Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0020] Such as figure 1 As shown, the present invention includes a pump cover 1 , an installation bottom plate 5 located above the pump cover 1 , and a pump shaft 4 passing through the centers of the pump cover 1 and the installation bottom plate 5 . It also includes a support pipe 2 installed between the pump cover 1 and the installation bottom plate 5 and sleeved outside the pump shaft 4 . It also includes an annular throttling plate 3, the outer edge of which is fixed on the inner wall of the support pipe 2, and the gap between the inner edge and the pump shaft is 0.5-1mm. The annular cavity formed between the support tube 2 and the pump shaft 4 is divided into two upper and lower cavities by the annular throttle plate 3, and the upper part of the annular throttle plate 3 is a nitrogen isolation cavity 7. When in use, the nitrogen isolation cavity 7 N...

Abstract

The invention discloses an improved submerged pump for conveying titanium tetrachloride. The upper part of an annular throttling plate (3) in an annular cavity formed between a supporting pipe (2) and a pump shaft (4) is a nitrogen isolation cavity (7); a group of filler (20) is arranged on each of the upper side and the lower side in a filler box (11); an air division ring (19) is arranged near each group of filler; an isolated nitrogen channel is formed in the filler box (11) and provided with an isolated nitrogen inlet (14) and an isolated nitrogen outlet (15) communicated with the nitrogen isolation cavity (7); the filler box (11) is also provided with a cooling nitrogen channel with a cooling nitrogen inlet (18); and the inner end of the cooling nitrogen channel is communicated with the air division rings (19). The nitrogen isolation cavity prevents titanium tetrachloride steam from ascending, so that the filler at the upper end seals the nitrogen isolation cavity to form dual sealing; and therefore, the titanium tetrachloride liquid and the titanium tetrachloride steam can be effectively sealed.

Description

[0001] technical field [0002] The invention relates to a submerged pump for transporting titanium tetrachloride. Background technique [0003] Titanium tetrachloride is an important intermediate in the production of titanium metal and its compounds. It is a colorless liquid at room temperature. It fumes in the air to form titanium dioxide and hydrochloric acid droplets. It releases heat when heated or meets water, and emits toxic and corrosive fumes. , has strong corrosiveness, and is often used in the production of sponge titanium, titanium dioxide, etc., and can also be used as naval smoke bombs. [0004] When the existing submerged pump is used to transport titanium tetrachloride, the leakage of the medium is easy to occur. If a submerged magnetic pump is used, it is easy to cause damage to the magnetic pump when pumping occurs. Therefore, the market is in urgent need of a submerged pump with good gas tightness for transporting titanium tetrachloride. Contents of ...
