[0038] It should be noted that the steel ball retrieval and filling system of the present invention can be applied not only to the retrieval and filling of steel balls in steel ball reactors, but also to the retrieval and filling of steel balls in other similar containers, which will not be elaborated here.

[0039] Example 1

[0040] like Figure 1 , Figure 2 As shown, this embodiment discloses a steel ball retrieval and filling system, including a suction device 4 and an intermediate container 10. The inlet end of the suction device 4 is provided with a first suction line 51 and a second suction line 52, and the outlet end of the suction device 4 is provided with a first outlet line 81 and a second outlet line 82.

[0041] The suction device 4 is inserted into the steel ball reactor 7 through the first suction pipe 51 to retrieve steel balls from the steel ball reactor; the top of the intermediate container 10 is provided with a steel ball inlet 101, and the steel ball inlet 101 is provided with a first valve 91. The steel ball inlet 101 of the intermediate container 10 is connected to the suction device 4 through the first outlet pipe 81 to receive the steel balls retrieved by the suction device from the steel ball reactor.

[0042] The top of the intermediate container 10 is also provided with a steel ball outlet 102, which is equipped with a second valve 92. The suction device 4 is also inserted into the intermediate container 10 through the steel ball outlet 102 at the top of the intermediate container 10 via a second suction pipe 52, for sucking out steel balls from the intermediate container. The suction device 4 is also connected to the steel ball reactor 7 via a second ball outlet pipe 82, for filling the steel balls sucked out from the intermediate container into the steel ball reactor.

[0043] In some embodiments, the suction device 4 is positioned at a height greater than that of the intermediate container 10, so that the steel balls retrieved by the suction device can fall into the intermediate container by their own weight through the feed pipe at the top of the intermediate container for temporary storage.

[0044] In some embodiments, the suction device 4 is an industrial vacuum cleaner, but it is not limited to this and may be other devices with similar functions.

[0045] In some embodiments, a vibrator 6 is provided on the first suction pipe 51. When retrieving the steel ball, the vibrator is turned on, which can increase the disturbance of the steel ball without the need for the operator to stand by and operate it manually. This prevents the steel ball from bridging and getting stuck at the opening of the first suction pipe, thus eliminating the bridging problem.

[0046] In some implementations, a vibrator 6 is also provided on the second suction line 52 to eliminate bridging problems.

[0047] In some embodiments, both the first suction line 51 and the second suction line 52 are equipped with endoscopes (not shown in the figure) to observe the suction of the steel balls in the corresponding lines.

[0048] In some embodiments, the system further includes an exhaust gas filter 1, the inlet end of which is provided with a first exhaust duct 111, and the intermediate container 10 is provided with an exhaust port 103. The exhaust gas filter 1 is connected to the exhaust port 103 of the intermediate container 10 through the first exhaust duct 111, and is used to filter and discharge the gas drawn out of the steel ball reactor by the suction device when the steel balls are retrieved.

[0049] In some embodiments, the exhaust gas filter 1 is provided with a second exhaust duct 112 at its inlet end. The exhaust gas filter 1 is also connected to the steel ball reactor 7 through the second exhaust duct 112, which is used to filter and discharge the gas drawn out of the intermediate container by the suction device during the filling of steel balls.

[0050] In some embodiments, the first exhaust duct 111 and the second exhaust duct 112 may each be equipped with a set of exhaust fan 2 and exhaust valve 3; alternatively, the first exhaust duct 111 and the second exhaust duct 112 may share a set of exhaust fan 2 and exhaust valve 3 to reduce the number of devices and reduce costs.

[0051] In some embodiments, the intermediate container 10 is provided with a lifting lug 104.

[0052] The working process of the steel ball retrieval and loading system in this embodiment is described in detail below, and includes the following features:

[0053] Steel ball retrieval process:

[0054] Open the exhaust valve 3, connect the first exhaust pipe 111 to the exhaust port 103 of the intermediate container 10, open the first valve 91, close the second valve 92, insert the first ball suction pipe 51 into the steel ball reactor 7, and connect the first ball outlet pipe 81 to the steel ball inlet 101 of the intermediate container 10; then, start the exhaust fan 2, vibrator 6 and industrial vacuum cleaner (i.e., suction device 4), observe the steel ball suction situation through the endoscope on the first ball suction pipe 51, and intervene manually if necessary, and finally complete the process of retrieving the steel balls from the steel ball reactor 7 to the intermediate container 10.

[0055] Steel ball loading process:

[0056] Open the exhaust valve 3, connect the second exhaust duct 112 to the steel ball reactor, open the second valve 92, close the first valve 91, insert the second ball suction duct 52 into the intermediate container 10 through the steel ball outlet 102, and connect the second ball outlet duct 82 to the steel ball reactor 7; then, start the exhaust fan 2, vibrator 6 and industrial vacuum cleaner (i.e., suction device 4), observe the steel ball suction situation through the endoscope on the second ball suction duct 52, and intervene manually if necessary, and finally complete the process of filling the steel balls in the intermediate container 10 into the steel ball reactor 7.

[0057] The steel ball retrieval and loading system implemented herein has at least the following effects:

[0058] (1) It can improve efficiency and does not require personnel to operate on-site, making it safer. It can be applied to the steel ball retrieval and filling of steel ball reactors in radioactive environments.

[0059] (2) By setting up a vibrator, it is not necessary for the operator to stand by and disturb the steel ball.

[0060] (3) By setting up exhaust gas filters and exhaust pipes, a dust collection and exhaust gas filtration system can be formed, which can prevent the large-scale spread of radioactive gases.

[0061] (4) The intermediate container can be used as a temporary container for holding steel balls during the retrieval and filling process, or as a waste bin for holding waste steel balls for subsequent waste treatment, which can reduce the number of equipment and reduce costs.

[0062] Example 2

[0063] This embodiment discloses a radioactive waste treatment device, including a steel ball reactor 7, and the steel ball retrieval and loading system described above.

[0064] Specifically, the top of the ball reactor is equipped with a nozzle and a ball inlet / outlet. A second exhaust duct 112 is connected to the ball reactor 7 via the nozzle at the top. When ball retrieving is required, the ball inlet / outlet at the top of the ball reactor 7 is opened, and the first ball suction duct 51 is inserted into the ball reactor 7 via the ball outlet at the top to retrieve the ball. When ball filling is required, the ball inlet / outlet at the top of the ball reactor 7 is opened, and the second ball outlet duct 82 is connected to the ball reactor 7 via the ball inlet at the top, and the steel balls in the intermediate container 10 are filled into the ball reactor via the suction device 4.

[0065] The radioactive waste treatment apparatus of this embodiment, since it includes the steel ball retrieval and filling system described above, also has the above-mentioned effects, which will not be repeated here.

[0066] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
