Abstract
The utility model discloses an under-beam irradiation device for pipes, comprising a bracket, active pinions, a scanning window and a pipe, wherein the length of the scanning window and the longitudinal direction of the pipe are arranged in up-down parallel; one end of the bracket is provided with the active pinions; the active pinions are arranged lengthways along the pipe; every column of the active pinions is at an identical angle to the pipe; the active pinions are arranged in a spiral shape with equivalent thread pitch; the pipe is jammed by the active pinions; the pipe is rotated and translated along a straight line. The irradiation device has the advantages that: as the bracket can stretch or retract along the axis of the pipe, the pipes can all be clamped by the active pinions, rotated and translated, regardless of the size of pipe diameter; meanwhile, as the length direction of the scanning window and the longitudinal direction of the pipe are arranged in parallel, the irradiation device is more even in pipe irradiation and stronger in penetrating power of irradiation.
Description
Technical field
The utility model relates to a kind of irradiation devices, particularly relates to irradiation devices under a kind of bundle that is used for tubing.
Background technology
Tubing is because the place difference that is suitable for, the performance requirement of tubing is also inequality, some tubing need carry out radiation treatment before use, at present the radiation treatment of tubing is normally packed into tubing in the dolly, when car and the irradiation devices in moving process of the tubing on the dolly are perpendicular, irradiation devices carry out treatment with irradiation to tubing, when tubing need rotate, need just can carry out the multiaspect irradiation by artificial lift to move, cause inefficiency like this, can't carry out continuous irradiation in enormous quantities, working strength of workers is big; Generally needing the caliber of irradiation in the operation is Φ 50-Φ 400mm, pipe thickness is mostly more than 3mm, and existing equipment can only be handled the tubing of caliber at Φ 200mm, make the irradiation caliber be subjected to certain limitation, the irradiation uniformity coefficient of tubing is poor simultaneously, as shown in Figure 1, its external dose/interior dosage ≈ α/θ can't be penetrated the side string of tube wall.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the prior art shortcoming, provides a kind of penetration power strong, the caliber wide ranges, and irradiation is even, irradiation devices under the high tubing bundle of efficient.
The technical scheme that the utility model adopted is: irradiation devices under a kind of tubing bundle comprise support, active steamboat, scanning window and tubing; The length and the tubing of described scanning window vertically be arranged in parallel up and down, one end of described support is equipped with initiatively steamboat, described active steamboat is vertically arranged along tubing, every row all form identical angle with tubing, be aligned to the spiral fashion that pitch equates, described active steamboat blocks tubing, and tubing rotates translation along straight line.
Described irradiation devices also include support arm, and described support arm equates described support arm diameter be Φ 220mm, Φ 320mm, Φ 420mm or Φ 520mm with the active steamboat with the pitch that pipe forms with the support steamboat.
Be provided with spring between described support and the active steamboat, described support arm becomes 45 degree to be provided with the support steamboat; Described active steamboat is provided with 4 to 8 row along tubing, and its surface is a rubber, and its diameter is 80-100mm, and rotating speed is that 200-800 changes.
The beneficial effects of the utility model are: because support can be flexible along the tubing axis, guarantee no matter caliber size tubing all can be clamped by the active steamboat and the rotation translation, simultaneously, the length direction and the tubing parallel longitudinal of scanning window are provided with, more even when making tubing irradiation, and the penetration power of its irradiation is stronger.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
To shown in Figure 7, irradiation devices under the utility model tubing bundle comprise support 4, active steamboat 1, scanning window 3 and tubing 2 as Fig. 2; The length of described scanning window 3 and tubing 2 vertically be arranged in parallel up and down, one end of described support 4 is equipped with initiatively steamboat 1, initiatively steamboat 1 is detachable, described active steamboat 1 is vertically arranged along tubing 2, every row all form identical angle with tubing 2, and are aligned to spiral fashion, and initiatively steamboat 1 rotates, tubing 2 will produce translation in rotating process, initiatively the point-to-point speed of the rotating speed of steamboat 1 decision tubing; Outer moving frame 5 is used to support the driving wheel part, and described active steamboat blocks tubing, and tubing is realized the purpose of even irradiation along straight line rotation, rotation and translation.Described support 4 with initiatively be provided with spring between the steamboat or by being threaded, support 4 can suitably be regulated according to tubing 2 diameters, as hour screw tight screw (support) when caliber, when caliber is big, unscrew screw (support), that is, support is flexible along the axis of tubing, as long as guarantee that initiatively steamboat closely contacts with tubing, described support arm 10 is used to support 6 one-tenth 45 degree of follower part and support steamboat and is provided with, and guarantees that initiatively the drift angle of steamboat is consistent with the tangent plane of tubing; Described active steamboat 1 is provided with 4 to 8 row along tubing, and its surface is a rubber, and its diameter is 80-100mm, and rotating speed can be adjusted between 200-800 changes.The diameter of described support arm 10 is Φ 220mm, Φ 320mm, Φ 420mm, Φ 520mm.
This device can improve the line utilization factor, every pipe interval 5cm when continuous irradiation, length 1m, the line utilization factor can reach more than 80%, and existing with the 15KW accelerator, the absorbed dose of tubing is that 10Mrad is an example, the working ability of pipe is 400KG/ hour, deducting and get in stocks and following ETCD estimated time of commencing discharging, is 4 tons/every day, and can reach 1000 tons working ability every year.Scanning being divided into several sections n being the turn-take number of pipe balance by scanning) every section stack gained uniformity coefficient is pipe girth gained uniformity coefficient, should be better than the uniformity coefficient of scanning itself.Get greater than 10 with n, pipe diameter 110mm is an example, and the point-to-point speed of tubing is greater than the 2m per minute, and the rotation of pipe should be greater than 40, and the uniformity coefficient of irradiation can reach more than 95%, and the utilization factor of line is greater than 80%.
The principle of work of irradiation devices is under the bundle of tubing: tubing bundle lower device is activated, hopper and charging motor rotate, snap ring opens the beginning charging, the active steamboat blocked tubing after pipe put in place, along with the translation tubing of tubing is restrainted down irradiation, after tubing is by irradiation, leave initiatively steamboat, initiatively steamboat can unclamp, tubing is unloaded goods, and irradiation devices carry out tubing irradiation next time.
It is worthy of note; protection domain of the present utility model is not limited to above-mentioned instantiation mode; according to basic fundamental design of the present utility model; also available essentially identical structure such as tubing also can pass through driving wheel, support wheel, belt drive tubing rotation translation; so long as those of ordinary skills need not through creative work; the embodiment that can associate all belongs to protection domain of the present utility model.
