Description
Technical field
The present invention relates to the checkout equipment of fractionator, refer in particular to the radioactive source placing device that a kind of fractionator gamma-rays scanning detects diagnosis usefulness.
Background technology
Oil, Chemical Manufacture enterprise will use a large amount of fractionators; These towers in operational process owing to multiple reasons such as burn into fouling and design defect can produce fault; In order not influence normal production, petroleum chemical enterprise just will detect fractionator often, the fault that exists with elimination.Scan detection with gamma-rays and detect at present more than the fractionator, but the used radioactive source of this detection mode there is very big radiation effects to human body, how in operating process, to avoid radioactive source that the injury of human body has been become a problem that urgency is to be solved.
Summary of the invention
The objective of the invention is to improve and innovate, but a kind of remote-controlled operation is provided, avoid causing the fractionator gamma-rays scanning of radiation to detect the radioactive source placing device of diagnosing usefulness human body to shortcoming that exists in the background technology and problem.
The present invention constructs a kind of fractionator that is arranged at and detects the radioactive source placing device with an end of hoisting gear; Corresponding with the probe of the hoisting gear other end; Comprise shell, handle, internal lining pipe, movable protective block, fixed protection piece, on protect axle and radioactive source, wherein:
Internal lining pipe is arranged on the center of shell, and radioactive source is arranged on internal lining pipe bottom, on protect that axle is arranged in the internal lining pipe, and the top of radioactive source;
Can the be upper and lower mobile setting of described movable protective block in the enclosure, and the outside of internal lining pipe, the fixed protection piece is fixedly installed on the bottom end cover of shell, and the bottom of internal lining pipe;
Described handle is arranged on movable protective block top, and connects the closure or openness of the upper and lower mobile control radioactive source of drive activity protective block.
Advantage of the present invention and beneficial effect:
The present invention is light and handy, rational in infrastructure, uses proof through on-the-spot the detection, and is easy to use and safe and reliable.The present invention utilizes that gamma-rays is distinctive to penetrate and attenuation law; Distinguish whether there is fault in the tower through the variation of density everywhere in the detection fractionator; And the type of fault and position, accomplished under the situation that does not influence ordinary production, fast, accurately diagnose out the fault of existence; Thereby take corresponding measure to eliminate, avoid a large amount of economic losses.The present invention realizes radiogenic open and close through lifting; But remote-controlled operation; Thereby avoided too much closely operating the radiation effect that operating personnel are caused, when device closely moves, can put on rope chain fixing on the end cap; Make radioactive source be in masked state, avoid operating personnel closely to operate and cause excess radiation.

Embodiment
Can know by accompanying drawing 1 to 4; The present invention is arranged at the end that fractionator 1 detects with hoisting gear 2; Corresponding with the probe 3 of hoisting gear 2 other ends, comprise shell 10, handle 4, internal lining pipe 12, movable protective block 9, fixed protection piece 13, on protect axle 8 and radioactive source 11, wherein:
Described movable protective block 9 is can be upper and lower mobile is arranged in the shell 10, and the outside of internal lining pipe 12, and fixed protection piece 13 is fixedly installed on the bottom end cover 14 of shell 10, and the bottom of internal lining pipe 12;
Described handle 4 is arranged on movable protective block 9 tops, and connects the closure or openness of drive activity protective block 9 upper and lower mobile control radioactive sources 11.
Shell of the present invention 10 tops are provided with upper end cover 6, on protect axle 8 and be threaded with upper end cover 6 through set bolt 5.Described upper end cover 6 is provided with the rope chain 15 that closely moves placing device.Described handle 4 connects hoisting gear 2, and is connected with movable protective block 9 through set bolt 7.Described movable protective block 9, fixed protection piece 13 and go up protection axle 8 wolfram steel for having shielding properties.Described shell 10 is processed for stainless steel material with internal lining pipe 12.
Structure of the present invention and principle of work:
The fractionator height that petrochemical industry is used, not of uniform size, high has more than 100 meter high, and big diameter has more than 10 meter, and according to tower diameter and tower wall thickness, the present invention selects the cobalt of several millicuries～hundreds of millicurie for use
60Source or caesium
137The source is detected as the scene and is used radiographic source.Because radiation effects, exposed radiographic source has injury to human body, also will be convenient to simultaneously move up and down.Therefore, detect the requirement of characteristics and safety and environmental protection according to the scene, radiogenic lay operative installations and should have safety, use light, open convenient, be convenient to characteristics such as on-the-spot test.
The present invention is by handle, on protect axle, movable protective block, shell, internal lining pipe, radioactive source, the fixed protection piece, compositions such as rope chain, whole casing and internal lining pipe are processed by stainless steel.Wherein upward protect axle, movable protective block, the fixed protection piece is processed by the splendid wolfram steel of shielding properties, and like this, not only weight is light but also use is safer to use mechanism.Internal lining pipe inner bottom splendid attire radiographic source, on the protection axle is arranged, axle and upper end cover adopt fast-assembling to be threaded, and can take out or change the radiographic source in the internal lining pipe fast.The present invention is divided into unlatching duty and closed shielding off working state.During work; The pulling handle makes movable protective block slide into outer casing top surface, makes radioactive source be in the open working state; Because radiographic source is fan type radiation around the horizontal direction; Be convenient to like this aim at, eliminate that radiographic source misaligns with probe and influence that the swing of radiographic source device, rotation etc. cause, thereby realize the possibility of the on-the-spot detection of fractionator; When closed, movable protective block free-falling shields radioactive source, but makes operating personnel's short time closely handle radiographic source and mechanism.
Embodiment of the present invention only is the description that preferred implementation of the present invention is carried out; Be not that design of the present invention and scope are limited; Under the prerequisite that does not break away from design philosophy of the present invention, engineering technical personnel make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention; The technology contents that the present invention asks for protection all is documented in claims.
