Description

Technical Field

[0001] The utility model belongs to the technical field of heating equipment in a high-temperature vacuum sintering furnace, and in particular relates to a vacuum material tank for a high-temperature vacuum sintering furnace. Background Art

[0002] When sintering materials in a high-temperature vacuum sintering furnace, a material tray or a material tank is needed as a material container, and then the material tray or material tank is placed in the sintering furnace for sintering. The temperature in the sintering furnace reaches 1000°C-1800°C. In a high-temperature atmosphere, the material tank not only needs to ensure its own sealing, but also ensure that the vacuum degree inside the material tank meets the process requirements. This requires vacuuming the inside of the material tank. Usually, a vacuum pipe connected to the inside of the material tank is set on the upper cover of the material tank, and vacuuming is performed through the vacuum pipe.

[0003] A vacuum material tank for a high-temperature vacuum sintering furnace with authorization announcement number CN 208398617 U includes a tank body, an upper cover, an inwardly rotating vacuum sealing component arranged on the upper cover, and an eccentric connecting piece for connecting the upper cover and the tank body. The inwardly rotating vacuum sealing component includes a fixed part and a movable part. The bottom of the fixed part is used to connect with the material tank, and the top of the fixed part is used to connect with the movable part. A cavity for accommodating the movable part is arranged inside the fixed part, and an air intake channel connected to the outside is arranged at the bottom of the cavity. The eccentric connecting piece includes a fixing pin, a left cam, a right cam, a connecting shaft, and a rotating rod. The utility model realizes the closing and conducting of the vacuum channel by combining and separating the movable part and the fixed part, and adopts surface-to-surface contact to seal the vacuum channel. It is not only sensitive and convenient to operate, but also has a good sealing effect, and there is no leakage, which is more suitable for repeated use.

[0004] Although the above application is sensitive and convenient to operate, and has a good sealing effect without leakage, and is more suitable for repeated use, the inner rotating vacuum sealing component is designed as an integral part with the upper cover and cannot be easily disassembled, resulting in subsequent damage and the upper cover can only be replaced together. At the same time, multiple bolts are required to fix the upper cover and the tank body, resulting in slow locking efficiency and greatly reducing the use efficiency. Therefore, a vacuum tank for a high-temperature vacuum sintering furnace is needed. Utility Model Content

[0011] As a preferred embodiment, the L-shaped rods are connected to the outer wall of the annular plate through springs, and C-shaped buckle rods are fixed to the outer wall of the L-shaped rods facing away from the springs. Multiple C-shaped buckle rods can facilitate fixing the upper cover to the top of the tank body.

[0012] As a preferred implementation, a shift block is fixedly connected to the outer side of the rotating disk.

[0013] Compared with the prior art, the vacuum tank for high temperature vacuum sintering furnace provided by the utility model has at least the following beneficial effects:

[0014] (1) By setting up a synchronous positioning structure, when the upper cover needs to be disassembled, the turntable can be rotated by the dial block, and the multiple inclined grooves can be used to make the multiple transmission columns move away from the mounting seat, so that each spring is stretched, and the L-shaped plug rods are disengaged from the sockets.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0021] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention. Example

[0022] Although the above application is sensitive and convenient to operate, and has a good sealing effect without leakage, and is more suitable for repeated use, the inner rotating vacuum sealing component is designed as an integral part with the upper cover 2, and cannot be easily disassembled, resulting in subsequent damage. The upper cover 2 can only be replaced together. At the same time, multiple bolts are required to fix the upper cover 2 and the tank body 1, resulting in slow locking efficiency, which greatly reduces the use efficiency.

[0023] To do this, see Figure 1-3The utility model provides a vacuum material tank for a high-temperature vacuum sintering furnace, comprising: a tank body 1, an upper cover 2 is movably overlapped at the entrance of the top of the tank body 1, a mounting seat 22 is movably mounted in a groove at the center of the top of the upper cover 2, an annular plate 21 is movably sleeved on the outer side of the mounting seat 22, the bottom end of the annular plate 21 is fixedly connected to the top of the upper cover 2, and a vacuum valve 3 is fixed on the mounting seat 22;

[0024] It also includes a synchronous positioning structure 4 which is installed on the annular plate 21 . The synchronous positioning structure 4 can quickly fix the mounting seat 22 and simultaneously fix and lock the upper cover 2 on the top of the tank body 1 .

[0025] Among them, the vacuum valve component 3 is the internal rotating vacuum sealing component in the authorization announcement number CN 208398617 U, which is the prior art and will not be described in detail.

[0026] Further Figure 1-3 As shown, it is worth explaining in detail that the vertical section of the mounting seat 22 is an inverted "convex" structure, and a sealing gasket is provided at the bottom end of the mounting seat 22. The setting of the sealing gasket can play a good sealing role when the mounting seat 22 is inserted into the groove.

[0027] Further Figure 1-3 As shown, it is worth specifically explaining that in order to enable the fixing of the upper cover 2 and the fixing of the mounting seat 22 to be performed using the same structure, a synchronous positioning structure 4 is provided, which includes a turntable 45 rotatably connected to the outside of the annular plate 21, and a plurality of inclined grooves 46 arranged in a ring array are provided on the turntable 45, and a transmission column 44 is movably overlapped in each inclined groove 46, and an L-shaped plug rod 42 is fixed to the top of the transmission column 44, and the L-shaped plug rod 42 is movably inserted on the annular plate 21, and one end of the L-shaped plug rod 42 is movably extended to The inner side of the annular plate 21 is inserted into the socket 421 provided on the outer wall of the mounting seat 22. The L-shaped plug rods 42 are slidably mounted on the outer side of the inverted L-shaped guide rod 41. The inverted L-shaped guide rods 41 are fixedly connected to the top of the annular plate 21. The L-shaped plug rods 42 are connected to the outer wall of the annular plate 21 through springs 43. A C-shaped buckle rod 47 is fixedly connected to the outer wall of the L-shaped plug rod 42 away from the spring 43. Multiple C-shaped buckle rods 47 can facilitate fixing the upper cover 2 to the top of the tank body 1. A shift block 48 is fixedly connected to the outer side of the turntable 45.

[0028] The width of the inclined slot 46 is equal to the diameter of the transmission column 44 .

[0029] In summary: when using the vacuum material tank for the high-temperature vacuum sintering furnace, if it is necessary to disassemble the vacuum valve component 3 on the upper cover 2 and the mounting seat 22 simultaneously, the turntable 45 can be rotated by the shift block 48, and then the multiple inclined grooves 46 can be cooperated to make the multiple transmission columns 44 move in a direction away from the mounting seat 22, thereby causing each spring 43 to be stretched, and the L-shaped plug rods 42 are disengaged from the sockets 421, and at the same time, each C-shaped buckle rod 47 is moved synchronously, and the lock fixation of the upper cover 2 is cancelled. In addition, if it is necessary to replace the vacuum valve component 3 installed on the mounting seat 22, it can be directly removed and replaced. In summary, the installation and fixation of the vacuum valve component 3 and the fixation of the upper cover 2 are completed by adopting the same structural setting, which greatly improves the use efficiency.
