Description

Technical Field

[0001] The utility model relates to the field of coal bunkers, in particular to an anti-bunkering belt feeder. Background Art

[0002] A coal bunker refers to a place for temporary storage of coal at the bottom of a coal mine, a coal preparation plant, a power plant, a coking plant, etc. During the production process, it is mainly used as a container for placing raw coal. Small raw coal bunkers under coal mines mainly serve as buffer bunkers, while large coal bunkers mainly serve as storage. After all, raw coal bunkers are used to transfer coal. They have coal input and output ports. Ensuring the normal operation of the raw coal bunker is of paramount importance in coal production, transportation, storage, and other links! Coal mine conditions are relatively poor. When there is a lot of water in the coal bunker, especially when the bunker opening is closed for a long time, a large amount of coal water and coal slime will accumulate in the coal bunker. When the coal water and coal slime move to the bunker opening, the coal water and coal slime will instantly pour down, like a mudslide, gushing out in large quantities in a short period of time, forming a coal slime flow, causing bunker leakage accidents. In mild cases, equipment will be buried, and in severe cases, a large number of casualties will be caused.

[0003] Therefore, it is necessary to develop a new type of anti-storage belt feeder to avoid the occurrence of storage accidents. Utility Model Content

[0004] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, the utility model provides an anti-storage belt feeder to effectively avoid the occurrence of storage accidents and avoid accidents.

[0005] Technical solution: The utility model is an anti-channeling belt feeder, which is characterized by comprising an AI camera, a feeder, a gate, a hydraulic station and an electrical controller. The AI camera is arranged in front of the outlet of the feeder, the feeder and the hydraulic station are connected to the electrical controller, and the hydraulic station is connected to the gate of the feeder.

[0006] The hydraulic station includes an oil tank, an oil suction filter, an oil pump, a one-way valve, a pressure gauge, a reversing valve and an oil cylinder which are connected in sequence.

[0007] Wherein, the oil tank is provided with a liquid level gauge and an air filter.

[0008] Wherein, the oil pump is connected to the electric motor.

[0009] Wherein, the pipeline between the oil pump and the one-way valve is connected to the oil tank through a branch provided with an overflow valve.

[0010] Wherein, the oil cylinder is connected with the gate.

[0011] Wherein, the piston rod of the oil cylinder is connected to the gate plate of the gate.

[0012] Beneficial effects: Compared with the existing technology, the utility model has the following significant advantages: The utility model captures the coal flow image at the outlet of the feeder through an AI camera. The image is recognized and processed through multiple algorithms such as image edge detection method and threshold segmentation method. When a large amount of coal water and coal slime is found to be gushing out at the outlet of the feeder and exceeds the safety threshold, an instruction is immediately issued to the electrical controller, the electrical controller starts the motor of the hydraulic station, the oil pump outputs high-pressure oil, and the reversing valve controls the action of the oil cylinder. The piston rod of the oil cylinder drives the gate plate to move, so that the gate is closed and the coal water and coal slime are prevented from continuing to gush out; it effectively avoids the occurrence of bunker accidents and avoids the occurrence of accidents.

DETAILED DESCRIPTION

[0017] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0018] The anti-channeling belt feeder of the present invention includes an AI camera 1, a feeder 2, a gate 3, a hydraulic station 4, and an electrical controller 5. The AI camera 1 is located in front of the outlet of the feeder 2. The feeder 2 and the hydraulic station 4 are connected to the electrical controller 5. The hydraulic station 4 is connected to the gate 3 of the feeder 2. The hydraulic station 4 includes an oil tank 401, an oil suction filter 404, an oil pump 405, a one-way valve 406, a pressure gauge 407, a reversing valve 408, and an oil cylinder 409, which are connected in sequence. The oil tank 401 is equipped with a liquid level gauge 402 and an air filter 403. The oil pump 405 is connected to an electric motor 411. The pipeline between the oil pump 405 and the one-way valve 406 is connected to the oil tank 401 via a branch line equipped with a relief valve 410. The oil cylinder 409 is connected to the gate 3. The piston rod of the oil cylinder 409 is connected to the gate plate of the gate 3.

[0019] Working Principle: A mine AI camera 1 is installed in front of feeder 2 to monitor the coal unloading situation of feeder 2. AI camera 1 captures the coal flow at the outlet of feeder 2. The image is recognized and processed using various algorithms such as image edge detection and threshold segmentation. When a large amount of coal water and coal slime is detected gushing out from the outlet of feeder 2 and exceeds the safety threshold, a command is immediately issued to the electrical controller 5. The electrical controller 5 activates the motor 411 of the hydraulic station 4, and the oil pump 405 outputs high-pressure oil. The oil cylinder 409 is controlled by the reversing valve 408, and the piston rod of the oil cylinder 409 drives the gate plate of the gate 3 to close the gate 3, preventing the coal water and coal slime from continuing to gush out and avoiding accidents. The closing degree of the gate 3 is reasonably controlled according to the amount of coal water and coal gushing out, and dynamic monitoring is implemented.

[0020] After motor 411 is activated, oil pump 405 operates, and hydraulic oil passes through oil suction filter 404. Oil pump 405 then delivers high-pressure hydraulic oil. This high-pressure hydraulic oil then flows through check valve 406 and reversing valve 408, driving the piston rod of oil cylinder 409 to extend and retract, thereby moving the gate plate and opening and closing gate 3. Relief valve 410 controls system pressure. Pressure gauge 407 displays system pressure.
