Description
技术领域 technical field
本实用新型属于粉体材料加工装置技术领域,更具体地说,涉及一种隔音棉粉渣分离装置。 The utility model belongs to the technical field of powder material processing devices, and more specifically relates to a sound-insulating cotton powder and slag separating device.
背景技术 Background technique
旋风收尘器是粉体加工行业应用最普遍的除尘器,它具有结构简单、无运动部件、形式规格多样、可满足不同粒度粉末收集等特点。因此,旋风收尘器被广泛应用于无机非金属矿粉末加工、面粉加工、电厂除尘、木粉加工等领域。旋风收尘器是利用含尘气体沿切线方向进入旋风筒时产生的离心力,使粉尘从气体里分离出来。它没有运动部件,结构简单,造价低,维护方便,耐高温高压,适用于含尘浓度高的情况,传统旋风收尘器的典型结构是:具有切向入口的圆筒及圆锥形成的分离空间。 Cyclone dust collector is the most commonly used dust collector in the powder processing industry. It has the characteristics of simple structure, no moving parts, various forms and specifications, and can meet the collection of powders of different particle sizes. Therefore, the cyclone dust collector is widely used in inorganic non-metallic ore powder processing, flour processing, power plant dust removal, wood powder processing and other fields. The cyclone dust collector uses the centrifugal force generated when the dusty gas enters the cyclone along the tangential direction to separate the dust from the gas. It has no moving parts, simple structure, low cost, easy maintenance, high temperature and high pressure resistance, and is suitable for situations with high dust concentration. The typical structure of a traditional cyclone dust collector is: a cylinder with a tangential inlet and a separation space formed by a cone .
目前,针对隔音棉粉渣的分离筛分装置中普遍存在分离效果不佳,且分离后的粉尘极易排放至大气中,造成环境污染,不利于环保;或者是分离后还需专门设有除尘环保装置,从而提高了设备的成本。如中国专利号为201410100142.5公开了一种落棉回收除渣装置,其包括设置有送风装置的除渣风道,所述除渣风道内设置有驱动器驱动旋转的圆形滤片,所述圆形滤片上均布有小孔且所述小孔的直径小于杂质,所述除渣风道的内壁上设置有收集杂质的环槽,所述圆形滤片滑动设置在所述环槽非进风侧的槽沿上,该专利申请文件中落棉穿过所述圆形滤片,而杂质留在所述圆形滤片上,由于所述圆形滤片的旋转,杂质在离心力的作用下进入所述环槽,除渣过程完成。但是其仍存在如下缺陷: At present, the separation and screening devices for sound insulation cotton powder and slag generally have poor separation effect, and the separated dust is easily discharged into the atmosphere, causing environmental pollution, which is not conducive to environmental protection; or after separation, special dust removal is required Environmentally friendly devices, thereby increasing the cost of the equipment. For example, Chinese Patent No. 201410100142.5 discloses a noil recovery and slag removal device, which includes a slag removal air channel provided with an air supply device, and a circular filter piece driven by a driver to rotate is arranged in the slag removal air channel. Small holes are evenly distributed on the shaped filter sheet and the diameter of the small holes is smaller than that of impurities. The inner wall of the slag removal air duct is provided with a ring groove for collecting impurities. The circular filter sheet is slidably arranged in the ring groove On the edge of the groove on the wind side, the noil in this patent application document passes through the circular filter, while the impurities remain on the circular filter. Due to the rotation of the circular filter, the impurities are under the action of centrifugal force Entering the ring groove, the slag removal process is completed. But it still has the following defects:
1)该专利申请文件中落棉均是经过圆形虑片被过滤除去,而圆形滤片上同时又存在落棉与杂志的混合物,所以穿透效果有限,即分离效果有限,且一次性分离的量较少,分离效率低; 1) In this patent application document, the noil is filtered and removed through a circular filter, and there is a mixture of noil and magazines on the circular filter, so the penetration effect is limited, that is, the separation effect is limited, and the one-time separation The amount is less and the separation efficiency is low;
2)该专利申请文件中杂质均是经过圆形滤片的旋转产生的离心力分离出去,但是同时圆形滤片上又设有立柱,对杂质的离心有一定的阻挡影响,因此降低了分离效果; 2) The impurities in the patent application documents are separated by the centrifugal force generated by the rotation of the circular filter, but at the same time, there are columns on the circular filter, which have a certain blocking effect on the centrifugation of impurities, thus reducing the separation effect;
3)该专利申请文件的设备成本较高,不利于推广使用。 3) The equipment cost of this patent application document is relatively high, which is not conducive to popularization and use.
因此,急需一种分离效果好,利于环保、分离效率高且成本较为低廉的分离装置,即一种一种隔音棉粉渣分离装置。 Therefore, there is an urgent need for a separation device with good separation effect, environmental protection, high separation efficiency and relatively low cost, that is, a sound-proof cotton powder and slag separation device.
