Description

Technical Field

[0001] The utility model relates to the field of crucibles, in particular to a crucible cover and a crucible. Background Art

[0002] A crucible is a melting pot made of extremely refractory materials, such as clay, porcelain clay and other difficult-to-melt metals. Crucibles are mainly used to melt metals or other substances. During use, the crucible is used in conjunction with a crucible cover, which covers the top of the crucible and effectively protects the contents of the crucible from external influences.

[0003] However, most crucibles currently available on the market require the crucible lid to be opened for charging and then closed during use. The process of opening the crucible lid takes a long time, causing the raw materials inside the crucible to be exposed to the outside air for a long time, which accelerates the oxidation reaction and reduces the smelting effect. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the shortcomings of the existing technology, the utility model provides a crucible cover and a crucible, which have the advantages of shortening the time of opening the crucible cover when adding materials in the middle, slowing down the oxidation reaction of the molten raw materials, and improving the smelting effect. It solves the problem that the time of opening the crucible cover is long, so that the raw materials inside the crucible are in contact with the outside air for a long time, which accelerates the oxidation reaction and reduces the smelting effect.

[0006] (2) Technical solution

[0007] In order to achieve the purpose of shortening the time of opening the crucible cover when adding materials in the middle, slowing down the oxidation reaction of the molten raw materials, and improving the smelting effect, the utility model provides the following technical solutions: a crucible cover and a crucible, comprising a crucible pot body and a crucible cover body, the top of the crucible cover body is fixedly connected to an auxiliary pull ring, the bottom of the crucible cover body is fixedly connected to a limiting frame, the front of the crucible cover body is provided with a feed trough, and the inner bottom wall of the feed trough is provided with a feed channel.

[0008] The inner top wall of the feed trough is provided with a feed port, the inner bottom wall of the feed trough is fixedly connected with a second spring, the top of the second spring is fixedly connected with a blocking plate, and the bottom of the blocking plate is provided with an exhaust hole. The raw materials are directly placed into the feed port through the provided crucible pot body, crucible cover body, feed port and blocking plate. The blocking plate will move downward after being subjected to the gravity of the raw materials, and the raw materials can enter the interior of the crucible pot body through the feed channel. After the raw materials are separated from the blocking plate, the elastic force of the second spring will drive the blocking plate to move upward to the position of the raw materials, and then the blocking plate can immediately block the feed port, thereby shortening the time to open the crucible cover body when adding materials in the middle of the device, and shortening the time that the raw materials inside the crucible pot body are in contact with the air, slowing down the oxidation reaction of the molten raw materials, and improving the smelting effect.

[0009] As a preferred technical solution of the present invention, the shape of the limiting frame is a "rectangular frame" structure. The setting of the limiting frame facilitates the limiting function of the crucible cover.

[0010] As an optimal technical solution of the present invention, the outer wall of the blocking plate is an inclined surface, the outer wall of the blocking plate is slidingly connected to the inner wall of the feed trough, and the bottom of the blocking plate is fixedly connected with a telescopic rod. Through the provision of the telescopic rod, the blocking plate will not be skewed when moving.

[0011] As an optimal technical solution of the present invention, the telescopic rod is movably connected to the second spring, and the bottom of the telescopic rod is fixedly connected to the inner bottom wall of the feed trough. Through the provision of the second spring, the blocking plate can be reset by the elastic force of the second spring after being free from the action of force.

[0012] As an optimal technical solution of the present invention, a groove is provided on the outer wall of the crucible pot body, a first spring is fixedly connected to the inner side wall of the groove, a moving block is fixedly connected to one end of the first spring, a limiting block is fixedly connected to the top of the moving block, the inner wall of the limiting frame is slidably connected to the outer wall of the limiting block, and the limiting block can be set to limit the limiting frame.

[0013] As an optimal technical solution of the present invention, the shape of the limit block is a "right-angled trapezoid" structure, the outer wall of the limit block is slidingly connected to the inner wall of the groove, the outer wall of the moving block is slidingly connected to the inner wall of the groove, and a moving plate is fixedly connected to one side of the moving block. The moving plate is set to facilitate the movement of the moving block and the limit block to the inside of the groove.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present invention provides a crucible cover and a crucible, which have the following beneficial effects:

[0016] 1. By setting the crucible pot body, crucible cover body, feed port and blocking plate, the raw materials can be directly placed into the feed port. The blocking plate will move downward under the gravity of the raw materials, and the raw materials can enter the crucible pot body through the feed channel. After the raw materials are separated from the blocking plate, the elastic force of the second spring will drive the blocking plate to move upward to the position of the raw materials, and then the blocking plate can immediately block the feed port, thereby shortening the time of opening the crucible cover body when adding materials in the middle of the device, and shortening the time that the raw materials inside the crucible pot body are in contact with the air, slowing down the oxidation reaction of the molten raw materials, and improving the smelting effect.

[0017] 2. By providing the crucible cover, the limiting frame and the limiting block, and using an external auxiliary clamp tool to clamp the movable plate, the movable block and the limiting block can be moved toward the inside of the groove, thereby separating the limiting block from the limiting frame, and the crucible cover is no longer restricted, so that the crucible cover can be disassembled and the raw materials inside the crucible pot can be discharged, thereby further meeting the use requirements of the device, thereby providing an effective auxiliary effect to the device, and thus worthy of promotion.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1-4, which is the first embodiment of the present utility model, provides a crucible cover and crucible, including a crucible pot body 1 and a crucible cover body 2. The top of the crucible cover body 2 is fixedly connected with an auxiliary pull ring 3, which can be used to more conveniently remove the crucible cover body 2 from the crucible pot body 1. The bottom of the crucible cover body 2 is fixedly connected with a limiting frame 4. A feeding groove 10 is provided on the front of the crucible cover body 2, and a feeding channel 11 is provided on the inner bottom wall of the feeding groove 10. When adding materials in the middle, raw materials can be added through the feeding channel 11.

[0026] A feed port 12 is provided on the inner top wall of the feed trough 10, and a second spring 13 is fixedly connected to the inner bottom wall of the feed trough 10. A blocking plate 14 is fixedly connected to the top of the second spring 13. After the raw material presses down the blocking plate 14, it can enter the interior of the crucible pot body 1 through the feed channel 11. The blocking plate 14 can be reset by the elastic force of the second spring 13 after being free from the force. An exhaust hole 15 is provided at the bottom of the blocking plate 14, and the top of the blocking plate 14 blocks the feed port 12, so that the gas outside the crucible pot body 1 will not enter the interior of the crucible pot body 1 through the feed port 12. The exhaust hole 15 can play the role of exhaust, thereby achieving the same pressure inside and outside the crucible pot body 1.

[0027] The limiting frame 4 is in the shape of a "rectangular frame" structure. The limiting frame 4 can limit the limiting block 8 so that the crucible cover 2 will not automatically separate from the crucible pot body 1.

[0028] The outer wall of the blocking plate 14 is an inclined surface, and the outer wall of the blocking plate 14 is slidingly connected to the inner wall of the feed trough 10. The bottom of the blocking plate 14 is fixedly connected with a telescopic rod 16, which can be extended and retracted, so that the blocking plate 14 can only move vertically downward without being skewed.

[0029] The telescopic rod 16 is movably connected to the second spring 13, and the bottom of the telescopic rod 16 is fixedly connected to the inner bottom wall of the feed trough 10. The blocking plate 14 can be reset by the elastic force of the second spring 13 after being free from the force.

[0030] During use, when the crucible pot body 1 is sintering the raw materials inside it and it is necessary to continue adding raw materials to the crucible pot body 1, the raw materials are directly placed into the feed port 12. The blocking plate 14 will move downward under the gravity of the raw materials, and then there is a large gap between the blocking plate 14 and the inner wall of the feed trough 10. The raw materials can enter the interior of the crucible pot body 1 through the gap and the feed channel 11. After the raw materials are separated from the blocking plate 14, the elastic force of the second spring 13 will drive the blocking plate 14 to move upward to the position of the raw materials, and then the blocking plate 14 can immediately block the feed port 12, thereby shortening the time to open the crucible cover 2 when adding materials in the middle of the device, and shortening the time that the raw materials inside the crucible pot body 1 are in contact with the air.

[0031] Example 2

[0032] Reference Figure 1-4 , which is the second embodiment of the present utility model, the outer wall of the crucible pot body 1 is provided with a groove 5, the inner side wall of the groove 5 is fixedly connected to the first spring 6, one end of the first spring 6 is fixedly connected to the moving block 7, the top of the moving block 7 is fixedly connected to the limiting block 8, the inner wall of the limiting frame 4 is slidably connected to the outer wall of the limiting block 8, and the limiting block 8 will move toward the inside of the groove 5 when subjected to a force, and will be reset by the elastic force of the first spring 6 when no force is applied.

[0033] The shape of the limit block 8 is a "right-angled trapezoid" structure. The outer wall of the limit block 8 is slidingly connected to the inner wall of the groove 5, and the outer wall of the moving block 7 is slidingly connected to the inner wall of the groove 5. A moving plate 9 is fixedly connected to one side of the moving block 7. The moving plate 9 can drive the moving block 7 and the limit block 8 to move toward the inside of the groove 5 under the action of force.

[0034] During use, the movable plate 9 is clamped by an external auxiliary clamp tool, so that the movable block 7 and the limit block 8 can be moved into the interior of the groove 5, thereby separating the limit block 8 from the limit frame 4, and the crucible cover 2 is no longer restricted, so that the crucible cover 2 can be disassembled and the raw materials inside the crucible pot body 1 can be discharged.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
