Description

Technical Field

[0001] This application relates to the field of testing equipment, and more particularly to a cleaning device for sample blocks. Background Technology

[0002] The caking index is a key indicator characterizing the caking and coking properties of bituminous coal. The measurement procedure for the caking index is based on the national standard GB / T5447-2014. The national standard stipulates that before conducting the drum test, when the sample block (coal sample) is taken out of the crucible, if there are coke particles on the sample block, they need to be brushed off into the crucible.

[0003] In existing technologies, the determination of the adhesion index is done manually. When cleaning the sample block, the operator usually picks up the sample block with tweezers and then gently brushes the side of the sample block with a brush to let the adhering char debris fall into the crucible. The manual cleaning of the sample block is very cumbersome, the labor intensity of the personnel is high, and there are subjective differences that can affect the experimental results. Utility Model Content

[0004] This application provides a sample block cleaning device that can automate cleaning and reduce differences caused by human factors.

[0005] This application provides a sample block cleaning device, including a telescopic rotary drive mechanism, a picking mechanism, and a cleaning mechanism; the telescopic rotary drive mechanism is disposed above the sample block along the Z-axis direction;

[0006] The pickup mechanism is connected to the output end of the telescopic rotary drive mechanism. The pickup mechanism is used to connect with the sample block, and the telescopic rotary drive mechanism is used to drive the pickup mechanism and the sample block to move in the Z-axis direction and rotate around the Z-axis direction.

[0007] The cleaning mechanism includes a funnel, a telescopic component, and a brush. The funnel includes two discrete cone shells, and the telescopic component is connected to each of the discrete cone shells in a one-to-one correspondence. The telescopic component drives the two discrete cone shells to close together in the X-axis direction to form a funnel. The brush is set on the discrete cone shells and is used to clean the sample block.

[0008] Preferably, the telescopic rotary drive mechanism is configured as a telescopic rotary cylinder.

[0009] Preferably, the picking mechanism includes a connecting shaft, a suction cup, and an elastic element; the connecting shaft is arranged along the Z-axis direction, one end of the connecting shaft is connected to the telescopic rotation drive mechanism, and the suction cup is slidably connected to the other end of the connecting shaft along the Z-axis direction; the elastic element is arranged between the suction cup and the connecting shaft, and the telescopic direction of the elastic element is configured in the Z-axis direction.

[0010] Preferably, the connecting shaft has a sliding hole along the Z-axis, and the suction handle of the suction cup is slidably disposed in the sliding hole along the Z-axis.

[0011] Preferably, a guide limiting pin is provided on the connecting shaft; a guide groove is provided on the suction handle of the suction cup, and the length direction of the guide groove is configured in the Z-axis direction; one end of the guide limiting pin is located in the guide groove.

[0012] Preferably, the funnel is split in half to form two discrete conical shells, the shape of which is configured as a semi-conical shell, and the two discrete conical shells are located at the same height; the funnel and the picking mechanism are coaxially corresponding along the Z-axis.

[0013] Preferably, the funnel formed by the two separate conical shells has a large port and a small port, with the large port located above the small port, and the inner diameter of the large port being 1.5 to 3 times the inner diameter of the small port.

[0014] Preferably, the discrete cone shell has a back plate on the side opposite to the suction cup, and the back plate is detachably connected to the telescopic end of the telescopic component.

[0015] Preferably, the telescopic component is configured as a telescopic cylinder or an electric push rod, and the telescopic component is connected to the discrete cone shell in a one-to-one correspondence.

[0016] Preferably, the discrete cone shell is provided with a mounting groove; the brush includes a mounting part and brush bristles, the mounting part is disposed in the mounting groove, the brush bristles are connected to the mounting part, and the brush bristles are in contact with the sample pressing block.

[0017] The cleaning device of this application has at least the following beneficial effects:

[0018] In this application, the cleaning device, when cleaning the sample block, uses a telescopic rotary drive mechanism to drive the pickup mechanism downward along the Z-axis until the pickup mechanism is connected to the sample block. The telescopic rotary drive mechanism then drives the pickup mechanism and the sample block upward. After reaching the same height as the two discrete cone shells, the telescopic component of the cleaning mechanism brings the two discrete cone shells closer to the sample block and finally surrounds them to form a complete funnel. The funnel surrounds the sample block, and the brush on the funnel contacts the sample block. When the telescopic rotary drive mechanism drives the pickup mechanism and the sample block to rotate around the Z-axis, the brush rotates relative to the outer periphery of the sample block. The brush sweeps off the coke debris from the outer periphery of the sample block. The swept-off coke debris falls back into the crucible through the small port of the funnel. This achieves automated cleaning, reduces differences caused by human factors, and because the inner diameter of the funnel gradually increases along its axial direction, it can be matched to surround sample blocks of different sizes.

[0034] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0036] like Figure 1 As shown, this embodiment discloses a cleaning device for a sample compact 400. The cleaning device includes a telescopic rotary drive mechanism 100, a picking mechanism 200, and a sweeping mechanism 300. The telescopic rotary drive mechanism 100 is used to drive the picking mechanism 200 and the sample compact 400 to move up and down in the Z-axis direction and rotate around the Z-axis direction. The picking mechanism 200 is used to connect with the sample compact 400. The sweeping mechanism 300 is used to sweep off the burnt debris on the sample compact 400.

[0037] To facilitate understanding of the technical solution of this embodiment, the directions of the accompanying drawings of this embodiment are defined as follows: the height direction is defined as the Z-axis direction, the horizontal direction is defined as the X-axis direction, and the vertical direction is defined as the Y-axis direction. The Z-axis direction, X-axis direction, and Y-axis direction intersect each other perpendicularly to form a three-dimensional coordinate system. The accompanying drawings of this embodiment only illustrate the Z-axis direction and the X-axis direction.

[0038] like Figure 2 As shown, the telescopic rotary drive mechanism 100 is capable of telescopic and rotary motion. Its specific structure can be found in existing technology. In this embodiment, the telescopic rotary drive mechanism 100 is preferably a telescopic rotary cylinder. Since the telescopic rotary drive mechanism 100 is existing technology, this embodiment only shows a partial simplified diagram.

[0039] like Figure 3As shown, the pickup mechanism 200 includes a connecting shaft 210, a suction cup 220, and an elastic element 230. The connecting shaft 210 is vertically arranged along the Z-axis direction. The upper end of the connecting shaft 210 is coaxially connected to the output shaft of the telescopic rotation drive mechanism 100. The telescopic rotation drive mechanism 100 can drive the connecting shaft 210 to perform telescopic movement in the Z-axis direction and drive the connecting shaft 210 to rotate around the Z-axis direction. The suction cup 220 is slidably connected to the connecting shaft 210. The suction cup 220 can slide relative to the connecting shaft 210 in the Z-axis direction. The suction cup 220 can communicate with an external negative pressure source and generate suction force. The suction cup 220 is adsorbed and connected to the sample block 400. The elastic element 230 is disposed between the connecting shaft 210 and the suction cup 220. One end of the elastic element 230 abuts against the connecting shaft 210, and the other end abuts against the suction cup 220. The telescopic direction of the elastic element 230 is configured in the Z-axis direction.

[0040] like Figure 3 As shown, during testing, the sample block 400 needs to be removed from the crucible 500. However, the heights of different sample blocks 400 will vary. For example, sample blocks 400 with greater shrinkage will be lower in height, while sample blocks 400 with less shrinkage will be higher in height. In this embodiment, by setting the suction cup 220 as a sliding component, it can adapt to the removal and placement of sample blocks 400 of different heights. When the sample block 400 is removed from the crucible 500 where the sample block 400 is higher, the bottom of the suction cup 220 is subjected to an upward force, and the suction cup 220 slides upward and compresses the elastic element 230. When the sample block 400 is removed from the crucible 500 where the sample block 400 is lower, the elastic element 230 supports the suction cup 220, ensuring that the suction cup 220 is in a low position. This design can adapt to the removal and placement of sample blocks 400 of different heights.

[0041] like Figure 3 As shown, in this embodiment, a sliding hole 210a is provided on the lower end face of the connecting shaft 210. The sliding hole 210a is circular in shape and extends upward along the Z-axis direction. The sliding hole 210a is coaxially arranged with the connecting shaft 210.

[0042] like Figure 3 As shown, the suction cup 220 includes a suction cup body 221 and a suction handle 222. The suction cup body 221 is used to adsorb the sample block 400. The suction handle 222 is disposed at the upper end of the suction cup body 221, extends vertically upward, and is circular in shape. The suction handle 222 is coaxially inserted into the sliding hole 210a, and can slide relative to the inner peripheral wall of the sliding hole 210a in the Z-axis direction. In this embodiment, the suction cup 220 can slide in the Z-axis direction through the cooperation of the suction handle 222 and the sliding hole 210a. At the same time, the sliding hole 210a can restrict the position of the suction cup 220 in the horizontal direction.

[0043] like Figure 3As shown, in this embodiment, a guide pin 211 is provided on the connecting shaft 210. The guide pin 211 passes through the connecting shaft 210 radially, and one end of the guide pin 211 extends into the sliding hole 210a. A guide groove 220a is provided on the suction handle 222 of the suction cup 220. The length direction of the guide groove 220a is configured in the Z-axis direction. One end of the guide pin 211 is inserted into the guide groove 220a. The outer diameter of 1 is slightly smaller than the inner width of the guide groove 220a, for example, the outer diameter is 0.95 to 0.99 times the inner width. Through the cooperation of the guide limit pin 211 and the guide groove 220a, the suction cup 220 can only slide relative to the connecting shaft 210 in the Z-axis direction, and cannot rotate around the Z-axis direction. At the same time, the guide limit pin 211 can prevent the suction cup 220 from falling down to the bottom of the connecting shaft 210, thus preventing the suction cup 220 from disengaging from the connecting shaft 210.

[0044] like Figure 3 As shown, in some preferred embodiments, the elastic element 230 is preferably a spring. The spring is located inside the sliding hole 210a, and the spring is coaxially sleeved on the outer circumference of the suction handle 222. The upper end of the spring abuts against the inner top wall of the sliding hole 210a, and the lower end of the spring abuts against the shoulder surface of the suction handle 222.

[0045] like Figure 4 As shown, the cleaning mechanism 300 includes a funnel 310, a telescopic component 320, and a brush 330, as detailed below:

[0046] like Figure 5 As shown, the funnel 310 includes two discrete conical shells 311. The funnel 310 is cut in half along its axial direction to form two discrete conical shells 311. The two discrete conical shells 311 are located at the same height and can be brought together along the X-axis to form a complete funnel 310. The funnel 310 formed by the enclosed funnel is coaxially corresponding to the suction cup 220 of the pickup mechanism 200 in the Z-axis direction. The funnel 310 formed by the enclosed funnel 311 has a large port and a small port. The large port is located above the small port, and the inner diameter of the large port is 1.5 to 3 times that of the small port. By designing the inner diameter of the large port and the small port, the inner diameter of the funnel 310 gradually increases along its axial direction, which can accommodate sample blocks 400 of different diameters. It should be noted that the inner diameter of the large port of funnel 310 is larger than the outer diameter of suction cup 220, and the inner diameter of the large port of funnel 310 is also larger than the outer diameter of sample block 400.

[0047] like Figure 6As shown, in some preferred embodiments, along the X-axis direction, the discrete cone shell 311 is provided with a back plate 3111 on the outer peripheral side away from the suction cup 220. The back plate 3111 is detachably connected to the telescopic end of the telescopic member 320. For example, the back plate 3111 and the telescopic member 320 are connected by screws or magnetic attraction, which makes it easy to replace different discrete cone shells 311 at any time according to the working conditions, so as to form funnels 310 with larger or smaller specifications.

[0048] like Figure 5 As shown, there are two telescopic components 320, each corresponding to one of the two discrete conical shells 311. The telescopic ends of the telescopic components 320 are connected to the back plate portion 3111 of the discrete conical shells 311. The telescopic direction of the telescopic components 320 is configured in the X-axis direction. The telescopic components 320 can drive the two discrete conical shells 311 to approach and enclose to form a complete funnel 310, or the telescopic components 320 can drive the two discrete conical shells 311 to gradually separate. In this embodiment, the telescopic component 320 is configured as a telescopic cylinder or an electric push rod.

[0049] like Figure 5 As shown, the brush 330 is disposed on one or two discrete cone shells 311. In this embodiment, it is preferable that each discrete cone shell 311 is provided with a brush 330. The brush 330 is used to sweep off the coke residue around the sample block 400. Specifically, the telescopic rotation drive mechanism 100 drives the sample block 400 to move upward, and the two discrete cone shells 311 surround the sample block 400. The telescopic rotation drive mechanism 100 drives the suction cup 220 and the sample block 400 to rotate. The brush 330 contacts the outer periphery of the sample block 400. As the sample block 400 rotates, the brush 330 sweeps off the coke residue. The swept-off coke residue falls downward into the crucible 500 through the small port below the funnel 310.

[0050] like Figure 6 and Figure 7 As shown, in some preferred embodiments, the discrete conical shell 311 is provided with a mounting groove 311a. The brush 330 includes a mounting part 331 and bristles 332. The mounting part 331 is disposed in the mounting groove 311a, and the bristles 332 are connected to the mounting part 331 and contact the sample pressing block 400. In this embodiment, the mounting part 331 is detachably mounted in the mounting groove 311a, and can be removed at any time to replace the bristles 332 with different hardness.

[0051] like Figure 1As shown, in this embodiment, the cleaning device also includes a material tray 600, which is located below the funnel 310. The material tray 600 is horizontally positioned and has at least one crucible positioning hole. The crucible 500 is positioned in the crucible positioning hole. In some preferred embodiments, the crucible 500 is placed in the crucible positioning hole by an external mechanical device (not shown). A sample pressing block 400 is placed inside the crucible 500. The telescopic rotation drive mechanism 100 drives the suction cup 220 to move downward until the suction cup 220 contacts the sample pressing block 400. The suction cup 220 generates a negative pressure through an external negative pressure source and adsorbs the sample pressing block 400. The telescopic rotation drive mechanism 100 then drives the suction cup 220 and the sample pressing block 400 to move upward until the sample pressing block 400 is above the crucible 500.

[0052] When the two separate conical shells 311 are joined together to form a complete funnel 310, the funnel 310 is located above the crucible 500 and is coaxially aligned with a crucible 500 on the material tray 600, so that the coke dust swept off by the brush 330 can fall back into the crucible 500 through the small port below the funnel 310.

[0053] The cleaning device in this embodiment operates as follows:

[0054] 1. An external mechanical device moves the pickup mechanism 200 directly above the crucible 500, so that the suction cup 220 of the pickup mechanism 200 is located directly above the crucible 500.

[0055] 2. The telescopic and rotary drive mechanism 100 drives the suction cup 220 to move downward until the suction cup 220 contacts the sample block 400. The suction cup 220 generates negative pressure through an external negative pressure source and adsorbs the sample block 400.

[0056] 3. The telescopic and rotary drive mechanism 100 drives the suction cup 220 and the sample pressing block 400 to move up to the same height position as the discrete cone shell 311. The telescopic component 320 drives the two discrete cone shells 311 to surround and form a funnel 310 around the sample pressing block 400. After the two discrete cone shells 311 surround and form the funnel 310, the brush 330 on the discrete cone shell 311 is in tangential contact with the side of the sample pressing block 400.

[0057] IV. The telescopic and rotary drive mechanism 100 drives the suction cup 220 and the sample block 400 to rotate. The sample block 400 and the brush 330 move relative to each other. The brush 330 sweeps off the coke residue on the sample block 400. The swept-off coke residue falls downward through the small port of the funnel 310 into the crucible 500. After the coke residue is swept off, the two discrete cone shells 311 gradually separate under the drive of the telescopic component 320.

[0058] 5. The external mechanical device drives the picking mechanism 200 and the sample block 400 after cleaning to rotate to the sample block placement position on the material tray 600. The sample block 400 after cleaning is placed in the sample block placement position. Then, the external mechanical device removes the cleaned crucible 500 from the crucible positioning hole on the material tray 600, and moves another crucible to be cleaned to the crucible positioning hole. The next sample block 400 is cleaned in the same way.

[0059] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
