Description

Technical Field

[0001] The invention relates to the technical field of furnace charge preheating, in particular to a multi-point heating copper rod processing furnace charge preheating device. Background Art

[0002] Copper rods or copper bars as raw materials usually need to undergo secondary processing during use. Before the copper rods as blanks undergo secondary processing, they usually need to be heated to improve the plasticity of the copper rods, so as to facilitate secondary processing and forming steps such as stretching and extrusion in subsequent operations.

[0003] When copper rods are subjected to this type of treatment, flame heating is a common heating method. Specifically, the copper rod is first placed in a furnace, and then a flame is introduced into the furnace to heat the copper rod using the high temperature of the flame. During the heating process, the high-temperature exhaust gas inside the furnace needs to be discharged to the outside. To achieve this high-temperature exhaust gas utilization, people often use the waste heat of the exhaust gas to preheat the copper rod, thereby improving the subsequent heating efficiency of the copper rod.

[0004] Most current preheating methods use contact preheating, which involves directing high-temperature exhaust gas into a preheating furnace to generate high temperatures inside. A copper rod is then placed on a base within the furnace, which then drives the rod through the base to preheat the rod. However, due to the contact between the base and the rod, the contact area between the base and the rod is difficult to directly heat, which affects the preheating efficiency of the copper rod.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0023] See also Figure 1 As shown, a multi-point heating copper rod processing charge preheating device is provided, which includes a furnace body 100, a preheating channel 101 is provided inside the furnace body 100, and both ends of the preheating channel 101 are set through the furnace body 100, so that one end of the furnace body 100 forms an inlet and the other end forms an outlet. At the same time, the furnace body 100 and the preheating channel 101 are both inclined, and the inclination direction is referenced to Figure 3 As shown, the high part of the inclination is the exit, and the low part is the entrance. In this way, the copper rod carrier 120 located at the entrance can move toward the exit under the action of gravity. In order to reduce the loss of hot air, the present invention provides a first baffle 103 at both the exit and the entrance. The first baffle 103 is made of a flexible material. When the copper rod body 200 passes through the exit or the entrance, the first baffle 103 will deform to allow the copper rod body 200 to pass through. In addition, other methods can also be used to block the exit and the entrance. For example, a hydraulic rod is provided on the top of the first baffle 103, and the hydraulic rod is fixed to the top of the furnace body 100. When the copper rod body 200 passes through the exit or the entrance, the hydraulic rod drives the first baffle 103 to move upward, so that the exit and the entrance can also be opened.

[0024] The preheating channel 101 is connected to an exhaust pipe 102 that passes through the top of the furnace body 100 and is used to discharge the gas in the preheating channel 101.

[0025] like Figure 2As shown, there is a hollow structure between the interior of the furnace body 100 and the exterior of the preheating channel 101. The first partition 104 is provided at the bottom of the preheating channel 101, dividing the lower part of the furnace body 100 into an air distribution cavity 105 and the upper part into an air collection cavity 106. One end of the air distribution cavity 105 is connected to the air inlet 107 (combined with the Figure 1 As shown), it is used to transport the high-temperature exhaust gas into the air distribution chamber 105. In addition, the air distribution chamber 105 and the air collecting chamber 106 are in a communicating state. Specifically, a plurality of air vents 110 are provided on both sides of the top of the first partition plate 104, and the plurality of air vents 110 are arranged in parallel along the length direction of the furnace body 100. In this way, the high-temperature exhaust gas in the air distribution chamber 105 can enter the air collecting chamber 106 through the air vents 110. Next, a plurality of air guide pipes 111 connected to the air collecting chamber 106 are provided in the inner circle of the preheating channel 101 to guide the high-temperature exhaust gas in the air collecting chamber 106 into the preheating channel 101. At the same time, the air guide pipes 111 are inclined toward the copper rod body 200, so that the high-temperature exhaust gas discharged through the air guide pipes 111 can be blown directly to the copper rod body 200, thereby achieving preheating of the copper rod body 200.

[0026] To prevent heat from being lost to the outside through the furnace body 100 , the present invention performs heat insulation treatment on the furnace body 100 . Specifically, a heat insulation layer 108 is provided on the inner wall of the furnace body 100 . The heat insulation layer 108 is, for example, an aluminum silicate blanket, thermal insulation cotton, etc.

[0027] like Figure 3 As shown, a second partition 112 is provided inside the gas collecting cavity 106. The outer ring shape of the second partition 112 matches the inner wall shape of the furnace body 100, and the inner ring shape matches the outer ring shape of the preheating channel 101 (refer to Figure 4 ), for separating the space inside the gas collecting cavity 106. The number of the second partition 112 can be one or more. Figure 3 In the embodiment shown, two second partitions 112 are taken as an example. Specifically, the two second partitions 112 are fixedly arranged inside the gas collecting cavity 106, thereby dividing the inside of the gas collecting cavity 106 into three mutually incommunicable spaces. At the same time, a plurality of vents 110 are arranged corresponding to the three spaces, that is, there is a vent 110 in each space (refer to Figure 3 The high-temperature exhaust gas in the air distribution cavity 105 can enter different spaces through different air vents 110.

[0028] In addition, an adjustment zone 113 is formed inside the preheating channel 101, corresponding to the area between the two second partitions 112, and preheating zones 114 are formed at both ends. Meanwhile, the air duct 111 is disposed within the preheating zone 114. Next, a copper rod carrier 120 is disposed at the bottom of the preheating channel 101 for driving the copper rod body 200 to move within the preheating channel 101. The copper rod carrier 120 includes a plurality of rollers 122 supported at the bottom of the copper rod body 200. Furthermore, a drive unit communicating with the gas collecting chamber 106 is disposed within the adjustment zone 113; and a gas pressure regulating member 130 is disposed within the gas distribution chamber 105 for controlling pressure changes within the gas distribution chamber 105. When the copper rod carrier 120 moves, the air pressure regulating part 130 increases the pressure of the air distribution cavity 105 in front of the copper rod carrier 120. When the copper rod carrier 120 moves into the regulating area 113, the driving part drives the roller 122 to rotate under the action of the increased pressure, and then the roller 122 drives the copper rod body 200 to flip over in the regulating area 113, thereby achieving uniform preheating of the copper rod body 200.

[0029] Among them, such as Figure 7 As shown, the air pressure regulating member 130 includes a piston plate 131 fixedly connected to the copper rod carrier 120. The side wall of the piston plate 131 is provided with a closable opening 132. When the copper rod carrier 120 drives the piston plate 131 to move, the opening 132 is closed, thereby increasing the pressure in the air distribution chamber 105 in front of the piston plate 131.

[0030] That is to say, the copper rod body 200 is supported by using the roller 122. When the copper rod body 200 moves to the adjustment area 113, the high pressure in the air distribution cavity 105 drives the roller 122 to rotate through the driving part, thereby causing the copper rod body 200 located above the roller 122 to rotate together, realizing the change of the contact point between the copper rod body 200 and the copper rod carrier 120, thereby improving the efficiency of preheating the copper rod body 200.

[0031] like Figure 3-Figure 5As shown, a limit member 140 is provided within the adjustment area 113. The limit member 140 includes a connecting tube 141 having one end connected to one of the vents 110 and the other end extending to the side of the copper rod carrier 120 in the direction of movement. A piston block 142 is slidably connected to the interior of the connecting tube 141 at one end located in the direction of movement of the copper rod carrier 120. A second baffle 143 that can extend into the moving path of the copper rod carrier 120 is fixedly connected to the side wall of one end of the piston block 142. A return spring 144 is provided between one end of the piston block 142 and the end of the connecting tube 141 to elastically connect the two. Under normal conditions, the return spring 144 limits the second baffle 143 outside the moving path of the copper rod carrier 120. The second baffle 143 is a plate-shaped structure and has a roller rotatably provided toward one side of the bracket 121. The roller can reduce the friction between the bracket 121 and the second baffle 143 to facilitate the movement of the second baffle 143.

[0032] like Figure 7 and Figure 8 As shown, the copper rod carrier 120 includes a bracket 121 that is slidably arranged at the bottom of the preheating channel 101 along the length direction of the furnace body 100. The bracket 121 is a box-like structure with an opening at the top, and the two opposite side walls are recessed downward to accommodate the copper rod body 200. The two ends of the roller 122 are coaxially fixedly connected to a shaft, and the roller 122 is rotatably arranged on both sides of the bracket 121 through the shaft. A cam 123 is fixedly arranged on the shaft at one end of one of the rollers 122. On the other hand, the top height of the roller 122 is higher than the top height of the bracket 121 to prevent the copper rod body 200 from contacting the top of the bracket 121. And, as shown in FIG. Figure 8 As shown, the inner wall of the bracket 121 close to the roller 122 is in contact with the outer ring of the roller 122, which can prevent the discharge of gas and cooperate with the exhaust channel 124 to be described in detail below.

[0033] The exhaust passage 124 is provided through one side of the bracket 121, and the penetration portion is preferably above or below the center of the roller 122. Figure 8 In the embodiment shown, the penetration portion is located below the center of the roller 122, so that Figure 8 Taking the state of the rotating roller 122 as an example, when the gas enters the exhaust passage 124 , the gas will push the rotating roller 122 to rotate in a clockwise direction.

[0034] It should be added that a plurality of grooves are formed on the outer ring of the roller 122 so that the outer ring of the roller 122 forms a tooth shape, thereby facilitating the gas in the exhaust channel 124 to push the roller 122 to rotate.

[0035] There are many ways for the support 121 to slide on the bottom of the preheating channel 101, for example, Figure 2 and Figure 7In the illustrated embodiment, the bottom of the bracket 121 protrudes downward to form a slide rod, which is parallel to the length of the furnace body 100. The bottom of the preheating channel 101 is recessed downward to form a slide rail, which is parallel to the length of the furnace body 100. Thus, by placing the slide rod within the slide rail, a sliding connection between the bracket 121 and the bottom of the preheating channel 101 is achieved. In other embodiments, a rotating wheel, ball bearing, or other component can also be provided at the bottom of the bracket 121, as long as the bracket 121 can move at the bottom of the preheating channel 101.

[0036] exist Figure 6 and Figure 7 In the figure, the bottom of the preheating channel 101 and the bottom of the first partition 104 are both penetrated by a through groove 109, and the through groove 109 is parallel to the length direction of the furnace body 100; the middle of the top of the piston plate 131 protrudes upward to form a connecting block, which passes through the through groove 109 and is fixedly connected to the bottom of the bracket 121.

[0037] A movable plate 133 is longitudinally slidably connected to the sidewall of piston plate 131. Multiple openings 132 are longitudinally provided, extending through both piston plate 131 and movable plate 133. A follower arm 134 is fixed to the top of movable plate 133, its top end extending below cam 123. A connecting spring 135 elastically connects the top of movable plate 133 to the sidewall of piston plate 131. Under normal conditions, openings 132 in the sidewall of movable plate 133 are misaligned with openings 132 in the sidewall of piston plate 131.

[0038] In the above description, the return spring 144 and the connecting spring 135 are preferably made of high temperature resistant materials, such as ceramics.

[0039] It should be noted that the protruding end of the cam 123 is in a triangular shape, and the top end of the driven arm 134 is also in a triangular shape. This reduces the contact area between the top end of the driven arm 134 and the protruding end of the cam 123, and the protruding end of the cam 123 does not get stuck on the top of the driven arm 134, so that the connecting spring 135 can drive the movable plate 133 to move upward and reset.

[0040] like Figure 3 and Figure 4 As shown, the driving part is a ventilation pipe 150 fixedly arranged on the inner wall of the preheating channel 101. Figure 3In the illustrated embodiment, one end of the ventilation tube 150 communicates with the gas collecting chamber 106, while the other end abuts against the sidewall of the bracket 121. When the end of the bracket 121 abuts against the sidewall of the second baffle 143, the ventilation tube 150 communicates with the exhaust passage 124. Furthermore, in other embodiments, the ventilation tube 150 can be directly connected to the gas distribution chamber 105. Specifically, one end of the gas distribution chamber 105 passes through the preheating passage 101 and the first baffle 104, then extends into the gas distribution chamber 105 and communicates with the gas distribution chamber 105. In this way, high-temperature exhaust gas within the gas distribution chamber 105 can be discharged directly through the gas distribution chamber 105.

[0041] Working principle: Combine Figures 9-11 As shown, the high-temperature exhaust gas enters the air distribution chamber 105 through the air inlet 107, then enters the air collecting chamber 106 through the air vent 110, enters the preheating channel 101 through the air guide 111, and is finally discharged through the exhaust pipe 102. Due to the high pressure of the high-temperature exhaust gas, the high-pressure exhaust gas in the air distribution chamber 105 pushes the piston plate 131 toward one end of the preheating channel 101, causing the piston plate 131 to move the bracket 121 to the end (i.e., the inlet) of the preheating channel 101.

[0042] When the copper rod 200 is placed on top of the roller 122, its considerable weight acts on the bracket 121, causing the piston plate 131 at the bottom of the bracket 121 to overcome the pressure of the high-temperature exhaust gas within the gas distribution chamber 105 and move toward the other end (i.e., the outlet) of the preheating channel 101. As the bracket 121 drives the copper rod 200 toward the conditioning zone 113, the copper rod 200 first passes through the first preheating zone 114 and is preheated by the gas duct 111 within the first preheating zone 114. At the same time, the movement of the bracket 121 toward the adjustment area 113 will also drive the piston plate 131 to move. During the movement of the piston plate 131, the space in area a will be reduced. Since area b and area a are isolated by the piston plate 131, the exhaust gas in the air distribution chamber 105 can only be exhausted through the vent 110 corresponding to area a. In this way, since the number of vents 110 that can exhaust exhaust gas is reduced, the pressure of the high-temperature exhaust gas in area a is further increased. At this time, the pressure in the connecting pipe 141 connected to one of the vents 110 will also increase. When the pressure in the connecting pipe 141 is greater than the elastic force of the return spring 144, the high-temperature exhaust gas in the connecting pipe 141 pushes the second baffle 143 to move through the piston block 142, so that the second baffle 143 enters the moving path of the bracket 121, intercepts the bracket 121, and prevents the bracket 121 from moving.

[0043] When the end of the bracket 121 abuts the side wall of the second baffle 143, the ventilation pipe 150 communicates with the exhaust passage 124. At this time, the high-temperature exhaust gas in the air distribution chamber 105 enters the exhaust passage 124 through the gas collecting chamber 106 and the ventilation pipe 150, pushing the roller 122, causing it to rotate. As the roller 122 rotates, it drives the copper rod body 200 to rotate. Simultaneously, the roller 122 also drives the cam 123 to rotate. When the protruding end of the cam 123 rotates downward, the cam 123 presses the follower arm 134 downward, which drives the movable plate 133 downward, causing the opening 132 in the side wall of the movable plate 133 to communicate with the opening 132 in the side wall of the piston plate 131. At this time, area a and area b are connected through the opening 132. In this way, the high-temperature exhaust gas in region a can enter region b through opening 132, thereby reducing the pressure in region a. When the pressure in region a decreases, the return spring 144 elastically resets the piston block 142, causing the piston block 142 to drive the second baffle 143 away from the bracket 121. At this point, the second baffle 143 no longer blocks the bracket 121. Under the action of gravity, the bracket 121 continues to move toward the exit of the preheating channel 101. When the copper rod body 200 passes through the adjustment zone 113 and moves to the next preheating zone 114, the air guide 111 located in the preheating zone 114 continues to preheat the rotating copper rod body 200.

[0044] When the copper rod body 200 rests against the outlet of the preheating channel 101, the preheated copper rod body 200 is removed from the top of the bracket 121. At this point, the connecting spring 135 also uses its elastic force to move the movable plate 133 upward and reset. The upward movement of the movable plate 133 drives the follower arm 134, which moves upward and pushes the protruding end of the cam 123, causing the protruding end of the cam 123 to change direction. Simultaneously, due to the reduced weight of the bracket 121, the movable plate 133 resets, closing the opening 132. Therefore, the high-temperature exhaust gas in the gas distribution chamber 105 pushes the piston plate 131 toward one end of the preheating channel 101, causing the piston plate 131 to move the bracket 121 to the inlet of the preheating channel 101.

[0045] It should be noted that in order to increase the pressure of high-temperature exhaust gas, a turbo fan can be set in the air inlet 107, and the fan action can be used to increase the pressure in the air distribution cavity 105, so that the pressure in the air distribution cavity 105 can push the piston plate 131 to reset when the copper rod body 200 is not loaded.

[0046] It can be seen that, by setting up the air distribution cavity 105, the present invention not only realizes the rotation of the copper rod body 200 in the preheating channel 101, but also realizes that when the copper rod body 200 is separated from the copper rod carrier 120, the pressure in the air distribution cavity 105 is used to automatically drive the copper rod carrier 120 to reset, so that the copper rod carrier 120 can realize reciprocating motion in the preheating channel 101, thereby achieving continuous operation to preheat multiple copper rod bodies 200.

[0047] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
