Description

Technical Field

[0001] The invention mainly relates to the technical field of sample calorific value measurement, in particular to an ignition rod scraping mechanism and an ignition rod full-automatic scraping device. Background Art

[0002] In the intelligent test system, the calorific value of coal is usually determined by ignition of an ignition rod. When measuring the calorific value of coal, due to the difference in coal quality, a layer of molten material will adhere to the surface of the ignition rod after combustion, which has an adverse effect on the ignition rod. Too much molten material adhered to the ignition rod can easily lead to ignition failure, affecting the experimental data. The current cleaning method can only rely on manual cleaning on a regular basis, and manual cleaning has the following disadvantages:

[0003] 1. Manual regular cleaning affects the experimental efficiency and cannot meet the needs of the automated testing system;

[0004] 2. Manual cleaning usually uses pliers to clamp the ignition rod and crush the molten material on the ignition rod to achieve the purpose of cleaning. However, due to the difference in strength between different operators during manual cleaning, it is difficult to control the strength. If the force is too small, the molten material is difficult to clean. If the force is too large, it is easy to damage the ignition rod and reduce the service life of the ignition rod.

[0005] 3. Manual cleaning requires the removal of the ignition rod. In an unmanned testing system, the experimental process needs to be carried out continuously and uninterruptedly. Therefore, removing the ignition rod for cleaning cannot meet the needs of an unmanned testing system. Summary of the invention

[0006] In view of the technical problems existing in the prior art, the present invention provides an ignition rod scraping mechanism and an ignition rod automatic scraping device which can automatically clean molten material, have high cleaning efficiency, good cleaning effect and can be integrated into an unmanned testing system.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] An ignition rod scraping mechanism comprises a driving assembly, a scraping assembly and an elastic assembly, wherein the scraping assembly has an opening at the upper end, a convex structure for scraping the ignition rod is arranged inside the scraping assembly, the interior of the scraping assembly is a hollow structure, the elastic assembly is arranged below the scraping assembly, the driving assembly is used to drive the scraping assembly to rotate so as to drive the convex structure to scrape the ignition rod, and the elastic assembly is used to make the ignition rod contact flexibly with the scraping assembly.

[0009] As a further improvement of the present invention, it also includes a transmission assembly, the driving assembly is connected to the scraping assembly through the transmission assembly, and the driving assembly is used to drive the transmission assembly to move and then drive the scraping assembly to rotate.

[0010] As a further improvement of the present invention, it also includes a connecting shaft, and the transmission assembly is connected to the scraping assembly via the connecting shaft.

[0011] As a further improvement of the present invention: the transmission assembly includes a first moving wheel, a second moving wheel and a transmission belt, the transmission belt is wound around the first moving wheel and the second moving wheel, and the drive assembly is used to drive the first moving wheel to move and then drive the second moving wheel to move.

[0012] As a further improvement of the present invention: the transmission assembly includes a first gear and a second gear that mesh with each other, and the driving assembly is used to drive the first gear to rotate and then drive the second gear to rotate.

[0013] As a further improvement of the present invention, it also includes a telescopic driving component, and the telescopic driving component is used to drive the scraping component to perform telescopic movement in the horizontal direction.

[0014] As a further improvement of the present invention: the telescopic drive component is any one of a cylinder, a motor or a telescopic chain.

[0015] As a further improvement of the present invention: the opening of the scraping and sweeping assembly is any one of a bell mouth, a straight opening or an opening with a chamfer.

[0016] As a further improvement of the present invention: the convex structure is a gear structure.

[0017] As a further improvement of the present invention: the gear structure is any one or more of triangular teeth, trapezoidal teeth, square teeth or semicircular teeth.

[0018] As a further improvement of the present invention: the elastic component is any one of a spring, an air cushion and rubber.

[0019] The present invention also provides an ignition rod fully automatic scraping device, comprising a lifting mechanism, an oxygen bullet fixing mechanism and the ignition rod scraping mechanism as described above, wherein the oxygen bullet fixing mechanism is used to fix the oxygen bullet, and the lifting mechanism is used to drive the oxygen bullet fixing mechanism to perform up and down lifting movements.

[0020] As a further improvement of the present invention, it also includes an ash collecting mechanism, which is arranged below the ignition rod scraping mechanism and is used to collect the molten material scraped down by the ignition rod scraping mechanism.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] 1. The ignition rod scraping mechanism of the present invention can insert the ignition rod on the oxygen bomb into the opening of the scraping assembly through a manipulator or other automatic device when the ignition rod needs to be cleaned. Since there is a convex structure below the opening, when the driving assembly drives the scraping assembly to rotate, the convex structure rotates to contact the molten material on the ignition rod and scrapes it off. In the process of the ignition rod contacting the convex mechanism, since an elastic component is provided below, there is a flexible contact between the ignition rod and the convex structure, thereby ensuring that the convex structure will not damage the ignition rod in the process of scraping the molten material. The ignition rod scraping mechanism of the present invention has the advantages of simple structure, high cleaning efficiency, and good cleaning effect.

It can be applied to an unmanned test system to realize the full automation of sample calorific value measurement.

[0023] 2. The fully automatic scraping device for the ignition rod of the present invention is provided with a lifting mechanism and an oxygen bullet fixing mechanism. When the ignition rod needs to be cleaned, the lifting mechanism adjusts the oxygen bullet fixing mechanism to an appropriate height, and fixes the oxygen bullet on the oxygen bullet fixing mechanism through a manipulator. Then the lifting mechanism drives the oxygen bullet fixing mechanism to descend to send the ignition rod into the scraping assembly of the ignition rod scraping mechanism. While the scraping assembly rotates, the lifting mechanism drives the ignition rod to reciprocate up and down, and cleans the molten material on the ignition rod along the circumferential direction of the ignition rod and the axial direction of the ignition rod. When the molten material is scraped clean, the lifting mechanism rises and drives the oxygen bullet fixing mechanism to rise, the oxygen bullet fixing mechanism is released, and the manipulator takes away the oxygen bullet to complete the ignition rod cleaning work. No manual intervention is required in the whole process, which can ensure that the molten material on the ignition rod is automatically cleaned, and at the same time ensure that the ignition rod will not be damaged, which can effectively extend the service life of the ignition rod and meet the requirements of the unmanned testing system for automatic scraping of the ignition rod.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 3 As shown, this embodiment provides an ignition rod scraping mechanism 102, including a driving component 1, a scraping component 2 and an elastic component 3. The scraping component 2 has an opening 21 at the upper end, and a convex structure 4 for scraping the ignition rod is provided inside the scraping component 2. The interior of the scraping component 2 is a hollow structure. The elastic component 3 is arranged below the scraping component 2. The driving component 1 is used to drive the scraping component 2 to rotate so as to drive the convex structure 4 to scrape the ignition rod, and the elastic component 3 is used to make the ignition rod and the scraping component 2 in flexible contact.

[0036] When the ignition rod needs to be cleaned, the ignition rod on the oxygen bomb can be inserted into the opening 21 of the scraping assembly 2 by a manipulator or other automatic device. Since a convex structure 4 is provided in the scraping assembly 2, when the driving assembly 1 drives the scraping assembly 2 to rotate, the convex structure 4 rotates to contact the molten material on the ignition rod and scrapes it off. In the process of the ignition rod contacting the convex structure 4, since the elastic assembly 3 is provided below, there is a flexible contact between the ignition rod and the convex structure 4, thereby ensuring that the convex structure 4 will not damage the ignition rod in the process of scraping the molten material.

[0037] The ignition rod scraping mechanism 102 in this embodiment has the advantages of simple structure, high cleaning efficiency, and good cleaning effect. It can be integrated into an unmanned testing system to realize the automatic scraping process of the molten material on the ignition rod. Since there is a flexible contact between the ignition rod and the convex structure 4, it can not only scrape the molten material on the ignition rod clean, but also will not affect the service life of the ignition rod, thereby realizing full automation of the sample calorific value measurement process.

[0038] In this embodiment, a transmission assembly 5 is further included, and the driving assembly 1 is connected to the scraping assembly 2 through the transmission assembly 5. The driving assembly 1 is used to drive the transmission assembly 5 to move and then drive the scraping assembly 2 to rotate. Further, in a preferred embodiment, a connecting shaft 6 is further included, and the transmission assembly 5 is connected to the scraping assembly 2 through the connecting shaft 6. When cleaning the ignition rod, the driving assembly 1 drives the transmission assembly 5 to move, and the transmission assembly 5 drives the connecting shaft 6 to rotate, thereby driving the scraping assembly 2 to rotate, so that the convex structure 4 rotates along the circumferential direction of the ignition rod to scrape off the melt.

[0039] In this embodiment, the transmission assembly 5 includes a first moving wheel 51, a second moving wheel 52 and a transmission belt 53. The transmission belt 53 is wound around the first moving wheel 51 and the second moving wheel 52. The driving assembly 1 is used to drive the first moving wheel 51 to move and then drive the second moving wheel 52 to move.

[0040] In this embodiment, the driving assembly 1 is a motor. In other embodiments, the driving assembly 1 may also be other driving mechanisms such as a cylinder or an oil cylinder. The driving assembly 1 is connected to the first moving wheel 51, and is used to drive the first moving wheel 51 to rotate, thereby driving the transmission belt 53 to move. Since the transmission belt 53 is wound around the first moving wheel 51 and the second moving wheel 52, the second moving wheel 52 rotates under the drive of the transmission belt 53, thereby driving the scraping assembly 2 to rotate, so that the convex structure 4 rotates to scrape the melt on the ignition rod.

[0041] In this embodiment, a telescopic drive assembly 7 is also included, and the telescopic drive assembly 7 is used to drive the scraping assembly 2 to perform telescopic movement in the horizontal direction. Further, in a preferred embodiment, the telescopic drive assembly 7 is a cylinder, and the drive assembly 1 and the scraping assembly 2 are installed on the telescopic drive assembly 7 through a mounting seat. When the ignition rod needs to be placed in the opening 21 of the scraping assembly 2, the telescopic drive assembly 7 drives the scraping assembly 2 to extend forward, so that the ignition rod can be placed in the scraping assembly 2. In other embodiments, the telescopic drive assembly 7 can be a motor or other telescopic mechanism such as a telescopic chain.

[0042] In this embodiment, the opening 21 of the scraping assembly 2 is a trumpet-shaped opening, with a large upper end and a small lower end. When the ignition rod is inserted into the scraping assembly 2, the trumpet-shaped opening 21 can facilitate the insertion of the ignition rod, and the small lower end can realize the correction of the position of the ignition rod. In other embodiments, the opening 21 of the scraping assembly 2 can be a straight opening or an opening 21 with a chamfer.

[0043] In this embodiment, the convex structure is a tooth-shaped structure, and its shape can be a triangle, a trapezoid, a square, a semicircle or other irregular shapes, as long as it can scrape the molten material off.

[0044] In this embodiment, the elastic component 3 is a spring, and the elastic component 3 is arranged between the scraping component 2 and the connecting shaft 6. Since the scraping component 2 is a hollow structure inside, after the ignition rod is inserted from the opening 21 of the scraping component 2, the bottom end of the ignition rod will first contact the spring. During the rotation of the scraping component 2, the ignition rod is always in flexible contact with the scraping component 2 to ensure that the ignition rod is not damaged during the scraping process. It can be understood that in other embodiments, the elastic component 3 can also be other conventional elastic parts such as air cushions and rubber.

[0045] Embodiment 2

[0046] like Figure 4 As shown, this embodiment is basically the same as the first embodiment, except that, in this embodiment, the transmission assembly 5 includes a first gear 54 and a second gear 55 meshing with each other, and the driving assembly 1 is used to drive the first gear 54 to rotate and then drive the second gear 55 to rotate. The second gear 55 is connected to the scraping assembly 2 through the connecting shaft 6, and the second gear 55 rotates to drive the scraping assembly 2 to rotate, so that the convex structure 4 rotates to scrape the melt on the ignition rod, thereby realizing automatic cleaning of the melt on the ignition rod.

[0047] Embodiment 3

[0048] like Figure 5As shown, this embodiment provides an ignition rod automatic scraping device, including a lifting mechanism 100, an oxygen bullet fixing mechanism 101, and an ignition rod scraping mechanism 102 as in the first embodiment, wherein the oxygen bullet fixing mechanism 101 is used to fix the oxygen bullet, and the lifting mechanism 100 is used to drive the oxygen bullet fixing mechanism 101 to move up and down. In other embodiments, the ignition rod scraping mechanism 102 as in the second embodiment may also be used.

[0049] The fully automatic scraping device for the ignition rod in this embodiment is provided with a lifting mechanism 100 and an oxygen bullet fixing mechanism 101. When the ignition rod needs to be cleaned, the lifting mechanism 100 adjusts the oxygen bullet fixing mechanism 101 to a suitable height, fixes the oxygen bullet on the oxygen bullet fixing mechanism 101 by a manipulator, and the telescopic driving assembly 7 of the ignition rod scraping mechanism 102 drives the scraping assembly 2 to extend forward, and then the lifting mechanism 100 drives the oxygen bullet fixing mechanism 101 to descend and send the ignition rod into the scraping assembly 2 of the ignition rod scraping mechanism 102. While the scraping assembly 2 rotates, the lifting mechanism 100 drives the ignition rod to reciprocate up and down, and cleans the molten material on the ignition rod along the circumferential direction of the ignition rod and the axial direction of the ignition rod. When the molten material is scraped clean, the lifting mechanism 100 rises and drives the oxygen bullet fixing mechanism 101 to rise. The oxygen bullet fixing mechanism 101 is released, and the manipulator takes away the oxygen bullet to complete the ignition rod scraping work. No human intervention is required in the whole process, which can ensure that the molten material on the ignition rod is automatically cleaned and the ignition rod will not be damaged. It can effectively extend the service life of the ignition rod and meet the process requirements of automatic scraping of the unmanned testing system.

[0050] In this embodiment, an ash collecting mechanism 103 is further included. The ash collecting mechanism 103 is arranged below the ignition rod scraping mechanism 102. The ash collecting mechanism 103 collects the molten material scraped by the ignition rod scraping mechanism 102 to prevent the scraped molten material from spilling in the laboratory.

[0051] Compared with manual cleaning methods, the fully automatic scraping device for the ignition rod in this embodiment can realize automatic cleaning of the molten material on the ignition rod. When used in an unmanned testing system, there is no need to stop the experimental process when cleaning the ignition rod, which greatly improves the working efficiency of the entire system. The drive component 1 provides appropriate power, which can reliably scrape off the molten material on the ignition rod, and the flexible contact between the ignition rod and the scraping component 2 can ensure that the ignition rod will not be damaged during the automatic cleaning process.

[0052] The above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
