Description

Technical Field

[0001] This application relates to a feed channel for a heating furnace. Background Technology

[0002] A heating furnace is an industrial device used to heat materials or workpieces (usually metal materials) to the temperature required for rolling, forging or heat treatment; the columnar materials or workpieces to be heated are fed and heated continuously in the transverse direction through the furnace channel.

[0003] In order to effectively guide the feeding direction, several horizontally arranged and parallel material guide troughs are set at the bottom of the current furnace channel. As long as the columnar material or workpiece to be heated is fed along the material guide trough, it will not deviate.

[0004] The existing furnace tunnels are all modular, consisting of an upper and lower section. Each material guide chute is located in the lower section, serving as a support and guide. The upper section is used to close the opening in the lower section, forming a tunnel with only openings at both ends. However, the disadvantages of this structure are that each assembly requires manual operation on-site, resulting in low processing efficiency and being time-consuming and labor-intensive. Moreover, assembly inevitably produces errors in shape, orientation, and position, leading to low processing accuracy, which in turn affects the installation of other supporting components. Further improvements are needed. Utility Model Content

[0005] In view of the current state of the prior art, the technical problem to be solved by this utility model is to provide a feeding channel for a heating furnace that adopts an integrated structure to effectively improve processing efficiency and achieve time and labor saving, while eliminating errors in shape, orientation and position to improve processing accuracy and ensure the smooth installation of other supporting components.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a feeding channel of a heating furnace, characterized in that it includes a seamless tube body, and an inverted V-shaped ridge parallel to the central axis of the seamless tube body is formed on the lower outer wall of the seamless tube body facing the interior of the seamless tube body. Two first straight sections are also formed on the lower outer wall of the seamless tube body, which are symmetrically arranged on the left and right sides of the opening of the V-shaped ridge and are parallel to each other. The ridge and the two first straight sections form two V-shaped guide grooves that are symmetrically arranged on the left and right sides and are parallel to each other in the lower interior of the seamless tube body. The seamless tube body also has a second straight section formed on the outer walls of both the front and rear sides. The two second straight sections are respectively located above the two V-shaped guide grooves and are distributed in parallel to each other. The inner walls of the two second straight sections form an inverted V-shaped smoke-collecting groove parallel to the central axis of the seamless tube body inside the upper part of the seamless tube body. A vertically arranged exhaust pipe is also inserted into the upper front end of the seamless tube, and the opening at the root of the exhaust pipe is connected to the interior of the inverted V-shaped smoke trough.

[0007] Preferably, the front edge of the root opening of the exhaust pipe is formed with a vertically arranged arc-shaped baffle that is concentrically distributed with the exhaust pipe.

[0008] Preferably, an arc-shaped notch is provided at the left and right corners of the end of the arc-shaped baffle, and the two arc-shaped notches are respectively located above the two V-shaped guide grooves.

[0009] Preferably, the front end of the seamless tube is further provided with vertically distributed baffles, and the left and right outer walls of the baffles are respectively fixed to the left and right inner walls of the inverted V-shaped smoke trough.

[0010] Preferably, the lower edge of the baffle has two arc-shaped grooves that are symmetrically distributed and located above two V-shaped guide grooves.

[0011] Preferably, the inner wall of each of the arc-shaped grooves is set at the same height as the inner wall of an arc-shaped notch on the same side.

[0012] Preferably, the rear edge of the root opening of the exhaust pipe is provided with an arc-shaped opening groove that is flush with the inner wall of the inverted V-shaped smoke-containing groove.

[0013] Compared with the prior art, the advantages of this utility model are: The seamless tube body of this utility model adopts an integrated structure. With the help of a special mold, V-shaped guide grooves and inverted V-shaped smoke troughs with fixed shape and position can be formed on the seamless tube body. When in use, it can be cut according to the length required, so there is no need for manual assembly on site, which effectively improves the processing efficiency and achieves the effect of saving time and labor. Moreover, since the radial cross-sectional shape of the seamless tube body is the same at any position, the errors in shape, direction and position are eliminated, thereby improving the processing accuracy and ensuring the smooth installation of other supporting components.

[0021] like Figures 1-2 As shown, a feeding channel for a heating furnace includes a seamless tube 1. The lower outer wall of the seamless tube 1 has an inverted V-shaped ridge 11 that is parallel to the central axis of the seamless tube 1 and faces the interior of the seamless tube 1. The lower outer wall of the seamless tube 1 also has two first straight sections 12 that are symmetrically arranged on the left and right sides of the opening of the V-shaped ridge 11 and are parallel to each other. The ridge 11 and the two first straight sections 12 form two V-shaped guide grooves 13 that are symmetrically arranged on the left and right sides and are parallel to each other inside the lower part of the seamless tube 1. On the outer walls of both the front and rear sides of the seamless tube body 1, there is a second straight section 14 that is symmetrically arranged. The two second straight sections 14 are respectively located above the two V-shaped guide grooves 13 and are distributed in parallel to each other. The inner walls of the two second straight sections 14 form an inverted V-shaped smoke-containing groove 15 that is parallel to the central axis of the seamless tube body 1 inside the upper part of the seamless tube body 1. A vertically arranged exhaust pipe 2 is also inserted into the upper front end of the seamless tube body 1, and the opening at the root of the exhaust pipe 2 is connected to the interior of the inverted V-shaped smoke container 15.

[0022] At the root opening of the exhaust pipe 2, a vertically arranged arc-shaped baffle 21 is formed on the front edge facing downwards and is concentrically distributed with the exhaust pipe 2.

[0023] An arc-shaped notch 22 is provided at the left and right corners of the end of the arc-shaped baffle 21, and the two arc-shaped notches 22 are respectively located above the two V-shaped guide grooves 13.

[0024] The front end of the seamless tube 1 is also provided with vertically distributed baffles 3. The left and right outer walls of the baffles 3 are respectively fixed to the left and right inner walls of the inverted V-shaped smoke trough 15.

[0025] Two arc-shaped grooves 31 are provided on the lower edge of the baffle 3, which are symmetrically distributed on the left and right and located above the two V-shaped guide grooves 13 respectively.

[0026] The inner wall of each arc-shaped groove 31 is set at the same height as the inner wall of an arc-shaped notch 22 on the same side.

[0027] The bottom outer wall of the inverted V-shaped smoke trough 15 has a rounded corner surface 16, and correspondingly, the upper edge of the baffle 3 has a rounded corner edge 32 that cooperates with the rounded corner surface 16.

[0028] An arc-shaped opening groove 23, flush with the inner wall of the inverted V-shaped smoke trough 15, is provided at the rear edge of the root opening of the smoke exhaust pipe 2.

[0029] How to use: Two short pieces are fed laterally into the front end of the seamless tube 1 and into the two V-shaped guide grooves 13 respectively. Then, the two short pieces are fed laterally into the front end of the seamless tube 11 in the same way. This will push the first two short pieces to move backward along the two V-shaped guide grooves 13 respectively, and so on.

[0030] A heating gun is installed behind the seamless tube 1 and the nozzle of the heating gun is aimed at the interior of the rear end of the seamless tube 1. After the heating gun is ignited, the flame will blow into the seamless tube 1 to raise the temperature inside the seamless tube 1, thereby heating the short material located inside the seamless tube 1.

[0031] The exhaust gas generated during the heating process will rise and remain in the inverted V-shaped smoke container 15, and then be discharged outward through the exhaust pipe 2.

[0032] The two arc-shaped grooves 31 on the baffle 3 and the two arc-shaped notches 22 on the exhaust pipe 2 both limit the height above the two V-shaped guide grooves 13, thereby preventing two or more short materials stacked one above the other from passing under the baffle 3 and the exhaust pipe 2.

[0033] The seamless tube body 1 of this utility model adopts an integrated structure. With the help of a special mold, V-shaped guide grooves 13 and inverted V-shaped smoke troughs 15 with fixed shape and position can be formed on the seamless tube body 1. When in use, it can be cut according to the length requirement, so there is no need for manual assembly on site, which effectively improves the processing efficiency and achieves the effect of saving time and labor. Moreover, since the radial cross-sectional shape of the seamless tube body 1 is the same at any position, the errors in shape, direction and position are eliminated, thereby improving the processing accuracy and ensuring the smooth installation of other supporting components.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
