Description

Technical Field

[0001] This utility model relates to the technical field of catalyst feeding devices, and in particular to a semi-open catalyst feeding tank. Background Technology

[0002] Catalysts are crucial for accelerating chemical reaction rates in industries such as chemical engineering, fine chemicals, food, and pharmaceuticals. During production, catalysts need to be added from the storage area to the reaction zone to ensure the smooth progress of the reaction. Adding catalysts from the storage area to the reaction zone requires a catalyst feeding tank. Several different catalyst feeding tank technologies exist, including a catalyst feeding tank for polyurethane prepolymer production with a pressure detection component, a catalyst feeding device that uses a rotating ball scoop to add catalyst, and a premixed catalyst feeding tank. However, these catalyst feeding tanks have complex structures, high manufacturing and maintenance costs, large footprint, and lead to catalyst waste. A semi-open catalyst feeding tank effectively controls maintenance costs and catalyst waste, while also having a simple structure and low manufacturing cost.

[0003] However, these catalyst feeding tanks have the following problems:

[0004] It has a complex structure and high manufacturing and maintenance costs.

[0005] With only a small catalyst inlet, the efficiency of catalyst loading is not high.

One side of the rotating cover plate 92 is rotatably connected to one side of the fixed cover plate 91 through a hinge 93. When the rotating cover plate 92 is lowered, it is used to close the second half position of the opening.

[0037] like Figure 1 and 2 As shown, a rubber strip seal 8 is provided at the upper end of the second half of the open section. When the rotating cover plate 92 is placed on the cylinder 2, it comes into sealing contact with the rubber strip 8.

[0038] like Figure 1 and 2 As shown, the semi-open catalyst feeding tank also includes three lifting lugs 1, which are installed on the upper side wall of the cylinder 2. The three lifting lugs 1 are evenly distributed around the axis of the cylinder 2.

[0040] like Figure 1 As shown, the semi-open catalyst feeding tank also includes a needle valve 4 for introducing nitrogen into the straight pipe 10. The needle valve 4 is installed on the side wall of the straight pipe 10. Nitrogen can be introduced into the straight pipe 10 and the cylinder 2 through the needle valve 4 to prevent oxidation of the catalyst in the cylinder 2 or to prevent oxidation of the catalyst discharged to the bag.

[0041] like Figure 1 and 4 As shown, the slide gate valve assembly 5 includes a slide gate 51.
