Description

TECHNICAL FIELD

[0001] The present application relates to the field of furnace mouth measurement of carbonization furnace, and particularly to a portable distance measuring device. BACKGROUND

[0002] In the production process of carbon fiber, a carbonization process is needed. The carbonization process of carbon fiber is to convert the heat-resistant ladder-shaped structure of pre-oxidized yarn into a turbostratic graphite structure of carbon fiber.

[0003] In this process, the internal structure of the fiber gradually changes from the relatively ordered ladder-shaped polymer structure of pre-oxidized yarn to the turbostratic graphite structure in carbon fiber. The turbostratic graphite structure refers to the fact that the carbon atom layers in the carbon fiber have a certain degree of stacking, but compared with the ideal graphite structure, the stacking is relatively disordered. This structure makes the carbon fiber have both high strength and modulus and also maintain a certain flexibility.

[0004] The carbonization process of the fiber needs to use a carbonization furnace. The furnace mouth opening of the carbonization furnace is an important technical parameter. The furnace mouth opening needs to ensure that the carbon fiber can enter without causing wear and tear, and also needs to prevent a large amount of air from entering to affect the carbonization process. Therefore, it is necessary to control the furnace mouth opening within a certain range. However, due to the high carbonization temperature, manually measuring the furnace mouth opening using a vernier caliper not only has the risk of being scalded by hot air, but also leads to inaccurate measurement data.

[0038] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to all alternative modifications and embodiments as would be apparent to those of ordinary skill in the art. It is to be understood that other aspects of the application can be utilized and that the exemplary embodiments are presented for illustrative purposes only. The description of the exemplary embodiments is not intended to be complete or exhaustive, but rather is presented to provide an understanding of the application.

[0039] The carbonization process is required in the production of carbon fiber, and the carbonization process of carbon fiber is to convert the heat-resistant ladder structure of pre-oxidized yarn into a turbostratic graphite structure of carbon fiber. In this process, the internal structure gradually changes from the relatively ordered ladder polymer structure of pre-oxidized yarn to the turbostratic graphite structure in carbon fiber. The turbostratic graphite structure refers to the fact that the carbon atom layers in the carbon fiber have a certain degree of stacking, but compared with the ideal graphite structure, the stacking is relatively disordered. This structure makes the carbon fiber have both high strength and modulus and also maintain a certain flexibility.

[0040] The opening degree of the furnace mouth of the carbonization furnace is an important technical parameter. The opening degree of the furnace mouth needs to ensure that the carbon fiber can enter without being abraded, and also needs to prevent a large amount of air from entering to affect the carbonization process. Therefore, it is necessary to control the opening degree of the furnace mouth within a certain range. However, due to the high carbonization temperature, the worker needs to be located at the furnace mouth when using a vernier caliper to measure the opening degree of the furnace mouth. The hot gas at the furnace mouth not only poses a risk of scalding the worker, but also makes it difficult to accurately measure.

[0041] To solve the above technical problems, the application provides a portable distance measuring device. The hand-held part is convenient for the worker to hold. The first end of the hand-held part is provided with a first clamping part, and the length direction of the first clamping part and the length direction of the hand-held part have a preset angle, so that the hand-held part does not correspond to the furnace mouth during measurement. The first end of the moving part is slidingly installed on the hand-held part. The sliding direction of the moving part is consistent with the length direction of the hand-held part. The second end of the moving part is located outside the first end of the hand-held part and is connected with the second clamping part. The first clamping part and the second clamping part are arranged in parallel. The measuring part is arranged on the hand-held part and is used to read the distance between the first clamping part and the second clamping part. During measurement, the second clamping part is moved by moving the moving part, so that the first clamping part and the second clamping part are clamped at the position with the longest interval distance of the furnace mouth, and the distance value is read. During adjustment, the worker does not need to be located at the furnace mouth, and the distance between the second clamping part and the first clamping part can be adjusted by adjusting the moving part, so as to avoid the worker being scalded by the hot gas and improve the safety. In addition, due to the arrangement of the handle, the worker can accurately adjust during the adjustment process.

[0042] According to an exemplary embodiment of the present application, as Figs. 1-3As shown, the embodiment provides a portable device for measuring distance. The device comprises a handheld part 1, which is arranged in a shell structure, so as to reduce the weight of the device to some extent, and the inside of the shell structure can also be used as a containing space for accommodating other structures. The handheld part 1 can be held by the staff, and the distance of the furnace opening is measured by holding the handheld part 1, so as to improve portability and safety, and the staff can measure without being close to the furnace opening, so as to avoid being scalded.

[0043] The first end of the first clamping part 2 is arranged at the first end of the handheld part 1, and the length direction of the first clamping part 2 and the length direction of the handheld part 1 have a preset angle. The preset angle is arranged to avoid the handheld part 1 facing the furnace opening during measurement, so that the staff can be away from the hot gas of the furnace opening and avoid being scalded.

[0044] The first end of the moving part 3 is slidingly installed on the handheld part 1, and the second end of the moving part 3 is located outside the first end of the handheld part 1. By adjusting the first end of the moving part 3, the second end of the moving part 3 can be made to approach or move away from the handheld part 1. Since the first clamping part 2 is arranged on the handheld part 1, by adjusting the first end of the moving part 3, the second end of the moving part 3 can also be made to approach or move away from the first clamping part 2. The second clamping part 4 is connected to the second end of the moving part 3, and the position of the second clamping part 4 can be adjusted by adjusting the moving part 3, so that the second clamping part 4 approaches or moves away from the first clamping part 2. The first clamping part 2 and the second clamping part 4 are arranged in parallel, so as to facilitate the measurement of the distance between the first clamping part 2 and the second clamping part 4, that is, the distance moved by the moving part 3.

[0045] The measuring part 5 is arranged on the handheld part 1 and is used for measuring the distance between the first clamping part 2 and the second clamping part 4. During measurement, the first clamping part 2 and the second clamping part 4 are arranged at the position with the longest interval distance of the furnace opening, so as to truly reflect the maximum size of the furnace opening and ensure the accuracy and reliability of the measurement. The distance between the first clamping part 2 and the second clamping part 4 is the distance moved by the moving part 3, that is, the opening degree of the furnace opening.

[0046] In some embodiments, a sliding groove 11 is arranged on the side wall of the handheld part 1, the sliding groove 11 communicates the inside and outside of the handheld part 1, and the length direction of the sliding groove 11 is the same as the sliding direction of the moving part 3. As shown in the figure, Figs. 2-3As shown, the moving part 3 comprises a connecting piece 31 and a sliding piece 32, the connecting piece 31 is a rod or a strip, the first end of the connecting piece 31 is located inside the handheld part 1, and the second end of the connecting piece 31 extends outside the second end of the handheld part 1, the sliding piece 32 is a block, one end of the sliding piece 32 is connected with the first end of the connecting piece 31 and located inside the handheld part 1, and the other end of the sliding piece 32 extends outside the handheld part 1 and is located outside the handheld part 1. The sliding piece 32 is sleeved on the connecting piece 31 and can slide along the connecting piece 31. The sliding piece 32 extends outside the handheld part 1 to facilitate the movement of the staff, and the setting of the sliding groove 11 provides accurate guidance for the sliding of the sliding piece 32, so that the sliding piece 32 can only slide in the direction of the sliding groove 11, effectively limiting the movement of the sliding piece 32 in other directions, preventing unnecessary shaking or deviation, and thus ensuring the accuracy of the reading.

[0047] When the sliding piece 32 is located at the end of the sliding groove 11 away from the first clamping part 2, the part of the connecting piece 31 located inside the handheld part 1 is the most, the part of the connecting piece 31 extending outside the handheld part 1 is the least, the distance between the first clamping part 2 and the second clamping part 4 is the smallest, and the value read by the measuring part 5 is the smallest; when the sliding piece 32 is located at the end of the sliding groove 11 close to the first clamping part 2, the part of the connecting piece 31 located inside the handheld part 1 is the least, the part of the connecting piece 31 extending outside the handheld part 1 is the most, the distance between the first clamping part 2 and the second clamping part 4 is the largest, and the value read by the measuring part 5 is the largest.

[0048] In some embodiments, as shown in Figs. 2-3 As shown, the sliding piece 32 comprises a first part 321 and a second part 322, both of which are blocks, the first part 321 is arranged across the sliding groove 11, the first end of the first part 321 is located inside the handheld part 1 and connected with the first end of the connecting piece 31, and the second end of the first part 321 extends outside the sliding groove 11 and is connected with the second part 322, the second part 322 is located outside the handheld part 1, and the two sides of the second part 322 are located outside the width of the sliding groove 11, that is, the cross section of the second part 322 is larger than the width of the sliding groove 11. In this application, by sliding the second part 322, the second part 322 drives the first part 321 to slide along the sliding groove 11, the first part 321 drives the connecting piece 31 to slide, and the connecting piece 31 drives the second clamping part 4 to slide, thereby measuring the furnace opening.

[0049] In some embodiments, as shown in Figs. 1-3 As shown, the outer surface of the second part 322 is provided with an anti-skid layer, which can be a silica gel layer, or a plurality of convex points can be arranged on the surface of the second part 322. The anti-skid layer facilitates the movement of the second part 322 and avoids slipping during movement.

[0050] In some embodiments, such as Figs. 2-3 As shown, a portable distance measuring device also includes a slide 6, which fills the interior of the handheld part 1. A channel 61 is provided on the slide 6, which in this application is a groove formed by the inward indentation of the slide 6. The channel 61 is located near the slide groove 11, and its length direction is the same as that of the connector 31. The portion of the connector 31 located inside the handheld part 1 is situated at the channel 61 and slides along the channel 61. The sidewall of the connector 31 facing the slide groove 11 contacts and slides against the inner side of the sidewall of the handheld part 1, while the other three sidewalls of the connector 31 contact and slide against the three sidewalls of the channel 61. The slide 6 facilitates the stability of the connector 31, preventing it from shaking and increasing the accuracy of the measurement.

[0051] In some embodiments, both the surfaces of the first card portion 2 and the second card portion 4 are coated with a high-temperature resistant coating, or the high-temperature resistant coating may be applied only to the surface of the first card portion 2 or only to the surface of the second card portion 4. The high-temperature resistant coating may be one of a ceramic coating, a silicone resin coating, or a cobalt-based alloy coating. The high-temperature resistant coating protects the first card portion 2 and the second card portion 4 from high-temperature damage and resists chemical corrosion, thereby improving the service life of the device.

[0052] In some embodiments, the measuring unit 5 includes a display screen and a sensor. The sensor is disposed on the connector 31 and is used to detect the distance between the first measuring plate and the second measuring plate, that is, the distance the connector 31 moves. The sensor can be a capacitive grating sensor, wherein the main grating of the capacitive grating sensor is disposed inside the handheld part 1, and the secondary grating of the capacitive grating sensor is disposed on the connector 31. When the connector 31 moves, the relative position between the main grating and the secondary grating changes, causing the capacitance value between them to change. By measuring the change in capacitance value, and converting it into a digital signal through a conversion circuit, and displaying it on the display screen, it is the distance the connector 31 moves, that is, the distance the second card part 4 moves. By measuring the distance the second card part 4 moves, the distance between the first card part 2 and the second card part 4 is obtained, which is the opening degree of the furnace mouth.

[0053] In some embodiments, during measurement, the preset angle between the first card portion 2 and the handheld portion 1 is 85° to 95°, and the second card portion 4 is arranged parallel to the first card portion 2. Therefore, the included angle between the second card portion 4 and the connecting member 31 is the same as the preset angle, which is 85° to 95°. Preferably, the preset angle between the first card portion 2 and the handheld portion 1 is 90°, and the included angle between the second card portion 4 and the connecting member 31 is also 90°. Setting the angle between the first card portion 2 and the handheld portion 1 to 90° makes the measurement process more convenient and ensures the stability of the device in this application during the measurement process.

[0054] In some embodiments, the first card part 2 is arranged at the second end of the handheld part 1 through the first hinging structure 7, and the second card part 4 is arranged at the second end of the connecting piece 31 through the second hinging structure 8, or only the first card part 2 is arranged at the second end of the handheld part 1 through the first hinging structure 7, or only the second card part 4 is arranged at the second end of the handheld part 1 through the second hinging structure 8. The first hinging structure 7 is arranged to facilitate adjustment of the preset angle between the first card part 2 and the handheld part 1, and the second hinging structure 8 is arranged to facilitate adjustment of the included angle between the second card part 4 and the connecting piece 31. The first hinging structure 7 is a hinge, and the friction of the hinge is relatively large, so a relatively large driving force is required to rotate the first card part 2 relative to the handheld part 1, and the first card part 2 is fixed when rotated to a specified position. The second hinging structure 8 can be the same as the first hinging structure 7. In other embodiments, the second end of the connecting piece 31 is provided with a connecting plate 9, and the second card part 4 is hinged through the connecting plate 9. One end of the connecting plate 9 is connected to the second end of the connecting piece 31, and the other end of the connecting plate 9 is provided with the second hinging structure 8, and the second card part 4 is arranged on the connecting plate 9 through the second hinging structure 8.

[0055] In some embodiments, the surface of the handheld part 1 away from the display screen is recessed inward to form a recess 12, and the first card part 2 is arranged in the recess 12 through the first hinging structure 7. In the present application, the recess 12 can accommodate the first card part 2 and the second card part 4 side by side. When accommodated, the first card part 2 and the second card part 4 are arranged side by side from the inside to the outside of the recess 12, so that the device can be conveniently stored when not in use.
