Description

Technical Field

[0001] The utility model relates to the technical field of material level detection, in particular to a material level meter. Background Art

[0002] The principle of the original admittance level meter is to install a conductive metal rod on the upper part of the silo. When the material level rises to a certain height, it will touch the upper metal rod. The electronic circuit connected to this metal rod detects the admittance change and activates the output relay, allowing the device to send a signal.

[0003] However, this type of level meter is unreliable in an environment with highly conductive dust. Dust adheres to the surface of the insulator between the conductive rod and the metal frame to form a conductive film, which changes the conductance between the conductive rod and the grounding body, causing the level meter to malfunction and send out an erroneous arrival signal. Utility Model Content

[0004] The main purpose of the utility model is to provide a material level meter, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A material level meter comprises a silo, a cylindrical probe and an inclination sensor, wherein a lower hopper is arranged above the interior of the silo, materials are arranged at the inner bottom end of the silo, a fixed seat is arranged above one end of the silo at the lower end, a suspension cable is connected to the bottom of the fixed seat, a cylindrical probe is connected to the end of the suspension cable away from the fixed seat, an inclination sensor is arranged on the cylindrical probe, hanging rings are fixed to both ends of the outer wall of the bottom of the lower hopper, connecting chains are connected to the hanging rings, a vibrating rod is arranged below the lower hopper, a plurality of tilting rods are fixed to the outer wall of the vibrating rod, and a plurality of vertical rods are fixed at equal distances below the tilting rod.

[0007] Preferably, the suspension cable, cylindrical probe and inclination sensor are all in a naturally vertical state.

[0008] Preferably, the lower hopper is located just above the middle of the silo.

[0009] Preferably, the connection point between the cylindrical probe and the suspension cable is located below the horizontal line of the lower hopper discharge port.

[0010] Preferably, one end of the connecting chain away from the hanging ring is respectively connected to the top of the vibrating rod.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The material is discharged from the hopper into the silo, and the material gradually accumulates and the material level rises in the silo. The cylindrical probe originally suspended in the silo by the fixed seat and the suspension cable will gradually change from a vertical state to an inclined state due to the excessive accumulation of materials. The inclination sensor provided on the cylindrical probe will actuate the output relay contact after detecting the inclination, and send out an in-position signal, so that the staff can stop the material discharge work, so that the device not only has the effect of simple and easy material level detection, but also has the advantages of safety, reliability and low cost. Even if the material hits or touches when it does not reach the required material level, it can be judged whether the required material level is really reached through the inclination time detected by the inclination sensor, avoiding the situation where the judgment of the staff is affected by the accidental touch;

[0013] When the material is being unloaded, the vibrating rod starts to work and generates vibration, which will be transmitted to the inclined rod and the vertical rod, so that the material can collapse around the center point through vibration, avoiding the situation where the material is unloaded in a cone shape and causing excessive deviation in the detected material level.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-2 As shown, a material level meter comprises a silo 1, a cylindrical probe 6 and an inclination sensor 7. A lower hopper 2 is arranged above the interior of the silo 1, and a material 3 is arranged at the bottom end of the interior of the silo 1. A fixed seat 4 is arranged above one end of the lower hopper 2 in the silo 1, a suspension cable 5 is connected to the bottom of the fixed seat 4, and a cylindrical probe 6 is connected to the end of the suspension cable 5 away from the fixed seat 4. The inclination sensor 7 is arranged on the cylindrical probe 6, and hanging rings 8 are fixed at both ends of the outer wall of the bottom of the lower hopper 2, and connecting chains 9 are connected to the hanging rings 8. A vibrating rod 10 is arranged below the lower hopper 2, and a plurality of tilting rods 11 are fixed to the outer wall of the vibrating rod 10, and a plurality of vertical rods 12 are fixed at equal distances below the tilting rod 11.

[0019] In this embodiment, the suspension cable 5, the cylindrical probe 6 and the inclination sensor 7 are all in a naturally vertical state.

[0020] In this embodiment, the lower hopper 2 is located directly above the middle of the silo 1 to avoid accumulation on one side.

[0021] In this embodiment, the connection point between the cylindrical probe 6 and the suspension cable 5 is located below the horizontal line of the discharge port of the lower hopper 2, so that the inclination sensor 7 can accurately detect the collapsed material level.

[0022] In this embodiment, one end of the connecting chain 9 away from the hanging ring 8 is connected to the top of the vibration rod 10 respectively.

[0023] Working principle: material 3 is discharged from the hopper 2 into the silo 1. When the material 3 is gradually accumulated and the material level rises in the silo 1, the cylindrical probe 6 originally suspended in the silo 1 by the fixed seat 4 and the suspension cable 5 will gradually change from a vertical state to an inclined state due to the excessively accumulated material 3. The inclination sensor 7 provided on the cylindrical probe 6 will actuate the output relay contact after detecting the inclination, and send out an in-place signal, so that the staff can stop the material discharge work, so that the device not only has the effect of simple and easy material level detection, but also has the advantages of safety, reliability and low cost. Even if the material hits or touches when it does not reach the required material level, it can be judged whether the required material level is really reached by the inclination time detected by the inclination sensor 7, so as to avoid the situation where the judgment of the staff is affected by the accidental touch. When the material is discharged, the vibrating rod 10 starts to work and vibrates, and the vibration is transmitted to the inclined rod 11 and the vertical rod 12, so that the material 3 can collapse around the center point through vibration, so as to avoid the situation where the material is cone-shaped and the material level is detected and there is too much deviation.
