The utility model has the advantages that:

(1) the utility model discloses a two kinds of different materials get into behind bucket conveyor equipment and correspond the blanking fill, fall the conveyer belt after falling the tee bend again on, by the conveyer belt transport workshop, this in-process is from the feed bin feed accuracy of exerting oneself uncontrollable, but exerts oneself after bucket conveyor 2 and realized the accurate ratio of bulk material of different feed bins.

(2) The system can realize accurate proportioning of different bulk materials, and has wide application range and simple operation. The system can save the weighing link, thereby achieving the characteristics of cost saving, convenient maintenance and the like.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The utility model provides a system capable of realizing accurate proportioning of bulk materials, which is used for proportioning multiple materials. The system comprises at least two bulk material bins, wherein openings at the upper parts of the at least two bulk material bins are used for loading materials, bin outlets are formed at the lower parts of the at least two bulk material bins and are used for discharging materials, the bin outlets of each bulk material bin are connected with respective material collecting bins 5, a bucket type conveyor belt is arranged in each material collecting bin 5, the feeding end of each bucket type conveyor belt 2 is arranged in each material collecting bin 5, and the discharging end of each bucket type conveyor belt 2 is arranged above a conveyor belt 6.

Go out the bin outlet and gather materials and have material transfer passage between the storehouse 5, lay the hopper that the volume is the same on the bucket conveyor 2, material in the material storehouse 1 enters into the storehouse 5 back through the bin outlet, take the material to the discharge end through all being the hopper on the conveyer belt 2, the discharge end is lifted the material off, because the volume of every hopper is the same, consequently can be according to the composition ratio that the material of difference needs, calculate bucket conveyor's speed, and then the rotational speed through controller control bucket conveyor, make the material can accurate ratio.

A mixing device is arranged above the conveying belt 6, and the mixing device is generally a multi-pass device.

In the embodiment shown in fig. 1, the bulk material bin 1 includes two bulk material bins, in this case, the mixing device is an inverted tee 7, two openings of the inverted tee 7 respectively face to the lower part of the discharge ends of the two bucket type conveyor belts 2, and the third opening of the inverted tee 7 faces to the conveyor belt 6.

When the bulk material proportioning system in the embodiment shown in fig. 1 is in operation, two different materials are respectively corresponding to the bulk material bin 1 i and the bulk material bin ii 4, the materials are discharged into the collecting bin 5 through the material conveying channel between the bin outlet and the collecting bin 5, and the collecting bin 5 is provided with a bucket conveyor 2 device, and the rotation direction is shown in fig. 1. The bucket conveyor 2 is uniformly provided with hoppers with the same volume, the bucket conveyor 2 is driven by a variable frequency motor, the rotating speed of the variable frequency motor is adjustable, and the frequency of the motor is adjusted according to the required proportion of different materials, so that the speed of the bucket conveyor is adjusted.

For example:

if the rotating speed of the bucket conveyor I is n1, the volume V of the hoppers, the number S of the hoppers and the material density rho 1 are adopted.

The output T1= n1 × S × V × ρ 1 of the bucket conveyor a; where n1 is an adjustable variable and S, V, ρ 1 are constants.

A force T2= n2 × S × V × ρ 2 of the bucket conveyor B; where n2 is an adjustable variable and S, V and ρ 2 are constants.

The total output of the system is T = T1+ T2;

the material proportioning coefficient is T1: t2, the constant rotating speed n is constant corresponding to the constant T1 and T2, so the proportioning proportion is constant.

Two different materials enter the corresponding blanking hopper 3 after passing through the bucket conveyor device, fall onto the conveying belt 6 after passing through the inverted tee joint 7 and are conveyed to a production workshop through the conveying belt 6, the feeding output precision of the material bin is uncontrollable in the process, but the output of the material bin is constant at a certain rotating speed after passing through the bucket conveyor 2, so that the accurate proportioning of the bulk materials of different material bins is realized.

The above-mentioned precision is relative precision, non-absolute precision.
