技术领域
本申请涉及喷涂设备技术领域,具体而言,涉及一种输料过渡机构、泵送装置及喷涂设备。
背景技术
随着技术发展,建筑行业逐渐由人工施工向机械化、自动化转变,如在抹灰施工中,已有喷涂设备代替人工喷涂。喷涂设备一般设有泵送装置和喷枪,通过泵送装置将浆料输出至喷枪,并通过喷枪喷涂在工作面上,喷枪的喷浆速度与喷枪的移动速度必须匹配。现有泵送装置一般采用螺杆泵,螺杆泵的特点是供料稳定均匀,但是输出流量较低,喷枪只能以较低速度移动以匹配喷浆速度。为提高出浆效率,也有考虑采用输出流量较大的柱塞泵,但柱塞泵只能间歇出浆,喷枪无法连续作业,且出浆不稳定,不便控制,容易造成一些区域喷涂过多,而一些区域完全没有浆料。喷涂设备的喷涂连续性和较大的输出流量不能兼顾,要保证喷涂连续就只能采用小流量的连续性泵送装置,喷涂速度较慢,导致整体工作效率较低。
为了保证泵送装置出料均匀、出料量大且连续,在泵送装置和喷枪之间还设有能够缓存浆料的过渡装置,过渡装置包括缓存腔和设置在缓存腔中的弹性储能件,缓存腔的入料口、出料口均与活塞相对,浆料从入料口进入缓存腔并推动弹性储能件实现储存弹性势能,弹性储能件释放弹性势能时将浆料从缓存腔的出料口推出。弹性储能将在推动浆料至出料口时,浆料在入料口处受阻,导致入料口处容易堆积浆料中的骨料,堆积的骨料会进一步阻碍浆料输出,进而导致浆料离析(较大颗粒与水、较小颗粒较小分离)产生堆积更多的骨料的连锁反应,因此堵塞、离析的问题难以缓解。

实施例
随着技术发展,建筑行业逐渐由人工施工向机械化、自动化转变,如在建筑内墙或地面的抹灰作业中,目前一般是人工完成,但现在逐渐开始采用喷涂设备代替人工向工作面喷洒涂料。
喷涂设备一般设有泵送装置和喷枪,通过泵送装置将浆料输出至喷枪,并通过喷枪喷涂在工作面上,喷枪的喷浆速度与喷枪的移动速度必须匹配。现有泵送装置一般采用螺杆泵,螺杆泵的特点是供料稳定均匀,但是输出流量较低,极限情况下只能进行30L/min左右的流量输出,这导致喷浆速度慢,喷枪的移动速度也随之减慢,工作效率较低。为提高工作效率,考虑采用柱塞泵。柱塞泵的输出流量较大,能够实现70L/min的流量输出,但柱塞泵受其泵送方式限制,只能先抽浆再出浆,脉冲式地间歇性的供料,并且柱塞泵在出浆时,泵浆压力非常大,而在抽浆时压力几乎为零,这样的一种大压力差的脉冲式的浆料输出形式,应用于喷浆过程,几乎是不可以控制,无法将喷枪的喷浆速度与喷枪的移动速度匹配,不能实现有效地喷涂作业。鉴于此,本申请提供下述方案:在泵送装置和喷枪之间设置一个输料过渡机构,输料过渡机构接收泵送装置每次脉冲输出的浆料,输料过渡机构中设置弹性储能件,在接收浆料时,弹性储能件将泵浆压力产生的机械能转化为弹性势能储存起来,在泵浆压力消失时,弹性储能件释放弹性势能,以将浆料连续、稳定地输出至喷枪,进而实现大流量地、连续地、稳定地喷涂,使得喷枪的喷浆速度提高,不需通过降低喷枪的移动速度来匹配喷浆速度,从而至少提高了工作效率。
另一方面,为了保证泵送装置出料均匀、出料量大且连续,在泵送装置和喷枪之间还设有能够缓存浆料的过渡装置,过渡装置包括缓存腔和设置在缓存腔中的弹性储能件,缓存腔的入料口、出料口均与活塞相对,浆料从入料口进入缓存腔并推动弹性储能件实现储存弹性势能,弹性储能件释放弹性势能时将浆料从缓存腔的出料口推出。弹性储能件在推动浆料至出料口时,容易在入料口处挤压浆料,导致入料口处容易堆积浆料中的骨料,堆积的骨料会进一步阻碍浆料输出,进而导致浆料离析(较大颗粒与水、较小颗粒较小分离)产生堆积更多的骨料的连锁反应,因此堵塞、离析的问题难以缓解。发明人进一步研究发现,这是由于入料口和出料口设置在活塞的同一侧,入料口的进料方向与弹性储能件的推进方向相同导致的。
鉴于此,本申请还提供了下述方案:输料过渡机构包括本体、活塞和弹性储能件,本体设有活塞腔,活塞设置于活塞腔内,本体设有连通活塞腔的入料口和出料口,入料口和出料口位于活塞的一侧,弹性储能件设置于活塞腔且位于活塞的另一侧,弹性储能件被配置为在活塞被从入料口进入的浆料推动时变形并储存弹性势能,并在恢复变形时推动活塞以将浆料从出料口挤出,其中,活塞腔包括第一端壁和侧壁,第一端壁位于活塞的一侧,侧壁围设于第一端壁,入料口设置在活塞腔的侧壁。本申请提供的输料过渡机构,通过在活塞的一侧设置入料口和出料口、另一侧设置弹性储能件,并使入料口设置在活塞腔的侧壁,使得活塞推进方向和进料方向不同,避免活塞推出浆料时浆料在出料口受阻而导致骨料堆积,从而避免出现浆料离析、连续堆积骨料的连锁反应,缓解输料过渡机构内部堵塞和浆料离析的问题,保证稳定、持续供料。
本申请提供的输料过渡机构,不仅适用于建筑用的喷涂设备、喷涂抹平一体的设备,还适用于其他类型的浆料输送设备,实现浆料大流量地、连续地、稳定地输出。另外,本申请提供的输料过渡机构不仅适用于无骨料、细骨料的浆料,还能够适用于具有粗骨料的浆料,例如腻子、漆料薄抹灰砂浆、厚抹灰砂浆等。
以下以喷涂设备为例进行说明。在本申请的一些实施例中,如图1所示,喷涂设备包括储料装置1、喷涂装置(图1中未示出)、和泵送装置2。储料装置1用于储存浆料,喷涂装置用于将浆料喷涂于工作面(如地面或墙面),泵送装置2连接储料装置1和喷涂装置,以将储料装置1储存的浆料输出至喷涂装置。
其中,喷涂装置包括喷枪。
泵送装置2包括柱塞泵和输料过渡机构21,柱塞泵连接储料装置1,输料过渡机构21连接在柱塞泵和喷枪之间。结合图1和图3所示,柱塞泵的输出端通过输料管路3连接输料过渡机构21的入料口I,输料过渡机构21的出料口II通过出料管路4连接喷枪。
柱塞泵的特点为出料量较大(相比于螺杆泵),但其为脉冲式地间歇性出料,导致出料量不均匀。在泵送装置2和喷涂装置的配合下,柱塞泵将储料装置1中的浆料脉冲式地间歇性抽出并输送至输料过渡机构21,输料过渡机构21暂存柱塞泵送来的浆料,并连续地、稳定地输出至喷枪,实现连续向工作面快速喷涂浆料。从而,本申请提供的喷涂设备,在泵送装置2和喷涂装置的配合下,喷涂装置连续向工作面以较大流量喷涂浆料,有效提高工作效率。
在本申请的另一些实施例中,如图2所示,喷涂设备包括储料装置1、喷涂装置3000和泵送装置2。
储料装置1用于储存浆料,喷涂装置3000用于将浆料喷涂于工作面(如地面或墙面),泵送装置2连接储料装置1和喷涂装置3000,以将储料装置1储存的浆料输出至喷涂装置3000。可选地,喷涂装置3000为喷枪。
泵送装置2包括动力泵101和输料过渡机构21,动力泵101连接储料装置1,输料过渡机构21连接在动力泵101的出口,输料过渡机构21通过出料管路4连接喷枪。
可选地,动力泵101为柱塞泵,柱塞泵具有出料量较大的特点,但其出料方式为脉冲式出料,出料不连续。可选地,动力泵101为螺杆泵,螺杆泵相对柱塞泵而言出料相对稳定,但在储料装置1中的储量较少时,也存在出料不连续、不均匀的问题。通过设置输料过渡机构21,缓存浆料,并通过弹性储能件200、活塞211配合,实现将浆料连续地、均匀地输出至喷涂装置3000,同时本实施例提供的输料过渡机构21还具有不容易导致堵塞和不容易导致浆料离析的作用,能够保证浆料稳定、高效输送,使得喷涂装置3000能够连续稳定工作,喷涂设备整体工作效率较高。在一个实施例中,在浆料喷涂于工作面后,还需要将浆料抹平,以使浆料在工作面上凝固后形成平整的表面。目前,已有抹平设备解决抹平问题,通过喷涂设备和抹平设备双机联合,实现机械化作业。然而,由于喷涂设备和抹平设备各自的工作特性,双机联合施工存在调控配合的问题,两个设备作业时相互影响,有时采用两个设备先后工作的方式单独完成作业,有时采用人工协助的方式使得两个设备配合作业,或者将抹平设备的速度减慢,使抹平设备的作业速度与喷涂设备的作业速度一致,以便于配合作业,现有方式虽然能够完成作业,但工作效率较低。
鉴于此,本申请提供的喷涂设备还可以设置抹平装置(图中未示出),抹平装置用于将工作面上的浆料抹平,换句话说,本申请还可以提供一种喷抹一体机;或者喷涂设备先将浆料喷涂至墙面,独立于喷涂设备的抹灰设备再进行抹灰动作。喷抹一体机相比双机联合(抹灰设备和喷涂设备)作业而言,其抹平装置和喷头装置都能够高速地、连续地作业,抹平装置和喷头装置同步作业即可,调控配合方便,工作效率高,且相比双机联合作业需要较为宽敞的作业空间而言,本申请提供的喷抹一体机仅有一个底盘,节省了空间,占用空间小,便于在狭小的空间内周转和作业。
在另一实施例中,本申请的喷涂设备可以用于喷涂腻子、漆料等浆料,本申请的喷涂设备均可以用于要求出浆稳定的喷涂环境中,在此不再一一赘述。
在本申请的一些实施例中,如图3、图4和图5所示,本申请提供的输料过渡机构21包括装置本体100和弹性储能件200。装置本体100设有容纳空间,弹性储能件200设置于容纳空间内。
其中,容纳空间设有入料口I和出料口II,入料口I通过管路连接柱塞泵的输出端,出料口II通过管路连接喷枪。
弹性储能件200被配置为在浆料从入料口I进入时被浆料挤压变形以储存弹性势能,并且在恢复变形时释放弹性势能以将浆料从出料口II挤出。
换言之,在初始时,容纳空间被弹性储能件200占据,浆料从入料口I进入时,在泵浆压力作用下,浆料挤压弹性储能件200,弹性储能件200变形以让出空间,使得大量浆料能够被收容在容纳空间中。柱塞泵一次出浆过程结束后,泵浆压力消失,弹性储能件200逐渐恢复变形,释放弹性势能,以将浆料从出料口II逐渐挤出,从而实现将脉冲式间歇性供料转化为连续供料,进而能够实现大流量地连续喷涂, 提高工作效率。
输料过渡机构21的工作过程:柱塞泵将储料装置1中的浆料脉冲式地间歇性抽出,并同时向喷涂装置的方向输送,间歇性的周期时长预设为t,在一个周期中,柱塞泵的出料时长为t1,出料量为Q,不出料的时长为t2,其中,t1加上t2等于周期时长t,输料过渡机构21的容纳空间的容量为Q1,则在柱塞泵的出料时长的过程中,输料过渡机构21的平均出料速度为(Q-Q1)/t1,而在柱塞泵不出料时长的过程中,没有泵浆压力,不提供出料动力,通过弹性储能件200将容纳空间中剩余的浆料挤压至出料口II,在此期间的平均出料速度为Q1/t2,本申请的弹性储能件以及容纳空间被配置成使得(Q-Q1)/t1=Q1/t2。
以下以其中一个实施例作为说明:设t1=t2=t/2,Q1=Q/2,在前t/2的周期时间内柱塞泵的出料量为Q,后t/2的周期时间内柱塞泵不出料,则在一个周期内柱塞泵的出料总量为Q。柱塞泵连接输料过渡机构21之后,在前t/2的周期时间内,容纳空间内存储Q/2的浆料,另外Q/2的浆料通过平均速度为(Q/2)/(t/2)的速度出料,也就是说,在前t/2的周期时间内,柱塞泵将总量为Q的浆料送入输料过渡机构21的容纳空间,而输料过渡机构21同时以(Q/2)/(t/2)的速度出料,因此前t/2的周期时间之后,输料过渡机构21的出料量为Q/2,输料过渡机构21的容纳空间中剩余的浆料量为Q/2。在后t/2的周期时间内,柱塞泵不出料,没有泵浆压力,不提供出料动力,则通过弹性储能件200将容纳空间中剩余的浆料挤压至出料口II,在此期间,输料过渡机构21以(Q/2)/(t/2)的平均速度出料,从而输料过渡机构21在前半个周期和后半个周期的出料速度大体一致,实现在整个周期中保持出料稳定。
当然,柱塞泵的规格尺寸不相同,会导致出料时间t1和不出料时间t2也会不一样,本申请的输料过渡机构21弹性储能件以及容纳空间可以根据不同的柱塞泵做适配,以使得在出料的时间的出料速度和不出料的时间的出料速度大致相等。
弹性储能件200和装置本体100的结构有多种。
如图3、图4和图5所示,装置本体100被配置成包括筒状部110、第一端板120和第二端板130,第一端板120连接在筒状部110的一端,第二端板130连接在筒状部110的另一端,筒状部110、第一端板120和第二端板130共同围成容纳空间。
弹性储能件200包括分隔部210和弹性部220。分隔部210用于分隔容纳空间,弹性部220连接分隔部210和装置本体100,以用于储存和释放弹性势能。
分隔部210的形状被配置为与筒状部110适配,并能够在筒状部110中移动。分隔部210将容纳空间分隔为第一腔110a和第二腔110b,第一腔110a位于分隔部210的第一侧,第二腔110b位于分隔部210的第二侧,第一侧与第二侧相对,第一腔110a和第二腔110b互不连通。也即,在分隔部210作用下,第一腔110a和第二腔110b相互隔离,当分隔部210移动时,第一腔110a和第二腔110b此消彼长。
入料口I和出料口II均被配置为与第一腔110a连通,浆料进入第一腔110a时,将推动分隔部210由第一侧向第二侧移动,第一腔110a的空间增大,第二腔110b的空间减小。
可选地,弹性部220可以位于分隔部210的第一侧,即位于第一腔110a中,并连接分隔部210和第一腔110a的内壁。当分隔部210被浆料推向第二侧时,弹性部220受拉变形以储存弹性势能。
本实施例中,弹性部220位于分隔部210的第二侧,即位于第二腔110b中,弹性部220的一端抵持于装置本体100,弹性部220的另一端抵持于分隔部210,当分隔部210被浆料推向第二侧时,弹性部220受压变形以储存弹性势能。
通过推动分隔部210,以拉伸或压缩弹性部220实现储存弹性势能,弹性部220的形变方向和分隔部210的移动方向一致,分隔部210和弹性部220的运动路径明确,工作稳定,有利于浆料连续稳定输出。
并且,通过设置弹性部220的可形变行程,例如更换不同规格的弹性部220,能够调节最大储存量,也即调节第一腔110a的最大容量。根据泵送装置2的单次脉冲输出量,配置不同形变行程的弹性部220,调整最大储存量,以保证输料过渡机构21中浆料在完全输出之前获得补充,保证连续出料。
另外,当弹性部220位于第二腔110b时,弹性部220不接触浆料,弹性部220不容易被腐蚀、被污染,提高弹性部220的耐久性。
弹性部220可选用金属弹簧、弹性橡胶、气垫等,本申请实施例中采用氮气弹簧。氮气弹簧具有体积小、弹力大、行程长、工作平稳、使用寿命长的特点,通过将弹性部220设置为氮气弹簧,使得输料过渡机构21整体结构更紧凑,氮气弹簧释放弹性势能的过程更平稳,有利于连续地、稳定地输出浆料。
为保证分隔部210运动流畅性,保证出料连续稳定,分隔部210被配置为包括活塞211和密封组件。
可选地,筒状结构的内腔为圆柱形,也即容纳空间为圆柱形,活塞211为圆柱形。
在泵浆压力和弹性力作用下,活塞211沿容纳空间的轴向来回移动,实现脉冲式浆料收容和连续式浆料输出。
密封组件阻挡浆料经活塞211和容纳空间的内壁之间的缝隙进入第二腔110b,其一避免浆料向第二腔110b泄漏,保证浆料稳定输出至出料口II,其二避免弹性部220接触浆料受损,延长弹性部220的耐久性,保证弹性部220能够提供足够的弹性力驱动活塞211,以输出浆料。
可选地,结合图5和图6所示,密封组件包括弹性板212和压板213,弹性板212位于压板213和活塞211之间,压板213与活塞211连接以压紧弹性板212,弹性板212的外周面与容纳空间的内壁紧密接触。
如图6所示,弹性板212和压板213位于分隔件的第一侧,弹性板212可选用弹性橡胶板,压板213可选用硬质塑胶板、不锈钢板等,弹性板212通过压板213固定在活塞211的端面上,容纳空间的内壁挤压弹性板212的外周面,形成环形密封区域,从而实现密封隔离的作用,以限制浆料通过活塞211和容纳空间的内壁之间的缝隙。
在分隔部210在弹性部220推动下,由第二侧向第一侧移动的过程中,弹性板212还能够将容纳空间的内壁上的浆料刮除,以免浆料挂壁,使浆料能够尽可能输出。
通过弹性板212刮除容纳空间的内壁上的浆料,还防止残留的浆料存在于分隔部210的第二侧,以免弹性部220和活塞211被腐蚀、被污染而受损。另外,还使得活塞211和容纳空间的内壁之间不存在浆料,以免活塞211运动时被浆料中的颗粒物磨损,还减小活塞211运动的摩擦力,以免运动受干涉,保证活塞211能够流畅地在容纳空间内运动,进而保证稳定地、连续地输出浆料。可选地,结合图5和图6所示,密封组件还包括密封圈214,密封圈214套设于活塞211的外周面上。通过在活塞211的外周面上设置密封圈214,活塞211和容纳空间的内壁配合压缩密封圈214,以形成环形的密封区域,从而提高分隔部210的密封隔离效果,以免浆料泄漏至分隔部210的第二侧,保证浆料稳定地、连续地从出料口II输出。在一些实施例中,结合图5和图6所示,分隔部210还包括导向环215,导向环215设置于活塞211的外周面上,导向环215沿活塞211本体的径向凸出于活塞211的外周面。
导向环215采用硬质材料制成,如不锈钢、铜、合金等金属材料制成,或特氟龙等硬质高分子树脂材料制成。
导向环215与活塞211可以是分体式结构,即导向环215与活塞211分别成型后,将导向环215套设在活塞211的外周面。导向环215与活塞211可以是一体成型,如在活塞211及其外周面上的导向环215一次模铸成型,又如在活塞211的外部通过切削等方式形成凸出于其外周面的导向环215。
通过将导向环215设置在活塞211的外周面,活塞211通过导向环215接触容纳空间的内壁,二者的接触面积减小,活塞211移动时的摩擦面积减小,受到的摩擦力减小,保证活塞211能够流畅地在容纳空间内运动,进而保证稳定地、连续地输出浆料。
本申请实施例中,入料口I和出料口II设置在装置本体100上,如图5所示,入料口I和出料口II均设置在第一端板120上。
在其他实施例中,入料口I和出料口II也可以设置在分隔部210上,在第二端板上设置通孔,分别将外部管路穿过通孔连接至入料口I和出料口II;或者取消第二端板130以开放筒状部110的一端,并将外部管路连接至入料口I和出料口II。
入料口I和出料口II也可以为一者设置于装置本体100,另一者设置于分隔部210。
本实施例中,通过将入料口I和出料口II均设置在装置本体100上,用于连接泵送装置2和喷枪的管路连接在装置本体100上,而非连接在弹性储能件200上,简化了弹性储能件200的结构和功能,使得弹性储能件200结构简单、工作稳定,弹性储能件200是活动部件,便于损坏,如此设置还便于更换 弹性储能件200。
在本申请的另一些实施例中,如图7和图8所示,输料过渡机构21包括装置本体100、活塞211和弹性储能件200。在实施例中,装置本体100可以被称为本体。
装置本体100设有容纳空间,装置本体100还设有连通容纳空间的入料口I和出料口II。在实施例中,容纳空间可以为活塞腔11。
活塞211和弹性储能件200均设置于容纳空间内,且入料口I和出料口II位于活塞211的一侧,弹性储能件200位于活塞211的另一侧。
可选地,如图8所示,活塞211的外周面上套设有密封圈214,活塞211的外周面和容纳空间的侧壁12配合压缩密封圈214,以封堵活塞211的外周面和容纳空间的侧壁12之间的缝隙,以免浆料泄漏至活塞211的另一侧。
可选地,活塞211的一侧还设有弹性板212和硬板23,弹性板212位于硬板23和活塞211之间,硬板23与活塞211连接以压紧弹性板212,弹性板212的外周面与侧壁12紧密接触,以限制浆料通过活塞211的外周面和侧壁12之间的缝隙。弹性板212可选用弹性橡胶板,硬板23可选用硬质塑胶板、不锈钢板等。
弹性储能件200被配置为在活塞211被从入料口I进入的浆料推动时变形并储存弹性势能,并在恢复变形时推动活塞211以将浆料从出料口II挤出。弹性储能件200可以是弹性膜片、金属弹簧、弹性气囊、氮气弹簧中的一种。示例性地,弹性储能件200为氮气弹簧。
其中,容纳空间包括第一端壁和侧壁12,第一端壁位于活塞211的一侧,侧壁12围设于第一端壁,入料口I设置在容纳空间的侧壁12。
在动力泵101的泵浆压力下,浆料从入料口I沿容纳空间的径向进入,并挤压活塞211的面向第一端壁的一侧,使得活塞211逐渐远离第一端壁,活塞211让出空间以储存浆料,并压缩弹性储能件200以储存弹性势能。
在泵浆压力减小或消失时,弹性储能件200逐渐恢复变形,释放弹性势能,以推动活塞211,将浆料沿容纳空间的轴向推动,实现挤出浆料,从而保证连续地、稳定地、大流量地输出浆料。
由于活塞211推进方向和进料方向不同,还避免活塞211推出浆料时浆料在出料口II受阻而导致骨料堆积,从而避免出现浆料离析、连续堆积骨料的连锁反应,缓解输料过渡机构21内部堵塞和浆料离析的问题,保证稳定、持续供料。
如图8所示,为保证输料过渡机构21的稳定性,入料口I相对活塞211更靠近第一端壁,以使得入料口I在活塞211的行程以外,避免活塞211遮挡入料口I,保证顺利进料。
在一些实施例中,容纳空间的与第一端壁沿轴向相对的一端可以不封闭,以减小输料过渡机构21的整体质量,弹性储能件200可以连接于侧壁12。
在另一些实施例中,容纳空间的与第一端壁沿轴向相对的一端设有第二端壁14。如图7所示,第二端壁14位于活塞211的另一侧,弹性储能件200抵接于第二端壁14。
可选地,弹性储能件200被配置为支撑在第二端壁14和活塞211之间。换言之,弹性储能件200以预压缩的状态设置在第二端壁14和活塞211之间,保证活塞211移动过程中均对弹性储能件200产生压力,进一步保证出料稳定。
如图7和图8所示,出料口II设置在第一端壁,使得出料口II的出料方向和活塞211推进方向相同,从而避免活塞211的推力损失,保证活塞211的推力尽可能转化为出料动力,从而提高出料动力,缓解出料口II堵塞和离析的问题。
可选地,出料口II的口径不小于容纳空间的内径。换言之,出料口II完全覆盖容纳空间的一端,也可以理解为容纳空间不具有第一端壁,以使得浆料能够直接进入出料口II,不会导致浆料在进入出料口II前被挤压而出现离析现象,从而避免砂浆在出料口II处堆积,进一步解决了堵塞和离析的问题。
另一方面,相比相关技术,在出料口II的口径不变的情况下,容纳空间的直径能够设置得较小,从而能够减小输料过渡机构21的整体体积和质量。
可选地,如图7和图8所示,输料过渡机构21还包括出料管6,出料管6包括第一端61和第二端 62,第一端61连接于出料口II,出料管6的内径由第一端61向第二端62逐渐减小。
也就是说,出料管6为锥形,其中,锥形的大端朝向容纳空间,锥形的小端连接出料管路4。出料管6的锥形内壁具有引导作用,使得浆料流动更流畅,进而使得浆料在活塞腔11内部沉降少,不易失水硬化在里面。
本申请通过在侧壁12设置入料口I、在第一端壁设置口径大于容纳空间内径的出料口II,并设置锥形的出料管6,除了能够起到缓解堵塞、离析,实现稳定连续出料,以及减小输料过渡机构21的整体体积和质量,还利于浆料流动,能够减小浆料输出所需的推力,经测试发现,同样出浆量下,所需推力减小约1/3。
因此,进一步地,相比相关技术,弹性储能件200的规格可以减小1/3,例如,氮气弹簧的压力能够降低1/3,氮气弹簧的重量大大减小,从而进一步输料过渡机构21的整体体积和质量减小。
在本发明的一些实施例中,在柱塞泵停止出浆时,在喷枪作用下,浆料一般将从出料口II流出,不容易向入料口I回流,但有时喷枪停止工作时,或喷枪故障时,有可能向入料口I回流。为解决这一问题,可选地,在入料口I设置单向阀300,防止浆料回流,保证稳定地、连续地输出浆料。
在本申请的一些实施例中,参见图4、图5、图9、图10、图11、图12,单向阀300包括安装座310、挡板320、转销330和弹性复位组件340。
安装座310连接于装置本体100,安装座310上设有一开口,该开口与入料口I对应。
挡板320通过转销330连接于安装座310,当挡板320覆盖安装座310上的开口时,实现封闭入料口I。
弹性复位组件340用于驱使挡板320封闭入料口I。在一些实施例中,弹性复位组件340可以被配置为扭簧,扭簧套设于转销330,扭簧的两端分别连接安装座310和挡板320;或者,弹性复位组件340可以被配置为拉簧342,拉簧342的两端分别连接安装座310和挡板320。
在本实施例中,请再参照图9、图10和图11所示,弹性复位组件340包括拉杆341和拉簧342。
转销330的端部延伸至安装座310的外表面,如图10所示。换言之,安装座310的开口处形成内表面,该内表面围成安装座310上的开口,挡板320的两侧分别连接有转销330,转销330穿过内表面并伸出至安装座310的外表面,如图11所示。
拉杆341与转销330的端部固定连接,具体地,转销330的端部固定连接至形成在拉杆341上的开孔,从而拉杆341、转销330和挡板320同步转动。
拉簧342的一端连接安装座310,拉簧342的另一端连接拉杆341。如图12所示,当浆料推动挡板320沿图12中的箭头所示的进料方向进入时,带动转销330转动,使拉杆341摆动,拉伸拉簧342,当柱塞泵出浆结束后,拉簧342恢复变形,将拉杆341拉回原位,通过转销330带动挡板320重新覆盖安装座310上的开口,以封闭入料口I。
通过将转销330延伸至安装座310的外表面,并将弹性复位组件340设置在安装座310的外部,一方面,防止弹性复位组件340接触浆料受损,提高单向阀300的耐久性;另一方面,还便于从外部观察转销330、拉杆341和拉簧342的位置,获知挡板320是否遮挡入料口I,以及观测单向阀300是否还具有单向放行的作用,以便于维修更换,进而保证输料过渡机构21能够稳定地、连续地输出浆料。
再次参见图11和图12,为防止挡板320沿与图12所示的进料方向相反的方向运动,还设置有止挡杆350,止挡杆350穿设于形成在安装座310中的止挡杆安装孔351。当出浆结束之后,一方面,挡板320由于拉簧342恢复变形而重新覆盖安装座310;另一方面,挡板320由于止挡杆350而无法沿与图12所示的进料方向相反的方向运动。由此,挡板320仅能够沿与进料方向相同的方向运动,从而较好地防止了浆料回流。
另外,考虑到初始状态下,即浆料首次进入输料过渡机构21前,挡板320抵触在分隔部210上,可能导致挡板320无法转动打开,如图4、图5、图9、图10、图11和图12所示,装置本体100设置一连接管140,用于连接安装座310,以增大挡板320和分隔部210之间的距离,以免浆料首次进入时挡板320被分隔部210阻挡而不能打开。
如图4和图5所示,连接管140从入料口I的边缘沿垂直于入料口I所在平面的方向向外伸出。也 即,入料口I开设于第一端板120,连接管140连接于第一端板120,连接管140的管口覆盖入料口I。
通过设置连接管140,保证浆料能够推开挡板320进入连接管140,进而浆料能够直接作用于分隔部210,并推动分隔部210压缩弹性部220。
另外,连接管还增加了安装座310与第一端板120之间的距离,为拉簧342、拉杆341的安装和活动提供空间。
在一些实施例中,第一端板120的面向分隔部210的一面形成限位凸起121,通过该限位凸起121来防止挡板320受分隔部210阻挡而无法转动开启。另外,该限位凸起121还限制分隔部210和第一端板120全面贴紧,以免残留浆料将分隔部210和第一端板120粘连在一起。
在本申请的一些实施例中,输料过渡机构21还包括进料管8,图1中示出的输料管路3套设于进料管8。参照图10和图11,进料管8连接在安装座310的与设置有连接管140相反的表面上。如图11和图12所示,在进料管8、安装座310和连接管140上分别设置有连接孔810、311和141,进料管8、安装座310和连接管140通过设置在连接孔810、311和141中的连接件连接在一起。
在本申请的图7和图8所示的另一些实施例中,输料过渡机构21也包括单向阀300,参照图7和图8,单向阀300设置于入料口I。在活塞211推进并挤出浆料时,单向阀300封闭入料口I,进一步防止浆料在入料口I处堆积,缓解浆料堵塞和离析的问题。
如图13、图14和图15所示,单向阀300包括安装座310、挡板320、转销330、拉杆341和拉簧342。
安装座310设置于入料口I并连接装置本体100。安装座310包括朝向容纳空间内部的第一表面711和背离容纳空间内部的第二表面712,安装座310设有连通入料口I的通孔713,通孔713的一端贯穿至第一表面711,通孔713的另一端贯穿至第二表面712。
挡板320通过转销330连接于安装座310,当挡板320覆盖通孔713时,实现封闭入料口I。在一些实施例中,挡板320也可以贴合于侧壁12以直接覆盖入料口I。通过将挡板320设置为覆盖通孔713,在安装单向阀300之前即可调试并确认安装单向阀300的可靠性。
转销330的端部延伸至安装座310的外表面,安装座310的外表面设置连接所述第一表面711和所述第二表面712的面。
拉杆341与转销330的端部固定连接,拉簧342的一端相对安装座310固定,拉簧342的另一端连接拉杆341,以驱使挡板320封闭入料口I。
通过上述设置,安装座310、挡板320、转销330、拉杆341和拉簧342构成的单向阀300为整体模块,且拉簧342、拉杆341等结构在安装座310的外部,转销330、拉杆341和拉簧342没有在通孔713内,不会阻挡浆料,不容易造成堵塞和离析问题。另一方面,转销330、拉杆341和拉簧342还不容易受浆料腐蚀,提高了单向阀300的稳定性。再一方面,还便于从外部观察拉杆341,以判断挡板320是否遮挡入料口I,从而便于检修单向阀300。
可选地,单向阀300还包括连接座76,连接座76连接于安装座310,连接座76设有多个连接位761,多个连接位761与拉杆341的距离不同,拉簧342的一端择一地连接于多个连接位761。通过设置具有多个连接位761的连接座76,实现调节拉簧342的拉力,以保证单向阀300可靠运行。
如图1,3、图14和图15所示,连接座76为U型,U型的底部通过固定件连接于安装座310,U型的臂部沿远离安装座310的方向延伸并设有沿其延伸方向排布的多个连接位761。
可选地,连接位761为卡孔,拉簧342的一端连接于卡孔。
可选地,单向阀300还包括第一连接杆762和第二连接杆741。第一连接杆762的一端插接于卡孔,第一连接杆762的另一端设有第一挂孔(图中未示出),所述拉簧342的一端挂设于第一挂孔。第二连接杆741的一端连接于拉杆341,第二连接杆741的另一端设有第二挂孔(图中未示出),所述拉簧342的另一端挂设于第二挂孔。
可选地,输料过渡机构21还包括进料管8,进料管8连接于第二表面712并与通孔713连通。因此,安装座310同时起到连接进料管8的作用,便于装配。
在本申请的一些实施例中,输料过渡机构21还包括行程标识杆400,行程标识杆400位于分隔部 210的第二侧,且行程标识杆400的一端连接于分隔部210并伸出装置本体100。
如图5所示,行程标识杆400平行于筒状部110,分隔部210由第一侧向第二侧移动时,行程标识杆400伸出装置本体100的长度增加,分隔部210由第二侧向第一侧移动时,行程标识杆400伸出装置本体100的长度减少。
通过设置行程标识杆400,能够获知分隔部210在容纳空间中的所处的位置,得到分隔部210的移动情况,进而获知浆料的输出情况,方便从外部观测输料过渡机构21是否正常工作。
可选地,在本申请的另一些实施例中,如图8所示,输料过渡机构21还包括滑动杆40,滑动杆40包括第一段41和第二段42。其中,第一段41连接于活塞211,第二段42穿过第二端壁14并伸出装置本体100。活塞211移动时,滑动杆伸出装置本体100的长度发生变化,从而滑动杆能够标识活塞211在容纳空间11内的位置,便于确认活塞211是否正常工作,方便检修。
可选地,输料过渡机构21还包括限位件5,限位件5连接于第二段42并位于装置本体100的外侧。在活塞211移动过程中,限位件5通过滑动杆跟随活塞211移动,当移动至限位件5抵接于装置本体100的外表面时,能够限制活塞211朝向第一端壁移动。通过滑动杆和限位件5配合,能够限定活塞211的行程,保证入料口I在活塞211的行程以外,实现避免活塞211遮挡入料口I。
可选地,第二段42设有外螺纹,限位件5为螺母,限位件5与第二段42螺纹配合。转动限位件5,能够使限位件5沿第二段42移动,从而起到调节活塞211的最大行程的作用。
在常规工作状态下,调小活塞211的行程,防止活塞211经过入料口I。
在停止工作之前,将活塞211的行程调至最大,使得活塞211能够移动至第一端壁,以保证将容纳空间中的浆料全部推出。
在本申请的再一些实施例中,输料过渡机构21还可以配置为其他结构。
例如,将前述的弹性储能件200设置为边缘连接于装置本体100的弹性膜件,通过弹性膜件的储存弹性势能和释放弹性势能。
又如,如图16所示,装置本体100内部形成容纳空间,弹性储能件200包括设置在容纳空间中的弹性管道230,入料口I和出料口II分别设置在装置本体100的两端,弹性管道230的一端连接入料口I,弹性管道230的另一端连接出料口II。
弹性管道230在自然状态下处于收缩状态,弹性管道230与容纳空间的内壁间隔较大,中部管径小于入料口I的口径。
柱塞泵出浆时,浆料从入料口I涌入弹性管道230,并挤压弹性管道230的管壁,使得弹性管道230的管壁朝向容纳空间的内壁扩张,弹性管道230与容纳空间的内壁间隔减小。柱塞泵停止出浆时,泵浆压力消失,弹性管道230恢复变形,管径逐渐缩小,从而将浆料从出料口II挤出。
可选地,如图16所示,弹性储能件200还包括弹性填充材料240,弹性填充材料240填充于弹性储能件200和容纳空间的内壁之间,当浆料进入弹性管道230时,弹性管道230的管壁扩张,弹性填充材料240受挤压,弹性管道230和弹性填充材料240共同储存弹性势能,并在泵浆压力消失后,一起释放弹性势能,以将浆料从出料口II挤出。
弹性填充材料240可以选用松散的、高弹性的橡胶球。以上所述仅为本申请的优选实施例而已,并不用于限制本申请,对于本领域的技术人员来说,本申请可以有各种更改和变化。凡在本申请的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本申请的保护范围之内。
