Description

TECHNICAL FIELD

[0001] The utility model belongs to material transfer technical field relates to a material transfer unbagging device. BACKGROUND

[0002] At present, most of the concentrates used in copper smelting are ton bags, which are transported to smelting enterprises by train. After all the ton bags arrive, they need to be broken down and then put into the silo. The silo is generally divided into two types: semi-underground and above-ground. The above-ground silo usually uses lifting equipment to lift the ton bags from the train to the ground, and then a semi-circular bag is cut by hand to make the material flow out, and then a shovel loader is used to stack the material in the silo for storage. The semi-underground silo is directly entered by the post personnel, and then the ton bags are lifted from the train to the designated position in the silo by the lifting equipment, and then the post worker performs the bag breaking operation in the silo and is transported by the shovel loader for storage. The common point of the two unloading methods is that the ton bags are lifted to the designated position by the crane, and then the bag is broken by hand, and the shovel loader is used for storage. This manual bag breaking operation method has high labor intensity, and there is a safety hazard when the post worker cooperates with the crane. SUMMARY

[0003] The utility model aims at the problems existing in the prior art, and provides a material transfer unbagging device, which solves the problem that most of the concentrates used in copper smelting are ton bags, the manual bag breaking operation method has high labor intensity, and there is a safety hazard, which threatens the personal safety of the workers.

[0006] An air collecting hood is arranged above the steel bin, the air collecting hood is L-shaped, a plurality of nozzles are arranged on the side wall close to the steel bin, a guide plate is arranged on the side of the air collecting hood, the guide plate is arranged in an inclined manner, and the end of the guide plate is fixedly connected with the steel bin.

[0007] The other end of the air collecting hood is provided with a pipeline, the pipeline is provided with a water pump, the air collecting hood and the water pump are in communication, dust suppression operation is performed, and dust is prevented from flying out during unloading; the electric rotating blade and the water pump are opened and closed synchronously, the power utilization efficiency is improved, and waste is avoided.

[0008] Furthermore, the material guide plate is provided with a paddle-rotating material level meter and an electric rotating blade. The paddle-rotating material level meter senses and drives the silo wall vibrator to work to prevent the silo from bursting. The start and stop of the electric rotating blade is controlled by a travel switch, and manual bag breaking is not required, which reduces the number of personnel on duty and eliminates safety hazards.

[0009] Furthermore, the installation angle of the belt conveyor and the horizontal plane is 4 to 10 degrees, which increases the belt speed and allows the material to be thrown into the form of a material.

[0010] Furthermore, the steel silo and the rod valve are connected by flange bolts.

[0011] The beneficial effects of the present invention are:

[0012] The utility model has a compact structure and adopts automatic cutting operation when cutting ton bags, which reduces the number of employees on the job, eliminates safety hazards, reduces the work intensity of employees on the job, and improves the job environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural diagram of the present utility model.

[0014] In the figure, 1-fixed grid screen, 2-steel silo, 3-silo wall vibrator, 4-travel switch, 5-rod valve, 6-belt conveyor, 7-gas collecting hood, 8-sprinkler, 9-water pump, 10-pipeline, 11-material guide plate, 12-rotary paddle level meter, 13-electric rotary blade. DETAILED DESCRIPTION

[0015] The technical solution of the present invention is described below in conjunction with the accompanying drawings and implementation methods.

[0016] like Figure 1 As shown, a material transfer and bag unloading device includes a steel silo 2, the top of the steel silo 2 is provided with a horizontally arranged fixed grid screen 1, the side wall is provided with a plurality of symmetrically arranged silo wall vibrators 3, a travel switch 4 is provided below the silo wall vibrators 3, and a rod valve 5 is provided near the bottom of the steel silo 2. The steel silo 2 and the rod valve 5 are connected by flange bolts; specifically, the rod valve 5 can adjust the number of rods according to actual production conditions to control the discharge amount.

[0017] A belt conveyor 6 is provided below the steel silo 2. The belt conveyor 6 is installed at an angle of 4° to the horizontal plane, which is convenient for increasing the belt speed and forming a throwing form of the material.

[0018] The upper portion of the steel bin 2 is provided with a gas collecting hood 7, which is in L shape, and is provided with a plurality of spray heads 8 near the side wall of the steel bin 2. The side portion of the gas collecting hood 7 is provided with a material guiding plate 11, which is arranged in an inclined manner and is fixedly connected with the steel bin 2 at the end portion. The opening and closing of the electric rotary blade 13 is controlled by the travel switch 4, so that manual bag breaking is not needed, the number of post personnel is reduced, and the safety hazard is eliminated. In addition, the electric rotary blade 13 is arranged in four groups, so as to ensure the bag breaking precision and improve the bag breaking operation rate.

[0019] The other end of the gas collecting hood 7 is provided with a pipeline 10, which is provided with a water pump 9 and is in communication with the water pump 9. The utility model utilizes the dust suppression operation of the atomizing spray head 8 to prevent dust from being blown out during unloading. The water pump 9 is opened and closed in linkage with the electric rotary blade 13, that is, the water pump 9 is automatically opened after the electric rotary blade 13 is started, so as to improve the power utilization efficiency and avoid waste.

[0020] The material guiding plate 11 is provided with the anti-rotation material level meter 12 and the electric rotary blade 13. When the material in the bin is accumulated to the position of the anti-rotation material level meter 12, the anti-rotation material level meter 12 drives the bin wall vibrator 3 to work, so as to prevent the bin from being filled with material.

[0021] In the use process, the crane hoists the ton bag from the train to the upper material guiding plate 11 of the steel bin 2. The ton bag contacts and inducts the travel switch 4 in the process of sliding downward on the material guiding plate 11, so as to start the electric rotary blade 13. The crane controls the ton bag to descend to the electric rotary blade 13 to cut the ton bag. The material in the ton bag falls to the belt conveyor 6 under the steel bin 2 through the fixed grid sieve 1. The belt conveyor 6 throws the material into the pit. The spray head 8 works to suppress dust in the process of bag breaking and unloading. After the bag breaking is completed, the empty ton bag is transferred to the designated position by the crane. The travel switch 4 inducts to stop the electric rotary blade 13.
