AI Technical Summary
During the unloading process of alumina powder, manual operation causes the tank truck to be often overpressed, which poses safety hazards and may cause the tank body to deform or burst, affecting production safety and personnel health.
Design an alumina powder tanker unloading ultra -pressure automatic alarm system. By setting up pressure sensors and sound light alarm on the pressure pipeline, the unloading pressure is realized in real time, and the alarm is automatically triggered when the pressure exceeds 0.3MPa. The pipeline's aerodynamic butterfly valve status reduces the pressure of tankers.
Effectively avoid the problem of over -pressure operations caused by improper manual operation, significantly reduce the risk of safety accidents such as tank explosion and dust explosion, ensure the safety production of the material supply workshop, and improve the efficiency of unloading.

Abstract
Description
Technical Field
[0001] The utility model relates to an automatic alarm system for overpressure in unloading of an alumina powder tank truck, belonging to the technical field of electrolytic aluminum production. Background Art
[0002] Unloading alumina powder tank trucks is a vital routine work in the feeding workshop. As a key raw material in industrial production, the stability and safety of alumina powder unloading process are directly related to the normal operation of the production line and the safety of workers. In this process, the control of unloading pressure is particularly critical. According to industry standards and safety regulations, the unloading pressure of tank trucks must be strictly controlled below 0.3Mpa to ensure a smooth unloading process.
[0003] However, in actual operation, due to the limitations and unpredictability of manual unloading, tank trucks often operate at overpressure. When the unloading pressure exceeds the safety threshold, if it is not discovered in time and the corresponding adjustment measures are not taken, it may cause a series of serious safety hazards. Long-term overpressure may cause the tank structure to deform, or even cause the tank to burst in extreme cases. In addition, unloading alumina powder under overpressure may also cause dust to fly, posing a threat to the health of operators and increasing the risk of fire and explosion. Utility Model Content
[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide an automatic alarm system for overpressure during unloading of alumina powder tank trucks, so as to avoid overpressure operation of the tank trucks during unloading and ensure safe production.
[0005] The utility model discloses an automatic alarm system for overpressure in unloading of alumina powder tank trucks, comprising a high-pressure storage tank, which is connected to the alumina powder tank truck via a pressurized pipe, and the tank truck is connected to the silo via a discharge pipe. A pressure sensor is provided on the pressurized pipe, and the pressure sensor is electrically connected to a control cabinet, and an audible and visual alarm is provided on the control cabinet.
[0006] The unloading pressure is set at 0.30Mpa. If the pressure exceeds 0.3Mpa during the unloading process of the tank truck, the pressure sensor will feedback the signal to the control cabinet, and the sound and light alarm will sound an alarm to remind the on-site unloading personnel to adjust the pressure in time to avoid overpressure operation of the tank truck unloading and ensure safe production.
[0007] The utility model has at least two silos, and the tank truck is connected to at least two silos through different discharge pipes, and the discharge pipes are provided with pneumatic butterfly valves. When the pressure exceeds 0.3Mpa during the unloading process, the discharge pipes corresponding to other silos are opened, which can not only reduce the pressure of the tank truck, but also improve the unloading efficiency; the conventional way to reduce the pressure of the tank truck is to reduce or shut off the intake pressure, which will reduce the discharge efficiency.
[0008] The pressurized pipe described in the utility model is also provided with a pneumatic butterfly valve. When the discharge pipes corresponding to all the silos are opened, the tank truck pressure cannot be effectively reduced. At this time, the pneumatic butterfly valve on the pressurized pipe is closed.
[0009] The outlet of the high-pressure storage tank of the utility model is provided with a pressure reducing valve.
[0010] The pressurized pipeline of the utility model is provided with a flow meter.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] Safety performance is significantly improved: by real-time monitoring of the unloading pressure and automatically triggering an alarm when overpressure occurs, the utility model effectively avoids overpressure operation problems caused by improper manual operation or negligence, and significantly reduces the risk of safety accidents such as tank bursting and dust explosion, thereby ensuring safe production in the feeding workshop.
[0013] Improved production efficiency: During the unloading process, when the pressure exceeds the set threshold, the system can automatically adjust the opening state of the pneumatic butterfly valve on the discharge pipe to balance the tank truck pressure and improve the unloading efficiency. This avoids the problem of reduced efficiency caused by reducing or shutting off the intake pressure to reduce the tank truck pressure in the traditional method. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described below in conjunction with specific embodiments.
[0017] However, the description of the present invention is merely an embodiment of structural and even functional description, and the scope of rights of the present invention is not limited by the embodiments described in the text.
[0018] For example, multiple embodiments may have multiple changes and multiple forms, and it should be understood that the scope of rights of the present utility model includes equivalents that can realize the technical idea.
[0019] like Figure 1As shown, this embodiment is implemented through the following technical scheme: it includes a high-pressure storage tank 1, the high-pressure storage tank 1 is connected to the alumina powder tank truck 6 through a pressurized pipe 5, the pressurized pipe 5 is provided with a flow meter, a pressure reducing valve 2, a pneumatic butterfly valve I 3, and a pressure sensor 4, the pneumatic butterfly valve I 3 and the pressure sensor 4 are electrically connected to a control cabinet 14, and the control cabinet 14 is provided with an audible and visual alarm 15.
[0020] The alumina powder tank truck 6 is connected to three silos, namely silo I11, silo II 12, and silo III 13, through three discharge pipes 7. The discharge pipes 7 corresponding to silo I11, silo II 12, and silo III 13 are respectively provided with pneumatic butterfly valve IV10, pneumatic butterfly valve III 9, and pneumatic butterfly valve II 8. The three pneumatic butterfly valves are also electrically connected to the control cabinet 14.
[0021] Initially, only silo I11 is unloaded. When the pressure exceeds 0.3Mpa during the unloading process, the pneumatic butterfly valves on the corresponding discharge pipes of other silos (silo II 12, silo III 13) are opened, which can not only reduce the tank truck pressure, but also increase the number of unloading silos and improve the unloading efficiency (the conventional way to reduce the tank truck pressure is to reduce or shut off the intake pressure, which will reduce the discharge efficiency). When the discharge pipes corresponding to all silos are opened, the tank truck pressure cannot be effectively reduced. At this time, the pneumatic butterfly valve I3 on the pressurized pipe 5 is closed, thereby completely cutting off the tank body intake, thereby ensuring the safe production of the feeding workshop.
[0022] Of course, the above contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the embodiments of the present invention. The present invention is not limited to the above examples, and any equivalent changes and improvements made by ordinary technicians in the technical field within the essential scope of the present invention shall fall within the scope of the patent coverage of the present invention.
