Description

用于降尘的弧扇喷嘴 Dust fan nozzle for arc

技术领域 FIELD

[0001] 本发明涉及用于降尘的弧扇喷嘴,尤其适用于钻头、掘进机截割头、采煤机滚筒、转载点、煤仓、采石场等产尘作业地点的粉尘防治。 [0001] The present invention relates to a dust arcs fan nozzle, especially for a drill bit, roadheader cutting head, shearer drum dust prevention, reproduced point, bunker, quarry dust production job sites and the like.

背景技术 Background technique

[0002] 在工业领域,粉尘对人体健康、生产安全、产品质量、经济效益等诸多方面产生不良影响,一直是国家关注的重大问题,特别是对于矿山生产来说,粉尘职业病危害更是国家粉尘治理工作中的重点和难点。 [0002], dust adversely affect many aspects of human health, safety, product quality, economic efficiency in the industrial field, has been a major issue of national concern, particularly for mine production, the occupational hazards of dust and more dust is a national the important and difficult work of governance. 近年来,每年新发尘肺病达1万例,截至2011年底,全国煤矿企业累计尘肺病患者31.2万例,尘肺病检出率高达7.2%。 In recent years, annual new-onset pneumoconiosis up to 10,000 cases by the end of 2011, the national coal mine enterprises amounted to 312,000 cases of pneumoconiosis patients with pneumoconiosis detection rate of up to 7.2%. 专家预计今后10年至15年我国尘肺病发病总数还将呈继续上升趋势。 Experts predict that the next 10 to 15 years will total incidence of pneumoconiosis was to continue to rise.

[0003] 为了防治粉尘,我国工业领域采取通风除尘、喷雾降尘等技术手段。 [0003] In order to combat dust, take our industry ventilation and dust, spraying dust and other technical means. 对于喷雾降尘来说喷嘴是喷射装备核心部件,目前常见的喷嘴的流型主要有实心锥、空心锥、平扇等,其中在钻头、截割头等在钻割作业中比较常见的喷嘴是实心锥和平扇喷嘴。 For spray nozzle for dust core member is injection equipment, the current common flow type nozzle mainly full cone, hollow cone, flat fan, etc., wherein the drill bit, the drill cutting top cutting operation is more common solid cone nozzle peace fan nozzle. 这些喷嘴存在的主要问题是用水效率低,不能充分包裹产尘点,在水量一定时,覆盖面积小,进而会带来一系列负面问题。 The main problem is the low efficiency of water nozzle can not be fully wrapped in dust production point, when a certain amount of water, cover a small area, and thus will bring a series of negative issues. 以煤矿为例:煤矿井下采掘作业时主要采用掘进机,而掘进机的截割头较大,一般需要大量喷射水雾才能将截割头完好的包裹,这就造成了用水过度,恶化了作业环境,而且随着用水的增多还会导致煤的发热值降低,影响煤的品质。 Coal mine as an example: boring machine used mainly when coal underground mining operations, while the roadheader cutting head large, generally requires a lot of water sprays to the head intact cutting package, which resulted in excessive water, the deterioration of the job environment, and with the increase of water will lead to lower calorific value of coal, affecting the quality of coal. 特别是在某些底板为吸水性软岩的掘进工作面,底板会由于降尘用水过多而造成湿软塌陷,往往影响正常的采掘进度和安全生产。 Especially in certain floor is heading face-absorbent soft rock, dust the floor due to excessive water caused the collapse marshy, often affect the normal progress of mining and production safety. 因此,为了提高防尘用水效率,防止防尘用水过量,保障降尘效果,急需发明新型喷头。 Therefore, to improve the efficiency of dust water, excess water to prevent dust, dust protection effect, the invention of new head urgently needed.
