Description

一种混凝土生产污水综合处理设备及处理工艺A comprehensive treatment equipment and treatment process for concrete production wastewater

技术领域Technical Field

本发明涉及污水处理技术领域,特别涉及一种混凝土生产污水综合处理设备及处理工艺。The present invention relates to the technical field of sewage treatment, and in particular to a comprehensive treatment device and process for sewage from concrete production.

背景技术Background Art

混凝土在生产过程中产生的污水中富含水泥、砂石、粉煤灰、矿粉、外加剂等强碱性物质,PH值和不溶物含量均较高,若将混凝土污水直接排放,不但造成了水资源和混凝土原料的浪费,而且也会对环境造成污染。The wastewater generated during the production of concrete is rich in strong alkaline substances such as cement, sand, fly ash, mineral powder, admixtures, etc., and has a high pH value and insoluble matter content. If the concrete wastewater is discharged directly, it will not only cause a waste of water resources and concrete raw materials, but also pollute the environment.

在混凝土的绿色生产中,需要对其生产污水进行处理并将处理后的污水用于混凝土生产中,以此实现混凝土污水中砂、石的重新利用和混凝土污水的零排放,进而对混凝土污水进行净化处理,从而减少成本和对环境的污染。In the green production of concrete, it is necessary to treat the wastewater produced and use the treated wastewater in concrete production, so as to achieve the reuse of sand and stone in concrete wastewater and zero discharge of concrete wastewater, and then purify the concrete wastewater to reduce costs and pollution to the environment.

现有技术中,也公开了大量的混凝土污水处理及相应的装置,其中,如公开号为CN115572010A的中国专利公开了一种混凝土生产废水处理系统及方法,包括调节池、沉淀池、污泥浓缩池、清水池、调节池提升泵、酸加药单元和絮凝剂加药单元;调节池的调节池提升泵的第一输水管道的出口与调节池进水管连通,第二输水管道连通到沉淀池的进水端;沉淀池的上清液连通到清水池;沉淀池的排污泥管连通到污泥浓缩池;污泥浓缩池具有与调节池连通的上清液溢流孔。In the prior art, a large number of concrete wastewater treatments and corresponding devices are also disclosed. Among them, for example, a Chinese patent with publication number CN115572010A discloses a concrete production wastewater treatment system and method, including a regulating tank, a sedimentation tank, a sludge thickening tank, a clear water tank, a regulating tank lifting pump, an acid dosing unit and a flocculant dosing unit; the outlet of the first water delivery pipeline of the regulating tank lifting pump of the regulating tank is connected to the regulating tank water inlet pipe, and the second water delivery pipeline is connected to the water inlet end of the sedimentation tank; the supernatant of the sedimentation tank is connected to the clear water tank; the sludge discharge pipe of the sedimentation tank is connected to the sludge thickening tank; the sludge thickening tank has a supernatant overflow hole connected to the regulating tank.

上述现有技术在使用时,通过酸加药单元向调节池内的混凝土生产废水中添加酸液并搅拌均匀,随后通过调节池提升泵将废水和酸液的混合液提升至沉淀池,期间通过絮凝剂加药单元向混合液添加絮凝剂;随后沉淀池的上清液流入清水池,沉淀池的污泥流入污泥浓缩池;最后清水池中的清水被提升至回用水点,污泥浓缩池的上清液通过溢流孔回流至调节池,浓缩污泥被输送至指定弃土场。When the above-mentioned prior art is in use, acid liquid is added to the concrete production wastewater in the equalization tank through the acid dosing unit and stirred evenly, and then the mixed liquid of the wastewater and the acid liquid is lifted to the sedimentation tank through the equalization tank lifting pump, during which flocculant is added to the mixed liquid through the flocculant dosing unit; then the supernatant of the sedimentation tank flows into the clear water tank, and the sludge in the sedimentation tank flows into the sludge thickening tank; finally, the clear water in the clear water tank is lifted to the reuse water point, the supernatant of the sludge thickening tank is returned to the equalization tank through the overflow hole, and the concentrated sludge is transported to the designated landfill.

然而,在采用上述现有技术对混凝土废水进行处理的过程中,还有以下不足之处:However, in the process of treating concrete wastewater using the above-mentioned prior art, there are still the following shortcomings:

1、上述现有技术通过添加絮凝剂的方式可以使混凝土生产废水中的污泥沉淀,但是混凝土生产废水中不仅含有污泥,还可能掺杂有砂石和直径较大的块状物,砂石和块状物均可以回收用作建筑施工,而上述现有技术无法将砂石和块状物滤除,导致砂石和块状物随浓缩污泥一同输送至弃土场,不仅加剧建筑原料的损耗,增加成本,还可能存在砂石和块状物在弃土场中无法分解的情况。1. The above-mentioned prior art can precipitate the sludge in the concrete production wastewater by adding flocculants. However, the concrete production wastewater contains not only sludge, but also sand and gravel and lumps with larger diameters. The sand and gravel and lumps can be recycled for construction, but the above-mentioned prior art cannot filter out the sand and gravel and lumps, resulting in the sand and gravel and lumps being transported to the waste land along with the concentrated sludge, which not only aggravates the loss of construction materials and increases costs, but also may cause the sand and gravel and lumps to be unable to decompose in the waste land.

2、虽然通过絮凝剂可以将混凝土生产废水中的污泥沉淀,但是将沉淀池的上清液流入清水池时容易使其底部的污泥翻腾并扬起至上清液中,因此导致回收的清水中仍然含有絮凝后的污泥,从而影响清水的使用效果。2. Although the sludge in the concrete production wastewater can be precipitated by flocculants, when the supernatant of the sedimentation tank flows into the clean water tank, the sludge at the bottom is easily churned and lifted into the supernatant. As a result, the recovered clean water still contains flocculated sludge, which affects the use effect of the clean water.

因此,在上述陈述的观点之下,现有技术的混凝土污水手段还有可提高的空间。Therefore, based on the above-stated viewpoints, there is still room for improvement in the concrete sewage treatment technology of the prior art.

综上所述,本申请包括以下至少一种有益技术效果:In summary, the present application includes at least one of the following beneficial technical effects:

一、本发明通过砂块过滤斗、承接筒、过滤单元和分离单元之间的相互配合能够依次对混凝土污水进行第一次过滤、酸碱性中和处理以及二次过滤,从而可以有效的滤除混凝土污水中的块状物和砂石以及调节混凝土污水的PH值,以确保过滤净化后的水、滤除的块状物和砂石能够回收重复利用,从而能够有效的减少成本、建筑垃圾以及污水排放。1. The present invention can sequentially perform the first filtration, acid-base neutralization treatment and the second filtration on concrete sewage through the mutual cooperation among the sand block filter bucket, the receiving cylinder, the filter unit and the separation unit, thereby effectively filtering out the lumps and sand and gravel in the concrete sewage and adjusting the pH value of the concrete sewage to ensure that the filtered and purified water, the filtered lumps and sand and gravel can be recycled and reused, thereby effectively reducing costs, construction waste and sewage discharge.

二、本发明通过拨杆和拨齿周向转动可以将混凝土污水中直径较大的块状物拨动至收集箱内,使得收集箱对块状物进行收集,从而实现混凝土污水的第一次过滤;在此期间,通过抵触块和定位块之间的相配合能够控制砂块过滤斗的上下振动,从而能够提高对混凝土污水和块状物的筛分效率。Second, the present invention can move the lumps with larger diameters in the concrete sewage into the collection box through the circumferential rotation of the lever and the teeth, so that the collection box collects the lumps, thereby realizing the first filtration of the concrete sewage; during this period, the up and down vibration of the sand block filter bucket can be controlled by the cooperation between the resistance block and the positioning block, thereby improving the screening efficiency of the concrete sewage and lumps.

三、本发明通过支撑轴带动套筒和执行杆同步转动可以对承接筒内部的混凝土污水和酸液进行搅拌,以便于对混凝土污水进行酸碱中和处理;期间通过圆形板上下往复缓慢移动能够分别对承接筒的中部进行封闭和打开,封闭时可以使圆形板上端的混凝土污水和酸液具有充足的混合时间,以此增强对混凝土污水的中和效果,打开时便于将中和后的混凝土污水从承接筒内排出。3. The present invention can stir the concrete sewage and acid liquid inside the receiving tube by driving the sleeve and the actuator rod to rotate synchronously through the support shaft, so as to facilitate the acid-base neutralization treatment of the concrete sewage; during the process, the middle part of the receiving tube can be closed and opened respectively by the circular plate moving up and down slowly reciprocating. When closed, the concrete sewage and acid liquid on the upper end of the circular plate can have sufficient mixing time, thereby enhancing the neutralization effect of the concrete sewage. When opened, it is convenient to discharge the neutralized concrete sewage from the receiving tube.

四、本发明通过过滤垫能够滤除混凝土污水中直径较小的砂石,且通过收集斗可以将过滤垫上端的砂石带出至处理筒外部,以此完成对混凝土污水的第二次过滤,且能够实现砂石和水之间的分离。Fourth, the present invention can filter out sand and gravel with smaller diameters in concrete sewage through the filter pad, and the sand and gravel on the upper end of the filter pad can be brought out to the outside of the treatment tube through the collecting bucket, thereby completing the second filtration of the concrete sewage and realizing the separation between sand and gravel and water.

五、本发明通过向处理筒中投放絮凝剂可以将混凝土污水中的细小灰尘和杂质形成沉淀在接收框内的絮凝杂质,从而可以防止抽出过滤后净水时引起絮凝杂质在水中扬起而导致净水出现浑浊的情况,以此能够对混凝土污水进行再次分离,以便于去除水中的絮凝杂质,从而确保过滤后水中不含有杂质且能够重新回收利用,进而减少水资源的浪费,且可以有效避免直接排放混凝土污水而污染环境。5. The present invention can form flocculated impurities in the concrete sewage into flocculated impurities by adding flocculants into the treatment barrel, thereby preventing the flocculated impurities from being lifted up in the water and causing the purified water to become turbid when the purified water is extracted after filtration. In this way, the concrete sewage can be separated again to remove the flocculated impurities in the water, thereby ensuring that the filtered water does not contain impurities and can be recycled, thereby reducing the waste of water resources and effectively avoiding the direct discharge of concrete sewage to pollute the environment.

六、本发明通过升降板向下移动可以对处理筒的底部封闭,再通过抽水泵将处理筒底部和升降板之间的水抽出,随后打开半圆板并将接收框取出倒出其内部的絮凝杂质即可,以此能够实现无需将处理筒中的水完全抽出即可取出接收框并倒出絮凝杂质,进而实现对混凝土污水的持续过滤作业。6. The present invention can seal the bottom of the treatment barrel by moving the lifting plate downward, and then use a water pump to pump out the water between the bottom of the treatment barrel and the lifting plate, then open the semicircular plate and take out the receiving frame to pour out the flocculated impurities inside. In this way, it is possible to take out the receiving frame and pour out the flocculated impurities without completely pumping out the water in the treatment barrel, thereby realizing continuous filtration of concrete wastewater.

实施例一:Embodiment 1:

参照图1所示,为了能够对混凝土污水进行过滤净化处理并将过滤后的砂石和水回收利用,本实施例中提供了一种混凝土生产污水综合处理设备,具体的,其包括顶部开口的处理筒1,处理筒1底部侧壁设置有支架2,处理筒1内壁上侧由上到下依次安装有砂块过滤斗3和承接筒4,砂块过滤斗3和承接筒4之间安装有用于对混凝土污水进行多级过滤净化的过滤单元5,过滤单元5包括安装在承接筒4内侧的搅拌组件51,处理筒1中部设置有用于将细砂和石子与水分离的分离单元6。1 , in order to filter and purify concrete wastewater and recycle the filtered sand and water, a comprehensive treatment device for concrete production wastewater is provided in the present embodiment. Specifically, it includes a treatment cylinder 1 with an opening at the top, a bracket 2 is provided on the bottom side wall of the treatment cylinder 1, a sand block filter bucket 3 and a receiving cylinder 4 are installed on the upper side of the inner wall of the treatment cylinder 1 from top to bottom, a filter unit 5 for multi-stage filtration and purification of concrete wastewater is installed between the sand block filter bucket 3 and the receiving cylinder 4, the filter unit 5 includes a stirring assembly 51 installed on the inner side of the receiving cylinder 4, and a separation unit 6 for separating fine sand and gravel from water is provided in the middle of the treatment cylinder 1.

进一步的,于本实施例中,在处理筒1底部通过支架2安装有抽水泵11,抽水泵11的进水端穿过处理筒1后延伸至其内部,抽水泵11的出水端延伸至外部。Furthermore, in this embodiment, a water pump 11 is installed at the bottom of the treatment tube 1 through the bracket 2, the water inlet end of the water pump 11 passes through the treatment tube 1 and extends to the inside thereof, and the water outlet end of the water pump 11 extends to the outside.

在实际应用中,首先将混凝土污水和用于中和其PH值的酸液一同倒入处理筒1内部,其次通过砂块过滤斗3对混凝土污水进行第一次过滤,以便于滤除混凝土污水中直径较大的块状物,期间通过过滤单元5将砂块过滤斗3上端的块状物进行打捞收集,过滤后的混凝土污水进入承接筒4内并在搅拌组件51的作用下对混凝土污水和酸液进行搅拌混合,以中和混凝土污水的碱性;随后混凝土污水向下流落在分离单元6上,以便于对混凝土污水进行第二次过滤,从而清除混凝土污水中的砂石;最后过滤完成的水向下流出至处理筒1底部,启动抽水泵11可以将过滤后的水抽出再次利用,而过滤后的砂石和块状物同样可以回收重复利用,从而能够有效的减少成本、建筑垃圾以及污水排放。In practical applications, first, the concrete sewage and the acid solution for neutralizing its pH value are poured into the treatment barrel 1 together, and then the concrete sewage is filtered for the first time through the sand filter bucket 3 to filter out the lumps with larger diameters in the concrete sewage. During this period, the lumps on the upper end of the sand filter bucket 3 are salvaged and collected by the filter unit 5. The filtered concrete sewage enters the receiving barrel 4 and the concrete sewage and the acid solution are stirred and mixed under the action of the stirring component 51 to neutralize the alkalinity of the concrete sewage; then the concrete sewage flows downwardly and falls on the separation unit 6 to filter the concrete sewage for the second time, thereby removing the sand and gravel in the concrete sewage; finally, the filtered water flows downwardly to the bottom of the treatment barrel 1, and the water pump 11 is started to pump out the filtered water for reuse, and the filtered sand and gravel and lumps can also be recycled and reused, thereby effectively reducing costs, construction waste and sewage discharge.

参照图2所示,为了便于对砂块过滤斗3上端的混凝土污水进行过滤,因此需要确保块状物留存在砂块过滤斗3上端,而混凝土污水穿过砂块过滤斗3后向下流出;基于此,在本实施例中,砂块过滤斗3为中部下沉的锥形筒状,砂块过滤斗3上均匀开设有多个筛分孔52;此外,本实施例中在过滤单元5的基础上做了进一步改进,具体的,过滤单元5还包括通过电机座安装在处理筒1顶部的定位电机53,定位电机53底部的输出轴转动穿设在砂块过滤斗3底部,定位电机53的输出轴底部套设有环形板54,环形板54上设置有用于将砂块过滤斗3上端的块状物收集的收集组件55。As shown in Figure 2, in order to facilitate the filtering of concrete sewage at the upper end of the sand block filter bucket 3, it is necessary to ensure that the lumps remain at the upper end of the sand block filter bucket 3, and the concrete sewage flows downward after passing through the sand block filter bucket 3; based on this, in the present embodiment, the sand block filter bucket 3 is a conical cylinder with a sunken middle part, and a plurality of screening holes 52 are evenly opened on the sand block filter bucket 3; in addition, in the present embodiment, further improvements are made on the basis of the filter unit 5. Specifically, the filter unit 5 also includes a positioning motor 53 installed on the top of the processing cylinder 1 through a motor seat, and the output shaft at the bottom of the positioning motor 53 is rotatably penetrated through the bottom of the sand block filter bucket 3, and the bottom of the output shaft of the positioning motor 53 is sleeved with an annular plate 54, and the annular plate 54 is provided with a collecting component 55 for collecting the lumps at the upper end of the sand block filter bucket 3.

参照图2和图3所示,进一步的,于本实施例中,收集组件55包括多个安装在环形板54下端并环形分布的拨杆551,拨杆551与砂块过滤斗3上端倾斜度相等并且滑动对接在其上端,拨杆551上端沿长度方向等间距设置有多个拨齿552。Referring to Figures 2 and 3, further, in this embodiment, the collecting assembly 55 includes a plurality of levers 551 installed at the lower end of the annular plate 54 and distributed in a ring. The levers 551 have the same inclination as the upper end of the sand filter bucket 3 and are slidably docked at the upper end thereof. A plurality of lever teeth 552 are arranged at equal intervals along the length direction on the upper end of the levers 551.

更进一步的,于本实施例中,在处理筒1上端通过可拆卸的方式对称安装有两个承托杆553,承托杆553底部设置有位于在砂块过滤斗3上端的收集箱554,收集箱554和砂块过滤斗3之间的间距等于拨杆551的厚度,收集箱554下端开设有多个与拨齿552位置相对应的让位槽555,通过设置让位槽555,可以使得环形板54通过拨杆551带动拨齿552周向运动时能够穿过让位槽555,避免收集箱554对拨齿552造成阻挡。Furthermore, in this embodiment, two supporting rods 553 are symmetrically installed at the upper end of the processing cylinder 1 in a detachable manner. A collecting box 554 located at the upper end of the sand block filter bucket 3 is arranged at the bottom of the supporting rod 553. The distance between the collecting box 554 and the sand block filter bucket 3 is equal to the thickness of the lever 551. A plurality of clearance grooves 555 corresponding to the positions of the lever teeth 552 are opened at the lower end of the collecting box 554. By setting the clearance grooves 555, the annular plate 54 can pass through the clearance grooves 555 when the lever teeth 552 are driven to move circumferentially by the lever 551, thereby avoiding the collection box 554 from blocking the lever teeth 552.

在具体实施过程中,启动定位电机53,定位电机53带动环形板54进行转动,环形板54带动拨杆551进行转动,拨杆551带动拨齿552同步运动,以此通过拨杆551配合拨齿552将混凝土污水中直径较大的块状物拨动至收集箱554内,使得收集箱554对块状物进行收集,且收集箱554通过让位槽555可以将其内部的混凝土污水排出,从而实现混凝土污水的第一次过滤,过滤后的混凝土污水经过筛分孔52向下流出至承接筒4内。During the specific implementation process, the positioning motor 53 is started, the positioning motor 53 drives the annular plate 54 to rotate, the annular plate 54 drives the lever 551 to rotate, and the lever 551 drives the shifting tooth 552 to move synchronously, so that the lever 551 cooperates with the shifting tooth 552 to shift the blocks with larger diameters in the concrete sewage into the collecting box 554, so that the collecting box 554 collects the blocks, and the collecting box 554 can discharge the concrete sewage inside through the yield groove 555, thereby realizing the first filtration of the concrete sewage, and the filtered concrete sewage flows downward through the screening hole 52 into the receiving tube 4.

收集箱554中的块状物集满之后,通过承托杆553将收集箱554取下并将其内部的块状物倒出,再将收集箱554重新安装在处理筒1内即可。After the collecting box 554 is full of lumps, the collecting box 554 is removed by the supporting rod 553 and the lumps inside are poured out, and then the collecting box 554 is reinstalled in the processing tube 1.

参照图4所示,为了提高对混凝土污水中块状物的收集速度,所以本实施例中,在环形板54下端均匀安装有多个环形分布的抵触块56,砂块过滤斗3上端靠近其轴线的一侧设置有多个与抵触块56交错排布的定位块57,且抵触块56与定位块57滑移抵接并控制砂块过滤斗3上下振动。4 , in order to increase the collection speed of lumps in concrete sewage, in this embodiment, a plurality of annularly distributed abutment blocks 56 are evenly installed at the lower end of the annular plate 54, and a plurality of positioning blocks 57 staggered with the abutment blocks 56 are arranged on the side of the upper end of the sand filter hopper 3 close to its axis, and the abutment blocks 56 and the positioning blocks 57 are slidably abutted to control the up and down vibration of the sand filter hopper 3.

进一步的,于本实施例中,在砂块过滤斗3上端靠近边缘处与处理筒1内顶壁之间均匀设置有多个环形分布的收缩弹簧杆58以及罩设于多个收缩弹簧杆58内侧的环形伸缩板59,收缩弹簧杆58始终对砂块过滤斗3施加向上的拉力,使得砂块过滤斗3在初始状态下处于最高位置。Furthermore, in this embodiment, a plurality of annularly distributed retractable spring rods 58 and an annular telescopic plate 59 covered on the inner sides of the plurality of retractable spring rods 58 are evenly arranged between the upper end of the sand block filter 3 near the edge and the inner top wall of the processing tube 1. The retractable spring rods 58 always apply an upward pulling force to the sand block filter 3, so that the sand block filter 3 is in the highest position in the initial state.

在具体实施过程中,环形板54转动的过程中带动抵触块56周向运动,当抵触块56与定位块57发生抵触时,定位块57受力带动砂块过滤斗3下移,随后在收缩弹簧杆58的作用下迅速上移复位,以此实现砂块过滤斗3的上下振动;从而通过砂块过滤斗3对混凝土污水进行第一次过滤的同时可以对其进行振动,能够提高对混凝土污水和块状物的筛分效率,且可以将附着在收集箱554侧壁和环形伸缩板59内侧壁的块状物振落,实现块状物的完全收集。During the specific implementation process, the annular plate 54 drives the resistance block 56 to move circumferentially during its rotation. When the resistance block 56 conflicts with the positioning block 57, the positioning block 57 is forced to drive the sand filter bucket 3 to move downward, and then quickly moves upward and reset under the action of the contraction spring rod 58, thereby realizing the up and down vibration of the sand filter bucket 3; thereby, the concrete sewage can be vibrated while being filtered for the first time by the sand filter bucket 3, which can improve the screening efficiency of concrete sewage and lumps, and the lumps attached to the side wall of the collection box 554 and the inner wall of the annular telescopic plate 59 can be shaken off, thereby realizing the complete collection of the lumps.

参照图5所示,为了便于对混凝土污水进行酸碱中和处理,在本实施例中,承接筒4由三部分组成,其中,承接筒4上部分为直径由上到下逐渐减小的锥形筒状,承接筒4的中部为直径相等的圆柱筒状,且承接筒4的下部分的直径由上到下逐渐增大。5 , in order to facilitate the acid-base neutralization treatment of concrete wastewater, in this embodiment, the receiving tube 4 is composed of three parts, wherein the upper part of the receiving tube 4 is a conical tube with a diameter gradually decreasing from top to bottom, the middle part of the receiving tube 4 is a cylindrical tube with an equal diameter, and the diameter of the lower part of the receiving tube 4 gradually increases from top to bottom.

参照图5和图6所示,为了增强对混凝土污水的中和效果,需要将混凝土污水与酸液之间进行充分混合均匀,基于此,在本实施例中,搅拌组件51包括安装在定位电机53输出轴下端的支撑轴511,支撑轴511底部转动套设有与承接筒4中部内壁相连接的支撑架512,支撑轴511外壁由上到下等间距套设有多个位于承接筒4上部分的套筒513,套筒513侧壁设置有多个环形分布的执行杆514。5 and 6 , in order to enhance the neutralization effect on concrete sewage, it is necessary to fully and evenly mix the concrete sewage and the acid solution. Based on this, in the present embodiment, the stirring assembly 51 includes a support shaft 511 installed at the lower end of the output shaft of the positioning motor 53, and a support frame 512 connected to the inner wall of the middle part of the receiving tube 4 is rotatably sleeved on the bottom of the support shaft 511. A plurality of sleeves 513 located on the upper part of the receiving tube 4 are sleeved on the outer wall of the support shaft 511 at equal intervals from top to bottom, and a plurality of annularly distributed actuator rods 514 are arranged on the side wall of the sleeve 513.

进一步的,于本实施例中,支撑轴511下端设置有双向螺杆515,双向螺杆515底部转动套设有与承接筒4下部分内壁相连接的连接架516,支撑架512和连接架516的相对侧沿双向螺杆515对称设置有两个导向板517,双向螺杆515外壁通过螺纹连接的方式套设有圆形板518,圆形板518的直径与承接筒4中部内径相等,以便于对承接筒4进行封闭,且圆形板518滑动套设在两个导向板517外壁,通过导向板517可以对圆形板518进行限位,使得圆形板518只能上下移动,无法转动;需要说明的是,双向螺杆515外壁设置有两组旋向相反且相互连通的的传动螺纹,圆形板518内侧壁安装有与传动螺纹滑动连接的滚珠(图中为示出),当圆形板518沿双向螺杆515的任一传动螺纹移动至其顶部或底部时,在圆形板518可以带动滚珠与另一个传动螺纹相抵接,以此控制圆形板518沿另一个传动螺纹移动,从而在双向螺杆515转动时可以带动圆形板518上下往复移动。Furthermore, in this embodiment, a bidirectional screw 515 is provided at the lower end of the support shaft 511, and a connecting frame 516 connected to the inner wall of the lower part of the receiving tube 4 is rotatably sleeved at the bottom of the bidirectional screw 515, and two guide plates 517 are symmetrically provided along the bidirectional screw 515 on the opposite sides of the support frame 512 and the connecting frame 516. A circular plate 518 is sleeved on the outer wall of the bidirectional screw 515 by threaded connection. The diameter of the circular plate 518 is equal to the inner diameter of the middle part of the receiving tube 4, so as to close the receiving tube 4, and the circular plate 518 is slidably sleeved on the outer walls of the two guide plates 517, and the circular plates 518 can be adjusted by the guide plates 517. 18 is limited so that the circular plate 518 can only move up and down but cannot rotate; it should be noted that the outer wall of the bidirectional screw 515 is provided with two sets of transmission threads with opposite rotation directions and interconnected, and the inner wall of the circular plate 518 is installed with balls slidably connected to the transmission threads (shown in the figure). When the circular plate 518 moves along any transmission thread of the bidirectional screw 515 to its top or bottom, the circular plate 518 can drive the balls to abut against the other transmission thread, thereby controlling the circular plate 518 to move along the other transmission thread, so that when the bidirectional screw 515 rotates, the circular plate 518 can be driven to reciprocate up and down.

在具体实施过程中,经过砂块过滤斗3过滤后的混凝土污水向下流入承接筒4内,此时定位电机53的输出轴带动支撑轴511进行转动,支撑轴511通过套筒513带动执行杆514同步转动并对承接筒4内部的混凝土污水和酸液进行搅拌,以便于对混凝土污水进行酸碱中和处理。During the specific implementation process, the concrete sewage filtered by the sand filter 3 flows downward into the receiving tube 4. At this time, the output shaft of the positioning motor 53 drives the support shaft 511 to rotate, and the support shaft 511 drives the actuator rod 514 to rotate synchronously through the sleeve 513 and stir the concrete sewage and acid liquid inside the receiving tube 4 to facilitate acid-base neutralization treatment of the concrete sewage.

在此期间,支撑轴511带动双向螺杆515同步转动,双向螺杆515转动的同时带动圆形板518上下往复移动,且圆形板518缓慢移动,当圆形板518位于承接筒4的中部时可以对其进行封闭,使其上端的混凝土污水和酸液具有充足的混合时间,以此增强对混凝土污水的中和效果;随后圆形板518向下移动至承接筒4的下部分并解除对其中部的封闭效果,此时承接筒4内部的混凝土污水向下流出至分离单元6内;以此重复上述步骤即可实现对混凝土污水的酸碱中和处理,避免过滤后的混凝土污水具有强碱性而无法使用或排放。During this period, the support shaft 511 drives the bidirectional screw 515 to rotate synchronously. While the bidirectional screw 515 rotates, it drives the circular plate 518 to move back and forth up and down, and the circular plate 518 moves slowly. When the circular plate 518 is located in the middle of the receiving tube 4, it can be closed so that the concrete sewage and acid liquid at its upper end have sufficient mixing time, thereby enhancing the neutralization effect on the concrete sewage; then the circular plate 518 moves downward to the lower part of the receiving tube 4 and releases the sealing effect on the middle part thereof. At this time, the concrete sewage inside the receiving tube 4 flows downward into the separation unit 6; by repeating the above steps, the acid-base neutralization treatment of the concrete sewage can be achieved, thereby avoiding the filtered concrete sewage having strong alkalinity and being unable to be used or discharged.

参照图7所示,由于混凝土污水在第一次过滤和酸碱中和处理之后,其内部仍然含有颗粒较小的砂石,为了进一步对砂石进行过滤,本实施例中还设置了分离单元6,具体的,分离单元6包括位于承接筒4下方的过滤垫61,分离单元6包括固定板62,处理筒1外侧壁沿承接筒4对称安装有两个定位组,每个定位组包括两个沿承接筒4对称排布的固定板62,处理筒1同一侧的两个固定板62之间转动设置有转轴63,任一固定板62侧壁通过电机罩设置有与该固定板62上转轴63相连接的驱动电机64,过滤垫61为传送带结构并穿过处理筒1后套设在两个转轴63外壁,处理筒1上开设有用于穿过过滤垫61的通孔。As shown in Figure 7, since the concrete sewage still contains smaller particles of sand and gravel after the first filtration and acid-base neutralization treatment, in order to further filter the sand and gravel, a separation unit 6 is also provided in this embodiment. Specifically, the separation unit 6 includes a filter pad 61 located below the receiving tube 4, and the separation unit 6 includes a fixed plate 62. Two positioning groups are symmetrically installed on the outer wall of the treatment tube 1 along the receiving tube 4, and each positioning group includes two fixed plates 62 symmetrically arranged along the receiving tube 4. A rotating shaft 63 is rotatably arranged between the two fixed plates 62 on the same side of the treatment tube 1. A driving motor 64 connected to the rotating shaft 63 on the fixed plate 62 is provided on the side wall of any fixed plate 62 through a motor cover. The filter pad 61 is a conveyor belt structure and is sleeved on the outer walls of the two rotating shafts 63 after passing through the treatment tube 1. A through hole for passing the filter pad 61 is opened on the treatment tube 1.

进一步的,于本实施例中,在过滤垫61上均匀开设有多个过滤孔65,且过滤垫61外侧壁沿其宽度方向对称设置有两个柔性挡板66,过滤垫61外侧壁位于两个柔性挡板66之间等间距安装有多个收集斗67;处理筒1内侧壁沿过滤垫61对称设置有两个位于过滤垫61上端的定位轴611,定位轴611端部未与柔性挡板66相接触,且处理筒1内侧壁安装有与过滤垫61宽度方向相平行的压轴612,压轴612位于过滤垫61下半部的上端。Furthermore, in this embodiment, a plurality of filter holes 65 are evenly arranged on the filter pad 61, and two flexible baffles 66 are symmetrically arranged on the outer wall of the filter pad 61 along its width direction, and a plurality of collecting buckets 67 are installed at equal intervals on the outer wall of the filter pad 61 between the two flexible baffles 66; two positioning shafts 611 located at the upper end of the filter pad 61 are symmetrically arranged on the inner wall of the processing cylinder 1 along the filter pad 61, and the end of the positioning shaft 611 does not contact the flexible baffle 66, and a pressing shaft 612 parallel to the width direction of the filter pad 61 is installed on the inner wall of the processing cylinder 1, and the pressing shaft 612 is located at the upper end of the lower half of the filter pad 61.

更进一步的,为了避免过滤垫61上端的水和砂石经过通孔渗出至处理筒1外部,因此在本实施例中,定位轴611和压轴612之间的距离等于过滤垫61上下两部分之间的距离,且定位轴611和压轴612的高度低于转轴63的高度,用于将过滤垫61的中部下压,使得过滤垫61为V形结构,当过滤垫61的中部向处理筒1外侧运动时,其同时向上倾斜,此时过滤垫61上残留的水可以滴落,避免过滤垫61将水带出至处理筒1外部而影响外部环境。Furthermore, in order to prevent water and sand from seeping out of the treatment tube 1 from the upper end of the filter pad 61 through the through hole, in the present embodiment, the distance between the positioning shaft 611 and the pressing shaft 612 is equal to the distance between the upper and lower parts of the filter pad 61, and the heights of the positioning shaft 611 and the pressing shaft 612 are lower than the height of the rotating shaft 63, which are used to press down the middle part of the filter pad 61 so that the filter pad 61 has a V-shaped structure. When the middle part of the filter pad 61 moves toward the outside of the treatment tube 1, it tilts upward at the same time. At this time, the residual water on the filter pad 61 can drip, so as to prevent the filter pad 61 from bringing water out of the treatment tube 1 and affecting the external environment.

在具体实施过程中,启动驱动电机64,驱动电机64通过转轴63带动过滤垫61周向运动,期间通过定位轴611和压轴612可以对过滤垫61进行限位,使得过滤垫61始终保持V形结构且中部下沉;当承接筒4内部的混凝土污水向下流出至过滤垫61上时,通过过滤垫61能够对混凝土污水进行第二次过滤,以便于滤除混凝土污水中直径较小的砂石,过滤后的水经过过滤孔65向下流出,且砂石留存在过滤垫61上端。During the specific implementation process, the driving motor 64 is started, and the driving motor 64 drives the filter pad 61 to move circumferentially through the rotating shaft 63. During this period, the filter pad 61 can be limited by the positioning shaft 611 and the pressing shaft 612, so that the filter pad 61 always maintains a V-shaped structure and the middle part sinks; when the concrete sewage inside the receiving tube 4 flows downward onto the filter pad 61, the concrete sewage can be filtered for a second time through the filter pad 61, so as to filter out the sand and gravel with smaller diameters in the concrete sewage, and the filtered water flows downward through the filter hole 65, and the sand and gravel remain at the upper end of the filter pad 61.

随后过滤垫61继续周向运动,在过滤垫61的中部向处理筒1外侧运动的同时向上运动,此时过滤垫61处于倾斜状态,因此过滤垫61上端的砂石在重力作用下滚落在收集斗67中,随后过滤垫61通过收集斗67将砂石带出至处理筒1外部,且在过滤垫61的顶部运动至转轴63下方时,收集斗67向下翻转,此时收集斗67中的砂石能够自然掉落,以此完成对混凝土污水的第二次过滤,且能够实现砂石和水之间的分离。Then the filter pad 61 continues to move in a circumferential direction, and moves upward while the middle part of the filter pad 61 moves toward the outside of the treatment tube 1. At this time, the filter pad 61 is in an inclined state, so the sand and gravel on the upper end of the filter pad 61 rolls into the collecting bucket 67 under the action of gravity. Then the filter pad 61 brings the sand and gravel out of the treatment tube 1 through the collecting bucket 67, and when the top of the filter pad 61 moves to below the rotating shaft 63, the collecting bucket 67 flips downward. At this time, the sand and gravel in the collecting bucket 67 can fall naturally, thereby completing the second filtration of the concrete sewage and realizing the separation between sand and gravel and water.

实施例二:Embodiment 2:

参照图8所示,在实施例一的基础上,为了进一步提高对水的过滤效果,本实施例中在对混凝土污水的酸碱中和过程中添加絮凝剂,从而对混凝土污水搅拌之后,其内部的细小灰尘和杂质组成的絮凝杂质会发生沉淀,而通过过滤垫61难以将絮凝杂质完全滤除;基于此,于本实施例中,在处理筒1底部设置有两个可开合的半圆板12,半圆板12和处理筒1之间相铰接,两个半圆板12上端可拆卸的设置有接收框13,接收框13上端滑动插接在处理筒1内侧壁,且抽水泵11的进水端位于接收框13和处理筒1之间。As shown in Figure 8, on the basis of Example 1, in order to further improve the filtering effect of water, in this embodiment, a flocculant is added during the acid-base neutralization process of the concrete sewage, so that after the concrete sewage is stirred, the flocculated impurities composed of fine dust and impurities inside it will precipitate, and it is difficult to completely filter out the flocculated impurities through the filter pad 61; based on this, in this embodiment, two openable and closable semicircular plates 12 are provided at the bottom of the treatment cylinder 1, and the semicircular plates 12 and the treatment cylinder 1 are hinged, and the upper ends of the two semicircular plates 12 are detachably provided with receiving frames 13, and the upper ends of the receiving frames 13 are slidably inserted into the inner wall of the treatment cylinder 1, and the water inlet end of the water pump 11 is located between the receiving frame 13 and the treatment cylinder 1.

在具体实施过程中,通过接收框13用于承接回收沉淀的絮凝杂质,抽水泵11将过滤完成的水抽出时,接收框13中的絮凝杂质无法被抽出,抽水泵11将处理筒1中过滤完成的水完全抽出之后,打开半圆板12,再将接收框13取下即可将絮凝杂质倒出;随后将接收框13和半圆板12重新复位即可。In the specific implementation process, the receiving frame 13 is used to receive and recover the precipitated flocculated impurities. When the water pump 11 pumps out the filtered water, the flocculated impurities in the receiving frame 13 cannot be pumped out. After the water pump 11 completely pumps out the filtered water in the treatment cylinder 1, the semicircular plate 12 is opened, and the receiving frame 13 is removed to pour out the flocculated impurities; then the receiving frame 13 and the semicircular plate 12 can be reset.

实施例三:Embodiment three:

参照图9、图10和图11所示,在实施例二的基础上,由于接收框13只能容纳一定量的絮凝杂质,且需要在处理筒1中的水完全抽出之后才能取出接收框13,因此为了能够对混凝土污水进行持续过滤作业,即无需将处理筒1中的水抽完也能取出接收框13并将絮凝杂质倒出,在本实施例中还设置了二次分离单元7,该二次分离单元7具体内容如下:9, 10 and 11, on the basis of the second embodiment, since the receiving frame 13 can only accommodate a certain amount of flocculated impurities, and the receiving frame 13 can be taken out only after the water in the treatment barrel 1 is completely pumped out, in order to be able to perform continuous filtering operations on concrete sewage, that is, the receiving frame 13 can be taken out and the flocculated impurities can be poured out without completely pumping out the water in the treatment barrel 1, a secondary separation unit 7 is further provided in this embodiment, and the specific contents of the secondary separation unit 7 are as follows:

处理筒1内侧壁安装有位于过滤垫61下方的安装架71,安装架71下端通过防水气缸72设置有升降板73,升降板73上开设有多个冒水孔74,升降板73内部开设有多个与冒水孔74位置相对应且相互连通的容纳槽75,容纳槽75内部滑动连接有挡水板76,挡水板76的直径大于冒水孔74的内径,且挡水板76和容纳槽75上下两侧内壁之间紧密贴合。A mounting frame 71 located below the filter pad 61 is installed on the inner wall of the treatment cylinder 1, and a lifting plate 73 is provided at the lower end of the mounting frame 71 through a waterproof cylinder 72. A plurality of water holes 74 are provided on the lifting plate 73. A plurality of receiving grooves 75 corresponding to the positions of the water holes 74 and interconnected are provided inside the lifting plate 73. A water retaining plate 76 is slidably connected inside the receiving groove 75. The diameter of the water retaining plate 76 is larger than the inner diameter of the water holes 74, and the water retaining plate 76 and the upper and lower inner walls of the receiving groove 75 fit tightly.

进一步的,于本实施例中,在升降板73内部滑动穿设有多个连接杆77,连接杆77穿过同一行的多个挡水板76,且连接杆77一端穿过升降板73后延伸至外部,另一端滑动对接在开设于升降板73内部的凹槽内,连接杆77端部和凹槽之间安装有复位弹簧78;复位弹簧78始终对连接杆77施加推挤力,使得连接杆77在初始状态下带动挡水板76始终抵靠在容纳槽75一侧,此时挡水板76不与冒水孔74重合,且连接杆77远离复位弹簧78的一端从升降板73内伸出。Furthermore, in this embodiment, a plurality of connecting rods 77 are slidably penetrated inside the lifting plate 73, the connecting rods 77 pass through a plurality of water baffles 76 in the same row, and one end of the connecting rod 77 passes through the lifting plate 73 and extends to the outside, and the other end is slidably docked in a groove opened inside the lifting plate 73, and a reset spring 78 is installed between the end of the connecting rod 77 and the groove; the reset spring 78 always applies a pushing force to the connecting rod 77, so that the connecting rod 77 drives the water baffle 76 to always rest against one side of the accommodating groove 75 in the initial state, at which time the water baffle 76 does not overlap with the water emitting hole 74, and the end of the connecting rod 77 away from the reset spring 78 extends out from the lifting plate 73.

更进一步的,为了便于连接杆77自动收回至凹槽内部并带动挡水板76对冒水孔74进行封闭,在本实施例中,处理筒1底部的直径由上到下逐渐减小,处理筒1内侧壁安装有位于升降板73下方的顶块79,顶块79位于连接杆77伸出的一侧,顶块79上端逐渐向靠近处理筒1轴线的一侧倾斜,且顶块79底部靠近处理筒1轴线的一侧设置有用于承接升降板73的延伸段,升降板73靠近顶块79的一侧为让位面,当升降板73下降时,让位面可以与顶块79靠近处理筒1轴线的一侧滑动抵接。Furthermore, in order to facilitate the automatic retraction of the connecting rod 77 into the groove and drive the water baffle plate 76 to close the water hole 74, in the present embodiment, the diameter of the bottom of the treatment cylinder 1 gradually decreases from top to bottom, and the inner wall of the treatment cylinder 1 is provided with a top block 79 located below the lifting plate 73, the top block 79 is located on the side where the connecting rod 77 extends, the upper end of the top block 79 gradually tilts toward the side close to the axis of the treatment cylinder 1, and an extension section for receiving the lifting plate 73 is provided on the side of the bottom of the top block 79 close to the axis of the treatment cylinder 1, and the side of the lifting plate 73 close to the top block 79 is a yield surface, and when the lifting plate 73 descends, the yield surface can slide and abut against the side of the top block 79 close to the axis of the treatment cylinder 1.

此外,为了确保水和絮凝杂质之间的有效分离,需要防止升降板73下降之后与顶块79和处理筒1之间存在缝隙,因此,本实施例中,在升降板73外侧壁套设有用于补偿缝隙的橡胶圈70。In addition, in order to ensure effective separation between water and flocculated impurities, it is necessary to prevent a gap from forming between the lifting plate 73 and the top block 79 and the treatment cylinder 1 after the lifting plate 73 is lowered. Therefore, in this embodiment, a rubber ring 70 for compensating the gap is provided on the outer wall of the lifting plate 73.

在具体实施过程中,启动防水气缸72,防水气缸72带动升降板73及其内部的挡水板76和连接杆77整体向下移动,当连接杆77的端部于顶块79上端发生接触时受到推挤力并带动挡水板76向靠近凹槽的一侧移动,此时处理筒1底部的水从冒水孔74向上溢出,而沉淀在接收框13内的絮凝杂质不会受到影响。During the specific implementation process, the waterproof cylinder 72 is started, and the waterproof cylinder 72 drives the lifting plate 73 and the water baffle 76 and connecting rod 77 inside it to move downward as a whole. When the end of the connecting rod 77 contacts the upper end of the top block 79, it is subjected to a pushing force and drives the water baffle 76 to move to the side close to the groove. At this time, the water at the bottom of the treatment cylinder 1 overflows upward from the water hole 74, and the flocculated impurities deposited in the receiving frame 13 will not be affected.

当升降板73底部与顶块79的延伸段发生抵触时,升降板73下移至最低位置,此时连接杆77在顶块79的作用下带动挡水板76对冒水孔74进行密封,此时启动抽水泵11,抽水泵11将处理筒1底部和升降板73之间的水抽出,且升降板73上方的水无法向下流出;随后打开半圆板12并将接收框13取出倒出其内部的絮凝杂质即可,从而可以防止抽出过滤后净水时引起絮凝杂质在水中扬起而导致净水出现浑浊的情况,此时过滤单元5和分离单元6可以持续进行对混凝土污水的过滤处理且不受影响;以此能够对混凝土污水进行再次分离,以便于去除水中的絮凝杂质,从而确保过滤后水中不含有杂质且能够重新回收利用,进而减少水资源的浪费,且可以有效避免直接排放混凝土污水而污染环境。When the bottom of the lifting plate 73 collides with the extended section of the top block 79, the lifting plate 73 moves down to the lowest position. At this time, the connecting rod 77 drives the water retaining plate 76 to seal the water emitting hole 74 under the action of the top block 79. At this time, the water pump 11 is started, and the water pump 11 pumps out the water between the bottom of the treatment cylinder 1 and the lifting plate 73, and the water above the lifting plate 73 cannot flow downward; then the semicircular plate 12 is opened and the receiving frame 13 is taken out to pour out the flocculated impurities inside it, thereby preventing the flocculated impurities from being raised in the water when the filtered clean water is extracted, causing the clean water to become turbid. At this time, the filtering unit 5 and the separating unit 6 can continue to filter the concrete sewage without being affected; in this way, the concrete sewage can be separated again to remove the flocculated impurities in the water, thereby ensuring that the filtered water does not contain impurities and can be recycled, thereby reducing the waste of water resources and effectively avoiding the direct discharge of concrete sewage to pollute the environment.

需要说明的是,处理筒1底部设置有与外界相连通的泄压单向阀,泄压单向阀只能使外部的空气进入处理筒1,无法使处理筒1中的水排出,其主要作用为抽水泵11将处理筒1底部的水抽出时,处理筒1底部容易出现负压,此时通过泄压单向阀可以从外部吸入空气,使得处理筒1内部的气压稳定,不会发生抽水泵11无法正常工作的现象。It should be noted that a pressure relief one-way valve connected to the outside world is arranged at the bottom of the treatment cylinder 1. The pressure relief one-way valve can only allow external air to enter the treatment cylinder 1, but cannot discharge the water in the treatment cylinder 1. Its main function is that when the water pump 11 pumps out the water at the bottom of the treatment cylinder 1, negative pressure is likely to appear at the bottom of the treatment cylinder 1. At this time, air can be sucked in from the outside through the pressure relief one-way valve, so that the air pressure inside the treatment cylinder 1 is stable, and the water pump 11 will not fail to work normally.

接收框13内的絮凝杂质倒出并安装复位之后,防水气缸72带动升降板73向上移动复位,此时连接杆77在复位弹簧78的作用下复位,且处理筒1上部分的水和絮凝杂质均向下流落至处理筒1底部;随后重复上述步骤能够实现无需将处理筒1中的水完全抽出即可取出接收框13并倒出絮凝杂质,以此可以实现对混凝土污水的持续过滤作业。After the flocculated impurities in the receiving frame 13 are poured out and installed and reset, the waterproof cylinder 72 drives the lifting plate 73 to move upward and reset. At this time, the connecting rod 77 is reset under the action of the reset spring 78, and the water and flocculated impurities in the upper part of the treatment cylinder 1 all flow down to the bottom of the treatment cylinder 1; then repeating the above steps can achieve the need to completely extract the water in the treatment cylinder 1 to remove the receiving frame 13 and pour out the flocculated impurities, thereby realizing the continuous filtration operation of concrete sewage.

此外,本发明还提供了一种混凝土生产污水综合处理工艺,包括以下步骤:In addition, the present invention also provides a comprehensive treatment process for concrete production wastewater, comprising the following steps:

S1、污水倒入:首先将混凝土污水、用于中和其PH值的酸液和絮凝剂一同倒入处理筒1内部,使得混凝土污水流落在砂块过滤斗3上端。S1. Sewage pouring: First, pour the concrete sewage, the acid solution for neutralizing its pH value and the flocculant into the treatment cylinder 1 together, so that the concrete sewage flows into the upper end of the sand filter hopper 3.

S2、污水过滤:通过砂块过滤斗3滤除混凝土污水中直径较大的块状物,启动定位电机53,定位电机53带动环形板54、拨杆551和拨齿552整体周向运动,通过拨杆551配合拨齿552将混凝土污水中直径较大的块状物拨动至收集箱554内,使得收集箱554对块状物进行收集,从而实现混凝土污水的第一次过滤,过滤后的混凝土污水经过筛分孔52向下流出至承接筒4内。S2, sewage filtration: The blocks with larger diameters in the concrete sewage are filtered out through the sand block filter 3, and the positioning motor 53 is started. The positioning motor 53 drives the annular plate 54, the lever 551 and the lever teeth 552 to move circumferentially as a whole. The lever 551 cooperates with the lever teeth 552 to move the blocks with larger diameters in the concrete sewage into the collection box 554, so that the collection box 554 collects the blocks, thereby realizing the first filtration of the concrete sewage. The filtered concrete sewage flows downward through the screening holes 52 into the receiving tube 4.

与此同时,通过抵触块56配合定位块57可以对砂块过滤斗3施加振动效果,以加快对混凝土污水和块状物的筛分,且可以将附着在收集箱554侧壁和环形伸缩板59内侧壁的块状物振落,实现块状物的完全收集。At the same time, the friction block 56 and the positioning block 57 can be used to apply a vibration effect to the sand filter hopper 3 to speed up the screening of concrete sewage and lumps, and the lumps attached to the side wall of the collection box 554 and the inner wall of the annular telescopic plate 59 can be shaken off to achieve complete collection of the lumps.

收集箱554中的块状物集满之后,通过承托杆553将收集箱554取下并将其内部的块状物倒出,再将收集箱554重新安装在处理筒1内即可。After the collecting box 554 is full of lumps, the collecting box 554 is removed by the supporting rod 553 and the lumps inside are poured out, and then the collecting box 554 is reinstalled in the processing tube 1.

S3、污水中和:经过砂块过滤斗3过滤后的混凝土污水向下流入承接筒4内,此时定位电机53的输出轴带动支撑轴511进行转动,支撑轴511通过套筒513带动执行杆514同步转动并对承接筒4内部的混凝土污水和酸液进行搅拌,以便于对混凝土污水进行酸碱中和处理。S3, sewage neutralization: the concrete sewage filtered by the sand filter 3 flows downward into the receiving tube 4. At this time, the output shaft of the positioning motor 53 drives the support shaft 511 to rotate, and the support shaft 511 drives the actuator rod 514 to rotate synchronously through the sleeve 513 and stir the concrete sewage and acid solution inside the receiving tube 4, so as to facilitate the acid-base neutralization treatment of the concrete sewage.

在此期间,支撑轴511带动双向螺杆515同步转动,双向螺杆515转动的同时带动圆形板518上下缓慢往复移动,当圆形板518位于承接筒4的中部时可以对其进行封闭,使其上端的混凝土污水和酸液具有充足的混合时间;随后圆形板518向下移动至承接筒4的下部分可以使其内部的混凝土污水向下流出。During this period, the support shaft 511 drives the bidirectional screw 515 to rotate synchronously. While the bidirectional screw 515 rotates, it drives the circular plate 518 to move slowly back and forth up and down. When the circular plate 518 is located in the middle of the receiving tube 4, it can be closed so that the concrete sewage and acid liquid at its upper end have sufficient mixing time; then the circular plate 518 moves downward to the lower part of the receiving tube 4 so that the concrete sewage inside can flow out downward.

S4、污水二次过滤:启动驱动电机64,驱动电机64通过转轴63带动过滤垫61周向运动,当承接筒4内部的混凝土污水向下流出至过滤垫61上时,通过过滤垫61能够对混凝土污水进行第二次过滤,以便于滤除混凝土污水中直径较小的砂石,过滤后的水经过过滤孔65向下流出,且砂石留存在过滤垫61上端;在此期间,过滤垫61通过收集斗67将砂石带出至处理筒1外部,以此完成对混凝土污水的第二次过滤,且能够实现砂石和水之间的分离。S4, secondary filtration of sewage: start the driving motor 64, and the driving motor 64 drives the filter pad 61 to move circumferentially through the rotating shaft 63. When the concrete sewage inside the receiving tube 4 flows downward to the filter pad 61, the filter pad 61 can filter the concrete sewage for the second time, so as to filter out the sand and gravel with smaller diameters in the concrete sewage. The filtered water flows downward through the filter hole 65, and the sand and gravel remain on the upper end of the filter pad 61; during this period, the filter pad 61 brings the sand and gravel out to the outside of the treatment tube 1 through the collecting bucket 67, thereby completing the second filtration of the concrete sewage and realizing the separation of sand and gravel from water.

S5、净水排出:过滤完成的净水向下流出至处理筒1底部,启动抽水泵11可以将过滤后的水抽出再次利用,而过滤后的砂石和块状物同样可以回收重复利用,从而能够有效的减少成本、建筑垃圾以及污水排放。S5. Clean water discharge: The clean water after filtration flows downward to the bottom of the treatment tube 1. The water pump 11 is started to extract the filtered water for reuse, and the filtered sand and blocks can also be recycled and reused, thereby effectively reducing costs, construction waste and sewage discharge.

此外,本发明中还提供了用于对混凝土污水进一步过滤净化的技术方案,其工作步骤如下:In addition, the present invention also provides a technical solution for further filtering and purifying concrete wastewater, and its working steps are as follows:

在混凝土污水的酸碱中和过程中添加絮凝剂,通过接收框13用于承接回收沉淀的絮凝杂质,随后启动防水气缸72,防水气缸72带动升降板73及其内部的挡水板76和连接杆77整体向下移动,当连接杆77的端部于顶块79上端发生接触时受到推挤力并带动挡水板76向靠近凹槽的一侧移动,此时处理筒1底部的水从冒水孔74向上溢出,而沉淀在接收框13内的絮凝杂质不会受到影响。During the acid-base neutralization process of concrete sewage, flocculants are added, and the receiving frame 13 is used to receive and recover the precipitated flocculated impurities. Then the waterproof cylinder 72 is started, and the waterproof cylinder 72 drives the lifting plate 73 and the water baffle 76 and connecting rod 77 inside it to move downward as a whole. When the end of the connecting rod 77 contacts the upper end of the top block 79, it is pushed and drives the water baffle 76 to move to the side close to the groove. At this time, the water at the bottom of the treatment cylinder 1 overflows upward from the water outlet 74, and the flocculated impurities precipitated in the receiving frame 13 will not be affected.

当升降板73下移至最低位置,连接杆77在顶块79的作用下带动挡水板76对冒水孔74进行密封,此时启动抽水泵11,抽水泵11将处理筒1底部和升降板73之间的水抽出;随后打开半圆板12并将接收框13取出倒出其内部的絮凝杂质即可。When the lifting plate 73 moves down to the lowest position, the connecting rod 77 drives the water baffle plate 76 to seal the water hole 74 under the action of the top block 79. At this time, the water pump 11 is started to pump out the water between the bottom of the treatment cylinder 1 and the lifting plate 73; then the semicircular plate 12 is opened and the receiving frame 13 is taken out to pour out the flocculated impurities inside.

接收框13内的絮凝杂质倒出并安装复位之后,防水气缸72带动升降板73向上移动复位,此时连接杆77在复位弹簧78的作用下复位,且处理筒1上部分的水和絮凝杂质均向下流落至处理筒1底部;随后重复上述步骤能够实现无需将处理筒1中的水完全抽出即可取出接收框13并倒出絮凝杂质,以此可以实现对混凝土污水的持续过滤作业。After the flocculated impurities in the receiving frame 13 are poured out and installed and reset, the waterproof cylinder 72 drives the lifting plate 73 to move upward and reset. At this time, the connecting rod 77 is reset under the action of the reset spring 78, and the water and flocculated impurities in the upper part of the treatment cylinder 1 all flow down to the bottom of the treatment cylinder 1; then repeating the above steps can achieve the need to completely extract the water in the treatment cylinder 1 to remove the receiving frame 13 and pour out the flocculated impurities, thereby realizing the continuous filtration operation of concrete sewage.
