[0008] The path extending from the flow channel passes through multiple detection positions, and the detection components at the detection positions are used to detect the burn-out depth information of the fuel ball; wherein, the control component logically controls the detection components;
[0009] The ball outlet includes a first outlet and a second outlet. The control component controls a target transfer component to transfer the fuel ball from the first outlet or the second outlet based on the burn-out depth information received from the detection component. The target transfer component is the transfer component closest to the ball outlet.
[0010] In some technical solutions, the edge of the transfer component is provided with a bearing port, which is capable of bearing the fuel ball;
[0011] The transfer component is controlled by the control assembly to rotate, so that the bearing port can carry or release the fuel ball.

[0013] In some technical solutions, a gap is provided between the isolation sleeve and the transfer component so that the two form a flow-blocking surface.
[0014] In some technical solutions, a portion of the circumferential surface of the transfer component is recessed to form the bearing port. The bearing port is radially divided into a chip collection groove and a bearing groove. The chip collection groove is closer to the center of the transfer component than the bearing groove. The bearing groove is used to carry the fuel ball, and the chip collection groove is used to collect impurities.
[0015] In some technical solutions, there are multiple carrying ports, which are arranged circumferentially along the transfer component. Each carrying port corresponds to a detection position, and the corresponding detection position is used to detect the burn-out depth information of the fuel ball carried by the corresponding carrying port.
[0016] In some technical solutions, the container is arranged vertically, the ball inlet is located at the top of the container, and the ball outlet is located at the bottom of the container;

[0041] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.
[0042] Existing positioning dispensers have low efficiency in detecting fuel ball alignment. Therefore, to improve the efficiency of fuel ball detection and dispensing, such as... Figure 1 As shown, this application provides a dispenser that may include a container 10 and a transfer assembly 20.
[0043] like Figure 2 As shown, the container 10 is constructed with a cavity 11, and has an inlet 12 and an outlet 13 connected to the cavity 11; the inlet 12 is used to introduce the fuel ball 40, and the outlet 13 is used to discharge the fuel ball 40.
[0044] like Figure 2 As shown, the transfer assembly 20 may include: a transfer component 21 disposed in the cavity 11; there are multiple transfer components 21, which are arranged along the flow channel, which is the channel through which the fuel ball 40 flows from the inlet 12 to the outlet 13; wherein, the transfer component 21 is used to be electrically connected to the control assembly, and the control assembly controls the transfer component 21 to operate according to a preset pattern as required.
[0045] The path of the flow channel extends through multiple detection positions, and the detection components at the detection positions are used to detect the burn-out depth information of the fuel ball 40; wherein, the control component logically controls the detection components to regulate the working state of the detection components and detect the burn-out depth information of the fuel ball 40.
[0046] The ball outlet 13 may include a first outlet 131 and a second outlet 132. The control component controls the target transfer component to transfer the fuel ball 40 from the first outlet 131 or the second outlet 132 based on the burn depth information received from the detection component. The target transfer component is the transfer component 21 closest to the ball outlet 13.
[0047] In this technical solution, multiple transfer components 21 are arranged sequentially along the flow channel within the cavity 11 of the container 10, allowing the fuel balls 40 to enter from the inlet 12, pass through each transfer component 21, and then exit from the outlet 13. In this technical solution, the dispenser is installed in an operating system with control and detection components. During use, the fuel balls 40 are detected by the detection components during flow to obtain corresponding burn-out depth information. Based on the burn-out depth information of each fuel ball 40, the control component controls the target transfer components to discharge fuel balls 40 with different burn-out depth information from the first outlet 131 and the second outlet 132 respectively, thus achieving automatic distribution and improving the efficiency of detection and distribution.
[0048] Based on the above technical solutions, such as Figure 2 As shown, in order to make the fuel ball 40 transfer quick and convenient, the edge of the transfer component 21 is constructed with a bearing port 211, which can bear the fuel ball 40.
[0049] like Figure 2 As shown, the transfer component 21 is controlled by the control component to rotate, so that the carrying port 211 can carry or release the fuel ball 40. In use, the carrying port 211 has at least three states during rotation: carrying state, detection state, and release state. When the carrying port 211 is in the carrying state, it carries the fuel ball 40. When it is in the detection state (i.e., the carrying port 211 is in the detection position, and the detection position is equipped with a detection component), the detection component detects the fuel ball 40 to obtain the burn-out depth information and sends the burn-out depth information to the control component. When it is in the release state, the carrying port 211 releases the fuel ball 40 so that the fuel ball 40 enters the adjacent transfer component 21 or is discharged from the first outlet 131 or the second outlet 132.
[0050] In a technical solution, such as Figure 2As shown, the transfer assembly 20 may further include: an isolation sleeve 22 disposed within the cavity 11, the isolation sleeve 22 having an inlet through-hole and an outlet through-hole; the transfer member 21 is constructed as a cylindrical structure and is located within the isolation sleeve 22, and is rotatable relative to the isolation sleeve 22. In this technical solution, when the bearing port 211 is in the bearing state, the bearing port 211 is connected to the inlet through-hole to bear the fuel ball 40 entering from the inlet through-hole; when the bearing port 211 is in the release state, the bearing port 211 is connected to the outlet through-hole to release the fuel ball 40 located within the bearing port 211, and the fuel ball 40 is discharged through the outlet through-hole. It should be noted that the target transfer member has two outlet through-holes, which respectively lead to the first outlet 131 and the second outlet 132. Figure 2 As shown. In addition, the isolation sleeve 22 can be constructed as a cylindrical isolation sleeve, and the isolation sleeve 22 can be made of a non-pressure-bearing hard alloy layer (wear-resistant layer).
[0051] To avoid the impact of movement between the transfer component 21 and the isolation sleeve 22, a gap is provided between the isolation sleeve 22 and the transfer component 21 to form a flow-blocking surface. This flow-blocking surface creates a very small gap between the isolation sleeve 22 and the transfer component 21, resulting in a small pressure difference before and after the flow-blocking surface, isolating helium gas flow and preventing core helium gas from circulating through the fuel loading and unloading system. In this technical solution, the distributor simultaneously has the functions of flow blocking and distribution. The flow-blocking surface formed between the transfer component 21 and the isolation sleeve 22 can be formed between at least one transfer component 21 and its corresponding isolation sleeve 22.
[0052] To prevent impurities from affecting the smooth flow of fuel pellets 40 during transport, such as Figure 3 As shown, a portion of the circumferential surface of the transfer component 21 is recessed to form a bearing port 211. The bearing port 211 is radially divided into a chip collection groove 212 and a bearing groove 213. The chip collection groove 212 is closer to the center of the transfer component 21 than the bearing groove 213. The bearing groove 213 is used to carry the fuel ball 40, and the chip collection groove 212 is used to collect impurities. In this technical solution, the chip collection groove 212 is used to collect impurities, which makes the transfer process of the fuel ball 40 smoother.
[0053] Based on the above technical solution, in order to simultaneously detect the burnup depth information of multiple fuel balls 40, such as Figure 5 and Figure 6As shown, there are multiple carrying ports 211 arranged circumferentially along the transfer member 21. Each carrying port 211 corresponds to a detection position (i.e., the corresponding carrying port 211 can stay in the corresponding detection position). The corresponding detection position is used to detect the burn-out depth information of the fuel ball 40 carried by the corresponding carrying port 211. In use, when multiple carrying ports 211 on a transfer member 21 are carrying fuel balls 40, when each carrying port 211 is in the detection state, the detection components on each detection position detect the fuel ball 40 to obtain the burn-out depth information.
[0054] Regarding the fit between the fuel ball 40 and the bearing port 211, the bearing port 211 may be equipped with a clamping structure, which can clamp or release the fuel ball 40. To simplify the structure and save costs, a bearing port 211 without a clamping structure may be constructed, such as... Figure 1 As shown, the container 10 is arranged vertically, with the ball inlet 12 located at the top of the container 10 and the ball outlet 13 located at the bottom of the container 10.
[0055] The inlet hole is located at the top of the isolation sleeve 22, and the outlet hole is located at the bottom of the isolation sleeve 22. During use, under the action of gravity, the fuel ball 40 flows from the inlet 12 to the bearing port 211, then from the bearing port 211 to the adjacent bearing port 211, and then from the bearing port 211 to the outlet 13, using gravity to make the fuel ball 40 flow.
[0056] To improve allocation efficiency, such as Figure 6 As shown, adjacent transfer components 21 are connected by a transfer channel 30, through which fuel balls 40 pass. A portion of the transfer channel 30 extends along a detection station, where a detection component can detect the passing fuel balls 40. Figure 5 As shown.
[0057] In order to improve the distribution efficiency of fuel balls 40, such as Figure 1 As shown, there are three transfer components 21, namely the first transfer component 21, the second transfer component 21, and the third transfer component 21 arranged along the flow channel;
[0058] The first transfer component 21 can transfer the fuel ball 40 in the inlet 12 to the second transfer component 21 according to the first motion trajectory. The detection component located in the first motion trajectory is used to detect the burn-out depth information of the fuel ball 40.
[0059] The second transfer component 21 can transfer the fuel ball 40 carried in the first transfer component 21 to the third transfer component 21 according to the second motion trajectory. The detection component located in the second motion trajectory is used to detect the burn-out depth information of the fuel ball 40.
[0060] The third transfer component 21 can transfer the fuel ball 40 carried in the second transfer component 21 to the ball outlet 13 according to the third motion trajectory. The detection component located in the third motion trajectory is used to detect the burn-out depth information of the fuel ball 40. The third transfer component 21 is the target transfer component.
[0061] In the above technical solution, the control component controls the movement trajectory of the transfer component 21. In use, the control component controls different transfer components 21 so that each transfer component 21 carries a different fuel ball 40. The detection component located in the first movement trajectory detects the fuel ball 40's burn-out depth information as first information; the detection component located in the second movement trajectory detects the fuel ball 40's burn-out depth information as second information; and the detection component located in the third movement trajectory detects the fuel ball 40's burn-out depth information as third information. Based on the first, second, and third information, the control component controls the corresponding fuel ball 40 to be discharged from the first outlet 131 or the second outlet 132. The control component can be set with a preset burn-out depth information value. If the detected burn-out depth information exceeds the preset burn-out depth information value, the corresponding fuel ball 40 is discharged from the first outlet 131; if the burn-out depth information does not exceed the preset burn-out depth information value, the corresponding fuel ball 40 is discharged from the second outlet 132. Furthermore, the first motion trajectory can be a unidirectional clockwise or counterclockwise motion trajectory, the second motion trajectory can be a unidirectional clockwise or counterclockwise motion trajectory, and the third motion trajectory can include clockwise motion trajectory, counterclockwise motion trajectory, and bidirectional swing motion trajectory. When the fuel ball 40 needs to be discharged from the first outlet 131, the third motion trajectory is a clockwise motion trajectory; when the fuel ball 40 needs to be discharged from the second outlet 132, the third motion trajectory is a counterclockwise motion trajectory. The path extending from the flow channel passes through multiple detection positions, and these multiple detection positions simultaneously detect the fuel ball, further shortening the average detection time and improving detection efficiency.
[0062] In a technical solution, such as Figure 4 As shown, the transfer component 21 may further include: a transfer component body, a motor 26, a reducer 23, a coupling 24, and a magnetic synchronizer 25. The motor 26 outputs power, which is reduced and amplified by the reducer 23, and then connected to the magnetic synchronizer 25 via the coupling 24 to achieve power transmission. The magnetic synchronizer 25 employs non-contact magnetic coupling transmission, transmitting the rotational torque at the input end to the output end without contact through magnetic field coupling, thus driving the transfer component 21 to rotate synchronously. The motor 26 controls the transfer component body to be positioned at a specific location, which coincides with the detection position, so that the detection component at the detection position can detect the fuel ball 40. The transfer component body has a carrying port 211, a chip collection groove 212, and a carrying groove 213, etc.
[0063] An allocation method that detects allocations based on the allocator described above.
[0064] Allocation methods include:
[0065] Obtain the test requirements.
[0066] The control transfer component 21 and the detection components on the detection position operate according to a preset pattern.
[0067] Based on the above principles, in a specific solution, such as Figure 5 As shown, three transfer components 21 are arranged along the flow channel. A detection component is also provided in the transfer channel 30 between the first and second transfer components 21. In use, the burnup depth information of four fuel balls 40 can be detected simultaneously. The first fuel ball 40 flows to the third transfer component 21 (the first fuel ball 40 is in the detection position), the second fuel ball 40 flows to the second transfer component 21 (the second fuel ball 40 is in the detection position), the third fuel ball 40 flows to the transfer channel 30 (the third fuel ball 40 is in the detection position), and the fourth fuel ball 40 flows to the first transfer component 21 (the fourth fuel ball 40 is in the detection position). When each fuel ball is in the detection position, the burnup depth information is simultaneously detected. Based on the burnup depth information, the control component controls the corresponding fuel ball to be discharged from the first outlet 131 or the second outlet 132. The detection component can be a burnup depth detection sensor.
[0068] In another specific embodiment, such as Figure 6 As shown. Multiple detection positions can be set in the flow channel, and each detection position is equipped with a fuel consumption depth detection sensor. In this way, multiple fuel balls 40 can be detected simultaneously to obtain fuel consumption depth information. The specific detection principle can be referred to above, and will not be described in detail here.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

"And / or" in this article is merely a description of the relationship between related objects, indicating that there can be three relationships.
