Abstract
The utility model discloses a mounting structure of a nuclear radiation level sensing device on a pressurized container. The mounting structure comprises a container (1), a radiation source and lead protective tank (2), a probe (3), a radiation source hole (4) and a movable stop (5), wherein the radiation source and lead protective tank (2) and the probe (3) are corresponding arranged on a chord wire which is arranged on the circumference of the container (1). The opening adjustment of the radiation source hole (4) of the radiation source and lead protective tank (2) and the change in the included angle alpha between the radiation source hole of the radiation source and lead protective tank (2) and a container tank wall ensure that radiation source rays, after emitting from the lead protective tank through the radiation source hole, reach to the probe placed at the other side of the container tank wall not through a container tank body diameter line, but along the chord wire, thereby reducing measuring gap; moreover, the mounting structure greatly reduces radiation source intensity, saves investment and reduces the psychological burden of workers on the spot; in addition, the proposal can also be used in material level detection inside a normal pressure container which has easy fouling and alkali vapor.
Description
Technical field
The utility model relates to the mounting structure of a kind of nuclear radiation level-sensing device on the band pressure vessel.
Background technology
In aluminum oxide production process, medium that is circulated such as ore pulp, sodium aluminate solution, red mud, washing lotion etc., the storage tank of preserving them is easy to scab, and knot is thick more more, and the utmost point is easy cleaning (process equipment is general with the way of beaing) not.Facts have proved; the liquid level of measuring them with the nuclear radiation level-sensing device is an efficient ways; but; install in a conventional way in many engineerings, as shown in Figure 1, the nuclear radiation level-sensing device is installed in the band pressure vessel and surveys on the wall diameter line; one end is placed the source of penetrating of band lead protection jar; the other end is installed the nuclear radiation material level and is accepted probe, accepts the degree that decays in the source of penetrating by probe, and the height of material level in the perception tank body.Because band pressure vessel common tube wall is thicker, device diameters is also bigger, is to guarantee measuring accuracy, need to penetrate source strength also bigger, sometimes up to the hundreds of millicurie.It is big to penetrate source strength, then may endanger its health to approaching people, causes site operation personnel and maintainer to fear, and is reluctant maintenance, repair and debugging.
Summary of the invention
The technical problems to be solved in the utility model is: the mounting structure of a kind of nuclear radiation level-sensing device on the band pressure vessel is provided, this structure can reduce greatly penetrates source strength, with the deficiency that source strength is big, may endanger its health to approaching people of penetrating that overcomes that prior art exists.
The utility model is by the following technical solutions: it comprises container 1, penetrate source and lead protection jar 2, probe 3, She Yuan hole 4 is arranged, the relative position in She Yuan hole 4 and the 3 corresponding settings on the string of a musical instrument of container 1 circumference of popping one's head in penetrating on source and the lead protection jar 2.
Be provided with movable link stopper 5 before the She Yuan hole 4.
The aperture of movable link stopper 5 is 60～85%.
The angle α that penetrates the source of the penetrating center line of source and lead protection jar 2 and container 1 tangent to periphery is between 27 °～35 °.
The aperture in change hole, lead protection jar injection source and with the angle of container tank skin, penetrate source and lead protection jar 2 and probe 3 corresponding settings on the string of a musical instrument of container 1 circumference, make ray without the diameter line of container but the string of a musical instrument arrival of passing through container pop one's head in.
The She Yuan hole aperture of source and lead protection jar 2 is penetrated in adjustment, makes full use of the diverse location of the movable link stopper 5 in 4 places, She Yuan hole on the pig 2, adjusts the orientation that line is penetrated in the source of penetrating, as the fine setting of x-ray angle, in the hope of reaching best measurement effect.
Penetrate the She Yuan hole of source and lead protection jar 2 and the angle α of container 1 tank skin and change to some extent, change the She Yuan hole into perpendicular to the tangent to periphery of tank body and the tank body tangent to periphery has an angle α by original She Yuan hole, along with the change of tank diameter, angle α also changes thereupon.
The beneficial effects of the utility model are as follows: through repacking, and same container, penetrating source strength only needs tens millicuries, greatly reduces and penetrates source strength.This structure is measured the interior material level of band pressure vessel reliability service chronically with the nuclear radiation level-sensing device, reduces greatly and penetrates source strength, saves investment, reduces the psychological burden of field worker.For some easy foulings, the interior material level of non-pressure vessel that has alkali steam detects and also can adopt this scheme.

Fig. 3 is a synoptic diagram of penetrating source and lead protection jar 2, She Yuan hole 4 and movable link stopper 5.
Embodiment
Embodiment of the present utility model: the utility model comprises container 1, penetrate source and lead protection jar 2, probe 3, She Yuan hole 4, movable link stopper 5; as shown in Figure 2; to penetrate source and lead protection jar 2 is installed on container 1 circumference with probe 3; both lines do not pass through diameter; but by the string of a musical instrument, just make ray without the diameter line of container but the string of a musical instrument that passes through container arrives probe.Concrete improvement is as follows: the aperture as the She Yuan hole 4 of move left and right activity link stopper 5 correlation sources and lead protection jar 2 is adjusted, generally between 60～85%.As the fine setting of directions of rays, eliminate because of probe the measuring error that minor deviations is brought is installed, improve measuring accuracy; The She Yuan hole of source and lead protection jar 2 is penetrated in adjustment and the angle α of container 1 tank skin makes ray under the prerequisite that guarantees measuring accuracy, arrives probe with the shortest distance, thereby reduces the required source strength of penetrating greatly; In actual case history,, penetrate the She Yuan hole of source and lead protection jar 2 and the angle α of container 1 tank skin and also change to some extent, between 27 °～35 ° along with the change of container tank skin diameter.When angle α exceeds certain scope, when causing the source of penetrating and lead protection jar 2 certain slit to occur, install stereotype additional penetrating between source lead protection jar and the container tank skin, in the hope of masking the leakage that may occur with the container tank skin.
