Description

Technical Field

[0001] This utility model relates to a warning device for the feeding station of aluminum electrolytic covering material, belonging to the field of electrolytic aluminum production technology. Background Technology

[0002] Aluminum electrolysis covering material is usually transported to the covering material vibrating screen by a material cart, the material is poured onto the vibrating screen, and then flows from the vibrating screen into the chute below, until it is lifted into the covering material silo by a bucket elevator.

[0003] The vibrating screen is covered with a dust cover made of welded steel plates. During the reversing process, there is always a problem of inaccurate reversing of the material cart. Reversing by feeling and awareness poses uncertainties and safety factors such as easy collision with the vibrating screen guard plate, dust cover and wall. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an aluminum electrolysis covering material feeding station warning device to solve the above problems.

[0005] The aluminum electrolysis covering material feeding station warning device of this utility model includes a covering material feeding dust cover. The rear end of the covering material feeding dust cover is equipped with a diffuse reflection photoelectric switch and an indicator light. The diffuse reflection photoelectric switch and the indicator light are both connected to an intermediate relay. The diffuse reflection photoelectric switch, the indicator light and the intermediate relay are powered by a power supply.

[0006] Furthermore, the inner front end of the dust cover for feeding the covering material is equipped with an audible alarm, which is connected to an intermediate relay and a power supply.

[0007] Preferably, the traffic lights include red and green lights.

[0008] The intermediate relay and the power supply are located inside the electrical control box.

[0009] Furthermore, a parking limiter is provided at the bottom of the dust cover for feeding the covering material.

[0010] After installing the position warning device, the green light remains constantly on. When the material truck is reversing to load materials, the driver sees the red light turn on through the rearview mirror. Once the diffuse reflection photoelectric switch detects the vehicle's arrival, the green light turns off, indicating the unloading position. This makes the vehicle's arrival more intuitive and noticeable, avoiding the unsafe factors of reversing based on feeling or awareness. It also reduces the number of times the driver needs to get out and get in the vehicle to confirm reversing into position, reducing potential hazards such as collisions with the vibrating screen's guard plate, dust cover, and walls, and minimizing the need for the driver to get out of the vehicle to observe the site. In addition, a physical parking limiter is also installed to further ensure reversing safety.

[0011] The advantages of this utility model compared with the prior art are:

[0012] 1. Improved reversing accuracy: By installing diffuse reflection photoelectric switches and signal lights, drivers can judge whether the vehicle has reached the correct position by observing changes in the signal lights while reversing, thus improving reversing accuracy. This method is more intuitive and accurate compared to traditional reversing based on feeling and awareness.

[0013] 2. Improved safety: By adding an audible alarm and a parking limiter, this invention further improves the safety of reversing. When the vehicle reaches the correct position, the audible alarm will sound to remind the driver to stop; at the same time, the parking limiter will also act as a physical limiter to prevent the vehicle from reversing excessively and colliding with the dust cover or wall (an alarm will sound before reaching the parking limiter).

[0014] 3. Improved work efficiency: Since drivers can judge whether the vehicle has reached the correct position by observing the changes in traffic lights and hearing the alarm, the number of times drivers need to get in and out of the vehicle to confirm that the vehicle has been reversed into the parking space can be reduced, thereby improving work efficiency.

[0017] The present invention will be further described below with reference to specific embodiments.

[0018] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.

[0019] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.

[0020] like Figure 1 As shown, this embodiment is achieved through the following technical solution: It includes a material feeding dust cover 1, with a suction pipe 8 connected to the top of the material feeding dust cover 1. A diffuse reflection photoelectric switch 2 and an indicator light 3 are located at the rear end of the material feeding dust cover 1. Both the diffuse reflection photoelectric switch 2 and the indicator light 3 are connected to an intermediate relay 4. The diffuse reflection photoelectric switch 2, the indicator light 3, and the intermediate relay 4 are powered by a power supply 5. Additionally, an audible alarm 7 is located at the front end of the material feeding dust cover 1, and the audible alarm 7 is connected to the intermediate relay 4 and the power supply 5.

[0021] In this embodiment, the signal light 3 includes a red light and a green light, an intermediate relay 4, and a power supply 5 located in the electrical control box 6.

[0022] The bottom of the dust cover 1 for feeding the covering material in this embodiment is equipped with a parking limiter 9.

[0023] This utility model features a diffuse reflection photoelectric switch 2 installed on the steel plate at the rear of the material feeding dust cover 1. The power supply for the diffuse reflection photoelectric switch 2 is introduced from the electrical control box 6. A signal light 3 is installed in a prominent position in the driver's rearview mirror. The signal light 3 contains at least two colors: red and green. An intermediate relay 4 is installed inside the electrical control box 6. The diffuse reflection photoelectric switch 2 controls the operation of the intermediate relay 4, which in turn controls the red and green lights. Specifically, the normally open contact is connected to the red light, and the normally closed contact is connected to the green light. When the diffuse reflection photoelectric switch 2 senses that the vehicle has stopped, the normally open contact is energized, the red light illuminates, and the audible alarm 7 sounds. When it does not sense the vehicle, the green light illuminates. That is, when no material is being added or the vehicle has not reached the unloading position, the green light illuminates. When the vehicle reaches the unloading position, the diffuse reflection photoelectric switch 2 senses the vehicle, and the red light illuminates.

[0024] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
