Description

Technical Field

[0001] This invention relates to the field of clamping device technology, and more specifically, to a fixing device for sheet-like and cylindrical specimens under high temperature and high pressure. Background Technology

[0002] Traditional techniques for fixing sheet-like and cylindrical specimens often involve clamping them with fixtures. However, these fixtures frequently experience insufficient or excessive clamping force. Insufficient clamping force can cause the workpiece to loosen, affecting processing quality, while excessive clamping force can deform or damage the workpiece or increase processing difficulty.

[0003] Furthermore, when the fixing device is located in the high temperature and high pressure environment of the reactor, it may fail, deform, or crack due to the high temperature and high pressure environment, causing the fixing device to be unable to maintain its original shape to fix the columnar and sheet-like samples. In the high temperature environment, traditional clamps may lose their clamping force due to their loose clamping and thermal expansion caused by the high temperature environment, thus failing to maintain the original position of the columnar and sheet-like samples and causing them to fall off. In the high pressure environment, traditional clamps may deform under pressure, and traditional clamps may be too tight, which may damage the columnar and sheet-like samples. Summary of the Invention

[0004] The problem solved by this invention is to provide a fixing device for sheet-like and cylindrical specimens under high temperature and high pressure, which can fix the cylindrical and sheet-like specimens while not being easily affected by the high pressure and high temperature environment, so that the cylindrical and sheet-like specimens can be stably fixed on the fixing device for a long time.

[0005] To address the above problems, the present invention provides a fixing device for sheet-like and cylindrical specimens under high temperature and high pressure, comprising:

[0006] A vertically arranged connecting rod and a horizontally arranged placement plate;

[0007] The placement tray is fixed on the connecting rod, and the upper surface of the placement tray has multiple first receiving slots of different sizes for embedding and placing sheet-shaped samples of different sizes.

[0008] The upper end of the connecting rod is fixed to the lower surface of the outer reactor lid, and the lower end is used to extend into the reactor. Multiple transverse placement channels are provided on the circumferential side wall of the connecting rod, which are used for inserting columnar samples.

[0009] The beneficial effects of the present application are that the vertical arrangement of the connecting rods can enable the connecting rods to be directly and vertically placed into the reactor when the reactor cover is connected to the reactor, and the horizontal arrangement of the placing disc can enable the disc to stably hold the sheet-shaped sample; the threaded arrangement on the outer circumferential wall of the columnar sample can enable the columnar sample to be locked in the placing hole by the nut, and the sample is not easy to fall off; the present application can fix the columnar sample and the sheet-shaped sample, and is not easy to be affected by the high-pressure and high-temperature environment, so that the columnar sample and the sheet-shaped sample can be stably fixed on the fixing device for a long time.

[0010] Further, the connecting rods are in the form of multiple split tubular structures; the diameters of all the connecting rods gradually decrease from top to bottom; the inner circumferential wall of the bottom of each connecting rod is provided with an internal thread, and the outer circumferential wall of each connecting rod is provided with an external thread matched with the internal thread, so that the connecting rods are integrally connected in sequence by the threads.

[0011] The beneficial effects of the arrangement are that the assembly is facilitated, and since the heights of the reactors can be different, the user can flexibly disassemble and assemble the connecting rods to adapt to reactors of different sizes.

[0012] Further, the placing disc is multiple, and each placing disc is vertically spaced and uniformly distributed along the connecting rod. The beneficial effects of the arrangement are that a larger number of sheet-shaped samples can be held.

[0013] Further, the placing disc is sleeved on the connecting rod, and a plurality of first nuts are threadedly connected to the connecting rod, and the first nuts are used to lock the upper and lower surfaces of each placing disc. The beneficial effects of the arrangement are that the placing disc is more firm and stable, and is not easy to be deformed or fall off due to the high-temperature and high-pressure extreme environment in the reactor.

[0014] Further, a rotating disc is coaxially arranged above or below each placing disc, the upper surface of the rotating disc is provided with a plurality of second accommodating grooves of different sizes for placing sheet-shaped samples of different sizes, and the center of each rotating disc is rotatably connected to the outer circumferential wall of the connecting rod by a bearing.

[0015] The beneficial effects of the arrangement are that the rotating disc can facilitate the user to select the second accommodating grooves of different sizes, and the use is more convenient.

[0016] Further, the upper surface of the rotating disc is further provided with a storage groove for storing objects. The beneficial effects of the arrangement are that the storage groove can store other objects, such as bolts and nuts needed during assembly, and the use is more convenient.

[0017] Further, a plurality of second nuts are threadedly connected on the connecting rod, and the second nuts are used for locking the lower surfaces of the rotating discs. The beneficial effect of the arrangement is that when the nuts are locked, the rotating discs are fixed and cannot rotate, and when the nuts are locked in the reaction kettle, the rotating discs are more stable in the high-temperature and high-pressure environment of the reaction kettle and are not prone to rotating and causing the sheet-shaped samples to fall off; when the nuts are loosened, the user can normally rotate the rotating discs.

[0018] Further, the number of the placing discs and the rotating discs are both even numbers, so that two rotating discs from top to bottom form a group; the two rotating discs in each group are fixedly connected with a connecting column arranged in the vertical direction, and the connecting column is arranged outside the placing disc.

[0019] The beneficial effect of the arrangement is that the connecting column can be held by the user to manually rotate the two rotating discs in each group, and the use is more convenient.

[0020] Further, screw holes are arranged on the circumferential outer edges of the first accommodating grooves and the second accommodating grooves on the two opposite sides. The beneficial effect of the arrangement is that corresponding screw holes can be arranged on the sheet-shaped samples, when the sheet-shaped samples are placed in the first accommodating grooves or the second accommodating grooves, bolts can be inserted into the screw holes and nuts can be screwed on the bolts, so that the sheet-shaped samples are locked and are not prone to falling out.

[0021] Further, the rotating disc is in a ring structure, and the inner ring of the rotating disc is fixedly connected with the bearing through a plurality of fixing rods arranged in the circumferential direction. The beneficial effect of the arrangement is that the weight of the rotating disc can be reduced, but the capacity of the rotating disc for containing sheet-shaped samples will be correspondingly reduced.

[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0030] In the description of the present application, it should be noted that the terms "upper", "lower", "left", "right", "front", "back" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the product is used, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0031] It should also be noted that in the following examples, when the sheet-shaped sample and the columnar sample are fixed by the nut, a gasket is required to be placed between the nut and the sheet-shaped sample or the columnar sample to protect the sheet-shaped sample or the columnar sample from being deformed when the nut is tightened; and the connecting rod 1 is a cylindrical rod structure.

[0032] The embodiment provides a fixing device for sheet-shaped samples and columnar samples in high temperature and high pressure, which comprises:

[0033] The connecting rod 1 is arranged in a vertical direction, and the putting disc 2 is arranged horizontally.

[0034] The putting disc 2 is fixed on the connecting rod 1, and a plurality of first containing grooves 21 of different sizes are formed on the upper surface of the putting disc 2, which are used for embedding different sizes of sheet-shaped samples.

[0035] The upper end of the connecting rod 1 is fixed on the lower surface of the external reactor cover body 100, and the lower end is used for extending into the reactor; a plurality of putting hole channels 11 are formed on the circumferential side wall of the connecting rod 1, which are used for inserting and placing the columnar sample.

[0036] Specifically, the length of the connecting rod 1 can be flexibly adjusted by those skilled in the art according to the height of the reactor. All placement channels 11 are evenly distributed along the length of the connecting rod 1, and the number of placement channels 11 can be flexibly adjusted by those skilled in the art according to the actual length of the connecting rod 1. The connecting rod 1 is set vertically, so that when the reactor lid 100 is attached to the reactor, the connecting rod can be directly and vertically placed into the reactor along the height of the reactor. The placement tray 2 is set horizontally so that it can stably hold the sheet-like sample. When the columnar sample is inserted into the placement channel 11, the columnar sample is locked in the opening of the placement channel 11 by the nut, so that it is not easy to fall off. This embodiment can fix the columnar sample and the sheet-like sample, and it is not easily affected by the high pressure and high temperature environment, so that the columnar sample and the sheet-like sample can be stably fixed on the fixing device for a long time.

[0037] In a preferred embodiment of the present invention, the connecting rod 1 is a multi-part tubular structure; the diameter of all connecting rods 1 gradually decreases from top to bottom; the inner peripheral wall of the bottom of each connecting rod 1 is provided with an internal thread, and the outer peripheral wall of each connecting rod 1 is provided with an external thread that mates with the internal thread, so that each connecting rod 1 is sequentially connected by threads to form a whole.

[0038] For details, see attached. Figure 1 As shown, each connecting rod 1 has a different diameter. When all connecting rods 1 are arranged coaxially vertically, the diameter of the connecting rods 1 decreases sequentially from top to bottom. This allows the upper end of the smaller diameter connecting rod 1 to be threaded onto the inner wall of the bottom of the larger diameter connecting rod 1. The multiple split tubular connecting rods 1 facilitate flexible assembly by the user. Since the height of the reactor may vary, the connecting rods 1 can be easily disassembled and assembled to adapt to reactors of different sizes. Threaded holes can be opened on the reactor cover 100 so that the threads on the outer peripheral wall of the uppermost connecting rod 1 can be threaded into the threaded holes on the reactor cover 100. In addition, the diameter of the placement channel 11 changes with the diameter of each connecting rod 1, that is, the diameter of the placement channel 11 on the smaller diameter connecting rod 1 is smaller than that on the larger diameter connecting rod 1, to accommodate columnar samples of different diameters. The diameter of the placement channel 11 on the same connecting rod 1 is the same, which can be used to place columnar samples of the same size.

[0039] In a preferred embodiment of the present invention, there are multiple placement trays 2, which are spaced apart and evenly distributed along the vertical axis of the connecting rod 1. (See attached diagram) Figure 1 As shown, multiple placement trays 2 can hold a large number of sheet-like samples.

[0040] In a preferred embodiment of the present invention, the placement disc 2 is sleeved on the connecting rod 1, and the connecting rod 1 is threaded with a plurality of first nuts, which are used to lock the upper and lower surfaces of each placement disc 2.

[0041] Specifically, the nut is screwed into the external thread on the outer peripheral wall of the connecting rod 1, which firmly fixes the placement plate 2 to the connecting rod 1, making the placement plate 2 more secure and stable, and less likely to deform or fall off due to the extreme environment of high temperature and high pressure inside the reactor.

[0042] In a preferred embodiment of the present invention, a rotating disk 3 is coaxially arranged above or below each placement disk 2. The upper surface of each rotating disk 3 is provided with multiple second receiving grooves 31 of different sizes for placing sheet-like samples of different sizes. The center of each rotating disk 3 is rotatably connected to the outer peripheral wall of the connecting rod 1 through a bearing 4.

[0043] Specifically, the rotating disk 3 and the corresponding placement disk 2 are spaced apart, so that the rotation of the rotating disk 3 will not affect the placement disk 2, and the spacing can ensure that the sample can be placed normally in the rotating disk 3 without being affected by the placement disk 2. The size and number of the second receiving groove 31 can be flexibly adjusted by those skilled in the art according to the actual situation. A through hole is provided at the center of the rotating disk 3. The through hole is used to fix the bearing 4 and pass through the connecting rod 1 to form a rotational connection with the outer peripheral wall of the connecting rod 1. The bearing 4 is a deep groove ball bearing. The rotating disk 3 can be easily rotated by the user to select different sizes of the second receiving groove 31, making it more convenient to use. It should be noted that since the outer peripheral wall of the connecting rod 1 is provided with threads, the connection between the connecting rod 1 and the bearing 4 needs to be treated to match the bearing 4. Since the bearing 4 is a deep groove ball bearing, the peripheral wall of the inner ring of the deep groove ball bearing can be fixedly connected to the outer peripheral wall of the connecting rod 1.

[0044] In a preferred embodiment of the present invention, the upper surface of the rotating disk 3 is further provided with a storage groove 32 for placing items.

[0045] For details, see attached. Figure 3 As shown, the upper surface of the rotating disk 3 needs a certain space for opening the storage slot 32. The storage slot 32 and the second receiving slot 31 do not interfere with each other. The storage slot 32 can be used to hold items such as nuts and bolts needed during assembly, which is convenient for users.

[0046] In a preferred embodiment of the present invention, a plurality of second nuts are threaded onto the connecting rod 1, and the second nuts are used to lock the lower surface of each rotating disk 3.

[0047] For details, see attached. Figure 1 As shown, when the nut is tightened, the rotating disk 3 can be fixed and cannot rotate. The user can choose to tighten the nut when the connecting rod 1 is inserted into the reactor, so that the rotating disk 3 is not easy to rotate randomly in the high temperature and high pressure environment in the reactor, thereby preventing the sheet sample from being thrown out due to rotation.

[0048] In a preferred embodiment of the present invention, the number of placement disks 2 and rotating disks 3 are both even, so that two rotating disks 3 from top to bottom form a group; a connecting post 33 arranged in the vertical direction is fixedly connected between the two rotating disks 3 in each group, and the connecting post 33 is arranged on the outside of the placement disk 2.

[0049] For details, see attached. Figure 1 As shown, there are four placement disks 2 and four rotating disks 3. Each pair of rotating disks 3 forms a group from top to bottom, and the connecting post 33 is attached. Figure 1 As shown in the diagram, the vertically arranged connecting post 33 allows the user to hold and rotate the upper and lower rotating disks 3 in each group, making it more convenient to use. It should be noted that the connecting post 33 is located outside the placement disk 2 without affecting the placement disk 2. Here, "located outside the placement disk 2" means that the distance between the two connecting posts 33 is greater than the length of the placement disk 2.

[0050] In a preferred embodiment of the present invention, screw holes 12 are provided on both sides of the circumferential outer edge of each first receiving groove 21 and second receiving groove 31 in opposite directions.

[0051] For details, see attached. Figure 2 To be continued Figure 4 As shown, screw holes 12 are provided on both sides of each first receiving groove 21 and second receiving groove 31 in opposite directions, and corresponding screw holes are also provided on the sheet sample, so that when the sheet sample is placed in the first receiving groove 21 or the second receiving groove 31, bolts can be inserted into the screw holes and screwed in with nuts, so that the sheet sample is firmly fixed in the first receiving groove 21 or the second receiving groove 31 and is not easy to fall out.

[0052] In a preferred embodiment of the present invention, the rotating disk 3 has an annular structure, and the inner ring of the rotating disk 3 is fixedly connected to the bearing 4 by multiple fixed rods 34 distributed circumferentially.

[0053] For details, see attached. Figure 3 Or attached Figure 4 As shown, the rotating disk 3 has an annular structure, and the second receiving groove 31 is opened on the circumferential surface of the rotating disk 3. The annular structure of the rotating disk 3 can save materials and make the rotating disk 3 lighter. However, due to the reduction in area, the second receiving groove 31 will be reduced accordingly, which will reduce the capacity of the sheet sample. Those skilled in the art can make flexible choices according to the actual situation. The inner ring of the rotating disk 3 is fixedly connected to the bearing 4 by four fixing rods 34, and the four fixing rods 34 are in a cross structure.

[0054] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited to this. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present disclosure.
