Description

Technical Field

[0001] This utility model relates to the field of industrial analysis technology of samples, and in particular, to a crucible cleaning device. Background Technology

[0002] In automated coal testing systems, the combustion of coal in the calorimeter crucible produces various forms of coal ash or coke. Coal ash has relatively low adhesion and is easy to clean; however, coke tends to adhere to the crucible, especially at the bottom, and is difficult to remove. Some coke cannot be removed even with ultrasonic cleaning and requires the use of metal scrapers or wire brushes. However, during cleaning, dirt from inside the crucible easily adheres to the brush head, contaminating its surface and causing secondary contamination of the crucible for subsequent cleanings, potentially affecting subsequent tests.

[0003] Chinese Patent Publication No. CN207463761U discloses a high-efficiency organic evaporation crucible cleaning system, including a cleaning frame and a cleaning device and a control device mounted on the cleaning frame. The system also includes a cleaning liquid tank and a cleaning chamber connected to the cleaning frame. The upper end of the cleaning chamber has an inlet pipe, an outlet pipe, and a rotating shaft hole communicating with its inner cavity, and its lower end is open. The cleaning device includes a rotating mechanism and a brush head. The rotating mechanism passes through the rotating shaft hole and is detachably connected to the brush head located in the cleaning chamber. The cleaning liquid tank has an inlet chamber and an outlet chamber. The inlet pipe and the outlet pipe are respectively connected to the outlet chamber and the inlet chamber through a delivery pump. The control device is electrically connected to the delivery pump and the rotating mechanism respectively. One end of the crucible to be cleaned is pushed into the cleaning chamber through the opening of the cleaning chamber, and the inlet pipe and the brush head extend into the crucible to perform rotational brushing. This patent integrates an ultrasonic device into the brush head within the cleaning chamber. The brush head is inserted into the crucible to clean it, and a heating mechanism on the outside of the cleaning chamber heats and dries the cleaned crucible, achieving effective cleaning. However, this patent cannot clean both the inside and outside of the crucible simultaneously, resulting in incomplete cleaning, low efficiency, and poor results. Furthermore, the drying mechanism, integrated into the cleaning chamber, can easily cause residual wastewater to flow back to the crucible surface, leading to secondary contamination. Additionally, the heating method for drying the crucible requires a long drying time, resulting in low drying efficiency. Utility Model Content

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0036] like Figure 1 As shown, the crucible cleaning device of this embodiment includes a transfer mechanism 10 and a cleaning mechanism 20. The transfer mechanism 10 is used to clamp the crucible to be cleaned and transfer it, while the cleaning mechanism 20 is used to clean the crucible clamped by the transfer mechanism 10. The cleaning mechanism 20 includes a cleaning component 21 for brushing and ultrasonically cleaning the crucible, and a drying component 22 for hot air drying the brushed crucible. The cleaning component 21 and the drying component 22 are arranged along the horizontal movement direction of the transfer mechanism 10 and are located below the transfer mechanism 10. The crucible cleaning device also includes a mounting plate 60 located below the cleaning mechanism 20. The cleaning mechanism 20 is mounted on the mounting plate 60, and the transfer mechanism 10 is mounted on the mounting plate 60 and / or the cleaning mechanism 20. Therefore, the device can position and clamp the crucible through the transfer mechanism 10, and accurately transfer the clamped crucible to the cleaning mechanism 20 for cleaning. This ensures that the crucible is always precisely aligned with the cleaning position of the cleaning mechanism 20 during the cleaning process, improving cleaning quality. Furthermore, the coordinated operation of the transfer mechanism 10 and the cleaning mechanism 20 automates the entire crucible cleaning process, reducing manual intervention. By combining brushing and ultrasonic cleaning with the cleaning component 21 of the cleaning mechanism 20, stubborn stains on the crucible can be thoroughly removed, and both the interior and exterior of the crucible can be thoroughly cleaned simultaneously, significantly improving the cleaning effect and efficiency. In addition, by using the drying component 22 to dry the cleaned crucible with hot air, the drying time can be effectively shortened, improving drying efficiency. Moreover, the independent setup of the drying component 22 and the cleaning component 21 effectively avoids wastewater residue on the crucible, preventing secondary pollution and further improving the cleaning effect.

[0037] In use, the control transfer mechanism 10 clamps the crucible to be cleaned and moves it to a preset position in the cleaning component 21 of the cleaning mechanism 20. The cleaning component 21 is turned on to simultaneously brush the inside of the crucible and ultrasonically clean the outside. After cleaning, the control transfer mechanism 10 carries the crucible to a preset position in the drying component 22. The drying component 22 is turned on to dry the surface of the crucible with hot air. Then, the control transfer mechanism 10 removes the cleaned crucible from the drying component 22 for storage, thus completing the entire cleaning process.

[0038] like Figure 1As shown, the crucible cleaning device also includes a waste sample box 30. The waste sample box 30 is located on the side of the drying assembly 22 away from the cleaning assembly 21 along the horizontal movement direction of the transfer mechanism 10 and is mounted on the mounting plate 60. The waste sample box 30 is used to receive the waste sample poured out of the crucible. Specifically, the waste sample box 30 has an open top structure. After the transfer mechanism 10 picks up the crucible to be cleaned, it first moves above the waste sample box 30. By controlling the crucible to flip, the floating ash inside the crucible is poured into the waste sample box 30, thus achieving preliminary cleaning of the crucible.

[0039] like Figure 1 As shown, the crucible cleaning device also includes a storage mechanism 40. The storage mechanism 40 includes a storage tray rotatably disposed on one side of the cleaning mechanism 20 in a horizontal direction. The storage tray has multiple storage slots spaced apart circumferentially. The crucible is placed in the storage slot and moves to a preset position as the storage tray rotates for the transfer mechanism 10 to grip. In this embodiment, the gripping position of the storage tray is located on one side of the drying assembly 22, so that the transfer mechanism 10 can transfer the dried crucible to the storage tray for storage and use.

[0040] like Figure 1 and Figure 2 As shown, the transfer mechanism 10 includes a translation component 11 suspended above the cleaning mechanism 20, a lifting component 12 mounted on the translation component 11, and a clamping component 13 mounted on the lifting component 12. The translation component 11 drives the lifting component 12 to move horizontally, the lifting component 12 drives the clamping component 13 to move vertically, and the clamping component 13 clamps and flips the crucible. In this embodiment, the translation component 11 is located on the side of the cleaning mechanism 20 away from the storage mechanism 40 and is mounted on the cleaning mechanism 20. Preferably, the translation component 11 is mounted on the waste sample box 30. Optionally, the translation component 11 can also be mounted on the mounting plate 60. The lifting component 12 and the clamping component 13 are both located on the side of the translation component 11 close to the cleaning mechanism 20, and the clamping component 13 is correspondingly located above the cleaning mechanism 20 to ensure that the crucible clamped by the clamping component 13 can be transferred into the cleaning mechanism 20 for cleaning.

[0041] like Figure 1 and Figure 2As shown, the translation assembly 11 includes a first rotary drive 111, a lead screw mounted on the output end of the first rotary drive 111, a guide rail parallel to the lead screw, and a slider connected to the lead screw and the guide rail respectively. The slider is provided with a threaded hole threaded to the lead screw and a limiting structure for engaging the guide rail and guiding the slider to slide along the guide rail. Preferably, the translation assembly 11 further includes a cover plate disposed above the lead screw and the guide rail. The first rotary drive 111 is disposed at one end of the cover plate and mounted on the cover plate. A limiting block is provided at the end of the cover plate away from the first rotary drive 111. The limiting block is mounted on the end of the guide rail and movably cooperates with the lead screw to limit the slider. In this embodiment, the limiting block is disposed at the end near the waste sample box 30 and mounted on the mounting plate 60 and / or the waste sample box 30 through a column. Optionally, the cover plate, the first rotary drive 111, and / or the limiting block can also be connected and fixed to an external device. Preferably, the translation component 11 further includes a horizontal movement positioning sensor, which is mounted on the slider and electrically connected to the lifting component 12 to position the lifting component 12. This allows the slider to move the lifting component 12 and the clamping component 13 to the desired preset position, improving the efficiency and accuracy of the movement. Preferably, the first rotary drive component 111 is a rotary motor.

[0042] like Figure 1 and Figure 2 As shown, the lifting assembly 12 includes a second rotary drive 121, a gear 122, a sliding plate 123, and a connecting plate 124. Specifically, the sliding plate 123 is located between the translation assembly 11 and the second rotary drive 121 and is mounted on the slider. The connecting plate 124 is located on the side of the sliding plate 123 away from the translation assembly 11 and is mounted on the fixed end of the second rotary drive 121. The gear 122 is mounted on the output end of the second rotary drive 121. The sliding plate 123 has a vertically oriented receiving groove for accommodating the gear 122. A rack 1231 and a limiting rod are respectively provided vertically on both sides of the receiving groove. A sliding groove 1232 is provided vertically on the limiting rod. The rack 1231 meshes with the gear 122. The connecting plate 124 has a snap-fit ​​plate that is movably snapped into the sliding groove 1232 to guide and limit the lifting movement of the second rotary drive 121. Preferably, the lifting assembly 12 further includes a limiting plate and a lifting limit sensor mounted on the upper end of the sliding plate 123. The limiting plate is used to limit the gear 122 to prevent it from dislodging from the top of the sliding plate 123. The lifting limit sensor is electrically connected to the second rotary drive 121 to detect the lifting height of the second rotary drive 121. The lifting limit sensor can also be electrically connected to a controller to control the lifting height of the second rotary drive 121, so that the second rotary drive 121 can automatically adjust to a preset height, improving the level of automation. Preferably, the second rotary drive 121 is a rotary motor.

[0043] like Figure 1and Figure 2 As shown, the clamping assembly 13 includes a third rotary drive 131, a clamping drive 132, and a clamping frame 133. The fixed end of the third rotary drive 131 is mounted on the connecting plate 124, and the output end of the third rotary drive 131 is connected to the clamping drive 132, thereby controlling the overall rotation of the clamping drive 132. The clamping frame 133 includes two clamping claws, which are symmetrically arranged to form a clamping opening for clamping the crucible. The two clamping claws are mounted on the output end of the clamping drive 132. The clamping drive 132 controls the opening and closing of the two clamping claws to achieve the clamping and placement of the crucible. In this embodiment, the crucible is placed horizontally on the storage tray. When clamping the crucible on the storage tray, the clamping drive 132 needs to be flipped by the third rotary drive 131 so that the two clamping claws are flipped to the horizontal direction to clamp the crucible on the storage tray. When the crucible needs to be moved to the waste sample box 30 to empty the floating ash, the third rotary drive 131 is activated to rotate, causing the clamping drive 132 and the clamping frame 133 to flip again, so that the opening of the crucible held by the two clamping claws rotates to the side, slightly downward, or downward, to ensure that the crucible can empty the waste sample or floating ash into the waste sample box 30. When the crucible after emptying the floating ash needs to be transferred to the cleaning assembly 21 or the drying assembly 22 for cleaning, the crucible is flipped to the side on the clamping frame 133 under the control of the third rotary drive 131, and the interior of the crucible is aligned with the brushing structure of the cleaning assembly 21, and the exterior of the crucible is aligned with the ultrasonic cleaning structure of the cleaning assembly 21, to ensure that the crucible is thoroughly cleaned.

[0044] Preferably, the clamping assembly 13 further includes a rotation positioning sensor, which is mounted on the third rotation drive 131 and electrically connected to the clamping drive 132 to sense and position the rotation of the clamping drive 132, thereby controlling the clamping drive 132 to rotate to different angles. Preferably, the third rotation drive 131 is a rotary motor. Preferably, the rotation angle range of the clamping drive 132 is 0° to 360°.

[0045] In use, first rotate the storage tray to rotate the crucible to be cleaned to the preset clamping position. Activate the clamping drive 132 of the clamping assembly 13 to flip the clamping opening of the clamping frame 133 to a horizontal position. Then, activate the second rotation drive 121 of the lifting assembly 12 to lift the clamping assembly 13, raising the clamping frame 133 to a height above the crucible to be clamped. Next, activate the translation assembly 11 to drive the lifting assembly 12 to move along the guide rail of the translation assembly 11, causing the clamping assembly 13 to move synchronously with the lifting assembly 12 to the clamping position of the crucible. At this time, the clamping frame 133 is positioned above the crucible. Then, activate the second rotation drive 121 of the lifting assembly 12 to lower the clamping frame 133, so that the clamping opening of the clamping frame 133 surrounds the outside of the crucible. Finally, control the clamping drive 132 of the clamping assembly 13 to clamp the outer wall of the crucible, achieving positioning and clamping of the crucible.

[0046] Then, the lifting assembly 12 is raised to drive the clamping frame 133 to lift the crucible and detach it from the storage tray. The translation assembly 11 controls the clamping frame 133 holding the crucible to move above the waste sample box 30, and the lifting assembly 12 is lowered to allow the crucible to extend into the waste sample box 30. The clamping drive 132 of the clamping assembly 13 controls the clamping frame 133 to flip, so that the waste sample or floating ash in the crucible is poured into the waste sample box 30, completing the initial cleaning of the crucible. Then, the lifting assembly 12 is controlled to rise and move along the guide rail of the translation assembly 11, so that the crucible on the clamping frame 133 is moved above the cleaning assembly 21. The lifting assembly 12 is then controlled to fall so that the crucible is inserted into the preset cleaning position of the cleaning assembly 21 for cleaning. After cleaning, the crucible is lifted off the cleaning assembly 21 by the lifting assembly 12 and moved above the drying assembly 22 by the control of the translation assembly 11. The lifting assembly 12 is then controlled to fall so that the crucible is inserted into the drying assembly 22 for hot air drying. After drying, the lifting assembly 12 is controlled to drive the clamping frame 133 to rise so that the crucible is removed from the drying assembly 22 and is above the clamping position of the storage tray. The clamping drive 132 is controlled to flip the clamping frame 133 to flip the crucible to a horizontal position. The lifting assembly 12 is then controlled to drive the clamping assembly 13 to fall so that the cleaned crucible can be placed on the storage tray for use.

[0047] like Figure 1 , Figure 3 and Figure 4As shown, the cleaning assembly 21 includes a cleaning chamber 211, a brush head 212, an ultrasonic component 213, and a rinsing component 214. The brush head 212 is used to brush the inner surface of the crucible in the cleaning chamber 211, and the ultrasonic component 213 is used to perform ultrasonic vibration on the outer surface of the crucible. The brush head 212 and the ultrasonic component 213 are symmetrically arranged and installed on both sides of the cleaning chamber 211 along the horizontal movement direction of the clamping assembly 13, so that after the clamping assembly 13 clamps the crucible into the cleaning chamber 211, the inside of the crucible corresponds to the brush head 212, and the outside of the crucible corresponds to the ultrasonic component 213, thereby achieving simultaneous cleaning of the inside and outside of the crucible. A rinsing component 214 is installed on the cleaning chamber 211 and is used to inject water into the cleaning chamber 211 to rinse the crucible. The rinsing component 214 includes an inlet pipe 2141 and a rinsing pipe 2143 installed on the side wall of the cleaning chamber 211, a rinsing nozzle located inside the cleaning chamber 211 and connected to the rinsing pipe 2143, and a drain pipe 2142 installed on the bottom wall of the cleaning chamber 211. Both the inlet pipe 2141 and the rinsing pipe 2143 can be connected to an external water supply device to supply water into the cleaning chamber 211. The rinsing nozzle is positioned corresponding to the crucible inside the cleaning chamber 211 to spray water onto the surface of the crucible for rinsing. Water valves are installed on both the inlet pipe 2141 and the rinsing pipe 2143 to control the time, flow rate, or flow velocity of the water inlet. A water valve is also installed on the drain pipe 2142.

[0048] Preferably, the cleaning assembly 21 further includes an overflow chamber 215, which is located on one side of the cleaning chamber 211 to receive the cleaning water overflowing from the cleaning chamber 211 and prevent it from flowing out of the cleaning chamber 211 and causing contamination. Preferably, the flushing component 214 further includes a liquid level sensor, which is installed on the cleaning chamber 211 and / or the overflow chamber 215 to detect the position of the liquid in the cleaning chamber 211 and / or the overflow chamber 215 so that it can be discharged in a timely manner through the drain pipe 2142.

[0049] The drying assembly 22 includes a drying chamber 221, a front nozzle 222 for hot air drying of the inner surface of the crucible in the drying chamber 221, and a rear nozzle 223 for hot air drying of the outer surface of the crucible in the drying chamber 221. The drying chamber 221 is located on one side of the crucible clamping position preset on the storage tray, so that after the crucible is dried, the transfer mechanism 10 can clamp and transfer the crucible to the storage tray. Preferably, in this embodiment, the crucible clamping position preset on the storage tray is located between the waste sample box 30 and the cleaning chamber 211. Therefore, the drying chamber 221 is located between the waste sample box 30 and the cleaning chamber 211, and the overflow chamber 215 is located between the drying chamber 221 and the cleaning chamber 211. The drying chamber 221, the overflow chamber 215, and the cleaning chamber 211 are connected to form an integral structure. The front nozzle 222 and the rear nozzle 223 are symmetrically arranged and installed on both sides of the drying chamber 221 along the horizontal movement direction of the clamping assembly 13, so that after the clamping assembly 13 clamps the cleaned crucible into the drying chamber 221, the inside of the crucible corresponds to the front nozzle 222 and the outside of the crucible corresponds to the rear nozzle 223, thereby achieving simultaneous drying of the inside and outside of the crucible.

[0050] like Figure 3 , Figure 4 and Figure 5As shown, the brush head component 212 includes a brush head 2121, a fourth rotary drive component 2122, a telescopic drive component 2123, and a telescopic seal component 2124. The brush head 2121 is disposed inside the cleaning chamber 211, and the fourth rotary drive component 2122 is disposed outside the cleaning chamber 211. A through hole is provided on the side wall of the cleaning chamber 211. The output end of the fourth rotary drive component 2122 is movably inserted into the cleaning chamber 211 through the through hole and fixed to the brush head 2121 to control the rotation of the brush head 2121. Through cooperation with the flushing component 214, the inner surface of the crucible is brushed. The telescopic drive component 2123 is located outside the cleaning chamber 211, and the output end of the telescopic drive component 2123 is fixed to the outer wall of the cleaning chamber 211. The fixed end of the telescopic drive component 2123 is fixed to the fourth rotary drive component 2122 through a bracket. Thus, activating the telescopic drive component 2123 can control the fourth rotary drive component 2122 to move toward or away from the cleaning chamber 211, thereby driving the brush head 2121 to move into the crucible and contact the inner surface of the crucible, ensuring effective cleaning of the crucible. A telescopic seal 2124 is disposed outside the cleaning chamber 211 and sleeved on the outside of the output shaft of the fourth rotary drive 2122. One end of the telescopic seal 2124 is sealed and installed on the outer wall of the cleaning chamber 211, and the other end is sealed and connected to the fixed end of the fourth rotary drive 2122 to seal between the cleaning chamber 211 and the fourth rotary drive 2122, preventing the cleaning water in the cleaning chamber 211 from flowing out to the outside through the through hole. At the same time, the telescopic seal 2124 can guide the axial movement of the fourth rotary drive 2122 along the through hole. Preferably, the fourth rotary drive 2122 is a rotary motor; the telescopic drive 2123 is a telescopic cylinder; and the telescopic seal 2124 is a telescopic bellows.

[0051] The ultrasonic component 213 includes an ultrasonic transducer 2131 and an ultrasonic drive 2132. The ultrasonic transducer 2131 is located inside the cleaning chamber 211, and the ultrasonic drive 2132 is located outside the cleaning chamber 211. The output end of the ultrasonic transducer 2131 is connected to the ultrasonic drive 2132, so that the ultrasonic transducer 2131 can be controlled to vibrate through the ultrasonic drive 2132 to perform ultrasonic vibration cleaning on the outer surface of the crucible. The ultrasonic transducer 2131 and the brush head 2121 are respectively located on opposite sides inside the cleaning chamber 211 to ensure that the inner surface of the crucible corresponds to the brush head and the outer surface of the crucible corresponds to the ultrasonic transducer 2131, so as to achieve simultaneous cleaning of the inner and outer surfaces of the crucible.

[0052] like Figure 1 , Figure 3 and Figure 4As shown, the crucible cleaning device also includes a sealing assembly 50 installed on the upper end of the cleaning mechanism 20. The sealing assembly 50 includes two sealing plates 51 and a sealing drive 52 for driving the two sealing plates 51 to open and close. In this embodiment, the two sealing plates 51 are symmetrically arranged and slidably installed on the cleaning chamber 211 and / or overflow chamber 215 and / or drying chamber 221. The output end of the sealing drive 52 is connected to the sealing plates 51. The sealing drive 52 can control the opening and closing of the two sealing plates 51 to seal the upper ports of the cleaning chamber 211 and / or overflow chamber 215 and / or drying chamber 221, preventing cleaning water from flowing out from the upper end of the cleaning chamber 211 and / or overflow chamber 215 when cleaning the crucible. At the same time, sealing the drying chamber 221 can prevent hot air from blowing out of the drying chamber 221, thereby improving drying efficiency.

[0053] Two sealing plates 51 are provided with clearance grooves 511 on their opposite sides, so that after the two sealing plates 51 are joined, a clearance hole is formed for the clamping frame 133 to pass through. When the transfer mechanism 10 clamps the crucible and moves it to the cleaning chamber 211 and extends the crucible into the cleaning position inside the cleaning chamber 211, or moves it to the drying chamber 221 and extends the crucible into the drying position inside the drying chamber 221, the sealing drive 52 is activated to move the two sealing plates 51 toward each other to seal the upper port of the cleaning chamber 211 and / or the drying chamber 221. At this time, the clearance hole formed between the two sealing plates 51 allows the clamping frame 133 above the crucible to pass through, so that the crucible is always firmly clamped during the cleaning process, ensuring the cleaning range and improving the cleaning quality.

[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
