技术领域 technical field
本发明涉及一种以斜向进气流为动力的四涡旋动能制浆设备，尤其涉及一种通过圆形结构的圆形进气管形成以低能损进入支进气管的环流，通过4个弧形结构且由圆形进气管斜向接出的支进气管实现气流低能耗进入碎浆机筒，以及形成高效制浆的4个多区域、无死角、相互碰撞的小涡旋，属于造纸业制浆设备的技术研发领域。 The invention relates to a four-vortex kinetic energy pulping equipment powered by oblique air intake, in particular to a circular air intake pipe with a circular structure to form a circular flow entering the branch air pipe with low energy loss, through four arcs The structure and the branched air pipes connected obliquely from the circular air pipes realize the low energy consumption of the airflow into the pulper barrel, and form four multi-zone, no dead angle, small vortexes that collide with each other for efficient pulping, which belongs to the papermaking industry.

背景技术 Background technique
水力碎浆机作为造纸工业中最常用的制浆设备，其通过转子的运动，将水中的浆板、废旧书本、废旧纸箱等进行碎解，并制成均匀悬浮液。但是由于目前碎浆机工作方式以及结构的单一性，造成以下问题：一是效率低，现有碎浆机通过料液与转子、桶壁的机械碰撞实现碎浆，而碰撞的动力来源于转子对液料的搅动，在碎浆的过程中，有一部分的能量消耗在机械的无功损耗上，因此造成机械制浆的效率很低；二是能耗大、浪费资源，碎浆机转子在工作过程中，不仅要带动流体转动，而且还要克服流体的阻力，这在一定程度上要消耗大量的机械能。 As the most commonly used pulping equipment in the paper industry, the hydropulper breaks up pulp boards, waste books, waste cartons, etc. in the water through the movement of the rotor, and makes a uniform suspension. However, due to the singleness of the working mode and structure of the current pulper, the following problems are caused: First, the efficiency is low. The existing pulper realizes pulping through the mechanical collision between the feed liquid and the rotor and the barrel wall, and the power of the collision comes from the rotor. For the agitation of the liquid material, in the process of pulping, part of the energy is consumed in the reactive power loss of the machine, so the efficiency of mechanical pulping is very low; secondly, the energy consumption is large and resources are wasted. During the working process, not only must the fluid be driven to rotate, but also the resistance of the fluid must be overcome, which consumes a large amount of mechanical energy to a certain extent.
因此，针对现有碎浆机在使用中普遍存在的效率低、能耗大等问题，应从碎浆机工作方式及结构上进行综合考虑，设计出碎浆效率高且能耗低的一种制浆设备。 Therefore, in view of the common problems of low efficiency and high energy consumption in the use of existing pulpers, it is necessary to comprehensively consider the working mode and structure of the pulper, and design a system with high pulping efficiency and low energy consumption. slurry equipment.
