  • the invention relates to the field of machinery, in particular to a backwash filter and a rotary backwash filter in a water purification technology, and to wet solid particle purification and grading and sorting treatment.
  • the backwash filter used in the known wastewater purification water treatment technology is necessary in the purification process. It plays a role in intercepting impurities in the water.
  • the raw water enters the filter and flows through the filter screen to become clean water.
  • the impurities in the raw water are intercepted by the filter screen in the filter, so that they adhere to or clog on the surface of the filter screen mesh, affecting the filtering effect and water output of the filter. Therefore, it is necessary to reversely flush the filter screen of the filter to remove the impurities on the surface of the filter screen mesh to restore the processing capacity of the filter.
  • the existing backwash filter screen cleaning system is under the pressure difference transmitter controller, and the motor is used to drive its transmission mechanism in forward and reverse rotation, so that the cleaning nozzle and the suction pipe are radially rotated and axially reciprocated around the filter screen on both sides of the filter fixed filter screen, and the nozzle sprays high-pressure water flow to the outside of the filter screen to reversely flush the filter screen.
  • the impurities washed away are sucked in by the suction pipe and discharged.

Description

多功能自旋转冲洗过滤反应装置 技术领域
本发明涉及机械领域，尤其涉及净化水处理技术中的反冲洗过滤器、旋转反冲洗过滤器，涉及湿法固体颗粒物净化和分级分选处理。
背景技术
目前，公知的废水净化水处理技术过程中使用的反冲洗过滤器在净化过程中是必要的，它起着拦截水中的杂质作用，在废水处理过程中，原水由进入过滤器流经滤网后成为净水，原水中的杂质被过滤器内的滤网拦截，使其附着或堵塞在滤网网孔表面上，影响过滤器的过滤效果和出水量，因此对过滤器的滤网反向冲洗，去掉滤网网孔表面上的杂质来恢复过滤器的处理能力是必要的。现有的反冲洗过滤器的滤网清洗系统是在压力差变送控制器下，采用电动机正反转带动其传动机构，使其清洗喷嘴和吸管在过滤器固定滤网的两侧围绕滤网做径向旋转和轴向往复运动，同时喷嘴向滤网外侧喷出高压水流，对滤网进行反向冲洗，被冲洗掉的杂质由吸管吸入后排出，喷嘴吸管沿滤网内处两侧以正反包络螺旋线的运动方式覆盖滤网来达到清洗目的。有的过滤器在滤网内侧吸管附近加装刮板用来松动杂质，也有的过滤器在滤网内侧加装毛刷来松动杂质和加装弹性吸管来吸杂质。这些都是为了冲洗掉滤网网孔处的杂质来达到清洗目的要求。
这几种反冲洗过滤器的机械装置结构复杂，制造成本高，电动机正反转频繁启动耗能高，设备运行成本高，喷嘴的高压水流对滤网的冲击力大，减少了滤网的使用寿命。以上几种反冲洗过滤器之所以这样复杂，其根本在于运行过程中滤网网孔被杂质堵塞，堵塞的杂质在水流的冲击下附着在滤网内表上，越积越多，杂质层越厚，只有堵到一定程度后出现了原水腔体与净水腔内的压差达到一定数值后，才开启清洗系统，这样就出现了清洗困难。也就是不堵塞到一定程度，清洗系统不会工作。因此，降低了过滤器的工作效率，运行成本和维修成本高。

如图1所示，多功能自旋转冲洗过滤反应装置，它包括主体机座21，在主体机座21上端设置上封盖25，下端设置下封盖52，下封盖52的底部连接主排污通道，主排污通道的端部为主排污口1。在主体机座21内部从上到下依次设置上隔板22-1、中隔板22-2和下隔板22-3，这样，上隔板22-1与主体机座21顶部之间为净水收集腔体61，上隔板22-1与中隔板22-2之间为大净水腔体18，中隔板22-2与下隔板22-3之间为原水腔体45，下隔板22-3与主体机座21底部之间为小净水腔体51和污水腔体47，在小净水腔体51与污水腔体47之间用小滤网50隔开。

上隔板22-1上设置上隔板过水孔26，净水收集腔体61通过上隔板过水孔26连通大净水腔体18，在净水收集腔体61的一侧设置净水出水口35。进一步地，在净水收集腔体61的另一侧设置加料电动阀23和加料泵24，加料电动阀23和加料泵24固定在主体机座21的侧壁上，且加料电动阀23和加料泵24也与PLC控制器54相连接。
在大净水腔体18与原水腔体45之间用大滤网17隔开，大滤网17上下两端分别由止口27固定在上隔板22-1和中隔板22-2上。进一步地，大滤网17的下部设置导流环16，便于原水进入大滤网17内部。
如图1、图2所示，在原水腔体45和污水腔体47内设置旋转吸污装置20，旋转吸污装置20包括轴向设置的空心轴20-1，空心轴20-1上端通过上轴承座30与上隔板22-1连接， 空心轴20-1下端通过下轴承座42、单列向心球轴承43和平面推力轴承44、密封圈41与下隔板22-3相连接，上隔板22-1和下隔板22-3为旋转吸污装置20提供支撑，使旋转吸污装置20能够自由旋转。
旋转吸污装置20还包括若干个与空心轴20-1连通的排污管38，每个排污管38内均设置排污通道39，进而排污通道39与空心轴20-1连通。多个排污管38按照螺旋线在轴向方向垂直分布，且每个排污管38垂直于空心轴20-1设置，多个排污管38构成螺旋浆叶轮机构。排污管38的一端与空心轴20-1连通，另一端靠近大滤网17的内表面处。需要说明的是，在大滤网17内表面与排污通道39之间围成一个间隙区域19，该间隙区域19为旋转吸污空间，这个间隙区域19跟随螺旋浆叶轮机构的转动而做变化，变化的轨迹为圆周运动。
进一步地，排污通道39与大滤网17内表面的间隙大于保安过滤装置14中的保安滤网13的网孔直径，从而保证了原水中的污物杂质能够从排污通道39中排出。
旋转吸污装置20下方设置喷水口装置48，喷水口装置48工作在污水腔体47中，喷水口装置48包括与空心轴20-1相连通的喷水管20-2，喷水管20-2位于空心轴20-1下端，且与空心轴20-1垂直设置，喷水管20-2的末端设置喷水口，喷水口朝向助推板49，助推板49设置在主体机座21的内壁上。需要说明的是，助推板49在主体机座21内壁上沿圆周分布，可以为多个间断设置的助推板，也可以为一个连续的圆环型助推板。
旋转吸污装置20下方设置小滤网50，小滤网50将小净水腔体51和污水腔体47隔开。小滤网50的形状可以为平面滤网，也可以为带折弯结构的滤网。小净水腔体51与正反向水管37相连通，正反水通道40设置在正反向水管37内，正反向水管37的另一端分别连接净水出水管36和反冲洗引水管33，净水出水管36和反冲洗引水管33最后均连接至净水出水口35。
进一步地，在净水出水口35设置稳流管32，净水出水管36和反冲洗引水管33均通过稳流管32连接至净水出水口35。
如图3、图4所示，原水流动方向为：原水从原水进水口15进入原水腔体45内，由于下隔板22-3的阻隔，一部分原水从下部进入大滤网17，经大滤网17过滤后进入大净水腔体18，该部分净水穿过上隔板过水孔26进入净水收集腔体61，最后从净水出水口35排出，这部分原水完成了过滤净化，原水中的污物杂质被大滤网17拦截，附着在大滤网17内表面网孔处。另一部分原水进入从下部进入大滤网17内部后而进入旋转吸污装置20，经旋转吸污装置20上的排污管38进入排污通道39，从排污通道39进入空心轴20-1，在压差作用下至喷水口装置48的喷水管20-2，然后喷射到污水腔体47中，通过小滤网50进入小净水腔 体51，经正反向水管37的正反水通道40，从净水出水口管36至净水出水口35排出，原水中的污物杂质被小滤网50拦截，附着在小滤网50的内表面网孔处。
本发明中，运行和清洗同时进行的工作原理是：
旋转吸污装置20上部设置在大滤网17和导流环16中心，原水进入原水腔体45区，在导流环16的作用下，原水经导流环16冲击螺旋浆叶轮机构做功，螺旋浆叶轮机构在大滤网17和导流环16内受到轴向水流的冲击产生推力，使旋转吸污装置20旋转起来。同时，下部喷水口装置48设置在旋转吸污器20下端的污水腔体47中，多个排污管38吸取的污水，通过空心轴20-1流至喷水管20-2的末端的喷水口20-3，从喷水口20-3喷射到污水腔体47内的助推板49上。喷水口装置48在污水腔体47中沿切线方向对圆周多个助推板49喷射水流，喷嘴射出的水流沿切线方向对助推板49喷射做功，产生推力。螺旋浆叶轮机构产生的推力和喷水口装置48产生的推力方向一致，从而推动旋转吸污装置20转动。
需要说明的是，如图4所示，在喷水管20-2的两端均设置喷水口20-3，喷水口20-3的轴向方向与喷水管20-2的轴向方向相垂直为最佳实施方式。
在旋转吸污装置20的转动过程中，原水中污物杂质被原水推压在大滤网17的内表面堵在网孔上，在大滤网17内表面与排污通道39之间围成一个间隙区域19，这个间隙区域19跟随螺旋浆叶轮转动做圆周运动，即堵塞在大滤网17网孔上的污物杂质最多只能停留1/n转，n为螺旋叶轮的叶片数，随即被压入排污通道39后，被送入污水腔体47。在间隙区域19内净水是通过大滤网17网孔冲入排污通道39，这个堵在网孔上的污物杂质被水流冲击松动后被压入排污通道排出，完成了不停机的连接清洗，提高了净水出水量。
进一步地，为增强排污效果，设置强制排污通道62，强制排污通道62下方为强制排污口，强制排污通道62连通至主排污通道，在强制排污通道62上设置强制排污电动阀6和强制排污泵8，其中，强制排污泵8的压力大于原水腔体45内的压力。为实现自动化控制，在主排污通道内设置主排污电动阀53，主排污电动阀53或强制排污电动阀6和强制排污泵8，两者一开一闭。上述的强制排污电动阀6、强制排污泵8和主排污电动阀53均与PLC控制器54相连接。
关闭主排污电动阀53和强制排污电动阀6，螺旋浆水轮机构的排污通道39把大滤网17内表面网孔处含有污物杂质的原水压进入污水腔体47。
进一步地，在正反向水管37内设置引水管阻尼板34。引水管阻尼板34可以为设置在正反向水管37内的蝶阀，也可以为一个截面为三角形的调节板，该调节板固定在转轴上，通过电机控制转轴转动，来控制调节板的转动角度；根据转动角度，来调节反冲洗引水管 33和净水出水管36的开度。这样，在未开启主排污电动阀53和/或强制排污电动阀6排污时，引水管阻泥板34来调节正反水通道40，从而控制旋转吸污装置20的转速。在开启主排污电动阀53或强制排污电动阀6时，引水管阻泥板34可调节对小滤网50的反洗强度。
为实现进一步自动控制，在原水腔体45内设置获取原水压力的原水腔压差变送器12，在污水腔体47内设置获取污水压力的污水腔体压差变送器11，在小净水腔体51内设置获取净水压力的小净水腔体压差变送器9，在保安过滤装置14内设置获取保安压力的保安压差变送器10、在正反向水管37内设置流量传感器60。上述的原水腔压差变送器12、污水腔体压差变送器11、小净水腔体压差变送器9、保安压差变送器10、流量传感器60均与PLC控制器54相连接。
本发明中的冲洗程序设定为流量传感器60为主清洗程序传感器，小净水腔体压差变送器9、保安压差变送器10、污水腔体压差变送器11、原水腔压差变送器12做为第二清洗传感器，给PLC控制器54提供信号指令。
由PLC控制器收到流量传感器60设定值后，开启主排污电动阀53，增大了大净水腔体18的净水对间隙区域19的水流压力，加大了对大滤网17网孔的反向冲洗力，网孔处污物杂质松动被压入污水腔体47从主排污口1排出。反向清洗小滤网50时，部分净水经净水出水口35、反冲洗引水管33、正反向水管37、正反水通道40进入小净水腔体51，通过小滤网50后进入污水腔体47，把堵塞在小滤网50内表面网孔上的污物杂质冲击松动排出，对小滤网50反向冲洗。
本装置在联机运行时可根据需要配备装置和设定运行程序。
进一步地，保安过滤装置14设置有二次抽水口2，二次抽水口2设置在二次抽水管道64上，二次抽水管道64与保安排污管道63连通。在二次抽水管道64上设置二次抽水电动阀5和二次抽水泵7，二次抽水电动阀5和二次抽水泵7均与PLC控制器54相连接。
进一步地，在保安排污口3、强制排污口、二次抽水口2和主排污口1的下方设置有污水沉淀槽57，污水沉淀槽57内设置污物输送机58，污水沉淀槽57侧方设置污物出口59，污物杂质由污物输送机58送至污物出口59排出，污水沉淀槽57中的沉淀水由二次抽水口2经二次抽水泵7送入保安过滤装置14中，最终送至原水进水口15。需要说明的是，污物输送机58由排污槽控制器56控制，排污槽控制器56与PLC控制器54相连接。
必要地，PLC控制器54上连接有电源线接口55，上隔板下方有止口27、大滤网17，这些为现有技术，在此不再赘述。
在上封盖25上设置有排气阀28、压力表29和安全阀31，这些均为现有技术。
本发明的工作过程是：
原水被压入原水腔体45内经两路过滤后流出，一路通过大滤网17进入大净水腔体18上接至净水出水口35流出，另一路沿旋转吸污装置20的螺旋浆叶轮机构，经排污管38的排污通道39从喷水口装置48进入污水腔体47，通过小滤网50至小净水腔体51后，由正反水通道40经净水出水管36至净水出水口35流出。原水通过大滤网17被拦截下的原水中的污物杂质附着在大滤网17内表面并堵塞在大滤网的网孔上，同样在污水腔体47的原水通过小滤网50被拦截下的原水中的污物杂质也附着在小滤网内表面堵塞在小滤网的网孔上。
螺旋桨叶轮机构是在旋转吸污装置20，沿空心轴20-1连通有多个排污管38，排污管38的排污通道39与空心轴20-1相连通，多个排污管38按螺旋线排列螺旋面构成了螺旋桨叶轮，设置在原水腔体内的大滤网17和导流环16内，在水流的冲击下的叶轮成为水轮机来为旋转吸污装置20提供动力。另一个设置在空心轴下端的喷水口装置48，原水由排污通道39经空心轴20-1内从喷水口装置48喷射到助推板49上，喷射的水流柱沿切线方向喷射，从而也获得径向推动力，这两个力的方向是同方向推动旋转吸污装置20旋转，转速由引水管阻尼板34调节。在大滤网17内表面与旋转吸污装置20的排污通道39口之间有大于保安滤网孔径的曲面的间隙区域19，带有污物杂质的原水从这个间隙区域19的周围被压入排污通道39，这个间隙区域19内水流方向有两个，一个是从间隙区域19的周围流向排污通道39，另一个是朝向大滤网17内表面，在这个区域间隙水流方向由大净水腔体18通过大滤网17被压入排污通道39，在这个过程中水流对滤网孔冲击使堵塞在大滤网17网孔上的污物杂质松动被压入排污通道39。一个排污通道39随着旋转吸污装置的旋转清洗一个环形区域，多个排污通道39随着旋转就覆盖了整个大滤网17内表面，完成了未开启排污电动阀时大滤网的反冲洗，开机运行同步清洗，因此，大滤网网孔不会被污物杂质堵塞，从而提高了效率。
当主排污电动阀53开启后，污水腔体47内的含污物杂质的原水排出有两种情况，一种是主排污电动阀53开启后，污水腔体47内压力迅速下降迫使大净水腔体18内水流加大了对大滤网17的间隙区域19处反冲洗力度，二是污水腔体47内的水压下降使得处于高水压的净水从正反向水管的正反向水管36进入小净水腔体内对小滤网50进行反冲洗，附着在小滤网50内表面上的污物杂质反方向水流冲击而松动被排出。关闭主排污电动阀53，开启强制排污电动阀6和强制排污泵8为强制排污，泵的压力大于原水腔体内压力。
另外，多功能自旋转冲洗过滤反应装置还有一个新用途。将一个多功能自旋转冲洗过滤反应装置的净水出水管36通过外接管道65连接另一个多功能自旋转冲洗过滤反应装置的原 水进水口15，可作为湿法选矿、磨料行业、制砂行业、污水处理行业等的生产线，进行颗粒固体的分级分选。在分级分选时，根据颗粒固体的粒径，对依次设置的多个多功能自旋转冲洗过滤反应装置中的大滤网17和小滤网50的孔径依次进行调整，这样，小于大滤网17和小滤网50孔径的颗粒固体进入下一级，大于其孔径的从本级的主排污口1排出。在分级分选中，N个装置之间设置加料电动阀23、加料泵24和排气阀28可组成多级反应器处理多种液体产品。进一步地，强制排污电动阀6和强制排污泵8也需要安装到级联的装置中。
以上所述的仅是本发明的优选实施方式，应当指出，对于本领域的技术人员来说，在不脱离本发明整体构思前提下，还可以作出若干改变和改进，这些也应该视为本发明的保护范围。
