In this device, the energy of the laser is used to heat an object to an extremely high temperature for the development and research work of new materials;

[0003] Since the working environment inside the cavity of this laser-heated gas suspension furnace is isolated from the working environment outside the cavity, there are also certain requirements for the transportation of materials. It is necessary to transport materials without affecting the internal working environment. For this purpose, we provide a feed rod for a containerless laser-heated suspension furnace to achieve this goal. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a feed rod for a containerless laser-heated suspension furnace to solve the problems raised in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A feed rod for a containerless laser-heated suspension furnace includes a feed rod thread seat for overall installation and fixation. A pressing groove is opened inside the feed rod thread seat, and a first sealing ring is installed at the bottom end inside the pressing groove. Above the pressing groove is a pressing block, and a second sealing ring is installed at the bottom of the pressing block corresponding to the first sealing ring;

[0007] A knurled nut is installed above the feed rod thread seat, and a feeding card sleeve pipe penetrates through the knurled nut, the pressing block and the inside of the feed rod thread seat;

[0008] The upper part of the knurled nut is fixedly connected to a first ball valve, and one end of the first ball valve away from the knurled nut is connected to a connecting card sleeve pipe, and the other end of the connecting card sleeve pipe is fixedly connected to a second ball valve.

[0009] As a further technical solution of the utility model, the outer diameter of the pressing block is the same as the inner diameter of the pressing groove, and the pressing block and the knurled nut are integrally formed.

[0010] As a further technical solution of the utility model, the second ball valve is communicated with the internal space of the first ball valve through the connecting card sleeve pipe, and the first ball valve is communicated with the internal space of the feeding card sleeve pipe.

[0011] As a further technical solution of the present utility model, the feed rod thread seat is of a flange structure, and a plurality of groups of bolts are connected through the periphery of the feed rod thread seat.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, through the two sets of ball valves provided, during use, the opening and closing process can be carried out according to the conveying sequence of the material, so that the material will not affect the internal working environment of the containerless laser heating levitation furnace during the conveying process, realizing the conveying process in a sealed environment;

[0014] In the present utility model, by setting the knurled nut to disengage from the feed rod thread seat, at this time, the pressing block is disengaged from the pressing card slot, resulting in the pressing block being unable to limit the feeding card sleeve in the pressing card slot. Since the feed rod thread seat is bolted to the device main body, the insertion depth of the feeding card sleeve into the device can be changed at this time, so as to convey the material to each position for processing.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-6 , in the embodiment of the present invention, a feed rod of a containerless laser heating suspension furnace includes a feed rod thread seat 1 for overall installation and fixation. A pressing groove 2 is provided inside the feed rod thread seat 1, and a first sealing ring 3 is installed at the bottom end inside the pressing groove 2. A pressing block 4 is arranged above the pressing groove 2, and a second sealing ring 5 is installed at the bottom of the pressing block 4 corresponding to the first sealing ring 3.

[0024] A knurled nut 6 is installed above the feed rod thread seat 1, and a feed card sleeve 7 penetrates through the inside of the knurled nut 6, the pressing block 4 and the feed rod thread seat 1.

[0025] A first ball valve 8 is fixedly connected above the knurled nut 6, and a connecting card sleeve 9 is connected to one end of the first ball valve 8 away from the knurled nut 6. The other end of the connecting card sleeve 9 is fixedly connected to a second ball valve 10.

[0026] In this embodiment, the outer diameter of the pressing block 4 is the same as the inner diameter of the pressing groove 2, and the pressing block 4 and the knurled nut 6 are integrally formed.

[0027] In this embodiment, the second ball valve 10 is communicated with the inner space of the first ball valve 8 through the connecting card sleeve 9, and the first ball valve 8 is communicated with the inner space of the feed card sleeve 7.

[0028] In this embodiment, the feed rod thread seat 1 is of a flange structure, and multiple groups of bolts penetrate through the periphery of the feed rod thread seat 1.

[0029] The working principle of the present invention is as follows: When in use, the feed rod thread seat 1 is fixedly connected to the containerless laser heating suspension furnace through bolts. When the containerless laser heating suspension furnace is working, first use a vacuum pump to evacuate, so that the cavity obtains a high vacuum, and then inject a high-purity protective atmosphere.

[0030] The inside of the containerless laser heating suspension furnace is always in a state of high-purity protective atmosphere. Therefore, when heating the material, it is necessary to prevent the mixing of impure gases outside the cavity and perform raw material transportation under a sealed condition.

[0031] First, place material particles or powder at the opening of the second ball valve 10. At this time, the first ball valve 8 and the second ball valve 10 are in the closed state, and the internal space of the feeding card sleeve pipe 7 located inside the containerless laser heating suspension furnace is in a sealed state;

[0032] Next, open the second ball valve 10. The material particles or powder fall into the connecting card sleeve pipe 9 between the second ball valve 10 and the first ball valve 8. After completing this step, close the second ball valve 10;

[0033] Then open the first ball valve 8. At this time, due to the closing of the second ball valve 10, the inside of the feeding rod is still in a sealed state. At this time, under the action of gravity, the material particles or powder fall along the feeding card sleeve pipe 7 into the designated position;

[0034] During this process, the knurled nut 6 can be disengaged from the feeding rod thread seat 1. At this time, the pressing block 4 is disengaged from the pressing card slot 2, resulting in the pressing block 4 being unable to limit the feeding card sleeve pipe 7 inside the pressing card slot 2. Since the feeding rod thread seat 1 is bolted to the device main body, the insertion depth of the feeding card sleeve pipe 7 into the device can be changed at this time, so as to convey the material to various positions for processing. (At the same time, a Figure 6 comparison is made)

[0035] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
