The partition plate is attached to the side wall of the body. The sealing assembly is arranged on the buffer plate in a covering manner; one end of the sealing assembly is connected with the connecting arm; the other end of the sealing assembly is connected with the body; according to the utility model, the body can be protected through the buffer plate, abrasion during installation is reduced, and molten glass can be prevented from flowing into a crack between the body and the inner wall of the furnace body through the sealing assembly, so that the flowing path and speed of the molten glass are avoided, and the homogenization and clarification effects of the molten glass are improved.

The application discloses a method for homogenizing fermentation and producing aroma of cigar tobacco leaves and application thereof, and the method comprises the following steps: S1. After airing, the cigar tobacco leaves are initially humidified, and an apple acid solution with a pH value of 7-7.5 is sprayed on the initially humidified cigar tobacco leaves, and the humidified tobacco leaves are balanced to obtain humidified tobacco leaves; S2. The humidified tobacco leaves are wrapped with gauze, and then fermented to obtain aroma-producing cigar tobacco leaves. Through the addition of the apple acid, the humidification and fermentation of the cigar tobacco leaves are realized, the aroma content of the fermented cigar tobacco leaves is improved, the homogenization degree of the color and aroma content of the fermented tobacco leaves is improved, and the amount of carotenoid conversion products, cembrane degradation products, phenylalanine conversion products and bomeol aroma substances is extremely obviously improved.

This invention relates to waste soil treatment equipment, specifically disclosing an apparatus for preparing bentonite slurry using waste soil. The apparatus includes a crushing module (1) for receiving shield tunneling waste soil, a stirring module (2) connected to the crushing module (1), a conveying module (6) located at one end of the stirring module (2), and a mixing and storage module (3) located at the discharge end of the conveying module (6). The mixing and storage module (3) includes a mixing and storage container (301) and a stirring device (302). A slide rail is provided on the mixing and storage container (301), and the stirring device (302) is connected to the slide rail and adapted to move horizontally along the mixing and storage container (301). This apparatus for preparing bentonite slurry using waste soil refines the shield tunneling waste soil to a particle size consistent with that of bentonite used for synchronous grouting, replacing bentonite in mortar preparation. This not only enables the reuse of shield tunneling waste soil and reduces the amount of waste soil transported, but also reduces the procurement of raw materials, improves construction efficiency, and lowers project costs.

This invention relates to the field of platinum feed channels, specifically to a variable cross-section homogenization and purification device for platinum feed channels used in glass float glass production. The device includes a feed channel body composed of a contraction section, a homogenization section, and a flaring section. The contraction section is located on one side of the feed channel body at the inlet end. The contraction section has a funnel-shaped structure, with the larger opening end located at the feed end of the feed channel body. The diameter ratio of the two openings of the contraction section is 4:3, and the length ratio of the contraction section to the diameter of the smaller opening end is 3.5:3. The homogenization section has a cylindrical structure, with one end connected to the smaller opening end of the contraction section. The flaring section is located at the end of the homogenization section furthest from the contraction section. The flaring section also has a funnel-shaped structure, with the smaller opening end connected to the end of the homogenization section. This invention can suppress glass melt backflow, simplify the process flow, reduce production energy consumption, improve homogenization efficiency, and reduce the defect rate.
