Description

Technical Field

[0001] This application relates to the technical field of cleaning devices, and particularly to a sample bucket cleaning device. Background Art

[0002] Currently, in the coal sampling, preparation and analysis industry, after the coal samples are crushed and reduced in the sampling system, they are encapsulated in coal sample buckets through an encapsulation system and then transported to the sample preparation system for coal sample preparation. In addition, in the sample preparation process, the coal samples prepared by each sample preparation unit are also contained and transported through coal sample buckets or containers. During the transportation of coal samples through coal sample buckets or containers, there are more or less coal sample residues in the sample buckets. If the sample buckets or containers are not cleaned, the residual coal samples will flow into the next sample, causing pollution to the subsequent samples and resulting in inaccurate sample preparation data.

[0003] Currently, in the industry, the general methods for cleaning sample buckets or related containers include:

[0004] 1. A vibrator or pneumatic hammer device is installed on the sample bucket jaw, and the sample bucket is cleaned by vibration or knocking;

[0005] 2. A high-pressure nozzle is installed at the end, and the sample bucket is cleaned by compressed air.

[0006] The above two methods have a certain effect on coal samples with low humidity and viscosity. However, for samples with relatively high humidity and viscosity, due to the large adhesion force, they cannot be cleaned thoroughly, and there will still be a lot of samples adhering to the inner surface of the container.

[0007] 3. A robot is used to grip the sample bucket or container and pour it repeatedly, and a rotary brush is used to clean the sample bucket in cooperation.

[0008] Although the third method has an ideal cleaning effect, its structure is relatively complex, and the brush cannot be self-cleaned, which affects the cleaning efficiency of the sample bucket.

[0009] Therefore, in view of the above technical problems, how to provide a sample bucket cleaning device with a reliable cleaning effect and capable of self-cleaning the brush is a technical problem that those skilled in the art need to solve. Utility Model Content

[0038] In order to enable those skilled in the art of this technology to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0039] As Figure 1 shown, in this embodiment, a sample bucket cleaning device is provided. The device includes a fixed seat 1, a driving member, a rotating rod 10, and a compressed air source. The fixed seat 1 is installed on the pouring hopper and serves as the support structure of the entire cleaning device. According to the positional relationship between the cleaning device and the pouring hopper, the fixed seat 1 can be set as an L-shaped structure, and the strength of the bent portion of the fixed seat 1 can be strengthened through structures such as reinforcing rib plates.

[0040] The driving member is arranged on one end face of the fixed seat 1. Please refer toFigure 1 The driving member includes a telescopic driving member 3 and a rotary driving member. The telescopic driving member 3 is installed on the fixed seat 1, and the rotary driving member is installed on the moving end of the telescopic driving member 3, so that while the rotary driving member drives rotation, it can also make reciprocating motion along with the telescopic driving member 3.

[0041] The rotary rod 10 is arranged at the output end of the rotary driving member, so as to drive the rotary rod 10 to rotate. At the same time, combined with the telescopic action of the telescopic driving member 3, the operation of the rotary rod 10 rotating while making reciprocating motion is realized. It should be noted that the telescopic direction of the telescopic driving member 3 should be consistent with the axial direction of the rotary rod 10, so that when the rotary rod 10 makes reciprocating motion, it can act along its axis.

[0042] Among them, the rotary rod 10 is hollow, that is, it has a hollow channel inside, and a pneumatic rotary air knife 12 is arranged at the end of the rotary rod 10 away from the rotary driving member. The pneumatic rotary air knife 12 is provided with a jet nozzle, and the jet nozzle is communicated with the hollow channel of the rotary rod 10. At the same time, a brush assembly is also arranged at the end of the rotary rod 10. The brush assembly and the pneumatic rotary air knife 12 are located at the same end of the rotary rod 10. The brush assembly includes a support body 13 communicated with the hollow channel inside the rotary rod 10 and a brush 14 arranged on the support body 13. Specifically, the support body 13 is provided with small holes for jetting air towards the brush 14, and the small holes are communicated with the hollow channel of the rotary tube.

[0043] On the basis of the above embodiment, the compressed air source is also connected to the hollow channel of the rotary rod 10. Of course, the connection position of the compressed air source is different from that of the brush assembly and the pneumatic rotary air knife 12. Preferably, the connection position of the compressed air source and the rotary rod 10 is set at one end away from the pneumatic rotary air knife 12.

[0044] The compressed air source is used to provide high-speed compressed air for the rotary rod 10, and the compressed air is ejected through the jet nozzle of the pneumatic rotary air knife 12 and the small holes of the support body 13. Thus, while the brush assembly cleans the sample bucket 16, high-speed gas can be used for auxiliary cleaning, and after the brush assembly finishes cleaning, the gas ejected through the small holes is used to clean the brush 14. Moreover, the brush 14 can also throw out the residual materials remaining on the brush 14 under the rotation of the rotary rod 10.

[0045] Based on the above embodiments, the present application is installed on the tipping hopper through the fixed seat 1. The fixed seat 1 serves as the main bearing mechanism of the device. A driving member is provided on the fixed seat 1. The driving member includes a telescopic driving member 3 and a rotary driving member. The telescopic driving member 3 is installed on the fixed seat 1, and the rotary driving member is installed at the power end of the telescopic driving member 3. The output end of the rotary driving member is provided with a rotary rod 10, so that the rotary rod 10 is driven by the driving member to perform telescopic and rotary motions. An air-driven rotary air knife 12 and a brush assembly are provided at the end of the rotary rod 10 away from the rotary driving member. During use, the brush assembly and the air-driven rotary air knife 12 are placed inside the sample bucket 16 by the extending action of the telescopic driving member 3. The rotary driving member drives the rotary rod 10 to rotate, so as to realize the motion of the brush assembly rotating and telescoping while in contact with the inner wall of the sample bucket 16, thereby completing the cleaning of the entire inside of the sample bucket 16. At the same time, the inside of the rotary rod 10 is hollow and is externally connected to a compressed air source, so that the compressed air passes through the hollow channel of the rotary rod 10 and is ejected from the small holes in the air-driven rotary air knife 12 at the end and the brush assembly to perform auxiliary cleaning work. During the cleaning process of the compressed air, the dust removal system will cooperate to collect the cleaned coal samples. After the cleaning is completed, the rotary rod 10 drives the brush assembly to rotate at a high speed again, and with the assistance of the small holes, the brush 14 is purged to perform self-cleaning of the brush 14.

[0046] The telescopic driving member 3 includes a rodless cylinder provided on the fixed seat 1. The rodless cylinder adopts a magnetic coupling rodless cylinder, and the rodless cylinder with double guide shafts is adopted. The column part of the rodless cylinder is arranged on the fixed seat 1, and the pneumatic power end is used to drive the forward and backward reciprocating motion of the rotary rod 10. And the cylinder is equipped with double guide shafts by itself, without the need to additionally configure a guide mechanism such as a guide rail. The structure is simple and the operation is reliable. Of course, the telescopic driving member 3 can also adopt a self-guided multi-axis electric cylinder, etc., which is not limited here too much and all fall within the protection scope of the present application.

[0047] Furthermore, an installation seat 4 is provided at the power end of the rodless cylinder. The installation seat 4 serves as a support component for the rotary rod 10, the rotary driving member and the air bag 6, etc., and can drive the three to move stably back and forth.

[0048] To ensure the reasonable telescopic action of the telescopic driving member 3, two limit sensors 2 can be provided on the fixed seat 1. The two limit sensors 2 correspond to the limit positions before and after the action end of the rodless cylinder respectively, so as to perform feedback according to the detection signals of the limit sensors 2.

[0049] Please refer to Figure 1 and Figure 4, the rotation driving member includes a hollow rotating platform 8 provided on the mounting base 4 and a motor 7 mounted in cooperation with the hollow rotating platform 8. The end of the rotating rod 10 is provided at the output end of the hollow rotating platform 8. Specifically, the motor 7 is directly connected to the hollow rotating platform 8, and the output end of the hollow rotating platform 8 is connected to the rotating rod 10, and the driving mechanism directly drives the rotating rod 10 to perform a rotating motion.

[0050] The rotation driving member directly connects the motor 7 to the hollow rotating platform 8, which has a simple and reliable structure and can achieve the high-speed movement of the rotating rod 10. At the same time, the middle of the hollow rotating platform 8 is hollowed out, which is convenient for the rotating rod 10 to pass through the center, so as to realize the purpose of spraying gas from the end of the rotating rod 10 through the compressed air source.

[0051] In addition, a home position switch 9 is provided on the hollow rotating platform 8, and the home position switch 9 is arranged in cooperation with the brush assembly to detect the position of the brush assembly in real time during rotation.

[0052] For the hollow rotating platform 8, components such as a slewing bearing can also be used to ensure that the rotation of the motor 7 can be converted into the rotation of the rotating rod 10.

[0053] The compressed air source includes an air receiver 6 provided on the mounting base 4 and a power blower 15 communicated with the air receiver 6. Please refer to Figure 1 , the compressed air generated by the power blower 15 is transported to the air receiver 6 through a trachea. The air receiver 6 is used to store a certain amount of compressed air, and its air outlet end is communicated with the internal hollow channel of the rotating rod 10 through a solenoid valve 5. During the cleaning work, the solenoid valve 5 is controlled to open, and the compressed air stored in the air receiver 6 is sprayed out from the end of the rotating rod 10 through the pneumatic rotary air knife 12 and small holes to complete the auxiliary cleaning work of the sample bucket 16. At the same time, after the compressed air in the air receiver 6 decreases, the power blower 15 automatically starts to supply air to the air receiver 6.

[0054] In addition, please refer to Figure 1 and Figure 5 , a plurality of support bodies 13 are evenly distributed on the outer periphery of the rotating rod 10, and each support body 13 is arranged in an L shape. The brush 14 can be distributed along the L-shaped structure of the support body 13 on the outer edge of the support body 13, so that the brush 14 can directly contact the bottom surface and side surface of the sample bucket 16. Furthermore, the omnidirectional cleaning of the inside of the sample bucket 16 is realized through the rotation and reciprocating movement of the rotating rod 10.

[0055] Specifically, please refer to Figure 2 , during the cleaning, first, the manipulator grabs the sample bucket 16 and aligns the center of the sample bucket 16 with the axis of the rotating rod 10 to reach the cleaning position, and then the rotating rod 10 drives the brush assembly to rotate and reciprocate back and forth while rotating the bucket under the drive of the telescopic driving member 3 and the rotation driving member, so as to complete the cleaning of the entire inside of the bucket.

[0056] In addition, to ensure the stability of the rotating rod 10 during rotation and reciprocating telescoping, a limiting component 11 can be provided on the hopper. There is a position on the limiting component 11 located on the outer periphery of the rotating rod 10, and the inner ring of the limiting component 11 can slidably abut against the outer periphery of the rotating rod 10, thereby providing stable support for the rotation and telescoping of the rotating rod 10.

[0058] In some embodiments, the brush 14 can be made of nylon matrix material. A plurality of small holes are distributed on the support body 13, and the jet direction of the small holes can be parallel or intersect with the bristles of the brush 14, which can realize auxiliary cleaning during the cleaning process and self-cleaning of the brush 14, and there is no dead zone cleaning between the brush 14 and the bottom of the barrel during the cleaning process.

[0059] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.
