Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of furnace charge preheating, in particular to a multi-point heating copper rod processing furnace charge preheating equipment. BACKGROUND

[0002] As raw materials, copper rods or copper bars usually need to be subjected to secondary processing operations in use. Before being subjected to secondary processing, the copper rods as blanks usually need to be subjected to heating treatment to improve the plasticity of the copper rods, so as to facilitate subsequent operations such as stretching, extrusion and other secondary processing forming steps.

[0003] When the copper rod is subjected to such treatment, the commonly used heating method is flame heating. Specifically, the copper rod is first placed in a furnace body, and then a flame is introduced into the furnace body to heat the copper rod by using the high temperature of the flame. During the heating process, the high-temperature waste gas in the furnace body needs to be discharged to the outside. In order to utilize the high-temperature waste gas, the waste heat of the waste gas is usually utilized to preheat the copper rod, thereby improving the subsequent heating efficiency of the copper rod.

[0004] The current preheating method is mostly contact preheating, that is, the high-temperature waste gas is introduced into a preheating furnace to generate high temperature in the preheating furnace, and then the copper rod is placed on a base in the preheating furnace, and the copper rod is moved in the preheating furnace by the base, so as to preheat the copper rod.

DETAILED DESCRIPTION

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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 toFigure 3 As shown, the high part of the slope is the entrance, and the low part is the exit. In this way, the copper rod carrier 120 located at the entrance can move to the exit under the action of gravity. In order to reduce the loss of hot gas, the present application is provided with a first baffle plate 103 at the entrance and the exit, and the first baffle plate 103 is made of flexible material. When the copper rod body 200 passes through the entrance or the exit, the first baffle plate 103 will be deformed to allow the copper rod body 200 to pass through. In addition, other ways can also be used to block the entrance and the exit. For example, a hydraulic rod is arranged on the top of the first baffle plate 103, and the hydraulic rod is fixed on the top of the furnace body 100. When the copper rod body 200 passes through the entrance or the exit, the hydraulic rod drives the first baffle plate 103 to move upwards, so that the entrance and the exit can also be opened.

[0047] The preheating channel 101 is communicated with an exhaust pipe 102 penetrating through the top of the furnace body 100, for discharging the gas in the preheating channel 101.

[0048] As shown in Figure 2 The inside of the furnace body 100 and the outside of the preheating channel 101 are hollow structures. A first partition plate 104 is arranged at the bottom of the preheating channel 101, which separates the lower part of the inside of the furnace body 100 into a gas distribution cavity 105, and separates the upper part into a gas collection cavity 106. One end of the gas distribution cavity 105 is communicated with a gas inlet 107 (combined with Figure 1 As shown, the high part of the slope is the entrance, and the low part is the exit. In this way, the copper rod carrier 120 located at the entrance can move to the exit under the action of gravity. In order to reduce the loss of hot gas, the present application is provided with a first baffle plate 103 at the entrance and the exit, and the first baffle plate 103 is made of flexible material. When the copper rod body 200 passes through the entrance or the exit, the first baffle plate 103 will be deformed to allow the copper rod body 200 to pass through. In addition, other ways can also be used to block the entrance and the exit. For example, a hydraulic rod is arranged on the top of the first baffle plate 103, and the hydraulic rod is fixed on the top of the furnace body 100. When the copper rod body 200 passes through the entrance or the exit, the hydraulic rod drives the first baffle plate 103 to move upwards, so that the entrance and the exit can also be opened.

[0049] In order to prevent heat loss to the outside through the furnace body 100, the present application carries out heat insulation treatment on the furnace body 100. Specifically, a heat insulation layer 108 is arranged on the inner wall of the furnace body 100, which is, for example, an aluminum silicate blanket, heat insulation cotton, etc.

[0050] As shown in Figure 3 The inside of the furnace body 100 and the outside of the preheating channel 101 are hollow structures. A first partition plate 104 is arranged at the bottom of the preheating channel 101, which separates the lower part of the inside of the furnace body 100 into a gas distribution cavity 105, and separates the upper part into a gas collection cavity 106. One end of the gas distribution cavity 105 is communicated with a gas inlet 107 (combined with Figure 4), for separating the space inside the gas collecting cavity 106. The number of the second partitions 112 can be one or more. 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, so as to separate the inside of the gas collecting cavity 106 into three spaces that are not communicated with each other. Meanwhile, the plurality of air vents 110 are arranged corresponding to the three spaces, i.e. there is an air vent 110 at each space (see the position of the air vent 110 in FIG. 4), so that the high-temperature exhaust gas in the gas distribution cavity 105 can enter into different spaces through different air vents 110. 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, so as to separate the inside of the gas collecting cavity 106 into three spaces that are not communicated with each other. Meanwhile, the plurality of air vents 110 are arranged corresponding to the three spaces, i.e. there is an air vent 110 at each space (see the position of the air vent 110 in FIG. 4), so that the high-temperature exhaust gas in the gas distribution cavity 105 can enter into different spaces through different air vents 110. Figure 3

[0051] In addition, the part of the preheating channel 101 inside corresponding to the two second partitions 112 forms an adjusting area 113, and the two ends form preheating areas 114. Meanwhile, the gas guide pipe 111 is arranged in the preheating area 114. Then, the bottom of the preheating channel 101 is provided with a copper bar carrier 120 for driving the copper bar body 200 to move in the preheating channel 101, and the copper bar carrier 120 includes a plurality of rotating rollers 122 supported on the bottom of the copper bar body 200. Moreover, the adjusting area 113 is provided with a driving part communicated with the gas collecting cavity 106, and the gas distribution cavity 105 is provided with a gas pressure adjusting member 130 for controlling the pressure change inside the gas distribution cavity 105. When the copper bar carrier 120 moves, the gas pressure adjusting member 130 increases the pressure in front of the copper bar carrier 120 in the gas distribution cavity 105, and when the copper bar carrier 120 moves into the adjusting area 113, the driving part drives the rotating roller 122 to rotate under the action of the increased pressure, so as to make the rotating roller 122 drive the copper bar body 200 to overturn in the adjusting area 113, thereby realizing uniform preheating of the copper bar body 200.

[0052] In the embodiment shown, the gas pressure adjusting member 130 includes a piston plate 131 fixedly connected with the copper bar carrier 120, and the side wall of the piston plate 131 is provided with a closable through port 132. When the copper bar carrier 120 drives the piston plate 131 to move, the through port 132 is in a closed state, so as to increase the pressure in front of the piston plate 131 in the gas distribution cavity 105. Figure 7

[0053] That is to say, by using the rotating roller 122 to support the copper bar body 200, when the copper bar body 200 moves to the adjusting area 113, the high pressure in the gas distribution cavity 105 drives the rotating roller 122 to rotate through the driving part, so as to make the copper bar body 200 above the rotating roller 122 rotate together, thereby realizing the change of the contact position between the copper bar body 200 and the copper bar carrier 120, and improving the preheating efficiency of the copper bar body 200.

[0054] In the embodiment shown, the gas pressure adjusting member 130 includes a piston plate 131 fixedly connected with the copper bar carrier 120, and the side wall of the piston plate 131 is provided with a closable through port 132. When the copper bar carrier 120 drives the piston plate 131 to move, the through port 132 is in a closed state, so as to increase the pressure in front of the piston plate 131 in the gas distribution cavity 105. Figures 3-5 ​​As shown, a limiting piece 140 is arranged in the adjusting area 113, which includes a connecting pipe 141 extending to one side of the moving direction of the copper bar carrier 120 and communicating with one of the air vents 110 at one end, a piston block 142 slidingly connected at one end inside the connecting pipe 141 at one end of the connecting pipe 141 at one side of the moving direction of the copper bar carrier 120, a second baffle 143 fixedly connected to the side wall of one end of the piston block 142 and extendable into the moving path of the copper bar carrier 120, and a reset spring 144 arranged between the one end of the piston block 142 and the end of the connecting pipe 141 to elastically connect the two. In the normal state, the reset spring 144 limits the second baffle 143 outside the moving path of the copper bar carrier 120. The second baffle 143 is in a plate structure and rotatably provided with a roller on the side facing the bracket 121, which can reduce the friction between the bracket 121 and the second baffle 143 to facilitate the movement of the second baffle 143.

[0055] As shown in Figure 7 and Figure 8 , the copper bar carrier 120 includes a bracket 121 slidingly arranged at the bottom of the preheating channel 101 along the length direction of the furnace body 100, which is in a box-like structure with an opening at the top and downwardly recessed opposite side walls for placing the copper bar body 200; the shaft rods are coaxially fixedly connected to the two ends of the rotating roller 122, and the rotating roller 122 is rotatably arranged at the two sides of the bracket 121 through the shaft rods; and the shaft rod at one end of one of the rotating rollers 122 is fixedly provided with a cam 123. On the other hand, the top of the rotating roller 122 is higher than the top of the bracket 121 to prevent the copper bar body 200 from contacting the top of the bracket 121. Also, as shown in Figure 8 , the inner wall of the bracket 121 close to the rotating roller 122 is in contact with the outer ring of the rotating roller 122, which can prevent the gas from being discharged to cooperate with the exhaust channel 124 to be described in detail next.

[0056] The exhaust channel 124 is arranged through one side of the bracket 121, and the through part is preferably above or below the center of the rotating roller 122. In the embodiment shown in Figure 8 , the through part is below the center of the rotating roller 122, so that Figure 8 , taking the state of the rotating roller 122 as an example, when the gas enters the exhaust channel 124, the gas will push the rotating roller 122 to rotate in the clockwise direction.

[0057] It should be noted that the outer ring of the rotating roller 122 is provided with a plurality of grooves to form a toothed shape, so that the gas in the exhaust channel 124 can push the rotating roller 122 to rotate.

[0058] There are various ways for the bracket 121 to slide at the bottom of the preheating channel 101, for example, in Figure 2 and Figure 7In the shown embodiment, the bottom of the bracket 121 is protruded downward to form a slide bar, which is parallel to the length direction 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 direction of the furnace body 100; in this way, the slide bar is arranged in the slide rail, so as to realize the sliding connection between the bracket 121 and the bottom of the preheating channel 101. In addition, in other embodiments, a rotating wheel, a ball or the like can be arranged at the bottom of the bracket 121, as long as the movement of the bracket 121 at the bottom of the preheating channel 101 is realized.

[0059] In Figure 6 and Figure 7 , the bottom of the preheating channel 101 and the bottom of the first partition plate 104 are both provided with a through groove 109, which is parallel to the length direction of the furnace body 100; the middle of the top of the piston plate 131 is protruded upward to form a connecting block, which is fixedly connected to the bottom of the bracket 121 after passing through the through groove 109.

[0060] The side wall of the piston plate 131 is longitudinally and slidably connected with a movable plate 133; a plurality of through openings 132 are longitudinally arranged, and the through openings 132 pass through the piston plate 131 and the movable plate 133; the top of the movable plate 133 is fixedly provided with a driven arm 134, which extends to below the cam 123; a connecting spring 135 is arranged between the top of the movable plate 133 and the side wall of the piston plate 131, and elastically connects the two. In the normal state, the through openings 132 of the side wall of the movable plate 133 are in a misaligned state with the through openings 132 of the side wall of the piston plate 131.

[0061] In the above, the reset spring 144 and the connecting spring 135 are preferably made of a high-temperature-resistant material, such as ceramic.

[0062] It should be noted that the protruding end of the cam 123 is in a triangular state, and the top end of the driven arm 134 is also in a triangular state. In this way, the contact area between the top end of the driven arm 134 and the protruding end of the cam 123 is small, so that the protruding end of the cam 123 will not be stuck at the top of the driven arm 134, so that the connecting spring 135 can drive the movable plate 133 to move upward and reset.

[0063] As shown in Figure 3 and Figure 4 , the driving part is a ventilation pipe 150 fixedly arranged on the inner wall of the preheating channel 101, in Figure 3 the shown embodiment, one end of the ventilation pipe 150 communicates with the gas collecting cavity 106, and the other end is attached to the side wall of the bracket 121; when the end of the bracket 121 abuts against the side wall of the second baffle 143, the ventilation pipe 150 communicates with the exhaust channel 124.

[0064] Working principle:

[0065] In combination with Figures 9-11As shown, the high-temperature exhaust gas enters into the air distribution cavity 105 through the air inlet 107, then enters into the air collection cavity 106 through the air passage 110, and finally enters into the preheating channel 101 through the air guide pipe 111 and is discharged through the air outlet pipe 102. Since the high-temperature exhaust gas has a high pressure, the high-pressure exhaust gas in the air distribution cavity 105 will push the piston plate 131 to the one end of the preheating channel 101, so that the piston plate 131 drives the bracket 121 to move to the one end of the preheating channel 101 (i.e. the inlet).

[0066] When the copper rod body 200 is placed on the top of the rotating roller 122, since the copper rod body 200 has a large weight, the weight of the copper rod body 200 will act on the bracket 121, so that the piston plate 131 at the bottom of the bracket 121 overcomes the pressure of the high-temperature exhaust gas in the air distribution cavity 105 and moves to the other end of the preheating channel 101 (i.e. the outlet). When the bracket 121 drives the copper rod body 200 to move to the adjusting area 113, the copper rod body 200 will first pass through the first preheating area 114 and is preheated through the air guide pipe 111 in the first preheating area 114. At the same time, the movement of the bracket 121 to the adjusting area 113 also drives the piston plate 131 to move. During the movement of the piston plate 131, the space of the area a will decrease. Since the area b is isolated from the area a by the piston plate 131, the exhaust gas in the air distribution cavity 105 can only be discharged through the air passage 110 corresponding to the area a. In this way, since the number of the air passages 110 through which the exhaust gas can be discharged decreases, the pressure of the high-temperature exhaust gas in the area a is further increased. At this time, the pressure in the connecting pipe 141 connected with one of the air passages 110 is also increased. 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 through the piston block 142 to move, so that the second baffle 143 enters the movement path of the bracket 121 and intercepts the movement of the bracket 121, so that the bracket 121 cannot move.

[0067] When the end of the support 121 abuts against the side wall of the second baffle 143, the ventilation pipe 150 will be in communication 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 air collection chamber 106 and the ventilation pipe 150, and pushes the rotating roller 122 to rotate. When the rotating roller 122 rotates, the rotating roller 122 drives the copper bar body 200 to rotate, and at the same time, the rotating roller 122 also drives the cam 123 to rotate, when the protruding end of the cam 123 rotates downward, the cam 123 presses the driven arm 134 downward, the driven arm 134 drives the movable plate 133 to move downward, so that the through hole 132 in the side wall of the movable plate 133 is in communication with the through hole 132 in the side wall of the piston plate 131, at this time, the region a and the region b are in communication through the through hole 132. In this way, the high-temperature exhaust gas in the region a can enter the region b through the through hole 132, so as to reduce the pressure in the region a, when the pressure in the region a is reduced, the reset spring 144 drives the piston block 142 to reset through the elasticity, so that the piston block 142 drives the second baffle 143 to disengage from the support 121. At this time, the second baffle 143 no longer blocks the support 121. Under the action of gravity, the support 121 continues to move to the outlet of the preheating passage 101, when the copper bar body 200 moves to the next preheating zone 114 after passing through the adjusting zone 113, the air guide pipe 111 located at the preheating zone 114 continues to preheat the copper bar body 200 after rotating.

[0068] When the copper bar body 200 abuts against the outlet of the preheating passage 101, the copper bar body 200 preheated is taken out from the top of the support 121. At this time, the connecting spring 135 also drives the movable plate 133 to move upward and reset through the elastic force, the movable plate 133 moves upward drives the driven arm 134, the driven arm 134 moves upward drives the protruding end of the cam 123, so that the protruding end of the cam 123 changes direction. At the same time, due to the reduction of the weight of the support 121, the reset of the movable plate 133 makes the through hole 132 closed, therefore, the high-temperature exhaust gas in the air distribution chamber 105 can push the piston plate 131 to move to one end of the preheating passage 101, so that the piston plate 131 drives the support 121 to move to the inlet end of the preheating passage 101.

[0069] It should be noted that in order to improve the pressure of the high-temperature exhaust gas, a turbine fan can be arranged in the air inlet 107, and the fan is used to improve the pressure in the air distribution chamber 105, so that the pressure in the air distribution chamber 105 can push the piston plate 131 to reset when the copper bar body 200 is not loaded.

[0070] Therefore, through the air distribution cavity 105, the copper bar body 200 can rotate in the preheating channel 101, and when the copper bar body 200 is separated from the copper bar carrier 120, the copper bar carrier 120 can be automatically driven to reset by the pressure in the air distribution cavity 105, so that the copper bar carrier 120 can realize reciprocating motion in the preheating channel 101, thereby achieving continuous operation to preheat multiple copper bar bodies 200.
