In the construction of large-scale cement or asphalt concrete mixing plants, silos are generally used for storing materials in order to save storage land, facilitate loading and unloading mechanization and automation, reduce labor intensity, improve production efficiency, reduce material loss and pollution of dust to the environment. Silos are often built from reinforced cement concrete and are structurally sound and durable. In the actual construction production process, the materials stored in the silo fall down and are discharged by self weight, and the materials can be frequently arched to cause that the materials are not normally discharged from the discharge opening due to the influence of the water content and friction force on the inner wall of the silo, and particularly, the arching phenomenon is more frequent. The material arching can not be led out, so that the normal operation of the stirring station can be interrupted, the operation period is prolonged, the production efficiency of the stirring station is severely restricted, and even the stirring station can not be produced; meanwhile, uneven material feeding can be caused, the subsequent proportioning precision of the materials is directly affected, and the quality of concrete is reduced.

In order to ensure the normal operation of the stirring station and the batching precision, mechanical vibration arch breaking is often adopted in engineering to break the arch-forming phenomenon. The mechanical vibration arch breaking adopts the vibrator arranged on the bin wall, and the materials adhered on the bin wall are separated through vibration, so that the arch breaking purpose is achieved. The material granularity, shape and temperature are changed continuously, and the arching position is also changed continuously, so that the effect is not ideal; if a plurality of vibrators are arranged on the bin wall, the vibrators can vibrate simultaneously to provide omnibearing vibrating force for the bin to break the arch, but the vibration of the vibrators which are not in the arch-forming position can cause the increase of energy consumption.

However, the bin blockage removing device adopts a mode of combining a scraping plate and airflow impact to remove blockage, and has a complex structure; because the arch-forming position cannot be judged, in order to ensure that the blockage at any position on the inner surface of the silo can be cleaned, the movement range of the scraping plate covers the whole inner surface of the diameter-reducing section, when the silo contains materials, the movement of the scraping plate is difficult, great power is required to be provided for driving the scraping plate, and the applicability of the silo is poor. In addition, the scraper blade portion and the compressed gas portion are controlled to perform arch breaking operation when the flow interruption of the discharge opening is detected, and in the process, feeding of the bin is interrupted, so that production is affected.

In this embodiment, a plurality of sets of level switches 43 are arranged at intervals along the height direction of the bin 2, and each set of level switches 43 and the corresponding set of vibrators 41 are located in the same horizontal plane to monitor the empty height of the bin 2, and the empty height range indicates that no material exists. The level switch 43 is preferably a rotary-blocking level switch, type PFG86, which typically directly connects the clutch to the drive shaft after decelerating the motor, and rotates the shaft at a low rotational speed, with blades at the shaft end. When the material exceeds the blades, the blades are blocked from rotating, and rotary displacement is generated around the main shaft.

the empty height and the level height information are acquired by the controller 5 and compared with each other:

if the empty height is within the level range, that is, when the level gauge 42 displays that there is material at the empty height position and the level switch 43 at the empty height position does not detect a material signal, it indicates that there is material arching above the empty height position, and the controller 5 controls the vibration motor 412 located above and closest to the empty height position to be powered on to perform arch breaking operation, the material is vibrated to fall, and arch breaking is released. In this process, the temperature sensor 10 is also used to detect the temperature of the vibration rod 413, the controller 5 compares the temperature value detected by the temperature sensor 10 with the set upper limit value of the working temperature of the vibration rod 413, and controls the corresponding vibration starting motor 412 to stop working when the detected temperature value is greater than or equal to the set upper limit value of the working temperature of the vibration rod 413 so as to avoid overheating and burning out of the vibration rod 413; the vibration sensor 11 can also be used for detecting the vibration state of the corresponding vibration rod 413, if the controller 5 starts the vibration starting motor 412 corresponding to the vibration rod 413 to vibrate and then cannot receive the vibration signal transmitted by the vibration sensor 11 on the vibration rod 413, the vibrator 41 is in an abnormal working state, and the staff is reminded to overhaul in time; if the controller 5 starts the corresponding vibration starting motor 412 of the vibration rod 413 to vibrate and then receives the vibration signal transmitted by the vibration sensor 11 on the vibration rod 413, it indicates that the vibrator 41 is in a normal working state.

If the level switch 43 does not detect a no-material signal, the controller 5 controls the vibrator 41 not to be started, so that energy consumption is saved.

If the empty height is greater than the level height, it indicates that there is no material in the bin 2, and the controller 5 controls the vibrator 41 not to be started, so as to save energy consumption.

Therefore, the material arch breaking system 4 can perform vibration arch breaking aiming at the arch-forming position, the arch breaking effect is good, all vibrators 41 do not need to be started, the vibrators 41 are prevented from vibrating empty, and the energy consumption can be reduced. Meanwhile, the arch-breaking system 4 for the materials can be used for timely knowing the arch-forming position, the vibrator 41 can be started to break the arch without waiting for the material breaking of the discharge opening 23, and the material breaking of the discharge opening 23 is not needed, so that normal production and the like are ensured.

In addition, the material arch breaking system 4 in the embodiment adopts the packaging layout for each structural component, the hardware connection is reliably installed, the rain-proof and falling-proof measures, the electric shock protection device, the safety isolation fence and other safety measures can be arranged, and the material arch breaking system can be used for storing different materials in various different types of high-level storage bins and has the upgrading and expanding functions.

It should be understood that each set of level switches 43 may not be located in the same plane as the corresponding set of vibrators 41, for example, referring to fig. 4, in this embodiment, each set of level switches 43 may be disposed below the corresponding set of vibrators 41, preferably 20-50 cm below the corresponding set of vibrators 41, which can achieve the technical effects of the embodiment of the present utility model as well. A level switch 43 may be installed under each vibrator 41. When in use, the controller 5 can pertinently start one or more of the vibrators 41 in each group to break arches according to the detection condition of each material level switch 43, without starting the whole group of vibrators 41, thereby achieving the purpose of further reducing energy consumption. For example, if only a part of the level switches 43 detect the no-material signal and the rest of the level switches 43 detect the material-material signal in the set of level switches 43 corresponding to the empty height, the controller 5 only needs to control the vibrator 41 corresponding to the upper part of the level switches 43 detecting the no-material signal to vibrate.

It will be appreciated that the material arching system 4 may also include other components, such as contactors, protectors, sequence controllers, time relays, etc., which are part of the prior art and are not described in detail herein for brevity.
