Description

Technical Field

[0001] This utility model relates to the field of high-temperature furnace technology, and in particular to a feeding device for a high-temperature experimental furnace. Background Technology

[0002] Experimental furnaces are heating devices used in laboratories, industrial and mining enterprises, and research institutions for elemental analysis and general heat treatment of small steel parts, such as quenching, annealing, and tempering. They can also be used for high-temperature heating of metals and ceramics, such as sintering, melting, and analysis. The heating elements of the experimental furnace are located on the four internal walls, which accelerates the temperature rise and ensures uniform heating. Therefore, experimental furnaces can also be used as heat treatment furnaces for small workpieces.

[0003] Most existing experimental furnaces place a boat-shaped crucible containing the sample inside the furnace and close the furnace door for high-temperature treatment. This method results in uneven heating of the crucible and sample, leading to low high-temperature treatment efficiency. Furthermore, this method requires workers to reach into the furnace with clamps to remove the crucible, which has a low safety factor. In addition, when the furnace door is opened, the hot inner wall of the furnace door is exposed to the vicinity of the experimental furnace, and users may be burned when they come into contact with the inner wall of the furnace door when removing the crucible.

[0004] Therefore, it is necessary to invent a high-temperature experimental furnace feeding device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature experimental furnace feeding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature experimental furnace feeding device, comprising a furnace base and a furnace body. The furnace body has a furnace door on its outer side, and a slidable base at its inner bottom. A support arm is fixedly mounted on the bottom of the furnace door, and the support arm has a ">" shaped structure. A support rod is fixedly mounted on the bottom of the support arm. A receiving groove is formed in the middle of the outer side of the furnace base, and a connecting groove is fixedly mounted at the top of the groove opening. Strip-shaped sliding grooves are formed on both inner walls of the receiving groove. Both ends of the support rod are slidably mounted... Within the two sliding grooves, a strip-shaped guide groove is provided at the bottom of the furnace body. A guide seat is fixedly provided in the middle of the lower surface of the base, and the guide seat is slidably disposed inside the guide groove. A movable seat is fixedly provided at the bottom of the guide seat. A through groove is provided through the bottom of the guide groove, and the movable seat is slidably disposed inside the through groove. An arc-shaped guide sleeve is fixedly provided in the middle of the outer wall of the furnace base, and the two ends of the guide sleeve are respectively connected to the through groove and the receiving groove. A chain is slidably provided inside the guide sleeve, and the two ends of the chain are respectively connected to the movable seat and the support rod.

[0007] Preferably, limiting rods are fixedly provided on both sides of the chain, and limiting grooves that are adapted to the limiting rods are provided on the inner walls of both sides of the through groove and the guide sleeve.

[0008] Preferably, a support shaft is fixedly provided in the middle of the inner sidewall of the support arm, an extension groove is provided at the bottom of the receiving groove, a slide seat is slidably provided inside the extension groove, and a transmission seat is fixedly provided at the top of the slide seat.

[0009] Preferably, the top of the transmission seat has an opening, and the inner diameter of the opening is slightly larger than the diameter of the support shaft.

[0010] Preferably, a hydraulic rod is fixedly provided at the bottom of the outer side wall of the furnace base, and the output shaft of the hydraulic rod is fixedly connected to the middle of the slide.

[0011] Preferably, the outer wall of the base is provided with an inclined surface, and the bottom end of the inner wall of the furnace body is provided with an inclined groove adapted to the inclined surface.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by setting up a furnace base, furnace body, furnace door, and base, allows products such as crucibles to be placed on the base inside the furnace body when heating them. When heating is complete and it is necessary to unload the product, the furnace door is flipped open and then pushed into the furnace base. During the process of pushing the furnace door in, the base is pushed outward, and the base pulls the crucibles and other products out. This achieves both furnace door storage and product unloading. Compared with the prior art, this technical solution not only facilitates the unloading of products such as crucibles, but also enables the storage of the furnace door to prevent users from being burned by the high temperature of the inner wall of the furnace door.

[0014] 2. This utility model, by setting up a guide sleeve, chain, support rod, slide block and hydraulic rod, allows the support rod at the bottom of the furnace door to engage with the opening of the slide block after the furnace door is opened. At this time, the hydraulic rod can drive the furnace door to move into the furnace base through the slide block to complete the storage. During this process, the furnace door pushes the base outward through the chain. The simultaneous driving of the furnace door and the base is achieved through a hydraulic rod, ensuring the synchronicity of the movement of the furnace door and the base, reducing the operation process of the device, and facilitating the material unloading work.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-6 The high-temperature experimental furnace feeding device shown includes a furnace base 1 and a furnace body 2. A furnace door 3 is provided on the outside of the furnace body 2. It should be noted that the furnace body 2 and the furnace door 3 in this embodiment adopt the existing structure in the prior art. The furnace body 2 can be set as one of a variety of types such as electric ceramic furnace and gas furnace. The furnace door 3 is provided with a corresponding handle and buckle structure.

[0024] The furnace body 2 has a sliding base 4 at the bottom of its interior. The furnace door 3 has a support arm 5 fixed at the bottom of its interior, and the support arm 5 has a ">" shaped structure. The support rod 6 is fixed at the bottom of the support arm 5. The furnace base 1 has a receiving groove 7 in the middle of its outer side. The top of the receiving groove 7 has a connecting groove 8 fixed at the top of the groove opening. The inner walls of both sides of the receiving groove 7 have strip-shaped sliding grooves 9. The two ends of the support rod 6 are slidably located in the two sliding grooves 9. The sliding grooves 9 can guide the movement of the support rod 6 to ensure that the furnace door 3 can slide stably into the receiving groove 7.

[0025] The furnace body 2 has a strip-shaped guide groove 10 at its bottom. The bottom surface of the base 4 is fixed with a guide seat 12, which is slidably disposed inside the guide groove 10. The bottom of the guide seat 12 is fixed with a movable seat 13. The bottom of the guide groove 10 is provided with a through groove 14. The movable seat 13 is slidably disposed inside the through groove 14. The outer side wall of the furnace base 1 is fixed with an arc-shaped guide sleeve 15. The two ends of the guide sleeve 15 are connected to the through groove 14 and the receiving groove 7, respectively. The inside of the guide sleeve 15 is slidably provided with a chain 16. The two ends of the chain 16 are connected to the movable seat 13 and the support rod 6, respectively. Limiting rods 17 are fixed on both sides of the chain 16. The inner walls of the through groove 14 and the guide sleeve 15 are provided with limiting grooves 18 that are adapted to the limiting rods 17. The limiting grooves 18 and the limiting rods 17 cooperate to prevent the chain 16 from bending and deforming during movement and causing movement interference.

[0026] A support shaft 19 is fixedly provided in the middle of the inner side wall of the support arm 5. The support shaft 19 is located in the middle of the ">" shaped structure of the support arm 5. When the support arm 5 rotates with the furnace door 3, the support shaft 19 is located below the furnace door 3, which can better connect with the transmission seat 22.

[0027] The bottom of the receiving groove 7 is provided with an extension groove 20. The inside of the extension groove 20 is provided with a slide block 21. The top of the slide block 21 is fixedly provided with a transmission seat 22. The top of the transmission seat 22 is provided with an opening, and the inner diameter of the opening is slightly larger than the diameter of the support shaft 19. The opening facilitates the insertion of the support shaft 19 into the transmission seat 22.

[0028] A hydraulic rod 23 is fixedly provided at the bottom of the outer side wall of the furnace base 1. The output shaft of the hydraulic rod 23 is fixedly connected to the middle of the slide 21. The hydraulic rod 23 is used to drive the slide 21 to move so as to realize the retraction and extension of the furnace door 3.

[0029] The outer side wall of the base 4 is provided with an inclined surface 11, and the bottom of the inner side wall of the furnace body 2 is provided with an inclined groove that matches the inclined surface 11. The inclined surface 11 can increase the contact area between the furnace body 2 and the base 4, thereby improving the sealing between them. It should be noted that the base 4 is made of heat insulation material, which can prevent the high temperature inside the furnace body 2 from affecting the structure below the base 4.

[0030] Working principle of this utility model:

[0031] In use, the crucible containing the product awaiting heating is placed on top of the base 4, which is located inside the furnace body 2. The furnace body 2 heats the crucible and other products through internal heating wires and other structures. When the product needs to be unloaded after heating, the user can open the furnace door 3 using the handle, causing the furnace door 3 to rotate around its bottom support rod 6 until it flips to a horizontal position. During this process, the furnace door 3 drives the support shaft 19 to rotate around the support rod 6 via the support arm 5. When the furnace door 3 flips to a horizontal position, the support shaft 19 rotates above the slide 21, at which point the control fluid... The pressure rod 23 drives the transmission seat 22 to slide horizontally. The transmission seat 22 drives the support shaft 19 to slide towards the inside of the furnace base 1. The support shaft 19 drives the furnace door 3 to slide into the receiving groove 7. During this process, the support rod 6 pushes one end of the chain 16, so that the chain 16 enters the guide sleeve 15. Under the guidance of the guide sleeve 15, the chain 16 slides along the through groove 14. One end of the chain 16 pushes the movable seat 13 to move, so that the movable seat 13 slides in the through groove 14. The movable seat 13 drives the base 4 to move, so that the base 4 slides out of the furnace body 2. The base 4 takes out the crucible and other products above it, thus completing the crucible unloading.

[0032] When loading products such as crucibles, place them directly on top of the base 4. Then, control the hydraulic rod 23 to drive the transmission seat 22 to slide outwards from the furnace base 1. The transmission seat 22 drives the support shaft 19 to slide, and the support shaft 19 drives the furnace door 3 to slide outwards from the furnace base 1. During this process, the support rod 6 pulls the chain 16, and the chain 16 pulls the base 4, causing the base 4 to slide into the interior of the furnace body 2. Then, close the furnace door 3 to complete the loading of the products.

[0033] It should be noted that during the transmission process between the furnace door 3 and the base 4, when the furnace door 3 pushes the chain 16, the limiting rods 17 on both sides of the chain 16 slide within the limiting grooves 18 as the chain 16 moves within the through groove 14. The portion of the chain 16 within the through groove 14 will not bend or deform. Similarly, when the chain 16 moves within the receiving groove 7, the limiting rods 17 at both ends of the chain 16 slide within the receiving groove 7, again preventing bending and deformation. This ensures the transmission stability of the chain 16. Furthermore, to ensure the transmission stability of the chain 16, a unidirectional bending structure is adopted. This structure is an existing technology and is used in products such as chain window openers. Since the chain 16 is only used as a transmission structure in this technical solution, it does not affect the implementation of the technical features of this solution.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
