BLT -type scales conveyor structure advantages such as Introduction

Design of the product and its advantages
BLT type conveyor scales by the scale plate device, drive , head wheel device or secondary drive wheel device , part of the tail wheel tensioning devices and metal stents and

other components.
( 1 ) scales board device
Scales shown in Figure 1 90 degree turn conveyor is a carrier member board device and pull the bow conveyor parts, its tank in direct contact with the material , to be able to withstand heavy impact

with steel stamping into a wavy bottom with ribs , with triangular studs reinforcing ribs, so as to have sufficient strength and rigidity. Traction chain 2

For the two 90 degree conveyor bush roller chain , directly exposed to traction. Left and right angle bracket by pulling the chain are connected with 4 1 tank , the tank on both sides of each

section separately fixed a walk round three , walking round with double rolling bearing .
( 2 ) drive means
YJ minute drive YX or type two ( see Figure a, 2b). YX -type drive by the Y series motor 1 , 2 and XEW triangular pulley vice planetary cycloid reducer three components. YJ -

drive device consists of a Y series motor , triangular pulley 2 and vice JZQ reducer 4 components.
( 3 ) tail wheel tensioning device
The chain tensioning means comprises two tail , a long axis and a pair of tension through the screw components. Each rear sprocket are twin scroll
Bearing a tail on the same axle .
Advantages (4) BLT type plate conveyor scales
① walking round slat device built double bearing, low running resistance. As plate width is 1000mm B with old scales board machine , walking wheel diameter D = 180mm, try

running side drag coefficient is 0.13 . BLT series of walking round diameter D = 110mm, testing the drag coefficient is 0.03 .

Run the drag coefficient is reduced by 75 %.
② left and right traction chain and bolted tank , do not use common through shaft , reduce weight . For example plate width B = 800mm, P = 315mm chain link conveyor scales ,

can save steel 30Kg / m. Since the left and right through the shaft without traction chain associated , respectively, with a double tail two sprockets

A rolling bearing fixed on the shaft , a traction chain is only S / 2. S is the total traction. A connection form of the original chain traction should be considered 75% -80 %

of the coefficient of unbalance , the actual traction chain BLT series connection form than the original 20% -25 % .
③ scales board tank made of sheet steel wavy structure , thickness is thinner, use the triangle strengthening ribs and angle , so that the tank light weight, rigidity and

impact resistance. For example, the same as B = 1000mm scales board, old scales board weight is 324Kg / m, while the BLT -type scales board only 175Kg / m, saving

Steel, but also reduces the daily energy consumption .
④ walking round with traction chain arranged separately , easy installation and maintenance scales plate device.
⑤ reducer ratio YX driving device , output shaft allowable torque, it directly through the Oldham coupling with
Head axle joints, the head wheel device and configuration of the entire drive system performance greatly simplified , low cost, easy to install.
⑥ tail wheel tensioner two double sprockets are supported by the end of the axle rolling bearing , not only can reduce the resistance of the drag chain to bypass the rear

sprocket , and two traction chain when not synchronized , the chain can be adjusted automatically .
BLT -type scales conveyor for conveying bulk materials chunks or burning , its structure is characterized by a steel stamping into the tank bottom with wavy wall , there is

sufficient strength and stiffness , traction chain and tank bolt connection , light weight .
The products have been widely used in casting , building materials, mining, paper and other industries, which have been used in the product slat width of most dogs 2400mm,

maximum conveyor length L = 100m, climb a maximum height of 10m. Use of proven , BLT -type conveyor scales reasonable structure, advanced performance. Next

A brief description of its surface structure , the main parameters .
Use BLT type plate conveyor scales
BLT -type scale is a special conveyor slat conveyor , can be used as stationary mechanized transport equipment , transporting heavy bulk material or a single member , in

particular for conveying hot materials chunks or facilitate the transport of material in the process completion of cooling , thousands of dry, heating , cleaning and

Classification processes. Transport can be tilted up or down , in the machinery , chemicals , building materials, metallurgy , power , and mining and other industrial sectors

have broad applicability.
