Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of artificial diamond processing, in particular to a furnace pouring port connection structure. Background Art
[0002] Diamond is commonly known as "diamond drill", which is what we often call diamond. It is a mineral composed of pure carbon and is also the hardest substance in nature. Since the 18th century, when it was confirmed that diamond is composed of pure carbon, people began to study artificial diamonds. It was only in the 1950s that through the progress of high-pressure research and high-pressure experimental technology, it achieved real success and rapid development. Artificial diamonds are also widely used in various industries and craft industries.
[0003] Artificial diamonds are generally formed by transforming graphite under high temperature and high pressure. In the prior art, alloy powder is often added to graphite to cultivate artificial diamonds. It is used in the industrial artificial diamond synthesis process to provide catalysis, reduce the reaction temperature and reduce the pressure required for the reaction. Generally, iron-nickel alloy powder is used.
[0004] In the process of processing iron-nickel alloy powder, it is necessary to mix the iron rods and nickel plates after impurities removal in proportion and then melt and atomize to make powder. During the melting process, the molten metal liquid in the furnace needs to be poured into the high-pressure atomizing furnace. In the prior art, an oil cylinder is used to directly drive the furnace to pour. Since the pouring port is separated from the furnace outlet by a certain distance, splashing will occur during pouring, and personnel need to stay away during operation, and the safety needs to be improved. At the same time, splashing causes metal cooling blocks to appear on the top of the high-pressure atomizing furnace and around the operating area, which are difficult to clean. Utility Model Content
[0005] The utility model aims to provide a furnace dumping port connection structure, which has a simple structure and can be automatically driven when the furnace rotates synchronously, so as to avoid splashing of molten metal liquid inside the furnace during dumping, thereby improving safety during operation.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a furnace pouring port connection structure, including a furnace and a high-pressure atomizing furnace, a flow outlet is provided on the top of the furnace, a fixed frame is provided on the outside of the furnace, a bracket is hingedly connected to the side of the fixed frame, a cylinder is fixed inside the bracket, the cylinder drives the fixed frame to rotate, a pouring port is fixed on the top of the high-pressure atomizing furnace, and the furnace is driven to rotate by the cylinder to pour the molten metal inside into the high-pressure atomizing furnace along the pouring port, a sliding sleeve is provided on the outside of the pouring port, an elastic metal ring is fixed on the top of the sliding sleeve, and a connecting curved rod is hingedly connected between the sliding sleeve and the fixed frame.
[0007] Furthermore, the elastic metal ring is composed of a plurality of independent metal sheets, and a metal connecting plate is fixed between the plurality of metal sheets.
[0008] Furthermore, the elastic metal ring is provided with a groove near the fixed frame, and the shape of the groove is consistent with the shape of the outflow port of the furnace.
[0009] Furthermore, the sliding sleeve is fixed with a first rotating seat on the side facing the melting furnace, the fixed frame is fixed with a second rotating seat on the side facing the high-pressure atomization furnace, and both ends of the connecting curved rod are respectively hinged inside the first rotating seat and the second rotating seat.
[0010] Furthermore, the bottom of the connecting bent rod is hingedly connected to the top of the high-pressure atomization furnace.
[0011] Furthermore, fixed tubes fixed to the top of the high-pressure atomizing furnace are provided on both sides of the pouring port, guide rods are slidably connected inside the fixed tubes, support plates are fixed to the ends of the guide rods away from the fixed tubes, and the sides of the support plates are fixed to the sides of the sliding sleeves.
[0012] The beneficial effect of the utility model is that the furnace pouring port connecting structure is connected between the fixed frame on which the furnace is placed and the pouring port through a connecting curved rod. When the furnace is poured, it is driven by the oil cylinder, and the fixed frame carries the furnace to rotate synchronously. The hinge between the curved rod and the fixed frame starts to rotate, and at the same time, the connecting curved rod is driven to rotate downward near the fixed frame end. The base point of the downward rotation is the connection between the connecting curved rod and the high-pressure atomizing furnace, so that the connecting curved rod starts to rotate upward near the sliding sleeve end, and then drives the sliding sleeve to move upward. At this time, the outflow port contacts the groove. As the oil cylinder is continuously pushed out, the outflow port presses the groove, so that the metal sheet at the opposite side of the groove is lifted upward, and then gradually covers the peripheral space above the pouring port, which can avoid splashing of molten metal liquid inside the furnace during pouring, thereby improving safety during operation.

DETAILED DESCRIPTION
[0016] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0017] Please also refer to Figure 1 to Figure 2 The following will describe in detail the furnace pouring port connection structure of the utility model embodiment in conjunction with the accompanying drawings.
[0018] like Figure 1 As shown, the furnace pouring port connection structure includes a furnace 1 and a high-pressure atomizing furnace 2. The furnace 1 is provided with a flow outlet 3 on the top, and a fixed frame 4 is provided outside the furnace 1. A bracket 5 is hingedly connected to the side of the fixed frame 4. A cylinder 6 is fixed inside the bracket 5. The cylinder 6 drives the fixed frame 4 to rotate. A pouring port 7 is fixed on the top of the high-pressure atomizing furnace 2. After the furnace 1 is driven to rotate by the cylinder 6, the molten metal inside is poured into the high-pressure atomizing furnace 2 along the pouring port 7. A sliding sleeve 8 is provided on the outside of the pouring port 7. An elastic metal ring 9 is fixed on the top of the sliding sleeve 8. A connecting curved rod 15 is hingedly connected between the sliding sleeve 8 and the fixed frame 4.
[0019] The elastic metal ring 9 is composed of a plurality of independent metal sheets 10 , and metal connecting plates 11 are fixed between the plurality of metal sheets 10 .
[0020] A groove 12 is provided on the side of the elastic metal ring 9 close to the fixed frame 4 , and the shape of the groove 12 is consistent with the shape of the outflow port 3 of the melting furnace 1 .
[0021] The metal sheet 10 is made of chromium-nickel-molybdenum alloy steel with a temperature resistance of more than 1500° C. and has a thickness of 1 cm. The metal connecting plate 11 used to connect the metal sheet 10 is made of the same material as the metal sheet 10 and has a thickness of 0.1 cm.
[0022] After applying pressure to the groove 12, since the above-mentioned chromium-nickel-molybdenum alloy steel maintains good toughness, the groove 12 is squeezed, the connecting plate is bent after squeezing, and the spacing between the metal sheets 10 on the side of the groove 12 is reduced, and the pressure applied to the groove 12 causes the metal sheet 10 to move toward the lower side close to the groove 12. At the same time, the force required to bend the middle part of the metal sheet 10 is relatively large, so the overall shape of the metal sheet 10 remains unchanged, and the same metal sheet 10 on the opposite side of the groove 12 moves upward. After pressing the groove 12, the metal sheet 10 on the opposite side of the groove 12 is lifted upward, and bent similarly to a telescopic bend.
[0023] At the same time, a first rotating seat 13 is fixed to the sliding sleeve 8 facing the melting furnace 1, and a second rotating seat 14 is fixed to the fixed frame 4 facing the high-pressure atomization furnace 2. Both ends of the connecting curved rod 15 are hinged inside the first rotating seat 13 and the second rotating seat 14 respectively.
[0024] The bottom of the connecting bent rod 15 is hingedly connected to the top of the high-pressure atomizing furnace 2 .
[0025] At the same time, fixed pipes 16 fixed to the top of the high-pressure atomizing furnace 2 are provided on both sides of the pouring port 7, and a guide rod 17 is slidably connected inside the fixed pipe 16. A support plate 18 is fixed to the end of the guide rod 17 away from the fixed pipe 16, and the side of the support plate 18 is fixed to the side of the sliding sleeve 8.
[0026] When the sliding sleeve 8 moves vertically upward along the pouring opening 7 , the guide rod 17 is driven to move along the inside of the fixed tube 16 , and the upward driving of the sliding sleeve 8 is achieved by connecting the bent rod 15 .
[0027] The connecting bent rod 15 is connected at three points and can rotate at the three points.
[0028] Specifically, the working principle of the utility model is as follows: when the furnace 1 is tipped, it is driven by the oil cylinder 6, the oil cylinder 6 is pushed upward, and the fixed frame 4 carries the furnace 1 to rotate synchronously, and the furnace 1 gradually rotates until its outflow port 3 is placed above the pouring port 7. While the fixed frame 4 is rotating, since the overall length and shape of the bent rod remain unchanged, the hinge between the bent rod and the fixed frame 4 begins to rotate, and at the same time drives the connecting bent rod 15 to rotate downward near the end of the fixed frame 4. The base point of the downward rotation is the connection between the connecting bent rod 15 and the high-pressure atomizing furnace 2, so that the connecting bent rod 15 begins to rotate upward near the end of the sliding sleeve 8, and then drives the sliding sleeve 8 to move upward. At this time, the outflow port 3 contacts the groove 12. As the oil cylinder 6 is continuously pushed out, the outflow port 3 applies pressure to the groove 12, thereby lifting the metal sheet 10 at the opposite side of the groove 12 upward, and then gradually covering the peripheral space above the pouring port 7, which can prevent the molten metal liquid inside the furnace 1 from splashing out during tipping.
[0029] The fixing structure between the fixed frame 4 and the furnace 1 is a conventional technology in the art. When the fixed frame 4 is pushed out by the oil cylinder 6, the furnace 1 can rotate synchronously therewith.
[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
