Description
技术领域technical field
本发明属于混凝土搅拌机技术领域，尤其涉及一种提料式立轴行星搅拌机。The invention belongs to the technical field of concrete mixers, in particular to a material-lifting vertical shaft planetary mixer.
背景技术Background technique
搅拌机是制备混凝土的必需设备。立轴行星式搅拌机是一种常见的混凝土搅拌机型，工作时主要通过行星搅拌工具的自转和公转运动，来实现对混凝土混合料的强制拌和。由于具有搅拌作用强烈、无搅拌死区、密封性好等诸多优点，立轴行星式搅拌机得到了迅速的推广与发展。现有立轴搅拌机在搅拌的过程中主要依靠圆周方向的运动来实现均匀搅拌，缺乏高度方向上的强制提料作用，从而造成搅拌筒体的直径与高度之比往往较大，而搅拌机的装料容量取决于搅拌筒体的尺寸，因此这种直径与高度比值较大的立轴搅拌机的容量越大，其搅拌筒体的直径尺寸就越显著，从而导致成品搅拌机难以运输，使得搅拌机的大型化受到限制。同时，搅拌筒体直径越大，搅拌刀在公转过程中的线速度就越大，致使混合料受到的离心力作用就越大，从而增加了混合料在搅拌过程中发生离析的风险。A mixer is a necessary equipment for preparing concrete. Vertical shaft planetary mixer is a common type of concrete mixer. It mainly realizes the forced mixing of concrete mixture through the rotation and revolution of the planetary mixing tool during work. Due to many advantages such as strong stirring effect, no stirring dead zone, and good sealing performance, the vertical shaft planetary mixer has been rapidly popularized and developed. The existing vertical shaft mixer mainly relies on the movement in the circumferential direction to achieve uniform mixing during the mixing process, and lacks the forced lifting effect in the height direction, so that the ratio of the diameter to the height of the mixing cylinder is often large, and the loading of the mixer The capacity depends on the size of the mixing cylinder, so the larger the capacity of the vertical shaft mixer with a larger ratio of diameter to height, the more significant the diameter of the mixing cylinder, which makes it difficult to transport the finished mixer, making the size of the mixer limited. limit. At the same time, the larger the diameter of the mixing cylinder, the greater the linear velocity of the mixing knife during the revolution process, resulting in greater centrifugal force on the mixture, thereby increasing the risk of segregation of the mixture during the mixing process.
发明内容Contents of the invention
为解决以上问题，本发明提供一种提料式立轴行星搅拌机，可在搅拌的同时进行周期性提料动作，有助于缩小搅拌筒体的径高比，进而降低了搅拌的线速度，可避免混合料在搅拌过程中发生离析现象。In order to solve the above problems, the present invention provides a material-lifting vertical shaft planetary mixer, which can perform periodic material-lifting actions while stirring, which helps to reduce the diameter-to-height ratio of the mixing cylinder, thereby reducing the linear speed of stirring, and can Avoid segregation of the mixture during the stirring process.

While stirring, the reciprocating material lifting movement is carried out periodically to form a vertical circulating material flow in the mixing drum, so that the mixture in the mixing drum can be well stirred from all directions, with high stirring efficiency and good mixing quality. At the same time, under the condition that the capacity of the mixer remains unchanged, the diameter-to-height ratio of the mixing drum can be reduced, which is conducive to the transportation and enlargement of the mixer. At the same time, it also reduces the linear speed at the end of the planetary mixer, which can avoid the mixing of the mixture. Segregation occurred during stirring.
