In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The embodiments of the utility model provide a belt conveyor device and an alumina conveying system, which facilitate the rapid loading of materials such as alumina into a transport vehicle, and are convenient for technicians to find problems and prevent the conveyor belt from affecting the transportation of materials.

[0032] Combine the following Figure 1-Figure 4 The technical solution provided by the utility model is described in more detail.

[0033] like Figure 1-Figure 4 As shown, the belt conveyor device provided by the utility model includes a tank body 2, a frame and a conveyor belt 3, wherein: the frame supports the conveyor belt 3, the conveyor belt 3 is transmitted on the frame, the conveyor belt 3 is inclined compared to the horizontal plane, and its high end is located above the tank body 2, and the conveyor belt 3 is used to transport materials from a low place to the tank body 2; a filling port 21 is provided below the tank body 2, and the filling port 21 is located above the ground. When the filling port 21 is opened, the material in the tank body 2 can flow into the transportation device through the filling port 21.

[0034] Arranged on both sides of the frame are: a deviation switch 91 for detecting whether the conveyor belt 3 deviates from the conveyor track, a tear detector 93 for detecting whether the conveyor belt 3 is torn, a speed detector 94 for detecting whether the conveyor belt 3 is stalled, and a control unit. The control unit is electrically connected to the deviation switch 91, the tear detector 93, the speed detector 94 and the conveyor belt 3, and is used to control the conveyor belt 3 to stop working when the conveyor belt 3 deviates from the conveyor track or is torn or stalled.

[0035] Among them, the deviation switch 91, the tear detector 93, and the speed detector 94 are all existing mature technologies and can be directly purchased from the market, and their structures are not described in detail here. Figure 4 As shown, the deviation switch 91, the tear detector 93, and the speed detector 94 are electrically connected to the conveying end of the control unit. The control unit can control the conveying belt 3 to stop working after starting according to the signals of the deviation switch 91, the tear detector 93, and the speed detector 94, so as to prevent the conveying belt 3 from running in a problem state for a long time. The control unit can be a single chip microcomputer with a pre-stored setting program, etc.

[0036] The belt conveyor provided by the utility model can convey materials such as alumina, and its purpose is to convey alumina and other materials into a tank body 2 with a certain height, and then open the filling port 21 to allow the materials in the tank body 2 to flow directly into the conveying vehicle to transport alumina without manual loading.

[0037] The inclined setting of the conveyor belt 3 can convey materials such as alumina from a raw material tank at a lower location to a tank body 2 with a certain height. By opening the filling port 21 of the tank body 2, the materials in the tank body 2 can be transported into the conveyor vehicle, which is convenient for quickly loading materials such as alumina into the transport vehicle; when the conveyor belt 3 deviates, tears or stalls, the control unit controls the conveyor belt 3 to stop working, which is convenient for the conveyor belt 3 to be shut down for maintenance, and for technicians to find problems, thereby preventing the conveyor belt 3 from affecting the transportation of materials.

[0038] As an alternative embodiment, see Figure 3 and Figure 4 As shown, a pull-rope switch 92 is provided on the side of the frame, and the pull-rope switch 92 is electrically connected to the conveyor belt 3 for stopping the conveyor belt 3 .

[0039] Among them, the pull rope switch 92 is an existing mature technology, which can be directly purchased on the market, and its structure is not described in detail here. The pull rope switch 92 is installed on the frames on both sides of the conveyor belt 3, and the pull rope switch 92 is connected along the two sides of the conveyor belt 3 with a wire rope. When an emergency occurs to the conveyor belt 3, the wire rope is pulled at any point along the site, and the wire rope drives the driving arm to rotate, and the torsion spring is driven by the transmission shaft to displace the precision cam, driving the micro switch to cut off the control line, so that the conveyor belt 3 stops running.

[0040] As an alternative embodiment, see Figure 3 As shown, a material blockage detector 93 is provided on the pipeline between the conveyor belt 3 and the tank body 2, and the control unit is electrically connected to the material blockage detector 93. The control unit is electrically connected to an alarm. The control unit is used to control the alarm to emit an alarm prompt when a material blockage is detected in the pipeline.

[0041] The working principle of the material blockage detector is based on the control principle of the flow of liquid, gas, powder and other materials. When the conveyor belt 3 operates normally, the material will flow through the material blockage detector on the pipeline. If the flow of the material reaches the preset standard and there is no obstruction, the material blockage detector will send a signal, and the converter will send a normal working signal after receiving the signal. If a blockage occurs in the equipment, the flow of the material will suddenly decrease or be interrupted, and the material blockage detector will sense the signal change. At this time, the converter will transmit the signal to the alarm and issue an alarm prompt. In this way, the detection and feedback of pipeline blockage are realized in a timely manner.

[0042] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the belt conveyor device also includes a connecting pipe 4, a chute 5 and a discharge pipe 6, wherein: the connecting pipe 4 connects the chute 5 and the high end of the conveying belt 3, the chute 5 extends along the arrangement direction of the tank body 2, all the discharge pipes 6 are connected to the chute 5, and the lower end of the discharge pipe 6 is connected to the corresponding tank body 2.

[0043] After the material reaches the upper end of the conveyor belt 3, it enters the connecting pipe 4 and the chute 5. The chute 5 is inclined compared to the horizontal plane. Under the action of gravity, the material can flow along the chute 5 from the discharge pipe 6 into the tank body 2, thereby realizing the transfer of the material from the conveyor belt 3 to the tank body 2.

[0044] As an alternative embodiment, see Figure 2 As shown, the belt conveyor device also includes an air duct 7 and a driving fan 8, wherein the driving fan 8 is connected to the air duct 7, and the air duct 7 is connected to the chute 5, and the material in the chute 5 can flow into the tank body 2 driven by the airflow.

[0045] The fan 8 is driven to operate, so that an airflow with a certain pressure is formed in the air duct 7, and the material in the slide pipe 5 flows into the tank body 2 under the action of gravity and the driving of the airflow, which further facilitates the unloading of the material.

[0046] As an optional implementation, participate Figure 1 As shown, the frame includes a reinforcing frame 11, and the reinforcing frames 11 are arranged at intervals along the moving direction of the conveyor belt 3. The above structure can improve the stability of the conveyor belt 3 structure.

[0047] This embodiment also provides an alumina conveying system, including the above-mentioned belt conveying device.

[0048] The belt conveyor device can be applied to the conveyance of alumina, thereby improving the working efficiency of the conveyance of alumina.
