Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, in particular to an asbestos ashing tray. Background Art

[0002] Asbestos materials were once widely used in shipbuilding, but with the deepening of the understanding of the carcinogenicity of asbestos, the use of asbestos materials in shipbuilding has begun to be banned at this stage. However, since some materials are still mixed with asbestos, the materials need to be ashed.

[0003] The current practice is to put the material into a crucible and then place the crucible directly into a box-type electric furnace. However, due to the limited internal space of the box-type electric furnace, the scattered crucibles are unevenly distributed in the furnace, which wastes the space in the furnace. The process of taking and placing the crucibles also needs to be done one by one, which greatly reduces the operating efficiency.

[0004] Therefore, it is urgent to provide an asbestos ashing tray to solve the problems in the prior art to a certain extent. Summary of the invention

[0005] The purpose of the present invention is to provide an asbestos ashing tray, so as to solve the technical problem that the crucibles used for asbestos ashing are randomly placed in the furnace body during detection, resulting in a time-consuming and laborious removal process.

[0006] An asbestos ashing tray provided by the present invention comprises a tray assembly, wherein a plurality of accommodating portions are formed on the tray assembly, and the plurality of accommodating portions are arranged in an array, wherein the number of accommodating portions in the middle row of the tray assembly is less than the number of accommodating portions in the two side rows, and the difference is one, so as to form an avoidance area on the tray assembly.

[0007] Among them, the tray assembly includes a positioning tray and a carrying tray; the positioning tray and the carrying tray are overlapped, and the positioning tray is located on the carrying tray; a plurality of positioning through holes are formed on the positioning tray, and a receiving groove is formed on the carrying tray at positions corresponding to the positioning through holes. When the positioning tray is placed on the carrying tray, the positioning through holes and the receiving grooves are relatively positioned to form the receiving portion.

[0008] Specifically, a plurality of connecting posts are disposed on the carrying tray, and connecting through holes are formed on the positioning tray at positions corresponding to the connecting posts, and one end of the connecting post can pass through the connecting through hole to align the positioning tray with the carrying tray.

[0009] Furthermore, the height of the connecting column is greater than the thickness of the positioning tray, so that one end of the connecting column protrudes from a side of the positioning tray away from the carrying tray.

[0010] Furthermore, the asbestos ashing tray provided by the present invention further includes a positioning member. A pin hole is formed at one end of the connecting column protruding from the positioning tray, and the positioning member is driven into the pin hole to detachably connect the bearing tray and the positioning tray.

[0011] Furthermore, the asbestos ashing tray provided by the present invention further includes a nut. A thread is formed on the outer wall surface of one end of the connecting column protruding from the positioning tray, and the nut is threadedly connected to the connecting column to lock the positioning tray and the bearing tray.

[0012] Wherein, a limiting member is provided on one side of the positioning tray facing away from the bearing tray, and the limiting member is arranged in one-to-one correspondence with the positioning through hole; the limiting member includes a telescopic portion and a limiting portion. The telescopic portion can telescopically move in the vertical direction, and the limiting portion can rotate relative to the telescopic portion.

[0013] Specifically, the limiting member is made of a high-temperature resistant alloy material, and the limiting member further includes a universal ball head. One end of the telescopic portion away from the positioning tray is connected to one end of the limiting portion through the universal ball head, and a limiting ring is formed at one end of the limiting portion away from the universal ball head.

[0014] Further, a plurality of supporting convex portions are formed on one side of the positioning tray facing the bearing tray, and a mating concave portion is formed at a position corresponding to the supporting convex portion on the bearing tray, and the supporting convex portion can be inserted into the mating concave portion.

[0015] Furthermore, a clamping portion is formed on the positioning tray, and the clamping portion is located at both ends of the accommodating portion in the middle column; a first gripping portion is provided on the front side arm of the positioning tray, and second gripping portions are provided on the side walls on both sides of the bearing tray.

[0016] Compared with the prior art, the asbestos ashing tray provided by the present invention has the following advantages:

[0017] The asbestos ashing tray provided by the present invention includes a tray assembly. A plurality of accommodating portions are formed on the tray assembly, and the plurality of accommodating portions are arranged in an array. The number of accommodating portions in the middle column of the tray assembly is less than the number of accommodating portions in the two side columns, and the difference is one, so as to form an avoidance area on the tray assembly.

[0018] From the above analysis, it can be seen that through the plurality of accommodating portions formed on the tray assembly, crucibles for asbestos ashing detection can be placed. Since the accommodating portions in the present application are arranged in an array, the set space on the tray assembly can be maximally utilized to form the accommodating portions, so that the tray assembly has a greater bearing capacity.

[0019] Since temperature probes are provided inside all existing experimental furnaces for asbestos ashing, in order to avoid the tray assembly from touching the temperature probes during the process of carrying the crucible into the experimental furnace, in this application, the number of accommodating parts in the middle column of the tray assembly is one less than the number of accommodating parts on both sides, so as to form an avoidance area on the tray assembly, thereby being able to avoid the temperature probes and enabling the tray assembly to smoothly extend into the experimental furnace for asbestos ashing detection.

[0034] Example 1

[0035] As Figures 1-3 shown, the present invention provides an asbestos ashing tray, including a tray assembly. A plurality of accommodating portions are formed on the tray assembly, and the plurality of accommodating portions are arranged in an array. The number of accommodating portions in the middle column of the tray assembly is less than the number of accommodating portions in the two side columns, and the difference is one, so as to form an avoidance area on the tray assembly.

[0036] Compared with the prior art, the asbestos ashing tray provided by the present invention has the following advantages:

[0037] The asbestos ashing tray provided by the present invention can place crucibles for asbestos ashing detection through a plurality of accommodating portions formed on the tray assembly. Since the accommodating portions in this application are arranged in an array, the set space on the tray assembly can be utilized to the maximum extent to form the accommodating portions, so that the tray assembly has a greater bearing capacity.

[0038] Since temperature probes are provided inside existing experimental furnaces for asbestos ashing, in order to avoid the tray assembly carrying the crucible from touching the temperature probe during the process of being sent into the experimental furnace, in this application, by making the number of accommodating portions in the middle column of the tray assembly one less than the number of accommodating portions on both sides, an avoidance area can be formed on the tray assembly, so as to avoid the temperature probe and enable the tray assembly to smoothly extend into the experimental furnace for asbestos ashing detection.

[0039] It can be understood that the tray assembly in this application is made of high-temperature resistant materials, which can be heat-resistant steel, tungsten-cobalt alloy or other high-temperature resistant alloy materials, or can also be materials such as ceramics or clay. Preferably, the tray assembly in this application is made of clay, which can not only ensure the bearing of the crucible, but also reduce the manufacturing cost of the overall structure to a certain extent.

[0040] It should be supplemented here that, asFigure 1 As shown, preferably, the number of positioning parts in this application is 11, and the number of positioning parts on both sides is four, and the number of positioning parts in the middle column is three, so as to form an avoidance area on the tray assembly to prevent the tray assembly from touching the temperature probe after carrying the crucible and being sent into the furnace body, resulting in damage to the temperature probe.

[0041] The number of positioning parts in this application being 11 is only one of the implementation manners, and arranging them in the above-mentioned array can also ensure the overall uniform force of the tray assembly to a certain extent and improve the service life of the tray assembly. The specific number and arrangement of the positioning parts can also be designed according to specific requirements, which will not be elaborated here.

[0042] Embodiment 2

[0043] Based on the above implementation manner, this application further optimizes the structure of the tray assembly. In this implementation manner and the following implementation manners, as Figure 1 shown, the tray assembly includes a positioning tray 1 and a carrying tray 2; the positioning tray 1 and the carrying tray 2 are overlapped, and the positioning tray 1 is located on the carrying tray 2; a plurality of positioning through holes 101 are formed on the positioning tray 1, and accommodation grooves 201 are formed at positions corresponding to the positioning through holes 101 on the carrying tray 2. When the positioning tray 1 is placed on the carrying tray 2, the positioning through holes 101 and the accommodation grooves 201 are aligned to form an accommodation part.

[0044] In this implementation manner, the carrying tray 2 and the positioning tray 1 are of a split structure. The positioning through holes 101 are formed on the positioning tray 1. When the crucible is placed into the positioning through holes 101 of the positioning tray 1, the bottom of the crucible can pass through the positioning through holes 101. Since the positioning tray 1 is located above the carrying tray 2 and the positioning tray 1 and the carrying tray 2 are overlapped, the bottom of the crucible can enter the accommodation grooves 201 formed at positions corresponding to the positioning through holes 101 of the carrying tray 2, realizing the carrying of the crucible.

[0045] The positioning through holes 101 in this application can be cylindrical through holes or inverted frustum-shaped through holes.

[0046] When the positioning through holes 101 are inverted frustum-shaped through holes, preferably, the maximum diameter of the positioning through holes 101 is smaller than the maximum diameter of the crucible, and the diameter of the inverted frustum-shaped through hole on the side of the positioning through hole 101 away from the carrying tray 2 is larger than the diameter on the side close to the carrying tray 2. Thus, when the crucible is placed into the positioning through holes 101, the crucible can be in contact with the positioning through holes 101 of the positioning tray 1, that is, when the positioning tray 1 is lifted in the direction away from the carrying tray 2, the crucible can be lifted together, and then the positioning tray 1 can be used alone.

[0047] During use, first place the crucible into the corresponding positioning through-hole 101. Then, the operator lifts the positioning tray 1, and the crucible drops until the outer wall surface of the crucible abuts against the inner wall of the positioning through-hole 101. After being sent into the furnace body, the bottom of the crucible is always in contact with the bottom wall of the furnace body. The positioning tray 1 moves relative to the crucible until it drops to contact the bottom wall inside the furnace body, completing the feeding of the crucible.

[0048] After the ashing is completed, pull the positioning tray 1, thereby driving all the crucibles to move along with the positioning tray 1. After the positioning tray 1 moves out of the furnace body, the crucible hangs and moves downward relative to the positioning tray 1 and is stuck in the positioning through-hole 101 again, completing the removal of the crucible. It can be understood that the frustum-shaped positioning through-hole 101 can make the outer wall of the crucible fit better with it, improving the stability during movement.

[0049] When the positioning through-hole 101 is a cylindrical through-hole, the maximum diameter of the positioning through-hole 101 is greater than the maximum diameter of the crucible. In this solution, the positioning tray 1 needs to be used in cooperation with the bearing tray 2. Therefore, it can be understood that when the above structure is used for ashing operations, one positioning tray 1 can be paired with two bearing trays 2. After one ashing operation is completed, the positioning tray 1 and the bearing tray 2 are taken out and placed on the corresponding platform at the same time. Since the diameter of the positioning through-hole 101 is greater than the diameter of the crucible, the positioning tray 1 can be directly separated from the bearing tray 2. Then, the positioning tray 1 is docked with another bearing tray 2, and the crucible is placed and sent into the furnace body for continued detection. After the crucible in the previous stage dissipates heat and cools on the platform, observe the internal ashing situation, thereby being able to improve the detection efficiency to a certain extent and save detection time.

[0050] Since the bottom of the crucible will rub against the bottom wall of the furnace body during the process of the positioning tray 1 being sent into and taken out of the furnace body alone, preferably, the positioning tray 1 and the bearing tray 2 are used simultaneously. During movement, lift the bearing tray 2 and move the positioning tray 1 and the crucible inside the positioning part at the same time. Only the bottom of the bearing tray 2 contacts the bottom wall of the furnace body during the process of entering and exiting the furnace body.

[0051] Preferably, as Figure 1 Combined Figure 3 shown, the bearing tray 2 in the present application is provided with a plurality of connecting columns 202, and connection through-holes 103 are formed at the positions of the positioning tray 1 corresponding to the connecting columns 202. One end of the connecting column 202 can pass through the connection through-hole 103 to align the positioning tray 1 and the bearing tray 2.

[0052] Since the positioning tray 1 and the carrying tray 2 are split structures, and the positioning portion is formed by the positioning through hole 101 and the receiving groove 201, it is necessary to accurately position the positioning tray 1 and the carrying tray 2. The present application provides a connecting post 202 on the carrying tray 2, and provides a connecting through hole 103 on the positioning tray 1 at a position corresponding to the connecting post 202, so that the connecting post 202 passes through the connecting through hole 103, thereby realizing the positioning and connection of the positioning tray 1 and the carrying tray 2.

[0053] It is necessary to add that, if Figure 1 Combination Figure 3 As shown, preferably, the number of the connecting posts 202 in the present application is two, and they are located on both sides of the most central receiving groove 201, which can avoid the problem of contact with the temperature probe in the furnace body on the basis of realizing the alignment connection between the positioning tray 1 and the carrying tray 2. The number and position of the connecting posts 202 are only one of the implementation methods, and a larger number of connecting posts 202 can also be set, but it must be considered that the connecting posts 202 will be deformed under high temperature conditions in the furnace body, resulting in the problem that the connecting posts 202 and the connecting through holes 103 cannot be accurately aligned after long-term use.

[0054] It is understandable that since the connecting column 202 is prone to collide with the positioning tray 1 during docking, in order to ensure the strength of the connecting column 202, the connecting column 202 in the present application is made of high-temperature resistant materials, such as heat-resistant steel and other metal or alloy materials, which can also reduce the deformation to a certain extent and improve the alignment accuracy.

[0055] Further preferably, in the present application, the height of the connecting post 202 is greater than the thickness of the positioning tray 1 , so that one end of the connecting post 202 protrudes from the side of the positioning tray 1 away from the carrying tray 2 .

[0056] Since in the above scheme, no corresponding connection and locking structure is provided between the positioning tray 1 and the carrying tray 2, the positioning tray 1 and the carrying tray 2 are in an active connection state. To ensure that the positioning tray 1 and the carrying tray 2 do not separate during movement, the present application facilitates processing of the end of the connecting column 202 by making one end of the connecting column 202 protrude from the side of the positioning tray 1 away from the carrying tray 2, thereby realizing a locking connection between the positioning tray 1 and the carrying tray 2.

[0057] Therefore, the present application provides two connection methods that can lock the positioning tray 1 and the carrying tray 2.

[0058] In one embodiment, the asbestos ashing tray provided in the present application further includes a positioning member, and a connecting column 202 protrudes from one end of the positioning tray 1 and is provided with a pin hole 2021 , and the positioning member is driven into the pin hole 2021 to enable the carrying tray 2 to be detachably connected to the positioning tray 1 .

[0059] In this embodiment, the positioning member is a pin shaft, a pin or a pin piece. After being driven into the pin hole 2021, the locking connection between the positioning tray 1 and the bearing tray 2 can be quickly realized. When it is necessary to separate the positioning tray 1 from the bearing tray 2, only by pulling out the positioning member can the quick separation between the positioning tray 1 and the bearing tray 2 be achieved.

[0060] In another way, the asbestos ashing tray provided by the present invention further includes a nut. A thread is formed on the outer wall surface of the end of the connecting column 202 protruding from the positioning tray 1, and the nut is threadedly connected to the connecting column 202 to lock the positioning tray 1 and the bearing tray 2.

[0061] By machining a thread at the end of the connecting column 202 and screwing in the nut, the stable connection between the positioning tray 1 and the bearing tray 2 can be realized. Even if the positioning tray 1 is lifted, the bearing tray 2 will not be separated from the positioning tray 1. When it is necessary to separate the positioning tray 1 from the bearing tray 2, only by screwing out the nut can the separation of the two structures be achieved.

[0062] Embodiment 3

[0063] Based on the above structure, as Figure 1 Combined with Figure 2 shown, the present application further optimizes the structure of the positioning tray 1. A limiting member 104 is provided on the side of the positioning tray 1 facing away from the bearing tray 2, and the limiting member 104 is arranged in one-to-one correspondence with the positioning through hole 101; the limiting member 104 includes a telescopic part 1041 and a limiting part 1042. The telescopic part 1041 can telescopically move in the vertical direction, and the limiting part 1042 can rotate relative to the telescopic part 1041.

[0064] Since the crucible mainly includes a main body and a cover body, when testing, after the material is placed in the main body, the cover body needs to be covered and sent into the furnace. In order to avoid damage to the crucible caused by the separation and dropping of the cover body from the main body during the moving process, a limiting member 104 is installed on the positioning tray 1 in the present application. After the crucible is placed in the corresponding accommodating part, the limiting member 104 at the corresponding position limits the cover body, so as to avoid the problem of the separation of the cover body from the main body.

[0065] Since the limiting member 104 in the present application includes a telescopic part 1041 and a limiting part 1042, and the telescopic part 1041 can telescopically move in the vertical direction and the limiting part 1042 can rotate relative to the telescopic part 1041, therefore, after the crucible is placed in the accommodating part, the limiting part 1042 is rotated above the cover body, and by pressing down the telescopic part 1041, the telescopic part 1041 contracts, so that the limiting part 1042 can press on the cover body to realize the limitation of the cover body.

[0066] It can be understood that the telescopic part 1041 in the present application is a telescopic rod, and the contact force between the limiting part 1042 and the cover body can be adjusted by telescoping, so as to realize the limitation of the cover body. And in the present application, by rotatably connecting the limiting part 1042 with the telescopic part 1041, the problem that the limiting part 1042 interferes with the process of putting or taking out the crucible from the accommodating part can be avoided.

[0067] Preferably, the limiting member 104 in the present application is made of a high-temperature resistant alloy material, and as Figure 1 shown in combination with Figure 2 the limiting member 104 in the present application further includes a universal ball head 1043. One end of the telescopic part 1041 far from the positioning tray 1 is connected to one end of the limiting part 1042 through the universal ball head 1043, and a limiting ring 1044 is formed at one end of the limiting part 1042 far from the universal ball head 1043.

[0068] In the present application, by connecting the limiting part 1042 and the telescopic part 1041 through the universal ball head 1043, the limiting part 1042 can rotate at multiple angles relative to the telescopic part 1041, so as to avoid the limiting part 1042 affecting the process of putting or taking out the crucible from the accommodating part.

[0069] Since an end cap for holding is formed on the cover body, therefore, in the present application, a limiting ring 1044 is formed at one end of the limiting part 1042 far from the telescopic part 1041, and the diameter of the limiting ring 1044 is greater than the diameter of the end cap, so that the limiting ring 1044 can be sleeved on the end cap to realize the pressing of the cover body.

[0070] Optionally, as Figure 1 shown, a plurality of supporting convex parts 106 are formed on one side of the positioning tray 1 facing the bearing tray 2, a matching concave part 203 is formed at the position of the bearing tray 2 corresponding to the supporting convex parts 106, and the supporting convex parts 106 can be inserted into the matching concave part 203.

[0071] Through the insertion of the supporting convex parts 106 and the matching concave parts 203, the alignment stability between the bearing tray 2 and the positioning tray 1 can be further improved, and when the positioning tray 1 is used alone, it can be used as a supporting structure for the positioning tray 1 to ensure the levelness of the positioning tray 1.

[0072] Optionally, as Figure 1 shown, a clamping part 102 is formed on the positioning tray 1, and the clamping part 102 is located at both ends of the middle row of accommodating parts; a first holding part 105 is provided on the front side arm of the positioning tray 1, and second holding parts 204 are provided on the side walls on both sides of the bearing tray 2.

[0073] The clamping part 102 in this application can be an oblong hole or an oblong groove, and the number of the clamping parts 102 is two, which are oppositely arranged at both ends of the positioning tray 1, so as to facilitate the clamping by the fixture.

[0074] Furthermore, through the first holding part 105 arranged on the side wall of the positioning tray 1, when taking out the tray assembly from the furnace body, it is convenient for the operator to hold, so that the tray assembly can be pulled out.

[0075] By arranging the second holding parts 204 on both sides of the carrying tray 2, it is convenient for the operator to lift the carrying tray 2, so as to realize the stable movement of the overall tray assembly.

[0076] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
