Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbide furnaces and is a wear-resistant insulating combined weighing bucket. Background Art

[0002] At present, the continuous unloading method is generally adopted in the closed calcium carbide production process. In the raw material conveying system in the calcium carbide furnace field, the unloading hopper and the unloading pipe have a large daily loading volume, and long-term loading causes wear on the inner wall of the unloading hopper, which leads to a decrease in the insulation value of the unloading hopper, causing the unloading hopper and the unloading pipe to spark, thereby increasing the maintenance and replacement frequency; on the other hand, the existing unloading hopper does not have a weighing and metering function, so it is impossible to weigh the material in the insulating hopper. Summary of the invention

[0003] The utility model provides a wear-resistant insulating combined weighing hopper, which overcomes the deficiencies of the above-mentioned prior art and can effectively solve the problem of reduced insulation performance of the existing calcium carbide furnace unloading hopper due to wear and the problem of inability to weigh the material in the insulating hopper.

The weighing frame is provided on the outer side of the upper part of the insulating hopper, and the frame is fixedly installed on the lower side of the weighing frame. The weighing assembly includes a pressing ear and a weighing sensor. At least two weighing sensors are provided on the upper side of the weighing frame.
