A high temperature resistant tray

Abstract

The application provides a high-temperature-resistant tray, which comprises a heat-resistant disc and a taking-and-placing fork. The heat-resistant disc is provided with at least two through holes. The taking-and-placing fork comprises a fixing rod and a handle rod. The taking-and-placing fork is provided with at least two fixing rods. The fixing rod is matched with the through hole, so that the fixing rod can be inserted into the through hole. The rear ends of the plurality of fixing rods are connected and fixed through the handle rod. The fixing rod of the taking-and-placing fork can be made of elastic material. The difference between the interval of the plurality of fixing rods and the interval of the through holes is utilized, so that the normal pressure between the fixing rod and the inner wall of the through hole is generated. The static friction force between the taking-and-placing fork and the heat-resistant disc is generated by utilizing the normal pressure. The heat-resistant disc does not slip relative to the fixing rod, the crucible is stably transferred, and accidents such as the falling of the crucible are reduced. The high-temperature-resistant tray can be used in the return furnace and can be used in other crucible heating devices.

Description

Technical Field

[0001] This application relates to the field of auxiliary support devices, and more particularly to a high-temperature resistant pallet. Background Technology

[0002] When using a small precision annealing furnace to measure the loss on ignition of raw materials, four crucibles are typically required to minimize the impact of random errors. However, the internal space of the apparatus is limited, with the furnace chamber only about 10cm wide and the gaps between crucibles being very small. The provided crucible tongs have excessively large jaw contact surfaces, making them prone to collisions with the furnace wall and heating elements when holding the crucibles. This can obstruct operation and even cause equipment damage or crucible drops. Furthermore, high-temperature resistant gloves cannot be inserted into the small furnace chamber, further complicating daily operations. Therefore, it is necessary to design a high-temperature resistant tool or carrier that facilitates the movement of crucibles into and out of the equipment.

[0003] Chinese patent application CN210303738U, entitled "A Crucible Tray for Simultaneous Multi-Sample Measurement in a High-Temperature Environment," discloses a crucible tray capable of simultaneously measuring multiple samples in a high-temperature environment. The tray features four evenly distributed circular holes, upright supports on both sides, anti-tipping slots on both sides of the upper surface, and anti-slip grooves along the perpendicular central axes of the lower surface. This crucible tray facilitates the replacement of different crucibles in a high-temperature furnace, improving work efficiency and addressing technical issues such as damage to the furnace's insulation material due to drastic temperature drops during opening and closing. However, the tray requires a clamping structure for proper handling; slippage of the clamping surface can cause the crucible to wobble or even tip over. Utility Model Content

[0004] This application provides a high-temperature resistant tray to at least solve the problem of smooth crucible transfer technology in the prior art.

[0005] According to this application, a high-temperature resistant tray is provided, including a heat-resistant tray and a pick-up fork. The heat-resistant tray has at least two through holes. The pick-up fork includes a fixing rod and a handle rod. The pick-up fork has at least two fixing rods. The fixing rods are matched with the through holes so that the fixing rods can be inserted into the through holes. The rear ends of the multiple fixing rods are connected and fixed by the handle rod.

[0006] Compared with existing technologies, the high-temperature resistant pallet of this application has the following advantages: The fixing rods of the pick-and-place fork can be made of elastic material. By utilizing the difference between the spacing of multiple fixing rods and the spacing of the through holes, a frontal pressure is generated between the fixing rods and the inner wall of the through holes. This frontal pressure generates static friction between the pick-and-place fork and the heat-resistant plate, preventing the heat-resistant plate from slipping relative to the fixing rods. This ensures the smooth transfer of the crucible and reduces accidents such as crucible falling. It can be used not only in the return furnace but also in other applications that heat the crucible.

[0007] In one embodiment, a positioning head is provided at the front end of the fixing rod. The diameter of the positioning head is smaller than the diameter of the through hole but larger than the diameter of the fixing rod. When the fixing rod is tilted to one side, the positioning head deviates from the center position of the through hole. The step portion formed by the diameter difference of the positioning head can be used to abut against the end face of the through hole of the heat-resistant plate to achieve the limiting position.

[0008] In one embodiment, the heat-resistant plate is provided with multiple crucible slots, the size of which matches the bottom of the crucible so that the crucible can be placed on the crucible slot. This prevents the crucible from slipping when the heat-resistant plate is tilted.

[0009] In one embodiment, the fixing rod includes a left fixing rod and a right fixing rod, the rear ends of which are connected by a crossbar. The crossbar is equipped with a cam block, which rotates around the crossbar to move the heat-resistant plate. This makes it easier to remove the heat-resistant plate from the end of the fixing rod and avoids slow movement of the crucible during removal and placement.

[0010] In one embodiment, the cam block is provided with a control rod that extends backward and upward. In some annealing furnaces, the crucible needs to be placed in a deeper part of the annealing furnace. The backward extension of the control rod allows the heat-resistant plate to have more room to move.

[0011] In one embodiment, a handle is provided at the rear end of the fixed rod, and the handle extends backward and upward, so that the upper end of the handle is away from the annealing furnace, resulting in a lower temperature of the handle.

[0012] In one embodiment, the handle extends backward and upward from the rear end of the left fixed rod and then to the right. The handle extends to the rear and above the right fixed rod and then forward and downward to reach the right fixed rod. The upper end of the handle forms a U-shaped structure. The upper end of the control rod is provided with a flat rod. The flat rod and the control rod form a T-shaped structure. The flat rod is set close to the handle, so that the fingers can more easily control the flat rod.

[0013] In one embodiment, a support rod is provided at the rear end of the fixed rod, and the support rod is provided with a balance block. The balance block can balance the mass on both sides of the handle rod, making the crucible more stable during movement.

[0014] In one embodiment, the balancing block includes at least a first balancing block and a second balancing block. The mass of the first balancing block is the same as the mass of the heat-resistant plate. Thus, if the mass of the crucible is small, only the first balancing block can be used. If there is a large object in the crucible, the second balancing block needs to be used in combination. Multiple second balancing blocks can be provided.

[0015] In one embodiment, the first balance block has a first recess and the second balance block has a second protrusion. The first recess matches the second protrusion, so that the balance blocks are stacked more stably.

[0020] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Annealing furnaces and other heating furnaces all require the use of crucibles. There are situations where multiple crucibles need to be placed and removed at the same time. Due to the limited space in the furnace chamber, it is inconvenient to take out and place crucibles. Some crucibles can be placed with difficulty. In the narrow space, they may tilt or collide due to instability, which may result in sample spillage, experimental failure, or safety hazards (such as burns caused by hot crucibles tipping over).

[0022] like Figure 1 , Figure 2 and Figure 6 As shown, a high-temperature resistant tray includes a heat-resistant tray 1 and a pick-up fork 2. The heat-resistant tray 1 has at least two through holes 10. The pick-up fork 2 includes a fixing rod 21 and a handle rod 22. The pick-up fork 2 has at least two fixing rods 21. The fixing rods 21 are matched with the through holes 10 so that the fixing rods 21 can be inserted into the through holes 10. The rear ends of the multiple fixing rods 21 are connected and fixed through the handle rod 22. Figure 1 and Figure 2 In the assembled state, the fixing rod 21 is inserted into the through hole 10.

[0023] The heat-resistant plate 1 is designed according to the furnace boring size of the heating furnace. It is made of high-temperature resistant ceramic material, or it can be made of aluminum silicate fiber. It is lightweight and has an operating temperature range of 1000℃-1790℃. It can maintain good mechanical properties and stability at high temperatures.

[0024] The pick-and-place fork 2 is made of 310S stainless steel, which has strong oxidation resistance, a continuous operating temperature of up to 1150℃, a short-term temperature resistance of 1300℃, and good high-temperature strength and creep resistance.

[0025] Example 1: like Figure 6As shown, the fixing rod 21 is cylindrical, with a positioning head 23 at the front end. The positioning head 23 is a short cylinder or sphere with a diameter smaller than the diameter of the through hole 10 but larger than the diameter of the fixing rod 21. A square structure for the positioning head 23 would also have a similar function and be considered an equivalent design.

[0026] like Figure 7 As shown, in one embodiment, the heat-resistant plate 1 is provided with a plurality of crucible slots 11, the crucible slots 11 being sized to match the bottom of the crucible so that the crucible can be placed on the crucible slots 11. The crucible slots 11 can be designed as conical holes or as through conical hole structures.

[0027] like Figure 6 As shown, in one embodiment, the fixing rod 21 includes a left fixing rod 24 and a right fixing rod 25, which are arranged in parallel. The rear ends of the left fixing rod 24 and the right fixing rod 25 are connected by a crossbar 26. The left fixing rod 24 and the right fixing rod 25 are perpendicular to the crossbar 26. The crossbar 26 rotatably mounts a cam block 27. The cam block 27 can rotate around the crossbar 26 to push the heat-resistant disk 1 to move. To ensure the stability of the position of the cam block 27, a spring 20 is provided to limit the axial position and rotation angle of the cam block 27, and the spring 20 can be used to achieve reset.

[0028] like Figure 4 , Figure 5 and Figure 6 As shown, in one possible embodiment, the cam block 27 is provided with a control lever 28, which extends rearward and upward. The control lever 28 can extend rearward a certain distance before extending upward. Extending rearward can avoid the heating furnace restricting the angle when using the control lever 28 to rotate the cam block 27, thus preventing insufficient rotation.

[0029] like Figure 4 , Figure 5 and Figure 6 As shown, in one possible embodiment, a handle rod 22 is provided at the rear end of the fixed rod 21, and the handle rod 22 extends backward and upward.

[0030] like Figure 6 As shown, in one embodiment, the handle 22 extends backward and upward from the rear end of the left fixed rod 24 and then to the right. Alternatively, it can extend upward from the rear end of the left fixed rod 24 to a position flush with the control rod 28, then extend backward, upward, and then to the right. The handle 22 is symmetrically designed. After extending to the right fixed rod 25, the handle 22 extends forward and downward to reach the right fixed rod 25. The upper end of the handle 22 forms a U-shaped structure. The upper end of the control rod 28 is provided with a flat rod 29, which forms a T-shaped structure with the control rod 28. The flat rod 29 is positioned close to the handle 22. A D-shaped grip 30 can be provided at the upper end of the handle 22 for easy gripping.

[0031] like Figure 1 , Figure 2 and Figure 6 As shown, in one embodiment, a support rod 31 is provided at the rear end of the fixing rod 21, and a counterweight 3 is provided on the support rod 31. The support rod 31 can be formed into a circular ring structure, a square ring structure, or a mesh structure to facilitate the placement of the counterweight 3.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, in one possible embodiment, the balance block 3 includes at least a first balance block 32 and a second balance block 33, wherein the mass of the first balance block 32 is the same as the mass of the heat-resistant plate 1.

[0033] like Figure 1 , Figure 8 and Figure 9 As shown, in one embodiment, the first balancing block 32 has a first recess 34 at its upper end, and the second balancing block 33 has a second protrusion 35 at its lower end, with the first recess 34 matching the second protrusion 35. Since the support rod 31 has a square ring structure, both the first balancing block 32 and the second balancing block 33 are designed to be square. For ease of placement, the first balancing block 32 can have a raised layer 37 at its lower end to match the support rod 31, facilitating the restriction of the first balancing block 32's position using the support rod 31. The second balancing block 33 can have a second recess 36 at its upper end. The second balancing block 33 can be configured with multiple models of different sizes and masses, selected as needed.

[0034] like Figure 4 As shown, the control lever 28 is in its initial position at this time. The through hole 10 of the heat-resistant plate 1 is fitted onto the fixed lever 21, and the positioning head 23 is used to achieve the limiting position. That is, the fixed lever 21 can be tilted inward or outward at a certain angle so that the spacing of the positioning head 23 is different from the spacing of the through hole 10. In this way, after the fixed lever 21 is inserted into the through hole 10, it can be limited by the positioning head 23. Figure 5 As shown, to facilitate the removal of the heat-resistant plate 1, rotating the control lever 28 causes the cam block 27 to rotate forward, pushing the heat-resistant plate 1 forward, or pulling the fixing rod 21 backward, which causes the fixing rod 21 to move relative to the heat-resistant plate 1, thereby causing the fixing rod 21 to disengage from the heat-resistant plate 1.

[0035] Example 2: The furnace chamber is a cuboid 10cm wide, 10.5cm high, and 13.5cm deep, and the crucible is 4cm in diameter and 5cm high. Therefore, the designed heat-resistant plate 1 is a plate shaped like a plate with a length of 9cm, a width of 11cm, and a height of 2cm. Figure 10 As shown, the heat-resistant plate 1 is a rectangular block with two through holes 10. (As indicated...) Figure 11As shown, the pick-and-place fork 2 is equipped with two fixing rods 21. The fixing rods 21 can be inserted into the through hole 10 and are limited by the positioning head 23 set at the front end. The end of the pick-and-place fork 2 is provided with a D-shaped grip 30 for easy gripping. The fixing rods 21 can be extended upwards and then backwards.

[0036] The crucibles can be placed in an orderly manner on the heat-resistant plate 1. By utilizing the size of the heat-resistant plate 1, which is adapted to the narrow space of the furnace, the crucibles can be placed in the furnace indirectly, thus solving the problem of difficulty in conducting experiments due to insufficient space.

[0037] The pick-and-place fork 2, made of high-temperature resistant material, is inserted into the through hole 10 of the heat-resistant plate 1 to facilitate the quick and stable placement or removal of the heat-resistant plate 1 and crucible by the experimenter in the furnace, reducing operational errors caused by the confined space.

[0038] During operation, ensure that the heat-resistant plate 1 is free of cracks and deformation, and that there are no foreign objects in the bottom through-hole 10. Ensure that the placement fork 2 can be inserted smoothly. Place the crucible stably in the center of the heat-resistant plate 1, ensuring that the bottom of the crucible is completely in contact with the surface of the heat-resistant plate 1 without any gaps. If the crucible contains material, ensure that the material is evenly distributed and does not spill, to avoid tilting due to a shift in the center of gravity. Wearing high-temperature resistant gloves, hold the placement fork 2 with both hands and align it with the through-hole 10 of the heat-resistant plate 1. Slowly insert it horizontally (avoid tilting or applying force) to ensure that the fixing rod 21 is fully inserted into the through-hole 10 and in contact with the inner wall. Gently lift the tool to test its weight, ensuring that the heat-resistant plate 1 does not wobble or tilt before lifting it smoothly. After lifting, keep the fork horizontal and slowly move it to the target position. When placing it, first gently touch the heat-resistant plate 1 to the target platform to ensure stable contact. Use the protruding structure or the rod to restrict the position of the heat-resistant plate 1, and then slowly pull out the fixing rod 21. During the removal process, maintain a horizontal and uniform speed to avoid dragging the heat-resistant plate 1 and causing the crucible to shift.
