Abstract
Description
Technical Field
[0001] This utility model relates to the field of disc scraper dryer technology, specifically to a testing device for disc scraper dryer components. Background Technology
[0002] A disc scraper dryer is a type of contact dryer used to extract dry substances from liquids containing solid particles, such as solutions and suspensions. The liquid to be dried is sprayed onto a steam-heated disc through a pump and multiple nozzles. The liquid evaporates on the heated disc surface. After the remaining dry substance rotates once, a scraper on the disc scrapes it off the disc surface, and then exhaust gas containing water vapor is discharged. Thus, the core components of this dryer are the scraper and the disc for removing the material.
[0003] Since the dryer's operating principle involves a scraper continuously scraping material off a rotating disc, ensuring the efficiency and stability of material scraping requires a flat surface on the disc. This allows the scraper to closely adhere to the disc surface for material removal. However, the flatness of the disc is typically checked manually using measuring instruments such as dial indicators, which is inefficient and lacks precision.
[0004] Therefore, it is necessary to design a practical and automated detection device for disc scraper dryer components. Utility Model Content
[0005] The purpose of this invention is to provide a detection device for disc scraper dryer components to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a testing device for a disc scraper dryer assembly, comprising a placement platform, a movable guide rail frame at the upper end of the placement platform, a driving part, a dial indicator and a support part on the upper side of the guide rail frame, the support part for supporting the central axis of the disc body, the driving part for driving the disc body to rotate, and the dial indicator for conforming to the surface of the disc body to detect flatness.
[0007] According to the above technical solution, a vertical plate frame is also provided at one end of the placement platform. A pair of wheels are rotatably connected to one side of the vertical plate frame, and the pair of wheels support the other end of the disc body. A central plate is rotatably connected to the middle side of the vertical plate frame, and the central plate coincides with the axis of the disc body.
[0008] According to the above technical solution, the driving unit includes a rubber sleeve, which is adapted to the size of the central axis of the disc body, and the rubber sleeve is driven to rotate by a motor.
[0009] According to the above technical solution, the lower end of the dial indicator is fixedly connected to a base, the lower end of the base is slidably fitted with a linear track frame, the lower end of the linear track frame is fixedly connected to a guide rail frame, the lower end of the base is fixedly connected to a connecting block, the connecting block passes through the linear track frame, the lower end of the connecting block is fixedly connected to a nut, and a threaded rod is rotatably connected between the guide rail frames, the threaded rod passes through the nut and is threadedly connected to it.
[0010] According to the above technical solution, the support part includes a support rod, which is fixed to the upper end of the guide rail frame, and a pair of support wheels are fixedly connected to the upper end of the support rod.
[0011] According to the above technical solution, the lower side of the guide rail frame is slidably fitted with a guide frame, the guide frame is disposed on the upper side of the placement platform, and the guide rail frame is driven by a linear drive assembly.
[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0013] A support unit is provided to stabilize the disc body. Then, the guide rail moves the drive unit and dial indicator. When the central axis of the disc body enters the drive range of the drive unit, the dial indicator probe also contacts the surface of the disc body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-5 The present invention provides a technical solution: a testing device for a disc scraper dryer assembly, comprising a placement platform 1, a movable guide rail 14 at the upper end of the placement platform 1, a driving part, a dial indicator 2 and a support part on the upper side of the guide rail 14, the support part being used to support the central axis of the disc body 6, the driving part being used to drive the disc body 6 to rotate, and the dial indicator 2 being used to conform to the surface of the disc body 6 for flatness testing.
[0022] Preferably, when testing is required, the disc body 6 is manually placed on the placement platform 1, where a support is provided to stabilize the disc body 6. Then, the guide rail 14 drives the drive unit and dial indicator 2 to move. When the central shaft end of the disc body 6 enters the driving range of the drive unit, the probe of the dial indicator 2 also contacts the surface of the disc body 6. Then, the drive unit rotates the disc body 6, allowing the dial indicator 2 to test one circumference of the disc body 6. By manually observing whether the circular runout is within the acceptable range, the flatness of the disc body 6 can be determined. Compared with manual testing, this device has higher accuracy and improves convenience and work efficiency.
[0023] A vertical plate frame 3 is also provided at one end of the placement platform 1. A pair of wheels 4 are rotatably connected to one side of the vertical plate frame 3. The pair of wheels 4 support the other end of the disc body 6. A central plate 5 is rotatably connected to the middle side of the vertical plate frame 3. The central plate 5 coincides with the axis of the disc body 6.
[0024] Preferably, a pair of discs 4 are provided on the other side of the disc body 6 for support, so as to cooperate with the support part to align the position of the disc body 6. A center disc 5 is provided to contact the center of the other side of the disc body 6. When the drive part drives the disc body 6 to rotate, the center disc 5 rotates synchronously, ensuring the position of the axis of the disc body 6 while preventing the surface of the disc body 6 near the vertical plate frame 3 from being rubbed.
[0025] The drive unit includes a rubber sleeve 7, which is adapted to the size of the central axis of the disc body 6, and the rubber sleeve 7 is driven to rotate by a motor 8.
[0026] Preferably, the rubber sleeve 7 is fitted onto the central shaft of the disc body 6, and the rubber sleeve 7 is driven to rotate by the motor 8. Through compression and friction, the disc body 6 can be rotated for testing.
[0027] The lower end of dial indicator 2 is fixedly connected to a base, and the lower end of the base is slidably fitted with a linear track frame 11. The lower end of the linear track frame 11 is fixedly connected to a guide rail frame 14. The lower end of the base is fixedly connected to a connecting block 12, which passes through the linear track frame 11. The lower end of the connecting block 12 is fixedly connected to a nut 13. A threaded rod 15 is rotatably connected between the guide rail frames 14 and the nut 13, which is threadedly connected to it.
[0028] Preferably, the dial indicator 2 is positioned below the central axis of the disc body 6. The nut 13, connecting block 12, and dial indicator 2 are displaced by rotating the threaded rod 15. The dial indicator 2 moves along the linear track frame 11, thereby enabling its probe to detect the surface flatness of the disc body 6. Combined with the rotation of the disc body 6 itself, a comprehensive inspection of its surface is achieved to ensure flatness.
[0029] The support includes a support rod 16, which is fixed to the upper end of the guide rail frame 14. A pair of support wheels 17 are fixedly connected to the upper end of the support rod 16.
[0030] Preferably, a pair of support wheels 17 are provided to support the central axis of the disc body 6, so that when the disc body 6 rotates, the support wheels 17 rotate with it, reducing friction on the surface of the central axis.
[0031] Optionally, a cylindrical cavity 10 is provided at one upper end of the guide rail frame 14, and a worm gear 18 is provided at the drive end of the motor 8. A worm wheel 19 is meshed with the lower side of the worm gear 18. A central rod 20 is fixedly connected through the center of the worm wheel 19. Both ends of the central rod 20 are rotatably connected to the cylindrical cavity 10. A sprocket 21 is fixedly connected to one end of the central rod 20. A sprocket 22 is chain-driven connected to one side of the sprocket 21. A detachable outer shell is provided on the outer side of the sprocket 21 and the sprocket 22. One end of the sprocket 22 is fixedly connected to the threaded rod 15, and one end of the worm gear 18 is fixedly connected to the rubber sleeve 7. When the test begins, the motor 8 drives the worm gear 18 to rotate. While driving the rubber sleeve 7 to rotate, it also drives the worm wheel 19 to rotate through a meshing connection. Then, through chain transmission, it drives the threaded rod 15 to rotate, thereby driving the dial indicator 2 to make horizontal displacement. In other words, by rotating the motor 8, the disc body 6 can be rotated at the same time, and the dial indicator 2 can be driven to make horizontal displacement. The test can be completed in one go, which is highly practical. Moreover, due to the large transmission ratio of the worm gear mechanism, the faster rotation speed of the disc body 6 is converted into the slower displacement of the dial indicator 2, which matches the movement speed of the two during actual testing.
[0032] The lower side of the guide rail frame 14 is slidably engaged with the guide frame 9, which is located on the upper side of the placement platform 1. The guide rail frame 14 is driven by a linear drive assembly.
[0033] Preferably, the linear drive assembly includes, but is not limited to, a lead screw mechanism, a gear and rack mechanism, or a cylinder. Since the above mechanisms are all common existing technologies in the field, they will not be described in detail here.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
