Description
The present invention's " large-tip angle and belt conveyor with baffle chain " belongs to the continous way Transport Machinery, and the high spud angle that is specially adapted to bulk material tilts to transport.
The existing bulk material Transport Machinery of transportation continuously that is used for can be divided into two types of belt transportation and chain type transportations.For example common universal sealing-tape machine, shallow/deep groove type sealing-tape machine and external advanced press belt type transport plane, snakelike clipping transport plane, the clipping transport plane of machinery pressurization all belong to the ribbon conveyer tool.With universal sealing-tape machine is example, and the mechanism that it transports bulk material is by the contact friction force between bulk material and the bearing material adhesive tape, follows the bearing material adhesive tape by bearing material adhesive tape drive contact layer material and moves together; The upper materials that contacts with the bearing material adhesive tape is not the internal friction drive by bulk material, moves with the contact layer material.Because the bearing material adhesive tape is having sagging to exist (with sagging component the f=((q+q on the perpendicular direction of carriage direction between the two adjacent carrying roller groups

0: the linear meter(lin.m.) weight of bulk material, q: bearing material adhesive tape linear meter(lin.m.) weight, α: transport plane angle of inclination, L
P: carrying roller group spacing, H: bearing material adhesive tape tensile force.Since the material on the bearing material adhesive tape cross before and after the carrying roller along with the perpendicular direction of carriage direction on speed from the occasion of sporting negative value, material is produced beat, material is loose from phenomenon with the appearance of bearing material adhesive tape, this moment storeroom bump and rub displacement, consumed the kinetic energy of material itself, material is reduced along the speed of carriage direction, and the bearing material adhesive tape is the body that travels at the uniform speed, show as the relative slippage of material, therefore when transportation volume calculates, have velocity coefficient the bearing material adhesive tape.When the transportation inclination angle increases, the sliding force of bulk material increases, and material reduces the positive pressure of bearing material adhesive tape, make the bearing material adhesive tape reduce along the drive of haul direction to material, when material is crossed carrying roller, the bearing material adhesive tape increases to the time gap that recovers normal drive from the drive of forfeiture to material, and skidding distance increases relatively, has occurred the inclination angle coefficient when calculating transportation volume again.This universal sealing-tape machine generally is used for the level transportation or the inclination angle is not more than 14 ° small inclination inclination transportation.Be to adapt to the high spud angle transportation of tilting, country such as the U.S. and Russia develops press belt type, snakelike clipping, the clipping transport plane of machinery pressurization in recent years.These three kinds of transport planes on haul mechanism, have common characteristic, promptly by variety of way, to the pressurization of the levels adhesive tape of splendid attire bulk material, strengthen the pressuring action of adhesive tape to bulk material, the internal friction of the contact friction force of adhesive tape and bulk material and material is increased, thus can be at the high spud angle condition transportation bulk material that has a down dip.Because the adhesive tape of this class transport plane still will move on carrying roller, in reason, still exist and similarly shelter disease with universal sealing-tape machine, only degree is lighter.These three kinds of ribbon conveyers all need be used the high strength adhesive tape, the levels adhesive tape respectively by separately actuating device drive, very high to the synchronous requirement that drives, in addition material lumpiness degree of uniformity is had higher requirement, the material lumpiness can not be too big.The advantage of ribbon conveyer is that resistance coefficients is little, is about 0.03～0.04.
Scraping transporter, buried scraper conveyor belong to the chain conveyor tool.This class transport plane all need have a fixed conveying trough, scraper plate on scraper chain towing bulk material in conveying trough also need overcome friction drag, running resistance is sizable, with the fortune coal is example, the haul drag coefficient is 0.45～0.6, and it is just very big to add the total drag coefficient of chain drag coefficient, equipment.Chain conveyor is (as scraping transporter, buried scraper conveyor) though also can be used for tilting transportation, but also exist and much shelter disease, except that running resistance is big,, limited transport capacity because scraper plate and material and conveying trough frictional heat scraper plate running velocity can not be too high, conveying trough and scraper plate abrasion are very fast, conveying trough requires hard matter wear-resisting, straight smooth, so equipment investment is big, the traffic cost height.Advantage is that plant capacity is bigger because of the employing chain-driving.
The object of the present invention is to provide a kind of conveying efficiency height, equipment cost and traffic cost be low, can be for the tilt continous way Transport Machinery of transportation bulk material of high spud angle.
The present invention realizes like this.Large-tip angle and belt conveyor with baffle chain is not made up of with the cover tape loop of actuating device with the bearing material ribbon conveyer loop of actuating device and one a baffle plate chain loop that has an actuating device, one, and three loops are independent of each other.Referring to accompanying drawing 1, another kind of structural shape is a tape loop with cover not, referring to accompanying drawing 2.In accompanying drawing 1 and the accompanying drawing 2,1 is conduction chain (available fork-shaped chain, leaf chain, roller chain) the 2nd, baffle plate (available metal, plastics, rubber plate is made), 3,4 is that carrying roller (can be a flat pattern, shallow/deep groove type, grooved, the cast carrying roller), the 5th, conveyer belt (available adhesive tape, canvas belt, plastic tape, metal tape), the 6th, cover tape (available rubber tape, canvas belt, plastic tape, metal mesh belt, the fiber guipure), 7,8,9,10 are changed course cylinder (selecting serial cylinder for use), the 11st, a wheel, (available minor diameter sprocket wheel or halo), the 12nd, pinch roller (selecting minor diameter sprocket wheel or halo for use), the 13rd, drive sprocket, the 14th, the changed course sprocket wheel, the 15th, charging hopper (the conveyer belt amalgamation that should be installed in baffle plate on the baffle plate chain and kerve bearing material is local preferably), the 16th, stripper, the 17th, bulk material (abbreviation material), the 18th, electrical motor and reductor, the 19th, sprocket wheel polygon effect abatement device.The baffle plate chain loop of apparatus of the present invention is made up of conduction chain 1, baffle plate 2, pinch roller 12, drive sprocket 13, changed course sprocket wheel 14.The cover tape loop is made up of carrying roller 4, cover tape 6, changed course cylinder 7 and 10.Bearing material ribbon conveyer loop is by carrying roller 3 and 4, and conveyer belt 5, changed course cylinder 8 and 9 are formed.Baffle plate 2 on conveyer belt 5 on the bearing material ribbon conveyer loop and the baffle plate chain loop by the baffle plate chain deadweight prolong form the appearance body space of filling material between the amalgamation of journey conformal, the two adjacent baffle plates, referring to accompanying drawing 2 and accompanying drawing 3.When need during with the cover tape loop, cover tape 6 is prolonged the appearance body space of the filling material of the amalgamation of journey conformal, two adjacent baffle plates, cover tape 6, the another kind of pattern of conveyer belt 5 formation by deadweight and the baffle plate upper edge on the baffle plate chain, referring to accompanying drawing 1 accompanying drawing 3.
When no-load run, conveyer belt 5 and cover tape 6 by with the baffle plate chain on the contact friction force of baffle plate 2, realize and the synchronized operation of baffle plate chain.When transporting material, be subjected to the contact friction force of material 17 and conveyer belt 5 under baffle plate 2 thrust, also participated in drive to conveyer belt 5, this moment to the drive of conveyer belt 5 during than zero load the drive of 2 pairs of conveyer belts 5 of baffle plate much bigger, be so that material 17, conveyer belt 5 and baffle plate chain three synchronized operation.When to the drive of conveyer belt 5 when enough big, the discharging section of bearing material ribbon conveyer just can extend a segment distance by along continuous straight runs.Referring to accompanying drawing 1.What take place when material is crossed carrying roller in the haul process beats and haul velocity variations that the sprocket wheel polygon effect causes, can only make the material in the appearance body space become more closely knit and sliding phenomenon does not take place, realize material 17 and baffle plate chain, conveyer belt 5, cover tape 6 synchronized operations.If the velocity variations that causes because of the sprocket wheel polygon effect is limited in the small range, the angle of repose of the material in the motion is remained on the bigger numerical value, packing factor is increased, haul is effective.As need increase propulsive effort in the centre and brake equipment is set greatly because of transportation range the time, two tow chains can be arranged in the both sides of conveyer belt 5.Referring to accompanying drawing 4.
Large-tip angle and belt conveyor with baffle chain is compared with existing ribbon conveyer tool, and many advantages are arranged:
(1) type of drive of apparatus of the present invention is chain-drivings rather than big by the frictional transmission so the transmission power of friction roll.
(2) warp tension ratio that bears of the conveyer belt on the bearing material ribbon conveyer loop is less, can select normal tape for use, and transport plane length is not subjected to the restriction of conveyer belt intensity.
