Scraper conveyor scraper conveyor can be used for horizontal transport, can also be used to tilt transport. Transport along the tilted upwards, seam inclination should not exceed 25 °, downward transport, inclination should not exceed 20 °, when the seam inclination is large, you should install anti-skid devices. Flexible scraper conveyor allows for bending 2 ° ~ 4 ° in the horizontal and vertical directions. Working Principle scraper conveyor that will open the chute, as coal, waste rock or piece of material, such as the bear, the blade is fixed on the chain (consisting of scraper chain), as the lead member. When the head of the Ministry of transmission start, drive sprocket shaft rotating head, so that the material driven scraper chain loop runs along the chute to move, until the machine head unloaded. Scraper chain sprocket bypass for stepless closed loop operation, the completion of delivery of materials. Disadvantages: a solid structure. Can withstand coal, waste rock or other material of punch, hit, hit, pressure and other external force. 2, able to adapt to the coal face uneven floor, bending the passage of the need to withstand bending vertical or horizontal direction. 3, the body is short, easy to install. 4, can double as Shearer orbit. 5, can reverse operation, easy to handle end chain accident. 6, can make hydraulic support front fulcrum. 7, a simple structure, at any point on the feed length can feed or discharge. 8, chassis sealed to prevent the transportation of materials when flying dust and pollution of the environment. 9, when its tail is not set chassis and blade insert pile, self-reclaimer delivery. Disadvantages: 1, no-load power consumption is large, about 30% of the total power. 2, not long-distance transport. 3, prone to swap chain, the chain jumping accident. 4, the consumption of steel and more. Large cost. ① development trends continue to large-scale development. Including large-scale aspects of large transport capacity, large single length and large transmission angle and so on. The length of the hydraulic conveying device has reached more than 440 km. Single belt conveyor length of nearly 15 km, and has appeared a number of units consisting of contact B by two places "of the belt conveyor path." Many countries are exploring long-distance, large-volume continuous feed conveyor structure and better materials. ② expanding the use of conveyors. Development can be at a high temperature, low temperature, corrosive, radioactive, flammable substances in the work environment, as well as capable of delivering hot, explosive, agglomerate, sticky material conveyor. ③ so constructed to meet the material handling conveyor automation system control requirements for stand-alone raised. Such as the post office used automatic sorting conveyor car wrapped should be able to meet the requirements for the sorting operation. ④ reduce energy consumption to save energy has become an important aspect in the field of transportation technology research work. One ton of material has been transported one kilometer of energy consumed as an important indicator of the conveyor selection. ⑤ reduce emissions of dust, noise and emissions of various conveyor when the job is generated. Pulse controller pulse controller is the main controller of the pulse jet dust bag filter. Its output signal to control the electromagnetic pulse valve for bag cleaning cycle to ensure that the processing power and dust collection efficiency. Pulse interval of the product, the pulse width of outputs, cycle interval is adjustable, digital display data is available, of outputs can be adjusted according to demand. Most of the products are imported parts, performance is higher than similar products in the market, making the operation more intuitive and easier, more stable performance. Optical isolation products are very good. Uses: mainly used for furnaces, cement kilns, mining and other industries. Features ◆ QYJ series non-contact pulse controller of all imported well-known manufacturers of CMOS integrated circuits and electronic components (TI, ST, PHILIPS, etc.), this circuit has low power consumption, high reliability, strong anti-jamming features to ensure and improve the stability and reliability of the instrument work. ◆ pulse interval and pulse width with stepless adjustment, increasing the pulse interval and pulse width adjustable range, convenience in use and operation. ◆ This series digital controller are used to display the status of each output with low power consumption, high brightness, long life, clear and aesthetic advantages. At the same time the brightest output state with LED indication, visual display, always observe the work of each pulse valve. ◆ controller features an adjustable set of outputs, universal DIP switch "+" "-" to set the controller output according to need large ones, when used arbitrarily select the desired over the entire range of outputs large ones work. ◆ controller output selection super power output tube output, and a surge absorption circuit protection, anti-jamming, fast response, superior stability, excellent quality; load short circuit protection, long service life. ◆ non-contact switch for controlling various solenoid valves and inductive loads, frequent switching quickly without affecting life. ◆ controller can be connected with the pressure signal input interface, when the pressure reaches the set pressure value controller switch is turned on, the control device sequentially injection. ◆ controller power using special processing, high power stability and load stability; output ripple voltage is small; fast transient response; no switching interference; simple circuit structure, easy maintenance. In a variety of electromagnetic interference voltages serious scene but also to ensure long-term stable operation of the control device. ◆ controller shell with project-specific dust sealed transparent plastic chassis, beautiful appearance, easy operation. Bag filter baghouse is a dry dust device. Media use for some time, due to sieving, collision, retention, baghouse diffusion, electrostatic and other effects, the bag surface layer of accumulated dust, this layer is called the primary layer of dust, in this future course of the campaign, First filter layer became the main filter layer, relying on the role of the primary layer, the larger mesh filter can be obtained a high filtration efficiency. With dust accumulated in the filter surface, filter efficiency and resistance increases correspondingly, when the pressure differential across the filter is large, will some tiny dust particles adhering on the filter in the squeeze past, precipitator efficiency. In addition, the resistance is too high dust significantly decreased the amount of wind dust removal system. Therefore, dust resistance reaches a certain value, to timely cleaning. When cleaning the primary layer can not be destroyed, so as not to decrease the efficiency. Works filter dust cloud of dust containing pores means the filter layer through the gas stream to intercept trap dust particles are filtered layer down, in order to achieve solid separation equipment. Filter means comprises a dust bag filter dust collector and the particle layer, the former is usually an organic or inorganic fibers made of fabric filter bags as filter layer, a filter layer which use more different size particles, such as quartz sand, river sand, ceramic, slag and other components. Accompanied by repeated powder bag attached to the outer surface of the powder layer constantly thickening, bag filter resistance value also increased; pulse valve diaphragm issued a directive, at around submerged pulse valve open, high-pressure compressed air within the package through the air, and if there is no dust or small to a certain extent, the mechanical cleaning work will stop working. Advantages ⑴ high collection efficiency, generally above 99%, the outlet gas precipitator dust concentration in the tens mg / m3, the sub-micron particle size for fine dust have a higher efficiency rating. ⑵ handle a wide range of air volume, only a small number of 1min m3, big up to 1min tens of thousands of m3, both for industrial furnace flue dust, reduce emissions of air pollutants. ⑶ simple structure, easy operation and maintenance. ⑷ in ensuring the same high removal efficiency of the premise, the cost is lower than the ESP. When ⑸ glass fiber, PTFE, P84 and other high temperature filter, can run at a high temperature above 200 ℃. ⑹ not sensitive to the characteristics of the dust, and is not affected by the dust resistance.
