Abstract
The utility model relates to an electronic belt weigher used to measure the output of mineral products, which comprises a frame, a load receptor supported on both ends of the frame and weighing idlers mounted on the load receptor; wherein, both ends of the frame is longitudinally extended outwards along the frame to form the transitional sections of the frame; and at least one group of transitional idlers are mounted on each transitional section of the frame. The electronic belt weigher can match various non-standard belt conveyers, while the measuring accuracy of the electronic belt weigher is not affected, therefore the application range of the electronic belt weigher is widened, and in particular, the electronic belt weigher can also be normally used in rugged environments such as the mining industry including coal mines, concentration plants, the mineral product processing industry, etc.
Description
Technical field
The utility model relates to a kind of belted electronic balance that is used to measure output of mineral product.
Background technology
Belted electronic balance and band conveyor are complementary, and are used for the material that the measuring belt conveyor is carried.Belted electronic balance mainly comprises framework, be supported on the carrier at framework two ends, be installed in weighing carrier roller on the carrier, be installed in crossbeam on the framework etc., carrier is supported on the framework two ends and realizes (double lever weighing frame) by bearing, perhaps on framework, the other end then is supported on (simple lever weighing frame) on the framework by sensor to an end by seat supports.The flute profile carrying roller that described carrying roller is made up of three carrying rollers, wherein, it is consistent that the formed groove angle of flat idler axis of the inclination carrying roller of both sides and central bottom and band conveyor (being complementary with this band conveyor when belted electronic balance uses) are gone up the conveying carrying roller, be generally 30 °, the inclination carrying roller is consistent with the length of flat idler, distance between the conveying carrying roller on distance between per two groups of flute profile carrying rollers and the band conveyor is consistent, is generally 1～1.2 meter.Be that belted electronic balance is installed on the band conveyor during use, and allow the belt of band conveyor be supported on the weighing carrier roller of belted electronic balance and transmission thereon, thereby the material through belted electronic balance is realized metering.
Mostly band conveyor on the industrial production line is to manufacture and design by national standard, and its operation conditions is better, and equipment has the special messenger to safeguard, so the environment for use of belt conveyer scale and effect are more satisfactory.But in the mine, the employed band conveyors of industry such as small-sized ore dressing plant, colliery are nonstandard product mostly, intensity is low, distortion is big, special-shaped carrying roller is many.These industries output when producing is subjected to multiple factor affecting, at any time change, the flow rate fluctuation of material is very big, small-sized factory ore dressing plant flow is generally on the low side, and poor working environment, particularly after belted electronic balance is installed on the band conveyor, conveying carrying roller adjacent with belted electronic balance and the relative position between the weighing carrier roller on the belted electronic balance are difficult to be guaranteed (under the ideal state on the band conveyor, two kinds of carrying rollers should be on the same straight line on the mass transport direction, and the flat idler in the carrying roller is positioned at same plane), this will have a strong impact on the metering of belted electronic balance to convey materials, so its measuring accuracy was very low when existing belted electronic balance used under this environmental baseline, the failure rate height.
The utility model content
The purpose of this utility model provides a kind of mining area belted electronic balance, the measuring accuracy when using under environment of mining area to improve it.
Mining area described in the utility model comprises framework, is supported on the carrier at framework two ends with belted electronic balance, and be installed in weighing carrier roller on the carrier, the framework two ends vertically stretch out along framework and form the framework transition section, and one group of transition carrying roller is installed on each segment frames transition section at least.
Between the weighing carrier roller, between the transition carrying roller, and the distance between weighing carrier roller and the transition carrying roller less than and the conveyor of belted electronic balance coupling on the conveying carrying roller between distance, be to carry 1/3～4/5 of distance between the carrying roller.
The groove angle of weighing carrier roller and transition carrying roller less than with the band conveyor of belted electronic balance coupling on the groove angle of conveying carrying roller, can be little 5 °～15 °.
The length of the flat idler in described weighing carrier roller and the transition carrying roller is greater than the length of two inclination carrying rollers.
Below framework and framework transition section, be provided with height-adjustable feet.
Has the framework transition section that the transition carrying roller is installed at the framework two ends, after belted electronic balance is installed on the band conveyor, the transition carrying roller is located between the weighing carrier roller of the conveying carrying roller of band conveyor and belted electronic balance, like this, the carrying roller adjacent with weighing carrier roller (being the transition carrying roller) concerns requirement with the position of weighing carrier roller, particularly it is on same straight line, and the requirement in same plane can accurately be guaranteed by machine-building, after having avoided existing belted electronic balance to be installed on the band conveyor, the problem that relative position is difficult to guarantee between conveying carrying roller adjacent with weighing carrier roller and the weighing carrier roller, thus the measuring accuracy of belted electronic balance is greatly improved.
Between the weighing carrier roller, between the transition carrying roller, and the distance between weighing carrier roller and the transition carrying roller less than and the conveyor of belted electronic balance coupling on the conveying carrying roller between distance, can reduce to be loaded with the winding degree of the belt of material like this, thereby reduce the influence of belt tension the belted electronic balance measuring accuracy.
The groove angle of weighing carrier roller and transition carrying roller less than with the band conveyor of belted electronic balance coupling on the groove angle of conveying carrying roller, at convey materials after a little while, applying (contact) degree of belt and weighing carrier roller can be increased, the measuring accuracy of belted electronic balance can be effectively improved.
The length of the flat idler in weighing carrier roller and the transition carrying roller is greater than the length of two inclination carrying rollers, can increase applying (contact) degree of the flat idler in belt and the weighing carrier roller, can effectively improve the measuring accuracy of belted electronic balance.
Below framework and framework transition section, be provided with height-adjustable feet, belted electronic balance can be placed in the framework of band conveyor like this, adjusting by feet guarantees the conveying carrying roller relative position in vertical direction on weighing carrier roller on the belted electronic balance, transition carrying roller and the band conveyor, thereby the existing belted electronic balance of change must directly be fixed on the mounting means (should not be directly installed under the occasion of carrying on the frame at the belt conveyer scale framework, adopt this mode) on the band conveyor.
Belted electronic balance described in the utility model is owing to have this kind structure, it can be complementary with various nonstandard band conveyors and not influence its measuring accuracy, increased the usable range of belted electronic balance, particularly in mine excavations such as colliery industry, the abominable occasions of environment such as ore dressing plant, mineral products processing industry also can normally be used.
