从而降低了除尘效果。The working principle of the bag filter is to use the micropores of the bag to filter the dust. Most of the dust diameter is on the order of microns. Because of the small mass, the dust will stick to the bag under the action of static electricity or molecular gravity, making the filter hole smaller and smaller. It is even blocked, so it needs to be cleaned continuously. This process is called dust removal. There are two kinds of cleaning methods in use: manual cleaning method and automatic cleaning method. Manual dust removal requires the filter bag to be removed for cleaning, which is complex, time-consuming and labor-intensive. The automatic dust removal methods mainly include mechanical vibration method and pulse backflushing method. The mechanical vibration method is to drive the hammer to hit the installation part above the filter bag to make the filter bag vibrate and complete the dust removal. Using this method, the dust removal vibration is loud, and the vibration is high in frequency, which can easily cause machine resonance and cause damage. Equipment; the pulse blowback method is to inject high-pressure gas into the filter bag at high speed, so that the filter bag expands instantly, thereby shaking off the dust. Thereby reducing the dust removal effect.

升降板701在与滤袋6相应位置处设有用于滤袋6穿过的通孔705，通孔705的直径大于滤袋6膨胀后的直径，通孔705的圆周处通过连接件安装有一圈毛刷706，并且毛刷706的刷毛与滤袋6的外表面接触。本实施例中，连接件采用轴承Ⅱ707，轴承Ⅱ707固定的套在通孔705的圆周内圈壁上，毛刷706固定在轴承Ⅱ707的内壁上，并且毛刷706与轴承Ⅱ707之间的设有倾角，毛刷706沿轴承Ⅱ707的径向倾斜向上，并且其倾斜角度为30°，这样能够为轴承Ⅱ707内壁再安装风扇叶片709提供了安装空间，也能够使毛刷706更轻松的戳进滤袋6的滤孔内，清灰更彻底。轴承Ⅱ707的内壁还固定有一圈风扇叶片709，风扇叶片709设有5个，5个风扇叶片709呈顺时针分布。The lifting plate 701 is provided with a through hole 705 for the filter bag 6 to pass through at the position corresponding to the filter bag 6. The diameter of the through hole 705 is larger than the diameter of the filter bag 6 after expansion. The circumference of the through hole 705 is installed with a ring through the connector A hair brush 706, and the bristles of the hair brush 706 are in contact with the outer surface of the filter bag 6. In this embodiment, the connecting piece adopts the bearing II 707, the bearing II 707 is fixedly set on the inner wall of the circumference of the through hole 705, the brush 706 is fixed on the inner wall of the bearing II 707, and the brush 706 and the bearing II 707 are provided with The inclination angle, the brush 706 is inclined upward along the radial direction of the bearing II 707, and its inclination angle is 30°, which can provide an installation space for the fan blade 709 on the inner wall of the bearing II 707, and can also make the brush 706 poke into the filter more easily In the filter hole of bag 6, dust removal is more thorough. A circle of fan blades 709 is also fixed on the inner wall of the bearing II 707. There are 5 fan blades 709, and the 5 fan blades 709 are distributed clockwise.
本发明为了使毛刷706能够时刻紧贴滤袋6的表面，使毛刷706与轴承Ⅱ707之间通过弹簧712连接。由于滤袋6膨胀后的直径并不是每个地方都一样，因而当升降板701上下运动时，毛刷706在弹簧712的作用下，能够随着滤袋6的直径变化而随时紧贴着滤袋6表面，便于毛刷706随时适应滤袋6直径的变化。弹簧712的固定则通过钢管套708来实现，钢管套708的数量与毛刷706的数量一致，并且钢管套708与毛刷706同轴，钢管套708的一端固定在轴承Ⅱ707的内侧，弹簧712设于钢管套708内，并且弹簧712的一端也固定在轴承Ⅱ707内侧上，毛刷706的端部同样置于钢管套708内，毛刷706通过弹簧712的作用在钢管套708内所伸缩运动。应当指出，钢管套708靠近滤袋6的端部所围成的圆周直径大于滤袋6的最大膨胀直径。In the present invention, in order to make the brush 706 close to the surface of the filter bag 6 at all times, the brush 706 is connected to the bearing II 707 through a spring 712 . Since the expanded diameter of the filter bag 6 is not the same everywhere, when the lifting plate 701 moves up and down, the brush 706, under the action of the spring 712, can stick to the filter bag 6 at any time as the diameter changes. The surface of the bag 6 is convenient for the brush 706 to adapt to the change of the diameter of the filter bag 6 at any time. The fixing of the spring 712 is realized by the steel pipe sleeve 708, the number of the steel pipe sleeve 708 is consistent with the number of the brushes 706, and the steel pipe sleeve 708 is coaxial with the brush 706, and one end of the steel pipe sleeve 708 is fixed on the inner side of the bearing II 707, and the spring 712 Set in the steel pipe sleeve 708, and one end of the spring 712 is also fixed on the inner side of the bearing II 707, the end of the brush 706 is also placed in the steel pipe sleeve 708, and the brush 706 expands and contracts in the steel pipe sleeve 708 through the action of the spring 712 . It should be pointed out that the diameter of the circle surrounded by the end of the steel pipe sleeve 708 close to the filter bag 6 is larger than the maximum expansion diameter of the filter bag 6 .
上腔体3内还固定分布有与滤袋6数量一样的气嘴31，气嘴31分别位于滤袋6的上方，并且气嘴31对着滤袋6的袋口内吹气，使滤袋6膨胀起来，气嘴31通过电磁阀与气流瓶连接，并且电磁阀通过控制系统控制，使用电磁阀控制气嘴31的气流，保证气嘴31吹出气流压力的平稳，防止气流脉冲的产升。The upper cavity 3 is also fixedly distributed with the same number of air nozzles 31 as the number of filter bags 6. The air nozzles 31 are respectively located above the filter bag 6, and the air nozzles 31 blow air against the bag mouth of the filter bag 6, so that the filter bag 6 When inflated, the gas nozzle 31 is connected to the airflow bottle through a solenoid valve, and the solenoid valve is controlled by the control system. The solenoid valve is used to control the airflow of the gas nozzle 31 to ensure the stability of the airflow pressure blown out by the gas nozzle 31 and prevent the generation of airflow pulses.
本发明为了增加升降板701两侧的空气流动，在升降板701上设有用于上下通气的气孔710，气孔710为倾斜的气孔，气孔710位于升降板701上表面的孔端朝向滤袋6倾斜，并且升降板701的上表面设有用于契合气孔710上端面的凹槽711，这样能够保证从升降板701下方流动到上方的尘气径直的流向滤袋6表面，并通过滤袋6表面过滤。In order to increase the air flow on both sides of the lifting plate 701 in the present invention, the lifting plate 701 is provided with an air hole 710 for ventilation up and down. The air hole 710 is an inclined air hole. , and the upper surface of the lifting plate 701 is provided with a groove 711 for fitting the upper end surface of the air hole 710, which can ensure that the dust gas flowing from the bottom of the lifting plate 701 to the top flows directly to the surface of the filter bag 6, and is filtered through the surface of the filter bag 6 .
本发明的清灰过程为：控制系统控制伺服电机8转动，伺服电机8通过减速器使驱动杆704缓慢转动，驱动杆704与驱动孔703配合，使升降板701通过T型块702沿竖直滑槽401向上运动，在升降板701向上运动过程中，滤袋6在气嘴31的吹气作用下保持膨胀状态，同时，滤袋6穿过升降板701的通孔705，而安装在通孔705内的毛刷706则对滤袋6表面进行清灰。由于尘气是从升降板701的下方进入下腔体4内的，而且尘气的压力较大，因而轴承Ⅱ707的风扇叶片709在尘气的作用下产生旋转力，类似于风车的原理，风扇叶片709带动轴承Ⅱ707转动，进而使毛刷706旋转，从而使毛刷706能够更彻底的清洁滤袋6的表面。当升降板701上升到极限位置时，T型块702上的接近开关发送信号至控制系统，使伺服电机8反转，使升降板701下降，在下降的过程中，由于风扇叶片709与尘气之间的相对压力更大，因此风扇叶片709的转动速度加快，使毛刷706的转速加快，从而轻松的剥落附着在滤袋6滤孔内的灰尘颗粒，当升降板701下降到极限位置时，接近开关再次发送信号至控制系统，使伺服电机8正转，循环上述过程。The cleaning process of the present invention is as follows: the control system controls the rotation of the servo motor 8, the servo motor 8 slowly rotates the driving rod 704 through the reducer, and the driving rod 704 cooperates with the driving hole 703, so that the lifting plate 701 passes through the T-shaped block 702 along the vertical direction. The chute 401 moves upwards. During the upward movement of the lifting plate 701, the filter bag 6 keeps expanding under the blowing action of the air nozzle 31. At the same time, the filter bag 6 passes through the through hole 705 of the lifting plate 701 and is installed in the through The brush 706 in the hole 705 then cleans the surface of the filter bag 6 . Since the dust gas enters the lower chamber 4 from the bottom of the lifting plate 701, and the pressure of the dust gas is relatively high, the fan blade 709 of the bearing II 707 generates a rotating force under the action of the dust gas, which is similar to the principle of a windmill. The blade 709 drives the bearing II 707 to rotate, and then the brush 706 rotates, so that the brush 706 can clean the surface of the filter bag 6 more thoroughly. When the lifting plate 701 rises to the limit position, the proximity switch on the T-shaped block 702 sends a signal to the control system to make the servo motor 8 reverse, and the lifting plate 701 is lowered. The relative pressure between them is greater, so the rotation speed of the fan blade 709 is accelerated, so that the rotation speed of the brush 706 is accelerated, thereby easily peeling off the dust particles attached to the filter holes of the filter bag 6, when the lifting plate 701 drops to the limit position , the proximity switch sends a signal to the control system again, so that the servo motor 8 rotates forward, and the above process is repeated.
本发明采用毛刷706与滤袋6直接接触的方式来清理滤袋6表面附着的积灰，不仅清灰效果好，而且还避免了振动，也能避免损伤滤袋，从而提高除尘器的使用寿命。The present invention uses brush 706 in direct contact with filter bag 6 to clean the dust accumulated on the surface of filter bag 6, which not only has a good dust removal effect, but also avoids vibration and damage to the filter bag, thereby improving the use of the dust collector life.
以上所述的仅是本发明的优选实施方式，应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, without departing from the inventive concept of the present invention, some modifications and improvements can also be made, and these all belong to the present invention. protection scope of the invention.
