Description
Technical Field
The invention relates to a winding device for a plate-strip product, in particular to a winding device for a corrugated plate type flame arrester filter element.
Background
The flame arrester for pipeline is a safety device for preventing the flame of inflammable gas from spreading, and is mainly composed of a casing and a filter element. The filter element is a main component for preventing flame propagation, and a metal mesh filter element and a corrugated plate filter element are commonly used. The corrugated plate type filter element is a core component of the corrugated plate type flame arrester, is in a round cake shape, is formed by winding a flat steel belt and a corrugated steel belt after being superposed (the flat steel belt is positioned on the outer side of the corrugated steel belt), and compared with a metal mesh filter element, the corrugated plate type filter element can prevent fierce flame of deflagration, can bear corresponding mechanical and thermal effects, has small flow resistance and is easy to clean and replace.
In order to achieve the function of flame retarding of the filter element, the working principle of the flame arrester has two explanations: one is based on heat transfer and the other is based on wall effects. According to the principle of heat transfer, the flame passes through the tiny passage of the flame retardant element and is cooled in the passage, and when the flame is divided to a certain degree, the heat removed through the passage is enough to reduce the temperature below the ignition point of the combustible substance, so that the flame is extinguished. According to the wall effect, when the channel is narrow to a certain extent, collision of radicals with the wall of the pipe is dominant, the radicals are greatly reduced, and the combustion reaction cannot proceed. The size of the passage of the flame arrester element (i.e. the maximum experimental safety gap MESG) is therefore a critical factor in determining the performance of the flame arrester. Different gases have different MESG values, and gases are generally divided into four classes internationally according to the MESG value: IIC, IIB, IIA and I. It can be seen that the filter element assembly in the flame arrester is a key component for determining whether the whole flame arrester can achieve the flame arresting effect, and not only is the filter element assembly required to have certain rigidity on the whole to resist the strong impact of the shock wave formed by the explosion flame transmitted at subsonic or supersonic speed, but also the pressure drop of the gas during passing is required to be as small as possible; more importantly, the MESG value requirement of the flame arrester is met, namely, the size of each small channel is not larger than the maximum test safety gap as much as possible, so that each flame can be extinguished at the filter element to prevent the flame from further spreading. In order to achieve the purpose, extremely high quality requirements are provided for the filter element, and the actual efficiency of the filter element can be directly influenced by the winding quality of the filter element.
At present, filter elements of most domestic corrugated plate type flame arresters on the market are basically wound in a simple mechanical winding mode, the winding mode is similar to a manual workshop mode, the winding tightness is not enough, gaps are different in size, and the quality is not too high. Some manufacturers also have special winding tools, but the automation degree is low, and the winding efficiency is low.

(3) the two manual reversing air valves 64 are operated, so that the piston rods of the two second air cylinders 61 drive the two first rotary rods 51 to rotate towards the center of the main rotary disc 2 to approach, the pressing wheel 53 approaches the filter element center ring 20, the quick-tightening handle 52 is rotated, the spring 55 is pressed, and a vertical downward acting force is provided for the pressing wheel 53 through the spring 55, so that the pressing wheel 53 vertically presses the flat steel belt 33;
(4) starting the motion controller, enabling the servo motor to work, enabling the main turntable 2 to start to rotate, feeding the corrugated steel strip 34 on the other raw material turntable 3 into the flat steel strip 33 on the main turntable 2 after rotating for 1-2 circles, and then automatically completing the rest work under the control of the motion controller, wherein the rest work comprises flattening of the finishing end of the corrugated steel strip 34 (the flattening process is schematically shown in figure 8), shearing, spot welding of the finishing end and the like, in addition, in the winding process, the first revolving rod 51 drives the pressing wheels 53 to gradually move to the radial outer sides of the filter element discs along with the increase of the winding diameter of the filter element discs, after the winding is finished, the two pressing wheels 53 are moved away, the pressing wheels 53 and the pressing bolts 73 are loosened, and the wound filter element disc finished products can be taken down from the main turntable 2.
Fig. 8 is a schematic view of the flattening process of the finishing end of the corrugated steel strip 34, and the arrow in fig. 8 indicates the direction of rotation of the eccentric pressing roller 84. Before the flattening operation is not started, in the normal winding process, a 6mm gap is left between two eccentric press rolls 84 (as shown in fig. 8 a), the corrugated steel strip 34 does not affect to pass through the middle, when the corrugated steel strip 34 needs to be flattened, the direct current speed reduction motor 81 works to drive one wheel shaft 85, so that two transmission gears 83 drive the two eccentric press rolls 84 to make synchronous forward and reverse rotation movement, the effect of locally flattening the corrugated steel strip 34 is achieved through the distance change between the two eccentric press rolls 84, namely, the gap between the two eccentric press rolls 84 is gradually reduced (as shown in fig. 8 b) along with the rotation of the two eccentric press rolls 84, the corrugations on the corrugated steel strip 34 are gradually flattened (as shown in fig. 8c and 8 d), the gap between the two eccentric press rolls 84 is gradually increased (as shown in fig. 8 e) after the two eccentric press rolls 84 rotate for a certain angle, after the two eccentric press rolls 84 rotate for a period, the direct current speed reducing motor 81 stops working, the corrugated steel strip 34 is continuously conveyed forward for a certain distance to the steel strip shears, the rolled flat part can be cut off, and the requirements of rolling the head end and the tail end of the corrugated steel strip 34 are met.
