Description

Technical Field

[0001] The invention mainly relates to the technical field of coal quality detection and analysis, and in particular to an ash fusibility tester and an imaging method thereof. Background Art

[0002] The ash fusion tester is an instrument used to detect the fusibility of the ash cone of a coal sample. The fusibility of the ash cone is directly related to whether the boiler of a power plant is sintered and the severity of the sintering, and has a great impact on the safe use of boilers and cement kilns. In the ash fusion tester in the prior art, the ash cone sample is set on a support plate, and the support plate is set on a support cup. During the test, the support cup drives the support plate to rotate, so that the ash cone sample rotates in the constant temperature zone of the high-temperature furnace tube and is evenly heated until the ash cone of the coal sample reaches a molten state. In this process, the camera mechanism takes pictures in real time, and through computer or manual analysis, the temperatures of the four characteristic points of deformation, softening, hemisphere and flow of the coal sample are obtained.

[0003] In the existing ash fusion tester, an image tube is provided on the side of the furnace tube close to the camera, and a background tube is provided on the side opposite to the image tube. The temperature of the background tube is relatively low, and the brightness of the background tube is limited at low temperatures, so that the background tube is distinguished from the sample and the relatively dark background of the surrounding support plate and furnace tube, which is used for the camera to identify the sample. However, the ash fusion tester in the prior art still has the following disadvantages:

[0004] 1. The temperature of the background tube decreases gradually from close to the ash cone to far away from the end of the ash cone. Therefore, the relative brightness contrast between the background tube and the sample and the surrounding support plate and furnace tube also changes from basically the same color brightness to a relatively dark background, which reduces the recognition accuracy of the camera.

[0005] 2. The setting of the background tube makes the design of the furnace tube complicated and reduces the reliability. Summary of the invention

[0006] In view of the technical problems existing in the prior art, the present invention provides an ash fusibility tester and an imaging method thereof which have a simple structure, high testing efficiency and higher sample image recognition accuracy.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] An ash fusibility tester comprises a high-temperature furnace, a furnace tube assembly, an electromagnetic wave generating mechanism, an electromagnetic wave receiving mechanism, a specific electromagnetic wave passing mechanism and an ash cone support assembly, wherein the furnace tube assembly is arranged in the high-temperature furnace, the ash cone support assembly is arranged in the furnace tube assembly, a rotating mechanism for driving the ash cone support assembly to rotate in the furnace tube assembly is arranged below the ash cone support assembly, the electromagnetic wave generating mechanism is located in the middle of the ash cone support assembly, the electromagnetic wave emitted by the electromagnetic wave generating mechanism is directed toward a sample on the ash cone support assembly, and the electromagnetic wave receiving mechanism obtains the electromagnetic wave emitted by the electromagnetic wave generating mechanism through the specific electromagnetic wave passing mechanism and analyzes and obtains an image of the sample.

[0009] As a further improvement of the present invention: the furnace tube assembly includes a sample cavity and an imaging cavity for accommodating samples.

[0010] As a further improvement of the present invention: the electromagnetic wave receiving mechanism is arranged at one side of the imaging cavity, and the specific electromagnetic wave passing mechanism is arranged between the electromagnetic wave receiving mechanism and the imaging cavity.

[0011] As a further improvement of the present invention: a lens plate for sealing the furnace tube assembly is provided at the imaging port of the imaging cavity.

[0012] As a further improvement of the present invention: the electromagnetic wave receiving mechanism is arranged at one side of the imaging cavity, and the specific electromagnetic wave passing mechanism is arranged at the imaging port of the imaging cavity.

[0013] As a further improvement of the present invention: the electromagnetic wave generating mechanism includes a transmitting component and a power supply component, and the two ends of the transmitting component are respectively connected to the positive and negative poles of the power supply component.

[0014] As a further improvement of the present invention: the electromagnetic wave generating mechanism comprises a transmitting source and an outer cover of the transmitting body, and the transmitting source is arranged inside the outer cover of the transmitting body.

[0015] As a further improvement of the present invention: the electromagnetic wave generating mechanism comprises an inner core of an emitter, and the outer surface of the inner core of the emitter is provided with a coating.

[0016] As a further improvement of the present invention: it also includes a temperature measuring mechanism, and the temperature measuring mechanism is arranged in the high-temperature furnace.

[0017] The present invention also provides an imaging method of the ash fusibility tester as described above, comprising the following steps:

[0018] S1: The electromagnetic wave generating mechanism emits electromagnetic waves;

[0019] S2: drives the ash cone support assembly to rotate;

[0020] S3: The electromagnetic wave receiving mechanism obtains the electromagnetic wave emitted by the electromagnetic wave generating mechanism through a specific electromagnetic wave passing mechanism;

[0021] S4: The electromagnetic wave receiving mechanism decodes the received electromagnetic wave to obtain an image of the sample between the electromagnetic wave generating mechanism and the electromagnetic wave receiving mechanism.

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] The ash fusibility tester of the present invention eliminates the camera mechanism in the prior art. An electromagnetic wave generating mechanism is arranged in the furnace tube assembly and an electromagnetic wave receiving mechanism is arranged outside the furnace tube assembly. The sample on the ash cone support assembly is driven by the rotating mechanism to be rotated between the electromagnetic wave generating mechanism and the electromagnetic wave receiving mechanism. Since the electromagnetic wave emitted by the electromagnetic wave generating mechanism is significantly different from the electromagnetic waves emitted by the sample and the surrounding ash cone support assembly and the furnace tube assembly, a specific electromagnetic wave passing mechanism is added in front of the electromagnetic wave receiving mechanism. The specific electromagnetic wave passing mechanism can only pass the electromagnetic waves with the same wavelength as that emitted by the electromagnetic wave generating mechanism in the furnace tube assembly, so that the electromagnetic wave receiving mechanism can only receive the electromagnetic waves with the specific wavelength emitted by the electromagnetic wave generating mechanism in the furnace tube assembly. Since the sample blocks part of the electromagnetic waves emitted by the electromagnetic wave generating mechanism, the electromagnetic waves received by the electromagnetic wave receiving mechanism are changed. The sample image is obtained by decoding the electromagnetic wave, thereby solving the problems of low recognition accuracy of the camera mechanism of the existing ash fusibility tester and complex furnace tube structure design. In addition, the sample arrangement on the ash cone support assembly can be more compact, and each ash cone support assembly can hold more samples, thereby improving the test efficiency.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Embodiment 1

[0033] like Figure 1 As shown, this embodiment discloses an ash fusibility tester, including a high-temperature furnace, a furnace tube assembly 1, an electromagnetic wave generating mechanism 2, an electromagnetic wave receiving mechanism 3, a specific electromagnetic wave passing mechanism 4 (i.e., a mechanism that can pass electromagnetic waves within a certain wavelength range) and an ash cone support assembly 5. The furnace tube assembly 1 is arranged in the high-temperature furnace, the ash cone support assembly 5 is arranged in the furnace tube assembly 1, and a rotating mechanism for driving the ash cone support assembly 5 to rotate in the furnace tube assembly 1 is provided below the ash cone support assembly 5. The electromagnetic wave generating mechanism 2 is located in the middle of the ash cone support assembly 5, and the electromagnetic wave emitted by the electromagnetic wave generating mechanism 2 is directed to the sample on the ash cone support assembly 5. The electromagnetic wave receiving mechanism 3 obtains the electromagnetic wave emitted by the electromagnetic wave generating mechanism 2 through the specific electromagnetic wave passing mechanism 4 and analyzes it to obtain an image of the sample.

[0034] The ash fusibility tester provided in this embodiment is provided with an electromagnetic wave generating mechanism 2 in the furnace tube assembly 1 and an electromagnetic wave receiving mechanism 3 outside the furnace tube assembly 1. The sample on the ash cone support assembly 5 is driven by the rotating mechanism to be transferred to the space between the electromagnetic wave generating mechanism 2 and the electromagnetic wave receiving mechanism 3. Since the electromagnetic wave emitted by the electromagnetic wave generating mechanism 2 is significantly different from the electromagnetic wave emitted by the sample and the surrounding ash cone support assembly 5 and the furnace tube assembly 1, a specific electromagnetic wave passing mechanism 4 is added in front of the electromagnetic wave receiving mechanism 3. This specific electromagnetic wave passing mechanism 4 can only pass through the electromagnetic wave in the furnace tube assembly 1. The generating mechanism 2 emits electromagnetic waves of the same wavelength, so that the electromagnetic wave receiving mechanism 3 can only receive electromagnetic waves of a specific wavelength emitted by the electromagnetic wave generating mechanism 2 in the furnace tube assembly 1. Since the sample blocks part of the electromagnetic waves emitted by the electromagnetic wave generating mechanism 2, the electromagnetic waves received by the electromagnetic wave receiving mechanism 3 are changed. The sample image is obtained by decoding the electromagnetic wave, which solves the problems of low recognition accuracy of the existing camera mechanism of the ash fusibility tester and complex furnace tube structure design. The sample arrangement on the ash cone support assembly 5 can be more compact, and each ash cone support assembly 5 can hold more samples, thereby improving the test efficiency.

[0035] In this embodiment, the furnace tube assembly 1 includes a sample chamber 11 for accommodating samples and an imaging chamber 12, an electromagnetic wave receiving mechanism 3 is arranged on one side of the imaging chamber 12, and a specific electromagnetic wave passing mechanism 4 is arranged between the electromagnetic wave receiving mechanism 3 and the imaging chamber 12. A lens plate 6 for sealing the furnace tube assembly 1 is provided at the imaging port of the imaging chamber 12, and an air inlet is provided near the imaging port of the imaging chamber 12. The furnace tube assembly 1 of this embodiment forms a cavity with a certain degree of closure through the lens plate 6.

[0036] In this embodiment, a temperature measuring mechanism 7 (such as a thermocouple) is further included, and the temperature measuring mechanism 7 is arranged in the high temperature furnace. Further, in a preferred embodiment, the temperature measuring mechanism 7 is inserted into the furnace tube assembly 1 through the tube wall of the furnace tube assembly 1 .

[0037] Implementation II

[0038] This embodiment is basically the same as the first embodiment, except that this embodiment further optimizes the electromagnetic wave generating mechanism 2. Figure 2 As shown, the electromagnetic wave generating mechanism 2 in this embodiment is made of an electrified material, and includes a transmitting component and a power component, and the two ends of the transmitting component are respectively connected to the positive and negative electrodes of the power component. When the power component is turned on, the transmitting component emits electromagnetic waves that are significantly different from the surrounding environment.

[0039] Embodiment 3

[0040] This embodiment is basically the same as the first embodiment, except that this embodiment further optimizes the electromagnetic wave generating mechanism 2. Figure 3 As shown, the electromagnetic wave generating mechanism 2 in this embodiment includes a transmitting source and an outer emitter cover. The transmitting source is arranged at the bottom of the outer emitter cover, and the electromagnetic wave is emitted to the sample on the ash cone support assembly 5 through the outer emitter cover.

[0041] Embodiment 4

[0042] This embodiment is basically the same as the first embodiment, except that this embodiment further optimizes the electromagnetic wave generating mechanism 2. Figure 4 As shown, the electromagnetic wave generating mechanism 2 includes an inner core of the emitter, and the outer surface of the inner core of the emitter is provided with a coating 21, so that the electromagnetic waves emitted by the emitter are significantly different from the electromagnetic waves emitted by the surrounding environment.

[0043] Embodiment 5

[0044] like Figure 5 As shown, this embodiment is basically the same as the first embodiment, except that, in this embodiment, the electromagnetic wave receiving mechanism 3 is arranged at one side of the imaging cavity 12, and the specific electromagnetic wave passing mechanism 4 is arranged at the imaging port of the imaging cavity 12. In this embodiment, the lens plate 6 is cancelled, and the specific electromagnetic wave passing mechanism 4 is installed at the position of the lens plate 6, realizing the dual functions of screening electromagnetic waves and sealing the furnace tube assembly 1.

[0045] Embodiment 6

[0046] This embodiment provides an imaging method of an ash fusibility tester, comprising the following steps:

[0047] S1: The electromagnetic wave generating mechanism 2 emits electromagnetic waves;

[0048] S2: driving the ash cone support assembly 5 to rotate;

[0049] S3: the electromagnetic wave receiving mechanism 3 obtains the electromagnetic wave emitted by the electromagnetic wave generating mechanism 2 through the specific electromagnetic wave passing mechanism 4;

[0050] S4: The electromagnetic wave receiving mechanism 3 decodes the received electromagnetic wave to obtain an image of the sample between the electromagnetic wave generating mechanism 2 and the electromagnetic wave receiving mechanism 3 .

[0051] Through the imaging method in this embodiment, the specific electromagnetic wave passing mechanism 4 can effectively filter out the electromagnetic waves emitted by the sample and the surrounding ash cone support assembly 5 and furnace tube assembly 1, and only receive the electromagnetic waves of a specific wavelength emitted by the electromagnetic wave generating mechanism 2. When the sample placed on the ash cone support assembly 5 rotates between the electromagnetic wave generating mechanism 2 and the electromagnetic wave receiving mechanism 3, the sample will block part of the electromagnetic waves emitted by the electromagnetic wave generating mechanism 2. Therefore, the image of the sample can be obtained by analyzing the electromagnetic waves. The electromagnetic wave recognition accuracy is high, which improves the image recognition accuracy.
