Radar material level meter connecting structure

Abstract

The invention discloses a connecting structure of a radar level detector of a scab liquid storage groove used for producing alumina. The radar level detector (1) is connected with a flange (3) through screws (5), nuts (6) and a washer (7), and the middle of the radar level detector (1) is provided with a shim (4); the upper and lower ends of a connecting pipe (2) are respectively connected with the flange (3) and a storage groove roof (11). The radar level detector is characterized in that: the connecting pipe (2) is a taper pipe which is small in the upper end and large in the lower end, the length of which is not less than 600mm and diameter of the large end of the lower end is larger than Phi 450mm; the upper end of the connecting pipe (2) is connected with the flange (3) through a short pipe (8); and the lower end of the connecting pipe (2) is connected with the storage groove roof (11) by a short pipe (9); an air blowing and sweeping pipe is arranged on the lower part of the connecting pipe (2). The invention is used for producing pulp troughs, reaction tanks, red mud settlement slots and red mud washing troughs used for manufacturing alumina.

Description

Technical field: [0001] The invention relates to a radar level gauge installation and connection structure of a scarred liquid storage tank for alumina production. Background technique: [0002] In the alumina production process, the circulating media such as ore pulp, sodium aluminate solution, red mud, washing mud, etc., these media are easily scarred in the storage tanks where they are stored, so the storage tanks for the scarred liquid are generally There are mixing equipment. In the prior art, a radar level gauge is used to measure the level of scarred liquid, so as to guide workers to perform operations and ensure normal operation of production. (Process equipment generally uses beating to remove scars). The installation and connection structure of the radar level gauge on the storage tank is as follows: figure 1 As shown, the radar level gauge (1) is fixed on the flange (3) by screws (5), nuts (6) and washers (7), and its bottom is penetrated by the connecting pipe (2) in...

AI Technical Summary

Problems solved by technology

The stirring equipment will stain the scarred liquid on the bottom of the radar level gauge (1), and the scarring on the bottom of the radar level gauge (1) will become thicker and thicker, which can neither be beaten nor cleaned. The accuracy of the meter will become worse and worse with the use of time, until finally it cannot transmit and receive signals, and it will be scrapped after less than half a year of service life
