Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis technology, and in particular to a sample crushing device. Background Technology

[0002] In the electrolytic aluminum production process, it is necessary to analyze and test the electrolyte composition in each electrolytic cell. The analysis process involves removing and crushing the electrolyte. In the existing technology, the crushing device uses a hydraulic device. The worker puts the electrolyte under the hydraulic hammer and drives the hydraulic hammer to move downward to crush the electrolyte. This method can only crush a single electrolyte at a time, and after crushing, the worker needs to clean the workbench under the hydraulic hammer to prevent different electrolyte fragments from mixing during the crushing process, which would cause errors in the test results. This method has a long crushing time, affects production efficiency, and increases production costs. Utility Model Content

[0003] In view of the technical problems existing in the background art, the purpose of this utility model is to provide a sample crushing device that crushes multiple electrolytes at the same time, making the crushing process efficient and fast, and also making the test results more accurate.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A sample crushing device includes a crushing cup for storing samples, a stop assembly, and a crushing structure. The crushing structure includes a rotating shaft, a protruding rod, and several sets of crushing components. The protruding rod is disposed on one side of the rotating shaft, and the crushing components are disposed on the other side of the rotating shaft. Each crushing component includes a crushing arm and a crushing hammer disposed at one end of the crushing arm. The stop assembly includes several rolling stops aligned with the protruding rod. The crushing cup is disposed below the crushing hammer. When the rolling stops rotate and abut against the protruding rod, they separate, causing the crushing hammer to rotate and fall, thereby allowing the crushing hammer to extend into the crushing cup to crush the sample.

[0006] Preferably, the crushing structure also includes several support plates, and the rotating shaft is rotatably disposed between the support plates.

[0007] Preferably, the shift lever assembly also includes a drive unit and a connecting shaft, wherein the drive unit is disposed at one end of the connecting shaft, and a plurality of rolling shift levers are evenly distributed on one side of the connecting shaft.

[0008] Preferably, the system also includes a detection component, which includes a support rod and a first detection element. The detection component is disposed on one side of the broken structure, and the first detection element is disposed on the gear lever.

[0009] Preferably, the detection assembly further includes a second detection element, which is disposed on the support rod, and the first detection element is disposed at the lower end of the second detection element. When the breaker hammer extends into the breaker cup, the breaker arm and the first detection element are aligned.

[0010] Preferably, the structure also includes a lifting component, which is disposed at the lower end of the crushing structure and located near the breaker hammer.

[0011] Preferably, the lifting assembly includes a top rod, a lead screw assembly, and a driver, wherein the lead screw assembly and the driver are connected, and the driver drives the lead screw assembly to rise or fall, and the top rod and the lead screw assembly are connected.

[0012] Preferably, the lead screw assembly includes a lead screw and a lead screw nut, the lead screw nut and the lead screw being configured to cooperate, the lead screw being connected to a driver, and the push rod being connected to the lead screw nut.

[0013] This utility model has the following advantages and beneficial effects:

[0014] In this invention, one rolling stop corresponds to one convex rod. When one rolling stop contacts the convex rod, the other rolling stops do not contact the convex rod. When the stop assembly moves, one set of crushing components works while the other crushing components do not work. Multiple sets of crushing components achieve intermittent movement, which can greatly reduce dust release. This not only protects the workshop environment but also greatly protects the health of workers. Multiple breaker hammers are provided, which can crush multiple samples. After crushing, the crushing cup can be directly removed and replaced with a new crushing cup, which greatly increases the crushing efficiency and reduces the overall construction time.

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Example

[0022] like Figures 1-3 As shown, a sample crushing device includes a crushing cup 1 for storing samples, a detection component 5, a lifting component 4, a stop component 3, and a crushing structure A. The crushing structure A includes a rotating shaft 24, several support plates 21, protruding rods 25, and several sets of crushing components 2. The support plates 21 are supported on the ground. The rotating shaft 24 is rotatably disposed between the support plates 21. The protruding rods 25 are disposed on one side of the rotating shaft 24, and the crushing components 2 are disposed on the other side of the rotating shaft 24. The crushing components 2 include crushing arms 22 and crushing hammers 23 disposed at one end of the crushing arms 22. The crushing arms 22 are disposed on one side of the rotating shaft 24. One protruding rod 25 corresponds to multiple crushing arms 22. When the rotating shaft 24 rotates, the rotating shaft 24 can drive multiple crushing arms 22 to move synchronously, thereby causing the crushing hammers 23 to rotate around the rotating shaft 24 as the axis.

[0023] like Figures 1-3As shown, the shift lever assembly 3 includes a drive unit 31, a connecting shaft 32, and several rolling shift levers 33. The drive unit 31 is located at one end of the connecting shaft 32, and the several rolling shift levers 33 are evenly distributed on one side of the connecting shaft 32. The several rolling shift levers 33 are not arranged on the same straight line, that is, the several rolling shift levers 33 are staggered at a fixed angle. The drive unit 31 is a rotary motor, or it can be other devices that can drive the connecting shaft 32 to rotate. The rolling shift levers 33 are aligned with the protruding rod 25, and the rolling shift levers 33 are short rod structures. When the rolling shift levers 33 and the protruding rod 25 continuously abut, the protruding rod 25 can rotate around the rotating shaft 24 as the axis, and at the same time, the crushing arm 22 also rotates synchronously. When the rolling shift levers 33 continuously rotate on the connecting shaft 32, they continuously abut and separate from the protruding rod 25. The crushing cup 1 is located below the crushing hammer 23. When the drive component 31 is working, the rolling stop 33 rotates and separates from the convex rod 25, causing the breaker hammer 23 to rotate, lift, and fall, thereby allowing the breaker hammer 23 to extend into the crushing cup 1 to crush the sample. One rolling stop 33 corresponds to one convex rod 25. When one rolling stop 33 is in contact with the convex rod 25, the other rolling stop 33 is not in contact with the convex rod 25. When the stop assembly 3 moves, one set of crushing components 2 is working while the other crushing components 2 are not working. Multiple sets of crushing components 2 achieve intermittent movement. Since the electrolyte will generate dust during the crushing process, if multiple sets of crushing components 2 work simultaneously, a large amount of dust will be released instantly, which will pollute the workshop environment and affect the health of workers. By adopting the intermittent method, the release of dust can be reduced to a great extent, which can not only protect the workshop environment but also protect the health of workers to a great extent.

[0024] like Figures 1-3As shown, the detection assembly 5 includes a support rod 51, a first detection element 52, and a second detection element 53. The detection assembly 5 is disposed on one side of the crushing structure A. The first detection element 52 is disposed on the support rod 51, and the second detection element 53 is disposed on the support rod 51. The first detection element 52 is disposed at the lower end of the second detection element 53. When the breaker hammer 23 extends into the crushing cup 1, the crushing arm 22 and the first detection element 52 are aligned. The lifting assembly 4 is disposed at the lower end of the crushing structure A and is located near the breaker hammer 23. The lifting assembly 4 includes a top rod 44, a lead screw assembly, and a driver 41. The lifting assembly 4 is a spiral lifting assembly as described in the prior art. The device includes a drive motor 41, which can be another device that can drive the lead screw 43 to rotate. The lead screw assembly is connected to the drive motor 41, and the drive motor 41 drives the lead screw assembly to rise or fall. The top rod 44 is connected to the lead screw assembly. The lead screw assembly includes the lead screw 43 and the lead screw nut 42. The lead screw nut 42 and the lead screw 43 are configured to cooperate. The lead screw 43 is connected to the drive motor 41, and the top rod 44 is connected to the lead screw nut 42. The lead screw assembly is provided with at least two sets. The top rod 44 is set between the lead screw nut 42, so that the top rod 44 can move stably on the lead screw 43, and at the same time, the crushing arm 22 can be stably raised or lowered.When the driver 41 rotates forward, it drives the lead screw 43 to rotate, causing the lead screw nut 42 to move towards the upper end of the lead screw 43. The lead screw nut 42 drives the top rod 44 to rise. Since the top rod 44 is located near the breaker hammer 23, when the top rod 44 rises, the breaker arm 22 rotates around the shaft 24, and the breaker arm 22 is lifted. When descending, the driver 41 can be reversed. When adding samples or collecting crushed samples, the breaker arm 22 needs to be lifted so that the breaker hammer 23 is away from the crushing cup 1. After setting the lifting component 4, when adding samples or collecting crushed samples, the lifting component 4 lifts the breaker arm 22, making it easier for workers to add or collect samples and preventing workers from being in danger when touching the crushing cup 1. The first detection element 52 is an infrared sensor, and the second detection element 53 is an infrared sensor. The first detection element 52 and the driver 41 are electrically connected, and the second detection element 53 and the driver 41 are electrically connected. The first detection element 52 is located near the breaker hammer 23. At the lower end of the second detection element 53, when the lifting component 4 lifts the crushing arm 22 and it reaches the second detection element 53, the second detection element 53 can receive the position information of the crushing arm 22 (the infrared light emitted by the second detection element 53 is blocked). At this time, the driver 41 stops working, and the worker can safely add or collect samples. After the worker leaves the crushing cup 1 position, the driver 41 is reversed, causing the lifting component 4 to descend, which in turn causes the crushing arm 22 to descend and leave the second detection element 53. When the crushing arm 22 reaches the position of the first detection element 52, the first detection element 52 can receive the position information of the crushing arm 22 (the infrared light emitted by the first detection element 52 is blocked). At this time, the driver 41 stops working. The first detection element 52 and the second detection element 53 will only work when the driver 41 is turned on. The first detection element 52 and the second detection element 53 will not work during the crushing process. This method can make the lifting position accurate and at the same time maximize the safety of the construction process.

[0025] Working principle: The driver 41 rotates forward, causing the lead screw 43 to rotate. The lead screw nut 42 drives the top rod 44 to rise, lifting several crushing arms 22. When the crushing arms 22 reach the second detection element 53, the driver 41 stops working. At this time, the sample is placed into the crushing cup 1, causing the driver 41 to rotate in reverse. The top rod 44 descends, driving the crushing arms 22 to descend. When the crushing arms 22 reach the position of the first detection element 52, the driver 41 stops working, causing the drive component 31 to work. The drive component 31 drives the connecting shaft 32 to rotate, and the connecting shaft 32 causes the rolling stop 33 to rotate synchronously. During the rotation of the rolling stop 33, it interacts with the convex rod... With continuous contact, the protruding rod 25 drives the rotating shaft 24 to rotate, which in turn causes the crushing arm 22 to rotate around the rotating shaft 24. The crushing hammer 23 leaves the crushing cup 1. During the rotation of the rolling stop 33, it contacts the protruding rod 25 and then separates. Due to its own weight, the crushing hammer 23 falls back into the crushing cup 1 to crush the sample. After the crushing cup containing the crushed sample is taken out, the sample is tested. At the same time, a new crushing cup 1 is placed under the crushing hammer 23, which can achieve simultaneous testing and crushing. After the test is completed, the crushing cup 1 is cleaned and the above operation is repeated, making the entire crushing process efficient and stable, while avoiding the mixing of electrolytes that may affect the test quality.

[0026] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
