[0032] The preferred embodiments of the present utility model will be described in more detail below. Although the preferred embodiments of the present utility model are described below, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present utility model more thorough and complete, and to fully convey the scope of the present utility model to those skilled in the art.

[0033] As Figures 1-4 shown, a device for blending high-sulfur local ore includes:

[0034] Hopper 1, the hopper 1 includes a cylinder body and a hopper body stacked up and down;

[0035] Vibrator 2, the vibrator 2 is arranged on the outer periphery of the cylinder body;

[0036] Air cannon 3, the air cannon 3 is arranged on the outer periphery of the cylinder body;

[0037] Detection mechanism 4, the detection mechanism 4 is arranged at the discharge end of the hopper 1 or on the batching scale 5 below the hopper 1, and the detection mechanism 4 is communicatively connected to the vibrator 2 and the air cannon 3, and is used to control the opening and closing states of the vibrator 2 and the air cannon 3 according to the discharge state.

[0038] Specifically, the vibrator 2 continuously vibrates the hopper 1 to accelerate the movement of the material, avoid material accumulation, reduce material adhesion, and the detection mechanism 4 detects the discharge state to confirm whether the hopper 1 is blocked. If it is blocked, the air cannon 3 is used to increase the vibration, so as to loosen the material and dredge the blockage of the hopper 1.

[0039] During blanking, the detection mechanism 4 is activated, and the vibrator 2 keeps running. The vibrating hopper 1 prevents materials from sticking to the inner wall of the hopper. When the detection mechanism 4 detects the stop of material output, it indicates material blockage. The air cannon 3 provides greater vibration to loosen the materials through intermittent activation, or only starts the air cannon 3 after blockage for dredging, thereby avoiding material blockage, ensuring stable discharging. Even if blockage occurs, it can be quickly dredged, preventing continuous blockage from causing a large amount of material to be discharged at one time and affecting quantity control.

[0040] Furthermore, for protection, when the air cannon 3 starts, the vibrator 2 can be stopped or the air cannon 3 can be used by synchronously superimposing according to the frequency of the vibrator 2. The air cannon 3 and the vibrator are prior arts. The air cannon 3 utilizes the air power principle, with air as the working medium. It consists of a differential pressure device and a fast exhaust valve that can achieve automatic control, instantly converting the air pressure energy into an air jet for direct blowing, thereby dispersing or vibrating objects. It is an ideal equipment for cleaning, non-polluting, and low-energy-consuming material conveying and blockage removal. The amplitude and vibration frequency of the vibrator 2 gradually change according to a certain law, fully meeting the requirements of large amplitude and low frequency at the feeding end and high frequency and small amplitude at the discharging end of the conveying operation. Therefore, as an excitation component, it forms a vibrating machine to achieve the conveying of materials.

[0041] In this embodiment, the vibrator 2 keeps running during discharging, and the air cannon 3 starts intermittently.

[0042] Specifically, the vibration amplitude of the air cannon 3 is greater than that of the vibrator 2. To avoid damage to the hopper 1 and the connection part of the materials in the hopper 1 caused by continuous large-amplitude vibration, the air cannon 3 is only started when the hopper 1 is blocked or intermittently.

[0043] In this embodiment, the vibrator 2 includes:

[0044] A housing 22, on which a motor 23 is arranged. Inside the housing 22, a vibrating rod 21 is arranged. One end of the vibrating rod 21 is connected to the cylinder body, the other end of the vibrating rod 21 is connected to the motor 23, and an eccentric block 25 and an eccentric adjustment block 24 are arranged on the vibrating rod 21.

[0045] Specifically, the vibrator 2 continuously provides small-amplitude vibration to reduce material adhesion.

[0046] In this embodiment, the output end of the air cannon 3 intermittently contacts the outer wall of the hopper 1, and the air cannon 3 is used to vibrate the hopper 1.

[0047] Specifically, the expansion air wave of the air cannon 3 directly impacts the outer wall of the hopper 1, causing the hopper 1 to vibrate and loosen the materials, avoiding directly blowing the materials and scattering them.

[0048] In this embodiment, a jet pipe is arranged at the output end of the air cannon 3, and the jet end of the jet pipe passes through the hopper 1 and is flush with the inner wall of the hopper 1.

[0049] Specifically, the compressed air provided by the air cannon 3 directly blows the blocked material, so that the material movement is no longer blocked by accumulation, which is direct and effective.

[0050] In this embodiment, the inner wall of the hopper 1 is provided with a groove opening downward, and the jet end of the jet pipe is arranged in the groove and faces the outlet end of the hopper 1 .

[0051] Specifically, the jet end is hidden by the groove to prevent the jet end from being worn and blocked.

[0052] In this embodiment, a drainage groove is provided at the open end of the groove.

[0053] Specifically, the airflow is guided through the drainage groove to prevent the material from being blown and scattered.

[0054] Furthermore, the drainage groove is directly connected to the discharge port.

[0055] In this embodiment, the groove is flush with the inner wall of the hopper 1 .

[0056] Specifically, it is to prevent the protrusion of the groove from intercepting and blocking materials.

[0057] In this embodiment, the detection mechanism 4 is arranged at the discharge end of the hopper 1, and includes:

[0058] The laser sensor has a transmitting end and a receiving end respectively arranged on both sides of the hopper 1, and is blocked and excited by the material when discharging.

[0059] Specifically, the discharging status is detected by a laser sensor, and if the discharging process is interrupted, material blockage occurs.

[0060] In this embodiment, the detection mechanism 4 is disposed on the batching scale 5 below the hopper 1 , and includes a reading module that is communicatively connected to the batching scale 5 , and the reading module is used to read the load-bearing data of the batching scale 5 .

[0061] Specifically, the reading module is connected to the display screen and the communication module. When the weight of the batching scale 5 no longer increases during the discharging process, material blockage occurs, and the air cannon 3 is controlled to start unblocking.

[0062] When a device for adding high-sulfur local ore in this embodiment is used, the specific process is as follows: the vibrator 2 is continuously started during the material discharge process. When the material is stuck and blocked, the detection mechanism 4 detects that the discharge end is no longer discharging material, and then the air cannon 3 is controlled to start, increase the vibration amplitude of the hopper 1 or directly blow the accumulated material, thereby loosening the material and discharging it. When the detection mechanism 4 detects that the material is discharging from the discharge end, the air cannon 3 is stopped.

[0063] The embodiments of the present utility model have been described above. The above description is exemplary and not exhaustive, and is also not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
