Description

Technical Field

[0001] The present invention relates to the technical field of nuclear reactor system equipment, and in particular to a method for efficiently sorting material fragments and a shape measuring device. Background Art

[0002] During the circulation flow of the bulk bed, the interaction between the bulk particles, between the bulk particles and the wall and related equipment pipelines causes friction to act on the surface of the bulk particles, resulting in wear forms such as cutting wear and impact wear on the particle surface, and debris or fragments detaching from the particle surface; in addition, the interaction between turbulence and particles, the mutual influence of particle pulsation and fluid pulsation, and the stability of the particle-to-turbulent boundary layer and the coherent structure of the particle-to-turbulent boundary layer are also factors affecting particle wear. Any changes in the bulk bed under the circulation flow state are very complex, and the bulk particles will be damaged due to impact and collision. In order to ensure the sustainable operation of the system, the circulating bulk particles need to pass through a debris sorting device to remove invalid particles or fragments to ensure the normal operation of the system.

[0003] At present, the debris sorting devices used in engineering are mostly multi-grooved, disc-shaped, rotating sorting devices. By comparing the sensor signal in each groove with the target value, when the target value is not met, the discharge port is opened to discharge the non-conforming material in the groove. When the target is met, the material is sent to the spare material pipeline through the rotation of the device for later use. In this process, it is easy for debris that is too large to remain in the groove, resulting in failure of subsequent sorting. Summary of the invention

[0005] To solve the above technical problems, the present invention provides the following technical solutions: a method for efficiently sorting material fragments, comprising obtaining a first pressure signal value of the material through a first pressure measuring area, and comparing the first pressure signal value with a first target weight value;

[0006] For materials meeting the first target weight value, a second pressure signal value is obtained through a second pressure measuring area, and the second pressure signal value is compared with the second target weight value;

[0007] For materials that meet the second target weight value, the rolling shape of the material is obtained through the shape measurement area. If the rolling shape meets the target shape, the material is collected and stored.

[0009] For materials that do not meet the first target weight value, the shape measuring area does not work. When the material meets the screening size in the fine fragment screening area, it can be directly screened out from the normal path through the fine fragment storage area, and the material enters the fine fragment storage area.

[0014] For materials that meet the target shape, a signal is sent to the steering device.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1 , which is the first embodiment of the present invention, provides a method for efficiently sorting material fragments, which includes:

[0031] S1. Obtain a first pressure signal value of the material through a first pressure measuring area, and compare the first pressure signal value with a first target weight value;

[0032] S2. For materials meeting the first target weight value, obtaining a second pressure signal value through a second pressure measuring area, and comparing the second pressure signal value with the second target weight value;

[0033] Further, after comparing the first pressure signal value with the first target weight value, the method includes:

[0034] For materials that do not meet the first target weight value, the shape measuring area does not work. When the material meets the screening size in the fine fragment screening area, it can be directly screened out from the normal path through the fine fragment storage area, and the material enters the fine fragment storage area.

[0035] S3. For materials that meet the second target weight value, the rolling shape of the material is obtained through the shape measurement area. If the rolling shape meets the target shape, the material is collected and stored.

[0036] Further, after comparing the second pressure signal value with the second target weight value, the method includes:

[0037] For materials that do not meet the second target weight value, the difference signal is transmitted to the steering device, and the steering device determines the spin angle according to the program and transfers the material to the discarded material area.

[0038] Further, the shape measurement area includes a bidirectional measurement device and a speed measurement time area;

[0039] Furthermore, the shape of the material rolling in the shape measuring area is detected in two directions simultaneously by a bidirectional measuring device;

[0040] For materials that meet the target shape, a signal is sent to the steering device. After the steering device receives the passing signal from the shape measurement area, it determines the spin angle according to the program and introduces the qualified materials into the available material area.

[0041] For materials that do not meet the target shape, the material enters the speed measurement time zone

[0042] Furthermore, for materials that do not meet the target shape, the material enters the speed measurement time zone, including:

[0043] After the initial speed is measured by the first speed sensor, the speed of the standard material mass on the slope including the initial speed is calculated, and the speed of the material passing through the second speed sensor is the calculated value. The steering device will spin at a certain angle according to the signal and then be determined by the program to introduce the material into the available material area.

[0044] It should be noted that the material enters the speed measurement time zone, which is mainly composed of two speed sensors. After the first speed sensor measures the initial speed, it can calculate the speed of the standard material mass on the slope including the initial speed and the speed of the material passing through the second speed sensor according to Newton's second law of motion. If the material enters the second speed sensor at a non-calculated specified speed, a non-pass signal is issued. After the material passes through the coarse fragment screening area and the second pressure measuring area, the steering device will spin at a certain angle according to the signal after the program determines to introduce the material into the discarded material area. If the speed passing through the second speed sensor is the calculated value, after the material passes through the coarse fragment screening area and the second pressure measuring area, the steering device will spin at a certain angle according to the signal after the program determines to introduce it into the available material area for later use.

[0045] It should be further explained that if the bidirectional measuring device finds that the shape of the material appears multiple non-target shapes, and the speed signals measured by the second speed sensor do not satisfy the calculated value of Newton's second law of motion, it means that the material exceeding the target weight is composed of multiple defective materials or fragments, and the defective materials or fragments are separated after rolling on the slope. Therefore, this group of materials can be filtered through the coarse fragment screening area, and the part not screened by the coarse fragment screening area, the steering device will also determine the spin at a certain angle according to the program based on the fail signal and discharge the unfiltered material into the discarded material area.

[0046] In summary, the beneficial effect of the method for efficiently sorting material fragments of the present invention is that the equipment and devices related to the present invention can be replaced remotely to ensure the operational safety and personal safety of personnel. Furthermore, the method realizes the measurement of the rolling shape of the material in the measuring area through a two-way measuring device, and the present invention sets a variety of screening areas to ensure that the pipeline is not stuck due to fragments and remains unobstructed.

[0047] Example 2

[0048] Reference Figure 2 , which is the second embodiment of the present invention, and provides a specific structure of the shape measuring device, and the rest is the same as the first embodiment;

[0049] Specifically, the shape measuring device is composed of a group of long rod bundles 100.

[0050] Furthermore, one end of the long rod bundle 100 is composed of an anti-wear rubber head 101, and the other end is marked with a logo 102 of different colors or codes.

[0051] It should be noted that one end of the long rod bundle 100 has a mark 102 of different color or code, so that when several long rod bundles 100 move downward due to the pressure of the material weight, they can be measured by the dual-position measuring device. Within the spatial range of the downward movement of the long rod bundle 100, dual-position measuring devices are arranged in the lateral or guide rail direction, and in the forward or vertical guide rail direction. The shape of the rolling material is detected in both directions at the same time. The dual-position measuring device determines the shape of the rolling material in the measurement area according to the continuous changes of the mark 102 at the lower end of each rod.

[0052] Furthermore, it also includes a return assembly 103 arranged in the lower part of the long rod bundle 100, wherein the return assembly 103 includes but is not limited to a spring, and the return assembly 103 is independently provided with two stages, and also includes a lifting plate (not shown in the drawings) with the same shape as the guide rail surface, and the lifting plate is used to restore the position of each long rod bundle 100 when the spring cannot work normally or loses function. The two-stage setting is to ensure the effectiveness and independence of the return function. Further, the lifting plate, the long rod bundle 100 and their respective springs can be replaced remotely to ensure the operating safety and personal safety of the personnel.

[0053] Furthermore, gaps are provided between the long rod bundles 100 .

[0054] It should be noted that the gaps between the long rod bundles 100 are relatively appropriate to ensure that the rods do not get stuck with each other or get stuck due to small debris when they move up and down, that is, the rods are relatively dense and have a certain spacing. The length of each long rod bundle 100 is long enough to ensure the accessibility of the corresponding circuit and measuring device for maintenance and inspection.

[0055] In summary, the beneficial effects of a shape measuring device of the present invention are that on the one hand, the effectiveness, independence and reliability of the return function are ensured by setting up a two-stage independent return assembly 103, and on the other hand, the shape of the object is transmitted through the long rod bundle 100, and the rolling shape of the object in the shape measuring area is further measured by a bidirectional measuring device.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
