Technical Field

[0001] The utility model relates to an automatic stop device for full material in a bin, belonging to the technical field of material level monitoring. Background Art

[0002] During the electrolytic aluminum process, powdered materials need to be lifted to a bin by a small hopper through the rotation of a bucket elevator, and then conveyed from the bin to the use process. Since most bins are at high altitudes, it is impossible to timely and accurately judge the material level in the bin. If the materials in the bin are not consumed in time, it will cause the materials in the bin to overflow, affecting the surrounding environment. Even after the bin is full, the materials will accumulate and cause blockage, resulting in damage to related equipment. Content of the Utility Model

The upper rotating wing is used to monitor whether the bin is in a full state, and the lower rotating wing is used to monitor whether the bin is in an empty state.

[0005] The technical solution of the utility model is to provide an automatic stop device for full material in a bin. Under normal circumstances, the upper rotating wing and the lower rotating wing are driven by a driving motor to rotate. When the materials bury the rotating wings, the rotating wings stop rotating and send out a signal to control the start and stop of the bucket elevator.

[0006] Preferably, the material level monitoring device includes a driving motor and a rotating shaft. The rotating shaft is of a hollow structure, and the upper rotating wing and the lower rotating wing are sleeved on the rotating shaft.

A groove is opened on the inner wall of the rotating body, and a pressing block is movably arranged in the groove. The rotating body contacts the rotating shaft through the pressing block.

[0008] Further, the front end of the pressing block is in an arc shape. One end of a spring is connected to the rear end of the pressing block, and the other end of the spring is fixedly connected to the rotating body; the pressing block is in contact with and pressed against the rotating shaft by the thrust of the spring. When the rotating shaft rotates, the rotating body is driven to rotate through friction.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with specific embodiments.

[0022] 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.

[0023] 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.

[0024] like Figures 1 to 7 As shown, this embodiment is implemented by the following technical scheme: it includes a bucket elevator 2, the lower feed port of the bucket elevator 2 is connected to the feeding device 3, the upper discharge port of the bucket elevator 2 is connected to the silo 4 through a pipeline, and a material level monitoring device 1 is installed in the silo 4, which can monitor the material height in the silo and control the start and stop of the bucket elevator 2; the material level monitoring device 1 is provided with an upper rotating wing 12 and a lower rotating wing 14, the upper rotating wing 12 and the lower rotating wing 14 can be driven to rotate by a driving motor 11, the upper rotating wing 12 is used to monitor whether the silo is in a full silo state, and the lower rotating wing 14 is used to monitor whether the silo is in an empty silo state.

[0025] In this embodiment, the material level monitoring device 1 includes a driving motor 11 and a rotating shaft 13. The rotating shaft 13 is a hollow structure, and the upper rotating wing 12 and the lower rotating wing 14 are sleeved on the rotating shaft 13. The upper rotating wing 12 and the lower rotating wing 14 are both provided with a rotating body 122, and the rotating body 122 is symmetrically provided with wings 121 on both sides. The inner wall of the rotating body 122 is provided with a groove 126, and a pressing block 124 is movably arranged in the groove 126. The rotating body 122 contacts the rotating shaft 13 through the pressing block 124; the front end of the pressing block 124 is an arc surface, and the rear end of the pressing block 124 is connected to one end of the spring 123, and the other end of the spring 123 is fixedly connected to the rotating body 122; the pressing block 124 is pressed and pressed against the rotating shaft 13 by the thrust of the spring 123, and when the rotating shaft 13 rotates, the rotating body 122 is driven to rotate by friction. A proximity switch 131 is installed on the rotating shaft 13 at the position corresponding to the upper rotating wing 12 and the lower rotating wing 14. The proximity switch 131 is interlocked with the control system of the bucket elevator 2 and is used to monitor the movement state of the pressing block 124. A sleeve 132 connected to the drive motor 11 is also provided on the upper part of the rotating shaft 13. The sleeve 132 is provided with a threaded hole for screwing in a bolt to support the drive motor shaft. A sealing gasket 125 is also provided on the upper and lower sides of the rotating body 122. The sealing gasket 125 and the rotating body 122 together surround a closed cavity to prevent powdery materials from entering the cavity to interfere with monitoring.

[0026] The working process of the present utility model is as follows: When the material in the silo 4 is less and the rotating wings are not buried, the driving motor 11 drives the upper rotating wing 12 and the lower rotating wing 14 to rotate together, and the relative positions of the rotating shaft 13 and the pressing block 124 remain unchanged. At this time, if the proximity switch 131 is facing the pressing block 124, it continuously outputs a normally open signal; if the proximity switch 131 is not facing the pressing block 124, it continuously outputs a normally closed signal. When the material in the silo 4 buries the rotating wings, the buried rotating wings no longer rotate with the rotating shaft 13. At this time, the proximity switch 131 emits intermittent signals.

[0027] When the upper rotating wing 12 is buried by the material, the upper rotating wing 12 stops rotating, and the proximity switch corresponding to the upper rotating wing 12 emits intermittent signals, and the bucket elevator 2 stops feeding materials into the silo.

[0028] When the material in the silo is continuously consumed and the lower rotating wing 14 is exposed, the lower rotating wing 14 starts to rotate with the rotating shaft 13 together, and the proximity switch corresponding to the lower rotating wing 14 emits a continuous normally open or normally closed signal, and the bucket elevator 2 starts to feed materials into the silo.

[0029] Of course, the above content is only the preferred embodiment of the present utility model and cannot be considered as limiting the scope of the embodiments of the present utility model. The present utility model is not limited to the above examples either. Equivalent changes and improvements made by those of ordinary skill in the art within the essence of the present utility model shall fall within the scope covered by the patent of the present utility model.
