Description

Technical Field

[0001] This utility model relates to the field of polyimide slurry production, and in particular to a polyimide slurry filter. Background Technology

[0002] Polyimide paste has outstanding high temperature resistance, radiation resistance, chemical corrosion resistance and electrical insulation properties. It can be used for a long time in air at 250-280℃, and is particularly suitable as a substrate for flexible printed circuit boards and insulation for various high temperature motors and electrical appliances.

[0003] Announcement No. CN220802253U discloses a polyimide slurry filtration device, comprising a slurry filter tank with a discharge outlet and an inlet. An internally movable intermediate shaft is mounted inside the slurry filter tank, its lower end slidably inserted into a bushing connected to the discharge outlet. The upper end of the intermediate shaft is connected upwards to a drive mechanism, which enables the intermediate shaft to reciprocate up and down. From top to bottom, a first screen body, a second screen body, and a third screen body are sequentially arranged on the intermediate shaft. Each screen body has a plurality of first filter holes, a plurality of second filter holes, and a plurality of third filter holes evenly distributed on it. The diameter of the first filter holes is larger than that of the second filter holes, which is larger than that of the third filter holes. This invention primarily utilizes the drive mechanism to achieve the reciprocating up and down movement of the intermediate shaft, thereby creating a shaking effect on the first, second, and third screen bodies, thus increasing the slurry filtration speed and improving work efficiency.

[0004] The screen body filters the slurry by moving the intermediate shaft up and down through the drive mechanism. However, the funnel-shaped screen body will cause the slurry to gather towards the intermediate shaft, so that the slurry will flow along the outer wall of the intermediate shaft. The intermediate shaft and the bushing are connected by a movable interlocking connection, which will cause the slurry to flow out through the gap between the bushing and the intermediate shaft.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 The polyimide slurry filter shown includes a tank 1, with a feed pipe 3 for feeding and a discharge pipe 4 for discharging material at the top and bottom of the tank 1, respectively. A tank cover 2 for sealing the top of the tank 1 is also provided. The filter further includes:

[0025] Filter assembly 8 is used to filter slurry and is located inside tank 1;

[0026] Vibration component 5 is used to drive the filter component 8 to vibrate. Vibration component 5 includes a round rod 51 and a drive cylinder 52. The round rod 51 is used to connect and install with the filter component 8. The drive cylinder 52 is used to drive the round rod 51. The drive cylinder 52 is located at the top of the can cover 2. The round rod 51 is located at the output end of the drive cylinder 52.

[0027] Specifically, one end of the feed pipe 3 is connected through to one side of the tank body 1, the bottom end of the tank body 1 is connected through to the top end of the discharge pipe 4, the top end of the tank cover 2 is provided with a round hole, the round rod 51 is inserted into the round hole, the bottom end of the drive cylinder 52 is fixedly connected to the top end of the tank cover 2, the output end of the round rod 51 is provided with a linkage component, the linkage component includes a connecting plate 53, one side of the bottom end of the connecting plate 53 is fixedly connected to the output end of the drive cylinder 52, the other side of the bottom end of the connecting plate 53 is fixedly connected to the top end of the round rod 51, the inside of the tank body 1 is provided with a rod sleeve 6 for the round rod 51 to be inserted, and the outer wall of the rod sleeve 6 is fixedly connected with a fixing rod 7 for fixing the rod sleeve 6 and the inner wall of the tank body 1.

[0028] Furthermore, the contact points of the tank body 1, the inlet pipe 3, and the outlet pipe 4 are all welded together. The slurry is transported into the tank body 1 through the inlet pipe 3, and then filtered and output through the outlet pipe 4. A control valve is fitted on the outer wall of the outlet pipe 4 to control the discharge of slurry. The control valve is normally open when there is slurry inside the tank body 1 and closed when there is no slurry. The tank cover 2 is bolted to the tank body 1. The inner diameter of the sleeve 6 is matched with the diameter of the round rod 51, and the round rod 51 slides through the sleeve 6, which helps to maintain the round rod 51 when moving vertically. There will be no significant deviation. Two fixing rods 7 are welded to the outer wall of the rod sleeve 6. The ends of the fixing rods 7 away from the rod sleeve 6 are welded and fixed to the inner wall of the tank body 1, thereby fixing the position of the rod sleeve 6. The top of the rod sleeve 6 is 10cm above the bottom of the mounting frame 82, so that the filtered slurry accumulates inside the tank body 1 and will not flow out from the rod sleeve 6. The driving cylinder 52 is an existing electric cylinder. The output end of the driving cylinder 52 is bolted to the connecting plate 53. The connecting plate 53 is welded and fixed to the round rod 51. The extension and retraction of the output end of the driving cylinder 52 is controlled at intervals, thereby driving the round rod 51 to move at intervals.

[0029] Specifically, a fixing ring 10 is fixedly connected to the inner wall of the tank 1. A spring 9 for receiving the filter assembly 8 is provided at the top of the fixing ring 10. The filter assembly 8 includes a filter screen 81 and a mounting frame 82. The mounting frame 82 is sleeved on the outer wall of the filter screen 81. The vertical cross-section of the mounting frame 82 is W-shaped. The mounting frame 82 is located at the top of the spring 9. A through groove for inserting a round rod 51 is opened at the top of the mounting frame 82. Limiting members are respectively provided at the top and bottom of the mounting frame 82. A cavity for installing the limiting member is symmetrically opened inside the round rod 51. An insertion hole is opened on the inner wall of the cavity. The limiting member includes a limiting block 54. A baffle 55 is fixedly connected to the end of the limiting block 54. An elastic block 56 is provided on one side of the baffle 55.

[0030] Furthermore, the outer wall of the fixing ring 10 is welded and fixed to the inner wall of the tank 1. At least three springs 9 are provided, arranged in a ring at equal intervals at the top of the fixing ring 10. The bottom end of the spring 9 is bonded and fixed to the top of the fixing ring 10. Two limiting members are symmetrically arranged, respectively at the top and bottom of the circular hole position of the mounting frame 82. The vertical distance between the two limiting blocks 54 in the vertical direction is 1.5 times the thickness of the mounting frame 82. The size of the insertion hole is 1.02 times the size of the limiting block 54. The size of the baffle 55 is 1.2 times the size of the insertion hole. The elastic block 56 is existing elastic rubber. The elastic block 56 is always in a compressed state in the cavity. Baffles 55 are bonded to both ends of the elastic block 56. The baffles 55 are welded and fixed at the contact points with the limiting blocks 54. The limiting block 54 clamps the mounting frame 82. When the round rod 51 moves vertically upward, it drives the limiting block 54 to move synchronously, thereby pushing the mounting frame 82 to move synchronously. The filter screen 81 is made of metal mesh and is welded and fixed to the mounting frame 82. The filter screen 81 is set according to actual needs. When the round rod 51 moves vertically downward, it will cause instantaneous compression to the spring 9, thereby pushing the mounting frame 82 to move vertically upward. This causes the mounting frame 82 to vibrate continuously between the vertically set limiting blocks 54, causing the slurry collected at the bottom of the mounting frame 82 to be vibrated and drip. At the same time, the W-shaped design of the mounting frame 82 keeps the dripping part away from the round rod 51, thereby reducing the flow of slurry along the outer wall of the round rod 51.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
