Muffle traction device of carbonization furnace

Abstract

A muffle traction device of a carbonization furnace comprises a carbonization furnace body and a muffle, one end of the muffle is connected with the carbonization furnace body, and the other end of the muffle is connected with a traction device; the traction device comprises a frame; a sliding seat is connected above the frame in a sliding manner, and the end part of the muffle is fixed on the sliding seat; a rotating shaft is further rotationally connected to the frame; a winding disc is fixed on the rotating shaft; the winding disc is connected with the sliding seat through a steel wire rope; the side edge of the rotating shaft is further connected with a balancing weight. When the muffle is used, the steel wire rope always exerts outward pulling force on the sliding seat through the gravity of the balancing weight, so that when the muffle shrinks, the sliding seat always pulls the muffle outwards, and the muffle is always in a leveled state; when the muffle expands, the balancing weight drives the rotating shaft to rotate through the gravity of the balancing weight, the rotating shaft rotates and drives the winding disc to rotate at the same time, so that the steel wire rope is wound, at the moment, the sliding base moves outwards, the muffle is still leveled, and warping of the muffle is prevented.

Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber equipment, in particular to a muffle traction device for a carbonization furnace. Background Art

[0002] A carbonization furnace is a device for carbonizing pre-oxidized wire (or phenolic raw wire). Continuous furnaces are the main type, and intermittent furnaces are pre-oxidation furnaces, which are operated by increasing the temperature. A muffle is generally installed in the carbonization furnace body. In actual applications, as the temperature changes, the muffle is prone to thermal expansion and contraction. Specifically, the muffle will expand when heated and contract when cooled. During the expansion or contraction of the muffle, if the expansion or contraction is uneven, the muffle is prone to warping. Therefore, a muffle traction device for a carbonization furnace that can flatten the muffle is what we need, as it can prevent the muffle from warping. Utility Model Content

[0003] The utility model aims to solve the technical problem of providing a muffle traction device for a carbonizing furnace which can level the muffle.

[0004] In order to solve the above technical problems, the technical solution of a muffle traction device of a carbonizing furnace in the utility model is:

[0005] It includes a carbonization furnace body and a muffle connected to the carbonization furnace body, wherein one end of the muffle is connected to the carbonization furnace body, and the other end is connected to a traction device; the traction device includes a frame; a slide seat is slidably connected above the frame for pulling the muffle connected to the traction device outward, and the end of the muffle is fixed on the slide seat; the frame is also rotatably connected to a rotating shaft; a winding disk is fixed on the rotating shaft; the winding disk is connected to the sliding seat through a wire rope, and the winding disk pulls the sliding seat outward through the winding wire rope; the side of the rotating shaft is also connected to a counterweight block for driving the rotating shaft to rotate so as to control the winding wire rope of the winding disk.

[0006] The front and rear ends of the rotating shaft are both connected with winding disks, and the front and rear sides of the corresponding upper part of the frame are both slidably connected with sliding seats; the two winding disks are respectively connected to the two sliding seats through steel wire ropes.

[0007] A guide wheel is connected to the side of the frame; one end of the steel wire rope is connected to the slide seat, and the other end passes around the guide wheel and is wound on the winding drum.

[0008] The muffle is connected to the slide seat via an axle pin.

[0009] A transverse slide rail is connected above the frame; the slide seat is connected to the transverse slide rail in a transverse sliding manner.

[0010] The counterweight block is welded to the rotating shaft.

[0011] The technical effect achieved by the utility model is as follows: when the muffle traction device for a carbonizing furnace is in use, the weight of the counterweight block causes the steel wire rope to always exert a force pulling the slide seat outwards, so that when the muffle contracts, the slide seat always pulls the muffle outwards, so that the muffle is always in a flattened state; and when the muffle expands, the counterweight block drives the rotating shaft to rotate through its own gravity, and the rotating shaft drives the winding disk to rotate while rotating, thereby winding the steel wire rope, and at this time the slide seat moves outwards, and the muffle is still flattened, thereby preventing the muffle from warping.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] See also Figures 1 to 4 .

[0019] A muffle traction device for a carbonizing furnace comprises a carbonizing furnace body 11 and a muffle 1 connected to the carbonizing furnace body 11, wherein one end of the muffle 1 is connected to the carbonizing furnace body 11, and the other end is connected to the traction device; the traction device comprises a frame 10, the frame 10 is fixed to the ground by anchor bolts, a slide seat 4 is slidably connected above the frame 10 for pulling the muffle 1 outward at its connection end with the traction device, and the end of the muffle 1 is fixed to the slide seat 4; specifically, a transverse slide rail 6 is connected above the frame 10, the slide seat 4 is transversely slidably connected to the transverse slide rail 6, and the muffle 1 is connected to the transverse slide rail 6 by an axis The pin 2 is connected to the slide 4; the frame 10 is also rotatably connected to a rotating shaft 8, on which a winding drum 7 is fixed, the winding drum 7 is connected to the slide 4 through a wire rope 5, and the winding drum 7 pulls the slide 4 outward by winding the wire rope 5, and the side of the rotating shaft 8 is also connected to a counterweight block 9 for driving the rotating shaft 8 to rotate so as to control the winding of the wire rope 5 by the winding drum 7; specifically, the counterweight block 9 is welded to the rotating shaft 8; specifically, a guide wheel 21 is connected to the side of the frame 10, one end of the wire rope 5 is connected to the slide 4, and the other end passes around the guide wheel 21 and is wound on the winding drum 7.

[0020] The utility model is welded to the side of the shaft 8 by the counterweight block 9 when in use (refer to Figure 3 ), the counterweight 9 exerts a downward force on the side of the rotating shaft 8 due to gravity (refer to Figure 3 ), so that the reel 7 always has a reeling force on the wire rope 5, that is, the wire rope 5 always has a force to pull the slide 4 outwards. Therefore, when the muffle 1 contracts, the slide 4 always pulls the muffle 1 outwards, so that the muffle 1 is always in a flattened state; and when the muffle expands, the counterweight block 9 drives the rotating shaft 8 to rotate by its own gravity, and the rotating shaft 8 drives the reel 7 to reel the wire rope 5 while rotating. At this time, the slide 4 is pulled outward by the wire rope 5, and the muffle 1 will still be flattened, thereby preventing the muffle 1 from warping.

[0021] Specifically, the front and rear ends of the rotating shaft 8 of the utility model are connected to the winding drum 7, and the corresponding front and rear sides of the upper part of the frame 10 are slidably connected to the slide seats 4. The two winding drums 7 are respectively connected to the two slide seats 4 through the wire rope 5. The utility model flattens the muffle 1 through the slide seats 4 set at the front and rear.
