Description

Technical Field

[0001] This utility model belongs to the field of thin film technology and relates to a melt filter disc cleaning device. Background Technology

[0002] In continuous PET production units, the material (melt) contains impurities and particles. To ensure the final product quality, online filters, namely melt filters, are installed after the material pumps in the pre-polymerization and final polymerization stages. Melt filters are typically available in several filtration precisions, such as 15μm, 20μm, 25μm, and 40μm. The melt filter separates particles and impurities larger than the filtration precision from the material. As the unit operates, impurities accumulate in the melt filter. The pressure probes of the filter's feed and discharge systems provide real-time feedback on the system pressure. Once the detected pressure difference reaches a set value, a standby filter is switched. The material in the switched-off filter cartridge is gradually discharged. After it is mostly drained, the filter cartridge is disassembled, the melt filter discs are removed, and the melt filter discs are cleaned.

[0003] Melt filter discs are made of stainless steel or other corrosion-resistant materials with a series of tiny pores. Currently, cleaning primarily uses ultrasonic cleaning devices to clean the discs in the filter element. However, since a filter contains hundreds of discs, a large number of discs accumulate in the ultrasonic cleaning device, inevitably leading to some discs not being completely cleaned. The numerous impurity particles within the discs are difficult to remove using ultrasonic cleaning alone. In such cases, melt filter discs with black spots need to be selected and placed in a high-temperature cleaning furnace to remove the melt using chemical reagents. However, the melt filter discs are still not completely clean because the impurity particles still contain metal particles, which cannot be removed by chemical reagents. Patent CN205127556U discloses a melt filter cleaning system that uses superheated steam to clean the melt particles accumulated inside the melt filter. However, the temperature of the steam alone is insufficient to affect the metal particle impurities, making it impossible to thoroughly clean the melt filter discs.

[0004] Therefore, it is of great significance to study a melt filter disc cleaning device that can clean metal particle impurities after cleaning melt particles on the melt filter disc. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art and to provide a melt filter disc cleaning device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] The rotating fixing mechanism is used to fix the melt filter disc and drive the melt filter disc to rotate; when the melt filter disc is fixed to the rotating fixing mechanism, the melt filter disc is parallel to the inclined plate;

[0009] The vibration mechanism is fixedly connected to the inclined plate; the vibration mechanism is used to vibrate the melt filter disc when the melt filter disc rotates, thereby causing the metal particles to fall off.

[0010] As a preferred technical solution:

[0011] The melt filter disc cleaning device described above includes a rotating and fixing mechanism comprising an air shaft, a limiting flange, a bearing, a bearing housing, a transmission gear, and a drive motor.

[0015] The lower end of the shaft body passes through the bearing and is fixedly connected to the inner ring of the bearing, while the outer ring of the bearing is fixedly connected to the bearing housing. A through hole A is provided on the inclined plate, and the air shaft is located above the inclined plate and perpendicular to it.

The transmission gear is located below the inclined plate and is fitted onto the shaft body and fixedly connected to it. The drive motor is located below the inclined plate. A drive gear is fitted onto the motor shaft of the drive motor, and the drive gear is fixedly connected to the motor shaft and meshes with the transmission gear.

[0020] The clamp is a rectangular plate I with a through hole B. The rectangular plate I is fitted with the handle of the vibrating gun through the through hole B, thereby fixing the vibrating gun on the clamp.

[0021] The clamping plate is slidably connected to the fixed column, and the clamping plate slides along the length of the fixed column, thereby controlling the distance between the vibrating head of the vibrating gun and the melt filter disc when the melt filter disc is fixed on the expansion assembly.

[0022] The limiting and fixing device is used to fix the relative position of the clamp and the fixing column.

[0023] As described above, in a melt filter disc cleaning device, the through hole B is a circular through hole; the handle of the vibrating gun is cylindrical.

[0024] As described above, the limit fixing device for a melt filter disc cleaning device includes a rectangular plate II, a nut, and a bolt;

[0065] like Figure 1 , Figure 6 , Figure 7 As shown, the vibration mechanism includes a support frame and a vibration gun 5;

[0066] The bracket includes a fixed column 4, a clamping plate 6, and a limiting and fixing device;

[0067] The fixed column 4 is a hollow cubic structure; along the length direction perpendicular to the fixed column 4, the cross-section of the fixed column 4 is a square ring structure; the fixed column 4 is fixed to the upper surface of the inclined plate 18, and the length direction of the fixed column 4 is perpendicular to the inclined plate 18.

When the distance between the bolt head and side A is equal to the length of through hole C and through hole D, the relative positions of clamping plate 6 and fixing post 4 are fixed, and plate I and plate II are in contact. When the distance between the bolt head and side A is greater than the length of through hole C and through hole D, the relative positions of clamping plate 6 and fixing post 4 are not fixed.

[0074] The handle 23 of the vibrating gun 5 is cylindrical, and the rectangular plate I is fitted with the handle 23 of the vibrating gun 5 through the through hole B. When the melt filter disc 21 is fixed on the expansion assembly, the vibrating head 22 of the vibrating gun 5 faces the lower surface of the melt filter disc 21. When the relative positions of the clamping plate 6 and the fixing post 4 are not fixed, the clamping plate 6 is slidably connected to the fixing post 4, and the clamping plate 6 can slide along the length direction of the fixing post 4, thereby controlling the distance between the vibrating head 22 of the vibrating gun 5 and the melt filter disc 21 when the melt filter disc 21 is fixed on the expansion assembly.

[0083] The process of using the above device is as follows: Figure 1 , Figure 4 , Figure 5 As shown, first place the melt filter disc 21 to be cleaned on the air shaft 2. Due to the setting of the limiting flange 3, the melt filter disc will be positioned at the limiting flange 3. Then, turn on the power switch 9 and the air shaft tensioning switch 7 in sequence to control the expansion of the expansion component to lock the melt filter disc 21. Then, install the vibrating gun 5 in the clamping plate 6. After adjusting the position of the vibrating gun 5, bring the vibrating head 22 of the vibrating gun 5 close to the lower surface of the disc 21 until there is a 3mm gap between the vibrating head 22 and the melt filter disc 21. After adjusting the position of the vibrating gun 5, fix it with the clamping plate 6 to prevent the vibrating gun 5 from loosening.

[0084] Next, adjust the motor speed adjustment knob 10 to 40 rpm. The melt filter disc 21 will rotate synchronously with the air shaft 2. At this time, adjust the vibration gun frequency adjustment knob 11 to 50 Hz to adjust the vibration frequency of the vibration gun 5. This will cause the vibration gun 5 to continuously strike the melt filter disc 21 at a high frequency, so that small impurities on the melt filter disc 21 will fall off continuously until no impurities are observed to fall off, indicating that the melt filter disc 21 has been cleaned. Finally, adjust the motor speed adjustment knob 10 to 0 rpm and adjust the vibration gun frequency adjustment knob 11 to 0 Hz. Then, turn off the air shaft tension switch 7 to make the control expansion component contract. At this time, the cleaned melt filter disc 21 can be easily removed. If more melt filter discs 21 need to be cleaned, repeat the above steps.
