[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] This embodiment is adopted. The specific implementation is as follows:

[0029] like Figs. 1 to 3As shown, a material level limiter device for the top of an electrolytic aluminum silo is provided, in which a cavity 56 is opened on the top of the silo 5, and a mounting box 6 is installed above the cavity 56, and a contact sensor 61 is installed inside the mounting box 6. Since the stored electrolytic aluminum is in the form of dust, traditional laser sensors or level meters are prone to detection failure due to the influence of dust. Therefore, the contact sensor 61 is installed outside the silo 5 by means of the mounting box 6 to avoid failure.

[0030] It should be noted that, as the dust accumulates inside the silo 5, it will gradually rise. When it is stacked to a certain height, it will contact the bottom of the limit plate 93. Since the contact rod 94 is installed on the top of one side of the limit plate 93, the center of gravity will be offset. Therefore, in the offset state, the contact rod 94 will not contact the contact sensor 61. When the dust gradually pushes the limit plate 93 to be level, the contact rod 94 will pass through the cavity 56 and contact the contact sensor 61, thereby triggering an alarm.

[0031] like Figs. 1 to 3 As shown, in this embodiment, when the limit plate 93 is affected by dust accumulation, it will be displaced and rotated to a horizontal angle with the cooperation of the rotating shaft rod 92. At this time, the baffle 55 and the horizontal limit plate 93 will form a sealed space to prevent dust from floating into the installation box 6 and affecting the detection of the contact sensor 61.

[0032] In addition, there is an empty slot for material flow between the guide plate 54 and the baffle 55, which can also reduce the backflow effect caused by excessive dust accumulation to a certain extent.

[0033] like Figs. 1 to 3 As shown, in this embodiment, the bottom of the mounting bracket 4 is plugged into the socket 33 and there is a gap between the mounting bracket 4 and the connecting tube 3, so when vibration occurs, the mounting bracket 4 will resonate with the silo 5, thereby loosening the dust and facilitating the discharge of the material.

[0034] It should be noted that when the contact sensor 61 contacts the contact rod 94, an electrical signal is generated to the controller 8. At the same time, the controller 8 controls the operation of the electromagnetic unloading valve tube 52 and the vibration motor 7, so that the dust is discharged from the silo 5 in time, thereby effectively avoiding the problem of the hopper being damaged by the material in the silo and the lifting hopper 2 stopping, ensuring that the sealing material in the electrolysis workshop meets the requirements and improving work efficiency.

[0035] Working principle: the physical monitoring mode of the contact rod 94 and the contact sensor 61 replaces the laser material level detection means, which can avoid the problem that the dust affects the accuracy of the laser material level detection, the contact rod 94 is not in contact with the contact sensor 61 when the silo 5 does not reach the upper limit capacity, and the contact rod 94 is in contact with the contact sensor 61 in the process of gradually filling with dust, and the electromagnetic discharge valve pipe 52 and the vibration motor 7 responsible for discharging work to discharge the dust, effectively avoiding the problem of silo 5 and equipment top injury.

[0036] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
