Description

Technical Field

[0001] This invention relates to the field of mica paper filtration, specifically to a splash-proof mica slurry filtration device. Background Technology

[0002] Mica paper, one of the most widespread applications of mica, is made from mica flakes through crushing, pulping, and papermaking. It often possesses most of the properties of its counterparts in sheet mica products and is widely used industrially as an insulating material in cables and large electromechanical equipment. The mica paper production process mainly includes seven steps: crushing, grading, pulping, papermaking, forming, pressing, and drying. One step in production requires filtering the slurry with filter paper. However, during use, the filter paper is usually not perfectly flat, leading to mica slurry accumulation on it. Current technology typically uses vibration to dissipate the accumulated mica slurry, but because the filter paper is uneven, the mica slurry tends to pool during flow. Vibration further agitates and splashes the slurry, causing it to splatter across various parts of the equipment and requiring frequent cleaning. To address these issues, we have designed an anti-splash mica slurry filtration device. Summary of the Invention

[0003] The technical problem to be solved by this technical solution is: how to reduce vibration when guiding the flow of mica slurry, so as to avoid splashing of mica slurry.

[0004] To achieve the above objectives, the technical solution adopted by this device is as follows: a splash-proof mica slurry filtration device, which includes an inclined screen plate, on which filter paper is laid flat for filtration. The screen plate is positioned between the slurry conveying trough and the feeding pipe. A water conveying trough is provided below the screen plate. Side plates are provided on both sides of the screen plate. A pressure rod is provided above the screen plate. The pressure rod has placement holes for placing telescopic columns spaced along its length. Cams for driving the pressure rod to move downward are provided above both ends of the pressure rod, and springs for driving the pressure rod to move upward are provided below both ends of the pressure rod.

[0005] The beneficial effects of this technical solution are as follows: the pressure rod is driven by the cam and spring to move up and down periodically. During the periodic movement of the pressure rod, the telescopic column on the pressure rod will continuously contact the filter paper on the screen plate. When the telescopic column contacts the filter paper, it will press the protrusion on the filter paper, causing the filter paper to deform, thereby guiding the flow of the accumulated mica slurry. The telescopic column will also retract upwards, thereby preventing the filter paper from vibrating significantly.

[0006] The technical problem that this improved technical solution aims to solve is: how to make more areas on the filter paper come into contact with the filter paper.

[0007] To achieve the above objectives, the device is further improved by including sliding plates on both sides of the sieve plate, a rotating rod between the sliding plates, lifting columns spaced along the length of the rotating rod, an inclined surface on the upper end of the sliding plate, and the sliding plates being slidably mounted on the side plate.

[0008] The beneficial effects of this improved technical solution are as follows: by pressing the sliding plate with the pressure rod, the sliding plate is moved upward. As the sliding plate moves, it drives the rotating rod to rotate, so that the telescopic column on the rotating rod periodically contacts the filter paper. At the same time, under the action of the limiting groove, the sliding plate will not slide away from the pressure rod.

[0009] The technical problem to be solved by this improved technical solution is: how to make the sliding plate slide smoothly and how to make the rotating rod rotate smoothly.

[0010] To achieve the above objectives, the device is further improved in that: a support bar for supporting the sliding plate is provided on the side plate, a rack is provided on the side end of the support bar, and gears that mesh with the rack are connected to both sides of the rotating rod.

[0011] The beneficial effects of this improved technical solution are as follows: the sliding plate is supported by a support bar, and a rack is provided on the side end of the support bar. The rack is engaged by a gear next to the rotating rod, so that the rotating rod is driven to rotate when the sliding plate moves.

[0012] The technical problem to be solved by this improved technical solution is: how to smoothly drive the sliding plate to move when the pressure rod is pressed down.

[0013] To achieve the above objectives, a further improvement of this device is that a roller is provided on the pressure rod, and the roller rolls on the upper surface of the sliding plate.

[0014] The beneficial effect of this improved technical solution is that friction is reduced by rotating the bearing, thereby smoothly driving the sliding plate to move.

[0015] The technical problem to be solved by this improved technical solution is: how to increase the pressure on the filtrate and enhance the filtration effect when the telescopic column is pressed.

[0016] To achieve the above objectives, a further improvement to this device is that a compression plate is connected to the lower end of the telescopic column.

[0017] The beneficial effects of this improved technical solution are: the extrusion plate is moved by the telescopic column, thereby effectively enhancing the filtration effect.

[0018] The technical problem to be solved by this improved technical solution is: how to enable the pressure bar to move and return to its original position quickly and effectively.

[0019] To achieve the above objectives, the device is further improved in that: the side plate is provided with a placement groove for placing the spring, and the two ends of the pressure rod extend out of the side plate and fit against the cam.

[0020] The beneficial effects of this improved technical solution are: a spring is provided between the side plate and the cam, which enables the pressure rod to move and return effectively.

[0021] The technical problem to be solved by this improved technical solution is: how to make the cam smoothly drive the pressure rod to move.

[0022] To achieve the above objectives, a further improvement to this device is that a square plate is provided at the contact point between the pressure rod and the cam.

[0023] The beneficial effect of this improved technical solution is that the square plate increases the contact area with the cam, thereby allowing the cam to smoothly drive the pressure rod to move.

[0024] The technical problem to be solved by this technical solution is to prevent the pressure rod from moving in other directions.

[0025] To achieve the above objectives, the device is further improved in that: a sliding shaft is provided in the placement groove, a spring for supporting the pressure rod is provided on the sliding shaft, and both ends of the pressure rod are sleeved on the sliding shaft.

[0026] The beneficial effect of this improved technical solution is that the pressure rod is restricted by the sliding shaft, so that the pressure rod can only move up and down.

[0027] The technical problem to be solved by this technical solution improvement is: to prevent the pressure rod from rising and falling within a fixed range.

[0028] To achieve the above objectives, a further improvement to this device is that the upper end of the sliding shaft is threadedly connected to the stop block.

[0029] The beneficial effect of this improved technical solution is that the rising height of the pressure rod is limited by the stop block, so that the pressure rod rises and falls within a fixed range.

[0030] The technical problem to be solved by this improved technical solution is: how to make the pressure bar at different positions move periodically so that the slurry can further reduce vibration while flowing.

[0031] To achieve the above objectives, the device is further improved in that the cam is mounted on a rotating shaft connected to the drive motor, and the upper and lower adjacent cam protrusions are staggered.

[0032] The beneficial effects of this improved technical solution are as follows: by rotating the cam together with the rotating shaft, and by adjusting the initial state of the cam, the pressure rods move sequentially from top to bottom, so that the slurry flows from top to bottom, and the multiple pressure rods do not press the filter paper at the same time, thereby further reducing the vibration of the filter paper.

[0046] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0047] Example 1: Combination Figure 1 , Figure 2 , Figure 4 , Figure 5 It includes an inclined screen plate 1, on which filter paper 6 is laid flat for filtration. The screen plate 1 is located between a pulp conveying trough 9 and a feeding pipe 11. A water conveying trough 10 is located below the screen plate 1. The screen plate 1 is characterized by having side plates 2 on both sides and a pressure rod 4 on top. The pressure rod 4 has placement holes 5 for placing telescopic columns 52 at intervals along its length. Cams 8 for driving the pressure rod 4 to move downward are located above both ends of the pressure rod 4, and springs 42 for driving the pressure rod 4 to move upward are located below both ends of the pressure rod 4. In this embodiment, the telescopic column 52 is composed of a hollow steel column with a movable and liftable lower end and a fixed steel column at the upper end. When not in contact with the filter paper, the lower steel column of the telescopic column 52 naturally falls to its lowest height due to gravity. When the pressure rod 4 descends, the telescopic column 52 comes into contact with the filter paper, causing the filter paper to vibrate slightly. When the pressure rod descends to its lowest point, the hollow steel column completely enters the upper fixed steel column, causing the lower hollow steel column to make hard contact, thus generating greater vibration. Due to the action of the cam 8 and the spring 42, the pressure rod 4 can quickly and periodically rise and fall, thereby preventing the telescopic column 52 from pressing the filter paper for a long time.

[0048] Example 2: Combination Figures 4-12 As a further optimization of the above embodiment, it also includes sliding plates 12 located on both sides of the sieve plate 1. A rotating rod 13 is arranged between the sliding plates 12, and lifting columns 53 are spaced along the length direction on the rotating rod 13. The upper end surface of the sliding plate 12 is an inclined surface, and the sliding plate 12 is slidably arranged on the side plate 2. In this embodiment, the sliding plate 12 is inclined in the same direction as the sieve plate 1. When the pressure rod 4 moves downward, the pressure rod 4 presses the sliding plate 12, causing the sliding plate 12 to move upward. When the pressure rod 4 moves upward, the sliding plate 12 moves downward due to gravity. When the sliding plate 12 moves up and down, it drives the lifting columns 53 on the rotating rod 13 to contact multiple positions of the filter paper, thereby increasing the pressing range of the filter paper. In this embodiment, the side plate 2 is slidably connected to the sliding plate 12 through a limiting groove 16. The limiting groove 16 restricts the movement path of the sliding plate 12, thereby preventing the sliding plate 12 from detaching from the pressure rod 4.

[0049] Example 3: Combination Figures 4-12As a further optimization of the above embodiment: the side plate 2 is provided with a support bar for supporting the sliding plate 12, and a rack 15 is provided at the side end of the support bar. Gears 14 meshing with the rack 15 are connected to both sides of the rotating rod 13. The sliding plate 12 is supported by the support bar, and the rack 14 is provided at the side end of the support bar. The gears 15 next to the rotating rod mesh with the rack 14, so that when the sliding plate 12 moves, it drives the rotating rod 13 to rotate, thereby preventing the lifting column 53 on the rotating rod 13 from constantly contacting the filter paper and thus pressing down the filter paper.

[0050] Example 4: Combination Figures 2-6 As a further optimization of the above embodiment: a roller is provided on the pressure rod 4, and the roller rolls on the upper end face of the sliding plate 12. In this embodiment, the roller is in a rolling connection with the pressure rod 4, which reduces friction and prevents slippage between the pressure rod 4 and the sliding plate 12, thus smoothly driving the sliding plate to move.

[0051] Example 5: Combination Figures 5-6 The lower end of the telescopic column 52 is connected to a squeezing plate. In this embodiment, the squeezing plate can be square or round; in this embodiment, a square plate is selected. By setting a squeezing plate at the lower end of the telescopic column 52, the pressing area is increased, and a certain pressure is increased to promote the separation and filtration effect. Since multiple telescopic columns 52 are set at the same time, when the telescopic column 52 contacts the filter paper, it can effectively flatten the filter paper, so that the liquid that was originally gathered on the filter paper can be evenly distributed on the filter paper.

[0052] Example 6: Combination Figures 5-6 As a further optimization of the above embodiment: the side plate 2 is provided with a placement groove for placing the spring 42, and the two ends of the pressure rod 4 extend out of the side plate 2 and are in contact with the cam 8. The cam 8 is provided at both ends of the pressure rod 4, and the spring 42 is provided on the side plate 2, so that the pressure rod 4 can be effectively raised and lowered.

[0053] Example 7: Combination Figure 1 As a further optimization of the above embodiment: a square plate is provided at the contact point between the pressure rod 4 and the cam 8. In this embodiment, the pressure rod is circular, and the length, width, and thickness of the square plate are all greater than the diameter of the pressure rod. The square plate increases the contact area with the cam, thereby allowing the cam to smoothly drive the pressure rod to move. In this embodiment, the cam 8 is arranged opposite to each other at both ends of the pressure rod 4, and their rotation directions are opposite.

[0054] Example 8: Combination Figures 1-8As a further optimization of the above embodiment, a sliding shaft is provided in the placement groove, and a spring for supporting the pressure rod 4 is mounted on the sliding shaft. Both ends of the pressure rod 4 are sleeved on the sliding shaft. The sliding shaft restricts the pressure rod 4, so that the pressure rod 4 can only move up and down, avoiding misalignment caused by left and right movement of the pressure rod 4.

[0055] Example 9: Combination Figures 1-8 As a further optimization of the above embodiment, the upper end of the sliding shaft is threadedly connected to the stop block. The thread restricts the pressure rod 4, allowing it to move up and down only within a specific area. The stop block can be disassembled via the thread, facilitating the installation of the pressure rod.

[0056] Example 10: Combination Figures 1-3 As a further optimization of the above embodiment: the cam 8 is disposed on the rotating shaft 7 connected to the drive motor, and the protrusions of adjacent cams 8 are staggered. In this embodiment, the protrusions of the cam 8 rotate 90° sequentially from top to bottom; the cam has four states. When the drive motor drives the rotating shaft to the initial state, all cams do not press the pressure plates. When the rotating shaft rotates 90°, the uppermost cam drives its corresponding pressure plate to swing downward, while the other pressure plates remain stationary. When the rotating shaft rotates 180°, the uppermost pressure plate bounces back upward after swinging, and the middle pressure plate swings downward. When the rotating shaft rotates 270°, the middle pressure plate bounces back upward after swinging, and the lowermost pressure plate swings downward. When the rotating shaft rotates 360°, the lowermost pressure plate bounces back upward after swinging, and all pressure plates are in the initial state.

[0057] Detailed Implementation: When using this device, filter paper 6 is placed on the sieve plate 1, and the drive motor is started to drive the rotating shaft 7 to rotate and the cam 8 to rotate. Since the protrusions of the cam 8 are staggered from top to bottom, when the rotating shaft 7 rotates, the cam 8 from top to bottom presses the corresponding pressure rod 4 in sequence, causing the pressure rod 4 to descend in sequence. This causes the telescopic column 52 on the pressure rod 4 to contact the filter paper in sequence, preventing all pressure rods from contacting and vibrating the filter paper. This causes the filter paper to vibrate in sequence from top to bottom, allowing the accumulated slurry to flow slowly from top to bottom. A sliding plate 12 is provided below the pressure rod 4. When the pressure rod 4 is pressed down, the sliding plate 12 moves upward. When the pressure rod 4 rises, the sliding plate 12 moves downward due to gravity. Since the rotating rod 13 on the sliding plate 12 meshes with the rack 15 on the side plate 2, the rotating rod 13 rotates synchronously when the sliding plate 12 slides, causing the lifting column 53 on the rotating rod 13 to contact the filter paper, thereby vibrating the filter paper between the pressure rods 4 and preventing slurry accumulation. Meanwhile, since there are multiple telescopic columns 52 and lifting columns 53, when pressed, the originally uneven filter paper can be flattened, so that the water flow on the filter paper can flow evenly and avoid water flow convergence. The converged water flow has a greater impact force and is more difficult to filter. At the same time, due to the presence of the extrusion plate, the accumulated slurry can be further squeezed, so that the slurry can be further filtered and separated, thereby improving the purity.
