4results about How to "Increase effective volume" patented technology

This utility model discloses a sealed food storage container, including a container body, a lid that fits with the container body, and a flexible sealing ring. The lid is a downward-opening cover structure. An annular groove with the opening facing downwards is provided around the outer edge of the container body's opening. The upper part of the sealing ring is embedded in the annular groove, while the lower part of the sealing ring protrudes outside the annular groove, sealing with the inner wall of the lid when the lid is placed on the container body's opening. This sealed food storage container achieves a seal while preventing the sealing ring from contacting the food inside the container, thus effectively preventing food stains from remaining on the sealing ring and preventing contamination of the food inside the container. Therefore, frequent disassembly and cleaning of the sealing ring is unnecessary, reducing the user's maintenance burden. Furthermore, since the edge of the lid and the sealing ring are not located within the internal space of the container body, the container body can achieve a larger effective volume with the same external dimensions, fully accommodating food and improving its internal space utilization.

This invention discloses a method for rapidly adjusting the furnace conditions of a lean-burn electric arc furnace, belonging to the field of pyrometallurgical nickel smelting technology. The method includes: measuring the height of the frozen layer inside the lean-burn electric arc furnace; when the frozen layer height is greater than 650 mm, simultaneously implementing coordinated control operations to reduce the slag oxidation depth (making the converter slag magnetic iron content <25%) and increase the reducing agent addition rate of the lean-burn electric arc furnace; after adjustment, measuring again, if the frozen layer height is less than 600 mm, restoring to normal process parameters; otherwise, repeating the adjustment until the target is met. This invention establishes a rapid response and upstream-downstream coordination mechanism based on the frozen layer as a criterion, which can effectively reduce the magnetic iron content in the slag, quickly eliminate excessively thick frozen layers, significantly improve slag fluidity, and ensure the stable and efficient operation of the lean-burn electric arc furnace system.

A dehumidifier, which comprises a casing, a refrigeration system and a water tank; the casing is internally provided with a containing space, the top surface of the casing is downwardly extended to be provided with a receiving cavity, the receiving cavity is arranged above the containing space, the refrigeration system is arranged in the containing space, and the refrigeration system comprises a compressor, a condenser and an evaporator; the water tank is upwardly and downwardly arranged in the receiving cavity; the water tank comprises a tank body, a handle and a handle, the inside of the tank body is provided with a water storage cavity; a tank cover is arranged on the top surface of the tank body and covers the top of the water storage cavity; the handle is arranged on the tank cover; a gap area is arranged on the tank cover, and the handle is upwardly and downwardly arranged in the gap area; the upper end of the handle is exposed on the top surface of the tank cover, and the lower end of the handle is arranged in the water storage cavity. The water tank is upwardly and downwardly arranged in the receiving cavity of the casing, so that the problem that the user needs to squat to take the water tank in the related dehumidifier can be solved. The handle of the water tank can be upwardly and downwardly lifted, so that the overall occupied space of the dehumidifier is reduced.

This invention discloses a control ball valve and a fertilization device, comprising: a valve body having a valve core cavity inside, the valve body having an inlet, a first outlet, and at least one second outlet communicating with the valve core cavity; a valve core rotatably mounted within the valve core cavity; the valve core including a hemispherical shell and a side stop arm, the hemispherical shell having a water passage hole corresponding to the first outlet, and the side stop arm connected to the side of the hemispherical shell away from the water passage hole; by rotating the valve core, the overlap between the side stop arm and the second outlet can be adjusted to control the opening degree of the second outlet. Compared with existing ball core structures, this solution's valve core, while ensuring normal adjustment function, achieves material reduction through degumming, reducing valve core material consumption and lowering costs, while simultaneously increasing the effective volume within the valve core cavity and enhancing the pressure-holding effect.
