技术领域Technical Field
本发明涉及化工过滤设备技术领域，具体为一种生产2,2-二硝基二苯氧基乙烷用废水中颗粒过滤机构。The invention relates to the technical field of chemical filtering equipment, in particular to a particle filtering mechanism in wastewater for producing 2,2-dinitrodiphenoxyethane.
背景技术Background Art
2,2-二硝基二苯氧基乙烷又称为1,2-双(2-硝基苯氧基)乙烷，是重要的化工原料，有望成为新型热敏材料增感剂和潜在的聚烯烃催化剂添加剂，因而在近年来生产规模逐步扩大，2,2-二硝基二苯氧基乙烷的化学合成工艺会排出大量污水。2,2-Dinitrodiphenoxyethane, also known as 1,2-bis(2-nitrophenoxy)ethane, is an important chemical raw material. It is expected to become a new type of thermosensitive material sensitizer and a potential polyolefin catalyst additive. Therefore, the production scale has gradually expanded in recent years. The chemical synthesis process of 2,2-dinitrodiphenoxyethane will discharge a large amount of wastewater.
现有专利（公开号：CN209828396U）公开了一种生产2,2-二硝基二苯氧基乙烷的过滤装置，该技术方案利用仓体构成废水流动通道，在进水端，设置一组常规进水管路和一组分散进水管路，后者末端设置有布水器，可将废水打散后与滤材接触，有助于提高颗粒物与滤材的接触面积，从而保证过滤效果；在此基础上，增设进气管路，可对仓体进行主动增压，有助于改善过滤速度；同时，基于筛网、微孔管、滤芯的三级递进结构，对不同粒径杂质分别拦截，缓解了单孔径滤芯易发生阻塞的问题；此外，本实用新型在仓体下部设置冷媒管，并依靠叶片扩大其换热面积，对过滤后的废水起到一定的冷却作用。应用本实用新型，有助于改善过滤速度和过滤效果，并降低输出端温度，具有良好的使用效果。在实现该实用新型的过程中发现存在如下问题：在长时间使用之后，装置中的过滤结构仍会发生堵塞，此时就需要将装置拆开才能够将对过滤结构进行清理，不方便使用。The existing patent (publication number: CN209828396U) discloses a filtering device for producing 2,2-dinitrodiphenoxyethane. The technical solution uses the warehouse to form a wastewater flow channel. At the water inlet end, a group of conventional water inlet pipelines and a group of dispersed water inlet pipelines are set. The latter is provided with a water distributor at the end, which can break up the wastewater and contact it with the filter material, which helps to increase the contact area between the particles and the filter material, thereby ensuring the filtering effect; on this basis, an additional air inlet pipeline is provided, which can actively pressurize the warehouse, which helps to improve the filtering speed; at the same time, based on the three-level progressive structure of the screen, microporous tube, and filter element, impurities of different particle sizes are intercepted separately, which alleviates the problem of easy blockage of the single-aperture filter element; in addition, the utility model sets a refrigerant pipe at the bottom of the warehouse, and relies on the blades to expand its heat exchange area, which plays a certain cooling role on the filtered wastewater. The application of the utility model helps to improve the filtering speed and filtering effect, and reduce the temperature at the output end, with good use effect. In the process of implementing the utility model, the following problems were found: after long-term use, the filter structure in the device will still be clogged, and at this time the device needs to be disassembled to clean the filter structure, which is inconvenient to use.

在本实施例中，所述驱动电机705，电磁阀一5和电磁阀二1010均与拨动开关6电性连接，当拨动开关6通电时，驱动电机705启动，电磁阀一5闭合，电磁阀二1010打开，当拨动开关6断电时则反之。In this embodiment, the drive motor 705, solenoid valve 1 5 and solenoid valve 2 1010 are all electrically connected to the toggle switch 6.

在本实施例中，所述底板3上开有出水口一301和出水口二302，所述出水口二302抵接在下层的安装盘902上的排水孔一904处。In this embodiment, a water outlet 1 301 and a water outlet 2 302 are formed on the bottom plate 3 , and the water outlet 2 302 abuts against the drainage hole 1 904 on the mounting plate 902 of the lower layer.
在本实施例中，出水口一301用于排出过滤之后的废水，出水口二302用于排出反冲时筒体1内积存的废水和反冲形成的污水，这部分废水和污水可以重新过滤利用。In this embodiment, the water outlet 1 301 is used to discharge the waste water after filtration, and the water outlet 2 302 is used to discharge the waste water accumulated in the cylinder 1 during backflushing and the sewage formed by backflushing, which can be re-filtered and reused.
该种生产2,2-二硝基二苯氧基乙烷用废水中颗粒过滤机构在工作时，工作过程如下：When the particle filtering mechanism in the wastewater used for producing 2,2-dinitrodiphenoxyethane is working, the working process is as follows:
正常情况下，废水从废水进入管4穿过电磁阀一5后进入筒体1，而后在上层的过滤网903过滤后，从上层的安装盘902上的排水孔二905流到下层的集水盘901上，而后又通过下层的过滤网903进行二次过滤，并最终从出水口一301排出；Under normal circumstances, wastewater enters the cylinder 1 through the wastewater inlet pipe 4 and passes through the solenoid valve 15, and then after being filtered by the filter screen 903 at the upper layer, it flows from the drainage hole 2 905 on the mounting plate 902 at the upper layer to the water collecting plate 901 at the lower layer, and then passes through the filter screen 903 at the lower layer for secondary filtration, and finally is discharged from the water outlet 301;
当过滤网903被堵塞后，筒体1中的废水持续积存，筒体1内的水压变大，使得活塞杆803受到的向上的推力越来越大，通过楔形块804对拨动杆601的推力也逐渐增大，当推力超过弹簧712的弹力时，拨动杆601会在楔形块804的推动下移动，使拨动开关6通电，闭合电磁阀一5停止通入废水，打开电磁阀二1010通入反冲的净水，驱动电机705启动；When the filter screen 903 is blocked, the waste water in the cylinder 1 continues to accumulate, and the water pressure in the cylinder 1 increases, so that the upward thrust on the piston rod 803 becomes larger and larger, and the thrust on the toggle rod 601 through the wedge block 804 gradually increases. When the thrust exceeds the elastic force of the spring 712, the toggle rod 601 will move under the push of the wedge block 804, so that the toggle switch 6 is energized, the electromagnetic valve 1 5 is closed to stop the waste water from entering, and the electromagnetic valve 2 1010 is opened to allow the recoil clean water to enter, and the drive motor 705 is started;
驱动电机705通过带轮一703带动皮带704旋转，由于皮带704上的导杆一706滑动连接在连接块709上的导槽一710中，当皮带704转动时，与连接块709相连的齿条708会被带动移动，移动的齿条708带动啮合的从动齿轮1002正向旋转一定圈数，从动齿轮1002带动与之固定连接的转动杆一1001旋转，在带传动组件1016的传动下，圆筒1014和另一根转动杆一1001也会旋转；The driving motor 705 drives the belt 704 to rotate through the pulley 703. Since the guide rod 706 on the belt 704 is slidably connected to the guide groove 710 on the connecting block 709, when the belt 704 rotates, the rack 708 connected to the connecting block 709 will be driven to move, and the moving rack 708 drives the meshing driven gear 1002 to rotate forward for a certain number of circles. The driven gear 1002 drives the rotating rod 1001 fixedly connected thereto to rotate. Under the transmission of the belt transmission assembly 1016, the cylinder 1014 and the other rotating rod 1001 will also rotate;
由于导杆二1013滑动连接在导槽二1015中，圆筒1014旋转带动滑动套筒1011上移，滑动套筒1011带动转动杆二1012和塞块1017上移，使两个排水孔一904打开，排出筒体1内积存的废水；Since the guide rod 1013 is slidably connected in the guide groove 1015, the cylinder 1014 rotates to drive the sliding sleeve 1011 to move upward, and the sliding sleeve 1011 drives the rotating rod 1012 and the plug 1017 to move upward, so that the two drainage holes 904 are opened to discharge the waste water accumulated in the cylinder 1;
转动杆一1001旋转带动丝杆1003旋转，从而带动与螺母支架1004和封闭环1005上移，使封闭环1005的内侧面抵接到过滤网903的上端，同时折叠围板1006也随封闭环1005的上移而展开，使从导水管一1007和导水管二1008通入的净水存于折叠围板1006和过滤网903之间的空隙中，随着净水的持续通入，净水的水压增大，冲开堵塞的过滤网903，实现反冲洗的效果；The rotation of the rotating rod 1001 drives the screw rod 1003 to rotate, thereby driving the nut bracket 1004 and the closed ring 1005 to move upward, so that the inner side of the closed ring 1005 abuts against the upper end of the filter screen 903, and at the same time, the folding enclosure 1006 is also unfolded with the upward movement of the closed ring 1005, so that the clean water introduced from the water pipe 1 1007 and the water pipe 2 1008 is stored in the gap between the folding enclosure 1006 and the filter screen 903. With the continuous introduction of clean water, the water pressure of the clean water increases, flushing the blocked filter screen 903, and achieving the effect of backwashing;
皮带704旋转时带动相连的带轮二1104旋转，带轮二1104通过传动的机构带动转动轴四1106旋转，转动轴四1106带动转动杆二1012旋转，转动杆二1012带动旋转套筒1109转动，由于导杆三1112滑动连接在导槽三1110中，连接升降环架1111会随旋转套筒1109的转动二往复升降，带动柔性刷毛1113上下移动刷洗过滤网903内壁，进一步提升清理的效果；When the belt 704 rotates, it drives the connected pulley 2 1104 to rotate, and the pulley 2 1104 drives the rotating shaft 4 1106 to rotate through the transmission mechanism, and the rotating shaft 4 1106 drives the rotating rod 2 1012 to rotate, and the rotating rod 2 1012 drives the rotating sleeve 1109 to rotate. Since the guide rod 3 1112 is slidably connected in the guide groove 3 1110, the connecting lifting ring frame 1111 will reciprocate and rise and fall with the rotation of the rotating sleeve 1109, driving the flexible bristles 1113 to move up and down to brush the inner wall of the filter screen 903, further improving the cleaning effect;
齿条708会随皮带704的旋转反向移动，带动从动齿轮1002反向旋转，从而使封闭环1005和塞块1017复位，在连接块709反向移动至最初位置的过程中，推杆711会抵接到拨动杆601上，由于此时活塞杆803下方没有做够足够的推力支持，拨动杆601会在推杆711的推动下复位，使拨动开关6断开，驱动电机705关闭，电磁阀一5打开重新通入废水，电磁阀二1010关闭停止通入净水；The rack 708 will move in the opposite direction with the rotation of the belt 704, driving the driven gear 1002 to rotate in the opposite direction, thereby resetting the closed ring 1005 and the plug 1017. When the connecting block 709 moves in the opposite direction to the initial position, the push rod 711 will abut against the toggle rod 601. Since there is no sufficient thrust support under the piston rod 803 at this time, the toggle rod 601 will be reset under the push of the push rod 711, so that the toggle switch 6 is disconnected, the drive motor 705 is turned off, the solenoid valve 1 5 is opened to re-introduce waste water, and the solenoid valve 2 1010 is closed to stop the introduction of clean water;
当过滤网903再次堵塞时，又会自动重复上述清理步骤。When the filter 903 is clogged again, the above cleaning steps will be automatically repeated.
