Description

Technical Field

[0001] The invention relates to the technical field of alloy ore equipment, and in particular to a method for using an automatic package tearing, sampling, screening and crushing system for alloy ore. Background Art

[0002] The existing alloy ore screening method is: manually pour the bagged alloy ore out of the bag, and then randomly take out some samples from the material pile. Then pour the taken out samples into the fixed-ratio divider to reduce and divide some samples, and then crush the reduced samples. A large amount of remaining materials are manually put into the material bag and put back to the original place. This screening method has a low degree of automation and mostly relies on manual sampling and screening, which has the disadvantages of high labor intensity, low efficiency, and non-representative sampling.

[0003] In view of the shortcomings of existing alloy ore screening methods such as low degree of automation, high labor intensity, and weak sampling representativeness, we have developed and invented an intelligent alloy ore screening system with high degree of automation, good sampling and reduction representativeness, and automatic mechanical functions such as weighing, screening, waste material recovery and bagging, which greatly reduces labor intensity. Summary of the invention

[0004] The object of the present invention is to provide a method for using an automatic bag tearing, sampling, screening and crushing system for alloy ore to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: a method for using an automatic bag tearing, sampling, screening and crushing system for alloy ore, comprising an electric hoist, a bag tearing machine, a weighing uniform feeding scale, a sample hoist, a uniform feeder, a reciprocating reducer, an electric tee, a four-stage drum screen, a crusher, a particle size analysis scale, a collection and discarding belt conveyor, a material receiving trolley and an electrical control system. The whole set of equipment realizes mechanical feeding, automatic bag tearing, weighing, uniform feeding, lifting, reduction, screening, crushing, material collection and packaging. All work is automatically completed without manual operation, which greatly saves manpower. The steps of using an automatic bag tearing, sampling, screening and crushing system for alloy ore are as follows:

[0006] A. After the sample is transported to the area to be tested, it is lifted to the top of the bag tearing machine by an electric hoist;

[0007] B. Tear the packaging bag open with a bag tearing machine;

[0008] C. Then weigh it using the weighing and uniform feeding scale under the bag tearing machine;

[0009] D. Feed the weighed samples into the sample elevator evenly in batches;

[0010] E. The sample elevator lifts the sample to the sample preparation height and temporarily stores the material in the uniform feeder;

[0011] F. The system automatically completes the following three modes of sample preparation as required;

[0012] Three sample preparation modes can be set:

[0013] 1) Sampling and particle size testing

[0014] At the discharge port of the uniform feeder, the component sample is collected through a reciprocating reducer, and then the sample enters the adjustable divider, and the final required component sample is reduced by the divider. The component sample slides out through the chute, and the excess sample is discarded to the collection and discarding belt conveyor through the discard chute. The remaining materials after sampling are all screened through the electric tee to screen out samples of four particle sizes of <10mm, 10-50 mm, 50-70mm, and >70mm. The samples are weighed on four particle size analysis scales respectively, and the weighing data is automatically transmitted to the computer system. The computer system automatically analyzes the proportion of each particle size according to the weighing results, and automatically saves the data, which can be uploaded through the network and queried by time. The weighed materials are automatically discarded to the collection and discarding belt conveyor, and are sent to the packaging area on the receiving trolley through the collection and discarding belt conveyor for packaging.

[0015] 2) Take only component samples:

[0016] At the unloading place of the uniform feeder, the component sample is collected through the reciprocating reducer, and then the sample enters the divider, and the final required component sample is reduced by the divider.

The computer system automatically analyzes the proportion of each particle size according to the weighing results and automatically saves the data. The data can be uploaded through the network and can also be queried by time. The weighed materials are automatically discarded to the collection and discarding belt conveyor, and are sent to the packaging area on the receiving trolley for packaging through the collection and discarding belt conveyor.

[0019] Preferably, the bag tearing machine includes a bearing seat, a sealing plate, a cutter, a shaft, a collection box, a coupling and a reducer. The coupling is driven by the reducer, so that the shaft rotates through cooperation with the bearing seat. The cutter is used to tear the packaging bag, the sealing plate prevents the material from splashing, and the collection box is used to collect the torn material. The double-axis reverse rotation is adopted, and the cutter adopts a diamond bending structure to ensure that the bag tearing is more reliable.
