Description

Technical Field

[0001] This utility model relates to the field of filter press installation and alignment technology, specifically an automatic alignment auxiliary device for filter press installation. Background Technology

[0002] A filter press is a commonly used solid-liquid separation device, widely used in chemical, metallurgical, food, and environmental protection fields. Its main function is to separate solids and liquids by pressurizing the liquid in a suspension through a filter medium such as a filter cloth, thereby trapping solid particles.

[0003] Traditional filter press installation relies heavily on manual measurement and experience, lacking effective automatic alignment auxiliary devices. Installers often determine the crossbeam position by visual observation and simple ruler measurements. This method is greatly affected by human factors and cannot guarantee high precision in crossbeam installation. When the crossbeam cannot be accurately aligned, uneven force will occur on the filter plates during pressing and unfolding, leading to a significant increase in friction between the filter plates. This, in turn, increases the resistance in the filtration process, not only increasing the energy consumption of the equipment but also accelerating the wear of components such as filter plates and sealing rings, shortening the service life of the filter press, and reducing filtration efficiency and filtration quality. To address this, we propose an automatic alignment auxiliary device for filter press installation. Utility Model Content

The side wall has a guide hole 16 that engages with the guide rod 13. The crossbeam is moved under the drive of the motor 4. Threaded adjusting rod 6: The threaded adjusting rod 6 has a rotating handle at the top and a limiting block 17 in the middle, which is threadedly connected to the support column 7. When the handle is rotated, the support column 7 is driven to rise and fall in the adjusting cylinder 8, so as to realize the horizontal adjustment of the base 1. Support column 7: The support column 7 is hollow inside, with a threaded bushing 18 at the top that cooperates with the threaded adjusting rod 6, and the bottom is retractable. The guide slider 19 on the outer side of the top slides with the guide groove 10 to help adjust the level of the base 1. Adjusting cylinder 8: The adjusting cylinder 8 is located at the top four corners of the base 1. The top has a limiting cavity 9, the bottom is open, and the inner wall has a guide groove 10 to accommodate the horizontal fine adjustment component and provide guiding space for the lifting and lowering of the support column 7. Limiting cavity 9: The limiting cavity 9 is located inside the top of the adjusting cylinder 8 and is used to engage the limiting block 17 of the threaded adjusting rod 6, limiting the range of motion of the threaded adjusting rod 6 and ensuring the stability and accuracy of the horizontal adjustment process; Guide groove 10: The guide groove 10 is arranged in a ring array on the inner wall of the adjusting cylinder 8, and cooperates with the guide slider 19 on the top of the support column 7 to ensure that the support column 7 remains stable during lifting and adjusting and to prevent deviation. Slotted support column 11: The slotted support column 11 consists of four axially symmetrically distributed structures on the top of the base 1, which slide in conjunction with the block sliding column 14 at the bottom of the lifting platform 2 to ensure the stability of the lifting platform 2 during the lifting process. Slide cavity 12: Slide cavity 12 consists of two axially connected cavities opened at the top of the lifting platform 2. Guide rods 13 are installed inside to accommodate the slider 15 supporting the bottom of the slide plate 5, providing a moving track for fine adjustment of the crossbeam. Guide rod 13: The guide rod 13 consists of two rod-shaped structures that are axially symmetrically distributed in the sliding cavity 12. They slide and engage with the guide hole 16 on the side wall of the supporting slide plate 5 to ensure the stability of the supporting slide plate 5 when it moves. Block sliding column 14: Block sliding column 14 consists of four structures symmetrically distributed at the bottom of the lifting platform 2, which slide in cooperation with the slotted support column 11 at the top of the base 1 to ensure the stability and accuracy of the lifting platform 2 during lifting. Slider 15: Slider 15 is located at the bottom center of the support slide plate 5 and slides in the slide cavity 12. It is equipped with a threaded bushing inside and connected to the output shaft of the motor 4. Under the drive of the motor, it moves the support slide plate 5. Guide hole 16: The guide hole 16 is a hole-shaped structure that is symmetrically distributed on the side wall of the support slide plate 5. It slides and engages with the guide rod 13 in the slide cavity 12 to enhance the stability and guidance of the support slide plate 5 when it moves. Limiting block 17: The limiting block 17 is located in the middle section of the threaded adjusting rod 6 and engages with the limiting cavity 9 of the adjusting cylinder 8 to limit the movement trajectory of the threaded adjusting rod 6 and ensure the reliability of the horizontal adjustment operation. Threaded bushing 18: The threaded bushing 18 is located at the top of the inside of the support column 7 and is threadedly engaged with the threaded adjusting rod 6. When the threaded adjusting rod 6 rotates, it drives the support column 7 to achieve the lifting and lowering action. Guide slider 19: The guide slider 19 is a structure with a ring array distributed on the outer side of the top of the support column 7. It slides and engages with the guide groove 10 on the inner wall of the adjusting cylinder 8 to ensure that the support column 7 rises and falls smoothly. Leveling instrument 20: The leveling instrument 20 is installed at the center of the top end face of the base 1, and detects the levelness of the base 1 in real time and feeds back the data, providing a basis for the adjustment of the leveling fine adjustment component.

[0028] Working Principle: Install the automatic centering auxiliary device for the filter press according to the diagram. During operation, first use the leveling fine-tuning component to level the entire auxiliary support assembly. Rotate the handle at the top of the threaded adjusting rod 6. Since the threaded adjusting rod 6 is threadedly connected to the support column 7, and the limiting block 17 in the middle section of the threaded adjusting rod 6 is engaged inside the limiting cavity 9 of the adjusting cylinder 8, rotating the threaded adjusting rod 6 will cause the threaded bushing 18 to drive the support column 7 to rise and fall inside the adjusting cylinder 8. The guide slider 19 on the outer side of the top of the support column 7 slides with the guide groove 10 on the inner wall of the adjusting cylinder 8, ensuring smooth lifting. The leveling detector 20 at the center of the top end face of the base 1 detects the levelness of the base 1 in real time and feeds back the data. Adjust the leveling fine-tuning component according to the data to make the base 1 level. After completing the leveling adjustment, if it is necessary to adjust the height of the two crossbeams to be installed, the control system controls the base 1 and the lifting platform 2 to be aligned axially. Two symmetrically distributed electric push rods 3 have top output push rods that drive the lifting platform 2. Due to the sliding engagement between the block slide column 14 at the bottom of the lifting platform 2 and the slotted support column 11 at the top of the base 1, the lifting platform 2 is able to rise and fall smoothly, thereby driving the crossbeam at the top of the lifting platform 2 to adjust its height. The crossbeam's position is finely adjusted by the crossbeam fine-adjustment component. The motor 4 is fixed to the side wall of the lifting platform 2 by adapter bolts. Its output shaft is a two-section bidirectional threaded rod that passes through the two slide cavities 12. The slider 15 at the bottom center of the support slide plate 5 slides inside the slide cavity 12. The threaded bushing inside the slider 15 engages with the output shaft of the motor 4. The guide hole 16 on the side wall slides with the guide rod 13 inside the slide cavity 12. When the motor 4 is working, the output shaft rotates, which drives the two support slide plates 5 to move through the threaded bushing inside the slider 15, thereby controlling the spacing between the two crossbeams placed on top of the support slide plate 5, achieving precise fine-tuning of the crossbeams, and completing automatic centering.
