Description

Technical Field

[0001] The utility model relates to the field of quartz glass tube production, in particular to a continuous melting furnace for preparing small-aperture quartz glass tubes. Background Art

[0002] A continuous melting furnace is a smelting device that operates in a continuous mode. It melts raw materials such as iron ore, scrap steel, and high-purity quartz sand through electrolysis, combustion, or other heating methods to produce continuous strips or other shaped materials. Continuous melting furnaces are required for the production of quartz glass tubes. However, existing continuous melting furnaces have the following disadvantages when producing small-diameter quartz glass tubes:

[0003] (1) When using a continuous melting furnace to produce quartz glass tubes, a lifting device is generally used to lift the quartz stone packaging bag, and then workers approach the continuous melting furnace and cut the packaging bag, so that the raw materials fall into the continuous melting furnace. This loading method has a great safety hazard.

[0004] (2) When the raw materials are poured into the continuous melting furnace, a certain amount of dust will be present in the raw materials. The dust will not only affect the purity of the smelted product, but may also be inhaled by the workers, thereby affecting their health.

[0005] Therefore, we made improvements to this problem and proposed a continuous melting furnace for preparing small-aperture quartz glass tubes. Utility Model Content

[0029] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings.

Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0033] like Figure 1-5 As shown, this embodiment provides a continuous melting furnace for preparing small-aperture quartz glass tubes, comprising a continuous melting furnace body 1. A loading mechanism 2 is provided on the outside of the continuous melting furnace body 1 for facilitating the loading of quartz stone. A blowing assembly 3 is provided on one side of the loading mechanism 2 for blowing away dust in the quartz stone raw material.

[0034] The feeding mechanism 2 includes a circular tube 201, a rotating rod 202, a spiral blade 203, a servo motor 204, a feeding port 205, a discharge pipe 206 and a support rod 207. The circular tube 201 is arranged on one side of the continuous melting furnace body 1. The rotating rod 202 is rotatably connected to the inside of the circular tube 201 and is located at the central axis of the circular tube 201. The spiral blade 203 is fixedly connected to the outer wall of the rotating rod 202 and the side wall is tightly fitted with the inner wall of the circular tube 201. The servo motor 204 is arranged at one end of the circular tube 201 away from the continuous melting furnace body 1. The feeding port 205 is connected to the outer wall of the circular tube 201 and is located above the circular tube 201. The discharge pipe 206 is connected to the circular tube 201. The outer wall of the circular tube 201 is arranged below the circular tube 201, the support rod 207 is bolted to the outer wall of the circular tube 201, the circular tube 201 is arranged tilted, the servo motor 204 is coaxially arranged with the rotating rod 202 and can drive the rotating rod 202 to rotate, the feed port 205 and the discharge pipe 206 are respectively located at both ends of the circular tube 201. When in use, the raw materials are poured into the inside of the feed port 205, and then the servo motor 204 is connected to the external power supply and the servo motor 204 is started. The servo motor 204 drives the rotating rod 202 and the spiral blade 203 to rotate, thereby transporting the raw materials. When the raw materials are transported to the discharge pipe 206, the raw materials will fall into the interior of the continuous melting furnace body 1, thereby completing the loading.

[0035] like Figure 3 and Figure 4As shown, the blowing assembly 3 includes a base plate 301, a mounting plate 302, a vertical rod 303, a circular frame 304 and a fan 305. The base plate 301 is arranged below the continuous melting furnace body 1, the mounting plate 302 is bolted to the top of the base plate 301, the vertical rod 303 is bolted to the top of the mounting plate 302, the circular frame 304 is rotatably connected to the top of the vertical rod 303, and the fan 305 is bolted to the inside of the circular frame 304. The fan 305 is started in advance. When the raw material falls from the discharge pipe 206, the wind blown by the fan 305 will blow away the dust in the raw material, thereby improving the purity of the raw material, and thus also improving the quality of the output product.

[0036] like Figure 4 As shown, a positioning frame 4 is welded on the side wall of the continuous melting furnace body 1, and the internal thread of the positioning frame 4 is connected with a bolt 5. There are four positioning frames 4 and four bolts 5, which are distributed circumferentially along the central axis of the furnace body 1. One end of the bolt 5 extends to the inside of the bottom plate 301 and is threadedly connected to the bottom plate 301. When in use, the bolt 5 is screwed into the inside of the positioning frame 4 and the bottom plate 301 in turn, thereby fixing the continuous melting furnace body 1 and improving the stability during product manufacturing.

[0037] like Figure 1 As shown, the bottom of the support rod 207 is bolted with a fixed plate 6, and the bottom of the fixed plate 6 is bolted with a universal wheel 7 for facilitating the movement of the circular tube 201. There are four universal wheels 7, which are respectively located at the four corners of the bottom of the fixed plate 6. When in use, the universal wheels 7 can be used to facilitate the movement of the loading mechanism 2 to the specified position, thereby increasing convenience.

[0038] like Figure 1 As shown, a buffer pad 8 is bonded to the side wall of the fixed plate 6 to prevent collision between the fixed plate 6 and the bottom plate 301. The buffer pad 8 is made of rubber. There are four buffer pads 8, which are respectively located at the four corners of the fixed plate 6. When the fixed plate 6 is pushed to move during use, the fixed plate 6 may collide with the bottom plate 301, thereby causing a dent. At this time, the buffer pad 8 can provide protection for the fixed plate 6 and the bottom plate 301.

[0039] like Figure 4 As shown, a connecting rod 9 is bolted to the side wall of the support rod 207, and a reinforcing rod 10 is bolted to the bottom of the connecting rod 9. One end of the reinforcing rod 10 is bolted to the side wall of the support rod 207. When in use, the connecting rod 9 and the reinforcing rod 10 can improve the stability between the two adjacent support rods 207, thereby improving the stability of the circular tube 201 when conveying materials.

[0040] like Figure 1 As shown, a flaring frame 11 for increasing the feed amount is welded on the top of the feed port 205. When in use, the flaring frame 11 can increase the amount of raw materials entering the interior of the circular tube 201, thereby improving the feeding efficiency.

[0041] Specifically, when the continuous melting furnace for preparing small-aperture quartz glass tubes is in use: the fixing plate 6 is pushed to one side of the continuous melting furnace body 1. At this time, the fixing plate 6 may collide with the bottom plate 301, thereby causing a depression. At this time, the buffer pad 8 can provide protection for the fixing plate 6 and the bottom plate 301. Then the servo motor 204 and the fan 305 are connected to the external power supply, and the servo motor 204 and the fan 305 are started. Then the raw materials are poured into the expansion frame 11 and the inside of the feed port 205. At this time, the servo motor 204 drives the rotating rod 202 and the spiral blade 203 to rotate, thereby transporting the raw materials. When the raw materials are transported to the discharge pipe 206 and fall, the wind blown by the fan 305 will blow away the dust in the raw materials, thereby improving the purity of the raw materials. Then the raw materials will fall into the inside of the continuous melting furnace body 1, thereby completing the loading. After the loading is completed, the continuous melting furnace body 1 can be used to produce small-aperture quartz glass tubes.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
