Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-9 As shown: One embodiment of the present invention is:

[0031] A reaction kettle for carbon-coated silver wire processing, comprising a kettle body 1, the outer wall of the kettle body 1 is wrapped with an internally hollow heating sleeve 2, and the heating sleeve 2 is respectively connected to a water inlet pipe and a water outlet pipe, so that external hot water is injected into the heating sleeve 2 to heat the kettle body 1 in a water bath, the heating sleeve 2 is symmetrically fixed with fixed blocks 3 on the opposite side walls, an internally threaded sleeve 4 is fixed at the bottom of the fixed block 3, and a screw 5 is threadedly connected to the inner cavity of the internally threaded sleeve 4, the top cover of the kettle body 1 is provided with a kettle cover 6, and the two sides of the kettle cover 6 are respectively rotatably connected to the two screws 5 through connecting blocks, a rotating drive member 7 is installed on the top of the kettle cover 6, and the rotating drive member 7 is respectively connected to the two screws 5, the outer wall of one end of the kettle body 1 close to the kettle cover 6 extends outward to form an internally hollow limit ring 8, and the limit ring 8 rotates at equal angles between the top and the bottom of the inner cavity It is connected with a plurality of first nuts 9, a rotating gear 10 is fixedly connected to the outer wall of the first nuts 9, a rotating ring 11 is rotatably connected to the outer wall of the limiting ring 8 (the top and bottom of the rotating ring are rotatably connected to the limiting ring by means of grooves and bars that cooperate with each other), a plurality of first gear teeth 12 and second gear teeth 13 are respectively arranged at equal angles on the inner wall and outer wall of the rotating ring 11, and a plurality of first gear teeth 12 are meshed with the rotating gear 10, a gear column 14 that always meshes with the second gear teeth 13 is fixedly connected to the outer wall of the screw rod 5, and the outer wall of the kettle cover 6 extends outward to form an abutment ring 15 that cooperates with the limiting ring 8, and a plurality of first bolt columns 16 that are arranged one by one with the first nuts 9 are fixedly connected to the abutment ring 15 at equal angles, and the number of first nuts 9 can be 8 groups, 10 groups and 12 groups.

[0032] In this embodiment, a sealing groove 17 is extended outward from the top opening of the kettle body 1, and a sealing strip 18 that cooperates with the sealing groove 17 is provided at the bottom of the kettle cover 6. When the kettle cover is pressed down, the sealing strip can be inserted into the sealing groove, and as the kettle cover is pressed down, the sealing strip is deformed and tightly adheres to the inner wall of the sealing groove, thereby achieving sealing between the kettle cover and the kettle body.

[0033] In this embodiment, the rotating drive member 7 includes a mounting frame 71 fixedly connected to the kettle cover 6, and the mounting frame 71 is installed with a driving motor 72. The output end of the driving motor 72 passes through the mounting frame 71 and is installed with a driving sprocket 73. The outer walls of the two screw rods 5 are symmetrically fixed with driven sprockets 74, and the two driven sprockets 74 are connected to the driving sprocket 73 through a transmission chain 75. The rotation of the driving motor drives the driving sprocket to rotate, and then the two driven sprockets and the screw rod are synchronously driven to rotate through the transmission chain, so as to realize the smooth lifting and lowering of the kettle cover.

[0034] In this embodiment, two supporting feet 19 parallel to the internal threaded sleeve 4 are symmetrically fixed to the bottom of the heating sleeve 2, and the two supporting feet 19 are distributed at equal angles to the two internal threaded sleeves 4, so that the kettle body can be placed stably and there can be enough operating space outside the kettle body without interfering with the collection of materials.

[0035] In the present embodiment, in order to facilitate the collection of the generated carbon-coated silver wires and improve the subsequent processing efficiency, the bottom of the kettle cover 6 is detachably connected with a lining 20, and the lining 20 is located inside the kettle body 1 and abuts against the inner wall of the kettle body 1. After the carbon-coated silver wires are processed, the lining can be driven to rise by the rising of the kettle cover, so that the lining is separated from the kettle body, and then the lining is removed from the kettle cover and the carbon-coated silver wires are collected. During the collection process, a new lining can be installed to carry out the next processing flow.

[0036] In this embodiment, a plurality of second bolt columns 21 are installed at equal angles on the bottom of the kettle cover 6, and a through hole that cooperates with the second bolt column 21 is opened on the outer edge of the top opening of the liner 20. The second bolt column 21 passes through the through hole and is threadedly connected with a second nut 22. During installation, the second bolt is inserted into the through hole and then locked and fixed by the second nut to complete the installation.

[0037] In this embodiment, in order to improve the heat exchange efficiency between the liner and the kettle body, a first spiral bar 23 is provided on the outer wall of the liner 20, and a second spiral bar 24 cooperating with the first spiral bar 23 is provided on the inner wall of the kettle body 1. The second bolt column 21 is rotatably connected to the kettle cover 6. When the liner is installed, the first spiral bar and the second spiral bar can be staggered by rotation, thereby increasing the contact area between the kettle body and the liner, so that the heating effect of the liner is higher.

[0038] In this embodiment, in order to reduce the use of driving members, reduce costs and only need to open a group of through holes on the kettle cover for the driving members to pass through (thus reducing the possibility of leakage of the kettle cover), a T-shaped rotating groove 25 is opened at the bottom of the kettle cover 6, and a T-shaped rotating ring 26 is rotatably connected inside the T-shaped rotating groove 25. The second bolt column 21 is fixedly connected to the bottom of the T-shaped rotating ring 26. The power output end of the rotating driving member 7 passes through the kettle cover 6 and is installed with an outer gear ring 27. The outer gear ring 27 is installed and fixed by a connecting rod. The outer gear ring 27 is meshed and connected with an inner gear ring 28, and the outer wall of the inner gear ring 28 is fixedly connected to a plurality of second bolt columns 21. When the rotating driving member rotates, it can drive the inner gear ring to rotate, thereby driving the outer gear ring and the second bolt columns to rotate, and finally driving the inner liner to rotate synchronously. The rotation of the rotating driving member can also synchronously drive the kettle cover to descend, so that the inner liner can be lowered while rotating, and the staggered arrangement of the first spiral strips and the second spiral strips is realized.

[0039] In this embodiment, the outer wall of the kettle body 1 is provided with a spiral groove 29 overlapping with the second spiral strip 24, so that the hot water in the heating jacket can flow into the spiral groove, so that the hot water can be as close to the lining as possible, thereby efficiently heating the lining.

[0040] In this embodiment, a plurality of concentric annular heat-conducting strips 30 are arranged at the bottom of the inner cavity of the kettle body 1, and a heat-conducting groove 31 cooperating with the annular heat-conducting strips 30 is opened at the bottom of the lining 20. The cooperation between the annular heat-conducting strips and the heat-conducting grooves can not only limit the position of the lining, but also ensure that the bottom of the lining can also be heated, thereby ensuring the uniformity of heating.

[0041] In this embodiment, in order to make the carbon-coated silver wire evenly coated, a vibration motor is arranged outside the heating sleeve to make the inner lining vibrate, and the transmission of the vibration force can be ensured by the cooperation of the first spiral strip and the second spiral strip.

[0042] The specific working process of this embodiment is as follows:

[0043] In this embodiment, the carbon-coated silver wire is processed by hydrothermal method, which is as follows:

[0044] Silver wire and liquid containing carbon source are added into the inner liner 20 (the inner liner 20 is stainless steel), and then the drive motor 72 is started in the forward direction to drive the two screws 5 to rotate, so that the screws 5 drive the kettle cover 6 to rise to a certain height with the cooperation of the internal threaded sleeve 4, and then the drive motor 72 is turned off.

[0045] Then align the through hole of the liner 20 with each second bolt column 21 in turn, insert it, and then lock and fix it with the second nut 22 (when aligning, it is necessary to ensure the relative position between the first spiral strip 23 and the second spiral strip 24 to ensure the subsequent screwing in). After the liner 20 is fixed, start the drive motor 72 in the reverse direction. The drive motor 72 drives the screw rod 5 and the kettle cover 6 to descend, and when the screw rod 5 rotates, it can synchronously drive the gear column 14 to rotate. The gear column 14 drives the rotating ring 11 and the first gear teeth 12 to rotate through the second gear teeth 13, thereby driving the rotating The gear 10 and the first nut 9 rotate, and the first bolt column 16 is gradually inserted into the first nut 9 during the descent of the kettle cover 6, and is gradually locked and fixed as the first nut 9 rotates. The kettle cover 6 descends to insert the sealing strip 18 into the sealing groove 17. Only after the kettle cover 6 is completely covered on the kettle body 1, the drive motor 72 is turned off. During the descent of the kettle cover 6, the drive motor 72 synchronously drives the outer gear ring 27 to rotate, and drives the inner gear ring 28 and the second bolt column 21 to rotate, so that the liner 20 is screwed into the kettle body 1 while rotating and descending.

[0046] After the kettle body 1 is sealed, high-temperature liquid is added into the heating jacket 2 through the liquid inlet pipe. The liquid flows into the heating jacket 2 and into the spiral groove and the annular heat conductive strip 30, and heats the lining 20. After being heated to a certain temperature, the inside of the kettle body 1 is pressurized, and then the high temperature and high pressure state is maintained for a period of time for reaction. During the reaction, the external vibration motor can be turned on to make the lining 20 and the kettle body 1 vibrate synchronously, so that the silver wire and the solution are fully mixed.

[0047] After the reaction is completed, the drive motor 72 is started in the forward direction to drive the kettle cover 6 and the liner 20 to a specified height, and then the second nut 22 is loosened and the liner 20 is removed to collect the product.

[0048] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
