Description

Technical Field

[0001] The utility model relates to an anti - sticking high - pressure plate - frame filter press, belonging to the technical field of plate - frame filter presses. Background Art

[0002] The plate - frame filter press was the first mechanical equipment applied to chemical dehydration. Currently, it is used in sewage treatment. Although its filtration capacity is relatively low, it still has advantages such as large filtration driving force, high solid content in the filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning chemicals.

[0003] Chinese Patent Publication (Publication No.: CN 211820168 U) discloses a high - pressure plate - frame filter press with a front - mounted integral threaded oil cylinder, which includes a filter frame and a filter plate assembly. The filter plate assembly includes a filter plate body, an oil cylinder, and a guiding connecting piece. An oil path is opened inside the filter plate body, and an oil cylinder installation hole communicating with it is opened on the oil path. The oil cylinder installation hole is connected to the oil cylinder. An internal thread is provided in the oil cylinder installation hole, and an integral external thread is provided on the outer side of the lower end of the mating oil cylinder. An external sealing groove is opened at a position on the outer side of the oil cylinder above the integral external thread, and an external sealing member is arranged in the external sealing groove. A piston rod is connected inside the oil cylinder. An internal sealing groove is opened at a position on the inner side of the oil cylinder above the integral external thread, and an internal sealing member is arranged in the internal sealing groove. The upper end of the piston rod abuts against the filter frame. The guiding connecting piece includes a guiding seat connected to the filter plate body. The guiding seat is connected to a guiding rod, and the upper end of the guiding rod is connected to the filter frame. For the high - pressure plate - frame filter press with the front - mounted integral threaded oil cylinder, the thread is in the front and the sealing member is in the rear, so the sealing member is not easily damaged and has a long service life.

[0004] However, when the above - mentioned technology uses a plate - frame filter press to recover the filter cake, there are situations where the filter cake is not easy to fall off and needs to be operated manually, which has a certain operation risk. Moreover, the filter residue attached to the filter plate is not easy to clean, affecting the normal operation next time. If the impurities in the filter frame cannot be cleaned in time, it cannot be operated normally during repeated use, delaying the normal processing progress.

[0005] Therefore, an anti - sticking high - pressure plate - frame filter press is proposed. Summary of the Utility Model

As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be essentially exemplary rather than restrictive.

[0027] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1

[0029] As Figures 1-5 shown, the embodiment of the present utility model provides an anti-sticking high-pressure plate-frame filter press, which includes a support frame 1, a filter frame 2 and a scraping mechanism 3. The filter frame 2 is movably connected inside the support frame 1. The top of the support frame 1 is connected to the scraping mechanism 3. The scraping mechanism 3 includes a fixed frame 301, a scraper 302 and a telescopic cylinder 303. The outer side of the support frame 1 is fixedly connected to the fixed frame 301. The top of the fixed frame 301 is fixedly connected to the bottom of the telescopic cylinder 303. The bottom of the telescopic cylinder 303 is movably connected to the top of the scraper 302. The inner side of the scraper 302 is in contact with the outer side of the filter frame 2. A sliding groove 4 is opened at the top of the support frame 1. The filter frame 2 is slidably connected inside the sliding groove 4. A number of friction blocks 5 are arranged on the inner side of the scraper 302. The inner side of the friction blocks 5 is in close contact with the outer surface of the filter frame 2. Empty grooves 6 are opened on both the left and right sides of the telescopic cylinder 303. The empty grooves 6 are divided into two layers. The inner sides of the two scrapers 302 are movably connected inside the empty grooves 6. The bottoms of the two scrapers 302 are wedge-shaped.

[0030] Through the scraping mechanism 3, when cleaning the impurities on the filter frame 2, the telescopic cylinder 303 can drive the scraper 302 to move up and down to scrape the impurities attached to the surface of the filter frame 2, which is convenient for the staff to operate. By setting the friction blocks 5, the filter frame 2 after scraping can be rubbed to enhance the cleaning effect on the surface of the filter frame 2.

[0031] Embodiment 2

[0032] In one embodiment, a positioning block 7 is fixedly connected to the top of the telescopic cylinder 303. A positioning cavity 8 is opened inside the positioning block 7. A positioning mechanism 9 is arranged inside the positioning cavity 8. The positioning mechanism 9 includes a moving rod 901, a positioning rod 902 and a tension spring 903. The top of the moving rod 901 penetrates through the top of the positioning cavity 8. The top of the moving rod 901 penetrates into the positioning cavity 8. The bottom of the moving rod 901 is fixedly connected to the top of the positioning rod 902. The top of the positioning rod 902 is fixedly connected to the top of the tension spring 903. The bottom of the tension spring 903 is fixedly connected to the inner wall of the positioning cavity 8. The top of the positioning rod 902 penetrates into the scraper 302. Three fixing grooves 10 are opened at the top of the scraper 302. When the positioning rod 902 is inserted into the fixing grooves 10, they are in close contact.

[0033] Through the positioning mechanism 9, when cleaning the filter frames 2 with different widths, the moving rod 901 can be pulled. The moving rod 901 drives the positioning rod 902 to move, facilitating the staff to adjust the width of the scraping plate 302 and increasing the applicability of the overall device. By setting the fixing groove 10, when the positioning rod 902 is inserted and fixed, it can be accurately inserted into the interior of the fixing groove 10.

[0034] When the present utility model is working: Pull the moving rod 901 upwards. While the moving rod 901 drives the positioning rod 902 to move upwards, the tension spring 903 is stretched, causing the positioning rod 902 to move into the positioning cavity 8. At this time, the scraping plate 302 can be adjusted according to the different widths of the filter frames 2. After completion, release the moving rod 901. Due to the pulling force of the tension spring 903, the positioning rod 902 is reinserted into the interior of the fixing groove 10. At this time, the device can be started. When the filter frame 2 moves to the middle part, stop moving and start the telescopic cylinder 303. The telescopic cylinder 303 pushes the scraping plate 302 downwards, and the impurities attached to the surface of the filter frame 2 are cleaned and scraped off through the inner side of the scraping plate 302. After completion, the telescopic cylinder 303 drives the scraping plate 302 to move upwards to complete the scraping of the filter plate. The movement of the filter frame 2 can be continued to scrape the next filter frame 2 to prevent the filter frame 2 from sticking to materials.

[0035] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
