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:
The present invention relates to a kind of alumina producing and the connection structure is installed with the radar levelmeter of the liquid storage groove that scabs.
Background technology:
In aluminum oxide production process, medium that is circulated such as ore pulp, sodium aluminate solution, red mud, wash mud etc., these media are easy to scab in their storage tank of storage, thereby in the storage tank of the liquid that scabs whipping device are arranged all generally.In the prior art, use radar levelmeter the measurements liquid level of liquid that scabs, so that instruct the workman to operate, assurance production normal operation.(general the removing with the way of beaing of processing unit scabbed).The installation of radar levelmeter on storage tank connects structure as shown in Figure 1, and radar levelmeter (1) is fixed on the flange (3) by screw (5), nut (6), packing ring (7), and its bottom is goed deep into being not less than 10mm under the storage tank top board by pipe connecting (2).Whipping device can be stained with the liquid that scabs the bottom of radar levelmeter (1), scab in bottom at radar levelmeter (1), and knot is thick more more, can not beat, also can't clean, the precision of its radar levelmeter will be worse and worse along with duration of service, and until transmitting at last and received signal, work-ing life is less than promptly scrapping half a year.
Summary of the invention:
The technical problem to be solved in the present invention is: a kind of new radar material level meter connecting structure is provided, and this structure can overcome the deficiency that scabs in radar levelmeter bottom that prior art exists, measures reliable.
The technical solution used in the present invention is: with pipe connecting (2) lengthening, and be made as tapered tube, radar levelmeter (1) bottom is away from liquid level, and the liquid that scabs can not be stained with the bottom of radar levelmeter (1).
The present invention constitutes like this: it comprises pipe connecting (2), radar levelmeter (1) is connected with flange (3) by screw (5), nut (6), packing ring (7), pad (4) is arranged in the middle of it, the upper and lower end of pipe connecting (2) is connected with flange (3), storage tank top board (11) respectively, pipe connecting (2) is up-small and down-big tapered tube, its length is not less than 600mm, and its lower end diameter at butt end is not less than φ 450mm.
The upper end of pipe connecting (2) is connected with flange (3) by short tube (8).
The lower end of pipe connecting (2) is connected with storage tank top board (11) by short tube (9).
The length of short tube (8), short tube (9) is generally 100mm.
In the bottom of pipe connecting (2) air purge pipe (10) is arranged, to solve the problem that scabs that causes owing to the liquid evaporation that scabs.
By above structure, the mounting height of radar levelmeter is improved more than the 800mm, according to the emission angle calculating of ripple, on storage tank top board (11), open a bigger hole, be connected with the big end of pipe connecting (2).
The present invention can be used for pulp tank, reactive tank, red mud setting tank, laterite washing groove etc.
Compared with prior art, the present invention can make the liquid that scabs not be stained with the bottom of radar levelmeter (1), measures reliably, and effective, long service life reduces servicing time and labour intensity, saves production cost.
Description of drawings:
Fig. 1 is the synoptic diagram of prior art;
Fig. 2 is a synoptic diagram of the present invention.
Embodiment:
Embodiments of the invention: calculate perforate on storage scabs the storage tank top board 11 of liquid according to radar levelmeter 1 emission angle, and the short tube 9 of weld length 100mm, short tube 8 with level meter flange connecting 3 also weld length 100mm, between two short tubes, the pipe connecting 2 of length a 600～800mm of welding, pipe connecting 2 is a tapered tube, its upper end top diameter is φ 159mm, the lower end diameter at butt end is φ 450mm, at the bottom of pipe connecting 2 a welding air purge pipe 10 (position is below the bottom of radar levelmeter 1), radar levelmeter 1 is passed through screw 5, nut 6, packing ring 7 is connected with flange 3, and pad 4 is installed in the middle of it, and all the other are same as the prior art.
