技术领域technical field
本实用新型属于强制式振动搅拌机设备的技术领域,特别涉及一种空心搅拌轴等幅振动的强制式振动搅拌机。The utility model belongs to the technical field of forced vibration mixer equipment, in particular to a forced vibration mixer with equal-amplitude vibration of a hollow stirring shaft.
背景技术Background technique
混凝土搅拌机是将水泥、砂、石和水等材料按照一定比例搅拌成均匀且符合实际施工要求的混凝土的专用设备。现有的普通搅拌机多是通过搅拌轴带动搅拌臂上的搅拌叶片对各种原料进行搅拌,以达到混合均匀。研究发现普通搅拌机只能使物料达到宏观上的均匀,宏观上均匀的混凝土通过显微镜观察发现仍有一部分水泥颗粒粘聚成微小的水泥球,即物料在微观上未达到均匀。这便使得水泥的水化作用不能充分发挥,混凝土结构物的强度和耐久性仍有很大提升潜力。Concrete mixer is a special equipment for mixing materials such as cement, sand, stone and water according to a certain proportion into concrete that is uniform and meets the actual construction requirements. Most of the existing ordinary mixers drive the mixing blades on the stirring arm through the stirring shaft to stir various raw materials to achieve uniform mixing. The study found that the ordinary mixer can only make the material uniform on the macroscopic level, and the macroscopically uniform concrete is observed through a microscope to find that some cement particles still cohere into tiny cement balls, that is, the material is not uniform on the microscopic level. As a result, the hydration of cement cannot be fully exerted, and the strength and durability of concrete structures still have great potential for improvement.
现有的振动搅拌机很好的解决了这一问题。新出现的振动搅拌机通过宏观搅拌和微观振动结合,破坏水泥结团现象,使得水泥的水化作用增强,不仅提高了混凝土的质量,而且减少了水泥的用量。Existing vibrating mixer has solved this problem well. The new vibrating mixer breaks the cement agglomeration phenomenon through the combination of macroscopic stirring and microscopic vibration, so that the hydration of cement is enhanced, which not only improves the quality of concrete, but also reduces the amount of cement used.
现有的振动搅拌机如专利201510231725.6中,由于通过激振器相连接的振动轴和搅拌轴之间存在一定的偏心距,这使得搅拌轴在工作过程中既绕着自身轴线自转,同时又绕着振动轴的轴线公转,并且其公转半径呈现出一种从左端到右端递减的锥形状态。这就造成一些局限,一方面,搅拌轴长度方向振幅不等大,振动搅拌效应未充分发挥,搅拌质量和效率仍有提高空间;另一方面,搅拌轴与搅拌筒壳体密封孔之间的间隙交变,密封结构复杂且不可靠,容易造成漏浆。In existing vibrating mixers such as patent 201510231725.6, due to the existence of a certain eccentricity between the vibration shaft and the stirring shaft connected by the vibrator, this makes the stirring shaft not only rotate around its own axis during the working process, but also around the The axis of the vibrating shaft revolves, and its revolution radius presents a tapered state that decreases from the left end to the right end. This has caused some limitations. On the one hand, the amplitude of the stirring shaft length is not equal, the vibration stirring effect is not fully exerted, and there is still room for improvement in the stirring quality and efficiency; on the other hand, the sealing hole between the stirring shaft and the mixing drum shell The gaps alternate, the sealing structure is complex and unreliable, and it is easy to cause slurry leakage.

实施例1:Example 1:
如图1所示,振动搅拌机的搅拌驱动装置由两个相同的搅拌驱动电机7和减速机6组成。搅拌驱动电机7的电机轴通过带传动与减速机6的输入轴相连接,两个减速机6的输入轴通过传动轴实现两减速机的同步转动。减速机6的输出轴与搅拌轴4相连接,从而实现正常工作中搅拌轴的转动。As shown in Figure 1, the stirring drive device of the vibrating mixer consists of two identical stirring drive motors 7 and a reducer 6. The motor shaft of the stirring drive motor 7 is connected with the input shaft of the speed reducer 6 through a belt drive, and the input shafts of the two speed reducers 6 realize the synchronous rotation of the two speed reducers through the transmission shaft. The output shaft of the reducer 6 is connected with the stirring shaft 4, so as to realize the rotation of the stirring shaft during normal operation.
振动搅拌机的振动装置由一个或两个相同的振动驱动电机1和振动轴9组成。振动驱动电机1的电机轴通过带传动与振动轴9的左端相连接,振动轴9的右端横穿于空心搅拌轴内,通过搅拌轴两端设置的第二支撑轴承13带动搅拌轴4的转动,实现正常工作中的振动功用。The vibrating device of the vibrating mixer consists of one or two identical vibrating drive motors 1 and vibrating shafts 9 . The motor shaft of the vibrating drive motor 1 is connected to the left end of the vibrating shaft 9 through a belt drive, the right end of the vibrating shaft 9 traverses the hollow stirring shaft, and the second support bearing 13 provided at both ends of the stirring shaft drives the rotation of the stirring shaft 4 , to achieve the vibration function in normal work.
在振动搅拌机的结构布置中,振动轴9上安装有第一支撑轴承10,其左端通过带传动连接在振动驱动电机1的电机轴上,其右端通过搅拌轴两端设置的第二支撑轴承13横穿于空心搅拌轴内。在搅拌装置中,由于两个减速机6的输入轴通过传动轴相连接,所以两个搅拌轴5始终处于同步转动。而在振动装置中,两根振动轴9分别由一个或两个独立的振动驱动电机1驱动,所以通过激振器相连接的振动轴9和搅拌轴4可以实现在不同转速下正常工作。In the structural arrangement of the vibrating mixer, a first supporting bearing 10 is installed on the vibrating shaft 9, its left end is connected to the motor shaft of the vibrating drive motor 1 through a belt drive, and its right end passes through the second supporting bearing 13 provided at both ends of the agitating shaft across the hollow stirring shaft. In the stirring device, since the input shafts of the two reducers 6 are connected through the transmission shaft, the two stirring shafts 5 are always in synchronous rotation. In the vibrating device, the two vibrating shafts 9 are respectively driven by one or two independent vibrating drive motors 1, so the vibrating shaft 9 and the stirring shaft 4 connected by the vibrator can work normally at different speeds.
普通振动搅拌机中,由于振动轴和搅拌轴之间偏心的存在,则在振动搅拌机的工作过程中,搅拌轴既要绕着自身轴线自转,同时又要绕着振动轴的轴线公转,并且其公转半径呈现出一种从左端到右端逐渐递减的锥形状态。这不仅造成了搅拌轴与搅拌筒轴孔之间的密封困难,而且搅拌轴的不等幅振动降低了振动搅拌效应,加剧了支撑轴承的磨损,大大减小了振动搅拌机的使用寿命。为此采用了在两根搅拌轴4的左、右端均与振动轴有偏心且加装反向偏心套8,使得反向偏心套8的转动中心与搅拌筒壳体密封孔中心重合,偏心套和搅拌筒壳体间采用常用密封装置11,使得搅拌轴在整个工作过程中始终处于等幅振动状态,增强了振动搅拌效应。另外,还将不等幅振动的复杂密封转化为等幅振动的简单密封,而且减小了搅拌轴两端支撑轴承的磨损。In ordinary vibrating mixers, due to the eccentricity between the vibrating shaft and the agitating shaft, during the working process of the vibrating mixer, the agitating shaft should not only rotate around its own axis, but also revolve around the axis of the vibrating shaft, and its revolution The radius presents a tapered state that gradually decreases from the left end to the right end. This not only makes it difficult to seal between the stirring shaft and the shaft hole of the mixing drum, but also the unequal amplitude vibration of the stirring shaft reduces the vibration stirring effect, aggravates the wear of the support bearing, and greatly reduces the service life of the vibrating mixer. For this reason, the left and right ends of the two stirring shafts 4 are eccentric with the vibration shaft and the reverse eccentric sleeve 8 is installed, so that the rotation center of the reverse eccentric sleeve 8 coincides with the center of the sealing hole of the mixing drum shell, and the eccentric sleeve The common sealing device 11 is adopted between the mixing drum shell and the mixing shaft, so that the stirring shaft is always in a state of equal amplitude vibration during the whole working process, which enhances the vibration stirring effect. In addition, the complex seal with unequal amplitude vibration is converted into a simple seal with equal amplitude vibration, and the wear of the supporting bearings at both ends of the stirring shaft is reduced.
实施例2:Example 2:
如图2所示,振动搅拌机的搅拌驱动装置由一个搅拌驱动电机7和减速机6组成。搅拌驱动电机7的电机轴通过带传动与减速机6的输入轴相连接,两个减速机6的输入轴通过传动轴实现两减速机的同步转动。减速机6的输出轴与搅拌轴5相连接,从而实现正常工作中搅拌轴的转动。As shown in FIG. 2 , the stirring drive device of the vibrating mixer is composed of a stirring drive motor 7 and a reducer 6 . The motor shaft of the stirring drive motor 7 is connected with the input shaft of the speed reducer 6 through a belt drive, and the input shafts of the two speed reducers 6 realize the synchronous rotation of the two speed reducers through the transmission shaft. The output shaft of the reducer 6 is connected with the stirring shaft 5, so as to realize the rotation of the stirring shaft during normal operation.
振动搅拌机的振动装置由一个或两个相同的振动驱动电机1和振动轴9组成。振动驱动电机1的电机轴通过带传动与振动轴9的左端相连接,振动轴9的右端横穿于空心搅拌轴内,通过搅拌轴两端设置的第二支撑轴承13带动搅拌轴4的转动,实现正常工作中的振动功用。The vibrating device of the vibrating mixer consists of one or two identical vibrating drive motors 1 and vibrating shafts 9 . The motor shaft of the vibrating drive motor 1 is connected to the left end of the vibrating shaft 9 through a belt drive, the right end of the vibrating shaft 9 traverses the hollow stirring shaft, and the second support bearing 13 provided at both ends of the stirring shaft drives the rotation of the stirring shaft 4 , to achieve the vibration function in normal work.
在振动搅拌机的结构布置中,振动轴9通过第一支撑轴承10安装在机架上,其左端通过带传动连接在振动驱动电机1的电机轴上,其右端通过搅拌轴两端设置的激振器内部的轴承横穿于空心搅拌轴内。在搅拌装置中,由于两个减速机6的输入轴通过传动轴相连接,所以两个搅拌轴5始终处于同步转动。而在振动装置中,两根振动轴9分别由一个振动驱动电机1驱动,所以通过激振器相连接的振动轴9和搅拌轴4可以实现在不同转速下正常工作。In the structural arrangement of the vibrating mixer, the vibrating shaft 9 is installed on the frame through the first supporting bearing 10, its left end is connected to the motor shaft of the vibrating drive motor 1 through a belt drive, and its right end is vibrated by the vibration excitation provided at both ends of the agitating shaft. The bearing inside the device traverses the hollow stirring shaft. In the stirring device, since the input shafts of the two reducers 6 are connected through the transmission shaft, the two stirring shafts 5 are always in synchronous rotation. In the vibrating device, the two vibrating shafts 9 are respectively driven by a vibrating drive motor 1, so the vibrating shaft 9 and the stirring shaft 4 connected by the vibrator can work normally at different speeds.
