Observation cover plate for titanium ore mixing tank and manufacturing method thereof

Abstract

The invention relates to an observation cover plate for a titanium ore mixing tank and a manufacturing method thereof. The observation cover plate comprises a gear box; sealing columns are verticallysymmetrically arranged at the top of the outer end face of the gear box, the outer end face of the gear box is assembled and connected with the front gear box, a mounting hole is formed at the centerof the front cover, side plates are symmetrically arranged on both sides of the front cover, a lateral plate is assembled and connected with the gear box, the outer wall of the front cover is providedwith an annular recessed mounting groove, sealing members are symmetrically arranged at the top of the inner part of the mounting groove, a third fitting hole is formed in the sealing member, both ends of the third fitting hole are of an open structure, an insulating pad is fixed on the inner wall of the third fitting hole, the sealing column penetrates the third fitting hole, and the sealing column is closely connected with the insulating pad. The observation cover plate for a titanium ore mixing tank and the manufacturing method thereof can ensure the sealing property and low-temperature resistance of the unit on the premise of reducing the weight of the tank.

Description

technical field [0001] The invention relates to an observation cover plate for a titanium ore mixing tank and a manufacturing method thereof, belonging to the technical field of titanium dioxide production. Background technique [0002] Titanium concentrate is extracted from ilmenite or titanomagnetite, and is the raw material for the production of titanium dioxide, which is widely used in various structural surface coatings, paper coatings and fillers, plastics and elastomers, and other uses Also includes ceramics, glass, catalysts, coated fabrics, printing inks, roofing granules and fluxes. [0003] In the production of titanium dioxide, it is necessary to pretreat and mix the ground titanium concentrate and concentrated sulfuric acid to obtain the titanium liquid required for the subsequent process; the mixing needs to be completed in the mixing tank (premixing tank), and the existing mixing tank such as figure 1 As shown, an inspection pipe is installed on the top surf...

AI Technical Summary

Problems solved by technology

[0004] When the above-mentioned existing mixing tank is opened, the inspection cover needs to be turned away manually, so that the inspection cover is separated from the inspection pipe, and the workers can observe the mixing status in the mixing tank through the inspection pipe, and the inspection pipe can also be lowered into the mixing tank to carry out For maintenance and slag removal, when closing, turn the inspection cover to the inspection pipe, screw on the bolts to complete the limit; the inspection cover is very heavy, and at least two workers are required to open it when it is turned, and the observation of the mixing tank is more frequent, and the lower The maintenance of the tank needs to be carried out every few months. Therefore, it is very time-consuming and laborious for the workers to complete the above-mentioned observation operations, which wastes human resources and affects the observation efficiency. Long-term opening and closing transportation also easily affects the sealing of the inspection panel.
