Description

Technical Field

[0001] The utility model relates to the field of rubber production equipment, in particular to a device for eliminating false signals of a material level meter of a carbon black storage bin. Background Art

[0002] As we all know, carbon black is a key raw material for enhancing the plasticity of tires during the production of rubber. It is used in large quantities during the production process, and requires large-capacity sealed containers for storage. At the same time, in order to meet the continuity of rubber production, the material level reserve position of the storage bin changes, and the requirements for the measurement accuracy of the silo level meter are gradually increasing. At present, the spiral damping level meter is the most widely used in actual production. Advantages: low price and high sensitivity. However, during use, there are faults such as misjudgment of the level meter signal and burnout of the level meter rotating motor. Due to the characteristics of the installation position of the level meter, the silo structure, and the slope of the silo wall, the accumulation of carbon black materials caused by repeated accumulation cannot be eliminated. After compacting the base of the level meter, the level meter cannot be rotated and damaged. The signal fed back by the level meter is untrue and inaccurate, resulting in a shortened service life of the level meter, affecting the efficiency of carbon black transportation, and increasing maintenance costs. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a device for eliminating false signals of a level meter in a carbon black storage bin, which solves the problem of false signals of the level meter, while increasing the service life of the level meter and reducing repair and maintenance costs.

[0004] The utility model adopts the following technical scheme to solve the technical problems: a device for eliminating false signals of a material level meter in a carbon black storage bin, which is provided with a carbon black storage bin, the bottom of which is connected to a material using device via a bin valve, and is characterized in that the lower part of the carbon black storage bin is a conical cylinder structure, a cylindrical material level meter mounting base is fixed on the side wall of the conical cylinder structure, a damping material level meter is inserted in the material level meter mounting base, the rear part of the damping material level meter is a sealing flange, the sealing flange is sealed and connected to the rear end of the material level meter mounting base via flange fixing bolts, a rotating induction plate of the material level meter is located in the middle of the damping material level meter, a material level meter cylinder with a conical inner cavity is installed on the inner side of the sealing flange with the rotating induction plate of the material level meter as the center, and the cone top of the inner cavity of the material level meter cylinder is located at the outer side of the material level meter mounting base.

[0005] The beneficial effects of the utility model are that the fluidity of the material on the base of the material level meter is increased, the problem of false signal of the material level meter is solved, the service life of the material level meter is extended, and the repair and maintenance cost is reduced.

DETAILED DESCRIPTION

[0010] In the figure, the utility model is provided with a carbon black storage bin 1, the bottom of the carbon black storage bin 1 is connected to the material device 6 via a bin valve 5, the lower part of the carbon black storage bin 1 is a conical cylinder structure, a cylindrical material level meter mounting base 7 is fixed on the side wall of the conical cylinder structure, a damping material level meter 4 is inserted in the material level meter mounting base 7, the rear part of the damping material level meter 4 is a sealing flange 10, the sealing flange 10 is sealed and connected to the rear end of the material level meter mounting base 7 via flange fixing bolts 9, the middle position of the damping material level meter 4 is a material level meter rotating induction plate 3, and a material level meter cylinder 8 with a conical inner cavity is installed on the inner side of the sealing flange 10 with the material level meter rotating induction plate 3 as the center.

[0011] The carbon black storage bin 1 is filled with carbon black 2. When the material level in the carbon black storage bin 1 is higher than the level meter rotating induction plate 3 on the damping level meter 4, the level meter rotating induction plate 3 stops rotating and triggers the level meter to send a level signal, thereby achieving the purpose of identifying the material level in the bin. Due to the installation method of the level meter, there is a phenomenon of accumulated carbon black on the connecting pipeline of the level mounting base 7. The level meter cylinder 8 is connected to the carbon black storage bin 1 through a sealing flange 10 and a flange fixing bolt 9. The cone top of the inner cavity of the level meter cylinder 8 is located outside the level meter mounting base 7. The accumulation space of carbon black is changed by the taper of the inner cavity of the level meter cylinder 8, so that carbon black 2 cannot accumulate to achieve the purpose of normal and accurate operation of the level meter.
