Description

Technical Field

[0001] This utility model relates to the field of coal sample testing technology, and in particular to a cartridge cleaning mechanism and a coal sample testing device. Background Technology

[0002] The calorific value of coal is one of the important indicators for judging coal quality and is also a major pricing indicator in coal trading. The calorific value of coal needs to be measured using a calorimeter, and the oxygen bomb is an important piece of equipment in the calorimeter for measuring the calorific value of coal and other substances. When measuring the calorific value of a coal sample using a coal sample analysis device, a certain amount of water needs to be added to the bomb chamber before the coal sample is placed in the oxygen bomb, and then the combustion experiment is conducted. After the experiment, the water in the bomb chamber that has absorbed the sulfur components of the coal sample and generated SO2 and other waste gases during combustion needs to be poured out, and the bomb chamber needs to be rinsed with water. Finally, a certain amount of water needs to be added to the bomb chamber to prepare for the next experiment.

[0003] Traditional methods for cleaning oxygen bomb cartridges are mostly manual, which is not only inefficient but also prone to incomplete cleaning. To address this issue, existing technologies use cartridge cleaning mechanisms. However, after cleaning, the cartridges are typically dried by air drying or simple blowing. Such methods cannot guarantee that the cartridges are completely dry, leaving water stains on the inner wall, which can lead to electrode oxidation. Utility Model Content

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] like Figure 1As shown, this utility model provides a cartridge cleaning mechanism, including a frame 1, a clamping and flipping assembly 2, a cleaning assembly 3, and a drying assembly 4. The clamping and flipping assembly 2 is disposed on the frame 1 and is used to clamp and flip the cartridge 100. The cleaning assembly 3 is disposed on the frame 1 and can extend into the cartridge 100 to clean the inner wall of the cartridge 100. The drying assembly 4 includes a first driving component 41, an air outlet 42, and a hot air blower 43. The first driving component 41 is disposed on the frame 1 and is used to drive the air outlet 42 to move, and to extend the air outlet 42 into and out of the cartridge 100. The air outlet 42 has a first inner cavity, and the cavity wall of the first inner cavity is provided with a plurality of air outlet holes 421 spaced circumferentially. The output end of the hot air blower 43 extends into the first inner cavity to introduce hot air into the first inner cavity. In this embodiment, the air outlet 42 is connected to the hot air blower 43 through a hot air pipe 44. During operation, the inner wall of the cartridge 100 is cleaned by the cleaning component 3. After cleaning, the clamping and flipping component 2 flips the cartridge 100 so that the opening of the cartridge 100 faces the drying component 4. Then, the hot air generated by the hot air blower 43 is delivered to the first inner cavity of the air outlet 42 through the hot air pipe 44 and blown onto the inner wall of the cartridge 100 through multiple air outlet holes 421 to dry it.

[0037] By combining the clamping and flipping assembly 2, the cleaning assembly 3, and the drying assembly 4, efficient cleaning and drying of the bomb 100 can be achieved, resulting in a high degree of automation in the bomb cleaning mechanism. Furthermore, extending the air outlet 42 into the bomb 100 allows for precise drying of the internal components. Multiple air outlet holes 421 spaced circumferentially along the wall of the first inner cavity of the air outlet 42 increase the drying area, achieving comprehensive drying of the inner wall of the bomb 100. Introducing hot air into the first inner cavity via the hot air blower 43 further enhances the drying capacity. Therefore, this invention can thoroughly dry the bomb 100, achieving high efficiency in the drying operation, meeting the timeliness requirements for future use, without adversely affecting the performance of the oxygen bomb, and avoiding the impact of residual water on the amount of water needed to be added before subsequent experiments. It also removes residual coal particles from the inner wall of the bomb 100.

[0038] Optionally, the air outlet 42 is a cylindrical tube with multiple air outlet holes 421. At least two air outlet holes 421 are grouped into one group, with all air outlet holes 421 in each group spaced apart circumferentially along the cylindrical tube. Multiple groups of holes are also spaced apart along the height of the cylindrical tube. This arrangement allows hot air to reach all parts of the inner wall of the cartridge 100, increasing the radiation range of the hot air and further improving drying efficiency. Specifically, in this embodiment, all air outlet holes 421 in each group are equally spaced circumferentially along the cylindrical tube, and multiple groups of holes are equally spaced along the height of the cylindrical tube, allowing hot air to be more evenly distributed across all parts of the inner wall of the cartridge 100.

[0039] Optionally, in this embodiment, the cleaning component 3 and the drying component 4 are respectively arranged on opposite sides of the clamping and flipping component 2. This arrangement avoids interference between the cleaning component 3 and the drying component 4, has a reasonable structural design, saves space, and facilitates the installation of the cartridge cleaning mechanism on the mounting parts of the coal sample testing device.

[0040] Optionally, in this embodiment, the first driving component 41 includes a first driving member 411 and a first supporting member 412. The first driving member 411 is fixed to the frame 1, and its output end is disposed away from the clamping and flipping assembly 2, and is used to drive the first supporting member 412 to move linearly. Specifically, the first supporting member 412 is a horizontal plate with a simple structure and is easy to process. The air outlet 42 is fixed to the end of the first supporting member 412 near the clamping and flipping assembly 2. Driving the first supporting member 412 to move linearly by the first driving member 411 saves operation time. In addition, the air outlet 42 can be inserted into the cartridge 100 by retracting the output end of the first driving member 411, saving the space occupied by the first driving component 41. In other embodiments, the output end of the first driving member 411 can also be disposed facing the clamping and flipping assembly 2. Further, in this embodiment, the first driving member 411 is located on the lower side of the clamping and flipping assembly 2, and its output end is used to drive the first supporting member 412 to move linearly in the vertical direction. When the clamping and flipping assembly 2 flips the cartridge 100 so that the opening of the cartridge 100 faces downward, the first driving member 411 retracts to drive the first bearing member 412 to move vertically upward, thereby drying the inner wall of the cartridge 100. Furthermore, the first driving member 411 can be a cylinder, a hydraulic cylinder, or an electric actuator.

[0041] Optionally, the cleaning assembly 3 includes a second drive component 31, a water supply component, and a brush head 32. The second drive component 31 is fixed to the frame 1. The second drive component 31 is used to drive the brush head 32 to move and extend into the cartridge 100 and to drive the brush head 32 to rotate. The water supply component can add water into the cartridge 100. By moving the brush head 32 through the second drive component 31, the brush head 32 can be extended into the cartridge 100. While the water supply component adds water to the cartridge 100, the second drive component 31 drives the brush head 32 to rotate, which can achieve cleaning of the inner wall of the cartridge 100. With this configuration, a comprehensive cleaning of the inner wall of the cartridge 100 can be achieved, resulting in a better cleaning effect.

[0042] After the brush head 32 cleans the cartridge 100, coal sample particles will remain on the brush head 32. These residual coal sample particles can easily cause cross-contamination and contaminate the cartridge 100 to be cleaned subsequently. Optionally, the cartridge cleaning mechanism also includes a cleaning component 5, which includes an air pump 51, an air pipe 52, and an air nozzle 53. The air pump 51 is connected to the air pipe 52, and the air pipe 52 is connected to the air nozzle 53. The air nozzle 53 is used to blow air onto the brush head 32. In this embodiment, the brush head 32 includes a brush rod 321 and bristles 322 disposed on the brush rod 321. The air output by the air pump 51 is sent to the air nozzle 53 through the air pipe 52. The air nozzle 53 can be aimed at the base of the bristles 322 to blow away the residual coal sample particles on the brush rod 321 and the bristles 322. At the same time, it can also dry the brush rod 321 and the bristles 322, ensuring the cleanliness of the brush head 32 and extending its service life. When cleaning the brush head 32 using the cleaning component 5, a protective cover can be detachably installed around the brush head 32 to prevent coal sample particles from spilling onto other parts.

[0043] Optionally, the second driving component 31 includes a second driving member 311, a second supporting member 312, and a rotation driving member 313. The second driving member 311 is fixed to the frame 1, and its output end is positioned away from the clamping and flipping assembly 2, and is used to drive the second supporting member 312 to move linearly. Specifically, the second supporting member 312 is a horizontal plate with a simple structure and is easy to manufacture. The rotation driving member 313 is fixed to one end of the second supporting member 312 near the clamping and flipping assembly 2, and is used to drive the brush head 32 to rotate. With this configuration, the brush head 32 can be inserted into the cartridge 100 by retracting the second driving member 311, saving space occupied by the second driving member 31. In addition, driving the brush head 32 to move linearly by the second driving member 311 saves operation time. Further, in this embodiment, the second driving member 311 is located above the clamping and flipping assembly 2, and its output end is used to drive the second supporting member 312 to move linearly in the vertical direction. This design facilitates cleaning of the inner wall of the cartridge 100 while preventing water spillage. Optionally, the second drive component 311 can be a cylinder, hydraulic cylinder, or electric actuator, as long as it can drive the second support component 312 to move linearly.

[0044] Optionally, the brush head 32 includes a brush rod 321 and bristles 322. A rotation drive component 313 drives the brush rod 321 to rotate. The bristles 322 are disposed on the brush rod 321. The brush rod 321 has a second inner cavity. The cavity wall of the second inner cavity is provided with a plurality of liquid outlet holes 3211 spaced apart along the circumference. The water adding component can add water to the second inner cavity, thereby allowing water to enter the cartridge 100. With the above arrangement, when the brush rod 321 rotates, water can be sprayed on the inner wall of the cartridge 100, facilitating the cleaning of the inner wall. Further, the brush rod 321 has a hollow structure, and the top end of the brush rod 321 has an opening, while the bottom end of the brush rod 321 has a closed plate. Water from the water adding component enters the brush rod 321 through the opening at the top end of the brush rod 321. Optionally, the brush rod 321 passes through the second support member 312 and is rotatably connected to the second support member 312. The rotation drive component 313 includes a motor, a drive gear, and a driven gear. The motor is fixed to the second support member 312, the drive gear is fixed to the output end of the motor, and the driven gear meshes with the drive gear and is sleeved and fixed to the outer periphery of the brush rod 321. The motor drives the drive gear to rotate, which in turn drives the driven gear to rotate, thereby causing the brush rod 321 to rotate.

[0045] Alternatively, the bristles 322 are spirally wound around the brush handle 321. This arrangement results in less resistance when rotating the bristles 322.

[0046] Optionally, the clamping and flipping assembly 2 includes a third drive member 21 and a gripper component 22. The third drive member 21 is fixed to the frame 1 and drives the gripper component 22 to rotate. The gripper component 22 includes two grippers 221, which can move towards or away from each other. By clamping the cartridge 100 with the two grippers 221, it is possible to adapt to the clamping requirements of cartridges 100 of different specifications. Specifically, the third drive member 21 is a motor or a rotary cylinder. Specifically, the gripper component 22 is a finger cylinder.

[0047] Furthermore, both grippers 221 are equipped with cushioning pads. Specifically, the cushioning pads are rubber anti-slip pads, PVC anti-slip pads, PU anti-slip pads, or metal anti-slip pads, which can prevent scratches on the outer surface of the cartridge 100 caused by traditional rigid clamping.

[0048] Optionally, the clamping and flipping assembly 2 also includes an L-shaped plate 23, which is fixed to the output end of the third drive unit 21. The L-shaped plate 23 can be used to support the cartridge 100. When the gripper component 22 clamps the cartridge 100, the L-shaped plate 23 can support the cartridge 100, preventing it from falling. When the third drive unit 21 is activated, the L-shaped plate 23 and the gripper component 22 can rotate synchronously. When the opening of the cartridge 100 faces downward, the bearing end of the L-shaped plate 23 rotates closer to the brush head 32, which can avoid affecting the subsequent drying operation of the cartridge 100.

[0049] Optionally, a water collection tank 6 is provided at the lower end of the drying component 4 for collecting wastewater. The top of the water collection tank 6 has an opening, and the bottom of the water collection tank 6 has a drain hole 61. One end of a pipe is connected to the drain hole 61, and the pipe can discharge the wastewater. After the cleaning component 3 cleans the cartridge 100, the clamping and flipping component 2 flips the cartridge 100, which can pour the wastewater in the cartridge 100 into the water collection tank 6.

[0050] This utility model also provides a coal sample testing device, including an installation component and a cartridge cleaning mechanism, the cartridge cleaning mechanism being fixed to the installation component. This coal sample testing device can thoroughly dry the cartridge 100, and the drying operation is highly efficient. Furthermore, it has a high degree of automation.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
