Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a crucible cleaning device. Background Technology

[0002] Crucibles are an essential component of chemical instruments. They serve as containers for melting and refining molten metals, as well as for solid-liquid heating and reactions, and are fundamental to ensuring the smooth progress of chemical reactions. Quartz crucibles, with their advantages of high purity, strong temperature resistance, large size and high precision, good heat retention, energy saving, and stable quality, are increasingly widely used. The inspection of quartz crucibles is a crucial step, and the inspection process is evolving towards on-site testing. Currently, after experiments such as evaporation, waste products easily adhere to the inner walls and bottom of quartz crucibles, requiring thorough cleaning before the next operation.

[0003] Chinese utility model CN209953439U discloses a cleaning device for platinum crucibles. The principle is to place the platinum crucible on a worktable and rotate the screw to drive the threaded rod to rotate. As the threaded rod rotates, it drives the nut to move, causing the nut to bring the clamping plate closer, thereby clamping the platinum crucible. Finally, the platinum crucible is cleaned using a brush plate.

[0004] However, existing devices only have two clamping plates close together to hold and fix the platinum crucible during use. Since platinum crucibles are generally circular, they are prone to detaching from the inside of the clamping plates after being impacted, so the clamping is not firm enough. Therefore, a platinum crucible cleaning device with more firm clamping was designed to address the above-mentioned problems. Utility Model Content

[0031] Crucibles are an essential component of chemical instruments. They serve as containers for melting and refining molten metals, as well as for solid-liquid heating and reactions, and are fundamental to ensuring the smooth progress of chemical reactions. Quartz crucibles, with their advantages of high purity, strong temperature resistance, large size and high precision, good heat retention, energy saving, and stable quality, are increasingly widely used. The inspection of quartz crucibles is a crucial step, and the inspection process is evolving towards on-site testing. Currently, after experiments such as evaporation, waste products easily adhere to the inner walls and bottom of quartz crucibles, requiring thorough cleaning before the next operation.

[0032] In related technologies, a platinum crucible is placed on a worktable, and rotating a knob drives a threaded rod to rotate. Simultaneously, the rotating rod moves a nut, causing it to bring clamping plates closer together to hold the crucible. Finally, a brush plate cleans the crucible. However, existing devices only have two clamping plates close together to hold and secure the crucible. Since platinum crucibles are generally circular, they are prone to detaching from the inside of the clamping plates after being clamped, resulting in insufficient clamping strength.

[0033] To address some of the problems in the related technologies, this application provides a crucible cleaning device. When a platinum crucible needs to be cleaned, the platinum crucible is first placed on the worktable 11. Then, the motor 21 is connected to an external power source to drive the threaded rod 22 to rotate. During rotation, the internal threaded block 23 moves downward, which in turn drives the connecting rod 24 to rotate. At the same time, the top of the connecting rod 24 drives the slider 26 to slide inside the groove 25, causing the protrusion 27 to converge. The protrusion 27 can clamp the platinum crucible, fixing it to the top of the worktable 11. Finally, the drive module 13 drives the brush rod 14 to rotate and clean the inner wall of the platinum crucible.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figures 1-4 This application provides a crucible cleaning device, including: a workbench 11 with a support 12 on its top; a drive module 13 on the top of the support 12; a brush rod 14 on the bottom output shaft of the drive module 13; a clamping assembly 2 on the workbench 11, the clamping assembly 2 including: a motor 21 on the bottom of the workbench 11; a threaded rod 22 on the bottom output shaft of the motor 21; an internal threaded block 23 penetrated by the threaded rod 22 and threadedly connected to the threaded rod 22; a connecting rod 24 on one side of the internal threaded block 23 and rotatably connected to the internal threaded block 23; a slide groove 25 on the top of the workbench 11; a slider 26 slidably disposed inside the slide groove 25 and rotatably connected to the top end of the connecting rod 24; and a protruding rod 27 on the top of the slider 26.

[0036] When cleaning the platinum crucible, first place the platinum crucible on the workbench 11, then connect the motor 21 to the external power supply to drive the threaded rod 22 to rotate. When rotating, it will drive the internal threaded block 23 to move downward. During the downward movement, it will drive the connecting rod 24 to rotate. At the same time, the top of the connecting rod 24 will drive the slider 26 to slide inside the groove 25, causing the protrusion 27 to gather. The protrusion 27 can clamp the platinum crucible and fix it on the top of the workbench 11. Finally, the drive module 13 drives the brush rod 14 to rotate to clean the inner wall of the platinum crucible.

[0037] In some embodiments, four sets of the connecting rod 24, the slide groove 25, the slider 26, and the protruding rod 27 are provided.

[0038] When in use, the four-group design can hold and fix the platinum crucible in four directions, making the fixation more stable and the platinum crucible less likely to fall off.

[0039] In some embodiments, the clamping assembly 2 further includes a rubber sleeve 28 disposed on the outer side wall of the protruding rod 27.

[0040] The design of the rubber sleeve 28 allows the rubber material to better protect the outer wall of the platinum crucible when it is being secured.

[0041] In some embodiments, the clamping assembly 2 further includes a baffle 29 disposed at the bottom of the threaded rod 22.

[0042] The design of the baffle 29 during use ensures that the internal thread block 23 will not disengage from the thread rod 22 when the thread rod 22 rotates.

[0043] In some embodiments, the brush handle 14 is U-shaped.

[0044] When in use, the 14U-shaped design of the brush handle better conforms to the inner wall of the platinum crucible, resulting in a better cleaning effect.

[0045] In some embodiments, the drive module 13 is provided with a cleaning component 3, the cleaning component 3 including: a rectangular rod 31 whose top end is inserted into the interior of the output shaft of the drive module 13 and whose bottom end is connected to the brush rod 14; a top plate 32 disposed on the top of the top plate 32; and a spring 33 disposed on the top of the top plate 32 and whose top end is connected to the inner sidewall of the output shaft of the drive module 13.

[0046] When placing the platinum crucible, the brush rod 14 can be pulled upwards to drive the rectangular rod 31 into the output shaft of the drive module 13, while simultaneously driving the top plate 32 to compress the spring 33. After the platinum crucible is placed, the brush rod spring 33 is released and pushes the top plate 32 back to make the brush rod 14 fit better against the inner wall of the platinum crucible.

[0047] In some embodiments, the cleaning assembly 3 further includes a brush plate 34 disposed at the top end of the brush rod 14.

[0048] When in use, the brush plate 34 is designed to clean the outer wall of the platinum crucible, improving the cleaning effect.

[0049] In some embodiments, the cleaning assembly 3 further includes: a bolt 35 with its bottom end penetrating through the brush plate 34 and inserted into the interior of the brush rod 14, and threadedly connected to the brush rod 14.

[0050] When in use, the design of bolt 35 allows the brush plate 34 to be installed on the top of the brush rod 14, or it can be disassembled for use as needed.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.
