product description

3.2 Sub-resonant impurity removal machine (60-1500mm)

patent name

National patent number

Pulse type spiral material separator

ZL201020191207.9

【working principle】

安装于 皮带机头部滚筒前方或落料斗下方, 来料经过弹性物料导流装置后,将煤流规整成扁平状;煤流自皮带机头部落下,经由减速电机驱动的除杂物机螺旋转主转子,净煤透筛经落料管后进入下一级设备;煤流中的大块矸石、木棒、草垫、破布、麻绳、 编织袋 支护网 等杂物被齿板带出,旋转 至另外一侧时, 经由自动清杂物装置、受 重力作用 落入亚共振机构与多次过滤及回收机构,其中夹杂的碎煤通过回流管重新流至落煤管;而杂物则通过落杂物管、最后落入地面杂物堆积池中。 The sub-resonant impurity removing machine is usually installed in front of the head drum of the belt conveyor or under the falling hopper. After the incoming material passes the elastic material diversion device, the coal flow is regulated into a flat shape; the coal flow comes from the belt head and passes through the reduction motor The driven debris remover rotates the main rotor spirally, and the clean coal passes through the blanking pipe and enters the next level of equipment; large coal vermiculite, wood sticks, straw mats, rags, hemp ropes, woven bags , branches The debris such as the protective net is taken out by the tooth plate. When it is rotated to the other side, it falls into the sub-resonance mechanism and the multiple filtering and recovery mechanism through the automatic debris removal device and gravity . The inclusions of broken coal are recirculated through the return pipe. It flows to the falling coal pipe; and the debris passes through the falling coal pipe and finally falls into the ground debris pool.

【Structure and composition】

落料斗、机架、电气控制系统等组成。 The sub-resonance impurity removing machine is mainly composed of an elastic material regularization mechanism, a sieve tooth separation device, a moment arm floating connection type reduction motor, a fully floating drive roller, an elastic support, a sub-resonance mechanism and a multiple filtering and recovery device, an automatic impurity cleaning device, and a tooth. Plate and roller self-cleaning device, box , falling hopper, frame, electrical control system, etc.

【typical application】

◎ Fine removal of impurities in thermal power plants without dry coal sheds, to remove small debris from sticky wet coal during the rainy season;

◎ The addition or modification of the impurity removal machine of the thermal power plant, due to the site construction, space location, and construction conditions are not conducive to waste removal;

适用于 选煤 厂的 输煤,物料进入洗选系统前 ,除去 大块及杂物 ◎ It is suitable for coal transportation in coal preparation plants . Before the materials enter the washing system , large pieces and debris are removed ;

◎ The coking plant uses water to wash coal to remove impurities. Due to human factors such as transportation and transfer (wood, straw, woven bags, etc.), the inclusion of debris causes system blockage, coal blending, and weighing inaccuracy, which seriously interferes with coal humidity control and coke. Particle size ratio

◎ Coal chemical plant is finely cleaned with water-washed coal. Due to man-made factors such as transportation, transshipment (wood, straw, woven bags, domestic garbage, etc.), contamination caused by contamination causes coal bunkers and separators to jam;

◎ Fine removal of impurities in the raw material preparation workshop of iron-making plant, iron ore powder is easy to adhere when the humidity is high, and it is easy to adsorb magnetically;

◎ Vacuum mining and sorting of iron ore in water can be installed on large mining ships to remove debris such as waterweed, shells, pebbles, etc .;

适用于 焦化 厂的 输煤、配煤、碎煤及筛煤设 备中,除去 杂物 ◎ It is suitable for removing debris in coal transportation, coal blending, crushed coal and coal screening equipment of coking plant ;

[Actual effect]

◎ It is especially suitable for occasions with high requirements for sticky and wet materials, fine impurity removal;

◎ It occupies a small space and can run smoothly and eliminate impurities under the harsh conditions of the site;

以上,杂物中夹带有效物料≤ 0.5% ◎ The impurity removal efficiency can reach more than 95% , and the effective materials entrained in the debris ≤ 0.5% .

[Technical Features]

水分 粘湿物料除 ,并且具有良好的自清理能力; ◎ Adapt to large wooden blocks, large stones, rags, straw, fiber fabrics, hemp ropes, and other sundries, remove impurities from high- moisture sticky materials , and have good self-cleaning ability;

设置有 齿板及滚筒自清扫装置 ,即使 处理粘湿物料时,也不会出现粘料、堵塞、卡滞等现象; Since ◎ plate and provided with teeth cleaning device from the cylinder, even when the materials handling sticky, adhesive material does not occur clogging, catching phenomena;

◎ Due to the setting of a sub-resonance mechanism and multiple filtering and recovery devices, useful materials are fully recovered while removing debris, and no effective materials are entrained.

◎ The vibration frequency, amplitude, and excitation force can be adjusted steplessly within a certain range to adapt to differences in flow and physical properties of materials;

◎ Frequency conversion speed regulation within a certain range of equipment speed to adapt to regional differences such as flow and material properties;

◎ Small footprint and flexible layout: power plants, coking plants, coal preparation plants, coal chemical plants, iron plants, mining ships, etc. can be used;

◎ The equipment has two-stage vibration isolation, low noise, long service life, low installation requirements, and low requirements for the strength level of the building construction;

排放量; ◎ reduce dust pollution, PM2.5 significant reduction in emissions;

◎ Can start with load, variable frequency speed regulation, overload protection;

◎ Can be controlled locally or remotely;

◎ The equipment has a small total power, low power consumption and high cost performance.
