Description

Technical Field

[0001] The invention belongs to the technical field of carbon fiber oxidation furnaces, and in particular relates to a fresh air filtering device for a carbon fiber oxidation furnace. Background Art

[0002] PAN-based carbon fiber has the characteristics of high specific strength, high specific modulus, high temperature resistance, fatigue resistance, creep resistance, conductivity, heat insulation and small thermal expansion coefficient. It is a new type of carbon material with comprehensive excellent performance. It is widely used in aviation, aerospace, chemical, construction and sporting goods industries. When the oxidation furnace oxidizes the carbon fiber, a fresh air circulation device is required, which not only does not destroy the isothermal zone in the furnace, but also achieves the purpose of supplying oxygen to the furnace.

[0003] A Chinese patent with application number 202320675702.4 discloses a fresh air filtering device, in which fresh air is filtered through a coarse filter and a fine filter in a docking frame. The docking frame is bolted on the mounting frame to facilitate the later disassembly and replacement of the coarse filter and the fine filter. When a large amount of dust is attached to one side of the coarse filter and the fine filter, the electromagnetic vibrator is started, and the electromagnetic vibrator will drive the mounting frame to vibrate. The vibrating mounting frame will vibrate synchronously with the docking frame and the coarse filter and the fine filter. The dust attached to the coarse filter and the fine filter is shaken off by high-frequency vibration, making it less likely to be blocked and convenient for personnel to clean.

[0004] However, the above technical solution has certain shortcomings. When high-frequency vibration is used to shake off the dust attached to the coarse filter and the fine filter, since the dust is a macroscopic object, it will flow with the high-density air to the low-density place, causing the dust to fly and be easily inhaled by the staff, affecting their health.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] As Figures 1 to 7 shown, the present invention provides a fresh air filtering device for a carbon fiber oxidation furnace, including: a filtering component and a connecting seat 170, and the filtering component is slidably connected to the connecting seat 170.

[0050] Furthermore, the connecting seat 170 is fixedly provided with vibration dust suppression components 110, and the vibration dust suppression components 110 are located on opposite sides of the filtering component;

[0051] The vibration dust suppression components 110 are connected to the filtering component through multiple groups of connecting rods 111.

[0052] In this embodiment, the fresh air filtering device for the carbon fiber oxidation furnace includes a filtering component and a connecting seat 170, and the filtering component is slidably arranged on the front surface of the connecting seat 170. Specifically, as Figure 2 and Figure 6 shown, a connecting block 150 is fixedly installed on the rear surface of the filtering component, and a sliding groove 160 is opened at a position corresponding to the connecting block 150 on the front surface of the connecting seat 170. The connecting block 150 is placed in the sliding groove 160 to realize the sliding of the filtering component relative to the connecting seat 170. When the filtering component moves left and right, the connecting block 150 arranged behind the filtering component slides inside the sliding groove 160 opened on the front surface of the connecting seat 170, thereby achieving the effect of the left and right movement of the filtering component.

[0053] In this embodiment, vibration dust suppression components 110 are fixedly installed on opposite sides of the filtering component on the front surface of the connecting seat 170, so two vibration dust suppression components 110 are fixedly provided on the front surface of the connecting seat 170. Taking one of the vibration dust suppression components 110 as an example, it is connected to the filtering component through two symmetric connecting rods 111 up and down. Specifically, as Figure 2As shown in the figure, a fixing plate 1111 is provided on the front surface of the connecting seat 170. The vibration dust suppression component 110 is installed on the connecting seat 170 through the fixing plate 1111. Similarly, the vibration dust suppression component 110 on the other side is installed on the connecting seat 170 in the same way and is connected to the filtering component in the same way.

[0054] Furthermore, the vibration dust suppression component 110 is provided with a piston chamber 113. The connecting rod 111 extends into the piston chamber 113, and a piston 114 is provided at the end. The piston 114 moves within the piston chamber 113.

[0055] A first spring 112 is sleeved on the connecting rod 111. The two ends of the first spring 112 are respectively connected to the filtering component and the vibration dust suppression component 110.

[0056] In this embodiment, a piston chamber 113 is provided at the position of the vibration dust suppression component 110 relative to the connecting rod 111. One end of the connecting rod 111 is connected to the filtering component, and the other end extends into the piston chamber 113. A piston 114 is provided at the end of the connecting rod 111 extending into the piston chamber 113. The piston 114 moves in the left - right direction within the piston chamber 113. A first spring 112 is sleeved on the connecting rod 111. One end of the first spring 112 is connected to the filtering component, and the other end is connected to the vibration dust suppression component 110.

[0057] Specifically, the filtering component moves left - right relative to the connecting seat 170 and drives the connecting rod 111 to move through the filtering component. When the filtering component moves to the right, the piston 114 on the right - hand connecting rod 111 moves to the right within the corresponding piston chamber 113 and compresses the first spring 112 on the right - hand connecting rod 111. At the same time, the piston 114 on the left - hand connecting rod 111 moves to the right within the corresponding piston chamber 113 and stretches the first spring 112 on the left - hand connecting rod 111. When the filtering component moves to the left, the piston 114 on the left - hand connecting rod 111 moves to the left within the corresponding piston chamber 113 and compresses the first spring 112 on the left - hand connecting rod 111. At the same time, the piston 114 on the right - hand connecting rod 111 moves to the left within the corresponding piston chamber 113 and stretches the first spring 112 on the right - hand connecting rod 111. Through the action of the driving device and the first spring 112, the left - right sliding of the filtering component relative to the connecting seat 170 is realized.

[0058] Furthermore, the vibration dust suppression component 110 is provided with a detachable filter box 118, and a detachable filter cloth 119 is provided inside the filter box 118.

[0059] On the side of the vibration dust suppression component 110 facing the filtering component, a dust inlet 1110 is provided. The dust inlet 1110 is communicated with the filter box 118 through a pipeline.

[0060] In this embodiment, a plurality of filter boxes 118 are provided in the vibration dust suppression assembly 110. The filter boxes 118 can be taken out from the side of the vibration dust suppression assembly 110 facing away from the filter assembly for cleaning or replacement. A filter cloth 119 is provided inside the filter box 118. The filter cloth 119 is horizontally arranged in the filter box 118 in a detachable manner by bolts. An air inlet 1110 is provided on the side of the vibration dust suppression assembly 110 facing the filter assembly. On the filter box 118, a pipe hole is provided at a position corresponding to the air inlet 1110. A pipeline is provided between the air inlet 1110 and the pipe hole. The flying dust enters the pipeline through the air inlet 1110 and then enters the filter box 118 through the pipe hole. To prevent the leakage of flying dust at the pipe hole, a soft rubber ring is provided on the inner wall of the pipe hole to seal the pipe hole.

[0061] Further, the vibration dust suppression assembly 110 is provided with: a plurality of receiving grooves, a suction pipe 116 and a discharge pipe 117. The suction pipe 116 and the discharge pipe 117 are respectively arranged in the corresponding receiving grooves;

[0062] The suction pipe 116 communicates with the filter box 118 and the piston chamber 113. A check valve 115 is provided at one end of the suction pipe 116 communicating with the piston chamber 113;

[0063] One end of the discharge pipe 117 communicates with the piston chamber 113, and the other end extends to the outside of the vibration dust suppression assembly 110. A check valve 115 is provided at one end of the discharge pipe 117 communicating with the piston chamber 113.

[0064] In this embodiment, the vibration dust suppression assembly 110 is provided with a plurality of receiving grooves, a suction pipe 116 and a discharge pipe 117. The suction pipe 116 and the discharge pipe 117 are respectively arranged in the corresponding receiving grooves. A first receiving groove is provided above the piston chamber 113. The discharge pipe 117 is placed in the first receiving groove. One end of the discharge pipe 117 communicates with the piston chamber 113, and the other end extends to the outside of the vibration dust suppression assembly 110 to discharge the gas in the piston chamber 113 out of the vibration dust suppression assembly 110. A check valve 115 is provided at the connection end of the discharge pipe 117 and the piston chamber 113. The check valve 115 can ensure that the gas in the piston chamber 113 is discharged through the discharge pipe 117 without allowing the external gas to enter the piston chamber 113 through the discharge pipe 117.

[0065] In this embodiment, a second receiving groove is provided between the piston chamber 113 and the filter box 118. An inhalation pipe 116 is placed in the second receiving groove, and the inhalation pipe 116 pumps the gas in the filter box 118 into the piston chamber 113. Specifically, the inhalation pipe 116 is a three-way pipe provided with two inlets and one outlet. The two inlets are respectively connected to two positions before and after the filter box 118, which can increase the amount of gas entering the inhalation pipe 116 so as to quickly inhale the gas in the filter box 118 into the piston chamber 113. The outlet is communicated with the piston chamber 113, and a check valve piece 115 is also provided at the connection between the inhalation pipe 116 and the piston chamber 113 to ensure that the gas in the filter box 118 can enter the piston chamber 113 through the inhalation pipe 116 and will not enter the filter box 118 from the piston chamber 113.

[0066] It should be noted that the above is only an example with one filter box 118, piston chamber 113, the receiving groove adjacent to the filter box 118 and the piston chamber 113, and the inhalation pipe 116 and discharge pipe 117 arranged in the corresponding receiving groove. The settings of the remaining filter boxes 118, piston chambers 113, receiving grooves, inhalation pipes 116 and discharge pipes 117 are the same as the above settings.

[0067] Further, the filter assembly includes: a mounting frame 100, a vibration motor 1112 is provided on the mounting frame 100, and the vibration motor 1112 drives the filter assembly to slide relative to the connecting seat 170;

[0068] A positioning frame 130 is fixedly installed in the mounting frame 100;

[0070] Further, a driving device 133 is provided on the mounting frame 100, and the output end of the driving device 133 is connected to a reciprocating lead screw 131.

[0071] The reciprocating lead screw 131 extends into the positioning frame 130, and the end is rotatably connected to the bottom end of the positioning frame 130;

[0074] Both ends of the brush strip 135 are respectively provided with a first moving block 132 and a second moving block 136. Among them, the first moving block 132 is threadedly connected to the reciprocating lead screw 131; the second moving block 136 is slidably connected to the slide bar 137.

[0075] In this embodiment, the filter assembly wraps the installation frame 100. A positioning frame 130 is fixedly provided inside the installation frame 100. A filter plate 140 is installed on the front surface of the positioning frame 130, and the filter plate 140 slides longitudinally inside the installation frame 100. A driving device 133 is installed on the installation frame 100. Here, the driving device 133 is a motor. Specifically, the driving device 133 is arranged on the upper surface of the installation frame 100. The output end of the driving device 133 is connected to a reciprocating lead screw 131. The reciprocating lead screw 131 extends downward into the positioning frame 130, and the end is connected to the bottom end of the positioning frame 130 through a bearing. The circumference of the reciprocating lead screw 131 is provided with threads.

[0076] In this embodiment, on the positioning frame 130, on the other side opposite to the side where the reciprocating lead screw 131 is arranged, there is a slide bar 137. The slide bar 137 is arranged parallel to the reciprocating lead screw 131. A brush strip 135 is provided between the positioning frame 130 and the filter plate 140.

[0077] In this embodiment, when cleaning the filter plate 140, the driving device 133 is started. The driving device 133 drives the reciprocating lead screw 131 to rotate. At this time, the first moving block 132 realizes movement on the reciprocating lead screw 131 through the cooperation of the threads provided on the inner circumference and the threads provided on the outer circumference of the reciprocating lead screw 131; at the same time, the second moving block 136 slides on the slide bar 137, so as to realize the up and down movement of the brush strip 135 and realize the sweeping of the dust on the filter plate 140.

[0078] Further, on opposite sides of the installation frame 100, there is a disassembly and assembly component 120. The disassembly and assembly component 120 is provided with a pair of fixed rods 122. One end of the fixed rod 122 is fixedly connected to the installation frame 100, and the other end is provided with a limit block 123.

[0079] Further, the disassembly and assembly component 120 is provided with:

[0080] A moving plate 121, the moving plate 121 is movably arranged on a pair of the fixed rods 122;

[0081] A second spring 124, which is sleeved on the fixed rod 122 and has two ends respectively connected to the limit block 123 and the moving plate 121.

[0082] Further, the moving plate 121 is provided with a clamping plate 126, and the filter plate 140 is provided with a clamping groove 127. The clamping plate 126 passes through the installation frame 100 and is inserted into the clamping groove 127 of the filter plate 140; on the other side of the moving plate 121 opposite to the clamping plate 126, a pull handle 125 is provided.

[0083] In this embodiment, as Figures 1 to 7 shown, the vibration dust suppression assembly 110 is arranged on the left and right sides of the installation frame 100, and a disassembly and assembly component 120 is arranged on the upper and lower surfaces of the installation frame 100. The disassembly and assembly of the filter plate 140 is realized through the disassembly and assembly component 120. The disassembly and assembly component 120 includes a pair of fixed rods 122. One end of the fixed rod 122 is fixed on the installation frame 100, and the other end is provided with a limit block 123; a moving plate 121 is movably arranged on the pair of fixed rods 122, that is, the moving plate 121 is rectangular, and through holes are symmetrically arranged at corresponding positions at both ends in the length direction of the moving plate 121, and the moving plate 121 is sleeved on the pair of fixed rods 122 through the arranged through holes.

[0084] In this embodiment, a second spring 124 is arranged on the fixed rod 122, specifically between the limit block 123 of the fixed rod 122 and the moving plate 121. Two ends of the second spring 124 are respectively connected to the limit block 123 and the moving plate 121. A clamping plate 126 is arranged on the lower surface of the moving plate 121. The clamping plate 126 passes through the installation frame 100 and extends to the filter plate 140. A clamping groove 127 is arranged at the position of the filter plate 140 corresponding to the clamping plate 126, and the clamping plate 126 of the moving plate 121 is inserted into the clamping groove 127. A pull handle 125 is arranged on the other side of the moving plate 121 opposite to the clamping plate 126. The disassembly and assembly component 120 can be disassembled and assembled from the installation frame 100 through the pull handle 125, and thus the disassembly and assembly of the filter plate 140 are realized.

[0085] Specifically, by pulling the pull handle 125 of the disassembly component arranged on the upper and lower sides of the installation frame 100, the pull handle 125 drives the moving plate 121 to move on the fixed rod 122 and compresses the second spring 124, and then the moving plate 121 drives the clamping plate 126 to disengage from the clamping groove 127 arranged on the filter plate 140, thereby realizing the disassembly of the filter plate 140. When the filter plate 140 needs to be installed, only the pull handle 125 needs to be pulled. When the filter plate 140 enters the appropriate position inside the installation frame 100, then the pull handle 125 is released. The second spring 124 restores its elastic deformation to drive the clamping plate 126 to enter the clamping groove 127 arranged on the filter plate 140, thereby completing the installation. The installation and disassembly are convenient and fast, which is convenient for the staff to replace.

[0086] In this embodiment, when the fresh air filtering device of the carbon fiber oxidation furnace is in use, when filtering fresh air through the filter plate 140, since dust will adhere to the filter plate 140, it is likely to cause blockage and is not convenient for cleaning. By starting the vibration motor 1112, the vibration motor 1112 drives the mounting frame 100 to move left and right, and drives the connecting rod 111 through the mounting frame 100, and squeezes the first spring 112, so that the mounting frame 100 vibrates at a high frequency left and right, and shakes off the dust adhering to the filter plate 140 through high-frequency vibration. At the same time, the piston 114 is driven by the connecting rod 111 to move to the right inside the piston chamber 113. At this time, the one-way piece 115 at the end of the suction pipe 116 opens, so as to generate suction to suck the raised dust from the dust inlet 1110 into the inside of the filter box 118. The dust is filtered by the filter cloth 119, and the dust will fall into the filter box 118 due to its own gravity. The piston 114 moves to the left inside the piston chamber 113, and the square one-way piece 115 at the end of its discharge pipe 117 opens. The gas entering the piston chamber 113 is discharged from the discharge pipe 117. Subsequently, the operator only needs to pull out the filter box 118 to clean the filter cloth 119, thus preventing the filter plate 140 from being blocked, which is not convenient for the staff to clean, and suppressing the raising of dust, avoiding the inhalation of the staff.

[0087] When in use for a long time or when the filter plate 140 needs to be replaced, only by pulling the pull handles 125 on the upper and lower sides, the pull handles 125 drive the moving plate 121 to move on the fixed rod 122 and squeeze the second spring 124. Then, the moving plate 121 drives the clamping plate 126 to disengage from the card slots 127 on both sides of the filter plate 140, thus realizing the disassembly of the filter plate 140. When the filter plate 140 needs to be installed, only pull the pull handle 125. When the filter plate 140 enters the appropriate position inside the mounting frame 100, then release the pull handle 125.
