The high angle belt conveyor refers to the belt conveyor with an angle of 18 ~ 90 degrees. The special general belt conveyor can't carry materials, and the transportation will fall automatically or be limited in space. It can only be transported by baffle belt, with the transmission characteristics of high angle. The structure is compact and the floor area is small. It is an ideal equipment for the high angle transportation and vertical lifting of materials. Underground mining and underground engineering, open-pit mining are adopted C-type self unloading ship machinery and other fields.

　　高傾角帶式輸送機(jī)的特點(diǎn)是用波浪型護(hù)舷輸送帶代替普通的輸送帶。其工作原理和結(jié)構(gòu)與普通帶式輸送機(jī)相同。輸送帶是基礎(chǔ)帶，隔板與波浪型擋泥板構(gòu)成一個(gè)整體結(jié)構(gòu)。

　　The biggest characteristic of high angle belt conveyor is to replace the ordinary belt with wave fender belt. Its working principle and structure are the same as the common belt conveyor. The conveyor belt is the foundation belt, and the clapboard and the wave type fender form an integral structure.

　　我國大型斜帶機(jī)的除塵方式多采用集中負(fù)壓負(fù)壓袋式除塵。

　　In China, most of the dedusting methods of large inclined belt machine are concentrated negative pressure bag dedusting.

　　袋式除塵采用集塵罩、輸送管、袋式除塵器、感應(yīng)風(fēng)機(jī)和煙囪。缺點(diǎn)是投資大;集塵率低;水平管線容易堵塞，影響捕獲率。排氣量大，運(yùn)行成本高;除塵器、引風(fēng)機(jī)、煙囪罩面積大;管道復(fù)雜，主管徑大，支管多，管道長;系統(tǒng)中閥門較多，系統(tǒng)空氣平衡調(diào)節(jié)復(fù)雜。需要配備專職運(yùn)維人員和粉塵輸送設(shè)備。

　　Bag type dedusting adopts dust collecting cover, conveying pipe, bag type deduster, induction fan and chimney. The disadvantages are large investment, low dust collection rate, easy blockage of horizontal pipeline, which affects the capture rate. Large exhaust volume, high operation cost; large area of dust remover, induced draft fan and chimney cover; complex pipeline, large main pipe diameter, many branch pipes, long pipeline; many valves in the system, complex air balance regulation of the system. Full time operation and maintenance personnel and dust conveying equipment are required.

　　目前，大傾角帶式除塵的難點(diǎn)在于粉塵的收集和輸送。導(dǎo)帶槽上設(shè)有錐蓋，與輸送粉塵的管道相連接。為了避免粉塵溢流閥蓋，導(dǎo)槽必須處于負(fù)壓狀態(tài);為避免管道內(nèi)積塵，必須采用大風(fēng)量輸送。這兩個(gè)因素都需要強(qiáng)大的力量。一旦粉塵沉積，管道內(nèi)部，排氣效率將大大降低，捕集器內(nèi)的負(fù)壓狀態(tài)將被破壞，粉塵將溢出捕集器，捕集器效率將大大降低。采用大傾角袋裝除塵技術(shù)。運(yùn)行1 - 2年后，除塵管道堵塞，除塵系統(tǒng)癱瘓，塵點(diǎn)飛揚(yáng)。另一方面，導(dǎo)槽與波狀擋邊之間沉積了一定量的物質(zhì)和粉塵。當(dāng)皮帶進(jìn)入傾斜角部時(shí)，積累的物料和粉塵會(huì)從皮帶的基帶地板上掉落，造成二次粉塵污染。

　　At present, the most difficult point of large angle belt type dust removal lies in the collection and transportation of dust. The guide belt groove is provided with a cone cover, which is connected with the pipeline for conveying dust. In order to avoid the dust overflow valve cover, the guide groove must be in the negative pressure state; in order to avoid the dust accumulation in the pipeline, large air volume must be used for conveying. Both of these factors need strong power. Once the dust is deposited in the pipeline, the exhaust efficiency will be greatly reduced, the negative pressure state in the catcher will be destroyed, the dust will overflow the catcher, and the efficiency of the catcher will be greatly reduced. The dust removal technology of big angle bag is adopted. After 1-2 years of operation, the dedusting pipeline is blocked, the dedusting system is paralyzed, and the dust point is flying. On the other hand, a certain amount of material and dust are deposited between the guide groove and the corrugated edge. When the belt enters the inclined corner, the accumulated materials and dust will fall from the baseband floor of the belt, causing secondary dust pollution.
